Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, from the viewpoints of hygiene and miniaturization of the wound state, the roll bag body is mostly charged with static electricity in order to ensure the airtightness inside the bag body and the adhesion between the outer peripheral side and the inner peripheral side of the bag body.

[0006] Therefore, when the user uses it, (1) When attempting to separate the bag body on the downstream side of the extraction direction (hereinafter also referred to as the "front end side") from the next bag body on the upstream side (hereinafter simply referred to as "the next"), it is dragged along and extra is drawn out (hereinafter collectively referred to as the "dragging phenomenon"). (2) Even when trying to store a product in the separated bag body, the bottom side and the front side of the bag body are in close contact and difficult to open (hereinafter collectively referred to as the "difficult-to-open phenomenon"). (3) Due to the weight of the bag body or an unexpected reverse rotation of the roll bag body, the bag body on the front end side comes off from the mountain-shaped cutting guide portion (hereinafter collectively referred to as the "detachment phenomenon"). (4) The detached bag body on the front end side adheres to the roll bag body due to the electrostatic effect, and it becomes impossible to identify where the leading edge portion of the bag body on the front end side is (hereinafter collectively referred to as the "identification failure phenomenon"). Such adverse effects are exerted, and problems such as impairing the usability have occurred.

[0007] For this reason, in Patent Document 1 described above, a proposal has been made to provide a low-resistance member in the mountain-shaped cutting guide portion.

[0008] However, even if, for example, a low-resistance member is provided in the mountain-shaped cutting guide portion, in the configuration disclosed in Citation Document 1 in which the bag body on the front end side is pulled out upward in particular, although the dragging phenomenon in (1) above can be eliminated, the other difficult-to-open phenomenon in (2) above, the detachment phenomenon in (3), and the identification failure phenomenon in (4) still remain, and there has been a problem that the factors hindering the usability cannot be solved.

[0009] An object of the present invention is to provide a roll bag holder that can eliminate defects caused by static electricity and significantly improve usability.

Means for Solving the Problems

[0010] In order to achieve the above object, the device of the present application includes a holding shaft portion that rotatably holds a roll bag body formed by separably connecting a plurality of polyethylene bags and winding them around a cylindrical core material, and a cutting guide portion formed in a mountain shape for cutting off the leading edge side bag body drawn from the roll bag body from the next bag body by the user's operation. A close contact body having adhesiveness is provided in a predetermined range including the apex portion of the cutting guide portion.

[0011] In the device of the present application, in a well-known method of using a roll bag body, that is, by pulling out the leading edge side bag body and pulling it to the root side of the close contact body in a state where the leading edge of the next bag body exceeds the mountain-shaped close contact body, the leading edge side bag body can be cut off from the next bag body from the perforation provided between the leading edge side bag body and the next bag body.

[0012] At this time, since a part of the leading edge side edge of the next bag body can be brought into a close contact state by the adhesive force of the close contact body in a state where a part of the two-layered close contact body side is in close contact, the occurrence of the above-mentioned (1) dragging can be suppressed, the above-mentioned (3) detachment can be suppressed, and further, the occurrence of the above-mentioned (4) identification failure can be suppressed.

[0013] Also, due to the load when pulling the leading edge side bag body, a part of the bag body attached to the close contact body remains in close contact as it is, and another part of the bag body facing the attached part receives the pulling load and separates from one part of the bag body against the frictional force, and can be forcibly opened into a lip shape of a person. Thereby, the above-mentioned (2) problem caused by the electrostatic effect can be solved.

Effects of the Invention

[0014] According to the roll bag holder of the present invention, the problems caused by using static electricity can be solved, and the usability can be greatly improved.

Mode for Carrying Out the Invention

[0016] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, the case where the roll bag holder according to this embodiment is used in a state of being placed on a plane is exemplified. However, in actuality, appropriate usage forms such as using the roll bag holder in a suspended state are possible.

[0017] Also, when the user actually uses it in this placed state, an operation of pulling out the bag body from the roll bag body described later to the front side of oneself is performed. Therefore, in the following description, the directions of up, down, left, right, front, and rear are described based on that state (the directions are exemplified in FIGS. 1 and 2).

[0018] As shown in FIGS. 1 and 2, the roll bag holder 10 is formed by bending and welding a metal frame (for example, a wire rod with a diameter of about 5 mm), and includes a center frame 11, a front frame 12 located on the front side, and a rear frame 13 located on the rear side.

[0019] The center frame 11 includes, integrally, a cutout guide portion 11a formed in a mountain shape on the front side and extending from both sides in the width direction toward the center side, a roll guide portion 11b extending rearward from both lower ends of the cutout guide portion 11a, and a suspension guide portion 11c extending in a front-low rear-high shape from the rear end of the roll guide portion 11b and then bent downward in an L shape.

[0020] The front frame 12 has its central portion connected to the roll guide portion 11b by welding or the like. Both end portions thereof are inclined upward, and a holding shaft portion 14 is provided at its upper end portion 12a for rotatably holding a roll bag body 20 in which a plurality of polyethylene bag bodies 21a, 21b... are separably connected and wound in a roll shape.

[0021] Note that the rear end sides of the respective bag bodies 21a, 21b... are sealed by a sealing portion 23, and a perforation 24 for facilitating separation is provided, for example, between the sealing portion 23 of the foremost bag body 21a and the next bag body 21b at the boundary between the respective bag bodies 21a, 21b...

[0022] The rear frame 13 is connected to the roll guide portion 11b of the center frame 11 by welding or the like. The lower end portion 13a of the rear frame 13 functions as a leg when placed on an installation surface G as a plane together with the lower end portion 12b of the front frame 12.

[0023] Note that when the lower end portion 13a of the rear frame 13 is used in a suspended state by using the suspension guide portion 11c of the center frame 11, in the case of having a wall surface (not shown), it has a function of ensuring a stable state by abutting against the wall surface.

[0024] As described above, in this embodiment, a holding shaft portion 14 that rotatably holds a roll bag body 20 formed by separably connecting a plurality of polyethylene bags 21a, 21b,... and winding them around a cylindrical core material 22, and a cutting guide portion 11a formed in a mountain shape for separating the leading edge side bag 21a drawn from the roll bag body 20 from the next bag 21b by a user's operation are provided. Further, in a predetermined range including the apex portion 11d of the cutting guide portion 11a, an adhering body 15 having adhesiveness is provided.

[0025] For the adhering body 15, for example, those having elasticity such as ethylene propylene rubber, urethane rubber, nitrile rubber, sponge rubber, and silicone rubber are used as its material. Further, on the surface of the adhering body 15, for example, adhesiveness (and peelability) is ensured by providing an acrylic adhesive, a silicone adhesive, a urethane adhesive, a rubber-based adhesive, or the like.

[0026] At this time, for example, an acrylic adhesive is an adhesive made of an acrylic polymer, which can be easily designed from a weak adhesion type to a strong adhesion type, has a high degree of freedom in material design, is excellent in transparency, and also has weather resistance and heat resistance.

[0027] Therefore, when exerting the sticking and peeling effect of the bags 21a, 21b,..., it is desirable to apply a material that can be widely adjusted in physical properties, such as a processing film that requires re-peelability or a bonding tape that requires a strong adhesive force, to the adhesive of the adhering body 15.

[0028] Next, the positional relationship between the adhering body 15 and the roll bag body 20 will be described. The distance W1 from the apex portion 15a of the adhering body 15 to the rotation center P of the roll bag body 20 is desirably within a range that is equal to or greater than the diameter when the roll bag body 20 has the maximum diameter when it is unused, and is less than or equal to the length that maintains the state where the rear end portion of the last bag (21a, 21b,...) is wound around the core material 22 when the leading end portion of the last bag (21a, 21b,...) in the roll bag body 20 that contracts in diameter with use reaches the apex portion 15a of the adhering body 15.

[0029] Here, when the adherend 15 is in the placed state on a plane with the axis of the core material 22 (substantially the same as the rotation center P) horizontal and the bag bodies 21a, 21b ··· at the maximum diameter in the unused state, it is desirable that the apex portion 15a of the adherend 15 is located within the range from below the rotation center P of the roll bag main body 20 to the lower point portion 15b of the adherend 15 being above the lower generatrix of the roll bag main body 20 (height H1).

[0030] In addition, when the adherend 15 is in the placed state on a plane with the axis of the core material 22 horizontal and the bag bodies 21a, 21b ··· at the maximum diameter in the unused state, it is more desirable that the apex portion 15a of the adherend 15 is located within the range from below the rotation point center of the roll bag main body 20 to the lower point portion 15b of the adherend 15 being above the lower generatrix of the core material 22 (height H2).

[0031] The arrangement relationship between the adherend 15 and the bag body 21a (21b ···) will be described. As shown in FIG. 3, with respect to the bag width W2 of the bag body 21a (21b ···), the guide width W3 of the cut guide portion 11a is desirably about 1 / 3 in order to ensure the tearing effect using the perforation 24.

[0032] Also, although the adhesion width W4 of the adherend 15 varies depending on the adhesive strength of the adhesive substance used, in order to appropriately ensure the adhesion and peelability with respect to the next bag body 21b, it is desirable that it is about 1 / 2 with respect to the guide width W3 of the cut guide portion 11a. At this time, the opening angle θ of the cut guide portion 11a is desirably 90° or more.

[0033] Furthermore, the adhesion height H3 from the apex portion 15a to the lower point portion 15b of the adherend 15 is desirably about 1 / 2 with respect to the guide height H4 of the cut guide portion 11a.

[0034] Next, an example of using the bag body 21a will be described. As shown in FIG. 4(A), the user pinches near both ends of the foremost bag body 21a of the roll bag main body 20 and pulls it forward (see the thin arrow in FIG. 4(A)).

[0035] Then, as shown in FIG. 5, the leading end bag body 21a is pulled out until the stitch 24 exceeds the apex portion 15a of the adherend 15.

[0036] From this state, while bringing the next bag body 21b into contact with the adherend 15, it is strongly pulled downward and forward (see the thick arrow in FIG. 4(A)).

[0037] As a result, combined with the state where the next bag body 21b is attached to the adherend 15, the stitch 24 can be easily torn and the leading end bag body 21a can be separated from the next bag body 21b, and the above-mentioned "dragging phenomenon" can be eliminated.

[0038] At this time, on the leading end side of the next bag body 21b, while the bottom surface side 21b1 of the bag is attached to the adherend 15, the pulling load of the user is applied only to the upper surface side 21b2 of the bag.

[0039] As a result, on the leading end side of the next bag body 21b, as shown in FIG. 4(B), the bottom surface side 21b1 and the upper surface side 21b2 of the bag are peeled off (rolled up) in a lip shape.

[0040] As a result, when pulling out and using the next bag body 21b, the opening operation can be facilitated by using the portion peeled off in a lip shape, and the above-mentioned "difficult opening phenomenon" can be naturally eliminated.

[0041] In addition, since the next bag body 21b after separation can maintain the state of being attached to the adherend 15, the occurrence of the "detachment phenomenon" can be suppressed, and the occurrence of the "identification failure phenomenon" can also be suppressed.

[0042] In this way, from the perspective of miniaturizing the sanitary surface and the winding state, although the roll bag body 20 is charged with static electricity to ensure the airtightness inside the bag bodies 21a, 21b... and the adhesion between the outer peripheral side and the inner peripheral side, as shown in the present embodiment, by providing the adhesive body 15 with adhesiveness, any of the "dragging phenomenon" in (1) above, the "difficulty in opening phenomenon" in (2), the "detachment phenomenon" in (3), and the "identification failure phenomenon" in (4) can be eliminated, and the usability can be significantly improved.

[0043] As described above, the roll bag holder 10 according to the present embodiment can achieve the same effect even in the case of a hanging type of spike in the stationary type. In addition to what has been already described above, the methods according to the above-described embodiment and each modification example may be appropriately combined and used.

[0044] Moreover, the configuration of the roll bag holder 10 itself is not particularly limited as long as it has or can have the mountain-shaped cutout guide portion 11a, and it has high versatility. For example, in addition to the wire frame configuration as disclosed in the present embodiment, those adopting a plate-shaped frame or a box-shaped shape, etc., the form is not particularly limited. Also, the roll bag body may be held by an axial member (for example, the roll guide portion 11b), or may be, for example, a tray with an arc-shaped cross section.

[0045] Although not exemplified one by one, the present invention is applicable to the entire roll bag holder in which a user appropriately pulls out and uses a roll bag body formed by separably connecting a plurality of polyethylene-made bag bodies and winding them into a roll shape, and various changes are made and implemented within the scope not departing from the gist thereof.
