Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
104 words
An improved attaching means for permanently attaching a flexible tube to a stub port of a container of the type wherein an end of the tube is fitted over the stub port, said attaching means comprising a tight-fitting resilient ring fitted over the tube end and over the stub port sealing the tube end against the stub port, and a retainer cap fitted over the ring, said retainer cap being rigidly connected to said container, said retaining cap and ring resiliently squeezing the tube around the stub port, said retainer cap including an inwardly turned lip for preventing axial movement of said resilient ring.
Claim 2
Dependent Claim
104 words
An improved attaching means for permanently attaching a flexible tube to a stub port of a container of the type wherein an end of the tube is fitted over the stub port, said attaching means comprising a tight-fitting resilient ring fitted over the tube end and over the stub port sealing the tube end against the stub port, and a retainer cap fitted over the ring, said retainer cap being rigidly connected to said container, said retaining cap and ring resiliently squeezing the tube around the stub port, said retainer cap including an inwardly turned lip for preventing axial movement of said resilient ring.
Claim 3
Dependent Claim
19 words
The improved attaching means set forth in claim 1, wherein said tube end is expansion fit over said port.
Claim 4
Dependent Claim
19 words
The improved attaching means set forth in claim 2, wherein said container and tube are formed of different materials.
Claim 5
Dependent Claim
20 words
The improved attaching means set forth in claim 2, wherein said ring extends past the end of the stub port.
Claim 6
Dependent Claim

Claim 10
Dependent Claim
137 words
An improved attaching means for permanently attaching a flexible plastic tube to a plastic stub port of a container, the improvement comprising, in combination: said tube end being expansion fit over said port to form a tight frictional engagement with said port; a tight-fitting resilient ring fitted over said tube end and over the stub port sealing the tube end against the stub port, said ring extending past the end of said stub port; and a retainer cap fitted over the ring, said retainer cap having an inwardly turned lip at its upper end retaining the ring, one of said container and stub port being provided with an abutment, and said cap having an outwardly turned flange seated against and bonded to said abutment, said retaining cap and ring resiliently squeezing the tube around the stub port.
Claim 11
Dependent Claim
137 words
An improved attaching means for permanently attaching a flexible plastic tube to a plastic stub port of a container, the improvement comprising, in combination: said tube end being expansion fit over said port to form a tight frictional engagement with said port; a tight-fitting resilient ring fitted over said tube end and over the stub port sealing the tube end against the stub port, said ring extending past the end of said stub port; and a retainer cap fitted over the ring, said retainer cap having an inwardly turned lip at its upper end retaining the ring, one of said container and stub port being provided with an abutment, and said cap having an outwardly turned flange seated against and bonded to said abutment, said retaining cap and ring resiliently squeezing the tube around the stub port.
Claim 12
Independent Claim
93 words
A method for permanently attaching a flexible plastic tube to a plastic stub port of a container of the type wherein the container and/or the stub port is provided with an abutment, the improvement comprising the steps of: fitting an end of the flexible plastic tube over the stub port; fitting a resilient ring over the tube end and over the stub port to seal the tub end against the stub port; fitting a plastic retainer cap having an outwardly turned flange over the ring; and bonding said retainer cap to said abutment.
Claim 13
Independent Claim
93 words
