Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a container, such as an ice cream container, which is closed by providing an annular recess on the inner surface of the body and fitting the outer periphery of the lid into the recess. Concerning containers designed to prevent tampering.

[Conventional technology]

Ice cream containers generally have a structure in which an annular recess is provided on the inner surface of the body of the cup-shaped container, and the outer periphery of the lid is fitted into the recess to close the container.To open the lid, simply pull the lid's knob. All you have to do is pick it up and pull it up.

[The problem that the idea aims to solve]

Recently, a vicious crime of mixing poisonous drugs into foods, medicines, etc. has occurred, and this has become a serious social problem. However, with conventional ice cream containers, in order to open the lid as described above, all you have to do is pull the lid up and remove the outer periphery of the lid from the annular recess in the body. The problem is that if a criminal opens the lid, mixes a poison into the ice cream, and then puts the lid back in its original state, it will be completely unchanged from the original condition, making it impossible to tell whether or not it has been tampered with. has arisen. This has caused a great deal of anxiety among consumers, and there has been a desire for a tamper-proof container that allows the user to see at a glance whether or not the product has been tampered with.

The present invention was developed based on such a request, and the purpose of the present invention is to provide a tamper-proof container that leaves traces once the lid is opened, so that even if the lid is closed again, it can be easily determined whether the lid has been opened or not. do.

[Means to solve the problem]

The present invention, which has been made to achieve the above object, provides a container consisting of a container body having an annular recess on the inner surface of the body, and a lid fixed by fitting the outer periphery into the recess. The object of the present invention is to provide a tamper-proof container characterized in that a knob is provided at the top of the container, and a linear weakened portion extending from the outer periphery of the lid toward the inside is provided near the knob.

[Effect]

The tamper-proof container configured as described above can be opened by grasping the knob formed on the lid and pulling it up, but at this time, the linear weak part formed near the knob is torn, leaving traces of the opening. Therefore, even if an attempt is made to close the lid once it has been opened to return it to the state before opening, it will be easy to detect that the lid has been opened because the linear weakened portion is torn.

〔Example〕

Hereinafter, preferred embodiments of the present invention shown in the drawings will be described in detail. In FIGS. 1 to 3, a tamper-proof container 1 consists of a container body 2 having an annular recess 2A in the body and a lid 3 that fits into the annular recess 2A. 4 is provided, and a linear weak portion 5 is formed in the vicinity of the knob 4 from the outer periphery of the lid toward the inside. This linear weak portion 5 is provided so that the lid 3 can be easily torn at this portion, and for example, as shown in FIG. A line formed by cutting to a thickness of , that is, a half-cut line 5
A material consisting of A and 5B can be used. These half-cut lines 5A and 5B may be continuous or may be interrupted at appropriate intervals to form a broken line, but the half-cut lines 5A and 5B on the upper side
It is preferable to use a broken line so that it can be clearly seen that it has been torn. The distance between the upper and lower half-cut lines 5A and 5B is determined by taking into account the ease of tearing and processing accuracy, and although they are very close in the drawing, it is difficult to process easily for lids that easily peel off from the center. You may leave an appropriate distance between them. The ease with which the linear weak portion 5 is torn is determined such that the linear weak portion 5 is torn before the lid 3 is removed when the knob 4 of the lid 3 fitted in the desired annular recess 2A is pinched and pulled up. In addition, lid 3
The fit between the annular recess 2A and the annular recess 2A may be tighter and therefore more difficult to dislodge than in conventional ice cream containers.

The formation position, direction, number, etc. of the linear weak portions 5 are not limited to those shown in FIG. 2, and can be changed as appropriate.
FIG. 5 shows a modification example, in which an arcuate linear weak portion 5 is formed near the knob 4, and a fold is formed between the end of the linear weak portion 5 and the outer periphery of the lid. A line of sight 6 is formed. Moreover, FIGS. 6 and 7 show still other modified examples, and in this example,
Linear weakened portions 5 are formed on both sides of the knob 4, and a fold line 6 is formed at a position connecting the ends of the linear weakened portions 5 on both sides.

In the tamper-proof container 1 configured as described above, when the lid 3 is opened by pinching the knob 4 with fingers and pulling upward, the lid 3 is torn along the linear weak part 5, and then the outer periphery of the lid is broken into the annular shape of the body. It comes off from the recess 2A and is opened. At this time, even if the fitting between the annular recess 2A and the outer periphery of the lid 3 is tight, the lid 3 is torn at the linear weakened portion 5, allowing escape and the lid 3 to be easily removed. Furthermore, once the package is opened, the linear weakened portion 5 is torn, leaving traces of the opening, which can be easily identified even if the package is re-closed after the package has been opened. In the embodiments shown in FIGS. 5, 6, and 7, when the knob 4 is pulled up to open the package, the part continuing from the knob 4 bends from the crease line 6, as shown in FIG. 6, for example. , which has the advantage of transmitting force well to the rest of the lid and being easy to open.

[Effect of idea]

As described above, since the tamper-proof container of the present invention is provided with the linear weak portion 5 extending from the outer periphery of the lid to the inside near the knob 4 of the lid 3, once the container is opened,
The linear weakened portion 5 is torn, leaving traces of opening, making it easy to determine whether or not tampering has occurred, thereby making it possible to prevent tampering.
