The present disclosure describes a hot-fill container for use with a hot-filling process. The container includes vacuum absorption sections that resist partial collapse and uncontrolled deformation of the container's walls during the hot-filling process. The vacuum absorption sections are asymmetrically-formed and include respective edge portions and panel portions configured to deform and pivot about a linear part of the edge portions when a vacuum is created inside the container. The edge portions have a curvilinear part that is adapted to comfortably receive and engage a user's fingers during use of the container, making the container more user friendly. The vacuum absorption sections are arranged about the container's central longitudinal axis such that their respective panel portions substantially form the sides of a polygon when viewed in top plan view. The polygon appears to be inscribed within an otherwise circular container periphery.

A synthetic resin container that effectively absorbs reduced pressure generated inside the container due to hot filling to maintain the appearance and shape. A synthetic resin container includes a mouth as a dispensing spout for a content medium, a trunk, extending contiguous to the mouth via a shoulder, and a bottom, closing a lower end of the trunk. The trunk is provided with reduced pressure absorbing panels, which are formed as ribs extending in the vertical direction while twisting in the circumferential direction about a central axis of the trunk and which are arranged side by side in the circumferential direction of the trunk. Twist angle of a lower end with respect to an upper end of each reduced pressure absorbing panel about the central axis is 50 degrees or more.

A container having an inverted active cage generally includes an enclosed base portion, a body portion extending upwardly from the base portion, and a top portion with a finish extending upwardly from the body portion. The body portion further includes a central longitudinal axis, a periphery, a plurality of rigidified and non-active surfaces, and a network of pillars or channels. Unlike the prior art, each of the plurality of non-active surfaces is outwardly displaced with respect to the longitudinal axis, while each of the network of pillars or channels is inwardly displaced with respect to the longitudinal axis. The plurality of rigidified or non-active surfaces, together with the network of rigidified channels or pillars, are spaced about the periphery of the container in order to accommodate vacuum-induced volumetric shrinkage of the container resulting from a hot-filling, capping and cooling thereof.

A container includes a base, a neck portion, and a body positioned between the base and the neck portion. The base includes a plurality of feet with a plurality of recesses positioned between the plurality of feet. The body includes a plurality of ribs, a plurality of channels, and a plurality of support columns. The plurality of ribs extend around a periphery of the body and along at least a portion of a height of the body. The plurality of channels extend around the periphery and are positioned between the plurality of ribs. The plurality of support columns are spaced about the periphery and extend along at least a portion of the height of the body. Each of the plurality of support columns includes a plurality of protrusions that are vertically aligned. Each of the plurality of protrusions is disposed within a respective one of the plurality of channels.

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.

A peripheral groove is defined by a bottom surface, an upper side surface, and a lower side surface, and, in at least one of the upper side surface and the lower side surface, a radially outer end edge of an end portion positioned at a circumferential end portion of a panel surface portion is further away in a bottle axis direction from the bottom surface toward an adjacent corner surface portion when viewed from the outside in the radial direction.

A plastic container comprises an upper portion including a finish defining an opening into the container, a lower portion including a base defining a standing surface, a sidewall extending between the upper portion and the lower portion, the sidewall defining a longitudinal axis, and at least one substantially transversely-oriented pressure panel located in the lower portion. The pressure panel is movable between an outwardly-inclined position and an inwardly-inclined position to compensate for a change of pressure inside the container. The standing surface defines a standing plane, and the entire pressure panel is located between the standing plane and the upper portion of the container when the pressure panel is in the outwardly-inclined position.

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 container has an outer layer body and an inner layer body mainly made of a polyester resin and is formed by biaxial stretch blow molding, and includes: a mouth portion; a shoulder portion, gradually increasing in diameter in a downward direction, and having an outward protruding curved shape over a length in a vertical direction in a longitudinal section; a barrel portion; and a bottom portion, wherein the mouth portion has an outside air introduction port for introducing outside air between the outer layer body and the inner layer body, and the double container includes a shoulder rib that is concave or convex as seen from outside and at least extends from an upper end of the shoulder portion to the lower end of the shoulder portion.
