UNITED STATES PATENT OFFICE This invention appertains to new and useful improvements in closures and more particularly to a novel form of cap for collapsible paint or paste tubes.- V

The principalobject of the present invention .is to provide a sharp opening closure for a collapsible tube which will automatically open when subjected to the force of the contents of-the tube under pressure. Other important objects and'advantages of the invention 'will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a side elevational viewof the improved cap.

Figure 9 represents a top plan view of the form of the "invention shownin Figure 8. Figure 10 represents a side elevational view of the form 'of the invention shown in Figure 8.-

Referring to the draggngs wherein like numerals designate like pa it can be seen in Fig.-

ures

1,2 and 3 that numeral 5 generally refers to a collapsible paint or paste tube having a threaded neck 6; Numeral "l generally'refers to I the novel cap structure which is provided with a '7 these sidewalls '11 tapering upwardly as shown.

tubular portion 8 having a threaded end portion 9 engageable with theneck 6 of the tube 5. The

upper portion of the cap is formed to provide a vertical back wall 10, vertical side walls 11-11,

in Figure 2. The front wall 12 is inclined toward the back wall 10, in a direction to meet the upper end -of the said back wall 10. This front wall 12* is spaced at its upper end from the upper end-of ,the back wall 10 while the spring plate 13 retained against the front wall 12 by inturned lug 14 on the side walls 11 extends over the space between the upper end of the wall 12and the at the lower. edge of upper end of the wall 10 to normally close the same and to tensionally engage the upper end of the wall 10 as in the manner substantially shown 7 in Figure 2. Obviously, the spring plate 13 functions snugly between the side walls 11- -11 and 5 when the contents of the tube 5 are placed un er pressure when the tube being squeezed in the hand, the pressure of the contents 'againstthespring plate '13 will flex the same so as to permit some of the 2 the-upper end of the spring plate 13 and the upper edge of the back wall 10.

The form of the invention shown in Figure 5 is the same as'that shown: in Figure 1 with the ex-. ception instead of the lugs 14, an upturned flange 15 14a is provided 1 at the lower end of the front wall 12a and between this flange 14aand the front wall 12a the lower end of the sprin plate.

13 is engaged and retained.

.The form of the invention consists of a solid head So formed with a pasobviously sageway 18 through which paste or paint can be forced from the tube -5 to which it can be suitably attached. The upper portion of the. head 2 8a is inclined: as at 19. and upstanding flanges 11a11a are provided at each side of this inclined portion 19. 'Numeral 20 represents a rib the inclined portion 19 of the head while numeral 141) represents a cross pin between the lowernd portion of the flanges 11a as'rshownin Figure '1. Numeral 13a represents the spring plate which at'its lower end,-is

provided with a transverse corrugatidn' 13b which can be sprung betweenthe pin 14b and the rib 20. In this position the plate 13a is anchoredwith its upper end closing the upper end of the passageway 18.

The form of the invention shown in Figure 6 is similar to. that shown .in Figure 7 in that the head. at issolid and'provided-with the passage- 4 way18a. The top portion of this head 8b is provided with an inclined surface 19a against which the spring plate can bear so as to close the upper edge of the. passageway 18a.- NumeraliflOa represents an upturned name at the-lower end 45 of the inclined portion 19a, this flange. being spaced from the surface toaiford a pocket within which can engage the back turned portion 13d of the platelsc, this portion 13d tensionally engaging the end of the flange 2041 so as not to permit displacement of the plate 130, The plate 13c operates snugly between'the side flanges lib-+111);

Figure 8 shows the invention and same to expel between shownin Figure 7 20' 30 I a discharge opening through the extremity of is disposed over 'a discharge Opening said oblique endwith lindrical portion 8c having its upper portion cut ofl on an inclined plate. The body 191) extends inwardly of the side wall of the cap and has its .opposed side portion of the cap 80. The lower 13c abuts the transverse conthe flanges 11d and an elon- 22 at one end is secured as at the cap 80 while the other end the upper portion of the cap and disposed inwardly to tensionally bear against the intermediate portion ofv the plate 1.3e thus tensionally urging the plate against the projection 19b and the uppermost portion of the side wall of the cap. a

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit or scope of the invention as claimed hereinafter.

Having thus described my invention, what I claim as new is:

In combination, a container having a dis charge neck, said neck being cut off "obliquely, said oblique end being provided with a pair of parallel side flanges, said discharge neck having end of the plate tinuation lle of gated leaf spring 23 to the side of said oblique end with the remaining portion of the oblique end defining a rest, and a tension plate anchored at one end and adapted to fit snugly between said flanges and against said rest to normally close said opening.

2. In combination, a container having a discharge neck, said neck being cut off obliquely, said oblique end being provided with a pair of parallel side flanges, said discharge neck having a discharge opening through the extremity of said oblique end the oblique end plate anchored defining a rest, and a tension to normally close said opening, constructed of sheet metal and havingfa portion at the oblique end folded upon itself to provide a pocket for snugly receiving one end of the said tension plate.
