Document Type and Number:
Japanese Patent JP2017154752
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a container with a discharge pump capable of suppressing buckling deformation of a container body when a discharge head is depressed, and capable of achieving thickness reduction of the container body.SOLUTION: A container body 10 comprising a mouth 11, a trunk 12 and a bottom part is formed into a double container which comprises an inner layer body 15, and an outer layer body 14 which introduces air into a space between the outer layer body and the inner layer body 15 from an outside air introduction hole 16 provided on a part corresponding to the mouth 11. A shoulder part 13 which deforms in a manner in which the mouth 11 is displaced downward with respect to the trunk 12 following depression of a discharge head 25, is provided between the mouth 11 and the trunk 12. An attachment cylinder 23a comprises a ventilation path formation part 23a2 for forming a ventilation path P for communicating the outside air introduction hole 16 to an outside, between the container body 10 and the attachment cylinder. The ventilation path formation part 23a2 is configured to close the ventilation path P by tightly contacting the container body 10 by deformation of the shoulder part 13 following depression of the discharge head 25.SELECTED DRAWING: Figure 1
