Description

  The present invention relates to a packaging box provided with a cylindrical body having four side surfaces and a sealed end type lid for closing one end of the cylindrical body, and more particularly to a packaging box with a zipper for opening.

  A packaging box for packaging medicines, medical syringes, and the like enclosed in a blister pack contains documents describing precautions for use together with the medicines. Then, in a facility such as a hospital, a pharmacist or the like performs an operation of taking out medicines and documents from a large number of packaging boxes. Therefore, this type of packaging box for pharmaceuticals and the like is required to be easy to open, and to be formed with a large and easy-to-take out container opening after opening. There are cases where similar packaging boxes are preferred for uses other than pharmaceuticals.

  Conventionally, as disclosed in, for example, FIGS. 3 and 4 of Patent Document 1, a rectangular cylinder and a seal-end-type lid are provided, and the front plate is separated into a front plate and a front plate constituting the cylinder. There was an easy-open container in which a zipper for opening was provided, and two side plates adjacent to the front plate were provided with a pair of cut lines for separating each side plate up and down. The opening zipper and the pair of cut lines are continuous with each other, tearing the opening zipper, and further breaking the pair of cut lines, thereby separating the upper end portion and the lid portion of the cylindrical body from the front plate and the two side plates. A portion where the upper end portion and the lid portion of the body were provided is opened to become an accommodation outlet.

  Furthermore, an opening zipper 64 is provided on the first and third side plates 16 and 18. The opening zipper 64 has a first break line 66 provided so as to overlap the first crease line 24 starting from the end of the first crease line 24 on the outer lid piece 42 side, and a second fold line. The second rupture line 68 provided so as to overlap the second crease line 26 with the end on the outer lid piece 42 side of the crease line 26 as a starting point, and the first and second break lines 66, 68 are Each of the first side plates 16 reaches substantially the center of the first side plate 16, and the end points thereof are connected by a third broken line 70.

  The third break line 70 starts from the end point of the first break line 66 and crosses the first side plate 16 obliquely (obtuse angle with respect to the first break line 66) to form the second crease line 26. A main breakage portion 70a that reaches the end point of the main breakage portion 70a and an arcuate sub-breakage portion 70b that reaches the end point of the second breakage line 68 through the inside of the third side plate 18 Yes. The inner side surrounded by the first, second and third break lines 66, 68 and 70 is a zipper part 72. As described above, the opening zipper 64 includes the three broken lines 66, 68, and 70 and the zipper portion 72.

  Next, an example of a method for assembling the packaging box 10 will be described. FIG. 2 is a view of the box-forming piece 12 as viewed from the front side. Hereinafter, the folding method in which the front side of the box-forming piece 12 is convex is referred to as normal folding, and the folding method in which the back side is convex is referred to as reverse folding.

  First, the crease line 28 is normally folded and the side plate 20 and the glued piece 22 are overlapped on the first and third side plates 16 and 18. Then, after applying glue on the surface of the glue piece 22, the first crease line 24 is normally folded and the back surface of the end of the second side plate 14 is glued to the glue piece 22. The box forming piece 12 is shipped from the manufacturing factory of the packaging box 10 in this folded state.

  Next, in a factory or the like for packaging the medicine S1 and the document S2, the four crease lines 24, 26, 28, and 30 are each normally folded at 90 degrees, and the two side plates 14, 16, 18, and 20 and the paste pieces 22 are placed. A rectangular cylinder A is formed. In the state of the cylindrical body A, the first side plate 16 faces the side plate 20, and the second and third side plates 14 and 18 continue to the side ends of the first side plate 16, respectively.

  Thereafter, in order to provide a bottom B that closes one end of the cylindrical body A, the side flaps 32 and 48 are each normally folded at 90 degrees with the crease lines 36 and 52, and the inner bottom piece 56 is normally folded at 90 degrees with the crease lines 60. . Then, paste is applied to the surface of the inner bottom piece 56, the outer bottom piece 40 is normally folded at 90 degrees along the crease line 44, and the back surface of the outer bottom piece 40 is glued to the inner bottom piece 56. Now that the end B of the sealed end type that closes one end of the cylinder A is created, the medicine S1 is inserted from the other open end, and the document S2 is placed in the gap between the cylinder A and the medicine S1. Bend into a U shape and insert.

  When the medicine S1 and the document S2 are inserted, the side flaps 34 and 50 are each folded forward at 90 degrees along the crease lines 38 and 54 in order to provide a lid C that closes the other end of the cylinder A. Then, the crease line 62 is normally folded and the inner lid piece 58 is normally folded at 90 degrees. Then, paste is applied to the surface of the inner lid piece 58, the outer lid piece 42 is normally folded at 90 degrees along the crease line 46, and the back surface of the outer lid piece 42 is glued to the inner lid piece 58. Thus, a seal-end type lid C is formed, and the assembled state shown in FIG. 1 is obtained, and the medicine S1 and the document S2 are shipped together with the packaging box 10.

  When opening the packaging box 10, the end of the third side plate 18 is pushed by the finger with the part surrounded by the arc-shaped sub-breaking part 70 b, and the sub-breaking part 70 b is broken to end the zipper part 72. The part is picked and the zipper part 72 is pulled up to break the main breakage part 70a, the first break line 66, and the second break line 68. Then, as shown in FIGS. 3A and 3B, the zipper part 72 and the lid part C are separated from the first, second and third side plates 16, 14, 18 and further the zipper part 72 and the lid. When the part C is pulled up, the contents takeout opening D is formed. This opening operation can be performed with almost one action as a series of operations. The zipper part 72 is separated from the first, second and third side plates 16, 14, 18, but the outer lid piece 42 is glued to the inner lid piece 58, so It does not become garbage.

  When the packaging box 10 is unsealed, the area where more than half of the first side plate 16 and the cover C are located is opened, and a large container outlet D is formed, so that the document bent into a U-shape. S2 can be taken out smoothly, and medicine S1 can also be taken out easily.

  As described above, the packaging box 10 is easy to assemble with a simple structure, and can be easily opened with almost one action by an operation of picking up and pulling up the end of the zipper part 72. Moreover, after opening, the zipper part 72 and the lid part C are separated from the first, second and third side plates 16, 14, 18, and the part where the zipper part 72 and the lid part C were located is greatly opened, An accommodation take-out port D from which the medicine S1 and the document S2 are easily taken out is formed.

  Further, the opening zipper 64 has the secondary fracture portion 70b of the third fracture line 70 provided in an arc shape on the inner side of the third side face plate 18. Therefore, by breaking the secondary fracture line 70b, Since the end portion can be easily picked up and the main fracture portion 70a obliquely crosses the first side plate 16, when the zipper portion 72 is pulled up, the main fracture line 70a and the first and second fractures The lines 66 and 68 can be broken very smoothly.

  In addition, the packaging box of this invention is not limited to the said embodiment. The lid that is opened by the opening operation only needs to include a lid piece continuous to the zipper portion of the opening zipper, and is changed to a configuration other than the lid portion C formed by the outer lid piece 42 and the inner lid piece 58. can do. For example, the side flaps 32 and 48 can be glued to the back surface of the inner lid piece 56, and the side flaps 32 and 48 can be used as the lid portion C. In this case, the crease lines 38, By providing a break line at the position 54, when the above opening operation is performed, the break line naturally breaks, and the lid C can be opened without any problem.

  The third break line only needs to connect end points of the first and second break lines, and is not limited to the layout of the third break line 70. The third break line 70 is composed of a main break portion 70a that crosses the first side plate 16 and a sub break portion 70b that passes through the inside of the third side plate 18, and a zipper is provided by providing the sub break portion 70b. Although it is easy to pick the end of the portion 72, if there is no particular trouble, the sub-breaking portion 70b is omitted, and the end points of the first and second breaking lines are connected only with the main breaking portion 70a, The zipper part 72 may be provided only inside the first side plate 16.

  Of the four side plates connected to each other, the box-forming piece is the first side plate located at one end, the second side plate located at the opposite end, and the first side plate You may make it the structure which provided the paste piece at the edge part of the face plate. In this case, the crease line that divides the first side plate and the glue piece becomes the first crease line, and the first side plate is connected to the second side plate via the second crease line in a cylindrical state. It is continuous.

  In addition, the size of the box, the material, the shape of the bottom, and the like can be appropriately changed according to the application.
