Abstract:
An apparatus (100, 200, 300) for fabricating a container (101, 202, 302) comprises an injection head (102) establishing fluid communication between an injection liquid source (104) and a preform cavity (107A, 201A, 301A) of a substantially tubular preform (101A, 202A, 302A) through a nozzle (103) of said injection head (102), a longitudinal axis (109) of said injection head (102) being substantially vertically oriented and passing through said nozzle (103), characterized in that said apparatus (100, 200, 300) further comprises a plurality of infrared-emitting elements (113, 204, 304) projecting infrared radiation (115, 207, 306) into an expansion zone (110, 208, 307) which is disposed adjacent to said nozzle (103) and about said longitudinal axis (109), and configured to accommodate said preform (101A, 202A, 302A) when it is positioned in fluid communication with said nozzle (103)
Abstract:
An apparatus (100) for fabricating containers comprising a plurality of mold segments (104A, 104B, 104C) defining a mold cavity (106) substantially in the form of a container and accommodating a substantially tubular preform (107) having a preform cavity (108) in communication with an open end (109); an injection head (110) establishing fluid communication with said preform (107); an injection cylinder (113) in fluid communication with said injection head (110) and configured to inject a volume of liquid (119) into said preform (107); and a closure cylinder (125) configured to exert a force on at least one of said mold segments (104A, 104B, 104C) to maintain them in a closed disposition; and characterized in that it further comprises a motor cylinder (124) driving said injection cylinder (113) and being itself concurrently driven with said closure cylinder (125) by a single pressure source (122).
Abstract:
An injection head (100, 200) for a container-fabricating apparatus, comprising a first nozzle (104, 204) establishing fluid communication between an injection liquid source (103, 203) and a preform cavity of a substantially tubular preform (108, 208), said first nozzle (104, 204) being configured to mate with a mouth (106, 206) of said preform (108, 208) , an annular mouth seal (107, 207) provided in said first nozzle (104, 204) creating a seal with said mouth (106, 206) of said preform (108, 208) when disposed in contact therewith.
Abstract:
A container-fabricating apparatus (100) comprises an injection head (101) establishing fluid communication between an injection fluid port (106) disposed therein and a preform disposed in communication with a nozzle (108) of said injection head (101), and a stretching rod (111, 211) mobile between a position projecting from said injection head (101) through said nozzle (108) and a substantially retracted position; said apparatus (100) The apparatus (100) further comprises a cleaning chamber (113) at least partially defined by a hollow, elongate housing (114) contiguous with and extending from said injection head (101, 201), a plurality of cleaning chamber ports (115A, 115B) in a wall of said housing (114) establishing fluid communication with said cleaning chamber (113), said stretching rod (111) being substantially disposed within said cleaning chamber (113) when disposed in said substantially retracted position.
Abstract:
An injection head (100, 200, 300, 400) for a container fabricating machine, comprises a first nozzle (104, 204, 304, 404) configured to establish fluid communication between an injection liquid source (103, 203, 303, 403) and a preform cavity (108, 208, 308, 408) in communication with a mouth (109, 209, 309, 409) disposed at an open end (110, 210, 310, 410) of said preform (107, 207, 307, 407)), the first nozzle (104, 204, 304, 404) of the injection head (100, 200, 300, 400) comprising a substantially tubular spout (106, 206, 306, 406) configured to be inserted into the open end (110, 210, 310, 410) of said preform (107, 207, 307, 407) and thereby create a seal with the preform (100, 200, 300, 400).
