Abstract
Abstract A balanced package tube is provided by initially positioning the coupling element and closure element so that a limited access opening is provided for the longitudinally extending circumferentially spaced recesses in each. After determining the unbalance, the weight bodies are inserted in the appropriate recesses and the access openings closed either by moving the whole element into the hollow body or by moving a hub relative to the recess-defining insert.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
100 words
A balanced package tube comprising a cylindrical hollow body; a coupling element mounted in a coupling end of said hollow body having a plurality of circumferentially spaced apart longitudinally extending recesses within said hollow body for receiving weight bodies therein and a hub closing off said recesses to the interior of said hollow body; and a closure element mounted in a closure end of said hollow body having a plurality of circumferentially spaced apArt longitudinally extending recesses within said hollow body for receiving weight bodies therein and a hub closing off said recesses to the interior of said hollow body.
Claim 2
Dependent Claim
100 words
A balanced package tube comprising a cylindrical hollow body; a coupling element mounted in a coupling end of said hollow body having a plurality of circumferentially spaced apart longitudinally extending recesses within said hollow body for receiving weight bodies therein and a hub closing off said recesses to the interior of said hollow body; and a closure element mounted in a closure end of said hollow body having a plurality of circumferentially spaced apArt longitudinally extending recesses within said hollow body for receiving weight bodies therein and a hub closing off said recesses to the interior of said hollow body.
Claim 3
Dependent Claim
41 words
A balanced package tube as set forth in claim 1 wherein at least one of said coupling element and said closure element includes an insert slidably mounted in said hollow body and rigidly connected to said hub to define said recesses.
Claim 4
Dependent Claim
52 words
A balanced package tube as set forth in claim 1 wherein at least one of said coupling element and said closure element includes an insert mounted in said hollow body, said hub being slidably mounted within said insert to selectively open and close said recesses to the interior of said hollow body.
Claim 5
Dependent Claim
68 words
A balanced package tube as set forth in claim 1 wherein at least one of said coupling element and said closure element includes an insert mounted in said hollow body, and said hub includes a first hub part rigidly connected to said insert and a second hub part axially slidably mounted in said insert to selectively open and close said recesses to the interior of said hollow body.
Claim 6
Dependent Claim
37 words
A balanced package tube as set forth in claim 1 wherein at least one of said coupling element and said closure element includes an insert having a plurality of longitudinally extending circumferentially spaced ribs defining said recesses.
Claim 7
Independent Claim
128 words
A method of making a balanced mountable package tube having a cylindrical hollow body, a coupling element having circumferentially spaced recesses inserted into one end of the hollow body and a closure element having circumferentially spaced recesses inserted into the opposite end, each element having at least one slidable hub defining an inner limitation of the recesses therein, said method comprising the steps of positioning the hub of each element relative to the hollow body to leave an opening sufficient only to permit insertion of weight bodies into the recesses of each element; thereafter determining the unbalance of the package tube; subsequently inserting a determined number of weight bodies into determined recesses of the elements; and thereafter moving each hub to close the recesses within the hollow body.
Claim 8
Independent Claim
128 words
A method of making a balanced mountable package tube having a cylindrical hollow body, a coupling element having circumferentially spaced recesses inserted into one end of the hollow body and a closure element having circumferentially spaced recesses inserted into the opposite end, each element having at least one slidable hub defining an inner limitation of the recesses therein, said method comprising the steps of positioning the hub of each element relative to the hollow body to leave an opening sufficient only to permit insertion of weight bodies into the recesses of each element; thereafter determining the unbalance of the package tube; subsequently inserting a determined number of weight bodies into determined recesses of the elements; and thereafter moving each hub to close the recesses within the hollow body.
