JOSEPH J. GANNON, OF ST. CLAIR, MICHIGAN, ASSIGNOR TO DIAMOND CRYSTAL SALT COMPANY, OF ST. CLAIR, MICHIGAN, A CORPORATION OF MICHIGAN.

CLOSURE.

Application filed June 18, 1923.

To all whom it may concern.-

Be it ,known that I, Josnrr-r J. GANNON, a citizen of the United States of America, residing at St. Clair, in the county of St. Clair and State of Michigan, have invented certain new and useful Improvements in Closures, of which the following is a specifloat-ion, reference being had therein to the accompanying drawings.

This invention relates to closures for pouring apertures in containers, packages and the like.

An object of the invention is to provide the pouring aperture with a simple and efficient closure which, when in closed position, will maintain the container in substantially sealed condition so that the contents will not be spilled and which, when in open or partially opened position, will guide the flow of material in a predetermined direction and thus will prevent any lateral flow.

Another object is to provide a closure which may be easily and quickly applied to or removed from the container.

Another object is to provide a closure which may be readily adjusted in the pouring aperture and which will remain automatically in any adjusted position.

Another object is to provide a strong and durable construction which can be manufactured at a comparatively low cost.

With the above and other objects in view, the invention consists in certain novel features of construction as will be more fully described and particularly pointed out in the appended claim.

In the accompanying drawing Figure 1 is a perspective view of a container provided with the closure and showing the same in open position;

Figure 2 is a sectional View through the closure and adjacent portions of the cor. tainer showing the closure in closed position;

Figure 3 is a view similar to Figure 2 but showing the closure in open position;

Figure 4 is a detailed perspective view of the closure;

Figure 5 is an end view of the closure.

Referring now to the drawing in which like characters of reference designate corresponding parts throughout the several views, the numeral 1 designates a closure far a pouring aperture 2 which is preferably formed in the top 3 of a suitable container Serial No. 646,185.

l The aperture 2 is preferably of substantially rectangular form and is provided at its lnner end with an inwardly projecting tongue 5 which is separated by parallel slits g from the adjacent side portions of the The closure is preferably formed from one piece of material and is preferably provlded with a flat top 7 having parallel substantially triangular-shaped wings 8 extendlng downwardly from the side edges thereof. The inner end of the closure top 7 is preferably pivot-ally mounted on the tongue 5, while the outer end is preferably provided with an extension 9 that is adapted to rest upon the top of the container.

To detachably hold the inner end of the closure top in engagement with the tongue 5 while the closure is applied to the container, I preferably provide a pair of parallel tongues 10 which extend rearwardly from the rear ends of the wings 8 adjacent to the top 7 and which are preferably provided with straight upper edges 11 for engagement with the lower surface of the top of the container.

The upwardly swinging movement of the closure is preferably limited and for this purpose I preferably provide a pair of tongues or stops 12 which extend forwardly from the forward ends of the wings at the lower edges thereof and which are preferably provided with straight upper edges 1?) for engagement with the lower surface of the top of the container. The straight edges of the tongues 10 are preferably disposed in a plane parallel to the top of the container while the straight edges of the tongues 12 are preferably arranged at an angle to the top of the container.

The forward ends of the wings 8 are preferably curved as shown at 14 and the length of the wings, with respect to the pouring aperture in the container, is such that the curved ends of the wings are constantly in frictional engagement with the forward edges of the pouring aperture. With this arrangement the closure will remain in any adjusted position.

When it is desired to apply the closure to the container, the tongues 12 are inserted into the pouring aperture so that the aligned notches 15, formed in the forward ends of the wings immediately above the tongues 12, will be in alignment with the top. of the container. -The closure is thenmoved forward until the notches receive the outer edge 16 of the pouring aperture, whereupon the tongues 10 may then be moved downwardly through the slits 6 until the flat top of the closure abuts the tongue 5. The closure may then be moved rearwardly until the inner ends of the wings abut against the ends of the slits 6. The closure may then be lowered to closed position as illustrated in Figure 2.

To prevent the closure trombeing accidentally shaken out of the pouring aperture,-the sides of the'notches 15 are preterably arranged parallel to the topof the container. Thus, when the closure is raised, these notches will not be in alignment with the top of the container.

"To remove the closure from the. pouring aperture,- the top of the container is depressed slightly at the outer end of the pouringaperture so that the notches 15- will receive the outer: edge 16 of the pouring aperture, whereupon the closure may be moved forwardly to disengage the projections 10 from the slits 6. The closure may then be moved rearwardly to be'withdrawn entirely from the pouring aperture. 7

WVhile it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent,

I desire to have it understood that'I do not limit myself towhat is herein shown and described and that such changes may be re sorted to when desired, as fall within the scope of what is claimed.

l/Vhat I claim as my invention is The combination with a container having a rectangular opening in the Wall thereof and a projecting tongue in said opening separated by parallel slots from the ad jacent side portions of the wall, of a closure for said opening having a top'pivotally engaged with one end thereof and having parallel depending substantially triangular shaped side wings, pointed projectionsextending forwardly from said wingsand adapted to engage said container to 'limit the upward swinging movement of said closure, the lower edges of said projections being formed by the rounded upturnof the lower edges of said wings and the-upper edges of said projections being-disposed-at an angle to said-top, and notches inthe forward ends of said wings witlr'edges parallel to the top of said closure torapplying the closure to the container,-the lower edge otsaid notches being anangled continuation'ot the upper edges of said projections.

In testimony whereof I affix my signature.

JOSEPH J. GANNON.
