Benefits of technology

[0013] It is an object of the present invention to provide an inexpensive, reliable and substantially leak proof hingeable container cap assembly which does not rely on a separate gasket or o-ring to provide the seal or a separate latch arrangemen

Problems solved by technology

Conventional snap-lid type of caps inherently do not provide a positive seal to establish a long shelf life for liquids or edibles stored therein.
Such bottle caps as these are generally not provided with any type of sealing means such as gaskets.
Threaded lids generally include gaskets, but are not handy to use, especially for large mouth containers.
Such containers and lids are normally fairly rigid, but may be subject to some amount of flexure especially where the lid or cover is arranged to be peeled off of the container mouth.
Such sealing arrangements generally require considerable effort to force the lid onto the sealing bead during the closing procedure and perhaps greater effort to peal the lid away from the conta

Embodiment Construction

[0033] Referring more particularly to FIG. 1, there is shown a pictorial view of a container 10 having a neck portion 11 on which is commonly formed an external thread (not shown). It should be readily understood that container 10 is illustrative of various types and sizes of containers, such as bottles, jars, and the like, that hold liquids as well as dry food products.

[0034] A container cap assembly, generally designated at 12, is shown mounted on the container 10 and is formed from a suitable rigid or semirigid thermoplastic material of, for example, the polyolifin group, such as high density polyethylene, more preferably from a polypropylene that provides some flexibility and memory. Polypropylene is believed to be the least expensive of most commonly used plastics for molding many consumer products and thus advantageous from the cost standpoint. The container 10 is illustrated as a large mouth container, for example, having a standard diameter of 53 mm, 63 mm, 89 mm, 110 mm or...

Abstract

A container cap assembly comprises an annular cap body hinged to a lid. The cap body has a lower section with internal female threads for cooperation with matching male threads on a container and an annular upwardly extending flange. The lid has a downwardly extending flange. The flanges have interlocking sealing surfaces which extend outwardly at an acute angle to the vertical so that the lid flange will snap over the cap body flange in the closing mode and retain the lid in a closed and sealed position relative to the cap body until the lid is forced upwardly.

Description

RELATED APPLICATION [0001] This application is a continuation-in-part of application Ser. No. 10 / 652,744 filed Aug. 29, 2003 entitled Container Cap Assembly.FIELD OF THE INVENTION [0002] The present invention relates to a hinged cap assembly for capping containers and particularly to large mouth containers where a liquid tight seal is desired. DESCRIPTION OF THE PRIOR ART [0003] There are many known varieties and shapes of container caps including bottle-type caps that have been and are presently in use. The known caps differ in configuration and arrangement int hat some are formed as just single cap members having cooperative sizes to conform to the sizes of the containers or bottles. Some are defined as simple snap-on caps and others are provided with internal threads arranged to match the threaded arrangements of particular designed containers. [0004] Conventional snap-lid type of caps inherently do not provide a positive seal to establish a long shelf life for liquids or edibles...
