In the main body portion C, a front chamber rear wall 27 is disposed between the packaging container front wall 20 and the packaging container rear wall 32 so as to extend in parallel with these walls. The front space I on the packaging container front wall 20 side (front side) and the rear space J on the packaging container rear wall 32 side (rear side) are roughly divided in the front-rear direction. The front chamber rear wall 27 is a partition wall that partitions the accommodation space H (the main body C, in other words, the inside of the packaging container A). The front space I and the rear space J are box-shaped spaces that are flat in the front and rear and have substantially the same size. The front space I and the rear space J communicate with each other at a position above the front chamber rear wall 27. The locking piece 30 of the front chamber rear wall 27 is folded back toward the rear space J.

The upper end of the storage space H is opened upward as a horizontally-long rectangular take-out port K that is partitioned from the lateral direction by the upper end edges of the packaging container left side wall 22 and the packaging container right side wall 23. The takeout port K is continuous with the takeout window G when the takeout window G is formed on the packaging container front wall 20 (see FIG. 2).
In the front space I which is substantially the front half of the housing space H, the lower end is closed by the front chamber bottom wall 24, and the upper end is opened upward as a substantially front half of the takeout port K. Moreover, when the extraction window G is formed, the upper part of the front space I is opened forward from the extraction window G (see FIG. 2).

Here, the packaging container front wall 20, the front chamber rear wall 27 and the front chamber bottom wall 24 that divide the front space I in the accommodation space H, and the substantially front half of each of the packaging container left side wall 22 and the packaging container right side wall 23. The group constitutes the front chamber L. In addition, the front chamber L may include the substantially rear half of each of the packaging container left side wall 22 and the packaging container right side wall 23 and the packaging container rear wall 32. In this case, the entire main body C is the front chamber L.
In the rear space J of the substantially rear half of the storage space H, the lower end of the insertion space M (a later-described figure) having a lower end defined by the lower end edges of the front chamber rear wall 27 and the packaging container rear wall 32 in the front-rear direction. 8 (e)), and the upper end thereof is opened upward as a substantially rear half of the takeout port K. That is, the rear space J is a space between the front chamber rear wall 27 and the packaging container rear wall 32 that is open at the top and bottom.

FIG. 8 shows a six-sided view of the main body C.
FIG. 9 is an exploded perspective view for explaining a state in which the rear chamber B is combined with the main body C. FIG. 10A is a perspective view of the packaging container A, showing a state where the lid 4 is opened before sealing, and FIG. 10B is a right side of the packaging container A of FIG. It is sectional drawing.
With reference to FIG. 9, the packaging container A is completed by combining the rear chamber B and the main body C assembled as described above. In the packaging container A, for example, six food units 42 are accommodated in two rows in the front-rear direction.

The food unit 42 is a product in which gum as a plate-shaped small piece of food is wrapped in wrapping paper and individually wrapped. For example, a plurality of food units 42 are accommodated in the accommodation space E of the rear chamber B in a state of standing side by side in the horizontal direction, and an adhesive (adhesive tape) is attached to the rear chamber rear wall 1 of the deployed rear chamber B. May be adhered). Similarly, a plurality of food units 42 are accommodated in the front space I of the front chamber L of the main body C in a state of standing in the horizontal direction, and the front chamber rear wall 27 of the front chamber L in the unfolded state It is glued. Of course, the food unit 42 may be accommodated without being bonded to the packaging container A.

First, as shown in FIG. 9, the lid 4 of the rear chamber B is opened. At this time, the lid 4 is extended upward from the upper edge (upper side 1U) of the rear chamber rear wall 1 and is substantially flush with the rear chamber rear wall 1.
In the packaging container A, the lid 4 extends from the upper edge of the rear chamber rear wall 1, but the rear chamber rear wall 1 extends along the packaging container rear wall 32 of the main body C, and the packaging container A Also functions as a rear wall. Therefore, it can be said that the lid 4 extends from the upper edge of the rear wall of the packaging container A.

Next, the take-out window D of the rear chamber B and the notch possible portion 61 of the main body C are directed in the same direction (front side in FIG. 9), and in this state, the rear chamber B is taken out from the outlet K of the main body C. It is inserted into the rear half part from above and moved to the back of the main body C.
Thereby, the rear chamber B is accommodated in the rear space J of the main body C. At this time, since the left and right stoppers 17 of the first lid portion 10 of the lid 4 are the largest in the lateral direction (wide) in the rear chamber B and the main body C, the stopper 17 is the packaging container of the main body C. The left side wall 22 and the packaging container right side wall 23 are in contact (engaged) from above with respect to the upper end edges on the same side on the left and right. Accordingly, the rear chamber B is restricted from moving downward in the rear space J, and can be prevented from falling off from the insertion port M on the bottom side of the main body C.

Referring to FIG. 10, immediately after the rear chamber B is inserted into the rear space J of the main body C in this manner, the lid 4 is open and is moved upward from the upper edge (upper side 1U) of the rear chamber rear wall 1. It is in a state extending toward the. Therefore, the upper side 1U of the rear chamber rear wall 1 is folded, and the lid 4 is folded forward so as to be orthogonal to the rear chamber rear wall 1. Further, in the lid 4, the first folding guide 12 is folded and the first folding guide 12 is folded. 2 The lid portion 11 is bent downward so as to be orthogonal to the first lid portion 10. Thereby, the lid | cover 4 will be in the closed state, as shown in FIG.

Referring to FIG. 1, in the closed state, the lid 4 constitutes a flap. In the lid 4, the first lid part 10 covers the upper part of the packaging container A, and the second lid part 11 covers the front upper part of the packaging container A (the upper part of the packaging container front wall 20). Therefore, the takeout port K of the main body C located at the top of the packaging container A is closed by the first lid 10. In other words, the first lid 10 constitutes the upper wall of the packaging container A. In this case, since it is not necessary to provide a flap in both the front chamber L and the rear chamber B in order to cover the upper part and the front upper part of the packaging container A, the number of parts can be reduced.

The lid 4 closed in this way is adhered to the notch possible portion 61 of the packaging container front wall 20 of the main body C with an adhesive 63 as an adhesive means. In this state, the packaging container A is sealed.
Specifically, the adhesive 63 is configured by a double-sided adhesive sheet interposed between the lid 4 and the notchable portion 61. This double-sided adhesive sheet is obtained by applying an adhesive on both sides of a thin resin sheet.
In the sealed state, the main body portion 60 and the notch-possible portion 61 are connected to each other, and the notch-possible portion 61 and the lid 4 are bonded to each other.

In order to open the packaging container A, the lid 4 may be pulled up by holding the tip edge 11A of the lid 4.
Referring to FIG. 2, when lid 4 is lifted, notchable portion 61 is pulled by lid 4, and breakage occurs along perforation line 62. Separated from the container front wall 20. Thereby, the take-out window G is surrounded by the main body portion 60 of the packaging container front wall 20 and is formed to have substantially the same size as the take-out window D (see FIG. 4) of the rear chamber front wall 16. On the back surface of the lid 4, the cutout possible part 61 is left as it is.

With reference to FIG. 1A and FIG. 2A, as described above, a perforation line 62 as a separation processing line is provided, and the upper part of the packaging container front wall 20 adhered to the lid 4 is opened. By being separable from the packaging container front wall 20, it is possible to realize the paper packaging container A having a function of preventing tampering with respect to the sealing of the lid 4.
Therefore, if the lid 4 is opened at the time of opening, the notchable portion 61 on the upper part of the packaging container front wall 20 of the main body C is cut off and the take-out window G appears. It is easy to see that it is done. That is, when the lid 4 closed after opening is opened, the notchable portion 61 of the packaging container front wall 20 is not cut off, so that it can be easily understood that the lid 4 has been opened.

Further, when the lid 4 is opened at the time of opening, the upper part of the packaging container front wall 20 is separated from the packaging container front wall 20 and opened together with the lid 4, and a takeout window G appears on the upper part of the packaging container front wall 20. . When the lid 4 is opened, the takeout window G appears, so that the food unit 42 accommodated therein can be taken out easily. Furthermore, by providing the packaging container A body with a function to prevent tampering, there is no need to wrap the entire packaging container from the outside with a transparent film such as polypropylene as in the prior art, thereby improving productivity and reducing manufacturing costs. be able to.

As the separation processing line, a perforation line 62 having short cuts intermittently formed in the packaging container front wall 20 is preferable. That is, the perforation line 62 can be easily processed and can be easily separated.
As an adhesive means for adhering the lid 4 and the notchable portion 61 to each other, it is preferable to use a double-sided adhesive sheet. Thereby, an adhesive agent is easy to handle and the notch possible part 61 and the lid | cover 4 of the packaging container front wall 20 can be adhere | attached easily.

FIG. 11A is a perspective view of the packaging container A and shows a state in which the lid 4 is opened after sealing and the rear chamber B is pulled up with respect to the main body C. FIG. FIG. 12 is a right side sectional view of the packaging container A of FIG. FIG. 12 is a perspective view of the opened packaging container A with the lid 4 closed. FIG. 13 is a perspective view of a state in which the rear chamber B is taken out from the packaging container A and the lid 4 is closed in the rear chamber B. FIG. 1, 2, and 9 to 13, the front side of the paper is the front side of the packaging container A, and the back side of the paper is the rear side of the packaging container A.

2 and 11, with the lid 4 opened, the rear chamber B with respect to the main body C is in the upper position shown in FIG. 11 (b) and the lower position shown in FIG. 2 (b). Can be slid between.
As shown in FIG. 2 (b), the upper edge of the front extending plate 8 on the rear chamber front wall 16 on the rear chamber B side in the lower position is the locking piece 30 of the front chamber rear wall 27 on the main body C side. (Strictly speaking, it is opposed from the bottom with a predetermined distance to the folded back locking piece 30 and the vicinity of the connecting portion between the front chamber rear wall 27).
As shown in FIG. 11 (b), the upper edge of the front extended plate 8 on the rear chamber B side in the upper position is the locking piece 30 on the front chamber L side (strictly speaking, the folded locking piece 30 and By being locked from the lower side with respect to the connecting portion with the front chamber rear wall 27, the upward sliding of the rear chamber B is limited to a predetermined amount Z.

By setting the upper position shown in FIG. 11, the rear chamber B and the front chamber L are arranged in steps, and the upper end portion of the rear chamber B protrudes from the front chamber L, so that the food unit 42 can be easily taken out from the rear chamber B. it can.
For the upper position, only the rear chamber B (for example, the lid 4) is grasped and pulled upward. Alternatively, the rear chamber bottom wall 5 exposed from the insertion port M of the main body C may be pushed up.
As described above, the rear chamber B is combined with the front chamber L so as to be slidable upward by a predetermined amount Z with respect to the front chamber L. Therefore, the rear chamber is provided only when necessary even if a bottom raised portion is provided on the rear side of the packaging container A in advance and the gum in the rear row (rear chamber B) is not positioned higher than the gum in the front row (front chamber L). If B is slid upwardly relative to the front chamber L, the gum in the rear row can be arranged at a higher position than the gum in the front row (see FIG. 11). Thereby, since it is not necessary to provide the said bottom raising part, size reduction of the packaging container A can be achieved.

That is, in this packaging container A, it is possible to achieve both ease of picking out each food stored in a plurality of rows in the front and rear and downsizing of the container.
To close the packaging container A, the rear chamber B is set to the lower position, and the rear chamber B (portion other than the lid 4) is completely accommodated in the rear space J of the main body C, and the second lid 11 of the lid 4 The extraction window G is covered (see FIG. 12). At this time, the left and right stoppers 17 of the first lid portion 10 of the lid 4 come into contact with the left and right sides of the packaging container left side wall 22 and the packaging container right side wall 23 of the main body C from the upper side. It is possible to prevent the rear chamber B accommodated in the space J from falling out of the insertion port M on the bottom side of the main body C.

Further, the extraction window G in the upper part of the packaging container front wall 20 is closed by the second lid portion 11. And the center part of the front-end | tip edge 11A of the 2nd cover part 11 is engaged with the packaging container front wall 20 so that the cover 4 may not remove | deviate by inserting in the notch 21 of the packaging container front wall 20. FIG. Thereby, the closed state of the lid 4 is maintained.
As shown in FIG. 13, only the rear chamber B may be taken out from the main body C. The rear chamber B forms a packaging container that can be used independently by releasing the combination with the main body C (front chamber L). Therefore, when the front chamber L becomes dead space after eating the food (gum) contained in the front chamber L, the rear chamber B is removed from the front chamber L, and the remaining gum is removed from the rear chamber. In the state accommodated in B, it can be carried compactly with a thickness approximately half that of the original packaging container A. That is, when a part of the plurality of gums is eaten, the packaging container A can be reduced in size (thinned) and reused, which is convenient.

Here, in order to cancel the combination of the rear chamber B and the main body C, for example, the rear chamber B is pulled out from the main body C against the locking by the stopper 17 or the locking piece 30, It is conceivable to take out the rear chamber B by breaking a part of C. For this purpose, a separation line such as a perforation line for breaking the main body C may be formed.
In addition, the rear chamber B in a single product state that is released from the combination with the main body C can be closed using the lid 4. That is, the folding at the first folding guide 12 of the lid 4 is excluded. That is, the folding between the second piece 15 that is the front portion of the first lid 10 (the portion that was the upper wall of the packaging container A) and the second lid 11 that is the flap of the packaging container A is excluded. . Thereby, the 1st cover part 10 and the 2nd cover part 11 become flush.

Next, the second fold guide 13 is creased (along the second fold guide 13), and the second piece 15 and the second lid portion 11 are placed on the front lower side so as to be orthogonal to the first piece 14. Bend to. As a result, the lid 4 is in a closed state as shown in FIG. In this state, in the lid 4, the first piece 14, which is the rear portion of the first lid portion 10, becomes the upper wall of the rear chamber B, and the second piece 15 and the second lid portion 11 are flaps that cover the front of the rear chamber B. Function as.
Thus, the lid 4 of the rear chamber B becomes a flap of the entire packaging container A when the rear chamber B is combined with the front chamber L (see FIG. 12), and the rear chamber B is separated from the front chamber L. If it is independent, it becomes the flap of the rear chamber B (see FIG. 13). For this reason, it is not necessary to separately provide a flap portion of the entire packaging container A and a flap portion of the rear chamber B, so that the number of parts can be reduced.

In the state where the lid 4 is closed in the rear chamber B in a single product state, the first piece 14 of the first lid portion 10 of the lid 4 covers the upper portion of the rear chamber B, and the second piece 15 and the second lid portion 11 are The front upper portion of the rear chamber B (the upper portion of the rear chamber front wall 16) is covered. Therefore, the take-out port F at the upper part of the rear chamber B is closed by the first piece 14, and the take-out window D at the upper part of the rear chamber front wall 16 has the second piece 15 and the second lid portion 11. It is blocked by. For this reason, when the rear chamber B is used independently, the lid 4 covers the front and upper sides of the rear chamber B, so that food stored in the rear chamber B can be prevented from spilling out to the front outer side.

Then, by inserting the center portion of the leading edge 11A of the second lid portion 11 into the notch 9 of the rear chamber front wall 16, the lid 4 is engaged with the rear chamber front wall 16 so that the lid 4 does not come off, and the lid 4 is closed. State is maintained. Moreover, the food unit 42 can be pulled out upward from the take-out port F by removing the leading edge 11A of the second lid 11 from the notch 9 in the rear chamber front wall 16 and opening the lid 4.
As described above, the main body C is divided into the front chamber L and the rear chamber B, and a take-out window G is formed in the front wall 20 of the packaging container of the front chamber L. It is possible to move upward. Thereby, it is easy to align the food stored inside the main body C, and the food unit 42 can be easily taken out from the front chamber L and the rear chamber B.

Moreover, the rear chamber B can form the packaging container which can be used independently by canceling | releasing the combination with the front chamber L. FIG. In this case, for example, when the front room L becomes empty, the front room L can be discarded and only the rear room B can be used.
The present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the claims.

For example, in the first embodiment, the following modifications can be considered. For example, in the packaging container A, the food units 42 are accommodated in two rows in the front and rear as a whole by accommodating the food units 42 in the front chamber L and the rear chamber B (see FIG. 2). Instead of this, by providing a plurality of rear chambers B, the food units 42 may be accommodated in three or more rows. In this case, it is preferable that the food units 42 in each rear chamber B can be easily extracted by pulling the plurality of rear chambers B upward in a stepped manner. Moreover, the number of the food units 42 accommodated in each of the front chamber L and the rear chamber B can be changed as appropriate.

Further, as a method of closing the lid 4, not only a method of inserting the leading edge 11 A of the second lid part 11 into the

notches

9 and 21, but also a mountain-shaped notch at the center of the second lid part 11 or a position near the leading edge 11 A. Alternatively, a method of engaging the notch with the

notches

9 and 21 may be used. Moreover, the shape of the

notches

9 and 21 is not limited to the substantially U shape shown in FIGS. 4 and 7, but is substantially U shape that is upside down, substantially V shape, substantially M shape, and lateral direction. It is also possible to use a straight line shape extending in a straight line.

In addition, as a combination method of the rear chamber B and the main body C (front chamber L) (a method for producing the packaging container A), in the main body C, the left extending plate 25 and the right extending plate 26 are not bonded, The rear chamber B may be accommodated in the rear space J and combined with the main body C, and then the left extending plate 25 and the right extending plate 26 may be bonded to complete the packaging container A (see FIG. 1).
Moreover, although the double-sided adhesive sheet was used for adhesion | attachment of the lid | cover 4, as an adhesion | attachment means, it is not limited to this. For example, an adhesive such as a hot melt or a water-soluble adhesive may be applied to at least one of the opposing adhesive surfaces.

Moreover, as foodstuffs accommodated in the packaging container A, although not specifically limited, the plate-shaped elongate food | food packaged individually as mentioned above is preferable. Such plate-like longitudinal food may be chocolate or candy in addition to gum.
Further, in the packaging container A, the lid 4 is extended from the upper edge of the rear chamber rear wall 1, but may be extended from the upper edge of the packaging container rear wall 32 of the main body C. However, in that case, it is necessary to separately provide a knob portion so that the rear chamber B can be easily pulled out or pushed down. Moreover, although not shown in figure, the packaging container which can be utilized independently (specifically, the rear chamber B of a single state) may be provided with the above-mentioned falsification preventing function.

These modifications of the first embodiment can also be applied to second to fourth embodiments described below.
The second embodiment differs from the first embodiment in the following points, and other points are configured in the same way. Below, it demonstrates focusing on a different point. In addition, about the component of each following embodiment, about the component which has the same function as 1st Embodiment, the same name and code | symbol as the component of 1st Embodiment are attached | subjected, and the description is abbreviate | omitted.

FIG. 14 is a development view of the rear chamber B2 in the packaging container A2 according to the second embodiment of the present invention. FIG. 15 is a development view of the main body C2 in the packaging container A2.

The connection surface 71 is composed of a plurality of strip-shaped plates, and these plates are assembled so as to be bent and connected to each other at their long sides. Thereby, in the assembled state, the connection surface 71 forms a substantially curved surface. The packaging container front wall 20 and the packaging container right side wall 23 are connected via a connection surface 72 similar to the connection surface 71.
Note that the conventional falsification preventing method of packaging the entire packaging container from the outside with a transparent film such as polypropylene is not suitable for a packaging container having a substantially curved surface such as the packaging container A2 from the viewpoint of manufacturing suitability. . However, by providing the paper packaging container body with the function of preventing falsification as in the present invention, it is not necessary to wrap the entire packaging container from the outside with a transparent film as in the prior art. For this reason, it becomes possible to employ | adopt the packaging container which has a substantially curved surface like packaging container A2 as a packaging container of the product which has a falsification prevention function.

Moreover, the dimension of the packaging container front wall 20 of the main-body part C2 is made narrower than the width | variety of the rear chamber front wall 16 about the left-right direction of packaging container A2 in the assembled state.
You may apply the structure for making the corner | angular part of the right-and-left both-sides edge of the front surface of packaging container A2 into a curved shape to 1st Embodiment and each embodiment mentioned later.
FIG. 17 is a development view of the rear chamber B3 in the packaging container A3 according to the third embodiment of the present invention. FIG. 18 is a development view of the main body C3 in the packaging container A3. FIG. 19 is an exploded perspective view for explaining a state in which the rear chamber B3 is combined with the main body C3. FIG. 20A is a right side sectional view of the packaging container A3 in a state where the lid 4 is opened and the rear chamber B3 is in the lower position, and FIG. 20B is a diagram showing the lid 4 opened and the rear chamber B3. It is right side sectional drawing of the state which is in an upper position. FIG. 21 is a perspective view of the main part of the packaging container A3 with the lid 82 of the dust chamber 81 open. 22A is a right sectional view of the main part of the packaging container A3 with the lid 82 of the dust chamber 81 open, and FIG. 22B is a packaging with the lid 82 of the dust chamber 81 closed. It is right side sectional drawing of the principal part of container A3.

First, referring to FIG. 19, the packaging container A3 has a main body C3 and a rear chamber B3. The packaging container A3 has a vertically long box shape that is flat in the front-rear direction. However, the roundness of the left and right corners on the front surface as in the second embodiment is not formed. A dust chamber 81 is provided below the packaging container A3, that is, below the accommodation space H. The dust chamber 81 can be opened and closed with a lid 82. For example, in the dust chamber 81, it is possible to store used packaging materials removed from the food, and unusable items such as gum after chewing. Note that the dust chamber 81 is not limited to an unneeded item, and may be used as a storage chamber that can also store other articles.

FIG. 19 shows a case where four food units 42 are accommodated in the front and rear two rows in the packaging container A3.
Referring to FIG. 17, rear chamber B3 is formed by assembling paper pattern X3. The rear chamber rear wall 1 is formed in a vertically long rectangular shape. In the rear chamber rear wall 1, an inverted U-shaped cut 83a for forming a cut-and-raised locking piece 83 is formed. The part surrounded by the notch 83a is folded back, whereby the locking piece 83 is formed. The tip end edge 11A of the second lid portion 11 extends straight from side to side. The notch 9 of the front extending plate 8 in the rear chamber B3 is formed in a substantially M shape.

Referring to FIG. 18, the main body C3 is formed by assembling the pattern Y3. The packaging container rear wall 32 (the left extending plate 25 and the right extending plate 26) and the front chamber rear wall 27 of the main body C3 are formed in a vertically long rectangular shape.
The main body C3 in the state of the pattern Y3 has a packaging container front wall 20 that is substantially vertically long. In the assembled state, an extraction window G (see FIG. 18) is formed on the top of the packaging container front wall 20. The extraction window G is formed in the same size as the extraction window D (see FIG. 17) of the rear chamber front wall 16. The cut 21 in the packaging container front wall 20 is formed in a substantially M shape.

In addition, the shape of the

notches

9 and 21 is not limited to a substantially M shape, but may be a substantially M shape that is upside down, a substantially V shape, a substantially U shape, a linear shape that extends in the lateral direction, or the like. It is also possible.
A rectangular cutout 84 is formed in the packaging container right extending plate 26. As shown in FIG. 20, in a state where the packaging container A3 is assembled, the notch 84 and the locking piece 83 (see FIG. 17) formed on the rear chamber rear wall 1 face each other in the vertical direction. Are arranged to be engageable with each other.

As shown in FIG. 20B, when the rear chamber B3 is in the upper position, the lower edge of the notch 84 and the locking piece 83 are separated from each other vertically. As shown in FIG. 20A, when the rear chamber B 3 is in the lower position, the lower edge portion of the notch 84 engages with the lower edge of the locking piece 83. Specifically, the notch 84 receives the locking piece 83, and the lower edge portion of the notch 84 comes into contact with and receives the lower edge of the locking piece 83. As a result, the slidable lower position of the rear chamber B3 is restricted, and the rear chamber B3 is prevented from entering the dust chamber 81.

Since the lower edge of the notch 84 and the lower edge of the locking piece 83 are engaged and the downward sliding of the rear chamber B3 is restricted, the left and right stoppers 17 of the first lid portion 10 are not necessarily provided. It does not have to be provided.
With reference to FIG. 18 and FIG. 20A, the front chamber bottom wall 24 is connected to the lower side 20D of the packaging container front wall 20 via the folded portion 85 in the main body C3 in the developed view. When assembled, the folded portion 85 is folded at the lower side 20D of the packaging container front wall 20, and the folded portion 85 and the back surface of the packaging container front wall 20 are bonded to each other. The adhesive is a predetermined region of at least one of the folded portion 85 and the back surface of the packaging container front wall 20 (a region indicated by a dashed-dotted rectangle in FIG. 18, and both regions are illustrated in FIG. 18. .).

You may apply the structure regarding the dust chamber 81 of packaging container A3 to 1st and 2nd embodiment and embodiment mentioned later.
FIG. 23 is a perspective view of the packaging container A4 according to the fourth embodiment of the present invention, and shows a state in which the lid 4 is opened before sealing. FIG. 24 is a perspective view of the packaging container A4 and shows a state where the lid 4 is closed and sealed. FIG. 25 is a perspective view of the packaging container A4 and shows a state in which the lid 4 is opened after sealing.

The packaging container A4 has a main body C4 and a rear chamber B. The main body C4 is obtained by forming a take-out window G in a pattern paper (not shown) in the main body C described above. The packaging container front wall 20 of the main body C4 is formed in a U shape in the same shape as the main body 60 (see FIG. 2).
That is, an extraction window G as an opening that appears when the lid 4 is opened is formed on the upper front surface of the packaging container front wall 20 of the main body C4. As shown in FIG. 23, the take-out window G is covered with a film sheet 95 before opening.

The film sheet 95 is a thin film made of synthetic resin. Further, the film sheet 95 is formed larger than the take-out window G so that a required bonding margin can be secured around the take-out window G in the packaging container front wall 20. Further, the film sheet 95 may be formed to have the same size as or larger than the back surface of the lid 4, but is preferably formed smaller than the lid 4 so as not to protrude from the lid 4.
23 and 24, in the sealed state, the film sheet 95 and the upper front surface of the packaging container front wall 20 are bonded together by an adhesive 96 interposed therebetween. Further, the film sheet 95 and the back surface of the lid 4 are bonded by an adhesive 97 interposed therebetween. Specifically, the adhesive 96 and the adhesive 97 are configured by the double-sided adhesive sheet described above. As the

adhesives

96 and 97, hot melt, water-soluble adhesive, or the like may be used. For example, the adhesive force of the adhesive 97 that bonds the film sheet 95 and the back surface of the lid 4 is set to be stronger than the adhesive force of the adhesive 96 that bonds the film sheet 95 and the front surface of the packaging container front wall 20. .

Thereby, when the lid 4 is opened and opened, as shown in FIG. 25, the film sheet 95 together with the lid 4 is removed from the upper front surface of the packaging container front wall 20 (specifically, the peripheral portion of the extraction window G), An extraction window G appears.
Further, the adhesive strength of the

adhesives

96 and 97 is set so as to be remarkably reduced when peeled off after the adhesion. The film sheet 95 peeled off at the time of opening cannot be reattached to the packaging container front wall 20.

As described above, the paper packaging container A4 having a function of preventing falsification can be realized by the film sheet 95 and the

adhesives

96 and 97 covering the extraction window G. For example, when the lid 4 is opened, the film sheet 95 is peeled off from the packaging container front wall 20 and the take-out window G appears. Therefore, even if the lid 4 is closed after that, it is easily understood that it has been opened. .
Further, it is preferable that the take-out window G and the film sheet 95 covering the take-out window G are provided so as not to be obstructed by the cover 4 when the cover 4 is closed and overlaps the packaging container front wall 20. In this case, the appearance of the packaging container A4 with the lid 4 closed can be improved.

The film sheet 95 may be a thin paper or a metal foil such as an aluminum foil. Furthermore, the adhesive 96 may be designed to have a strong adhesive force so that when the lid 4 is opened and opened, a part of the film sheet 95 is torn and remains adhered to the packaging container front wall 20.
In addition, you may apply the structure regarding the falsification prevention function of packaging container A4 to each above-mentioned embodiment.
In addition, various design changes can be made within the scope of the matters described in the claims.
