Shaped elastomeric container with integrated leak resistant seal

Abstract

A container made of an elastomer such as silicone with an integrated leak resistant seal. The seal incorporates press-fit elements with sizes and shapes sufficient to provide a strong seal that resists leakage of liquids from inside the container. The seal is integrated into the container and requires no external clips or clasps. Additional features are provided to facilitate opening such as extended flaps for pulling the sides open, and asymmetric cavities for press-fit elements to reduce the initial opening force. The container itself may be of asymmetrical shape, such as trapezoidal, to provide a wide opening along with a strong seal.

Description

Such a gap is shown at gap 819 having horizontal width G1 between first boundary of contact having horizontal width B1, starting at contact point 820 when traversing the seal from left to right up to contact point 821 (where the gap begins) and second boundary of contact having horizontal width B2, starting at contact point 822 (where the gap ends) when traversing the seal from left to right up to contact point 823. Hence a longer and more tortuous path increases the leak resistance of the seal. Different embodiments may employ various shapes for such a winding path. FIG. 11 illustrates the boundary path for the embodiment shown in FIG. 8. The relative length of the different segments of the boundary are shown in FIG. 11; for example the leftmost horizontal segment has length 1102 of 1.0. (The lengths shown are only relative to one another; they are not expressed in any specific units.) In the embodiment shown, the total length 1103 of the winding boundary path is 17.5. The horizontal distance 1101 between the start and end of the path is 7.0. Thus the path length is approximately 2.5 times the horizontal distance. This ratio of path length to horizontal distance is a quantification of the extent to which the boundary path winds and changes directions, which contributes to the sealing force and the leak resistance. Some embodiments of the invention, such as the one shown in FIG. 11, have a boundary path length of at least twice the horizontal distance between the start and end of the path.

Some embodiments of the invention utilize multiple techniques to enhance the leak resistance of the seal. For example, the embodiment shown in FIG. 8 provides a winding boundary path of length more than twice the horizontal distance, as well as three or more normal vectors in each of the four directions up, down, backward, and forward. In some embodiments such techniques may be combined with a high average material thickness or other dimensional or material variations for the press-fit elements to further increase the leak resistance.

In one or more embodiments of the invention, the press-fit elements of the seal may extend to portions of the left edge or the right edge, or both, of the top and bottom enclosures. FIG. 12 illustrates an embodiment in which the press-fit elements are located along the front edges and also along the front portions of the left and right edges. FIG. 12 shows an exploded view of the top enclosure 101 and bottom enclosure 102. In this embodiment top press-fit element 231 has portion 1201 that is proximal to left side 112, and portion 1202 that is proximal to right side 113. Similarly bottom press-fit element 232 has portion 1203 that is proximal to left side 212 and portion 1204 that is proximal to right side 213. In the embodiment shown, the press-fit elements curve around the corners between the front edge and the left and right edges. In other embodiments the press-fit elements may form right angles at the corners, or may form any curved or polygonal shape to extend from the front edge to the left and right edges. Embodiments may employ curved shapes for the corners that may be circular, oval, elliptical, or any other shape. Embodiments may employ polygon shapes for the corners that may be rectangular, or they may use multiple segments with any angles between the segments. In some embodiments the press-fit elements may extend to only one of the left or right edges. A potential advantage of embodiments in which the press-fit elements extend to the left and right edges is that the opening of the container may be wider, simplifying insertion or removal of objects.

In one or more embodiments of the invention, the container may include a top flap or a bottom flap, or both, proximal to the opening. These flaps may be used for example for grasping the edges of the container when opening or closing the container. FIG. 12 illustrates an embodiment of the invention with a top flap 1210 and a bottom flap 1211. In some embodiments the shapes and sizes of the top flap and the bottom flap, if both are present, may be different. This is illustrated in FIG. 12 where top flap 1210 forms an arc extending from approximately the middle third of the top front edge, while bottom flap 1211 extends along the entire bottom front edge. FIG. 13 shows a close up view of the front of the embodiment illustrated in FIG. 12, shown in the closed position. As illustrated in FIG. 13, in this embodiment the bottom flap 1211 extends further forward than top flap 1210. Embodiments that employ flaps of different sizes may facilitate opening by making it easier for a user to grasp one of the flaps to begin opening. Different embodiments may use different sizes and shapes of flaps, including symmetric designs with similar shapes for top and bottom flaps, and asymmetric designs as illustrated in FIG. 13.

FIG. 14 illustrates an embodiment of the invention with a vertical gap between the top flap and the bottom flap, to facilitate grasping the flaps for opening. In this embodiment top flap 1210 has a curved form that is vertically offset from bottom flap 1211 by distance 1401. This shape may make it easier for a user to insert his or her fingers into the space between the flaps. In this embodiment bottom flap 1211 has a series of ridges running parallel to the front edge of the container, to aid in grasping the flap. In the embodiment shown in FIG. 14, the press-fit elements are located along the front edges and also along the front portions of the left and right edges. Top press-fit element 231 has portion 1201 that is proximal to left side 112, and portion 1202 that is proximal to right side 113. Similarly the bottom press-fit element extends to the left edge and the right edge. In this embodiment, the press-fit elements curve around the corners between the front edge and the left and right edges.

While the ideas herein disclosed have been described by means of specific embodiments and applications thereof, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope of the invention set forth in the claims.
