F. H. JOBSON CONTAINER AND CAP THEREFOR Filed Dec. 28, 1950 FIG.

mvszvrozm FREDERIO H. JOBSON Patented Aug. 18, 1953 UNITED STATES PATENT OFFICE CONTAINER AND CAP THEREFOR Frederic H. J obson, Atlanta, Ga.

Application December 28, 1950, Serial No. 203,049

8 Claims.

This invention relates to a container, and mor particularly to a container of the type commonly referred to as a collapsible tube, such as is employed for containing tooth paste, shaving cream or the like.

The primary object of the invention is to avoid the loss of the closure cap for the container and to assure its association at all times with the container for ready movement into and out of closing relation with the discharge opening of the container.

Another object is to move the closure cap into and out of closing relation with the discharge opening of the container by the simple movement of an element of the device in a rectilinear path across the discharge end of the container.

Still another object'is to facilitate the rapid assembly of the closure cap with the container and the actuating slide member.

The above and other objects may be attained by employing this invention which embodies among its features a closure cap carried by the container for movement in a curved path into and out of closing relation with the discharge opening of the container, a slide member carried by the container for movement in a path which intersects the curved path, means carried by the slide member for movement into intersecting relation with the curved path and engagement with the closure cap to hold said closure cap in closing relation with the discharge opening of the container, and means carried by the closure cap and engageable by the slide member for moving said closure cap out of discharge opening closing relation upon movement of the closure cap retaining means out of the arcuate path.

In the drawings:

Figure l is a fragmentary edge view of a container and closure cap embodying the features of this invention;

Figure 2 is a fragmentary sectional view through a container illustrating this improved closure cap and slide member in place thereon, with the closure cap in closing relation to the discharge opening of the container;

Figure 3 is a View similar to Figure 2 illustrating the slide member retracted and the closure cap moved to open position;

Figure 4 is a view similar to Figures 2 and 3 illustrating the parts in another position;

Figure 5 is a view similar to Figures 2 and 3 illustrating the manner of assembling the parts;

and

Figure 6 is a perspectiveview of the closure cap andactuating arm and lugs therefor,

Referring to the drawings in detail a conventional collapsible tube Ill is provided at one end with a head Ilia having therethrough a discharge throat I2 adjacent which is formed in the head a chamber I l. The chamber I4 opens outwardly adjacent the discharge end of the throat I2 through the top surface I20, and the top edge of the wall of the chamber remote from the throat I2 is provided with a notch E6 the purpose of which will hereinafter appear. As illustrated in the drawings, the discharge end of the throat I2 is inclined toward the body of the container It as it recedes from the longitudinal axis of the container to form an inclined seat It for engagement by the closure cap to be more fully hereinafter described. The container is provided on opposite sides of the throat I2 and chamber with dovetail grooves 22 (Fig. l) and at opposite ends with transversely extending grooves 24 and 2B.

A closure cap 28 is provided at one end with a perpendicular flange 30 for entrance into the groove 26 and carried by the opposite end of the closure cap 28 is an actuating arm designated generally 36 which is received in the chamber It as will be readily understood upon reference to the drawings. A layer of suitable sealing material 38 is carried by the cap 23 between the flange 30 and the arm 36 for engagement with the inclined end It of the discharge throat I2 in order to form a tight seal therewith when the cap is in closed position. The end of the arm 3% adjacent the cap 28 is made relatively heavy and extends at an obtuse angle relative to the cap. As the arm recedes from the angular extension it curves in the direction of the plane of the top of the cap and is provided at its end remote from the cap with a fulcrum lug 43 which is adapted to enter the notch I6 previously referred to and form a pivot about which the cap moves in a curved path away from the throat I2. An actuating lug 42 is carried by the arm 36 at the end thereof remote from the cap 23 and projects in a direction opposite the lug it as will be readily understood upon reference to the drawings.

Mounted for sliding movement on the container head ltd in the dovetail grooves 22 thereof is a slide member designated generally i l and provided adjacent one end with a recess 36 which opens toward the container It and is provided with a cam Wall 38 which is adapted to engage the lug 42' as the slide member :34 moves in a rectilinear path which intersects the path of movement of the closure cap 28. Carried by the slide member 44 adjacent the end thereof remote 3 from the recess 46 is a closure cap retaining member 563 which is moved with the slide member into and out of intersecting relation with the curved path in which the closure cap 28 is moved into and out of sealing relation with the seat I8 of the discharge throat l2. As illustrated, the cam 48 is so located and shaped that as the slide member it is moved to retract the closure cap retaining means out of intersecting relation with the curved path of movement of the closure cap, the actuating lug 42 of the actuating arm 36 is moved downwardly to place the arm 36 under tension and seat the fulcrum lug til in the notch IE. Substantially upon the instant of withdrawal of the closure cap retaining means from its projection into the path of movement of the closure cap, the cam 4-8 contacting the actuating lug d2 will cause said lug to rock about the fulcrum lug iii} in the notch l6 and move the closure cap out of closing relation with the seat it, thus exposing the discharge opening in the throat if to permit the contents of the container it to be dispensed through said opening.

When the desired amount of material has been removed from the container in, the slide member 4a is moved to advance the closure cap retaining means toward the curved path of movement of the closure cap, thus permitting the weighted end of the arm 38 to move into the chamber l4 substantially as illustrated in Figure 3 and upon further movement of the slide member M, the closure cap retaining means will be advanced into intersecting relation with the curved path and contact with the closure cap to force it into sealin relation with the seat 48.

In assembling the parts, the lug ill is seated in the recess or notch it with the actuating arm 3-8 lying substantially parallel with the end of the container iii. The slide member 44 is then engaged with the dovetail grooves 22 and advanced across the actuating lug 32 toward the throat l2 and in end closing relation with the chamber M. Obviously as the closure cap retaining means moves into closure cap retaining position, the arm 36 will rock about its fulcrum is into substantially the position illustrated in Figure 2.

By thus moving the slide member, the closure cap retaining means iii) is advanced into and out of intersecting relation with the curved path through which the closure cap 28 moves and when said closure cap retaining means lies in intersecting relation with said path, the closure cap 25 will be held in sealing relation with the seat it? of the throat 12.

In the preferred form of this invention the arm 3a; is made of a resilient material so that the cam 48 can place the arm under tension and the instant that the closure cap retaining means 55 moves out of the curved path, the closure cap 28 will spring upwardly away from the seat i8 to break the seal therewith.

While in the foregoin there has been shown and .des ribed the preferred form of this invention, it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.
