Abstract
Abstract A roller bottle is disclosed having a plurality of sections which may be bonded after their interior surfaces have been treated to enhance cell adhesion. The bottle may be plastic so that it is disposable, and has a pair of serrated circumferential edges to improve traction when in contact with rollers on a standard cell production roller apparatus. It includes a bottom cap, a cylindrical section, a top cap having a threaded neck, and a screw cap. The bottom and top caps include the serrated edges which enable the bottle to roll rather than slip on a roller apparatus. A method for the use of the bottles is also disclosed wherein a roller apparatus is able to rotate a large number of stacked bottles.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
54 words
A method for culturing cells within a roller bottle having an interior surface adapted for cell adhesion and an exterior surface including at least one serrated portion along its circumference comprising the steps of contacting said serrated portion with rollers of a roller apparatus and rotating said rollers whereby the bottle rotates without slipping.
Claim 2
Independent Claim
54 words
A method for culturing cells within a roller bottle having an interior surface adapted for cell adhesion and an exterior surface including at least one serrated portion along its circumference comprising the steps of contacting said serrated portion with rollers of a roller apparatus and rotating said rollers whereby the bottle rotates without slipping.
Claim 3
Dependent Claim
33 words
A method as described in claim 1 wherein at least two serrated portions are provided on the exterior surface of the bottle, said serrated portions protruding from the exterior surface of the bottle.
Claim 4
Dependent Claim
87 words
A method as described in claim 1 wherein at least two bottles having at least one serrated portion are positioned upon rollers of a roller apparatus such that the serrated portions contact the rollers, and a third bottle having at least one serrated portion is stacked upon said at least two bottles such that the serrated portion of the third bottle meshes with the serrations of the bottles upon the rollers, whereby the rotation of the bottles upon the rollers also causes the third bottle to rotate.
