Description

  The present invention relates to a packaging body including a main body including a housing portion for housing an article, and a sheet body joined to the main body so as to cover the entire housing portion.

  DESCRIPTION OF RELATED ART Conventionally, the packaging body provided with the main body which has the accommodating part which accommodates articles | goods, and the sheet body joined to a main body so that an accommodating part is covered is known widely. For example, generally, a packaging body called a blister pack has a concave portion formed as a housing portion in a main body made of hard plastic or the like, and a sheet body made of paperboard or the like is joined to the main body so as to cover the concave portion. Yes.

  In such a blister pack, when taking out the article accommodated in the accommodating portion, the entire sheet body covering the accommodating portion is usually peeled off and separated from the main body. However, if the entire sheet is separated from the main body, it is difficult to reseal the blister pack.

Japanese Utility Model Publication No. 42-9360 JP 2004-123111 A

  Thus, conventionally, a resealable blister pack has been proposed. For example, Patent Document 1 discloses a package including a container (main body) in which a recess (housing portion) is formed, and a base plate portion (sheet body) joined to the container. The base plate portion includes a lower area that covers the recess, and an upper area that continues to the upper side of the lower area across the fold. In such a package, by turning up a part of the lower area, an opening accessible to the recess is formed, and after the opening is formed, the base plate portion is folded along the fold and the upper area is engaged with the lower area. By doing so, the package can be resealed.

  Patent Document 2 discloses a packaging body in which a cover body (main body) is provided with a housing portion and a lid portion having substantially the same size as the housing portion, and the housing portion is covered with a sheet body. In this packaging body, after the sheet body is peeled from the cover body, the main body is folded in two along a folding ruled line provided between the housing portion and the lid portion, and the housing portion is covered with the lid portion. The package can be resealed.

  However, in each of the prior arts such as Patent Documents 1 and 2, there is a problem that the opening formed in the sheet body for taking out the article is larger than the accommodating portion. When the opening is large, it is necessary to enlarge a part for covering the opening for resealing. For example, in Patent Documents 1 and 2, in order to reseal, the main body or the sheet body is made about twice as large as the accommodating portion, and the main body or the sheet body is folded in half, thereby opening the opening. Resealing. In this case, since the size of the package before folding is increased, the conveyance cost and the display space are increased.

  Here, if the opening for taking out the article is made small, the part for covering the opening can be made small, and consequently the entire package can be made small. However, if the opening is small, another problem that it becomes difficult to take out the article is caused.

  Therefore, an object of the present invention is to provide a package in which an article can be easily taken out while reducing the overall size. Another object of the present invention is to provide a package capable of reducing the overall size while being able to be resealed repeatedly.

  The packaging body of the present invention includes a main body having a housing portion that is a recess for housing an article, and a sheet body joined to the main body so as to seal the housing portion, An opening that is provided in the vicinity of one end of the sealing portion and that is accessible at least partially away from the sealing portion and that is accessible in the housing portion. An end surface on the one end side of the accommodating portion includes an inclined surface that is separated from the sheet body as the distance from the one end is increased.

  In a preferred aspect, the sheet body further includes a header portion connected to an end portion of the sealing portion, a crease line for resealing set in the header portion, and the resealing so as to cover the opening portion. And an engaging portion with which the header portion bent along the crease line is engaged.

  In another preferred aspect, the main body further includes a header portion continuous with an end portion of the accommodating portion, and a crease line for resealing provided in the header portion, and the sheet body further includes the And an engaging portion with which the header portion bent along the crease line for resealing is engaged so as to cover the opening.

  In another preferred aspect, the header portion is shorter than the accommodating portion. In another preferred aspect, an angle formed by the end surface on the one end side of the housing portion and the sealing portion is less than 80 degrees.

  The packaging body according to another aspect of the present invention includes an accommodating portion that accommodates an article, a header portion that is continuous with one end of the accommodating portion and shorter than the accommodating portion, and a crease line for resealing provided in the header portion, A main body including a sheet body joined to the main body so as to cover at least the entire housing section, the sheet body being separable from the main body and accessing the housing section by being separated from the main body. A possible opening portion that constitutes an opening that is smaller than the accommodating portion, and an engagement portion that is engaged with a header portion that is folded along the crease line for resealing so as to cover the opening portion. It is characterized by providing.

  In a preferred aspect, the planned opening portion has a position and shape straddling the reseal crease line, and the reseal crease line is exposed to the outside by being separated from the main body.

  In another preferred aspect, the planned opening portion includes a first breaking auxiliary line extending over the entire width at a position overlapping the housing portion in the sheet body, and the first fold line than the crease line for resealing. A second break auxiliary line extending over the entire width at a position away from the break auxiliary line, and the opening planned portion by breaking the sheet body along the first and second break auxiliary lines Is separated from the main body to form the opening.

  In another preferred aspect, the planned opening portion includes a sheet-side fold line extending over the entire width at a position overlapping the housing portion in the sheet body, and the sheet-side fold line from the reseal fold line. A break auxiliary line extending over the entire width at a position away from the line, and the sheet body is broken along the break auxiliary line, and the sheet body is folded along the sheet side crease line. Thus, the opening is formed.

  In another preferred aspect, the end surface on the header portion side of the housing portion includes an inclined surface that is separated from the sheet body as it is separated from the header portion.

  According to the present invention, the end surface on the one end side of the accommodating portion is an inclined surface, and the planned opening portion is provided near one end of the sealing portion. Therefore, if the article is slid on the inclined surface after the opening is formed, the article is directed toward the opening. As a result, the article can be easily taken out even if the opening is small. And the size of the whole packaging body can be restrained small by making opening small.

  In addition, according to another aspect of the present invention, re-sealing is performed by folding a header portion (main body) that is relatively resistant to bending, so that it can be repeatedly resealed as compared to Patent Document 1 in which a sheet body is folded. Moreover, since the header part is shorter than the accommodating part, compared with patent document 2, the size of the whole package can be reduced.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a package 10 that is an embodiment of the present invention. FIG. 2 is a front view of the package 10, and FIG. 3 is a rear view of the package 10. FIG. 4 is a schematic longitudinal sectional view of the package 10. In the drawings, the crease line is indicated by a short broken line, and the auxiliary break line is indicated by a long broken line.

  The package 10 includes a main body 12 made of hard plastic or the like, and a sheet body 14 made of paperboard or the like, and is generally called a “blister pack”. Hereinafter, the side on which the main body 12 is disposed is referred to as “front” or “front surface”, and the side on which the sheet body 14 is disposed is referred to as “rear surface” or “rear surface”. Further, the direction approaching the resealing crease line 20 when viewed from the housing portion 16 is referred to as “upward”, and the direction away from the resealing crease line 20 is referred to as “downward”.

  The package 10 accommodates and packages the article 100. Although the article 100 to be packaged is not particularly limited, the package 10 of the present embodiment is particularly suitable for packaging that is not used up all at once. For example, the article 100 accommodated in the package 10 may be a plurality of articles 100 used one by one, or may be an article 100 used in small quantities (for example, a compress sheet used by cutting). . In addition, the article 100 may be used repeatedly, and after use, the article 100 may be housed in the package 10 to prevent contamination. In the following description, description will be given by taking as an example a package 10 that contains a plurality of medicine packages packaged one by one.

  The main body 12 includes a housing portion 16 and a flange portion 17 that continues to the periphery of the housing portion 16. The main body 12 is composed of a transparent or translucent plastic sheet, and the article 100 accommodated in the accommodating portion 16 can be visually recognized from the outside. The accommodating portion 16 is a portion that accommodates the article 100 and is a concave portion that protrudes forward. In other words, the accommodating portion 16 has a substantially box shape with an open rear end surface. The article 100 is accommodated in the accommodating portion 16 (concave portion). Although the accommodating part 16 is a substantially rectangular shape, the upper end surface 16t of this accommodating part 16 is an inclined surface which advances below as it advances ahead as shown in FIG.1 and FIG.4. Examples of a processing method for forming such a housing portion 16 on a plastic sheet include vacuum forming and pressure forming. The flange portion 17 is a flat surface that extends outward from the periphery of the housing portion 16. The flange portion 17 functions as a margin for joining the sheet body 14.

  As the plastic sheet constituting the main body 12, for example, a transparent sheet that is made of polyester such as polyethylene terephthalate (PET) and is hard and can be thermoformed can be used. In particular, an unstretched amorphous polyester sheet (A-PET). In addition, a single-layer or multi-layer plastic sheet made of polypropylene, polyvinyl chloride, polystyrene, or the like may be used. The thickness is 0.1 mm to 1.0 mm, preferably 0.2 mm to 0.5 mm.

  The sheet body 14 is a sheet-like member joined to the back surface of the main body 12. The material and thickness of the sheet body 14 are not particularly limited, but it is desirable that the sheet body 14 has a certain degree of rigidity, specifically, a rigidity that does not cause unintentional bending or the like in the process of conveying a product. The sheet body 14 is made of, for example, paperboard, a plastic sheet, or the like.

  The sheet body 14 includes a sealing portion 26 joined to the main body 12 to seal the housing portion 16, a header portion 28 connected to an end portion of the sealing portion 26, and a planned opening provided in the sealing portion 26. Part 30 and a crease line 20 for resealing provided in the header part 28. The sealing portion 26 has substantially the same size as the main body 12, and one surface (inner surface) of the sealing portion 26 is joined to the flange portion 17 of the main body 12 with an adhesive or the like. By being joined to the flange portion 17, the opening on the rear end side of the accommodating portion 16 is completely closed by the sealing portion 26. The other surface (outer surface) of the sheet body 14 is exposed to the outside, and various information such as the name of the product, material, usage, and illustration is printed on the outer surface.

  The sealing portion 26 is provided with a substantially rectangular break auxiliary line 32. However, the lower end of the break assisting line 32 is not a straight line, but has a substantially trapezoidal portion that protrudes toward the header portion 28 in the middle. The break auxiliary line 32 assists the breakage of the sheet body 14 and is, for example, a perforation line or a half cut line. When the package 10 is opened, the region surrounded by the break assisting line 32 becomes the planned opening portion 30 that is separated from the main body 12 and forms the opening 40. The planned opening portion 30 is provided near the upper end of the sealing portion 26 (near the end portion on the side of the crease line 20 for resealing). In other words, the planned opening portion 30 is provided at a position facing a part of the upper end surface 16t of the accommodating portion 16 that is an inclined surface. By separating the planned opening portion 30, the housing portion 16 can be accessed and an opening portion smaller than the housing portion 16 is formed.

  The size of the planned opening portion 30 is desirably set according to the size of the article 100 to be accommodated, the amount of information desired to be printed on the sheet member 14, and the like. That is, considering the ease of taking out the article 100, it is desirable that the planned opening 30 is larger. However, as described above, on the outer surface of the sheet member 14, information on the product such as the name of the product, the material, the usage method, and the illustration is printed. Therefore, if the planned opening 30 to be cut off after opening is excessively large, the amount of information remaining after opening (after cutting off the planned opening 30) is reduced. Moreover, although the opening scheduled part 30 is a location used as the opening part 40 after opening, when the said opening part 40 is large, it is necessary to enlarge the header part 28 for covering the said opening part 40 to that extent. That is, if the planned opening 30 is large, the size of the entire package 10 is increased accordingly. Therefore, in order to maintain a sufficient amount of information and reduce the size of the package 10, it is desirable that the planned opening 30 be as small as possible. Therefore, the vertical length of the planned opening portion 30 is preferably 1/2 or less, more preferably 1/3 or less, of the vertical length of the accommodating portion 16. In the present embodiment, the upper end surface 16t of the accommodating portion 16 is an inclined surface so as to maintain ease of taking out while reducing the planned opening portion 30, but this will be described in detail later.

  When the planned opening 30 is cut along the auxiliary breaking line 32, a substantially rectangular opening 40 is formed. At the lower end of the opening 40, an engaging portion 36 protruding toward the header portion 28 side is formed. The engaging portion 36 is a portion that engages with the header portion 28 that is bent along the reseal fold line 20. In the present embodiment, the upper end edge 50 of the header portion 28 is engaged with the engaging portion 36. In order to enable this engagement, the distance Da from the reseal fold line 20 to the upper end edge 50 of the header portion 28 is substantially the same as the distance Db from the reseal crease line 20 to the lower end of the break assist line 32. It has become.

  A header portion 28 is connected to the upper end of the sealing portion 26. The header portion 28 is a flat portion having the same width as the sealing portion 26. As described above, the header portion 28 has substantially the same length as the distance Db from the reseal fold line 20 to the lower end of the break assisting line 32 because of the engagement with the engaging portion 36. However, as in the second embodiment to be described later, if a long hole elongated in the width direction is formed in the header portion 28 and the engagement portion 36 is engaged with one end of the long hole, the header The length of the part 28 is not specifically limited. In this case, the header portion 28 is sized in consideration of the design balance with the accommodating portion 16. However, if the header portion 28 is excessively large, the size of the entire packaging body 10 increases, leading to an increase in transportation cost and the like. Therefore, the header portion 28 is preferably shorter than the housing portion 16. In the present embodiment, the header portion 28 refers to an upper portion of the sheet body 14 from the upper end of the main body 12. A substantially circular hanging hole 22 is formed in the center of the header portion 28 in the height direction.

  In the header portion 28, a crease line 20 for resealing is set over the entire width. When the package 10 once opened is sealed again, the header portion 28 is bent along the crease line 20 for resealing. The reseal fold line 20 is a line that assists or presents the folding of the sheet body 14. The re-sealing crease line 20 is formed by pressing the sheet body 14 linearly with a perforation line in which cut portions and connection portions are alternately arranged, a half cut line that is a groove line having a depth less than the thickness of the sheet body 14, and the like. It can be composed of a pressed ruled line that can be formed. By providing the reseal crease line 20 that assists the folding of the sheet member 14, the header portion 28 can easily swing around the reseal crease line 20. That is, the resealing crease line 20 functions as a hinge portion that swings the header portion 28. Further, the reseal crease line 20 does not necessarily need to “help” the folding, and may be a line that only suggests the folding position. Therefore, the crease line 20 for resealing may be a line printed on the surface of the sheet body 14. That is, the form of the crease line 20 for resealing is not limited as long as it is a part to be folded in the future.

  Next, procedures for opening and resealing the package 10 will be described. When the user wants to open the package body 10, the user breaks the sheet body 14 along the break assisting line 32 to separate the planned opening portion 30 from the sheet body 14 and separate it from the main body 12. FIG. 5 is a schematic cross-sectional view of the package 10 when the planned opening 30 is cut off. As shown in FIG. 5, when the planned opening 30 is cut, an opening 40 is formed near the upper end of the sealing portion 26. The user accesses the inside of the storage unit 16 through the opening 40 and takes out the article 100 stored in the storage unit 16. Here, in this embodiment, the upper end surface 16t of the accommodating part 16 is made into the inclined surface. Thereby, even if the opening part 40 is comparatively small, the articles | goods 100 can be taken out easily. The angle β formed by the upper end surface 16t and the sealing portion 26 is not particularly limited as long as it is less than 90 degrees, but is desirably less than 80 degrees, and more desirably less than 45 degrees. .

  When the upper end surface 16t of the accommodating portion 16 is an inclined surface, the article 100 hitting the inclined surface slides along the inclined surface and easily protrudes outward. Therefore, when taking out the article 100 from the storage unit 16, the user tilts the packaging body 10 so that the inclined surface (upper end face 16t) is on the lower side in the vertical direction, and slides the packaging body 10 or removes the surface of the article 100. The article 100 is moved to the inclined surface side by moving the finger to the inclined surface (upper end surface 16t) side while pressing with the fingers. When the article 100 comes into contact with the inclined surface, the article 100 slides along the inclined surface and jumps out of the recess.

  That is, if the upper end surface 16t of the storage unit 16 is an inclined surface, the user can take out the product 100 without picking up the end of the product 100 in the storage unit 16 with fingers. As a result, the article 100 can be easily taken out even with the small opening 40. Here, since the opening part 40 is formed by separating a part of the sheet body 14 (scheduled opening part 30), the larger the opening part 40, the larger the area of the sheet body 14 that can be separated. In general, the sheet body 14 is printed with information on the article 100 such as the name, use, usage, and raw material of the article 100. It is desirable that such information remain as much as possible even after opening the package 10 without being lost. However, if the area of the planned opening 30 that is separated to form the opening 40 is large, the information printing area is also reduced correspondingly, and the amount of information that can remain is reduced. In the present embodiment, the opening 40 can be made smaller by making the upper end surface of the accommodating portion 16 an inclined surface, and as a result, a large area of information can be left.

  Further, as will be described later, in order to properly reseal, the distance Da from the reseal fold line 20 to the upper end of the header portion 28 is the distance Db from the reseal crease line 20 to the lower end of the planned opening portion 30. It must be more than that. If the opening 40 can be reduced, the distance Da from the crease line 20 for resealing to the upper end of the header 28 can be reduced, and the degree of freedom in setting the size of the header 28 can be improved.

  Next, a procedure for sealing (resealing) the package 10 once opened will be described. In this case, as shown in FIG. 6, the user may fold the header portion 28 along the reseal fold line 20. The folded header portion 28 is overlapped on the back surface of the accommodating portion 16 and covers the opening 40. Then, if the header portion 28 is pressed to the front side and the upper end edge 50 of the header portion 28 is hidden below the engaging portion 36 provided at the upper end of the opening 40, the upper end edge 50, the engaging portion 36, Are engaged with each other, and the movement of the header portion 28 is restricted. If it will be in this state, the state which the opening part 40 was closed by the header part 28 will be maintained, and it can prevent the articles | goods 100 which remain | survived in the accommodating part 16 unintentionally jumping out, and the entrance of dust into the accommodating part 16 .

  Moreover, since the header part 28 is bend | folded by the accommodating part 16 side in the resealed state as evident from FIG. 6, the size of the package 10 can be reduced significantly. Therefore, the space required for storage of the packaging body 10 can be reduced, and the packaging body 10 can be easily carried around.

  When it is desired to take out the article 100 in the accommodating portion 16 again, the header portion 28 may be lifted to expose the opening 40 to the outside. When it is desired to seal again, the header portion 28 may be bent again and engaged with the engaging portion 36. That is, in order to repeatedly perform reseal and re-seal, it is necessary to repeatedly perform folding / unfolding of the header portion 28 (main body 12). Therefore, it is desirable that the sheet body 14 including the header portion 28 is made of a material that is not easily damaged by fatigue even when repeatedly folded and unfolded.

  By the way, such a package 10 is transported or displayed without opening the header portion 28 before opening. If the package 10 before opening is large during the transportation and display, the transportation cost and the necessary display space increase. Since the package 10 of Patent Document 2 is provided with the header portion 28 having the same size as the accommodating portion 16, the size of the package 10 is increased before opening, resulting in an increase in transportation cost and display space. . On the other hand, in the present embodiment, the header portion 28 may have a size that can cover the opening 40. As described above, the opening 40 of the present embodiment is provided only in a part of the accommodating portion 16 and is relatively small. As a result, according to the present embodiment, it is possible to reduce the size of the header portion 28 and, consequently, the entire package 10 before opening. And thereby, transportation cost and display space can be reduced. Further, since the size of the header portion 28 can be freely set regardless of the size of the accommodating portion 16, the degree of freedom in design can be increased.

  As described above, in the present embodiment, when opening, the entire housing portion 16 is not opened, but only a part of the housing portion 16 is opened. Therefore, the planned opening 30 that is separated to form the opening 40 can be reduced in size, and the amount of information missing due to the separation can be reduced. Moreover, in this embodiment, the surface (upper end surface 16t) of the accommodating part 16 on the same side (upper end side) as the planned opening portion 30 is an inclined surface. Therefore, the article 100 can be easily taken out even if the planned opening 30 is reduced. Furthermore, the header part 28 can also be made into a small size by making the opening plan part 30 small, and by extension, the size of the package 10 before opening can be made small.

  In addition, the structure demonstrated so far is an example, the accommodation part 16 whose one end is an inclined surface, the sealing part 26 which seals the said accommodation part 16, and the opening plan provided in the one end vicinity of the sealing part 26 If it is provided with the part 30, another structure may be changed suitably. For example, in the present embodiment, the header portion 28 is provided for resealing, but when resealing is unnecessary or when resealing means is provided separately, the header portion 28 is It may be omitted. In the present embodiment, the upper end edge of the header portion 28 and the engaging portion 36 are engaged with each other. However, the engaging portion 36 may be another portion as long as it is a portion in the folded header portion 28. Engage with the site. Further, the engaging portion 36 may be provided at a location different from the planned opening portion 30.

  In the above description, only the configuration in which the planned opening portion 30 is separated from the sheet body 14 is illustrated, but the planned opening portion 30 can be separated from the main body 12 to form the opening portion 40 as long as the opening portion 40 can be formed. It does not have to be separated from FIGS. 8 and 9 are rear views of the package 10 in which the planned opening 30 is not cut off. As shown in FIG. 8, in this case, the sheet body 14 is provided with an upper side break assisting line 41 and a lower side crease line 42 that extend over the entire width of the sealing portion 26. A region surrounded by the upper fracture auxiliary line 41 and the lower crease line 42 becomes the planned opening portion 30. A substantially semicircular fracture start hole 46 is formed at the upper end of the planned opening 30 in the sheet body 14. The break start hole 46 is a hole that is a break for the break of the sheet body 14 along the upper break assist line 41, and is a hole that intersects the upper break assist line 41 and that can be hooked by the fingertip.

  The lower crease line 42 is a line for assisting the bending of the planned opening portion 30, and is composed of a perforation line, a half cut line, a crease ruled line, and the like. An engaging portion 36 is provided at the approximate center in the width direction of the lower crease line 42. The engaging portion 36 is configured by a substantially trapezoidal cut line 44 that protrudes toward the header portion 18.

  When opening the package 10, the user hooks a fingertip on the break start hole 46 and breaks the sheet body 14 along the upper break assist line 41. As a result, the upper opening portion 30 has a tongue shape in which the upper end is separated from the sheet body 14 and the lower end is connected to the sheet body 14. As shown in FIG. 9, the tongue-shaped opening 30 is bent along a lower crease line 42 to form an opening 40 that is accessible to the housing 16. In this state, the user takes out the article 100 from the opening 40.

  After the article 100 is taken out, the header portion 28 may be bent along the reseal crease line 20 and the opening 40 may be covered with the header portion 18, similarly to the package 10 of FIG. 1. Then, the resealed state is maintained by engaging the bent upper end edge 50 of the header portion 28 with the engaging portion 36.

  As described above, if the planned opening portion 30 is not completely separated, but is folded and bent in a tongue shape, it is possible to eliminate the lack of information associated with opening. That is, according to the form of FIG. 8, FIG. 9, all the sheet | seat bodies 14 with which various information is described remain without being cut off. As a result, the information described on the sheet body 14 is not lost.

  In the form of FIGS. 8 and 9, the tongue-shaped opening 30 is swingable about the lower crease line 42 in the resealed state. When it is desired to prevent the swing of the planned opening portion 30, as shown in FIG. 9, a notch 49 constituting the engaging portion 36 is formed inside the planned opening portion 30, and the header portion 28 is attached to the notch 49. What is necessary is just to make it engage. Of course, in this case, the size of the header portion 18 is changed according to the position of the cut 49. With such a configuration, it is possible to prevent the planned opening 30 from swinging while preventing loss of information.

  Next, a second embodiment will be described. FIG. 10 is a perspective view of the package 10 of the second embodiment. FIG. 11 is a front view of the package 10, and FIG. 12 is a rear view of the package 10. FIG. 13 is a schematic longitudinal sectional view of the package 10.

  The package 10 includes a main body 12 made of hard plastic or the like, and a sheet body 14 made of paperboard or the like, and is generally called a “blister pack”. In the following, the side on which the main body 12 can be seen is called “front” or “front”, and the side on which the sheet body 14 can be seen is called “back” or “rear”. Further, the direction approaching the resealing crease line 20 when viewed from the housing portion 16 is referred to as “upward”, and the direction away from the resealing crease line 20 is referred to as “downward”.

  The package 10 accommodates and packages the article 100. Although the article 100 to be packaged is not particularly limited, the package 10 of the present embodiment is particularly suitable for packaging that is not used up all at once. For example, the article 100 accommodated in the package 10 may be a plurality of articles 100 used one by one, or may be an article 100 used in small quantities (for example, a compress sheet used by cutting). . In addition, the article 100 may be used repeatedly, and after use, the article 100 may be housed in the package 10 to prevent contamination. In the following description, description will be given by taking as an example a package 10 that contains a plurality of medicine packages packaged one by one.

  The main body 12 includes a housing portion 16 and a header portion 18 connected to the upper end of the housing portion 16, and a crease line 20 for resealing is formed in the header portion 18. The main body 12 is made of a transparent or translucent plastic sheet, and the article 100 accommodated in the accommodating portion 16 can be visually recognized from the outside. In the drawings, the crease line is indicated by a short broken line, and the auxiliary break line is indicated by a long broken line.

  The accommodating portion 16 is a portion that accommodates the article 100 and is a concave portion that protrudes forward. The article 100 is accommodated in the accommodating portion 16 (concave portion). Although the accommodating part 16 is a substantially rectangular shape, the upper end surface 16t of this accommodating part 16 is an inclined surface which advances below as it advances ahead as shown in FIG.10 and FIG.13. Examples of a processing method for forming such a housing portion 16 on a plastic sheet include vacuum forming and pressure forming. A flange portion 17 that extends outward is connected to the periphery of the housing portion 16. The flange portion 17 functions as a margin for joining the sheet body 14.

  A header portion 18 is connected to the upper end of the accommodating portion 16. The header portion 18 is a flat portion having the same width as the accommodating portion 16. In the present embodiment, the header portion 18 refers to an upper portion of the main body 12 relative to the housing portion 16. If the header part 18 is shorter than the accommodating part 16, the size will not be specifically limited. Therefore, the header portion 18 is sized in consideration of the design balance with the accommodating portion 16. However, as will be described later, in order to properly re-seal the package 10, the distance D3 from the upper end of the header portion 18 to the re-seal fold line 20 is equal to the re-seal crease line 20 and the lower breaking auxiliary line. It is preferable that the distance D2 to 34 or more.

  A long hole that is long in the width direction is formed in the center of the header portion 18 in the height direction. This long hole functions as a hanging hole 22m used when the packaging body 10 is suspended and displayed. The suspension hole 22m has the same position and shape as a suspension hole 22s of the sheet body 14 to be described later. In the following, when the suspension hole 22m and the suspension hole 22s are not distinguished from each other, the subscripts m and s are omitted and simply referred to as the “suspending hole 22”. Further, the lower end edges 24m and 24s of the suspension hole 22 are simply referred to as “lower end edges 24” when they are not distinguished from each other. As will be described in detail later, at the time of resealing, the lower end edge 24 of the hanging hole 22 is engaged with the engaging portion 36 of the sheet body 14. The width of the suspension hole 22 is preferably such that the substantially central portion of the lower end edge 24 can be easily bent, for example, around 50 mm.

  A re-sealing crease line 20 is formed in the header portion 18 over the entire width. When the package 10 once opened is sealed again, the header portion 18 is bent along the re-sealing crease line 20. The reseal crease line 20 is a line that assists the folding of the plastic sheet constituting the main body 12. The crease line 20 for resealing can be formed by pressing a perforation line in which cut parts and connecting parts are alternately arranged, a half cut line that is a groove line having a depth less than the thickness of the plastic sheet, or a plastic sheet in a linear shape. It can be composed of a pressed ruled line. Moreover, as shown in FIG. 7, the re-sealing crease line 20 may be configured by a ridge having a cross-sectional shape that is a convex arc shape on the front side. In any case, by providing the reseal crease line 20 that assists the folding of the plastic sheet, the header portion 18 can easily swing around the reseal crease line 20. That is, the reseal crease line 20 functions as a hinge portion that swings the header portion 18.

  As the plastic sheet constituting the main body 12, for example, a transparent sheet that is made of polyester such as polyethylene terephthalate (PET) and is hard and can be thermoformed can be used. In particular, an unstretched amorphous polyester sheet (A-PET). In addition, a single-layer or multi-layer plastic sheet made of polypropylene, polyvinyl chloride, polystyrene, or the like may be used. The thickness is 0.1 mm to 1.0 mm, preferably 0.2 mm to 0.5 mm.

  The sheet body 14 is a sheet-like member joined to the back surface of the main body 12. The material and thickness of the sheet body 14 are not particularly limited, but it is desirable that the sheet body 14 has a certain degree of rigidity, specifically, a rigidity that does not cause unintentional bending or the like in the process of conveying a product. The sheet body 14 is made of, for example, paperboard, a plastic sheet, or the like.

  The sheet body 14 has substantially the same size as the main body 12. Further, similarly to the header portion 18, a suspension hole 22 that is long in the width direction is formed above the sheet body 14. One surface (inner surface) of the sheet body 14 is joined to the flange portion 17 and the header portion 18 by an adhesive or the like. However, as will be described in detail later, the planned opening 30 is not bonded to the main body 12. The other surface (outer surface) of the sheet body 14 is exposed to the outside, and various information such as the name of the product, material, usage, and illustration is printed on the outer surface.

  The sheet body 14 is provided with a pair of auxiliary break lines 32 and 34 extending in the width direction. These break assist lines 32 and 34 assist the break of the sheet body 14, and are, for example, perforation lines, half cut lines, and the like. As the perforation lines of the break assisting lines 32 and 34, for example, a so-called paper zipper perforation line in which cut portions having a bent or curved shape as shown in FIG. 19 are provided intermittently may be used. The upper break assist line 32 (second break assist line) is provided slightly (several millimeters) above the reseal crease line 20, that is, at a position away from the lower break assist line 34, and extends over the entire width. It is a break auxiliary line extending in a straight line. Further, the lower fracture auxiliary line 34 (first fracture auxiliary line) is a fracture auxiliary line extending over the entire width at a position overlapping with the accommodating portion 16. However, unlike the upper fracture auxiliary line 32, the lower fracture auxiliary line 34 is not straight, but has a substantially trapezoidal portion that protrudes toward the header portion 18 in the middle.

  When the packaging body 10 is opened, the substantially rectangular area surrounded by the upper and lower break assist lines 32 and 34 becomes the planned opening 30 that is separated from the main body 12 to form the opening 40. The scheduled opening portion 30 overlaps with a part of the accommodating portion 16, and by separating the scheduled opening portion 30, the accommodating portion 16 can be accessed and an opening portion smaller than the accommodating portion is formed. Further, the planned opening portion 30 has a position and shape that straddles the crease line 20 for resealing. Therefore, before opening of the package 10, the planned opening 30 functions as a reinforcing member that covers the crease line 20 for resealing and prevents unintentional bending of the crease line for resealing. Further, when the planned opening 30 is cut to open the package 10, the reseal crease line 20 is exposed to the outside and can be easily folded along the reseal crease line 20.

  The planned opening 30 is not joined to the main body 12 in order to facilitate the separation from the main body 12. Further, in order to facilitate the separation of the planned opening portion 30, the portion of the flange portion 17 of the main body 12 that overlaps the planned opening portion 30 is projected forward, and the planned opening portion 30 and the flange portion 17 ( You may provide the clearance gap where a fingertip is easily caught between the main bodies 12).

  The region 38b and the upper region 38u below the lower breaking assist line 34 are regions that remain bonded to the main body 12 even after the package 10 is opened (after the planned opening 30 is cut off). Among these, at the upper end of the lower remaining region 38b, there is an engaging portion 36 protruding toward the header portion 18 side. The engaging portion 36 is a portion that engages with the header portion 18 that is bent along the reseal fold line 20. In the present embodiment, the lower end edge 24 of the suspension hole 22 is engaged with the locking portion. In order to enable this engagement, the distance D1 from the reseal crease line 20 to the lower end of the hanging hole 22 is substantially the same as the distance D2 from the reseal crease line 20 to the lower fracture auxiliary line 34. It has become.

  Next, procedures for opening and resealing the package 10 will be described. When the user wants to open the package body 10, the user separates the scheduled opening portion 30 from the sheet body 14 and separates it from the main body 12. At this time, the user picks up the planned opening 30 by placing his fingertip on the widthwise end of the planned opening 30. And the width direction edge part of the lifted opening scheduled part 30 is picked with a finger | toe, and it pulls in the width direction. As a result, the sheet body 14 is broken along the upper and lower breaking auxiliary lines 32 and 34, and the planned opening 30 is separated from the sheet body 14 and separated from the main body 12.

  FIG. 14 is a schematic cross-sectional view of the package 10 when the planned opening 30 is cut off. As shown in FIG. 14, when the planned opening portion 30 is cut off, the opening portion 40 is formed on the upper side of the housing portion 16. The user accesses the inside of the storage unit 16 through the opening 40 and takes out the article 100 stored in the storage unit 16. Here, in this embodiment, the upper end surface 16t of the accommodating part 16 is made into the inclined surface. Thereby, even if the opening part 40 is comparatively small, the articles | goods 100 can be taken out easily. The angle α formed by the upper end surface 16t and the header portion 18 is not particularly limited as long as it exceeds 90 degrees, but is desirably 100 degrees or more, and more desirably 135 degrees or more.

  That is, when the upper end surface 16t of the accommodating portion 16 is an inclined surface, the article 100 that has hit the inclined surface slides along the inclined surface and easily protrudes outward. Therefore, when taking out the article 100 from the storage unit 16, the user tilts the packaging body 10 so that the inclined surface (upper end face 16t) is on the lower side in the vertical direction, and slides the packaging body 10 or removes the surface of the article 100. The article 100 is moved to the inclined surface side by moving the finger to the inclined surface (upper end surface 16t) side while pressing with the fingers. When the article 100 comes into contact with the inclined surface, the article 100 slides along the inclined surface and jumps out of the recess.

  That is, if the upper end surface 16t of the storage unit 16 is an inclined surface, the user can take out the product 100 without picking up the end of the product 100 in the storage unit 16 with fingers. As a result, the article 100 can be easily taken out even with the small opening 40. Here, the opening 40 is formed by separating a part of the sheet body 14 (scheduled opening portion 30). Therefore, when the opening is large, the area of the sheet body 14 that can be separated increases accordingly. In general, the sheet body 14 is printed with information on the article 100 such as the name, use, usage, and raw material of the article 100. It is desirable that such information remain as much as possible even after opening the package 10 without being lost. However, if the area of the planned opening 30 that is separated to form the opening 40 is large, the information printing area is also reduced correspondingly, and the amount of information that can remain is reduced. In the present embodiment, the opening 40 can be made smaller by making the upper end surface of the accommodating portion 16 an inclined surface, and as a result, a large area of information can be left.

  Also, as will be described later, in order to properly reseal, the distance D3 from the reseal fold line 20 to the upper end of the header portion 18 is the distance D2 from the reseal crease line 20 to the lower fracture auxiliary line 34. It must be more than that. If the opening 40 can be made smaller, the distance D3 from the reseal fold line 20 to the upper end of the header 18 can be reduced, and the degree of freedom in setting the size of the header 18 can be improved.

  Next, a procedure for sealing (resealing) the package 10 once opened will be described. In this case, as shown in FIG. 15, the user may fold the header portion 18 along the reseal fold line 20. Here, since the crease line 20 for resealing is covered with the sheet body 14 (the planned opening 30) before opening, it cannot be easily folded. However, when the planned opening 30 that covers the crease line 20 for resealing is cut off for opening, the crease line 20 for resealing is exposed to the outside. If it will be in this state, the header part 18 can be easily bent along the crease line 20 for resealing. The folded header portion 18 is overlaid on the back surface of the accommodating portion 16 and covers the opening 40. Then, the header portion 18 is pressed forward, and the lower end edge 24 of the suspension hole 22 provided in the header portion 18 is hidden under the engaging portion 36 provided at the upper end of the lower remaining region 38b. For example, the lower edge 24 and the engaging portion 36 are engaged with each other, and the movement of the header portion 18 is restricted. If it will be in this state, the state which the opening part 40 was closed by the header part 18 will be maintained, and the protrusion of the goods 100 which remain | survived in the accommodating part 16 and the entrance of dust into the accommodating part 16 can be prevented. .

  Moreover, since the header part 18 is bend | folded by the accommodating part 16 side in the resealed state as evident from FIG. 15, the size of the package 10 can be reduced significantly. Therefore, the space required for storage of the packaging body 10 can be reduced, and the packaging body 10 can be easily carried around.

  When it is desired to take out the article 100 in the accommodating portion 16 again, the header portion 18 may be lifted to expose the opening 40 to the outside. When it is desired to seal again, the header portion 18 may be bent again and engaged with the engaging portion 36. That is, in order to repeatedly perform reseal and re-seal, it is necessary to repeatedly perform folding / unfolding of the header portion 18 (main body 12). Therefore, it is desirable that the main body 12 including the header portion 18 is made of a material that is not easily damaged by fatigue even if it is repeatedly bent and unfolded.

  By the way, such a package 10 is transported or displayed without opening the header portion 18 before opening. If the package 10 before opening is large during the transportation and display, the transportation cost and the necessary display space increase. Since the package 10 of Patent Document 2 is provided with the header portion 18 having the same size as the housing portion 16, the size of the package 10 is increased before opening, resulting in an increase in transportation costs and display space. . On the other hand, in the present embodiment, the header portion 18 may have a size that can cover the opening 40. As described above, the opening 40 of the present embodiment is provided only in a part of the accommodating portion 16 and is relatively small. As a result, according to the present embodiment, it is possible to reduce the size of the header portion 18 and thus the entire package 10 before opening. And thereby, transportation cost and display space can be reduced. Further, since the size of the header portion 18 can be freely set regardless of the size of the accommodating portion 16, the degree of freedom in design can be increased.

  Moreover, in this embodiment, the opening plan part 30 is made into the position and shape which straddle the crease line 20 for reseal. Therefore, the crease line 20 for resealing is covered with the sheet body 14 (expected opening portion 30) before opening. In this case, even if it is going to bend along the crease line 20 for resealing, the sheet | seat body 14 becomes obstructive and does not bend easily. That is, before opening, the planned opening portion 30 also functions as a reinforcing member that reinforces the periphery of the crease line 20 so as to inhibit unintended folding of the crease line 20 for resealing. By adopting such a configuration, unintentional bending can be inhibited when the package 10 before opening is transported or displayed.

  As described above, in the present embodiment, when opening, the entire housing portion 16 is not opened, but only a part of the housing portion 16 is opened. Therefore, the planned opening 30 that is separated to form the opening 40 can be reduced in size, and the amount of information missing due to the separation can be reduced. Moreover, the header part 18 can also be made small by making the opening plan part 30 small, and by extension, the size of the package 10 before opening can be made small.

  Moreover, after opening, it can reseal by folding the header part 18. In the present embodiment, since the planned opening portion 30 has a position and a shape that crosses the crease line 20 for resealing, unintentional bending of the crease line 20 for resealing is performed before the planned opening portion 30 is separated (before opening). After the separation (after opening), the header portion 18 can be easily folded along the resealing crease line 20.

  Furthermore, by using the upper end surface 16t of the accommodating portion 16 as an inclined surface, the article 100 can be taken out more easily, and the opening 40 can be made smaller. As a result, it is possible to further reduce the amount of information lost due to the separation of the planned opening portion 30 and to further reduce the size of the header portion 18.

  The configuration described so far is merely an example, and may be changed as appropriate. For example, in the present embodiment, the lower end edge 24 of the suspension hole 22 and the engaging portion 36 are engaged, but the engaging portion 36 is a part in the folded header portion 18. You may engage with another site. For example, the engaging portion 36 may be configured to engage the upper end edge 50 of the header portion 18. FIG. 16 is a rear view of the packaging body 10 in which the engaging portion 36 and the upper end edge 50 of the header portion 18 can be engaged. In this case, as shown in FIG. 16, the suspension hole 22 is not provided in the header portion 18. The distance D3 from the reseal crease line 20 to the upper end of the header portion 18 is substantially the same as the distance D2 from the reseal crease line 20 to the lower fracture auxiliary line 34. In such a package 10, after cutting off the planned opening portion 30, if the header portion 18 is bent along the re-sealing crease line 20, the upper end edge 50 of the header portion 18 is engaged with the engaging portion 36, Resealed state is maintained.

  In such a configuration, the header portion 18 can be made smaller. In this case, the lower remaining region 38b and the header portion 18 hardly overlap when resealed. Therefore, in the resealed state, the back surface of the package 10 can be made into a substantially flat surface with almost no steps.

  In the above description, only the configuration in which the planned opening portion 30 is separated from the sheet body 14 is illustrated, but the planned opening portion 30 can be separated from the main body 12 to form the opening portion 40 as long as the opening portion 40 can be formed. It does not have to be separated from FIGS. 17 and 18 are rear views of the package 10 where the planned opening 30 is not cut off. As shown in FIG. 17, in this case, the sheet body 14 has an upper side break assisting line 32 extending over the entire width at a position above the crease line 20 for resealing, and a full width at a position overlapping the accommodating portion 16. And a sheet-side crease line 42 extending in the direction. A region surrounded by the upper fracture auxiliary line 32 and the sheet-side crease line 42 becomes the planned opening portion 30. A substantially semicircular fracture start hole 46 is formed at the upper end of the planned opening 30 in the sheet body 14. The break start hole 46 is a hole that is a break for the break of the sheet body 14 along the upper break assist line 32, and is a hole that intersects the upper break assist line 32 and can be hooked by the fingertip.

  The sheet-side crease line 42 is a line for assisting the bending of the planned opening 30 and is composed of a perforation line, a half cut line, a crease ruled line, and the like. An engaging portion 36 is provided at the approximate center in the width direction of the sheet side crease line 42. The engaging portion 36 is configured by a substantially trapezoidal cut line 44 that protrudes toward the header portion 18.

  When opening the package 10, the user hooks a fingertip on the break start hole 46 and breaks the sheet body 14 along the upper break assist line 32. As a result, the upper opening portion 30 has a tongue shape in which the upper end is separated from the sheet body 14 and the lower end is connected to the sheet body 14. As shown in FIG. 18, the tongue-shaped opening 30 is bent along a sheet-side crease line 42 to form an opening 40 that is accessible to the housing 16. In this state, the user takes out the article 100 from the opening 40.

  After the article 100 is taken out, the header portion 18 may be bent along the reseal fold line 20 and the opening 40 may be covered with the header portion 18 in the same manner as the package 10 of FIG. At the time of this folding, the crease line 20 for resealing is not covered with the planned opening 30 and can be easily folded. Then, the resealed state is maintained by engaging the bent upper end of the header portion 18 with the engaging portion 36.

  As described above, if the planned opening portion 30 is not completely separated, but is folded and bent in a tongue shape, it is possible to eliminate the lack of information associated with opening. That is, according to the form of FIG. 17, FIG. 18, all the sheet | seat bodies 14 with which various information is described remain without being cut off. As a result, the information described on the sheet body 14 is not lost.

  In the form of FIGS. 17 and 18, the tongue-shaped opening 30 is swingable about the sheet-side crease line 42 in the resealed state. When it is desired to prevent the swing of the planned opening portion 30, as shown in FIG. 18, a cut 49 constituting the engaging portion 36 is formed inside the planned opening portion 30, and the header portion 18 is attached to the cut 49. What is necessary is just to make it engage. Of course, in this case, the size of the header portion 18 is changed according to the position of the cut 49. With such a configuration, it is possible to prevent the planned opening 30 from swinging while preventing loss of information.

  Moreover, in the description so far, the opening opening part 30 is made into the position and shape which straddle the crease line 20 for resealing. However, if the sheet body 14 does not hinder the bending of the header portion 18, the planned opening portion 30 does not necessarily have to straddle the crease line 20 for resealing. For example, the upper fracture assisting line 32 may be configured to substantially coincide with the reseal crease line 20.

  In any case, according to the package 10 of the first embodiment and the second embodiment, the surface (upper end surface 16t) on the same side (upper end side) as the planned opening portion 30 of the accommodating portion 16 is the inclined surface. Yes. Therefore, the article 100 can be easily taken out even if the planned opening 30 is reduced. And the size of the package 10 whole can be made small by making the opening plan part 30 small.
