Wide mouth container and method of making the same
A container and a method for making a container are provided. The method includes injection molding a preform having a body forming region, a neck forming region above the body forming region, and a dome forming region above the neck forming region. After forming the preform, the preform is mounted in a mold having a surface, the mold surface having a neck forming surface to form a neck having a snap fit portion or a threaded portion. After mounting the preform, the preform is stretched against the mold surface to form an intermediate article having a dome portion connected to a neck portion of the container. Thereafter, the dome portion is severed from the neck portion to produce a wide mouth container, wherein the ratio of a wall thickness of the neck forming region of the preform to the wall thickness of the neck portion is ranges from 4.8 to 7.
BLOW MOLDING MACHINE SUITABLE FOR MANUFACTURING A BOTTLE HAVING A HANDLE AND METHOD FOR USING THE SAME
A blow molding machine suitable for manufacturing the bottle having the handle and a method for using the same, wherein each of the preform holders has a local temperature regulating device, the local temperature regulating devices are disposed around the handle portion, the rotary joint supplies liquid or gas continuously to the local temperature regulating devices of the preform holders to perform continuous temperature regulation for the handle portion, thereby overcoming the problem that the temperature needs to be immediately cooled after the injection molding, and temperature of the body portion can be maintained, so as to achieve the purpose of reducing energy consumption.
Container and method
A blow molded container is provided. The container includes a neck having a neck finish and a transverse rim that defines an opening. A closure is provided that is engageable with the neck such that the rim is movable relative to the neck to define one or more vents configured for passage of a gas. In some embodiments, methods of use and manufacturing containers are disclosed.
Pulp Container with Fused Junction and Method of Making Same
Molded pulp containers with fused junctions and methods of making of same are provided. The present invention provides a pulp container, comprising a molded pulp body, wherein the body comprising a bottom and at least one side wall forming a cavity, wherein the at least one side wall comprising a upper rim, a neck, wherein the neck comprising a upper closure part and a lower rim, a fused junction, wherein a part of the upper rim of the at least one sidewall of the body and a part of the lower rim of the neck are aligned and fused together. The fused junction may be formed by ultrasonic welding.
GRAVITY RAIL SYSTEM AND METHOD FOR TRANSFERRING WIDE-MOUTH PREFORMS
A gravity rail system for transferring wide-mouth preforms comprising a first rail configured to support a first portion of the wide-mouth preform, and a second rail proximate the first rail, where the second rail further comprises a body that defines a cavity. The cavity is configured to receive a second portion of the wide-mouth preform. The cavity has an inner surface configured to prevent jamming of the wide-mouth preform as the preform is transferred along the gravity rail.
INJECTION-BLOW-MOULDING MOULD AND METHOD
The injection-blow-moulding mould comprises: a punch (1) having a blow opening (3) connected to a first conduit (5) which is in communication with a first source of pressurised gas supply (6) configured to supply pressurised gas through the blow opening (3) at an overpressure (OP) above a blowing pressure (BP) suitable to blow a preform (30a) into a container (30b) and an exhaust opening (4) connected to a second conduit (7) which is in communication with a pressure-limiting device set at the blowing pressure (BP); a blow-moulding cavity (2) configured to receive therein the punch (1) with a hot and soft preform (30a) arranged thereon; and a cooling device associated to the blow-moulding cavity (2). Gas inside the container (30b) exceeding the blowing pressure (BP) is allowed to escape through the exhaust opening (4) thereby a cooling gas stream is created from the blow opening (3) to the exhaust opening.
Stretch blow molding process
A stretch blow molding process for producing a plastic container from a preform, having an elongated, tubular preform body, extending along a center axis. The first end of the preform body is closed by a preform bottom and the second end is adjoined by a neck part with a pouring opening. A wall, bounds an interior space of the preform. The preform body is heated and introduced into a cavity of a blow mold. A stretching mandrel enters the preform until the stretching mandrel tip reaches the preform bottom. The preform body and the preform bottom are stretched by the stretching mandrel. The preform body and the preform bottom are deformed by introducing a fluid into the preform under pressure. The stretching mandrel makes contact with the inner side of the wall in the region of the preform body.
PET containers with enhanced thermal properties and process for making same
A process is provided for making a blow-molded PET container comprising a wall having a density of between about 1.370 g/cc and 1.385 g/cc, a heat-induced crystallinity of from about 18% to about 25%, and a strain-induced crystallinity of from about 55% to about 75%, wherein the PET container, when filled with a liquid having a temperature of from about 100 C. to about 132 C. or when subjected to a pasteurization or retort process, will not experience a change in volume of greater than 3%.
Preform temperature adjustment device and temperature adjustment method
In a blow-molding apparatus, a cooling device and a heating device are each driven by being supplied with electricity of a predetermined voltage from a supply power source. The blow-molding apparatus comprises: a monitoring device configured to constantly monitor fluctuation of the predetermined voltage; and an output automatic control mechanism configured to, in a case where the predetermined voltage monitored by the monitoring device fluctuates beyond a normal range, automatically fluctuate an output of at least one of the heating device and the cooling device to keep the output in a certain range, thereby adjusting at least one of the preform temperature and the ambient temperature to fall within a normal temperature range.
