Description

  The present invention relates to a binding tool that is attached to a bundled portion of a bag body such as a shopping bag and closes the bag mouth of the bag body.

  Products purchased at retail stores such as convenience stores and supermarkets are often placed in plastic bags, and buyers often take them home or carry them while holding the handbags of the plastic bags. However, depending on the shape and size of the product, it may be difficult to maintain a stable state of the product in the suspended shopping bag.

  In addition, food items stored in lunch boxes and tray-shaped containers are required to maintain a horizontal posture in the suspended plastic bag, so a plastic bag suitable for this has been developed. The actual situation is that the horizontal posture sometimes collapses.

  On the other hand, as a prior art related to the present invention, for example, there is a “bag sealing device” described in Patent Document 1. This “seal for bag” is a seal for sealing a bag mouth of a bag in a closed state so as to be bundled, and has a ring-shaped frame and a flexible frame And a flexible piece that is bent by being pushed by the bag mouth when the bag mouth is inserted into the frame, and sealing the bag mouth.

  When using the “sealing tool for bags” described in Patent Document 1, if the bundled bag mouth is inserted into a ring-shaped frame and the bag sealing tool is pushed toward the bottom of the bag, Can be sealed. In addition, after sealing, the flexible piece projecting toward the inside of the frame body is pressed by the bundled bag mouth and bent into a warped shape, thereby pressing the bag mouth. Can be prevented from moving away from the bag mouth.

  As described above, the “bag sealing device” described in Patent Document 1 has a function of preventing the bag sealing device attached to the bundled bag mouth from moving in a direction away from the bag mouth. The bag can be suitably used for a bag in which the sealed bag mouth is hardly re-sealed, such as a garbage bag when being carried into a garbage collection place.

  However, when the “sealant for bag” is used for a bag that needs to be opened to take out the product in the bag after it is closed once, such as a plastic bag, the resealing operation is extremely difficult. There is a problem of becoming.

  Accordingly, the problem to be solved by the present invention is to provide a binding tool that can be easily attached to and detached from the bag body and can stably hold articles in the bag body in a suspended state. .

  The binding device of the present invention includes a frame-like body having an opening through which a bundled portion of a bag body can be inserted, and a flange projecting in the diameter-expanding direction of the opening on at least a part of the outer periphery of the frame-like body And a section.

  Here, in the binding tool, it is desirable that the shape of the flange portion viewed from the direction penetrating the opening is a polygonal shape, a circular shape, an elliptical shape, an egg shape, or an oval shape.

  Moreover, in the said binding tool, it is desirable that the shape of the said opening part seen from the direction which penetrates the said opening part is circular shape, elliptical shape, an ellipse shape, egg shape, or polygonal shape.

  Furthermore, in the binding tool, a through hole having a smaller inner diameter than the opening can be provided in the flange portion.

  On the other hand, the material of the binding tool is preferably at least one of metal, natural stone, ceramics, synthetic resin, and wood.

  First, the binding tool 10 will be described with reference to FIGS. As shown in FIGS. 1 to 3, the binding tool 10 includes an annular frame-like body 12 having an opening 11 through which a bundled portion 2 of a shopping bag 1 that is one of the bags can be inserted, and a frame-like shape. And a flange portion 13 projecting from the outer periphery of the body 12 in the diameter increasing direction of the opening 11. The shape of the opening 11 viewed from the direction penetrating the opening 11 (the arrow X direction in FIG. 2) is circular. The shopping bag 1 is a common name indicating a bag made of a material such as polyolefin that is handed over at the cash register to put in take-out merchandise.

  The shape of the flange 13 viewed from the direction penetrating the opening 11 is an unequal hexagon. Specifically, an unequal side hexagonal shape in which three long side portions 13a and three short side portions 13b are alternately arranged so as to surround the frame-shaped body 12 is formed. In other words, the shape is such that the three corners of the equilateral triangle are cut out by straight lines parallel to the sides facing the respective corners.

  The three long side portions 13a have the same length, and each has an arc shape that protrudes in the diameter increasing direction of the opening 11 (the direction away from the axis 11a of the opening 11). The three short side portions 13b are also the same length and have a linear shape. The length of the short side portion 13b is about 20% to 21% of the length of the long side portion 13a, but is not limited thereto.

  As shown in FIG. 1, a through hole 14 having an inner diameter smaller than that of the opening 11 is formed in a part of the flange portion 13 (in the vicinity of one short side portion 13 b). The through hole 14 penetrates a part of the flange portion 13 in the thickness 13t direction (in the direction of the axis 11a of the opening 11).

  As shown in FIG. 2, the outer peripheral portion of the flange portion 13 has a curved surface shape that becomes gradually thinner and gradually sharpened as the distance from the axis 11 a of the opening portion 11 increases. The thickness 12t of the frame-like body 12 is larger than the maximum thickness of the flange portion 13 (the thickness of the portion closest to the outer periphery 12a of the frame-like body 12) 13t.

  Although the material of the binding tool 10 of this embodiment is a metal (for example, steel, stainless steel, etc.), since it is not limited to this, other materials, such as a natural stone, ceramics, a synthetic resin, and a timber, can also be employ | adopted. However, if a material having a large specific gravity is employed, a more stable locking state can be obtained when the material is attached to the shopping bag 1 as shown in FIGS.

  In the binding tool 10 of the present embodiment, the flange portion 13 has a maximum outer diameter of about 64 mm, the opening portion 11 has an inner diameter of 35 mm, and the flange portion 13 has a maximum thickness 13t of about 6.5 mm.

The binding tool 10 is kept at a fixed position of the binding part 2 of the shopping bag 1 by the frictional force between the binding part 2 and the weight of the binding tool 10, so that the article 5 in the shopping bag 1 It is effective in maintaining stable. Since the back shape of the binding tool 10 is the same as the front shape of the binding tool 10 shown in FIG. 1, when attaching the binding tool 10 to the shopping bag 1, there is no need to worry about so-called back and front.

  When the binding tool 10 is attached to the shopping bag 1, the bundled portion 2 of the shopping bag 1 in which the article 5 is stored is inserted into the opening 11 of the binding tool 10 from the handbags 3 and 3 side. It is only necessary to move the binding tool 10 toward the bottom 4 of the shopping bag 1 while venting the air in the bag 1. When taking out the article 5 in the shopping bag 1, the binding tool 10 is attached to the hand bag 3 of the shopping bag 1. , 3 can be easily detached from the shopping bag 1 and can be easily attached to and detached from the shopping bag 1. Moreover, since the attaching / detaching operation of the binding tool 10 with respect to the shopping bag 1 can be performed by grasping the flange portion 13 by hand, the workability is also good.

  Next, based on FIG. 4, other usage of the binding tool 10 will be described. As shown in FIG. 4, when the PET bottle 6 containing a drink in the shopping bag 1 is stored in a standing posture, the bundled portion 2 of the shopping bag 1 surrounds the cap 6 a of the PET bottle 6 in the standing posture. When the portion 2 that is wrapped and bundled with the portion of the cap 6a is inserted into the opening 11 of the binding device 10, the binding device 10 is locked at the portion directly above the neck portion 6b of the PET bottle 6 by its own weight.

  As a result, the bundled portion 2 on the bag mouth side of the shopping bag 1 is closed in a purse-like manner with the cap 6a wrapped, and the PET bottle 6 (and the article 5) in the shopping bag 1 is restrained from moving. Therefore, even when the plastic bag 1 is suspended by grasping the hand-holding portions 3 and 3 with the hand, the PET bottle 6 in the plastic bag 1 in the suspended state is stably held in the standing posture (the article 5 is in a horizontal posture). be able to.
