JP2004182311A - Suspended bag for supply of liquid material - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a simple suspended bag for the supply of a liquid material, which can prevent the mixing of dust etc. into itself by easily resealing an opening formed by cutting. <P>SOLUTION: This suspended bag 10 for the supply of the liquid material, which is made of a synthetic resin film and provided with a pour-out port, and wherein the opening can be formed by the cutting, is equipped with at least two locking-implement inserting holes 30, which overlap each other at the folding and sealing of the opening after the formation of the opening, and/or a slit. Since the use of the bag enables the cut opening to be very easily resealed simply by being folded back, the mixing of the dust etc. into the bag during the supply of contents can also be prevented. Additionally, since having a simple structure and dispensing with an increase in the number of components and the number of manufacturing processes, the suspended bag can be manufactured in almost the same manufacturing process as a manufacturing process for a normal suspended bag and made excellent in production efficiency. <P>COPYRIGHT: (C)2004,JPO&NCIPI

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a hanging bag for supplying a liquid substance, and more particularly, to a hanging bag for enclosing and supplying a liquid substance such as a liquid food, an enteral nutrient, an infusion solution, and drinking water to a human body.
[0002]
[Prior art]
Conventionally, as such a hanging bag for supplying a liquid substance, various types of bags have already been reported or put to practical use. For example, in an enteral nutritional supplement or a liquid food hanging bag, the contents such as liquid foods are often added at the time of use, or drinking water is replenished for dilution. A hanging bag made of a synthetic resin film provided with a pre-opening portion for forming a film is also reported (for example, see Patent Document 1).
[0003]
However, when such an opening is provided, although the opening can be cut and opened to easily add contents and replenish drinking water, there is a resealing means in the opening. Therefore, there is a problem that dust and the like easily enter after the cutting opening.

[Problems to be solved by the invention]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional problems, and is a simple suspension for supplying a liquid material, which can easily reseal an opening formed by cutting and prevent dust or the like from being mixed. The purpose is to provide a bag.
[0006]
The present inventor has conducted various studies in order to achieve such an object. As a result, two or more locking tool insertion holes and cuts are provided at positions overlapping each other when the opening of the bag body is folded and sealed. If it is provided, it is possible to reseal the opening simply by inserting and suspending a hook or other locking tool at the overlapping hole or cut, without specially providing a special resealing means such as a zipper. It has been found that mixing of the like can be prevented, and the present invention has been completed.
[0007]
[Means for Solving the Problems]
That is, the present invention is a hanging back for a liquid material supply made of a synthetic resin film having a spout and capable of forming an opening by cutting, which overlaps with each other when the opening is folded and sealed after the opening is formed. The above object has been achieved by a hanging bag for supplying a liquid substance, which is provided with two or more holes for inserting fasteners and / or cuts.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0009]
FIG. 1 is an explanatory front view of a hanging bag for supplying a liquid substance of the present invention. In FIG. 1, reference numeral 10 denotes a bag body made of a synthetic resin film. The method of forming the bag body 10 is not particularly limited. For example, a heat sealing bag-making method is a preferred method. In addition, regardless of the resin material (eg, barrier film, nylon, polypropylene, etc.), size, form (eg, flat body, square bottom body, etc.), color, transparency, opacity, etc., depending on the amount and use of the contents It can be selected appropriately.
[0010]
Reference numeral 20 denotes a spout, which is provided at one corner of the bag body 10. It is preferable to attach a tube connecting connector (not shown) to the spout 20, and it is preferable that the spout 20 and the connector are integrally formed.
The spout 20 may also be made of any material (eg, metal such as iron, aluminum, titanium, and copper; plastic such as polypropylene, polyethylene, polyethylene phthalate, and ABS resin), size, form, color, and transparency / opacity. Irrespective of the content, it can be appropriately selected depending on the amount and use of the contents.
[0011]
Reference numeral 30 denotes a locking tool insertion hole, two of which are formed so as to overlap with each other when the opening P (see FIG. 2) cut and formed in the bag body 10 is folded and sealed. The specific shape of the locking tool insertion hole 30 is not particularly limited as long as it overlaps with the opening P at the time of folding and sealing. However, the welding side edge 11 of the bag body 10 formed by heat sealing is not limited. It is desirable to form it in a high strength. In this case, it is preferable that the welding side edge 11 forming the locking tool insertion hole 30 is slightly wider (wider area) than other welding portions.
[0012]
The number of the locking tool insertion holes 30 may be two or more to seal the opening P, and is specifically selected according to the number of times the opening P is folded. However, the greater the number of shapes, in other words, the greater the number of times of folding, the higher the sealing performance of the opening P.
[0013]
The size and shape of the locking tool insertion hole 30 are not particularly limited, and can be appropriately selected according to the locking tool such as a hook, a rod, a string, and the like. For example, as shown in FIGS. As shown, they may be of different sizes and different shapes. In addition, instead of the locking tool insertion hole 30, for example, a cut 31 as shown in FIGS. 4 (3) to (5) may be used.
[0014]
Reference numeral 40 denotes a cut for forming an opening, and a pair of cuts is formed at the opposite side edge of the bag body 10. Incidentally, the cuts 40 serve as marks of the opening-formed portion by cutting, and make the cutting operation easier.
[0015]
FIG. 2 is a schematic explanatory view showing an example of use of the hanging bag of the present invention provided with three locking tool insertion holes 30 (30a to 30c). Hereinafter, the method of using the hanging bag of the present invention will be described with reference to FIG.
[0016]
After the contents are added or drinking water is replenished from the opening P formed by cutting, the opening P is inserted into the upper locking tool insertion hole 30a of the bag body 10 and the middle locking tool insertion hole. It is folded and sealed with the hole 30b, and the holes 30a and 30b are overlapped (see FIGS. 2 (1) and 2 (2)). Next, the intermediate locking tool insertion hole 30b and the lower locking tool insertion hole 30c are further folded, and the three holes 30b, 30a, and 30c are overlapped (FIGS. 2 (2) to (2)). 3)). Next, in a state where the bag body 10 is suspended by inserting a hook (not shown) such as a hook into the holes 30b, 30a, and 30c and suspending the bag body 10, the opening P is held in a resealed state. Therefore, mixing of dust and the like is prevented.
[0017]
FIG. 3 is a schematic explanatory view showing an example of use of the hanging bag of the present invention provided with two (30a, 30b) locking tool insertion holes 30, except that the number of times of folding of the opening P is one. Used in the same manner as 2.
[0018]
【The invention's effect】
If the hanging bag for supplying a liquid substance of the present invention is used, the cutting opening can be resealed very simply by simply folding the cutting opening, and therefore, it is possible to prevent dust and the like from being mixed during the supply of the contents. . Moreover, since the hanging bag of the present invention has a simple structure and does not require an increase in the number of parts or the number of manufacturing steps, it can be manufactured in almost the same process as a normal hanging bag, and is excellent in production efficiency. .
