Package

Abstract

Provided is a package that has a bag body, at least one mouth part member bonded to the bag body, and a contained product which is a liquid housed in the bag body, the package being characterized in that: the bag body of the package is formed in a bag shape by using, as a material, laminates each having a sealant layer and a water vapor barrier layer composed at least of a fluorine-based resin, and by bonding together the sealant layers opposing each other so that the sealant layers are to be located on the inside of the bag body; the mouth part member is sandwiched between the oppositely facing sealant layers and is bonded thereto; the volume V of the contained product housed in the bag body is 0.1-20 cm3; and the relation between the area S (cm2) where the bag body is in contact with thecontained product housed in the bag body and the aforementioned volume V (cm3) satisfies 0.05<=V / S<=0.25 (formula (I)).

Description

technical field [0001] The present invention relates to a package containing, for example, liquid contents such as medicines supplied to epidural, arteriovenous, subcutaneous, muscle, and various organs, and is small, lightweight, and portable, Moreover, the quality of the medicine is not easy to change, and the residual amount of the medicine after administration is extremely small. [0002] this application claims priority based on Japanese Patent Application No. 2017-236530 for which it applied to Japan on December 8, 2017, and uses the content here. Background technique [0003] In the continuous administration of hormones, anesthetics for pain relief, anticancer agents, or antibiotics, the usual method is to inject these liquids into subcutaneous, blood vessels, muscles, epidural, and various organs through micropumps. Wait. At this time, the administration can be controlled by an electric circuit or a computer, and a minute amount of administration or finely controll...

AI Technical Summary

Problems solved by technology

[0014] However, in this method, since the curved surface of the film is processed, there is a problem that the material of the film needs to have thermoformability.

In addition, if the alignment between the cartridge base and the storage membrane is not strictly performed, there is a problem of increased residual liquid volume

Due to these problems, this method is not ideal in terms of productivity and manufacturing cost

In addition, if the storage film is thinned to make it easy to deform, there is a problem that the water vapor barrier property is lowered and the concentration of the chemical solution is likely to change.
