DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid container most suitable for filling various liquids such as sports drinks and fruit juice drinks.

[0002]

2. Description of the Related Art Conventionally, as a liquid container which is filled with various liquids such as sports drinks and fruit juice drinks and can be taken out as required, there is one disclosed in Japanese Utility Model Publication No. 21399/1990. The liquid container described in the publication includes a container main body made of a flexible sheet, and a cylindrical take-out device for taking out the liquid filled in the container main body, and the take-out device is provided with a conduit. The part is attached to the edge of the container body so that the part extends into the container body. Further, an opening through which the liquid in the container body 1 can flow is formed near the opening sealing portion of the container body in the conduit portion of the removal tool.

[0003] When the take-out device is used as a straw, the liquid is sucked up by closing the opening using the flexibility of the container body.

[0004]

However, in the case of using the dispensing tool as a straw, there is no problem in taking out the liquid in the above-mentioned liquid container. However, the container body is tilted and the opening of the dispensing tool is poured. When used as a mouth, since the container main body has flexibility, there is a risk that the container main body may close the opening, and there is a disadvantage that the liquid cannot be taken out reliably.

[0005] In particular, when the liquid is quickly taken out by pressing the container body, the above problem becomes remarkable because the deformation of the container body increases together with the outflow amount of the liquid.

[0006] The present invention has been made in view of the above-mentioned conventional problems, and it is apparent that the liquid can be rapidly and reliably taken out even when it is used as a spout. It is an object to provide a container for use.

[0007]

The technical measures taken by the present invention to solve the above-mentioned problems include a container body 1 made of a flexible sheet and a liquid filled in the container body 1. And a take-out device 3 for taking out the container body 1 so that the conduit portion 6 extends into the container body 1.
In the container for liquid attached to the edge 1a of the container, the removal tool 3 has an attachment portion 5 hermetically fixed to the edge 1a of the container body 1, and the conduit portion 6 is provided in the attachment portion 5. The passage gap 15 through which the liquid can flow is formed between the conduit portion 6 and the mounting portion 5.

[0008]

In the liquid container of the present invention, when the take-out device 3 is used as a straw, the liquid can be sucked up through the conduit portion 6 when the upper end of the take-out device 3 is sucked.

When the take-out device 3 is used as a spout, if the container body 1 is tilted or inverted so that the take-out device 3 faces downward, the liquid in the container body 1 passes through the gap 15 for circulation. Outflow. If the container body 1 is deformed by strongly pressing the container body 1 from both sides during the outflow of the liquid, even if the container body 1 is deformed, the flow gap 15 is formed between the mounting portion 5 having a rigid body and the conduit portion 6. Since it is provided between the container main body 1 and the non-deformed portion, there is no possibility that the container main body 1 will close the circulation gap 15, and the liquid can be quickly and reliably taken out.

[0010]

An embodiment of the present invention will be described below with reference to the drawings. 1 to 4 show one embodiment of the present invention,
In FIG. 1, reference numeral 1 denotes a container body in which a flexible sheet body is formed in a bag shape with an upper opening, and an edge 1a at an upper end of the container body 1 is filled in the container body 1. A take-out device 3 for taking out a liquid such as a sports drink or a fruit drink is provided. The material of the sheet is not particularly limited as long as the sheet has flexibility. For example, a laminated film of a synthetic resin film such as polyester or polyamide and an aluminum foil can improve the storage stability of the contents. Excellent and preferred. The innermost layer of the laminated film is formed from a heat-fusible resin.

The removal tool 3 has a mounting portion 5 which is simultaneously clamped when the edge 1a of the container body 1 is flatly sealed by heat fusion, and extends from the mounting portion 5 into the container body 1. The formed conduit portion 6 is integrally molded with a synthetic resin. Incidentally, the synthetic resin forming the take-out device 3 has heat-fusibility with the inner surface of the laminated film, and for example, polyethylene or polypropylene can be used. In particular, it is preferable that both the innermost layer of the laminated film and the take-out device 3 are formed of linear low-density polyethylene because of excellent sealing properties and strength.

The mounting portion 5 includes an oval flange portion 12 which is in contact with the upper end of the container body 1 from above, a cylindrical joint portion 13 fixed to the edge 1a of the container body 1, and an upper portion. A cap 9 for closing the opening is detachably screwed into the mouth 7.

The outer peripheral surface of the joining portion 13 is an edge 1a of the sheet body.
Are tapered on both sides so as to be in close contact with each other without any gap. The upper part 6a of the conduit part 6 faces the lower part of the mouth part 7 of the mounting part 5, is located below the upper surface of the mouth part 7, and the lower end of the conduit part 6 is near the bottom of the container body 1. positioned.

The conduit portion 6 has a cylindrical shape whose outer diameter is smaller than the inner diameter of the mounting portion 5, and is filled in the container body 1 between the outer peripheral surface of the conduit portion 6 and the inner peripheral surface of the mounting portion 5. The conduit portion 6 is provided concentrically with the mounting portion 5 so that a flow gap 15 through which the liquid to be flowed can be formed. Reference numeral 17 denotes a connecting portion connecting the conduit portion 6 and the mounting portion 5, and is provided at four locations in the circumferential direction of the mounting portion 5.

This embodiment is constituted as described above. Next, an example of use of the liquid container will be described. First, when filling the container body 1 with a liquid, the tip of the liquid filling nozzle 18 is inserted into the mouth 7 as shown by a virtual line in FIG. Therefore, even if the conduit portion 6 is provided with a small diameter, the opening 7 of the mounting portion 5 having a larger diameter than the conduit portion 6 has a guide positioning function of the liquid filling nozzle 18. The liquid can be stably filled, and the filling operation by automation can be performed efficiently and reliably. In addition, by filling the liquid into the conduit portion 6 with the liquid filling nozzle 18, the air in the container body 1 is discharged from the circulation gap 15, so that the space can be filled quickly without leaving any space inside.

Next, when the take-out device 3 is used as a straw for taking out a liquid, the cap body 9 is removed, and then the mouth part 7 is attached to the mouth part 7 to suck in the liquid. Therefore, the container is flattened so as to be closed from both sides, and the liquid in the container body 1 can be sucked up. In the initial stage of suction, the air in the container body 1 is also sucked through the gap 15 for circulation, but the air in the container body 1 is scarce or small, and the external air is introduced into the container body 1. Since the air does not enter, after the air in the container body 1 is evacuated, only the liquid is sucked through the conduit portion 6, and there is almost no hindrance to the suction of the liquid.

When the take-out device 3 is used as a spout, if the container body 1 is tilted or inverted so that the mouth 7 faces downward, the flow gap 15 acts as a take-out port. The liquid can flow out through the flow gap 15 and the mouth 7. When the liquid flows out, the liquid can be taken out under the same conditions as in the state where the edge 1a of the container body 1 is opened, so that the liquid can be effectively taken out to the last drop. Moreover,
When the container body 1 is pressed, the mounting portion 5 is rigid, and forms the communication gap 15 between the joint portion 13 of the mounting portion 5 and the conduit portion 6. The liquid can be forcibly and quickly taken out without closing the flow gap 15.

The present invention is not limited to the above embodiment. For example, as shown in FIG.
6a may be extended to the same height as the mouth 7 of the mounting portion 5. Also, the conduit part 6 shown in FIG.
The upper portion 6a projects upward from the mouth portion 7 and can be used as a mouth portion for sucking the upper portion of the conduit portion 6 when used as a straw.

Further, in the embodiment shown in FIG. 6A, the conduit portion 6 is formed in a semicircular shape, and the convex portion of the conduit portion 6 comes into contact with the inner peripheral surface of the mounting portion 5 which is separate. The flow gap 15 is formed between the flat portion 20 of the conduit portion 6 and the inner peripheral surface of the mounting portion 5. In the embodiment shown in FIG. 2B, flat portions 20 are provided on both sides of the conduit portion 6 along the conduit portion 6, and the flat portion 20 is provided between the flat portions 20 and the inner peripheral surface of the mounting portion 5. The gaps 15 are respectively formed.

[0020]

As described above, according to the present invention, the removal tool has a mounting portion which is hermetically secured to the edge of the container body, the conduit portion is inserted into the mounting portion, and the mounting portion is attached to the container portion. Since a distributing gap through which liquid can flow is formed between the container and the container, it is obvious that the dispensing tool can be used as a straw.If the dispensing tool is used as a spout, the container body is pressed strongly. Even so, there is almost no possibility that the container body that deforms inward closes the circulation gap, and the liquid can be quickly and reliably taken out to the last drop.
