The invention relates to closure devices. It has for its main purpose to provide a closure device which may be used on all kinds of small containers, particularly such as are used for ltoiletl articles, like shaving cream, tooth paste, tooth` powder and the like. Its main object is to provide a device which may be readily opened and closed with the fingers of the same hand with which the container is held, so as to leave the other hand free to manipulate such other implement as may then be used.

Another object is to provide a closure device which is permanently attached to the container so that it cannot be lost or mislaid. Additional objects are to provide a device of neat appearance and simple and `sanitary construction, which will not materially add to the size of the container, which will enable all the contents to be removed from the container, and which can be vmanufactured at a low cost.

These and various other objects and advantages will be readily .understood from the following description and from the accompanying drawing of preferred embodiments in which, however, modifications may be made without departing from the scopeof the invention. In the drawing Fig.` 1 is a. front view of a collapsible tube tov which the closure device has been applied;

Fig. 2 is a side View of Fig. 1;

Fig. 3 is an enlarged, fragmental view of the tube and the closure device shown partly in crosssection;

Fig. 4 is another enlarged, fragmental side view showing the closure device in its open position;

Fig. 5 is another enlarged, fragmental view, similar to Fig. 4, but showing the closure device in its closed position;

Fig. 6 is a front view of the closure device used in combination with a bottle cap; and

Fig. '7 is a cross-sectional side view of Fig. 6.

In Figs. 1 and 2, the closure device is shown adapted to a collapsible tube I 0. An oblique face II is preferably formed on the tube and on this face the closure device is placed. It consists of a dove-tailed slide I2 on which a cover I3 is slidingly-mounted. This cover' has downwardly projecting flanges which engage in the dovetailed edges of the slide. An aperture I4 is formed near one end of the slide and communicates with the interior of the tube. The slide I2 is slightly wedge-shaped so that it is higher at the end I5 than at the endl I6. This is plainly shown in the enlarged views Figs. 3, 4 and 5.

The cover is provided with a finger grip I1 to facilitate its manipulation.

The closure device is operated by moving the cover fromone end of the slide to the other. When the cover is in the position shown in Fig. 5, the aperture' I4 is closed and consequently no material can be dispensed from the tube. When it is moved to the other end of the slide, as shown in Fig. 4, the aperture is exposed so that the material may be dispensed. By having the slide slightly wedge-shaped, the cover is rmly held in the locked position by friction, but can easily be opened by a slight force in the opposite direction. The wedge-shape also compensates for any slight wear which might occur by the constant movement of the cover.

To prevent the cover from being drawn over the end I6, any suitable means may be employed. In the present instance the corners I8 and I 9 have been slightly distorted by bending them upwards. This limits the movement of the cover.

By placing the closure device on the oblique face as shown, the whole device Ais contained within what would normally be the complete outercontour of the tube. Thus the tube can be laid on the side without any danger of the :linger grip touching the surface on which it is laid and thus accidentally become opened. In the same way the tubes may be packed without anydanger of the covers being dislodged from the locked position.

In Figs. 6 and 7 the closure device is shown attached' to a. bottle cap 20. This embodiment is particularly well adapted for dispensing tooth powder from a bottle.. In Fig. 7 the bottle cap is shown in vcross-.section while the cover is shown in full. In this case the nger grip 2| is shown in the center of the cover and the surfaces on both sides of this ringer grip are serrated to facilitate the manipulation of the cover. A pin 22 limits the downward movement of the cover. All other parts are numbered as in the embodiment previously described.

While I havestated that this closure device is particularly well adapted for containers for toilet articles, I do not thereby wish to limit the invention to such uses only, as it is evident that it might be used on containers for many other kinds of material. In like manner, while I prefer to place the closure device at an angle to the axis of the container, there may be cases where it is advantageous to place it parallel with the axis or even at the end of the container at right angles to the axis..

Having described my invention and ,its objects what I claim is new and wish to protect by Letters Patent is:

1. In a collapsible tube; a raised'and tapered slide formed integral with the body of the tube and having its opposite sides dove-tailed; an aperture formed in the large end of the slide and communicating with the interior of the tube; a. cap, having downwardly extending and dovetailed side members for straddlingsaid slide, slidingly mounted on the slide; the corners of the small end of the slide distorted, after the cap has been placed on the slide, to prevent the removal of the cap from the slide; and theslide located on an angularly-disposed face formed on the-side 0f the tube near the end thereof; said face s'o locatedthat the slide and the cap will not extend outside the circumference of the tube no1' outside its end.

2. In a collapsible tube; a raised and tapered slide formed integral with the body of the tube and having its opposite sides dove-tailed; an aperture formed in the large end of the slide and communicating. with the interior of the tube; a cap, having downwardly extending and dovetailed side members for straddling said slide, slidingly mounted on the slide; and the slide located on an angularly-disposed face formed on the side of the tube near the end thereof; said face so located that the slide and the cap will not extend outside the circumference of the tube nor outside its end.
