Aerosol manifold and method of its fabrication
View Patent ↗An improved manifold for an aerosol system may include a valve interface ( 120 ) capable of flexing to fit with a valve stem of an aerosol system and form a seal and methods for making a manifold may include a gate ( 106 ) positioned to improve contact between steel defining a fluid flow path in the manifold.
1. A manifold, comprising:
a nozzle at a first end of the manifold;
a valve interface at a second end of the manifold opposite the nozzle;
a manifold wall connected to and extending from the nozzle to the valve interface and defining a fluid flow path in communication with the nozzle and valve interface; and
a wherein the valve interface comprises:
an outward tapered portion extending from a portion of the manifold wall opposite the nozzle; and
an inward tapered portion extending from the outward tapered portion to form an opening in the valve interface.
2. The manifold of claim 1 , wherein the fluid flow path comprises a vertical flow path portion and a substantially horizontal flow path portion.
3. A valve interface of an aerosol manifold, comprising:
an outward tapered portion extending from a manifold wall; and
an inward tapered portion extending from the outward tapered portion to form an opening for the aerosol manifold.
4. The valve interface of claim 3 , further comprising a thick portion at the interface of the outward tapered portion and the inward tapered portion.
5. The valve interface of claim 3 , wherein the outward tapered portion is thicker than the inward tapered portion.
6. The valve interface of claim 3 , further comprising a thin portion at a termination of the inward tapered portion.
7. The valve interface of claim 3 , further comprising an outward tapered skirt extending from the inward tapered portion.
8. The valve interface of claim 3 , wherein the outward tapered portion and inward tapered portion are formed from a molded resin material.
9. The valve interface of claim 3 , wherein a portion of the inward tapered portion is configured to seal against a valve stem.
10. The valve interface of claim 6 , wherein the thin portion is configured to seal a valve stem.
11. The valve interface of claim 7 , wherein the outward tapered skirt comprises an opening at an end of the outward tapered skirt larger than the opening formed by the inward tapered portion.
12. The manifold of claim 1 , further comprising an outward tapered skirt flaring outwards from the inward tapered portion.
13. The manifold of claim 1 , further comprising a thick portion at an interface of the outward tapered portion and the inward tapered portion, wherein the thick portion is about 0.020 inches thick.
14. The manifold of claim 1 , further comprising a circumferential thin portion at the opening, wherein the inward tapered portion extends from the outward tapered portion to the thin portion.
