UNITED STATES SELF-CLOSING TOP AND DISPENSIN CONTAINER William F. rum, Passaic, 1., minor to (Jontinentai Can Company, Inc., New York, N. Y., a corporation of New York Application April 26, 1943, Serial No. 484,830

Claims. The invention relates generally to container structures employed in the packaging of pow- Figure 4 is a central vertical longitudinal sec-- v tion of the dispensing top per so with the slide dered granular or similar products which are to be poured or dispensed in limited quantities from the containers, and it primarily seeks to provide a novel top structure for containers of'the type stated wherein at least one pouring or dispensing opening is provided, and wherein is included a slide or gate structure for controlling s aid opening and displaceable by finger pressure for uncovering said opening, and means for automatically closing the opening when finger pressure is released.

An object of the invention is to provide a container top of the character stated in which is included a centrally disposed dispensing opening, a slide or gate structure having two dispensing openings therein one disposed at each side of the center of the slide or gate, and spring means constantly tending to' hold' the slide or gate centered with its openings out of registry with and at opposite sides of the top opening and its center portion over and closing the center opening, said slide or gate being displaceable by finger manipulation for bringing one or the other of its openings into registry with the top center opening and automatically returnable, upon release of finger pressure and by spring action, to its normal top center opening closing position.

Another object of the invention is to provide a container top of the character stated which is dome shaped or upwardly crested, in which the dispensing opening closure member slidably embraces and is pivotally mounted on the top and in which the spring means is in the form of a loop having its main body suspended, into the top through its top opening and its ends engaging the closure member through the center top open- I ing in a manner for constantly tending to hold the closure member centered over the top opening.

With the above and Other objects inview that "will hereinafter appear, the nature of the invenmoved to the right, as for dispensing powdered or granular products through the dispensing aperture at the left of the center of the top.

Figure 5 is a central'vertical longitudinal section of the dispensing top per se with the slide moved to the left, as for dispensing powdered or granular products through the dispensing aperture at the right of the center of the top.

Figure 6 is a detail plan view of the slide or gate centering spring per se.

The improved dispensing top includes a top body 5 which is dome shaped or crested. The top is half circular in vertical longitudinal cross section, the arc of curvature'being struck from the center 8 as illustrated in Figure 1. The top I is provided with'a central opening I in the manner Q clearly illustrated in Figures 1, 3, 4 and 5.

A slide or gate member 8 snugly fits over and is slidable on the top body '5, said slide or gate being curved to conform to the curvature of the external surface of the top in the manner clearly illustrated in Figures 1 and 2. The element 8 is provided with side wings 9 which closely embrace the sides of the body 5 and are pivoted as at it to the top body 5 so as to swingably mount the slide or gate 8 for slide swinging movement about i the center or axis 8.1

The slide or gate 8 is provided with oppositely directed finger engaging extensions Ii, and with a centrally disposed elevated portion i2 forming a space intervening the element 8 and the upper or external surface of the top body 5. The centrally elevated portion if of the slide element 8 is dimensioned to completely cover the central opening I in the top body 5 when the slide is in its normal, centered relation illustrated in Figures 1 and 2 of the drawing. The slide or gate member 8 is equipped with two dispensing openings, one thereof l3 being disposed at one side of the elevated portion I2 and the aperture 1,, and the other opening I 4 being disposed at the opposite side of said elevated portion and opening in the manner clearly illustrated in Figures 1 and 2.

A leaf spring I5 is provided and depends in the form of a loop in the top body 5 and through the central aperture I therein in the manner clearly illustrated in Figure 1. It will also be apparent by reference to said figure that the top openin 1 presents two end stop walls as indicated at the right and left in Figures 1, 4 and 5. When the slide is in its centered positionillustrated in Fi ure 1 the ends of the spring loop I! are disposed at points adjacent said top opening end walls. Thus one end oi the spring loop will be engageable with an end stop wall of the top openin and held against movement thereby as indicated in Figure 4, or in Figure 5, when the slide is moved in one direction or the other, and the other end will move with the slide in the manner indicated in said Figures 4 and 5. It will be observed by reierence to Figures 1, 2 and 6 that the spring element includes end enlargements It dimensioned to closely but movably fit in the top body opening I, and each enlargement l6 also is provided with lateral projections H which engage over the edgesof the top body defining its central opening 1 within the space formed beneath the elevated central portion I! of the slide or gate member 8.

At the lower portion thereof the top body 5 has its upright wall portions bent upon themselves to form a. bead or abutment shoulder l8. It will be observed by reference to Figures 4 and 5 of the drawing that a skirt portion l8 extends below the shoulder IS. The dispensing top illustrated per se in Figures 4 and 5 can be conveniently attached to any form of container structure in the manner clearly illustrated in Figure 1. In this illustration the top portion of the container is generally indicated at 20. In the attachment of the dispensing top to the container, the skirt I9 is inserted through a suitably shaped receiving opening and is then upset or flanged as at 2| so as to clamp the edge of the container defining the dispensing top receiving opening between the flange 2| and the abutment shoulder I8 in the manner clearly illustrated in Figure 1.

The normal position of the slide or gate on the dispensing top is illustrated in Figures 1 and 2 of r the drawing. Should it be desired to dispense powdered or granular material from the container, a person grasping the container in his hand would depress the finger piece I l at the right hand side of the figure in the manner illustrated in Figure 4, thereby bringing the left hand dispensing aperture I 3 into registry with the top body central opening l1, and then by suitably tilting the container the material could be dispensed through the registering openings I and I3. Should it be desired to dispense material through the right hand aperture I4, the tilting of the slide or gate 8 is reversed in :the manner illustrated in Figure 5. Regardless of the direction of movement of the gate or slide 8 for bringing the central aperture into registry with the left hand dispensing opening l3 or the right hand dispensing opening it, the movement results in a storing of ener y in the spring I5 by moving the ends thereof toward each other, one said end abutting an end of the aperture I and the other opposite end of the elevated portion l2 of the slide or gate 8. Obviously the spring will react to return the slide or gate to its centered, normal position illustrated in Figure 1 whenever an operator releases finger pressure from whichever one of the finger pieces H has been engaged to bringdispensing openings into registry.

It is of course to be understood that the details of structure and the arrangement of parts may be variously changed and modified without departing from the spirit and scope of the invention.
