CLOSURE FOR COLLAPSIBLE TUBES AN D THE LEE.
0 Application filed Apri1 18,
This invention relates to closure devices for collapsible tubes and the like and has for its object to provide an efficient device which will enable the tube to be promptly opened and closed and sealed air tight. without the necessity of removing any part of. the device. I
A preferred embodiment of the invention herein disclosed consists of a. cap constructed for attachment to the nipple of a collapsible tube and provided with an opening and a floating valve'of cylindrical shape fitting within a counterbore formed in the nipple of the collapsible tube, and so arranged that after the cap is'slightly moved away from'the tube and on pressure being applied to the tube, the contents of the tube may be forced past the valve and out of the outlet opening of the cap. But when said cap is in closed position the contents of the tube cannot be forced past the valve, as the valve securely closes the opening in the nipple, also making it air tight and provides -a secure seal.
With this and other objects of my invention in view, I hereafter describe the embodiments of the invention shown in the drawings and finally claim the same.
Similar characters of reference indicate corresponding parts throughout the various views.
In the drawings collapsible tube provided with a closure constructed in accordance with my invention, and with the cap in closed position;
Fig. 2 is a simlar view with the cap in open position;
Fig. 3 is a plan view of the cylindrical valve; 1
Fig. 4: is a plan view of the washer having a circular opening, which opening is not necessary;
Fig. 5 is a plan view of the cap;
Fig. 6 is a central sectional view of another embodiment of Figure 1.
Referring to thedrawings, the collapsible tube 10, shown in Figs. 1 and 2, and shown as bIOken away, may be of any suitable construction, as it is well known and heretofore generally used on the market.
The collapsible tube 10 is provided with a nipple 11 having screw threads 12 arranged exteriorly thereof and being provided with an annular recess 18between the threads 12 and the end of the tube 10.
Fig. 1 is a central sectional view of a..
1922. Serial in. 555,144.
the cap extending inwardly from t e lower edge of the cap 14. The cap 14 is provided with an elongated opening or slot 16' and with interior screw threads 15 engagingthe exterlor screw threads 12. The nipple 11' is provided with the usual, central bore for the discharge of thecontents of the tube 10,
and is recessed annularly within the bore into which fits an annular spun li 18" of at its upper end to form a cylindrical guiding bore 13, which may be slightly tapering outwardly. As shown in the drawing, the circumference of the iding bore 13- is tapered upwardly an d outwardl very slightly like the inverted frustum' o a cone and adjacent to the circumferential wall of the bore 13 is arranged a substantially horizontal seat 19.. On this seat is arranged a washer 18 of a diameter substantially equal to'the smallest diameter of the bore 13, though it may be slightly smaller in diameter. In the event that the circumferential wall of the bore 13 is made c lindrical rather than conical, the exterior diameter of the washer 18 is substantially equal to the diameter of the bore, though it may be slightly smaller in diameter.
Upon the washer 18 is arranged. a cylindrical valve 17. The washer 18 is made of suitable material, such a compressed cork, rubber, stiflened paper or the like, and the valve 17 .of any suitable metal. The exterior diameter of the valve 17 is substantially equal to that of the washer 18, so thatin effect the washer 18 and valve 17. operate as if they were an entity. The upper portion of the valve 17 seats flat y against a plane portion of the under, interior surface of the 914. The diameter of the top of the valve is such as-not to overlap the" opening 16 of the cap. I
When the cap 14 is in the position shown in Fig. 1, it presses the valve 17 and washer 18 downwardly tightly against the seat 19,
making a perfect seal, and thereby prevents any of the contents of the tube 10 from passing between-the valve and washer and the seat, so that a tight closure is obtained. The washer 18 and the valve 17 may, if desired, be made of one piece, instead of two, and may be composed in their entirety of metal, com ressed cork or other suitable material, ut I have found especially advantageous results to follow from the use of the rigid metallic member 17 and the yieldable material '18.
When it is desired to eject a portion of the contents of the container 10, the cap 14 is slightly rotated. By this rotation the cap. 14 is removed from the valve 17 as the capv andvalve are independent entities and v of the cap 14, thereby providing a passage between the washer 18 and the walls of the recess 13 through which the material may pass to the outlet opening 16 of the cap and hence be ejected from the tube. After a suitable quantity of the material has been ejected and it-is desired to close. the tube again, the cap 14 is rotated in. the opposite direction until the washer 18 is seated on the seat 19 and held tightly thereagainst by the pressure of'the valve 17 and the cap 14. The fiat top of the cap and the flat surface valve abut against each other. The tapered circumferential 4 wall of the bore 13 has the advantage that it enables the valve 17 and washer 18 to be readily guided into proper position, but I have found equally advantageous results to follow from a recess having a cylindrical circumferential wall. When a cylindrical recess is used, the valve 17 and washer 18 are guided in the cylindrical recess, and the material is squeezed out through the space between the washer 18 and valve 17 on the one hand, and the walls of the recess on the other and out of the orifice 16 as the valve is slightly smaller than the recess in the nipple.
In Fig. 3 I have shown a plan view, as heretofore stated, of the cylindrical valve 17; 'in Fig. 4 a plan view of the washer 18 and have shown a circular opening 18 inthe washer which enables the squeezed material to get in between the washer and valve should the washer stick to its seat. But the opening is not essential and may be disposed with. I
In Fig. 5 I have shown a plan view of the ca with the elongated opening 16 arrange at one side thereof.
In the manufacture of my improved closure, the hollow ca drical with a knur ed hard grip, and after it has been threaded upon the nipple 11, its lower end may be bent or spun inwardly to form the annular flange or lip 18". .It
will be apparent, however, that any desiredmethod of'making and assembling the parts may be employed 'without. departing from the principles of the invention.
In F i 6 I have shown another embodiment, w ich follows quite closely the em- 14 may be made cylinbodiment of Figs. 1 and 2,. but has the nipple provided'with a circumferential depression ,forming a shoulder 41. By the downward movement of the cap 14 with the valve 17 and with'its washer 18,the washer is pressed against the shoulder 41 and being of yieldable material is forced into thedepression and hence gives a very tight fit so as to act as an efficient seal. 0
- From what has been stated above, it will be noticed that the cylindrical valve is in continued engagement with its guiding recess 13 and moves with the material, as the material is forced out of the outlet opening 16; also that when the cap is closed it serves to secure a perfect seal.
I have shown various embodiments of my invention, the details of which may be changed without d'epartingfrom the spirit thereof, as defined in the appended claims. Having described my invention, I claim as new and desire to secure by Letters Patent:
1. A closure for collapsible containers comprising an outwardly threaded nipple having a central bore forming a passage way through it and an enlarged bore extending inwardly from its outer end providing avalve seat, a cap having a threaded engagement with said nipple and provided with a discharge aperture offset from its center, and a valve mounted in said enlarged bore in the nipple between the valve seat provided therein and the inner'side of said cap.
2. A closure for collapsible containers, comprising an outwardly threaded nipple havin a central bore forming a passageway tllBI'EtTlIOUgll and an enlarged bore extend ing inwardly from its outer end providing a Valve seat, a cap having a threaded engagement with said nipple and provided with a discharge aperture offset-from its center, and a valve and an annular washer loosely mountedin said enlarged bore in the nipple between the valve seat provided therein and the inner side of said cap.
3. A closure for collapsible containers, comprising an .outwardly threaded nipple having an enlarged bore adjacent to its end providing a valve seat, a cap having a threaded engagement with the exterior of said nipple and provided with a discharge aperture offset from its center, and a valve and an annular washer loosely mounted between said nipple and saidcap.
In testimony that I claim the foregoing;- as my invention, I have signed my name hereto.
