A synthetic resin container has improved formability while preventing deformation of corner walls. The synthetic resin container includes a mouth that serves as a dispensing opening for contents, a body that is continuous with the mouth via a shoulder, and a bottom that closes a lower end of the body. The body includes a pair of main walls arranged so as to face each other with a gap therebetween, a pair of side walls arranged so as to face each other with a gap therebetween, and corner walls that couple respective ends in a circumferential direction of the main walls and the side walls. Each corner wall is provided with U-shaped ribs that are formed in a substantially U-shape within a surface of the corner wall and that are concave toward an inner side in a thickness direction of the corner wall.

A synthetic resin container has an outer layer body and an inner layer body and formed by biaxial stretching blow molding. The synthetic resin container has a cylindrical mouth portion, a shoulder portion located below the mouth portion and having a diameter gradually increasing downward, a body portion being continuous with a lower end of the shoulder portion, and a bottom portion configured to close a lower end of the body portion. The mouth portion has an outside air introduction port configured to introduce outside air between the outer layer body and the inner layer body, and the shoulder portion has at least one shoulder rib forming a concave or convex shape and extending from the mouth portion side to the body portion side.

A collapsible travel bottle comprising a flexible main body comprising an inner space for receiving a liquid therein, the main body including an upper portion, a middle portion, and a lower portion, an opening in the upper portion in communication with the inner space to allow receiving and discharging of the liquid within the flexible main body, a rigid collar coupled to the upper portion proximate the opening, a rigid cap coupled to the rigid collar to restrict receiving and discharging of the liquid within the flexible main body through the opening, the middle portion configured to enable both the top portion and the middle portion to collapse fully into the bottom portion.

A blow molded bottle (1): a) which is self-collapsible during its emptying; b) which comprises at least two transversal grooves and/or ribs (6.1), preferably located in the tubular body portion (6), equipped with collapse starters (6.2); c) wherein the mean wall thickness (Tmean) of the tubular body portion (6) is—in an increasing order of preference—less than or equal to 200; 180; 160; 150 μm; preferably comprised between 65 and 150; and more preferably comprised between 90 and 130 μm. The invention also discloses a method, a preform (100) and a mold for the manufacture of the aforementioned container by blow molding. The invention also discloses a method for bottling liquid into the bottles (1), a method for dispensing the liquid, a dispenser for implementing the method and a method for packing the thin-walled bottles, in view of storage and transportation.

There is provided a resin container including an upper surface portion, a side surface portion connected to the upper surface portion, and a bottom surface portion disposed on a side opposite to the upper surface portion and connected to the side surface portion. A round corner surface portion is formed to the side surface portion. A first folding deformation inducing portion is formed on the round corner surface portion. When the container is viewed from a side surface portion side such that a central axis of the container and the round corner surface portion overlap with each other, the first folding deformation inducing portion is oblique with respect to the central axis.

A cylindrical bottle which collapses along helical groove, ridge and connecting rings along its sidewall. When inward force is applied along the bottle's vertical axis, the helical groove rings and connecting rings fold under the ridge rings and remain substantially “locked” under the ridge rings, thereby causing the sidewall to collapse and remain collapsed until sufficient outward force is applied. When sufficient outward force is applied along its vertical axis, the bottle extends as the distance between its helical groove rings and ridge rings lengthens. Due to the diamond-shaped cross-section of the connecting rings, in conjunction with the silicone composition of the bottle's body, the collapsing and extension of the bottle occur in sequential segments, creating a unique, playful sound and an amusing worm-like movement.

Provided is a plastic container with a bottom area and a main body, which adjoins the bottom area in a longitudinal direction of the plastic container, wherein the main body includes a wall which extends all the way around in a circumferential direction of the plastic container and an opening area which at least indirectly adjoins the main body in the longitudinal direction and has a container opening, wherein the circumferential wall of the main body includes at least one first groove and/or elevation extending in a first direction and at least one second groove and/or elevation extending in a second direction.

A container (100) includes a body (110) having an upper end (104) and a lower end (106). The upper end has an opening formed therethrough. The body defines a plurality of ribs (110) between the upper end and the lower end that are configured to actuate between an expanded state and a compressed state to vary a volume inside the body. A sleeve (500) is positioned at least partially around the body. The sleeve inhibits one or more of the plurality of ribs that are in the compressed state from actuating into the expanded state.

The invention relates to a container (1), preferably a bottle, which extends along a main axis (A) and comprising a wall forming a neck portion (2), a shoulder portion (3) connected to the neck portion (2), a body portion (4) connected to the shoulder portion (3), the body portion (4) comprising a grip portion (7), and a base portion (5) forming the bottom of the container (1) and connected to the body portion (4). The grip portion (7) comprises, over at least the majority of its dimension along the main axis (A), a plurality of spiral ribs (13) formed by the wall of the container (1) and spiralling in parallel around the main axis (A). The spiral ribs drastically increase side stability, compression and twisting deformation resistance of the container, while they have a non-technical and appealing appearance.

A synthetic resin-made container has an outer layer body and an inner layer body separably laminated on an inner surface of the outer layer body and is formed by stretch blow molding, and has: a tubular mouth portion; a shoulder portion located below the mouth portion and increasing in diameter downward; a barrel portion connected to and located below the shoulder portion; and a bottom portion closing a lower end of the barrel portion, wherein the mouth portion has an outside air introduction hole for introducing outside air into a space between the outer layer body and the inner layer body, and the inner layer body is made of a crystalline resin, and has, in at least a part of the mouth portion in the inner layer body, a crystallized region having a higher degree of crystallinity than other regions.
