1 Claim.

My invention relates to improvements in dispensing containers, more particularly tubes for dental, shaving, face creams, and the like.

The principal object of the invention is to pro V vide a simply constructed dispensing container in which all screw thread devices and rotary parts are eliminated and which is easily operative to extrude therefrom at each operation a uniform quantity of cream, or the like, is self-closing after each operation to maintainthe contents of the container fresh and pure, and adapted for inexpensive manufacture and replacement of parts.

Other and subordinate objects are also comprehended by my invention, all of which, to-

gether with the precise nature of my inprovemerits, will be readily understood when the succeeding description and claims are read with ref- V which slidably fits over the same for movement erence to the drawings accompanying and forming part of this specification.

In said drawings:

Figure 1 is a view in side elevation of my improved dispensing container in its preferred embodiment,

Figure 2 is a view in front end elevation,

Figure 3 is a view in longitudinal section taken on the line 33 of Figure 2,

Figure 4 is a view in transverse section taken on the line 4-4 of Figure 3,

Figure 5 is a view in transverse section taken on the line 5-5 of Figure 3,

Figure 6 is a similar view taken on the line 6-6 of Figure 3.

Figure 7 is another similar view taken on the line 1-1 of Figure 3,

Figure 8 is a view in longitudinal section of a modified embodiment of the invention,

Figure 9 is a view in transverse section taken on the line 9-9 of Figure 8,

Figure 10 is a similar view taken on the line I5Ill of Figure 8, and

Figure 11 is still another similar view taken on the line II-II of Figure 8.

Referring to the drawings by numerals, and first to Figures 1 to 7, my improved container, in its preferred embodiment, comprises a tubular body I of any suitable rigid material, such as glass, plastic, or the like, and having an open butt end, a discharge neck 2 provided with a lateral discharge aperture 3 at the base thereof, and a central externally beaded hand grip portion 4.

A cylindrical cup-like, end section 5 is slidably fitted over the butt end of the body I for sliding with a friction fit forwardly of the body forwardly and rearwardly thereon to open and close the discharge aperture 3. The cap I0 is provided withan axial bore I I and a hub I2, the former for receiving the front end 8 of the shaft ,6 and the latter slidably fitting in the neck 2.

A pin I8 extending transversely through the end 8 of the shaft 6 and through the cap I0 secures said cap to the shaft.

An abutment disk I5 loose in the section 5 is opposed to the butt end of the body I and provided with an axial aperture-I5 in which the base section 'I of the shaft 6 is slidably fitted.

A bowed leaf spring I6 is interposed between the closed end of the section 5 and the disk I4, said spring having a central aperture I! through which the section I of the shaft 6 slidably extends.

The leaf spring I6 urges the section 5 rearwardly of the body I with the closed end of the section spaced from the disk I4, whereby the ratchet shaft 6 is urged into a retracted position in which the cap I0 is correspondingly retracted on the neck 2 into closing position relative to the aperture 3, said cap I0 by engagement with the outer end of the neck 2 establishing the'normal position of the section 5 and the shaft 6.

Slidably fitted in the. body I and on the shaft 6 is an annular,- disk-like, follower I8. A pair of diametrically disposed resilient ratchet dogs I9 are provided on the follower I8 having the form of leaf springs, the outer ends of which are clinched in the follower, as at 20, and the inner ends of which are opposed upon opposite sides of the shaft 6 on the rear side of the follower to ratchet forwardly over said teeth 9 and snap in front of the same.

A bleed aperture 2| is provided in one side of the section 5 to discharge air therefrom.

Referring now to the use and operation of the described form of the invention, the body I is first filled, the section 5, shaft 6, disk I4, spring I6 and follower I8 then assembled as a unit with the body I, with the follower 18 in the butt end of the body, and the cap I is then attached to the shaft 6 by means of the pin I3. With the body I grasped between the first and second fingers of the hand and straddling the hand grip section 4, the section 5 is pushed by the thumb forwardly in opposition to the spring 16 thereby advancing the shaft 6 so that one of the teeth 9, by means of the ratchet dogs 19, picks up the follower l8 and advances the same a distance corresponding to that moved by said section 5. Such advance of the shaft 6 advances the cap In to open the aperture 3 and the advance of the follower l8 forces a measure of cream out of the aperture 3. Upon release of the section 5, the spring l6 retracts the same to normal position and likewise the shaft 6. Such retraction of the shaft 6 correspondingly moves the cap [0 to close the aperture 3 and the tooth 9 in advance of the dog 19 under retraction of the shaft flexes said dogs rearwardly so that said tooth wipes rearwardly past the dogs in position to pick up said dogs and the follower l8 for another operation of the follower when the section 5 is again operated in the manner described. Thus, as will be seen, repeat operation of the section 5 causes a uniform quantity of the contents of the body to be expelled at each operation and the follower [8 may be advanced step-by-step.

In the modified embodiment of the invention shown in Figures 8 to 11, a plane shaft 22 is utilized in lieu of the ratchet shaft 6, the follower 23 is a plane disk without the ratchet dogs IS, the abutment disk 24 is apertured, as at 25,

to admit air into the body 26 behind the follower I 23, and a coil spring 21 is utilized between the closed end of the sliding section 28 and said disk 24. Also, the discharge aperture 29 in said section 28 is disposed so as to be closed by the body 26 when the section 28 has been moved forwardly sufficiently to open the discharge aperture 30. Further, an inwardly opening ball valve 3| is provided in the closed end of said section 28 to admit air into said section under rearward movement of the section.

In the use and operation of the described modified embodiment, air trapped in the section 28, after th aperture 29 has moved over the body 26 and been thereby closed, is forced through the apertures 25 in the disk 24 against the follower 23 to force said follower forwardly at each operation of the section 28 in a manner which will be clear, the follower forcing a measure of the contents of the body 26 out of the aperture 30. When the section 28 is released, it is returned to normal position by the spring 21 and air admitted thereto by way of the valve 3|.

The foregoing will, it is believed, suffice to impart a clear understanding of my invention both as regards structure and advantages thereof.

Manifestly, the invention is susceptible of modification in other respects than as herein disclosed, and right is reserved to all modifications falling within the scope of the subjoined claim.

What I claim is:

A dispensing container comprising a tubular body having a front end neck provided with a lateral discharge aperture, said body having an open rear end, a closure cap slidable on said neck forwardly and rearwardly to open and close said aperture, respectively, a closure disk loosely fitted against said open end, a cup-like section fitted over the rear end of said body and said disk for sliding thereon forwardly and rearwardly, respectively, a bowed spring in said section interposed between the same and said disk and tensioning said section against forward movement, a follower slidable forwardly in said body to force the contents thereof out of said aperture, and means operative by forward sliding of said section to correspondingly slide said cap and follower, said means including a ratchet shaft and ratchet dogs on said follower, said ratchet shaft being provided with circumferential rearwardly tapered teeth, and said dogs comprising leaf springs on the rear side of said follower wipingly engaging said teeth.
