Dispensing device container

Claim 2

In a pressurized dispenser comprising the combination of an inner pressurized propellant container and an outer plastic product container having a mouth aperture adapted to receive and retain the inner container by means of a region of interference fit of substantial axial length, said inner container having for a considerable axial length substantially the same peripheral dimension as the outer container mouth aperture, the improvement which comprises having at least one channel establishing a venting passage extending from the interior of the outer container past the region of interference fit, said channel comprising a groove generally parallel to the inner container axis and being formed in one of the contacting surfaces in the region of interference fit.

Claim 3

The improvement of claim 1, and wherein the inner container has an external circumferential bead of slightly larger diameter than the contacting surface of the mouth of the outer container, such that when the inner container is fully inserted the bead acts to sealingly block the exit of said channel in the contacting surfaces.

Claim 4

An aerosol spray dispenser comprising: a. A pressurized aerosol cartridge including a hollow body containing a medium under pressure and an enlarged top on the body, a tube through said hollow body for passing a commodity from a receptacle in which said cartridge is mounted, and a valve for releasing said medium from the body over an upper end of said tube to draw the commodity therewith from the receptacle through the tube; b. A hollow receptacle for receiving the commodity to be dispensed by said cartridge, said receptacle including an open top, a sealed bottom and flexible sidewalls; c. A neck extending from said sidewalls around said open top of the receptacle for receiving said cartridge as it is introduced into the receptacle, said neck including a topmost portion for loosely receiving the lower end and central portions of said hollow body and for tightly receiving and holding said enlarged top portion as said cartridge is inserted downwardly into said receptacle, and a lower portion adjacent said topmost portion for tightly receiving, guiding, and supporting said hollow body in said receptacle; and d. An air passageway in said lower neck portion for passing air from the receptacle to atmosphere as said cartridge is introduced into said receptacle to thereby prevent the buildup of undesired pressures in said receptacle, and for closing when said cartridge is seated in said receptacle.

Claim 5

An aerosol spray dispenser comprising: a. A pressurized aerosol cartridge including a hollow body containing a medium under pressure and an enlarged top on the body, a tube through said hollow body for passing a commodity from a receptacle in which said cartridge is mounted, and a valve for releasing said medium from the body over an upper end of said tube to draw the commodity therewith from the receptacle through the tube; b. A hollow receptacle for receiving the commodity to be dispensed by said cartridge, said receptacle including an open top, a sealed bottom and flexible sidewalls; c. A neck extending from said sidewalls around said open top of the receptacle for receiving said cartridge as it is introduced into the receptacle, said neck including a topmost portion for loosely receiving the lower end and central portions of said hollow body and for tightly receiving and holding said enlarged top portion as said cartridge is inserted downwardly into said receptacle, and a lower portion adjacent said topmost portion for tightly receiving, guiding, and supporting said hollow body in said receptacle; and d. An air passageway in said lower neck portion for passing air from the receptacle to atmosphere as said cartridge is introduced into said receptacle to thereby prevent the buildup of undesired pressures in said receptacle, and for closing when said cartridge is seated in said receptacle.
