Figure 3 is a view similar to Figure 2, but with In the form of the invention illustrated in the parts or the closure shown in a different oper- Figures 1 to 4, a closure designagenerally aiive p i y the. reference-numeral 1 is shown detach- 5 ably connected to a collapsible tube 2. The closure, preferably formed of rubber or similar flexible material, has a body 3 generally cylindrical in cross section. The lower end of the body 3 is inwardly beveled to form aninclined annular wall 4 adapted to flt snugly on the upper inclined end of the tube 2.
The tube 2 is provided with a neck 5 having an outwardly extended flange 6 adapted to seat over a shoulder '7 formed in the interior of the body 3. Above the shoulder 7 the body 3 is shaped to form a chamber 8 having a top wall 9 from which depends a valve stem 10 which is suitably secured to the aforesaid top wall by means of a depending pin 11 cemented, or otherwise secured, in a bore 12 (see Figure 4). The lower end of the stem 10 is enlarged to form an outwardly extending flange 13 adapted to seat snugly in an annular valve seat 14 formed at the lower end of the neck 5 of the collapsible tube 2.
The upper end of the body 3 where it extends from the wall 9 is generally triangular in cross section. This upper end 15 has a projecting lug 16 formed at one side thereof. The body 3 is provided with a slot 17 which is normally closed by the natural resilience of the material from which the body 3 is made. The body 3 and the valve mechanism connected thereto are so arranged and constructed that when the flange 13 is seated in the annular seat 14 the slot 17 is closed.
In order to move the valve 13 from its seat and to open the slot 17, it is only necessary for the operator to press downwardly on the projection 16. This pressure not only moves the valve 13 away from its seat, but also causes the slot 17 to gape and thereby permit the discharge of fluent material from the collapsible tube 2. The form of the invention just described is adapted to be forced onto the neck of a tube of standard construction; the naturally resilient parts yielding suflficiently to permit them to be properly assembled on the neck.
In the modification shown in Figure 5, the closure body 18 is formed integral with a collapsible tube, which, of course, will be made of the same elastic material. The body -18 is provided with a top 19 somewhat similar to the top 15 of the modified form described above. A stem 20 depends from the top 19 and has suitably secured to its lower end a valve closure 21 adapted to seat snugly against a flat face 22 formed at the upper end of the tube 23.
The valve 21 comprises a comparatively heavy body 24 from the center of which extends a cylindrical projection 25 adapted to receive the lower cylindrical end 26 of the stem 20. The end 26 may be suitably secured in the cylindrical projection 25 by cementing these parts together or by any other suitable means. The cylindrical projection 25 may be reinforced by any desired number of radial ribs 27 which extend adjacent to the outer periphery of the body 24 and serve as guide means for properly positioning the body 24 on the seat 22.
In the modification shown in Figure 6, the body 28 of flexible material is detachably connected to the neck 29 of a collapsible tube 30. The lower end of the body 28 is beveled or countersunk at a greater inclination than the inclination of the upper end of the tube 30; and is shaped to form an annular bead 31 which seats under the flange 32 which extends outwardly from the upper end of the neck 29. The body 28 is shaped to form a chamber 33, from the upper member 35.
.wall of which a valve stem 34 depends to be connected suitably at its lower end to a valve The valve member 35 comprises a comparatively heavy body 36 having an outwardly directed flange 37 adapted to seat against an annular flat valve seat 38 formed at the lower end of the neck 39. r The upper end of the body 28 is inclined to form a triangular member 39 which may be depressed, as indicated by the dotted line, to open the valve 35 and the slot 40 formed at the junction of the member 39 with the main part of the body 28.
In the form of the invention shown in Figures 7, 8, and 9, the closure comprises a cylindrical part 41 internally screwthreaded at its lower end to engage the external screwthread on the neck 42 of a collapsible tube 43. The part of the body 41 adjacent the neck 42 preferably is formed of vulcanized rubber, while the upper part is necessarily formed of flexible material. The upper end of the body 41 is of conical shape and is provided with two slots 44 and 45 which may be caused to gape by a lateral and downward pressure on the apex 46 of the closure.
A valve stem 47 depends centrally from the conical end of the closure; and at its lower end is suitably secured to a valve member 47 adapted to seat against the valve seat 48 when pressure is removed from the upper end of the closure. Obviously, when the valve 47 is in closed position the slots 44 and 45 must also be closed.
In the modification shown in Figures 10 and 11, the body 49 of flexible material is substantially cylindrical throughout its length. The lower end 50 of said body 49 is sharply countersunk so as to make a close flt with the upper inclined end 51 of the collapsible tube 52. The interior of the body 49 is shaped to form a chamber 53 closed at its upper end by a wall 54 from which depends a valve stem 55 having a valve 56 suitably secured to its lower end to move toward and from a valve seat 57 formed at the lower end of the neck 58 of the said tube. The top wall of the chamber 53 is provided with slots 59 and 60 which are normally closed by the resilience of the material, but which may be caused to gape by lateral and downward pressure on the upper end of the body 49. Obviously, such pressure will also cause the valve 56 to be moved from its seat;
The modification shown in Figures 12 and 13 is somewhat similar to that shown in Figures 7, 8 and 9. The body 61 of this closure is internally screwthreaded at its lower end to engage the external screwthreads on the neck 62 atthe upper end of a collapsible tube 63. The body 61 is shaped to form a cylindrical chamber 64; and the top wall of this chamber is inverted V-shaped in cross section. A ridge 65 extends lengthwise of the aforesaid top and provides the means whereby the top may be moved in opposite direction to cause the slot 66 or the slot 67 to gape for the purpose of discharging material from the closure.
A valve stem 68 depends from the center of the top, and at its lower end is suitably secured to a valve 69 having an annular flange 70 extending outwardly therefrom to seat in an annular groove 71 formed at the lower end of the neck 62. As shown in Figures 12 and 13, the valve 69 is secured by a staple to the lower end of the stem 68.
In the modification shown in Figures 14, 15 and 16, the closure comprises a hemispherical 72 of flexible material having a stem 73 depending ofthe stem 73 and are upper part it will -flange when the latter threaded to receive to a valve r fromthe center thereof with a spring '13 sur-- rounding the stem. The lower end of the body '12 fits snugly over the upper end' of the neck '14 extending upwardly from the upper end of a container I5. The stem '13 is connected at its lower ,end to a valve 74' which includes a flange 75' adapted to seat against the flat face 76 formed at the lower end of the neck 74. Slots '1'! and '18 are formed in the body '12 on opposite sides the material and by the pressure of spring '73" when the valve '74 is in closing position against the seat '16. The operation of this form of the inventionis quite similar to that of the previously described form.
P1111 this form of the invention the valve '14 is provided with a circumferential flange '15 which it' will be observed under-laps the neck '74 preventing removal of the closure. The closure was silience of applied by forcing the valve '14 down through the neck 74 with the flexible flange l up-folded with respect to the upper part of the valve, which beobserved is cut away or smaller in diameter so asto make room for the is upfolded. After the flange 75' has expanded as in the position shown in Figure 15, the closure cannot be subsequently removed, for the bottom portion of the valve '74 is made of a diameter approximately that of the neck 74 leaving no room for the down-folding of the flange '15.
In the form of the invention shown in Figures 17,18 and 19 a substantially cylindrical body 79 has a skirt 80 at its lower and internally screwthe externally'screwthreaded upper end of a collapsible tube 81. The body 79' is provided with an intermediate recess 82 having its innerwall beveled to correspond with the slope 83 of a flange 84 formed between the ends of the valve member 85. A flange 86 is formed between the ends of the body '19 to facilitate the assembly of the body on the upper end or the tube 81. p
, The valve member 85 has its flange 84 clamped between the-shoulder 8'? of the body 29 and the upper edge of the flexible tube 81. The valve member 85 also has downwardly directed a frustoconical valve seat 88 adapted to receive the conical face of a valve 89 suitably secured at the lower end of a stem 90 which depends from the center of the top 91 of the valve member 85 and issurrounded by a spring 120. The lower part a of the valve member 85 may be rigid; but it is necessary that the upper part be flexible in order that the slots 92 and 93 may be opened whenever pressure is applied to the central button 94. It will be obvious from an inspection of the drawings, that when the center of the top 91 is depressed, the slots 92 and 93 will be caused to gape, and thereby permit the egress of material from the interior of the valve member 85.
The form of the invention illustrated in Figures 20, 21, and 22 is somewhat similar to that illustrated in Figures 1'1 to 19. In this form, however. the valve member 95 is made throughout of flexible material in order to permit its intermediate flange 96 to be sprung into the intermediate recess 97 formed in the body 98, which is internally screwthreaded at its lower end to receive the externally screwthreade'd upper end of the flexible tube 99. v
A valve stem 100 depends centrally from the flexible top 101 of the valve member 95. At its lower end the valve stem 100 is suitably secured 102 adapted to be moved by pressure closed by the normalrevtical with that shown in Figures applied to the top 101, from its seat 103 formed at the lower end of the valve member 95. The top of the valve 95 is provided with slots 104 and 105 which arenormally closed by the resilience of the material whenever the valve 102 is in' 6 closed position on its seat 103. It will be evident that pressure applied to the top 101 will cause the slots 104 and 105 to gape at the same time as the valve 102 is moved from its seat 103.
In the form of the invention shown in Figures 23 and 24, the valve member 106 is made ofresilient material; and at its lower end is provided with a flange 10'! adapted to be clamped against the inwardly directed annular flange 108 formed at the upper end of a collapsible tube 109. As 16 shown in Figures 23 and 24. the flange 106 is formed at the lower end of a cylindrical recess 110 which is internally screwthreaded to receive the screw threads or a clamping nut 111 which is provided with recesses 112 adapted to receive correspondingly shaped pins of a sparmer commonly used to rotate nuts of this character. The valve member 106 is shaped to provide a flat top 113 which terminates in a slot 114 where the top joins the side of the member 106. The lower wall 1150f the member 106 is shaped to form a seat for a valve portion 116 formed integrally with the member 106. The operation 0! this form of the invention will be apparent from inspection of Figure 24 of the drawings which shows 80 the valve member 106 distorted to move the valve 116 away from its seat 115 and to cause the slot 114 to gape for the purpose of permitting material to be expelled through the slot 114.
The parts are so constructed and designed that 36 her.
In the form of the invention illustrated in Figures 25, 26, and 27, the valve member 106 is iden-' 23 and 24. In this case, however, the flange 107 is clamped to the upper end 117 of a collapsible tube 118 by means of a flanged nut- 119. The construction and mode of operation of this form of the invention will be obvious from an inspection of the drawings.
