摘要:
In order to provide a check valve capable of sufficiently suppressing the mixing of air into the container even if a certain impact is applied to the container and also capable of stably maintaining good pouring of the content, a check valve 10 of the invention is formed of rubber material and manufactured by integral molding. The check valve 10 has a tubular main body 1 having openings 1 a and 1 b at opposite ends, a lid 3 arranged to close one opening 1a of the main body 1, and a hinge 5 that connects the main body 1 and the lid 3. The lid 3 has a projection 3a on the side surface 3b, the projection 3a coming in contact with a peripheral edge of the opening 1 a of the main body 1.

To provide a container including an inner container that is deformed as content decreases, the container being a dispensing container reusable and excellent in an aroma retaining property. To implement such container, a dispensing container (10) includes a container body (13) including a flexible inner container configured to be filled with content and to deflate as the content decreases, and an outer container encompassing the inner container and having an intake hole through which external air is taken into a space between the inner container and the outer container, a discharge cap (15) including a top surface part having a discharge port through which the content is discharged, the discharge cap (15) being mounted on a mouth portion (13a) of the container body (13), and an external air introduction hole that provides communication between the outside and the intake hole. The inner container and the outer container are made of a polyethylene terephthalate resin.

Provided is a synthetic resin multilayer bottle capable of reliably preventing a content composed of a liquid seasoning that contains soy sauce from deteriorating due to oxygen in outside air. A synthetic resin multilayer bottle 1 includes an outer shell bottle 2, which can restore an original shape thereof in response to deformation attributable to pressing, an inner container body 3 which deforms when pressed, and an air channel 23 through which outside air is introduced between the outer shell bottle 2 and the inner container body 3. The synthetic resin multilayer bottle 1 has oxygen permeability such that, after the inner container body 3 is fully filled with distilled water from which dissolved oxygen has been removed, an inner opening part 17 is sealed, and the distilled water is allowed to stand for 60 days at a temperature of 20°C while keeping the air channel between the outer shell bottle and the inner container body open, the amount of dissolved oxygen in the distilled water is 3 ppm or less.

[Problems] To provide a plastic cap having a pouring cylinder capable of pouring the content liquid smoothly maintaining a constant liquid width even in case the degree of inclination of a container is varied to some extent at the time of pouring the content liquid, and of easily adjusting the liquid quantity. [Means for Solution] A bill 20 is formed at an upper end portion of the pouring cylinder 11 provided in a top panel 5 of a cap body 1, the bill 20 protruding outward in an inclined manner, a lower end of the pouring cylinder 11 is forming a seal surface 17 of nearly a cylindrical shape, a groove 30 is formed in the inner surface of the bill 20 in the pouring cylinder 11 and is extending from an upper end portion of the seal surface 17 up to an upper end of the bill 20, and a seal ring 29 is formed on the inner surface of the upper lid 2 so as to come into close contact with the seal surface 17 which is the inner surface of the pouring cylinder 11 when the upper lid 2 is closed.

An object of the present invention is to facilitate discharge of the content in a dispensing container having a delamination structure so as to minimize the amount of remaining content. In order to achieve this object, a gas is housed in the internal container 11 to thereby form a gas space S therein and the volume of the gas is 4% or more of the volume of the internal container 11. The gas preferably moves rapidly in the internal container 11 when the dispensing container is tilted to a discharge posture in order to discharge the content M from the discharge port 14. The gas may be encapsulated in a gas bag or the gas may be encapsulated in a gas chamber formed in the internal container 11.

After discharging content, the content which has not been returned to an internal container is prevented from leaking out of a discharge port. In order to achieve this object, the present invention provides a dispensing container 10 comprising: a container body 13 having an internal container 11 which contains content and an external container 12 in which the internal container 11 is attached, the external container 12 being provided with a suction port 19 for sucking external air in between the internal container 11 and the external container 12; and a discharge cap 15 which is attached to a spout 13a of the container body 13 and provided with a discharge port 14 for discharging the content, wherein: the discharge cap includes an inside plug member 21 which closes the spout 13a and a cylindrical body member 23 having a top-closed cylindrical shape, the cylindrical body member 23 covering the inside plug member 21 and being provided with the discharge port 14; the inside plug member 21 is provided with a communication port 43 which communicates the discharge port 14 and the inside of the internal container 11; and a valve body 44 is arranged and fitted in the communication port 43 so as to be slidable along an axial direction O of the communication port 43, the valve body 44 being elastically displaced along the axial direction O to open and close the communication port 43.

Provided is a synthetic resin-made multilayer bottle in which a dead space can be reduced without being affected by the specifications of an outer opening section. A synthetic resin-made multilayer bottle (1) includes: an outer shell bottle (2) having a shoulder section (5) continuing from an outer opening section (4), and a body section (6) continuing from the shoulder section (5); a synthetic resin-made inner container body (3) having a cylindrical inner opening section (17) provided inside the outer opening section (4) of the outer shell bottle (2), and an inner container main body (18) continuing from the inner opening section (17), shaped along an inner surface shape of the outer shell bottle (2), which deforms by an external pressure; and an air passage (23) formed between the outer opening section (4) and the inner opening section (17) and which introduces outside air between the outer shell bottle (2) and the inner container body (3). The inner circumferential surface of the inner opening section (17) is provided with a small-diameter section (24) having a diameter smaller than the inner diameter of the open end of the inner opening section (17).
