Description

本発明は、容器に関する。 The present invention relates to containers.

特許文献１には、内容物が収容される有底筒状の本体部材の下端部に、底部材を取り付けた容器が開示されている。 Patent Literature 1 discloses a container in which a bottom member is attached to the lower end of a bottomed cylindrical main body member in which contents are stored.

実開平６－５７８０９号公報Japanese Utility Model Laid-Open No. 6-57809

特許文献１の構成では、底部材が本体部材の下端部を外側から覆っているため、本体部材の側面が一部視認しにくくなっている。そこで、本体部材を外側から覆わずに、底部材を本体部材に取り付け可能な構成が求められていた。 In the configuration of Patent Document 1, since the bottom member covers the lower end of the body member from the outside, it is difficult to see part of the side surface of the body member. Therefore, there has been a demand for a configuration in which the bottom member can be attached to the body member without covering the body member from the outside.

本発明はこのような事情を考慮してなされ、本体部材を外側から覆わずに、底部材を本体部材に取り付け可能な容器を提供することを目的とする。 SUMMARY OF THE INVENTION It is an object of the present invention to provide a container in which a bottom member can be attached to a body member without covering the body member from the outside.

上記課題を解決するために、本発明の一態様に係る容器は、内容物が収容される有底筒状の本体部材と、前記本体部材の下端部に取り付けられた底部材と、を備え、前記本体部材の底部には、上方に向けて窪む凹部が形成され、前記底部材には、前記凹部内に挿入された凸部と、前記凹部の内周面に対して弾性変形した状態で当接した爪部と、が形成されている。 In order to solve the above problems, a container according to an aspect of the present invention includes a bottomed cylindrical main body member in which contents are accommodated, and a bottom member attached to the lower end of the main body member, The bottom of the body member is formed with a concave portion that is recessed upward, and the bottom member includes a convex portion inserted into the concave portion and an elastically deformed state with respect to the inner peripheral surface of the concave portion. A pawl portion that abuts is formed.

上記態様によれば、容器の用途などに合わせて、異なる種類の底部材と本体部材とを組み合わせることができる。そして、底部材の凸部が本体部材の凹部内に挿入される構成であるため、本体部材を外側から覆わずに底部材を本体部材に取り付けることができる。さらに、爪部が凹部の内周面に対して弾性変形した状態で当接しているため、底部材が本体部材から不意に脱落することを抑制することができる。 According to the above aspect, different types of bottom members and body members can be combined according to the use of the container. Further, since the protrusions of the bottom member are inserted into the recesses of the body member, the bottom member can be attached to the body member without covering the body member from the outside. Furthermore, since the claw portion abuts against the inner peripheral surface of the recess while being elastically deformed, it is possible to prevent the bottom member from unexpectedly falling off from the main body member.

ここで、前記本体部材は、本体筒部と、前記本体筒部の下端部から径方向内側に向けて延びるヒール部と、前記ヒール部と前記凹部とを接続するガイド部と、を有し、前記ガイド部は、径方向内側に向かうに従って漸次上方に向けて傾斜していてもよい。 Here, the main body member has a main tubular portion, a heel portion extending radially inward from a lower end portion of the main tubular portion, and a guide portion connecting the heel portion and the concave portion, The guide portion may be gradually inclined upward as it goes radially inward.

この場合、底部材を本体部材に取り付ける前の状態において、爪部が凹部の内周面に干渉する寸法関係になっていたとしても、爪部とガイド部とを摺動させることで、スムーズに凸部および爪部を凹部内に導入することができる。したがって、底部材を本体部材に取り付ける際の作業効率を向上させることができる。 In this case, even if the claw portion interferes with the inner peripheral surface of the recess before the bottom member is attached to the main body member, the claw portion and the guide portion can be slid smoothly. The protrusions and claws can be introduced into the recesses. Therefore, it is possible to improve work efficiency when attaching the bottom member to the body member.

また、前記凸部の外周面には、径方向外側に向けて突出し、かつ上下方向に延びる縦リブが、周方向に間隔を空けて複数形成されていてもよい。 Further, a plurality of longitudinal ribs projecting radially outward and extending vertically may be formed at intervals in the circumferential direction on the outer peripheral surface of the convex portion.

この場合、凸部の外周面と凹部の内周面との接触面積が小さくなるため、よりスムーズに凸部を凹部内に挿入することができる。さらに、成形後の本体部材の凹部内に多少寸法バラツキがあったとしても、凸部を凹部内に挿入可能とすることができる。 In this case, since the contact area between the outer peripheral surface of the protrusion and the inner peripheral surface of the recess is small, the protrusion can be inserted into the recess more smoothly. Furthermore, even if there is some dimensional variation in the recess of the body member after molding, the projection can be inserted into the recess.

また、前記爪部は、前記凸部を上下方向に貫通する貫通孔の輪郭に沿って形成されており、前記爪部は前記凸部の頂壁における中央部から径方向外側に向けて延びていてもよい。 In addition, the claw portion is formed along the contour of a through-hole vertically penetrating the convex portion, and the claw portion extends radially outward from the central portion of the top wall of the convex portion. may

この場合、凸部を凹部内に挿入する際に、爪部を下方に向けて弾性変形させることができる。底部材を本体部材に取り付けたあと、底部材を本体部材から下方に抜き取ろうとすると、爪部と凹部の内周面との間に作用する摩擦力により、爪部は上方に復元変形しようとする。しかしながらこのような変形は、爪部が凹部の内周面に突き当たっていることで規制されるため、結果として、底部材が本体部材から離脱されにくくすることができる。 In this case, when inserting the protrusion into the recess, the claw can be elastically deformed downward. After the bottom member is attached to the main body member, when the bottom member is pulled out downward from the main body member, the claw portion tends to deform upward due to the frictional force acting between the claw portion and the inner peripheral surface of the recess. do. However, such deformation is restricted by the contact of the claw portion with the inner peripheral surface of the recess, and as a result, it is possible to make it difficult for the bottom member to separate from the main body member.

本発明の上記態様によれば、本体部材を外側から覆わずに、底部材を本体部材に取り付け可能な容器を提供することができる。 According to the aspect of the present invention, it is possible to provide a container in which the bottom member can be attached to the body member without covering the body member from the outside.

The lid member 10 is arranged coaxially with the container axis O as a whole.
The outer wall portion 11 is formed in a tubular shape extending in the vertical direction, and is fitted to the mouth portion 21a of the main body member 20 from the radially outer side. A weakened portion 11a is formed in the central portion of the outer wall portion 11 in the vertical direction. The weakened portion 11a is a slit extending in the circumferential direction, and the outer wall portion 11 can be broken along the weakened portion 11a. A fitting protrusion 11 b that protrudes radially inward is formed on the inner peripheral surface of the outer wall 11 . The fitting projection 11b is formed in an annular shape over the entire circumference of the outer wall portion 11 and is undercut-fitted to an annular projection formed on the main body member 20 . The fitting protrusions 11b may not be formed over the entire circumference, and may be intermittently formed in the circumferential direction, for example.

環状部１２は、外壁部１１の上端部から径方向内側に向けて延びており、平面視で環状に形成されている。環状部１２は、本体部材２０の上端部に上方から接している。
内壁部１３は上下方向に延びる筒状に形成されており、環状部１２の内周縁から下方に向けて延びている。内壁部１３は、本体部材２０の口部２１ａ内に嵌合している。
閉塞部１４は、内壁部１３の下端部から径方向内側に向けて延びており、平面視で円形状に形成されている。閉塞部１４により、口部２１ａが閉塞されている。
図２に示すように、操作部１５は、外壁部１１から径方向外側に向けて突出している。図１に示すように、操作部１５は、外壁部１１の弱化部１１ａに隣接しており、弱化部１１ａの上方に配置されている。 The annular portion 12 extends radially inward from the upper end portion of the outer wall portion 11 and has an annular shape in plan view. The annular portion 12 is in contact with the upper end portion of the body member 20 from above.
The inner wall portion 13 is formed in a vertically extending tubular shape and extends downward from the inner peripheral edge of the annular portion 12 . The inner wall portion 13 is fitted into the mouth portion 21 a of the main body member 20 .
The closing portion 14 extends radially inward from the lower end portion of the inner wall portion 13 and has a circular shape in plan view. The opening 21 a is closed by the closing portion 14 .
As shown in FIG. 2 , the operating portion 15 protrudes radially outward from the outer wall portion 11 . As shown in FIG. 1, the operation portion 15 is adjacent to the weakened portion 11a of the outer wall portion 11 and is arranged above the weakened portion 11a.

図３に示すように、本体部材２０は、本体筒部２１と、ヒール部２２と、凹部２３とを有している。本体筒部２１は上下方向に延びる筒状に形成されている。本体筒部２１の上端開口部が、先述の口部２１ａとされている。本体筒部２１の外周面には、径方向外側に向けて突出するネックリング２１ｂが形成されている。ネックリング２１ｂは、平面視で環状に形成されており、蓋部材１０の外壁部１１と上下方向で対向している。 As shown in FIG. 3 , the main body member 20 has a main tubular portion 21 , a heel portion 22 and a concave portion 23 . The body tubular portion 21 is formed in a tubular shape extending in the vertical direction. An upper end opening of the body tubular portion 21 is the above-mentioned mouth portion 21a. A neck ring 21 b that protrudes radially outward is formed on the outer peripheral surface of the body tubular portion 21 . The neck ring 21b has an annular shape in plan view, and faces the outer wall portion 11 of the lid member 10 in the vertical direction.

ヒール部２２は、本体筒部２１の下端部から径方向内側に向けて延びており、平面視で環状に形成されている。凹部２３は、ヒール部２２から上方に向けて窪んでおり、有頂筒状に形成されている。凹部２３の内周面２３ａは、縦断面視で直線状に形成されている。図３の例では、内周面２３ａが容器軸Ｏと平行であるが、内周面２３ａは縦断面視において容器軸Ｏに対して傾いたテーパ面であってもよい。つまり、内周面２３ａの内径は、上下方向に沿って一定でもよいし、上下方向に沿って変化していてもよい。 The heel portion 22 extends radially inward from the lower end portion of the main tubular portion 21 and has an annular shape in plan view. The recessed portion 23 is recessed upward from the heel portion 22 and is formed in a truncated tubular shape. An inner peripheral surface 23a of the recessed portion 23 is formed linearly in a vertical cross-sectional view. Although the inner peripheral surface 23a is parallel to the container axis O in the example of FIG. That is, the inner diameter of the inner peripheral surface 23a may be constant along the vertical direction, or may vary along the vertical direction.

凹部２３とヒール部２２との接続部には、ガイド部２４が形成されている。ガイド部２４は、ヒール部２２の内周縁から、径方向内側に向かうに従って上方に向かうように傾斜している。これにより、ガイド部２４の下面はテーパ面となっている。 A guide portion 24 is formed at the connecting portion between the concave portion 23 and the heel portion 22 . The guide portion 24 is inclined upward from the inner peripheral edge of the heel portion 22 as it goes radially inward. As a result, the lower surface of the guide portion 24 is tapered.

底部材３０は、凸部３１と、段部３２と、接続部３３と、袴部３４と、を有している。底部材３０の各部は、容器軸Ｏと同軸上に配置されている。
凸部３１は、段部３２から上方に向けて突出しており、本体部材２０の凹部２３内に挿入されている。凸部３１の外周面における外径は、凹部２３の内径よりも小さい。凸部３１は、上下方向に延びる有頂筒状に形成されている。段部３２は、凸部３１の下端部から径方向外側に向けて延びており、平面視で環状に形成されている。段部３２は、本体部材２０のヒール部２２およびガイド部２４と上下方向で対向している。段部３２の径方向外側の端部は、上方に向けて突出している。 The bottom member 30 has a convex portion 31 , a stepped portion 32 , a connecting portion 33 , and a skirt portion 34 . Each part of the bottom member 30 is arranged coaxially with the container axis O. As shown in FIG.
The convex portion 31 projects upward from the stepped portion 32 and is inserted into the concave portion 23 of the main body member 20 . The outer diameter of the outer peripheral surface of the convex portion 31 is smaller than the inner diameter of the concave portion 23 . The convex portion 31 is formed in a capped tubular shape extending in the vertical direction. The stepped portion 32 extends radially outward from the lower end portion of the convex portion 31 and has an annular shape in plan view. The step portion 32 vertically faces the heel portion 22 and the guide portion 24 of the body member 20 . A radially outer end of the stepped portion 32 protrudes upward.

接続部３３は、段部３２の外周縁から下方に延びる筒状に形成されており、段部３２と袴部３４とを接続している。
袴部３４は、接続部３３から下方に向かうに従って漸次拡径するテーパ筒状に形成されている。袴部３４の下端部における外径は、本体部材２０の本体筒部２１の外径よりも大きい。袴部３４は、容器１を正立姿勢（図１、図３に示す姿勢）で机上などの載置面に載置した時、載置面と接触する部分である。袴部３４により、容器１を正立姿勢で載置した時の姿勢を安定させることができる。 The connecting portion 33 is formed in a tubular shape extending downward from the outer peripheral edge of the stepped portion 32 and connects the stepped portion 32 and the skirt portion 34 .
The skirt portion 34 is formed in a tapered tubular shape whose diameter gradually increases downward from the connecting portion 33 . The outer diameter of the lower end portion of the skirt portion 34 is larger than the outer diameter of the main tubular portion 21 of the main body member 20 . The hakama portion 34 is a portion that comes into contact with a placement surface such as a desk when the container 1 is placed in an upright posture (the posture shown in FIGS. 1 and 3). The posture when the container 1 is placed in an upright posture can be stabilized by the hakama portion 34 .

図４に示すように、凸部３１には、縦リブ３１ａおよび爪部３５が形成されている。図５に示すように、縦リブ３１ａおよび爪部３５は、周方向に間隔を空けて複数（本実施形態では各３つ）形成されている。縦リブ３１ａは、凸部３１から径方向外側に向けて突出し、上下方向に延びている。 As shown in FIG. 4, the convex portion 31 is formed with a vertical rib 31a and a claw portion 35. As shown in FIG. As shown in FIG. 5, a plurality of vertical ribs 31a and claw portions 35 (three each in this embodiment) are formed at intervals in the circumferential direction. The vertical rib 31a protrudes radially outward from the convex portion 31 and extends in the vertical direction.

爪部３５は、凸部３１の頂壁における中央部から、径方向外側に向けて延びている。複数の爪部３５は、容器軸Ｏから放射状に延びている。爪部３５の径方向外側の端部は、凸部３１の外周面よりも径方向外側に位置している。このため、各爪部３５の径方向外側の端部に外接する外接円Ｃの直径は、凸部３１の外径よりも大きくなっている。また、外接円Ｃの直径は、本体部材２０の凹部２３の内径よりも大きくなっている。図４に示すように、爪部３５の径方向外側の端部には、傾斜面３５ａが形成されている。傾斜面３５ａは上方を向いており、径方向外側に向かうに従って漸次下方に向かうように延びている。 The claw portion 35 extends radially outward from the central portion of the top wall of the convex portion 31 . A plurality of claw portions 35 radially extend from the container axis O. As shown in FIG. A radially outer end portion of the claw portion 35 is positioned radially outwardly of the outer peripheral surface of the convex portion 31 . Therefore, the diameter of the circumscribed circle C that circumscribes the radially outer end of each claw portion 35 is larger than the outer diameter of the convex portion 31 . Also, the diameter of the circumscribed circle C is larger than the inner diameter of the recess 23 of the body member 20 . As shown in FIG. 4 , an inclined surface 35 a is formed at the radially outer end of the claw portion 35 . The inclined surface 35a faces upward and extends downward as it goes radially outward.

図５に示すように、底部材３０には、凸部３１および段部３２を上下方向に貫通する貫通孔３６が形成されている。平面視において、貫通孔３６は爪部３５の輪郭に沿って形成されている。貫通孔３６によって爪部３５が形成されている、ということもできる。貫通孔３６は、外孔部３６ａと、第１内孔部３６ｂと、第２内孔部３６ｃとを有している。外孔部３６ａは周方向に延びており、平面視において、爪部３５の径方向外側の端部に隣接している。第１内孔部３６ｂおよび第２内孔部３６ｃは略平行に配置されており、外孔部３６ａの端部から、それぞれ径方向内側に向けて延びている。平面視において、爪部３５は、第１内孔部３６ｂと第２内孔部３６ｃとの間に位置している。 As shown in FIG. 5, the bottom member 30 is formed with a through hole 36 that vertically penetrates the protrusion 31 and the stepped portion 32 . The through hole 36 is formed along the contour of the claw portion 35 in plan view. It can also be said that the claw portion 35 is formed by the through hole 36 . The through hole 36 has an outer hole portion 36a, a first inner hole portion 36b, and a second inner hole portion 36c. The outer hole portion 36a extends in the circumferential direction and is adjacent to the radially outer end portion of the claw portion 35 in plan view. The first inner hole portion 36b and the second inner hole portion 36c are arranged substantially parallel and extend radially inward from the end portion of the outer hole portion 36a. In plan view, the claw portion 35 is positioned between the first inner hole portion 36b and the second inner hole portion 36c.

次に、以上のように構成された容器の作用について説明する。 Next, the operation of the container constructed as above will be described.

図６（ａ）に示すように、底部材３０を本体部材２０に取り付ける際には、底部材３０と本体部材２０とを上下方向で対向させ、凸部３１を凹部２３内に挿入する。このとき、
図５の外接円Ｃの直径が凹部２３の内径よりも大きいため、爪部３５と凹部２３の内周面２３ａとが干渉する。しかしながら、爪部３５に形成された傾斜面３５ａおよび本体部材２０に形成されたガイド部２４によって、スムーズに凸部３１を凹部２３内に導入することができる。また、凸部３１には複数の縦リブ３１ａが形成されているため、凸部３１と凹部２３との接触面積が小さくなり、凸部３１を凹部２３内により挿入しやすい。 As shown in FIG. 6A , when attaching the bottom member 30 to the main body member 20 , the bottom member 30 and the main body member 20 are vertically opposed to each other, and the projections 31 are inserted into the recesses 23 . At this time,
Since the diameter of the circumscribed circle C in FIG. However, the inclined surface 35 a formed on the claw portion 35 and the guide portion 24 formed on the main body member 20 allow the convex portion 31 to be smoothly introduced into the concave portion 23 . In addition, since a plurality of vertical ribs 31a are formed on the convex portion 31, the contact area between the convex portion 31 and the concave portion 23 is reduced, making it easier to insert the convex portion 31 into the concave portion 23. FIG.

凸部３１を凹部２３内に導入し、さらに底部材３０を上方に移動させると、爪部３５は凹部２３の内周面２３ａと摺動する。このとき、爪部３５には下方に向けた摩擦力が作用するため、爪部３５は下方に向けて弾性変形する。底部材３０の段部３２と本体部材２０のヒール部２２とが当接すると、底部材３０と本体部材２０との上下方向の位置が定まり、取付作業が完了する。 When the convex portion 31 is introduced into the concave portion 23 and the bottom member 30 is moved upward, the claw portion 35 slides on the inner peripheral surface 23 a of the concave portion 23 . At this time, since downward frictional force acts on the claw portion 35, the claw portion 35 is elastically deformed downward. When the stepped portion 32 of the bottom member 30 and the heel portion 22 of the body member 20 come into contact with each other, the vertical positions of the bottom member 30 and the body member 20 are determined, and the mounting operation is completed.

底部材３０を本体部材２０に取り付けたあと、底部材３０を本体部材２０から下方に抜き取ろうとすると、爪部３５と凹部２３の内周面２３ａとの間に作用する摩擦力により、爪部３５は上方に復元変形しようとする。しかしながら、このような変形は、爪部３５が凹部２３の内周面２３ａに突き当たっていることで規制されている。結果として、底部材３０は本体部材２０から離脱されにくくなっている。 After the bottom member 30 is attached to the main body member 20, when the bottom member 30 is to be pulled downward from the main body member 20, the frictional force acting between the claw portion 35 and the inner peripheral surface 23a of the concave portion 23 causes the claw portion to move. 35 attempts to restore and deform upward. However, such deformation is restricted because the claw portion 35 abuts against the inner peripheral surface 23 a of the concave portion 23 . As a result, the bottom member 30 is difficult to separate from the main body member 20 .

以上説明したように、本実施形態の容器１は、内容物が収容される有底筒状の本体部材２０と、本体部材２０の下端部に取り付けられた底部材３０とを備えている。このため、容器１の用途などに合わせて、異なる種類の底部材３０と本体部材２０とを組み合わせることができる。そして、底部材３０の凸部３１が、本体部材２０の底部に形成された凹部２３内に挿入される構成であるため、本体筒部２１を径方向外側から覆わずに、底部材３０を本体部材２０に取り付けることができる。さらに、爪部３５が凹部２３の内周面２３ａに対して弾性変形した状態で当接しているため、底部材３０が本体部材２０から不意に脱落することを抑制することができる。 As described above, the container 1 of the present embodiment includes the bottomed cylindrical body member 20 in which contents are stored, and the bottom member 30 attached to the lower end of the body member 20 . Therefore, different types of bottom member 30 and main body member 20 can be combined according to the application of the container 1 or the like. Since the convex portion 31 of the bottom member 30 is inserted into the concave portion 23 formed in the bottom portion of the main body member 20, the bottom member 30 can be inserted into the main body without covering the main tubular portion 21 from the outside in the radial direction. It can be attached to member 20 . Furthermore, since the claw portion 35 abuts on the inner peripheral surface 23a of the recess portion 23 in an elastically deformed state, the bottom member 30 can be prevented from unexpectedly falling off from the main body member 20. As shown in FIG.

また、本体部材２０は、本体筒部２１と、本体筒部２１の下端部から径方向内側に向けて延びるヒール部２２と、ヒール部２２と凹部２３とを接続するガイド部２４と、を有し、ガイド部２４は、径方向内側に向かうに従って漸次上方に向けて傾斜している。この構成により、底部材３０を本体部材２０に取り付ける前の状態（図５または図６（ａ））において、爪部３５が凹部２３の内周面２３ａに干渉する寸法関係になっていたとしても、爪部３５とガイド部２４とを摺動させることで、スムーズに凸部３１および爪部３５を凹部２３内に導入することができる。したがって、底部材３０を本体部材２０に取り付ける際の作業効率を向上させることができる。 Further, the body member 20 has a body tubular portion 21 , a heel portion 22 extending radially inward from the lower end portion of the body tubular portion 21 , and a guide portion 24 connecting the heel portion 22 and the recessed portion 23 . However, the guide portion 24 is gradually inclined upward as it goes radially inward. With this configuration, even if the claw portion 35 interferes with the inner peripheral surface 23a of the concave portion 23 in the state before the bottom member 30 is attached to the main body member 20 (FIG. 5 or FIG. 6A), By sliding the claw portion 35 and the guide portion 24, the projection portion 31 and the claw portion 35 can be introduced into the recess portion 23 smoothly. Therefore, work efficiency when attaching the bottom member 30 to the main body member 20 can be improved.

また、凸部３１の外周面には、径方向外側に向けて突出し、かつ上下方向に延びる縦リブ３１ａが、周方向に間隔を空けて複数形成されている。この構成により、凸部３１の外周面と凹部２３の内周面２３ａとの接触面積が小さくなるため、よりスムーズに凸部３１を凹部２３内に挿入することができる。 A plurality of longitudinal ribs 31a projecting radially outward and extending in the vertical direction are formed on the outer peripheral surface of the convex portion 31 at intervals in the circumferential direction. With this configuration, the contact area between the outer peripheral surface of the protrusion 31 and the inner peripheral surface 23a of the recess 23 is reduced, so that the protrusion 31 can be inserted into the recess 23 more smoothly.

また、爪部３５は貫通孔３６の輪郭に沿って形成されており、凸部３１の頂壁における中央部から径方向外側に向けて延びている。この構成により、凸部３１を凹部２３内に挿入する際に爪部３５が下方に向けて弾性変形するため、底部材３０を本体部材２０から離脱されにくくすることができる。 The claw portion 35 is formed along the contour of the through hole 36 and extends radially outward from the central portion of the top wall of the convex portion 31 . With this configuration, when the projection 31 is inserted into the recess 23 , the claw portion 35 is elastically deformed downward, so that the bottom member 30 can be made difficult to separate from the main body member 20 .

（第２実施形態）
次に、本発明に係る第２実施形態について説明するが、第１実施形態と基本的な構成は同様である。このため、同様の構成には同一の符号を付してその説明は省略し、異なる点についてのみ説明する。 (Second embodiment)
Next, a second embodiment according to the present invention will be described, but the basic configuration is the same as that of the first embodiment. For this reason, the same reference numerals are assigned to the same configurations, the description thereof is omitted, and only the points of difference will be described.

図７に示すように、本実施形態では蓋部材１０が薄膜状に形成されている。本体部材２０の本体筒部２１は、上方に向かうに従って漸次拡径している。底部材３０には接続部３３（図３参照）が形成されておらず、袴部３４が、段部３２から下方に向けて延びている。 As shown in FIG. 7, the cover member 10 is formed in a thin film shape in this embodiment. A body tubular portion 21 of the body member 20 gradually expands in diameter as it goes upward. A connection portion 33 (see FIG. 3) is not formed in the bottom member 30, and a skirt portion 34 extends downward from the stepped portion 32. As shown in FIG.

本実施形態のようなカップ形状の容器１についても、第１実施形態と同様の作用効果を得ることができる。 With the cup-shaped container 1 as in the present embodiment, the same effects as in the first embodiment can be obtained.

なお、本発明の技術的範囲は前記実施の形態に限定されず、本発明の趣旨を逸脱しない範囲において種々の変更を加えることが可能である。 The technical scope of the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the present invention.

例えば、前記実施形態では、爪部３５が複数設けられていたが、爪部３５の数は１つであってもよい。
また、前記実施形態では、底部材３０が本体筒部２１を径方向外側から覆わない構成となっていたが、底部材３０が本体筒部２１を部分的に覆っていてもよい。 For example, in the above embodiment, a plurality of claw portions 35 are provided, but the number of claw portions 35 may be one.
Further, in the above-described embodiment, the bottom member 30 does not cover the tubular body portion 21 from the outside in the radial direction, but the bottom member 30 may partially cover the tubular body portion 21 .

また、凹部２３の内周面２３ａにも、上下方向に延びる縦リブ（ローレット）を複数形成してもよい。この場合、底部材３０が捩じられたときに、底部材３０が本体部材２０から不意に脱落することを抑制することができる。 In addition, a plurality of vertical ribs (knurls) extending in the vertical direction may be formed on the inner peripheral surface 23a of the recess 23 as well. In this case, when the bottom member 30 is twisted, it is possible to prevent the bottom member 30 from unexpectedly falling off from the body member 20 .

その他、本発明の趣旨を逸脱しない範囲で、上記した実施の形態における構成要素を周知の構成要素に置き換えることは適宜可能であり、また、上記した実施形態や変形例を適宜組み合わせてもよい。 In addition, it is possible to appropriately replace the components in the above-described embodiment with known components without departing from the scope of the present invention, and the above-described embodiments and modifications may be combined as appropriate.
