Summary of the Invention

Problems to be Solved by the Invention

[0004] In the bag body described in Patent Document 1, after the chuck is once fitted, it becomes difficult to open the chuck. However, in the bag body described in Patent Document 1, although the upper end of the fitting portion is rounded so that the user's fingertips do not catch on the fitting portion, the fitting portion can be opened by separating the adhesive point for opening, and it is impossible to determine whether the fitting portion has been opened after being once sealed.

[0005] Therefore, the object of the present invention is to provide a bag that allows for easy determination of whether or not the contents of the bag have been changed, and a method for operating a game tournament using the bag. [Means for solving the problem]

[0006] To achieve the above objective, the present invention provides a bag that can be used for trading card games with card-shaped contents inside, comprising: a storage section having an opening and capable of storing card-shaped contents inside; and a sealing section provided at the opening, capable of detecting when the opening is unsealed, and preventing the removal of card-shaped contents from the storage section by sealing the opening when card-shaped contents are stored in the storage section, wherein the sealing section seals the opening on the inside of the storage section, preventing the removal of card-shaped contents from the storage section until a predetermined part on the outside of the storage section is damaged, and the bag is not resealable after opening. [Effects of the Invention]

[0007] The present invention provides a bag and a method for operating a game tournament that allows for easy determination of whether or not the contents of the bag have been changed, and a method for operating a game tournament using the bag. [Brief explanation of the drawing]

[0008] [Figure 1] This is a schematic diagram of the bag according to this embodiment. [Figure 2] This is a schematic diagram of the bag according to this embodiment. [Figure 3] This is a schematic diagram of the bag structure according to this embodiment. [Figure 4] This is a schematic diagram of a modified example of the bag according to this embodiment. [Figure 5] This is a flowchart of a game tournament using the bag according to this embodiment. [Modes for carrying out the invention]

[0009] [Embodiment] <Overview of the composition of bag 1> Figures 1 and 2 show an overview of an example of a bag according to this embodiment. Specifically, Figure 1(a) is an overview of how the trading cards 5 are stored in the sleeve 3, and Figure 1(b) is an overview of how the card set 7 is stored in the bag 1. Figure 2 shows an overview of how the card set 7 looks after it has been stored in the bag 1 and sealed.

[0010] The bag 1 according to this embodiment is a bag that can be used for gameplay such as trading card games in a sealed state for storing items (card-shaped items) such as trading cards. The bag 1 is constructed to be transparent so that the front and back surfaces of the stored items can be seen from outside the bag 1. The bag 1 is equipped with a sealing part that allows the player to perceive that the opening for inserting the items is not sealed before it is sealed, and the presence of this sealing part makes it easier for the stored items to be introduced into the bag 1. Furthermore, after the stored items are placed in the bag 1 and the opening is sealed, the stored items cannot be removed from the bag 1 until any part of the outer perimeter of the bag 1 is damaged. Therefore, it is easy to determine whether or not the stored items in the bag 1 have been removed by referring to the damaged state of the bag 1.

[0011] For example, the bag 1 is a bag that can be used for trading card games with trading cards 5 or sleeves 3 containing trading cards 5 inside. As an example, as shown in Figure 1(a), trading cards 5 are stored in sleeves 3 (hereinafter, sleeves 3 containing trading cards 5 will be referred to as card set 7). This constitutes the card set 7 shown in Figure 1(b). Then, as shown in Figure 1(b), card set 7 is stored in bag 1. In this embodiment, an example in which card set 7 is stored in bag 1 is described, but bag 1 may also contain trading cards 5 that are not stored in sleeves 3.

[0012] Specifically, the bag body 1 has a bag-like shape with a front and a rear section facing each other. The bag body 1 has an opening 30 and includes a storage section 10 into which items such as trading cards can be sealed, an adhesive section 200 provided on the edge of the opening 30, and a protective member 210 that covers the adhesive section 200 and protrudes outward from the opening 30 of the bag body 1. The adhesive section 200 and the protective member 210 constitute a sealing section 20. The adhesive section 200 is provided, for example, on the inner surface of the rear section of the bag body 1, on the edge of the opening 30. The protective member 210 functions as a release liner to protect the adhesive section 200, and by removing the protective member 210 from the adhesive section 200, the surface of the adhesive section 200 is exposed. The exposed adhesive section 200 adheres to the inner surface of the front section of the bag body 1, thereby sealing the storage section 10 at the opening 30. The protective member 210 can be made of an opaque material or a transparent material with a predetermined mark or the like applied to it. This makes it easy to detect that the opening 30 is unsealed when the protective member 210 is protecting the adhesive portion 200.

[0013] Furthermore, the protective member 210 functions as a guide to facilitate the introduction of the card set 7 into the storage section 10. That is, as shown in Figure 1(b), by moving the card set 7 along the surface of the protective member 210, the card set 7 is smoothly stored in the storage section 10. After the card set 7 is stored in the storage section 10, the protective member 210 is removed and the adhesive part 200 is bonded to the inner surface of the front of the bag body 1, thereby sealing the opening 30 with the card set 7 stored in the storage section 10, as shown in Figure 2. The adhesive part 200 then bonds the inner surface of the front and the inner surface of the rear of the bag body 1. Therefore, in order to remove the card set 7 from the bag body 1, it is necessary to damage one of the outer edges of the bag body 1. Alternatively, after the inner surface of the front part of the bag 1 and the inner surface of the rear part of the bag 1 are bonded together by the adhesive part 200, if the inner surface of the rear part is peeled off from the inner surface of the front part, traces of peeling failure may appear on the adhesive part 200, and even if an attempt is made to reseal it, the adhesive strength will be insufficient and resealing will be impossible. For this reason, after the card set 7 is removed from the bag 1 (for example, after the outer circumference of the bag 1 is damaged and the bag 1 is opened), it becomes impossible to put the card set 7 back into the bag 1 and reseal it.

[0014] Therefore, according to the bag body 1 of this embodiment, in order to remove the trading cards 5 or card set 7 etc. stored in the storage section 10 to the outside, it is necessary to damage / destroy the bag body 1 itself. Thus, whether or not the contents stored in the bag body 1 have been replaced can be easily determined by checking whether or not the bag body 1 is damaged or destroyed. In addition, in the bag body 1, the protective member 210 protrudes to the outside of the opening 30 before it is removed from the adhesive section 200. Therefore, if the protective member 210 is present, it can be easily determined that the opening 30 is not sealed. Furthermore, when storing items in the storage section 10, the items can be introduced into the storage section 10 along the protective member 210 (or by sliding the protective member 210 on its surface) (i.e., the protective member 210 can be used as a guide), so the items can be easily stored in the bag body 1.

[0015] <Details of Bag 1> Figure 3 shows an example of the configuration of the bag according to this embodiment. Specifically, Figure 3(a) shows an overview of the front view of the bag 1, and Figure 3(b) shows an overview of the cross-section AA of Figure 3(a). Furthermore, Figure 3(c) shows an overview of the cross-section AA when a card-shaped item is stored in the bag 1 and the opening 30 is sealed.

[0016] [Details of the composition of bag 1] The bag 1 can be used for players to play games (for example, trading card games) with card-shaped items placed inside. The bag 1 comprises a storage section 10 having an opening 30, an adhesive section 200 provided on the edge of the opening 30, and a protective member 210 provided on top of the adhesive section 200. The adhesive section 200 and the protective member 210 constitute a sealing section 20.

[0017] (Storage compartment 10) The storage compartment 10 is composed of a front sheet (hereinafter sometimes referred to as the "first sheet") and a rear sheet (hereinafter sometimes referred to as the "second sheet") that are positioned opposite each other. Both the first sheet and the second sheet are roughly rectangular in shape. For example, one side of the first sheet (e.g., the long side) is connected to one side of the second sheet (e.g., the long side), and the other side of the first sheet (e.g., the side opposite to one side of the first sheet) is connected to the other side of the second sheet (e.g., the side opposite to one side of the second sheet). Furthermore, the bottom of the first sheet (e.g., one short side) is connected to the bottom of the second sheet opposite to the bottom of the first sheet (e.g., one short side). This results in a bag-shaped storage section 10 having an open opening 30, where the upper part of the first sheet (for example, the other short side of the first sheet) and the upper part of the second sheet facing the said upper part (for example, the other short side of the second sheet) are not connected. The storage section 10 can also be constructed by folding a single sheet and bonding the edges other than the portion that forms the opening 30 with fusion, adhesive, or the like. Furthermore, the storage section 10 can also be constructed using a method such as integral molding. This results in a storage section 10 having an opening 30 and capable of storing card-shaped items inside.

[0018] The material constituting the storage unit 10 is not limited, but for example, a material having transparency that allows the card-shaped storage item stored inside to be visible from the outside (for example, a polymer material such as polypropylene) can be used. In addition, within the range where the transparency can be ensured, a predetermined pigment may be added to the material. Thereby, a colored storage unit 10 can be configured. Further, the storage unit 10 has a size capable of storing a predetermined card-shaped storage item inside. For example, as shown in FIG. 3(a), the storage unit 10 is substantially rectangular in a front view, and has an inner dimension larger than the size of the card-shaped storage item to be stored. Here, the sizes of the first sheet and the second sheet are substantially the same, and neither sheet has a longer long side than the other sheet. As a result, the storage unit 10 does not have a region protruding outward from the end of the opening 30 at the front or rear of the storage unit 10. Thereby, for example, it is possible to prevent folding back the end of one or the other sheet of the storage unit 10 and bringing the folded sheet into contact with the outer surface of the storage unit 10.

[0019] (Sealing portion 20: Adhesive portion 200, Protective member 210) The sealing portion 20 is provided at the opening 30 of the storage unit 10 and enables the opening 30 to be sealed. Further, the sealing portion 20 enables detection / perception of a state where the opening 30 is not sealed (unsealed state). And the sealing portion 20 prevents the card-shaped storage item from being taken out of the storage unit 10 when the opening 30 is sealed with the card-shaped storage item stored in the storage unit 10. That is, the sealing portion 20 seals the opening 30 inside the storage unit 10, and then prevents the card-shaped storage item from being taken out of the storage unit 10 until a predetermined location outside the storage unit 10 is damaged or destroyed. Also, the sealing portion 20 makes it impossible to reseal the opening 30 after opening the bag body 1 after sealing the opening 30.

[0020] Specifically, the sealing portion 20 includes an adhesive portion 200 that seals the opening 30 and a protective member 210 that protects the surface of the adhesive portion 200 before sealing the opening 30. The adhesive portion 200 is located on the inside of the storage portion 10, at least on the edge portion of the opening 30. For example, as shown in Figure 3(b), if the outer surface of the front portion 100 of the storage portion 10 is the first main surface 10a, the inner surface of the front portion 100 is the first back surface 12a, the outer surface of the rear portion 110 is the second main surface 10b, and the inner surface of the rear portion 110 is the second back surface 12b, then the adhesive portion 200 is located in at least a portion of the edge portion of the opening 30 on the first back surface 12a and / or the second back surface 12b. In the example in Figure 3, the adhesive portion 200 is located on the edge portion 302 of the opening 30 on the second back surface 12b.

[0021] The adhesive portion 200 has a substantially rectangular shape (for example, an elongated rectangle) along the width direction of the storage portion 10 and is provided on the edge of the opening 30. The adhesive portion 200 is provided with a predetermined size and shape at an internal position of the storage portion 10 where the adhesive portion 200 does not come into contact with the card-shaped storage items when the storage portion 10 is filled with card-shaped storage items. If the adhesive portion 200 were provided on the outside of the bag 1 (i.e., on the outer surface of the storage portion 10), it could interfere with smooth gameplay using the bag 1. In other words, if there are protrusions or areas that easily adhere to the outer surface of the bag 1 during trading card games with card-shaped storage items stored in the bag 1, it can easily interfere with gameplay such as shuffling multiple bags 1. Therefore, the adhesive portion 200 is provided on the inside of the storage portion 10 (i.e., inside).

[0022] The adhesive portion 200 can be made using a known adhesive composition or tack agent composition such as a rubber-based, acrylic-based, or silicone-based adhesive. The adhesive composition or tack agent composition constituting the adhesive portion 200 may also contain various additives such as fillers, thickeners, heat-resistant resins, and pigments. The adhesive portion 200 has adhesive strength (i.e., sealing strength) such that, at room temperature, after the opening 30 is sealed by the adhesive portion 200, if a force is applied to the sealed portion to form the opening 30 again (for example, when the edge 304 of the first back surface 12a and the edge 302 of the second back surface 12b are bonded by the adhesive portion 200, and a force is applied to peel the first back surface 12a and the second back surface 12b apart), at least a part of the storage portion 10 (for example, the part near the opening 30) is destroyed, or at least a part of the adhesive portion 200 is peeled and destroyed.

[0023] In other words, after the storage compartment 10 is sealed by the adhesive portion 200, when the storage compartment 10 is opened, the area of ​​the storage compartment 10 where the adhesive portion 200 is provided and the vicinity of that area are destroyed, or at least a part of the adhesive portion 200 peels off and breaks, and the adhesive portion 200 is configured to have an adhesive strength / adhesion strength such that peeling marks are left in the area of ​​the peeled-off area of ​​the adhesive portion 200. The area of ​​the adhesive portion 200 that peels off and breaks is configured such that, after peeling, it is impossible to reattach or press the adhesive portion 200 to the inner surface of the storage compartment 10. Therefore, in this embodiment, once the adhesive portion 200 has peeled off after being attached or pressed, it is impossible to reattach or press it again. If the adhesive portion 200 peels off and breaks, even if an attempt is made to reattach or press it, it is easy to identify whether or not it has peeled off and broken by the presence of peeling marks. Furthermore, the adhesive portion 200 may have sufficient adhesive strength to prevent the opening 30 of the storage portion 10 from being opened unless a force exceeding the force required for peeling and breaking is applied after sealing the opening 30. In this case, instead of peeling and breaking the adhesive portion 200, the sealed storage portion 10 itself is destroyed to remove the card-shaped items stored inside the storage portion 10.

[0024] The protective member 210 is then provided overlapping the adhesive portion 200 located on the edge portion 302, with at least a portion of it protruding from the inside to the outside of the storage portion 10. In other words, the protective member 210 is provided covering the surface of the adhesive portion 200. The opening 30 is sealed by peeling the protective member 210 from the adhesive portion 200 and bonding the adhesive portion 200 to the edge portion inside the storage portion 10 on the opposite side of the adhesive portion 200 (in Figure 3(b), the edge portion 304 of the opening 30 on the first back surface 12a).

[0025] There are no limitations on the material that constitutes the protective member 210, but it can be made using a known material that functions as a release paper or release liner (for example, paper or a polymer resin such as polypropylene). The protective member 210 is configured to cover at least the surface of the adhesive portion 200 and to be exposed to the outside of the storage portion 10 by at least a portion of it protruding from the opening 30. For example, as shown in Figure 3(a), the protective member 210 has a substantially rectangular shape when viewed from the front and is configured to protrude from the opening 30 in a direction away from the storage portion 10. As an example, the protective member 210 can be configured such that, when viewed from the front of the bag body 1, more than half of the length of the protective member 210 in the direction along the longitudinal direction of the bag body 1 protrudes from the storage portion 10. In the example in Figure 3(a), the protective member 210 is rectangular when viewed from the front, and more than half of the side along the longitudinal direction of the bag body 1, that is, more than half of the length of the short side of this protective member 210, protrudes to the outside of the storage portion 10. As a result, more than half of the area of ​​the protective member 210 is exposed to the outside of the storage section 10 when viewed from the front of the bag 1. However, as long as the protective member 210 covers the surface of the adhesive section 200 and the protective member 210 can be peeled off from the adhesive section 200, the length of the protective member 210 protruding from the storage section 10 is not limited to the above and may be shorter.

[0026] Because the protective member 210 protrudes from the opening 30, it can assist in inserting card-shaped storage items into the storage section 10 before the opening 30 is sealed. That is, since the protective member 210 protrudes outward from the opening 30, card-shaped storage items can be moved towards the storage section 10 along the surface 210a of the protective member 210, thereby making it easier to introduce card-shaped storage items into the storage section 10. Also, if the protective member 210 has not been peeled off from the adhesive section 200, the surface of the adhesive section 200 remains protected, and because the protective member 210 protrudes from the opening 30, it is easy to see that the opening 30 is not sealed by visually confirming the presence of the protective member 210. Furthermore, the color of the protective member 210 may be different from the color of the storage section 10, from the viewpoint of making it easy to determine that the protective member 210 is present in the opening 30.

[0027] Then, after storing card-shaped items (for example, a card set 7) in the storage section 10, the protective member 210 is peeled off and removed from the adhesive section 200, and the adhesive section 200 is bonded to the inner edge portion of the storage section 10 opposite a part of the edge portion of the storage section 10 (edge ​​portion 304 in the examples of Figures 3(b) and (c)), thereby sealing the opening 30 as shown in Figure 3(c). As a result, the card-shaped items are stored in the bag 1. Furthermore, since the opening 30 is sealed on the inside of the storage section 10 while the card-shaped items are stored in the storage section 10, it is prevented from removing the card-shaped items from the storage section 10 until a predetermined part on the outside of the storage section 10 is damaged. Furthermore, if the adhesive portion 200 is peeled off from the object after it has adhered to it, traces of peeling and fracture will be left behind. Also, if the bag 1 is opened by damaging a part other than the sealed opening 30, that is, a predetermined location on the outside of the storage portion 10, the bag 1 itself will be damaged, making it impossible to reseal it with the sealing portion 20, and also making it impossible to store card-shaped items in the bag 1.

[0028] An opening may be provided at a predetermined location in the storage section 10 (not shown). The opening can be constructed, for example, by providing a predetermined perforation at a predetermined location in the storage section 10 (for example, a perforation can be provided at a predetermined distance from the lower end of the adhesive section 200 toward the storage section 10). After storing card-shaped items in the bag 1 and sealing the opening 30, the stored card-shaped items can be removed by cutting off the opening. Here, once the opening is opened along the perforation, it cannot be returned to its original state. Therefore, it is easy to detect whether the sealed bag 1 has been opened or not, and it becomes impossible to store card-shaped items in the bag 1 once it has been opened by the opening.

[0029] As described above, the card-shaped contents enclosed in the bag 1 cannot be removed from the bag 1 unless the outer edge of the bag 1 (including the opening 30 sealed by the adhesive portion 200) is damaged, or the opening 30 sealed by the adhesive portion 200, which leaves a peeling mark when peeled after bonding, is opened.

[0030] The card-shaped storage items are, for example, thin plate-shaped or card-shaped items such as trading cards or bags containing trading cards (for example, sleeves for storing trading cards). In addition, predetermined information can be printed on the surface of the storage section 10 (for example, the first main surface 10a and / or the second main surface 10b). Examples of predetermined information include predetermined text (for example, the name of a predetermined tournament), a predetermined logo, and / or a figure or mark of a character exclusive to a predetermined tournament. This allows, for example, a player to participate in a predetermined tournament and play a game using a tournament-exclusive bag 1 containing trading cards, and then use the bag 1 containing the trading cards as a souvenir of their participation in the tournament.

[0031] [Variations of the bag shape] Figure 4 shows an overview of a modified example of the bag according to this embodiment. Specifically, Figure 4(a) shows an example in which the bag 1 has multiple sealing parts, and Figure 4(b) shows an example in which the bag 1 has a trapezoidal sealing part.

[0032] The modified bag has substantially the same structure and function as bag 1, except that the sealing portion has a different structure. Therefore, a detailed explanation is omitted except for the differences.

[0033] (Variation 1) As shown in Figure 4(a), the bag 1a according to Modification 1 comprises a plurality of sealing parts. That is, the bag 1a comprises a plurality of sealing parts provided at the opening 30 of the storage section 10. Specifically, the bag 1a has a plurality of adhesive parts 202 provided at predetermined intervals along the edge of the opening 30, and each of the plurality of adhesive parts 202 is covered by a protective member 212. For example, each of the plurality of adhesive parts 202 may be substantially rectangular in shape, and each of the plurality of protective members 212 may also be substantially rectangular in shape. Each protective member 212 covers at least the corresponding adhesive part 202 and has a shape that protrudes from the opening 30 toward the outside of the storage section 10. In the example of Figure 4(a), each of the plurality of protective members 212 is configured to have an elongated rectangular shape.

[0034] (Modification 2) As shown in Figure 4(b), the bag 1b according to the modified example 2 has a trapezoidal sealing portion. That is, the bag 1b has a trapezoidal sealing portion at the opening 30 of the storage portion 10 when viewed from the front. For example, the bag 1b has a trapezoidal adhesive portion 204 at the edge of the opening 30, and a trapezoidal protective member 214 that covers the adhesive portion 204 and is visible from the front. In the example in Figure 4(b), the adhesive portion 204 and the protective member 214 have a shape that widens in the direction away from the storage portion 10, but this shape may be reversed.

[0035] The shape and number of the sealing portion, which comprises the adhesive portion and protective member, are not limited to those described above. Other shapes and different numbers may be used, as well as different from those in Modification 1 and Modification 2. Furthermore, predetermined information may be printed on the surface of the protective member.

[0036] [How to run a gaming tournament] Figure 5 shows an example of the processing flow in a game tournament using the bag according to this embodiment.

[0037] The bag 1 according to this embodiment (including modified bags; the same applies hereinafter) can be used in a predetermined game tournament (for example, a card game tournament using trading cards). Specifically, the bag 1 can be used in the operation of a game tournament using the bag 1 and predetermined card-shaped storage items (for example, trading cards). In the following description, the case in which the card-shaped storage items are trading cards will be used as an example, but the card-shaped storage items may also be trading cards (card sets) in sleeves.

[0038] First, the player registers a set of trading cards to be used in the game tournament, associated with a player ID that identifies the player, to a designated server provided by the organizer of the game tournament (Step 10; hereafter, Step 10 will be referred to as "S"). The player registers the trading cards they plan to use in the game tournament they are scheduled to participate in, associated with their player ID, to the server via a smartphone or personal computer, for example, which is capable of two-way communication with the server via a communication network such as the internet.

[0039] Then, at the venue of the game tournament, the player places the trading cards registered on the server into a bag 1 provided by the organizer, for example, and then peels off the protective member 210 to seal the opening 30 of the bag 1 (S12). For example, the organizer provides the player with the same number of bags 1 as the number of trading cards to be used in the game, at the reception of the game tournament, etc. Then, the player places one or more trading cards to be used in the game tournament into a bag 1 and seals the opening 30 of each bag 1. If the number of players participating in the game tournament is small, below a predetermined number, the organizer may provide each player with a set of trading cards registered in S10. In this case, each player is provided with a set of trading cards that they have registered on the server, with each trading card already placed in a bag 1 and sealed. Each player can then play the game using the set of trading cards provided by the organizer.

[0040] Next, when players compete in a game, for example, a judge provided by the operator checks whether the trading cards registered on the server match the trading cards stored in bag 1 (S14). The judge checks, for example, using an information terminal for judges that can connect to the server, whether the trading cards registered on the server in association with the player ID match the trading cards stored and sealed in bag 1 by the player corresponding to that player ID. If the trading cards stored in bag 1 match the trading cards registered on the server (Yes in S14), the players start the game using bag 1, which contains the trading cards and has its opening 30 sealed (S18).

[0041] On the other hand, if the trading cards stored in bag 1 do not match the trading cards registered on the server (No. in S14), predetermined processes are executed, such as prompting the player to match the trading cards stored in bag 1 with the trading cards registered on the server, or imposing a predetermined penalty on the player (S16). This makes it easy to confirm whether or not the trading cards stored and sealed in bag 1 have been replaced during the game tournament. Furthermore, in bag 1, if the trading cards are removed after the opening 30 has been sealed with trading cards inside, it is easy to detect that they have been removed. Therefore, it is possible to discourage players from deliberately replacing trading cards stored and sealed in bag 1 during the game tournament. As a result, in the operation of a game tournament using bag 1 according to this embodiment, it is possible to prevent fraud, for example, when a player participates in a game tournament, by using a trading card that is not one of the trading cards that have been registered on the server in advance.

[0042] [Effects of the embodiment] In this embodiment, the bag 1 stores card-shaped items in the storage section 10 and seals the opening 30 with the adhesive section 200. After this, the stored card-shaped items cannot be removed unless any part of the outside of the bag 1 is destroyed or the sealed opening 30 is opened again. Here, the adhesive section 200 of the bag 1 peels off and breaks when the opening 30 is opened again after the adhesive section 200 has adhered to the inner surface of the storage section 10 and the opening 30 has been closed, leaving a peeling mark. Therefore, it is easy to detect that the sealed opening 30 has been opened again. Also, if a part of the storage section 10 is destroyed or the opening is cut to remove the card-shaped items stored in the bag 1, the players and referees can easily perceive the damaged state or the state of the cut opening. As a result, with the bag 1, it is easy to detect whether or not the card-shaped items stored in the bag 1 have been replaced with different card-shaped items.

[0043] Thus, the bag 1 according to this embodiment has both the function of a bag that cannot be repeatedly stored in and removed from the storage section 10 for card-shaped items, and the function of a disposable bag that cannot be reused because it is necessary to damage / destroy the bag 1 when removing the stored card-shaped items.

[0044] Furthermore, in the bag 1, the protective member 210 protrudes outward from the opening 30. This makes it easier for the player to store card-shaped items in the storage section 10. Moreover, because the protective member 210 protrudes outward from the opening 30, even if card-shaped items are placed in the bag 1, it cannot be used in the prescribed card game while the protective member 210 is still present (i.e., in an unsealed state). As a result, if the protective member 210 is still present, it is not only difficult to shuffle multiple bags 1 (because it is difficult, the player's attention will be drawn to removing the protective member 210. Once the protective member 210 is removed, shuffling using the bag 1 becomes easy as the front and back of the storage section 10 are approximately the same size), but the opponent in the game and the referee can also easily perceive that the opening 30 is open.

[0045] Furthermore, the bag 1 can store a card set 7, that is, trading cards 5 placed in sleeves 3. This prevents the trading cards 5 from coming into contact with the adhesive portion 200, and / or prevents the trading cards 5 themselves from being damaged or soiled when the card set 7 stored in the bag 1 is removed.

Furthermore, it should be noted that not all combinations of features described in the embodiments are necessarily essential for solving the problem of the invention.
