Application filed May 16, 1927. Serial No. 191,663.

The resent invention relates to the sealing art an more particularly to a sealed package and the parts thereof.

Heretofore in the sealing art various types of closure caps have been used to seal food products and the like. The caps which form the most secure hermetic seals generally adhere so effectively to the containersthat they are mutilated in their removal and are not 1 suitable for resealing. Hence the consumer permits the contents of the package to remain exposed to the atmosphere and impurities While it is being used. Naturally this is undesirable and many packers use the much less effective and less eflicient screw cap solely for the reason that it may be re-sealed indefinite 1y. Other packers have applied covers over the containers beneath the usual closure caps. With such covers as well as with screw and other re-seal caps; the interior and some timesthe exterior portionsbecome contaminated with the contents of the container and are accordingly sticky and unsightly.

The resent invention overcomes these 26 difficulties by providing a separate cover cap adapted to be nested over the usual closure on a container and to be removed and used as a cover for the container. The cover cap being mounted exteriorly of the container does not become contaminated with the contents thereof. Further its being nested over the usual closure cap gives the package the appearance of having .a deep skirt cap which is more desirable in the trade. This .is particularly beneficial with caps having narrow skirts.

An ob'ect of the invention is'to increase the dept of narrow flange caps without lowering the position of the seal on the containers and without increasing the head space of the containers.

Another object of the invention is to provide a cover cap adapted to be frictionally attached to the upper part of a closure cap to improve the appearance thereof and at the same time to serve as a'cover for the con tainer when the closure cap is removed.

Another object of the invention is to provide a cover cap having a resilient skirt adapted to size itself to the upper part of the closure cap and also to the outer side wall of a container.

Another object of the invention is to provide an effective covercap which may be readily attached to the present form of packages without detracting from the'appearance thereof to serve as a cover for the container after the closure cap is removed.

Other and further objects of the invention will be obvious upon an understanding of the illustrated embodiment about to be described and various advantages not referred to herein will occur to one skilled in the art upon employment of the invention in practice A preferred embodiment of the invention Fig. 5 is a sectional view of another form of cover cap; and v Fig. 6 is a perspective view of the elements in unassembled position.

Referring to the drawings there is shown a container 1 which may, for convenience, have an annular cylindrical sea-ling zone 2 adjacent its upper end. A closure cap 4 having a head 5 in the skirt thereof, is mounted upon the container with the bead deformed to press a gasket therein against the side wall of the container to effect a. hermetic seal. Theupper part of the head 5 for-ins with the skirt of the cap a shelf 6 which facilitates the application ofa cover cap 7 7 While various forms 0 cover caps may be used, there is shown in Fig. 5 one form having a cover portion 8 and a depending skirt 9 terminating in a wire edge 10 at the bottom thereof. The skirt of the cap is preferably flared slightly to facilitate its application to the upper part of the closure cap and to facilitate also its application to the container after the closure ca is removed, since the external dimensions 0 the closure cap and container differ slightly.

The form of cover cap shown in Figs. 2 and 3 is corrugated substantially the entire length of the skirt and does not have a wire edge at the bottom thereof. The corrugations 11 permit the skirt to expand readily to a limited extent. This facilitates the application of the cap both to the closure cap and to the container since it will size itself readily to these.

Preferably the covers are sufficiently small to nest over the upper portion of the closure cap and extend substantially down to the shelf 6, leaving a sufiicient space to permit the application of a tool or of a coin to pry the cover from the closure cap. Since the closure cap must be telescoped over the mouth of the container, it must be slightly larger than the container. The cover cap being nested over the closure cap is necessarily substantially larger than the external dimension of the container. By providing the readily yieldable skirt and sizing it so that the cover goes only partially down on the closure cap, its removal is facilitated and its size is more nearly that of the container. In this manner the cover may be properly sized to both the closure cap and the container.

The packages are sold with the three elements of the package in assembled relation as shown in Fig. 1. The consumer pries off the cover cap and thereafter removes the closure cap and replaces it by the cover which rotects the contents of the container against impurities while the food is being consumed. The height of the skirt of the cover cap adds to the apparent depth of the closure cap and gives the appearance of a deep skirt cap which is more attractive than the narrow skirts heretofore used.

It will be seen that there has been provided a cover cap inexpensive in construction and readily manufactured from commercial materials and that the cover. may be attached to packages now on the market without detracting from the appearance thereof.

It is readily sizable to both the closure cap and container without danger of accidental removal during shipment or in use.

As various changes may be made in the above embodiment without departing from the spirit of the invention, it is to be understood that all matter herein is to be interpreted as illustrative and not in a limiting sense.

Having thus described my-invention, I claim:

1. A sealed packages comprising acontainer, a closure cap having a head in the skirt thereof forming an annular flange, a gasket in the bead sealed to the outer side wall of said container and a cover cap frictionally attached to said closure ca above said head and adapted to increase the eight thereof.

2. A sealed package comprising a container, a closure cap hermetically sealed to the outer side wall of said container, the upper portion of said closure cap being tapered upwardly, and a cover cap adapted to rest on and be frictionally secured to the tapered part of said closure cap and to frictionally engage the side walls of the container thereby to provide a cover for the container after the closure cap is removed.

3. As an article of manufacture, a closure cap having the upper portion thereof tapered or of diminishing diameter, and a cover cap attached to the tapered part of the closure cap to improve the appearance thereof and to furnish a cover for a container after the closure cap is removed.

4. As an article of manufacture, a closure cap and a cover cap attached-thereto to improve theappearance thereof and to furnish a cover for a container after the closure cap is removed, said cover cap having a readily expansible skirt to fitabove the upper part of the closure cap and also about the side wall of the container.

5. As an article of manufacture, a closure cap having a relatively narrow skirt, a cover cap telescoped thereover and secured to the closure cap to give the elfect of a deep skirt, said cover being corrugated to expand or contact to proper size to fit upon the container when the closure cap is removed.
