Williamson, Moutclair, N.J., assignor to American Aluminum Company, Mountainside, N.J., a corporation of New Jersey Filed Mar. 29, 1962, Ser. No. 183,600 1 Claim. (Cl. 22039) This invention relates in particular to aluminum bot tles having removable closure caps, but the invention may be embodied in closures for other containers such as drums and analogous vessels, particularly containers constructed of aluminum or other metal that is light in weight.
One object of the invention is to provide a novel, simple and inexpensive closure for a container that has a neck portion, so constructed that the interior surface of the neck portion shall be straight and smooth and devoid of obstructions such a screw threads, flanges and other projections, and the mouth of the container at the outlet end of the neck portion will be tightly sealed by coaction of a cap and a collar mounted in a new way on said neck.
Another object is to provide such a closure which shall include a novel and improved construction and combination of a neck portion on a container that has a sealing surface at its outer end, an adaptor or a collar, and a cap, said cap and adaptor coacting with said neck and each other in a novel and improved manner whereby connection of the cap to the adaptor and a tight sealing of the cap in contact with said sealing surface of the neck can be easily and quickly effected.
A further object of the invention is to provide such a closure the construction of which permits easy and rapid cleaning of the inner surfaces of the neck and the adaptor and cap.
Other objects, advantages and results of the invention will be brought out my the following description in conjunction with the accompanying drawings in which v FIGURE 1 is a side elevation of a metal bottle having a closure embodying the invention with the closure in closed position and with portions broken away and shown in section;
FIGURE 2 is a similar view showing the closure in open condition preliminary to applying the cap to the adaptor and neck and illustrating the adjustability of the adaptor or collar to facilitate connection of the cap thereto;
FIGURE 3 is a greatly enlarged fragmentary vertical sectional view through portions of the cap, neck and adaptor, more clearly illustrating the sealing relation of the parts;
FIGURE 4 is a top plan view of the bottle and closure as shown in FIGURE 1;- r
FIGURE 5 is a fragmentary composite side elevation and vertical section through the neck and the adaptor with the cap removed and the adaptor in its normal position when the closure is open;
FIGURE 6 is a top plan view of the parts shown in FIGURE 5 taken from the plane of the line 66 of FIG- URE 5; i j
FIGURE 7 is a horizontal sectional view on the plane of the line 77 of FIGURE 5; and
FIGURE 8 is a detached side elevation of the adaptor or. collar.
Specifically describing the illustrated embodiment of the invention, the reference character A designates a container in the form of an aluminum bottle drawn from and at the extremity or mouth of which is an outturned flange 3 disposed in a plane approximately normal to the axis of the neck and having a flat annular sealing surface 4.
In accordance with the invention to tightly close and seal the bottle, a cap B coacts with an adaptor C which is loosely mounted on the neck exteriorly thereof in a floating relation thereto and has limited movementlongitudinally of the neck; and the cap and adaptor or collar have coacting fastening elements such as screw threads 5 on the adaptor and mating screw threads 6 on the skirt of the cap which is shown as molded of plastic material integrally with the top 7 of the cap, for connecting the cap in sealed relation to the neck.
As shown, the adaptor or collar C is a thin-walled sleeve circular in cross-section and encircles the neck .and is formed of relatively thin aluminum withan intu-rned flange 8 at its outer end to abut the flange 3 of the neck. The adaptor also has an outturned flange 9 at its other innerend that normally abuts the shoulder or top wall It? of the bottle as best shown in FIGURE 5. The collar and its inturned flange 8 are shown of an internal diameter greater than the external diameter of the neck so that the collar may be tilted or cocked on the neck as shown in FIGURE 2 by gripping the peripheral edge of the flange 9, to facilitate engagement of the threads 5 of the adaptor-with the threads 6 of the cap, and the length of the adaptor is such that it may move longitudinally between the flange 3 and the shoulder 10 of the bottle.
It will be understood by those skilled in the art that the collar will he slipped onto the neck before the flange 3v is formed, the portion of the neck of which the flange is formed being as shown by broken lines in FIGURE 5 before the formation of the flange. After the collar or adaptor has been applied to the neck, the flange is formed and thereafter prevents disengagement of the adaptor from the neck.
In operation of the closure, assuming the cap to be removed, the cap is gripped in one hand and the edge of the flange 9 of the adaptor is gripped between the thumb and index finger of the other hand, after which the cap is moved into engagement with the end of the adaptor and the adaptor is tilted or wiggled until proper mating of the threads of the adaptor and the cap is effected. Thereupon the cap is screwed onto the adaptor and the adaptor is pulled into a position with its flange 8 in abutting contact with the neck flange 3 and simultaneously the capis drawn into tight conact with the sealing surface 4 of the neck as shown in FIGURES 1 and 3. Desirably, a packing disc 11 of suitable material is interposed between the top of the cap and the flange 3 to provide a more effective seal.-
In some containers it may be desirable to utilize a cork, and in such casesthe neck may be formed with a frusto conical inner surface having its larger end at the mouth or outlet end of the neck sov that a cork can be tightly fitted in the neck and the cap will hold the cork against displacement under great pressure differential between the interior and exterior of the container.
Also, the flange 9 of the adaptor may be perforated as indicated at 12 to permit the use of a tamper-proof seal, and the cap B would be perforated in a suitable manner or could be formed of metal with a perimetral flange also perforated, so that a tie wire could be threaded through the perforations of the adaptor and the cap in a manner similar to the known types of wire seals.
It will thus be seen that the invention provides a simple Lterior threads, a metal adaptor which permits the use of simple and inexpensive rolledthreads, and an association of the adaptor and the cap with the neck of the container such that the cap can be easily and quickly 'manipulated into container-closing or sealing condition a and the adaptor, neck and cap can be easily maintained in clean and sanitary condition.
The construction also provides for automatic adjustment of the cap ,to the sealing surface as the cap is screwed onto the adaptor, thereby eliminating any necessity for precision in the formation of the several parts of the closure and yet insuring a tight seal of the opening through the neck.
I claim: 7
A'closure construction for a container comprising a neck having an opening therethrough formed with a straight and smooth interior surface and a circumferential outturned flange at the extremity of said neck, one side of said flange providing an outer annular sealing surface disposed in a plane approximately normal to the axis of said opening, a cap for closing said opening through the neck, an adaptor sleeve circular, and rigid in cross-sec- .tion and having an internal diameter greater than the external diameter of said neck, said adaptor loosely encircling said neck exteriorly thereof and being movable longitudinally of the neck providing for abutment of one end of said adaptor with said flange at the side of the flange opposite said sealing surface upon movement of the adaptor in one direction, there being means for limiting movement of said adaptor in the other direction, said cap and said adaptor having complemental fastening means for connecting the cap to the adaptor and for drawing the adaptor into contact with said flange and the cap into contact with said sealing surface upon relative rotation of the cap and the adaptor, said adaptor being a thin-walled sleeve formed of one piece of metal and having rolled screw threads adjacent its outer end, said cap comprising a top portion and a skirt having threads complemental to said rolled threads of the adaptor, said adaptor also having an inturned continuous circular flange at its outer end to abut said flange on the neck and also having an outturned flange at its opposite end for manipulating the adaptor on the neck, and said adaptor being freely rotatable and tiltable on said neck.
