According to the present invention, there is provided a liquid storage bag having a partition wall allowed to be peeled easily and not peeled by an accidental drop, etc.
The liquid storage bag involving in the present invention is one wherein the upper part thereof is closed with a freely openable and closable zipper 2, the bottom thereof is provided with a liquid outlet 4 and an easily peelable partition wall (a weak seal part 3) is 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 outside-convex form at a center 31 and increased in width at both end parts 32 thereof.
1. A liquid storage bag wherein the upper part thereof is closed with a freely openable and closable closing means, the bottom thereof is provided with a liquid outlet, the internal space of the bag body is divided liquid-tightly into upper and lower parts by an easily peelable partition wall provided close to the closing means, liquid is stored in the divided lower internal space, and the partition wall is formed in outside-convex form at a center part and increased in width at both end parts thereof.
2. The liquid storage bag as claimed in claim 1, wherein the part upper than the closing means is sealed to enclose it.
3. The liquid storage bag as claimed in claim 2, wherein a notch is formed at the sealed side part enclosing the closing means.
4. The liquid storage bag as claimed in any one of claims 1 to 3, wherein the width of both end parts of the partition wall is two times or more as broad as that of a center part.
5. The liquid storage bag as claimed in any one of claims 1 to 4, wherein the closing means is a zipper.
6. The liquid storage bag as claimed in claim 5, wherein the upper parts adjacent to both end parts of the zipper are heat sealed.
7. The liquid storage bag as claimed in any one of claims 1 to 6, wherein the liquid is a concentrated enteral nutrient.
[0007]FIG. 1 is a schematic plain view indicating an example of the present invention. In FIG. 1, 1 indicates a liquid storage chamber, 2 does a zipper (a closing means), 3 does a weak seal part (an easily peelable partition wall), 31 does a central part, 32 does both end parts, 4 does a liquid exit, 5 does a hanging hole, 6 does a feeding open, 7 does the heat seal part, 8 does the seal part and 9 does a notch.
[0008]FIG. 2 is a plain view of a liquid storage bag disclosed in Japanese Patent Application Laid-Open No. Hei 11-285518. In FIG. 2, 1 indicates the bag body, 11 does a hanging hole, 2 does a liquid exit, 21 does a closing member, 3 does a zipper, 4 does a partition wall, 41 does a weak seal part and 5 does a feeding open.
The upper part of the liquid storage chamber constitutes the feeding open 6 for feeding water or warm water which dilutes the preliminarily stored liquid, e.g., a concentrated enteral nutrient and the feeding open 6 is closed with a zipper 2 serving as a freely openable and closable closing means. This zipper 2 has a structure to be closed by fitting a convex stripe into a concave stripe and can be opened and( closed when so required, said convex and concave stripes being respectively formed to the inner wall of the bag located in opposed positions. Incidentally, in case that the feeding open 6 is molded in cylindrical shape, the cover body to be fitted into said feeding open 6 may also be used as the closing means. Here, in order to prevent the contamination of the inner wall located at the upper part of the bag, the part upper than the zipper 2 may be sealed to enclose it. The side part of the seal part 8 enclosing the zipper 2 may be formed with a notch 9 for making the seal part removable. Also, it is preferable that the upper parts adjacent to the both end parts of the zipper 2 are provided with the heat seal 7 by a method such as heat seal so that leakage of the liquid never occurs after the liquid preparation has been prepared in the bag and the zipper 2 has been closed.
A drop method was applied wherein the case was placed for 24 hours for humidity-control under an atmosphere of 20° C. and 65% RH and thereafter dropped 6 times from the height of 60 cm (when dropped, the place to collide on the floor: 1 time at the corner, 3 times at the edge and 2 times at the side) and dropped 2 times from the height of 90 cm (when dropped, the place to collide on the floor: the bottom).
