Utility Model Registration No. 3072938 JP 2002-142831 A

  All of the conventional foldable shopping bags described above can be folded and stored in a compact manner so that they can be conveniently carried in a non-use form, but when set in a plastic basket, the portion that becomes a product input port is large. In order to maintain the open state, an elastic wire material such as a piano wire that performs a bag expanding action is disposed on the central circumferential portion of the bag. For this reason, since the bag itself cannot stand on its own, it has been necessary to prepare a separate empty regi cart at the checkout counter or the transfer counter, and to unfold and hold the shopping bag in the empty regi cart.

  The present invention has been proposed by paying attention to such points, and an object of the present invention is to provide a shopping bag that is compact for carrying in a non-use form but can be self-supporting when in use.

  In order to achieve the above-mentioned object, the present invention described in claim 1 is a shopping bag formed of a thin sheet-like material that is configured to be foldable and deformable, and accommodates a wire having springiness around it. And an elliptical side member in which a sheet material is stretched between the wire members, and an upper surface member having an opening formed by covering an annular wire member having a spring property with a peripheral member. The member and one upper surface member are connected to each other so that they can swing relative to each other at the periphery of the ellipse on the short diameter side, and the same portion as the sheet material is formed on the long diameter side portion between the side surface member and the upper surface member. By forming a film body of the material, a shopping bag body having an opening on the upper surface is formed, and a band for the hander is formed over the front, rear, and bottom surfaces that are composed of side members that are stretched with a sheet-like material. It is characterized by a cloth.

  In addition to the structure of the invention described in claim 1, the present invention described in claim 2 connects a cylindrical net material to the peripheral material portion of the upper surface member, and the free end of the cylindrical net material It is characterized in that a drawstring is arranged in the part.

  In addition to the configuration of the invention described in claim 1 or 2, the present invention described in claim 3 further includes a pocket for accommodating a shopping bag folded from one of the connecting portions of the top member and the side member. The present invention described in claim 4 is characterized in that, in addition to the configuration of the invention described in any one of claims 1 and 3, the sheet material is formed of a waterproof material. It is characterized by.

  In the present invention, not only the upper and lower surfaces but also the front and rear surfaces that connect the upper and lower surfaces accommodate a wire material having springiness around it, and use an elliptical side member that stretches a sheet material between the wire materials. Since the shopping bag body is self-supporting, it is not necessary to prepare a separate regi cart when transferring a product already settled at the check-out counter or the transfer counter from the regi- cart to the shopping bag brought with you.

  Furthermore, a wire rod having a spring property is arranged on the periphery to form the front and rear and upper and lower four surfaces in a basic shape ellipse, and the portion formed by these four surfaces is in a state without a bone frame surrounding the periphery, By superimposing and twisting the four oval surfaces, the three rings can be folded and accommodated in an overlapping state, and can be carried in a compact state.

  In addition, since the bandage for the rider is stretched over the front, rear, and bottom surfaces, which are composed of side members that stretch the sheet-like material, even when a bag is used, heavy objects can be accommodated inside it. Since the weight of the bag can be borne by the hand strap, deformation during use of the bag can be suppressed as much as possible.

  Further, as in the invention described in claim 2, when a cylindrical net member is connected to the peripheral member portion of the upper surface member and a drawstring is disposed at the free end portion of the cylindrical net member, After storing the adjusted product, this cylindrical net material is pulled out and the free end (mouth) is squeezed with a drawstring to cover the upper surface of the stored item, so that the upper surface member is formed. Even if it is accommodated above the opening, the internal contents can be prevented from falling.

  Furthermore, when the pocket which accommodates the shopping bag folded from one connection part of an upper surface member and a side surface member is continued like the invention described in Claim 3, accommodation at the time of carrying in a folded state Even when the bag is unfolded and used, it can always be integrated with the bag body.

FIG. 1 shows an embodiment of the present invention, and FIG. 1 is a perspective view of a shopping bag in an unfolded state.
This shopping bag has an elliptical side member (1) that is stretched by placing a wire material (2) having spring elasticity on the periphery of the sheet material (1) formed in a substantially elliptical shape. 3) and an upper surface member (6) in which an opening (5) having a substantially full opening is formed by covering the wire (2) having spring elasticity with the peripheral material (4). The upper surface member (6) and the three side surface members (3) are connected to each other so as to be able to swing relative to each other at the short-side peripheral portion of the side surface member (3), and the four surface members (6) (3a) ( 3b) A shopping bag body (B) having an opening on the upper surface is formed by stretching a film body (7) of the same material as the sheet material (1) at a position formed on the end surface side of the longer diameter side of (3c). Forming. Then, the upper surface member (6) and the three side surface members (3) are connected to each other at the peripheral portion of the short diameter side of the side surface member (3), so that the upper surface member (6) also forms an oval shape.

  In this shopping bag body (B), a cylindrical net member (8) formed of a mesh material is connected to the peripheral member (4) of the upper surface member (6). A fastening string (9) is inserted and arranged at the leading end portion (free end portion) of the cylindrical net material (8), and the free end of the cylindrical net material (8) is inserted by the fastening string (9). By squeezing the portion, as shown in FIG. 2, the upper surface opening (5) of the shopping bag body (B) is covered.

  In addition, the shopping bag body (B) is provided with a bandage for a bridle (10) formed in an annular shape with a single strap on the outer surface portion of the three side members (3a) (3b) (3c). Between the side member (3a) located on the front side of the two side members (3a) (3c) constituting the vertical wall surface and the upper member (6). A storage pocket (11) for storing the folded shopping bag is connected to the coupling portion in a state of being lowered.

  Front wire member (3a) forming the front surface, bottom surface member (3b) forming the bottom surface, rear surface member (3c) constituting the rear surface, and wire rod (2) having spring elasticity arranged at the peripheral portion of the upper surface member (6) For example, a piano wire, a SK material wire, or a synthetic resin wire can be used. Further, a sheet material (1) stretched at a place formed on the side surface of the long diameter side of each of the side members (3a) (3b) (3c) and the four surface members (6) (3a) (3b) (3c) ) And the film body (7) can be made of a cloth made of chemical fiber such as nylon fiber or a cloth made of natural fiber, more preferably a cloth subjected to waterproofing.

  In the above embodiment, the major and minor dimensions of the side member (3) are formed in accordance with the width and depth dimensions of the bottom surface of the front basket in the bicycle, It is designed to fit inside.

When the shopping bag having the above configuration is not used, the shopping bag is folded in the following procedure and stored in a compact manner.
That is, the string 9 attached to the free end portion of the cylindrical net material 8 is loosened, and the cylindrical net material 8 is stored in a state where it hangs down in the bag body B (FIG. 1). The rear surface member (3c) where the pocket (11) is not arranged and the upper surface member (6) are folded so that the connection portion overlaps the connection portion between the bottom surface member (3b) and the front surface member (3a) (FIG. 3). . As a result, the rear member (3c) and the bottom member (3b), and the top member (6) and the front member (3a) are overlapped.

  Next, the upper surface member (6) and the front surface member (3a) in the overlapped state are further overlapped on the upper side of the overlapping rear surface member (3c) and the bottom surface member (3b). As a result, the four surface members are laminated in four layers to form a single plate (FIG. 4).

  By twisting the surface member in a state where the four sheets overlap with each other in the longitudinal direction (FIG. 5), the three circles are folded flat in a state where the three circles overlap (FIG. 6). ) And stored in the storage pocket (11) (FIG. 7).

  As described above, the shopping bag of the present invention is compactly folded when not in use, and is easy to carry, but when deployed and used, the four bags that constitute the front and rear side surfaces and the upper and lower side surfaces are used. Since the surface members (3a), (3b), (3c), and (6) are connected by the wire (2) having spring elasticity arranged on the periphery thereof, the restoring force of the wire (2) having spring elasticity is Can be easily deployed. And in the unfolded state, since the wire rod (2) having spring elasticity acts as a frame, it has self-sustainability and shape retention, and can easily transfer the settled product from the regi basket. In addition, even if it is placed on the floor or chair of a car, it can stand on its own and keep its shape.

  Further, since the cylindrical net member (8) is continuously provided from the peripheral portion of the upper surface member formed in a substantially front opening shape, when the article is put therein, it acts as an upper surface covering, It is possible to suppress spillage of stored items. Furthermore, by forming the size of the shopping bag into a size that can be stored in the front basket of the bicycle, it can be used for shopping on a bicycle, and at that time, the upper surface portion is covered with the cylindrical net material (8), By tightening the tightening cord (9), when the upper surface opening portion is closed, it becomes a so-called anti-chucking device, thereby preventing crime damage.
