  However, in the case of the waterproof case disclosed in Patent Document 1, since the air chamber communicates with the surroundings of the article storage chamber and on the front and back, the air with respect to the air storage chamber can be taken in and out only by opening and closing the air valve. For example, there has been a trouble that the air must be forcibly introduced artificially, such as when a known floating ring is inflated when necessary.

  Further, in the case of the waterproof case disclosed in Patent Document 2, in order to take air into the air storage chamber when necessary while keeping the usage form in which the article is stored in the article storage chamber, an artificial air valve is used as in Patent Document 1. If air is not forcedly introduced, sufficient air cannot be taken in, and there is a problem that the stored item cannot be pressed and held on one side of the case body.

  The technique disclosed in Patent Document 1 has an opening on the upper edge separately from the air valve, and air can be taken into the air storage chamber from here, but the sealing performance is low. There is a problem that air easily leaks from the air storage chamber and that it is difficult to sufficiently take in air simply by opening it. In addition, when the amount of air taken in is the same, if the surface area of the stored article is narrower than the surface area of the waterproof case, the weight load is concentrated particularly in the case of a stored article having a weight such as a portable communication terminal. Therefore, there is also a problem that the floating property cannot be secured.

  An object of the present invention is to provide a waterproof case that has high sealing performance and can take in sufficient air only by opening the opening, and can ensure floating properties.

  In order to achieve the above object, according to the first aspect of the present invention, a part of the peripheral edge portions of the pair of soft waterproof resin sheets is formed as a linear opening portion, and the remaining portion is a second portion for each sheet. One of the peripheral portions of the air storage chamber as one joint portion and one of the pair of soft waterproof resin sheets is formed in a linear shape parallel to the opening. Opposite the pair of flexible waterproof resin sheets along the edge of the opening and across the entire width as an article intake and the remaining part as a second joint to one soft waterproof resin sheet A pair of elastically deformable first thin opening / closing pieces and a flexible transparent waterproof resin sheet and one flexible waterproof resin sheet that are disposed opposite to each other along the edge of the article intake and across the entire width. Pair of second thin open / close pieces A male and female belt-shaped surface fastener disposed on the other surface of the pair of soft waterproof resin sheets and spaced apart from the opening in parallel to the edge of the opening and across the entire width; and a soft transparent waterproof The male and female belt-like surface fasteners arranged on the surface of the resin sheet and spaced from the male and female belt-like surface fasteners and the article intake port in parallel with the edge of the article intake port and across the entire width, The male and female belt-like surface fasteners and the male and female belt-like surface fasteners take in outside air into the air storage chamber by elastically deforming the pair of first thin opening and closing pieces to open the openings, and the pair of second thin wall opening and closing members. After the article is elastically deformed to open the article intake, the article is stored in the article storage chamber, and the opening and the article intake are directed toward the storage depth direction orthogonal to the direction in which the opening extends. The when each sheet is folded several times so as to engulf the inside, and arranged at a position to engage each other, but.

  In the device according to claim 2, the separation distance in the storage depth direction from the opening to the one band-shaped surface fastener of the male and female including the pair of first thin opening and closing pieces, and the storage depth direction of the band-shaped surface fastener of the male and female The distance from the male and female belt-shaped surface fasteners to the storage depth direction of the male and female belt-shaped surface fasteners and the height of the male and female belt-shaped surface fasteners to the storage depth direction are the same. It is.

  In the invention described in claim 3, the article intake and the second thin opening / closing piece are located within the height range of the male and female belt-like surface fasteners in the storage depth direction.

  In the invention according to claim 4, the pair of flexible waterproof resin sheets in the male and female strips are located inside the air storage chamber and spaced apart from the male and female belt-like surface fasteners in the storage depth direction. It is provided with a pair of elastically deformable third thin opening / closing pieces that are arranged to face each other along the edge of the hook-and-loop fastener and span the entire width.

  In the invention according to claim 5, one of the pair of third thin opening / closing pieces is a metal thin sheet and the other is a magnet sheet.

According to the present invention, the air storage chamber and the article storage chamber are provided separately, and a pair of first thin opening / closing pieces that can be elastically deformed are provided at the opening of the air storage chamber. By simply deforming the opening and closing piece to open the opening, the outside air can be taken into the air storage chamber along with the sudden opening.
Further, if the elastic deformation of the pair of first thin opening / closing pieces is restored to the original state by the elastic force, the sealing performance can be ensured. Furthermore, when each sheet is bent a plurality of times so as to wind the opening and the article intake inward in the storage depth direction perpendicular to the direction in which the opening extends, the band-shaped surface fasteners of different sexes engage with each other. As a result, the volume of the air storage chamber can be reduced while further ensuring the sealing performance. As a result, the floatability can be ensured by bringing the surface area of the waterproof case closer to the surface area of the stored article.

  Thus, the sealing property is high, and sufficient air can be taken in only by the opening operation of the opening, and the floating property can be ensured.

  Further, when the sheets are bent a plurality of times so that the opening and the article intake are wound inward with respect to the height of the male and female belt-shaped surface fasteners in the storage depth direction, By evenly arranging so as to engage with each other, the bending work can be easily performed without providing a special broken line.

  Further, by placing the article intake and the second thin opening / closing piece within the range of the storage depth direction of the belt-like surface fastener of one of the male and female, the article can be easily taken in and out from the article intake. In addition, when the sheet is bent a plurality of times so as to wind the opening and the article intake inward, the article intake by the second thin opening and closing piece utilizing the thickness and cushioning property of the band-shaped surface fastener of the male and female. It is possible to improve the sealing performance.

  The pair of soft waterproof resin sheets 2 and 3 are the same in terms of material, and a colored transparent or colorless transparent sheet is used as necessary. As the pair of soft waterproof resin sheets 2 and 3, for example, substantially rectangular ones having some corners having an R shape are used.

  Here, the pair of soft waterproof resin sheets 2 and 3 are joined (first joined portion) by thermal welding or the like with the three sides except the one short side (upper side in the figure) as the peripheral portion.

  Thereby, a pair of soft waterproof resin sheets 2 and 3 form the bag-shaped air storage chamber 6 which makes the opening part 5 which has not joined one linear short side.

  The soft transparent waterproof resin sheet 4 uses a colorless and transparent sheet made of vinyl chloride so that the screen of the smartphone S as a stored item can be seen.

  The flexible transparent waterproof resin sheet 4 has the same width direction (left and right direction in FIG. 1) with respect to the pair of soft waterproof resin sheets 2 and 3, and the height direction (up and down direction in FIG. 1). A low, almost rectangular shape is used.

  Here, the soft transparent waterproof resin sheet 4 is located on one of the pair of soft waterproof resin sheets 2, 3, for example, the surface of the soft waterproof resin sheet 2, and is a straight line parallel to the opening 5. 3 sides excluding one short side (upper side in the figure) are joined to the one soft waterproof resin sheet 2 by heat welding or the like as a peripheral part (second joined part).

  In the present embodiment, the joining of the soft transparent waterproof resin sheet 4 is also used as a pair of soft waterproof resin sheets 2 and 3.

  As a result, the soft transparent waterproof resin sheet 4 and the one soft waterproof resin sheet 2 form a bag-shaped article storage chamber 8 that serves as an article intake 7 in which one short side of the straight line is not joined. ing.

  As described above, the waterproof case 1 has a part of the peripheral edge portions of the pair of soft waterproof resin sheets 2 and 3 as the linear opening portion 5 and the remaining portion as the first joint portion for the sheets. The air storage chamber 6 is positioned on one surface of the pair of soft waterproof resin sheets 2 and 3, and a part of the peripheral edge of the soft transparent waterproof resin sheet 4 is in a straight line parallel to the opening 5. And an article storage chamber 8 having the remaining portion as a second joint to the one soft waterproof resin sheet 2.

  As shown in FIG. 3, the pair of flexible waterproof resin sheets 2 and 3 are made of plastic sheets or the like on the inner surfaces with the air storage chamber 6 as a reference, along the edge of the opening 5 and across the entire width. A pair of first thin opening / closing pieces 9, 10 that are thin and elastically deformable are provided.

  The belt-like surface fastener 17 is fixed to the surface of the other soft waterproof resin sheet 3 with a double-sided tape or an adhesive (not shown).

  The band-shaped surface fastener 17 is located at a position away from the opening 5 in the height direction, that is, at a position away from the opening 5 by a predetermined distance in the storage depth direction orthogonal to the direction in which the edge of the opening 5 extends. It is parallel to the edge and spans the entire width.

  On the surface of the soft transparent waterproof resin sheet 4, the other band-shaped surface fastener 18 of the male and female is provided. The belt-like surface fastener 18 is fixed to the surface of the soft transparent waterproof resin sheet 4 with a double-sided tape or an adhesive (not shown).

  The belt-like surface fastener 18 is separated from the belt-like surface fastener 17 and the article intake 7 in the height direction, that is, separated by a predetermined distance toward the storage depth direction orthogonal to the direction in which the edge of the article intake 7 extends. In position, it is parallel to the edge of the article intake 7 and spans the entire width.

  As described above, the waterproof case 1 is arranged on the other surface of the pair of soft waterproof resin sheets 2 and 3 and at a position spaced from the opening 5 so as to be parallel to the edge of the opening 5 and span the entire width. One of the male and female belt-shaped surface fasteners 17 and the surface of the flexible transparent waterproof resin sheet 4 and spaced from the male and female belt-shaped surface fasteners 17 and the product intake port 7 and parallel to the edge of the product intake port 7 And the other band-shaped surface fastener 18 disposed so as to straddle the entire width.

  The pair of soft waterproof resin sheets 2 and 3 are thin and elastic such as a plastic sheet on the inner surfaces with the air storage chamber 6 as a reference, along the edge of the male and female belt-like surface fasteners 18 and across the entire width. A pair of deformable third thin opening / closing pieces 19 and 20 are provided.

  The third thin opening and closing pieces 19 and 20 are, for example, the edge portions of the contact sheets 21 and 22 that are high in the height direction of the third thin opening and closing pieces 19 and 20 by the same material as the pair of soft waterproof resin sheets 2 and 3. Are attached to the pair of soft waterproof resin sheets 2 and 3 by thermal welding.

  The reason why the contact sheets 21 and 22 are made of the same material as that of the pair of soft waterproof resin sheets 2 and 3 is to secure the bonding property by heat welding and to ensure the elastic deformability of the third thin opening and closing pieces 19 and 20. It is.

  For example, the third thin opening / closing pieces 19 and 20 can be made of a metal thin sheet on one side and a magnet sheet on the other side.

  As described above, the waterproof case 1 is provided on the pair of soft waterproof resin sheets 2 and 3 in the air storage chamber 6 and at a position separated from the other band-shaped surface fastener 18 in the storage depth direction. A pair of elastically deformable third thin opening / closing pieces 19 and 20 are provided so as to face each other along the edge of the other band-shaped surface fastener 18 and to straddle the entire width.

  One of the pair of third thin opening / closing pieces 19 and 20 is a metal thin sheet, and the other is a magnet sheet.

  Here, as shown in FIG. 1, a separation distance T1 from the opening 5 to the one-sex strip-shaped surface fastener 17 including the pair of first thin opening / closing pieces 9, 10 and the strip-shaped surface of the both sexes. The height T2 of the fastener 17 in the storage depth direction, the separation distance T3 in the storage depth direction from the male and female belt-like surface fasteners 17 to the male and female belt-like surface fasteners 18, and the storage depth of the male and female belt-like surface fasteners 18. The height T4 in the direction is substantially the same.

  In addition, the article intake 7 and the second thin opening / closing pieces 13 and 14 are positioned within the range of the height T2 in the storage depth direction of the band-like surface fastener 17 of one male and one female.

  Next, the operation of the pair of first thin opening / closing pieces 9, 10, the pair of second thin opening / closing pieces 13, 14, and the pair of third thin opening / closing pieces 19, 20 will be described.

  As shown in FIG. 4, the pair of first thin opening / closing pieces 9 and 10 and the pair of third thin opening / closing pieces 19 and 20 are both applied in the width direction by applying an external force that causes both ends in the width direction to approach each other. The opening 5 and the air storage chamber 6 are opened by being bent and deformed in a substantially U shape with the center at the maximum.

  At this time, the pair of first thin opening / closing pieces 9 and 10 and the pair of third thin opening / closing pieces 19 and 20 rapidly bend and deform as the external force increases, thereby opening the opening 5 and the air storage chamber 6. Thereby, outside air can be rapidly taken in toward the air storage chamber 6 from the opening 5.

  The pair of first thin opening / closing pieces 9 and 10 and the pair of third thin opening / closing pieces 19 and 20 return to the original state due to their own elasticity when the external force applied to both ends in the width direction is released, and the openings Close 5

  In addition, since a pair of 3rd thin opening-and-closing piece 19 and 20 is located in the middle part of the swelled state, it is difficult to return to the original state.

  As shown in FIG. 5, the pair of second thin opening / closing pieces 13, 14 is bent and deformed into a substantially U shape with the center in the width direction as a maximum by applying an external force that brings both ends in the width direction closer to each other. And the article intake 7 is opened.

  As a result, the smartphone S can be stored in the article storage chamber 8 from the article intake 7.

  At this time, the smartphone S has one softer side than the article intake 7 (user standard for vertical use) or below the article intake 7 (user standard for horizontal use). Since the waterproof waterproof resin sheet 2 is located, this one soft waterproof resin sheet 2 can be used as a guide wall.

  In a state in which outside air is taken into such an air storage chamber 6 and the smartphone S is stored in the article storage chamber 8, more preferably, the sheets 2, 3 and 4 on the side where the opening 5 is located are bent multiple times. Thus, the belt-like surface fastener 17 and the belt-like surface fastener 18 may be engaged with each other.

  Specifically, as shown in FIG. 6, first, the openings 5 of the pair of soft waterproof resin sheets 2 and 3 are bent toward the side where the article intake 7 is provided.

  Next, as shown in FIG. 7, the pair of soft waterproof resin sheets 2 and 3 and the soft transparent waterproof resin sheet 4 are bent so as to enclose the opening 5 and the article intake 7.

  Further, as shown in FIG. 8, the belt-like surface fastener 17 and the belt-like surface fastener 18 are bent once more so as to engage with each other.

  Thus, the male and female belt-shaped surface fasteners 17 and the male and female belt-shaped surface fasteners 18 are formed in the air storage chamber 6 by elastically deforming the pair of first thin opening / closing pieces 9 and 10 to open the opening 5. While taking in external air and elastically deforming the pair of second thin opening and closing pieces 13 and 14 to open the article intake 7, the article (smartphone S) is accommodated in the article storage chamber 8, and the opening 5 extends. When the sheets 2, 3, and 4 are bent a plurality of times so as to wind the opening 5 and the article intake 7 inward in the storage depth direction orthogonal to the direction, they are arranged at positions that engage with each other. .

That is, the air storage chamber 6 and the article storage chamber 8 are provided separately, and the pair of first thin opening / closing pieces 9 and 10 that can be elastically deformed are provided in the opening 5 of the air storage chamber 6. By simply deforming the first thin opening and closing pieces 9 and 10 and opening the opening 5, the outside air can be taken into the air storage chamber 6 along with the sudden opening.
Further, if the elastic deformation of the pair of first thin opening / closing pieces 9 and 10 is restored to the original state by the elastic force, the sealing performance can be ensured. Further, when the sheets 2, 3 and 4 are bent a plurality of times so as to wind the opening 5 and the article intake 7 inward in the storage depth direction orthogonal to the direction in which the opening 5 extends, the sexes differ. When the band-shaped surface fasteners 17 and 18 are engaged with each other, the volume of the air storage chamber 6 can be reduced while further ensuring the sealing performance. As a result, the waterproof case is provided against the surface area of the smartphone S that is a storage article. Floatability can be ensured by bringing the surface area of 1 closer.

  Thus, the sealing property is high, and sufficient air can be taken in only by the opening operation of the opening, and the floating property can be ensured.

  Further, when the sheets 2, 3, and 4 are bent a plurality of times so that the opening 5 and the article intake port 7 are wound inward with reference to the height of the male and female belt-shaped surface fasteners 17 and 18 in the storage depth direction. In addition, since the belt-like surface fasteners 17 and 18 having different sexes are equally arranged so as to be engaged with each other, the bending work can be easily performed without providing a special fold line.

  In addition, since the article intake 7 and the second thin opening / closing pieces 13 and 14 are positioned within the height range of the male and female belt-like surface fasteners 17 in the storage depth direction, the smartphone S can be taken in and out of the article intake 7. When the sheets 2, 3 and 4 are bent a plurality of times so that the opening 5 and the article intake 7 are wound inside, the thickness of the belt-like surface fastener 17 on one side of the male and female and The sealing property of the article intake 7 by the second thin opening and closing pieces 13 and 14 can be improved by utilizing the cushioning property.

  Further, by providing a pair of third thin opening / closing pieces 19, 20 that can be elastically deformed inside the air storage chamber 6, simultaneously with the opening operation of the opening 5 by the first thin opening / closing pieces 9, 10, The inside can be forcibly expanded, and the intake of air into the air storage chamber 6 can be further ensured.

  Furthermore, by configuring the pair of third thin opening / closing pieces 19 and 20 with a metal thin sheet and a magnet sheet, the volume of the air storage chamber 6 can be further reduced and adhesion can be ensured.

  By the way, the waterproof case 1 of this invention is not limited to the box mentioned above. For example, in the above-described embodiment, each of the sheets 2, 3, and 4 is configured as a rectangle, but the shape and the joint are not limited.
