COLLAPSIBLE TUBE VALVE CAP MEANS Filed Sept. 26, 1955 [NI/ENTOR. Mc'fiozAs J VUQD EL JA W1 In e55 ATTORNEY United States Patent O COLLAPSIBLE TUBE VALVE CAP MEANS Nicholas J. Vurdelja, Des Moines, Howa Application September 26, 1955, Serial No. 536,417
3 Claims. (Cl. 222-548) Thisinvention relates to collapsible tube cap means and more particularly to a means for valving the flowable material from the tube.
Collapsible tubes are universally used as containers for tooth paste, shaving cream, salve, paint, jelly, paste, glue and like. Many such items as tooth paste are used by an individual at least once each day. These tubes have a threaded orifice with a detachable cap threaded thereon. Obviously each time the tube is used the cap must be removed, laid aside, the required material squeezed from the tube, and then the cap replaced by being screwed back onto the tube. This procedure is not only a waste of time, but at least a certain amount of skill and attention must be given to start the threading of the cap back onto the tube. Also the use of both hands is required. A still further objection to the usual common tube cap is that it often becomes dropped or lost after its removal from its tube. All such caps must be given several complete revolutions relative to the tube for both removal and replacement.
Therefore, one of the principal objects of my invention is to provide a valve cap means for collapsible tubes that is never removed from the tube upon which it functions.
A further object of this invention is to provide a material tube cap valve means that requires only a one-half revolution from full open to a complete closed position.
A still further object of my invention is to provide a valve cap means for collapsible tubes that is yieldingly held in a closed condition.
A still further object of my invention is to provide a valve cap means for collapsible tubes that when material is forced through the same will have a flat bottom and in cross-section a rounded top.
Still further objects of my invention are to provide a valve cap means for tubes that is economical in manufacture, durable in use, and refined in appearance.
These and other objects will be apparent to those skilled in the art.
My invention consists in the construction, arrangements, and combination, of the various parts of the device, whereby the objects contemplated are attained as hereinafter more fully set forth, specifically pointed out in my claims, and illustrated in the accompanying drawings, in which:
Fig. 1 is a side view of my tube cap means,
Fig. 2 is a longitudinal sectional view of my valve cap means in an open condition,
Fig. 3 is a longitudinal section view of the cap per se,
Fig. 4 is a side view of the tube neck or orifice with the cap removed,
Fig. 5 is an end view of the tube with the cap removed, and more fully illustrates its construction,
Fig. 6 is an end view of the tube with its cap in open position, and
Fig. 7 is an end View of the device with the cap rotated to a closed position.
in these drawings I have used the numeral 10 to desig- 2,808,971 Patented Oct. 8, 7
nate an ordinary collapsible material holding tube having a tubular neck or orifice projection 11. Ordinarily this portion 11 is threaded to take a screw cap. In my structure this portion 11 is not threaded but does have a peripheral groove 12 as shown in Fig. 4. This groove 12 extends substantially one half around the neck 11 and decreases in width as it approaches its right end. The free end of the neck is closed except for an outlet opening 13. The outer side of this opening is adjacent the periphery of the neck, is arcuate to conform thereto, and has its inner side straight, as shown in Fig. 5. This straight side of the opening is short of the dead center of the end of the neck. The numeral 14 designates a bathe fill inside the neck and which extends from the inside back portion'of the neck forwardly and inwardly to the straight side of the neck outlet opening, as shown in Fig. 2. This bafile has a flat surface terminating in common with the straight side of the outlet opening and aids and guides the passage of material through the neck, and out the opening 13.
I have used the numeral 15 to generally designate my cap, which is in the shape of an inverted cup and is of such size as to rotatably embrace the neck 11. On the inside of the wall of the cap is a lug 16 slidably extending into the groove 12. This projection 16 may be formed by any suitable means such as crimping, casting, or pinning. Its size is such as to freely slide in the groove 12 except near the right end of the groove where it decreases in width. Thus, as the cap is rotated to the right and as it approaches a closed position, as shown in Fig. 7, the projection 16 will become yieldingly wedged in the groove, thereby successfully holding the cap against accidental rotation from a closed position. The end of the cap is closed except for an outlet opening 17. This opening also has its outer side circular to conform with the periphery of the cap and its inner side straight as shown in Fig. 6. This fiat side is short of the dead center of the cap. The opening 17 conforms in size and shape to the opening 13, and registers with the opening when the cap is manually rotated to the left relative to the tube. When in such a position, and the tube is squeezed, the material therein will be forced through the openings 13 and 17 and upon exiting will have a shape similar to that of the openings, i. e., the material will have a flat straight bottom for engagement upon a toothbrush or like, and its upper surface will be circular in cross section. To open the cap valve means the cap was manually rotated a one-half revolution to the left. To close the valve cap means, the cap is manually rotated one-half revolution to the right. Therefore, the opening and closing of the unit is most rapid. When the unit is in a closed condition, the opening 17 will not be in register with the opening 13, but will be adjacent the enclosed end portion of the neck and the opening 13 will be adjacent the closed end area of the cap, as shown in Fig. 7. Ohviously, the cap is permanently secured onto the tube neck and can never become lost therefrom.
Some changes may be made in the construction and arrangement of my collapsible tube valve cap means without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
I claim:
1. In a device of the class described, a tubular neck, an end portion on said neck having an opening at one side of its dead center, a cup cap rotatably embracing said neck and having an opening in its bottom capable of registering with the opening in said end portion when rotated in one direction, a groove in the outer side of said neck having its width decreased near one of its ends,
and a projection on the inner wall of said cap slidably extending into said groove and dimensioned to be frictionally wedged in said groove when said cap is rotated in a direction to bring said projection into the decreased width area of said groove. V v
2. In a device of the class described, a tubular neck, an end portion on said neck having an opening at one side of its dead center, a cup cap rotatably embracing said neck and having an opening in its bottom capable of registering with the opening in said end portion when rotated in one direction, a groove in the 'outer'side of said neck having its width decreased near one of its ends, a projection on the inner wail of said cap slidably extending into said groove and dimensioned to be frictionally wedged in said groove when said cap is rotated in a direction to bring said projection into the decreased Width area of said groove, and a material guiding ibaffie inside said neck; said neck adapted to be part of a collapsible material tube.
