Watertight closure system
View Patent ↗The present invention provides a resealable closure system that may be incorporated into a container for storing and dispensing moisture sensitive product, such as a dry wiping substrate and more preferably a dry wipe useful for facial cleansing or the application of make-up. The closure system is not only resealable, but is also substantially watertight as a result of the lid having a sealing flange and an overhang.
1. A closure system comprising a base having an annular sidewall and a central opening; a lid configured to substantially cover the central opening of the base, the lid having a front, a rear edge having a length and a pair of opposed side edges having a length; a pair of flanges having a height extending substantially vertically from and at least partially along the length of the side edges and at least partially defining a peripheral outer edge of the closure system; and a hinge that operatively connects the lid to the base in a movable arrangement, wherein the flanges do not extend along the front edge of the lid and the front edge of the lid extends beyond the vertical plane of the annular sidewall and the flanges extend beyond the horizontal plane of the annular sidewall when in a closed position.
2. The closure system of claim 1 , wherein the hinge is a living hinge.
3. The closure system claim of 2 , wherein the flanges extend along the entire length of both side edges and along a portion of the rear edge.
4. The closure system of claim 3 , wherein the flanges terminate immediately adjacent to the living hinge.
5. The closure system of claim 1 , wherein each flange has an inner and an outer surface, the outer surface biased radially outward and away from one another.
6. The closure system of claim 1 , wherein the height of the sealing flange is substantially constant and the flange is spaced away from the base when the lid is in a closed position.
7. The closure system of claim 1 , wherein the lid further comprises a depressed central portion.
8. The closure system of claim 1 , wherein the lid further comprises a catch mechanism proximate the front portion of the lid, the catch mechanism engaging the base to hold the lid in a closed position.
9. The closure system of claim 1 , wherein the lid further comprises a latch with an elongated rib extending horizontally therefrom and the body further comprises a second elongated rib extending horizontally therefrom whereby the first and second ribs removably engage one another in an interface fit to maintain the lid in a closed position.
10. A container comprising a cup-shaped container body having a generally annular sidewall defining an open end; a lid having a main body having a front edge, a back edge having a length and a pair of opposed side edges having a length, the lid sized large enough to close the open end of the container body, a pair of flanges extending from a bottom surface of the main body and beyond the horizontal plane of the annular sidewall in a closed position to at least partially define the outer peripheral edge of the lid and wherein the flanges extend along the entire length of both side edges and along a portion of the back edge, but do not extend along the front edge of the lid, the lid further comprising an overhanging front edge that extends beyond the vertical plane of the annular sidewall in a closed position; and a living hinge coupling the container lid and container body, the container lid pivoting through the living hinge between an open position and the closed position.
11. The container of claim 10 , wherein the flanges terminate immediately adjacent to the living hinge.
12. The container of claim 10 , wherein each flange has an inner and an outer surface, the outer surface biased radially outward and away from the inner surface.
13. A watertight dispenser comprising a container body having a bottom and a generally annular sidewall defining an open end and a closure system sized to cover the open end of the container, the closure system comprising a base, a lid and a hinge, wherein the lid comprises a rear edge having a length, a pair of opposed side edges having a length, a pair of flanges having a height that extend downward from the horizontal plane of the lid and beyond the horizontal plane of the base and at least partially defining a peripheral outer edge of the lid and wherein the flanges extend along the entire length of both side edges and along a portion of the rear edge, but do not extend along the front edge of the lid and an overhanging front edge that extends beyond the vertical plane of the front edge of the base when the lid is in a closed position.
14. The container of claim 13 , wherein the flanges terminate immediately adjacent to the hinge.
15. The closure system of claim 13 , wherein the height of the flange is substantially constant and is spaced away from the base when the lid is in a closed position.
