A method and apparatus for storing and dispensing fluids such as syphon seltzer water under about 10 atmospheres of pressure. A plastic bottle is provided in which a valve mechanism is inserted within the neck of the bottle. A disposable cap covers the end of the bottle to prevent contamination of the valve during storage. When the contents of the bottle are to be dispensed, the cap is removed and discarded and a head member is attached to the outside wall of the neck of the bottle. The head con...

A syphon package (12) incorporates a deformable, resilient plastic sealing member (42) which, in its normal position, blocks passageway (50) for dispensing seltzer water (32) stored under pressure in the package (12). Tube (30), valve sealing member (42) and insert (44) are assembled by bonding insert (44) to flange (40) with sealing member (42) in place. The resulting assembly is then bonded to interior wall (22) of necked opening (16). A syphon head (24) has a one-piece actuator (60) bonded to...

A syphon head (10) is configured to fit over neck (17) of a bottle (19) in sealing relationship. A lever (22) is mounted to exterior surface (13) of body (12) by breakaway filaments (26, 28) and a spring strip (30). In use, the user pulls upward on handle (80) of lever (22) to rupture the filaments (26, 28). The strip (30) pivots end (48) on lever (22) through opening (78) in body (12) and into cavity (46) in actuating rod (38). Actuating rod (38) is attached to interior surface (20) of the body...

A package (10) includes a polyethylene terephthalate (PET) container (12) having a necked opening (14). A PET insert (18) is fixedly attached to an inside surface (30) of the necked opening (14) by a plurality of tack welds (34). The insert (18) makes a substantially line contact (32) with the inside surface (30) of the necked opening (14). The substantially line contact (32) extends continuously around the inside surface (30) of the necked opening (14) to form a fluid tight seal between the ins...

A package (10) includes a polyethylene terephthalate (PET) container (12) having a necked opening (14). A PET insert (18) is fixedly attached to an inside surface (30) of the necked opening (14) by a plurality of tack welds (34). The tack welds (34) are formed within recesses (44) that extend completely through the wall of the necked opening (14) and into the insert (18). The insert (18) makes a substantially line contact (32) with the inside surface (30) of the necked opening (14). The substant...

A filling apparatus (20) for a syphon package has a pivotally movable cradle (26A, 26B, 26C) configured to receive a syphon bottle 1 in a first orientation. A permanent syphon filling head (38A, 38B, 38C) is near necked opening (2) of the bottle when the bottle is loaded in the cradle (26A). Arms (28A, 28B, 28C, 30A, 30B, 30C) move the cradle (26A, 26B, 26C) from the first orientation to the second orientation in which the necked opening (2) of the bottle (1) is directed downward. Linkages (42A,...

A valve assembly (52) has a valve housing (64) which fits in neck (76) of container (50). Valve member (88) is slidably movable in housing (64). Housing (64) has a plurality of grooves (86) and apertures (80), which interact with flanges (92, 94, 96) to define flow paths in the valve assembly (52). The flanges (92, 94, 96), inside surface (84), apertures (80), slots (86) and valve member (88) provide a flow path through the valve assembly (52) when the valve member (88) is in its downward positi...

A package (10) for dispensing a fluid (26) in the package under gas pressure has a biaxially oriented polyethelene terepthalate bottle (12) with a neck (14). A dispensing head (22) is attached to the neck (14). A normally closed valve (16) is mounted in the neck and has a housing (50) sealed to the inside surface of the neck (14). The housing (50) has a syphon flange (54). An integral structure (56) having a spring (58) at one end and a poppet (60) at a second end rests on the syphon flange (54)...

A syphon seltzer package (10) consists of a polyethylene terephthalate (PET) plastic bottle (12) with a neck (16) having an opening (18), into which a valve insert (20) is mounted. The insert (20) is held in place by mechanical attachment. The insert (20) fits into a sleeve (50) in an interference fit. Projections (52) on the outside of wall (32) insure a positive seal between the insert (20) and the sleeve (50). Similar projections (54) on the outside surface (56) of the sleeve (50) provide a p...

A valve (20) has a valve housing (22) with a central passage (28) extending axially through the valve housing (22). Aperture (40) in the valve housing connect a second passage (38) to the central passage (28) to extend through the valve housing. A poppet valve member (24) is configured for sealing engagement of the central passage (28). The valve member (24) is urged into sealing engagement with the central passage (28) by internal pressure in a container (36) on which the valve (20) is provided...
