摘要:
A method for the fabrication of a container from a substantially tubular preform provided with an open end communicating with a cavity comprises the steps of positioning the preform within a mold that substantially defines a container such that the open end of the preform protrudes from the mold; providing an injector in sealed fluid communication with the open end of the preform which injects a quantity of liquid into the cavity of the preform, increasing the pressure within the cavity and inducing the preform to deform into the shape of the mold and form a container; and then reducing the pressure within the container to atmospheric pressure while maintaining sealed fluid communication between the injector and the open end. Using the method for fabricating and filling a beverage container.
摘要:
The invention concerns a method of simultaneously blowing and filling a container from a thermoplastic polymer preform with a carbonated liquid at ambient temperature having, said carbonated liquid having a defined quantity of dissolved carbon dioxide (CO2) depending on the carbonated liquid beverage, comprising: —stretching the thermoplastic polymer preform (16) placed within a mold (12) during a stretching phase, —starting an injection phase for injecting said carbonated liquid into the preform, the injection phase starting after the stretching phase has started, characterized in that prior to starting the injection phase the carbonated liquid is at a predetermined pressure (P1) equal or greater than the partial pressure (P2) of the carbon dioxide (CO2) defined for said carbonated liquid beverage in the container. The invention also concerns related system.
摘要:
An apparatus for the fabrication of a container (300), comprising a mold defining the form of said container (300) and configured to accommodate a substantially tubular preform, an injection head (115) configured to interface with the preform and establish fluid communication with a cavity thereof; an injection valve (202) configured to selectively permit fluid communication through said injection head (115), and a stretching rod (117) slideably disposed within the injection head (115); said apparatus (100) further comprising a displacement plunger (209) being disposed coaxially about and mobile relative to said stretching rod (117) between a retracted position substantially within the injection head (115) and an extended position wherein said displacement plunger (209) projects at least partially from said injection head (115).
摘要:
An apparatus (500) for fabricating containers (511) comprises a plurality of mold segments (501A-501I) each with two substantially opposite faces (510A-510I) that form a mold cavity (509A-509I) when abutted against another mold segment (501A-501I), and a guiding means (502) to conduct them along a closed path (503) of length greater than the total length of the mold segments (501A-501I); being characterized in that it comprises at least one injecting head configured to inject a volume of liquid into a cavity of a preform (507) disposed within the mold cavity (509A-509I) and expand it into a container (511), and being further characterized in that each mold segment (501A-501I) is conducted along the closed path (503) through at least one manipulation zone (505, 506) of said closed path (503) at an increased speed relative to the immediately adjacent mold segments (501A-501I), said apparatus (500) comprising a positioning manipulation zone (505) where the preform (507) is inserted into said apparatus (500), and an extracting manipulation zone (506) where the container (511) is extracted.
摘要:
An apparatus (100) for the fabrication of a container (300) comprising a mold (121) defining the form of said container (300) and configured to accommodate a substantially tubular preform, an injection head (115) configured to interface with the preform (108) and establish fluid communication with a cavity thereof; and an injection valve (202), said injection valve (202) configured to selectively permit fluid communication through said injection head (115); said apparatus (100) further comprising at least one compression means (303A, 303B) mobile relative to said mold (121) such that said at least one compression means (303A, 303B) is disposed outside said mold cavity (105) in a retracted position and projects into said mold cavity (105) in an extended position.
