Description

Nov. 15, 1932. w. G. KENDALL 1,888,174
DISPENSING DEVICE FOR CQLLAPSIBLE TUBES Filed March 11, 1932 ATTORN EY Patented Nov. 15, 1932 UNITED STATES WILLIAM G. KENDALL, F MAPLEWOOD, NEW JERSEY DISPENSING DEVICE FOR COLLAPSIBLE TUBES Application filed March 11, 1982. Serial No. 598,248.
This invention relates to dispensing devices, and particularly, to devices for collapsible tubes or other containers, the object being to provide an improved construction which will maintain the tube normally closed, but will automatically open when the tube or container has been actuated for dispensing some of the contents.
Another object of the invention is to provide a dispensing device for collapsible tubes wherein the device includes a cap for normally closing the tube, the same being formed to be easily applied and removed, and at the same time to automatically function to permit a discharge of the contents of the tube without the admission of air.
Another object, more specifically, is to provide a dispensing device for collapsible tubes which is formed of rubber and by the consistency of the material is normally closed, the same being formed with a portion which may fit directly over the end of a collapsible tube or may have a threaded liner adapted to be screwed thereon.
In the accompanying drawing,
Figure 1 is a side view showing part of a collapsible tube with the discharge end in section and an embodiment of the invention applied thereto.
Figure 2 is a side view of the dispensing device shown in Figure 1.
Figure 3 is an end view of the device shown in Figure 2.
Figure 4 is a view similar to Figure 1 but showing a slightly modified form of the dispensing device.
Figure 5 is a sectional view of a further modified form of dispensing cap.
Figure 6 is a detail fragmentary sectional view showing part of a collapsible tube and a cap associated therewith.
Referring to the accompanying drawing by numerals, 1 indicates a collapsible tube of any desired kind, the same having an exteriorly threaded neck of substantially the usual construction. It is evident that the invention could be applied to other containers without departing from the spirit-of the invention, 50 and that the tube or container may contain any liquid or semi-liquid material, the same to be dispensed through the neck 2.
As shown in Figure 1, the neck 2 is exteriorly threaded so as to receive the interiorly threaded sleeve 3. This sleeve is provided with a conical-shaped end 4, having a restricted discharge opening 5. The dispensing ca 6 is fitted over the sleeve 3 with its extension 4, and is held thereon by adhesive or any desired means. The base 7 of the cap 6 50 is tubular and merges into a cone-shaped portion 8, which has integral therewith a flattened section 9, the flattened section 9 having a slit 10.
It will be understood that the cap is made from flexible rubber, or other flexible material, so that when the tube 1 is collapsed more or less, the material therein will be projected through the opening 5 and against the interior of the cap 6, whereupon the parts will give so that the slot 10 will open and permit a ischarge. As long as the pressure continues, the discharge of the contents will also continue, but immediately upon cessation of the pressure on the tube 1, the resilient action of member 9 will stop the discharge and will gradually close the slit 10. In this way thecontents may be readily discharged but will be immediately shut off when sufficient has been secured, and in addition the orifice will be sealed by the rather tight closing of the slit 10 through the resilient action of the rubber FThen the tube 1 is empty, the cap 6 with its metal lining may be readily unscrewed from the neck 2 and screwed on to the neck of another tube, and in this way used on many tubes. 8
In Figure 4, a slightly modified structure is provided wherein the metal ring 3' is only the length of the base 7 Aside from this feature, the structure is the same as shown in Figure 1. Under some circumstances, the device could be used with a difierent form of neck, as for instance, the neck 11 shown in Figure 6. This neck is provided with an enlarged bead 12, over which the base 13 is forced when the cap is in use. It will be seen that the constricted portion 14 of neck 11 substantialy fills the tapering part of the cap 6', so that the discharge is almost immediately against the parts in which the slit 10 is located. It will be evident that the cap 6', as shown in Figure 5, could be used on container 1, as shown in Figures 1 and 2, without dearting from the spirit of the invention, the
Ease 13 fitting snugly over the threaded part of the neck 2.
I claim 1. A dispensing device for containers comrising a rubber cap cone-shaped portion having a discharge slit at one point and a tubular body, and a metal sleeve firmly fitted into said tubular body, said sleeve being formed with a tubular portion having threads for engagement with part of said container and a cone-shaped portion engaging the under surface of the cone-shaped portion of said cap for preventing collapsing thereof.
2. A dispensing device of the character described comprising a cap having a tubular body, said body tapering into a cone-shaped formation, said cone-shaped formation being provided with laterally extending flanges, said flanges merging at the end of the coneshaped member, said flanges being provided with a slit extending into the interior of the cap, and means for removably securing said cap to a container.
3. A dispensing device for collapsible tubes and other containers providing a cap and a metal connecting member, the cap being pro vided with a tubular body tapering to a pointed formation, the tapering portion of the cap having oppositely extending flanges merging at the top of the tapering portion, said flanges and tapering portions belng slitted to provide a normally closed discharge opening, said metal connecting member ineluding a threaded portion adapted to be removably connected to said tube or other container and a cone-shaped extension fitting against the cone-shaped part of the cap interiorly thereof.
4. A dispensing device formed of resilient rubber for collapsible tubes, containers, and the like, said dispensing device comprising a tubular body adapted to removably engage part of the tube or other container, a tapering portion and a double flanged portion merging into the tapering portion and with each other, said double flanged portion being slit to provide a discharge 0 ening.
