Abstract

A roller bottle is provided with provision for increased internal surface area for cell growth by the use of a foamed, textured or woven liner or sleeve inserted into the bottle prior to use. The sleeve may be used in a single use roller bottle or a multiple use roller bottle. With the latter, the sleeve is discarded, the bottle sterilized, and a new sleeve or liner is inserted. The interstices of the foamed, textured or woven surface has the effect of increasing the actual surface area available for culturing cells in each single roller bottle, thus making the roller bottle of the invention cost effective.

Claims

1. A roller bottle for cell growth culturing, characterized by

(a) a substantially cylindrical housing open at both ends, and defining a hollow cell growth chamber in said roller bottle;

(b) a bottom end cap for closing one end of said housing;

(c) a top cap for closing the end of said housing opposite said bottom cap;

(d) an opening positioned centrally of said top cap for gaining access to said cell growth chamber;

(e) a closure cap for closing said opening in said top cap;

(f) first cooperating joining means on said housing and said bottom end cap for joining said bottom end cap to said housing;

(g) second cooperating joining means on said housing and said top cap for joining said top cap to said housing; and

(h) a liner comprised of a single layer sleeve for lining the walls of said hollow growth chamber;

(i) said liner comprised of a material presenting a textured uneven surface to increase the effective surface area for cell growth in said chamber.

2. The roller bottle of claim 1, further characterized by

(a) said roller bottle is a single-use roller bottle;

(b) said liner is inserted into said chamber prior to the closing of at least one of the open ends thereof; and

(c) said first and second joining means are permanent connections.

3. The roller bottle of claim 1, further characterized by

(a) said roller bottle is a repeated use roller bottle;

(b) a plurality of said liners are inserted sequentially into said chamber for each use of said roller bottle; and

(c) said first and second joining means are disconnectable for removing one or both of said bottom end cap and said top end cap.

4. The roller bottle of claim 1, further characterized by

(a) said liner is selected from the group consisting of microporous polyvinyl chloride, microporous polyethylene terephthalate, microporous polypropylene, microporous ultrahigh molecular weight polyethylene, microporous high density polyethylene, microporous styrene acrylonitrile, foamed polyurethane-ether, 40 pound basis weight medical grade paper, 42 pound basis weight medical grade paper, and spun-bonded resin.

5. The roller bottle of claim 2, further characterized by

(a) said roller bottle is comprised of a material selected from the group consisting of microporous polyvinyl chloride, microporous polyethylene terephthalate, microporous polypropylene, microporous ultrahigh molecular weight polyethylene, microporous high density polyethylene, microporous styrene acrylonitrile, foamed polyurethane-ether, 40 pound basis weight medical grade paper, 42 pound basis weight medical grade paper, and spun-bonded resin.

6. The roller bottle of claim 3, further characterized by

(a) said roller bottle is comprised of a material selected from the group consisting of glass, stainless steel and thermoplastic resin.

7. The roller bottle of claim 1, further characterized by

(a) each of said top cap and bottom cap having a serrated rim enabling said roller bottle to provide cooperating relative rotation with the serrated rims of other roller bottles in a roller bottle apparatus.

8. A liner for use in a roller bottle, characterized by

(a) a cylindrical liner body comprised of a single layer for lining the internal surface of a roller bottle;

(b) said body defining a hollow liner chamber therein;

(c) the walls of said hollow liner chamber being textured and uneven for presenting an increase in effective cell growth surface area in said hollow liner chamber; and

(d) said liner being inserted into a roller bottle prior to final closure thereof.

9. The liner of claim 8, further characterized by

(a) one end of said cylindrical liner body being closed;

and

(b) said closed end of said cylindrical liner body covering the bottom end of a roller bottle into which said liner body is inserted.

10. The liner of claim 8, further characterized by

(a) said liner comprised of a material selected from the group consisting of microporous polyvinyl chloride, microporous polyethylene terephthalate, microporous polypropylene, microporous ultrahigh molecular weight polyethylene, microporous high density polyethylene, microporous styrene acrylonitrile, foamed polyurethane-ether, 40 pound basis weight medical grade paper, 42 pound basis weight medical grade paper, and spun-bonded resin.
