Description

[Detailed explanation of the invention] <Industrial application field> This invention relates to containers for storing ice cream, etc., and more specifically, to containers with lids made of synthetic resin sheets that prevent the lids from accidentally coming off. The present invention relates to a container having a structure.

<Prior art and problems> Conventionally, containers for storing ice cream, etc. have been used not only for containers that directly store ice cream, etc., but also for containers containing ice cream in Watsuful cone containers that can be eaten as is. In some cases, the container body is covered with a lid made of a different material as appropriate.

However, as a container for ice cream, etc.
While it is required that the lid can be opened easily, it is also required that the lid not be accidentally opened during transportation and storage. Therefore, it is necessary to maintain the adhesion stability of the lid through appropriate engagement between the container body and the lid, but conventional containers have not been sufficiently improved in this respect.

That is, in a conventional container such as that disclosed in Utility Model Publication No. 17729/1983, a periphery having a hanging edge is provided at the mouth of the container body, and the protrusion of the lid body is engaged with this periphery. Therefore, in such a structure, if the engagement force between the protrusion and the hanging edge is weakened so that the lid can be opened easily, the lid can be easily opened even by vibrations during transportation. There was a problem where the

On the other hand, increasing the engagement force between the protrusion and the hanging edge increases resistance to vibrations, etc., but the force required to open the lid increases accordingly, resulting in the problem that the lid becomes difficult to open. .

<Purpose> Therefore, in this invention, the container main body and the lid are connected at the hinge part, and the lid has an engagement structure that can be easily opened, and also prevents the lid from being opened accidentally. We are trying to provide a container that has an engagement structure that does not exist.

<Means for Solving the Problems> Regarding the structure of the container in the invention to achieve the above-mentioned object, the container is made entirely of a synthetic resin sheet, and the lid is connected via a hinge part. The container body is connected to the container main body, and the mouth of the container main body has a hanging edge around the periphery along the approximate outline, and the lid has a first protrusion that can engage with the lower part of the hanging edge. The container body has an upwardly protruding periphery along the mouth near the hinge, and an undercut-like portion is formed on at least the outer periphery of the protruding periphery. A recess is formed in the body at a position corresponding to the protruding peripheral edge of the container body, and a second protrusion is formed at a position corresponding to the outer peripheral undercut-shaped portion of the protruding peripheral edge, and the first and second protrusions are formed in the body. It is characterized in that the lid body can be fitted and engaged with the container body at a portion of the container body.

<Function> According to the container for ice cream or the like having the above structure, since the engagement of the lid with the container body is strengthened near the hinge, the engagement force near the hinge becomes relatively high, and the hinge The engagement force of the first protrusion at a portion remote from the first protrusion becomes relatively weak. As a result, when force is applied in the direction of opening the lid around the hinge, the highest torque is applied to the part with the weakest engagement force, making it easy to open the lid with relatively little force. I can do it.

On the other hand, when vibrations, etc. act on the lid, these vibrations propagate and are dispersed throughout the mouth of the container body, so even if a considerable force is applied to the lid due to the vibrations, The engagement force of the first protrusion that can engage with the lower part of the hanging edge of the periphery and the engagement force of the second protrusion that corresponds to the undercut-shaped portion of the protruding periphery combine to prevent the lid from being opened. can be prevented.

<Example> Next, an example of this invention will be described below with reference to the drawings.

Reference numeral 10 denotes a long, approximately conical container body, and 20 an inverted bowl-shaped lid, both of which are integrally connected at a hinge portion 30.Although opaque materials can be formed and used, transparent or translucent materials are made of synthetic resin. It is preferably formed from a sheet by molding, and has flexibility as a whole. Reference numeral 11 denotes a peripheral edge along a substantially circular outline serving as the opening of the container body 10, and a hanging edge 12 is formed on this peripheral edge 11. Reference numeral 21 denotes the inner peripheral edge of the lid 20, and the inner peripheral edge 21 has a first protrusion 22 (hereinafter simply referred to as "protrusion 22") that can engage with the lower part of the hanging edge 12 of the container body 10. A plurality of them are formed at appropriate intervals.

Next, 13 is a protruding peripheral portion, and the container body 10
It is formed along the mouth near the hinge part 30 and protrudes upward, and has a length substantially close to the width of the hinge part 30 . The outer periphery 14 of the protruding peripheral edge portion 13 is formed into an undercut shape. Reference numeral 23 denotes a recessed portion formed at the inner peripheral edge position of the lid body 20 corresponding to the protruding peripheral edge portion 13, and 24 represents a recessed portion formed in the lid body 20 so as to be able to engage with the undercut-shaped portion of the outer periphery 14 of the protruding peripheral edge portion 13. This is a second protrusion (hereinafter simply referred to as "protrusion 24") formed to protrude from the inner peripheral edge of.

The shapes and lengths of the above-mentioned protrusion 22, protruding peripheral portion 13, and protrusion 24 can be variously implemented depending on the shape, length, etc. of the portions with which they engage. Furthermore, the synthetic resin sheet forming the container of this invention can be formed using only various non-foamed sheets or foamed sheets.

<How to use and function> To use this invented container described above, cover the container body 10 with the lid 20 centered around the hinge part 30, and insert the protrusion 22 on the inner peripheral edge 21 of the lid 20 into the container body 10. engages below the hanging edge 12;
A recessed portion 23 formed in the inner peripheral edge 21 of the lid body 20
is fitted into the protruding peripheral edge 13 of the container body 10, and the protrusion 24 provided on the inner peripheral edge 21 of the lid body 20 engages with the undercut-shaped portion of the outer circumference 14 of the protruding peripheral edge 13.

Therefore, not only the engagement of the protrusion 22 with the lower part of the depending edge 12 but also the engagement of the protruding peripheral edge 1 near the hinge portion 30
3 and the recessed part 23, and the undercut-shaped part of the outer periphery 14 of the peripheral protrusion 14 and the protrusion 24 engage with each other, so that the lid body 20 attempts to return to its original state around the hinge part 30.
The state of engagement is such that it can sufficiently overcome the repulsion of the lid body 20, and the attached state of the lid body 20 can be stably maintained without causing the lid body 20 to be opened inadvertently. Also, the container body 10
By grasping the cover body 20 and lightly pushing up the cover body 20 with the fingertips of the thumb or the like, the cover body 20 can be opened smoothly by disengaging each part even with the action of one hand.

<Effects of the Invention> With the container of this invention, the engagement force near the hinge is relatively strong, and the engagement force of the protrusions away from the hinge is relatively weak, so that when force is applied in the direction of opening the lid from the hinge, a relatively small force is required to open the lid. Therefore, even small children or elderly people can easily open the container with one hand by gently pushing it up with the fingertip of their thumb or other finger.

On the other hand, when vibrations etc. act on the lid, it is possible to prevent the lid from opening even if a considerable force is applied, resulting in a stable closed state of the lid.
Ice cream and other contents can be protected.

As described above, the container of the present invention is convenient and can satisfy the mutually contradictory requirements of being easy to open and keeping the lid in a stable closed state.
