The outlet K is continuous with the outlet window G when the outlet window G is formed on the packaging container front wall 20 (see FIG. 2).

The lower end of the front space I is blocked by the front chamber bottom wall 24 in the front space I substantially in the front half of the accommodation space H, . The upper portion of the front space I is opened forward from the take-out window G when the take-out window G is formed (see FIG. 2).

Here, the packaging container front wall 20, the front chamber rear wall 27, the front chamber bottom wall 24, and the packaging container left wall 22 partitioning the front space I in the accommodation space H, And the end of the approximately forward half of each of the packaging container right side walls 23 constitute the front chamber L. [ The front chamber L may include approximately 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 whole becomes the front chamber L.

In the rear space J of the substantially rear half of the accommodation space H, the lower end of the rear space J is divided by the lower end edges of the front chamber rear wall 27 and the packaging container rear wall 32, (See FIG. 8 (e), which will be described later), and the upper end thereof is open to the upper side as a substantially rear half of the air outlet K. That is, the rear space J is a space between the front chamber rear wall 27 and the packaging container rear wall 32, which is opened upside down.

8 shows a side view of the main body portion C. As shown in Fig.

Fig. 9 is an exploded perspective view for explaining a state in which the rear chamber B is assembled to the main body C. 10A is a perspective view of the packaging container A and shows a state in which the cover 4 before being opened is opened. Fig. 10B is a sectional view of the right side of the packaging container A of Fig. to be.

Referring to Fig. 9, the packaging chamber A is completed by assembling the rear chamber B and the main body C assembled as described below. In the packaging container A, for example, six food units 42 are housed in two front and rear rows.

The food unit 42 is a piece of gum as a small piece of food, which is packaged in a wrapping paper and individually packaged. For example, a plurality of food units 42 are accommodated in the accommodation space E of the rear chamber B in a state in which they are arranged side by side in the lateral direction, and the rear chamber rear wall (Adhesive tape is also acceptable) to the adhesive layer 1. 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 in which they are arranged side by side in the lateral direction, And the front chamber rear wall 27 of the front chamber. Of course, the food unit 42 may be accommodated without adhering to the packaging container A.

First, as shown in Fig. 9, the cover 4 of the rear chamber B is opened. At this time, the cover 4 is continuously formed upward from the upper edge (upper side 1U) of the rear chamber rear wall 1, and is substantially the same plane as the rear chamber rear wall 1. [

In the packaging container A, the cover 4 is formed continuously from the upper edge of the rear chamber rear wall 1. However, the rear chamber rear wall 1 is formed in the rear wall of the packaging container rear wall 1 32, and also functions as a rear wall of the packaging container (A). Therefore, it can be said that the cover 4 is formed continuously 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 cuttable portion 61 of the main body C are directed in the same direction (toward the reader in FIG. 9) B is inserted into the second half portion of the air outlet K of the main body C from above and is moved to the inside of the main body C.

Thus, 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 cover 10 of the cover 4 are the largest in the width direction (the wide width) among the rear chamber B and the main body C, Are brought into contact with the upper edges of the packaging container left side wall 22 and the packaging container right side wall 23 of the main body portion C with respect to the left and right upper edges, respectively. This prevents the rear chamber B from moving downward in the rear space J and prevents the rear chamber B from being pulled out from the bottom side insertion opening M of the main body portion C.

10, immediately after the rear chamber B is inserted into the rear space J of the main body C as described above, the cover 4 is opened and the rear edge of the rear chamber rear wall 1 (The upper side 1U). Here, the cover 4 is folded forward so as to be orthogonal to the rear chamber rear wall 1 with the upper side 1U of the rear chamber rear wall 1 being a folding piece of gold. In the cover 4, The second cover portion 11 is folded downward so as to be perpendicular to the first cover portion 10 with the guide 12 as a folding piece of gold. Therefore, the cover 4 is closed as shown in Fig.

Referring to Fig. 1, in the closed state, the cover 4 constitutes a flap. In the cover 4, the first cover portion 10 covers the upper portion of the packaging container A and the second cover portion 11 covers the front upper portion of the packaging container A (the packaging container front wall 20 ). Therefore, the outlet K of the main body C on the upper portion of the packaging container A is blocked by the first cover portion 10. In other words, the first cover portion 10 constitutes the upper wall of the packaging container A. In this case, since it is not necessary to form flaps on both sides of the front chamber L and the rear chamber B to cover the upper portion and the front upper portion of the packaging container A, the number of parts can be reduced.

The cover 4 thus closed is adhered to the cuttable 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 constituted by a double-sided adhesive sheet existing between the cover 4 and the cuttable portion 61. Such a double-sided adhesive sheet is obtained by applying an adhesive to both sides of a thin resin sheet.

In the sealed state, the main body portion 60 and the cuttable portion 61 are mutually connected, and the cuttable portion 61 and the cover 4 are bonded to each other.

In order to seal the packaging container A, it is preferable to have the leading edge 11A of the cover 4 and pull the cover 4 up.

2, when the cover 4 is lifted, the cuttable portion 61 is pulled into the cover 4, the break along the dashed line 62 occurs, and the cuttable portion 61 61 are cut off from the packaging container front wall 20 and separated. The extraction window G is surrounded by the main body portion 60 of the packaging container front wall 20 and is substantially the same size as the extraction window D of the rear chamber front wall 16 . On the back surface of the cover 4, the cut-off and separated cut-away portions 61 are adhered as they are.

A dotted line 62 as a cutting and separating line is formed and the upper part of the packaging container front wall 20 adhered to the cover 4 is formed as described above with reference to Figs. 1 (a) and 2 (a) Can be detached from the packaging container front wall (20) at the time of unsealing, it is possible to realize a paper made packaging container (A) having an easy operation change preventing function for sealing the cover (4).

Therefore, when the cover 4 is opened at the time of opening, the cut-out portion 61 at the upper portion of the packaging container front wall 20 of the main body C is cut and separated to reveal the take-out window G, Even if the cover 4 is closed, it is easily judged that the opening is completed. That is, when the cover 4 closed after the opening is opened, the cuttable portion 61 of the packaging container front wall 20 is not cut off and separated, so that it can be easily known that the cover 4 is completely opened.

When the cover 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 cover 4 and taken out to the upper part of the packaging container front wall 20 The window (G) is exposed. Since the takeout window G is exposed when the cover 4 is opened, it is easy to take out the food unit 42 housed therein. Since the easy operation change preventing function is provided in the main body of the packaging container (A), 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, .

As the cutting and separating processing line, a dotted line 62 having a short cut portion formed intermittently in the packaging container front wall 20 is preferable. That is, processing of the dotted line 62 is easy, and cutting and separation are also easy.

As the bonding means for bonding the cover 4 and the cuttable portion 61 to each other, a double-sided adhesive sheet is preferably used. Therefore, the adhesive can be easily handled, and the cuttable portion 61 of the packaging container front wall 20 and the cover 4 can be easily bonded to each other.

11A is a perspective view of the packaging container A and shows a state in which the rear chamber B with the cover 4 opened after the sealing is pulled up against the main body C, Is a right side sectional view of the packaging container (A) in Fig. 11 (a). Fig. 12 is a perspective view of the opened packaging container A with the cover 4 closed. Fig. 13 is a perspective view showing a state in which the cover 4 is closed in the rear chamber B in a state in which the rear chamber B is picked up from the packaging container A. Fig. 1, 2, and 9 to 13, the one nearer to the reader on the ground is the front side of the packaging container A, and the one farther away from the reader on the ground is the front side of the packaging container A, It's on the back.

2 and 11, in a state in which the cover 4 is opened, the rear chamber B is moved from the upper position shown in Fig. 11 (b) to the upper position shown in Fig. 2 And can be slid between the lower positions.

The upper edge of the front extension plate 8 on the rear chamber front wall 16 on the side of the rear chamber B at the lower position is located on the rear side of the front chamber B on the side of the main body C as shown in Fig. And is opposed to the stopper 30 (strictly speaking, in the vicinity of the connecting portion of the folded stopper piece 30 and the front chamber rear wall 27) of the wall 27 at a predetermined distance from the lower side.

The upper edge of the front extension forming plate 8 on the side of the rear chamber B located at the upper position is the stopping piece 30 on the side of the front chamber L as shown in Figure 11 (b) (The connecting portion between the piece 30 and the front chamber rear wall 27), the sliding with respect to the upper side of the rear chamber B is limited up to the predetermined amount Z. [

11, the rear chamber B and the front chamber L are stepped, the upper end of the rear chamber B protrudes from the front chamber L, and the rear chamber B is extended from the rear chamber B The food unit 42 can be easily taken out.

To make the upper position, only the rear chamber B (for example, the cover 4) is held and pulled upward. Alternatively, the rear chamber bottom wall 5 exposed from the insertion port M of the main body C may be pressed.

As described above, the rear chamber B is assembled with respect to the front chamber L so as to be slidable upward by a predetermined amount Z relative to the front chamber L. Therefore, it is possible to prevent the gum in the rear row (rear chamber B) from being placed at a position higher than the gum in the front row (front chamber L) by forming a floor-raised portion in front of the packaging container A in advance, , And the rear chamber B is slid upward relative to the front chamber L, gum in the rear row can be disposed at a position higher than the gum in the front row (see FIG. 11). Therefore, since the bottomed portion is not formed, the packaging container A can be downsized.

That is, in such a packaging container (A), it is possible to both ease the picking up of the foods accommodated in the front and back in a plurality of rows, and to downsize the container.

To close the packaging container A, the rear chamber B is placed at the lower position and the rear chamber B (the portion other than the cover 4) is completely contained in the rear space J of the main body portion C, And the takeout window G is covered with the second cover portion 11 of the cover 4 (see Fig. 12). At this time, the left and right stoppers 17 of the first cover portion 10 of the cover 4 are positioned in 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 portion C It is possible to prevent the rear chamber B accommodated in the rear space J from being pulled out from the bottom side insertion opening M of the main body C and falling off.

Further, the take-out window G on the upper portion of the packaging container front wall 20 is blocked by the second cover portion 11. The central part of the leading edge 11A of the second cover part 11 is inserted into the cut part 21 of the packaging container front wall 20 so as to prevent the cover 4 from being detached from the packaging container front wall 20 ). Therefore, the closed state of the cover 4 is maintained.

Only the rear chamber B may be taken out from the main body C as shown in Fig. The rear chamber B releases the assembly with the main body C (the front chamber L), thereby forming a usable packaging container. Therefore, when the front chamber L becomes a dead space by eating the food (gum) contained in the front chamber L, the rear chamber B is separated from the front chamber L, (B), it can be transported in a compact manner to a thickness of about half the size of the original packaging container (A). That is, when some of the gums are consumed, the packaging container A can be downsized (thinned) and reused, which is convenient to use.

In order to release the assembly of the rear chamber B and the main body C, for example, the rear chamber B is fixed to the main body C by resistance against stopping by the stopper 17 or the stopper 30 And the rear chamber B is taken out by breaking a part of the main body C, as shown in Fig. For this reason, a cutting / separating line such as a dotted line for breaking the main body C may be formed.

It is also possible to close the rear chamber B in a single product state in which the assembly with the main body C is released by using the cover 4. [ That is, the folding of the first folding guide 12 of the cover 4 is eliminated. That is, the bending between the second piece 15, which is the front portion of the first cover portion 10, which was the upper wall of the packaging container A, and the second cover portion 11, which is the flap of the packaging container A, Remove. Therefore, the first cover portion 10 and the second cover portion 11 become one surface.

Next, the second folding guide 13 is made of gold (along the second folding guide 13), and the second piece 15 and the second cover portion 11 are folded into the first piece 14 So as to be orthogonal to each other. Therefore, the cover 4 is closed as shown in Fig. In this state, in the cover 4, the first piece 14, which is the rear part of the first cover part 10, becomes the upper side wall of the rear chamber B and the second piece 15 and the second cover part 11 function as a flap covering the front of the rear chamber B. [

The cover 4 of the rear chamber B thus becomes the flap of the entire packaging container A when the rear chamber B is assembled in the front chamber L When the chamber B is separated from the front chamber L and is independent, it becomes a flap of the rear chamber B (see Fig. 13). Therefore, it is not necessary to separately form the flap portion of the entire packaging container A and the flap portion of the rear chamber B, so that the number of parts can be reduced.

The first piece 14 of the first cover portion 10 of the cover 4 covers the upper portion of the rear chamber B when the cover 4 is closed in the rear chamber B in the single product state, The second piece 15 and the second cover portion 11 cover the front upper portion of the rear chamber B (the upper portion of the rear chamber front wall 16). The outlet window F at the upper portion of the rear chamber B is blocked by the first piece 14 and the outlet window D at the upper portion of the rear chamber front wall 16 is closed by the second piece 14. [ (15) and the second cover portion (11). Therefore, when the rear chamber B is used independently, the cover 4 covers the front and the upper side of the rear chamber B, so that it is possible to prevent the food stored in the rear chamber B from being poured downward forward .

The central part of the leading edge 11A of the second cover part 11 is inserted into the cut part 9 of the rear chamber front wall 16 so that the rear chamber front wall 16, and the closed state of the cover 4 is maintained. When the front edge 11A of the second cover portion 11 is separated from the cut portion 9 of the rear chamber front wall 16 and the cover 4 is opened, It is possible to pull it upward.

The main body C is partitioned into a front chamber L and a rear chamber B and a takeout window G is formed on the packaging container front wall 20 of the front chamber L, The chamber (B) is movable upward relative to the front chamber (L). Therefore, the food contained in the main body C can easily be aligned, and the food unit 42 can be easily picked up from the front chamber L and the rear chamber B.

In addition, the rear chamber B is capable of forming a usable packaging container by releasing its assembly 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 used.

The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims.

For example, in the first embodiment, the following modifications are conceivable. For example, in the packaging container A, the food unit 42 is accommodated in the front and rear chambers B and L as a whole by accommodating the food unit 42 in each of the front chamber L and the rear chamber B Reference). Alternatively, a plurality of rear chambers B may be formed to accommodate the food units 42 in three or more rows before and after. In this case, the food units 42 of the respective rear chambers B can be easily picked up by pulling out the plurality of rear chambers B in a stepwise manner. The number of food units 42 accommodated in each of the front chamber L and the rear chamber B can be appropriately changed.

As a method of closing the cover 4, not only the method of inserting the leading edge 11A of the second cover portion 11 into the cut portions 9 and 21 but also the method of inserting the leading end edge 11A of the second cover portion 11 into the center of the second cover portion 11 A method may be used in which a "crest" cut portion is inserted into a portion near the leading edge 11A and the cut portion and the cut portions 9, 21 are joined. The cut portions 9 and 21 are not limited to the substantially U-shaped portions shown in Figs. 4 and 7, and may be substantially U-shaped, inverted V-shaped, approximately M-shaped, A straight line extending in the transverse direction, or the like.

A method of assembling the packaging chamber A between the rear chamber B and the main body C and the front chamber L is the same as that in the main body C except that the left extension plate 25 and the right side The rear chamber B is housed in the rear space J and assembled to the main body C in a state in which the extension forming plate 26 is not adhered, The plate 26 may be adhered to complete the packaging container A (see Fig. 1).

Although the double-sided adhesive sheet is used for adhering the cover 4, the adhesive means is not limited thereto. For example, an adhesive such as hot melt or water-soluble adhesive may be applied to at least one side of the mutually facing adhesive surfaces.

The food to be contained in the packaging container (A) is not particularly limited, but it is preferable that the above-mentioned individually wrapped plate-shaped food having a long length is used. As food having such a long plate shape, chocolate or candy may be used in addition to gum.

In the packaging container A, the cover 4 is formed continuously from the upper edge of the rear chamber rear wall 1, but is formed continuously from the upper edge of the packaging container rear wall 32 of the body portion C . At that time, however, it is necessary to separately form the handle portion in order to pull the rear chamber B upward or to push it downward easily. Although not shown in the drawings, the packaging changeable container (specifically, the rear chamber B in a stand-alone state) which can be used alone may be provided with the above-described easy operation change prevention function.

The modification of the first embodiment can also be applied to the second to fourth embodiments to be described below.

The second embodiment is different from the first embodiment in the following points, and the remaining points are the same. Hereinafter, different points will be mainly described. Regarding constituent elements of the following embodiments, the constituent elements having the same functions as those of the first embodiment are denoted by the same reference numerals and signs as those of the constituent elements of the first embodiment, and a description thereof will be omitted.

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

The packaging container A2 has a main body C2 and a rear chamber B2. The packaging container A2 is in the form of a vertically long box flat in the front-rear direction, and a pair of right and left horns extending vertically on the front face are rounded. 16 shows a case in which four food units 42 are housed in two front and rear rows in the packaging container A2.

The rear chamber B2 is formed by assembling the mold X2 shown in Fig. The rear chamber rear wall 1 of the rear chamber B2 is formed into a rectangular shape having a long length. The horns on the right and left sides of the second piece 15 of the first cover portion 10 are formed in a round shape. The length of the second cover portion 11 in the transverse direction is narrower than the length of the first piece 14 of the first cover portion 10 in the transverse direction.

The body portion C2 is formed by assembling the mold Y2 shown in Fig. The packaging container front wall 20, the packaging container rear wall 32 and the front chamber rear wall 27 of the main body C2 are formed into a rectangular shape having a long length.

The packaging container front wall 20 and the packaging container left side wall 22 are connected to each other through a connection surface 71. The connecting surface 71 is constituted by a plurality of short book-shaped plates, and these plates are assembled so that they are folded and connected to each other on their long sides. Therefore, in the assembled state, the connecting surface 71 forms a substantially curved surface. The packaging container front wall 20 and the packaging container right side wall 23 are connected to each other via a connection surface 72 having the same shape as the connection surface 71.

The conventional easy manipulation change prevention method such as packaging the entire packaging container from the outside with a transparent film such as polypropylene is preferable for packaging containers having substantially curved surfaces such as packaging container A2 I do not. However, 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 by holding the easy-operation alteration prevention function on the paper packaging container main body. Therefore, a packaging container having a substantially curved surface, such as the packaging container A2, can be employed as a packaging container for a product having an easy operation change prevention function.

The length of the packaging container front wall 20 of the main body C2 is narrower than the width of the rear chamber front wall 16 in the left and right direction of the packaging container A2 in the assembled state.

The configuration for making the conical 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 each embodiment described later.

19, the packaging container A3 has a main body C3 and a rear chamber B3. The packaging container A3 is in the shape of a longitudinal long box flat in the front-rear direction, but the rounded portion of the right and left conical portions on the front surface as in the second embodiment is not formed. A dust chamber 81 is formed in the lower portion of the packaging container A3, that is, the lower side of the accommodation space H. The dust chamber 81 can be opened and closed by the cover 82. [ For example, the dust chamber 81 can accommodate unused items such as used packaging materials separated from food, chewed gum, and the like, which is convenient. The dust chamber 81 is not limited to an unused object, but may be used as an accommodating chamber capable of accommodating other articles.

19 shows a case in which four food units 42 are housed in two rows in front and rear in the packaging container A3.

Referring to Fig. 17, the rear chamber B3 is formed by assembling the mold X3. The rear chamber rear wall 1 is formed into a rectangular shape having a long length. The rear chamber rear wall 1 is formed with an inverted U-shaped cut portion 83a for forming a stopping piece 83 of a shape to be cut and formed. The portion surrounded by the cut portion 83a is folded back, so that the stopper 83 is formed. Further, the front edge 11A of the second cover portion 11 extends straightly to the left and right. The cut portion 9 of the front extension plate 8 of the rear chamber B3 is formed in a substantially M-shape.

Referring to Fig. 18, the main body C3 is formed by assembling the mold Y3. The packaging container rear wall 32 (left extension plate 25, right extension plate 26) and the front chamber rear wall 27 of the body C3 are formed in a rectangular shape having a long length.

The body portion C3 in the state of Y3 has a substantially U-shaped packaging container front wall 20 having a long length. In the assembled state, a take-out window G (see Fig. 18) is formed in the upper part of the packaging container front wall 20. [ The take-out window G is formed in the same size as the take-out window D of the rear chamber front wall 16 (see Fig. 17). The cut portion 21 of the packaging container front wall 20 is formed in a substantially M-shape.

The shape of the cut portions 9 and 21 is not limited to the substantially M shape but may be a substantially M shape having an upside down shape, a substantially V shape, a substantially U shape, a straight shape extending in the transverse direction, etc. .

A rectangular notch 84 is formed in the packaging container right extension plate 26. 20, the notch 84 and the stopper piece 83 (see Fig. 17) formed in the rear chamber rear wall 1 are opposed to each other in the up-and-down direction in the state in which the packaging container A3 is assembled And are arranged to be mutually engageable.

20 (b), when the rear chamber B3 is in the upper position, the lower edge portion of the notch 84 and the stopper 83 are vertically spaced apart from each other. 20 (a), the lower edge of the notch 84 engages with the lower edge of the stopper 83 when the rear chamber B3 is in the lower position. Specifically, the notch 84 receives the stopper 83, and the lower edge of the notch 84 comes into contact with the lower edge of the stopper 83, receives it, and stops. Therefore, the slidable lower position of the rear chamber B3 is restricted, and the rear chamber B3 is prevented from being caught in the dust chamber 81. [

Since the lower edge of the notch 84 and the lower edge of the stopper 83 engage with each other and the sliding of the rear chamber B3 against the lower side is restricted, the left and right stoppers 17 of the first cover portion 10 , It may not necessarily be formed.

18 and 20A, the front chamber bottom wall 24 in the main body portion C3 in the developed view is formed with the folded portion 85 at the lower side 20D of the packaging container front wall 20, Respectively. 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 (indicated by a rectangle of one dotted line in Fig. 18) on at least one side of the folded portion 85 and the back surface of the packaging container front wall 20, and both regions are shown in Fig. ). The front chamber bottom wall 24 is disposed apart from the lower side 20D of the packaging container front wall 20 by the height of the folded portion 85 in the assembled state by being disposed through the folded- , And a dust chamber 81 is defined on the lower side of the front chamber bottom wall 24.

18 and 19, most of the packaging container front wall 20 forms the front wall of the front chamber L, and the remaining portion of the packaging container front wall 20 below this front wall So that the front wall of the dust chamber 81 is formed. The remaining part of the packaging container left side wall 22 on the lower side of the left side wall is located on the left side of the dust chamber 81 It forms a wall. On the left side wall, a left lower extension forming plate 86 is formed. Most of the packaging container right side wall 23 forms the right side wall of the front chamber L and the remaining portion of the packaging container right side wall 23 on the lower side of this right side wall is located on the right side of the dust chamber 81 It forms a wall. On the right side wall, a right lower extension forming plate 87 is formed. The left lower extension forming plate 86 and the lower right extension forming plate 87 are folded toward the inside of the main body C3 in the assembled main body C3 and the dust chamber 81 The size of the opening of the opening portion is suppressed to be small.

A pair of catching pieces 89 and 90 and a pair of catching pieces 91 and 92 are formed in succession on the left side extension plate 25 of the main body C3. do. The packaging container lower side wall 88 and the pair of insertion pieces 89 and 90 constitute a cover 82 that can be opened and closed.

21 and 22, in the assembled state of the main body C3, the plug-in piece 89 on one side is connected to the left lower extension forming plate 86 and the packaging container front wall 20, Folded portion 85). The plugging piece 90 on the other side is inserted into the gap between the right lower extension forming plate 87 and the packaging container front wall 20 (folded-in portion 85). When the cover 82 is opened, the pair of hooking pieces 91 and 92 come into contact with the left lower extension forming plate 86 and the right lower extension forming plate 87, Is regulated. When the cover 82 is closed, the pair of hooking pieces 91 and 92 are brought into contact with the left lower extension forming plate 86 and the right lower extension forming plate 87, (Not shown).

When the cover 82 is opened, the dust chamber 81 is inserted between the pair of insertion pieces 89, 90 and between the left lower extension forming plate 86 and the right lower extension forming plate 87, And is communicated to the outside.

The configuration of the dust chamber 81 of the packaging container A3 may be applied to the embodiments to be described later together with the first and second embodiments.

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

The packaging container A4 has a main body C4 and a rear chamber B. The main body C4 is formed on the main body C in the above-described mold (not shown) with the take-out window G. 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 portion 60 (see Fig. 2) described above.

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

The film sheet 95 is made of a thin film made of a synthetic resin. The film sheet 95 is formed so as to be larger than the take-out window G so as to secure an adhesive area required around the take-out window G in the packaging container front wall 20. [ The film sheet 95 may be formed to have the same size as the back surface of the cover 4 or larger than the back surface of the cover 4 but is preferably formed smaller than the cover 4 so as not to protrude from the cover 4.

23 and 24, in the sealed state, the film sheet 95 and the upper surface of the packaging container front wall 20 are adhered by the adhesive 96 existing therebetween. The film sheet 95 and the back surface of the cover 4 are adhered by the adhesive 97 existing therebetween. Specifically, the adhesive 96 and the adhesive 97 are composed of the double-sided adhesive sheet described above. As the adhesives 96 and 97, a hot melt adhesive, a water-soluble adhesive, or the like may be used. The adhesive force of the adhesive 97 for bonding the film sheet 95 to the back surface of the cover 4 is greater than the adhesive strength of the adhesive 96 for bonding the film sheet 95 to the front surface of the packaging container front wall 20. [ It is set stronger than the adhesive force.

25, when the cover 4 is opened and opened, the film sheet 95 together with the cover 4 covers the upper front surface of the packaging container front wall 20 (specifically, around the take-out window G) Portion), and the take-out window G is exposed.

Further, the adhesive force of the adhesives 96, 97 is set so as to be significantly lowered when peeled off after bonding. The film sheet 95 peeled off at the time of opening can not be adhered to the packaging container front wall 20 again.

As described above, the paper bag 95 and the adhesives 96, 97 covering the take-out window G can realize a paper-made packaging container A4 having an easy operation change preventing function. For example, when the cover 4 is opened, the film sheet 95 is peeled off from the packaging container front wall 20 and the take-out window G is exposed. Thereafter, even if the cover 4 is closed, Can be easily known.

It is preferable that the take-out window G and the film sheet 95 covering the take-out window G are formed so as to be blocked by the cover 4 when the cover 4 is closed and overlapped with the packaging container front wall 20 . In this case, the appearance of the packaging container A4 with the cover 4 closed can be improved.

The film sheet 95 may be made of a metal foil such as a thin paper or aluminum foil. When the cover 4 is opened and opened, a part of the film sheet 95 may be torn to remain adhered to the packaging container front wall 20 by designing the adhesive 6 to have a strong adhesive force.

The configuration relating to the easy operation change preventing function of the packaging container A4 may be applied to each of the above-described embodiments.

It is possible to carry out various design changes within the scope of the matters described in the claims.
