• the exemplary seal is an easily manufacturable venting disc which can be formed from a non-venting material or membrane that is tearable or puncturable, or configured to be removable via a tab or other exertion of force.
• the exemplary venting disc may be manufactured from any material that provides a robust "seal" while still allowing the customer to remove the seal, as needed.
• One of many possible non- limiting examples include materials selected from the group comprising: foil, plastic, fabric, metal, nylon, layered membranes, and so forth.
• the method for attaching or securing the exemplary disc to the container mouth may be facilitated by tightening a cap or by adhering the disc to the container mouth lips using an adhesive or pressure, etc.
• the exemplary venting disc may be of a one-time - use, while in other embodiments, the exemplary venting disc may be multiply used.
• the "longevity" of use intended for the exemplary venting disc can dictate the exemplary venting disc manufacturing material.
• Fig. 1 is a top view of an exemplary venting disc 10 having a shape suitable for sealing a container (not shown) with an outer portion 1 1 and inner portion 13 bridged by a non-planar portion 15 distal to inner portion 13.
• the outer portion 1 1 is shown punctuated with a gap 17 having a predetermined size that is located adjacent to an exterior edge of the non-planar portion 15.
• the gap 17 provides an opening for gases to escape from the interior of the container to the exterior, while also preventing solid material or large sized materials to escape to the exterior.
• the non-planar portion 15 can operate to center the exemplary venting disc 10 about the container mouth and also to constrain the exemplary venting disc 10 from slipping off the container mouth.
• the outer portion 1 1 is of a predetermined size to constrain the gap 17 to provide a restricted opening between the lip of the container (shown in Fig. 5) and the exterior edge of the non-planar portion 15.
• Fig. 2 is a bottom prospective view of the exemplary venting disc 10 of Fig. 1. From this vantage point, non-planar portion 15 is shown as a "V"- like depression in the material of the exemplary venting disc 10 that circles the entire disc 10. The outer wall of the non-planar portion 15 can butt against the inner rim of a container lip and operates to prevent the exemplary venting disc 10 from slipping off the container mouth. [0025] It should be appreciated that the terms planar and non-planar are used herein to differentiate the various sections of the disc 10.
• the section 1 1 of the disc 10 that rests on the container top's lip is differentiated from the section 15 of the disc 10 that abuts the inner edge of the container top's lip, by labeling the former as planar while the latter as non-planar.
• the non-planar portion can be referred to as an intermediate portion, without loss of generality. Therefore, the terms planar/non-planar are understood to encompass other contours for the surfaces of the disc 10. For example, it is contemplated that certain planar portions may be curved, having a concave, convex, or dome shape.
• the outer rim 1 1 of the disc 10 that rests on the container's lip may be curved in one direction while the inner section 13 of the disc 10 may be flat, depressed, raised, or curved. Therefore, while the various embodiments described herein utilize the terms planar and non-planar, it should be understood that these terms can be broadly applied to refer to contours that are not planar.
• disc is also a generic term as used herein, being referable also to non-circular shapes such as squares, ovals, rectangles, and other shapes that may be used for container openings. Therefore, while the exemplary embodiments herein are illustrated as having a circular or "disc-like" shape, other shapes are understood to be within the purview of this disclosure.
• Fig. 3 is a top view of another exemplary venting disc 20 having a contiguous portion 21 that spans the exemplary venting disc 20.
• Non-planar portions 25 are disposed in discrete segments about contiguous portion 21 at a predetermined distance from the edge of the exemplary venting disc 20 to operate in a similar fashion to the non-planar portion 15 shown in Figs. 1 and 2.
• Multiple gaps 27 of predetermined sizes are placed at the periphery of the exemplary venting disc 20.
• the arrangement and number of the gaps 27 with respect to the non-planar portions 25 can be modified, as according to design preference.
• the gaps 27 may be co-radial with the non-planar portions 25, or less or more gaps 27 may be utilized as compared to the non- planar portions 25.
• Fig. 4 is a top view of another exemplary venting disc 30 having non-planar portions 35 formed as dimples or discontinuous projections/depressions into the contiguous portion 31.
• Multiple gaps 37 of predetermined sizes are placed at the periphery of the exemplary venting disc 30.
• the arrangement and number of the gaps 37 with respect to the non-planar portions 35 can be modified, as according to design preference.
• Figs. 3 and 4 illustrate the possibility of modifying the non-planar portions to be of different shape and arrangement about the respective disc. Therefore, while only a "V" or dimple shape is shown in the above Figs., other shapes known to one of ordinary skill in the art are contemplated herein and are understood to be within the purview of this disclosure. Similarly, the "symmetry" of the non-planar portions and the gaps about the exemplary discs may also be altered to allow for non- symmetric placement of the non-planar portions/gaps. As evident in Fig. 3 and Fig. 4, the gap shape may be variable. Therefore, the gap may have any desired geometric shape, such as for example, square, curved, oval, ornate, etc., without departing from the spirit and scope of this disclosure.
• FIG. 5 is an exaggerated perspective view of another exemplary venting disc 40 on a container opening.
• the venting disc 40 has outer portion 41 bridged by non- planar portion 45 to inner portion 43.
• Gaps 47 are shown distributed about the outer portion 41 showing container lip 49 supporting the outer portion 41.
• the gap 47 is bounded by fore and rear sides 47a and 47b and the inner edge of the container lip 49 to result in an opening 47c that is smaller than the actual size of the gap 47. Accordingly, with an understanding of the container lip 49 thickness/size, the gap 47 can be determined to generate an actual opening 47c sized to allow gases to vent from the interior of the container 44 while preventing the exit of the material (not shown) from inside the container 44.
• Fig. 5 is an exaggerated view in that the non-planar portion 45 is shown to be significantly displaced from the container lip 49, to allow the opening 47c to be easily viewable in this illustration.
• the non-planar portion 45 will be, in many instances, closer to the container lip 49, especially if the individual material inside the container is smaller than the gap 47.
• the material type and size will help determine the appropriate size of the opening 47c.
• Fig. 6 is an exploded perspective view of another exemplary venting disc 50 on a container or bottle top 64.
• Bottle top 64 can be a typical bottle in that inner section 66 is rimmed with lip 67 and surfaced with a spiral thread 69 for tightening on cap 62.
• the exemplary venting disc 50 is configured with a ringed non-planar portion 55 that is circumvented with gaps 57.
• the exemplary venting disc 50 may be secured to the bottle top 64 by use of the cap 62 or by use of an adhesion mechanism or other securing mechanism, as according to design preference.
• Cross section of cut line A-A in a non- exploded view is described below.
• Fig. 7 is a view of the A-A cross-section shown in Fig. 6, where cap 62 is secured to the bottle 64 via bottle thread(s) 69 and cap thread 79.
• gases 75 from the interior of the bottle can escape through the disc 50 via the opening formed between the inner edge of the bottle 90, the edge of the non-planar portion 55 proximal to the inner edge of the bottle, and the gap 57.
• the gases 75 channel out (and also in) through the open spiral spaces formed between the cap thread 79 and the bottle thread 69.
• the non-planar portion 55 when properly sized with respect to the bottle top, can be configured to have a slight amount of lateral play within the bottle top. Accordingly, at least one gap 57 will be positioned to allow the necessary opening for the gases 75 to escape.
• Fig. 8 is a top view of another exemplary venting disc 60. Outer portion 61 is bridged by non-planar portion 65 to inner planar portion 63. Gaps 67 are disposed about the disc 60, but with dimensions that protrude into inner planar portion 63.
• the material being stored in the container is a paste or non-liquid material that will not, by virtue of its viscosity or makeup, pass through the gaps 67. Analogously, the material may be of a size that is larger than the gap 67 size.
• Fig. 9 is a top view of another exemplary venting disc 70 with a tab 72.
• This embodiment illustrates the ability to affix a tab 72 at one end of the disc 70 for easy disc removal.
• Non-planar portion 75 circumvents the entire disc 70 to bridge gaps 77 with inner portion 73.
• a design 74 can be embossed, printed, etc. on the interior 73 of the disc 70, if so desired.
• Fig. 10 is a top view of another exemplary venting disc 80 with a tab 82.
• more gaps 87 are presented as well as being more curved in shape than that of the embodiment shown in Fig. 9. Additionally, the non-planar portions 85 are not continuous around the disc 80.
• Inner portion 83 is shown with an optional design 84.
• Fig. 1 1 is a top view of another exemplary venting disc 90 with a design 94. It is noted that gaps 97 can be coordinated in position around outer portion 91 to "flow" with various elements of the design 94. As shown in the above embodiments, gaps 97 are situated in the outer portion 91 being bridged by non-planar portion 95 to inner portion 93.
• Fig. 12 is a top view of another exemplary venting disc 100 with a design 104 and tab 102.
• the design 104 is an expanded version of the design 94 shown in Fig. 1 1.
