Gas bottle valve stem protective sleeve
A protective sleeve for gas bottle valve stems is provided comprised of an elongated tubular body configured to fit on a valve stem. A projection extends from an interior surface of the protective sleeve and is adapted to lockingly engage with an orifice in an opposing surface of the valve stem whereby the sleeve is prevented from being easily removed from the valve stem upon being placed thereover due to engagement of the projection with the orifice. A tear strip is provided within a side surface of the protective sleeve, whereby a portion of the protective sleeve may be removed to permit disengagement of the protective sleeve. A housing may be provided in the protective sleeve for storage of a washer which may be used to provide a seal between a regulator and the valve stem of the gas bottle.
1. A protective sleeve for use in connection with valve stems for gas bottles, said protective sleeve comprised of an elongated four-sided unitary molded tubular body having opposing open ends, said body being of such length as to extend along at least a portion of the length of said valve stem, said sides of said unitary body configured to conform to adjacent faces of said valve stem in protective relationship thereto when said protective sleeve is placed over said valve stem, one or more projections extending from an interior surface of said protective sleeve and adapted to physically engage with an orifice in an opposing surface of said valve stem and in locking engagement therewith, whereby said protective sleeve is prevented from being easily removed from said valve stem upon being placed over an end of said valve stem and moved into sliding locking engagement with said orifice of said valve stem due to engagement of said projection with said orifice; and a tear strip provided within at least a portion of a side surface of said protective sleeve, whereby at least a portion of said side surface of said protective sleeve may be removed by tearing said tear strip so as to permit disengagement and removal of said protective sleeve from said valve stem,
said sleeve further including at least one flange extending laterally outwardly from said sleeve along a plane transverse to a longitudinal axis of said unitary molded tubular body, and
further including a housing for storage of a washer, said housing extending laterally outwardly along a plane transverse to a longitudinal axis of said unitary molded tubular body.
2. The protective sleeve of claim 1 , wherein said tear strip extends longitudinally along at least a portion of a side of said protective sleeve, and is defined laterally by parallel tear lines formed in said side of said protective sleeve.
3. The protective sleeve of claim 1 , comprised of a plastic resin material.
4. The protective sleeve of claim 1 , further including multiple flange members extending laterally outwardly from the bottom of said protective sleeve.

6. The protective sleeve of claim 1 , wherein said housing for storage of said washer includes a removable cover to close said washer within said housing.
7. The protective sleeve of claim 1 , wherein said housing is attached to a portion of said tear strip and serves as a grip member to facilitate tearing of said tear strip.
8. The protective sleeve of claim 7 , wherein said tear strip extends longitudinally along at least a portion of a side of said protective sleeve, and is defined laterally by parallel tear lines formed in said side of said protective sleeve.
9. The protective sleeve of claim 7 , comprised of a plastic resin material.
10. The protective sleeve of claim 7 , wherein said housing for storage of said washer has a portion adapted to physically engage with an interior hole of said washer to hold said washer in place within said housing.
11. The protective sleeve of claim 7 , wherein said housing for storage of said washer includes a removable cover to close said washer within said housing.
12. The protective sleeve of claim 1 , wherein said at least one flange extends laterally outwardly from the bottom of said sleeve.
13. A protective sleeve for use in connection with valve stems for gas bottles, said protective sleeve comprised of an elongated four-sided unitary molded tubular body having opposing open ends, said body being of such length as to extend along at least a portion of the length of said valve stem, said sides of said unitary body configured to conform to adjacent faces of said valve stem in protective relationship thereto when said protective sleeve is placed over said valve stem, one or more projections extending from an interior surface of said protective sleeve and each adapted to physically engage with an orifice in an opposing surface of said valve stem and in locking engagement therewith, whereby said protective sleeve is prevented from being easily removed from said valve stem upon being placed over an end of said valve stem and moved into sliding locking engagement with said orifices of said valve stem due to engagement of said projections with said orifices; and a tear strip provided within at least a portion of a side surface of said protective sleeve, whereby at least a portion of said side surface of said protective sleeve may be removed by tearing said tear strip so as to permit disengagement and removal of said protective sleeve from said valve stem,
said sleeve further including opposing disconnected flanges extending laterally outwardly from said sleeve along a plane transverse to a longitudinal axis of said unitary molded tubular body, and
further including a housing for storage of a washer, said housing extending laterally outwardly along a plane transverse to a longitudinal axis of said unitary molded tubular.
14. The protective sleeve of claim 13 , wherein said tear strip extends longitudinally along at least a portion of a side of said protective sleeve, and is defined laterally by parallel tear lines formed in said side of said protective sleeve.
15. The protective sleeve of claim 13 , comprised of a plastic resin material.
16. The protective sleeve of claim 13 , wherein said housing for storage of said washer has a portion adapted to physically engage with an interior hole of said washer to hold said washer in place within said housing.
