摘要:
A plastic preform for forming blow molded containers including at least one internal wall member for use in playing a game with the container. The internal wall member extends completely across the hollow space, wherein the internal wall member has edge portions which engage the body portion and are joined thereto. The internal wall member preferably has markings thereon or material void areas therein indicating the results of the game played with the container. The invention also discloses the blow molded plastic container for playing the game, having the internally extending inner wall with legible markings or material void areas.
摘要:
A tubular preform for a blow-molded container. The preform has a closed end and an opposite open end, the relative dimensions of the ends being such that the closed end would be receivable in the open end of a similar preform to nest there were it not for the provision of an antinesting feature in the form of a plurlity of axially extending ribs which protrude inwardly from the inner surface of the preform adjacent to the open end to prevent entry of another preform.

This relates to a returnable/refillable container in the form of a blow molded polyester biaxially oriented bottle wherein the container includes a domed base construction wherein the wall thickness gradually and smoothly increases to a maximum at the center of the dome. This also relates to a specially configurated preform which is blow molded to form the container and a specially configurated blow mold cavity for receiving a preform having a lower axial projection in the form of an elongated gate without crushing.

A stretched bottle (1) has an inclined mouth portion (31). The bottle (1) is formed in a manner that a straight parison is set in a blow mold (M.sub.1, M.sub.2) having an inclined cavity (20, 404) to be stretched by a stretching rod (17) during an air-blow operation or that a curved parison (405, 512) is set in the blow mold (M.sub.1, M.sub.2) to be stretched by air-blow. The parison is curved or deformed by a defining mold (431, 711) or a pushing bar (514).

Apparatus and method for forming a self-standing skirt on the pressure bottom of a blow-molded carbonated beverage container. The preform is formed with an annular depending skirt, and the skirt is stretched with a stretch mechanism which engages all but a lower portion of the preform, so that during the stretching of the preform concurrently with the blowing of the preform in a bottle mold, the lower portion folds inwardly to form a bottom ledge on the stretched skirt. The mold is provided with a centering mechanism for assuring the centering of the preform within the mold cavity to assure that the preform skirt receives the skirt stretching mechanism.
摘要:
A preform (10) for producing a plastic preform for forming blow molded plastic containers which comprises: a neck portion (16) defining an opening; a tubular sidewall portion (24) depending therefrom; and an integral base structure (28) depending from the tubular sidewall portion to a closed end (32); the preform having an outside wall face and an inside wall face with one of these, in the base structure, having integrally formed thereon a plurality of filets (36), extending longitudinally of the preform and defining a reinforcement (38) of varying thickness spaced from the closed end and circumscribing the base structure, wherein the filets decrease progressively in width and radial thickness at least from the reinforcing ring toward the closed end. The preform is capable of forming a blow molded plastic container with a bottom portion (130) having a reinforcement of circumferentially continuous radially extending alterations in wall thickness with a regularly undulating cross-section along the circumference. Preferably the filets are integral with the inside wall face. The invention also covers a mold-core rod combination for making such a preform, a process of using such a preform to make plastic containers by stretch/blow molding and containers including containers when produced from said preforms or combinations, or by said process.
摘要:
A blown bottle useful for containing a carbonated beverage bottle is formed with an annular single thickness depending skirt formed integrally with the bottle bottom providing a self-standing support for the bottle.A parison or preform for the blow molding of bottle is formed with a rounded, closed bottom portion and a cylindrical and integral annular single thickness skirt portion, for use in blow molding of a carbonated beverage bottle having an integral skirt for free-standing.The method of making a self-standing bottle, such as for carbonated beverages and the like, includes the forming of a bottle preform with an annular depending skirt which surrounds a closed bottom portion, and blowing the preform while gripping the skirt portion and spreading it outwardly and downwardly in relation to the orientation of the bottle to form an annular support skirt or platform in the blown bottle.
摘要:
A synthetic resin thin-walled bottle, a tubular intermediate therefor and a method of producing a thin-walled bottle. The thin-walled bottle has ribs at least at its bottom portion, and the bottle bottom is raised up frusto-conically or has an undulatory shape. The tubular intermediate is first formed with ribs which become thin-walled protuberant ribs after blow molding. The thin-walled bottle is produced by blow-molding the ribbed tubular intermediate.
摘要:
A container (30d) of polyethylene terephthalate or similar thermoplastic material has a container body (32d), a mouth portion (37d) and a central bottom part (34d). The central bottom part consists of chiefly amorphous and/or thermocrystallized material and forms a bulge directed towards the interior of the container. A ring-shaped or band-shaped standing surface (36d) is arranged adjacent the transition of the bottom part into the container wall (32d). Adjacent to the standing surface the container has a circumferential area of material (35d) which through stretching and/or reshaping has undergone flow and through heating has acquired built-in stresses which tend to contract it. The surrounding circumferential area of material prevents the inward bulge of the central bottom part from straightening out and/or turning inside out when the pressure in the container is increased and/or when the temperature of the container material is raised.The invention also relates to a method and a device for achieving the container.
摘要:
A champagne bottom plastic bottle having the bottom reinforced by internal radiating ribs which are formed by solid material. The bottle is formed in the customary manner by utilizing a preform which has molded on the inner surface thereof longitudinal ribs. The preform is formed by conventional injection molding equipment which has been modified only to form along the lower part of the customary core member longitudinally extending rib forming grooves.
