Description

Cap opener

Technical Field

The present invention relates to a screw cap to be mounted to a mouth portion of a container and a cap opener mounted to the screw cap to prevent removal of a ring for manually opening the screw cap.

Background

As such a cap opener, a structure disclosed in the following patent document 1 is known. The container opened by the lid opener contains roasted coffee beans having a property of emitting carbon dioxide gas. Therefore, when the container for holding the roasted coffee beans is filled with the roasted coffee beans, the internal pressure of the container is increased by the carbon dioxide gas. Therefore, in order to improve the sealing property, a screw cap is firmly fastened to the mouth portion of the container. Considerable grip and wrist strength is required when the user manually unscrews the screw cap. Therefore, the screw cap is opened using the cap opener as a dedicated jig. The lid opener has a needle portion for puncturing the lid to release the internal pressure before opening the lid.

As described above, although the screw cap is firmly fastened to be opened with a dedicated cap opener, it is also possible to manually open if the user has a great wrist force. Then, the screw cap is opened in a state where the internal pressure is higher than the external pressure, and the content is discharged. Therefore, in patent document 1, a ring is attached around the screw cap to prevent the screw cap from being opened by hand. Also, the ring is also removed using a cap opener.

The method of using the lid opener in patent document 1 is as follows. The lid opener has a head portion covering the screw lid and a pair of arm portions. The arm portion is held by a hand to perform a closing operation, thereby bringing the abutting portion of the head portion into pressure contact with the screw cap. Then, the cap opener is rotated to remove the screw cap from the mouth of the container. At this point, the ring is still mounted at the mouth. Therefore, the cap opener is attached to the mouth portion of the container again, and the engaging portion provided on the head portion is operated to engage with the ring, thereby detaching the ring from the mouth portion.

Problems to be solved by the invention

The problem of the lid opener disclosed in the above-mentioned patent document 1 is as follows. That is, after the screw cap is removed, the ring must be removed again, which is a problem of time-consuming operation.

The present invention has been made in view of the above circumstances, and the problems to be solved by the present invention are: provided is a cap opener capable of efficiently removing a screw cap and a ring when removing the screw cap having the ring around the screw cap.

Means for solving the problems

A cap opener of the present invention for solving the above-described problems is a cap opener for removing a screw cap attached to a mouth portion of a container and a ring attached to a periphery of the screw cap, the ring being for preventing manual opening of the screw cap, the cap opener comprising: a head portion covering the screw cap, and a pair of arm portions extending from the head portion; the head has: a contact portion which can be brought into pressure contact with or engaged with a peripheral surface portion of the screw cap, a top surface facing portion which faces a top surface portion of the screw cap, a needle portion which is provided in the top surface facing portion and can pass through the top surface portion of the screw cap, and an engaging portion which can be engaged with the ring; when the pair of arm portions are operated in a closing direction of the pair of arm portions, the abutting portion is brought into pressure contact with or engaged with a peripheral surface portion of the screw cap, and the engaging portion is engaged with the ring, so that the screw cap and the ring can be removed at the same time.

The operation and effect of the lid opener adopting such a structure will be described below. The lid opener has a head portion and a pair of arm portions. The head portion has a needle portion, and the needle portion penetrates through the top surface portion of the screw cap, whereby the internal pressure in the container can be released. The head portion has a contact portion, and the contact portion can be brought into pressure contact with or engaged with the peripheral surface portion of the screw cap by closing the pair of arm portions. Therefore, the screw cap can be opened after the internal pressure is released by the needle portion. The head portion has an engaging portion engageable with the ring. The abutting portion is in pressure contact with or engaged with the screw cap, and the engaging portion is engaged with the ring. Thus, the ring can be removed at the same time as the screw cap. Therefore, it is possible to provide a cap opener capable of efficiently removing a screw cap and a ring.

In the present invention, it is preferable that the head portion, the arm portion, and the engaging portion are integrally formed of resin.

The head, the arm, and the engagement portion are formed integrally, whereby the number of parts can be reduced, which contributes to cost reduction. Further, since the head portion, the arm portion, and the engaging portion are integrally formed, the abutting portion and the engaging portion of the head portion simultaneously operate when the arm portion is operated. Therefore, the structure of removing the screw cap and the ring at the same time can be easily realized.

Preferably, the needle fixing portion includes a needle fixing portion that holds an upper end portion of the needle portion by the top surface facing portion, and a needle support portion that supports the needle fixing portion, the needle fixing portion includes a through hole that penetrates the needle fixing portion in a vertical direction, the needle portion is formed of a tubular member, an inner space of the needle portion communicates with the through hole of the needle fixing portion, and the needle support portion is integrally formed with the head portion.

The top surface opposite portion provided on the head portion has a needle fixing portion and a needle supporting portion. The needle portion formed by the tubular member is fixed to the needle fixing portion. In this way, the needle portion penetrates the top surface portion of the screw cap, whereby the internal pressure can be released to the outside through the needle portion. The needle fixing portion is supported by a needle supporting portion integrally formed with the head portion. Since the needle support portion is formed integrally with the head portion, it is possible to contribute to reduction in component cost.

In the present invention, it is preferable that the head portion has a frame portion having a C-shape in a plan view, and the pair of arm portions are operated to elastically deform a C-shaped open position of the frame portion in a closing direction, and the contact portion can be brought into pressure contact with or engaged with a peripheral surface portion of the screw cap, and the needle support portion and the frame portion are integrally connected to each other on a side opposite to the C-shaped open position.

The head portion has a frame portion formed in a C-shape, and the open position of the C-shape of the frame portion can be opened or closed by a pair of arm portions. By performing the closing operation, the abutting portion is brought into pressure contact with or engaged with the peripheral surface portion of the screw cap, so that the screw cap can be operated in the opening direction. The needle support portion is formed integrally with the frame portion, and is connected to the frame portion on the side opposite to the open position of the C-shape. This side is a position where the arm portion is not elastically deformed by the operation. Therefore, the needle support portion can be formed in a state of being connected to the frame portion without affecting the opening and closing operation of the arm portion.

In the present invention, it is preferable that the needle support portion has a circular shape in plan view, and an arc-shaped groove is formed between the needle support portion and the frame portion in a state before the pair of arm portions are closed.

With this configuration, the arm portion is easily elastically deformed by forming the arc-shaped groove, and the operability is improved.

In the present invention, it is preferable that the needle fixing portion is formed in a cap shape covering the needle supporting portion.

With this configuration, the needle holder can be assembled by only covering the needle holder with the needle fixing portion of the cap to which the needle portion is fixed.

Detailed Description

Preferred embodiments of the cap opener of the present invention will be described with reference to the accompanying drawings. As shown in fig. 1, the lid opener is used when removing a screw lid C2. The lid opener applies a rotational torque to the screw lid C2, thereby enabling removal of the screw lid C2. The ring a attached to the periphery of the screw cap C2 can be removed together with the screw cap C2.

< vessel and screw cap >

The container C1 and the screw cap C2 are made of aluminum alloy and can withstand an internal pressure of 0.35MPa or more. The container C1 is filled with roasted coffee beans. The internal pressure of the container C1 may be 0.25 to 0.35MPa due to carbon dioxide gas released from the coffee beans.

The mouth of the container C1 has a cylindrical shape, and a screw thread is formed on the outer peripheral surface of the mouth. Screw cap C2 sealed container C1. The screw cap C2 has a cylindrical shape, and includes a disc-shaped top surface portion C21 and a cylindrical peripheral surface portion C22 formed at the edge of the top surface portion C21. A thread is formed on the inner peripheral surface of the peripheral surface portion C22. After the container C1 was filled with coffee beans, screw cap C2 was screwed onto the mouth of container C1.

< Ring >

The ring a is an obstacle for preventing opening by a method other than the lid opener B (for example, another tool or a human hand), and is attached to the mouth of the container C1 in the baking factory. The ring a can freely rotate with respect to the mouth of the container C1 and the screw cap C2, and even if the user rotates the ring a, the rotational torque does not act on the screw cap C2. Further, the container C1 containing coffee beans is distributed on the market with the ring a attached to the mouth, and reaches the consumer.

As shown in fig. 2 (a), the ring a includes a ring main body a1, a plurality of guide portions a2 rising from the ring main body a1, and a plurality of protruding portions A3 protruding from the ring main body a1 to the inside in the radial direction of the ring main body a 1. Ring a is made of synthetic resin.

As shown in fig. 2 (b), the ring main body a1 has a cylindrical portion a11 and a flange portion a12 formed at an upper end portion of the cylindrical portion a 11. The flange portion a12 extends outward from the outer peripheral surface of the cylindrical portion a 11. As shown in fig. 9, the ring body a1 is formed so that its inner diameter is larger than the outer diameter of the screw cap C2, and the inner peripheral surface of the ring body a1 faces the lower half of the peripheral surface portion C22 of the screw cap C2.

As shown in fig. 2 (a), each of the guide portions a2 is formed in a curved plate shape and is arranged at intervals in the circumferential direction of the ring main body a 1. As shown in fig. 2 (b), the guide portion a2 is disposed along the outer edge of the flange portion a 12. The shape of each guide portion a2 as viewed from above is an arc. As shown in fig. 2 (c), each guide portion a2 rises substantially vertically upward from the upper surface of the flange portion a 12. The guide portion a2 is rectangular when viewed from the front. As shown in fig. 10, the guide portion a2 is located away from the circumferential surface portion C22 of the screw cap C2, and the inner circumferential surface of the guide portion a2 faces the upper half of the circumferential surface portion C22.

As shown in fig. 2 (a), the extension portion A3 extends in a cantilever manner from the inner peripheral surface of the lower end portion of the cylindrical portion a 11. The extension A3 is flat, and as shown in fig. 2 (b), the extension A3 is rectangular in shape when viewed from above. The plurality of protruding portions A3 are arranged at intervals in the circumferential direction of the cylindrical portion a 11. As shown in fig. 10, the tip of the extension A3 abuts against or approaches the root of the mouth of the container C1, and when the ring a is about to fall off from the mouth during transportation of the container C2 or the like, the extension A3 engages with the screw thread of the container C1 or the lower end of the screw cap C2. Since the ring a is hard to fall off by providing the projecting portion a3, the ring a can be prevented from falling off accidentally. Although not shown, when a flange or a step is formed at the mouth of container C2, the tip of extension A3 may engage with the flange or the like.

< Cap opener >

As shown in fig. 1, the lid opener B has a head B1 covering the screw lid C2 and a pair of arms B2, B2 extending from the head B1. The cap opener B has a function of reducing the internal pressure of the container C1, a function of applying a rotational torque to the screw cap C2, and a function of removing the ring a.

Fig. 1 is a perspective view of the door opener B as viewed from above. Fig. 3 is an exploded perspective view of the door opener B as viewed from above. Fig. 4 is an exploded perspective view of the door opener B as viewed from below. Fig. 5 is a plan view of the head portion B1 viewed from the upper surface, and fig. 6 is a plan view of the head portion B1 viewed from below.

The head B1 includes a frame 1 having a C-shape in plan view, a contact portion 2 in pressure contact with the circumferential surface portion C22 of the screw cap C2, a top surface facing portion 3 facing the top surface portion C21 of the screw cap C2, a needle portion 6 capable of penetrating the top surface portion C21, and an engaging portion 8 capable of engaging with the outer periphery of the ring a. As shown in fig. 4, a guide groove into which the guide portion a2 of the ring a can be inserted is formed in the lower surface of the head portion B1.

The arm portions B2 are arranged in parallel at intervals. One arm portion B2 is connected to one end portion of the frame 1, and the other arm portion B2 is connected to the other end portion of the frame 1. That is, each arm portion B2 is cantilevered (cantilever beam-like) from the frame portion 1. In addition, it is preferable that a plurality of convex portions of the anti-slip portion be formed on the surface of the portion of the arm portion B2 that is the handle (grip).

The distance between the arm portions B2 gradually decreases as the arm portions approach the frame 1, and is smallest at the base end portion (the portion immediately adjacent to the frame 1). When the arm portions B2 are gripped and moved closer to each other, the distance from the frame 1 increases, and as a result, the distance between the arm portions B2 gradually increases as the arm portions B2 move closer to the frame 1, and the distance between the arm portions B2 is the largest at the base end portion. Further, the distance between the base end portions of the arm portions B2 when the arm portions B2 are brought close to each other is smaller than the distance between the base end portions of the arm portions B2 when the arm portions B2 are not brought close to each other. The shape of the arm portion B2 can be variously changed, and is not limited to the present embodiment.

The frame 1 of the head B1 and the pair of arm portions B2 are formed of, for example, a thermoplastic resin material (e.g., polypropylene) and are integrally formed by injection molding. A space V1 surrounded by the frame 1 and having a circular shape in a bottom view is formed, and a space V2 sandwiched between both ends of the frame 1 is formed. The opening width of the space V2 is smaller than the diameter of the space V1. The needle support portion 30 is provided so as to cover the space V1.

The abutting portion 2 is constituted by an anti-slip rubber 20 and a rubber mounting portion 21 to which the anti-slip rubber 20 is mounted. The anti-slip rubber 20 can be in pressure contact with the circumferential surface portion C22 of the screw cap C2. The anti-slip rubber 20 is formed of an elastic material such as silicone rubber. The antiskid rubber 20 is C-shaped in plan view. As shown in fig. 6, the anti-slip rubber 20 has an engaging protrusion 20a formed in the center thereof and L-shaped engaging protrusions 20b formed at both ends thereof. Engaging

grooves

21a, 21b for engaging the engaging

projections

20a, 20b are also formed in the rubber mounting portion 21. In addition, a concave-convex portion 20c is formed on the circumferential surface of the anti-slip rubber 20, and the concave-convex portion 20c is fitted into a concave-convex portion 21c formed in the rubber mounting portion 21. The anti-slip rubber 20 may be attached to the rubber attachment portion 21 only by the above-described engaging means, but may be further firmly bonded by using a method such as adhesion.

A guide groove 10 into which the guide portion a2 of the ring a can be inserted is formed in the lower surface of the head portion B1. Two guide grooves 10 are formed to enable insertion of two guide portions a2 out of the 3 guide portions a 2. The guide groove 10 is formed in an arc of about 90 degrees, the length in the circumferential direction is slightly longer than the length of the guide portion a2, and the groove width is slightly larger than the width of the guide portion a 2. The guide groove 10 is formed at a position between the engaging protrusion 20a and the engaging portion 8.

The top surface facing portion 3 has a needle support portion 30 and is formed integrally with the frame portion 1. The frame 1 and the arm portion B2 are also integrally formed. The needle support 30 has a circular shape in plan view. The needle support portion 30 is coupled to the frame portion 1 by a coupling portion 31. As shown in fig. 5, the coupling portion 31 is located on the left side of the needle support portion 30, i.e., on the opposite side of the arm portion B2. The coupling portion 31 couples the needle support 30 within an angular range of about 90 degrees. In this way, an arc-shaped groove 32 is formed between the needle support portion 30 and the frame portion 1. Since the groove 32 is formed, the pair of arm portions B2 are easily elastically deformed, and the operation in the closing direction is easy.

As shown in fig. 3, the needle support portion 30 has a cylindrical portion 33 at the center, and engagement claws 34 are formed at 3 positions on the circumferential surface of the cylindrical portion 33. The engagement claw 34 is provided for coupling with the cap 7 (corresponding to a needle fixing portion). In addition, a standing wall portion 35 is formed on the outermost periphery of the needle support portion 30.

The needle portion 6 is formed as a tubular member, and a through hole is formed inside the needle portion 6. The needle portion 6 is formed of metal such as stainless steel. The distal end portion 60 of the needle portion 6 is sharpened so as to easily pierce the top surface portion C21 of the screw cap C2. The needle portion 6 is fixed to the cover 7 at a fixing portion 61 on the side opposite to the distal end portion 60. A groove is formed in the fixing portion 61 along the circumferential direction.

The needle hub 4 is a member that is fitted over the needle portion 6 to prevent a user from inadvertently touching the tip of the needle portion 6. A guide hole 40 for guiding the needle portion 6 is formed in the central portion of the needle hub 4. The cap 4 is formed in a cap shape as a whole, and has a flange portion 41. The cap 4 is inserted into the cylindrical portion 33 of the needle support portion 30 so as to be slidable vertically. A step-off preventing portion 36 is formed at an end of the cylindrical portion 33, and the inner diameter of the step-off preventing portion 36 is slightly smaller than the inner diameter of the cylindrical portion 33. Since the flange portion 41 of the cap 4 has an outer diameter larger than the inner diameter of the stepped drop preventing portion 36, the cap 4 is prevented from dropping downward by the stepped drop preventing portion 36.

A first through hole 70 and a second through hole 71 are formed in the center of the cover 7. The inner diameter of the first through-hole 70 is larger than the inner diameter of the second through-hole 71. The fixing portion 61 of the needle portion 6 is press-fitted into the first through-hole 70, whereby the needle portion 6 is fixed to the first through-hole 70. The first through-hole 70 and the second through-hole 71 having different diameters are formed to form a step, and the step can function as a stopper when the needle portion 6 is pushed in by being pressed.

The cap return spring 5 is a compression coil spring, and urges the cap 4 in a direction in which the cap is always projected, that is, in a direction in which the needle portion 6 is fitted. One end of the cap return spring 5 is inserted into the internal space of the cap 4, and the other end is attached to the spring attachment step 37.

The cover 7 has a top surface portion 72 and a peripheral surface portion 73. A second through hole 71 is formed in the center of the top surface portion 72. A fitting standing wall portion 74 is formed on the inner diameter side of the cover 7 at a position below the circumferential surface portion 73. The fitting standing wall portion 74 is fitted to the inner diameter side of the standing wall portion 35 of the needle support portion 30.

As shown in fig. 4, engaging pieces 75 are formed at 3 positions inside the cover 7. The engaging piece 75 is a thin piece that extends perpendicularly from the back side of the top surface portion 72 of the lid 7, and the engaging piece 75 is easily elastically deformed. Each of the engaging pieces 75 has an engaging hole 75a, and the engaging hole 75a engages with the engaging claw 34 of the needle support 30. With this structure, the cap 7 is not detached from the needle support portion 30.

Engaging portions 8 are integrally formed at two positions on the back surface side of the frame 1. The engaging portion 8 has an engaging claw 80, and the engaging claw 80 can be inserted into a lower portion of the flange portion a12 of the ring a. When the pair of arm portions B2 is closed, the pair of engaging portions 8 also move inward and enter the lower portion of the flange portion a12 of the ring a.

< method of using lid opener >

Hereinafter, a method of using the cap opener of the present invention will be described. When the user of the cap opener B (see fig. 1 and the like) attempts to remove the screw cap C2, as shown in fig. 9, first, the head B1 is disposed above the ring a and the screw cap C2.

Then, as shown in fig. 10, the lower end portion of the abutment portion 2 is inserted into the space V3 between the guide portion a2 and the cap C2. When the contact portion 2 protrudes into the space V3, the distal end portion 60 of the needle portion 6 is positioned at a substantially central portion of the screw cap C2, and the lateral movement of the head portion B1 is restricted. At this time, the needle portion 6 is in a state of being covered by the cap 4. Further, the contact portion 2 is in a state of extending halfway into the space V3. Further, the upper end portions of two guide portions a2 of the three guide portions a2 of the ring a are in a state of protruding into the guide groove 10 formed in the head portion B1. The upper end of the remaining one guide portion a2 is in a state of being inserted into the space V2, and the space V2 is located at the open position of the C-shaped frame 1.

The user then applies a downward force to head B1. When the user applies a downward force to the head B1, as shown in fig. 11, the tip end portion 60 of the needle portion 6 penetrates the top surface portion C21, and the head B1 moves downward. When the user moves the head B1 downward, the contact portion 2 is inserted between the guide portion a2 and the screw cap C2, and most of the guide portion a2 is inserted into the guide groove 10. At this time, the cap 4 moves upward against the urging force of the cap return spring 5, and is accommodated in the inner diameter side of the cylindrical portion 33.

When the needle portion 6 penetrates the top surface portion C21, the gas in the container C1 is released to the outside through the inside of the needle portion 6 and the second through hole 71, and the internal pressure of the container C1 is reduced.

When the internal pressure of the container C1 is released, the user grasps the pair of arm portions B2 shown in fig. 1 and brings them closer together, thereby reducing the diameter of the frame portion 1 (arrow D). When the diameter of the frame 1 is reduced by the grip of the user, the diameter of the contact portion 2 is reduced as the diameter of the frame 1 is reduced, and as shown in fig. 11, the surface of the anti-slip rubber 20 of the contact portion 2 is in pressure contact with the circumferential surface portion C22 of the screw cap C2.

Further, the diameter of the frame 1 provided with the engaging portion 8 is also reduced (arrow E in fig. 11). Therefore, the engagement claws 80 of the engagement portion 8 approach the cylindrical portion a11 of the ring a and further extend into the lower side of the flange portion a 12.

Then, the user rotates the pair of arm portions B2 about the screw cap C2 while maintaining the state in which the contact portion 2 is in pressure contact with the circumferential surface portion C22, and applies a rotational moment to the screw cap C2 via the contact portion 2. Further, while maintaining the state in which the abutting portion 2 is in pressure contact with the circumferential surface portion C22, the user continues to grip the pair of arm portions B2 shown in fig. 1. Alternatively, if the pair of arm portions B2 are locked in a state of being close to each other by a lock member (not shown), the operability can be further improved.

When a rotational torque of a predetermined value or more is applied to the screw cap C2, the screw cap C2 is loosely fastened, so that the user can easily remove the screw cap C2 from the container C1 as shown in fig. 13. Further, since a rotational torque is applied in a state where the engaging claws 80 engage with the ring a, the ring a can be removed together with the screw cap C2. Therefore, the screw cap C2 and the ring A can be removed simultaneously by one operation, which is very convenient.

< other embodiment >

The configuration of the abutting portion 2 is described as the configuration in which the anti-slip rubber 20 is provided, but the anti-slip rubber 20 is not necessarily provided. In addition to the provision of the anti-slip rubber 20, the surface may be formed into a concave-convex shape, or surface treatment for anti-slip may be performed.

In the present embodiment, the structure in which the abutting portion 2 is in pressure contact with the screw cap C2 has been described, but an engaging structure may be adopted. For example, the abutment portion 2 may be formed with an engagement portion that engages with a concave-convex portion of a thread formed on the circumferential surface portion C22.
