Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 107 words
A pellet container comprising an elongated tubular element having a helical slit extending nearly to each end of the tubular element, the tubular element formed of a strip of stiff but resilient plastic material, containing a plurality of pellet-like elements in aligned array with the inner surface of the container frictionally gripping the elements, the resiliency of the material being sufficient normally to maintain the strip in its closed tubular configuration wherein and adjacent edges of the helical slit are in contact, and to yield to manual twisting forces applied thereto for opening the strip in selected locations for dispensing at least one of its pellet-like elements.
Claim 2
Dependent Claim 107 words
A pellet container comprising an elongated tubular element having a helical slit extending nearly to each end of the tubular element, the tubular element formed of a strip of stiff but resilient plastic material, containing a plurality of pellet-like elements in aligned array with the inner surface of the container frictionally gripping the elements, the resiliency of the material being sufficient normally to maintain the strip in its closed tubular configuration wherein and adjacent edges of the helical slit are in contact, and to yield to manual twisting forces applied thereto for opening the strip in selected locations for dispensing at least one of its pellet-like elements.
Claim 3
Dependent Claim 27 words
A container according to claim 1 wherein the tubular element is formed of a material selected from the group consisting of low density polyethylene, nylon or polytetrafluoroethylene.
Claim 4
Dependent Claim 15 words
A container according to claim 2 wherein the tube is formed of low density polyethylene.
Claim 5
Dependent Claim 16 words
A container according to claim 3 having a wall thickness of from 0.015 to 0.030 inches.
Claim 6
Dependent Claim 93 words
In combination, a pellet container comprising a tubular element of stiff but resilient material, the ends of the element being pinched and heat sealed to form end closures, the element having a slit extending helically therealong, the resiliency of the material being sufficient normally to maintain the tubular configuration of the element and to yield to twisting forces applied to the element for opening the slit to dispense the contents of the element, and a plurality of pellets in aligned array and in frictional engagement with the inner surface of the tubular element.
Claim 7
Dependent Claim 93 words
In combination, a pellet container comprising a tubular element of stiff but resilient material, the ends of the element being pinched and heat sealed to form end closures, the element having a slit extending helically therealong, the resiliency of the material being sufficient normally to maintain the tubular configuration of the element and to yield to twisting forces applied to the element for opening the slit to dispense the contents of the element, and a plurality of pellets in aligned array and in frictional engagement with the inner surface of the tubular element.
Claim 8
Dependent Claim 114 words
In combination, a pellet container comprising a tubular element of stiff but resilient material, the element having a slit extending helically therealong, the resiliency of the material being sufficient normally to maintain the element in its tubular configuration and to yield to twisting forces applied thereto for opening the slit in selected locations thereby to open the tube for dispensing its contents, a plurality of pellets in aligned array contained within the tubular element in frictional engagement with the inner surface thereof, the tubular element having circumferential corrugations at various locations along its length and folded back and forth along its length at the locations and means maintaining the element in its folded condition.
Claim 9
Dependent Claim 114 words
In combination, a pellet container comprising a tubular element of stiff but resilient material, the element having a slit extending helically therealong, the resiliency of the material being sufficient normally to maintain the element in its tubular configuration and to yield to twisting forces applied thereto for opening the slit in selected locations thereby to open the tube for dispensing its contents, a plurality of pellets in aligned array contained within the tubular element in frictional engagement with the inner surface thereof, the tubular element having circumferential corrugations at various locations along its length and folded back and forth along its length at the locations and means maintaining the element in its folded condition.
Claim 10
Dependent Claim 15 words
A combination according to claim 6 wherein said last mentioned means is a box-like container.
