Embodiment

[0090] Hereinafter, examples of the present invention are given to describe an example of effects, but the present invention is not limited by these examples.

[0091] The bags with openings of Examples 1 to 4 and Comparative Example 1 of the present invention were produced by the following method. As a sheet, a material obtained by making LLDPE (linear low-density polyethylene) obtained by polymerization with a metallocene catalyst into a film with a thickness of 250 μm is prepared, and two sheets of this sheet are heat-sealed to form a bag main body. The tensile modulus of the above-mentioned sheet was measured by the method of ISO527-1 and found to be 360 ​​MPa. The density of the above sheet was measured by the method described in ISO1872-1, and the result was 924kg / m 2 .

[0092] The opening part uses a bending elastic modulus of 1140MPa and a density of 964kg / m 2 HDPE (High Density Polyethylene) and made by injection molding. The total height of the opening part is ...

Abstract

A port-equipped bag (1) comprises a bag body (3) formed in a bag shape from a sheet, and a cylindrical port member (2) attached to the bag body (3). The port member (2) can be fitted with an inner plug (50) and a cap (4). The port member (2) has a fitting part (25) covered by the cap (4) when the cap (4) is fitted, and an annular lip (26) protruding towards the outer side of the port member (2). The lip (26) has an annular engagement surface (26A) facing a side of the bag body (3). In a cross-section along the axial direction of the fitting part (25), the engagement surface (26A) is disposed at 45-135 degrees with respect to the outer peripheral surface of the fitting part (25).

Description

technical field [0001] The present invention relates to a pouch with an opening provided in the pouch main body with an opening as an inlet and outlet for contents, and an inner plug that blocks the opening of the opening, and the inner plug is engaged with the opening and presses the inner plug. The bag with lid is especially suitable for aseptic filling of biopharmaceuticals and the like. [0002] This application claims priority based on Japanese Patent Application No. 2017-235604 filed in Japan on December 7, 2017, and the contents of the Japanese application are incorporated herein by reference. Background technique [0003] Infusion bags made of synthetic resin are widely used as containers for storing medical solutions such as injections. The infusion bag has a bag body (bag portion) for storing liquids such as medical solution and an opening for filling the bag body with the liquid or discharging the liquid from the bag body. It is formed by joining the opening mem...
