통상적으로 사용되는 용기 개폐용 캡은, 캡을 개방하고자 하는 사용자에 의해 용기의 제조 단계 이후 최초로 캡이 회전하여 개방될 때, 캡의 상부와 하부가 파단이 일어나면서 서로 분리되는 것을 특징으로 한다.Commonly used container opening and closing caps are characterized in that when the cap is rotated and opened for the first time after the manufacturing step of the container by a user who wants to open the cap, the upper and lower portions of the cap are broken and separated from each other.
도면을 참조하여 설명하면, 도 1은 종래 용기의 상부에 대한 투시 정면도이며, 도 1에 도시된 바와 같이 용기의 입구에 결합된 캡은 상부에 해당하는 본체(1)와, 하부에 해당하는 고정링(2)으로 구성된다. 또한, 본체(1)와 고정링(2)의 사이에는 연결부(3)가 구비되어, 사용자에 의해 최초로 캡이 개방될 때 연결부(3)를 구성하는 복수의 연결 팁이 모두 끊어지면서 본체(1)와 고정링(2)이 서로 분리된다. 이때 복수의 연결 팁이 끊어지는 소리에 의하여, 또는 개방 전 복수의 연결 팁이 결합된 상태의 형상에 의하여, 사용자는 해당 용기가 이전에 개봉되지 않은 용기임을 간접적으로 확인 받을 수 있다. Referring to the drawings, FIG. 1 is a perspective front view of an upper portion of a conventional container, and as shown in FIG. 1, the cap coupled to the inlet of the container has a main body 1 corresponding to the upper portion and a fixing corresponding to the lower portion. It consists of a ring (2). In addition, a connection part 3 is provided between the main body 1 and the fixing ring 2, and when the cap is first opened by the user, the plurality of connection tips constituting the connection part 3 are all cut off and the main body 1 ) And the retaining ring (2) are separated from each other. At this time, the user can indirectly confirm that the container is a container that has not been previously opened by the sound of the plurality of connection tips being disconnected, or by the shape of a state in which the plurality of connection tips are combined before opening.
여기서, 본체(1)의 내주면에는 나사산이 구비되어 본체(1) 부분은 회전에 의해 용이하게 용기로부터 분리되나, 내주면에 걸림턱이 구비되는 고정링(2)은 용기 상부에 형성된 고정턱에 걸림으로써 사용자가 고정링(2)을 용기로부터 분리하는 것이 용이하지 않다. Here, a thread is provided on the inner circumferential surface of the main body 1 so that the main body 1 is easily separated from the container by rotation, but the fixing ring 2 provided with a locking protrusion on the inner circumferential surface is caught by the fixing jaw formed on the top of the container As a result, it is not easy for the user to separate the fixing ring 2 from the container.
고정링(2)이 용기로부터 분리되지 않고 용기 입구에 잔류하게 되는 것은, 사용자가 용기로부터 캡을 개폐하는데 있어서는 크게 문제되지 않으나, 사용자가 용기를 사용한 이후에 용기를 재활용하는 단계에서 상당한 문제가 된다. 즉, 용기 제조 시 용기 바디와 캡(즉, 고정링(2))은 서로 다른 재료로 구성이 되므로, PET 용기와 같은 용기의 재활용을 위해서는 고정링(2)을 용기 바디로부터 분리해야만 한다. The fact that the retaining ring 2 is not separated from the container and remains at the mouth of the container is not a big problem for the user to open and close the cap from the container, but it becomes a significant problem in the step of recycling the container after the user has used the container. . That is, when the container is manufactured, since the container body and the cap (ie, the fixing ring 2) are made of different materials, the fixing ring 2 must be separated from the container body in order to recycle a container such as a PET container.
또한 고정링(2)이 용기로부터 분리되지 않고 용기 입구에 잔류하게 되면, 사용자가 용기 입구로부터 직접 입으로 그 내용물을 흡인하는 경우에 외부에 노출되어 있던 고정링(2)이 사용자의 입술에 접촉하게 됨으로써 위생상의 문제점이 대두될 수 있다. In addition, if the retaining ring 2 is not separated from the container and remains at the mouth of the container, the retaining ring 2 exposed to the outside comes into contact with the user's lips when the user sucks the contents by mouth directly from the container inlet. As a result, hygiene problems may arise.
하지만, 걸림턱의 작용으로 통상의 사용자들은 쉽게 고정링(2)을 빼낼 수 없고, 또한 대부분의 사용자들이 고정링(2)을 따로 분리배출 해야한다는 사실에 대하여 정확한 인식을 가지고 있지 않다. 이에 따라, 쓰레기의 수거 또는 재사용 단계에서 별도의 인력과 많은 비용이 투입되어 용기로부터 고정링(2)을 끊어내는 작업이 수행되고 있다.However, due to the action of the locking jaw, ordinary users cannot easily pull out the fixing ring 2, and most users do not have an accurate recognition of the fact that the fixing ring 2 has to be separated and discharged separately. Accordingly, in the step of collecting or reusing garbage, a separate manpower and a large amount of cost are put in, and the operation of disconnecting the fixing ring 2 from the container is being performed.
본 발명은 상기 문제점을 해결하기 위한 것으로서, 캡의 하부에 해당하는 고정링의 일부 영역이 용기 입구의 고정턱에 걸리지 않도록 함으로써, 고정링이 캡의 상부와 결속된 일체로 분리될 수 있도록 하는 용기 개폐용 캡을 제공하는 것을 목적으로 한다.The present invention is to solve the above problem, by preventing a partial region of the fixing ring corresponding to the lower portion of the cap from being caught on the fixing jaw of the container entrance, the container so that the fixing ring can be integrally separated from the upper part of the cap. It is an object of the present invention to provide a cap for opening and closing.
또한, 본 발명은 사용자가 최초로 캡을 회전시켜 개방할 때 고정링에 형성된 절개선 또는 홀 형태의 변형유도부에 의하여 고정링의 원주가 증가됨으로써, 고정링이 용기 입구의 고정턱에 걸리지 않고 용이하게 분리될 수 있도록 하는 용기 개폐용 캡을 제공하는 것을 목적으로 한다.In addition, the present invention increases the circumference of the fixing ring by the incision line formed in the fixing ring or the deformation inducing part in the form of a hole when the user first rotates and opens the cap, so that the fixing ring does not get caught in the fixing jaw of the container entrance. It is an object of the present invention to provide a cap for opening and closing a container that can be separated.
또한, 본 발명은 절개선의 양 끝단에 수평 또는 곡선의 절개 모서리를 형성하거나, 원형의 절개선 홀을 구비함으로써, 사용자가 캡을 반복해서 개방하더라도 절개선 끝단에서 변형이 과도하게 진행되어 고정링이 파단되는 것을 방지할 수 있도록 하는 용기 개폐용 캡을 제공하는 것을 목적으로 한다.In addition, the present invention forms horizontal or curved incision edges at both ends of the incision line, or by providing a circular incision line hole, so that even if the user repeatedly opens the cap, the deformation proceeds excessively at the end of the incision line. It is an object of the present invention to provide a cap for opening and closing a container that can prevent the breakage.
또한, 본 발명은 틈이 협소한 절개선을 형성하거나, 변형유도부의 홀을 차폐하는 가림막을 형성함으로써, 고정링의 내부 공간으로 이물질, 세균 등이 침투되는 것을 방지하여 제품의 위생 상태를 보존할 수 있도록 하는 용기 개폐용 캡을 제공하는 것을 목적으로 한다.In addition, the present invention prevents foreign matter, bacteria, etc. from penetrating into the inner space of the fixing ring by forming an incision line with a narrow gap or shielding the hole in the deformation inducing part, thereby preserving the hygienic state of the product. It is an object of the present invention to provide a cap for opening and closing the container to be able to.
또한, 본 발명은 사용자가 캡을 회전시켜 개방할 때 고정링의 측면상에 상하방향으로 파단이 일어나도록 함으로써, 용기의 사용 후에 고정링을 용이하게 분리하여 배출할 수 있도록 하는 용기 개폐용 캡을 제공하는 것을 목적으로 한다.In addition, the present invention provides a container opening and closing cap that allows the user to easily separate and discharge the retaining ring after use by allowing the user to break up and down on the side of the retaining ring when the cap is opened by rotating the cap. It aims to provide.

That is, the deformable part 220 is formed in the shape of a bridge that mutually couples both ends in a side area of the fixing ring 200 similar to the connection tip 310 of the connection part 300 according to the present invention. I can. Like the hole-shaped deformed portion 220, the deformed portion 220 in the deformable tip shape may increase in length to the left and right by the applied stress, and accordingly, the circumferential length of the fixing ring 200 may also increase. have.
이러한 변형 팁 형태의 변형부(220)는 다양한 두께와 길이를 갖도록 형성될 수 있으며, 구체적인 형상 또한 두께가 일정한 심(sim) 형상, 얇은 두께의 필름 형상 등 다양할 수 있다.The deformable portion 220 in the form of such a deformable tip may be formed to have various thicknesses and lengths, and a specific shape may be various, such as a sim shape having a constant thickness, a thin film shape, and the like.
또한, 변형 팁 형태의 변형부(220)는 하나의 가닥으로 구성될 수도 있고, 복수의 가닥이 고정링(200)의 측면 양 끝단을 상호 결합시키도록 구성될 수도 있다. 한편, 변형부(220)의 세부적인 구성 및 기능에 관한 내용은 도 3을 참조하여 보다 상세하게 기술하기로 한다.In addition, the deformable portion 220 in the form of a deformable tip may be composed of one strand, or a plurality of strands may be configured to mutually couple both ends of the side surfaces of the fixing ring 200. Meanwhile, a detailed configuration and function of the deformable unit 220 will be described in more detail with reference to FIG. 3.
본 발명의 추가 실시예에 따르면, 변형부(220)는 고정링(200)의 측면에 복수로 구비될 수 있다. 이때 복수의 변형부(220)의 배치 관계(예를 들어, 변형부(220)의 개수 및 고정링(200)의 중심에 대한 각도 등)에 따라 증가되는 고정링(200)의 원주 길이가 상이할 수 있고, 이 또한 이하에서 자세히 후술하기로 한다.According to a further embodiment of the present invention, the deformable part 220 may be provided in plural on the side of the fixing ring 200. At this time, the circumferential length of the fixing ring 200 is different according to the arrangement relationship of the plurality of deformation parts 220 (for example, the number of deformation parts 220 and the angle with respect to the center of the fixing ring 200). It can be done, and this will also be described later in detail.
도 3은 본 발명의 일 실시예에 따라 변형부(220)에서 변형이 일어나기 전(a, c)과 변형이 일어난 후(b, d)의 상태를 나타낸 고정링(200)의 정면도이다.3 is a front view of the fixing ring 200 showing states before (a, c) and after (b, d) deformation occurs in the deformation unit 220 according to an embodiment of the present invention.
구체적으로, 도 3의 (a) 및 (b)는 사각형의 변형부(220)의 변형이 일어나기 전(a)과 변형이 일어난 후(b)의 상태를 나타낸 도면이고, 도 3의 (c) 및 (d)는 원형의 변형부(220)의 변형이 일어나기 전(c)과 변형이 일어난 후(d)의 상태를 나타낸 도면이다.Specifically, Figures 3 (a) and (b) are diagrams showing states before (a) and after (b) the deformation of the square-shaped deformed portion 220, and Figure 3 (c) And (d) is a view showing the state of the deformation of the circular deformed portion 220 before (c) and after the deformation (d).
먼저, 도 3의 (a)를 참조하여 변형부(220)의 세부적인 구성에 관해 설명하기로 한다.First, a detailed configuration of the deformation unit 220 will be described with reference to FIG. 3A.
도 3의 (a)에 도시된 바와 같이, 본 발명의 일 실시예에 따른 변형부(220)는, 고정링(200)의 측면 중 적어도 일부 영역을 관통하는 홀(hole) 형태로 구비되는 변형유도부(221), 변형유도부(221)의 상부에 구비되어 작용하는 응력에 의해 소성변형이 일어나는 제1 소성변형부(222) 및 변형유도부(221)의 하부에 구비되어 작용하는 응력에 의해 소성변형이 일어나는 제2 소성변형부(223)로 구성될 수 있다.As shown in (a) of Figure 3, the deformation portion 220 according to an embodiment of the present invention is provided in the form of a hole penetrating at least a partial area of the side surface of the fixing ring 200 The first plastic deformation part 222, which is provided on the upper part of the induction part 221 and the deformation induction part 221 to cause plastic deformation, and the lower part of the deformation induction part 221, and plastic deformation by the applied stress It may be composed of a second plastic deformation portion 223 occurs.
변형유도부(221)는 고정링(200)의 측면 중 일부 영역을 관통하는 홀 형태로 구비될 수 있고, 홀의 구체적인 형상에 따라 제1 소성변형부(222) 및 제2 소성변형부(223)의 길이, 두께 등이 결정될 수 있다. 즉, 고정링(200)의 측면에서 변형유도부(221)의 상부에 띠 형상으로 잔존하는 부분이 제1 소성변형부(222), 변형유도부(221)의 하부에 띠 형상으로 잔존하는 부분이 제2 소성변형부(223)로 정의되므로, 변형유도부(221)가 차지하는 영역에 따라 제1 소성변형부(222) 및 제2 소성변형부(223)가 차지하는 영역도 또한 결정될 수 있다.The deformation inducing part 221 may be provided in the form of a hole penetrating through some of the side surfaces of the fixing ring 200, and according to the specific shape of the hole, the first plastic deformation part 222 and the second plastic deformation part 223 Length, thickness, etc. can be determined. That is, from the side of the fixing ring 200, a portion remaining in a strip shape above the deformation inducing portion 221 is the first plastic deformation portion 222, and a portion remaining in a strip shape below the deformation inducing portion 221 is controlled. 2 Since it is defined as the plastic deformation part 223, the area occupied by the first plastic deformation part 222 and the second plastic deformation part 223 may also be determined according to the area occupied by the deformation inducing part 221.
예를 들어, 변형유도부(221)는 사각형의 홀 형태로 구비될 수 있다. 이에 따라 제1 소성변형부(222) 및 제2 소성변형부(223)는 변형부(220)의 영역에서 각각 일정한 두께를 갖도록 형성될 수 있다. 이러한 변형부(220)의 구성이 도 3의 (a)에 예시적으로 도시된다.For example, the deformation inducing part 221 may be provided in the shape of a square hole. Accordingly, the first plastic deformation portion 222 and the second plastic deformation portion 223 may be formed to have a predetermined thickness in the region of the deformation portion 220, respectively. The configuration of such a deformable part 220 is exemplarily shown in FIG. 3A.
먼저, 제1 소성변형부(222)는 변형유도부(221)의 사각형 윗변 길이와 동일한 길이를 가지면서, 길이 방향에 걸쳐 두께가 일정하도록 형성될 수 있다.First, the first plastic deformation portion 222 may have a length equal to the length of the upper side of the square of the deformation inducing portion 221 and may be formed to have a constant thickness over the length direction.
두께가 일정하면 작용하는 응력에 의해 변형이 일어나는 비율도 모든 지점에서 일정할 수 있고, 따라서 각각의 지점에 힘이 고르게 분산됨으로써 제1 소성변형부(222)에서 파단이 일어날 확률이 보다 낮아질 수 있다.If the thickness is constant, the rate at which deformation occurs due to the applied stress may be constant at all points, and thus, the probability of fracture occurring in the first plastic deformation portion 222 may be lowered by evenly distributing the force at each point. .
이와 마찬가지로 제2 소성변형부(223)의 경우에도 길이 방향에 걸쳐 두께가 일정하도록 형성됨으로써, 제2 소성변형부(223)에서 파단이 일어날 확률이 보다 낮아질 수 있다. 즉, 변형유도부(221)가 사각형의 홀 형태로 구비됨으로써, 제1 소성변형부(222) 및 제2 소성변형부(223)의 안정성이 증대될 수 있다.Likewise, in the case of the second plastically deformed portion 223 as well, the thickness is formed to be constant over the length direction, so that the probability of fracture in the second plastically deformed portion 223 may be lowered. That is, since the deformation inducing part 221 is provided in a rectangular hole shape, stability of the first plastic deformation part 222 and the second plastic deformation part 223 may be increased.
본 발명의 일 실시예에 따른 제1 소성변형부(222) 및 제2 소성변형부(223)는, 용기 개폐용 캡(10)이 회전하면서 용기의 상부에 형성된 나사산을 따라 상승할 때 각각 인장에 따른 응력을 받고, 그에 따라 제1 소성변형부(222) 및 제2 소성변형부(223) 각각은 소성변형되어 길이가 증가될 수 있다.The first plastic deformation portion 222 and the second plastic deformation portion 223 according to an embodiment of the present invention are each tensioned when the container opening and closing cap 10 rotates and ascends along the thread formed on the top of the container. The first plastic deformation portion 222 and the second plastic deformation portion 223 may be plastically deformed to increase the length of each of the first plastic deformation portions 222 and 223 according to the stress.
이렇게 소성변형에 따라 길이가 증가되는 제1 소성변형부(222) 및 제2 소성변형부(223)의 구성은 도 3의 (b)에 예시적으로 도시된다.The configuration of the first plastic deformation portion 222 and the second plastic deformation portion 223 whose length increases according to the plastic deformation is illustrated in FIG. 3B by way of example.
도 3의 (b)에 도시된 바와 같이, 제1 소성변형부(222) 및 제2 소성변형부(223)가 각각 인장에 따른 응력을 받으면, 그 두께가 얇아지면서 길이가 증가될 수 있다.As shown in (b) of FIG. 3, when each of the first plastic deformation portion 222 and the second plastic deformation portion 223 receives a stress according to tension, the thickness thereof may decrease and the length may increase.
여기서, 소성변형이란 탄성변형과 구별되는 개념으로 볼 수 있다. 즉, 탄성변형은 물체에 힘을 가했을 때 형태의 변형이 일어났다가, 힘이 제거되면 다시 원래의 형태로 복귀하는 것을 의미한다. 이에 반해, 소성변형은 물체에 힘을 가했을 때 형태의 변형이 일어나고, 힘이 제거되더라도 변형된 형태를 유지하는 영구변형의 의미를 가진다.Here, plastic deformation can be seen as a concept distinguished from elastic deformation. In other words, elastic deformation means that the shape deformation occurs when a force is applied to an object, and then returns to the original shape when the force is removed. On the other hand, plastic deformation has a meaning of permanent deformation that transforms the shape when a force is applied to an object, and maintains the deformed shape even if the force is removed.
본 발명의 일 실시예에 따른 제1 소성변형부(222) 및 제2 소성변형부(223)는 인장에 따른 응력을 받으면 소성변형이 일어나므로, 힘이 제거된 이후에도 두께가 얇아지고 길이가 증가된 상태를 유지할 수 있다.The first plastic deformation portion 222 and the second plastic deformation portion 223 according to an embodiment of the present invention undergo plastic deformation when subjected to a stress due to tension, so that the thickness becomes thinner and the length increases even after the force is removed. You can keep it.
이에 따라, 사용자가 최초로 용기를 개방하기 위해 용기 개폐용 캡(10)을 회전시키면 변형부(220)에도 응력이 작용하고, 이때 제1 소성변형부(222) 및 제2 소성변형부(223)가 각각 응력에 의해 길이가 증가된 이후에는 다시 원래의 두께 및 길이로 복귀하지 않을 수 있다. 즉, 사용자가 최초로 용기 개폐용 캡(10)을 회전시킨 이후에는, 본 발명의 일 실시예에 따른 고정링(200)의 원주가 증가된 상태를 유지할 수 있다.Accordingly, when the user rotates the container opening/closing cap 10 to open the container for the first time, stress is also applied to the deformation part 220, and at this time, the first plastic deformation part 222 and the second plastic deformation part 223 May not return to the original thickness and length again after the length is increased by each stress. That is, after the user first rotates the container opening and closing cap 10, the circumference of the fixing ring 200 according to an embodiment of the present invention can be maintained in an increased state.
따라서 본 발명의 일 실시예에 따른 변형부(220)에 탄성변형이 아닌 소성변형이 일어남으로써, 용기 개폐용 캡(10)이 한번 개방된 이후에는, 걸림턱(210)과 고정턱 간의 작용에도 불구하고 고정링(200)이 용이하게 용기 바디에 결합 또는 분리될 수 있게 된다.Therefore, as plastic deformation, not elastic deformation, occurs in the deformation part 220 according to an embodiment of the present invention, after the container opening and closing cap 10 is opened once, the action between the locking jaw 210 and the fixed jaw Nevertheless, the fixing ring 200 can be easily coupled or separated from the container body.
또한, 제1 소성변형부(222) 및 제2 소성변형부(223)는 소성변형이 일어나 그 두께가 얇아지더라도 파단되지 않을 수 있다. 구체적으로 용기 개폐용 캡(10)에 인장에 따른 응력이 작용하면, 제1 소성변형부(222) 및 제2 소성변형부(223)를 구성하는 고분자 사슬들은 변형 전보다 얇고 긴 형태의 중합체(polymer) 구조를 형성하도록 이동 및 재배열될 수 있다. 이러한 고분자 사슬들의 재배열이 일어나는 소성변형 과정을 '넥변형(necking)'이라고 한다.In addition, the first plastic deformation portion 222 and the second plastic deformation portion 223 may not be fractured even if plastic deformation occurs and the thickness thereof is reduced. Specifically, when a stress due to tension acts on the container opening and closing cap 10, the polymer chains constituting the first plastic deformation part 222 and the second plastic deformation part 223 are thinner and longer than before the deformation. ) Can be moved and rearranged to form a structure. The plastic deformation process in which the rearrangement of these polymer chains occurs is called'necking'.
그리고 넥변형이 일어난 고분자 사슬들에는 '결정화(crystallization)'가 유도되어 해당 중합체 구조의 강도가 증가될 수 있다. 결정화는 고분자 사슬들이 일정한 방향으로 배열되어 규칙적인 구조를 형성하는 과정을 의미한다.In addition,'crystallization' is induced in the polymer chains in which the neck deformation has occurred, so that the strength of the corresponding polymer structure may be increased. Crystallization refers to a process in which polymer chains are arranged in a certain direction to form a regular structure.
정리하면, 변형부(220)에서 가장 얇은 부분인 제1 소성변형부(222) 및 제2 소성변형부(223)에 응력이 집중되어 넥변형이 일어나고, 이후 결정화에 의해 강도가 증가된 각각의 소성변형부는 얇아진 두께에도 불구하고 파단되지 않은 상태를 유지할 수 있게 된다.In summary, the stress is concentrated in the first plastic deformation portion 222 and the second plastic deformation portion 223, which are the thinnest portions of the deformation portion 220, resulting in neck deformation, and each of which strength is increased by crystallization. The plastic deformation portion can be maintained in an unbroken state despite the thinner thickness.
추가로, 고정링(200)의 원주가 증가되면 본 발명의 일 실시예에 따른 연결부(300)의 복수의 연결 팁(310) 중 적어도 일부는 파단되지 않을 수 있다. 즉, 연결 팁(310)이 파단되는 것은 고정턱에 걸리는 걸림턱(210)의 작용에 의한 것이므로, 고정링(200)의 원주 증가로 고정턱에 걸리는 영역이 감소하면 파단되는 연결 팁(310)의 개수도 감소할 수 있다.In addition, when the circumference of the fixing ring 200 is increased, at least some of the plurality of connection tips 310 of the connection part 300 according to an embodiment of the present invention may not be broken. That is, the connection tip 310 is broken due to the action of the locking jaw 210 applied to the fixed jaw, so the connection tip 310 that is broken when the area applied to the fixed jaw decreases due to an increase in the circumference of the fixing ring 200 The number of can also be reduced.
그에 따라, 연결부(300)를 구성하는 복수의 연결 팁(310) 중 적어도 하나가 파단되지 않고 결합을 유지하게 되고, 본체(100) 및 고정링(200)은 결속된 일체로서의 상태를 유지하면서 용기 바디로부터 분리될 수 있게 된다. 즉, 사용자가 최초로 용기 개폐용 캡(10)을 회전시킨 이후에는 연결 팁(310)이 더이상 파단되지 않을 수 있고, 그 이후부터 본체(100) 및 고정링(200)이 결속된 일체로서 용기 바디와 결합 또는 분리될 수 있다. Accordingly, at least one of the plurality of connection tips 310 constituting the connection part 300 is not broken and maintains the connection, and the main body 100 and the fixing ring 200 maintains the state as a united unit while maintaining the container It can be separated from the body. That is, after the user rotates the container opening and closing cap 10 for the first time, the connection tip 310 may no longer be broken, and after that, the body 100 and the fixing ring 200 are bound together as an integral part of the container body. Can be combined with or separated from.

도 3의 (c)에 도시된 바와 같이, 원형의 홀 형태를 갖는 변형유도부(221)의 상부 및 하부에도 각각 제1 소성변형부(222) 및 제2 소성변형부(223)가 구비된다. 또한 전술한 것과 마찬가지로, 제1 소성변형부(222) 및 제2 소성변형부(223)가 인장에 따른 응력을 받으면 그 두께가 얇아지고 길이가 증가된 상태를 유지할 수 있다. 이와 같이 소성변형이 일어난 원형의 변형부(220)의 구성은 도 3의 (d)에 예시적으로 도시된다.As shown in (c) of FIG. 3, a first plastic deformation portion 222 and a second plastic deformation portion 223 are also provided in the upper and lower portions of the deformation inducing portion 221 having a circular hole shape, respectively. In addition, as described above, when the first plastic deformation portion 222 and the second plastic deformation portion 223 are subjected to a stress due to tension, the thickness thereof is reduced and the length thereof can be maintained in an increased state. The configuration of the circular deformation portion 220 in which plastic deformation has occurred is illustrated in FIG. 3D by way of example.
한편 도면에는 도시되지 않았지만, 본 발명의 일 실시예에 따른 변형유도부(221)는 타원형, 마름모형, 다각형 등의 형태로 구비될 수도 있다. 즉, 변형유도부(221)의 구체적인 형태는 더욱 다양할 수 있고, 도 3의 (a) 내지 (d)에 도시된 사각형 또는 원형의 변형유도부(221)는 예시적인 것에 불과하다.On the other hand, although not shown in the drawings, the deformation inducing unit 221 according to an embodiment of the present invention may be provided in the form of an ellipse, a rhombus, a polygon, or the like. That is, the specific shape of the deformation induction part 221 may be more diverse, and the square or circular deformation induction part 221 shown in FIGS. 3A to 3D is merely exemplary.
참고로, 본 발명의 다른 실시예에 따른 용기 개폐용 캡(10)은, 작용하는 응력에 의한 제1 소성변형부(222)의 길이 증가가, 작용하는 응력에 의한 제2 소성변형부(223)의 길이 증가와 상이할 수도 있다.For reference, in the container opening and closing cap 10 according to another embodiment of the present invention, an increase in the length of the first plastic deformation portion 222 due to the applied stress, the second plastic deformation portion 223 due to the applied stress It may be different from the increase in length of ).
구체적으로, 용기 개폐용 캡(10)은 다양한 형상을 가질 수 있고, 이에 따라 변형부(220)의 형성 위치, 구체적인 형상 등도 다양하게 구현될 수 있다.Specifically, the container opening/closing cap 10 may have various shapes, and accordingly, the formation position of the deformable part 220 and a specific shape may be variously implemented.
먼저 도 3에 도시된 것과 같이, 용기 개폐용 캡(10)의 측면이 지면과 항상 일정한 각도를 이루도록 형성되고, 변형부(220)가 고정링(200)의 측면에서 정확하게 대칭을 이루도록 형성될 수 있다. 이러한 경우에는, 용기 개폐용 캡(10)의 개방 시에 작용하는 응력에 의한 제1 소성변형부(222) 및 제2 소성변형부(223)의 길이 증가의 양이 동일할 수도 있다.First, as shown in Fig. 3, the side of the container opening and closing cap 10 is formed to always form a certain angle with the ground, and the deformation portion 220 can be formed to be accurately symmetrical from the side of the fixing ring 200. have. In this case, the amount of increase in length of the first plastic deformation portion 222 and the second plastic deformation portion 223 due to a stress acting upon opening of the container opening and closing cap 10 may be the same.
이에 반해 도면에는 명확하게 도시되지 않았지만, 용기 개폐용 캡(10)의 측면이 경사를 갖도록 형성될 수 있고, 이때 변형부(220)의 형성 위치 및 구체적인 형태도 용기 개폐용 캡(10)의 형상에 따라 조정될 수 있다. 즉, 제1 소성변형부(222)와 제2 소성변형부(223)가 대칭을 형성하지 않을 수 있고, 이에 따라 제1 소성변형부(222)와 제2 소성변형부(223)의 두께 및 응력에 의한 길이 변화가 서로 상이할 수 있다.On the other hand, although not clearly shown in the drawings, the side of the container opening and closing cap 10 may be formed to have an inclination, and at this time, the formation position and specific shape of the deformation part 220 are also the shape of the container opening and closing cap 10 Can be adjusted according to. That is, the first plastic deformation portion 222 and the second plastic deformation portion 223 may not form a symmetry, and accordingly, the thickness of the first plastic deformation portion 222 and the second plastic deformation portion 223 The length change due to stress may be different from each other.
한편, 전술한 바와 같이 본 발명의 추가 실시예에 따르면 변형부(220)는 복수로 구비될 수 있고, 구비되는 변형부(220)의 개수 및 배치 관계에 따라 변형이 일어나는 정도가 상이할 수 있다. 즉, 변형부(220)의 소성변형으로 인하여 증가되는 길이가 상이할 수 있고, 이에 따라 본 발명에 따른 용기 개폐용 캡(10)의 복수의 연결 팁(310) 중 파단되는 연결 팁(310)의 비율도 상이할 수 있다.Meanwhile, as described above, according to an additional embodiment of the present invention, a plurality of deformation units 220 may be provided, and the degree of deformation may be different depending on the number and arrangement relationship of the deformation units 220 provided. .

[표 1]의 실험결과는 하나 또는 복수의 변형부(220)에서 소성변형이 일어났을 때 각각의 변형부(220)가 증가된 길이를 나타낸다. 참고로, 본 발명의 발명자가 실험에서 사용한 고정링(200)은 외부 원주 길이가 98mm, 변형 전의 변형부(220)의 길이가 2.2mm에 해당하는 것이다.The experimental results in [Table 1] indicate the length of each deformed portion 220 increased when plastic deformation occurred in one or more deformed portions 220. For reference, the fixed ring 200 used in the experiment by the inventor of the present invention has an outer circumference of 98 mm and a length of the deformed portion 220 before deformation is 2.2 mm.
또한, [표 1]에 기재된 '연결부 유지(파단)'은 최초로 용기 개폐용 캡(10)이 개방되었을 때 파단되지 않고 유지된 연결 팁의 개수 및 파단된 연결 팁의 개수를 나타낸 것이다. 즉, 실험 대상이 되는 용기 개폐용 캡(10)의 연결부(300)는 최초에 각각 12개의 연결 팁(310)을 포함하고 있었으며, [표 1]에 나타난 바와 같이 변형부(220)의 증가된 길이에 따라 서로 상이한 개수의 연결 팁(310)이 파단되었다. In addition, the'connection part maintenance (breaking)' described in [Table 1] indicates the number of connection tips maintained without breaking when the container opening and closing cap 10 is opened for the first time and the number of broken connection tips. That is, the connection part 300 of the container opening and closing cap 10 to be tested initially included 12 connection tips 310, respectively, and as shown in [Table 1], the increased amount of the deformation part 220 A different number of connection tips 310 were broken depending on the length.
[표 1]에 나타난 바와 같이, 변형부(220)의 개수 및 배치(즉 각도)에 따라 각각의 변형부(220)가 증가되는 길이가 서로 상이함을 알 수 있다. 특히, 고정링(200)이 2개의 변형부(220)를 포함하면서, 양 변형부(220) 간에 서로 180도의 각도를 이루도록 할 때 전체 길이가 가장 크게 증가되었음을 확인할 수 있다.As shown in [Table 1], it can be seen that the lengths at which the respective deformable portions 220 are increased according to the number and arrangement (ie, angle) of the deformable portions 220 are different from each other. In particular, it can be seen that when the fixing ring 200 includes two deformable parts 220 and forms an angle of 180 degrees between both deformable parts 220, the total length is increased the most.
도 4는 본 발명의 일 실시예에 따라 변형부(220)가 고정링(200)의 측면에 절개선(250)으로 구비되는 용기 개폐용 캡(10)의 사시도이다.4 is a perspective view of the container opening and closing cap 10 in which the deformable part 220 is provided as a cut line 250 on the side of the fixing ring 200 according to an embodiment of the present invention.
발명의 일 실시예에 따른 용기 개폐용 캡(10)은 고정링(200)의 측면 적어도 일 영역에 세로 방향으로 형성되되, 작용하는 응력에 의해 변형되어 고정링(200)의 원주를 증가시키도록 구성되는 절개선(250)을 포함할 수 있다. 여기서, 절개선(250)의 구체적인 형태는 도 5에 자세히 도시되어 있으므로, 이를 함께 참조하기로 한다.The container opening and closing cap 10 according to an embodiment of the present invention is formed in a vertical direction on at least one area of the side of the fixing ring 200, and is deformed by the applied stress to increase the circumference of the fixing ring 200. It may include a cut line 250 to be configured. Here, since the specific shape of the cut line 250 is shown in detail in FIG. 5, this will be referred to together.
도 5는 본 발명의 일 실시예에 따라 다양한 형태의 절개선(250)이 형성된 고정링(200)의 정면도를 각각 나타낸 것이다.5 is a front view of a fixing ring 200 in which various types of cut lines 250 are formed according to an embodiment of the present invention.
도 4 및 도 5에 도시되는 바와 같이, 본 발명의 일 실시예에 따른 절개선(250)은 고정링(200)의 측면에 세로 방향의 협소한 틈을 갖도록 구비될 수 있다. 사용자가 최초로 용기를 개방하기 위해 용기 개폐용 캡(10)을 회전시키면, 용기 개폐용 캡(10)은 나사산을 따라 회전하면서 조금씩 상승할 수 있다. 또한, 용기 개폐용 캡(10)이 상승함에 따라, 고정턱에 걸려 이동이 제한되는 고정링(200)의 걸림턱(210)에는 응력이 작용할 수 있다. 절개선(250)은 작용하는 응력에 의해 비틀리면서 그 상부 및 하부 끝단의 변형을 유도하며, 이에 따라 고정링(200)의 원주 길이가 증가할 수 있다. 여기서 고정링(200)은, 절개선(250)을 둘러싸도록 형성되되, 작용하는 응력에 의해 변형되어 고정링(200)의 원주를 증가시키도록 구성되는 변형부(220)를 포함할 수 있다. 즉, 도 5에 도시된 바와 같이 절개선(250)이 비틀 림에 따라 변형이 일어나 길이가 증가되는 부분은 변형부(220)에 해당한다.As shown in FIGS. 4 and 5, the incision line 250 according to an embodiment of the present invention may be provided to have a narrow gap in the vertical direction on the side of the fixing ring 200. When the user first rotates the container opening and closing cap 10 to open the container, the container opening and closing cap 10 may rise little by little while rotating along the screw thread. In addition, as the container opening and closing cap 10 rises, a stress may be applied to the locking jaw 210 of the fixing ring 200, which is caught by the fixing jaw and restricts movement. The incision line 250 is twisted by the applied stress and induces deformation of its upper and lower ends, and thus the circumferential length of the fixing ring 200 may increase. Here, the fixing ring 200 may include a deformable part 220 formed to surround the incision line 250 and configured to increase the circumference of the fixing ring 200 by being deformed by the applied stress. That is, as shown in FIG. 5, a portion in which the incision line 250 is deformed according to the twist and thus the length is increased corresponds to the deformed portion 220.
이때 도 5의 (a) 내지 (c)에 도시되는 바와 같이 절개선(250)이 형성된 부분을 확대하여 보면, 절개선(250)은 기둥 형태의 가로 폭이 좁은 틈을 가질 수 있다.At this time, as shown in FIGS. 5A to 5C, when the incision line 250 is formed enlarged, the incision line 250 may have a gap having a narrow horizontal width in the form of a column.
보다 구체적으로, 절개선(250)은 도 5의 (a)와 같이 절개선(250)의 양 끝단이 각각 수평의 절개 모서리(251)를 갖도록 형성될 수 있다. 즉, 절개선(250)을 구성하는 틈이 세로로 긴 직사각형의 형태를 가질 수 있다. 또한, 절개선(250)은 도 5의 (b)와 같이 절개선(250)의 양 끝단이 각각 외측으로 볼록한 곡선의 절개 모서리(251)를 갖도록 형성될 수 있고, 도 5의 (c)와 같이 곡선의 절개 모서리(251)가 절개선(250)의 가로 폭보다 넓은 폭을 갖도록 돌출 형성될 수도 있다.More specifically, the cut line 250 may be formed so that both ends of the cut line 250 have horizontal cut edges 251 as shown in FIG. 5A. That is, the gap constituting the cut line 250 may have a vertically long rectangular shape. In addition, the incision line 250 may be formed so that both ends of the incision line 250 have a curved incision edge 251 that is convex outwardly, as shown in FIG. 5 (b), and Likewise, the curved cut edge 251 may be formed to protrude to have a width wider than the horizontal width of the cut line 250.
절개선(250)에 응력이 작용하게 되면, 절개선(250)의 상부 및 하부에 구비되는 각각의 절개 모서리(251)가 서로 상이한 방향의 힘을 받게 되고, 이에 따라 절개 모서리(251)는 가로 방향으로 비틀려 인장되는 변형을 일으킬 수 있다. 그리고 절개 모서리(251)가 비틀려 인장되면 변형부(220)에도 가로 방향으로 변형이 일어나 고정링(200)의 원주 길이가 적어도 일부 길이만큼 증가할 수 있다.When a stress is applied to the incision line 250, each incision edge 251 provided at the top and bottom of the incision line 250 receives forces in different directions, and accordingly, the incision edge 251 is horizontally It can be twisted in the direction and cause a strain that is tensioned. In addition, when the incision edge 251 is twisted and stretched, the deformation portion 220 is also deformed in the horizontal direction, so that the circumferential length of the fixing ring 200 may increase by at least a portion of the length.
여기서, 변형부(220)는 고정링(200)의 측면 적어도 일부 영역에서 적어도 일 면이 고정링(200)의 다른 영역보다 더 얇은 두께를 갖도록 형성될 수도 있으며, 절개선(250)은 변형부(220)의 중앙에 위치할 수 있다.Here, the deformable part 220 may be formed so that at least one side of the fixing ring 200 has a thinner thickness than the other regions of the fixing ring 200 in at least a portion of the side surface, and the cut line 250 is a deformable part It can be located in the center of 220.
참고로, 도 5의 (a) 내지 (c)에 도시되는 바와 같은 수평 또는 곡선의 절개 모서리(251)를 갖는 절개선(250)은, 반복적으로 응력이 작용하더라도 과도하게 변형이 일어나지 않을 수 있다. 즉, 수평 또는 곡선의 절개 모서리(251)는 절개선(250)의 양 끝단이 가로 방향으로 인장되는 것을 유도할 뿐이고, 세로 방향으로 틈이 계속 벌어져 고정링(200)이 파단되는 것은 방지할 수 있다.For reference, the cutting line 250 having a horizontal or curved cutting edge 251 as shown in FIGS. 5A to 5C may not be excessively deformed even if stress is repeatedly applied. . That is, the horizontal or curved incision edge 251 only induces both ends of the incision line 250 to be stretched in the horizontal direction, and it is possible to prevent the fixing ring 200 from being broken due to the continuous opening of the gap in the vertical direction. have.
한편, 도 5에 도시되는 절개선(250) 및 절개 모서리(251)의 형태는 예시적인 것에 불과하며, 고정링(200)의 파단을 방지할 수 있는 한 보다 다양한 형태로 형성될 수 있다.Meanwhile, the shapes of the incision line 250 and the incision edge 251 shown in FIG. 5 are only exemplary, and may be formed in more various shapes as long as it can prevent the breakage of the fixing ring 200.
본 발명의 다른 실시예에 따르면, 도 5의 (d)에 도시되는 바와 같이 절개선(250)의 양 끝단에 각각 원형의 절개선 홀(252)이 형성될 수 있다. 원형의 절개선 홀(252)은 전술한 수평 또는 곡선의 절개 모서리(251)가 형성되는 경우와 마찬가지로, 절개선(250)의 과도한 변형을 방지할 수 있다. 즉, 절개선 홀(252)이 형성되는 위치 및 크기가 필요에 따라 조절되어 제조됨으로써, 용기 개폐용 캡(10)의 반복적인 개방에 의하더라도 고정링(200)이 파단되지 않도록 그 변형의 정도가 조절될 수 있다.According to another embodiment of the present invention, circular cutting line holes 252 may be formed at both ends of the cutting line 250 as shown in (d) of FIG. 5. The circular cut line hole 252 may prevent excessive deformation of the cut line 250 as in the case where the horizontal or curved cut edge 251 is formed. That is, the position and size at which the cut-out hole 252 is formed are adjusted and manufactured as necessary, so that the fixing ring 200 is not broken even when the container opening and closing cap 10 is repeatedly opened. Can be adjusted.
한편, 도 5의 (d)에 도시되는 절개선 홀(252)의 위치 및 크기는 예시적인 것에 불과하며, 고정링(200)의 파단을 방지할 수 있는 한 보다 다양한 위치 및 크기로 형성될 수 있다.On the other hand, the position and size of the incision line hole 252 shown in (d) of FIG. 5 are only exemplary, and may be formed in more various positions and sizes as long as it can prevent the breakage of the fixing ring 200. have.
추가적으로, 고정링(200)에는 절개선(250)이 복수로 구비될 수도 있다. 그리고 복수의 절개선(250)이 고정링(200)의 중심에 대하여 이루는 각도는 다양할 수 있다. 예를 들어, 고정링(200)에 2개의 절개선(250)이 구비되는 경우에 양 절개선(250)은 120°, 150°, 180° 등의 각도를 이루도록 배치될 수 있다.Additionally, a plurality of cutting lines 250 may be provided in the fixing ring 200. In addition, an angle formed by the plurality of incision lines 250 with respect to the center of the fixing ring 200 may vary. For example, when two cut lines 250 are provided on the fixing ring 200, both cut lines 250 may be disposed to form an angle such as 120°, 150°, 180°, and the like.
전술한 바와 같이 절개선(250)의 개수, 각도 및 절개 모서리(251)의 형태를 상이하게 하여 고정링(200)을 제작할 수 있고, 각각의 요인에 따라 절개선(250)을 둘러싸는 변형부(220)의 변형되는 정도가 달라질 수 있다. 참고로, 본 발명의 발명자는 절개선(250)의 개수, 각도 및 절개 모서리(251)의 형태를 상이하게 하여 용기 개폐용 캡(10)을 개방하는 실험을 수행하였고, 그 결과는 하기의 [표 2]와 같다.As described above, the number, angle, and shape of the cut edge 251 may be different to manufacture the fixing ring 200, and a deformation portion surrounding the cut line 250 according to each factor The degree of deformation of (220) may vary. For reference, the inventor of the present invention performed an experiment of opening the container opening and closing cap 10 by making the number, angle, and shape of the cut edge 251 different from the cut line 250, and the results are as follows.

[표 2]에 기재된 '연결 팁 파단(잔존)'은 최초로 용기 개폐용 캡(10)이 개방되었을 때 파단된 연결 팁의 개수 및 파단되지 않고 잔존한 연결 팁의 개수를 나타낸 것이다. 즉, 실험 대상이 되는 용기 개폐용 캡(10)의 연결부(300)는 최초에 각각 12개의 연결 팁(310)을 포함하고 있었으며, [표 2]에 나타난 바와 같이 절개선(250)의 유무와 개수, 2개의 절개선(250)이 이루는 각도, 절개 모서리(251)의 형태에 따라 서로 상이한 개수의 연결 팁(310)이 파단되었다.The'connection tip fracture (remaining)' described in [Table 2] indicates the number of connection tips that are broken when the container opening and closing cap 10 is opened for the first time and the number of connection tips that remain without being broken. That is, the connection part 300 of the container opening/closing cap 10 to be tested initially included 12 connection tips 310, respectively, and the presence or absence of the incision line 250 as shown in [Table 2] According to the number, the angle formed by the two incision lines 250, and the shape of the incision edge 251, a different number of connection tips 310 were broken.
또한, 각각의 요인에 따라 절개선(250)을 둘러싸는 변형부(220)의 길이가 소성변형으로 증가되는 정도가 서로 상이함을 알 수 있다. 즉, 변형부(220)의 길이가 증가함에 따라 최초에 구비되어 있던 12개의 연결 팁(310) 중에서 일부가 파단되지 않을 수 있고, 연결 팁(310) 중에서 일부가 잔존함으로써 고정링(200)이 본체(100)와 함께 일체로써 용기 바디로부터 취출될 수 있다.In addition, it can be seen that depending on each factor, the length of the deformation portion 220 surrounding the incision line 250 is increased by plastic deformation. That is, as the length of the deformable part 220 increases, some of the 12 connection tips 310 initially provided may not be broken, and some of the connection tips 310 remain, so that the fixing ring 200 It can be taken out from the container body as an integral part with the body 100.
작용하는 응력에 의해 고정링(200)의 원주를 증가시킴으로써, 용기 바디에 형성된 고정턱에 걸림턱(210)이 걸리지 않도록 하는 수단에는 변형유도부(221) 및 가림막(260)이 포함될 수 있다. 변형유도부(221) 및 가림막(260)이 고정링(200)에 구비되는 형태는 도 6에 도시되므로, 이를 참조하여 설명하기로 한다.By increasing the circumference of the fixing ring 200 by the applied stress, the means for preventing the locking jaw 210 from being caught on the fixing jaw formed in the container body may include a deformation inducing portion 221 and a covering film 260. A form in which the deformation inducing part 221 and the shielding film 260 are provided on the fixing ring 200 is shown in FIG. 6, and will be described with reference to this.
도 6의 (a)는 본 발명의 일 실시예에 따라 가림막(260)이 형성된 고정링(200)의 정면도이고, 도 6의 (b)는 본 발명의 일 실시예에 따라 가림막(260) 및 절개선(250)이 함께 형성된 고정링(200)의 정면도이다.6A is a front view of the fixing ring 200 on which the shielding film 260 is formed according to an embodiment of the present invention, and FIG. 6B is a shielding film 260 and It is a front view of the fixing ring 200 in which the cut line 250 is formed together.
도 6의 (a)를 참조하면, 고정링(200)에는 변형유도부(221) 및 변형유도부(221)를 차폐하는 가림막(260)이 형성될 수 있다. 본 발명의 일 실시예에 따른 변형유도부(221)는 고정링(200)의 측면 중 적어도 일부를 관통하도록 홀(hole)의 형태로 구비될 수 있다.Referring to FIG. 6A, a strain inducing portion 221 and a covering layer 260 shielding the strain inducing portion 221 may be formed on the fixing ring 200. The deformation inducing part 221 according to an embodiment of the present invention may be provided in the form of a hole so as to penetrate at least a part of the side surface of the fixing ring 200.
한편, 도면에는 하나의 변형유도부(221)가 형성된 상태만이 도시되어 있으나, 변형유도부(221)는 고정링(200)의 측면에 복수로 구비될 수도 있다. 이 때 복수의 변형유도부(221)의 배치 관계(예를 들어, 변형유도부(221)의 개수 및 고정링(200)의 중심에 대한 각도 등)에 따라 증가되는 고정링(200)의 원주 길이는 상이할 수 있다.On the other hand, although only a state in which one deformation inducing part 221 is formed is shown in the drawing, a plurality of deformation inducing parts 221 may be provided on the side of the fixing ring 200. At this time, the circumferential length of the fixing ring 200, which is increased according to the arrangement relationship of the plurality of deformation inducing parts 221 (for example, the number of deformation inducing parts 221 and the angle with respect to the center of the fixing ring 200), is It can be different.
또한, 도면에는 변형유도부(221)가 원형으로 형성되는 것만을 예시하였으나, 본 발명의 일 실시예에 따른 변형유도부(221)는 사각형, 타원형, 마름모형, 다각형 등의 형태로 구비될 수도 있다. 즉, 변형유도부(221)의 구체적인 형태는 다양할 수 있다.Further, in the drawings, only the deformation induction part 221 is formed in a circular shape, but the deformation induction part 221 according to an embodiment of the present invention may be provided in the form of a square, an ellipse, a rhombus, a polygon, or the like. That is, the specific shape of the deformation inducing part 221 may be various.
본 발명의 일 실시예에 따른 가림막(260)은, 도 6의 (a)에 도시되는 바와 같이 변형유도부(221)의 홀을 차폐하도록 구성될 수 있다. 여기서, 가림막(260)의 구체적인 형태는 변형유도부(221)의 형태에 의하여 원형, 사각형, 타원형 등으로 달라질 수 있으며, 가림막(260)의 두께는 필요에 따라 다양하게 조절될 수 있다.The shielding film 260 according to an embodiment of the present invention may be configured to shield the hole of the deformation inducing part 221 as shown in FIG. 6A. Here, the specific shape of the shielding film 260 may be changed into a circle, a square, an oval, etc. depending on the shape of the deformation inducing part 221, and the thickness of the shielding film 260 may be variously adjusted as necessary.
이와 같이 본 발명의 일 실시예에 따라 가림막(260)의 구성이 추가됨으로써, 변형유도부(221)의 홀을 통하여 고정링(200)의 내부 공간으로 이물질, 세균 등이 침투되는 것을 방지할 수 있다. 즉, 사용자가 반복적으로 용기 개폐용 캡(10)을 개폐하더라도 제품의 위생 상태를 보존할 수 있다.In this way, by adding the configuration of the shielding film 260 according to an embodiment of the present invention, it is possible to prevent foreign substances and bacteria from penetrating into the inner space of the fixing ring 200 through the hole of the deformation induction part 221. . That is, even if the user repeatedly opens and closes the container opening/closing cap 10, the hygienic state of the product can be preserved.
도 6의 (a)와 같이 변형유도부(221) 및 가림막(260)이 형성된 고정링(200)에 응력이 작용하면, 변형유도부(221) 및 가림막(260)의 변형에 의하여 고정링(200)의 원주 길이가 증가될 수 있다. 보다 구체적으로, 사용자가 최초로 용기를 개방하기 위해 용기 개폐용 캡(10)을 회전시키면, 용기 개폐용 캡(10)은 나사산을 따라 회전하면서 조금씩 상승할 수 있다. 또한, 용기 개폐용 캡(10)이 상승함에 따라, 고정턱에 걸려 이동이 제한되는 고정링(200)의 걸림턱(210)에는 응력이 작용할 수 있다. 변형유도부(221)의 홀 및 가림막(260)은 작용하는 응력에 의해 그 폭이 좌우로 증가될 수 있고, 이에 따라 고정링(200)의 원주 길이가 증가될 수 있다.When a stress acts on the fixing ring 200 in which the deformation inducing part 221 and the shielding film 260 are formed as shown in FIG. 6A, the fixing ring 200 is deformed by the deformation of the deformation inducing part 221 and the shielding film 260. The circumferential length of can be increased. More specifically, when the user rotates the container opening and closing cap 10 to open the container for the first time, the container opening and closing cap 10 may rise little by little while rotating along the screw thread. In addition, as the container opening and closing cap 10 rises, a stress may be applied to the locking jaw 210 of the fixing ring 200, which is caught by the fixing jaw and restricts movement. The width of the hole and the shielding film 260 of the deformation inducing part 221 may be increased left and right by the applied stress, and thus the circumferential length of the fixing ring 200 may be increased.
변형유도부(221)의 변형에 의하여 고정링(200)의 원주 길이가 증가되는 방식은 다음과 같다. 먼저, 용기 개폐용 캡(10)이 회전하면서 용기의 상부에 형성된 나사산을 따라 상승할 때, 홀 형태의 변형유도부(221)를 둘러싸도록 형성되는 변형부(220)는 각각 인장에 따른 응력을 받을 수 있다. 그러면, 변형유도부(221)의 상부 및 하부에 위치한 띠 형상의 변형부(220)가 응력에 의하여 두께가 얇아지면서 가로 방향으로 늘어날 수 있다. 즉, 변형유도부(221)의 상부 및 하부에 형성되는 변형부(220)는 각각 소성변형되어 길이가 증가될 수 있다.A method in which the circumferential length of the fixing ring 200 is increased by the deformation of the deformation inducing part 221 is as follows. First, when the cap 10 for opening and closing the container rises along the thread formed on the top of the container while rotating, the deformation parts 220 formed to surround the deformation induction part 221 in the form of a hole each receive a stress according to tension. I can. Then, the belt-shaped deformation portions 220 positioned above and below the deformation inducing portion 221 may increase in the horizontal direction while being thinner due to stress. That is, the deformation portions 220 formed on the upper and lower portions of the deformation inducing portion 221 may be plastically deformed to increase their length.
이에 따라, 사용자가 최초로 용기를 개방하기 위해 용기 개폐용 캡(10)을 회전시키면 변형유도부(221)에도 응력이 작용하고, 이때 변형유도부(221)의 상부 및 하부에 위치한 변형부(220)가 각각 응력에 의해 길이가 증가된 이후에는 다시 원래의 두께 및 길이로 복귀하지 않을 수 있다. 즉, 사용자가 최초로 용기 개폐용 캡(10)을 회전시킨 이후에는, 본 발명의 일 실시예에 따른 고정링(200)의 원주가 증가된 상태를 유지할 수 있다.Accordingly, when the user rotates the container opening and closing cap 10 to open the container for the first time, stress is also applied to the deformation inducing part 221, and at this time, the deformation parts 220 located above and below the deformation inducing part 221 After the length is increased by each stress, it may not return to the original thickness and length again. That is, after the user first rotates the container opening and closing cap 10, the circumference of the fixing ring 200 according to an embodiment of the present invention can be maintained in an increased state.
또한, 변형유도부(221)의 상부 및 하부에 위치한 변형부(220)는 소성변형이 일어나 그 두께가 얇아지더라도 파단되지 않을 수 있다. 구체적으로 용기 개폐용 캡(10)에 인장에 따른 응력이 작용하면, 변형부(220)를 구성하는 고분자 사슬들은 변형 전보다 얇고 긴 형태의 중합체(polymer) 구조를 형성하도록 이동 및 재배열될 수 있다.In addition, the deformation portions 220 positioned above and below the deformation inducing portion 221 may not be fractured even if plastic deformation occurs and the thickness thereof decreases. Specifically, when a stress due to tension acts on the container opening and closing cap 10, the polymer chains constituting the deformation portion 220 may be moved and rearranged to form a thinner and longer polymer structure than before deformation. .
정리하면, 변형유도부(221)의 상부 및 하부를 이루는 얇은 띠 형상의 변형부(220)에 응력이 집중되어 넥변형이 일어나고, 이후 결정화에 의해 강도가 증가되면 얇아진 두께에도 불구하고 파단되지 않은 상태를 유지할 수 있게 된다.In summary, stress is concentrated in the deformed portion 220 of a thin strip shape forming the upper and lower portions of the deformation inducing portion 221 to cause neck deformation, and when the strength is increased by crystallization afterwards, the state is not broken despite the thinner thickness. Will be able to maintain.
이와 마찬가지로, 변형유도부(221)를 차폐하도록 구성되는 가림막(260) 또한 변형에 의하여 고정링(200)의 원주 길이를 증가시킬 수 있다. 즉, 용기 개폐용 캡(10)이 회전하면서 용기의 상부에 형성된 나사산을 따라 상승할 때, 가림막(260)은 인장에 따른 응력을 받을 수 있다. 그러면, 가림막(260)은 두께가 얇아지면서 가로 방향으로 늘어날 수 있고, 이와 같은 소성변형에 의하여 가로 길이가 증가된 상태를 유지할 수 있다. 가림막(260)의 가로 길이가 적어도 일부 길이만큼 증가되면, 고정링(200)의 원주 길이도 그만큼 증가될 수 있다.Likewise, the circumferential length of the fixing ring 200 may be increased by deformation of the covering film 260 configured to shield the deformation inducing part 221. That is, when the cap for opening and closing the container 10 rotates and rises along the thread formed on the top of the container, the shielding film 260 may receive stress due to tension. Then, the shielding film 260 may increase in the horizontal direction as the thickness decreases, and the horizontal length may be increased by such plastic deformation. When the horizontal length of the shielding film 260 is increased by at least a portion of the length, the circumferential length of the fixing ring 200 may also be increased by that amount.
한편, 전술한 바와 같이 가림막(260)의 두께는 필요에 따라 다양하게 조절될 수 있으나, 고정링(200)의 다른 영역보다는 더 얇은 두께를 갖도록 형성됨이 바람직하다. 즉, 가림막(260)의 두께가 고정링(200)의 다른 영역보다 더 얇게 형성됨으로써, 고정링(200)에 작용하는 응력이 가림막(260)을 가로 방향으로 인장시키는 데 집중될 수 있다. 이때 변형부(220)와 마찬가지로, 가림막(260)을 구성하는 고분자 사슬들은 응력에 의하여 변형 전보다 얇고 긴 형태의 중합체(polymer) 구조를 형성하도록 이동 및 재배열될 수 있다. 그리고, 그 고분자 사슬들에 '결정화(crystallization)'가 유도되어 해당 중합체 구조의 강도가 증가될 수 있다.Meanwhile, as described above, the thickness of the shielding film 260 may be variously adjusted as necessary, but it is preferably formed to have a thinner thickness than other regions of the fixing ring 200. That is, since the thickness of the shielding film 260 is formed to be thinner than other regions of the fixing ring 200, stress acting on the fixing ring 200 may be concentrated to tension the shielding film 260 in the horizontal direction. In this case, like the deformation part 220, the polymer chains constituting the shielding film 260 may be moved and rearranged to form a thinner and longer polymer structure than before deformation due to stress. In addition,'crystallization' is induced in the polymer chains, so that the strength of the polymer structure may be increased.
또한, 가림막(260)이 변형유도부(221)의 홀을 차폐하는 위치는 다양할 수 있다. 즉, 가림막(260)은 변형유도부(221)의 홀에 대하여 고정링(200)의 내측면부, 외측면부, 중앙부 중에서 어느 한 곳에 형성됨으로써, 고정링(200)을 관통하는 홀을 차폐할 수 있다.In addition, positions at which the shielding film 260 shields the hole of the deformation inducing part 221 may be various. That is, the shielding film 260 is formed at any one of the inner, outer, and central portions of the fixing ring 200 with respect to the hole of the deformation inducing part 221, so that the hole penetrating the fixing ring 200 may be shielded. .
또한, 도 6의 (b)에 도시된 바와 같이, 고정링(200)에는 변형유도부(221) 및 가림막(260)과 함께, 가림막(260)의 중앙에 세로 방향으로 절개선(250)이 더 형성될 수 있다. 절개선(250)의 구성에 따른 기능은 전술한 바와 같으므로, 본 단락에서는 중복되는 기재를 생략하기로 한다.In addition, as shown in (b) of FIG. 6, in the fixing ring 200, along with the deformation inducing part 221 and the shielding film 260, a cutting line 250 in the vertical direction at the center of the shielding film 260 is further provided. Can be formed. Since the function according to the configuration of the cut line 250 is the same as described above, overlapping descriptions will be omitted in this paragraph.
추가적으로, 고정링(200)에는 변형유도부(221)가 복수로 구비될 수도 있다. 그리고 복수의 변형유도부(221)가 고정링(200)의 중심에 대하여 이루는 각도는 다양할 수 있다. 예를 들어, 고정링(200)에 2개의 변형유도부(221)가 구비되는 경우에 양 변형유도부(221)는 150°, 180° 등의 각도를 이루도록 배치될 수 있다.Additionally, the fixing ring 200 may be provided with a plurality of deformation inducing parts 221. In addition, an angle formed by the plurality of deformation inducing parts 221 with respect to the center of the fixing ring 200 may be various. For example, when two deformation inducing parts 221 are provided in the fixing ring 200, both deformation inducing parts 221 may be disposed to form an angle such as 150°, 180°, or the like.
전술한 바와 같이 가림막(260)의 유무, 변형유도부(221)의 개수 및 각도를 상이하게 하여 고정링(200)을 제작할 수 있고, 각각의 요인에 따라 변형부(220)의 변형되는 정도가 달라질 수 있다. 참고로, 본 발명의 발명자는 가림막(260)의 유무, 변형유도부(221)의 개수 및 각도를 상이하게 하여 용기 개폐용 캡(10)을 개방하는 실험을 수행하였고, 그 결과는 하기의 [표 3]과 같다.As described above, the presence or absence of the shielding film 260, the number and angle of the deformation inducing parts 221 may be different to manufacture the fixing ring 200, and the degree of deformation of the deformation part 220 varies depending on each factor. I can. For reference, the inventor of the present invention performed an experiment of opening the container opening and closing cap 10 by varying the presence or absence of the shielding film 260 and the number and angle of the deformation inducing portions 221, and the results are shown in the following [Table 3].

[표 3]에 기재된 '연결 팁 파단(잔존)'은 최초로 용기 개폐용 캡(10)이 개방되었을 때 파단된 연결 팁의 개수 및 파단되지 않고 잔존한 연결 팁의 개수를 나타낸 것이다. 즉 [표 2]에서와 마찬가지로, 실험 대상이 되는 용기 개폐용 캡(10)의 연결부(300)는 최초에 각각 12개의 연결 팁(310)을 포함하고 있었으며, [표 3]에 나타난 바와 같이 변형유도부(221)의 유무, 개수 및 가림막(260)의 유무에 따라 서로 상이한 개수의 연결 팁(310)이 파단되었다. 그리고 [표 3]의 마지막 행을 참조하면, 가림막(260)에 절개선(250)이 추가로 구비된 경우에는 그렇지 않은 경우에 비하여 더 많은 개수의 연결 팁(310)이 잔존한 것을 확인할 수 있다.The'connection tip fracture (remaining)' described in [Table 3] indicates the number of connection tips that are broken when the container opening and closing cap 10 is opened for the first time and the number of connection tips that remain without being broken. That is, as in [Table 2], the connection part 300 of the container opening and closing cap 10 to be tested initially included 12 connection tips 310, respectively, and modified as shown in [Table 3]. Depending on the presence or absence of the induction part 221, the number, and the presence or absence of the shielding film 260, a different number of connection tips 310 were broken. And referring to the last row of [Table 3], in the case where the incision line 250 is additionally provided in the shielding film 260, it can be seen that a larger number of connection tips 310 remain than in the case where the incision line 250 is additionally provided. .
또한, 각각의 요인에 따라 변형유도부(221)의 상부 및 하부에 형성되는 변형부(220)의 길이가 소성변형으로 증가되는 정도가 서로 상이함을 알 수 있다. 즉, 변형부(220)의 길이가 증가함에 따라 최초에 구비되어 있던 12개의 연결 팁(310) 중에서 일부가 파단되지 않을 수 있고, 연결 팁(310) 중에서 일부가 잔존함으로써 고정링(200)이 본체(100)와 함께 일체로써 용기 바디로부터 취출될 수 있다.In addition, it can be seen that the lengths of the deformation portions 220 formed on the upper and lower portions of the deformation inducing portion 221 are different from each other according to each factor. That is, as the length of the deformable part 220 increases, some of the 12 connection tips 310 initially provided may not be broken, and some of the connection tips 310 remain, so that the fixing ring 200 It can be taken out from the container body as an integral part with the body 100.
참고로, 도 6의 (b)와 같이 고정링(200)에 가림막(260)과 절개선(250)이 동시에 구비되면, 각각의 구성이 단독으로 구비되는 것보다 작용하는 응력에 따라 고정링(200)의 원주 길이가 증가되는 효과가 커질 수 있다. 따라서 절개선(250)이 구비되지 않는 경우보다 가림막(260)의 두께를 더 두껍게 형성하더라도, 사용자가 용기 개폐용 캡(10)을 개방하는 동작에 의하여 고정링(200)의 원주 길이가 용이하게 증가될 수 있다.For reference, as shown in (b) of FIG. 6, when the shielding film 260 and the incision line 250 are simultaneously provided on the fixing ring 200, the fixing ring ( 200) may increase the effect of increasing the circumferential length. Therefore, even if the thickness of the shielding film 260 is formed thicker than the case where the incision line 250 is not provided, the circumferential length of the fixing ring 200 is easily reduced by the operation of opening the container opening and closing cap 10 by the user. Can be increased.
또한, 가림막(260)과 절개선(250)이 동시에 구비되는 경우에도 절개선(250)의 구체적인 형태가 전술한 도 5의 (a) 내지 (d)와 같이 다양하게 형성될 수 있음은 물론이다.In addition, even when the shielding film 260 and the cutting line 250 are provided at the same time, a specific shape of the cutting line 250 may be variously formed as shown in FIGS. 5A to 5D described above. .

In addition, when the circumference of the fixing ring 200 is increased, at least some of the plurality of connection tips 310 of the connection part 300 according to an embodiment of the present invention may not be broken. That is, the connection tip 310 is broken due to the action of the locking jaw 210 applied to the fixed jaw, so the connection tip 310 that is broken when the area applied to the fixed jaw decreases due to an increase in the circumference of the fixing ring 200 The number of can also be reduced.
그에 따라, 연결부(300)를 구성하는 복수의 연결 팁(310) 중 적어도 하나가 파단되지 않고 결합을 유지하게 되고, 본체(100) 및 고정링(200)은 결속된 일체로서의 상태를 유지하면서 용기 바디로부터 분리될 수 있게 된다. 즉, 사용자가 최초로 용기 개폐용 캡(10)을 회전시킨 이후에는 연결 팁(310)이 더이상 파단되지 않을 수 있고, 그 이후부터 본체(100) 및 고정링(200)이 결속된 일체로서 용기 바디와 결합 또는 분리될 수 있다.Accordingly, at least one of the plurality of connection tips 310 constituting the connection part 300 is not broken and maintains the connection, and the main body 100 and the fixing ring 200 maintains the state as a united unit while maintaining the container It can be separated from the body. That is, after the user rotates the container opening and closing cap 10 for the first time, the connection tip 310 may no longer be broken, and after that, the body 100 and the fixing ring 200 are bound together as an integral part of the container body. Can be combined with or separated from.
도 7은 본 발명의 일 실시예에 따른 취출부(230)를 나타낸 고정링(200)의 평면도이다.7 is a plan view of the fixing ring 200 showing the take-out part 230 according to an embodiment of the present invention.
전술한 바와 같이, 본 발명의 일 실시예에 따른 고정링(200)에는, 용기 개폐용 캡(10)이 용기 바디로부터 분리됨에 있어 걸림턱(210)의 적어도 일부가 용기 바디에 형성된 고정턱에 걸림이 없이 고정링(200)이 본체(100)와 결속된 일체로 분리되도록 하는 수단이 구비될 수 있다.As described above, in the fixing ring 200 according to an embodiment of the present invention, since the container opening and closing cap 10 is separated from the container body, at least a part of the locking jaw 210 is attached to the fixing jaw formed in the container body. A means may be provided so that the fixing ring 200 is integrally separated from the main body 100 without being jammed.
본 발명의 추가 실시예에 따르면, 상기의 수단은 걸림턱(210)이 형성되지 않거나 또는 다른 영역보다 더 낮은 높이의 걸림턱(210)이 형성되는 취출부(230)를 포함할 수 있으며, 도 7에는 걸림턱(210)이 형성되지 않은 영역에 해당하는 취출부(230)의 구성을 예시적으로 도시한다.According to a further embodiment of the present invention, the means may include a take-out part 230 in which the locking projection 210 is not formed or the locking projection 210 having a lower height than other regions is formed. 7 illustrates an exemplary configuration of the take-out part 230 corresponding to a region in which the locking protrusion 210 is not formed.
구체적으로, 취출부(230)는 복수의 걸림턱(210) 중 일부가 형성되지 않는 형태로 구비될 수 있다. 또한, 취출부(230)는 걸림턱(210)의 일부 영역이 다른 영역보다 더 낮은 높이로 돌출되는 형태로 구비될 수도 있다. 즉, 취출부(230)가 구비된 영역은 걸림턱(210)이 없거나 낮게 형성되어, 용기 바디에 형성된 고정턱에 걸리지 않을 수 있다.Specifically, the take-out part 230 may be provided in a form in which some of the plurality of locking projections 210 are not formed. In addition, the take-out part 230 may be provided in a form in which some regions of the locking protrusions 210 protrude to a lower height than other regions. That is, the region in which the take-out part 230 is provided may not be caught by the fixing jaw formed on the container body because the locking jaw 210 is not or is formed low.
사용자는 취출부(230)가 포함된 고정링(200)을 용기 바디로부터 분리시킬 때, 취출부(230)가 구비된 영역을 상부로 먼저 들어올린 후에 나머지 영역을 들어올릴 수 있다. 즉, 취출부(230)를 이용하여 용이하게 고정링(200)을 분리할 수 있다.When separating the fixing ring 200 including the take-out part 230 from the container body, the user may first lift the area provided with the take-out part 230 to the top and then lift the remaining area. That is, the fixing ring 200 can be easily separated by using the take-out part 230.
본 발명의 추가 실시예에 따르면, 상기한 수단은 고정링(200)의 측면 적어도 일부 영역에 형성되어 작용하는 응력에 의해 고정링(200)의 원주를 증가시키도록 구성되는 변형부(220)를 더 포함하고, 이와 같이 변형부(220)와 취출부(230)를 모두 구비하는 구성에서는 변형부(220)와 취출부(230)가 고정링(200)의 원주 상에서 서로 대면하는 위치에 구비될 수 있다.According to a further embodiment of the present invention, the above-described means includes a deformation portion 220 configured to increase the circumference of the fixing ring 200 by a stress formed and acting on at least a portion of the side surface of the fixing ring 200. Further including, in the configuration including both the deformable part 220 and the take-out part 230 as described above, the deformable part 220 and the take-out part 230 may be provided at positions facing each other on the circumference of the fixing ring 200. I can.
보다 구체적으로, 취출부(230)가 형성되는 고정링(200)에 변형부(220)가 추가로 형성되도록 할 수 있다. 즉, 본 발명의 추가 실시예에 따른 고정링(200)은, 변형부(220) 및 취출부(230)를 모두 구비할 수도 있다.More specifically, the deformable part 220 may be additionally formed on the fixing ring 200 in which the take-out part 230 is formed. That is, the fixing ring 200 according to a further embodiment of the present invention may include both the deformable part 220 and the take-out part 230.
고정링(200)이 복수의(예를 들어, 2개의) 변형부(220)를 포함할 때와 마찬가지로, 변형부(220) 및 취출부(230)의 배치 관계에 따라, 변형부(220)의 소성변형으로 증가되는 길이 및 연결 팁(310)이 파단되는 개수가 상이할 수 있다.Similar to the case where the fixing ring 200 includes a plurality of (for example, two) deformable portions 220, according to the arrangement relationship of the deformable portion 220 and the take-out portion 230, the deformable portion 220 The length increased by the plastic deformation of and the number of fractures of the connection tip 310 may be different.
참고로, 본 발명의 발명자는 변형부(220) 및 취출부(230)의 배치를 상이하게 하여 용기 개폐용 캡(10)을 개방하는 실험을 수행하였고, 그 결과는 하기의 [표 4]와 같다.For reference, the inventor of the present invention performed an experiment of opening the container opening and closing cap 10 by making the arrangement of the deformable part 220 and the take-out part 230 different, and the results are shown in [Table 4] below. same.

[표 4]의 실험결과는 취출부(230)만 형성되는 경우와, 취출부(230) 및 변형부(220)가 동시에 형성되는 경우에 각각의 변형부(220)가 증가된 길이를 나타낸다. 참고로, 본 발명의 발명자가 실험에서 사용한 고정링(200)은 외부 원주 길이가 98mm, 변형 전의 변형부(220)의 길이가 2.2mm에 해당하는 것이다.The experimental results in [Table 4] show the length of each deformable portion 220 increased when only the ejection portion 230 is formed and when the ejection portion 230 and the deformable portion 220 are formed at the same time. For reference, the fixed ring 200 used in the experiment by the inventor of the present invention has an outer circumference of 98 mm and a length of the deformed portion 220 before deformation is 2.2 mm.
또한, [표 4]에 기재된 '연결부 유지(파단)'은 최초로 용기 개폐용 캡(10)이 개방되었을 때 파단되지 않고 유지된 연결 팁의 개수 및 파단된 연결 팁의 개수를 나타낸 것이다. 즉, 실험 대상이 되는 용기 개폐용 캡(10)의 연결부(300)는 최초에 각각 12개의 연결 팁(310)을 포함하고 있었으며, [표 4]에 나타난 바와 같이 취출부(230)의 유무 및 변형부(220)의 증가된 길이에 따라 서로 상이한 개수의 연결 팁(310)이 파단되었다.In addition, the'connection part maintenance (breaking)' described in [Table 4] indicates the number of connection tips maintained without breaking when the container opening and closing cap 10 is opened for the first time, and the number of broken connection tips. That is, the connection part 300 of the container opening/closing cap 10 to be tested initially included 12 connection tips 310, respectively, and the presence or absence of the take-out part 230 as shown in [Table 4] and According to the increased length of the deformable part 220, a different number of connection tips 310 are broken.
[표 4]에 나타난 바와 같이, 취출부(230)의 유무에 따라 각각의 변형부(220)가 증가되는 길이 및 파단되는 연결 팁(310)의 개수가 서로 상이함을 알 수 있다.As shown in [Table 4], it can be seen that depending on the presence or absence of the take-out part 230, the length at which each deformable part 220 increases and the number of connection tips 310 to be broken are different from each other.
또한, 변형부(220) 및 취출부(230)가 이루는 각도에 따라서도 변형부의 증가되는 길이가 상이함을 알 수 있다. 특히, 고정링(200)이 취출부(230) 및 변형부(220)를 동시에 포함하면서, 양 구성 간에 서로 180도의 각도를 이루도록 할 때 전체 길이가 가장 크게 증가되고 취출(즉 고정링(200)의 분리)이 용이했음을 확인할 수 있다.In addition, it can be seen that the increased length of the deformable portion is different according to the angle formed by the deformable portion 220 and the take-out portion 230. In particular, when the fixing ring 200 includes the take-out part 230 and the deformable part 220 at the same time, the total length increases the most when the two components form an angle of 180 degrees to each other and take out (that is, the fixed ring 200). Separation) was easy.
도 8의 (a)는 본 발명의 일 실시예에 따라 얇은 두께를 갖는 변형부(220)에 절개선(250)이 형성된 고정링(200)의 사시도이고, 도 8의 (b)는 본 발명의 일 실시예에 따라 얇은 두께를 갖는 변형부(220)에 가림막(260)이 형성된 고정링(200)의 사시도이다.Figure 8 (a) is a perspective view of the fixing ring 200 in which the cut line 250 is formed in the deformable portion 220 having a thin thickness according to an embodiment of the present invention, and Figure 8 (b) is the present invention It is a perspective view of the fixing ring 200 in which the shielding film 260 is formed on the deformable part 220 having a thin thickness according to an embodiment of the present invention.
도 8의 (a) 및 (b)에 도시되는 바와 같이, 본 발명의 일 실시예에 따른 변형부(220)는 고정링(200)의 측면 적어도 일부 영역에서 고정링(200)의 다른 영역보다 더 얇은 두께를 갖도록 형성될 수 있다. 변형부(220)의 두께가 얇게 형성되는 것은 결과적으로 고정링(200)의 측면 적어도 일부 영역에 변형유도부(221) 및 가림막(260)이 형성되는 것과 동일한 효과를 나타낼 수 있다.As shown in (a) and (b) of FIG. 8, the deformable part 220 according to an embodiment of the present invention is at least in a portion of the side of the fixing ring 200 than other regions of the fixing ring 200. It can be formed to have a thinner thickness. As a result, the thickness of the deformable part 220 is thin, and as a result, the deformation inducing part 221 and the shielding film 260 are formed on at least a part of the side surface of the fixing ring 200.
구체적으로, 용기 개폐용 캡(10)이 회전하면서 용기의 상부에 형성된 나사산을 따라 상승할 때, 얇은 두께로 형성되는 변형부(220)는 인장에 따른 응력을 받을 수 있다. 그러면, 변형부(220)는 응력에 의하여 두께가 더욱 얇아지면서 가로 방향으로 늘어날 수 있다. 즉, 고정링(200)의 다른 영역보다 더 얇은 두께로 형성되는 변형부(220)에 인장에 따른 응력이 집중됨으로써, 변형부(220)가 소성변형되어 길이가 증가될 수 있다.Specifically, when the cap 10 for opening and closing the container rises along the thread formed on the top of the container while rotating, the deformation portion 220 formed in a thin thickness may receive stress due to tension. Then, the deformation portion 220 may be increased in the horizontal direction while being thinner due to the stress. That is, as the stress due to tension is concentrated in the deformation portion 220 formed to have a thinner thickness than other regions of the fixing ring 200, the deformation portion 220 may be plastically deformed to increase the length.
그리고 소성변형에 의하여 변형부(220)의 길이가 증가된 이후에는 다시 원래의 두께 및 길이로 복귀하지 않을 수 있다. 즉, 사용자가 최초로 용기 개폐용 캡(10)을 회전시킨 이후에는, 본 발명의 일 실시예에 따른 고정링(200)의 원주가 증가된 상태를 유지할 수 있다.In addition, after the length of the deformation portion 220 is increased by plastic deformation, the original thickness and length may not be restored again. That is, after the user first rotates the container opening and closing cap 10, the circumference of the fixing ring 200 according to an embodiment of the present invention can be maintained in an increased state.
본 발명의 추가 실시예에 따르면, 도 8의 (a)에 도시되는 바와 같이, 다른 영역보다 더 얇은 두께를 갖도록 형성되는 변형부(220)의 구성에 절개선(250)의 구성이 더 부가될 수 있다. 이와 같은 복수의 구성이 고정링(200)에 동시에 형성되면, 각각의 구성이 단독으로 구비되는 것보다 작용하는 응력에 따라 고정링(200)의 원주 길이가 증가되는 효과가 커질 수 있다. 또한, 변형부(220)와 절개선(250)이 동시에 구비되는 경우에도 절개선(250)의 구체적인 형태가 전술한 도 5의 (a) 내지 (d)와 같이 다양하게 형성될 수 있음은 물론이다.According to a further embodiment of the present invention, as shown in (a) of FIG. 8, the configuration of the incision line 250 may be further added to the configuration of the deformable portion 220 formed to have a thinner thickness than other regions. I can. When such a plurality of configurations are formed on the fixing ring 200 at the same time, the effect of increasing the circumferential length of the fixing ring 200 according to the applied stress may be greater than that of each component being provided alone. In addition, even when the deformable part 220 and the cut line 250 are provided at the same time, the specific shape of the cut line 250 may be variously formed as shown in FIGS. 5A to 5D described above. to be.
추가적으로, 도 8의 (b)에 도시되는 바와 같이, 다른 영역보다 더 얇은 두께를 갖도록 형성되는 변형부(220)의 구성에 변형유도부(221) 및 가림막(260)의 구성이 더 부가될 수도 있으며, 도면에는 도시되지 않았으나 변형부(220), 변형유도부(221), 가림막(260) 및 절개선(250)의 구성이 모두 포함되도록 형성하는 것도 가능하다. 즉, 용기 개폐용 캡(10)을 제조하는 기술 수준, 설비, 환경 등의 조건에 따라 각각의 구성을 자유롭게 조합할 수 있을 것이다. 또한, 이때 변형부(220)는 변형유도부(221)와 연속되어, 작용하는 응력에 의해 고정링(200)의 원주를 증가시키도록 구성될 수 있다.Additionally, as shown in (b) of FIG. 8, the configuration of the deformation inducing part 221 and the covering film 260 may be further added to the configuration of the deformation part 220 formed to have a thinner thickness than other regions. , Although not shown in the drawing, it is also possible to form the deformation portion 220, the deformation inducing portion 221, the shielding film 260, and the incision line 250 to include all of the configurations. That is, it will be possible to freely combine the respective configurations according to conditions such as technical level, equipment, and environment for manufacturing the container opening and closing cap 10. In addition, at this time, the deformation portion 220 may be configured to increase the circumference of the fixing ring 200 by a stress applied in succession with the deformation inducing portion 221.
한편, 얇은 두께를 갖는 변형부(220), 변형유도부(221) 및 가림막(260)의 구성이 고정링(200)에 함께 형성되는 경우에, 가림막(260)이 변형유도부(221)의 홀을 차폐하는 위치는 다양할 수 있다. 즉, 가림막(260)은 도 6에서 전술한 바와 같이 변형유도부(221)의 홀에 대하여 고정링(200)의 내측면부, 외측면부, 중앙부 중에서 어느 한 곳에 형성됨으로써, 고정링(200)을 관통하는 홀을 차폐할 수 있다. 또한 변형유도부(221)의 홀을 차폐하는 것에 더하여, 가림막(260)은 변형부(220)의 일 측면에 필름과 같은 형태로 추가로 구비되는 것도 가능하다.On the other hand, when the configuration of the deformation portion 220, the deformation inducing portion 221 and the shielding film 260 having a thin thickness is formed together in the fixing ring 200, the shielding film 260 is formed to the hole of the deformation inducing portion 221 The location of the shield can be varied. That is, the shielding film 260 is formed at any one of the inner side, outer side, and central part of the fixing ring 200 with respect to the hole of the deformation inducing part 221 as described above in FIG. 6, thereby penetrating the fixing ring 200. It is possible to shield the hole. In addition to shielding the hole of the deformation inducing part 221, the shielding film 260 may be additionally provided in the form of a film on one side of the deformation part 220.
도 9는 본 발명의 일 실시예에 따라 접힌 형태의 변형부(220)가 응력에 의해 펼쳐지는 상태를 각각 나타낸 것이다.9 is a diagram illustrating a state in which the deformation portions 220 in a folded form are unfolded by stress according to an embodiment of the present invention.
도 9에 도시되는 바와 같이, 본 발명의 일 실시예에 따른 변형부(220)는 접힌 형태를 갖도록 구비될 수 있다. 즉, 사용자가 최초로 용기를 개방하기 이전의 상태에서, 변형부(220)는 도 9의 (a)에서 좌측 도면과 같이 곡선으로 구부러지듯이 접혀 있거나, 도 9의 (b)에서 좌측 도면과 같이 지그재그로 접철되는 방식으로 접혀 있을 수 있다.As shown in FIG. 9, the deformable part 220 according to an embodiment of the present invention may be provided to have a folded shape. That is, in the state before the user first opens the container, the deformable part 220 is folded in a curved shape as shown in the left drawing in FIG. 9(a), or zigzag as shown in the left drawing in FIG. 9(b). It can be folded in such a way that it is folded into.
이후 사용자가 용기를 개방하기 위해 용기 개폐용 캡(10)을 회전시키면, 용기 개폐용 캡(10)은 나사산을 따라 회전하면서 조금씩 상승할 수 있다. 또한, 용기 개폐용 캡(10)이 상승함에 따라, 고정턱에 걸려 이동이 제한되는 고정링(200)의 걸림턱(210)에는 응력이 작용할 수 있다. 그러면 접혀 있던 변형부(220)는 도 9의 우측 도면들과 같이 가로 방향으로 펼쳐질 수 있고, 이에 따라 고정링(200)의 원주 길이가 증가할 수 있다.Thereafter, when the user rotates the container opening/closing cap 10 to open the container, the container opening/closing cap 10 may rise little by little while rotating along the screw thread. In addition, as the container opening and closing cap 10 rises, a stress may be applied to the locking jaw 210 of the fixing ring 200, which is caught by the fixing jaw and restricts movement. Then, the folded deformable part 220 may be unfolded in the horizontal direction as shown in the right views of FIG. 9, and accordingly, the circumferential length of the fixing ring 200 may be increased.
참고로, 도면에는 도시되지 않았으나, 접힌 형태의 변형부(220)에는 전술한 바와 같은 변형유도부(221), 가림막(260) 및 절개선(250)의 구성이 선택적으로 더 부가될 수 있음은 당연하다. 또한, 복수의 구성들이 동시에 구비되는 경우에도 절개선(250)의 구체적인 형태가 전술한 도 5의 (a) 내지 (d)와 같이 다양하게 형성될 수 있다.For reference, although not shown in the drawing, it is natural that the configuration of the deformation inducing part 221, the shielding film 260, and the incision line 250 as described above may be optionally further added to the folded deformation part 220 Do. In addition, even when a plurality of configurations are provided at the same time, a specific shape of the cut line 250 may be variously formed as shown in FIGS. 5A to 5D described above.
도면에는 도시되지 않았으나, 본 발명의 다른 실시예에 따른 고정링(200)은, 적어도 일 면이 고정링(200)의 두께보다 얇고, 변형에 필요한 응력이 고정링(200)보다 낮으며, 용기 개폐용 캡(10)의 개방 시 복수의 연결 팁(310)이 전부 절단되기 전에 고정링(200)의 원주를 증가시키도록 소성변형이 일어나는 변형부(220)를 포함할 수 있다. 또한 고정링(200)은, 고정링(200)의 일부가 제거되고, 동일한 응력에서 변형부(220)보다 신장율이 높으며, 변형부(220)와 연속하여 형성되는 개방부(미도시)를 더 포함할 수 있다.Although not shown in the drawings, the fixing ring 200 according to another embodiment of the present invention has at least one surface thinner than the thickness of the fixing ring 200, and the stress required for deformation is lower than that of the fixing ring 200, and the container When the opening/closing cap 10 is opened, the plurality of connection tips 310 may include a deformation part 220 in which plastic deformation occurs so as to increase the circumference of the fixing ring 200 before all of the connection tips 310 are cut. In addition, the fixing ring 200, a part of the fixing ring 200 is removed, the elongation is higher than that of the deformed portion 220 at the same stress, and the opening portion (not shown) formed continuously with the deformed portion 220 is further Can include.
이에 따라, 본 발명에 따른 고정링(200)에 홀 형태의 변형유도부(221)가 구비되지 않더라도, 고정링(200)의 일 영역에 형성되는 변형부(220)의 두께 조절만으로도 고정링(200)의 원주를 증가시킬 수 있다. 즉, 고정링(200)의 다른 영역보다 얇게 형성되는 변형부(220)에 소성변형이 일어남으로써 고정링(200)의 원주가 증가될 수 있다.Accordingly, even if the fixing ring 200 according to the present invention is not provided with the deformation inducing part 221 in the form of a hole, the fixing ring 200 can be adjusted only by adjusting the thickness of the deformation part 220 formed in one area of the fixing ring 200. You can increase the circumference of ). That is, plastic deformation occurs in the deformation portion 220 formed to be thinner than other regions of the fixing ring 200, so that the circumference of the fixing ring 200 may be increased.
