Application November 13, 1951, Serial No. 255,913

2 Claims. (Cl. 222-498) The present invention relates to a closure and it particularly relates to a combination snap-top, screwtype closure particularly applicable to bottles.'

Although the present invention has abroad application to screw-top, snap-type closures of the combination type, it has a specific application to closures for cosmetic, pharmaceutical and liquid condiment containers where it is desired to have the closure readily removable as by a screw or bayonet connection to permit re-iilling of the bottle, and where it is also possible, by a simple manipulation, which does not remove the cap from the bottle, to permit dispensing of small quantities of liquid from the bottle in connection with cosmetics, pharmaceuticals, ilavoring materials, perfumes, liquid dressing and the like. y It is among the objects of the present invention to provide a simple, inexpensive, durable, readily manufactured screw-cap for cosmetic containers or the like, which may be readily applied to seal the cosmetic container and ing the cap or closure.

Still further objects and advantages will appear in the more detailed description set forth below, it being understood, however, that this more detailed description is 'I giveny byway of illustration and explanation only and not by way of limitation, since various changes therein may be made by those skilled in the art without departing from the scope and spirit of the present invention.

In accomplishing the above objects, it has been found most satisfactory, according to one embodiment of the present invention,'to provide a plastic type screw cap which may be readily applied and removed from the bottle by means of a bayonet or screw-type connection.

The upper portion of the container desirably has a swinging hinge connection member which has a snap connection to a simple opening or spout through the top of the screw cap.

This central opening is of such a shape and size that small quantities of the liquid, whether it be a cosmetic, pharmaceutical, dressing or liquid material, may be dispensed by inverting the bottle, removing the screw cap and reciprocating the same.

Desirably, the bottle has a sealing means which will seal the spout or opening of the spout upon complete closure of the cap.

The spout is desirably so arranged that it may snap into a recess in the hinged, upper portion of the screwtype closure to assure complete sealing.

With the foregoing and other objects in view, the inice vention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views:

Fig. 1 isa side perspective view of a bottle or container which may be utilized according to a preferred embodiment of the present invention, showing the main body 'of the cap screw or otherwise connected to the bottle opening with the cover element removed from the top of the screw cap.

Fig. 2 is a transverse vertical sectional view upon the line 2-2 of Fig. l, upon a large scale as compared to Fig. l.

Fig. 3 is a side sectional view of the closure of Fig. 2, as applied to a bottle, showing the upper cap portion in closed position.

Fig. 4 is a side sectional view similar to Fig. 3 of an alternate embodiment of the present invention showing a different form of spring retainer for the spout nipple member.

Fig. 5 is a transverse sectional view upon the line 5 5 of Fig. 4.

Referring to Figs. l, 2 and 3, there is shown a bottle A which may be of glass or a pliable, plastic material,

having a screw cap B with a removable snap cover C.

Referring particularly to Figs. 2 and 3, there is shown a neck 10 for the bottle A with a screw formation 11 on the outside thereof.

This neck 10 is designed to receive the sleeve 12, which may be of a molded, plastic material having an interiorly threaded portion 13.

The outside of the sleeve has the depending apron 14. The lower edge 15 of the apron 14 should terminate a short distance above the top contour 16 of the bottle A.

Desirably, the sleeve 12 has a top, transverse plate member 15 molded `integrally therewith and there is inserted against the plate an intermediate element 16.

The intermediate element 16 supports the washer 17, which forms a tight contact with the top face 18 of the screw neck 10.

The screw neck 10 will be jammed against the periphery of the washer 17 to assure a seal.

The element 16 is recessed, as indicated at 25, to form ber 27.

The nipple member extends upward and mushrooms as indicated at 28, where it is received inside of the spheroidal head 29 of the male snap member 30. The male snap member 30 has an outstanding flange 31 which is attached to the base 32 of the recess 33 in the top of the cap B.

It will be noted that the washer 17, the intermediate element 16, the nipple 27 and the spheroidal head 30 have the through- passages 34, 35, 36 and 37, through which the liquid in the container A may be spurted upon inversion and reciprocation thereof.

Extending outwardly from one side of the sleeve 12 is the hinge member 45, which has an eye at 46 receiving the pivot pin 47.

The pivot pin 47 extends through the eye 46 and into the clevis jaw members 48 depending from and attached to the snap top C.

The snap top C consists of a molded plate 55 having the projecting forward portions 56, which serve as a finger or hand-manipulating member.

The recess 57 receives a supporting inset plate 58 which holds the female snap member 59 in position.

.t3 Thefemale snap member is received in a recess 60 fand-it has a Spheroidal recess member 61. The spheroidal recess member 61 receives the spherical cap or i, spherical, Ahead.:3(1,attachedjo.,theloyvecsereigkcap;,B

The cap P has the rearwardly extending members `91 which enclose the projecting portion 91 of the screw cap N.

The pivot pin 92 projects through the members 90 and 91 to form a substantially-permanent pivotal connection between the snap cap P-and the screw. cap N.
