Problems solved by technology

However, once the membrane has been removed and the overcap replaced, the overcap may not create a tight fit with only the container surface because of the missing membrane.
An insufficient fit may allow oxygen, moisture, or contaminants to enter the container or may cause the overcap to come off unintentionally.

Embodiment Construction

[0013] The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.

[0014] With reference to FIGS. 1-3, a sealable storage device in accordance with one embodiment of the invention is illustrated. The storage device 10 includes an overcap 12, a container 14, and a membrane 16. The container 14 is structured to store products within the container and to provide access to the stored products through an opening 18. A variety of products can be stored in the storage device 10; however, the storage device is preferably used to store perishable products because the membrane 16 provides...

Abstract

There is provided a double rib overcap for a container with a removable membrane. The skirt of the overcap includes a first inwardly projecting rib and a second inwardly projecting rib that are axially separated and includes inside surfaces of the skirt that are axially above each rib. The container has an opening that is encircled by a rim and the membrane covers the opening such that the membrane extends radially onto an outer surface of the rim. A first inside surface above the first rib of the overcap is dimensionally sized to create an interference-fit with the membrane and the rim when the overcap is connected to the container. Likewise, a second inside surface above the second rib of the overcap is dimensionally sized to create an interference-fit with the rim of the container when the overcap is connected to the container after the membrane has been removed.

Description

FIELD OF THE INVENTION [0001] The present invention relates generally to containers with overcaps. More particularly the invention relates to overcaps for containers with a removable membrane. The overcap has a skirt configured to engage a rim of the container with an interference-fit to seal the container. BACKGROUND OF THE INVENTION [0002] Containers that store perishable goods, such as food products, often include a sealed membrane to minimize the transfer of oxygen, moisture, or contaminants into the container. The membrane is removed by the customer when the container is first opened, and the membrane is discarded. An overcap is provided for re-closing the container after the initial opening. The overcap engages a rim (e.g., a rolled bead or a flange) on the top of the container in such a way that a snap-fit or interference-fit connection exists to retain the overcap in place on the container. [0003] When the membrane is located directly below the overcap, both overcap and memb...
