Description

本発明は、アイスクリームやヨーグルト等の粘稠性材料を収容する使い捨て容器にコンパクトに短縮した状態で付属させることが可能な伸縮式スプーンに関する。   The present invention relates to a telescopic spoon that can be attached to a disposable container containing a viscous material such as ice cream or yogurt in a compactly shortened state.

伸縮式スプーンとしては、例えば柄の部分を単に伸縮自在に構成したものが知られている(例えば、特許文献1、2)。   As an expandable spoon, for example, a handle in which a handle portion is simply stretchable is known (for example, Patent Documents 1 and 2).

しかし、上記伸縮式スプーンにおいては、深底の容器内から粉末状のコーヒー等を単にすくい出す際に用いるものであり、短縮した状態や伸長した状態に確実に保持する構造のものではない。   However, the telescopic spoon is used for simply scooping out powdered coffee or the like from the inside of a deep-bottomed container, and does not have a structure that reliably holds it in a shortened or elongated state.

このため、アイスクリーム等の容器にコンパクトなものとして付属させることが可能であったとしても、短縮した状態や伸長した状態に確実に保持することができず、例えばヨーグルトのような比較的柔らかなものをすくうときでも柄の長さが定まらず、使いにくいという問題がある。   For this reason, even if it can be attached to a container such as ice cream as a compact one, it cannot be reliably held in a shortened state or in an extended state, and is relatively soft such as yogurt. There is a problem that even when scooping things, the length of the handle is not fixed and it is difficult to use.

一方、短縮した状態や伸長した状態に確実に保持する機構を付加した場合には、その機構により伸縮式スプーンが複雑な構造のものとなり、短縮時のコンパクト性も失われてしまうという問題がある。   On the other hand, when a mechanism for securely holding in a shortened state or in an extended state is added, there is a problem that the retractable spoon becomes a complicated structure due to the mechanism and the compactness at the time of shortening is lost. .

請求項3に記載の発明は、請求項1又は2に記載の発明において、前記基礎軸部及び筒状軸部は、断面が円形状、楕円形状、長円形状又は多角形状に形成されていることを特徴としている。   The invention according to claim 3 is the invention according to claim 1 or 2, wherein the basic shaft portion and the cylindrical shaft portion are formed in a circular shape, an elliptical shape, an oval shape or a polygonal shape in cross section. It is characterized by that.

請求項4に記載の発明は、請求項1〜3の何れかに記載の発明において、前記皿部、基礎軸部及び筒状軸部は、プラスチックで形成されていることを特徴としている。   According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, the dish portion, the base shaft portion and the cylindrical shaft portion are made of plastic.

請求項1に記載の発明によれば、基礎軸部の先端部に設けた短縮維持ストッパ部に筒状軸部の係止部を係止させることにより、柄部を短縮状態に確実に維持することができる。また、基礎軸部の基端部に設けた伸長維持ストッパ部に筒状軸部の係止部を係止させることにより、柄部を伸長状態に確実に維持することができる。   According to the first aspect of the present invention, the handle portion is securely maintained in the shortened state by locking the locking portion of the cylindrical shaft portion to the shortening maintaining stopper portion provided at the distal end portion of the base shaft portion. be able to. Moreover, a handle | steering-piece part can be reliably maintained in an expansion | extension state by making the extension maintenance stopper part provided in the base end part of the base shaft part latch the latching part of a cylindrical shaft part.

一方、突起部によって、基礎軸部の外周面と筒状軸部の内周面との間に所定の間隔を保持した状態にすることができるので、例えば筒状軸部の外周面における周方向に180°間隔をおいた部位を互いに近づける方向に指で押圧することにより、当該筒状軸部における押圧部分の径方向の寸法を狭める方向に変位させることができると共に、押圧部分に対して周方向の一方及び他方の側に90°離れた各部分の径方向の寸法を拡大する方向に変位させることができる。この場合、筒状軸部における押圧部分の内周面が基礎軸部の外周面に達するまでは、当該筒状軸部のみに弾性変位を生じさせることができる。   On the other hand, since the projection portion can maintain a predetermined distance between the outer peripheral surface of the basic shaft portion and the inner peripheral surface of the cylindrical shaft portion, for example, the circumferential direction on the outer peripheral surface of the cylindrical shaft portion By pressing the parts spaced apart by 180 ° with a finger in a direction to bring them closer together, it is possible to displace the radial dimension of the pressing part in the cylindrical shaft part in a narrowing direction and It is possible to displace the radial dimension of each part 90 ° away from one and the other side of the direction in the direction of enlarging. In this case, until the inner peripheral surface of the pressing portion in the cylindrical shaft portion reaches the outer peripheral surface of the basic shaft portion, only the cylindrical shaft portion can be elastically displaced.

従って、筒状軸部における係止部に対して周方向の一方及び他方の側に90°離れた各部分を指で押すだけで、当該係止部を短縮維持ストッパ部又は伸長維持ストッパ部から離れる方向に変位させることができる。これにより、短縮状態及び伸長状態を簡単に解除することができる。   Therefore, by simply pressing each of the portions 90 ° apart on the one and the other side in the circumferential direction with respect to the locking portion in the cylindrical shaft portion with the finger, the locking portion is removed from the shortening maintenance stopper portion or the extension maintenance stopper portion. It can be displaced away. Thereby, the shortened state and the extended state can be easily released.

It will not be damaged. In addition, there is an advantage that a low-priced product can be provided.

また、突起部によって基礎軸部の外周面と筒状軸部の内周面との間に所定の隙間が生じることになるので、基礎軸部と筒状軸部との接触面積の低減を図ることができ、基礎軸部に対する筒状軸部の伸縮移動をスムーズに行うことができるという利点もある。   In addition, since a predetermined gap is generated between the outer peripheral surface of the basic shaft portion and the inner peripheral surface of the cylindrical shaft portion by the protrusion, the contact area between the basic shaft portion and the cylindrical shaft portion is reduced. There is also an advantage that the cylindrical shaft portion can be smoothly expanded and contracted with respect to the basic shaft portion.

請求項2に記載の発明によれば、基礎軸部が中実状の棒状に形成されている場合には、皿部と一体的に形成された基礎軸部を例えばプラスチックにより容易に成形することができる。また、基礎軸部が中空状の筒状に形成されている場合には強度の低下を抑えながら軽量化を図ることができるという利点がある。   According to the second aspect of the present invention, when the base shaft portion is formed in a solid bar shape, the base shaft portion formed integrally with the dish portion can be easily formed from, for example, plastic. it can. Further, when the base shaft portion is formed in a hollow cylindrical shape, there is an advantage that weight reduction can be achieved while suppressing a decrease in strength.

請求項3に記載の発明によれば、基礎軸部及び筒状軸部の断面が円形状に形成されている場合には径の4乗に比例する断面二次モーメントを得ることができるので、種々の方向の曲げモーメントに対して曲げ剛性の高い柄部を得ることができる。また、基礎軸部及び筒状軸部の断面が楕円形状又は長円形状に形成されている場合には、柄部を皿部に沿うような薄い形状のコンパクトなものに構成することができる。更に、三角形状や四角形状の多角形状に形成した場合もコンパクトなものにすることができる。また、五角形状以上の多角形状に形成した場合は、断面が円に近い形状になるので、柄部について曲げ剛性の高いものを提供することができる。   According to the invention described in claim 3, when the cross section of the basic shaft portion and the cylindrical shaft portion is formed in a circular shape, it is possible to obtain a cross-sectional second moment proportional to the fourth power of the diameter, A handle having high bending rigidity can be obtained with respect to bending moments in various directions. Moreover, when the cross section of the basic shaft portion and the cylindrical shaft portion is formed in an elliptical shape or an oval shape, the handle portion can be formed into a thin and compact shape that follows the plate portion. Furthermore, it can be made compact when formed into a triangular or quadrangular polygonal shape. Moreover, when it forms in the polygonal shape more than a pentagon shape, since a cross section becomes a shape close | similar to a circle | round | yen, what has high bending rigidity can be provided about a handle | pattern part.

請求項4に記載の発明によれば、皿部、基礎軸部及び筒状軸部がプラスチックで形成されているので、所定の強度を有し、かつ低価格なものを大量に提供することができる。また、筒状軸部の弾性変形代を大きくとることが可能になるので、短縮状態及び伸長状態の維持及び解除をより確実に行うことができる。   According to the invention described in claim 4, since the dish portion, the base shaft portion, and the cylindrical shaft portion are formed of plastic, it is possible to provide a large amount of low-priced products having a predetermined strength. it can. Moreover, since it becomes possible to make large the elastic deformation allowance of a cylindrical axial part, a shortened state and an expansion | extension state can be maintained and cancelled | released more reliably.

なお、基礎軸部4の先端部及び基端部と、筒状軸部5の先端部及び基端部とは、短縮状態において、軸方向の同一部位に位置するようになっている。   In addition, the front-end | tip part and base end part of the basic shaft part 4, and the front-end | tip part and base end part of the cylindrical shaft part 5 are located in the same site | part of an axial direction in a shortened state.

更に、筒状軸部5の基端部の内周面には、短縮状態において、伸長維持ストッパ部4bに係止する補助係止部5bが設けられている。なお、筒状軸部5は、補助係止部5bを備えたものでなくてもよい。   Furthermore, the inner peripheral surface of the base end portion of the cylindrical shaft portion 5 is provided with an auxiliary locking portion 5b that locks to the extension maintaining stopper portion 4b in the shortened state. Note that the cylindrical shaft portion 5 may not be provided with the auxiliary locking portion 5b.

短縮維持ストッパ部4a及び伸長維持ストッパ部4bは、基礎軸部4の外周面から凹状に形成されたものであり、基礎軸部4の軸方向に直交する方向に延在する断面V字状の溝状のもので形成されている。これらの短縮維持ストッパ部4a及び伸長維持ストッパ部4bについては、基礎軸部4における周方向に180°間隔をおいた2か所の位置であって、図2(a)に示すように、皿部2を正面視した状態において、幅方向の両側に位置するように配置されている。なお、短縮維持ストッパ部4a及び伸長維持ストッパ部4bは、皿部2の正面側とその裏面側等の周方向に180°離れた位置に配置されていてもよい。   The shortening maintaining stopper portion 4a and the extension maintaining stopper portion 4b are formed in a concave shape from the outer peripheral surface of the base shaft portion 4, and have a V-shaped cross section extending in a direction orthogonal to the axial direction of the base shaft portion 4. It is formed in a groove shape. About these shortening maintenance stopper parts 4a and extension maintenance stopper parts 4b, they are two positions spaced apart by 180 ° in the circumferential direction of the base shaft part 4, and as shown in FIG. When the part 2 is viewed from the front, it is arranged so as to be located on both sides in the width direction. In addition, the shortening maintenance stopper part 4a and the extension maintenance stopper part 4b may be arrange | positioned in the position 180 degree apart in circumferential directions, such as the front side of the plate part 2, and the back surface side.

係止部5a及び補助係止部5bは、筒状軸部5の内周面から突出するように形成されたV字状の凸状の断面形状を有し、短縮維持ストッパ部4a及び伸長維持ストッパ部4bのそれぞれに嵌り込むように、筒状軸部5の軸方向に直交する方向に延在する凸条状のもので形成されている。これらの係止部5a及び補助係止部5bは、筒状軸部5における周方向に180°間隔をおいた各位置であって、この例では周方向に180°間隔をおいて設けられた各突起部51に対応する位置に配置されている。なお、係止部5a及び補助係止部5bについては、周方向に90°の間隔をおいて隣接する突起部51の間の中央部に配置してもよい。   The locking part 5a and the auxiliary locking part 5b have a V-shaped convex cross-sectional shape formed so as to protrude from the inner peripheral surface of the cylindrical shaft part 5, and the shortening maintaining stopper part 4a and the extension maintaining part It is formed of a convex shape extending in a direction orthogonal to the axial direction of the cylindrical shaft portion 5 so as to be fitted into each of the stopper portions 4b. These locking portions 5a and auxiliary locking portions 5b are located at 180 ° intervals in the circumferential direction of the cylindrical shaft portion 5, and are provided at 180 ° intervals in the circumferential direction in this example.

In this case, the auxiliary locking portion 5b of the cylindrical shaft portion 5 is locked to the extension maintaining stopper portion 4b of the basic shaft portion 4, and the handle portion 3 can be maintained in a shortened state. Further, by locking the locking portion 5a of the cylindrical shaft portion 5 with the extension maintaining stopper portion 4b of the basic shaft portion 4, the handle portion 3 can be reliably maintained in the extended state.

一方、突起部51によって、基礎軸部4の外周面と筒状軸部5の内周面との間に所定の間隔を保持した状態にすることができるので、図3に示すように、筒状軸部5の外周面における周方向に180°間隔をおいた部位を互いに近づける方向に指でつまむようにして所定の押圧力Fを作用させることにより、当該筒状軸部5における押圧部分5c、5cの径方向の寸法を狭める方向に変位させることができると共に、押圧部分5c、5cに対して周方向の一方及び他方の側に90°離れた各部分の径方向の寸法を拡大する方向に変位させることができる。   On the other hand, since the projection 51 can maintain a predetermined distance between the outer peripheral surface of the basic shaft portion 4 and the inner peripheral surface of the cylindrical shaft portion 5, as shown in FIG. By applying a predetermined pressing force F so as to pinch the parts spaced apart by 180 ° in the circumferential direction on the outer peripheral surface of the cylindrical shaft portion 5 with fingers, the pressing portions 5c and 5c in the cylindrical shaft portion 5 are applied. Can be displaced in the direction of narrowing the radial dimension, and in the direction of enlarging the radial dimension of each part 90 ° away from the pressing parts 5c, 5c on one and the other sides in the circumferential direction. Can be made.

この場合、筒状軸部5における押圧部分5c、5cの内周面が基礎軸部4の外周面に達するまでは、当該筒状軸部5のみを変位させることができる。   In this case, only the cylindrical shaft portion 5 can be displaced until the inner peripheral surface of the pressing portions 5 c and 5 c in the cylindrical shaft portion 5 reaches the outer peripheral surface of the basic shaft portion 4.

従って、筒状軸部5における係止部5aに対して周方向の一方及び他方の側に90°離れた各部分を押圧部分5c、5cとし、この押圧部分5c、5cを指で押すことにより、当該係止部5aを短縮維持ストッパ部4a又は伸長維持ストッパ部4bから離れる方向に変位させることができる。即ち、短縮状態及び伸長状態を簡単に解除することができる。   Accordingly, the portions which are 90 ° apart from each other in the circumferential direction with respect to the locking portion 5a in the cylindrical shaft portion 5 are set as the pressing portions 5c and 5c, and the pressing portions 5c and 5c are pressed by a finger. The locking portion 5a can be displaced in a direction away from the shortening maintaining stopper portion 4a or the extension maintaining stopper portion 4b. That is, the shortened state and the extended state can be easily released.

そして、短縮状態及び伸長状態の維持及び解除を、突起部51、短縮維持ストッパ部4a、伸長維持ストッパ部4b及び係止部5aによって行うことができるので、構造が複雑になることも、短縮時にコンパクト性が失われることもない。即ち、伸縮式スプーン1は、図1(a)に示すように、短縮状態にすることで極めてコンパクトにすることができるので、透明袋Bに挿入してアイスクリーム等の容器Aの蓋部又は底部に貼り付けることができる。   Further, the maintenance and release of the shortened state and the extended state can be performed by the protrusion 51, the shortened maintenance stopper portion 4a, the extension maintenance stopper portion 4b, and the locking portion 5a. The compactness is not lost. That is, as shown in FIG. 1 (a), the telescopic spoon 1 can be made extremely compact by being shortened, so that it can be inserted into the transparent bag B and the lid portion of the container A such as ice cream or the like. Can be attached to the bottom.

また、補助係止部5bを設けることにより、短縮状態における基礎軸部4と筒状軸部5との連結強度を高めることができるので、開封直後の硬い状態にある例えばアイスクリームに対しても、伸縮式スプーン1を短縮状態で使用することにより容易にすくい取ることが可能になる。   Moreover, since the connection strength of the basic shaft part 4 and the cylindrical shaft part 5 in the shortened state can be increased by providing the auxiliary latching part 5b, for example for ice cream in a hard state immediately after opening By using the telescopic spoon 1 in a shortened state, it can be easily scooped.

一方、突起部51によって基礎軸部4の外周面と筒状軸部5の内周面との間に所定の隙間が生じることになるので、基礎軸部4と筒状軸部5との接触面積の低減を図ることができ、基礎軸部4に対する筒状軸部5の伸縮移動をスムーズに行うことができるという利点もある。   On the other hand, since a predetermined gap is generated between the outer peripheral surface of the basic shaft portion 4 and the inner peripheral surface of the cylindrical shaft portion 5 by the protrusion 51, the contact between the basic shaft portion 4 and the cylindrical shaft portion 5 is made. There is an advantage that the area can be reduced and the cylindrical shaft portion 5 can be smoothly expanded and contracted with respect to the basic shaft portion 4.

更に、基礎軸部4及び筒状軸部5が断面円形状の筒状(中空状)に形成されているので、径の4乗に比例する断面二次モーメントを得ることができ、柄部3について曲げ剛性の高いものを得ることができると共に、筒状の中空形状とすることにより軽量化、材料の節減、これによるコストの低減等を図ることができる。   Furthermore, since the basic shaft portion 4 and the cylindrical shaft portion 5 are formed in a cylindrical shape (hollow shape) having a circular cross section, a second moment of section proportional to the fourth power of the diameter can be obtained, and the handle portion 3 In addition to being able to obtain a material having a high bending rigidity, it is possible to achieve weight reduction, material saving, cost reduction, and the like by adopting a cylindrical hollow shape.

しかも、皿部2、基礎軸部4及び筒状軸部5がプラスチックで形成されているので、所定の強度を有する低価格なものを大量に提供することができる。特に、皿部2と基礎軸部4をプラスチックにより一体化し強度の高いものを得ることができる。また、プラスチックによる大きな弾性変形に基づいて、短縮状態及び伸長状態の維持及び解除を確実に行うことができる。   In addition, since the dish part 2, the base shaft part 4, and the cylindrical shaft part 5 are formed of plastic, it is possible to provide a large amount of inexpensive products having a predetermined strength. In particular, the plate portion 2 and the base shaft portion 4 can be integrated with plastic to obtain a high strength one. Further, the shortened state and the extended state can be reliably maintained and released based on the large elastic deformation caused by the plastic.

なお、上記実施形態においては、突起部51を筒状軸部5の内周面に形成した例を示したが、この突起部51については、基礎軸部4の外周面における先端部及び基端部を除く部分に形成してもよい。この場合、短縮維持ストッパ部4a、伸長維持ストッパ部4b、係止部5a、補助係止部5bについては、隣接する突起部51の間に対応する位置に配置することが好ましい。また、突起部51については、基礎軸部4の外周面及び筒状軸部5の内周面の双方に設けてもよい。この場合、例えば基礎軸部4の突起部51を挟むように、筒状軸部5の突起部51を設けることにより、基礎軸部4の軸回りに筒状軸部5が回るのを防止することができる。更に、突起部51については、筒状軸部5の内周面や基礎軸部4の外周面において軸方向に所定の間隔をおいて所定の部位から突出するように形成したものであってもよい。   In the above-described embodiment, the example in which the protrusion 51 is formed on the inner peripheral surface of the cylindrical shaft portion 5 has been described. However, the protrusion 51 has a distal end portion and a proximal end on the outer peripheral surface of the base shaft portion 4. You may form in the part except a part. In this case, the shortening maintaining stopper portion 4a, the extension maintaining stopper portion 4b, the locking portion 5a, and the auxiliary locking portion 5b are preferably arranged at corresponding positions between the adjacent protruding portions 51. Further, the protrusion 51 may be provided on both the outer peripheral surface of the basic shaft portion 4 and the inner peripheral surface of the cylindrical shaft portion 5. In this case, for example, by providing the protruding portion 51 of the cylindrical shaft portion 5 so as to sandwich the protruding portion 51 of the basic shaft portion 4, the cylindrical shaft portion 5 is prevented from turning around the axis of the basic shaft portion 4. be able to. Further, the protrusion 51 may be formed so as to protrude from a predetermined portion at a predetermined interval in the axial direction on the inner peripheral surface of the cylindrical shaft portion 5 or the outer peripheral surface of the basic shaft portion 4. Good.

また、基礎軸部4及び筒状軸部5として断面円形状の筒状のものを示したが、これらの基礎軸部4及び筒状軸部5については、図4に示すように、断面が楕円形状や長円形状の筒状に形成したものであってもよい。なお、図4においては、上述した構成に対応する構成について同一の符号を付して示している。このように基礎軸部4及び筒状軸部5を楕円形状又は長円形状の筒状に形成した場合には、柄部3を皿部2に沿うような薄い形状のもので構成することができ、よりコンパクトなものを得ることができる。   Moreover, although the cylindrical thing of the cross-section circular shape was shown as the basic shaft part 4 and the cylindrical shaft part 5, about the basic shaft part 4 and the cylindrical shaft part 5, as shown in FIG. It may be formed in an elliptical or oval cylindrical shape. In FIG. 4, the components corresponding to the above-described components are denoted by the same reference numerals. Thus, when the basic shaft part 4 and the cylindrical shaft part 5 are formed in an elliptical shape or an elliptical cylindrical shape, the handle part 3 may be configured with a thin shape along the dish part 2. And a more compact one can be obtained.

更に、基礎軸部4及び筒状軸部5については、図5に示すように、断面が長四角形状(長方形状)の筒状に形成したものであってもよい。なお、図5においては、上述した構成に対応する構成について同一の符号を付して示している。このように基礎軸部4及び筒状軸部5の断面を長四角形状の筒状に形成した場合にも、柄部3を皿部2に沿うような薄い形状のもので構成することができ、よりコンパクトなものにすることができる。   Furthermore, as shown in FIG. 5, the basic shaft portion 4 and the cylindrical shaft portion 5 may be formed in a cylindrical shape having a long quadrangular cross section (rectangular shape). In FIG. 5, the same reference numerals are given to the components corresponding to the above-described components. Thus, even when the cross sections of the base shaft portion 4 and the cylindrical shaft portion 5 are formed in a long rectangular shape, the handle portion 3 can be configured with a thin shape along the plate portion 2. Can be made more compact.

更にまた、基礎軸部4及び筒状軸部5については、図示を省略するが、断面が3角形以上の多角形の筒状に形成したものであってもよい。三角形状や上記四角形状の多角形状に形成した場合は上述のようにコンパクトなものを得ることができる。また、五角形状以上の多角形状に形成した場合は、断面が円に近い形状になり、柄部3について曲げ剛性の高いものを提供することができる。   Furthermore, although illustration is abbreviate | omitted about the basic | foundation axial part 4 and the cylindrical axial part 5, the cross section may form in the polygonal cylindrical shape more than a triangle. When it is formed in a triangular shape or a quadrangular polygonal shape, a compact one can be obtained as described above. Moreover, when it forms in polygonal shape more than a pentagon shape, a cross section becomes a shape close | similar to a circle | round | yen, and what has high bending rigidity about the handle | pattern part 3 can be provided.

また、上述した説明では基礎軸部4を筒状のもので構成した例を示したが、この基礎軸部4としては、上述した種々の断面形状のもので中実状の棒状に形成したものであってもよい。基礎軸部4を中実の棒状に形成した場合には、皿部2と一体のものをプラスチックで容易に成形することができる利点がある。   Moreover, although the example which comprised the basic | foundation axial part 4 by the cylindrical thing was shown in the description mentioned above, as this basic | foundation axial part 4, it was what was formed in the shape of a solid rod with the various cross-sectional shapes mentioned above. There may be. In the case where the base shaft portion 4 is formed in a solid bar shape, there is an advantage that the one integrated with the plate portion 2 can be easily molded with plastic.
