Claims
- 1. A molded plastic ectosealed toiletry dispenser comprising;a container, said container including a first set of threads thereon; a liquid toiletry located in said container; a ball applicator located on said container for dispensing the liquid toiletry; an annular peripheral shoulder extending around said container, said annular peripheral shoulder spaced from an end of said container; a resilient sealing ring located on said annular peripheral shoulder, said resilient sealing ring supported in an axial direction by said shoulder and in a radial direction by a container wall; a cap, said cap having a second set of threads for forming mating engagement with said first set of threads, said cap having a peripheral annular lip at an opened end thereon so that when said cap is threadingly engaged with said container the rotation of said cap about said container axially compress the resilient sealing ring between said annular lip and said annular peripheral shoulder to form a leak proof seal between an interior of the container and an exterior of the container to thereby prevent the toiletry located in said container from escaping therefrom in the event of air pressure outside the container falls below the air pressure inside the container.
- 2. The toiletry dispenser of claim 1 wherein the shoulder extends perpendicularly radially inward and the annular lip extends perpendicularly radially inward.
- 3. The toiletry dispenser of claim 1 wherein the shoulder forms an acute angle with the sidewall of the container to prevent the sealing ring from being forced radially off said shoulder when said cap is axially secured to said container.
- 4. The toiletry dispenser of claim 1 wherein the shoulder includes an annular recess for restraining said sealing ring from a radial outward displacement when the annular lip of the cover is squeezed against said sealing ring.
- 5. The toiletry dispenser of claim 1 wherein the annular lip on the end cap includes a sealing surface locate at an acute angle to an exterior wall of said container to prevent the sealing ring from being forced off said shoulder when said cap is axially secured to said container.
- 6. The toiletry dispenser of claim 1 wherein both the toiletry dispenser cap and the toiletry dispenser container are injection molded plastic.
- 7. The toiletry dispenser of claim 1 wherein the resilient seal comprises an elastomeric material of sufficient durometer so as to compress into a fluid tight seal when axially squeezed.
- 8. The toiletry dispenser of claim 1 wherein at least a portion of the resilient seal is visible around the exterior of the toiletry to provide a visual indication that the toiletry dispensers is in a sealed condition.
- 9. A toiletry dispenser comprising;a container includes a roll-on ball; a dispensable toiletry located in said container; an annular peripheral shoulder extending around said container, said annular peripheral shoulder extending radially inward to form a first sealing surface; a resilient sealing ring located on said seat, said resilient sealing ring supported in an axial direction by said first sealing surface; a cap, said cap forming mating engagement with said container so that when said cap is engaged with said container an annular lip at an opened end of said cap axially compress the resilient sealing ring between said annular lip and said annular peripheral shoulder to form a leak proof seal between an interior of the container and an exterior of the container to thereby prevent the toiletry located in said container from escaping therefrom in the event of air pressure outside the container falls below the air pressure inside the container, wherein the sealing ring is positioned at a circumferential terminus region of the cap and the dispensable toiletry comprises a liquid.
- 10. The toiletry dispenser of claim 9 wherein the resilient sealing ring comprises an elastomer.
- 11. The toiletry dispenser of claim 10 wherein the sealing ring includes a retaining lip to prevent over tightening of the cap and the container.
- 12. The toiletry dispenser of claim 10 wherein the sealing ring comprises an elastomer material.
- 13. The toiletry dispenser of claim 12 wherein the cap and the container comprises a polymer plastic.
- 14. The toiletry dispenser of claim 13 wherein the sealing ring is frictionally secured to the container to remain on the container as the cap is removed from the container.
- 15. The toiletry dispenser of claim 14 wherein the shoulder extends 360 degrees around the container.
- 16. The toiletry dispenser of claim 15 wherein the sealing ring has an outside diameter smaller than the diameter of the container but larger than the diameter of the threads.
- 17. The toiletry dispenser of claim 14 wherein the sealing ring forms a decorative band around the toiletry dispenser.
- 18. The toiletry dispenser of claim 17 wherein the sealing ring forms a cushion to limit the axial displacement of said cap with respect to said container.
