DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a food filled product,
The present invention relates to a container having a function of preventing unauthorized opening in a distribution process.

[0002]

2. Description of the Related Art Conventionally, when a food or the like is distributed in a distribution process, particularly at a store, the food is illegally opened and foreign substances are mixed therein.
In addition, containers for preventing quality deterioration and the like have been developed. For example, illegitimate opening prevention means such as attaching a label to the opening portion of the container body, wrapping a tape with an adhesive, or covering with a shrink film is adopted. Containers with this kind of tamper-evident function are generally molded from thin synthetic resin or paper-based packaging material and filled with contents such as individual food containers filled with food such as ice cream. Is often used for foods that can be used all at once.

In addition, as described in Japanese Patent Application Laid-Open No. 52-11017, an upper step is provided on the outer surface on the mouth side, and a lower flange is provided below the upper step to form a container body. The lid fitted to the mouth of the main body is provided with a lid step that engages with the upper step of the container main body inside the skirt that hangs down from the top plate. Positioned inside, tamper-evident prevention container that is opened by separating the lower skirt portion along the cut line provided in the skirt portion, or, as described in JP-A-8-244812, the container body A notch is provided in the opening of the flange and the locking portion between the lid and the flange, and a notch is provided on the lid fitted to the container main body, with a side wall having a height reaching the container main body flange and a notch in the flange. Provide an opening tab to be mounted, and A tamper-evident container or the like that is engaged with the locking portion of the main body has also been developed. This kind of container is used for filling food to be used in several to several tens of times, and it is necessary to store the food for a certain period of time even after it has been opened, so it has a high reseal function. .

[0004]

As described above, containers having various functions for preventing unauthorized opening have been developed. However, a label is attached to an opening of the container body, or a tape with an adhesive is wound around. The method of doing is that if there is a change in temperature or humidity during storage, the adhesive strength will fall and it will peel off and fall off,
In addition, there are many problems in use, such as breakage due to friction during transportation. In addition, the method of covering with a shrink film has a problem that a predetermined fitting portion between the lid and the container body cannot be accurately covered with a high-speed packaging machine. When the shrink film for opening prevention is stuck and filled from the bottom side, the containers come into contact with each other in the process of container supply, filling, sealing, cardboard packaging, etc. There is a problem such as lowering. In addition, when opening the package, it takes time and effort to remove the shrink film, and there is a problem that the removed shrink film generates extra dust.

On the other hand, JP-A-52-11017 and JP-A-8-24
The tamper-evident container described in Japanese Patent No. 4812 has a problem that the structure of the container body and the lid becomes complicated because of the reseal function, and the cost of the container inevitably increases. It takes time and effort to cut from the cutting line provided in the above, and there is also a problem of generation of dust. Therefore, there is a problem that this kind of container cannot be used as a disposable individual food container. Thus, the tamper-evident container has different functions depending on the type and use of the contents to be filled, but the present invention provides a low-cost, individually tamper-resistant food container. It is intended to provide. That is, at a lower cost, containers provided with a tamper-proof function that are molded with a packaging material mainly composed of synthetic resin, paper, or the like, filled with individual foods, and discarded after the foods are ingested are discarded. The task is to do so.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a container having the following function for preventing unauthorized opening. That is, the container of the present invention
It is molded with a packaging material in which synthetic resin is laminated on a synthetic resin sheet or paper, and the structure is composed of a container body having an outward flange at the opening and an outer periphery of a top plate covering the opening of the container body. In a container consisting of a lid body having a hanging skirt portion, at two or more separated portions of the edge of the lid body,
An upwardly-facing claw portion is formed on the inside, and the claw portion is engaged with a flange portion of the container body to prevent opening. It is a configuration provided. Further, the two or more opening prevention portions formed on the edge of the skirt portion of the lid main body are configured to have symmetrical positions or positions close thereto.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.
The present invention relates to a food filling container having a tamper-proof function.The container of the present invention is filled with food such as ice cream, and the filling amount is the amount taken at one time, for example, 50 to 200 ml. To the extent, they are particularly suitable for those used for individual consumption. The packaging material used in the container of the present invention is a material obtained by laminating a synthetic resin film such as polyethylene or polyester on the surface layer mainly of paper, or polyethylene, polystyrene, polyethylene terephthalate, polyvinyl chloride, polyacrylonitrile. -A thin and flexible packaging material is preferably used in which a thermoplastic synthetic resin such as butadiene / styrene is used. This is, as is clear from the examples described later, when filling the container body with the contents and covering the lid, the edge of the lid,
Since the upward claw portion is formed inside, the claw portion is not locked unless it gets over the flange portion of the container body, and the skirt portion on both sides of the claw portion has a break for opening. Since the line is provided, in the case of a packaging material having high rigidity at the time of covering, the cut line is cut, so that flexibility is required.

[0008] The container of the present invention is formed by using the above-mentioned flexible packaging material, using a molding means suitable for the packaging material such as vacuum molding, air pressure molding, compression molding, injection molding, or punching with a mold. Formed by Applicable foods are solid or powdered foods, such as granular chocolate, ice cream, caramel, gum and other confections and frozen desserts, or natto, jam and butter. However, once opened, the resealing function is deteriorated, so it is preferable to use up at once or fill up the amount to be taken.

The opening prevention portion (c) is provided at two symmetrical positions of the skirt portion (5) of the lid body (b).
Claw (7) upward from the lower edge (6) of the
(7) is formed to protrude. Cut lines (8) and (8) for cutting at the time of opening are formed in the skirt portion (5) at positions on both sides in the width direction of the claw portion (7).

When the container body (a) is filled with contents, for example, food (d), and the lid body (b) is covered with the claws (7), the tip of the claws (7) has elasticity. In order to prevent the break lines (8) and (8) from being cut even if it exceeds the leading edge of the collar (3) or (3 ′), 7) and collar (3) or (3 ')
It is necessary to properly design the length and width in consideration of the wrapping material so that the break lines (8) and (8) are broken if the force is applied due to the locking.

The container body (a) having the above structure is filled with the food (d) as the content, and the lid body (b) is covered with the food (d). In the lid body (b), claw portions (7) and (7), which are formed inward at two symmetrical portions of the skirt portion (5) and project upward, are curved with the flexibility of the material. Opening prevention portions (c) and (c) that lock over the leading edge of the flange portion (3) or (3 ′) of the container body (a) are configured. At this time, if the length and width of the claw portion are properly designed in consideration of the packaging material as described above, the cut lines (8) and (8) formed on the skirt portion (5) will not be cut off.

The container body (a) is filled with the food (d) as a content, and the lid body (b) is covered with the food (d). The claws (7) and (7) of the lid body (b) are covered. Even if the lid body (b) is simply lifted upward to open the lid of the product locked in the flange portion (3) or (3 ') of the container body (a), the claw portion (7) is opened. The lid body (b) cannot be more easily opened than the container body (a) due to the locking of the flange part (3) or (3 ') with (7).

However, the lid body (b) is forcibly opened.
Is pulled upward, the claw (7) at the symmetrical position,
In any of (7), the cut lines (8) and (8) provided in the skirt portion (5) are cut off. From the above, the break line (8) provided on the skirt portion (5) during storage, transfer, or display at the store, of the product,
If (8) is cut off, it means that the opening prevention section (c) has been destroyed, so that unauthorized opening has been performed.

Normally, when used by a customer, one of the opening prevention portions (c) and (c) is pinched between the cut lines (8) and (8) of the skirt portion (5). Cut the break lines (8) and (8) to release the engagement between the claw portion (7) and the flange portion (3) or (3 '), and open the lid body (b) from the container body (a). To show off. Such an unsealing prevention part (c) has no effect at one place, and it is necessary that there are two or more places, and the position must be a symmetrical position or a position close thereto.

[0017]

According to the present invention, there is provided a container body having an outward flange at an opening according to the first aspect of the present invention. Because the lid body with the cover is covered and the claws are locked to the flange of the container body, it is not easily opened even if the lid body is simply pulled up. Since the cut lines provided at both ends of the width of the portion are cut, it can be easily determined that the package has been illegally opened. However, in the case of normal opening, it is easy to remove the lid by first pulling outward the part where the score line is cut and pulling the claw part away from the collar part of the container body while cutting the score line. it can. According to the second aspect of the present invention, two or more opening preventing portions are formed on the edge of the lid main body, and a simple structure provided at a symmetrical position or a position close thereto is more powerful. Unless the lid body is lifted by force, the lid is not opened, and unauthorized opening can be prevented. Furthermore, although the tamper-evident container of the present invention has a simple structure and can be provided at low cost, its function is reliable and disposal after use is easy.
