UNITED STATES PATENT OFFICE.
GUSTAV F. ANDERSON, OF' BROOKLYN, NEW YORK, ASSIGNORv T0 PARAGON CAN CAP COMPANY, INC., 0F PATERSON, NEW JERSEY, A CORPRATION 0F NEW YORK.
Application filed May 28, 1923.
To all whom t may concer/lt.'
Be it known that I, GUs'rAv F. ANDERSON, a subject of the King of Sweden, and a resident of the borough of Brooklyn, in the county of Kings, city and State of New York, have invented certain new and useful Improved Receptacle Closures, of which the following is a specification.
This invention relates to closures for receptacles, such as bottles, having a depending flange or skirt to engage about the receptacle neck and secured'to the receptacle by bending or crimping the edge portion of the flange below a shoulder on the receptacle. To release the closure from vthe receptacle the closure skirt is arranged with an intermediate annular scoring to provide a weakened portion or line on which to disjoin or tear that portion from the closure skirt which engages the receptacle shoulder and retains it to the receptacle, said securing means also servingas a guard to prevent the surreptitious removal of the closure and tampering with or substituting the contents in the receptacle, and then replacing the closure. This type of closure when once removed from the receptacle while it may be ,utilized as a dust cap for the receptacle it cannot be retained with a suiicient degree of force to seal the opening ofthe receptacle with the result that the contents remaining in the receptacle deteriorate and become spoiled. A
It is the object of the present invention to provide a receptacle closure of this character in which after the rip or tearing strip of the closure has been torn or stripped from the closure to release it from 'the receptacle the closure skirt will be provided with pord tions adapted to yieldingly engage the shoulder of the receptacle, and the closure may be removed from and replaced upon the receptacle by a slight pull or push and when applied to the receptacle in such manner make a substantially air tight seal with the mouth of the receptacle, whereby a portion of the contents of the receptacle may be used and the remaining portion sealed within the receptacle without the liability of the remaining contents becoming spoiled or deteriorating due to it being open to the atmosphere.
In the drawing accompanying and forming a part of the specification, Figure l is a side elevation of the neck portion of a receptacle with my improved closure applied serial No. 641,839.
thereto, a portion of the closure being in section to show the arrangement thereof and the manner of securing the closure to the receptacle.
Figure 2 is a cross sectional view taken on the line 2 2 of Figure l looking in the direction of the arrow.
Figure 8 is a perspective view of my improved elosure looking at the lower end thereof; and A Figure 4 is a View similar to Figure i but with the tearing strip torn or disjoined from the closure and showing the manner of releasably retaining the closure on the receptacle after said strip is removed.
Similar characters of reference designate like parts throughout the different views of the drawing.
The embodiment of the invention shown in the drawing comprises a disk or top to engage at the opening of a receptacle R and having an annular depressed portion 6 to engag'e the edge of the mouth of the receptacle, with an interposed sealing material 7, such as a cork disk on a similar material, and the disk 5 arranged with a depending fiange or skirt 8 to engage about the neck of the receptacle. While the top and flange may be of integral structure stamped and drawn from a single piece of relatively ductile sheet metal, I preferably form the skirt or flange of a sheet of metal formed to tubular shape and secured together at the longitudinal edges with a seam, as at 9, similar tothe forming' of a can body, and then securing the disk 5 in one end by interlocking the peripheral portion thereof with the edge portion of the body, as at l0.
The receptacle R is arranged with an annular shoulder located a short distance from the mouth of the receptacle which is preferably in the form of a bead 11 ordinarily arranged upon the neck of bottles. The flange or skirt of the closure is of a length t0 extend beyond said bead and the closure is secured to the receptacle by applying pressure to the top to forcibly hold the top against the sealing material and the latter against the edge of the mouth and then crimping the edge portion of the ilange below the-shoulder or around the head, as by rolling or otherwise, to seal and secure the closure to the receptacle.
To rele-ase the closure from the receptacle the skirt is provided with a rip or tearing strip. For this purpose the so formed body or skirt is arranged with the usual hooks ,to form the interlocking seam 9 to extend flange with the tearing stripA it is interf mediately and annularly scored. on a ,Zig Zag; or undulating line 15, this scoring line beingY f arranged so that the portion-16 (Figuiere) of the flange ivill engage` below the bead. while the intermediate portion 1l. `Willeirgage upon` or be inline with the high; portion of the bead. Tolrelease the closure the tab 1l is grasped by the fingers andby exerting a pull' thereon the flange Will.r be torn or disjoined on the zig: zag,v line, 15; To remove the closure from the receptacle, an axial pull is exerted thereon,` and asthe closure is madeof relativelyduotile niaterial the extended portion 161 will spring outwardly and ride-upon and over the body. Should it be desired to replacetlievelosure all: that is necessary is; tovv push the closure upon, the reeeptaeleby a: slightpressure.v of the hand, the portions 16 of the flange springing over and yieldingly engagingzv the reeeptaele bead not onlyl holding the clos-ure against accidental displacementlo'nt also maintaining afsubstantially. airtight seal between the sealing; materialfl' andthe mouth of the reeeptaele andntherjebyprevent' deterioration and spoiling of the contents remaining in thereceptac-le.
By the arrangement of the seann 9: as described the tab is formed* by 'ai portion of the sheet whichV ordinarily constitu-tes a part ofthe seaintlie'tabbeing of a length equal tothe portion oftlxe'sheet forming an. interlocking hook. off the sanievivliereby there is ai Considerable saving.; of. material which is aigreatv desideratum. in Closures-,of this character oonsideringirthe large qua-ntities in whieh they are-inanufaetured- Having thus-v deSeri-bed my invention, 1 claim:
