  • Patent number: 11312523
    Abstract: A synthetic resin-made multilayer bottle includes: an outer shell bottle having a shoulder section continuing from an outer opening section, and a body section continuing from the shoulder section; a synthetic resin-made inner container body having a cylindrical inner opening section provided inside the outer opening section of the outer shell bottle, and an inner container main body continuing from the inner opening section, shaped along an inner surface shape of the outer shell bottle, which deforms by an external pressure; and an air passage formed between the outer opening section and the inner opening section and which introduces outside air between the outer shell bottle and the inner container body. The inner circumferential surface of the inner opening section is provided with a small-diameter section having a diameter smaller than the inner diameter of the open end of the inner opening section.

  • Patent number: 11155398
    Abstract: 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.

  • Publication number: 20200239174
    Abstract: A synthetic resin multilayer bottle includes an outer shell bottle, which can restore an original shape thereof in response to deformation attributable to pressing, an inner container body which deforms when pressed, and an air channel through which outside air is introduced between the outer shell bottle and the inner container body. The synthetic resin multilayer bottle has oxygen permeability such that, after the inner container body is fully filled with distilled water from which dissolved oxygen has been removed, an inner opening part 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. Such bottle prevents a liquid seasoning containing soy sauce from deteriorating due to oxygen in outside air.
