Description

  The present invention relates to a container for storing various small items such as coins, bills, cosmetics, writing instruments, and the like, and more particularly, to a pouch that is easy to open and use.

  There exists what was disclosed by patent document 1 as a pouch which is easy to open. This is a pouch with a structure in which the front part and the rear part face each other across the storage space and are connected and integrated at the bottom part, and the upper part and the three sides of the side part open, and the inner surface of the front part and the rear part that separates when opened It is the structure provided with resin-made board members. The plate member has a wide and rectangular plate shape that is one third or more of the width of the front surface portion and the rear surface portion, and both end portions in the width direction are fixed to upper end portions of the front surface portion and the rear surface portion. For this reason, the plate member has a substantially U-shaped cross section when the pouch is closed.

  When this pouch is opened, the upper end portions of the front surface portion and the rear surface portion are separated from each other by the urging force of the plate member, and a wide opening is automatically obtained. In addition, since the bottom portion corresponding to the bottom surface portion of the plate member rises with the opening, there is an effect that the stored item can be easily taken out.

  However, the plate member is exposed on the inner surface of the pouch. In particular, since the plate member has a structure that floats from the bottom surface portion, the stored item may sink under the plate member. In this case, it is difficult to take out the stored items, and an extra load is applied to the slide fastener of the opening when the mouth is closed.

  Patent Document 2 also discloses a pouch that is easy to open, similar to the pouch of Patent Document 1. This pouch is provided with a plate portion corresponding to the plate member of Patent Document 1 so as to be removable. This is because if the resin plate portion is used for a long period of time, it will bend and become flat so that it can be removed and stretched flat to recover its restoring force.

  Whatever the reason, if the plate part can be removed in this way, the stored item cannot be taken out.

  However, it is troublesome to remove the plate portion each time, and the inconvenience in the case where the mouth is closed while the stored item is under the plate portion cannot be solved.

  Accordingly, the main object of the present invention is to provide an easy-to-use pouch that can be easily opened without causing any inconvenience in taking out stored items and closing the mouth.

  For that purpose, the front part, the rear part, the side parts on the left and right sides and the bottom part surround the storage space and the bottom side, and the upper side of each of the front part, the rear part and the side parts on the left and right sides A pouch having a structure that forms an opening and closing portion, and the opening and closing portion is opened and closed by a fastener, and a lining disposed inside each of the front surface portion, the rear surface portion, the left and right side surface portions, and the bottom surface portion, It is a pouch provided with a spring member which is arranged on the outside of the lining and biases the upper sides of each of the front surface portion and the rear surface portion in directions away from each other.

  In this configuration, since the opening / closing part can be fully opened by the biasing force of the spring member simply by removing the fastener, the opening / closing part can be easily opened. Furthermore, since the fully open state can be maintained by the biasing force of the spring member, the stored item can be easily taken out. In addition, since the spring member is disposed outside the lining (that is, the spring member is not exposed to the storage space), the stored item is likely to sink under the spring member, and it is difficult to take out, or the opening / closing part is difficult to close. Can be prevented from occurring. For this reason, it becomes a very easy-to-use pouch.

  The spring member is rod-shaped, and is elastically deformed so that both end portions face upward and the central portion is curved and protrudes downward, and the side portions on both the left and right sides and the lining on the inside thereof It may be arranged between.

  In this configuration, since the spring member is arranged in a portion that is not touched so much in the pouch, the spring member can be provided without impairing the touch comfort of the pouch. In addition, since the central part of each of the front and rear sides of the opening / closing part is not curved outward by the biasing force of the spring member, the outline of the opening / closing part in the fully opened state can be maintained in a substantially rectangular state, and the appearance of the pouch Is beautiful. Furthermore, since the spring member is rod-shaped, even if the spring member is disposed between the side portions on both the left and right sides and the inner lining, the swelling of the side portion due to the spring member is suppressed, so the spring member is disposed. It is difficult to understand what is being done, and this also makes the pouch look beautiful. Further, since the spring member is elastically deformed so that both end portions face upward and the central portion is curved and protrudes downward, the touch comfort and the appearance of the pouch are secured as described above. The urging force of the spring member can be sufficiently exerted.

  The spring member may be a coil spring that is in close contact with the line when there is no load. In this configuration, since the contact area between the spring member and the side surface and the lining can be reduced and the frictional resistance can be reduced, the biasing force of the spring member can be weakened by the frictional resistance when the spring member opens the opening / closing part. It is possible to effectively exhibit the opening / closing portion without opening.

  The spring member may be made of metal. In this configuration, even if the spring member is formed to be relatively thin, a sufficient urging force for opening the opening / closing portion can be secured. If the spring member is formed to be relatively thin, even if the spring member is disposed between the side surface portion and the inner lining, the swelling of the side surface portion due to the spring member is suppressed, so the spring member is disposed. This can make it difficult to understand.

  The spring member may have a rod shape with an outer diameter of 3 mm to 4 mm. In this configuration, since the spring member is formed relatively thin, even if the spring member is disposed between the side surface portion and the inner lining, the swelling of the side surface portion due to the spring member can be suppressed, and the spring member is disposed. It is difficult to understand what is being done.

  The spring member may be a coil spring having a wire diameter of 0.8 mm to 1.2 mm. In this configuration, a coil spring formed relatively thin (that is, having a small outer diameter) can be used as the spring member while ensuring a sufficient urging force.

  Both end portions of the spring member may be disposed near both ends of the upper side of the side surface portion. In this configuration, the biasing force of the spring member can be effectively exhibited in order to open the opening / closing part.

  The curved portion of the spring member may be disposed near the center in the vertical direction of the side surface portion. In this configuration, since it is possible to prevent the spring member from being lowered too much, both ends of the spring member are arranged near both ends of the upper side of the side surface portion in a state where the spring member is curved relatively shallowly in a substantially V shape. This makes it possible to cause the spring member to exert a stable urging force, and to effectively exert the urging force in a direction in which the upper sides of the front surface portion and the rear surface portion are separated from each other. .

  It further includes a linear seam in which the side surface portion and the inner lining are sewn along the vicinity of the portion where the outer contour lines of the both end portions of the spring member in the curved state in the side surface portion are arranged. May be. In this configuration, both ends of the spring member are positioned so as to prevent the spring member from opening too far beyond the optimal curved shape, and preventing the spring member from shifting laterally beyond the optimal position. Can do.

  The bottom portion may be flat, and the side portions on both the left and right sides may be formed such that the length in the vertical direction is shorter than 1.6 times the length of the bottom side. In this configuration, since the bottom surface portion is flat, the pouch can be stably made independent. Furthermore, since the length in the vertical direction of the side portions on both the left and right sides is shorter than 1.6 times the length of the bottom side, the center of gravity of the pouch does not become too high. The pouch can be made stable and independent.

  The upper side of the side part may be formed longer than the bottom side of the side part. In this configuration, the length of the opening / closing portion in the front-rear direction is larger than that of the bottom surface portion, so that the opening / closing portion is fully opened and can easily be seen to the back of the storage space, so that the stored items can be easily taken in and out.

  The upper side of the side surface portion may have a shape curved concavely toward the bottom side of the side surface portion. In this configuration, when the opening / closing part is fully opened, the opening / closing part can be shown more widely, and therefore it is easy to put in and out the stored items. In addition, when the opening / closing part is closed, the upper side of the side part may be folded in the middle and projecting outward, but in that case, the amount of the projecting can be suppressed, so the pouch when the opening / closing part is closed The length in the left-right direction can be stored compactly, and the appearance of the pouch when closed is beautiful.

  The left and right sides of each of the front surface portion and the rear surface portion may be inclined inward in the opposing direction of the left and right sides from bottom to top. In this configuration, when the opening / closing part is closed, the upper side of the side part may be folded in the middle and projecting outward, but in that case, the amount of projecting can be suppressed, so when the opening / closing part is closed The length of the pouch in the left-right direction can be stored compactly, and the appearance of the pouch when it is closed is also beautiful.

  As described above, according to the present invention, it is possible to provide a pouch that is easy to use without causing any inconvenience in taking out stored items and closing the opening and closing part, as well as opening and closing the opening and closing part.

  As shown in FIGS. 1, 2, and 3, the pouch 1 includes a front surface portion 3, a rear surface portion 4, left and right side surfaces 5 and 6, and a bottom surface portion 7 surrounding the storage space S and the bottom side, The upper side of each of the front surface portion 3, the rear surface portion 4, and the left and right side surface portions 5, 6 forms an opening / closing portion 8, and the opening / closing portion 8 is a pouch that is opened and closed by a fastener 9.

  As an example of the dimensions of the pouch 1, the length in the left-right direction is about 180 mm, the length in the up-down direction is about 100 mm, and the length in the front-rear direction is about 80 mm. The opening / closing part 8 is a pouch that is fully opened automatically by removing the fastener 9.

  The front surface portion 3 and the rear surface portion 4 have the same shape and the same size as each other and have a trapezoidal shape. The left and right sides of each of the front surface portion 3 and the rear surface portion 4 are slightly inclined inward in the opposing direction of the left and right sides. The left and right side portions 5 and 6 have the same shape and the same size and are substantially inverted trapezoidal in front view. Specifically, the side portions 5 and 6 on the left and right sides are formed such that the length of the top side in the front-rear direction is 1.5 to 1.6 times longer than the length of the bottom side in the front-rear direction. Is slightly inclined outward in the opposing direction, and the upper side has a shape that is concavely curved toward the bottom side as a whole, and the corners on both the front and rear sides of the lower part are rounded. The bottom surface portion 7 has a rectangular shape in plan view, and the length in the longitudinal direction (that is, the left-right direction) is the same as the length of the bottom sides of the front surface portion 3 and the rear surface portion 4, and the short direction (that is, the front-rear direction). Is formed to have the same length as that of the bottom sides of the side portions 5 and 6 on the left and right sides.

  The front surface portion 3, the rear surface portion 4, the side surface portions 5 and 6 on the left and right sides, and the bottom surface portion 7 are formed of, for example, a thick woven fabric (for example, a hickory fabric) made of cotton. The bottom side of the front surface portion 3 is sewn to the front side of the bottom surface portion 7, and the bottom side of the rear surface portion 4 is sewn to the rear side of the bottom surface portion 7. And the front side, bottom side, and rear side of the left side surface part 5 are respectively sewn to the left side of the front surface part 3, the left side of the bottom surface part 7, and the left side of the rear surface part 4 via the high pins 10, respectively. The front side, the bottom side, and the rear side of the right side surface portion 6 are sewn to the right side of the front surface portion 3, the right side of the bottom surface portion 7, and the right side of the rear surface portion 4 via high pins 11, respectively. Each of the high pins 10 and 11 is formed of, for example, a thick woven fabric made of cotton (for example, denim fabric).

  A lining 12 is disposed inside each of the front surface portion 3, the rear surface portion 4, the side surface portions 5 and 6 on the left and right sides, and the bottom surface portion 7. The lining 12 is made of a cloth made of synthetic fibers such as nylon. As shown in FIG. 4, the lining 12 includes a lining portion 121 disposed on the back side of the front surface portion 3, the rear surface portion 4 and the bottom surface portion 7, a lining portion 122 disposed on the back side of the left side surface portion 5, and a right side surface. It is comprised with the lining part 123 arrange | positioned on the back side of the part 6. FIG.

  The lining portion 121 includes a front surface region 121 a disposed on the back side of the front surface portion 3, a rear surface region 121 b disposed on the back surface of the rear surface portion 4, and a bottom surface region 121 c disposed on the inner side of the bottom surface portion 7. And the same shape and size as the whole of the front surface portion 3, the rear surface portion 4 and the bottom surface portion 7 sewn as described above. Each of the lining parts 122 and 123 has the same shape and size as the side parts 5 and 6 on both the left and right sides (see FIG. 4).

  The left side of the lining portion 121 is sewn to the front side, the bottom side, and the rear side of the lining portion 122 via the high pins 14, and the right side of the lining portion 121 is the front of the lining portion 123 via the high pins (not shown). It is sewn to the side, bottom and back. Each of the high pin 14 and the high pin (not shown) is formed of the same kind of fabric as that of the lining 12, for example.

  The high pin 14 is sewn to the high pin 10, and the high pin (not shown) is sewn to the high pin 11. Thereby, the front surface region 121a, the rear surface region 121b, and the bottom surface region 121c of the lining portion 121 are fixed to the inside of the front surface portion 3, the rear surface portion 4, and the bottom surface portion 7, respectively, and the lining portions 122 and 123 are respectively left and right sides. Are fixed to the inside of the side portions 5 and 6. A slender core material having flexibility is accommodated in the high pin 14 and the high pin (not shown). Thereby, it can suppress that the outline of the side parts 5 and 6 on both right and left sides is out of shape, and the appearance of the pouch 1 can be made beautiful.

  One inner pocket 18 is provided on the inner lining 12 of the front surface portion 3 (that is, the front surface region 121a). For this reason, an inner pocket forming fabric 181 for forming the inner pocket 18 is sewn inside the front surface region 121a. The inner pocket forming fabric 181 is, for example, the same type of fabric as the lining 12, and the length in the left-right direction is formed to be the same as the length in the left-right direction of the front surface region 121a. It is shorter than the length in the direction. The inner pocket forming fabric 181 is sewn to the left and right sides and the bottom side of the front surface region 121a, with the upper side shifted from the upper side of the front surface region 121a and shifted to the lower side.

  Further, two inner pockets 19 are provided on the inner lining 12 (that is, the rear surface region 121b) inside the rear surface portion 4. Therefore, an inner pocket forming fabric 191 for forming the inner pocket 19 is sewn inside the rear surface region 121b. The inner pocket forming fabric 191 is, for example, the same type of fabric as the lining 12, and the length in the left-right direction is longer than the length in the left-right direction of the rear surface region 121b, and the length in the vertical direction is the rear surface region 121b. It is shorter than the length in the vertical direction.

  The inner pocket forming fabric 191 is adjusted to the same length as the length in the left-right direction of the rear surface region 121b by frog-folding the central portion in the left-right direction along the vertical direction, and the upper side is the rear surface portion. The left and right sides and the bottom side are sewn to the left and right sides and the bottom side of the rear surface region 121b, respectively, and the center of the frog fold portion is along the vertical direction in a state where it is shifted downward from the upper side of the region 121b. It is sewn to the rear surface area 121b. Two storage pockets 19 are formed by sewing the center of the frog folding portion to the rear surface region 121b along the vertical direction.

  A core material (not shown) for maintaining the flatness of the bottom surface portion 7 is disposed between the bottom surface portion 7 and the inner lining 12 (that is, the bottom surface region 121c). This core material is a sheet-like member having moderate elasticity and flexibility, and is, for example, a foamed resin such as bell polen or cardboard. The core material has the same shape and size as the bottom surface portion 7, and is sewn or bonded to the upper surface of the bottom surface portion 7, for example.

  In order to beautify the appearance of the pouch 1, for example, an edge cloth 17 is provided on the periphery of the opening / closing part 8 (that is, the upper side edge of each of the front surface part 3, the rear surface part 4, and the left and right side surface parts 5 and 6). Sewn. The edge cloth 17 is formed in the shape of an elongate belt, for example, by a thick woven fabric made of cotton. The edge cloth 17 is mountain-folded in the middle of the short side direction, with the peripheral edge of the opening / closing part 8 and the edge on the upper side of each lining part 121, 122, 123 sandwiched inside the mountain fold, The entire periphery of the periphery of the opening / closing part 8 is sewn.

  The fastener 9 is a slide fastener. The fastener 9 is composed of a pair of elements 9a and 9b provided on the periphery of the opening / closing part 8, and a slider 9c movable along the pair of elements 9a and 9b. One element 9a is sewn across the front half of the periphery of the opening / closing part 8 (that is, the front half of the upper edge of the side parts 5 and 6 on the left and right sides and the entire upper edge of the front face 3). The other element 9b extends over the rear half of the periphery of the opening / closing portion 8 (that is, the rear half of the upper side edge of the left and right side portions 5 and 6 and the entire upper side edge of the rear surface portion 4). Sewn. Thereby, the opening / closing part 8 can be opened and closed in the front-rear direction of the pouch 1. Note that both ends of the pair of elements 9a and 9b are extended so as to protrude to the outside of the side portions 5 and 6 on the left and right sides, respectively.

  The pouch 1 is further provided with a spring member 20 that is disposed outside the lining 12 and biases the upper sides of each of the front surface portion 3 and the rear surface portion 4 in a direction away from each other. Specifically, the spring member 20 is disposed between the side portions 5 and 6 on the left and right sides and the inner lining 12 (lining portions 122 and 123).

  The spring member 20 is a metal bar-like coil spring that is in close contact with the line when there is no load. If an example of the dimensions is given, the natural length is 1 of the length of the bottom of the side portions 5 and 6 on the left and right sides. It is formed to a length of about 5 times (for example, 1.4 times to 1.6 times), an outer diameter is formed to a thickness of 3 mm to 4 mm, and a wire diameter is 0.8 mm to 1.2 mm. Is formed. The spring member 20 is elastically deformed so that the spring member 20 is bent in a substantially V shape with the opening / closing portion 8 open (that is, both ends are directed upward and the central portion is curved relatively shallowly and protrudes downward). Both end portions are disposed in the vicinity of both ends of the upper sides of the side surface portions 5 and 6, and the curved portion is disposed in the vicinity of the center in the vertical direction of the side surface portions 5 and 6.

  In this way, the spring member 20 is elastically deformed and arranged so as to be bent in a substantially V shape with the opening / closing portion 8 open (that is, in an optimal bending state), so that the opening / closing portion 8 is closed. In addition, the spring member 20 can be prevented from exceeding the elastic limit, and a stable urging force can be exerted permanently when the opening / closing part 8 is opened. Since the curved portion of the spring member 20 is disposed near the center in the vertical direction of the side surface portions 5 and 6 (that is, the curved portion of the spring member 20 is disposed at an optimal position), the spring member 20 is prevented from being lowered too much. Thus, both end portions of the spring member 20 can be arranged near both end portions of the upper sides of the side surface portions 5 and 6 in a state where the spring member 20 is bent in a substantially V shape. Further, since both end portions of the spring member 20 are disposed near both ends of the upper sides of the side surface portions 5 and 6 (that is, both end portions of the spring member 20 are disposed at optimum positions), the biasing force of the spring member 20 is opened and closed. In order to open the part 8, it can be exhibited effectively.

  The spring member 20 has a linear shape when no load is applied (solid line in FIG. 5). For this reason, the spring member 20 is disposed between the side portions 5 and 6 on the left and right sides and the inner lining 12 (that is, the elastic member 20 is elastically deformed so as to be curved (two-dot chain line in FIG. 5)). ), The upper side of each of the front surface portion 3 and the rear surface portion 4 is urged away from each other by an elastic return force that attempts to return to a linear state.

  Further, seams 22, 23, and 24 for positioning the spring member 20 are provided on the side surfaces 5 and 6 on the left and right sides, respectively, so as to maintain the above-described optimal curved state and to be disposed at the optimal position. It has been.

  The seam 22 is a curved line-shaped seam, and along the vicinity of the portion where the concave contour line of the spring member 20 in the curved state in the side surface portions 5 and 6 is disposed, the side surface portions 5 and 6 and the inner lining 12 ( That is, the lining parts 121, 122) are sewn together. As a result, the spring member 20 is bent too much inward from the optimum curved state, and the spring member 20 is shifted too much to the concave side of the spring member 20 (that is, above the side portions 5 and 6) from the optimum position. Therefore, it is possible to effectively exert the urging force of the spring member 20 in the direction in which the upper sides of the front surface portion 3 and the rear surface portion 4 are separated from each other.

  The seam 23 is a linear seam, and the side portions 5 and 6 and the inner sides of the side portions 5 and 6 are disposed along the vicinity of the portions where the outer contour lines of the both ends of the curved spring member 20 in the side portions 5 and 6 are arranged. The lining 12 (that is, the lining portions 121 and 122) is sewn. As a result, the spring member 20 is excessively opened outward from the optimal curved state, and the spring member 20 is displaced from the optimal position in the lateral direction of the side surfaces 5 and 6 (that is, the front and rear direction of the pouch 1). This can also prevent the biasing force of the spring member 20 from being exerted effectively in the direction in which the upper sides of the front surface portion 3 and the rear surface portion 4 are separated from each other.

  Both end portions of the spring member 20 are formed into a bag shape by a seam 22, a seam 23, and a seam 25 (see FIG. 3) when the edge cloth 17 is sewn to the upper edge of the side surfaces 5 and 6. Also, the seam 25 prevents the spring member 20 from being displaced too far from the optimum position to the concave side of the spring member 20.

  The seam 24 is in the shape of a horizontal line and passes, for example, between the left and right sides of the side portions 5 and 6 so as to pass near the portion where the convex vertex of the curved portion of the spring member 20 in the curved state on the side portions 5 and 6 is disposed. The side portions 5 and 6 and the inner lining 12 (that is, the lining portions 121 and 122) are sewn. Thereby, it can prevent that the spring member 20 shift | deviates to the convex side of the spring member 20 from the optimal position, and also by this, the upper side of each of the front surface part 3 and the rear surface part 4 spaces apart the urging | biasing force of the spring member 20. It can be exhibited effectively in the direction.

  As shown in FIGS. 6 and 7, the pouch 1 configured as described above is fixed by the urging force of the spring member 20 even when nothing is put in the storage space S when the opening / closing part 8 is closed. It is kept in a state of tension. Even if it is inflated, if it is in a state where nothing is contained, it is reduced by being pushed, so it does not take up space unnecessarily.

  Moreover, since the bottom face part 7 is flat, the pouch 1 can be stably made to stand by itself. Moreover, since the lengths of the side portions 5 and 6 on the left and right sides are shorter than 1.6 times the length of the bottom side, the center of gravity of the pouch 1 does not become too high. The pouch can be made stable and independent. Furthermore, since the flatness of the bottom surface portion 7 is secured by the core material, the flatness of the flat surface portion 7 is not easily deformed, and even if the pouch 1 is used for a long time, the stable independence can be secured.

  Furthermore, in the state where the opening / closing part 8 is closed, the upper sides of the side parts 5 and 6 may be folded in the middle and project outward. In this case, the upper sides of the side parts 5 and 6 are Since it has a concavely curved shape on the bottom side, its overhanging amount can be suppressed, whereby the length of the pouch 1 in the left-right direction when the opening / closing part 8 is closed can be compactly accommodated and closed. The appearance of the pouch 1 is also beautiful. Such a compact and beautiful appearance of the pouch 1 is also obtained by the fact that the left and right sides of each of the front surface portion 3 and the rear surface portion 4 are inclined inward in the opposing direction of the left and right sides from the bottom to the top. It is done.

  As shown in FIGS. 1, 2, and 3, when opening the opening / closing portion 8, the slider 9 c of the fastener 9 is simply slid in the direction to open the opening / closing portion 8, and is opened / closed by the biasing force of the spring member 20. Since the part 8 can be fully opened, the opening / closing part 8 is easy to open. Furthermore, since the fully open state is maintained by the biasing force of the spring member 20, the stored item can be easily taken out.

  Furthermore, in the fully opened state of the opening / closing part 8, the upper sides of the side parts 5, 6 are formed 1.5 times to 1.6 times longer than the bottoms of the side parts 5, 6, so It is easy to do and it is easy to put in and out the stored items. In addition, when it is shorter than 1.5 times, the effect of facilitating visual recognition to the back of the storage space S may not be sufficiently exhibited. When it is longer than 1.6 times, the balance before and after the pouch 1 may be reduced. May be unstable, so 1.5 to 1.6 times is optimal. Furthermore, since the upper sides of the side surface parts 5 and 6 are concavely curved toward the bottom side of the side surface parts 5 and 6, the opening / closing part 8 can be shown wider, and this also facilitates the taking in and out of the stored items. Therefore, even if a variety of items such as coins are stored in the pouch 1, it is very easy to select and take out.

  In addition, since the spring member 20 is disposed outside the lining 12, that is, since the spring member 20 is not exposed in the storage space S, the stored item may sink under the spring member 20 and be difficult to take out. It is possible to prevent the inconvenience that the opening / closing part 8 is difficult to close. For this reason, it becomes a very easy-to-use pouch.

  Further, since the spring member 20 is disposed between the side surface portions 5 and 6 and the inner lining 12 thereof, that is, the spring member 20 is disposed in a portion that is not touched so much in the pouch 1, The spring member 20 can be provided without impairing the touch feeling of 1. Further, since the spring member 20 is disposed between the side surface portions 5 and 6 and the inner lining 12 thereof, the central portion of each of the front and rear sides of the opening / closing portion 8 by the biasing force of the spring member 20. Therefore, the contour of the opening / closing part 8 in the fully opened state can be maintained in a substantially rectangular state, and the appearance of the pouch 1 is beautiful.

  Furthermore, since the spring member 20 is rod-shaped, even if the spring member 20 is disposed between the side portions 5 and 6 and the inner lining 12 thereof, the swelling of the side portions 5 and 6 by the spring member 20 is suppressed. Therefore, it is difficult to understand that the spring member 20 is arranged in appearance, and this also makes the appearance of the pouch 1 beautiful. Further, since the spring member 20 is elastically deformed so that both end portions face upward and the central portion is curved and protrudes downward, the touch comfort and the appearance of the pouch 1 are ensured as described above. However, the urging force of the spring member 20 can be sufficiently exerted.

  In addition, since the spring member 20 is a coil spring that is in close contact with the line when there is no load, the contact area between the spring member 20 and the side surface portions 5, 6 and the lining 12 can be reduced, and the frictional resistance can be reduced. When the spring member 20 opens the opening / closing part 8, the urging force of the spring member 20 can be effectively exerted to open the opening / closing part 8 without being weakened by frictional resistance.

  Furthermore, since the spring member 20 has a rod shape with an outer diameter of 3 mm to 4 mm, that is, is formed to be relatively thin, the spring member 20 is disposed between the side surface portions 5 and 6 and the inner lining 12. However, the swelling of the side surface parts 5 and 6 by the spring member 20 can be suppressed, and it can be difficult to understand that the spring member 20 is arranged.

  Further, since the spring member 20 is a coil spring having a wire diameter of 0.8 mm to 1.2 mm, the spring member 20 is a coil that is formed relatively thin (that is, having a small outer diameter) while ensuring a biasing force. A spring can be used. When the wire diameter is less than 0.8 mm, it is difficult to ensure a sufficient urging force, and when the wire diameter is larger than 1.2 mm, it is difficult to sufficiently reduce the outer diameter of the coil spring.

  Furthermore, since the spring member 20 is made of metal, a sufficient urging force for opening the opening / closing part 8 can be secured even if the spring member 20 is formed relatively thin. The metal spring member 20 has good durability and can be used well over a long period of time. The good durability of the spring member 20 can also be obtained by holding the spring member 20 (that is, fixing the arrangement) by sewing. That is, if the adhesive is used to hold the spring member 20, the adhesive part easily comes off with aging and deformation, but since it is sewn, the holding state can be maintained as long as the seams 22, 23, 24 are not removed. .

  The above configuration is one configuration for carrying out the present invention, and other configurations can also be adopted. For example, the spring member 20 may be formed of a material other than metal, such as a resin tube, instead of a metal coil spring, and may be changed to one having a form other than the coil spring. Further, instead of disposing the spring member 20 between the side surface portions 5 and 6 and the inner lining 12 thereof, the inner lining 12 and the inner surface of the front surface portion 3, the bottom surface portion 7 and the rear surface portion 4 are arranged. You may arrange | position between. Further, the fastener 9 may be replaced with a slide fastener, and may be changed to other opening / closing means such as a gusset base.

  Further, the type of fabric of the front surface portion 3, the rear surface portion 4, the side surface portions 5, 6 and the bottom surface portion 7 may be changed to a resin-made sheet material such as a synthetic fiber or a vinyl sheet in place of the thick fabric of cotton material. . Further, although the spring member 20 is curved relatively shallowly in a substantially V shape, the spring member 20 is not limited to a substantially V shape, and may be curved relatively deeply, for example, in a substantially U shape. Further, the shapes of the seams 22, 23, and 24 are curved, linear, and horizontal, respectively. However, the shape is not limited to such shapes, and the seams 22, 23, and 24 exhibit the above-described effects. Any shape is possible as long as it is possible.

  In addition, the dimension and shape of the above-mentioned pouch 1, and the length in the front-rear direction and the length in the up-down direction of the upper side of the side portions 5 and 6 are merely guidelines, and are not limited to such dimensions and shapes. Any size and shape may be used as long as the above-described effects can be exhibited.
