5 Claims. (Cl. 222-103) This invention relates to a paste filled cartridge and complementary dispenser adjustable to dispense paste from the cartridge.

Paste-like commodities such as tooth paste, shaving cream and the like are particularly difficult to dispense conveniently. Such pastes are often too heavy to flow easily from a rigid container and in addition usually exhibit a tendency to solidify or cake unless kept in an airtight container. conventionally, such pastes are packaged in tubes made of a pliable metal and squeezed by hand to meter a desired quantity of paste as determined by the user.

A principal object of the invention is to provide a paste dispenser which may be conveniently mounted on a wall surface such as in a bathroom and arranged with an adjustable screw which causes pressure to be exerted against a pliable paste filled cartridge so that paste is dispensed from the cartridge upon adjustment of the screw, the device being so arranged that upon the paste being expended a new full cartridge may be installed conveniently without need of special tools or equipment.

Another object of the invention is to provide a paste dispenser with a fixed plate and sleeve arrangement with a paste filled collapsible cartridge disposed between a head plate of the sleeve and the fixed plate with a mechanism for forcing the sleeve head plate against the fixed plate to compress the cartridge and force a quantity of paste from an orifice of the cartridge.

A further object of the invention is to provide an improved dispenser employing an oval-shaped collapsible cartridge filled with paste and apertured through the center to receive a member engaged with plates on two sides of the cartridge.

Another object of this invention is to provide a novel paste dispenser which mechanically meters a desired quantity of paste from a cartridge to a brush employed by the user so that more accurate control of quantity of charge is obtained than heretofore.

A feature and advantage of the invention is its attractive adjunct to the usual bathroom fixtures so that it may, if desired, be employed as a medium of advertising for paste products or the like.

Another feature and advantage of the invention is its simplicity of installation, refill and capacity to take up a minimal space.

A still further feature and advantage of the invention is its self-sealing dispensing spout which eliminates troublesome screw-on caps conventionally used with paste containers.

Other objects of the present invention will become apparent upon reading the following specification and referring to the accompanying drawings in which similar characters of reference represent corresponding parts in each of the several views.

In the drawings:

Fig. 1 is a perspective view of the invention shown mounted on a wall surface with a portion cut away to show interior structure.

Fig. 2 is a sectional view of Fig. 1 taken along lines 22;

Fig. 3 is a bottom plan view of Fig. 1; and

Fig. 4 is a perspective view of a collapsible cartridge for use with the dispenser of Fig. l.

The preferred embodiment of the invention comprises a fixed oval plate 12 with a complementary shaped cylinder 14 slidably mounted on the plate. One end of cylinder 14 is capped by a head plate 16 forming a' compression chamber 17 interiorly of the cylinder Wall between fixed plate 12 and head plate 16. Fixed plate 12 is rigidly mounted on a bracket 18 by an arm 20 projecting laterally from the bracket to suspend the fixed plate in spaced parallel alignment with bracket 18. Arm 20 is centrally apertured along its central longitudinal axis as at 22 and there threaded to receive a screw 24. Screw 24 is slidably engaged with aperture 26 formed centrally in head plate 16 and passes through the center of com pression chamber 17 and an aperture 28 formed centrally in plate 12 to engage the threads of aperture 22. The head of screw 24 is flanged at 31 to frictionally engage with head plate 16. Flange 31 is formed with a finger grip 32 projecting laterally from flange 31 which may be used to turn screw 24 and to force head plate 16 against the fixed plate 12.

A paste filled oval cartridge 35 for the dispenser is formed of pliable material such as pliable plastic. The cartridge 35 is generally egg shaped and dimensioned to fit within compression chamber 17. An aperture 37 is formed through the center of the cartridge 35 disposed to align with

apertures

26 and 28 so screw 24 can pass through the cartridge to engage threads 22.

In operation bracket 18 is fastened on a vertical wall surface 33 such as a bathroom wall by screws 34. Cartridge 35 is disposed in compression chamber 17 with screw 24 in communication with arm 20 through cartridge center aperture 37. Cartridge 35 is provided with a centrally disposed downwardly depending spout 38 orificed at its tip, as at 39, to form a singular opening to the interior paste filled cavity of the cartridge. Cylinder 14 is provided on the bottom portion of its wall with an elongated notch 41 to receive the spout 38. When the cartridge is installed as shown in Figs. 1 and 2, spout 38 depends downwardly from the bottom of cylinder 14 through notch 41. Orifice 33 is of the self-sealing type wherein paste Within the cartridge 35 is allowed to pass through the orifice only under pressure.

When screw 24 is turned, head plate 16 is forced against fixed plate 12. This forces paste in cartridge 35 out of orifice 39 so that it may be deposited on an article such as a tooth brush 42. The screw type attachment facilitated by screw 24 provides a micrometer adjustment which allows close control of the quantity of paste metered from cartridge 35.

After the contents of cartridge 35 have been exhausted screw 24 is removed and cylinder 14 is withdrawn so that the expended cartridge may be discarded. A new paste filled cartridge 35 is placed inside cylinder 14 with its aperture 37 in alignment with aperture 26, screw 24 is then inserted through

apertures

26, 28 and 37 and screwed into the threads of aperture 22 wherein the device is again ready for use.

The bottom of bracket 18 is bent to form an outwardly projecting flange 46 notched as at 47 to receive conveniently and support tooth brushes 42.

Although the foregoing invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it is understood that certain changes and modifications may be practiced within the spirit of the invention as limited only by the scope of the appended claims.
