Description

Technical Field

[0001] This invention relates to a package for packaging and transporting the contents of products in tube containers, etc., and displaying them as they are on the store shelf.

Background Art

[0002] Conventionally, for example, there is a package for accommodating a product in a tube container and displaying it as it is on the store shelf. For example, the packaging container disclosed in Patent Document 1 includes a packaging body main body made of a sheet-like member for accommodating a tube container filled with contents, a bottom portion, and a cylindrical body portion extending upward from this bottom portion and covering at least the lower circumferential surface of the container and configured to be substantially the same shape along the lower circumferential surface. It has an extension portion extending upward from a specific location at the upper end of the body portion, and an abutting portion for abutting against at least a part of the upper end of the container accommodated in the packaging main body to prevent the container from moving upward. A notch for exposing the upper portion of a specific range extending from the front surface to the rear surface among the outer surfaces of the container accommodated in the packaging main body is formed by the upper end of the body portion and the lateral surface of the extension portion. Thereby, the product can be accommodated without rattling with a simple configuration, and moreover, the product can be efficiently shown.

[0003] Also, the display package for a product in a tube disclosed in Patent Document 2 uses a single sheet material, connects a pair of frame plates via a fold line, and connects leg pieces to the lower ends of each frame plate via a fold line. Each frame plate forms a window corresponding to the vertical shape of the tube from the lower end upward. On both lateral sides of the lower part of the window, there are semi-annular holding pieces that can be raised with a horizontal fold line as a hinge. A clamping piece is formed facing the upper end of the window, and a hanging hole is drilled above it. When using this display package, the frame plates are overlapped and fixed together, the tube is fitted into the window, the pair of holding pieces are raised in opposite directions, the outer periphery of the head side of the tube is surrounded by the pair of annular holding pieces, the tail of the tube is sandwiched between the pair of clamping pieces, and the head end face of the tube is abutted against the lower edge of the window. Thereby, it is possible to select between a hanging display state and a standing display state at the store. In the hanging display state, the fall of the tube is surely prevented, and in the standing display state, it is difficult to fall over. [Prior art documents] [Patent Documents]

[Figure 6] This is an unfolded view of the packaging according to the second embodiment of this invention. [Modes for carrying out the invention]

[0014] The embodiments of this invention will now be described based on the drawings. Figures 1 to 4 show the first embodiment of this invention, in which the packaging body 10 is made by assembling packaging body forming pieces 12 formed by punching out a blank sheet of paper. Figure 2 is an unfolded view of the packaging body forming piece 12 as seen from the surface, and is provided with a long rectangular front 14, and on one of the pair of side edges of the front 14 along the longitudinal direction, is provided a rectangular back 16 which is shorter in the longitudinal direction than the front 14, separated by a fold line 18. On the side edge of the front 14 opposite to the fold line 18, is provided a glued piece 20 which is glued to the back surface of the back 16 when the packaging body 10 is assembled, separated by a fold line 22.

[0015] On the front surface 14, one of a pair of ends located approximately perpendicular to the fold line 18 is the upper end 14a, which is located above when in use, and the other end is the lower end 14b. Near the upper end 14a of the front surface 14, a circular break line 24 is provided that forms a hole into which a hanging device such as a hanging rod is inserted when the product is displayed in a store. At the corner enclosed by the fold line 22 and the lower end 14b, an arc-shaped fold line 26 is provided that continues from the middle of the fold line 22 to the middle of the lower end 14b. One end of the fold line 26 continues to the fold line 22 at a position slightly closer to the lower end 14b than to the upper end 14a, and the other end continues to the fold line 22 at a position slightly closer to the fold line 22 from the middle of the lower end 14b, and the area near the middle of the fold line 26 is an arc shape that bulges towards the center of the front surface 14. A fold line 28, symmetrical to the fold line 26, is also provided at the corner enclosed by the fold line 18 and the lower end 14b. One end of the fold line 28 continues to the fold line 18 at a position slightly closer to the lower end 14b than to the upper end 14a, and the other end continues to the fold line 18 at a position slightly closer to the fold line 18 from the middle of the lower end 14b. The area near the middle of the fold line 28 is an arc shape that bulges towards the center of the front surface 14.

[0016] At the lower end 14b of the front surface 14, a substantially rectangular bottom portion 30 is provided between the folding line 26 and the folding line 28, separated by a scoring line 32. The length of the bottom portion 30 from the scoring line 32 to the end portion 30a opposite to the scoring line 32 is, in the assembled state of the package 10, the length from the scoring line 32 to approximately the center of the lower rectangle of the substantially hexagonal opening when the front surface 14 and the back surface 16 form a cylindrical body. The end portion 30a opposite to the scoring line 32 is parallel to the scoring line 32 and has approximately the same length as the scoring line 32. A pair of side edge portions 30b intersecting the end portion 30a, about half of which is continuous with the end portion 30a, is a straight line substantially perpendicular to the end portion 30a, and about half of which is continuous with the scoring line 32 is a straight line inclined towards the end of the scoring line 32, continuously forming an obtuse angle with the scoring line 32. At the end portion 30a of the bottom portion 30, a rectangular pasting piece 34 smaller than the bottom portion 30 is provided via a scoring line 36.

[0017] The scoring line 32 is provided at a position slightly closer to the center of the front surface 14 than the lower ends of the scoring lines 18 and 22. The lower end 14b located between the lower ends of the scoring lines 18 and 22 and the end of the scoring line 32 has a corner portion that is bent at an obtuse angle of a predetermined angle near the end of the scoring line 32 and protrudes downward, forming an inverted Z - shape. The apex of this corner portion becomes the leg portion 15 when the package 10 is placed on a placement surface such as a shelf for display in the used state. The leg portions 15 are provided one on each side of the scoring line 32, and the pair of leg portions 15 are symmetrical to each other.

[0018] A trapezoidal folded-over piece 38 is provided at the upper end 14a of the front surface 14, separated by a crease line 40. The folded-over piece 38 has a lower base shorter than the upper end 14a, meaning the crease line 40 is shorter than the upper end 14a. The tip 38a of the folded-over piece 38 opposite the crease line 40 has an upper base shorter than the lower base. The four corners of the folded-over piece 38 are rounded and chamfered. Near the crease line 40 of the folded-over piece 38, a through-hole 42 is provided for insertion into a suspension device such as a hanging rod. The through-hole 42 approximately coincides with the break line 24 when the folded-over piece 38 is folded back to the front surface 14 along the crease line 40 in the assembled state of the packaging body 10. A fold line 44, approximately parallel to the crease line 40, is provided at a position slightly further forward 38a than the through-hole 42. The fold line 44 is continuous at both ends with a pair of side edges 38b that intersect the tip 38a of the folded piece 38, and in the middle portion, a semicircular cutting line 46 is provided that bulges out from the fold line 44 toward the tip 38a. The portion of the cutting line 46 that is continuous with the fold line 44 forms a small semicircular shape that bulges slightly toward the fold line 40 before continuing with the fold line 44. The fold line 44 is not provided inside the cutting line 46 and is interrupted, and the inside of the cutting line 46 becomes a tongue piece 48 that locks the contents 78, such as a tube container, in a sealed state.

[0019] A pair of break lines 50 for opening are provided between the cutting line 46 and the side edge 38b. The break lines 50 are straight lines, one end of which continues from the middle of the semicircular cutting line 46 to a position slightly closer to the fold line 44, and the other end of which continues from the side edge 38b to a position slightly closer to the tip 38a than the fold line 44, and the straight line that approaches the side edge 38b becomes closer to the tip 38a. The pair of break lines 50 are provided on the left and right sides of the folded piece 38, with the middle in between, at the same angle, forming a V shape.

[0020] The tip 38a of the return piece 38 is a straight line parallel to the fold line 40. In the middle of the tip 38a, a locking piece 52, which is an arrow-shaped protruding piece, is provided so as to protrude laterally, being separated by the fold line 54. The portions of the locking piece 52 that project outwards on both sides in the direction parallel to the fold line 54 become protruding portions 52a that are inserted into and locked by a cutting line 62 described later. At the center of the locking piece 52, a folding line 56 is provided at a substantially right angle to the fold line 54. One end of the folding line 56 is continuous with the pointed tip of the locking piece 52, and the other end is continuous with the middle of the fold line 54. In the middle of the fold line 54, a short cutting line 58 is provided, and the cutting line 58 is an arc-shaped that bulges towards the center of the locking piece 52. The folding line 56 is continuous with the cutting line 58.

[0021] On the back surface 16, one of a pair of end portions that is positioned at a substantially right angle to the fold line 18 is an upper end portion 16a that is positioned upwards in the use state, and the opposite side is a lower end portion 16b. The upper end portion 16a is at a position slightly shifted downward from the upper end portion 14a of the front surface 14 towards the lower end portion 14b, and the middle portion of the upper end portion 16a is an arc-shaped that sinks towards the center of the back surface 16. The lower end portion 16b is continuous with the lower end portion 14b.

[0022] Near the upper end portion 16a of the back surface 16, a locking hole 60 into which the locking piece 52 is inserted and locked in the use state is provided. The locking hole 60 is a rectangle that is long in a direction intersecting the fold line 18. On the left and right of the edge portion away from the upper end portion 16a, cutting lines 62 formed on the extension of the straight edge portion extend outwards on both sides, and the cutting lines 62 are bent in the middle of their lengths, and the tip portions are inclined towards the lower end portion 16b and are in a zigzag shape. The corner portions on both sides of the edge portion of the locking hole 60 near the upper end portion 16a are rounded and chamfered.

[0023] At the corner portion surrounded by the fold line 18 and the lower end portion 16b, a folding line 64 having the same shape as the folding line 26 of the front surface 14 is provided. At the corner portion surrounded by the side edge portion 16c on the opposite side of the fold line 18 and the lower end portion 16b, a folding line 66 having the same shape as the folding line 28 is also provided.

[0024] At the lower end 16b of the back surface 16, a roughly rectangular bottom 68, identical in shape to the bottom 30, is provided between the fold lines 64 and 66, separated by a fold line 70. The end 68a of the bottom 68 opposite to the fold line 70 is parallel to the fold line 70 and is approximately the same length as the fold line 70. Of the pair of side edges 68b intersecting the end 68a, approximately half that is continuous with the end 68a is a straight line approximately perpendicular to the end 68a, and approximately half that is continuous with the fold line 70 is a straight line that slopes toward the end of the fold line 70 and is continuous with the fold line 70 at an obtuse angle.

[0025] The fold line 70, like the fold line 32, is positioned slightly closer to the center of the back surface 16 than the fold line 18 and the lower end of the side edge 16c. The lower end 16b, like the lower end 14b, is folded at a predetermined obtuse angle near the end of the fold line 70, and has a corner that protrudes downward. The vertex of this corner becomes a leg portion 15. One leg portion 15 is provided on each side of the fold line 70.

[0026] In the adhesive piece 20, one of a pair of ends located approximately perpendicular to the fold line 22 is the upper end 20a, which is located above when in use, and the other end is the lower end 20b. The upper end 20a is located slightly further towards the lower end 14b than the upper end 14a of the front surface 14, and is inclined to approach the lower end 20b as it moves away from the fold line 22. The lower end 20b is continuous with the lower end of the fold line 22, i.e., the lower end 14b, and is inclined to approach the upper end 20a as it moves away from the fold line 22.

[0027] A fold line 72, identical in shape to the fold line 28 on the front surface 14, is provided at the corner enclosed by the fold line 22 and the lower end 20b. The side edge 20c on the opposite side of the fold line 22 is not a straight line, but protrudes laterally in a U-shape in the middle. One end of the fold line 72 continues to the fold line 22 at a position slightly closer to the lower end 20b than the upper end 20a, that is, it continues to the end of the fold line 26 on the front surface 14, and the other end continues to the lower end of the U-shape on the side edge 20c. The middle of the fold line 72 is an arc shape that bulges towards the center of the glued piece 20.

[0028] Next, an example of how to assemble the packaging body 10 of this embodiment will be described. Here, Figure 2 shows the front side of the packaging body forming piece 12 of the packaging body 10, and the folding method in which the surface of the box forming piece 12 becomes convex is called a forward fold, and the folding method in which the back side becomes convex is called a reverse fold.

[0029] First, fold along the crease line 32, overlapping the bottom 30 onto the back of the front 14, then fold along the crease line 36 in the reverse direction, and apply glue 74 to the back of the adhesive piece 34. Fold along the crease line 70, overlapping the bottom 68 onto the back of the back 16. Then fold along the crease line 22, apply glue 76 to the surface of the adhesive piece 20, resulting in the state shown in Figure 3. Figure 3 shows the back side of the packaging forming piece 12 to illustrate the assembly method. Next, fold along the crease line 18, overlapping the back 16 onto the front 14, with the backs facing each other. As a result, the back of the adhesive piece 34 is glued to the surface of the bottom 68 with glue 74, and the surface of the adhesive piece 20 is glued to the back of the back 16 with glue 76, resulting in the folded state shown in Figure 1(a). In this state, the folded packaging 10 made of the packaging forming piece 12 is shipped to the factory that will package the contents. The container in this case is a standing container 78 containing cosmetics, etc. The container 78 has a cylindrical body, the upper end of which is a flat sealing portion 78a, and on the opposite side of the sealing portion 78a is a cylindrical cap 78b that covers the spout. The order of gluing and folding may be other than that described above, and the member to which each adhesive is applied may be the member on the opposite side of the adhesive being applied.

[0030] Next, in the factory where the contents 78 are contained and packaged, the folded packaging form 12 is held by hand and bent so that the front 14 and back 16 bulge out in a direction away from each other, bringing the fold lines 18 and 22 closer together. As shown in Figure 1(b), the fold line 40 is folded in the right direction, then the fold line 44 is folded in the wrong direction, and the folded piece 38 is placed on the back of the front 14 in a folded state, so that the tip 38a of the folded piece 38 protrudes upward from the upper end 14a of the front 14. At this time, the tongue piece 48 protrudes from the part folded at the fold line 44 toward the lower end 14b of the front 14.

[0031] Next, the contents 78 are inserted from the cap 78b side between the front 14 and the back 16. As shown in Figure 1(c), the front 14 and back 16 are pushed outward, and the folded bottoms 30 and 68 are assembled so that the fold lines 32 and 70 are raised at a 90° angle, intersecting the front 14 and back 16 and closing the lower openings of the front 14 and back 16. The fold lines 26, 28, 64, and 66 are naturally folded slightly in a straight line and bulge outward, and the cylindrical body assembled from the front 14 and back 16 becomes hexagonal at the lower ends 14b and 16b, resulting in a shape close to a perfect circle. The upper ends 14a and 16a, however, become elliptical or close to a lens shape. In other words, the gap between the front 14 and back 16 is such that the lower ends 14b and 16b are relatively thicker than the upper ends 14a and 16a. The adhesive piece 20 also has a fold line 72 that overlaps with the fold line 66 of the back surface 16, so that even though the back surface 16 and the adhesive piece 20 are glued together and have double thickness, they can be easily folded in the right direction. The side edge 20c of the adhesive piece 20 is not a straight line, but protrudes laterally in a U-shape in the middle, so that it has a large surface area, while the lower end 20b is short and does not interfere with the trajectory of the bottom 30,68.

[0032] The cap 78b of the contents 78 abuts against the assembled bottom 30,68, and the sealing portion 78a of the contents 78 is located slightly closer to the lower ends 14b,16b than the fold line 44, pressing the tongue 48 protruding from the fold line 44 towards the front 14. Next, the fold of the fold line 44 is restored to its original shape, and the folded piece 38 is returned to its flat state, and the locking piece 52 is inserted into the locking hole 60 on the back surface 16. As a result, the arrow-shaped projections 52a on the left and right of the locking piece 52 lock onto the back surface of the inclined lines at both ends of the cutting line 62, sealing it and making it impossible to pull out. Thus, as shown in Figure 1(d), the folded piece 38 is locked to prevent the contents 78 from being removed, and the packaging of the contents 78 is completed. The tongue 48 inside the cutting line 46 is held down by the sealing portion 78a of the contents 78, so a hole is made in the folded portion 38, and the sealing portion 78a of the contents 78 is exposed in this hole. The sealing portion 78a does not move above the folding line 44. The cap 78b abuts against the bottom portions 30,68 and does not move downward, so the contents 78 is packaged without rattling in the vertical direction. The pair of front and back surfaces 14 and 16 have distinctive external shapes that conform to the shape of the contents 78, with the upper end portions 14a,16a having a lens-shaped cross-section and the lower end portions 14b,16b having a hexagonal cross-section. The thickness between the front surface 14 and the back surface 16 is relatively thicker at the lower end portions 14b,16b than at the upper end portions 14a,16a, so the sides of the contents 78 are covered with little clearance, and there is no rattling in the horizontal direction. The locking piece 52 cannot be pulled out of the locking hole 60, and if strong force is applied to forcibly pull it out, the area around the locking hole 60 or the locking piece 52 will be damaged, indicating that it has been tampered with. A fold line 56 is formed in the center of the locking piece 52, and by slightly folding the locking piece 52 along the fold line 56 to reduce the distance between the pair of protrusions 52a, it becomes easier to insert into the locking hole 60 and harder to remove.

[0033] Next, the method of using the packaging 10 of this embodiment will be described. When displaying it by hanging it in a store, the break line 24 on the front 14 is cut to make a hole that opens to the through-hole 42 of the folded-over piece 38, and a hanging device such as a display hanging rod is inserted through the opened through-hole 42 to hang it. When displaying it on a shelf or other surface, the four legs 15 will abut the surface, allowing it to stand on its own. In both cases, the front 14 is displayed facing the consumer, as shown in Figure 4.

[0034] The tongue 48 on the inside of the cutting line 46 is pressed against the sealing portion 78a of the contents 78, so a hole is created in the folded piece 38, and the sealing portion 78a of the contents 78 is exposed through this hole. When opening the package 10, insert a finger into this hole and lift it up, cut the pair of breaking lines 50, and separate the folded piece 38. This opens the package, and the contents 78 can be removed.

[0035] According to the packaging 10 of this embodiment, a standing container 78 containing cosmetics, etc., can be securely packaged and displayed in stores. The distinctive external shape conforms to the shape of the container 78, preventing the container 78 from rattling. The packaging can be done with a large surface area on the front 14, and by displaying the front 14 facing the consumer, a lot of information such as the product name of the cosmetics, etc. contained in the container 78 can be displayed on the front 14, making a strong impression on the consumer. It is made of paper and does not use plastic, so it has little environmental impact. The break line 50 can be easily cut by simply inserting a finger into the hole formed inside the cut line 46 and pulling, providing an easy-open function. When the locking piece 52 of the folded piece 38 is inserted into the locking hole 60 on the back 16, the projection 52a of the locking piece 52 locks onto the cut line 62, making it impossible to pull out, providing a tamper-proof function. There are two display methods for the packaging 10: hanging type and freestanding type, which can be selected according to the surrounding conditions. The front 14 and back 16 are provided with arc-shaped fold lines 26, 28, 64, and 66. When an item 78 is placed inside, it gently folds in a straight line to become three-dimensional, easily and reliably forming a hexagonal tube that can stand on its own. The adhesive piece 20 also has a fold line 72 that coincides with the fold line 66, so the adhesive piece 20 also folds in a straight line without any problems. The side edge 20c of the adhesive piece 20 has a U-shaped projection in the middle, so while it has a large surface area, the lower end 20b is short and does not interfere with the trajectory of the bottom 30, 68.

[0036] Next, a second embodiment of the present invention will be described with reference to Figures 5 and 6. Here, components similar to those in the above embodiment are denoted by the same reference numerals and their descriptions are omitted. The packaging body 80 of this embodiment is provided by assembling packaging body forming pieces 82 formed by punching out a paper sheet. Figure 6 is an unfolded view of the packaging body forming piece 82 as seen from the surface. The packaging body forming piece 82 has a vertically elongated rectangular front surface 84, and on one of the pair of side edges along the longitudinal direction of the front surface 84, a back surface 86 having the same shape as the front surface 84 is provided, separated by a fold line 88. On the side edge of the front surface 84 opposite to the fold line 88, a glued piece 20 is provided, separated by a break line 23, which is glued to the back surface of the back surface 86 when the packaging body 80 is assembled.

[0037] On the front surface 84, one of a pair of ends located approximately perpendicular to the fold line 88 is the upper end 84a, which is located above when in use, and the opposite end of the front surface 84 from the upper end 84a is the lower end 84c.

[0038] The upper end portion 84a is a straight line approximately perpendicular to the fold line 88. The upper end portion 84a is shorter than the length of the front surface 84 in the direction approximately perpendicular to the fold line 88, and side portions 84b are continuous at both ends of the upper end portion 84a, which are continuous with the ends of the fold line 88 or the ends of the break line 23. The pair of side portions 84b are formed by an arc that curves inward toward the center of the front surface 84. As a result, the front surface 84 takes on the appearance of a deformed hexagon. A rectangular adhesive portion 90 is provided at the upper end portion 84a, separated by a fold line 92. The pair of corners of the adhesive portion 90 located at the ends opposite to the fold line 92 are rounded and chamfered. In the center of the adhesive portion 90, there is a circular break line 24 that forms a through hole into which a hanging device such as a hanging rod is inserted when the product is displayed in a store.

[0039] An opening 94 is provided in the center of the front surface 84. The opening 94 occupies a large area of ​​the front surface 84 and is a long rectangle in the direction along the fold line 88. The upper edge 94a, which is close to the upper end 84a, is an arc shape that bulges toward the upper end 84a, and the lower edge 94b, which is close to the lower end 84c, is a straight line approximately perpendicular to the fold line 88. A pair of side edges 94c that connect the ends of the lower end 84c and the upper edge 94a are approximately parallel to the fold line 88 and perpendicular to the lower edge 94b, and the corners between them and the ends of the lower edge 94b are chamfered. Near both ends of the lower edge 94b, there are fold lines 96 that are continuous with the lower end 84c, and the pair of fold lines 96 are approximately parallel to the fold line 88. The lower end 84c is slightly inclined so that as it approaches the fold line 96, it moves outward from the position of the lower end of the fold line 88 or the break line 23.

[0040] At the lower end 84c of the front 84, a bottom 98 is provided between a pair of fold lines 96, separated by a fold line 100. The bottom 98 is roughly hexagonal and closes the lower opening of the hexagonal shape when the front 84 and back 86 are formed into a cylindrical shape in the assembled state of the packaging 80. The end 98a opposite to the fold line 100 is a straight line parallel to the fold line 100 and is slightly shorter than the fold line 100. In the middle of the end 98a, a locking piece 102, which is an arrow-shaped projection, is provided, separated by a fold line 104. The portions of the locking piece 102 that protrude on both sides in a direction parallel to the fold line 104 become projections 102a that are inserted into and locked by a cutting line 114, which will be described later.

[0041] The back surface 86 has the same shape as the front surface 84 and is enclosed by an upper end 86a, a lower end 86c, a pair of side sections 86b, a crease line 88, and a side edge 86d opposite the crease line 88, forming a deformed hexagon. The upper end 86a has a rectangular adhesive section 91 separated by a break line 93. The break line 93 is formed in the middle by a cutting line 93a, which is a semicircle that bulges towards the center of the back surface 86. Inside the cutting line 93a is a tab 106 that locks the contents 78 in the sealed state. A through hole 42 is provided in the center of the adhesive section 91, into which a suspension device such as a hanging rod is inserted. The through hole 42 approximately coincides with the break line 24 when the back surface 86 is folded back to the front surface 84 along the crease line 88 in the assembled state of the packaging 80. The pair of corners located at the end of the adhesive portion 91 opposite to the break line 93 are rounded and chamfered.

[0042] On the back surface 86, near the lower end 86c, a pair of fold lines 108 are provided that are continuous with the lower end 86c. The pair of fold lines 108 are approximately parallel to the crease line 88. The length of the fold lines 108 is slightly longer than the fold line 96 on the front surface 84. The distance between the pair of fold lines 108 is approximately equal to the distance between the pair of fold lines 96. The lower end 86c is slightly inclined so that as it approaches the fold line 108, it moves outward from the position of the crease line 88 or the lower end of the side edge 86d. The portion continuous with the fold line 108 is cut out in an L-shape.

[0043] At the lower end 86c of the back surface 86, a rectangular flap 110 is provided between a pair of fold lines 108, separated by a fold line 112. In the middle of the fold line 112, a U-shaped cutting line 114 is provided, bulging out from the fold line 112 toward the tip of the flap 110. Both ends of the cutting line 114 are continuous on both sides of the middle of the fold line 112, and the portion continuous with the fold line 112 is folded at an obtuse angle toward the back surface 86. As the fold line 112 approaches the end of the cutting line 114, it is slightly inclined so as to move toward the center of the back surface 86 rather than from the point of intersection with the lower end 86c. The fold line 112 is not provided inside the cutting line 114 and is interrupted. The inside of the cutting line 114 becomes the leg portion 15.

[0044] In the adhesive piece 20, one of a pair of ends located approximately perpendicular to the break line 23 is the upper end 20a, which is located above in the use state, and the other end is the lower end 20b. The upper end 20a is inclined so as it moves away from the break line 23, it approaches the lower end 20b.

[0045] The lower end portion 20b is continuous with the lower end portion of the fracture line 23 and slopes toward the upper end portion 20a as it moves away from the fracture line 23. The side edge portion 20c on the opposite side of the fracture line 23 is not a straight line, and the corner continuous with the lower end portion 20b is cut out in an L-shape.

[0046] Next, an example of how to assemble the packaging body 80 of this embodiment will be described. Here, Figure 6 shows the front side of the packaging body forming piece 82 of the packaging body 80, and the folding method in which the surface of the packaging body forming piece 82 becomes convex is called a forward fold, and the folding method in which the back side becomes convex is called a reverse fold.

[0047] First, the break line 23 is folded in a straight line, and glue 76 is applied to the surface of the adhesive piece 20. Glue 77 is applied to the back surface of the adhesive part 91. Next, the fold line 88 is folded in a straight line, and the back surface 86 is folded to the front surface 84, with the back surfaces facing each other. As a result, the surface of the adhesive piece 20 is glued to the back surface of the back surface 16 by glue 76, and the back surface of the adhesive part 91 is glued to the adhesive part 90 by glue 77, resulting in the folded state shown in Figure 5(a). In this state, the folded packaging body 80 formed by the packaging body forming piece 82 is shipped to the factory that packages the contents. Here again, the contents are standing-type contents 78. The order of gluing and folding may be other than that described above, and the members to which each glue is applied may be the members on the opposite side of the glued parts.

[0048] Next, in the factory where the contents 78 are stored and packaged, the folded package 80 is held by hand and bent so that the front 84 and back 86 bulge out in a direction away from each other, bringing the fold line 88 and the break line 23 closer together.

[0049] Next, the contents 78 are inserted between the front 84 and the back 86 from the openings below the front 84 and back 86, from the side of the sealing portion 78a. As shown in Figure 5(b), the sealing portion 78a of the contents 78 is positioned close to the break line 93, inserted into the cut line 93a, and presses the tongue 106 protruding from the adhesive portion 91 towards the front 84. Because the tongue 106 inside the cut line 93a is pressed down by the sealing portion 78a of the contents 78, a hole is made in the adhesive portion 91, and the sealing portion 78a of the contents 78 is exposed in this hole. The sealing portion 78a does not move above the break line 93.

[0050] Next, the flap 110 is folded 90° along the crease line 112, partially closing the lower end 84c and the lower opening of the back surface 86. Then, the bottom 98 is folded 90° along the crease line 100, overlapping the bottom 98 with the front side of the flap 110. Furthermore, the locking piece 102 is folded 104, and the locking piece 102 is inserted into the cutting line 114 of the back surface 86. As a result, the arrow-shaped projections 102a on the left and right of the locking piece 102 are locked to the back surface of the inclined lines at both ends of the cutting line 114, making it impossible to pull it out. The bottom 98 is locked to the back surface 86, closing almost the entire lower end 84c and the lower opening of the back surface 86, preventing the contents 78 from falling out. Thus, as shown in Figure 5(c), the locking piece 102 is locked to prevent the contents 78 from being removed, and the packaging of the contents 78 is completed. Furthermore, the contents 78 can be seen through the opening 94 on the front 84. The locking piece 102 cannot be pulled out from the cutting line 114, and if strong force is applied to try to pull it out forcibly, the area around the cutting line 114 or the locking piece 102 will break, indicating that it has been tampered with.

[0051] Next, the method of using the packaging 80 of this embodiment will be described. When displaying it by hanging it in a store, the break line 24 of the adhesive part 90 is cut to make a hole that opens to the through hole 42 of the adhesive part 91, and a hanging device such as a display hanging rod is inserted through the opened through hole 42 to hang it. When displaying it on a shelf or other surface, the legs 15 and the lower ends 84c, 86c will come into contact with the surface, allowing it to stand on its own. In all cases, the front 84 should be facing the consumer.

[0052] The inner tab 106 of the cutting line 93a is pressed against the sealing portion 78a of the contents 78, creating a hole in the adhesive portion 91, through which the sealing portion 78a of the contents 78 is exposed. To open the packaging 80, a finger is inserted into this hole and pulled up, the breaking line 93 is cut, separating the adhesive portion 91 from the back surface 86, and the contents 78 is removed. Further pulling the back surface 86 away from the front surface 84 cuts the breaking line 23, and the packaging 80 is disassembled. As a result, if information about the tubed product is printed on the back of the packaging forming piece 82, the consumer can read this information.

[0053] The packaging 80 of this embodiment has the same effects as the above embodiment. An opening 94 is provided on the front 84, allowing the contents 78 to be seen through the opening 94, making it easy for consumers to understand. Adhesive portions 90 and 91 are continuously provided on the front 84 and back 86, increasing the surface area, and allowing information such as the product name of the cosmetics etc. contained in the contents 78 to be displayed over a large area.

[0054] This invention is not limited to the above-described embodiments, and the shape of the folded-over piece and the structure of the locking piece and cutting line that secure the folded-over piece to the back may be other than those described. The shape and structure of the bottom can be freely changed, as long as it can be assembled simply and reliably. The size and shape of the opening provided on the front can also be freely designed.
