Description

  The present invention relates to a bag that can store, for example, purchased goods and the like, a method for manufacturing the bag, and a method for using the bag.

In recent years, when shopping at supermarkets and other various stores, the opportunity to use bags brought by consumers (so-called eco-bags) instead of shopping bags provided by stores as means for storing purchased products has increased. .
This bag has been mainly formed in the shape of a bag from the beginning, but a bag whose shape has been devised to improve convenience has been proposed.

  For example, in Patent Document 1 below, a square sheet is provided with two first strings and two second strings, the first string is used to form a square sheet into a bag shape, and the second string is A shopping bag to be used as a handle is described.

Patent Document 2 listed below describes a shopping bag that is formed in a shape that substantially matches the inner dimension of the regi basket, can be installed in the regi car, and can be folded when not in use.
Utility Model Registration No. 313511 JP 2003-144217 A

However, the shopping bag described in Patent Document 1 requires the work of tying two first strings when forming a rectangular sheet into a bag shape, and the work of tying the second string when forming a handle. Cost. That is, it is necessary to tie the string at least three times.
Moreover, although the shopping bag described in Patent Document 2 can be folded when not in use, it is inconvenient to carry because it has the same volume and shape as a regi-cart when storing articles. In particular, when the volume of articles to be stored is small, it becomes useless and bulky.
Accordingly, an object of the present invention is to provide a bag that can be formed into a form suitable for carrying while accommodating an article and then adjusting the volume of the container with a simple operation, and a method for manufacturing and using the bag. To do.

  In order to solve the above-described problem, a bag according to a main aspect of the present invention includes a flexible sheet main body having one end and the other end, and a storage portion formed between the one end and the other end, A movable member that moves between the one end and the other end so as to converge the sheet body from the one end side to form a converging portion and change the volume of the accommodating portion; and provided at the other end. And a fixing member for fixing the converging part so that a handle is formed.

According to this configuration, a portion of the flexible sheet main body that is not used for housing the article is bundled from one end with a movable member, that is, converged, so that the volume of the housing portion is matched to the volume of the contained material. The handle can be formed by fixing the converging portion formed by converging at the same time by a fixing member provided at the other end.
That is, it is possible to simultaneously adjust the volume of the accommodating portion and form the handle.
Therefore, after accommodating an article, it is possible to obtain a bag that can be formed into a form suitable for carrying while adjusting the volume of the accommodating portion with a simple operation.

  In the bag, the storage portion has an opening whose area is changed as the volume is changed, and the bag is provided along the opening, and the area of the opening is set regardless of the movable member. A variable member may be provided.

  Apart from the contraction of the opening due to the convergence, the member can arbitrarily contract the opening. In particular, when the volume of the stored item is large and the area of the opening is large, the bag can be formed in a form more suitable for carrying.

  In the bag, the movable member may be an annular member.

  The annular member can easily form the converging portion by passing the sheet main body through the ring.

  Moreover, the said fixing member may fix the said convergence part in the said bag so that the length of the said handle can be adjusted.

  According to this fixing member, it is possible to fix the converging portion with an arbitrary length and form a handle. That is, the length of the handle is not fixed by the movable member, and the handle can be formed to have a length that can be easily carried.

  The bag may further include a pocket that stores the surplus converging portion that is not formed as the handle by being fixed by the fixing member.

  Thereby, appearance can be prevented from being damaged by the surplus convergence part, or the surplus convergence part can be prevented from becoming an obstacle to carrying.

  In addition, the bag can be folded, and the pocket can store the folded bag.

  With this configuration, when the bag is folded and carried when not in use, the bag can be easily carried.

  In the bag, the seat body may include a reinforcing member that is provided on a bottom surface of the housing portion and that suppresses deformation of the seat body due to an accommodation housed in the housing portion.

  With this reinforcing member, deformation of the accommodation portion due to the shape of the accommodation can be suppressed, and the physical load on the seat body due to the weight of the accommodation portion can be reduced.

  Moreover, the said bag WHEREIN: The said sheet | seat main body shall consist of a raw material which has heat retention property.

  Thereby, the stored item can be kept warm.

  According to another aspect of the present invention, there is provided a bag manufacturing method, comprising: forming a flexible sheet body having one end and the other end; and a storage portion formed between the one end and the other end, and the sheet. A movable member that varies the volume of the housing portion while forming a converging portion by converging the main body from the one end side is provided between the one end and the other end, and the converging portion is held at the other end. The fixing member which fixes so that may be formed is provided.

  According to still another aspect of the present invention, there is provided a bag using a flexible sheet body having one end and the other end, and a storage portion formed between the one end and the other end. And moving the movable member provided between the one end and the other end of the seat body from the one end side to the other end side to form a converging portion while reducing the volume of the accommodating portion, A handle is formed by fixing the converging portion to a fixing member provided at the other end.

  As described above, according to the present invention, there is provided a bag that can be formed into a form suitable for carrying, while adjusting the volume of the storage portion by a simple operation after storing the article, and a method for manufacturing and using the bag. Can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an appearance of a bag according to an embodiment of the present invention when an item is not accommodated.
FIG. 2 is a perspective view showing the appearance of the bag when the item is accommodated.
As shown in both drawings, the bag 1 includes a seat body 2, a movable ring (movable member) 3, and a fixed ring (fixed member) 4.

  The sheet body 2 is formed of a flexible material. The material is not particularly limited as long as it is flexible, such as woven fabric, nonwoven fabric, and synthetic resin, but more preferably has durability and water resistance. It can also be formed by combining a plurality of materials. It is also possible to keep the contents warm by using a material having heat insulation properties.

As shown in FIG. 1, an accommodation portion 2 a is formed in the center portion of the sheet body 2. Further, the sheet body 2 has one end 2b and the other end 2c at opposite positions in the longitudinal direction. The accommodating portion 2a has an opening 2d, and is formed in a concave shape so as to easily accommodate the contents.
The sheet body 2 is provided with two wires 8 between one end 2b and the other end 2c as a reinforcing member that suppresses deformation caused by the contents. The wire 8 is preferably made of a material having high strength such as metal or synthetic resin.

  As shown in FIG. 1, a movable ring 3 as a movable member is provided at one end 2b. The movable ring 3 is slidable in the direction of arrow A in the state where the seat body 2 is inserted into the ring. The movable ring 3 can be formed of metal, synthetic resin, or the like. Since the movable ring 3 needs to slide with the seat body 2, the movable ring 3 is made of a material having a low friction coefficient and high durability with respect to the material of the seat body 2.

  Although details will be described later, when the movable ring 3 is slid in the direction of the arrow A in a state where the sheet main body 2 is inserted through the movable ring 3, the sheet main body 2 is converged and the converging portion 5 is formed. The inner diameter of the movable ring 3 is formed so as to be small enough to form the converging part 5 and is smaller than the width F in the short direction of the one end 2b. As a result, the one end 2 b serves as a stopper for the movable ring 3, thereby preventing the movable ring 3 from being detached from the seat body 2. The inner diameter is, for example, about 5 cm, but is not limited thereto, and can be appropriately changed according to the size of the sheet body 2.

As shown in FIG.1 and FIG.2, the other end 2c is provided with the fixing ring 4 as a fixing member. The fixing ring 4 includes two rings. The two rings of the fixing ring 4 are rotatably supported on the same axis on one side of the end cover 11 connected to the seat body 2 by, for example, sewing. The fixing ring 4 can fix the converging part 5 by sandwiching the two rings through the converging part 5. The fixing ring 4 can be formed of a strong metal, synthetic resin, or the like.
As shown in FIG. 2, the converging part 5 fixed to the fixing ring 4 forms a handle 10.

As shown in FIGS. 1 and 2, the bag 1 has a tubular string passage portion 7 provided along the opening 2 d of the housing portion 5. The stringing portion 7 is formed by folding and sewing the sheet body 2.
The string 6 is inserted through the string passing part 7. The string 6 is made of a material such as fiber or synthetic resin, for example, and the area of the opening 2d can be varied by narrowing the sheet body 2. Further, the string 6 is provided with a string clip 13 for fixing the squeezed string 6. The string fastening clip 13 has a hole through which the string 6 can be inserted and an elastic member (not shown) such as a spring for opening and closing the hole, and can fix the string 6. It has become.

  As shown in FIG. 2, a pocket 9 is provided on the back surface (the side surface when the contents are stored) on the other end 2 c side of the sheet body 2. In this pocket 9, it is possible to store a surplus portion 5 a of the converging portion 5 that is not formed as a handle 10, in addition to a relatively small container (small item).

Next, operation | movement of the bag 1 of this embodiment is demonstrated. Here, a procedure for forming the bag 1 from a state when not in use to a state where the stored item can be stored and carried during shopping will be described with reference to FIGS. 1 to 7.
FIG. 3 is a plan view showing an appearance of the bag 1 when not in use.
FIG. 4 is a perspective view showing an appearance of the bag 1 in a state where the bag 1 is disposed on the regi- basket.
FIG. 5 is a perspective view showing an appearance in a state where the bag 1 is converged.
FIG. 6 is a perspective view showing the appearance of the bag 1 with the handle formed.
FIG. 7 is a perspective view showing an appearance when the bag 1 is carried.
FIG. 8 is a perspective view showing how the bag 1 is folded when not in use. FIG. 8A shows a state in which a part of the bag 1 is folded, and FIG. 8B shows a state in which the bag 1 is stored in a pocket.

As shown in FIG. 3, the opening 2d of the bag 1 is closed when not in use. From this state, the user opens the opening 2d in the direction of the arrow B to form the accommodating portion 2a shown in FIG.
Subsequently, the user puts the bag 1 in the state shown in FIG. 1 on the registration basket C as shown in FIG. 4 and installs it so as to conform to the inner shape of the registration basket C.
In this state, the user stores the item (product) in the storage unit 2a.

  Subsequently, as shown in FIG. 5, the user slides the movable ring 3 from the one end 2b toward the other end 2c. Thereby, the converging part 5 is formed between the one end 2b and the movable ring 3, and at the same time, the volume of the accommodating part 2a is reduced. The volume of the accommodating part 2a is appropriately adjusted according to the volume and shape of the contents.

Subsequently, as shown in FIG. 6, the user inserts the formed converging part 5 into the fixing ring 4 from the one end 2 b side, so that the handle 10 having a length easy to carry the converging part 5 is formed. And fix with the fixing ring 4.
Next, as shown in FIG. 2, the user squeezes the sheet body 2 with the string 6, adjusts the area of the opening 2 d, and fixes the string 6 with the string clip 13.
Subsequently, as shown in FIG. 7, the user stores the surplus portion 5 a of the converging portion 5 which is surplus without being formed as the handle 10 in the pocket 9.
By the above procedure, as shown in FIG. 7, the bag 1 can be formed in a portable state.

Further, the user can fold the bag 1 when the bag 1 is not in use.
In this case, the sheet body 2 is further folded from the state in which the opening 2d is closed so that the sheet body 2 becomes narrower in the lateral direction. Next, as shown in FIG. 8 (A), the user folds from one end 2b so as to be shorter in the longitudinal direction, and folds up to the other end 2c as shown in FIG. 8 (B). The sheet body 2 is accommodated in 9.

  Next, the manufacturing method of the bag 1 of this embodiment is demonstrated.

FIG. 12 is a plan view of the seat body 2 to which the movable ring 3 is attached.
FIG. 13 is a plan view of the seat body 2 to which the fixing ring 4 is attached. FIG. 13A shows the front surface (surface having the opening 2d), and FIG. 13B shows the back surface.

As shown in FIG. 9, the manufacturer first forms the tubular string passage portion 7 by folding the two opposite longitudinal sides of the rectangular sheet body 2 inward (short direction) and sewing them. .
Subsequently, the manufacturer provides holes 2e in each string passing portion 7 with a predetermined interval E from the other end 2c.
Subsequently, the manufacturer inserts the string 6 between one end 2 b of each string passing part 7 and the hole 2 e and extends the hole 2 e to the outside of the string passing part 7.

Subsequently, as shown in FIGS. 9 and 10, the manufacturer folds the sheet body 2 by valley folding at the fold line D1, mountain folding at the fold line D2, and valley folding at the fold line D3.
Subsequently, as shown in FIG. 11, the manufacturer fixes the sheet body 2 together with the string 6 by folding the one end 2 b inward and sewing it.

Subsequently, as shown in FIG. 12, the manufacturer inserts the sheet body 2 into the ring of the movable ring 3. As described above, since the inner diameter of the movable ring 3 is smaller than the width of the folded portion of the one end 2b, the movable ring 3 is prevented from coming off from the one end 2b.
Subsequently, the manufacturer collects the sheet body 2 near the other end 2c, and attaches the end cover 11 by sewing or the like as shown in FIGS. 13 (A) and 13 (B). The manufacturer also installs the fixed ring 4 composed of two rings on the opposite side of the end cover 11 from the side on which the seat body 2 is mounted, with the same shaft.
Subsequently, as shown in FIG. 13B, the manufacturer provides a pocket 9 on the back surface of the sheet body 2 in the vicinity of the other end 2c.

Subsequently, the manufacturer attaches the strap clip 13 to the strap 6 as shown in FIG.
The bag 1 of this embodiment is manufactured by the above manufacturing method.

  Embodiments according to the present invention are not limited to the embodiments described above, and other various embodiments are conceivable.

The shape of the sheet body 2 is not limited to the rectangular shape described above, and is appropriately selected in consideration of a method for forming the accommodating portion 2a described later. For example, the sheet body 2 may be oval, rhombus, or the like, or may be composed of a plurality of members.
FIG. 14 is a perspective view of the seat body 2 of a bag according to another embodiment of the present invention.
In the above-mentioned embodiment, the method of folding a planar member was shown as a method of forming the accommodating portion 2a in the sheet main body 2. However, the accommodating part 2a is not limited to this, For example, as shown in FIG. 14, it forms by sewing one or several members so that the center may become concave shape. As described above, the method of forming the storage portion, the depth of the storage portion, and the area of the opening 2d are appropriately changed according to the volume of the storage item.

  In the above-described embodiment, the two wires 8 are shown as the above-described reinforcing member, but other configurations are also possible. The number of the wires 8 may be changed as appropriate, and may be arranged in a direction orthogonal to the wires 8 in FIG. The reinforcing member is not limited to a wire, and can be formed of a material having a reinforcing effect, such as a plate member made of resin or paper.

FIG. 15 is a plan view of the seat body 2 of a bag according to still another embodiment of the present invention.
In the above-described embodiment, the configuration in which the two strings 6 are provided in the longitudinal direction of the sheet main body 2 is shown. However, the number of strings and the installation direction can be changed as appropriate. For example, as shown in FIG. 15, a plurality of flexible tubular members 14 are attached in parallel in the short direction of the sheet main body 2, and a string 15 (or rubber or the like) is inserted through the tubular member 14. It is possible to adopt a structure in which both ends of 15 are extended in the lateral direction of the sheet body 2. Also in this case, each string 15 can be provided with a string clip similar to that of the above-described embodiment. With this configuration, the sheet main body 2 can be squeezed in the short direction after accommodating the accommodation in the accommodating portion 2a, and the size of the accommodating portion 2a can be easily changed, or the accommodating portion 2a can be divided into a plurality of accommodating areas. It becomes possible to do.
Also, with this configuration, when the converging portion is formed by the movable member and when the handle is formed by the fixed member, the cylindrical member 14 comes into contact with the movable member and the fixed member, so that the converging portion and the handle stopper are formed. Function as. Thereby, the bag 1 can be carried in a more stable state.

In the above-mentioned embodiment, although the movable ring 3 was shown as a movable member, it is not restricted to this. For example, the convergent portion 5 can be formed even when a ring partially missing (not linked) is used as the movable member. Further, instead of a circular annular member, a rectangular or other polygonal annular member may be used. Moreover, you may use not only an annular member like a ring but a cylindrical member. When the cylindrical member is used, the contact area with the sheet main body 2 is larger than that in the case of the annular member. Therefore, after the converging portion 5 is formed, the position is easily maintained.
Furthermore, this cylindrical member can be formed into a tapered ring shape having different diameters at one end and the other end. In this case, the taper ring is arranged on the one end 2b side with the smaller diameter side. With this configuration, the converging part 5 can be formed more easily.

  In the above-described embodiment, the fixing ring 4 including two rings is shown as the fixing member, but the configuration is not limited thereto. For example, a hook-and-loop fastener, a belt fixing tool for clothing, and the like may be used. Moreover, it can be set as the structure fixed together with the fastener etc. which were provided individually or intermittently on the convergence part 5, and a thing of a magnet type, a fitting type, etc. can be used in this case. .

In the above-described embodiment, the string 6 is shown as means for adjusting the area of the opening 2d, but other configurations are possible. For example, a button, a line fastener, a hook-and-loop fastener provided along the opening 2d may be used. In addition, depending on the volume of the accommodating portion 2a, a means for adjusting the area of the opening 2d may not be provided.
Of course, the above-described tying clip 13 can be replaced by other means.

  In the above-described embodiment, the pocket 9 is formed so as to be able to store the entire bag 1, but is not limited to this configuration. For example, you may form so that only the surplus part 5a of the convergence part 5 surplus without being formed as the handle 10 can be accommodated. It is also possible not to form the pocket 9. In addition, the pocket 9 stores a relatively small accessory bag for storing, for example, a raw item or the like that the user wants to store separately from other items (products) of the bag 1. Also good. Furthermore, you may provide separately the pocket which can accommodate an accessory etc. inside the accommodating part 2a, for example.
