Description

[0001]
[Industrial application fields]
The present invention relates to a packaging container comprising a container body formed of a synthetic resin as a material and a lid fitted to the container body. In particular, once opened, it is prevented from being tampered with where it remains somewhere. It relates to a packaging container.
[0002]
[Prior art]
Packaging containers that are hermetically sealed by fitting a lid inside or outside into an opening of a container body that contains food such as candy and lunch boxes are currently in various forms. Things have been proposed. Among them, the type in which the lid is externally fitted or internally fitted with respect to the container main body, the outer periphery thereof may not be further wrapped with a wrap or film, since it can have sealing properties, It is often produced by integral molding using synthetic resin as a material mainly by means such as injection molding.
[0003]
However, in packaging containers in which the lid is fitted in or out of the container body, they are often arranged as they are in the store, and it is easy for tampering and tampering such as removing the lid. Because of such mischief and tampering, packaging containers and stored items that have been opened once have no value as products, so such items must be easily found by visual inspection. .
[0004]
As a conventional method that makes it easy to visually detect such tampering, for example, a seal that is torn if the seal is released is attached to the boundary between the container body and the lid, or opened. There are various things such as sticking a sticker that cannot be repaired easily. However, preparing such a seal and sticking it to a packaging container after the contents are packed is in a situation where a large facility is separately provided or manual work must be relied upon.
[0005]
However, it is very difficult to introduce equipment for sticking stickers for this type of packaging container, which has a variety of container sizes and shapes. It is not supposed to be.
[0006]
Therefore, the present inventor has completed the present invention as a result of various studies on whether or not tampering prevention can be easily performed.
[0007]
[Problems to be solved by the invention]
The present invention has been made on the basis of the above-described circumstances, and a problem to be solved is to provide a packaging container that can prevent tampering simply by fitting a lid to the container body. There is.
[0008]
That is, the object of the invention according to claim 1 is that the lid can be secured as it is by fitting the lid to the container body, and even if the lid is opened due to mischief or the like, the trace is not found. It is an object of the present invention to provide a packaging container with tampering prevention that can reliably remain tampered with and can be easily detected visually.
[0009]
Further, the object of the invention according to claim 2 is to provide a packaging container that can achieve the same object as in claim 1 and that can more reliably leave a trace when tampering is achieved. It is to provide.
[0010]
[Means for Solving the Problems]
In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the embodiments described later.
“It is a packaging container 100 comprising a container body 10 and a lid 20 having a knob portion 21 which is at least partially fitted therein and is positioned in the immediate vicinity of the inside fitting portion. And
A portion of the container body 10 in which at least a part of the lid 20 is internally fitted is surrounded by the rising wall 12 and forms a storage space 30 in which the knob portion 21 is stored.
When the knob portion 21 is stored in the storage space 30, an inward projection 14 that protrudes inwardly above the knob portion 21 is formed on the rising wall 12,
Furthermore, a tamper-proof packaging container 100, characterized in that a folding line 13 is formed on the bottom surface 11a of the space located between the rising walls 12 to make it easier to bend downward.
It is.
[0011]
That is, as shown in FIGS. 1 and 2, the packaging container 100 according to claim 1 includes a container body 10 and a lid body 20 fitted to the container body 10 so as to cover the upper opening thereof. The container body 10 has a storage space 30 in which the knob portion 21 on the lid 20 side is stored, as shown in an enlarged view in FIG. It is what. In order to configure the storage space 30, on the container body 10 side, as shown in FIG. 2, a space bottom surface 11a consisting of a part of the flange 11 and two rising walls surrounding it at an angle of 90 ° 12 are formed. Each of these rising walls 12 is integrally formed with an inward projection 14 as shown in FIGS.
[0012]
Now, when the lid 20 configured as described above is fitted into the container body 10 packed with food or other stored items, the knob 21 forms at least one corner of the flange 11 on the container body 10 side. It fits in the storage space 30 on the space bottom surface 11a. At this time, since the end edge of the knob 21 gets 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. 21 is below each inward protrusion 14 and is in close contact with the space bottom surface 11a. That is, the knob portion 21 on the lid 20 side is completely buried in the storage space 30 surrounded by the space bottom surface 11a and the two rising walls 12, and is completely invisible from the outside.
[0013]
The main packaging container 100 sealed as described above opens the lid 20 from the container body 10 as follows. That is, as shown in FIG. 4, when the rising wall 12 surrounding the space bottom surface 11 a is pressed downward with a finger, the space bottom surface 11 a bends at the portion of the folding line 13 formed on the wall, and is buried until then. The tip of the knob 21 that has been exposed is exposed. Therefore, the lid 20 is opened by placing a finger on the knob 21.
[0014]
If the above opening is mischievous and the lid 20 is re-fitted to the container body 10, each rising wall 12 is deformed especially on the extension line of the folding line 13 by the force when pressed. The original state as shown in FIG. 2 has not been restored. In addition, each rising wall 12 has an inward projection 14 that 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 marks generated at the previous opening remain on each rising wall 12, but also the space bottom surface 11 a is deformed by the folding line 13. Therefore, even if it is not as shown in FIG.
[0015]
Therefore, in the packaging container 100 of this first aspect, once the lid body 20 is opened, it remains on the space bottom surface 11a and the rising wall 12, so that this can be easily found visually, and is tampered with. The prevention function will be demonstrated.
[0016]
Now, in order to solve the above-mentioned problem, the means taken by the invention according to claim 2 is about the packaging container 100 according to claim 1,
“When the space bottom surface 11a is bent along the folding line 13 on the upper portion of the rising wall 12, a mark surface 15 is formed that is broken or stretched and serves as a mark for tampering.”
It is.
[0017]
That is, as shown in FIG. 5, the packaging container 100 according to claim 2 has a marking surface 15 formed on the upper portion of the rising wall 12, and the marking surface 15 is formed after the lid 20 is once opened. In FIG. 5, the elastic deformation region is completely extended as shown in FIG. 5A, or it is completely cut out as shown in FIG. 5B. 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 is done, the mark surface 15 does not return to its original shape as shown in FIG. It will be in a state.
[0018]
Therefore, in the packaging container 100 according to claim 2, once the lid 20 is opened, not only the space bottom surface 11a and the rising wall 12 are deformed, but also the mark surface 15 is extended or cut. As a result, deformation that does not return to the original occurs, so that tampering prevention can be surely achieved.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
Next, the invention according to each claim configured as described above will be described with reference to the packaging container 100 according to the embodiment shown in the drawings. FIG. 1 shows the container body 10 constituting the present invention. The state which is going to fit the cover body 20 is shown. And the storage space 30 in which the knob | pick part 21 by the side of the cover body 20 is accommodated is formed in the lower left part of the container main body 10 which comprises this packaging container 100 of FIG.
[0020]
The container body 10 and the lid body 20 are integrally formed by injection molding with a synthetic resin or vacuum formation with a synthetic resin sheet. In the embodiment shown in FIG. It is assumed that “inside fitting” is performed. That is, in this 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 periphery of the lid 20 is fitted inside the rising wall 12. It is a thing. Accordingly, the lid 20 is fitted to the container main body 10 without a gap in the space bottom surface 11a to be described later and a portion other than the storage space 30 thereabove, and there is no portion for opening the lid 20 at all. It has become. The fitting of the lid 20 to the container body 10 may be a so-called “outside fitting” as long as the storage space 30 in which the knob 21 on the lid 20 side is to be accommodated can be formed. It goes without saying that the inner fitting portion may be only around the knob 21.
[0021]
As shown in FIG. 1, the container body 10 has a flange 11 around the upper opening, and a part of the flange 11 has a space bottom surface 11 a for constituting the storage space 30. As shown in FIGS. 2 and 3, the space bottom surface 11a has a substantially triangular shape. In addition, in the container main body 10 of this embodiment, it is assumed that it has the rounded corner part other than the space bottom face 11a.
[0022]
In the packaging container 100 of the present embodiment, the lid 20 is fitted inside the container body 10, so that the rising wall 12 as shown in FIG. 2 is integrally formed around the flange 11. It is. For this reason, in particular, the space bottom surface 11a is surrounded by two rising walls 12 orthogonal to each other as shown in FIG. 2, and the space bottom surface 11a and the rising wall 12 described above are described above. A storage space 30 is formed.
[0023]
As shown in FIG. 2, a folding line 13 is formed on the space bottom surface 11a exposed in the storage space 30. As shown in FIG. This folding line 13 is to be able to push down the space bottom surface 11a ahead and the part of the rising wall 12 integrated with the space bottom surface 11a downward separately from the others, The small openings 13a as shown in FIG. 2 are formed by being continuous like so-called “perforations”. Of course, each small opening 13a may be formed as a dent. Moreover, you may form only one each small opening part 13a and the dent corresponding to this between the two standing walls 12 which mutually cross | intersect.
[0024]
As shown in FIGS. 2 and 3, a substantially triangular knob 21 formed at one corner of the lid 20 is locked to the rising wall 12 positioned above the folding line 13. The inward projection 14 is formed. The height of the inward projection 14 is about 0.3 to 0.5 mm. However, when the container body 10 is molded, there is no obstacle and the shape changes depending on the molding. It does n’t matter. On the other hand, the crossing angle of the rising walls 12 rising on both sides of the space bottom surface 11a for forming the storage space 30 is set to 90 °, while the knob portion on the side of the lid 20 stored between them. The knob 21 that is pushed into the storage space 30 is surely stopped by the two inward projections 14 so that the top 21 has a 90 ° triangular shape. In addition, the shape of the storage space 30 and the knob | pick part 21 may be elliptical shape etc. other than what was demonstrated above.
[0025]
The inward projection 14 is formed so as to be above the folding line 13 in FIG. 2, but may be formed anywhere as long as the knob 21 of the lid 20 can be stopped. In particular, when the mark surface 15 as shown in FIG. 5 is formed on the upper portion of the rising wall 12, the inward projection 14 is preferably formed at a position where it does not interfere with the mark surface 15.
[0026]
When the two rising walls 12 enclosing the knob portion 21 are pushed down, the mark surface 15 extends greatly as shown in FIG. 5 (a) or is cut as shown in FIG. 5 (b). This indicates that the lid 20 has been opened, that is, to prevent tampering. In order to make it easy for the mark surface 15 to extend or break when the rising walls 12 are pushed down, as shown in FIG. 5, an auxiliary opening 15a is formed in the rising wall 12 located immediately below the rising surfaces 12. May be implemented. As shown in FIG. 1, the auxiliary opening 15 a is formed in a portion below the mark surface 15 of each rising wall 12.
[0027]
In the packaging container 100 configured as described above, the leading end of the knob 21 is exposed by pushing down the rising wall 12 surrounding the knob 21 as shown in FIG. The lid 20 was opened by lifting. Therefore, as shown by the phantom lines in FIG. 3 and FIG. 4, a pulling wall 12a is formed on a part of the rising wall 12, and the rising wall 12a is pushed down or pulled down. 12 may be implemented so as to facilitate downward movement.
[0028]
Further, it is more preferable to form the raised portion 16 that raises the knob portion 21 from below by pushing down each rising wall 12. Such a raised portion 16 is formed as shown in FIG. That is, as shown in FIG. 6A, a substantially central portion of the folding line 13 formed on the space bottom surface 11a is omitted, and a slit 16a is formed so as to surround the omitted portion from the inside. The inside of the slit 16a is a raised portion 16.
[0029]
If such a raised portion 16 is formed, as shown in FIG. 6B, if the leading end of the rising wall 12 is pushed down, the space bottom surface 11a is formed around the folding line 13 that is left a little. And the raising portion 16 that is completely independent of the space bottom surface 11a is raised by the slit 16a. As a result, the lower surface of the knob 21 is pushed up by the tip of the raised portion 16, and the knob 21 can be protruded from the storage space 30 in order to facilitate the opening of the lid 20. .
[0030]
Of course, if the container body 10 is formed of a transparent synthetic resin material, the rising wall 12 is pushed up, and a cloudy portion is formed on the rising wall 12 and the space bottom surface 11a itself. This can prevent tampering.
[0031]
