Drug package bags and sheet for the bags

Abstract

Disclosed is a long sheet (10) for drug package bags which is prevented from being torn along any of incisions (b, 16) by tension during running, etc. and which gives drug package bags (A) having the effect of being easily opened through tearing. The sheet (10) is folded down the width-direction center, and a drug (a) is introduced into the space between the two halves (11, 11) of the folded sheet. Full-width areas of the sheet (10) which are respectively located ahead of and behind the drug (a) and the whole open edge parts of the two halves are fusion-bonded (12, 13) to obtain the drug package bags. The open-edge-side fusion-bonded part (13) is formed inside, and a plurality of fine incisions (width, 4 mm) for tearing (16) are formed along the whole machine direction of the sheet (10) in the area ranging from the fusion-bonded part (13) to the open edge part, the incisions (16) being formed inside the edge (17) of the open edge part at a distance of 1 mm therefrom so that an area (18) having no incisions is left between the incised part and the edge (17) of the open edge part. Due to the presence of the area (1-mm wide) (18) having no incisions, the sheet does not suffer the tearing caused by tension along an incision, and the sheet can be smoothly drawn out. Meanwhile, the bags can be easily torn because of the incised part.

Description

technical field [0001] The present invention relates to a bag for packaging medicines such as scattered medicines and tablets, and a sheet for the medicine packaging bag. Background technique [0002] Now, not only for each drug, but also for morning, noon, and night, the drugs that are taken in the morning, noon, and evening are divided into one bag and delivered to patients. Refer to that which shows one embodiment of the invention of the present application figure 1 , figure 2 To illustrate, these packaging methods are generally as follows: the strip-shaped sheet 10 is folded at the center of its width direction, and the medicine a is injected between the folded two sheets 11, 11, and the folded strip-shaped sheet is The entire front and rear width of the medicine a of the sheet 10 (overlapping sheets 11, 11) and the entire length of the opening edge of the folded two sheets 11, 11 are thermally bonded (the front and rear entire width bonding portion: 12, and the openi...

AI Technical Summary

Problems solved by technology

[0014] The drug packaging bag A with the above-mentioned scar b is effective in tearability, but problems arise when the drug a is injected and packaged using the above-mentioned elongated sheet 10

[0015] That is, in the above-mentioned drug packaging, since the elongated sheet 10 is pulled out from the roll, when it is pressed by the heating roller during thermal bonding, and when it is pulled out after thermal bonding, When (feeding out), not only the longitudinal direction but also the widthwise direction also acts on the deformed tension. Therefore, due to this tension, the sheet material 10 cannot be pulled out, and the smooth sheet 10 cannot be pulled out (running) due to the tension. bad situation
