Description

【０００１】
【発明の属する技術分野】
本発明は廃棄時の体積を狭少化してゴミの減量化が可能に設けた、合成樹脂製の包装用容器に関する。
【０００２】
【従来の技術】
この種の容器として、例えば特開平8‐268435号の容器が知られている。
該容器は、容器体胴部上端に周設した外向きフランジ一半部のフランジ巾中間部に、フランジ外縁に沿って破断線を穿設しておき、容器廃棄時にはその破断線切断により、フランジに両端を接続する、Ｕ字状ないしＣ字状の紐を形成し、押し潰した容器体外面へ容器体胴部が弾性復元しないよう、上記紐を掛け渡して廃棄するよう設けたものである。
【０００３】
【発明が解決しようとする課題】
上記従来方法は、容器体が胴部上端に外向きフランジを有し、かつ胴部が大外径である場合に行えるものであり、例えば壜状の容器で胴部上端から口頸部を起立し、該口頸部にキャップを嵌合させた容器には応用することが出来なかった。
本発明はそのような口頸部を有し、該口頸部にキャップを嵌合させている容器を処理できるよう設けたものである。
【０００４】
【課題を解決するための手段】
底壁の左右方向両端と中央部とを脚部２，３として残して、残余底壁部分下面に下方および前後両方向開放の凹部を形成すると共に、
底壁周縁から起立する胴部５上端から直接ないし肩部を介してキャップ嵌合用の口頸部７を起立する、弾性変形可能な容器本体１と、
上記口頸部外面へ嵌合させた周壁12を有するキャップ11とからなり、
該キャップは、周壁上部を小外径部13として、該小外径部外面へリング11b を着脱自在に嵌合すると共に、該リングを小外径部下方周壁部分の上端一部とヒンジ14で揺動自在に連結して、キャップ全体を一体成形し、
又リング11b は、上記中央脚部３外面へかた嵌め可能な大きさに形成した。
【０００５】
【発明の実施の形態】
以下図面について説明すると、１は合成樹脂製の弾性変形可能な容器本体である。該容器本体は底壁の左右方向両端と中央部とを脚部２，３として残して、残りの底壁部分下面に下方および前後両方向開放の凹部を形成し、又その中央脚部３の下端外周に係合突条４を周設している。上記左右両脚部の各下端面は、容器正立時においてそれぞれ接地面となるよう同一水平面上に位置するよう設ける。左右両脚部２，２を正立可能な大きさとすれば、中央脚部３下面はそれ等脚部より短かくても差支えない。
又底壁周縁から起立する胴部５上端から肩部６を介してキャップ嵌合用の口頸部７を起立する。胴部５は弾性変形可能であり、肩部６は必しも必要としない。
【０００６】
上記口頸部７へはキャップ11を嵌合させる。該キャップは口頸部外面へ嵌合させる周壁12を有し、該周壁上部を小外径部13とするキャップ本体11a と、上記小外径部外面へ着脱自在に嵌合させたリング11b とからなり、これ等キャップ本体とリング11b とは、小外径部13を除く周壁部分の上端外縁の一部とヒンジ14で揺動自在に連結する。小外径部13は上部大外径のテーパとしてリングの抜出しを防止している。リング11b の大きさは、既述中央脚部３外面へかた嵌め可能な大きさとし、小外径部13からリング11b を外した状態で合成樹脂材により一体成形している。尚図示例のように小外径部13からのリング取外しの便宜のため、指掛け突部15をヒンジと対向する側に付設してもよい。
以上構成とした容器を廃棄する際は、図３が示すように容器本体１を圧搾した状態で胴部５を折曲げ、リング11b を小外径部13から外して該リング内へ中央脚部３をかた嵌めすればよい。
【０００７】
【発明の効果】
本発明は既述構成とするものであり、キャップ11に付設したリング11b を容器本体の底壁に設けた中央脚部３外面へかた嵌めするよう設けたから、容器本体脚部は圧搾され、かつ折曲げられることととなってその体積を減少できることとなり、上記中央脚部３下面は底壁に比して小面積となって容器の正立が困難となる筈であるが、底壁両端に左右脚部２を形成しているからその容器の正立が困難となることはなく、リング11b は、キャップ周壁の上部を小外径部13として、該小外径部へヒンジ14によりキャップと連結状態で嵌合させるから、容器廃棄前にそのリングが容器使用の邪魔となることもない。

BACKGROUND OF THE INVENTION
The present invention relates to a synthetic resin packaging container provided with a reduced volume at the time of disposal so as to reduce waste.
[0002]
[Prior art]
As this type of container, for example, a container disclosed in JP-A-8-268435 is known.
The container has a rupture line drilled along the flange outer edge in the flange width middle part of the outward flange half that is provided around the upper end of the container body. A U-shaped or C-shaped string connecting both ends is formed, and the string is hung and discarded so that the container body does not elastically recover from the crushed container body outer surface.
[0003]
[Problems to be solved by the invention]
The conventional method described above can be performed when the container body has an outward flange at the upper end of the trunk and the trunk has a large outer diameter. For example, the mouth and neck are raised from the upper end of the trunk in a bowl-shaped container. However, it could not be applied to a container having a cap fitted to the mouth and neck.
The present invention is provided so that a container having such a mouth-and-neck portion and having a cap fitted to the mouth-and-neck portion can be processed.
[0004]
[Means for Solving the Problems]
The left and right ends and the center of the bottom wall are left as the leg portions 2 and 3, and the bottom portion of the remaining bottom wall portion is formed with recesses that are open downward and front and rear in both directions,
An elastically deformable container main body 1 that erects the neck 5 for cap fitting directly from the upper end of the body 5 standing from the periphery of the bottom wall or through the shoulder;
A cap 11 having a peripheral wall 12 fitted to the outer surface of the mouth and neck,
The cap has a small outer diameter portion 13 at the top of the peripheral wall, and a ring 11b is detachably fitted to the outer surface of the small outer diameter portion. It is connected so that it can swing freely, and the entire cap is integrally molded.
The ring 11b is formed in a size that can be fitted to the outer surface of the central leg 3.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawings, reference numeral 1 denotes an elastically deformable container body made of synthetic resin. The container main body has left and right ends and a center portion of the bottom wall as legs 2 and 3, and the bottom surface of the remaining bottom wall portion is formed with a recess that is open downward and in both the front and rear directions. Engaging protrusions 4 are provided around the outer periphery. The lower end surfaces of the left and right leg portions are provided so as to be positioned on the same horizontal plane so as to be grounded surfaces when the container is upright. If the left and right legs 2 and 2 are sized so that they can stand upright, the lower surface of the center leg 3 may be shorter than the legs.
Further, the cap neck part 7 is erected from the upper end of the body part 5 standing from the peripheral edge of the bottom wall through the shoulder part 6. The body 5 is elastically deformable, and the shoulder 6 is not always necessary.
[0006]
A cap 11 is fitted to the mouth neck portion 7. The cap has a peripheral wall 12 to be fitted to the outer surface of the mouth neck portion, a cap body 11a having the upper portion of the peripheral wall as a small outer diameter portion 13, and a ring 11b detachably fitted to the outer surface of the small outer diameter portion. The cap body and the ring 11b are connected to a part of the upper edge of the peripheral wall portion excluding the small outer diameter portion 13 by a hinge 14 so as to be swingable. The small outer diameter portion 13 is an upper large outer diameter taper that prevents the ring from being pulled out. The size of the ring 11b is such that the ring 11b can be fitted to the outer surface of the central leg 3 described above, and is integrally formed of a synthetic resin material with the ring 11b removed from the small outer diameter portion 13. As shown in the figure, for the convenience of removing the ring from the small outer diameter portion 13, the finger hooking protrusion 15 may be provided on the side facing the hinge.
When discarding the container configured as described above, as shown in FIG. 3, the trunk 5 is bent in a state where the container body 1 is squeezed, the ring 11b is removed from the small outer diameter part 13, and the central leg is inserted into the ring. 3 may be fitted.
[0007]
【The invention's effect】
The present invention is configured as described above, and since the ring 11b attached to the cap 11 is provided so as to be fitted to the outer surface of the central leg 3 provided on the bottom wall of the container main body, the container main body leg is compressed, In addition, the volume of the container can be reduced, and the lower surface of the central leg 3 is smaller than the bottom wall, making it difficult for the container to stand upright. Since the right and left leg portions 2 are formed on the left and right sides, the container does not become difficult to stand upright. So that the ring does not interfere with the use of the container before the container is discarded.
