The non-vented automatic dispensing cap is generally formed of a body and a retainer cap. The body is threadably secured to a squeezable tube or container. The retainer cap is attached to the body. A pressure chamber is formed between the body and retainer cap. A piston may also form a wall of the pressure chamber. A coil spring or resilient flange holds a valve seated within a dispensing hole extending through the cap. When the tube is squeezed, the product is forced into the pressure chamber expanding the pressure chamber and unseating the valve, thereby allowing product to exit the dispensing opening. Upright, inverted, vented and unvented versions are disclosed.

What is claimed is: 1. An automatic dispensing cap for use with a container, said automatic dispenser cap comprising: a body connectable to the container, a retainer cap connected with said body and having a chamber therein, a sealing lip slidably resting against an interior surface of said retainer cap, a dispensing hole exiting said dispensing cap, a protrusion selectively sealing and unsealing said dispensing hole, and a spring biased to hold said protrusion to seal said dispensing hole, wherein said automatic dispensing cap has locked position and an unlocked position, wherein, when said automatic dispensing cap is in said locked position, said protrusion is held in said dispensing opening, and wherein said automatic dispensing cap is rotable between said locked position and said unlocked position. 2. The automatic dispensing cap of claim 1, wherein said spring takes the form of at least one resilent flange extending from one of said body and said retainer cap. 3. The automatic dispensing cap of claim 2, wherein said spring takes the form of at least one resilient flange extending from one of said body and said retainer cap. 4. The automatic dispensing cap of claim 3, wherein said resilient flange engages a lug extending from one of said body and said retainer cap. 5. The automatic dispensing cap of claim 1, wherein said dispensing hole passes through a wall of said retainer cap. 6. The automatic dispensing cap of claim 1, wherein said dispensing opening passes through a wall of said retainer cap. 7. The automatic dispensing cap of claim 1, further comprising a piston located at least partially within said retainer cap, said sealing lip and said protrusion extending from said piston. 8. The automatic dispensing cap of claim 1, further comprising a piston located at least partially within said retainer cap, said sealing lip and said protrusion extending from said piston. 9. The automatic dispensing cap of claim 1, further comprising a opening extending through said body from an interior of the container into said chamber. 10. The automatic dispensing cap of claim 1, further comprising a opening extending through said body from an interior of the container into said pressure chamber. 11. The automatic dispensing cap of claim 1, further comprising a vent opening extending through said body into said chamber. 12. The automatic dispensing cap of claim 1, further comprising a tube having a first end and a second end, said first end locatable within the container proximate a bottom thereof and said second end being connected to a port into said chamber. 13. The automatic dispensing cap of claim 1, further comprising a piston located at least partially within said retainer cap, said sealing lip and said protrusion extending from said piston. 14. The automatic dispensing cap of claim 13, wherein said piston is hollow and has an opening leading from an interior of the container into said pressure chamber. 15. The automatic dispensing cap of claim 1, further comprising a tube having a first end and a second end, said first end locatable within the container proximate a bottom thereof and said second end being connected to a port into said chamber. 16. An automatic dispensing cap for use with a container, said automatic dispensing cap comprising: a body connectable to the container, a retainer cap connected with said body and having a chamber therein, a sealing lip slidably resting against an interior surface of said retainer cap, a dispensing hole exiting said dispensing cap, a protrusion selectively sealing and unsealing said dispensing hole, a spring biased to hold said protrusion to seal said dispensing hole, a vent opening extending through said body into said chamber and a flapper valve located over said vent opening. 17. The automatic dispensing cap of claim 16, wherein said automatic dispensing cap has locked position and an unlocked position, wherein, when said automatic dispensing cap is in said locked position said protrusion is held in said dispensing opening. 18. The automatic dispensing cap of claim 17, wherein said automatic dispensing cap is rotatable between said locked position and said unlocked position.
