This invention makes it a subject to provide the storage body provided with the new structure which prevented the fluid flowing out from the storage part carelessly.

The storage body of the present invention includes a sealable storage portion and a seat valve provided inside or outside the storage portion. The seat valve is composed of a plurality of seats including at least two front and rear seats, a valve portion provided on a distal end side of the seat valve, and a fixing portion provided on a proximal end side of the seat valve; The valve portion includes a valve passage formed between the front and rear seats. The valve passage includes a fluid outflow inlet at a base end and a distal end, and controls the flow of the fluid between the outflow inlets by close contact and separation of the seat, thereby allowing the fluid to flow in and out of the housing portion. It is intended to regulate.

The front and rear seats are bent by a bent portion between the valve portion and the fixed portion, and the fixed portion includes a fixed seal portion that fixes the front and rear seats to the accommodating portion. The front and rear seats are joined in a tubular shape by a valve seal portion at the valve portion, are not joined to each other at the fixed portion, and are fixed to the housing portion by a fixed seal portion in an opened state. In the fixed seal portion, a semi-annular seal portion is formed on the inner surface side of each of the front and rear sheets, and has an annular shape with a boundary between the front and rear sheets interposed therebetween. Open to the boundary. The accommodating portion includes an opening that connects the inside and the outside of the accommodating portion, and the outflow inlet and the opening at the base end are located on the inner side of the annular shape, so that the distal end of the seat valve The outflow inlet and the outside of the opening of the housing portion are electrically connected via the valve portion.

In the storage body of the present invention, the front and rear seats are bent from the bent portion to either the front or rear, the valve portion is detachably temporarily fixed along the storage portion, and the temporary fixing is removed. The fixing part and the valve part may be T-shaped in a side view.

Moreover, the said accommodating part is equipped with an accommodating part main body and a cover body, and while being provided with the said opening part, the said fixing | fixed part may be fixed to the said cover body.

In the present invention, the front, rear, upper, lower, left and right only indicate a relative positional relationship, and should not be understood as specifying an absolute position.

The present invention has been able to provide a storage body having a new configuration that has not been conventionally provided. Thereby, the following effects are selectively exhibited according to various storage bodies.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a storage body according to the first embodiment. This storage body includes a storage portion 11 and a seat valve 21, and has a bottomed cylindrical cup-shaped storage portion 11, And a lid 13 detachably attached to the open end. An opening 14 is formed in the flat portion of the lid 13. In this example, it is appropriate to use a material having rigidity such as hard plastic, paper, metal, earthenware, or the like for the accommodating portion 11 and the lid 13. The lid body 13 is most desirable to have a high sealing property and can be easily attached / detached, such as forced fitting or fixing by a screw lid type, but even a non-detachable or a low sealing property, Can be implemented. Moreover, although illustration is abbreviate | omitted, a highly flexible thing, such as a bag, may be sufficient as a storage body, and what is necessary is just to be able to accommodate fluids, such as air, water, and a chemical | medical agent inside.

The storage body can be used in various ways. For example, it can store various liquids such as drinking water, and can suck out the liquid by inserting a straw (not shown) from the opening 14. It can be implemented as a container. Moreover, powder juice and a chemical | medical agent are previously accommodated in the accommodating part 11, and it can also be sucked out with a straw similarly to said example, adding water at the time of taking. Alternatively, a volatile substance such as a fragrance may be stored, and the internal gas may be allowed to flow out from the opening 14 when necessary.

As shown in FIG. 2A, the seat valve 21 includes a front seat 22 and a rear seat 23, and the whole has a substantially T-shape in side view. The front sheet 22 and the rear sheet 23 are composed of a sheet made of a soft synthetic resin that can be adhered and separated, or a sheet made of a composite material of another material such as a soft synthetic resin film and a metal foil. When the front seat 22 and the rear seat 23 are in close contact with each other, the flow of the fluid is blocked, and the valve seat 33 having a valve function that allows the fluid to pass by separating the front seat 22 is formed. Further, as shown in FIG. 2B, a valve seat 24 may be provided between the front seat 22 and the rear seat 23. In this case, the base end side of the valve seat 24 is bent together with one of the front seat 22 and the rear seat 23 (the front seat 22 in the example in the figure) and fixed to the lid 13, and the other that is not overlapped. A valve passage 33 is formed between the other seat (the rear seat 23 in the example shown in the figure) to pass and block the fluid. Note that the valve seat 24 may be disposed only in the region of the valve passage 33.

The front seat 22 and the rear seat 23 are formed in a cylindrical shape by joining both sides of the front seat 22 and the rear seat 23 by a valve seal portion 32, but one of the sheets is folded into two. You may make it make a cylinder shape by joining only a side. A portion of the seat valve 21 joined in a cylindrical shape is a valve portion 31, which has an outlet 35 at the tip and an inlet 34 at the base.

The base end side of the seat valve 21 is a fixing portion 41 where the front seat 22 and the rear seat 23 are not joined to each other. A crease line 27 is formed in the front seat 22 and the rear seat 23 between the valve portion 31 and the fixed portion 41, and the front seat 22 and the rear seat 23 extend in directions opposite to each other toward the proximal end. 21 has a T-shape as viewed from the side. The above-described inlet 34 is opened at the boundary 26 between the front sheet 22 and the rear sheet 23.

The fixing portion 41 is fixed to the inner surface side of the lid body 13 by a fixing seal portion 42. This fixing can be performed by melting or an adhesive. As shown in FIG. 3, the fixed seal portion 42 has a semi-annular seal portion 43 formed on the front seat 22 and the rear seat 23, and has an annular shape as a whole. The inflow port 34 is opened inside the annular shape, and the opening 14 of the lid 13 is located. Note that the entire front surfaces of the front sheet 22 and the rear sheet 23 forming the fixing portion 41 can be bonded to the lid 13 in an annular shape. However, when the diameter of the straw to be inserted is large, it is desirable to leave a space 44 between the fixed seal portion 42 and the inflow port 34. The shape of the fixed seal portion 42 may be other polygons, a circle, an ellipse, or the like in addition to a square shape, and the shape of the semi-annular seal portion 43 between the front seat 22 and the rear seat 23 is symmetrical. It does not have to be a shape. In FIG. 3, the fixed seal portion 42 is provided along the outer edges of the front seat 22 and the rear seat 23 in the fixed portion 41, but the fixed seal portion 42 is provided inside the outer edges of the front seat 22 and the rear seat 23. It is also possible that the planar shapes of the two do not need to match.

With the above configuration, the opening 14 is electrically connected to the inside of the accommodating portion 11 through the space formed by the annular fixed seal portion 42 of the fixing portion 41, the inlet 34, the valve passage 33, and the outlet 35. When the fluid is allowed to flow into the accommodating portion 11, the valve passage 33 is opened by the fluid flowing in from the inlet 34 by applying pressure to the fluid from the outside of the opening 14 to forcibly flow in, and the outlet 35. Flows into the accommodating portion 11. Although not shown, a tubular body such as a straw may be inserted into the valve passage 33 from the opening 14 to allow fluid to flow in.

By press-fitting the fluid and removing the straw, the front seat 22 and the rear seat 23 of the valve portion 31 are in close contact with each other, and the fluid in the housing portion 11 is suppressed from flowing out. Thereby, when the accommodating part 11 falls down or is carried around, it can prevent that an internal fluid flows out carelessly.

When it is desired to allow the internal fluid to flow out, a tubular body such as a straw may be inserted to form a flow path, or the lid body 13 may be removed.
As described above, the seat valve 21 is used in a state in which the fixing portion 41 is fixed to the inner surface of the lid body 13 and the valve portion 31 is suspended from the center thereof. The valve portion 31 may be temporarily fixed to the lid body 13 by the temporary fixing portion 28 (see FIG. 4A). The temporary fixing portion 28 may be one in which an adhesive is applied to the outside of the front sheet 22 or the rear sheet 23 or a separate adhesive tape is used, or a locking projection is provided on the lid 13. There may be.

An example of a method for fixing the seat valve 21 to the lid body 13 will be described with reference to FIG. The seat valve 21 is continuously manufactured and wound into a roll as necessary. A conventionally well-known method can be applied to the manufacturing method of the seat valve 21 itself. In that case, it is more industrially possible to bend the valve portion 31 along either the front seat 22 side or the rear seat 23 side of the fixing portion 41 (the front seat 22 side in FIG. 4A). This is advantageous for efficient manufacturing. In the case of winding in the form of a roll, it is easy to bend and wind along the roll, so that there is no hindrance to the subsequent processing (fixing to the lid 13), but more careful. When it is desired to temporarily fix, temporary fixing may be performed by the temporary fixing unit 28.

Next, when fixing to the lid 13 or before that, the sheet valve 21 is separated for each. The separated fixed portion 41 of the seat valve 21 is welded by heat sealing or ultrasonic waves along the lid body 13. At the time of welding, heat or sound waves may be applied from either the upper or lower side, but in this example, as shown in FIG. 4 (B), a heating device 51 is arranged on the lid 13 side (upper side in the figure) The fixed seal portion 42 is melted. At that time, by adjusting the heating temperature of the heating device 51, the front seat portions 22 folded in two are welded together, or the valve passage 23 between the front seat 22 and the rear seat 23 is welded. It can be prevented from being done. As shown in FIG. 4C, the heat-resistant ink 52 can be applied to at least one of the front sheets 22 folded in half, and further applied to the valve passage 33 as necessary. May be. However, when it is not desirable to use the heat-resistant ink 52, as shown in FIG. 4D, a laminate film having a multi-layer structure can be adopted for the front sheet 22 and the rear sheet 23. An easily weldable film 53 having a low melting temperature, such as polypropylene, is used on the inner surface of the front sheet 22 and the rear sheet 23, and hardly weldable, such as PET or polyamide, on the outer surface. By using the film 54, fusion between the front sheet 22 and the rear sheet 23 may be prevented.

The heat-resistant ink 52 and the hardly weldable film 54 are for preventing the fixing portion 41 and the valve portion 31 from being welded, and the valve portion 31 is overlapped on the fixing portion 41 by being folded into the minimum necessary number. What is necessary is just to form and arrange in at least any one of the valve part 31 and the fixing | fixed part 41 in the part which overlaps with the semi-annular seal part 43 of the side. It is sufficient that the heat-resistant ink 52 is printed only on a portion overlapping the semi-annular seal portion 43. However, it is desirable to print with thicker eyes than the semi-annular seal portion 43 with a little margin. Moreover, you may print the heat resistant ink 52 on the whole surface except a required welding location. Since it is disadvantageous in industrial production that the hardly weldable film 54 is disposed only in a portion overlapping with the semi-annular seal portion 43, as shown in FIG. 4 (E), the left side where the bent valve portion 31 overlaps is shown. What is necessary is just to arrange | position to the area | region of the same front-back width or more as the semi-annular seal part 43 or more, the same left-right length or more, or you may make it arrange | position to the whole surface.

As described above, the seat valve has been mainly used for controlling the flow of fluid into and out of the flexible bag body. However, according to the present invention, the seat valve can be widely used not only for the bag body but also for a rigid container. It was possible to expand the range of use. In addition, although illustration is abbreviate | omitted, the seat valve 12 can also be arrange | positioned on the outer side (namely, the outer side of a storage body) of the cover body 13. FIG. The seat valve 12 may be a check valve that allows the passage of fluid only in the direction in which the fluid flows out of the storage body, or a check valve that allows the passage of fluid only in the direction in which the fluid flows into the storage body. There may be.
