DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging container comprising a container body made of a synthetic resin and a lid fitted to the container body. And a tamper-resistant packaging container.

[0002]

2. Description of the Related Art At present, a packaging container in which a lid is internally or externally fitted to an opening of a container body for storing foods such as confectionery and lunch boxes so as to be sealed is currently available. Various forms have been proposed. Among them,
In the case of the type in which the lid body is fitted to the outside or inside of the container body, the outer periphery thereof does not have to be further wrapped by a wrap or a film. It is often manufactured by means of molding or the like by integral molding using a synthetic resin as a material.

[0003] However, in the case of a packaging container in which the lid is fitted inside or outside of the container body, it is often arranged as it is at the store, and it is easy for the lid to be removed or tampered with. I have. Due to such mischief or tampering, once opened packaging containers and storage items have no value as merchandise, it is necessary to make such items easily visible. .

[0004] As a conventional method for easily detecting such tampering by visual inspection, for example, a seal that is broken when the seal is broken is attached to the boundary between the container body and the lid. There are various types such as sticking an unrepairable seal that appears easily when opened. However, preparing such a seal and affixing it to the packaging container after the contents are packed has to be provided with a large facility separately or manually.

[0005] However, it is very difficult to introduce a facility for sticking a seal with containers of this kind having various sizes and shapes of containers. This is unavoidable.

The inventor of the present invention has made various studies as to whether falsification can be easily prevented, and as a result, completed the present invention.

[0007]

SUMMARY OF THE INVENTION The present invention has been made on the basis of the above circumstances, and the problem to be solved is to prevent tampering only by fitting the lid to the container body. It is an object of the present invention to provide a packaging container which can be used.

That is, the object of the present invention according to claim 1 is that the fitting of the lid to the container body can ensure the hermeticity as it is, and even if the lid is opened due to mischief or the like. Another object of the present invention is to provide a packaging container that has been subjected to tamper-prevention, which traces can be reliably left and falsification can be easily found visually.

The object of the invention according to claim 2 is to achieve the same object as in claim 1 above.
An object of the present invention is to provide a packaging container capable of leaving traces of tampering more reliably.

[0010]

Means for Solving the Problems In order to solve the above-mentioned problems, first, means adopted by the invention according to claim 1 will be described with reference numerals used in the description of the embodiments described below. "The packaging container 100 including the container main body 10 and the lid 20 having the knob 21 which is fitted at least partially in the interior of the container main body and located in the immediate vicinity of the inner fitting portion. The lid 20 of the container body 10
A storage space 30 in which the knob 21 is stored while being surrounded by the rising wall 12 is formed at a portion where at least a part of the knob is internally fitted. When the knob 21 is stored in the storage space 30, An inward projection 14 that protrudes inward above the knob 21 is formed on the rising wall 12, and is further directed downward on the space bottom surface 11 a located between the rising walls 12. A tamper-resistant packaging container 100 "characterized by forming a fold curve 13 for facilitating bending.

That is, as shown in FIGS. 1 and 2, the packaging container 100 according to
And a lid 20 fitted to the container body 10 so as to cover the upper opening thereof.
As shown in an enlarged manner in FIG. 2, at least one corner has a storage space 30 in which the knob 21 on the lid 20 side is stored. This storage space 3
0 on the container body 10 side,
As shown in FIG.
1a and two rising walls 12 surrounding it at an angle of 90 ° are formed. As shown in FIGS. 2 and 3, an inward projection 14 is formed integrally with each of the rising walls 12.

Now, the lid 20 constructed as described above,
When the knob 21 is fitted to the container body 10 filled with stored items such as food, the knob 21 is inserted into the storage space 30 on the space bottom surface 11a where at least one corner of the flange 11 of the container body 10 is formed. Mated. At this time, since the edge of the knob 21 rides over the inward projection 14 formed on the rising wall 12 rising around the storage space 30, the knob on the lid 20 side as shown in FIG. Reference numeral 21 denotes a lower side of each inward projection 14, and comes into close contact with the space bottom surface 11a. In other words, the knob 21 on the side of the lid 20 is completely buried in the storage space 30 surrounded by the space bottom surface 11a and the two rising walls 12, and cannot be seen from the outside.

The main packaging container 100 sealed as described above.
Is to open the lid 20 from the container body 10 as follows. That is, as shown in FIG.
When the rising wall 12 surrounding the space bottom surface 11a is pressed downward with a finger, the space bottom surface 11a bends at a bent curve 13 formed on the space bottom surface 11a, and the tip of the knob 21 buried until then is exposed. You do it. Therefore, a finger is hung on the knob 21 to open the lid 20.

The above opening is mischief, and the lid 20
Is fitted to the container body 10 again.
And has not returned to the original state as shown in FIG. In addition, the inward projection 14 is formed on each rising wall 12, and this pushes up the knob 21, so that the knob 21 is not stored in the storage space 30 as shown in FIG. That is, even if the lid 20 is fitted to the container body 10, not only the deformation traces generated at the time of the previous opening remain on each rising wall 12, but also the space bottom surface 11a is deformed by the fold curve 13. Therefore, even if not as shown in FIG. 4, it is in a state of being slightly inclined downward.

Therefore, the packaging container 100 according to the first aspect of the present invention.
Is that once the lid 20 is opened,
Since it remains on the rising wall 1a and the rising wall 12, it can be easily found by visual inspection, and the function of preventing tampering can be exhibited.

In order to solve the above-mentioned problem, a means adopted by the invention according to claim 2 is that the packaging container 100 according to claim 1 is described as “in the upper part of the rising wall 12,
That is, when the bottom surface 11a of the space is bent along the folding curve 13, the marking surface 15 serving as a mark of tampering is formed by breaking or extending completely. "

That is, the packaging container 10 according to claim 2
Reference numeral 0 denotes a mark surface 15 formed on the rising wall 12 as shown in FIG. 5, and the mark surface 15 is, as shown in FIG. It extends completely beyond the elastic deformation region as shown in the figure, or completely breaks as shown in FIG. That is, in order to open the lid 20, the rising wall 12 must be pushed down as shown in FIG. 4, and once this pushing down is performed, the mark surface 15 does not return to the original state as shown in FIG. It becomes a state.

Therefore, the packaging container 1 according to claim 2 is provided.
00, once the lid 20 is opened, the space bottom 1
1a as well as the deformation of the rising wall 12
5 is also stretched or cut and deformed irreversibly, so that falsification can be reliably prevented.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a packaging container according to an embodiment of the present invention; FIG. The state in which the lid 20 is about to be fitted to the container body 10 is shown. And this packaging container 10
In the lower left part of the container body 10 constituting the container body 0 in FIG. 1, a storage space 30 in which the knob 21 on the lid 20 side is stored is formed.

The container body 10 and the lid 20 are integrally formed by injection molding using a synthetic resin or vacuum forming using a synthetic resin sheet. In the embodiment shown in FIG. It is to be “in-fitted” to the container body 10. That is, in the present embodiment, the rising wall 12 is integrally formed on the outer periphery of the flange 11 formed around the upper opening of the container body 10, and the opening edge of the lid 20 is fitted inside the rising wall 12. It was made. Thereby, in a space other than the space bottom surface 11a described later and the storage space 30 thereabove,
The lid 20 is fitted into the container body 10 without any gap, and there is no portion for opening the lid 20.
Note that the fitting of the lid 20 to the container body 10 may be a so-called “outer fitting” as long as the storage space 30 in which the knob 21 on the lid 20 side is to be stored can be formed. It goes without saying that the inner fitting portion may be provided only around the knob 21.

As shown in FIG. 1, the container body 10 has a flange 11 around an upper opening thereof.
A space bottom surface 11a for forming the storage space 30 is formed in a part of the flange 11.
1a has a substantially triangular shape as shown in FIGS. In addition, in the container main body 10 of this embodiment, except for the space bottom surface 11a, it has a rounded corner portion.

In the packaging container 100 of the present embodiment, the lid 20 is fitted inside the container main body 10, so that the rising wall 12 as shown in FIG. Is integrally molded. Therefore, in particular, the space bottom surface 11a is surrounded by two rising walls 12 orthogonal to each other as shown in FIG.
2, the storage space 30 described above is formed.

As shown in FIG. 2, a bent curve 13 is formed on the space bottom surface 11a exposed in the storage space 30. This folding curve 13 is the space bottom 1
1a and a part of the rising wall 12 integrated with the space bottom surface 11a can be pushed downward separately from the other. A small opening 13a as shown in FIG. It is formed by continuous like a so-called "perforation". Of course, each small opening 13a may be formed as a simple dent. In addition, each small opening 1
Only one of the recesses 3a and the corresponding recesses may be formed between the two rising walls 12 that cross each other.

As shown in FIGS. 2 and 3, the rising wall 12 located above the fold curve 13 has
A substantially triangular knob 2 formed at one corner
1 is formed with an inward projection 14 for locking. The height of the inward projection 14 is about 0.3 to 0.5 mm. However, when the container body 10 is modeled, it does not cause any obstacle, and the shape is changed by the modeling. It doesn't matter. On the contrary,
The crossing angle of the rising wall 12 rising on both sides of the space bottom surface 11a for forming the storage space 30 is 90 °.
On the other hand, the knob 21 on the side of the lid 20 housed between them is formed in a 90 ° triangular shape so that the knob 21 pushed into the storage space 30 is securely fixed by the two inward projections 14. It can be stopped at. The shapes of the storage space 30 and the knob 21 may be, for example, an elliptical shape in addition to those described above.

The inward projection 14 is shown by the broken curve 1 in FIG.
3 is formed above the knob 2 of the lid 20.
1 can be formed wherever it can be stopped. In particular, when a mark surface 15 as shown in FIG. 5 is formed on the upper portion of the rising wall 12, the inward protrusion 14 may be formed at a position that does not interfere with the mark surface 15.

When the both rising walls 12 enclosing the knob 21 are pushed down, the mark surface 15 is (a) in FIG.
(B), or it is cut as shown in (b) of FIG. 5, which indicates that the lid 20 has been opened, that is, to prevent tampering. is there. As shown in FIG. 5, an auxiliary opening 15a is formed in the rising wall 12 located immediately below, so that the mark surface 15 is easily extended or cut when each rising wall 12 is pushed down. May be implemented. The auxiliary opening 15a is formed below the mark surface 15 of each rising wall 12, as shown in FIG.

In the packaging container 100 configured as described above, the rising wall 12 surrounding the knob 21
Is pressed down as shown in FIG. 4 to expose the tip of the knob 21 and the lid 20 is opened by lifting the knob 21. Therefore, as shown by the phantom line in FIGS. 3 and 4, a pulling portion 12a is formed in a part of the rising wall 12, and the pulling portion 12a is pushed down or pulled down to thereby raise the rising wall. 12 may be implemented to facilitate the downward movement.

Further, by pushing down each rising wall 12, the knob 21 is raised from below.
6 is more preferable. Such a raised portion 16 is formed as shown in FIG. That is,
As shown in FIG. 6 (a), a substantially central portion of the fold line 13 formed in the space bottom surface 11a is omitted, and a slit 16a which surrounds the omitted portion from the inside.
Is formed, and the inside of the slit 16a is set as the raised portion 16.

If such raised portions 16 are formed,
As shown in (b) of FIG. 6, if the tip of the rising wall 12 is pushed down, the space bottom surface 11a is bent around the fold curve 13 that has been left slightly, and is completely independent of the space bottom surface 11a by the slit 16a. The raised portion 16 that has been set up stands up. As a result, the lower surface of the knob 21 is pushed up by the tip of the raised portion 16, so that the knob 21 can be projected from the storage space 30 in order to facilitate opening of the lid 20. .

Of course, if the container body 10 is formed of a transparent synthetic resin material, the rising wall 12 is pushed up to raise the rising wall 12 and the space bottom surface 11a.
Since a cloudy portion is formed on itself, falsification can also be prevented by this.
