Document Type and Number:
Japanese Patent JP7189098
Kind Code:
B2
Abstract:
To provide an intermediate molding of a synthetic resin container, and a manufacturing method of the synthetic resin container which improve work efficiency in filling with a content while improving transportation efficiency of a container before filling with the content.SOLUTION: An intermediate molding 101 of a synthetic resin container 100 includes a cylindrical spout part 10, and a body part 20 connected to a lower side of the spout part 10. The body part 20 includes: a separation part 22 which has an outer layer body 22a and an inner layer body 22b arranged on an inner side of the outer layer body 22a through a gas filled layer 22c, and is arranged so as to be connected to the spout part 10, and can separate the inner layer body 22b from the outer layer body 22a; and a non-separation part 24 which is arranged in a position connected to the separation part 22 and has an opening 28 in a position in which it is not separated in a thickness direction and is separated from the separation part 22. The separation part 22 closes a communication port 18 for communicating the spout part 10 and the body part 20 by extending on an inner side in a diameter direction beyond a position in which the spout part 10 and the body part 20 are connected.SELECTED DRAWING: Figure 4B
