8 Claims. ((1222-193) This invention relates to closure structures for containers, and particularly to closure members formed, in substantial part, of flexible resilient" material.
- One of the objects of the'present invention is to provide a closure structure constructed largely of said. resilient material adapted, when flexed, to apply pressure to the contents of the container for dispensing purposes, together with a tube extending through the closure memberby means of which the con nts may be discharged, the structure being spe ially arranged to limit the possible movement of the dispensing tube.
Another object of the invention is to provide a closure member such as specified in the last preceding paragraph and wherein the flexible portion of the closure member is designed to have a predetermined varying degree of flexibility at respectively difierent locations thereof.
Other objects and advantages of'my invention will be apparent from the accompanying drawing and description, and the essential features thereof will be set forth in the claims In the drawing,

Fig. 2 is a top plan view of the closure of Fig. 1. Y
. Fig. 3 is a bottom plan view of the same closure.
Fig. 4 is a central vertical section of another embodiment of my invention, taken on the line I Fig. 5.
Fig. 5 is a bottom plan view from the line 55 of Fig. 4. I
Fig. 6 is a central vertical section of another embodiment of my invention.
Fig. '7 is a bottom plan view from the line 1-1 of Fig. 6.
Before the present invention. is described in detail, it is to be understood that such invention is not limited to the details of construction and/or the specific arrangement of parts herein illustrated and/or described, as the invention obviously may take other forms. It also is to be understood that the phraseology or terminology herein employed is for the purpose of description and not of limitation.
In Fig. -1, I show a closure member ID secured by a ring H to a container indicated in dotdash lines at l2. The particular form of the container is more or less immaterial as my closure member may be applied to various containers used for holding various materials. The
- container by flexure of the closure.
hemisphericalshape but it will be understood by those skilled in the art that I am not necessarily limited to this form.
The closure member In is provided with a depending thickened portion l3 which is perforated to accommodate a tube It communicating at its upper end Ila. with the closure exterior, and at its lower end IS with the container interior. A suitable removable ca-p l6 may be provided to seal the tubewhen not in'use. It is ap arent that the cap "5 may be removed, and material may then be expelled through the tube by manually flexing the closure l0 whereby pressure is brought to bear on the contents of thecontainer.
The closure 10 is provided with a more .resilient portion 10a, by reason of the fact that its cross-sectional wall thickness at the locationindicated by reference numeral Ilia is thinner than at other portions of the closure. If the closure is flexed by pressure at any portion of the top or rear, somewhat removed from the thickened affecting the position of the tube end IS.
The closure ll is provided with a flange portion H which extends outwardly and uninterruptedly about the periphery of the closure. It
will be notedthat the radially outer portion l8 of the flange I1 is of greater thickness than the radially inner portion i9 so that when the ring flange 20 is screweddown into engagement with the rubber flange l'l it engages the thicker portion iii of the rubber flange so as to insure a leakproof seal when-pressure is exerted on the The same result can be-achieved by making-the flange ll generally flat, but with a raised bead around its periphery.' I
Another embodiment of my invention is illustrated in Figs. 4 and 5. In this embodiment a flexible resilient closure 20 is provided with a thickened portion 2| depending therewithin as in the previously described closure. The closure cooperates with a disk, cap or diaphragm 22 to form therebetween a compression chamber, as will immediately appear. The disk 22 may conveniently be provided with a downturned an-' nular flange 24 'which has a forced fit over the upper edge of the container and a retainer ring 26 likewise has a forced fit over flange 24.
By means of an inturned rim 21 the ring 26 cooperates with disk 22 to retain therebetween a flange 28 on the cap 20.
The disk 22 is perforated'ito hold, in tight fitting relationship, .o'ne end '29 of tube 30, which tube extends downwardly into container 25 and 'is bent upwardly again to issue through the thickened portion'ZI of closure 20. Near the lowermost bent portion the tube is provided with one or more perforations or slots 3| the purpose of which will now appear. When pressure is applied to the chamber 23 by inward flexure of closure 20, a current of air is forcibly expelled through tube 30, entering at tube end 29 and issuing at tube end 32. The suction effect produced by this current past slot 3| draws a portion of the powdered or liquid contents of container 25 through slot 3| into the tube, whence it is forced outwardly through tube end 32.
The closureis provided with one portion 20a which is relatively more flexible than the balance of the closure, and the purpose and function of this more flexible portion has already been described in connection with the operation of the closure shown in Fig. 1.
Figs. 6 and '7 illustrate still another embodiment of my invention wherein a closure 35, a cap or disk 36 and a clamping ring 3'1 mutually cooperate to form a relatively leakproof compression chamber 38 as already described with reference to Figs. 4 and 5. In the present instance a tube 39 opens into the compression chamber at its upper end 40, and into the container at its lower end 4|, and a second tube 43 opens into the container at its lower end 42 and, on passing through a thickened portion 45 of closure 35, opens to the atmosphere at its upper end 44. The lower ends 4| and 42 of tubes 39 and 43 may conveniently be held together by sleeve 46 to constitute a relatively stable and inflexible assembly, or they may be soldered, welded, or otherwise joined, as convenient. As in the previously described embodiments the closure is provided with a relatively more flexible portion a which will yield inwardly when manual pressure is applied to the closure 35, thereby, through tube 39, applying pressure to the contents of the container, whereupon material from the container is expelled through tube 43. Also, as in previously described embodiments, the closure: 35 is provided with a flange 41 having a peripherally thickened rim 48 to accentuate the sealing effect, in cooperation with cap 36 and ring 31.
. In the several embodiments shown and described herein, the provision of the thickened portions l3, 2| and of closures Ill, 20 and 35, respectively, insures thatoutlets H, 32 and 44- will maintain a relatively constant directional position despite any usual, reasonably energetic flexure of the cap. The relatively more flexible area of. the closure, secured by localized thinning of the :wal l, ,cooperates to this same end and purpose.
