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 attempts 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 gist of the present invention is a tamper-proof container characterized by having a knob provided on the container body adhered to the container body by heat sealing.

[Effect]

In the tamper-proof container configured as described above, when opening the container, the tab is peeled off from the container body and the lid is opened using the tab. For this reason, once the lid is opened, traces of peeling will always remain on the container body or the knob, and even if the lid is re-closed after opening, traces of tearing will remain.
It can be easily detected that it has been opened.
Furthermore, by using heat sealing to adhere the tab to the container body, the adhesive does not enter the container body, making it extremely hygienic.

〔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. At least a portion 5 of 4 is adhered to the container body 2. The knob 4 used here is not limited to a linear knob that contacts the inner surface of the body of the container body 2 and extends upward, as shown in FIG. , bent so as to contact the inner surface of the body of the container body 2 and the upper end of the curled portion 2B of the upper edge,
The upper surface portion 5 may be adhered to the curled portion 2B at the upper end of the container body 2. The tip of the knob 4 may extend above the upper end of the container body 2 as shown in FIG. 1, or extend beyond the curled portion 2B as shown in FIG.
It is preferable to make it easy to pick up with fingers. The knob 4 and the container body 2 are bonded together by heat sealing. If an adhesive such as hot melt is used for this bonding, the adhesive may
However, with heat sealing, there is no such fear and it is extremely hygienic.

The knob 4 provided on the lid 3 may be formed integrally with the lid 3, or may be made separately and then attached by adhesive. As the container body 2 and the lid 3, those conventionally used, such as those made of paper with a resin layer laminated on the surface, or those made of plastic, can be used as they are. but,
When the container body 2 is made of paper and has a resin layer on its surface, it is preferable to form a weak seal portion in the portion of the container body 2 that comes into contact with the knob 4. That is, as shown in FIG. 5, when the container body 2 has a resin layer (for example, a polyethylene layer) 7 on the surface of the paper 6, the bonding strength between the paper 6 and the resin layer 7 is It is preferable to form a weak seal portion 8 and to adhere the knob 4 thereon. Such a weak seal portion 8 is created by applying silicone or silicone to the surface of the paper before laminating the resin layer 7 on the paper 6.
By applying an adhesion inhibitor such as wax,
can be formed. Note that the weak seal portion 8 may be formed only in the portion where the knob 4 contacts, but if it is formed in an annular shape around the entire circumference of the container body 2, as shown by the broken line in FIG. When fitting the lid 3 into the container body, the knob 4 is always located above the weak seal portion 8 no matter what position the lid 3 is in, and therefore there is no need to adjust the attachment angle between the container body 2 and the lid 3, which is preferable. .

In the tamper-proof container 1 having the above structure, when opening the lid 3, be sure to insert the knob 4 from the inner surface of the body of the container body 2 (Fig. 1) or from the curled portion 2B.
It has to be peeled off from the top (Figure 3), which leaves traces of peeling on the container body or the handle, leaving evidence of the opening. Therefore, even if the lid is re-closed after opening, traces of opening remain, making it easy to determine whether or not tampering has occurred. In particular, the weak seal portion 8 shown in FIG.
In the case of a container having a resin layer 7A of the weak seal part 8, the resin layer 7A of the weak seal part 8 is easily peeled off from the paper 6 while remaining attached to the knob 4, so it is easy to peel the knob 4 from the container body, and when opening the seal, this resin layer 7A is easily peeled off from the paper 6 while remaining attached to the knob 4. Since the layer 7A is torn off from the other resin layer 7 firmly adhered to the paper 6, its traces remain very clearly. Furthermore, in the case where the weak seal part 8 is formed in an annular shape as shown in FIG. The traces of the lid being peeled off become even clearer, and even if the knob 4 is glued on again, it is impossible to hide the fact that the lid has been opened.

[Effect of idea]

As mentioned above, since the tamper-proof container of the present invention has the lid tab glued to the container body by heat sealing, once it is opened, traces of the tamper-proof container remain.
The presence or absence of tampering can be easily determined, tampering can be prevented, and it is extremely hygienic.
