Description

[Technical Field]

[0001] The present invention relates to a rectangular parallelepiped case with a header for storing playing cards or trading cards (hereinafter simply referred to as "cards") that require security, and a card product comprising the case and a plurality of cards stored in the case. [Background technology]

[0002] Conventionally, a rectangular parallelepiped case with a header for storing cards requiring security is sealed with the card stored therein and sold as a card product. A purchaser can remove the card from the case by opening the case. When different cards are stored in each card product, the case is sometimes made opaque so that the contents of the stored card cannot be seen at the time of purchase.

[0003] Figure 7 is a perspective view of a conventional case. Figure 7 shows the case in an opened state. Case 50 has a rectangular parallelepiped shape, with header section 51 formed extending from the top of the back surface. When using case 50 to store and seal a card, the card is placed into case 50 from the top surface as shown in Figure 7, left and right flaps 52 and 53 are closed, top surface 54 is placed over the case, and tuck (insertion) 55 formed continuously from top surface 54 is inserted between top surface 54 and back surface 58 to close the case.

[0004] To ensure security and prevent the case 50 from being opened at the time of sale, the case is sealed by applying a seal from both sides of the top surface 54 to the side surfaces 57. In addition to or instead of this seal, the tucks 55 and the back surface 58 may be glued together.

[0005] The purchaser can remove the stickers attached from both sides of top surface 54 to side surfaces 57, and then remove tucks 55 to open top surface 54 as shown in Figure 7, thereby opening the top portion and removing the cards. This case can continue to be used by the purchaser as a case for storing cards even after opening.

[0006] The header portion 51 is used to hang the card product from a hanging rod at the time of sale. For this purpose, the header portion 51 is provided with a hanging hole 56. The card product is hung from a hanging rod that is installed at the sales location and extends horizontally, by inserting the hanging hole 56 into the hanging rod.

[0007] [Patent Document 1] Japanese Patent Application Publication No. 2018-177357 Summary of the Invention [Problem to be solved by the invention]

[0008] With conventional cases 50, when manufacturing a card product by storing a card and sealing the case 50, a step is required to insert the tack 55 between the top surface 54 and the back surface 58. This step is not easy to mechanize, and performing it manually requires labor costs. Even when this step is performed by machine, there are problems with insertion failure and low yield. In particular, when the tack 55 and the back surface 58 are bonded together, this step becomes more complicated and is not easy to mechanize.

[0009] Furthermore, the process of attaching the sticker from the top surface 54 to the side surface 57 is relatively complicated and not easily mechanized, and if this process is done manually, labor costs are required, and even if this process is done by machine, mistakes occur and the yield decreases.

[0010] Also, after the purchaser opens the case, the purchaser can continue to use it as a case to store cards, but at this stage the header part is no longer necessary, and the presence of the header part creates the problem that it is difficult to insert and remove the tack smoothly.

[0011] The present invention has been made in view of the above problems, and has an object to provide a new case and card product. [Means for solving the problem]

[0012] (1) One aspect of the present invention is a rectangular parallelepiped case with a header for storing playing cards or trading cards that require security, which has a front, a back, a right side, a left side, a top, and a bottom. The back has a tear line at its top end and an adhesive portion extending from the tear line. The top has a tab that is continuous with the top end of the front and extends from an end of the back to form a header. The adhesive portion is adhered to the top or the tab, and by separating the back and the adhesive portion along the tear line while the case is sealed, (i) the sealed state of the case is released in a manner that leaves evidence that the case has been opened, and (ii) after opening, the header functions as an insertion portion (tack) and the top functions as an opening and closing lid, so that the case can continue to be used to store the playing cards or trading cards.

[0013] This structure ensures that if the case is opened, evidence of the opening remains on the case, preventing it from being opened before sale, ensuring security. After opening, the header functions as a tack, so it does not get in the way. Furthermore, the manufacturing process does not require the insertion of a tack, and the case can be sealed using only adhesive, allowing for easy mechanization of the manufacturing process and improving yield.

[0014] (2) In the case of (1), the adhesive portion may be adhered to the back surface of the tab, and after opening, the header and the adhesive portion, which are adhered to each other, may function as the insertion portion.

[0015] (3) In the case of (2), the adhesive portion may be configured to be folded back from the top end of the tab so that it is also adhered to the front surface of the tab.

[0016] (4) In the case of (1), the adhesive portion may be adhered to the inside of the top surface, and after opening, the top surface and the adhesive portion, which are adhered to each other, may function as the opening and closing lid.

[0017] (5) In any of the cases (1) to (4), the header may have a hole for suspending the case by inserting a suspension rod therein.

[0018] (6) In any of the cases (1) to (5), the separation line may be configured to be strong enough not to separate under its own weight even when the case is suspended with the playing card or trading card stored inside.

[0019] (7) In any of the cases of (1) to (6), the separation line may have a shape in the center that is convex downward on the back surface to facilitate separation with fingers and to facilitate opening and closing of the opening / closing cover.

[0020] In the cases of (8) and (7), the downwardly convex shape may be a round shape.

[0021] (9) A card product according to one aspect of the present invention has a configuration including a case according to any one of (1) to (8) and a plurality of playing cards or trading cards housed in the case. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0023] Below, several embodiments of the present invention will be described, but the present invention is not limited to the following embodiments, and the technical elements, functions, etc. of the several embodiments can be combined in any manner.

[0024] (Case configuration) FIG. 1 is a perspective view of a case according to an embodiment of the present invention, and FIG. 2 is a developed view of the case according to the embodiment of the present invention. Hereinafter, the surface shown in FIG. 2 will be referred to as the front or outer surface, and the reverse side will be referred to as the back or inner surface. As shown in FIGS. 1 and 2, case 10 has a rectangular parallelepiped shape consisting of a front surface 11, a back surface 12, a right side surface 13, a left side surface 14, a top surface 15, and a bottom surface 16. A header 28 is provided at the upper end of back surface 12 and extends therefrom. Header 28 is composed of a tab 19, an upper overlap portion 20, and a folded portion 21, which are stacked one on top of the other. Header 28 has a hanging hole 29.

[0025] The back surface of the right side surface 13 is adhered to the back surface of the side overlapping portion 17, and the back surface of the bottom surface 16 is adhered to the front surface of the bottom overlapping portion 18.

[0026] The rear surface 12 has a separation line 30 at its upper end and an upper overlap margin 20 as an adhesive portion extending from the separation line. The upper overlap margin 20 has a folded portion 21 extending from its upper end. The upper surface 15 is formed continuously with the front surface 11. The upper surface 15 has a tab 19 extending from the end portion on the rear surface 12 side (the upper end in FIG. 2). This tab 19 becomes part of the header 28.

[0027] The separation line 30 has enough strength to prevent the case 10 containing the card from separating under its own weight when it is hung by the hanging hole 29. The separation line 30 is formed by making intermittent cuts between the back surface 12 and the tag adhesive margin 20.

[0028] 3 is a perspective view illustrating the configuration of the header of the case according to the embodiment of the present invention. The back surface of tab 19 is adhered to the back surface of upper overlap portion 20, and the back surface of folded portion 21 is adhered to the front surface of tab 19. In this manner, in this embodiment, header 28 has a configuration in which tab 19, upper overlap portion 20, and folded portion 21 overlap, ensuring strength.

[0029] (Card product manufacturing method) The process for manufacturing a card product in which cards are housed in the case described above will now be described. The following steps are all performed by the device. The card product manufacturing process includes a folding step and a gluing step for a case 10 that is integrally constructed as shown in Figure 2. A flat case as shown in Figure 2 is prepared. The case is made entirely from a single material, specifically paper.

[0030] First, mountain folds are made between the right side surface 13 and the front surface 11, between the front surface 11 and the left side surface 14, between the left side surface 14 and the back surface 12, and between the back surface 12 and the side overlap margin 17, and then the back surface of the right side surface 13 is bonded to the front surface of the side overlap margin 17 using adhesive. This creates a cylindrical shape with open top and bottom. Next, mountain folds are made in the order of the right bottom flap 22, the left bottom flap 23, the bottom overlap margin 18, and the bottom surface 16, and then the back surface of the bottom surface 16 is bonded to the front surface of the bottom overlap margin 18 using adhesive.

[0031] In this state, a box with a bottom and an open top is formed. In this state, a card is placed inside the case 10. The card may be placed in the case 10 as is, or may be placed in a plastic inner bag before being placed in the case 10.

[0032] After the card is stored, the right top flap 24, the left top flap 25, and the top surface 15 are each folded in a mountain fold, and the area between the top surface 15 and the tab 19 is folded in a valley fold. Then, the back surface of the tab 19 overlaps the back surface of the upper overlapping portion 20, and the back surface of the tab 19 is adhered to the back surface of the upper overlapping portion 20 with an adhesive.

[0033] Furthermore, by folding the upper overlap margin 20 and the folded-back portion 21 in a mountain fold, the front surface of the tab 19 and the back surface of the folded-back portion 21 overlap, and the front surface of the tab 19 and the back surface of the folded-back portion 21 are bonded together with an adhesive. As a result, the header 28 is formed, in which the upper overlap margin 20, tab 19, and folded-back portion 21 are bonded together in this order, extending from the upper end of the back surface 12.

[0034] At this time, the hole 26 of the upper overlap margin 20 and the hole 27 of the folded-back portion 21 overlap, and since the notch of the tab 19 is located at this overlapping portion, the hole 26 and the hole 27 form a hanging hole 29 .

[0035] As described above, the manufacturing process for card products includes the steps of constructing the case 10, inserting the card, and sealing the case. The steps of constructing and sealing the case 10 include folding and gluing, but do not include any complicated steps such as an insertion step, and can be easily mechanized. Furthermore, the absence of any complicated steps allows for a high yield.

[0036] (Operations after purchase) After purchasing the card product, the purchaser can open the case 10 and remove the stored card. After opening the case 10, removing the card from the case 10, and using the card, the purchaser can continue to use the case 10 as a case for storing the card.

[0037] Fig. 4 is a perspective view showing the operation of opening the case according to the embodiment of the present invention. As shown in Fig. 4, when the case 10 is sealed, the back surface 12 is separated from the tag adhesive tab 20 along the separation line 30, thereby releasing the sealed state of the case 10 and opening the case 10. At this time, the case 10 is opened in a manner that leaves evidence that it has been opened.

[0038] In this embodiment, opening that leaves evidence of opening refers to irreversible opening in which the case is separated at the separation line 30 and the back surface 12 and the tag adhesive strip 20 are not reconnected at the separation line 30. With this configuration, if the case 10 is opened before purchase, the open state is irreversibly maintained, so once opened, the case 10 cannot be resealed as if it were unopened, thereby ensuring the security of the card.

[0039] The tear line 30 has a shape in the center that is convex downward on the back surface. Specifically, the convex shape is round, more specifically, an arc shape. When opening the package, pressing a finger against this convex portion makes it easy to tear along the tear line 30 with the finger.

[0040] Fig. 5 is a perspective view showing the operation of closing the case after opening according to an embodiment of the present invention. As shown in Fig. 5, after opening, top surface 15 becomes the top cover, and header 28 functions as a tack, which is an insertion portion. Case 10 can be closed by inserting tack 28 into the inside of back surface 12. Furthermore, top cover 15 opens by removing tack 28, allowing the stored card to be removed. In this case, too, because the center of separation line 30 has a convex shape, tack 28 can be easily removed by placing a finger on this convex portion and pulling it out.

[0041] Furthermore, in this embodiment, as described above, the header 28 is adhered to the tag 19, the tag adhesive tab 20, and the folded-back portion 21 so that they overlap, thereby ensuring strength, which is also effective when the header 28 is used as a tack after the case 10 is opened.

[0042] Furthermore, the part that was the header for hanging the card product when unopened can be used as a tack after opening, so no header remains after opening. Therefore, case 10 can be used as a case without a header after opening.

[0043] (Effects of the embodiment) As described above, in this embodiment, the case manufacturing process does not include the complicated step of inserting tucks, and the case 10 can be constructed and sealed through folding and gluing processes, making it easy to mechanize, thereby reducing manufacturing costs.

[0044] Furthermore, when the case 10 is opened, the tear line 30 is severed in a manner that leaves a trace of the case being opened, and the case is irreversibly opened. Therefore, once opened, it cannot be returned to an unopened state, ensuring the security of the card.

[0045] Furthermore, after opening, the header 28 can be used as a tuck, allowing it to continue to be used as a case for storing used cards, without the header 28 remaining as a header. Therefore, the header 28 does not get in the way, improving usability.

[0046] (Variation) In the above embodiment, a folded portion 21 is further provided on the upper overlap portion 20, and after the upper overlap portion 20 and the tab 19 are bonded together, the folded portion 21 is further folded back and bonded to the tab 19, but alternatively, the folded portion 21 may be omitted.

[0047] In this case, however, the adhesive cross section of the tab 19 and the upper overlap margin 20 is exposed at the upper end of the header 28, reducing the design quality and making the adhered tab 19 and upper overlap margin 20 more likely to peel off from the upper end of the header 28. On the other hand, by providing the folded portion 21, the upper end of the header 28 becomes a mountain-folded portion between the upper overlap margin 20 and the folded portion 21, improving the design quality and further strengthening the adhesion of the header 28.

[0048] In addition, in the above embodiment, the back surface of the tab 19 is adhered to the back surface of the upper overlap portion 20, but instead, the folded portion 21 may be omitted and the front surface of the upper overlap portion 20 may be adhered to the back surface of the top surface 15. In this case, the tab 19 alone becomes the header 28. In this case, a hanging hole is provided in the tab 19.

[0049] In this case, after opening, the upper overlap 20 is adhered to the inner surface of the top surface 15, which becomes the top cover, and the tab 19 functions as a tack by itself. Therefore, a hanging hole is provided in the tab 19 rather than a notch. Even with this configuration, the case 10 is constructed without requiring complicated processes such as insertion, and is irreversibly opened by cutting the separation line 30 in a manner that leaves traces of the opening, and after opening, the tab 19, which functioned as a header when unopened, can be used as a tack.
