Abstract

Abstract This invention relates to an integral multi-compartment combination package and stirrer device. A hollow tubular body is bonded together with end caps and one or more compartment separators are bonded inside the hollow tubular body. A die cut slot in the tubular body forms an opening to each compartment and the contents are contained in the compartments with a tear-away or perforated sealable tab affixed atop of each compartment emptying slot. The user can remove the tab to empty the contents of one or more of the additives into a beverage and then utilize this package itself to stir the additives into a hot or cold beverage. Other conventional opening methods may be used as alternatives to the tear-away tab method.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 273 words
An integral multi-compartment combination package and stirrer device of flexible material comprising: A hollow tubular body having opposed elongated sides bonded together to form said tubular body, two end caps each having the cross sectional shape of the finished combination package and stirrer device with a flanged lip around the perimeter at a right angle to the flat surface of said end cap, one or more compartment separators similar to said end cap, one said end cap inserted into said tubular body with end cap positioned with flat surface of end cap at right angle to long axis of said tubular body with outside surfaces of flanged lip of said end cap bonded to inside surface of said tubular body at one end or tubular body, said compartment separators inserted into said tubular body with compartment separators positioned with flat surface of compartment separators at right angle to long axis of said tubular body with outside surface flanged lip of said compartment separators bonded to inside surface of said tubular body at a distance from first bonded end cap to form a compartment within the said tubular body, second end cap inserted into tubular body at remaining open end of said tubular body and affixed to tubular body indentical to first bonded end cap, said hollow tubular body having a die cut slot removed or perforated compartment emptying slot cut at one end of each compartment formed in said tubular body for removal of compartment contents, perforated or tear-away sealable tabs affixed atop of each said compartment emptying slot and said tabs are removable from said tubular body to empty contents of compartment.
Claim 2
Dependent Claim 273 words
An integral multi-compartment combination package and stirrer device of flexible material comprising: A hollow tubular body having opposed elongated sides bonded together to form said tubular body, two end caps each having the cross sectional shape of the finished combination package and stirrer device with a flanged lip around the perimeter at a right angle to the flat surface of said end cap, one or more compartment separators similar to said end cap, one said end cap inserted into said tubular body with end cap positioned with flat surface of end cap at right angle to long axis of said tubular body with outside surfaces of flanged lip of said end cap bonded to inside surface of said tubular body at one end or tubular body, said compartment separators inserted into said tubular body with compartment separators positioned with flat surface of compartment separators at right angle to long axis of said tubular body with outside surface flanged lip of said compartment separators bonded to inside surface of said tubular body at a distance from first bonded end cap to form a compartment within the said tubular body, second end cap inserted into tubular body at remaining open end of said tubular body and affixed to tubular body indentical to first bonded end cap, said hollow tubular body having a die cut slot removed or perforated compartment emptying slot cut at one end of each compartment formed in said tubular body for removal of compartment contents, perforated or tear-away sealable tabs affixed atop of each said compartment emptying slot and said tabs are removable from said tubular body to empty contents of compartment.
Claim 3
Dependent Claim 46 words
A multi-compartment combination package and stirrer device as claimed in claim 1 wherein one or more additional compartment separators are inserted and bonded into said tubular body at a further distance from the first bonded compartment separator to form additional compartments within the said tubular body.
Claim 4
Dependent Claim 45 words
A multicompartment combination package and stirrer device as claimed in claim 1 or claim 2 wherein the cross sectional shape of the said end caps, compartment separators, and finished combination package and stirrer can alternatively be triangular, rectangular, octagonal, oval, or the like geometrical shapes.
Claim 5
Dependent Claim 51 words
A multi-comlpartment combination package and stirrer device as claimed in claim 1 which includes a thin layer of a moisture barrier high heat coating to the inside surface of the said tubular body and upon said end caps and upon both surfaces of said compartment separators to provide fluid tight compartments.
Claim 6
Dependent Claim 22 words
A multi-compartment combination package and stirrer device as claimed in claim 1 and 4 wherein the said flexible material is biodegradable paper.
Claim 7
Dependent Claim 31 words
A multi-compartment combination package and stirrer device as claimed in claim 1 wherein the said flexible material is a thermo plastic material and said adhesive contains a resin activated by heat.
Claim 8
Dependent Claim 29 words
A multi-compartment combination package and stirrer device as claimed in claim 1 wherein any conventional tubular opening method may be used as alternative to the tab opening method described.
