CLOSURE FOR CONTAINERS.

' Specification of Letters Patent.

' 7 Application filed April 2, 1917. Serial No. 159,140.

To all whom it may concern: Be it known that I, WILLIAM .J. Towns, a citizen of the United States, residing at St.

Paul,.in the county of Ramsey and State of arranged in connection with the inner seal if closure;

. and in ass'to". permit the discharge opening of the inner seal to be eitherclosed by the cap or exposed, as desired, topermit discharging,- removing or exposing the contents of the pvessel.

Tothis end v construction, combination, and arrangement 70f parts hereinafter described and claimed,

the invention; consists in the v In: the accompanying drawings-forming part of'this specification, p Figure 1 is a planview of improved Fig. 2 is a section on iline 22'-of' Fig.1.; Fig. 3 is a; perspective view oftheclo'sure shown a bed to the wall oiia container -po it n? Fig. 4 is a perspective view of my closure shown in connection with a portion of a' eontainer wall andv hew n the cap in losing position in withftliefcut away in-- ner seal;

.' Fig. 5 isa view of the innerseal illustrating af portion thereofbroken away; and

.Fig. 615 a perspective view of -a' su pport- 'ing neck for the'closure forming the dis charge nozzle for the container,

In the accompanying dr'awmg s,I show one form ofmy invention, A represents a 1 neck suitablysupportedby the wall '2] of ,the

container, the neck A surrounding the discharge opening of;the container. The c0ntainer forming nopart of the invention-"is not shown. ,The neck A'is forined, adjacent to its free witk'aj surrounding exterior groove 3, forming a rim 4 at the free edge of .the neck, the edge 5 of the neck rimbeing I In carrying out'my-invention I provide an preferablyturned inwardly.

inner seal B in the form of a cap, the annular wall 6 of the cap being fitted over the end of the neck A, with the free edge 7 of the wall 6 crimped into the groove 3, to hold the inner seal firmly inplace. The top wall 8 of the'cap B ordinarily forms a closure or inner seal for thecontainerneck, as illustrated by full lines in Fig. 2. When it is desired to open theinner seal a portion 9 of the sealing PATENTKFQFFICE; i

Patented Mar. 11, 1919.

wall 8 is cut away from the surrounding rim and bent downward1y;'as shown in Fig. 5. I

preferably use a material in the inner seal that can be easily cut, and also for the 'urp pose hereinafter pointed out preferably orm the sealing wall 8 with a central transverse outwardly projecting rib 10 separating the part of the wall which is to be cut away and bent down, from 'the 'portion of the wall which is left uncut. t

An exteriorcap C, preferably of the con structlon shown, lnclosessealing cap B, and

cap 0 and cap B'nnay be secured toneclc A' in one operation or ca'p B may besecured to the neck separately and cap C set over cap B and secured to neck Ain another operation.

The cap 0 in the drawings is shown romea of a slngle piece of metal doubled upon itself" to constitute a double wall 11' surrounding the neck with the lower edge of the wall bent into the groove 3. The exterior cap C is;

loosely sup orted onthe top ofsealingcap B so as to e freely rotatable thereon,- The inner portion of the double annular wall of the cap 0 is carried up over the top of the sealing cap B as shown in Fig. 2 and a desired portion-and shape is cut out to act as a guide for cutting out the inner seal and to form a discharge opening 12 adapted to be.

brought into registration with the cut-away opening in the inner seal. v

Forthe purpose-of forming a pouring spout I show the cuter portion of the annu-.

lar wall of the cap bent outwardly and upwardly to form a flange 13. Any suitable way of rotatably securing the exterior cap C upon-the neck may be employed, as for ex ample,prongs upon the lower edge of the annular wall of the cap 0 may be bent inwardly into the groove in the neck A. The cap C may also, as desired be made without a spout, and in this .event cap C Wlll be made with a single annular wall, having discharge same and the free edge of the annular wall 6 of the sealing cap crimped into groove 3,

holding the sealing cap B firmly in position.

The exterior cap C is then fitted over the inner sealing cap and neck and secured in a suitable manner against removal while, at

the same time, allowing free rotation upon the neck. To permit the rotation of the cap C, I. preferably utilize the groove 3, as by bending the prongs 14 from the loweredge of the annular wall of the cap 0 into said groove.

When it is desired to discharge the contents of the container the cap C will be turned so as to bring the opening 12 over the portion of'the inner seal that it is desired to cut away. The portion 9 of the inner seal below the opening 12 is then, as shown in Fig. '5 cut away and bent down into the neck or may be cut away and entirely removed. The contents of the container may then be freely poured from the registering openings in the inner seal and the outer cap. When it is desired to close the opening in the inner seal the cap C may be turned to bring the solid top portion of the cap in closing position over the opening of the inner seal. The construction as shown is simple and eas of op eration, convenient and cleanly, an as cap C does not come off, it cannot get lost to leave contents unprotected. While I have shown the inner cap B formed of'a single piece of metal I may form the cap B with the portion 9 already cut away using separate material, as paper, which will ordinarily be so connected or arranged in connection with the top wall 8 of the inner cap as to form a tight seal but whichmay be'cut away to form an opening in the inner sealing cap which will register with the opening 12 in.

the outer cap 0. The drawings also show rib 10 in inner seaL. This may however be made with or without the rib as desired.

Ido not restrict myself to any particular or specifie'use of my invention, as to liquid,

semi liquid or dry materials nor as to size, whether it be smaller than size of container vor full size of container and further as to construction and shape of inner and outer caps nor neck within the scope of the invention, as defined in the following claims.

I claim:

1. A closure of the class described comprising in combination, a neck and a cap fitted thereto and formin a normally conineck, both caps being ermanently secured to the neck, sald second cap being with an opening exposing a portlon of said inner cap, and permitting the same to be cut away to form registering openings for'the purpose set forth. v

2. A closure of the class described comprising in combination a neck, and a cap permanently secured over the end of said neck and formed with a breakable seal normally closing the same, and a second cap rotatably supported over said inner ca and permanently secured to the neck, sai rota table. cap being formed with an opening exposing a portion of the closing seal of said inner cap, the exposed portion of the closing provided ported over -said first cap, said second cap being provided with an opening exposing a portion of said inner cap and permitting the same to be cut away to form registering ogenings, and said outer cap having its lower e ge upturned thereabout and flared ou wardly into a pouring spout.

4. A closure of the class described comprisin in combination a neck and a ca secure over the free end of said neck an formed with a breakable wall sealing the same, an exterior cap rotatably secured over said inner cap and neck, said rotatable cap being formed with an opening for the purpose set forth, and a transverse rib projecting outwardly from the sealing wall of said nner cap to define the portion of said sealing wall to be broken away.

5. A closure for containers, comprising an inner cap having a to wall divided by an upwardly projecting dhordal rib into a removable segment and a fixed segment, and an outer cap having a top wall formed with a segmental shaped opening registerable with the removable segment of the inner cap wall.

. 6. A closure for containers, comprisingan inner cap havingv a ordal-.rib into a removable segment and a fixed segment, and an outer cap having a top wall formed with a segmental shaped opening registerable with the removable segment of the inner cap wall, and a solid portion seatin on the chordal rib whereby the latter w1ll constitute a barrier against the passage of the container contents between the cap walls in either position of the cap.

7. A. closure for containers comprising an inner cylindrical member, and a cap member having a cylindrical flange 'inclosing the member, said flange being bent outwardly 1,200,110 a i a and upwardly upon itself and flared outwardly about the top thereof to form a pouring spout.
