A discharge container has: a container body and an inner layer body; a discharge cap; and a valve, wherein the discharge cap includes a top wall portion having the discharge port, and a cylindrical side wall portion connected to the top wall portion, and an annular second seal portion and a second engagement portion are provided at an inner peripheral surface of the side wall portion, the second seal portion abutting against a first seal portion of the mouth portion located below the outside air introduction hole on a whole circumference, and the second engagement portion undercut-engaging with a first engagement portion located at an outer peripheral surface of the mouth portion above the first seal portion.

Discharge container

A double-walled container includes a plurality of ribs. The plurality of ribs include at least one expanded diameter part rib whose upper end is disposed immediately below at least one diameter expansion part of ring and at least one intermittent part rib whose upper end is disposed immediately below at least one intermittent part of ring located immediately below at least one air introduction hole. The at least one intermittent part includes an extending portion extending beyond the upper end of the at least one expanded diameter part rib.

Doubled-walled container

A double-walled container including: an outer layer body; an inner layer body, which is provided in a pinched-off portion and which passes through the outer layer body. The pinched-off portion is formed in a bottom due to pinch-off using a splittable mold in blow molding. The bottom is provided, on an inner side in a radial direction of an outer edge portion thereof, which serves as a ground-contacting surface, with a substantially cross-shaped recess, which is concave toward a mouth. The recess is configured by a first-direction recess portion, which extends along an extending direction of the slit, and a second-direction recess portion, which intersects with the first-direction recess portion. The slit is provided in a region in which the first-direction recess portion and the second-direction recess portion intersect with each other.

Double container

A dispensing container provides that after discharging content, the content which has not been returned to an internal container is prevented from leaking out of a discharge port. The dispensing container has an internal container which contains content and an external container in which the internal container is attached. The external container is provided with a suction port for sucking external air in between the internal container and the external container. A discharge cap is attached to a spout and is provided with a discharge port for discharging the content. The discharge cap includes an inside plug which closes the spout and a cylindrical body covering the inside plug and being provided with the discharge port. The inside plug is provided with a communication port. A valve that is slidable along an axial direction of the communication port is provided to open and close the communication port.

Pour spout

A squeezable plastic bottle with a handle which is bendable by forming a bending deformation portion in the handle. The bending deformation portion of the handle can be a bending portion formed in the middle portion of the longitudinal direction of the handle. Further a bending rib can be formed between the handle and the body wall surface. The body may be squeezable and deformable by forming a bending rib in the bottle body.
