  By the way, all of these patent documents are based on the premise of a state in which some article is accommodated and used, that is, a scene in which the article is taken out. However, in everyday life, it is more frequent to use a bag to take goods from other places than to go with goods. For example, daily commodities can be purchased. Recently, there is a trend to suppress the use of supermarket shopping bags from the viewpoint of environmental protection, and it is often encouraged to bring shopping bags.

  However, when carrying a tightly shaped bag, the bag itself becomes a baggage and is inconvenient. Therefore, in general, cloth bags and bags are often used. In these bags and bags, the storage is certainly compact, but when it is not in use, it is almost always folded in a random manner. The aesthetics are often impaired by wrinkles caused by folding. In addition, depending on how it is stored, the same part may be folded repeatedly with a heavy load, and an excessive load may be applied to one part of the fabric constituting the bag, causing the fabric to be damaged. obtain.

  Or, a furoshiki can be cited as a traditional storage tool, but its use tends to be avoided due to the difficulty in tying it during storage and the troublesome folding during storage.

  Therefore, an object of the present invention is to provide a bag that is compact at the time of storage and aesthetic at the time of use, is easy to deploy and store, and has high durability.

  In order to achieve the above object, the bag according to the present invention is a bag-like member in which a planar material is folded in half, the folded portion is the bottom, a part of the side periphery is sewn, and an opening is provided at the top. A bag having a main body portion and a string-like handle portion whose both end portions are joined to the edge of the opening of the main body portion, and the main body portion is subjected to pleating The pleating process includes a plurality of mountain fold lines and valley fold lines, and two adjacent sides across the wide angle are fold lines in the same direction, and two adjacent sides facing each other are in the opposite direction. A plurality of parallelograms that are fold lines are formed, and each of the plurality of parallelograms is configured to share each side composed of a fold line with an adjacent parallelogram. Item 1).

  According to this device, when folded, it is folded according to each fold line applied by pleating, so that no excessive creases are produced, and the appearance is not impaired even when the folds are unfolded. Further, by appropriately folding, it is possible to prevent the bag from being damaged quickly due to an excessive load on the cloth at a specific portion. On the other hand, a predetermined pattern pattern appears in the main body portion of the bag by pleating, which leads to an improvement in aesthetic appearance. In addition, the crease obtained by pleating has an advantage that the impact on the article contained in the bag can be reduced. Furthermore, deployment during use and storage during non-use can be performed instantaneously.

  Moreover, the pleating process performed on the main body portion of the bag according to the present invention can be configured such that the lengths of the sides other than the side shared with the adjacent parallelogram are different from each other.

  According to this, it is possible to avoid an excessive thickness when folded while maintaining a certain degree of compactness during storage. Moreover, the unevenness | corrugation at the time of use does not become a monotonous pattern, but the beauty | look is improved further.

  Further, the bag according to the present invention is folded along each fold line when stored, and when used, the surface of the main body portion has an uneven shape due to the crease elasticity. 3).

  According to this, the appearance increases in appearance due to the formation of irregularities during use, and the transmission of vibration during walking to the accommodated article is alleviated.

  In addition, the bag according to the present invention is a main body configured as a bag-like member in which a planar material is folded in half, the folded portion is the bottom, a part of the side peripheral edge is sewn, and an opening is provided at the top. A bag having a portion and a string-like handle portion whose both end portions are joined to the edge of the opening of the main body portion, and the main body portion is subjected to Miura fold-like pleating (Claim 4).

  According to this, since unnecessary folds are not generated at the time of storage, it is possible to achieve both compactness at the time of storage and good appearance at the time of use. In addition, it is possible to prevent the cloth of a specific portion from being damaged quickly by being appropriately folded. “Miura folding” is a map folding method devised by Mr. Kosuke Miura (Professor Emeritus at the University of Tokyo), and is also applied to solar panels of space experimental satellites.

  As described above, according to the present invention, the compactness at the time of storage and the aesthetics at the time of use can be achieved, the deployment and the storage can be performed instantly and easily, and a highly durable bag can be provided. In addition, the folding line applied during use has elasticity, so that even if an article of a certain weight is accommodated, it does not fully expand, leaving irregularities on the surface portion of the main body, which makes it more aesthetically pleasing. In addition, the elasticity reduces the transmission of impact to the articles contained in the bag.

  The best mode for carrying out the present invention will be specifically described below with reference to the drawings.

  FIG. 1 is a front view of a bag according to an embodiment of the present invention when stored. The bag 1 has a main body portion 2 and a handle portion 3. Both the main body portion 2 and the handle portion 3 are made of cloth. However, the material is not limited to this, and is a foldable sheet material such as leather or polyester, and can be appropriately employed as long as the effects of the present invention are not impaired.

  The main body portion 2 is configured by folding a single sheet-like material in half and stitching the combined side ends. The bottom part 11 is constituted by the crease, and the side peripheral edge part 12 is constituted by stitching both side ends (illustration of the seam is omitted). Thereby, one sheet-like raw material turns into a bag-shaped member which has the opening part 13 upwards.

  However, the construction method of the bag-shaped member is not limited to the above-described method, and depending on the material, both side ends may be heat-sealed instead of stitching, and part of the peripheral portion of the two planar materials May be combined. In short, it is sufficient that the bag-like member to be completed has a planar shape that can be folded.

  The handle portion 3 is a portion that the user uses as a handle when the bag 1 of the present embodiment is in use. In this embodiment, like the main body portion 2, it is made of a cloth material, and both ends thereof are appropriately joined to the edges of the opening of the main body portion 2.

  FIG. 2 is a diagram showing an end surface taken along line AA in FIG. By the pleating process, the mountain fold line FF and the valley fold line FB viewed from the front direction are arranged alternately in the horizontal direction of the bag 1. Further, there is a difference between the length from the mountain fold portion to the valley fold portion and the length from the valley fold portion to the mountain fold portion. In the present embodiment, the creases are made so as to be approximately 1: 2. Therefore, even when stored, the fabric is not excessively bulky, and the ease of storage is not impaired.

  FIG. 3 is a front view of the bag 1 of the present embodiment in the unfolded state, and FIG. 4 is an enlarged view of the fold of the main body portion 2.

  As described above, the bag 1 according to the present embodiment is formed by stacking planar materials, and is pleated so that a predetermined fold line is generated in the main body portion 2 thereof. FIG. 4 shows the fold line. In the present embodiment, the four regions of the first parallelogram PL1, the second parallelogram PL2, the third parallelogram PL3, and the fourth parallelogram PL4 are two in the vertical direction as shown in the figure. Next, they are adjacent to each other so as to form two “field” characters in the horizontal direction.

  Here, each of the parallelograms adjacent in the vertical direction (the first parallelogram PL1 and the second parallelogram PL2, and the third parallelogram PL3 and the fourth parallelogram PL4) are in the horizontal direction. The lengths of the sides are the same, and the lengths of the sides in the vertical direction are different. On the other hand, each parallelogram (the first parallelogram PL1 and the third parallelogram PL3, and the second parallelogram PL2 and the fourth parallelogram PL4) adjacent in the horizontal direction is in the vertical direction. The side lengths are the same, and the horizontal side lengths are different.

  In each parallelogram, two adjacent sides across the wide angle WA are fold lines in the same direction, and two adjacent sides facing each other are fold lines in the opposite direction. For example, the first parallelogram PL1 is composed of four fold lines VL11, VL21, HL11, and HL21, but VL11 and HL21 adjacent to each other across a wide angle are both mountain fold lines and face each other. Both VL21 and HL11 are valley fold lines.

  The second parallelogram PL2 that is adjacent to the first parallelogram PL1 in the vertical direction is composed of four fold lines VL12, VL22, HL21, and HL31, and the first parallelogram PL1. And share HL21.

  Similarly, the third parallelogram PL3 horizontally adjacent to the first parallelogram PL1 is composed of four folding lines VL21, VL31, HL12, and HL22, and the first parallelogram PL1. And VL21 are shared. The fourth parallelogram PL4 is composed of four folding lines VL22, VL32, HL22, and HL32. The fourth parallelogram PL2 and VL22 are replaced with the third parallelogram PL3 and HL22. Each share.

  Here, the vertical sides VL11, VL21, and VL31 have the same length, and the vertical sides VL12, VL22, and VL32 have the same length. VL11 and VL12, VL21 and VL22, and VL31 and VL32 are configured to be on the same straight line, but the length ratio is configured to be approximately 1: 2.

  On the other hand, the horizontal sides HL11, HL21, and HL31 are naturally the same length, and the horizontal sides HL12, HL22, and HL32 are naturally the same length. Further, HL11 and HL12, HL21 and HL22, and HL31 and HL32 abut at the apex angles of the respective parallelograms, but they are not in the same straight line but are slightly angled. In the present embodiment, it is configured to be inclined up and down by about 15 degrees, but is not limited to this, and can be set as appropriate. The length ratio is approximately 1: 2 (see FIG. 2).

  As a result, the pleating process in which the mountain fold line (single line in FIG. 4) and the valley fold line (double line in FIG. 4) are alternately arranged is performed, and the direction of the arrow DD in FIG. It expands and contracts in the diagonal direction of the constituting rectangle. Therefore, it is folded according to each fold line at the time of storage, and a compact but not bulky shape is realized. In addition, since it is not necessary to fold it when storing it, it is possible to prevent extra wrinkles that are not visually beautiful from occurring in the bag. In use, the bag can be unfolded very simply and instantaneously by pulling in the direction of the arrow D in FIG. 1, and can also be instantly folded along the fold line when stored.

  Even when the article is actually accommodated, the crease formed by the pleating process does not completely unfold and remains as a crease, so that the main body portion 2 itself has elasticity. For this reason, as shown in FIG. 5, since the irregular shape is generated on the surface of the main body portion 2, not only the aesthetic appearance of the bag is improved, but also the effect of reducing the impact from the outside and contributing to the prevention of damage to the article. .

  The embodiment described above is only one form for realizing the present invention, and does not particularly limit the present invention. The effects described in the embodiments of the present invention are merely a list of the most preferable effects resulting from the present invention, and the effects of the present invention are not limited to those described in the embodiments of the present invention. Absent.

It is a front view at the time of expansion | deployment of the bag concerning this invention. It is the elements on larger scale of the main-body part which show the folding line produced by the pleating process given to the bag in this invention. It is a perspective view in the use condition of the bag concerning this invention.
