Description

  The present invention relates to a bag having a plurality of storage sections.

  Conventionally, a bag having a plurality of storage sections is known. For example, the wet bag described in Patent Literature 1 includes a bag body provided with a water-permeable means at a bottom portion, and a cover body capable of housing the bag body. According to this configuration, an object can be stored at a plurality of locations between the bag body and the bag body and the cover body.

JP 2007-275487 A

  However, in the conventional example, storage portions are provided at a plurality of locations between the bag main body (inner bag) and the bag main body and the cover body (outer bag). Therefore, so-called two bags, a bag body and a cover body, are required. Therefore, there is a problem that the number of parts increases and the production cost increases.

  An object of the present invention is to solve the conventional problem, and it is an object of the present invention to provide a bag in which one bag-shaped member as a material is folded to form a plurality of storage portions.

  The bag according to the aspect of the present invention includes a first storage portion and a second storage portion formed by a bag-shaped member including a first bottom portion and a side portion extending upward in a vertical direction with respect to the first bottom portion. When the direction perpendicular to the vertical direction is a plane direction, the first storage portion is formed in a bag shape by the first bottom portion and a first side portion that is a part of the side portion, and A first opening is formed by a first ridgeline in which a part of the portion is bent toward the outside in the plane direction, and the second storage portion forms the first storage portion in the plane direction. One side portion and a second side portion formed by bending the side portion at the first ridgeline are formed in an annular shape outside the first storage portion, and the second storage portion is , In the up-down direction, the side of the second side opposite to the side that is continuous with the first side A second ridgeline is an end, is enclosed in said first side, wherein the second opening in the plane direction is formed.

  According to this, the first storage portion and the second storage portion are formed by the bag-shaped member. The first storage portion is formed in a bag shape by a first bottom portion and a first side portion that is a part of the side portion. The second storage portion is formed in a ring shape by being sandwiched between a first side portion forming the first storage portion and a second side portion formed by bending the first side portion at the first ridge line. A second opening is formed in a planar direction surrounded by the two ridges and the first side. Therefore, the number of parts of the bag is reduced, and the production cost can be reduced.

  In the bag, a second opening may be formed below the second storage unit in the up-down direction, and may be formed in a direction opposite to the first opening in the up-down direction. In this case, when the bag is used with the first opening facing upward, it is difficult for rain or dust to enter the second storage portion. In addition, since the first opening and the second opening are on opposite sides in the vertical direction, it is easy to insert an object when storing an object in each of the first storage section and the second storage section.

  In addition, the bag includes a first joining member that joins the lower end of the second side portion in the vertical direction and the lower end of the first side portion in the vertical direction. The second opening may be closed and the second bottom may be formed by joining the first joining members to each other.

  In this case, since the second storage portion forms the second bottom portion by closing the second opening portion, when the bag is held with the first opening portion facing upward, the second storage portion is stored from the second opening portion. Objects can be prevented from falling.

  In addition, the bag may include a joint portion where the first ridge line is joined to the first side portion and the second side portion. In this case, by joining the first ridge line by the joining portion, the rigidity of the first opening is increased, and the position of the first opening in the vertical direction can be prevented from changing.

  In the bag, the joint may be fixed. In this case, by fixing the joint at the first ridge line, the rigidity of the first ridge line is increased, and the position of the first opening in the vertical direction can be prevented from changing.

  Further, in the bag, the joining portion at the first ridgeline includes a second joining member, the second joining member is separable, and the second joining member is separated to move the second side portion up and down. When extended in the upper direction of the direction, only the first storage portion may be provided.

  In this case, the user can select and use the state in which the user has the first storage section and the second storage section and the state in which the bag has only the first storage section in which the amount that can be stored is increased. The form can be changed according to the intended use.

  In the bag, the second side may be transparent. In this case, the object stored in the second storage unit can be visually observed from the outside.

  Further, the bag may include a handle from the inside of the first storage portion toward the upper side in the up-down direction. In this case, the handle is not attached to the second side, so that the appearance is good. Further, when the second side portion is transparent, the object stored in the second storage portion can be visually observed from outside in a wider range.

  Hereinafter, a bag 1 embodying the present invention will be described with reference to the drawings. The drawings referred to are used to explain the technical features that can be adopted by the present invention. The configuration of the device illustrated in the drawings is not intended to limit the present invention, but is merely an example.

<Common configuration of bag 1>
The outline of the bag 1 will be described with reference to FIGS. The bag 1a of the first embodiment to the bag 1d of the fourth embodiment will be described later, but first, a common configuration will be described. The bag 1 includes a first storage part 2 and a second storage part 3 formed by a bag-shaped member 50 including a first bottom part 4 and a side part 5 extending upward in the up-down direction with respect to the first bottom part 4. Prepare. The direction orthogonal to the up-down direction is defined as the plane direction. Note that the bag 1 will be described assuming that the first bottom 4 is at the lower end in the up-down direction.

  The first storage part 2 is formed in a bag shape by the first bottom part 4 and the first side part 5a which is a part of the side part 5, and a part of the side part 5 is bent outward in the plane direction. The first opening 6 is formed by the first ridge line 6a. The second storage part 3 is sandwiched between a first side part 5a forming the first storage part 2 and a second side part 8 formed by bending the side part 5 at the first ridge line 6a in the plane direction. Then, it is formed annularly outside the first storage section 2. The second storage portion 3 is surrounded by a second ridge line 9a which is an end of the second side portion 8 on the opposite side to a side continuous with the first side portion 5a in the vertical direction, and the first side portion 5a. As a result, a second opening 9 is formed in the plane direction. As will be described later, in the bag 1a of the first embodiment to the bag 1c of the third embodiment, the second ridgeline 9a and the second opening 9 are formed on the lower side in the vertical direction. In the bag 1d of the fourth embodiment, the second ridge line 9a and the second opening 9 are formed on the upper side in the up-down direction. The first side portion 5a and the second side portion 8 are both formed by the side portion 5.

  The outer side and the inner side in the plane direction will be described in more detail. The first opening 6, the first storage part 2, the second opening 9, and the second storage part 3 are formed in a ring shape, and the direction away from the center is the outside with respect to the center in the planar direction. , The direction toward the center is the inside. For example, as shown in FIG. 2, in the first ridgeline 6a of the first opening 6, the direction away from the center of the first opening 6 is outside the first ridgeline 6a, and the direction toward the center is the first ridgeline 6a. Inside. The direction in which the first ridge line 6a and the second ridge line 9a are formed is defined as a circumferential direction. The 2nd storage part 3 is formed in the circumference of the 1st storage part 2 at the outer side of a plane direction, and is annular in the circumferential direction.

  Various materials can be selected for the bag 1. Although a flexible material is preferable, for example, a resin material such as polyethylene, nylon, or vinyl, or a polyester fiber or a polyurethane fiber can be selected. Other materials can be selected without departing from the spirit of the present invention.

  The second side 8 is transparent. As shown in FIGS. 2 and 4, when the object 100 is stored in the second storage unit 3, the object 100 can be visually recognized from the outside. Further, not only the second side portion 8 but also all other elements including the first side portion 5a may be transparent. Alternatively, only the second side 8 may be transparent.

  As shown in FIGS. 1 to 4, the bag 1 is provided with a handle 18 a upward from the inside of the first storage section 2. A reinforcing member 30 is attached to the periphery of the support 18a on the inner side in the planar direction of the first side portion 5a. In FIG. 1, the reinforcing member 30 is attached to only a part of the periphery of the handle 18a, but may be attached to the entire circumference in the circumferential direction. When the second side part 8 is transparent, the object 100 stored in the second storage part 3 is visible from the outside without being blocked by the handle 18 a or the reinforcing member 30.

  As shown in FIGS. 2 and 3, a plurality of third joining members 31 are attached to the inside of the first side portion 5a in the plane direction. FIG. 3A shows a state where the third joining member 31 is separated and the first opening 6 is opened, and FIG. 3B shows a state where the opposing third joining members 31 are joined to each other. This shows a state where one opening 6 is closed.

<Configuration of Bag 1a of First Embodiment>
Next, the bag 1a according to the first embodiment of the present invention will be described. As shown in FIGS. 1, 6, and 7, the second opening 9 is formed below the second storage unit 3, and is formed in a direction opposite to the first opening 6 in the up-down direction. That is, the first storage section 2 and the second storage section 3 have opposite directions in which the object 100 is inserted.

  In addition, as shown in FIGS. 1 and 5 to 7, the lower end of the second side portion 8 and the lower end of the first side portion 5a of the bag 1a are joined to each other. One joining member 10 is provided. When the first joining member 10 is joined, the second opening 9 is closed and the second bottom 7 is formed. Since the second storage portion 3 has the second opening 9 formed on the lower side in the up-down direction, the bag 1a is normally turned upside down, the object 100 is inserted, and then the first joining member 10 is joined. And close.

  Further, the bag 1a includes a joint portion 11 in which the first ridge line 6a is joined to the first side portion 5a and the second side portion 8. As shown in FIG. 7, the joint 11 of the bag 1a is fixed. The second storage portion 3 is formed by bending a bag-shaped member 50a continuous from the first side portion 5a at the first ridgeline 6a, and the joint portion 11 is formed at the bent portion. In the bag 1a, a boundary between the first storage section 2 and the second storage section 3 is formed by the joint section 11.

<Configuration of Bag 1b of Second Embodiment>
Next, a bag 1b according to a second embodiment of the present invention will be described. The same components as those of the bag 1a of the first embodiment are denoted by the same reference numerals or omitted, and the description may be omitted. The same applies to a bag 1c according to a third embodiment described later and a bag 1d according to a fourth embodiment.

  As shown in FIGS. 8 and 9, in the bag 1 b, the joint 11 at the first ridgeline 6 a includes the second joint member 12, and the second joint member 12 is separable. FIG. 8 shows a state in which the joining portion 11 of the bag 1b is joined by the second joining member 12. FIG. 8A shows a case where the second joint member 12 is the hook-and-loop fastener 41, and FIG. 8B shows a case where the second joint member 12 is the button 42. In any case, the second joining member 12 can be separated.

  Further, as shown in FIG. 9, the bag 1b has only the first storage portion 2 when the second joining member 12 is separated and the second side portion 8 is extended upward. In this case, the vertical length of the first storage portion 2 is substantially equal to the length obtained by adding the vertical length of the first storage portion 2 and the second storage portion 3 in FIG.

  Although not shown, the handle 18a can be removed with a hook-and-loop fastener or a button. The place where the chin 18a is attached is not limited to one place, but can be attached to a plurality of places. The bag 1b can be selected between a state in which the first storage section 2 and the second storage section 3 are provided as shown in FIG. 8A and a state in which only the first storage section 2 is provided as shown in FIG. Is possible. In this case, since the optimal position and orientation of the attachment of the hand 18a are different, the attachment position of the hand 18a can be changed depending on the form of the bag 1b.

<Configuration of Bag 1c of Third Embodiment>
Next, a bag 1c according to a third embodiment of the present invention will be described. In the bag 1c, the position of the handle 18 is different from the bag 1a of the first embodiment and the bag 1b of the second embodiment. The other configuration is the same as that of the bag 1a or the bag 1b, and the description is omitted. As shown in FIGS. 10 and 11, the handle 18 b of the bag 1 c is provided outside the second side portion 8 in the planar direction.

<Configuration of Bag 1d of Embodiment 4>
Next, a bag 1d according to a fourth embodiment of the present invention will be described. Unlike the bag 1a of the first embodiment to the bag 1c of the third embodiment, the bag 1d has the first opening 6 and the second opening 9 opened in the same vertical direction. As shown in FIGS. 12 and 13, the second storage portion 3 is formed by bending the side portion 5 of the bag-shaped member 50b twice. Details of the manufacturing method will be described later.

<Method for Manufacturing Bags 1a and 1b>
Next, a method of manufacturing the bag 1a will be described with reference to FIGS. The vertical direction will be described on the assumption that the bag 1a is completed. 5 to 7 are views corresponding to the cross section BB in FIG. FIG. 5A shows a state in which the handle 18a is attached to the bag-shaped member 50a (50) in advance. The two-dot chain line 51a is a fold line indicating the position where the first opening 6 is formed and is a virtual line. Inside the bag-like member 50a (50) in the planar direction, the first joining member 10 (for example, a hook-and-loop fastener or a button) forming the second bottom 7 is attached at a plurality of locations. The hand 18a is attached to the side portion 5 outside in the planar direction.

  As shown in FIG. 5B, the upper part of the bag-shaped member 50a in the up-down direction is folded downward to form a concave portion serving as the first storage part 2. FIG. 5B shows a process in which the bag-shaped member 50a is folded.

  FIG. 6A shows a state where the bag-shaped member 50a is folded to a predetermined position. In this state, the second opening 9 is formed so as to open downward. FIG. 6B shows a state in which the joint portion 11 is fixed with respect to FIG. The joining portion 11 is joined and fixed by heat welding, bonding or another method. On the other hand, the bag 1b of the second embodiment is detachably joined by the hook-and-loop fastener 41 or the button 42.

  The state of FIG. 6B shows a mode in which the bag 1a is sold or the like. FIG. 7 shows a state where the object 100 is inserted into the second storage section 3 of the bag 1a shown in FIG. 6B. The object 100 is inserted through the second opening 9. The upper end of the second storage portion 3 in the up-down direction is joined at the joining portion 11, so that the object 100 does not deviate from the second storage portion 3. FIG. 1 shows a state in which the second opening 9 is further closed by the first joining member 10 to form the second bottom 7 from FIG.

  The example has been described in which the support 18a and the reinforcing member 30 are attached to the outside of the bag-shaped member 50a in the planar direction in advance, but the invention is not limited thereto. For example, in the state shown in FIG. 6B, the handle 18a and the reinforcing member 30 may be attached later. The support 18a may not be fixedly attached. Note that the bag 1c of the third embodiment is different from the bag 1a or the bag 1b only in the position of the fulcrum 18, and the description of the manufacturing method is omitted.

<Method for manufacturing bag 1d>
Next, a method of manufacturing the bag 1d according to the fourth embodiment will be described with reference to FIGS. As shown in FIG. 12A, the vertical size of the bag-shaped member 50b in the bag 1d is longer than the bag-shaped members 50a of the bags 1a to 1c. Two two-dot chain lines 51b are bending lines and imaginary lines indicating positions where the first openings 6 are formed. Unlike the bags 1a to 1c, the number of times the bag-shaped member 50b is bent is two times. Since the bag-shaped member 50b requires two-fold bending, a material that is relatively flexible and can be expanded and contracted is suitable. Alternatively, the bag-shaped member 50b is selected to have a small thickness.

  As shown in FIG. 12 (b), the lower part of the bag-shaped member 50b in the vertical direction is turned upside down at the position of the upper two-dot chain line 51b from the state of FIG. 12 (a). Further, as shown in FIG. 13 (a), it is bent downward at the position of the lower two-dot chain line 51b and turned over again. The first side portions 5 a overlap doubly in the vertical direction and are fixed at the side joint portions 52. The first opening 6 and the second opening 9 open in the same direction in the vertical direction. As shown in FIG. 13B, the object 100 is inserted from the second opening 9, and the first opening 10 closes the second opening 9.

<Common functions and effects>
As described above, the bag 1 has various effects. First, operations and effects common to the bag 1a of the first embodiment to the bag 1d of the fourth embodiment will be described. As shown in FIGS. 1 to 4, in the bag 1, the first storage section 2 and the second storage section 3 are formed by the bag-shaped member 50. The first storage part 2 is formed in a bag shape by the first bottom part 4 and the first side part 5a which is a part of the side part 5, and a part of the side part 5 is bent outward in the plane direction. The first opening 6 is formed by the first ridge line 6a. The second storage part 3 is sandwiched between a first side part 5a forming the first storage part 2 and a second side part 8 formed by bending the side part 5 at the first ridge line 6a in the plane direction. Then, it is formed annularly outside the first storage section 2. The second storage portion 3 is surrounded by a second ridge line 9a which is an end of the second side portion 8 on the opposite side to a side continuous with the first side portion 5a in the vertical direction, and the first side portion 5a. As a result, a second opening 9 is formed in the plane direction. That is, since the bag 1 has two storage portions formed by one bag-shaped member 50, the number of parts is reduced and the production cost can be reduced.

  In addition, since the second storage portion 3 is formed in a ring shape in the circumferential direction, for example, a band processed product having a ring shape can be stored as it is. Alternatively, since the second storage unit 3 has a smaller storage width in the planar direction than the first storage unit 2, even if the second storage unit 3 is rolled or folded like a certificate of medal or continuous paper, it is formed in an annular shape. Can be stored as it is.

  The second side 8 forming the outer periphery of the bag 1 is transparent. As shown in FIGS. 2 and 4, when the object 100 is stored in the second storage unit 3, the object 100 can be visually recognized from the outside. Therefore, for example, when the object 100 is a band-shaped product formed in an annular shape having a Japanese-style and gorgeous pattern, the object 100 is stored in the second storage portion 3 so that the pattern surface is outside in the plane direction, so that the appearance is improved. It is very gorgeous. Alternatively, in the case where the object 100 is a flyer for advertisement, if the object 100 is stored in the second storage section 3, the contents of the advertisement can be viewed from the outside, so that the bag 1 functions as an advertising tower.

  As shown in FIG. 2 and FIG. 3, a plurality of third joining members 31 are attached to the inside of the first side portion 5a in the plane direction. Therefore, the first opening 6 can be closed by joining the third joining member 31. Alternatively, the first opening 6 can be opened by separating the third joining member 31.

<Operation and Effect of Bag 1a of First Embodiment>
Next, the operation and effects of the bag 1a of the first embodiment according to the present invention will be described. As shown in FIGS. 1, 6, and 7, the second opening 9 is formed below the second storage unit 3, and is formed in a direction opposite to the first opening 6 in the up-down direction. In this case, when the bag 1a is used with the first opening 6 on the upper side, rain or dust or the like hardly enters the second storage portion 3. In addition, since the first opening 6 and the second opening 9 are opposite to each other in the up-down direction, it is easy to insert the object 100 into each of the first storage 2 and the second storage 3 when storing them.

  For example, in order to make the appearance of the bag 1a decorative, it is conceivable to insert a processed band product as the object 100 into the second storage section 3. In this case, the frequency of exchanging the processed band into the second storage unit 3 is lower than the frequency of inserting the object 100 into the first storage unit 2. Since the first storage unit 2 frequently exchanges the object 100, the insertion is performed from the upper side in the up-down direction. Since the second storage unit 3 has a relatively low replacement frequency of the object 100, it is reasonable to insert the object 100 from the lower side in the vertical direction. Further, when the object 100 is inserted, it is easier to insert the object 100 at a different position in the vertical direction than when the first opening 6 and the second opening 9 are adjacent to each other.

  Further, as shown in FIG. 1, the second opening 9 is closed by joining the first joining member 10 to the bag 1 a to form the second bottom 7. In this case, when the bag 1a is held with the first opening 6 facing upward, the stored object 100 can be prevented from falling from the second opening 9.

  In addition, as shown in FIGS. 1 to 4, the bag 1 a includes a joint 11 in which the first opening 6 is joined to the first side 5 a and the second side 8. In this case, since the first opening 6 is joined by the joining portion 11, the position of the first opening 6 in the vertical direction can be prevented from changing. In addition, the rigidity of the first opening 6 is further increased by fixing the joint 11.

  As shown in FIGS. 1 to 4, the bag 1 includes a handle 18 a from the inside of the first storage section 2 to the upper side. Therefore, since the second side portion 8 which is the outer periphery of the bag 1 does not have the handle 18a, the object 100 inserted into the second storage portion 3 is not blocked. Furthermore, since the handle 18a is attached to the inside of the first side portion 5a in the planar direction, it is easy to hold even if a heavy object is stored in the first storage portion 2. This is common to the bags 1 (1a, 1b, 1d) except for the bag 1c of the third embodiment.

<Operation / Effect of Bag 1b of Second Embodiment>
Next, the operation and effect of the bag 1b of the second embodiment will be described. As shown in FIGS. 8 and 9, the second joining member 12 of the bag 1b is separable. When the second joining member 12 is separated and the second side portion 8 is extended in the upper direction, the bag 1b can have only the first storage portion 2 whose length in the vertical direction is longer. Therefore, the bag 1b can be selectively used between a state having two storage sections of the first storage section 2 and the second storage section 3 and a state having only one storage section of the first storage section 2. . The state of the bag 1b can be selected according to the type, size, or amount of the object 100 to be stored.

<Operation / Effect of Bag 1c of Third Embodiment>
Next, the operation and effect of the bag 1c of the third embodiment will be described. As shown in FIGS. 10 and 11, the handle 18 b of the bag 1 c is provided outside the second side portion 8 in the planar direction. Therefore, since the first side portion 5a does not have the handle 18b, the object 100 is easily stored without being obstructed when the object 100 is inserted into the first storage portion 2.

<Operation and Effect of Bag 1d of Fourth Embodiment>
Next, the operation and effect of the bag 1d of the fourth embodiment will be described. As shown in FIG. 13, the first opening 6 and the second opening 9 open in the same vertical direction. Therefore, when inserting the thing 100 into the 1st storage part 2 and the 2nd storage part 3, it can insert from the same direction. Further, the first side portion 5a overlaps vertically in a double manner and is fixed at the side joint portion 52, so that the rigidity of the first storage portion 2 is increased.

<Modification>
Note that the present invention is not limited to the above embodiment, and various modifications are possible.
