The present invention provides a container in which the tip end part of a barrel part is closed by a laminated film molded body, wherein the formation of wrinkles in the laminated film molded body is suppressed. A tip end part of a barrel part 2 of a container 1 is closed by a laminated film molded body 3 that includes a resin layer 11, 12 and a barrier layer 13. Provided to the laminated film molded body 3 is a shoulder portion 3b that protrudes to the tip end side while diminishing in diameter from a circumferential side part that is connected with the barrel part 2. A plurality of striations 31 that are in the form of recessed grooves or protruding ridges extending from the vicinity of the circumferential side part 3a to the tip end side are formed in the shoulder portion 3b in a radial manner.
The present invention uses a laminated film molded body including a resin layer and a barrier layer to improve the openability of a container having a body end closed. The tip of the body 2 of a container 1 is closed with a dome-shaped laminated film molded body 3 including resin layers 11, 12 and a barrier layer 13. The laminated film molded body 3 is provided with an easy-to-open treated section 20. The easy-to-open treated section 20 includes an opening trigger recess 21 that is formed of a compression mark compressed and plastically deformed in the thickness direction of the laminated film molded body 3.
The present invention ensures unsealing properties, and barrier properties or hermetic properties, for a container. A lid device 13 is provided so as to seal an opening 19e of a container body part 19 of a container 1. A lid-side member 20 of the lid device 13 is placed on the opening 19e, and a lid 30 is screwed onto a neck section 22 of the lid-side member 20. The lid-side member 20 and the lid 30 are heat-fused so as to be separable.

SOFT CONTAINER AND MANUFACTURING DEVICE AND METHOD THEREFOR
Provided is a soft container in which closing a tip of a body part by means of one member is enabled. The tip part of a flexible body part 10 of a soft container 1 is closed by a tip sheet member 20. The tip sheet member 20 has a peripheral side part 21, a shoulder part 22, and a top part 23 integrally and is configured from a self-supported film compact 28 of uniform thickness. The tubular peripheral side part 21 is joined to the body part 10. The diameter of the shoulder part 22 is reduced in a tapered shape from the peripheral side part 21 to the tip side. The tip part of the shoulder part 22 is closed by the top part 23.
B65D 35/00 - Pliable tubular containers adapted to be permanently deformed to expel contents, e.g. collapsible tubes for toothpaste or other plastic or semi-liquid materialHolders therefor
Provided is a bag that can be easily manufactured with a small number of parts and low man-hours and that can reliably prevent air intrusion. The bag 10 is provided with two films 11, 11. A bag body section 13 and an extended section 14 are integrally formed as a result of said films 11, 11 being placed to face each other. A sealed edge 16 is formed as a result of the two films 11, 11 being inseparably or integrally joined to each other at the edge of the bag body section 13. In the portion 13a inside of the sealed edge 16 of the bag body section 13 and in the extended section 14, the two films 11, 11 are temporarily fused to each other so as to be separable.
