Abstract
A locking aerosol dispenser with a dome, a top thermoplastic elastomeric button member molded over a dome opening, and a base lock member. The rotatable base lock rotates from locked to unlocked position with respect to the essentially non-rotatable dome. A product channel member in the dome is held by the elastomeric button, and not otherwise attached to the dome. The base lock has an upstanding bridge with unlocking slots within which extend fingers on the product channel member when the dispenser is unlocked and actuated. The base lock is not attached to the aerosol valve mounting cup. The dome is attached to the base lock member and the aerosol valve mounting cup, the dome capturing the base lock member between the dome and aerosol container.
Claims18
A locking aerosol dispenser for mounting on a product container having an aerosol valve with mounting cup and valve stem mounted at the top of the container, comprising in combination:
- a rotatable base lock member rotatable between an on-unlocked position and an off-locked position, and having a central opening, a side wall, a top peripheral surface, and a bridge member extending upwardly above and across said central opening, said bridge member including a central valve stem opening and slots adjacent thereto;
- said rotatable base lock member being unattached to said mounting cup to facilitate ease of rotation;
- a non-rotatable dome member mounted on and extending upward above said rotatable base lock member, said dome member having a flange for attachment of said dome member to the mounting cup upon mounting of the locking aerosol dispenser on the product container, said dome member capturing the rotatable base lock member between the dome member and the product container upon mounting the locking aerosol dispenser on the product container;
- said dome member further including a product channel member having a nozzle at a forward position for dispensing product, a valve stem engaging portion at a lower position, and a product channel therebetween including an upstanding conduit extending upwardly from the stem engaging portion and a conduit leading toward the nozzle;
- said product channel member having lateral finger extensions on its side wall for fitting within said bridge slots when the base lock member is rotated to the on-unlocked position and the product channel member is depressed to actuate the valve, said lateral finger extensions being blocked by the bridge member when the base lock member is rotated to the off-locked position to prevent depression of the product channel member;
- and
- said dome including a button member at the top of the product channel for user depression thereof.
A locking aerosol dispenser for mounting on a product container having an aerosol valve with mounting cup and valve stem mounted at the top of the container, comprising in combination:
- a rotatable base lock member rotatable between an on-unlocked position and an off-locked position, and having a central opening, a side wall, a top peripheral surface, and a bridge member extending across said central opening, said bridge member including a central valve stem opening and slots adjacent thereto;
- a non-rotatable dome member mounted on and extending upward above said rotatable base lock member, said dome member capturing the rotatable base lock member between the dome member and the product container upon mounting the locking dispenser on the product container;
- said dome member further including a product channel member having a nozzle at one position for dispensing product, a stem engaging portion at another position, and a product channel therebetween including an upstanding conduit extending upwardly from the stem engaging portion and a conduit leading toward the nozzle;
- said product channel member having lateral finger extensions on its side wall for fitting within said bridge slots when the base member is rotated to the on-unlocked position and the product channel member is depressed to actuate the valve, said lateral finger extensions being blocked by the bridge member when the base lock member is rotated to the off-locked position to prevent depression of the product channel member;
- said dome including a button member at the top of the product channel for user depression thereof, said button comprising a thermoplastic elastomeric member molded onto the top of the product channel member and over an opening in the top of the dome and onto dome surfaces adjacent the opening in the top of the dome.
