Description

Protective bag for cards

The present invention relates to a protective bag for cards such as character cards, playing cards, name tags, slips, vouchers, and various leaflets. More specifically, the outer edge of the four corners of the protective bag is along the outer edge of the arc-shaped four corners of the card, and the inner edge of the four corners in the protective bag and the outer edge of the four arc-shaped corners of the card fit. Relates to protective bags.

This type of protective bag for cards is generally formed in a rectangular shape with a transparent synthetic resin film such as polyvinyl chloride film, and printed on cards such as character cards, playing cards, name tags, slips, vouchers, and various leaflets. It is used as a protective bag that can see through the character design and characters. Moreover, the protective bag for cards is applied as a heading portion of a file or the like, a business card pocket on the back of a product catalog or the like with an adhesive applied on the outer surface.

By the way, recently, popular characters such as Pocket Monsters (registered trademark) are printed, character cards with arcs at the four corners are collected, and one card is displayed in order from the top of the deck of cards on hand. Trading card games are actively played.

However, in the conventional protective bag, since the four corners have right-angled edges, the player feels pain in the hand due to the sharp edges during use, particularly when the card is called a shuffle. In addition to the problem of injuries, the shape of the protective bag does not fit the shape of the card, and the card does not fit in the protective bag. there were.

Therefore, the player personally matches the shape of the protective bag with the shape of the card, and cuts and removes the right-angled edge on the arc with a corner cutter or the like. If the cards in the protective bag are exposed to the outside due to the removal of the corners, not only the corners of the cards are damaged, but also hand oil and sweat adhere to the cards, and further, There were new problems such as dirty cards and dirt on the cards, and improvements were desired.

The technology of Patent Document 1 is known as a conventional protective bag for cards. As shown in FIG. 9, the outer edge 101 of the bottom corner of the protective bag H is cut into an arc shape, and the inner edge 102 of the bottom corner has a corner, although there is no sharp edge. Therefore, in the protective bag H, the inner edge 102 of the bottom corner in the protective bag H and the arc-shaped outer edge of the cards did not fit.

Further, since the protective bag H has a wide bottom seal portion 103 and side seal portion 104, the size of the protective bag H and the cards to be stored are greatly different. It was unsuitable for playing the game with it on.

JP 2011-56837 A

In the present invention, in view of the above circumstances, the outer edges of the four corners of the protective bag are along the outer edges of the arc-shaped four corners of the cards, and the inner edge of the four corners in the protective bag and the outer edges of the arc-shaped four corners of the cards are An object is to provide a protective bag for cards to be fitted.

The protective bag for cards of the first invention is a card in which two rectangular films of the same shape and the same size are overlapped without shifting and the remaining three sides are sealed so that an opening is formed on one side. The protective bag for similar use is characterized in that the four corners are arcuate and the two bottom corners on the bottom side facing the opening are sealed along the shape.
The protective bag for cards according to the second invention is characterized in that, in the first invention, the bottom corner is cut in an arc shape after being thermally welded.
A protective bag for cards according to a third aspect of the present invention is characterized in that, in the second aspect, the pair of side sides are fused and the bottom side is cut after ultrasonic welding.

According to the first invention, since the four corners of the card protection bag are round and the bottom corner is sealed along the shape, when storing cards of the same shape and size as the card protection bag. Because the round corners of the card fit with the round corners of the protective bag for cards, there is no extra sealing, so you can enjoy playing the card game as if you were touching the card itself.

Further, according to the first invention, since the four corners are arcuate, the fingers and the like are not damaged by the sharp corners at the four corners as in the conventional product.

In addition, according to the first invention, a commercially available protective bag for cards having square corners can be cut into arcs by hand, but is not sealed, and all four corners are not sealed. Since the bottom corners are sealed when they are open, the corners of cards that are likely to deteriorate as a result of continued use can be protected, and entry of dust and dirt can also be prevented.

Further, according to the first invention, conventionally, the four corners have a corner shape, and the pair of side sides are sealed to both ends of the opening. Therefore, the opening is narrowed by the seal and is difficult to open. However, since the opening corners on the two opening sides are not sealed, it can be opened to both ends in the width direction, the opening can be easily opened, and cards can be easily put in and out.

According to the second invention, conventionally, although it was possible to melt the film in a straight line, it was difficult to melt the film in an arc, and the four corners were arcs and were sealed along the arc. Since the card protection bag could not be manufactured, instead of fusing the bottom corner, the bottom corner was formed by heat-sealing to form a bottom corner. Can be manufactured.

Further, according to the second invention, when the bottom corner is formed, the two films are solidified by heat welding and integrated to be cut in an arc shape, so that the two films are cut without shifting. At the same time, the trimming loss is obtained by integrating the two films, so that the scattering is suppressed to half and the trimming loss recovery burden is reduced.

According to the third invention, it is difficult to incorporate the process of fusing a film into an arc shape into a manufacturing process that requires high-speed processing, as well as cutting the film into an arc shape itself. In the protective bag, the pair of side sides are melted and the bottom side is cut after being ultrasonically welded. Until the protective bag is manufactured, it is possible to continuously process a series of two sheet-like films, including the process of sealing the bottom corner in an arc and cutting it into an arc together with the opening corner. Therefore, the protective bags for cards can be mass-produced.

corners

6a, 6b on the side of the opening 4 that are formed in an arc shape and are not sealed. As shown in FIG. 2, cards are stored inside and used.

The film 1 is made of a synthetic resin film having transparency such as polypropylene. In addition, the film 1 is good also as other synthetic resin films, such as polyethylene, and is not limited to a polypropylene.

Sides

2a and 2b are formed by fusing. The

side widths

2a and 2b have a narrow seal width so that no extra sealing margin is formed on the side edges, and when storing cards of approximately the same shape and size as the protective bag A for cards. The inner dimension in the width direction of the card protection bag A is substantially the same as the width in the short direction of the stored cards, and the cards fit in the width direction in the card protection bag A.

The bottom 3 is formed by cutting after ultrasonic welding. As with the

sides

2a and 2b, the bottom 3 has a seal width that is narrow so that no extra sealing margin is formed, and accommodates cards that are approximately the same size and size as the protective bag A for cards. In this case, since the opening 4 is not sealed, the inner dimension in the longitudinal direction of the card protection bag A is almost the same as the length in the longitudinal direction of the card to be stored, and the cards are protected for the cards. Fits in the longitudinal direction in the bag A.

The opening 4 is formed so that one side of the two films 1 is not sealed, and cards can be inserted and removed through this opening.

The

bottom corners

5a and 5b are formed by, for example, cutting into a circular arc having a diameter of 1 to 4 mmφ, preferably 3 mmφ after being thermally welded and solidified. The diameters of the

bottom corners

5a and 5b may be appropriately changed depending on the size of cards to be accommodated, and are not limited to the above sizes.

The opening

corners

6a and 6b are formed, for example, by cutting into a circular arc having a diameter of 1 to 4 mmφ, preferably 3 mmφ, so that the opening 4 can be easily opened and cards can be easily inserted and removed. The seal is not done. The diameters of the

opening corners

6a and 6b may be appropriately changed depending on the size of cards to be accommodated, and are not limited to the above sizes.

The

bottom corners

5a and 5b and the

opening corners

6a and 6b are cut in an arc shape, and the

side

2a and 2b and the bottom 3 have a narrow seal width so that no extra sealing margin is formed. Therefore, when storing a card that is almost the same shape and size as the card protection bag A, the card fits inside the card protection bag A, and when playing in a card game, the card itself You can enjoy it as if you were touching it.

Subsequently, a method for manufacturing the protective bag A for cards according to the present invention will be described with reference to FIGS.

As shown in FIG. 3, the manufacturing method of the protective bag A for cards performs ultrasonic welding in the flow direction of the central portion in the width direction of the two long films 11 having a predetermined width. FIG. 4 shows a step ST1 for forming the ultrasonic weld 12 (ultrasonic weld formation process in FIG. 8) and a predetermined interval along the flow direction on the ultrasonic weld 12 by thermal welding. A step of forming a cloisonne-shaped heat-welded portion 13 by welding the cloisonne-shaped portion 14 surrounded by four arcs of the cloisonne crest (hereinafter referred to as cloisonne-shaped) to a size that can accommodate a cloisonne-shaped cutting portion 14 described later. ST2 (cloisonne-shaped heat welded portion forming step in FIG. 8) and the cloisonne-shaped cut portion 14 cut into a size that fits in the cloisonne-shaped heat welded portion 13 to form both ends of the film 11 in the width direction. At the same distance as the cloisonne-shaped heat weld 13 Step ST3 (the process of forming the cloisonne-shaped cut portion etc. in FIG. 8) that cuts the cloisonne shape shown in FIG. 6, step ST4 (ultrasonic welded part cutting / separating step of FIG. 8) for cutting and separating the film 11 into two rows by the ultrasonic welded part 12, and a cloisonne-shaped cut part as shown in FIG. 7. 14 and the step ST5 (melting process of FIG. 8) which cuts the center of the half-cloisonne-shaped cutting part 15 by the fusing part 16 which connects the center in the width direction, and makes it into one bag.

First, in step ST1, in the flow direction of the central portion in the width direction of a two-layer film 11 (a laminated film for packaging) having a predetermined long width that is fed out by continuous feeding, for example, a line-shaped super The sonic welded portion 12 is formed so as to be narrow so as not to allow extra sealing. The ultrasonic weld 12 is not limited to a line shape, but may be a broken line shape, and is not limited to the above shape. The film 11 may be a raw roll in which two films are laminated in advance, or two raw rolls may be provided, and the films may be laminated while being fed out from the raw roll.

Here, as shown in FIG. 7, both ends of the two-layer film 11 that are not sealed correspond to the openings 4 of the protective bags A for cards, which have become one by one after the fusing process of step ST5. . Moreover, the film 11 respond | corresponds to the film 1 of the protection bag A for cards etc. which became one piece each after the fusing process of step ST5.

In step ST2, cloisonne-shaped heat welded portions 13 having a length of 86 mm to 99 mm and a width of 59 mm to 92 mm, for example, are formed on the ultrasonic welded portion 12 at predetermined intervals along the flow direction by thermal welding. In addition, the cloisonne-shaped heat welding part 13 should just be a magnitude | size which can accommodate the cloisonne-shaped cutting part 14, and is not limited to the said magnitude | size. In addition, in order to increase the melting speed for high speed welding, the cloisonne-shaped heat welded portion 13 may be formed by, for example, a cooling roll after heat welding so that the cloisonne-shaped heat welded portion 13 is not melted by overheating. You may provide the cooling process cooled by such as.

In step ST3, for example, at the center of the outer peripheral surface of the roll, the position corresponding to the cloisonne-shaped heat welded portion 13, a cloisonne cutter blade having a diameter of 1 to 4 mmφ, preferably 3 mmφ of each arc portion, A cutting roll having a semi-cloisonne-shaped cutter blade with a diameter of 1 to 4 mmφ, preferably 3 mmφ of each circular arc portion, at both ends in the axial direction of the steel plate, and protruding at least at one location in accordance with the cutting pitch. Then, the film is cut at a desired pitch at equal intervals to form the cloisonne-shaped cut portion 14 and the semi-cloisonne-shaped cut portion 15. The trimming loss after cutting is removed by suction with a suction device or the like.

Here, as shown in FIG. 7, the cloisonne-shaped cut portion 14 cut into a cloisonne shape corresponds to the

bottom corners

5a and 5b of the card protection bag A, and is cut into a half-cloisonne shape cut portion. 15 corresponds to the

opening corners

6a and 6b of the protective bag A for cards.

In step ST4, at the location where the ultrasonic welding part 12 is provided, for example, it is cut into two rows by a slit blade. Note that the cutting process in step ST3 and the cutting separation process in step ST4 may be performed simultaneously.

Here, as shown in FIG. 7, the cut ultrasonic welded portion 12 corresponds to the bottom 3 of the protective bag A for cards.

In step ST5, the center of the cloisonne-shaped cut portion 14 and the half-cloisonne-shaped cut portion 15 is melted by a fusing portion 16 that connects the centers in the width direction to form one bag.

Here, as shown in FIG. 7, the melted portions fused in the width direction correspond to the

sides

2 a and 2 b of the protective bag A for cards.

As described above, conventionally, it is difficult to melt the film in a circular arc shape even though the film can be melted in a straight line, and the four corners are arc-shaped, and the cards are sealed along the arc shape. Since the protective bag A could not be manufactured, the

bottom corners

5a and 5b were not melted, but the

bottom corners

5a and 5b were formed by thermal welding and cutting into arcs. A protective bag A for similar purposes can be manufactured.

Further, when the

bottom corners

5a and 5b are formed, a portion where the two films 11 are solidified by heat welding and integrated is cut into an arc shape, so that the two films 11 are easily cut without being displaced. At the same time, since the two films 11 are integrated into a trimming loss, the scattering is suppressed to half and the trimming loss recovery burden is reduced.

Further, it is difficult to incorporate the process of fusing the film 11 into the arc shape into the manufacturing process that requires high-speed processing, as well as the fusing of the film 11 into the arc shape. In FIG. 3, the pair of

side edges

2a and 2b are melted and the bottom edge 3 is cut after being ultrasonically welded. Until the protective bag A is manufactured, the

bottom corners

5a and 5b are sealed in an arc shape and cut into an arc shape together with the

opening corners

6a and 6b. Since the film 11 can be continuously processed, the protective bags A for cards can be mass-produced.

It should be noted that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.
