Pershall. Brcmerton, Washi, asslgnor to Sanicut Mfg. Port. Orchard, Wash, a

ashlngto corporation of W Application June}, 1937, Serial No. 146,091 1 My present invention relates to the .art of closure devicesand more particularly to a closure attachment for containers.

Considerable difficulty has been encountered in thepast in providing'a closure attachment for use with containers of syrup, honey, powders,

granular materials, and the like, which would An important object is the provision of means whereby the closure means eflects a clean cut-oil of any liquid and, particularly in the case of :3 viscous liquids, prevents any drip after the closure has moved to its closed position.

Another object of my present invention is to provide means whereby the increased pressure of a powerful spring is applied dire'ctlyto the i slide itself, and not to the smail downwardly bent end lug, as in my former construction.

A still further object of 'my present invention is to provide means for adequately venting. the

container so that when the discharge opening is k in use an air vent will be provided together with means that assure that the same will be maintained in operative condition at all times.

Another object of my present invention is to provide means whereby downward pressure is 35 applied to the extreme or closingend of, the slide member during the closing-operation.

Other and morespeciflc objects will be apparent from the following description'taken inconnection with the accompanying drawings, where-,

Referring to the drawings, throughout which like reference characters indicate like parts, I5 designates the main member or body of my dispenser unit. This may be formed of any suitable material. It may be die-pressed from sheet .material, oi '";it may be molded from any of the 7 {various materials that lends itself to pressure moldinguor, more preferably, it maybe made by die casting fromsuitable metal. Throughout the present drawings I have indicated the inner bore as being threaded at lfso that it may be screw fastened on to any suitable container. It will be apparent, it is believed, that any suitable means may be substituted for the thread shown; if the device were to be used on a straight can or lipped bottle this inner bore would of necessity have to conform to the outer surface-of the container. On one side the body member is provided with a spout portion [8, which for certain liquids is provided with a lip portion having inner wall' l9 and outer wall 20 disposed, substaiitially at right angles to cap" surface of the spout and, on its opposite side it is provided with 5 the extension 22 which serves to house the pivotally operated lever 24. This extension may continue on to form the integral handle ZS, or it may merely provide an anchor as at 28 for a separate handle 30 which may be secured to base 28 as bythe threaded stud 3|. Body 15 is further provided with the vent hole or opening 32 which provides a point of ingress forair during the dispensing operation. To assure that this vent will at all times remain open and in oper- I is best adapted when no handle proper is. used,.

ative order, I have provided a coacting, pointed lug 34 formed as part of lever 24 and adapted to substantially close opening 3 2 after the showing of Figure 8. This seals this'opening so that dust, insects, and the like, cannot enter when the device is closed, and on opening of the device a retraction of lug 34 assures that the vent will be cleared of any passable obstruction and open for the entrance of air.

In order to provide the maximum ease of cleaning I have provided that lever 24 have its downwardly extending pivot supporting portions as 36 and 31 joined as by webs 38 and 40. This provides a cavity as 4| in which one end of spring 42 rests. It will thus be apparent, it is believed, that a smooth surface is presented by wall 38 which will assist the housewife materially in keeping the device in most sanitary condition, and effectively prevent viscous liquid coating the coiled portion of spring 42 and thus produce an unsanitary condition which would not lend itself to ready cleaning. Lever 24 may be made in various forms to suit different conditions. One form, shown more generally in these drawings, has the short, thumb-engaging portion 44, or it may be extended with its position slightly altered after the showing of Figure 10, wherein leg portions 36 and 31 are reduced and the overall length of the member is increased. This particular form ofconstruction as shown in Figure 10 ther provided with abutting surfaces as 52 and 53 which are adapted to operatively engage the end portions of slide '50, as 55 and 56, disposed on each side of lug 48 so that in the closing operations the full force of spring 42 will be applied by surfaces 52 and 53 directly against the end of the slide 50 and thus a heavier spring can be used with no fear of damage to lug 48. This is of particular value when heavy viscous substances are used and especially where there is a tendency for crystallization.

Slide 50 is adapted to operate preferably within a depressed guideway 58 formed in the top of body l5 after the showing particularly of Figure 5. To positively hold slide 50 within guideway 58 I provide, near the mouth end of the guideway, the undercut retaining lugs 60 and 61. These may be formed either after the showing of Figure 4 as part of the body I5 or they may be provided as separate rivets after the showing of Figure 12. In either instance it is desirable that these lugs be'as close to the spout l8 as the contour of body I5 will permit. As illustrated in Figures 9 and 10, the end of lever 24 which bears lug opening 46 should be sufficiently far displaced, from a. vertical plane through pivot 64, that there will be a distinct lifting of slide 50 ofi guideway 58 "so that the friction in opening the device will be reduced to a minimum. During the closing operation this relationship functions to provide a secureengagement between the extreme end 66 of slide 50 and the upper surface of spout l8, When so constructed a very firm and close contact is provided that cleans the spout during each operation and assures a clean cut-off of the liquid being dispensed.

To further assure that there will be no drip after 'the slide has closed spout I8 I prefer that slide 50 be of such a size, and that the extreme end be struck with such a curve, that it will substantially overlap spout l8 on both edges and outer extremity, after the showings of Figures 1. 8, and 11. It has been found desirable that the outer corners as 61 and 88 be of such an extent that they will clear the extreme corners 10 and II of spout l8 before the slide leaves the extreme end of spout l8. This has been found to materially assist in providing a dripless closure. The most convenient manner yet devised to provide this relationship is to provide that the radius of end 66 be substantially greater than the radius of the end of spout l8. It would naturally follow that if spout l8 were angular the same rela-' tionship could be maintained.

Method of operation In using my device, after the container C has been filled with liquid, powder, or granules to be dispensed,. it will be found that the spring 42 will force the closure slide 50 toits closed position as indicated in Figures 1, 8, and 11. When it is desired to use the device pressure is applied to the thumb rest 44 of lever 24 and by depressing the same, slide 50 is withdrawn from its position of closing spout l8 after the showing of Figures 9, 10, and 13; when the desired amount of material has been dispensed the pressure can be removed from thumb-rest 44 and the spring 42 will tend to again seat lever 24 in its normal position, as shown in Figure 8., In so doing the force of spring 42 will be applied by abutment surfaces 52 and'53 to the extreme end of slide 50 by engagement with surfaces 55 and 56. .In

this manner a direct force is applied to the ends of the slide; and, evn though reasonably light material is used, considerable force can be applied with no danger of buckling the slide. In

, the final action of closing spout l8 the liquid is first wiped off the extreme corners I0 and II of 'the spout, and any liquid so removed will amal- I claim as new and desire to secure by Letters Patent is:
