CLOSURE DEVICE.

Application filed March 28, 1922.

7 '0 all whom it may concern:

Be it known that I, LOUIS R. ONEILL, a citizen of the United States, residing at No. 835 Clinton Avenue, in the city of Newark,

county of Essex, State of New Jersey, have invented a new and useful Improvement in a Closure Device.

One important object of the invention is to provide a device that will be securely 10 connected with the container not only when in a position to close the discharge orifice, but also when removed therefrom, so that it can not become detached and lost. In this connection it may be pointed out that the positively connected character of the device is protection against its acquiring dust, dirt and germs, as a result of accidentally falling or being placed in unsanitary surroundings.

Another advantage which is obtained in the use of a ositively connected closure device of this c aracter is that the contents of the container are protected against the detrimental effect of continued exposure to the atmosphere due to loss or misplacement of the closure device. This advantage is particularly marked in the case of ,containers with liquids or other substances which quickly volatilize or evaporate when exposed to air.

. Likewise, it may be pointed out that the device may be readily applied to the conventionally made tube without involving any change in its method of manufacture.

The device is of comparatively simple construction. Brieflydescribed it consists of a cylindrical collar or sleeve with a smooth inner side, designed to slide along a smooth exterior wall of a discharge nozzle,

on the lower part of which sleeve are mounted two diametrically opposite verti cal arms supporting a cup-shaped top with a screw threaded inner wall, designed to revolve about an upper exterior threaded part of the discharge nozzle. As the cap is rotated about the nozzleof the container, so as to move upward, the closure rlevice is raised and may be swung on the pivots away from the orifice of the tube. 'In clos- 5. ing the orifice, the cap is swung back to the vertical and is rotated downwardly.

For a fuller understanding of the invention, reference is to be had to the following description and accompanying drawings.

Serial No. 547,583.

Fig. 1 is a side elevation with the closure in a closed position, and Fig. 2 is a longitudinal sectional view partly in elevation taken at right angles to Fig. 1.

Referring in detail to Figs. 1 and 2, the letter A designates a tube or container of conventional construction provided with a cylindrical discharge nozzle, a, which is exteriorly threaded at its upper part, but has a smooth lower part and is formed with a discharge orifice, b. A cylindrical sleeve, 15, is designated to frictionally slide along the smooth surface of b, on the lower part of which sleeve are situated two trunnions, diametrically opposite and designated 4 and 5.

The closure element, B, consists of a circular dish, 6, with a cylindrical rim, 7, reseinhiing a cup with two ears, 8 and 9, extending downward and substantially at right angles to 6, which are pivotally connected with the sleeve, 15, by means of trunnions, 4 and 5, which may be either placed in the sleeve, 15, or afiixed to the ears, 8 and 9, as shown in Fig. 2, in which case they would engage in the sleeve, as

engage and shown at 16, and thus secure the closure The device is operated by grasping the closure member when it is in a closed position, at the, top between the thumb and forefinger and by turning same until the screw threaded portion of the cap is raised free of the screw threaded part of the nozzle. The closure element may then be raised to a sufficient height above the top of the nozzle to permit it to be swung to either side thereof. The closure member, B, is then swung to either side of the nozzle away from the orifice to allow the free discharge ofv the contents of the container. It may be observed that as the cap is raised upwardly, it is prevented from becoming separated from the nozzle as the lower band comes in contact with the threaded part of the nozzle,

To replace the closure member in a closed position, it is swung to the vertical position over the container and the cap is screwed downward until the top of the closure member rests snugly against the discharge noz-,

zle, at

The substance out of which the device may be constructed may be any material that can be advantageously utilized for the purpose of providing a closure device of the within description, sheet metal being prefer able because of its practical'utility and inexpensiveness.

Having thus described my invention, what I now claim and seek to protect is as follows:

A container closure, comprising a discharge nozzle having a smooth cylindrical portionand an exteriorly threaded portion of a greater diameter than the threaded portion, said smooth portion being substantially longer than the threaded portion, a sleeve mounted on the nozzle, and provided with a pair of oppositely disposed openings, and an interiorly threaded closure cap having a pair of downwardly extending and converging arms formed integral with the cap and adapted for pivotal connection with the sleeve, said sleeve being of a width that will permit the cap to clear said discharge nozzle when swung to and from its closed position.

This specification signed this 23rd day of March, A. D., 1922.
