Eiled Mar. 29, 1957, Ser. No. 649,469
9 Claims. (Cl. 222-536) This invention relates to means for dispensing pastes and viscous fluids from tubular containers.
Materials such as tooth paste, shaving cream, medicinal ointments, cements, caulking and sealing compounds, etc., are packaged and sold in compressible metallic tubes. Such tubes roll up from one end and dispense the contents by extrusion thru an orifice in the opposite end which is sealed by a metal membrane integral with the neck of the tube and/ or a screw cap of metal or plastic threaded onto the neck. In dispensing such materials as tooth paste, the consumer removes the cap by unscrewing the same from the tube neck and squeezes out the desired amount of paste onto a tooth brush, thereafter replacing the cap to seal the end of the tube.
While tubular containers are handy to use, the cap is frequently mislaid or dropped on the floor during use thereby leaving the open end of the tube unsealed. This is unsanitary when the contents are to be used internally and also causes drying out of the contents of the tube.
Even when the cap of the tube is not mislaid or lost, excess material gradually builds up in the threads of the cap and on the shoulder of the tube which is unsanitary and wasteful of the material being dispensed.
We have devised means for dispensing extrudable materials from tubular containers without removal and replacement of a cap or other closure device.
Accordingly, it is an object of the invention to provide improved means for dispensing fiowable or extrudable materials from tubular containers. Another object is to provide a dispenser cap for tubular containers which does not require removal for dispensing. A further object is to provide a dispensing device which saves time in dispensing and improves the sanitary aspects of dispensing from tubular containers. It is also an object to provide a rapid dispensing device which facilitates sealing the tube end without cap removal or replacement. Other objects of the invention will become apparent from a c0nsideration of the accompanying disclosure.
In order to provide a full understanding of the invention reference is made to the accompanying schematic drawing of which Figure 1 is a side view of a tubular container, showing one embodiment of the dispensing device of the invention, in partial section; Figure 2 is a cross section of a dispensing device utilizing an adapter; Figure 3 is a top or plan view of the dispensing device of Figure 2; Figure 4 is a cross section of a dispensing device similar to that of Figure l; and Figure 5 is a top or plan view of the dispenser of Figure 4.
Referring to Fig. l, a flexible, compressible, tubular container is closed in conventional manner on the lower end and terminates at the opposite end in a threaded neck or nipple 12 which is provided with an axial passageway 14. A threaded cap 16 screws onto nipple 12 and clamps expanded (ball) section 18 of dispensing tube 20 against a cupped bearing and sealing surface 22 of nipple 12. Cap 16 is also provided with a bearing and sealing surface 24 which engages expanded 2,938,653 Patented May 31, 1960 section 18. Dispensing tube 20 is provided with a passageway 26 which aligns with passageway 14 of nipple 12 when tube 20 is axially aligned with tubular container 19. Nipple 12 and section 18 of tube 26 occupy a conduit through cap 16. When dispensing tube 20 is in the position shown, material (such as tooth paste) may be extruded thru passageways 14 and 26 by compression of tubular container 10. A recess 28 in cap 16 extends at right angles to the tube axis toward the cylindrical periphery of the cap. The outer end of tube 20 is blind and passageway 26 opens through a lateral side of the dispensing tube, leaving annular surface 32 surrounding the end of the passageway. After use of the dispensing device, tube 20 is rotated into recess 28 which contains a receiving and sealing means 30 for surface 32 of tube 20 comprising a depressed plain surface adapted to engage surface 32 uniformly around the outer end of passageway 26. A corrugated surface 34 on the outer blind end of tube 20 provides means for lifting this tube out of its recess, into dispensing position.
Figure 2 shows a device similar in most respects to the device of Figure 1 but with the added feature of an adapter 40 which screws onto the neck 42 of a tubular container such as 10 of Figure 1. This arrangement of dispenser cap and adapter is of general application to various tubular containers where a single dispensing device is to be used on a sequence or plurality of tubes and is not to be disposed of after each container is emptied.
In Figure 2, the expanded end of tube 20 comprises a cylindrical section 43 whose axis is transverse to the axis of the tube. A narrow projection 44 on the blind outer end of tube 20 is transverse to the direction of rotation of the tube and provides means for raising the tube out of its recess when sealed therein.
Figure 3 shows a top view of the device of Figure 2 and is self-explanatory. Figures 4 and 5 show a circular cap 46 as contrasted with the oval or elliptical cap of the first three figures. The expanded section 18 of tube 20 is spherical in this embodiment of the invention as in Figure 1.
In use, the dispensing tube 20 seals with caps 16 and 46 because of the close engagement of the surface 22 of the neck of the container (or adapter) around the passageway 14 therein and of surface 24 of the underside of the cap with the spherical or cylindrical surface of the expanded end of the tube. This prevents waste and drying out of the material in the container.
The expanded section 18 or 43 of tube 20 should be enough larger than the main portion of the tube to permit rotation of the tube into its recess 28 without causing the main tube section to bind on or strike the end of neck 12 or adapter 40. Figures 1 and 4 show cut-away section 48 on neck 12 and adapter 40, which provide ample clearance for the main tube section when the tube is in its recess.
A significant feature of the invention lies in the recess for the tube which permits sealing of the open end thereof without the necessity of a screw cap or other nuisance means for closing the tube end. Without this feature little of any advantage in the device would be obtained. If desired, a soft, resilient pad, such as one made of rubber, may be positioned on surface 39 to aid in sealing the open end of tube 20. It is also feasible to construct the end of tube 20 around the opening therein in the form of a truncated cone so that a narrow or sharp annulus of material (surface 32) uniformly contacts surface 30. Tube 20 may be of either circular or regular polygonal cross section.
Conventional plastic materials which are used for making tube caps are suitable for construction of the While the invention has been described in connection with a present, preferred embodiment thereof, it is to be understood that this description is illustrativeonly and is not intended to limit'the invention.
