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.

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.

A hot-fill PET container or bottle (10) filling with a liquid at an elevated temperature has a side wall (9) extending to a lower portion including a pressure panel (11) and a base (21) in its unfolded or pre-fill position. The panel (11) is transversely oriented and has a decoupling or hinge structure (13), an initiator portion (1) and control portion (5) of a steeply angled inverting conical section between 30 and 45 degrees. The control portion enables the inversion of the panel (11) into the container (10) to compensate for vacuum or reduced pressure induced within the container as the liquid cools down. The base (2) can also have a plurality of reinforcing ribs (3).

A threadless plastic blow molding device includes a main molding-base, a bottom molding-base, and a blow molding-base. The main molding-base has two mating portions each defines a recessed cavity. The recessed cavities correspond to each other when the mating portions are mated. The bottom molding-base and the blow molding-base are respectively assembled to two ends of the main molding-base. The blow molding-base has a gas blowing portion. The main molding-base, the bottom molding-base, and the blow molding-base collectively define a forming space for forming a blank. The blow molding-base has an expanded portion extended toward the mating portions. Each of the mating portions has a recessed section corresponding to the expanded portion. Accordingly, the blank can be positioned in the molding device.

Method for forming a packaging (2) from a container (1) that has a body (5), a neck (8), and a bottom (6), the container (1) having a deformable zone (15) with an extended configuration in which the zone (15) projects toward the outside of the container (1), with a retracted configuration in which the zone (15) projects toward the inside of the container (1), with this method including the following operations: filling the container (1) with a hot product; closing in an airtight manner the thus filled container (1); measuring the temperature of the stoppered container (1); comparing the measured temperature to a preset threshold value; if the measured temperature is less than or equal to the threshold value, moving the deformable zone (15) back toward its retracted position.

A multifunctional detabber apparatus and method for producing bottles having a bottom surface with a hook projection integrally molded with and extending from the bottom surface in a deployed position. The bottom surface also includes at least one locking channel in order to receive and releasably secure the hook projection in a non-deployed position. The multifunctional detabber apparatus includes at least a grabber, a trimmer, and a hook closer. The grabber includes first and second jaws which surround the bottle and prevent movement. The trimmer includes first and second strikers for creating an outer periphery of the hook projection and an opening in the hook projection. The hook closer includes a mandrel that extends to bend and secure the hook projection in the locking channel in the bottom surface of the bottle.

The intermediate stretched-blow molded container (1) comprises a biaxially stretched-blow molded hollow body (10) that comprises a container side wall (10a), at least one recess (101) that is formed in said container side wall (10a), that is off-center from the second vertical central plane (P2), and at least one convex and outwardly protruding deformable region (102) that is formed in the container side wall (10a). The maximum gripping dimension (DR) of the stretched-blow molded hollow body (10) measured next to and on one side of the convex and outwardly protruding deformable region (102) is smaller than the maximum dimension (DL) of the stretched-blow molded hollow body (10) measured next to and on the other side of convex and outwardly protruding deformable region (102). Said convex and outwardly protruding deformable region (102) comprises an outwardly protruding invertable lateral wall (1020) that is an extension of a second lateral wall (1011) of the recess (101) and that extends beyond a first lateral wall (1010) of the recess (101), and a front wall (1021) that is an extension of this outwardly protruding invertable lateral wall (1020). The junction (H) between the bottom portion (1012) and the second lateral wall (1011) of said recess (101) forms an hinge on the whole periphery of the outwardly protruding convex deformable region (102) for inverting the said outwardly protruding convex deformable region ((102) and the second lateral wall (1011) of the recess (101) by pushing them inwardly in order to form a concave grip (G).
