Abstract
Abstract A filling and emptying means for a flexible sac for holding a product to be dispensed. The means comprises a nozzle having a tubular member with a flange on one end. Said tubular member extends through the wall of said flexible sac with said flange in sealing engagement against the inside of the wall of said flexible sac. The tubular member has a bore therethrough and has an outer end portion with a smaller diameter and an inner end portion having a larger diameter and a beveled shoulder between said smaller and larger diameter portions. A body with which the sac is associated has a bore therein having portions for receiving the smaller and larger diameter portions of said tubular member and has a complementary shoulder between said bore portions which is complementary in shape to said tubular member shoulder against which said shoulder is seated for positively positioning said tubular member in said bore. A collar is preferably provided on the end of the tubular member for preventing withdrawal of the tubular member from the bore in the body.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
203 words
A filling and emptying means for filling and emptying a flexible sac for holding a product to be dispensed, said filling and emptying means comprising a nozzle having a tubular member with a flange on one end of the tubular member and a bore through the tubular member, said tubular member having an outer end portion with a smaller diameter and an inner end portion having a larger diameter and a beveled shoulder between said smaller diameter and larger diameter portions, said shoulder being adapted to seat against a complementary shoulder in a bore in the body with which the flexible sac is to be associated for positively positioning the nozzle in said bore, said flange having on the surface thereof opposite the surface from which said tubular member projects a plurality of projections extending radially from the opening of said bore in said flange, said projections having the ends which are toward the bore spaced from the edge of the bore and having a width about the same as the diameter of the bore and having a height such that the openings between said ends together will have a total cross-sectional area at least equal to the cross-sectional area of the bore.
Claim 2
Dependent Claim
203 words
A filling and emptying means for filling and emptying a flexible sac for holding a product to be dispensed, said filling and emptying means comprising a nozzle having a tubular member with a flange on one end of the tubular member and a bore through the tubular member, said tubular member having an outer end portion with a smaller diameter and an inner end portion having a larger diameter and a beveled shoulder between said smaller diameter and larger diameter portions, said shoulder being adapted to seat against a complementary shoulder in a bore in the body with which the flexible sac is to be associated for positively positioning the nozzle in said bore, said flange having on the surface thereof opposite the surface from which said tubular member projects a plurality of projections extending radially from the opening of said bore in said flange, said projections having the ends which are toward the bore spaced from the edge of the bore and having a width about the same as the diameter of the bore and having a height such that the openings between said ends together will have a total cross-sectional area at least equal to the cross-sectional area of the bore.
Claim 3
Dependent Claim
62 words
A filling and emptying means as claimed in claim 1 in which said tubular member has a collar on the end thereof opposite the flange, the under surface of said collar being adapted to engage the wall of the body to prevent withdrawal of the nozzle under the pressure of a fluid being filled into a flexible sac through said tubular member.
Claim 4
Dependent Claim
29 words
A filling and emptying means as claimed in claim 2 in which said tubular member has an inwardly tapered portion at the outer end thereof just beneath said collar.
Claim 5
Dependent Claim
29 words
A filling and emptying means as claimed in claim 1 in which the end of said tubular member opposite said flange is tapered inwardly to a relatively sharp edge.
Claim 6
Dependent Claim
19 words
A filling and emptying means as claimed in claim 1 in which the tops of said projections are rounded.
Claim 7
Dependent Claim
161 words
In combination, a flexible sac for holding a product to be dispensed, a body with which the flexible sac is associated, and a filling and emptying means for said sac comprising a nozzle having a tubular member with a flange on one end, said tubular member extending through the wall of said flexible sac with said flange in sealing engagement against the inside of the wall of said flexible sac, said tubular member having a bore therethrough and having an outer end portion with a smaller diameter and an inner end portion having a larger diameter and a beveled shoulder between said smaller and larger diameter portions, said body having a bore therein having portions for receiving the smaller and larger diameter portions of said tubular member and having a complementary shoulder between said bore portions which is complementary in shape to said tubular member shoulder against which said shoulder is seated for positively positioning said tubular member in said bore.
Claim 8
Dependent Claim
161 words
In combination, a flexible sac for holding a product to be dispensed, a body with which the flexible sac is associated, and a filling and emptying means for said sac comprising a nozzle having a tubular member with a flange on one end, said tubular member extending through the wall of said flexible sac with said flange in sealing engagement against the inside of the wall of said flexible sac, said tubular member having a bore therethrough and having an outer end portion with a smaller diameter and an inner end portion having a larger diameter and a beveled shoulder between said smaller and larger diameter portions, said body having a bore therein having portions for receiving the smaller and larger diameter portions of said tubular member and having a complementary shoulder between said bore portions which is complementary in shape to said tubular member shoulder against which said shoulder is seated for positively positioning said tubular member in said bore.
Claim 9
Dependent Claim
56 words
The combination as claimed in claim 6 in which said tubular member has a collar on the end thereof opposite the flange, the under surface of said collar engaging the wall of the body to prevent withdrawal of the nozzle under the pressure of a fluid being filled into a flexible sac through said tubular member.
Claim 10
Dependent Claim
37 words
The combination as claimed in claim 7 in whIch said tubular member has an inwardly tapered portion at the outer end thereof just beneath said collar, and said bore in said body has a complementary taper therein.
Claim 11
Dependent Claim
26 words
The combination as claimed in claim 6 in which the end of said tubular member opposite said flange is tapered inwardly to a relatively sharp edge.
Claim 12
Dependent Claim
98 words
The combination as claimed in claim 6 in which said flange has on the surface thereof opposite the surface from which said tubular member projects a plurality of projections extending radially from the opening of said bore in said flange, said projections having the ends which are toward the bore spaced from the edge of the bore and having a width about the same as the diameter of the bore and having a height such that the openings between said ends together will have a total cross-sectional area at least equal to the cross-sectional area of the bore.
Claim 13
Dependent Claim
16 words
The combination as claimed in claim 10 in which the tops of said projections are rounded.
