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. It is connected to the container body, and the mouth of the container body has a peripheral edge along a substantially circular line and a corner peripheral edge along a substantially hook-shaped line protruding outward near the hinge part. Each of the peripheral edges has a hanging edge, and the lid body has a protrusion formed on the inner peripheral edge that can engage with the lower part of the hanging edge on the peripheral edge side along the above-mentioned substantially circular line, and the above-mentioned substantially hook. A corner protrusion that can be engaged with the lower part of the hanging edge on the peripheral side of the corner along the shape line is formed on the inner peripheral edge near the hinge part, and the hanging edge on the peripheral side along the substantially circular line and this A combination with a protrusion that can engage with the lower part of the hanging edge, and a corner protrusion that can engage with the hanging edge on the corner peripheral edge side along the substantially hook-shaped line and the lower part of this hanging edge. It is characterized in that the lid body can be engaged and attached to the container body in combination.

<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 protrusion at a portion away from the surface 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 engaging force of the corner protrusion that can engage with the lower part of the hanging edge on the peripheral side of the corner along the substantially hook-shaped line, and the engaging force of the protrusion that can engage with the hanging edge on the peripheral side along the approximately circular line. Together with the engagement force, it is possible to prevent the lid from being opened.

<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, and can be formed and used even if they are opaque.
It is preferably formed by molding from a transparent or translucent synthetic resin sheet, and has flexibility as a whole. 11 is a periphery of the mouth of the container body 10 along a substantially circular line; 12 is a periphery of the mouth near the hinge part along a substantially hook-shaped line; each has a hanging edge 13 or 14; are doing.

Reference numerals 21 and 22 denote an inner peripheral edge of the lid body 20, 23 a protrusion that can be engaged with the lower part of the hanging edge 13 on the side along the above-mentioned substantially circular line, and 24 a hanging edge on the side along the above-mentioned substantially hook-shaped line. These are corner protrusions that can be engaged with the lower part of the lid 20, and both of them are formed protrudingly on the inner peripheral edge of the lid 20, and when these protrusions 23 and 24 engage with the hanging edges 13 and 14, the container is closed. Lid body 20 with respect to main body 10
will be engaged and applied.

In the case of the figure, the corner protrusion 24 among the protrusions is a protrusion 23 that engages with the hanging edge 13 on the side along the substantially circular line.
Although the example shows a case in which the program is continuous with a part of the program, there is no problem even if the program is implemented separately.

Further, the length and shape of each of the above-mentioned protrusions can be variously implemented depending on the locations where these protrusions are to be engaged.

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 the above-mentioned container of this invention, cover the container body 10 with the lid 20 centered around the hinge part 30, and press one of the protrusions 23 on the inner peripheral edge of the lid 20.
is engaged with the lower part of the hanging edge 13 on the side of the container body 10 along the substantially circular line, and the other corner protrusion 24 is engaged with the lower part of the hanging edge 13 on the side of the container body 10 along the substantially hook-shaped line near the hinge part. will engage the lower part of the depending edge 14 of.

Therefore, not only the lower part of the hanging edge 13 on the side along the substantially circular line and the protrusion 23 but also the hanging edge on the side along the substantially hooked line near the hinge part 30 The lid body 20 tries to return to its original state around the hinge part 30 due to the engagement between the lower part of the lid body 14 and the corner protrusion part 24.
The state of engagement is such that it can sufficiently overcome the repulsion of If the lid body 20 is pushed up lightly, the lid body 20 can be opened smoothly even with the action of one hand by disengaging each part of the lid body 20.

<Effects of the invention> According to the container of this invention, the engagement force near the hinge portion is relatively high, and the engagement force of the protrusion at a portion away from the hinge portion is relatively weak. If you apply force in the direction you want to open the lid, you can easily open it with a relatively small force. Therefore, even a small child or an elderly person can easily open a container with one hand by pushing the container lightly with the tip of a finger such as a thumb.

On the other hand, when vibrations or the like act on the lid, it is possible to prevent the lid from opening even if a considerable force is applied, thereby stabilizing the 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.
