Description

  The present invention relates to a cash register that replaces a plastic bag.

  From the recent environmental awareness, there is a conventional cash register that can be used repeatedly instead of a plastic bag. The cash register is spread in the shopping cart, and after payment is completed, the product is stored in the cash register. The shape is a heel that has a handle sewn to the handle wall of the container that has the same shape as a shopping cart, and as a function to close the opening, a string on the upper edge of the handle wall is tied and the upper edges of the handle wall are pulled together The structure was closed. There is also a drawstring bag as a bag for closing the opening with a string.

  Tying a string every time it is closed is a time-consuming work, and in a structure that shrinks the opening like a drawstring bag, the area that cannot be shrunk increases as the opening gets larger, and there is a problem that a part that remains unclosed is generated. there were. It is an object of the present invention to provide a bag that does not need to be tied with a string and can be easily closed without leaving a large opening.

  In order to achieve the above-mentioned object, a string that is passed through a through part provided on the handle wall of the container is also attached to the lid, and the lid is drawn by pulling the string between the through parts, so that the container can be covered. To do.

  Since the lid is closed in conjunction with pulling the string between the threading parts, there is no need to tie the string every time, and the lid is pulled and closed, so there is no region that cannot be contracted even with a large opening.

  The best mode will be described in the following examples with reference to FIGS.

  FIG. 1 is a perspective view of a main part see-through lid closing process, a handle wall 1 facing and making a pair, a cover wall 2 facing and making a pair, and a rectangular bottom connected to the four lower edges of the wall. It is desirable to form a container 4 with the wall 3, and the container 4 should have the same shape as a shopping cart used for picking up and storing displayed goods in a supermarket or the like. A through-hole 6 may be provided, and the through-hole 6 may be provided by making a hole in the handle wall 1 and reinforcing it with eyelets, but the place where the string is easily grasped is the top edge of the wall. It is desirable to attach in a state of protruding to the edge, and as a specific member of the through portion 6, a ring device 9 is desirable, and the ring device 9 may be a round ring, a square ring, or a triangular ring. The D-ring is preferably used, and the D-ring is attached by using a conventional technique in which a bias tape is wound once and stitched. There may be two places in total, one place on the hand wall 1, but a total of four places, preferably two places on the handle wall 1, and the mounting interval is not limited, but the top edge of the handle wall 1 It is desirable to attach it to the section where it is divided into three equal parts, and the lid 7 is attached to the lid wall 2. The attachment position to the lid 7 may be the top edge of the lid wall 2, or an extra zone is created at the top edge. The inside of the ceiling margin zone may be appropriately lowered, and the ceiling margin zone serves to facilitate the folding of the lid 7 base portion to the inside, and a partial portion of the string 5 passed through the through portion 6 is covered with the lid 7. The lid 7 can be attached to the lid 7 by making a hole in the lid 7 and passing the string 5 or by fixing the string 5 by stitching. It is desirable to create a flat cylindrical shape that opens in the horizontal direction by sewing or bag folding the leading edge located on the opposite side of the base, and the lid 7 is cylindrical The string 5 passed through can be freely slid within the range of the lid tube, and can slide freely, so the length of the string 5 can be adjusted freely. Although the connection part for making 5 into a ring is not displayed, as a method of connecting the end of the string 5 to make a ring, it may be connected with a separate connecting tool or may be tied as a simple method The partial area of the string 5 located between the threading parts 6 is taken as the handle area 8, and by pulling the handle area 8, the lid 7 is drawn to the center of the container body 4 by the string 5 to close the opening of the container body 4 In the closed state, an empty area remains at the tip of the lid 7, so it is possible to close the empty area by providing a tip 10 on the leading edge of the lid 7. Although it is possible to sew, the bag folding part of the lid 7 is appropriately extended, the part shifted to the base from the bag folding part is sewn, and the area beyond the stitching line It is desirable to use the tip piece 10, and when pulling the handle area 8 and pulling the lid 7 from the outside of the lid wall 2, refraction pressure is applied to the top edge of the handle wall 1. It is desirable to reinforce it with 11 and the material of the reinforcing tool 11 may be a hard plate or a rod, or may be a foam material such as urethane that can be bent flexibly, especially reinforcing The area that needs to be between the through part 6 and the base of the lid 5, the reinforcing tool 11 may be divided into right and left between the through part 6 adjacent to the handle area 8, and if the reinforcing tool 11 is divided in two It is also possible to bend and fold the top edge of the handle wall 1, and the material of the bag that is the present invention is a durable type chemical fiber, canvas or denim, which is commonly used for bags such as day bags, A cloth with a certain amount of waist, such as the blue sheet used for construction site covering, is suitable and will be described later with reference to FIGS. For mass production, an artificial resin film such as a poly sheet is suitable.

  FIG. 2 is a perspective view of the main part of the transparent lid opening. The lid 7 can be opened inside the lid wall 2, but the container 2 is packed with purchased items after the settlement, so the lid 2 It is desirable to hang the lid 7 on the outside of the lid wall 2 because it is difficult to get caught between the purchase and the lid wall 2, and the method of hanging the lid 7 on the outside hangs the lid 7 on the shopping cart. The body 4 can also be fixed, and the ring 9 which is the through portion 6 is attached above the top edge of the handle wall 1, so that the string 5 is on the top edge of the body 4 The handle area 8 can be easily picked up, and if there is a purchase in the container 4, even if the handle area 8 is pulled up, there is its own weight, so the container 4 will not be lifted together and the lids 7 will not be lifted. If there is little purchase and the weight of the container 4 is light, pulling the handle area 8 in the horizontal direction can pull the lids 7 together, and the string 5 to the cylindrical lid 7 The Since the length of the string 5 can be adjusted within the range of the lid 7 and the lid 7 hanging from the outside of the lid wall 2 is pulled up by pulling the handle area 8, the top edge of the handle wall 1 Although the refraction pressure is applied, the reinforcer 11 reinforces it to prevent refraction, and the area that requires reinforcement is particularly between the ring 9 and the lid 7 base, and the lid 7 is purchased. If it is hung on the edge of the basket and opened, it becomes easier to store the purchase in the container 4.

  FIG. 3 is a perspective view of the main part of the transparent lid closed. By simply pulling up the handle area 8, the pair of lids 7 are pulled together and closed, and the tip piece 10 is provided at the tip of the lid 7. , It can close the empty area between the leading edges of the lid 7, the handle area 8 can be used as a handle to carry the body 4 and can be held by hand, by changing the length of the string 5 It can be hung on the shoulder, and as a method of adjusting the length of the string 5 pulled out, a knot can be made in the middle of the string 5 or a string fixing tool used in a drawstring bag etc. can be attached. You can control the shrinkage of the lid 7 by putting a pipe in the lid 7 and passing the string 5 through the pipe, and if you make the pipe cylindrical, the pipe also serves as a roller When the lid 7 becomes lighter and the container 4 is packed with purchases, the surrounding side wall tends to bulge out. In addition to pulling the lid 7, the string 5 also pulls the handle wall 1 to prevent the container body 4 from bulging out, and the opening of the container body 4 is connected to the string as in the prior art. Since the lid 7 is pulled and closed without closing, there is no leftover like a drawstring bag closing the edge of the opening and the handle wall 1 and the lid wall 2 may be rectangular. For the purpose of stacking, the shopping cart used in the store has an upside down trapezoidal shape, and it is desirable to have the same shape in the case 4 as well. It can be overlaid perfectly.

  FIG. 4 is a perspective view of the main part see-through lid opening, and the lid 7 may be rectangular. However, if the trapezoid is a tapered trapezoid, the tip becomes lighter and easier to draw. The name is the outer membrane 12 near the lid wall 2, the inner membrane 13 is far away, the outer membrane 12 forms a trapezoid of the same shape as the lid 7, and the inner curtain 13 has a rectangular base with an appropriately narrowed base It is desirable that the area deleted to make the inner curtain 13 thinner is the deletion area 14. The deletion area 14 is a place where the string 5 can be put, and it is important that the string 5 does not come off from the upper corner of the lid wall 2. In order to prevent the string 5 from being caught at the corner and the lid 7 from being pulled up and the string 5 coming off, the top edge of the handle wall 1 is appropriately raised above the lid wall 2 to form a step 15. Preferably, the step 15 serves to block the string 5 from falling off, and the reinforcing tool 11 shown in FIG. It may be caused to project from Tekabe 1 on both sides, if the said projecting shape, stiffeners 11 that protrudes is also made to the role of the rod applied to the shopping cart.

  FIG. 5 is a perspective view of the main part see-through lid closing process of the mass production type a cylinder lid type. Since the mass production type is manufactured by welding, it is desirable to use an artificial resin film such as a poly sheet as a material. The durable type up to 4 was processed from a flat body because cloth was the material, but the mass-produced type was processed from a cylindrical shape because it was made of artificial resin, and the valley extending in the vertical direction toward the center of the lid wall 2 Fold the middle folding line 16 and align the lower side of the folded lid wall 2 with the lower side of the handle wall 1, to form a bag 18 having a tack 17 provided by attaching the lower side of the handle wall 1, The bonding is preferably bonded by welding, and the bonding portion is a bottom bonding portion 19, and the bonding bottom 20 is formed by closing the bottom bonding portion 19, and the bag body 18 is a conventional technique. It is the same structure as the bag part of the plastic bag, and if the tuck 17 is widened, the bonding bottom 20 can be widened and the durable bottom It plays the same role as the wall 3, and the upper part of the handle wall 1 may be wound around the reinforcing tool 11 or may be an empty winding without the reinforcing tool 11, and the through part is formed through the wound belt 21 formed by winding. Although it is desirable to have a structure in which the winding band 21 is fixed by the eyelet 22 that punches the hole 6 and reinforces the edge of the punched hole, the winding state may be fixed by welding and sticking, and the lid 7 is a bag. Folded into a cylindrical shape that opens both sides in the horizontal direction, and the cylindrical shape is formed by folding the tip of the lid 7 with a bag and fixing the folded edge at the base of the lid 7. May be joined by welding and sticking, or may be structured so that it can be partially connected to the winding band 21 and can be fixed in a chain by fixing with the eyelet 22. Both the film 12 and the inner curtain 13 may have the same width.

  FIG. 6 is a perspective view of the closed lid of the main part of the mass production type b through-hole lid type, except that the lid 7 is the same structure as the mass production type a, and the lid hole 23 is punched out as a place where the string 5 is attached. 23 may be one place on each lid 7, but it is desirable to have two symmetrical lines with the center folding line 16 as a center. W shape (shown in FIG. 6) that passes through the other hole and returns to the inside from the other hole, although not shown, it may be either an M shape opposite to the W shape, and is ahead of the lid hole 23 of the lid 7 Since the area can be the tip piece 10, the entire opening of the bag 18 can be closed by pulling up the handle area 8.
