Abstract

<P>PROBLEM TO BE SOLVED: To provide a bag for storing a liquid which bag can be reduced in volume before storing the liquid to cut the transportation cost of the bag, and is adapted to leave as less liquid as possible when the liquid is sucked out of the bag. <P>SOLUTION: The bag is flexible, and contains a flexible suction auxiliary body, which prevents blocking of a liquid path upon sucking out the liquid. The suction auxiliary body is of a mesh shape or strip shape, and is made to fill the entire interior of the bag to cover from its mouth to bottom. It is desirable that the bottom of the mesh shape or strip shape on the bottom side of the bag be welded partly or entirely to the bottom of the bag. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a flexible bag made of plastic that contains a liquid such as a bag-in-box or an infusion solution.

  There is a problem that when a liquid is taken out by suction in a plastic flexible bag housing liquid for back-in-box or drip liquid, residual liquid remains.

Japanese Patent No. 3221701 (Patent Document 1) discloses a body fluid bag in which a side hole that opens to the outer periphery of a tube is formed at the tip of the tube.
Japanese Patent No. 2656935 (Patent Document 2) discloses a bag in box of a type in which a beverage filled in a bag in box is pressurized by supply of a pressurized fluid and poured out from a spout. Yes.

  In Japanese Patent Laid-Open No. 2002-02736 (Patent Document 3), at the final stage of suction, suction becomes impossible at the volume reduction limit due to the rigidity of the pouch, and a considerable amount of liquid remains in the container, which may be wasted. In order to provide a spout assembly that can take out highly viscous contents with little residual liquid, it is attached to the inside of the pouch body on one side of the flange surface located outside the edge of the pouch. The base and the other side are provided with a spout tube portion on the outside of the pouch when the pouch is attached, a spout body formed integrally with a synthetic resin, and a cap that is detachable from the spout of the spout body. In the outlet assembly, the adhesive base provided below the cone-shaped flange is located between the two sides of the pouch, and the two sides are easy to adhere to each other so that the liquid sealing property can be maintained. A spout main body is disclosed which is provided with a cylindrical blockage-preventing rib which is in the form of a cylinder and is provided below the adhesive base and communicates with the cylindrical part in the adhesive base and has a hole on the side surface. ing.

  In Japanese Patent Application Laid-Open No. 2004-159545 (Patent Document 4), a suction auxiliary tube having a liquid-permeable structure such as a mesh material or a perforated material is connected to a suction pipe of a thawing liquid take-out means, and the suction auxiliary tube is connected to the suction pipe. When the thawing liquid in the package is sucked and taken out by inserting into the package, it is prevented that the liquid part is difficult to be sucked by the presence of the suction auxiliary tube even if the package is reduced. It can be inserted into an outer container having the property of blocking microwaves, and is made of a material having microwave permeability and filled with a frozen fluid substance. A suction auxiliary tube having a liquid-permeable structure such as a material is inserted, and the internal freezing fluid substance is thawed by microwaves inserted into the outer container and irradiated from the opening, Bag, characterized in that they were taken out of the thawing liquid through the suction auxiliary tube is disclosed.

However, in the bag body disclosed in Japanese Patent Application Laid-Open Nos. 2002-02736 and 2004-159545, the suction auxiliary tube is a rigid plastic, so the bag body is bulky and the transportation cost is high. Also, because the interior tube does not cover the entire bag, a part of the bag is crushed due to atmospheric pressure, and the flow path cannot be secured, and there is still a considerable amount of residual liquid at the end of suction. there were.

  The present invention can reduce the volume of a bag body that contains a liquid before storing the liquid, reduce the transportation cost of the bag body, and reduce the residual liquid as much as possible when taking out the liquid by suction. An object of the present invention is to provide a flexible bag body that is provided with a plastic suction assisting body made of plastic.

The present invention provides a bag body in which a flexible suction assisting body is provided so that the bag or the strip-like body has a shape of a net-like body or a strip-like body extending from the mouth portion to the bottom portion of the bag body as a whole.
That is, the present invention relates to a bag having the following configuration.
(1) A flexible bag comprising a flexible suction auxiliary body.
(2) A flexible bag body in which the flexible suction auxiliary body is internally provided in a bag shape with a net-like or strip-like shape extending from the mouth portion to the bottom portion of the bag body.

  According to the present invention, the bag body that stores the liquid can be reduced in volume before the liquid is stored, the transport cost of the bag body can be reduced, and the liquid sucked when the liquid is taken out by suction. A path is secured and the remaining liquid can be reduced as much as possible.

  The flexible suction assisting body is internally provided throughout the bag with a net-like or strip-like shape from the mouth to the bottom of the bag. As for the bottom side of the net-like or strip-like bag body, it is desirable that a part or all of it be welded to the bottom part of the bag body.

  EXAMPLES The present invention will be described more specifically with reference to the following examples, but the present invention is not limited to the examples.

  FIG. 1A shows a bag body with a mesh-like flexible suction auxiliary body, and FIG. 1B shows a bag body with a strip-like net-like flexible suction auxiliary body. The flexible suction assisting body is internally provided throughout the bag with a net-like or strip-like shape from the mouth to the bottom of the bag. As for the bottom side of the net-like or strip-like bag body, a part or all of the bag body is welded to the bottom of the bag body. The strip shape is striped, but the cross-sectional shape can be a flat shape, a twisted planar shape, a wave shape, a curved shape, a tube shape, a shape with many holes on the outer surface of the tube, etc. Is possible. Suitable materials are polyethylene and polypropylene.

The bag body which equipped the flexible suction auxiliary body by this invention (A) mesh type, (B) strip type. The strip part (type AF) of the strip-shaped flexible suction auxiliary body in this invention (B). Conventional suction tube type bag. Conventional pressurized liquid discharge type bag body. A conventional suction assisting body-equipped bag (A) and tip portions (B) and (C) for assisting the suction. Conventional suction auxiliary body-equipped bag bodies (A) and (B).
