A container includes a top portion and a bottom portion. The top portion includes a shoulder that extends away from a neck of the container, and a grip portion. The grip portion defines an integral logo portion and is recessed within the top portion of the container. A waist or groove is provided on adjacent lateral sides of the grip portion and may include a lateral stiffening rib. The bottom portion of the container includes a plurality of vacuum panels that accommodate for internal forces tending to cause collapse of the vacuum panels during a hot-fill process. Any portion of the internal forces not accommodated by the vacuum panels in the bottom portion of the container is accommodated by an auxiliary vacuum panel, which is provided in the grip portion of the container.

A preform for use in blow molding a bottle that is non-refillable and suitable for holding a non-carbonated liquid is provided. The preform may have a transition region, or nullstep,null on its inner surface. The step may strengthen the region between body and base portions of a bottle that results from blow molding the preform. The body portion of the bottle may be substantially cylindrical. The base portion of the bottle may have a slight inward concavity and may have a substantially constant wall thickness.

The shock-absorbing wall structure can be used to equip transport containers which may suffer major falls, generating very high energy on impact. It is chiefly made up of several layers of a cellular bearing structure (7, 7N, 7Nnull1 . . . ) in which some metal blocks are regularly placed. These blocks are positioned in staggered manner from one layer to another, so as to leave regular spaces in which they can expand in the event of impact. Particular application to transport containers such as fuel rods from nuclear plants or so-called type C containers (Transport Regulations for Hazardous MaterialsnullEdition 96nullIAEA Document, Vienna).

A blow-molded plastic container is provided suitable for hot-filling under pressurize-fill conditions, and under gravity-fill conditions. The container includes opposing handgrips within panels, which lack hinges and thus do not function as conventional vacuum panels as the inward deformation is spread beyond the panels. The hand grip includes a distal, relatively stiffened portion formed by a sidewall that forms a thumb piece and a proximal, relatively un-stiffened portion the smooth merges into a cylindrical sidewall of the container.

A container having opposing ends joined by a closing member, which closing member carries (a) a plurality of spread-apart ribs that radially encompass the periphery of the closing member, and (2) a plurality of radial sub-portions between adjacent ribs which sub-portions encompass the periphery of the closing member and a plurality of facets carried by the sub-portions.

A heat-resistant hollow cylindrical container comprising a neck, a shoulder, an upper body, a middle body provided with pressure reduction absorbing panels, and a lower body including a bottom wall, wherein said pressure reduction absorbing panels are arranged symmetrically relative to a central axis of the container, each of said pressure reduction absorbing panels is located inside an imaginary outer periphery of the cylindrical shape of the container, and each of said pressure reduction absorbing panels is provided with at least a pair of protuberances to be hooked by a finger. The middle body is provided with two pressure reduction absorbing panels arranged symmetrically respective to the central axis of the container. Said protuberances form a gap therebetween, and have a width and a height so sized as to allow a finger tip to be placed into the gap. Said middle body is also provided with groove-shaped ribs arranged along the upper and lower edges of thereof to absorb changes in an internal pressure in the container. Each of said groove-shaped ribs has an eccentric profile with a depth gradually decreasing to become nil in one of the lateral sides of the body.

A bottle-type plastic container has a body and an opening at one end of the container that allows liquid content to be filled into the container and emptied therefrom. The body includes at least one body portion having a substantially regular polygonal cross-section defined by a plurality of generally flat walls. The generally flat walls of the body portion include flexible walls and less-flexible walls, which are arranged alternately to each other in a circumferential direction of the body portion. When the container is filled with liquid contents at a high temperature and subsequently cooled to room temperature, a resultant pressure drop within the container is absorbed by the walls, initially by a primary inward deflection of the flexible walls and subsequently by a secondary inward deflection of the less-flexible walls. As such, the plastic container is particularly suited for hot fill applications.

This invention is titled nullBottle for hot filling use, equipped with vacuum absorption panels in the bottle portion.null The purpose of this invention is to provide a PET bottle having structurally improved vacuum absorption panels in the bottle portion so as to increase the panels' resistance to the constricting force of the shrink label, to secure the force of restitution for the panels, and thereby to allow the liquid level in the bottle to lower when the cap is opened. The means to achieve this purpose is given by the vacuum absorption panels in a configuration comprising multiple, flat and variable surfaces (15) and (20), which somewhat stand back from the plane of each corresponding main body wall; and multiple, horizontal and grooved ribs (16) and (21) having respectively a curved bottom (18) with the middle portion of this bottom being slightly uplifted, and with each rib being placed under a variable surface in an alternately disposed manner.

The title of the invention is the structure of reinforcing ribs around bottle waist. The purpose of the invention is to achieve enhanced buckling strength in a bottle of a reinforcing rib structure comprising a horizontal concave rib in the waist portion of the bottle body and the reinforcing ribs disposed vertically at regular intervals along the circumference of this horizontal concave rib. The means to achieve this purpose is to give the bottle a configuration comprising: A bottle composed of neck (1), shoulder (2), body (3), and bottom (4), said body (3) consisting of an upper body (7), a lower body (8), and the waist (9) between the upper and lower bodies; A horizontal concave rib (16) forming itself into said waist (9) and consisting of a concave wall connected to the lower end of said upper body (7), a concave wall connected to said lower body (8), and the bottom (16c) of the concave between these upper and lower concave walls; and Reinforcing ribs (18), which are disposed in the vertical direction at regular intervals along the circumference of said horizontal concave rib (16); Wherein said vertical reinforcing ribs (18) are designed to be narrow in the central part and wide at either or both ends, where each of said ribs is integrated with the peripheries of concave walls of said horizontal concave rib (16).

The tank for storing gas at high pressure, such as a tank for a vehicle running on gas, comprises a confinement volume accessible via coupling means and defined by a duct disposed in a spiral coil so that the substantially rectilinear main portions of the duct bear against one another. The forces exerted by the pressure of the gas on the main portions of a turn of the duct are then compensated by the forces exerted on the adjacent turns of the duct.
