A hollow preform impact extruded from a metal billet to produce a progressing wall at a transition wall thickness. An axially forward portion of the progressing wall is ironed by extrusion past an extrusion point to form a sidewall portion of a lesser thickness. Extruding is stopped while some of the billet remains to form the closed bottom end. The preform has a bottom portion, a sidewall portion and a transition wall portion extending between the bottom portion and the sidewall portion. The transition wall portion is thicker than the sidewall portion and can be formed into at least part of the rim of an expansion shaped container. An impact extrusion punch has a central axis, an axially forward, impact surface for impacting metal to be extruded, a transition region for directing material displaced by the impact surface and a rear extrusion point for ironing material extruded past the transition region.

A container is provided that includes a top portion, a bottom portion and a plurality of sidewalls that each extend from an upper limit of the bottom portion, the top portion extending from upper limits of each of the side walls such that the sidewalls are positioned between the top portion and the bottom portion. The container comprises a plurality of indents therein, the indents being arranged in a configuration to avoid top load failure. That is, the indents provide strength to the container, which makes the container stronger than containers that are made from the same material, have the same weight and the same average wall thickness, but do not include indents.

A protective bottle enclosure for removably enclosing a bottle having a bottleneck ending in an open mouth. The enclosure includes a base section, a body, and a removable cap. The base section includes a cylindrical base sidewall secured to a perimeter of a base bottom wall and an open top. The body can removably engage the base section to cover the open top thereof. The removable cap includes a cap sidewall and a stopper that can removably engage the open mouth of the bottle. The stopper includes a stopper body and an annular ring extending radially outward from the stopper body. In use, the protective bottle enclosure can surround the bottle and seal the open mouth of the bottle when the base section is engaged with the body and the removable cap is engaged with the neck section.

A glass container that includes a base defining a hole, and methods of manufacturing and using the glass container, is disclosed. The glass container is manufactured by providing the container and cutting a hole in a wall of the container. The hole may be cut into the wall by any technique in which glass material is separated from the wall including by mechanical shearing, thermal energy, and/or fluid impingement. To use the glass container, a deformable blow-out plug may be inserted into the hole to fluidly seal the hole, a liquid beverage may be introduced into the container, a closure may be coupled to the container to close the container and provide a pressurizable package, and thereafter the package may be internally pressurized by introducing a pressurizing gas into the package.

A mold for producing a stretch-blow molded polyester bottle from a preform comprises mold parts that can be shifted between an open position and a closed position. The mold comprises: first and second mold shell, within which, in the closed position, a bottle body can be molded; a holding stopper, which can be inserted into a bottle neck; a blow pin having a compressed-air intake for biaxial stretching of the preform; and a bottom part, which closes the two mold shells at the bottom side and is configured to mold the bottle bottom. A base is formed on the bottom part, which base projects into an interior of the mold and has a side wall with an inclination angle (?) of at most 5 degrees with respect to a vertical axis (35) of the mold and is oriented in parallel with the vertical axis.

A bottle made of PET which can be filled with a hot, warm or cold liquid has a neck, a body and a closed bottom. The body has a peripheral groove for pressure relief capable of collapsing in a controlled manner under the bias of an externally applied vertical axial load. The structure of the groove is such that after collapsing the bottle will not be able to resume its original shape unless it is subjected to the application of another external force of sufficient strength in reverse direction with respect to the force which was applied to obtain the collapsed shape.

The present invention is a bottle that is formed from a synthetic resin material in a cylindrical shape having a bottom at one end, including: a plurality of circumferential grooves that extend continuously around the entire circumference of a body portion and are formed at a distance from each other in a vertical direction. The circumferential grooves extend cyclically in a circumferential direction while undulating in the vertical direction when viewed from the side of the body portion as to form wave patterns, and the respective phases of circumferential grooves that are mutually adjacent to each other in the vertical direction are offset from each other.

A combined wine glass and wine bottle package includes a wine glass constructed from molded plastic with an upper shell-shaped body defining an upwardly narrowing tapered flume of generally uniform thickness and a contoured lower base defining an annular moat surrounding a central punt. A wine bottle is sized to fit substantially into the wine glass in an inverted orientation with a removable bottle cap nested within the central punt, and with an upper rim of the wine bottle snap-fitted into a shallow groove formed in the wine bottle near a lower end thereof. This entire package is sterile-wrapped in a sealed shrink-wrap plastic or the like. The package can be opened when desired to permit removal of the wine bottle from the wine glass, following by bottle opening and pouring of the contents into the wine glass.

In a method, an article of unitary construction is blow molded and integrally provided with a clip for securement to another item. The clip has an arm initially blow molded into an open elevated configuration. The arm is pivotable into closed and open configurations. When closed, the arm is in selectively releasable and secure engagement with a catch on the article. The arm is biased towards the catch. When open, the arm is depressed relative to and biased towards the closed configuration. The open configuration is traversed to secure the article to the item. In the open elevated configuration, the arm is elevated relative to the closed configuration. The arm is preferably a carabiner-type arm. The article is preferably formed of a composition of matter including polyethylene and plastic additives to provide the arm with sufficient pre-built tension to stay in the aforesaid selectively releasable and secure engagement.
