Description

  The present invention relates to a foldable envelope made of a sheet material, and more particularly to an envelope that can be folded and carried in a predetermined form that is reduced in volume by a simple pulling operation. The enclosure includes a body cover that covers an automobile or a bicycle, a handle cover that covers an automobile handle, and a rain cover that covers a saddle of the bike. The envelope further includes a handbag, a pouch, a shoulder bag, and a waist bag.

  Various proposals have been made for folding a foldable article made of sheet material into a small promised form, that is, reducing the volume of the article. A conventional example will be described taking a typical handbag as an example. Patent Document 1 proposes volume reduction of a packaging handbag. This packaging bag has a bellows structure. That is, the handbag of Patent Document 1 has a bellows structure in which mountain folds and valley folds are alternately continued in the vertical direction from the bottom to the bag opening. By storing the products in a bag so as to be stacked, it becomes a handbag for packaging with the bellows structure extending upward.

  Patent Document 2 proposes a portable bag having a bellows structure. Patent Document 2 discloses two types of modes. The first type has a structure in which mountain folds and valley folds are alternately continued in the vertical direction from the bottom to the upper end. The second type has a structure in which mountain folds and valley folds are alternately continued in the lateral direction.

  Patent Document 3 proposes a foldable handbag suitable for an eco bag. This handbag has a bag body having a rectangular shape such as a square or a rectangle when viewed from the front, and a pair of left and right handbags extending upward from the left and right upper ends thereof. The bag body has gussets on the left and right side walls. Folds extending in the vertical direction are provided on the front and back surfaces of the bag body, respectively. In each of the front surface and the back surface, two fold lines are provided, and the two fold lines are separated from each other on the left and right.

  In order to fold the handbag to reduce the volume, first, the used handbag is spread flat on a flat table, and then the bag body is folded along the crease. As a result, the handbag has a predetermined band shape. Next, the belt-like handbag is folded into four and folded into a small rectangular shape. Alternatively, a belt-like handbag is wound from one end to form a roll shape.

  Patent Document 4 proposes a folding bag that is convenient for use when taking a dung while walking a dog, taking a leftover food, and the like. This folding bag has a tunnel extending in the lateral direction at a bag opening having a rectangular shape when viewed from the front, and two ring-shaped straps are inserted through the tunnel. The first strap is exposed to the outside from one end of the tunnel. The second strap is exposed to the outside from the other end of the tunnel. The bag opening can be closed by pulling the first and second straps.

  The folding bag has two vertical folds extending from left to right and seven horizontal folds extending in the horizontal direction. Seven horizontal fold lines are arranged at equal intervals from the lower end of the folding bag. The folding bag is folded along the left and right vertical folds to form a first folded shape in the form of a band. The band-shaped first folded bag is then folded along seven transverse folds into a small rectangular final folded configuration. Then, the final folded bag is inserted into the outer bag.

  It is convenient to use the folding bag of Patent Document 4 mainly as a disposable bag. In other words, a troublesome operation is required to fold a used bag for reuse.

  Disposable so-called plastic bags (polybags) made of polyolefin and other materials are used in large quantities at retail stores such as supermarkets. From the viewpoint of environmental issues, it is recommended to bring shopping bags instead of plastic bags. Shopping bags are called “eco bags”. The eco bag is desired to be in a small form when it is carried. Therefore, it is desired that the eco bag after use is in a small and predetermined promised form, that is, a reduced volume form by a simple folding operation. And it is desirable that the small form, that is, the reduced form, should have a good appearance.

  The object of the present invention is to allow the enclosure opening for taking in and out the article to be made smaller after the article is enclosed in the expanded use form, and to be folded into a predetermined form reduced in volume from the use form. An object is to provide an easily foldable enclosure.

According to the present invention, the above technical problem is
First and second tunnel portions that extend in a straight line and are positioned on one side and the other side of the enclosure opening for taking in and out the object, and extend along the enclosure opening;
A first strap that is inserted through the first tunnel portion and can reduce the enclosure opening;
A second strap that is inserted through the second tunnel portion and can reduce the enclosure opening;
An enclosure body surrounding an object received through the enclosure opening;
A plurality of pleats formed on the enclosure body, the plurality of pleats closed in a state where both ends of the pleats are stacked,
The enclosure opening can be made smaller by pulling out part of the first and second straps from at least one of the first and second tunnel portions or the central portion. This is accomplished by providing an enclosure.

  As an application example of the present invention, in addition to the above-described eco bag, a portable device that prevents the saddle from getting wet in the rain by covering the saddle of a bicycle in a deployed bag-like state can be exemplified. Further, portable devices that take time to fold, such as tents, rain wings, and ponchos, and covers that cover automobiles or bicycles can also be cited as application examples of the present invention. Furthermore, a seat cover that covers an automobile seat can also be cited as an application example of the present invention. Among outdoor cars (typically SUVs), there are cars that use a water-repellent material for the skin of the seat. When going to a place where such a water-repellent sheet is not easily mounted in an automobile, it is convenient to have a water-repellent and / or waterproof sheet cover. In addition, in a drive accompanied by a pet such as a dog or a cat, it is difficult to remove the hair loss of the dog or cat on the sheet. It would be advantageous if the seat cover could be put on the seat when accompanied by a pet and the seat cover could be removed when the drive was finished.

  Further, the present invention can also be suitably applied to a heat-insulating handle cover that protects the handle from solar radiation, a folding sunshade cover that surrounds an instrument, for example.

  Further objects and advantages of the present invention will become apparent from the following detailed description of the preferred embodiments of the present invention.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, taking an eco bag as a typical application example of the present invention as an example.

First Example (FIGS. 1 to 16) :
Reference numeral 100 indicates an eco bag of the first embodiment, that is, a folding handbag. FIG. 1 shows a form when the handbag 100 is in use. 2 to 5 show changes in the shape of the handbag 100 in time series. FIG. 2 shows a state in which a product purchased in this shop is stored in a handbag 100 inside the shop. FIG. 3 shows a state in which the bag opening 100a of the handbag 100 is widened. In this state, the purchased product can be put in a bag. Moreover, the goods accommodated in this state can be taken out from the handbag 100. FIG. 4 shows a state in the middle of pulling the handbag 100 after use to change it into a belt-like form (described in detail later). FIG. 5 is a front view of the handbag 100 that has been changed to a strip shape.

  Reference numerals 2 and 4 denote two end portions of the handbag 100 facing each other in the form of a belt. The band-shaped handbag 100 has an elongated shape with a longitudinal axis Ax extending from one end 2 to the other end 4 (FIG. 5). After using the handbag 100, the user grips the one end 2 with one hand, grips the other end 4 with the other hand, and pulls the one end 2 and the other end 4 away from each other. The handbag 100 (FIG. 3) in which the bag opening 100a is widened in the width direction only by this simple pulling operation is instantly shown in FIG. 5 through the form shown in FIG. become.

  6 to 8 are side views of the handbag 100 in an unfolded state. FIG. 6 shows a form in which the handbag 100 is developed and the bag opening 100a is greatly expanded in the width direction. FIG. 6 corresponds to FIG. The purchased product can be put in a bag in the form shown in FIGS. When the product has been put in, the first and second strap connecting portions 6 and 8 located opposite to each other across the bag opening 100a (FIG. 1) of the handbag 100 are pulled to reduce the bag opening 100a and Lift up (FIGS. 2 and 7). That is, as shown in FIGS. 1 and 8, an object can be carried using the handbag 100 in a state where the bag opening 100a is narrowed down. FIG. 8 corresponds to FIG.

  FIGS. 9-14 is detail drawing of the handbag 100 of 1st Example when it is set as a strip | belt shape. FIG. 9 is a front view. FIG. 10 is a plan view. FIG. 11 is a bottom view. FIG. 12 is a rear view. FIG. 13 is a right side view. FIG. 14 is a left side view.

  As best seen in FIG. 9, the handbag 100 in the form of a strip has an elongated rectangular shape. In the handbag 100, the first strap connecting portion 6 extends from one end in the longitudinal direction, and the second strap connecting portion 8 extends from the other end. In the handbag 100, this belt-like form is the basic form. The belt-shaped handbag 100 is unfolded (FIGS. 3 and 6), an object is put into the handbag 100, and then the two strap connecting portions 6 and 8 are pulled to reduce the bag opening 100a, thereby reducing the handbag 100. Is lifted (FIG. 1). The handbag 100 can be carried with the bag opening 100a small. After use, the handbag 100 can be changed into a belt-like form by pulling the one end 2 and the other end 4 of the handbag 100 in a direction to separate them from each other. After that, the band-shaped handbag 100 is folded in the longitudinal direction, for example, so that it becomes a small and volume-reduced form convenient for carrying (FIG. 16). This reduced volume will be described later.

  FIG. 15 is a view for explaining a process for manufacturing the handbag 100. In order to make the handbag 100, first, a rectangular fabric 10 made of a square or a rectangle is prepared. The center line CL of the dough 10 is the axis Ax of the above-described band-shaped handbag 100 (FIGS. 5 and 9).

  FIG. 15I shows the first step. In the first step, the pleats 12 are formed in the left and right regions with the center line CL of the fabric 10 in between. When the first step is finished, the fabric 10 has a strip shape having a plurality of pleats 12 formed by folding the one half 10a and the other half 10b across the center line CL. A bag opening 100a is formed at the boundary between the one half 10a and the other half 10b.

  As a preferred embodiment, the first fold line 12a of the plurality of mountain folds 12a and the second fold line 12b of the plurality of valley folds of the pleat 12 are preferably symmetrical with respect to the first half 10a and the second half 10b.

  In the embodiment, the fabric 10 is made of a sheet material made of nylon, but is not limited thereto. Materials such as polyester, cotton, non-woven fabric, vinyl, etc., laminated materials in which synthetic resin is laminated, materials in which synthetic resin and fabric or paper are laminated, leather, materials with a cold insulation function in which aluminum vapor-deposited film is laminated on polyester fabric, etc. If it is a sheet of the nature, it is employable. Further, the fabric 10 may be formed by sewing or bonding a plurality of materials having different colors and materials.

  Preferably, the first fold line 12a and the second fold line 12b are parallel to the center line CL and straight. Further, the number of rectangular folds 14 constituting the pleats 12 on the one half 10a and the number of rectangular folds 14 constituting the pleats 12 on the other half 10b are preferably the same. As a modified example, as will be described later with reference to FIGS. 22 and 23, the mountain fold fold, that is, the first fold 12 a positioned outside the handbag 100 when the belt is formed may be non-linear. .

  The band-shaped handbag 100 has a bag opening 100 a extending from one end 2 in the longitudinal direction to the other end 4. The width W (FIG. 15 (II)) of each fold 14 of the pleat 12 belonging to the one-side half 10a and the other-side half 10b of the handbag 100 is preferably the same. In the following description, for convenience of explanation, one side is called “left” and the other side is called “right”.

  FIG. 15 (II) shows the second step. In the second step, one end and the other end of the strip-shaped dough 10 are closed. In this embodiment, an end closing tape 20 such as a polypropylene tape or a cotton tape is wound around both ends of the belt-shaped fabric 10 and is sewn to close each end of the belt-shaped fabric 10.

  FIG. 15 (III) shows the third step. In the third step, the first and second hand straps ST (1) and ST (2) are attached. In the embodiment, the first and second hand straps ST (1) and ST (2) are connected by the first and second strap connecting portions 6 and 8 at both ends thereof to form a single ring shape. Consists of straps. A ring-shaped strap may be moved in a first tunnel portion 18a and a second tunnel portion 18b, which will be described later, without sewing a ring-shaped strap to the fabric 10. As a preferred embodiment, reference numeral 100b shown in FIG. 15 (III) substantially indicates a fixing portion of one ring-shaped strap ST (1), ST (2). In this embodiment, the fixing portion 100b is constituted by a patch and a seam, but it may be constituted only by a seam. The fixing part 100b is preferably arranged in the middle part in the longitudinal direction. As the first and second hand straps ST (1) and ST (2), a tape made of any material such as polypropylene tape and cotton tape can be adopted. Of course, the first and second strap connecting portions 6 and 8 exposed to the outside may be constituted by independent straps. In this case, the two end portions of each of the two independent straps may be fixed to the middle portion in the longitudinal direction of the handbag 100 in the form of a band.

  Between the uppermost left flap 16a-1 and the lower left flap 16a-2 of the lower half 10a of the left half 10a of the strip-shaped fabric 10, and the uppermost right flap 16b-1 and the lower portion of the right half 10b. Ring-shaped straps ST (1) and ST (2) are inserted between the right flap 16b-2 ((I) and (III) in FIG. 15). Next, the edge of the uppermost left flap 16a-1 of the left half is sewn to the lower left flap 16a-2, and the edge of the uppermost right flap 16b-1 of the right half is Sew on the right flap 16b-2.

  As a result, the first tunnel portion 18a is formed between the edge of the uppermost left flap 16a-1 in the left half and the lower left flap 16a-2, and the uppermost right flap in the right half. A second tunnel portion 18b is formed between the edge of 16b-1 and the lower right flap 16b-2. Further, a single ring-shaped strap ST (1), ST (2), 6, 8 is disposed in a state of being inserted through the first tunnel portion 18a and the second tunnel portion 18b, and the first and second straps are arranged. First and second straps ST (1) and ST (2) passing through the tunnel portions 18a and 18b are sewn and fixed to the longitudinal intermediate portions of the first and second tunnel portions 18a and 18b. (Fixing part 100b).

  In the example shown in the figure, the upper left and right flaps 16a-1 and 16b-1 are positioned on the inner sides and opposed to each other. , 16b-1 may be located outside.

  The handbag 100 has first and second tunnel portions 18a and 18b that are located across the bag opening 100a through the steps (I) to (III) described above, and each of the tunnel portions 18a, A bag body B (FIG. 15 (I)) is configured by sewing, or closing, both ends of the plurality of pleats 12 positioned below 18b. When an object is accommodated in the bag body B, the pleats 12 are expanded, whereby the volume of the bag body B is expanded. Then, first and second straps ST (1) and ST (2) are inserted into the first and second tunnel portions 18a and 18b, and the first and second strap connection portions 6 and 8 are lifted. This reduces the bag opening 100a.

  The handbag 100 of the embodiment preferably includes a relatively large flap 24 at the other end 4, but the flap 24 is not necessarily essential. Referring to FIG. 15 (II), the flap 24 is sewn to one end of the fabric 10 when both ends of the strip-shaped fabric 10 are closed. The flap 24 is used to fix the belt-like handbag 100 in a reduced volume form. Referring to FIG. 15 (II), the flap 24 is sewn to the other end portion 4 of the fabric 10 when both ends of the strip-shaped fabric 10 are closed.

  As will be described later, the flap 24 can exhibit a cover function that surrounds the reduced handbag 100 after the belt-shaped handbag 100 is reduced in volume or after being folded in the longitudinal direction. It preferably has a length dimension.

  FIG. 16 is a view for explaining a process of reducing the volume of the handbag 100 in a band shape. In order to make the belt-shaped handbag 100 into a small volume-reduced form convenient for carrying, first, the belt-shaped handbag 100 (FIG. 9) is folded in the longitudinal direction ((I) of FIG. 16), This is further folded in two (FIG. 16 (II)) and fixed with a flap 24. A button fastener 26A is sewn to the end of the flap 24. A receiving fastener 26B cooperating with the button fastener 26A is sewn to the back surface of the other end 4 of the handbag 100 (FIG. 12). Instead of the fastener 26, a surface fastener may be used. By fixing with the fastener 26 of the flap 24, the handbag 100 in the form of a band is fixed in a predetermined small form with a reduced volume.

  Further, the flap 24 may be omitted, and the handbag bag 100 having a reduced volume may be accommodated in an outer bag, that is, a cover bag. Further, the handbag bag 100 in the form of a belt may be wound, for example, from one end to the other end to reduce the volume, and this may be accommodated in an exterior bag.

  Reference numeral 100b seen in FIG. 2, FIG. 3, FIG. 8, and the like indicates a fixing portion of the first and second straps ST (1) and ST (2). As described above, the first and second hand straps ST (1) and ST (2) are fixed to the tunnel portions 18a and 18b at the intermediate portion in the longitudinal direction of the belt-shaped hand bag 100. As a modification, the first and second hand straps ST (1) and ST (2) may be formed of a single continuous ring-shaped strap.

  17 to 21 show an example in which means for improving the convenience of the developed handbag 100 is provided in the handbag 100. In FIGS. 17 to 21, the first and second hand straps ST (1) and ST (2) are not shown. FIG. 17 shows an example in which the hook-and-loop fastener 28 is disposed at the center portion in the longitudinal direction of the belt-shaped handbag 100. According to the example of FIG. 17, the handbag bag 100 can be fixed to the saddle by covering the developed handbag 100 on, for example, a bicycle saddle and fixing the openings of the handbag bag 100 to each other using the hook-and-loop fastener 28. . Also, the hook-and-loop fastener 28 can be used to close the bag opening of the handbag 100 containing the contents.

  FIG. 18 shows an example in which a relatively small rectangular flap 30 is provided at each of the longitudinal ends of the belt-shaped handbag 100 and a button fastener 32 is disposed on the flap 30. Instead of the button fastener 32, a hook-and-loop fastener may be used. According to the example of FIG. 18, after the purchased product is put in the handbag 100, the left and right flaps 30 are integrated by the button fastener 32, so that a ring can be formed at the upper end portion of the handbag 100. With this ring, the handbag 100 in use can be locked to a hook in an automobile, for example.

  FIG. 19 shows an example in which two D can hooks 34 are provided at a central portion in the longitudinal direction of the belt-like handbag 100 at an interval. FIG. 20 shows an example in which suction cups 36 are provided at both ends in the longitudinal direction of the belt-shaped handbag 100. FIG. 21 shows an example in which S can hooks 38 are provided at both ends in the longitudinal direction of the belt-shaped handbag 100. 19 to 21, the handbag 100 in an unfolded state can be fixed by being hooked on any convenient article or part (for example, a hook inside an automobile).

  The handbag 100 described with reference to FIGS. 1 to 21 is configured by a straight line having both side edges in the longitudinal direction parallel to the axis Ax when the bag is formed in a band shape. The outline of the side edge of the handbag 100 is not limited to a straight line.
