Bulk containers

Claim 2

A bulk container having an outer container, a flexible baglike inner container for holding liquid to be stored, a socket member having at least on opening therethrough, said socket member being fastened securely to the inner container in such manner that a portion of the inner container extends across the inner end of the opening through the socket member so as to constitute a frangible diaphragm, wherein said socket member has a neck portion of noncircular shape which engages a corresponding noncircular aperture in the wall of said outer container for securing said socket member against rotational and linear movement relative to said outer container; said opening through said socket member being adapted to receive in leakage-free manner a tap for dispensing the contents of the inner container after the frangible diaphragm has been broken.

Claim 3

A bulk container having an outer container, a flexible baglike inner container for holding liquid to be stored, a socket member having at least one opening therethrough, said socket member being fastened securely to the inner container in such manner that a portion of the inner container extends across the inner end of the opening through the socket member so as to constitute a frangible diaphragm, wherein said socket member has in its outer surface a noncircular seating to accommodate a noncircular flange on the tap whereby the tap, when fully engaged with the socket member, is heLd against turning; said opening through said socket member being adapted to receive in leakage-free manner a tap for dispensing the contents of the inner container after the frangible diaphragm has been broken, and securing means for securing said socket member against rotational and linear movement relative to said outer container.

Claim 4

A bulk container having an outer container, a flexible baglike inner container for holding liquid to be stored, a socket member having at least one opening therethrough, said socket member being fastened securely to the inner container in such manner that a portion of the inner container extends across the inner end of the opening through the socket member so as to constitute a frangible diaphragm, wherein said socket member has in its outer surface a noncircular seating to accommodate a noncircular flange on the tap whereby the tap, when fully engaged with the socket member, is heLd against turning; said opening through said socket member being adapted to receive in leakage-free manner a tap for dispensing the contents of the inner container after the frangible diaphragm has been broken, and securing means for securing said socket member against rotational and linear movement relative to said outer container.

Claim 5

A bulk container having an outer container, an inner container in the form of a flexible bag for holding liquid to be stored, a socket member fitted to the outer container and engaged with the inner container at a location at which a tap can be fitted so that the tap will engage in the socket member and penetrate into the inner container to permit the flow of liquid therefrom through the tap, the socket member having an inner end which engages with the inner container in a substantially leakproof manner to prevent leakage of liquid therefrom to the interior of the outer container, and an integral locating pin on said socket member engaging in a hole in the wall of the outer container to prevent rotation of said socket member relative thereto.

Claim 6

A bulk container having an outer container, an inner container in the form of a flexible bag for holding liquid to be stored, a socket member fitted to the outer container and engaged with the inner container at a location at which a tap can be fitted so that the tap will engage in the socket member and penetrate into the inner container to permit the flow of liquid therefrom through the tap, the socket member having an inner end which engages with the inner container in a substantially leakproof manner to prevent leakage of liquid therefrom to the interior of the outer container, and an integral locating pin on said socket member engaging in a hole in the wall of the outer container to prevent rotation of said socket member relative thereto.

Claim 7

A bulk container according to claim 3 wherein said socket member has a circumferential bead near said inner end which tightly engages with a ring member which is within said inner container, whereby a part of said inner container is clamped therebetween across said inner end to form a frangible diaphragm.

Claim 8

A bulk container having an outer container, an inner container in the form of a flexible bag for holding liquid to be stored, a socket member fitted in the outer container and engaged with the inner container at a location whereat a tap is to be fitted so that the tap will engage in the socket member and penetrate into the inner container, the tap having at its inner end a probe of somewhat conical shape with a least one opening therethrough, at an intermediate position in its length a flange to engage nonrotatably in said socket member, and at its outer end a turncock to control the flow of liquid from the inner container through the tap, and said socket member engaging with the inner container in a substantially leakproof manner to prevent leakage of liquid therefrom to the interior of the outer container.

Claim 9

A bulk container having an outer container, an inner container in the form of a flexible bag for holding liquid to be stored, a socket member fitted in the outer container and engaged with the inner container at a location whereat a tap is to be fitted so that the tap will engage in the socket member and penetrate into the inner container, the tap having at its inner end a probe of somewhat conical shape with a least one opening therethrough, at an intermediate position in its length a flange to engage nonrotatably in said socket member, and at its outer end a turncock to control the flow of liquid from the inner container through the tap, and said socket member engaging with the inner container in a substantially leakproof manner to prevent leakage of liquid therefrom to the interior of the outer container.

Claim 10

A bulk container according to claim 5 wherein said opening in said probe extends substantially longitudinally of said tap.

Claim 11

A tap for use with a bulk container for liquids comprising a body portion having an outlet therefrom, a neck part at the inner end of said body portion for engagement in a support, an external flange of noncircular shape at the inner end of said body portion for engagement in a seating, a probe of tapered shape at the inner end of the neck part, said probe having at least one opening therethrough to permit the flow of liquid into the interior of the neck part and body portion, and a turncock engaged in said body portion, said turncock having an opening to register with the outlet from the body portion when said turncock is turned to the ''on'' position.

Claim 12

A tap for use with a bulk container for liquids comprising a body portion having an outlet therefrom, a neck part at the inner end of said body portion for engagement in a support, an external flange of noncircular shape at the inner end of said body portion for engagement in a seating, a probe of tapered shape at the inner end of the neck part, said probe having at least one opening therethrough to permit the flow of liquid into the interior of the neck part and body portion, and a turncock engaged in said body portion, said turncock having an opening to register with the outlet from the body portion when said turncock is turned to the ''on'' position.

Claim 13

A tap according to claim 2 wherein there are a plurality of openings through the probe and said openings extend substantially longitudinally of the tap.

Claim 14

A tap according to claim 7 wherein the turncock has adjacent its inner end an external embossment engaged in a groove in the inner wall of the body portion, said embossment being effective to hole the turncock against linear movement.
