摘要:
To provide a resin container and a method for manufacturing the same with which it is possible to generate more effervescence than hitherto. This resin container is provided with: a resin container main body inside which is formed an accommodating space that is hermetically sealed using a cap; and a textured region which is formed on an inner surface of the container main body and is formed from a rough surface.
摘要:
A method for forming and filling a container with liquid. The container being formed from a preform located within a mold and the method utilizing a hydraulic blow molding device that is coupled to a source of the liquid, which is used as the blow molding medium. The hydraulic blow molding device has a blow nozzle and a member that is extended from a retracted position to a position within the preform. A blow nozzle engages in fluid tight communication with an open end of the preform so as to provide a sealing engagement of the blow nozzle with the preform. The liquid blow medium is injected into the preform so as to form the container after sealing engagement of the blow nozzle with the preform. The member initiates its advancement into the preform prior to the time of sealing engagement of the blow nozzle with the preform.
摘要:
Use of optimized piston member for generating peak liquid pressure. A one-step hydraulic blow molding system and method for forming a preform and a liquid filled container from the preform. The machine and method include a sealing mechanism that forms a seal primarily utilizing compressive forces in an axial direction to prevent the leakage of liquid blow medium. The sealing mechanism includes an axial end face of a forming head and an upper axial surface of a neck ring.
摘要:
A mold device and a method related thereto for forming a plastic container from a preform. The mold device comprises a mold defining a mold cavity, a stretch initiation rod system for engaging an interior portion of the preform to define a stretch initiation area, and a centrally disposed pressure source positionable within the preform for introducing a pressurized fluid.
摘要:
An improved stretch rod tip having a hollowed area for receipt of a portion of a preform and at least a portion of a sprue during stretch blow molding of a container. Upon hardening of the container, the received portion of the preform becomes a protective dome over the received portion of the sprue that is at least partially internal to the container and that greatly reduces cracking, shearing, or other fracturing of the container due to a drop impact.
摘要:
A mold device for forming a plastic container from a preform. The mold device comprises a mold defining a mold cavity and a central exterior rod system moveably disposed within the mold cavity. The central exterior rod system is positionable between an extended position engagable with the preform and a retracted position spaced apart from the preform. The central exterior rod system maintains a central orientation of the preform during formation.
摘要:
An apparatus for forming a container from a container preform. The apparatus includes a housing, a mold cavity, and a nozzle system disposed in the housing and operably connectable to the mold cavity. The nozzle system is positionable between a first position engaging the housing along an interface of contact preventing pressurized liquid from being injected into the container preform and a second position spaced apart from the housing permitting pressurized liquid to be injected into the container preform. The nozzle system further includes in some embodiments a seal portion having a first surface—the first surface engaging a second surface extending from the housing in the first position.

A multilayer plastic container comprises a layer of a polypropylene and an intermediate layer directly adjacent the layer of polypropylene wherein at least one of the polypropylene and intermediate layers comprises an adhesive such as maleic anhydride incorporated therein to adhere the layer of polypropylene to the layer of EVOH.
摘要:
The process and apparatus of stretch-blow molding a preform in the axial and radial directions into a biaxially oriented container by the use of a stretching rod assembly and a blowing of pressurized fluid. In the axially stretching step, the surface area of the working end of the stretching rod assembly is changed. The axially stretching step is carried out through a plurality of stages each of which provide a different surface area of the working end of the stretching rod assembly. The apparatus preferred to carry out this process has a plurality of concentrically disposed stretching rods and an tip piece fixedly mounted on the working end of each of the stretching rods and having an external diameter at the surface area different from those of the other stretching rods. When such stretching rods are driven independently or in combination, the bottom surface area of the stretching rod assembly to be engaged by the inner bottom wall of the preform can be easily changed.
摘要:
The present invention provides an injection stretch blow molding apparatus in which a peripheral edge of a flat preform forms the edge or lip portion of a cup-like container. A securing or grip mold and a core mold are brought together to form the lip. The securing or grip mold is carried on the underside of a rotary transfer disk. The peripheral edge of the preform is sandwiched in between a shoulder formed at the lower end of a blow core and the securing or grip mold when stretch blow molding is performed, resulting in a cup-like container. The finished container is then removed upwardly from the securing or grip mold.
