Abstract
A retaining apparatus configured to couple to a valve stem of an aerosol container and to interface with a dispenser to actuate the valve stem. The apparatus includes a body portion having an internal bore configured to receive a valve stem. The internal bore has an internal diameter. A wall has a thickness defined between the internal bore and an exterior surface of the body portion. The body portion further includes an aperture having a diameter selected to avoid atomization of fluid travelling through the aperture. The wall thickness is selected to prevent collapsing of the wall when the valve stem is actuated.
Claims20
A dispenser, comprising:
- a retaining apparatus including a body portion having an internal bore, the internal bore defining an axial portion having a length in an axial direction and an internal diameter, a tapered surface adjacent the axial portion with a length in the axial direction smaller than the axial portion length, and a wall having a thickness defined between the internal bore and an exterior surface of the body portion, wherein the thickness of the wall is between 1.45 mm and 1.75 mm;
- and
- an aerosol container having a valve stem, wherein a portion of the valve stem exterior to the aerosol container has a greatest diameter, and wherein the greatest diameter of the valve stem is smaller than the internal diameter of the internal bore,
- wherein a distal end of the portion of the valve stem exterior to the aerosol container is seated within the internal bore.
A dispenser, comprising:
- a retaining apparatus including a body portion having an internal bore, the internal bore defining an axial portion having a length in an axial direction and an internal diameter, the internal bore further defining a tapered surface adjacent the axial portion with a length in the axial direction smaller than the axial portion length;
- an aperture in the body portion having a diameter between 0.6 mm and 1.2 mm;
- and
- an aerosol container having a valve stem, wherein a portion of the valve stem exterior to the aerosol container has a greatest diameter, and wherein the greatest diameter of the valve stem is smaller than the internal diameter of the internal bore,
- wherein a distal end of the portion of the valve stem exterior to the aerosol container is seated within the internal bore.
A dispenser, comprising:
- a retaining apparatus including a body portion defined between an exterior surface and an internal bore, the internal bore defining an axial portion having a length in an axial direction and an internal diameter and a tapered surface adjacent the axial portion with a length in the axial direction smaller than the axial portion length, the body portion further comprising an upper surface and a frustoconical surface between the upper surface and the exterior surface;
- and
- an aerosol container having a valve stem, wherein a portion of the valve stem exterior to the aerosol container has a greatest diameter, and wherein the greatest diameter of the valve stem is smaller than the internal diameter of the internal bore,
- wherein a distal end of the portion of the valve stem exterior to the aerosol container is seated within the internal bore, and
- wherein the frustoconical surface is configured to interface with an angled or rounded surface on a dispenser in order to actuate the valve stem.
