Abstract
An aerosol spray can and selectively-operable valve mechanism for dispensing the contents of the can to an environment are assembled to one another in operable relation using an adaptor structure which comprises an element snap-fit mounted to the aerosol can and a further element snap-fit mounted or otherwise affixed to the valve mechanism. The elements are provided with mating screw threads, which permit the assembly to be readily and securely effected. The adaptor elements are moulded parts constructed to be resiliently flexible to a degree to assist in mounting and demounting from the element to which it is to be attached and yet to resist such flexure when assembled together.
Claims15
An adaptor device for connecting an aerosol spray can with a selectively-operable valve mechanism for dispensing the contents of said aerosol can, which comprises:
- first and second elements,
- said first element having a right-cylindrical portion having means for mounting said first element to a cylindrical upstream portion of the valve mechanism,
- said second element having a right cylindrical portion and having means on an external wall of said right cylindrical portion thereof for snap-fit mounting said second element within an undercut rim of the aerosol can and having a right cylindrical portion,
- each said first and second elements being provided with screw threads which mate with each other to permit said first and second elements to be screw-threadedly assembled and disassembled,
- said screw threads on said first element being formed on a exterior wall of said right-cylindrical portion thereof, and said screw thread on said second cylindrical portion being formed on a interior wall of said right-cylindrical portion thereof.

An adaptor device for connecting an aerosol spray can with a selectively-operable valve mechanism for dispensing the contents of said aerosol can, which comprises:
- first and second elements,
- said first element having a right cylindrical portion having means for mounting said first element to a cylindrical upstream portion of the valve mechanism,
- said second element having a right cylindrical portion and having means on an external wall of said right cylindrical portion thereof for snap-fit mounting of said second element within an undercut rim of the aerosol can and having a right cylindrical portion,
- each said first and second elements being provided with screw threads which mate with each other to permit said first and second elements to be screw-threadedly assembled and disassembled,
- said screw threads on said first element being formed on an exterior wall of said right-cylindrical portion thereof and said screw threads on said second cylindrical portion being formed on an interior wall of said right-cylindrical portion thereof,
- said screw threads being in the form of a continuous bevelled thread extending throughout the longitudinal dimension of said right cylindrical portion of said first element and in the form of a continuous bevelled thread of complimentary shape to the bevelled screw thread formed on said first element extending throughout the longitudinal dimension of said right cylindrical-portion of said second element,
- said first element and said second element each having a radially-directed flange element extending outwardly from an upper extremity of said right-cylindrical portion of each of said first and second elements, whereby said flange elements abut each other when said elements are fully screw-threadedly joined to each other.

An adaptor device for connecting an aerosol spray can with a selectively-operable valve mechanism for dispersing the contents of said aerosol can, which comprises:
- first and second elements,
- said first element having means for mounting same to a cylindrical upstream portion of the valve mechanism and having a right cylindrical portion,
- said second element having means for mounting same to an undercut rim of the aerosol can and having a right-cylindrical portion,
- each said first and second elements being provided with screw threads which mate each other to permit screw-threaded joining and unjoining of said first and second elements,
- said first element and said second element each having a radially-directed flange element extending outwardly from an upper extremity of said right-cylindrical portion of each of said first and second elements, whereby said flange elements abut each other when said elements are fully screw-threadedly joined to each other,
- said first element including a further cylindrical portion thereof extending from the outer radial extremity of the radially-directed flange thereof in an axial direction opposite to direction of axial extension of the first-mentioned right-cylindrical portion thereof to engage an outer cylindrical wall of said valve mechanism, and
- said further cylindrical portion having diametrically-opposite slots formed therein to receive therethrough radially-directed mounting elements of the valve mechanism, whereby said first element is locked against rotation relative to the valve mechanism by the extension of the radially-directed mounting elements through the diametrically-opposed slots.

An adaptor device for connecting an aerosol spray can with a selectively-operable valve mechanism for dispensing the contents of said aerosol can, which comprises:
- first and second elements,
- said first element having a right cylindrical portion having means for mounting said first element to a cylindrical upstream portion of the valve mechanism,
- said second element having a right cylindrical portion and having means on an external wall of said right cylindrical portion thereof for snap-fit mounting of said second element within an undercut rim of the aerosol can and having a right cylindrical portion,
- each said first and second elements being provided with screw threads which mate with each other to permit said first and second elements to be screw-threadedly assembled and disassembled,
- said screw threads on said first element being formed on an exterior wall of said right-cylindrical portion thereof and said screw threads on said second cylindrical portion being formed on an interior wall of said right-cylindrical portion thereof,
- said snap fit means for mounting said second element within an undercut rim of the aerosol can comprising a groove formed on said exterior wall of said right-cylindrical portion thereof to receive in snap-fitting relationship therewith a continuous bulbous head of the rim defining the undercut,
- said means of mounting said first element to a cylindrical upstream portion of the valve mechanism comprising a continuous protrusion formed on an inner wall of said right-cylindrical portion thereof to be received in snap-fit relationship with a complimentary continuous groove formed in the cylindrical upstream portion of the valve mechanism,
- said right-cylindrical portion of said first element having at least one slot formed therein extending from a closed end at said radially-extending flange thereof to an open end at the lower extremity of said right cylindrical portion thereof, to permit outward resilient flexure of said right-cylindrical portion thereof to assist in mounting said first element to and demounting said first element from the valve mechanism when the first element is out of screw-threaded assembly with said second element.
