CLOSURE FOR BOTTLES AND THE LlKE.

Specification of Letters Patent.

Patented. March 26, 1907.

Application filed May 27, 1905. Serial No. 262,668.

l'u (I /l It'll/mt if may (7(1/LL'IJI'IL. I Be it known that 1., THOMAS C. BOOTH, a i citizen of the United States, residing at New York, in the county and State of New York, l have invented certain new and useful lml provements in Closures lor Bottles and the Like, of which the loll owing is a specification.

This invention relates to clo.-.ures for botl tles and other packages or containers from i which it is desired to remove frointime to i time comparatively sniall quantities of the contents. Tooth-powders and analogous preparations are usually put up and marketed insuch packages, and while 1 have such preparations more particularly in mind it is also my purpose to provide a container for liquids, particularly somewhat viscous liquids, such as lubricating and other oils.

The general objects of the invention are simplicity of construction and consequent cheapness in cost of manufacture and ease and positiveness of manipulation.

Closures of the class to which this inven tion appertains are generally provided with a pair of caps, one fitting over the other, the inner one stationary and the outer rotatable thereon, both provided with corresponding apertures adapted to register with each other at a certain point of rotation to permit of the discharge of a portion of the contents of the container, the the movable cap being rotated through a slight arc to separate the apertures and close the opening. These caps are frequentl y screw-threaded to insu re a tight lit and perfect sealing when closed, and generally one thereof is providedwvi'th a slot and the other with a lug or stopadaptcd to engage the ends of said slot to limit movement of one relative to the other and facilitate manipulasity for,inspcction, the extent to which the outer cap should be rotated to open or close. Thus separate means have been employed to insure a tight fit and to limit movement, while my invention contemplates a construction in which both the necessary friction and the desired limit of movement are provided by a single simple element. With the above and other ends in View my invention consists in the novel features, de tails of construction, and combinations of parts, as hereinafter described in detail, illustrated in the drawings, and particularly pointed out in the claims.

My invention will be-more readily understood by reference to the accompanying drawings, forming a part of this specification, and in which- Figure 1 is a top plan'view of a container with my invention applied thereto. Fig; 2isv a partly-sectional e evation of the same. Fig. 3 is a similar view from another side. Fig. 4 is a top plan view of theouter cap when the-container is closed or sealed. Fi s. 5 and 6 are detail views hereinafter escribed. Fig. 7 is a plan view of a perforated instead of an apertured cap. Fig. 8 and Fig. 9 illustrate modifications hereinafter described, and Fig. 10 illustrates the application of my invention to a container for liquids.

Referring now to the drawings in detail, numeral 11 refers to the body portion of a container, which may be of thin metal, wood, glass, or other material and of any preferred form. This container is providedwith the usual neck 12, which if the package is of metal may be a continuation of the material of the container and which terminates in a permanent closing-plate 13, or the neck may be provided with an interfitting cap or ferrule suitably secured thereon and forming substantially a continuation thereof. The closing-plate 13 is provided with an aperture 14, (in the preferred construction,) adapted toregister with a corresponding aperture 15 in the top plate 16 of the outer cap 17, which fits snugly over the neck or cap 12. Corresponding annular ribs or beads 18 and 1 form a -,connection designed to somewhat yicldingl)" withhold the cap 17 in place and permit of relative rotary movement thereof.

The plates 13 and 16 are not flat or plane surfaces, but are stamped into the form of similar corresponding spirals or helicoids the extremities of each being connected to orm the shoulder 20 and 21, respectively. The plates being superimposed, these shoulders will serve to limit rotary movement of the movable )late in one direction, while rotation of the pate 16 in the other direction Will cause said plate to ride up the inclined plane provided by the spiral or helicoidal form of the platelliw If-the movement of the plate 16 is through'a comparatively small arc, the major portion of said lates will remain in continuous contact. e efiect is obviously that of the screw, and as the plates are on account of the elasticity of the material of the i 10 caps yieldingly held against relative longitudinal movement by the ribs or beads 18 and 19 they will bind after a slight turn and become locked through friction, which may obviously be regulated by varying the pitch of the incline. The connection should be yielding to the extent of permitting rotation through an arc sullicient to separate the apertures, and thus eil'ect the sealing or closing of the-container.

, It will be apparent that the should be so located in the plates register, and the container is open when the shoulder-stops 20 and 21 are together. tationof the outer cap therefore will serve to simultaneously separate the apertures and. bind the plates together to effect a tight closure. The helicoidal form of the plates obviates the necessity for the employment of other forms of stops to limit movement when the container is in an open condition, as well as doin away with a screw-threaded connec tion. t is not essential, however, that the registering apertures be located in the tops oi the caps, as they may obviously be located in the sides thereof. Here of course there would be no gradually-increasim friction between the apertured walls; but it the outer cap be made to fit reasonably snugly there will be no leaka e and the spiral tops will act as stops. It will be furthermore apparent that I. may employ perforated plates, as indicated in Fig. 7, each provided with a plurality of smaller registering apertures 22 instead of a single one. Rotary movement of the outer cap 23 should obviously be more limited in the manner hereinbetore suggested in this construction. I may, furthermore, in the single-aperture construction provide the outer cap with a spout 24, as shown in Fig. 10, and thus adapt the device for use with liouids instead of powdered or granulated soli s. My closure would thus become a valve of simple form adapted tocheck the iiow of liquids from a spout particularly adapted for use in connection with oil-cans of various kinds for various purposes. I may also for the sake of appearance, if the broken-outer edge of the cap is considered objectionable, provide the outer cap or both thereof with a head 25, as shown in Fig. 9, the spiral configuration being limited to that portion of the plate or plates with in the bead.

apertures that they liol l l in slighlly-yielding contact,

Many other modifications of the minor del tails of my improved closure will doubtless readily s'ug est themselves to those skilled in unto set my hand in the presence claim as new and desire to secure by Letters Patent 1. In a container, the combination of a stationary up with an aperture therein, a cap having a corresponding aperture superimposed and rotatable on said stationary cap, the tops of said caps being in the form of interiitling spirals, and slightly-yielding means for preventing relative longitudinal movement of said ups.

2. In a container, the combination of a pair of superposed, inlcrlilling cups having rcgisicring apertures, one rolnlablc upon the other and yicldingly held against relative longitudinal movement, corresponding portions of each cap being inclined to the direction of movement.

3. In a container, the combination of a pair of superposed, inlerliiiing caps having regislerii'ig apertures, one rolal able upon the other and yicldingly held against relative longitudinal movement, the tops of said caps being of corresponding llclicoldnl form.

4. In a container, the combimilion, with a neck having a reduced aperture therein, of a cap rotatable on said neck having a corresponding aperture and adapted to scul said container except when said apertures rcgister, said cap and neck being provided with yielding means to check relaliw longitudinal movementand juxtaposed planes inclined to the direction of rotary movement.

5, In a container, the combination of a pair of superposed, interfiiting (ups having registering apertures therein, one rotatable upon the othe and yicldingly held against relative longitudinal movement, the tops of said cups beingin the form of juxtaposed spirals of one revoluiion with connecicd spiral ends. I

6. A valve comprising a pair of comigu ous, correspondingly-upcrlurcd plates having relative sliding movement one upon the other, said plates being inclined to the direction of movement and the i'iperturcd portions thereof being held in continuous contact.

7. A valve comprising a pair of contiguous, correspondingly-apcrlured plates having relative sliding movement one upon the other, said plates being hclicoidal in form, means for retaining said plates continuously and means for rotating one thereof upon the other.

In testimony of the foregoing l have hereof two witthe art to w ich it appertains, and therefore I ncsses.

do not desire to limit my invention to the specific construction herein shown and described.

Having thus described my invention,
