Problems solved by technology

However, this liquid storage bag has such a disadvantage that, on the one hand, if the width of the partition wall is reduced, the partition wall may be peeled off due to careless drop, etc., and on the other hand, if the width of the partition wall is increased, the partition wall is difficult to peel off. needs to be improved

experiment example

[0014] Using a plastic laminated sheet with a wall thickness of 99 micrometers, the weak seal portion unsealing by dropping was performed on the liquid storage bag (Example) having the characteristics of the present invention in the weak seal portion and the liquid storage bag before improvement (Comparative Example) Experiment (drop experiment), and obtained the results shown in Table 1. In addition, the size of the liquid storage bag is 280 mm in length and 200 mm in width. The heat-sealing width of the sealing portion was 10 mm, the sealing strength was 40 N / 15 mm, and the heat-sealing strength of the weak sealing portion was 12 N / 15 mm. Furthermore, in the embodiment, the width of the weak seal is 3 mm at the center and 8 mm at both ends. In the comparative example, the widths of both the central portion and both end portions were 3 mm. In addition, the drop test was performed for each outer box unit (18 bags). In the examples, this test was performed on two boxes of bag...

Abstract

A liquid storage bag having a partition wall allowed to be peeled easily and not peeled by an accidental drop, etc. The upper part of the liquid storage bag is closed with a freely openable and closable zipper 2, and the bottom of the bag is provided with a liquid outlet 4, an easily peelable partition wall (a weak seal part 3) being provided close to the zipper. The internal space of the liquid storage bag is divided liquid-tightly into upper and lower parts through this weak seal part 3, liquid is stored in the lower part of the internal space (liquid storage chamber 1), and the weak seal part is formed in chevron form at a centre 31 and increased in width at both end parts 32 thereof.

Description

technical field [0001] The present invention relates to a liquid storage bag for pre-storing liquid, and more particularly, the present invention relates to an improvement of the liquid storage bag which is the subject of the invention of Japanese Patent Application Laid-Open No. Hei 11-28551. Background technique [0002] In the past, it has been popular to inject enteral nutrition into patients who are difficult to take nutrition orally by inserting catheters through the nose and mouth. Specifically, enteral nutrition contained in an enteral nutrition bag or an enteral nutrition bottle is injected into a patient's body through an infusion set and a catheter. Enteral nutrition is prepared by adding water or warm soup to the concentrated liquid or powdered enteral nutrition. After being prepared in other containers, the enteral nutrition is transferred to the enteral nutrition bag or enteral nutrition bottle, or directly in an enteral nutrition bag or enteral nutrition bott...
