The locking piece 30 has a lateral isosceles ladder shape in which the perforated eye line 31 is a lower bottom, and is tapered toward the upper bottom side (the side from the perforated eye line 31 in Fig. 6). The locking tab 30 can also be considered as part of the anterior chamber posterior wall 27.

In this paper type Y, the left side wall 22 of the packaging container (left extension plate 25), the right side wall 23 of the packaging container (right extension plate 26), the front chamber bottom wall 24 (front chamber rear wall 27, locking piece) 30) The side of the left side 20L, the right side 20R, and the lower side 20D of the front wall 20 of the packaging container is creased and bent toward the same side (the back side of the paper in Fig. 6) so as to be orthogonal to the front wall 20 of the packaging container.

Then, the front chamber rear wall 27 (the locking piece 30) is creased at the lower end edge 24D of the front chamber bottom wall 24, and is bent upward so as to be orthogonal to the front chamber bottom wall 24. Then, the front chamber rear wall 27 (the locking piece 30) is opposed to the packaging container front wall 20 with a gap from the back side (rear side). At this time, the front end edge 27A of the front chamber rear wall 27 becomes the upper edge of the front chamber rear wall 27.

Then, the locking piece 30 is folded in a direction (rearward) from the front wall 20 of the packaging container with the perforated eye line 31 in the front end edge 27A as a crease.

Then, the left extension plate 25 and the right extension plate 26 are creased toward each other with the corresponding end edge of the left end edge 22L of the left side wall 22 of the packaging container and the right end edge 23R of the right side wall 23 of the packaging container. The inner side of the direction is bent so as to be orthogonal to the left side wall 22 of the packaging container and the right side wall 23 of the packaging container. Therefore, the right end portion of the bent left extension plate 25 (the left end portion before the bending of FIG. 6) overlaps with the right extension plate 26 from the rear side, and the left extension plate 25 and the right extension plate 26 are opposed to each other. The front chamber rear wall 27 and the refolded locking piece 30 are opposed to each other with a gap therebetween. In this state, by pasting the overlapping portion of the left extension plate 25 and the right extension plate 26, The body portion C is formed as shown in FIG.

In the main body portion C, the left-side extension plate 25 and the right extension plate 26 are integrally formed to constitute a packaging container rear wall 32 having a laterally rectangular shape. The packaging container rear wall 32 is the same size as the left extension plate 25.

In the main body portion C, as described below, the main body portion 60 of the front wall 20 of the packaging container and the cuttable portion 61 are connected to each other in a state before being opened (sold state) to form a single plate shape. Further, at the time of opening, the cleavable portion 61 is cut from the front wall 20 of the packaging container to form the take-out window G.

The main body portion C has a front wall 20 of the packaging container (to a rectangular sheet which is integrated with the main body portion 60 and the cuttable portion 61 before forming the take-up window G), the rear wall 32 of the packaging container, the left side wall 22 of the packaging container, and the packaging The accommodating space H surrounded by the right side wall 23 of the container has a flat box shape in the front-rear direction (the opposing direction of the front wall 20 of the packaging container and the rear wall 32 of the packaging container). The front side of the paper surface in Fig. 7 is the front side of the main body portion C, and the inner side of the paper surface in Fig. 7 is the rear side of the main body portion C. In the main body portion C, a front chamber rear wall 27 is disposed between the front wall 20 of the packaging container and the rear wall 32 of the packaging container so as to extend parallel to the walls, whereby the receiving space H is roughly divided into front and rear. The front space 20 side (front side) of the packaging container has two spaces before the space I and the rear side 32 (rear side) of the packaging container. The front chamber rear wall 27 is a partition wall that partitions the accommodating space H (the body portion C, in other words, the inside of the packaging container A). The front space I and the rear space J are substantially the same size in the box shape of the front and rear flat. The front space I and the rear space J communicate with each other at a position above the front side rear wall 27. Further, the locking piece 30 of the front chamber rear wall 27 is folded back toward the rear space J side.

The upper end of the accommodating space H is opened upward as a laterally-shaped outlet K which is divided by the upper end edges of the left side wall 22 of the packaging container and the right side wall 23 of the packaging container from the lateral direction. Taking the exit K when the take-up window G is formed on the front wall 20 of the packaging container, This take-out window G is continuous (refer to FIG. 2).

In the space I before the substantially front half of the accommodating space H, the lower end thereof is closed by the front chamber bottom wall 24, and the upper end thereof is opened upward as a substantially front half of the take-out port K. Further, the upper portion of the front space I is opened forward from the take-up window G when the take-out window G is formed (see FIG. 2).

Here, the combination of the packaging container front wall 20, the front chamber rear wall 27 and the front chamber bottom wall 24 of the front space I, and the substantially front half of the packaging container left side wall 22 and the packaging container right side wall 23 in the accommodating space H Forming the front chamber L. Furthermore, the front chamber L may also include the substantially rear half 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 main body portion C as a whole forms the front chamber L.

In the space J after the substantially rear half of the accommodating space H, the lower end serves as a laterally rectangular insertion opening M defined by the lower end edges of the front chamber rear wall 27 and the packaging container rear wall 32 from the front-rear direction (refer to FIG. 8 below). (e)) is opened downward, and its upper end is opened upward as a substantially rear half of the take-out port K. That is, the rear space J is a space opened up between the front chamber rear wall 27 and the packaging container rear wall 32.

Further, a six-sided view of the body portion C is shown in FIG.

FIG. 9 is an exploded perspective view for explaining a state in which the rear chamber B is combined with the main body portion C. Fig. 10 (a) is a perspective view of the packaging container A, showing a state in which the front cover 4 is opened, and Fig. 10 (b) is a right side sectional view of the packaging container A of Fig. 10 (a).

Referring to Fig. 9, the packaging container A is completed by combining the chamber B and the body portion C which are composed in the above manner. In the packaging container A, for example, six food units 42 are accommodated in each of the previous two rows.

The food unit 42 is packaged in a wrapper as a food product in the form of a sheet of chewing gum. For example, a plurality of food units 42 are accommodated in the accommodating space E of the rear chamber B in a state of being aligned in the lateral direction, by means of an adhesive (may also be The tape) is followed by the chamber back wall 1 after the chamber B after the unfolded state. Similarly, the plurality of food units 42 are accommodated in the space I before the main body portion C in a state in which they are arranged in the lateral direction and are erected, and are followed by the chamber rear wall 27 before the chamber L before the unfolded state. Of course, the food unit 42 can also be stored without being surrounded by 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 in a state of being 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.

Further, in the packaging container A, the cover 4 is extended from the upper edge of the rear chamber rear wall 1, but the rear chamber rear wall 1 is also applied as the rear wall of the packaging container A along the rear wall 32 of the packaging portion of the main body portion C. The function. Therefore, it can be said that the cover 4 is extended from the upper edge of the wall after the packaging container A.

Then, the take-out window D of the rear chamber B and the cut-away portion 61 of the main body portion C are oriented in the same direction (the front side in FIG. 9), and in this state, the rear chamber B is inserted from the upper side to the main body portion C. The rear half of the outlet K is moved toward the inner side of the body portion C.

Thereby, the rear chamber B is housed in the space J after the body portion C. At this time, since the left and right stopper portions 17 of the first lid portion 10 of the lid 4 are the largest (in the width direction) in the lateral direction in the rear chamber B and the body portion C, the stopper portion 17 is opposed to the body portion C. The upper end wall 22 of the packaging container and the right side wall 23 of the packaging container are abutted (engaged) from above at the upper end edges of the right and left sides. Thereby, the rear chamber B is restricted from moving downward in the rear space J, and it is prevented from falling off from the insertion opening M on the bottom side of the body portion C.

Referring to Fig. 10, immediately after the rear chamber B is inserted into the space J after the main body portion C in this manner, the lid 4 is immediately opened to a state in which the upper edge (upper side 1U) of the rear chamber rear wall 1 extends upward. Therefore, 1U is a crease on the upper side of the rear wall 1 of the room, and the cover 4 is bent forward so as to be orthogonal to the rear wall 1 of the rear chamber. Further, in the cover 4, the first folding guide 12 is used. The crease is formed so that the second cover portion 11 is orthogonal to the first cover portion 10 The style is bent downwards. Thereby, the cover 4 is in a state of being closed as shown in FIG.

Referring to Fig. 1, in the closed state, the cover 4 constitutes a cover. In the lid 4, the first lid portion 10 covers the upper portion of the packaging container A, and the second lid portion 11 covers the upper portion of the packaging container A (the upper portion of the front wall of the packaging container 20). Therefore, the outlet K of the main body portion C located at the upper portion of the packaging container A is closed by the first lid portion 10. In other words, the first cover portion 10 constitutes the upper wall of the packaging container A. In this case, in order to cover the upper portion and the upper portion of the front side of the packaging container A, it is possible to achieve the purpose without providing a cover for both the front chamber L and the rear chamber B, so that the number of parts can be reduced.

The cover 4 thus closed is then attached to the severable portion 61 of the front wall 20 of the packaging body by the adhesive 63 as an adhesive means. In this state, the packaging container A is sealed.

The adhesive 63 is specifically composed of a double-sided backing sheet interposed between the lid 4 and the cuttable portion 61. The double-sided back sheet is coated with an adhesive on both sides of a thin resin sheet.

In the sealed state, the main body portion 60 and the cleavable portion 61 are connected to each other, and the cleavable portion 61 and the lid 4 are mutually connected.

When the packaging container A is unsealed, the lid 4 can be pulled up by holding the front edge 11A of the lid 4.

Referring to Fig. 2, when the lid 4 is lifted up, the cutable portion 61 is pulled by the lid 4 and broken along the perforated eyeliner 62, and the cuttable portion 61 is cut from the front wall 20 of the packaging container. Thereby, the take-out window G is surrounded by the main body portion 60 of the front wall 20 of the packaging container, 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 inner surface of the lid 4, the cut portion 61 that has been cut is left as it is and remains.

Referring to Fig. 1 (a) and Fig. 2 (a), as described above, it is set as a cutting line The perforated eyeliner 62 can separate the upper portion of the front wall 20 of the packaging container with the cover 4 from the front wall 20 of the packaging container at the time of opening, thereby realizing a paper packaging having a tamper-proof function with respect to the sealing of the cover 4. Container A.

Therefore, if the lid 4 is opened at the time of opening, the cleavable portion 61 located at the upper portion of the front wall 20 of the packaging portion of the main body portion C is cut to cause the take-out window G, so that the lid 4 can be easily closed even after the lid 4 is closed. The ground is judged to have been opened. That is, when the lid 4 to be closed after opening is opened, the cuttable portion 61 of the front wall 20 of the packaging container is not cut, so that it is easy to judge that the lid 4 is opened.

Further, if the lid 4 is opened at the time of opening, the upper portion of the front wall 20 of the packaging container is separated from the front wall 20 of the packaging container and opened together with the lid 4, and a take-up window G is formed on the upper portion of the front wall 20 of the packaging container. Since the take-out window G is opened when the lid 4 is opened, it is easy to take out the food unit 42 accommodated inside. Further, by providing the tamper-proof function of the main body of the packaging container A, it is not necessary to package the entire packaging container from the outside by a transparent film such as polypropylene as in the prior art, and productivity improvement or manufacturing cost can be reduced.

As the cutting line, a perforated eyeliner 62 having a short slit intermittently formed in the front wall 20 of the packaging container is preferable. That is, the processing of the perforated eyeliner 62 is relatively easy, and the cutting is also easy.

As a means for adhering the cover 4 and the cuttable portion 61 to each other, it is preferable to use a double-sided back sheet. Thereby, the adhesive is easily handled, and the cuttable portion 61 of the front wall 20 of the packaging container and the lid 4 can be easily adhered to each other.

Figure 11 (a) is a perspective view of the packaging container A, showing the state in which the lid 4 is opened after sealing to raise the back chamber B relative to the body portion C, and Figure 11 (b) is the right side of the packaging container A of Figure 11 (a). View the section. Figure 12 is a perspective view showing a state in which the lid 4 is closed in the opened packaging container A. Figure 13 is in the back chamber B in the state where the chamber B is taken out from the packaging container A. A perspective view of the state in which the lid 4 is closed. Further, in the perspective views of Figs. 1, 2, and 9 to 13, the front side of the paper surface is the front side of the packaging container A, and the inner side of the paper surface is the rear side of the packaging container A.

Referring to FIGS. 2 and 11, in a state where the cover 4 is opened, the rear chamber B can be slid relative to the main body portion C between the upper position shown in FIG. 11(b) and the lower position shown in FIG. 2(b). .

As shown in Fig. 2(b), after the lower position, the upper edge of the front panel 16 in the chamber front side wall 16 is extended with respect to the front side wall 27 of the body portion C side (in strict terms , the adjacent portion of the connecting portion of the refastened locking tab 30 and the front chamber rear wall 27 is opposed to each other at a predetermined interval.

As shown in FIG. 11(b), the locking piece 30 of the upper edge of the plate 8 is extended with respect to the front chamber L side before the chamber B side (hereinafter, strictly speaking, the refastened locking piece 30) The portion connected to the front chamber rear wall 27 is locked from the lower side, thereby restricting the sliding of the rear chamber B upward to the predetermined amount Z.

By setting the upper position shown in FIG. 11, the rear chamber B and the front chamber L are arranged at different heights, and the upper end portion of the rear chamber B is protruded from the front chamber L, so that the food unit 42 can be easily taken out from the rear chamber B.

In order to be set to the upper position, only the rear chamber B (for example, the cover 4) is grasped and lifted upward. Alternatively, the insertion opening M of the body portion C may be exposed and then pushed up the chamber bottom wall 5.

As described above, the rear chamber B is slidable upward relative to the front chamber L, and is combined with respect to the front chamber L only in a predetermined amount Z. Therefore, even if the padding portion of the rear row (back chamber B) is disposed at a position higher than the chewing gum of the preceding row (front chamber L) without providing the padding portion on the rear side of the packaging container A, as long as it is only necessary when necessary The chamber B is slid upward with respect to the front chamber L, so that the subsequent chewing gum can be disposed at a position higher than the preceding chewing gum (refer to FIG. 11). With this, The object can be achieved without providing the above-mentioned padding portion, and therefore, the miniaturization of the packaging container A can be achieved.

In other words, in the packaging container A, it is possible to simultaneously realize the ease of pinching of the foods accommodated in the front and back of the plurality of rows and the miniaturization of the container.

When the packaging container A is closed, the rear chamber B is placed at the lower position, and the rear chamber B (the portion other than the cover 4) is completely accommodated in the space J after the main body portion C, and the second cover portion 11 of the cover 4 covers the take-out window. G (refer to Figure 12). At this time, since the left and right stopper portions 17 of the first lid portion 10 of the lid 4 abut on the left side of the packaging container left side wall 22 and the packaging container right side wall 23 on the right and left sides from the upper side, It is possible to prevent the insertion of the insertion opening M of the chamber B from the bottom side of the body portion C after being accommodated in the rear space J.

Further, the take-out window G located at the upper side portion of the front wall 20 of the packaging container is closed by the second lid portion 11. Further, by inserting the central portion of the front end edge 11A of the second lid portion 11 into the slit 21 of the front wall 20 of the packaging container, the lid 4 is engaged with the front wall 20 of the packaging container so as not to fall off. Thereby, the state in which the lid 4 is closed is maintained.

As shown in FIG. 13, only the rear chamber B can be taken out from the body portion C. The rear chamber B forms a packaging container that can be used independently by releasing the combination with the main body portion C (front chamber L). Therefore, when the food (gum) contained in the front chamber L is consumed and the front chamber L is made into an invalid space, the remaining gum can be contained in the rear chamber B by removing the rear chamber B from the front chamber L. In the state, it is carried lightly by about half of the thickness of the original packaging container A. In other words, when one of the plurality of chewing gums is consumed, the packaging container A can be miniaturized (thinned) and reused, and the usability is better.

Here, when the combination of the rear chamber B and the main body portion C is released, it is conceivable, for example, to extract the rear chamber B from the main body portion C by the locking of the stopper portion 17 or the locking piece 30, or by making the body One of the parts C is broken and the back chamber B is taken out. Also, for this purpose, it can also be formed The punching line for cutting the body portion C or the like cuts the processing line.

Further, the chamber B can be closed using the lid 4 after the article state of the combination with the body portion C has been released. That is, the bending in the first folding guide wire 12 of the cover 4 is canceled. That is, the bending between the second sheet 15 which is the front portion of the first lid portion 10 (the portion which is the upper wall of the packaging container A) and the second lid portion 11 which is the lid of the packaging container A is canceled. Thereby, the first lid portion 10 and the second lid portion 11 are flush with each other.

Then, the second folding guide line 13 is a crease (along the second folding guide line 13), and the second sheet 15 and the second lid portion 11 are orthogonal to the first sheet 14 so as to face the front lower side. Flexed. Thereby, the cover 4 is in a state of being closed as shown in FIG. In this state, in the lid 4, the first sheet 14 which is the rear portion of the first lid portion 10 serves as the upper wall of the rear chamber B, and the second sheet 15 and the second lid portion 11 serve as the seals covering the back chamber B. Cover function.

In this way, when the rear chamber B is combined with the front chamber L, the cover of the rear chamber B becomes the cover of the entire packaging container A (see FIG. 12), and when the rear chamber B is separated from the front chamber L and is independent. It becomes the cover of the back chamber B (refer to FIG. 13). Therefore, it is possible to achieve the purpose of not providing the portion that becomes the entire cover of the packaging container A and the portion that becomes the cover of the rear chamber B, and thus the number of parts can be reduced.

Further, in a state in which the lid 4 is closed in the chamber B after the single product state, the first sheet 14 of the first lid portion 10 of the lid 4 covers the upper portion of the rear chamber B, and the second sheet 15 and the second lid portion 11 are covered. The upper part of the front side of the chamber B (the upper side part of the front wall 16 of the rear chamber). Therefore, the take-out port F located at the upper portion of the rear chamber B is closed by the first sheet 14, and the take-out window D located at the upper side portion of the rear chamber front wall 16 is closed by the second sheet 15 and the second lid portion 11. Therefore, when the rear chamber B is used independently, since the lid 4 covers the front side and the upper side of the rear chamber B, it is possible to prevent the food contained in the rear chamber B from being scattered to the front outer side.

Further, by inserting the central portion of the front edge 11A of the second cover portion 11 The slit 9 of the front chamber front wall 16 is brought into engagement with the rear chamber front wall 16 so as not to fall off, maintaining the closed state of the lid 4. Further, when the front end edge 11A of the second lid portion 11 is removed from the slit 9 of the rear chamber front wall 16 and the lid 4 is opened, the food unit 42 can be drawn upward from the take-out port F.

In this manner, the main body portion C is partitioned into the front chamber L and the rear chamber B, and the take-up window G is formed in the front wall 20 of the packaging container in the front chamber L, and the rear chamber B is movable upward relative to the front chamber L. Thereby, it is easy to arrange the foodstuffs accommodated in the inside of the main body part C, and it is easy to take out the foodstuff unit 42 from the front chamber L and the back chamber B.

Further, the rear chamber B can be formed into a separately usable packaging container by releasing the combination with the front chamber L. In this case, for example, when the front chamber L becomes empty, the front chamber L can be discarded and only the rear chamber B can be utilized.

The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the scope of the invention.

For example, in the first embodiment, the following modifications are considered. For example, in the packaging container A, the food unit 42 is accommodated in the entire front and rear rows by the food container unit 42 in each of the front chamber L and the rear chamber B (see FIG. 2). Instead of this, a plurality of rear chambers B may be provided, and the food unit 42 may be accommodated three or more times before. In this case, the food unit 42 of each of the rear chambers B can be easily pinched by drawing a plurality of the rear chambers B in a stepwise manner. Moreover, the number of food units 42 accommodated in each of the front chamber L and the rear chamber B can be appropriately changed.

Further, as a method of closing the lid 4, not only the method of inserting the front edge 11A of the second lid portion 11 into the slits 9, 21 but also the center of the second lid portion 11 or the position close to the front end edge 11A may be used. A method of engaging the slit with the slits 9, 21 by cutting the mountain shape. Further, the shape of the slits 9, 21 is not limited to the one shown in FIG. 4 or FIG. The U shape may be a substantially U shape or a substantially V shape which is upside down, a substantially M shape, a linear shape extending in the lateral direction, or the like.

Further, as a method of combining the rear chamber B and the main body portion C (front chamber L) (manufacturing method of the packaging container A), the left extension plate 25 and the right extension plate 26 may not be followed in the main body portion C. In the state, the rear chamber B is housed in the rear space J to be combined with the main body portion C, and thereafter, the left extension plate 25 and the right extension plate 26 are joined to complete the packaging container A (see FIG. 1).

Moreover, the double-sided backing sheet is used in the case of the cover 4, but it is not limited to this as an attachment means. For example, an adhesive such as a hot melt or a water-soluble adhesive may be applied to at least one of the opposing faces.

Further, the food to be contained in the packaging container A is not particularly limited, but is preferably a plate-shaped elongated food package which is individually packaged as described above. As such a plate-shaped elongated food, in addition to chewing gum, chocolate or candy can also be used.

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 rear wall 32 of the packaging container of the body portion C. However, at this time, it is necessary to separately provide a handle portion to easily pull the rear chamber B upward or press it downward. Further, although not shown, the tamper-proof function may be provided in a packaging container that can be used alone (specifically, the chamber B after the individual state).

Further, the modifications of the first embodiment can be applied to the second to fourth embodiments described below.

In the second embodiment, the first embodiment is different from the first embodiment, and the other aspects are configured in the same manner. Hereinafter, the description will be focused on different aspects. In the following, the same components as those of the first embodiment are denoted by the same reference numerals and signs, and their descriptions are omitted.

Fig. 14 is a development view of the subsequent chamber B2 in the packaging container A2 according to the second embodiment of the present invention. Fig. 15 is a developed view of the body portion C2 in the packaging container A2. Fig. 16 is an exploded perspective view for explaining a state in which the rear chamber B2 is combined with the main body portion C2.

The packaging container A2 includes a body portion C2 and a rear chamber B2. The packaging container A2 is a vertical box shape which is flat in the front-rear direction, and a pair of right and left corners extending in the front surface are formed in an arc shape. In addition, in FIG. 16, FIG. 16 shows the case where four food units 42 are accommodated in the front and rear two rows in the packaging container A2.

The rear chamber B2 is formed by assembling the paper type X2 shown in Fig. 14. The rear chamber wall 1 after the rear chamber B2 is formed into a longitudinal rectangular shape. Further, the angles of the left and right sides of the second sheet 15 of the first lid portion 10 are formed in an arc shape. As a result, the dimension of the second cover portion 11 in the lateral direction is smaller than the dimension of the first sheet 14 of the first cover portion 10 in the lateral direction.

The main body portion C2 is formed by assembling the paper type Y2 shown in Fig. 15 . The packaging container front wall 20, the packaging container rear wall 32, and the front chamber rear wall 27 of the main body portion C2 are formed in a longitudinal rectangular shape.

The front wall 20 of the packaging container and the left side wall 22 of the packaging container are connected via a connecting surface 71. The connecting surface 71 is composed of a plurality of short strip-shaped plates, and is assembled such that the plates are bent and connected to each other on the long sides thereof. Thereby, in the assembled state, the joint surface 71 forms a substantially curved surface. Further, the packaging container front wall 20 and the packaging container right side wall 23 are connected via the same connecting surface 72 as the connecting surface 71.

Further, the conventional tamper-proof method of packaging the entire packaging container from the outside by a transparent film such as polypropylene is not suitable for the manufacturing suitability of the packaging container having a substantially curved surface like the packaging container A2. However, as in the present invention, by making the paper packaging container body tamper-proof, it is not necessary to package the entire packaging container from the outside by a transparent film as is conventional. Therefore, it can be roughly curved like the packaging container A2. The curved packaging container serves as a packaging container for the tamper-proof product.

Further, in the assembled state, with respect to the left-right direction of the packaging container A2, the size of the front wall 20 of the packaging container of the main body portion C2 is narrower than the width of the front wall 16 of the rear chamber.

The configuration for making the corner portions of the left and right side edges of the front surface of the packaging container A2 curved may be applied to the first embodiment and the following embodiments.

Fig. 17 is a development view of the subsequent chamber B3 in the packaging container A3 according to the third embodiment of the present invention. Fig. 18 is a developed view of the body portion 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 portion C3. Fig. 20 (a) is a right side sectional view showing a state in which the lid 4 is opened in the packaging container A3 and the rear chamber B3 is in the lower position, and Fig. 20 (b) is in a state in which the lid 4 is opened and the rear chamber B3 is in the upper position. Right side profile view. Fig. 21 is a perspective view showing a main portion of the packaging container A3 in a state where the lid 82 of the garbage chamber 81 is opened. Fig. 22 (a) is a right side sectional view showing a main portion of the packaging container A3 in a state where the lid 82 of the garbage chamber 81 is opened, and Fig. 22 (b) is a main portion of the packaging container A3 in a state where the lid 82 of the garbage chamber 81 is closed. Right-view view.

First, referring to Fig. 19, the packaging container A3 has a body portion C3 and a rear chamber B3. The packaging container A3 has a box shape that is flat in the longitudinal direction in the front-rear direction, but does not form the curvature of the left and right corner portions of the surface before the second embodiment. Further, a garbage chamber 81 is provided below the storage space H below the packaging container A3. The garbage compartment 81 can be opened and closed by the cover 82.

When the cover 82 is closed, the pair of hooking pieces 91, 92 become non-contact with the left lower extending plate 86 and the lower right extending plate 87, and do not abut against the front chamber bottom wall 24.

In a state in which the lid 82 is opened, the garbage chamber 81 communicates with the outside through a space between the pair of insertion pieces 89, 90 and the left lower extension plate 86 and the lower right extension plate 87.

The configuration of the garbage compartment 81 of the packaging container A3 can also be applied to the first and second embodiments and the following embodiments.

Fig. 23 is a perspective view showing a packaging container A4 according to a fourth embodiment of the present invention, showing a state in which the front cover 4 is opened. Fig. 24 is a perspective view of the packaging container A4, showing a state in which the lid 4 is closed and sealed. Figure 25 is a perspective view of the packaging container A4 showing the state in which the lid 4 is opened after sealing.

The packaging container A4 has a body portion C4 and a rear chamber B. The main body portion C4 is such that the main body portion C is formed with a take-out window G in a paper type (not shown). The packaging container front wall 20 of the main body portion C4 has a U shape in the same shape as the main body portion 60 (see FIG. 2).

That is, the front surface of the upper portion of the front wall 20 of the packaging container of the main body portion C4 is formed with a take-out window G as an opening portion which is opened when the lid 4 is opened. As shown in Fig. 23, the take-up window G is covered by the film 95 before opening.

The diaphragm 95 includes a thin film made of a synthetic resin. Further, in order to ensure the required portion around the take-up window G in the front wall 20 of the packaging container, the film 95 is formed larger than the take-up window G. Also, the diaphragm 95 may be formed to be the same size as the inner surface of the cover 4 or It is larger than this, but it is preferably formed smaller than the cover 4 in order not to be exposed from the cover 4.

Referring to Figures 23 and 24, in the sealed state, the diaphragm 95 and the front surface of the upper portion of the front wall 20 of the packaging container are followed by an adhesive 96 interposed therebetween. Further, the inner surface of the diaphragm 95 and the lid 4 is followed by the adhesive 97 interposed therebetween. The subsequent agent 96 and the adhesive 97 are specifically composed of the above-described double-sided back sheet. Further, as the adhesives 96 and 97, a hot melt or a water-soluble adhesive or the like can also be used. For example, the adhesion of the adhesive 97 following the film 95 to the inner face of the cover 4 is set to be stronger than the adhesion of the adhesive 96 following the film 95 to the front surface of the front wall 20 of the packaging container.

Thereby, if the lid 4 is opened and the lid is opened, as shown in FIG. 25, the membrane sheet 95 and the lid 4 are unloaded from the front surface of the upper portion of the front wall 20 of the packaging container (specifically, the peripheral portion of the take-up window G). In addition, the take-out window G appears.

Further, the adhesive force of the adhesives 96 and 97 is set so as to be remarkably lowered if peeled off afterwards. The peeled film 95 at the time of opening cannot be reattached to the front wall 20 of the packaging container.

As described above, the paper packaging container A4 having the tamper-proof function can be realized by covering the film 95 of the take-out window G and the adhesives 96 and 97. For example, if the cover 4 is unsealed, the diaphragm 95 is peeled off from the front wall 20 of the packaging container, and the take-up window G appears, so that even if the cover 4 is closed thereafter, it is easily judged to be opened.

Further, it is preferable that the take-out window G and the film sheet 95 covering the cover window are provided so as to be hidden by the cover 4 in a state where the cover 4 is closed and overlapped with the front wall 20 of the packaging container. In this case, the appearance of the packaging container A4 in a state in which the lid 4 is closed can be made good.

Further, the film 95 may be a metal foil such as a thin paper or an aluminum foil. Further, the adhesive force of the adhesive 96 may be designed to be strong, and when the cover 4 is opened and opened, one of the diaphragms 95 is partially broken to maintain the shape of the front wall 20 of the packaging container. State residual.

Further, the configuration of the tamper-proof function of the packaging container A4 can be applied to each of the above embodiments.
