A synthetic resin container and method for manufacturing the same, including a container main body molded into a predetermined container shape and a covering layer laminated on an outer peripheral surface side of the container main body. The method includes heating the composite preform to bring the covering material layer into a molten state or a semi-molten state while softening the preform main body to be stretchable, subsequently molding the composite preform into a predetermined container shape by using a blow molding die in which an edge portion formed by providing a step on a cavity inner peripheral surface extends along a predetermined direction, and providing, in the covering material layer to be molded integrally with the preform main body, a thin portion molded by being brought into pressure contact with the edge portion.

Ways to produce a container (315, 415, 515, 720, 815, 915) having a shaped tail (610, 910) are provided that include blow molding a precursor having a tail (105, 110, 205, 310, 410, 510, 715, 810, 910) and shaping the tail (105, 110, 205, 310, 410, 510, 715, 810, 910) to form the shaped tail (610, 910). Various types of blow molding can employ various types of precursors having tails (510). Injection blow molding can be used where a preform (105, 200, 305, 405, 505) having a tail (105, 110, 205, 310, 410, 510, 715, 810, 910) is optionally longitudinally stretched and is expanded with a gas or a liquid. Extrusion blow molding can be used where a parison (705) having a tail (105, 110, 205, 310, 410, 510, 715, 810, 910) is expanded. A tail (105, 110, 205, 310, 410, 510, 715, 810, 910) shaping means can be part of the blow molding process or can be employed after the container (315, 415, 515, 720, 815, 915) is produced from the precursor having the tail (105, 110, 205, 310, 410, 510, 715, 810, 910). The shaped tail (610, 910) can impart functionality to the container (315, 415, 515, 720, 815, 915), including where the tail (105, 110, 205, 310, 410, 510, 715, 810, 910) is shaped into a coupling point that can serve as an attachment point, hanging point, or hook, for example.

A method of forming a balloon for a medical device is provided including extruding a cylindrical tube of silicone material, partially curing the cylindrical tube, inflating the cylindrical tube, and fully curing the balloon. The cylindrical tube is partially cured by exposing the cylindrical tube to a first ultraviolet light source. The cylindrical tube is inflated within a mold to form the balloon. The balloon is fully cured by exposing the balloon to a second ultraviolet light source.

In one embodiment, a method of processing a plastic container having a longitudinal axis is disclosed. The method includes: blow-molding a plastic container having an upper portion including a finish, a sidewall, a lower portion including a base defining a standing surface, and a substantially transversely-oriented pressure panel having an inner annular wall and a central push-up portion located in the base, wherein a base mold portion is displaced longitudinally with respect to first and second side mold portions to form the pressure panel set above the standing surface; introducing heated liquid contents into the plastic container with the pressure panel located in an outwardly-inclined position entirely between the standing surface and the upper portion; capping the plastic container; and, moving the pressure panel to an inwardly-inclined position entirely between the standing surface and the upper portion.

An extrusion blow mold machine forming hollow containers. The machine has at least one pair of opposing half molds that combine to form a mold and define a mold cavity. Each of the half molds is positioned on a carrier plate and includes first, second, and third mold segments. The first and third mold segments can move with respect to each other and with respect to the second, fixed mold segment. A mechanical structure creates vertical movement of the first and third mold segments relative to the second mold segment as the mold opens horizontally, without the aid of any electrical, hydraulic, or pneumatic device. A closing unit engages the carrier plate to move the carrier plate and its respective half mold toward and away from the opposing half mold and its respective carrier plate, thereby closing and opening the mold.

This resin-made container is provided with: a neck portion having a content inlet-outlet portion; a lateral surface portion connected to the neck portion; and a bottom portion that is disposed on the side opposite to the neck portion and that is connected to the lateral surface portion. The resin-made container is produced by a stretch blow molding process. The bottom portion has formed therein a bulge section that protrudes downward in the vertical direction. The bulge section is disposed in an eccentric region, of the bottom portion, positioned outside a region demarcated by perpendicularly projecting an opening plane of the inlet-outlet portion of the neck portion.

A mold for blow molding a container from a preform, the container including a wall portion and a base including a high standing ring and a central outwardly-inclined invertible diaphragm, the mold including sidewalls forming a counter print of the wall portion of the container (1) and a mold base (36) having an upper surface (37) defining a counter print of the container base, wherein the upper surface (37) includes: an annular peripheral face (43) corresponding to an annular support flange of the container base; a frusto-conical outer face (44) corresponding to an inner portion (11) of the high standing ring, the outer face (44) protruding upwardly with a draft angle (A2) from an inner edge of the peripheral annular face (43) up to a sharp apex (45), and a frusto-conical downwardly inclined inner face (46) corresponding to the invertible diaphragm.

Described are a mold and molding process for manufacturing devices and containers that are scalable, modular, and lockable laterally and vertically with other like devices or containers. The mold is formed with a cup mold and top end mold sections specially designed to allow for molding and demolding a container with an undercut. The cup mold includes, on a vertical wall, one or more undercuts. Multiple undercuts may further form tongues with undercuts each of which forms a groove with undercuts on the molded article, and/or one or more grooves with undercuts each of which form a tongue with undercuts in the molded article. Molding and Demolding of the article with undercuts is further enabled by utilizing an improved method of molding said article with an undercut, and demolding said article from the mold once it is molded, by improvements to each stage of the molding process, including the preform stage, the conditioning station stage, the blow stage and the release stage.

Method of making a blow-molded plastic container comprises forming a hollow blow-molded article comprising a main body portion defining an interior space, a finish portion defining a mouth in fluid communication with the interior space, the finish portion having a substantially cylindrical circumferential wall of generally uniform thickness surrounding the mouth, the circumferential wall having an upper edge with a perimeter flange and a pair of tabs projecting radially inward from the circumferential wall, the pair of tabs defining a spout therebetween, and a moil portion extending from the perimeter flange in a direction opposite the main body portion. Method further includes inflating the plastic material within the mold cavity to form the hollow blow-molded article and removing the moil portion from the perimeter flange. Blow-molded plastic container having a finish portion with directional pour spout and blow-molded article comprising container and moil portion also disclosed.

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.
