Abstract

PROBLEM TO BE SOLVED: To make it possible to expand and contract freely and change in shape and capacity of a bag-form by cutting open the bag-form of one's liking, and pleating at the opened places where a clasp is installed. SOLUTION: A pleating 1 is performed on the left and right of a bag-form main body 8 through the front, bottom and rear surfaces of a bag-form 10; that is, the boundary lines of the front, bottom and rear surfaces are cut opened, the cut surfaces are moved to the left and right parallel with each other, and the opened places are pleated 1 where three kinds of clasps are installed. At the time of installation, after a fastener 2 is attached through the front, bottom and rear surfaces, a tape 4 equipped with a protruded button is suspended from the upper part of one pleated area in contact with the inside of the bag- form main body 8 and a recessed button 3 is installed at both upper ends of both side surfaces 7 of the outside of the bag-form. At the outside of the bag- form, a tape with a button hole 6 on the left and right lower parts of the front and rear surfaces and small metal fittings 5 on the left and right lower parts of the side surface, are installed. When the clasp is removed and the pleat 1 is stretched as far as it goes, the maximum capacity can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag for expanding and contracting a pleated bag to change its shape and capacity, and to a method of manufacturing the bag.

[0002]

2. Description of the Related Art Conventionally, there has been a pleat whose surface is pleated to a degree of decoration, but it has not been intended to change the capacity. In addition, there was a cloth that was opened inside the bag and opened with a zipper to expand the capacity, but this was not pleats, but far from beauty. Thus, one bag was fixed in shape and volume.

[0003]

This has the following disadvantages. I. The fact that the size of the bag is fixed means that there is no flexibility, and that the practicality is low. B. A fixed shape means that it is of little use, even in attire. C. For this reason, the use value of one bag is low, and a large number of bags are required to use it according to time, place, and purpose. The present invention has been made to solve these disadvantages.

[0004]

[Means for Solving the Problems]

I. A bag of an arbitrary shape is cut open, pleats are applied to the opened portion, and a stopper is attached to the pleat. B. A surface corresponding to the direction of expansion and contraction of the bag of an arbitrary shape is cut open from a boundary line with another surface, pleats are applied to the opened portions, and a stopper is attached to the pleats. C. Of the surfaces corresponding to the expansion and contraction direction of the bag of any shape,
Leave one side open and cut the other side from the boundary line, pleat the open area, and attach a stop at the pleat area. D. An arbitrary portion on the surface of the bag having an arbitrary shape is cut open, the entire bag is cut, and the cut portion is pleated, and a stopper is attached to the pleated portion. E. While leaving one side of the bag of an arbitrary shape, all other surfaces or an arbitrary portion of a specific surface are cut open, pleated at the opened portion, and a stop is attached to the pleated portion. F. There are two cases of pleats applied to bags according to the present invention. First, it is a normal pleat made by folding one piece of material. Then, if normal pleats are not possible,
This is a case where pleats are created by joining the cut materials. G. From the above, as a specific example in the case of (b), both sides of the rectangular parallelepiped bag (10) are completely cut open from the boundary with other surfaces, and pleats (1) are applied to the opened portions, and The case where three types of stoppers are attached to the location is shown. That is, a button (3) is provided on the upper part of the pleat, a small metal fitting (5) is provided on the lower part of the pleat, and a fastener (2) is provided on the entire pleat.

FIG. 21, FIG. 22, FIG. 23 and FIG.
An application example of the present invention will be described with reference to FIGS. This is a bag (50) having an upper part in a drawstring shape and a lower part changing from a cylindrical type to a bucket type. First, leaving only the bottom surface, only four curved portions of the lower cylindrical portion (48) are cut open vertically. The pleats (43) and (4) facing each other in a double-folded manner as shown in FIG.
5) is performed. A button (4) is provided on the inner pleats (43) as a stopper to be attached to the pleats.
4) Fasteners (46) were used for the outer pleats (45). Next, as for the upper drawstring portion (49), even if the upper circumference of the lower cylindrical portion (48) is opened in a bucket shape, the drawstring is provided with enough space to cope with it. Pouches (43) and (45) are provided on the lower part and have a bag-like shape (50) that changes from a cylindrical shape to a bucket shape. FIG. 21 shows the outer pleats (45) with the fasteners (46) open and the inner pleats (43) with the buttons (44) removed, with the top circumference of the bucket-shaped portion (48) being the widest and the capacity Is the largest. FIG. 24 is a partial view of the upper part of the pleat. In FIG. 22, the fastener (46) of the outer pleat (45) is opened, and only the button (44) of the inner pleat (43) is used. Cylindrical part (4
The upper circumference of 8) has a slightly open bucket shape, and the capacity is as shown in FIG. FIG. 25 is a partial view of the upper part of the pleat. FIG. 23 shows the case where both the button (44) and the fastener (46) are used. The pleats all shrink, so that the circumference of the bucket-shaped portion (48) also shrinks to a cylindrical shape (48) with a minimum capacity. FIG.
Is a partial view of the upper part of the pleat. As described above, when the double pleats (43) and (45) and the two kinds of stoppers (44) and (46) are to be expanded and contracted twice, the bag (5)
0) indicates three shapes, the capacity of which changes accordingly, and can be used as needed.

Hereinafter, a method of manufacturing a pleated bag, including examples and application examples, will be described. Pleating bags can be done on many bags,
What is necessary is just to implement by a suitable method according to the shape of each bag. That is, open the bag, pleat it,
The most suitable method is to use a stop at the pleat. I. Method of cutting and opening a bag (a) A method of cutting and cutting an entire surface of a bag from a boundary line with another surface. An arbitrary surface of the bag is completely cut out from a boundary line with another surface, and the opened portion is pleated. At this time,
The locus of the movement of the outer shape line of an arbitrary surface corresponding to the expansion / contraction direction is a portion of the surface to which pleats can be applied. FIG. 27 illustrates this concept and the way of opening as a representative example. This shows a case where the left and right vertical sides are cut off from the boundary line and cut off in parallel. If a pleat consisting of parallel lines is applied to this open portion, the bag will expand and contract in parallel to the left and right. The embodiment of FIG. 27 is the bag of FIG. (B) A method that leaves one side of the boundary between the surfaces of the bag and cuts out the other. An arbitrary surface corresponding to the direction of expansion and contraction of the bag is left open, leaving one side of a boundary line with another surface. However, even if the surface to be cut out is not the entire surface depending on the design, it is sufficient to leave one side of the cut-out portion and cut out the other. The remaining one side is assumed to be an axis, and if it is referred to as a hypothetical axis (51), the hypothetical axis (51) is usually one side such as an upper side, a lower side, a left side, and a right side of a surface corresponding to the expansion and contraction direction. The surface opens around the hypothetical axis (51), and the locus of the outline of the surface has moved is where new pleats can be applied. FIG. 28 illustrates this concept and the manner of opening as a representative example. This is a cube
The lower sides of the left and right sides are assumed to be assumed axes, and the upper side is opened outward. That is, the hypothetical axes are two places of DC and HG,
With this as an axis, the left and right surfaces open outward. This means that, from the front, an arc having a radius of CB around C is drawn and an arc of GF having a radius GF around G. From the back side, an arc having a radius of DA around D is drawn, and an arc having a radius of HE around H is drawn. The location thus opened is the location on the surface where new pleats can be applied. That is, the original surface ABCD and the open surface A'B'C
The new possible faces created during D are BCB ',
ADA 'and ABB'A. Original face EF
New possible face locations between GH and open face E'F'GH are FGF ', EHE', EFF'E '
Three places. Therefore, it is conceivable to apply pleats to the surface and to apply pleats to the surface. An embodiment in which pleats (19) are applied to the side and the side surface (22) is opened to a horizontal state is the bag (26) shown in FIGS. (C) A method in which the surface of the bag is cut open and the entire bag is cut. As a representative example showing this concept and the way of opening, a case where the cylindrical mold is cut horizontally is shown in FIG. If this is pleated with parallel lines, it will expand and contract vertically. This embodiment is similar to the bag (4) shown in FIGS.
2). The bag is cut vertically in the vertical direction to form a rucksack (34) shown in FIGS. 17 and 18.
Pleating (27) consisting of parallel lines is applied, and expands and contracts horizontally back and forth. (D) A method in which one side of the bag is left open and all other sides or an arbitrary portion of a specific side are cut open. As a representative example showing this concept and the way of cutting, a case is shown in FIG. 30 in which a curved bottom portion is cut vertically while leaving a cylindrical bottom surface. By pleating the cut-out portion, the circumference of the upper portion of the cylindrical shape is widened, and the shape changes into a bucket shape. This embodiment is shown in FIG. 21, FIG. 22, and FIG. B. Method of making pleats For ordinary pleats, the cases of FIGS. 1, 15, and 21 are possible. There are two cases for pleats to be created. (A) First, the method of making pleats in the case where the cross section of the cut pleats in the bag does not change is as follows. The cross section and the outer shape of the portion cut open so as to face the expansion and contraction direction are congruent, and the inner line is usually cut out of a mold composed of parallel lines, and this is defined as one unit. If a plurality of units are used and the inner lines are alternately connected to the outer lines, a pleat state can be created.
When the embodiment shown in FIG. 1 is implemented with pleats, the method shown in FIG. 27 is used. The pleats are formed as a unit as shown in FIG. 31 and are connected and connected with inner lines and outer lines to create a pleated state. FIG.
28 is also possible with the pleats created.
And pleating (19) until the open side surface (22) is horizontal. This pleat (1
9) connects the molds as shown in FIG. 33 as one unit. In the application example of FIG. 17, only pleats to be created are possible. A cross sectional view of the rucksack side cut in the vertical direction, the outer shape is congruent, and the inner line is a parallel line, FIG.
4 is connected as one unit to create a pleated state. In the application example of FIG. 19, only the pleats to be created are possible, and the sheet is cut horizontally in the horizontal direction by the cutting method shown in FIG. 29, and a mold having the same outer shape as the cut surface, and FIG. produce. (B) The method of making pleats when the cross section of the open pleats of the bag changes varies as follows. In the representative example of FIG. 36, a case where the bucket type was cut in the horizontal direction and pleated was shown. The cutting of the mold for making pleats in this case is as shown in FIG. This is because not all the molds are the same, and only the lines at the points where the molds are connected are the same, and they are overlapped. By changing the shape of the entire pleat portion, it is only necessary to connect to the cross section of the bag. Thus, even if normal pleats are impossible due to the shape of the bag, the pleats created are
It can be implemented for many bags. These pleats can freely change the capacity of the bag depending on how to apply the pleats, that is, how to use elements such as the number of places where the pleats are applied, the width of the pleats, and the number. C. About a stop A stop is attached to a pleated part, and a pleat is expanded and contracted by using a stop, and what is suitable for each bag may be used. For example, there are fasteners, buttons, strings, and small metal fittings such as snaps, key hooks, pull-type stoppers, and plug-in stoppers.

[0015]

According to the present invention, the shape and the volume can be changed in one bag. The appearance of one bag with several shapes enriches it, and the unique shape and shading of pleats creates a new world of vision. In addition, since one bag shows several capacities, the practicality is greatly improved. As a result, the utility value of one bag increases. As described above, the present invention offers a new possibility for shaping bags.
