Abstract

Abstract In a process for making a filled and closed container of heat-sealable plastic hose, in one work operation, the hose is expanded to become a container body, the body is filled and the upper part of the container is shaped when the container is closed. After the filling process and before closing, the upper part of the container is closed by a rubber stopper. An apparatus to carry out the process includes a container-molding appliance having a lower and upper mold parts, with a mold holding fixture in each of the upper parts which can be displaced in the direction of movement of the upper mold part and be moved automatically opposite the upper mold part, and with a holding device inside the plastic hose which can be moved vertically. The holding device releasably holds the rubber stopper for insertion into the completed container body. The holding device is attached to a cross slide which permits horizontal movement, so that the rubber stopper can be moved from a receiving location to the container being formed.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 139 words
An apparatus for forming, filling and closing a container by expanding and shaping a heat-sealable polymeric hose, the apparatus comprising a container-forming mold with split upper and lower parts, and a mold-holding fixture for each of the upper mold parts movable in opposite directions; means movable at least vertically inside the hose for releasably holding a rubber stopper; a cross slide for supporting said means for holding said stopper for horizontal movement relative to said mold; and means, carried on said cross slide and operatively associated with said means for holding said stopper, for establishing a predetermined position of the upper mold parts after said stopper is introduced into the hose; whereby said means for holding can be moved to a receiving position for engaging a stopper and to a position in the hose for placing the stopper therein.
Claim 2
Independent Claim 139 words
An apparatus for forming, filling and closing a container by expanding and shaping a heat-sealable polymeric hose, the apparatus comprising a container-forming mold with split upper and lower parts, and a mold-holding fixture for each of the upper mold parts movable in opposite directions; means movable at least vertically inside the hose for releasably holding a rubber stopper; a cross slide for supporting said means for holding said stopper for horizontal movement relative to said mold; and means, carried on said cross slide and operatively associated with said means for holding said stopper, for establishing a predetermined position of the upper mold parts after said stopper is introduced into the hose; whereby said means for holding can be moved to a receiving position for engaging a stopper and to a position in the hose for placing the stopper therein.
Claim 3
Dependent Claim 18 words
An apparatus according to claim 1 comprising a slide for carrying a rubber stopper into said receiving position.
Claim 4
Independent Claim 132 words
An apparatus for forming, filling and closing a container with a stopper by expanding and shaping a heat-sealable polymeric hose completely about the stopper, the apparatus comprising a container-forming mold with split upper and lower parts and a mold-holding fixture for each of the upper mold parts movable in opposite directions; filling means for supplying contents to the hose while in said mold; stopper handling means, movable at least vertically inside the hose from above said mold after filling the container, for releasably holding a rubber stopper; and a cross slide for supporting said stopper handling means for horizontal movement relative to said mold; whereby said stopper handling means can be moved to a receiving position for engaging a stopper and to a position in the hose for placing the stopper therein.
Claim 5
Independent Claim 132 words
An apparatus for forming, filling and closing a container with a stopper by expanding and shaping a heat-sealable polymeric hose completely about the stopper, the apparatus comprising a container-forming mold with split upper and lower parts and a mold-holding fixture for each of the upper mold parts movable in opposite directions; filling means for supplying contents to the hose while in said mold; stopper handling means, movable at least vertically inside the hose from above said mold after filling the container, for releasably holding a rubber stopper; and a cross slide for supporting said stopper handling means for horizontal movement relative to said mold; whereby said stopper handling means can be moved to a receiving position for engaging a stopper and to a position in the hose for placing the stopper therein.
Claim 6
Dependent Claim 49 words
An apparatus according to claim 3 wherein said cross slide carries stop means, operatively associated with said stopper handling means, for holding said upper mold parts in a predetermined position after the stopper is introduced into the hose and before the stopper is released from said stopper handling means.
Claim 7
Dependent Claim 17 words
An apparatus according to claim 4 wherein a slide carries the rubber stopper to said receiving position.
Claim 8
Dependent Claim 43 words
An apparatus according to claim 4 wherein each of said upper mold parts comprises first and second relatively movable sections, said first sections having means for molding a container head and said second sections having means for molding the hose to the stopper.
Claim 9
Dependent Claim 20 words
An apparatus according to claim 6 wherein said stop means engages said first sections to position said upper mold parts.
Claim 10
Dependent Claim 23 words
An apparatus according to claim 6 wherein spring means resiliently bias said first and second sections of each of said upper mold parts.
Claim 11
Dependent Claim 43 words
An apparatus according to claim 3 wherein each of said upper mold parts comprises first and second relatively movable sections, said first sections having means for molding a container head and said second sections having means for molding the hose to the stopper.
Claim 12
Dependent Claim 23 words
An apparatus according to claim 9 wherein spring means resiliently bias said first and second sections of each of said upper mold parts.
Claim 13
Dependent Claim 17 words
An apparatus according to claim 3 wherein a slide carries the rubber stopper to said receiving position.
Claim 14
Dependent Claim 30 words
An apparatus according to claim 3 wherein said mold comprises means for retaining the stopper in position in the hose and means for molding the hose completely about the stopper.
Claim 15
Independent Claim 119 words
An apparatus for forming, filling and closing a container by expanding and shaping a heat-sealable polymeric hose, the apparatus comprising a container-forming mold with split first and second parts and a mold-holding fixture for each of the first mold parts movable in opposite directions said first parts having means for molding the hose to the stopper and being relatively movable relative to said second parts; stopper handling means, movable at least vertically inside the hose, for releasably holding a rubber stopper; and stop means, operatively associated with said stopper handling means, for holding said first mold parts in a predetermined position after the stopper is introduced into the hose and before the stopper is released from said handling means.
Claim 16
Independent Claim 119 words
