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. In particular, it relates to 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 with your hands 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 state, 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 provided on the inner surface of the body, and a lid fixed by fitting the outer periphery into the recess, the lid comprising: Consisting of a laminate having a resin layer on at least the upper surface, a knob is formed on a part of the outer periphery, the knob is bent and adhered to the upper surface of the lid, and the knob can be easily peeled off by tearing off the resin layer. The gist is a tamper-proof container that is characterized by the ability to

[Effect]

In the tamper-proof container configured as described above, the lid can be opened by manually pinching the tip of the knob that is glued to the top of the lid and pulling it upward. The layers will be torn off. Therefore, traces of the opening remain, and even if the lid is opened and then closed again, it is easy to detect that the lid has been opened.

〔Example〕

Hereinafter, preferred embodiments of the present invention shown in the drawings will be described in detail. In FIGS. 1 and 2, 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. A knob 4 is formed, and as shown in an enlarged view in FIG. 3, the knob 4 is bent over the top surface of the lid and is adhered except for at least the tip 4A. This lid 3 is composed of a laminate consisting of a paper base 6 and a resin layer 7 provided on both sides of the base material.
A weak sealing portion 8 having a weak adhesive force between the resin layer 7 and the resin layer 7 is formed. Therefore, it is possible to easily peel off the knob 4 from the top surface of the lid 3 using the weak seal portion 8, and when it is peeled off, the resin layer 7 is torn off, leaving a trace. Here, the ease with which the knob 4 is peeled off from the top surface of the lid 3 is determined by the ease with which the tip of the knob 4 is peeled off when the lid 3 is fitted and fixed in the annular recess of the container body 2 as shown in FIG.
The knob 4 is designed to be peeled off from the upper surface of the lid before the lid 3 is removed from the annular recess 2A when the lid A is pinched with fingers and pulled up. The knob 4 and the top surface of the lid may be bonded by any method such as heat sealing or using an adhesive. The weak seal portion 8 can be formed by applying an adhesion inhibitor such as silicone or wax to the paper surface before laminating the resin layer 7 on the paper 6. Note that it is desirable that the weak seal portion 8 is formed not only at the portion where the knob 4 is folded over, but also continuously in the vicinity thereof.

The knob 4 is usually formed as a part of the lid 3 with the same thickness as the lid 3, but if the knob is too thick and it is difficult to bend it and glue it to the top of the lid,
Knob 4 may be made thinner. However, after the knob 4 is peeled off from the top surface of the lid, it is preferable to have a thickness that allows the knob 4 to stand on its own due to its own elasticity and not easily fall onto the top surface of the lid. Materials constituting the lid 3 include paper, plastic, etc., which have resin layers on both sides, similar to conventional lids.

In the tamper-proof container 1 having the above structure, when opening the lid 3, first grasp the tip of the knob 4 glued to the lid 3 with your hand and pull it upward. Then, first, the knob 4 is peeled off from the lid as shown by the two-dot chain line in FIGS. 1 and 3, and then the lid 3 is removed from the annular recess in the body and opened. Therefore, once the lid is opened, the knob 4 stands up from the lid 3, leaving traces of the opening. At this time, if the knob 4 is made of a material with appropriate elasticity and thickness, it will be difficult to fold and adhere the knob 4 once removed to the top surface of the lid 3.
It is difficult to hide evidence of tampering. Furthermore, when the knob 4 is peeled off, the resin layer 7A of the weak seal part 8 is peeled off along the weak seal part 8 and is torn off from the resin layer 7 that is firmly fixed to the paper 6, leaving a very clear trace. From this point of view, it is not possible to conceal the opening of the package. In particular, when a weak seal portion 8 is provided that extends beyond the folded portion of the knob 4,
Since the resin layer 7A in that part is torn, even if the knob 4 is folded over and bonded again, the resin layer in the part without the knob 4 is torn and it is impossible to hide the traces of opening.

[Effect of idea]

As described above, the tamper-proof container of the present invention has a structure in which the knob used to pull up the lid is removably glued to the top surface of the lid, and the resin layer is torn off when the knob is peeled off. Once the package is opened, the tab peels off from the lid, leaving a clear trace, making it easy to determine whether or not tampering has occurred, thereby making it possible to prevent tampering.
