PASTE DISPENSER l John P. Marcy, Cresskill, N. J. Application May 14, 1942, serial No. 442,901

1` Claim.

This invention relates to receptacles for storing and dispensing materials in paste form and has for a primary object to provide a paste dispenser having a body of pliable fabric material, a head of rigid substance provided with a delivery port for the material; and means mounted on the body for longitudinal movement therealong whereby upon manual manipulation, VVthe contained substance witln'n the body is forced from the same.

This invention has for one of its important aims to provide a dispensing tube for paste or the like, which tube is formed of fabric capable of being flattened by structure mounted thereon for movement longitudinally thereof, which fabric material is gripped by the means to preclude displacement in a direction opposite to that ejecting the paste.

A further aim of this invention is the provision of a paste dispenser of the aforementioned character, the parts of which are capable of being formed from materials available and that are not expensive to obtain nor assemble.

At the present time dispensing tubes for paste are created from tin or metal that is pliable when drawn to a thin sheet and which does not have the property of seeking an original tubular form after being compressed to force the material from the body of the tube. In view of the present economic situation respecting such aforesaid metal, it is desirable to substitute materials therefor in the production of paste tubes which will serve the same function of preserving the paste against deterioration, holding the paste in condition for extrusion by slight pressure on the tube body and maintaining the bulk of paste Within the tube combined near one end thereof as the quantity is decreased. Accordingly, a dispenser made to embody the present invention is preferably manufactured in a form as shown in the accompanying drawing, wherein:

Fig. 1 is a side elevational View of a paste dispenser embodying the present invention.

Fig. 2 is a longitudinal central sectional view through the dispenser taken on line II-II of Fig. 1.

Fig. 3 is a cross sectional view taken on line III-III of Fig. 1 and looking in the direction of the arrows.

Fig. 4 is a fragmentary elevational View of a paste dispenser made in accordance with a modied form of the invention.

Fig. 5 is a cross sectional view taken on line V--V of Fig. 4, looking in the direction of the arrow; and

Fig. 6 is a View similar to Fig. 5 but with the ISIS Vmeans for holding the body in a fiat condition, released from its operative position.

When constructing paste dispensers from materials contemplated, the body 8 will be substantially tubular in form and made of fabric now obtainable on the open market, capable of conning a paste within body 8 without permitting escape thereof through the side walls of the body. In some instances, the fabric is closely woven cotton material, impregnated with water-proofing substance.

One end of tubular body 8 is closed through the medium of a clamp I0, U-shaped in transverse cross section and pressed to position as shown in Fig. 2. The other end of body 8 is provided with a head I2 of rigid substance through which an outlet opening I4 is formed. Head I2 may be of metal, plastic or other material capable of maintaining its form and being held in place by any desired medium.

An inturned marginal edge at the end of body 8 and indicated by the numeral I6, will overcome any tendency of head I2 to move outwardly after it has been assembled with the body.

A cap I8 closes outlet opening I4 and since this cap forms no part of the invention, the same may be screw-threaded or otherwise removably affixed to preclude accidental escape of the paste material from within body 8.

It has been found that fabric material, now available, will seek an original tubular form because of its resilient character. Heretofore, the tin or similar substance from which tube bodies have been created, was primarily pliable and retained the form into which it was pressed. It has previously been unnecessary to provide a follower or means for holding the dispenser body in a flattened condition where the paste therein is maintained at the end thereof, near outlet opening I4. Best results are obtained with a fabric body 8 when followers, such as illustrated herewith, are mounted thereon.

The preferred form of the follower comprises a pair of opposed rollers 20 having a length slightly greater than the width of body 8 when flattened as shown in Figs. 1 and 2. These rollers 20 are joined at their ends by links 22 serving as bearings for rollers 20 to permit free rotation thereof about their axes.

While rollers 20 would normally maintain a position holding the contents of body 8 near head I2, it is desirable to provide means for preventing accidental movement of rollers 20 in a direction toward clamp I0. This means is in the nature of a pair of yokes 24, the legs of which are pivotally Nr w 2,358,989 Y 3, but its physical character will readily indicate secured to links 22 by pins or analogous means 2B that serve to join rollers 20 with said links. The bight of yokes 24 is yieldably urged against the outer faces of the walls of body 8 when such have been formed by flattening. Spring 28 is of sufficient strength to cause yokes 24 to grip the fabric material from which body 8 is a part of the follower assembly. Teeth 30 created in the bight of yoke 24 are contoured to permit movement of rollers 20 toward head l2 When pressure 'is exerted on ear 32 by the finger or thumb of the user.

Figs. 4, 5 and 6 illustrate a simpler form of follower. This follower is in the nature of a U- shaped clamp U10, the free Vends of the legs whereof are provided with inter-engaging elements |02 and |04. Body |06 of this tube is embraced by clamp |00 and the friction relation between the members will preclude accidental movement toward the empty end of the body.

Obviously, this form of clamip isnot as convenient to operate as the one illustrated in Figs. 1, 2 and that this invention contemplates means other than the preferred embodiment for holding body 8 in a condition where the contents thereof will not become accidentally misplaced.

The substance from which body 8 is made will not maintain a form when rolled, therefore, some type of follower must be combined therewith.

Having thus ldescribed the invention, what is claimed as new and desired to be'secured by Letters Patent'is': v Y

In a follower of the character described for a,

dispensing tube; a pair of cooperating members for flattening the tube therebetween; links for operably connecting said iiattening members; gripping members pivotally connected to said links and engaging opposite sides of the flattened tube for preventing return movement of the follower toward the flattened end of the tube; and yielding means for urging said gripping members into engagement with the tube.
