Container venting disc
A container venting disc is punctuated with gaps around the periphery to allow gases from the interior of the container to vent. An intermediate ridge or layer that abuts or is proximal to the interior edge of the container lip is implemented to prevent the disc from significantly moving laterally and to also center the venting disc within the container mouth. The gap(s) forms a channel in the disc to allow gases to escape between the edge of the container mouth and the container cap. The simplicity of design allows for easy manufacture and simple placement in a container, such as for a jar or bottle.

This subject matter relates to a sealing membrane for an enclosure capable of venting gases. More particularly, it relates to a venting disc for a container top.
BACKGROUNDThe need to store material inside an enclosure such as a container is measured against the need for the consumer to be able to breach the enclosure to access the material. A typical breaching mechanism is a removable cap that is tightened or snapped over the container mouth. However, due to tampering or other concerns, an airtight liner or seal is usually secured over the container mouth. In some instances, the airtight liner or seal prevents the venting of gases that are built up from the stored material and the seal will eventually burst or the container will break. Several approaches, such as shown in U.S. Pat. Nos. 5,579,936 and 5,730,306 to Costa et al., show designs for allowing venting, but these designs are particularly suited for liquid materials and are somewhat complicated to manufacture.
What is desired is a sealing mechanism that is less complicated and also suited for non-liquid materials, such as pills, pastes or large granules, etc. To that end, the following description details a container venting disc that addresses these and other deficiencies in the industry.
SUMMARYThe following presents a simplified summary in order to provide a basic understanding of some aspects of the claimed subject matter. This summary is not an extensive overview, and is not intended to identify key/critical elements or to delineate the scope of the claimed subject matter. Its purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.
The foregoing needs are met, to a great extent, by the present disclosure wherein a venting removable cover for a container opening is provided, the container opening being sealable with a cap, comprising: a non-venting outer portion having a predetermined dimension and shape to rest on a lip of the container opening; a non-venting inner portion that spans an interior face of the container opening; at least one non-venting intermediate portion bridging the outer portion and the inner portion, shaped to protrude into an interior of the container and being disposed at a position proximal to an interior edge of the lip of the container to prevent slippage of the removable cover from the container opening; and at least one venting gap through the outer portion, spanning from an outer edge of the outer portion to an outer perimeter formed by the at least one intermediate portion.
In another aspect of the present disclosure, a method for venting gases from a container opening covered by a removable venting disc is provided, the container opening being sealable with a cap, comprising: forming a non-venting outer portion of the removable venting disc having a predetermined dimension and shape to rest on a lip of the container opening; forming a non-venting inner portion of the removable venting disc that spans an interior face of the container opening; forming at least one non-venting intermediate portion of the removable venting disc bridging the outer portion and the inner portion, shaped to protrude into an interior of the container to prevent slippage of the removable cover from the container opening and disposed at a position proximal to an interior edge of the lip of the container; and forming at least one venting gap in the outer portion of the removable venting disc, spanning from an outer edge of the outer portion to an outer perimeter formed by the at least one intermediate portion.
In another aspect of the present disclosure, a venting removable cover for a container opening is provided, the container opening being sealable with a cap, comprising: non-venting means for resting on a lip of the container opening, having a predetermined dimension and shape; non-venting means for spanning an interior face of the container opening; non-venting means for bridging the means for resting on the lip and the means for spanning, shaped to protrude into an interior of the container to prevent slippage of the removable cover from the container opening, and disposed at a position proximal to an interior edge of the lip of the container; and means for venting gases through the means for resting, spanning from an outer edge of the means for resting to an outer perimeter formed by the means for bridging.
The features and nature of the present disclosure will become more apparent from the detailed description set forth below when taken in conjunction with the drawings in which reference characters identify corresponding items and processes throughout.
The disclosed methods and systems below may be described generally, as well as in terms of specific examples and/or specific embodiments. For instances where references are made to detailed examples and/or embodiments, it should be appreciated that any of the underlying principals described are not to be limited to a single embodiment, but may be expanded for use with any of the other methods and systems described herein as will be understood by one of ordinary skill in the art unless otherwise stated specifically.
The ability to “seal” a container top, but in a manner that is breachable by the customer, requires an exemplary venting disc to be removable. In various embodiments described herein, 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. Thus, 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. In some embodiments, 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. In some embodiments, the exemplary venting disc may be of a one-time-use, while in other embodiments, the exemplary venting disc may be multiply used. Accordingly, the “longevity” of use intended for the exemplary venting disc can dictate the exemplary venting disc manufacturing material.
It should be appreciated that the terms planar and non-planar are used herein to differentiate the various sections of the disc 10. For example, the section 11 of the disc 10 that rests on the container top's lip (not shown) 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. In some contexts, 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. Further, the outer rim 11 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.
Similarly, it should be appreciated that the term 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.
It should be noted that
As should be apparent from the above descriptions, various modifications to the arrangement/shape/etc. can be made to the exemplary embodiments without departing from the spirit and scope of this disclosure. For example, in
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present disclosure. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the disclosure. Thus, the present disclosure is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
