Exemplary hot-fillable plastic containers are disclosed. In some embodiments, the containers may include a threaded neck portion, a body portion, and a base portion including a standing surface and a movable element. In some embodiments, the moveable element may be arranged to be recessed either substantially above, or substantially below, the standing surface in an initial pre-filling position.

A double-walled container includes an outer layer body and an inner layer body. A single adhesive strip is disposed between the outer layer body and the inner layer body in a manner such that the adhesive strip extends along a center axis. The outer layer body is provided with a single ambient air introduction hole. The outer layer body includes an inner surface, which is configured by a separation surface and a pseudo-adhesive surface. The separation surface faces the ambient air introduction hole and is separated from an outer surface of the inner layer body, and the pseudo-adhesive surface faces the separation surface and is separably adhered to the outer surface of the inner layer body.

A resin made container includes a spout portion to/from which a cap can be attached/detached, a shoulder portion continuous with the spout portion, a body portion continuous with the shoulder portion and a bottom portion continuous with the body portion and disposed at a lowermost portion of the bottle. At a lateral wall lower end of the bottom portion, there is formed a step which is receded to the inner side along a circumferential direction.

A plastic container has a base portion adapted for vacuum absorption, the container including a base and a body extending up from the base along a central axis to a finish portion defining a mouth. The base includes an outside wall, a chime connecting the outside wall to an annular contact ring, an inside wall extending upward from the contact ring to a hinge, and a diaphragm connected to the hinge. The diaphragm can move between first and second positions in response to pressure change within the container. The diaphragm includes a central region and a flexible wall having a curved profile in cross section. The flexible wall curves downward from the hinge to the central region. In some embodiments, the flexible wall is asymmetric and includes a first portion having a curved profile and a second portion having a linear profile. A container wall structure is also disclosed.

A resin made container includes a spout portion to/from which a cap can be attached/detached, a shoulder portion continuous with the spout portion, a body portion continuous with the shoulder portion and a bottom portion continuous with the body portion and disposed at a lowermost portion of the bottle. The bottom portion includes a bottom face which comes into contact with a disposing surface and a sloped portion extending with a slope from the bottom face to the body portion. At least a portion of a vertical cross sectional shape of the sloped portion is a linear portion or a curved portion which protrudes to the inner side of the container. An angle formed between the linear portion of the sloped portion and the disposing surface or an angle formed between a straight line interconnecting an upper end and a lower end of the curved portion and the disposing surface ranges from 15 to 70 degrees.

A beauty care product comprising a sealable plastic container, a sealing means and a beauty care component is provided, wherein the container of which is resistant to random, uncontrolled deformation under a substantial pressure differential between the environment and inside the container, yet having an affordable cost of manufacture and/or being appealing to the consumer. A kit comprising said product thereof, a method of manufacturing said product, and a method of using said product for application onto skin and/or hair are also provided.

Provided is a synthetic resin container that effectively absorbs the reduced pressure generated inside the container as a result of hot filling and that also prevents deterioration in appearance of a label applied to an outer circumferential surface of a trunk portion of the container. A synthetic resin container according to the present disclosure includes a mouth portion, a trunk portion, and a bottom portion. The trunk portion is provided with a plurality of reduced pressure absorbing panels extending in the vertical direction while twisting in the circumferential direction and being arranged side by side in the circumferential direction. Each reduced pressure absorbing panel has a narrow-width portion located in a region between the panel upper end and the panel lower end. A width of each reduced pressure absorbing panel is reduced in the narrow-width portion than in the panel upper end and the panel lower end.

A container comprising a body portion is provided. The body portion includes a flat upper vacuum panel, a flat lower vacuum panel, and a recess between the flat upper vacuum panel and the flat lower vacuum panel. In response to a change in the internal container pressure, the body portion flexes at the recess towards an interior of the container and the flat upper vacuum panel and the flat lower vacuum panel form a progressively smaller angle at the recess in response to an increasing pressure change.

A container including at least one sidewall. The sidewall includes first and second vacuum panels, and a plurality of first and second ribs. The first and second vacuum panels are recessed beneath an outer surface of the sidewall. The second vacuum panel is spaced apart from, and vertically aligned with, the first vacuum panel. The plurality of first ribs protrude outward from the first vacuum panel. The plurality of second ribs protrude outward from the second vacuum panel.

Provided is a double-walled container (1), which includes an outer layer body (2) and an inner layer body (3). A single adhesive strip (4) is disposed between the outer layer body (2) and the inner layer body (3) in a manner such that the adhesive strip (4) extends along a center axis (C). The outer layer body (2) is provided with a single ambient air introduction hole (2d). The outer layer body (2) includes an inner surface, which is configured by a separation surface (2f) and a pseudo-adhesive surface (2g). The separation surface (2f) faces the ambient air introduction hole (2d) and is separated from an outer surface of the inner layer body (3), and the pseudo-adhesive surface (2g) faces the separation surface (2f) and is separably adhered to the outer surface of the inner layer body (3).
