RECEIPTACLE-CLOSURE.

Patented July 29,1919.

Application filed February 2, 19 17. Serial No. 146,186.

To all whom it may concern:

Be it known that 1, ROBERT A. RUSSELL,

a citizen of the United States, and resident of the borough of Manhattan, and State of New York, have invented a new and useful Improvement in Receptacle- Closures, of which the following is a spoolfication.

This invention relates to improvements in receptacle closures, with the object in view of profiding an arrangement of this nature in which the'cap or closure may be applied to the receptacle with great rapidity and held in sealing position thereon against accldental displacement.

Anothe object consistsin providing such an arrangement in which the closure or cap may be applied to the'receptacle, so as to enter into sealing contact tllGlBWlth, by a simple axial movement, while the disassociation of the closure and receptacle may be efi'ected manually, by arelative rotary move- 1 ment of the two. 1

A further object consists in providing such an arrangement in which auxiliary 1nterlocking means is fitted to insure-the positive retention of the closure in sealing engagement with the receptacle.

A still further object consists in providing certain improvements in the struction and arrangement of the parts whereby the above mentioned and other objects may be effectively attained.

A practical embodiment of my inventlon is represented in'the accompanying drawings in which: c

Figure 1 represents a side view, partly in section, showing the closure in disenga association with the receptacle.

shape, such as are commonly fashioned upon' the necks of catsup bottles. 65 The closure or cap is represented by 4,

may operation and is shown; as substantially cylindrical in form, with a fiat top, and of such a size as to conveniently cooperate with the receptacle 1. Thls cap 4 may known spinning operation, or it may be formed of a plurality of separate elements,-

top interlocked with each other, or of any other suitable or approved construction. In the present instance, I have illustrated it as unitary. This closure 4 has a screw-thread 5 fashloned in the side walls of its body portion for cooperative engagement with the threads 3 upon the receptacle noted that, while the pitch of the threads 3 and 5 is substantially the same, the depth of the thread 5 is considerably less than that of the thread 3, as is clearly shown in section,

dditionally, the closure 4: may be composed f some relatively elastic or springy material, such, for instance, as'sheet iron, whlle the receptacle 1 will generally and naturally be composed of some unyielding, vitreous material, such as glass.

By reason ofthe points just mentioned, viz: the difference in the threads 3 and 5, and the s'pringy nature of the closure, it is perfectly feasibleto force the latter into sealing engagement with respect to the receptacle 1, by a simple axial movement, as is, indicated by the arrow in Fig. 1.

course, this axial movement needs only to be 'a relative one; that is, the closure 4 may be forced on to the receptacle 1 while the latter remains stationary; or the receptacle v1 may be forced into the closure 4, while the latter or both the closure-4 and the receptacle 1 may be simultaneously moved axially with resp and in opposite directions. movement, however, the threads 5 spring over the threads 3, so that the closure 4 may be firmly seated upon The fact that Such an oper ation is much more expeditious than the norof screwing the closure on the receptacle, cannot be gainsaid.

As anadditional sealing means, a disk 6 maybe interposed between the top of the closure-4 and the mouth of the receptacle 1, as indicated in dotted-lines, Fig. 2;. and this disk may conveniently be composed of During this be of integral construction', such as results from the well ect to each other;

it may be engendered,"

1; but it should be sure 4 and receptacle 1, nevertheless, there,

is a suflicient normal inter-engagement be V tween the threads 3 and 5, so that relative rotary movement between the closure 4 and receptacle 1 will generate relative" axial movement therebetween, in the usual manner; or, in a more simple phrase, so that the closure 4' may be screwedon or off the receptacle 1.

interlocking the; closure and receptacle, when in sealing engagement, I provide a band 7 which may conveniently be com posed of some relatively ductile sheet metal, which band has its upper end turned down- Wardly and inwardly for engagement with the upwardly and outwardly turned rim of the closure 4, as clearly shown at 8. After the closure and receptacle have been forced into sealing the band 7 may be crimped under the beading 2 on the receptacle, as clearly shown in Fig. 2. When the receptacle is received by the consumer, it is simply necessary to seize the closure in the ordinary manner and unscrew the same. During this manual-opera tion, the inter-engagement of the threads;3 and 5 will be sufiicient to move the closure 4 axially away from the receptacle 1, even against-the restraining influence of the band 7, the lower torted from its crimped condition, shown in Fig. 2, to substantially the. form shown in Fig. 1. Thisband may then be removed from the closure4 and discarded. if desired, the band 7 may be ripped off from the closure ,andreceptacle, before unscrewing the former, by the use of any ordinary andsuitable implement; but I intend that it shall be normally disengaged from the beading '2 by the unscrewing of the'clo sure 4, as described. v As a means for assistingthe manual gripping of the closure 4, it may be provided, on

its outer surface, with a' milled effect, consisting of an annular band of vertical corrugatiogs or excrescences, as shown at 9 in in! element' sealing of the receptacle, by means of the simple axial movement as distinguished from rotary movement, becomes of magni-. d

fied importance, when viewed in connection upon hundreds of thousands en mi lions of receptacles; and yet .I have succeeded in providing an arrangement which effects such saving, without decreasin the perfect sealing en agement between, t e closure andreceptac e, and without depriving the house- -As an additional and auxiliary'means of engagement, the lower edge of portion of which will be dis- Of course,

time saved during thewith thefperfo'rmance of asealing o eration which it is difficult to unseal when received.

; It will be understood that various changes may be resorted to in the form,construction, composition and arrangement of the several parts without departing from .the spirit and scope of my inventiomand hence I do not intend to be limited to the details herein shown and described except as. they may be specifically included inthe clalms.

What I claim-is: v 1. In combination, a receptacle and a closure therefor, the two having cobperative threads adapted, when mutually engaged, to 80 enable the closure to berotated 'intoand out of sealing engagement with the receptacle,

the thread on one of the two being-temporarilydistortable so that direct relativeax'ial movement may be enforced without rupture or-injury. 2.

the thread on the closure being shallower than the thread on the receptacle and the 010- sure being composed of springy material, so that direct relative axial movement may be enforced without rupture or injury 5.

the thread on the closure'being shallower than the thread on the receptacle, so that II'QCb'IBlMZlVG axial'movement may be enforced without. rupture or injury, and auxiliary means .for locking the closure in sealing engagement with the receptacle, said auxiliary means being arran ed to be disengaged from the receptacle y rotating thk closure out of engagement therewith.

6.

In testimony that I claim the foregoing as my invention I have signed my name this 1st 15 day of February, 1917.
