Abstract
Abstract Mold structure for fabricating fluid-collecting receptacles. The mold structure comprises positive and negative molds, with the former including pin means for effecting both alignment of the molds as well as for forming elongate ports. Thus, mold alignment is assured so as to insure uniform wall thickness of the part to be made, this since both the part as well as the molds forming the part are held strictly on center line. Additionally, the ports or port extensions of the receptacle, in addition to themselves serving a useful purpose in the structure, provide access means whereby alignment pins of the positive mold may be used as guides relative to corresponding apertures in the negative mold.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
136 words
A port-including container-producing mold apparatus including, in combination, unitary, elongate, positive mold means for forming the interior surface of a container and also the interior surfaces of port extensions to be integrally formed with said container; and negative mold means for forming the exterior surfaces of said container and port extensions, said positive and negative mold means being provided with intercooperating elongated pin means and guide aperture means, respectively, for constraining said positive and negative mold means to predetermined, fixed-axis axial movement, whereby to assure desired wall formation of said container, said pin means being integral with said positive mold means and extending parallel to the longitudinal axis of said positive mold means, said negative mold means being relieved about solely a portion of said pin means to form mold cavity means for said port extensions.
Claim 2
Dependent Claim
136 words
A port-including container-producing mold apparatus including, in combination, unitary, elongate, positive mold means for forming the interior surface of a container and also the interior surfaces of port extensions to be integrally formed with said container; and negative mold means for forming the exterior surfaces of said container and port extensions, said positive and negative mold means being provided with intercooperating elongated pin means and guide aperture means, respectively, for constraining said positive and negative mold means to predetermined, fixed-axis axial movement, whereby to assure desired wall formation of said container, said pin means being integral with said positive mold means and extending parallel to the longitudinal axis of said positive mold means, said negative mold means being relieved about solely a portion of said pin means to form mold cavity means for said port extensions.
Claim 3
Dependent Claim
41 words
The apparatus of claim 1 wherein said negative mold means is provided with said guide apertures as said guide aperture means, said pin means forming extension means of said positive mold means extending through and forming interiors of said port extensions.
Claim 4
Dependent Claim
26 words
The structure of claim 2 wherein said negative mold means includes annular, port-extension material-receiving recesses respectively contiguous with and enlarged with respect to said guide apertures.
Claim 5
Dependent Claim
28 words
The structure of claim 2 wherein said pin means are each annularly spaced from the remainder of said positive mold means by an annular, mold-material receiving port-extension groove.
Claim 6
Dependent Claim
28 words
The structure of claim 3 wherein said pin means are each annularly spaced from the remainder of said positive mold means by an annular, mold-material receiving port-extension groove.
Claim 7
Dependent Claim
55 words
Container-producing apparatus including, in combination an elongate positive mold having integral, axially outwardly extending, port-forming guide pins parallel to the longitudinal axis of said positive mold; and a negative mold having guide apertures slideably receiving said guide pins, said negative mold also being provided with exterior port-surface-forming recesses contiguous with and circumscribing said guide apertures.
Claim 8
Dependent Claim
55 words
Container-producing apparatus including, in combination an elongate positive mold having integral, axially outwardly extending, port-forming guide pins parallel to the longitudinal axis of said positive mold; and a negative mold having guide apertures slideably receiving said guide pins, said negative mold also being provided with exterior port-surface-forming recesses contiguous with and circumscribing said guide apertures.
Claim 9
Dependent Claim
19 words
The structure of claim 6 wherein said positive mold is provided with annular port-forming grooves circumscribing said guide pins.
