Description

The present invention relates to a drawstring bag used to carry small items, and in particular to a drawstring bag that can be unfolded and used as a mat.

Generally, a drawstring bag used to carry small items has a bag body with an opening, and a drawstring that is inserted around the periphery of the opening with a portion of the drawstring exposed to the outside of the bag body, and is configured so that the opening can be tightened by pulling the drawstring (for example, Patent Document 1).

JP 2005-231681 A

The conventional drawstring bag described above is particularly suitable for carrying lunch boxes, since the contents inside are unlikely to move around too much when the appropriate size is selected according to the size of the contents. However, this type of bag is no longer needed after the lunch box is removed from the bag, so there is a problem that it gets in the way when eating.

In addition, in consideration of the above problems, it is possible to place the bag under the lunch box while eating, but in this case, it is necessary to take the lunch box out of the bag, fold the bag, place it on a table or on your lap, and then place the lunch box back on top of the bag, which makes meal preparation time-consuming. Furthermore, the tightening string extending from the periphery of the opening of the bag gets in the way of eating, and there is also the risk that other objects may get caught in the tightening string, causing the lunch box and its contents to fall.

The present invention was made in consideration of the above problems, and aims to provide a drawstring bag that can also be used as a mat, which is easy to use.

To solve the above problems, the rug/drawstring bag of the present invention incorporates the following technical measures:

The rug/drawstring bag of the present invention comprises a flexible flat sheet body, a hanging string that is attached to the center of the inner surface of the sheet body, extends toward the periphery of the sheet body, and has both ends connected to positions near the periphery, and a pair of string insertion sections that are disposed at opposing positions on the periphery with the hanging string in between. The sheet body is formed into a bag shape by overlapping the two string insertion sections and inserting the hanging string into each of the string insertion sections from the inner surface side.

The string insertion portion may also be connected to the inner surface portion.

The strap may also be formed in a flexible flat band.

The string insertion section may also be formed by bending a flexible flat band into a generally U-shape.

The sheet body may be formed in a generally square shape in a plan view, the hanging string may extend in a first diagonal direction of the sheet body, the two end portions may be connected to positions near corners of the first diagonal direction, and the string insertion portions may be disposed in positions near corners of the second diagonal direction of the sheet body.

The drawstring bag/mat of the present invention has a sheet body in the form of a bag, which makes it easy to carry the contents inside. On the other hand, when the sheet body is unfolded, it becomes a mat as it is, so it does not get in the way when eating. It also does not require much effort to prepare meals, and the carrying strap is unlikely to get in the way while eating. This makes it much easier to use.

The following describes a rug/drawstring bag according to an embodiment of the present invention with reference to the drawings. Note that the embodiment described below is an example of the present invention, and does not limit the configuration of the present invention to this specific example.

As shown in Figures 1 to 3, the drawstring bag/mat 1 of this embodiment is used primarily for carrying food containers P such as lunch boxes, and includes a sheet body 2, a carrying string 3, and a pair of string insertion sections 4. Note that the drawstring bag/mat 1 of this embodiment can be used not only for lunch boxes, but also for carrying various small items that can be packaged in the sheet body 2, such as lidded containers for storing food, plates, cups, beverage bottles, confectionery boxes, cosmetics, stationery, tools, Shinto altar items, funeral equipment, books, etc.

The sheet body 2 is a flexible cloth body that is roughly square in plan view, and is transformed into a roughly pyramidal bag by folding back the four corners 11 toward the center of one of the flat surfaces (inner surface portion) 2A (see Figures 4 to 8).

The sheet body 2 is made of a plain weave fabric of cotton or a plain weave fabric of nylon or polyester synthetic fibers, and has sufficient rigidity to be able to maintain the approximately pyramidal bag shape when it is deformed into a bag shape as described above.

In this embodiment, the outer surface of the sheet body 2 is made of different materials from the inner surface of the sheet body 2A, but the outer surface and the inner surface of the sheet body 2A may be made of the same material. The sheet body 2 may be made of a cloth that has been treated to be water repellent or waterproof, or may be made of natural leather, a synthetic resin sheet such as polyester or polyvinyl chloride, or other material suitable for use as a bag.

The hanging strap 3 is a flexible, flat, band-like cloth body that extends from the center of the inner surface portion 2A of the sheet body 2 toward the peripheral edge portion 2E, and both ends 12 are connected to positions near the peripheral edge portion 2E of the sheet body 2.

More specifically, the hanging string 3 extends in the first diagonal direction (left-right direction in FIG. 1) X1, X2 of the sheet body 2, and both ends 12 are fixed to the corners 11 in the first diagonal direction X1, X2 of the inner surface portion 2A of the sheet body 2 by multiple eyelets 13 (see FIG. 1 and FIG. 2). Note that the ends 12 of the hanging string 3 may be fixed by a single eyelet 13 or may be sewn with thread, as long as they are firmly fixed to the sheet body 2.

When the sheet body 2 is laid out flat, the strap 3 is arranged flush along the inner surface 2A of the sheet body 2. This prevents unnecessary irregularities from being formed on the inner surface 2A of the sheet body 2.

The carrying strap 3 is made of the same material as the sheet body 2, and has enough rigidity to be held in a looped, standing state (see Figures 6 to 8) at the butted corners 11 when the strap is curved and inserted through the strap insertion section 4. This makes it easy for the user to hold the carrying strap 3 in their hand when carrying the rug/drawstring bag 1.

The food container P, which is the contents, is placed in the gap between the inner surface portion 2A of the sheet body 2 and the hanging strap 3 (see FIG. 1). As a result, the food container P is held by being lightly pressed against the sheet body 2 by the hanging strap 3. In other words, the hanging strap 3 is configured to lightly hold the food container P so that it does not slip when the sheet body 2 is in an unfolded state. The hanging strap 3 may be made of a fabric or material different from that of the sheet body 2, or may be made of various fabrics or materials like the sheet body 2.

The string insertion section 4 is made of a flexible flat belt-shaped cloth body, and is provided at a position facing the hanging string 3 on the peripheral portion 2E of the sheet body 2. In detail, the string insertion section 4 is formed into a loop by folding a flexible flat belt-shaped cloth body into an approximately U-shape and fixing both end portions 14 to the corner portions 11 in the second diagonal direction (the up-down direction in FIG. 1) Y1 and Y2 on the inner surface portion 2A of the sheet body 2 with multiple eyelets 15 (see FIG. 1 and FIG. 2). Note that the end portion 14 of the string insertion section 4 may be fixed by a single eyelet 15 or sewn with thread, as long as it is firmly fixed to the sheet body 2.

The string insertion section 4 is made of the same material as the carrying strap 3, and has a degree of rigidity that prevents the carrying strap 3 from easily slipping out when it is inserted through the string insertion section 4. This allows the sheet body 2 to maintain its roughly quadrangular pyramid shape even if the user releases the carrying strap 3. The string insertion section 4 may be made of a different material or fabric than the carrying strap 3, or, like the sheet body 2, may be made of various material or fabrics.

As shown in FIG. 1, the string insertion section 4 is fixed to the corner 11 of the sheet body 2 with the band-shaped ends 14 aligned parallel to each other. This defines a narrow slit-shaped opening 4H on the inside of the string insertion section 4 that extends in the second diagonal directions Y1 and Y2, i.e., in a direction perpendicular to the extension direction of the hanging strap 3.

The hanging cord 3 is inserted through the opening 4H of the cord insertion section 4 while bent into a loop shape, and at this time, the long edge 16 of the opening 4H of the cord insertion section 4 abuts against the outer surface 3B of the hanging cord 3 (the flat surface opposite the inner surface 2A of the sheet body 2) from the first diagonal directions X1 and X2. This holds the hanging cord 3 in the cord insertion section 4 so that it does not easily slip out.

When a food container P is stored and carried, first, as shown in Fig. 1, the sheet body 2 is unfolded and the food container P is placed in the gap between the inner side surface portion 2A of the sheet body 2 and the hanging string 3. Next, as shown in Fig. 4, the corners 11 of the sheet body 2 in the second diagonal directions Y1 and Y2 are folded back to the center of the inner side surface portion 2A, and the two string insertion portions 4 are overlapped. Then, while bending the middle portion of the hanging string 3, it is inserted into the openings 4H of the two string insertion portions 4 from the inner side surface portion 2A side of the sheet body 2 and pulled up, and in conjunction with this, the corners 11 of the sheet body 2 in the first diagonal directions X1 and X2 are folded back to the center of the inner side surface portion 2A. As a result, the food container P is packaged by the sheet body 2, and the rug/drawstring bag 1 becomes a portable drawstring bag, as shown in Figs. 5 to 8.

On the other hand, when removing a food container P from the drawstring bag 1 in this form, the carrying string 3 is removed from the opening 4H of the string insertion section 4, and the four corners 11 that were folded back toward the center of the inner surface section 2A of the sheet body 2 are spread outward in the diagonal directions X1, X2, Y1, and Y2. As a result, the sheet body 2 is laid out flat as shown in FIG. 1, and can be used as a cover for the food container P as is.

In this way, the rug/drawstring bag 1 of this embodiment comprises a flexible sheet body 2, a hanging string 3 that extends from the center of the inner surface portion 2A of the sheet body 2 toward the peripheral edge portion 2E of the sheet body 2 with both ends 12 connected to positions near the peripheral edge portion 2E, and a pair of string insertion portions 4 that are disposed at opposing positions on the peripheral edge portion 2E, sandwiching the hanging string 3 therebetween. By overlapping the two string insertion portions 4 and inserting the hanging string 3 into each of the string insertion portions 4 from the inner surface portion 2A side, the sheet body 2 is formed into a bag shape.

With this device, a food container P is placed on the inner surface 2A of the sheet body 2, and a pair of string insertion sections 4 provided on the peripheral portion 2E (corner portion 11) of the sheet body 2 are overlapped with each other, and a carrying string 3 is inserted into the string insertion sections 4 from the inner surface 2A side of the sheet body 2, so that the sheet body 2 becomes a bag, making it easy to carry the food container P. On the other hand, if the carrying string 3 is removed from the string insertion section 4 and the sheet body 2 is unfolded, it becomes a cover for the food container P, so it does not get in the way when eating and does not require much effort to prepare a meal. In addition, since the carrying string 3 is arranged along the inner surface 2A of the sheet body 2, it is unlikely to get in the way when eating. This significantly improves usability.

The string insertion section 4 is connected to the inner surface section 2A. In this way, the string insertion section 4 is provided on the same plane as the carrying strap 3, so that the carrying strap 3 can be easily inserted into the string insertion section 4 even when the sheet body 2 is in an unfolded state, further reducing the effort required to transform the sheet body 2 into a bag shape. This further improves usability.

The carrying strap 3 is also formed in a flexible flat band shape. This allows the sheet body 2 to have fewer projections and recesses on the inner surface portion 2A of the sheet body 2 when it is unfolded, so the food container P can be placed more stably on the sheet body 2. This further improves usability.

The string insertion section 4 is formed by bending a flexible flat band into a roughly U-shape. This increases the engagement resistance between the carrying string 3 and the string insertion section 4 when the carrying string 3 is inserted, so the carrying string 3 can be more reliably held in place by the string insertion section 4. This makes it difficult for the shape of the drawstring bag to collapse even if the user lets go of the carrying string 3, further improving usability.

The sheet body 2 is formed in a generally square shape when viewed from above, the hanging strap 3 extends in the first diagonal directions X1 and X2 of the sheet body 2, and both ends 12 are connected to positions near the corners 11 of the first diagonal directions X1 and X2, respectively, and the strap insertion portions 4 are disposed near the corners 11 of the second diagonal directions Y1 and Y2 of the sheet body 2, respectively.

In this case, the corners 11 of the sheet body 2 in the second diagonal directions Y1 and Y2 are folded back toward the center of the inner surface portion 2A, the two string insertion sections 4 are overlapped, and the middle section of the hanging string 3 is inserted through the openings 4H of the two string insertion sections 4 from the inner surface portion 2A side of the sheet body 2. When the sheet body 2 is pulled up, the food container P is stored inside the sheet body 2, and the sheet body 2 takes the form of a drawstring bag, which further improves usability.

In this embodiment, the sheet body 2 is formed in a substantially square shape, but as long as the entire food container P can be appropriately wrapped when made into a drawstring bag, it may be formed in a substantially rectangular shape when viewed from above, or in an irregular shape such as a polygonal shape with more than a square when viewed from above, a substantially circular shape, a flower shape, a star shape, or the like.

In addition, in this embodiment, the hanging strap 3 is formed in a flat band shape, but as long as usability is not impaired, the hanging strap 3 may be formed from a flat string or a round string. In addition, the hanging strap 3 may be connected to the outer surface portion 2B of the sheet body 2, or may be connected to the peripheral portion 2E of the sheet body 2.

In this embodiment, the string insertion section 4 is connected to the inner surface 2A of the sheet body 2, but it may be connected to the outer surface 2B of the sheet body 2 or to the peripheral portion 2E of the sheet body 2 as long as usability is not impaired. The string insertion section 4 may be a circular or slit-shaped through-hole provided near the peripheral portion 2E of the sheet body 2, or may be a loop-shaped ear piece formed integrally with the peripheral portion 2E of the sheet body 2. Alternatively, it may be formed from a generally U-shaped or annular metal member, synthetic resin member, or the like having low flexibility and connected to the peripheral portion 2E of the sheet body 2.
