Jean E. Masbach, New York, and Anthony F. Driscoll, Middle Village, Long Island, N. Y.

Application August 6, 1936, Serial No. 94,554

for bottles, cans and other containers or receptacles, and has for its primary object and purpose to provide a simply constructed device of this kind embodying means which affords a liquid tight seal for the container before and after it has been opened by the purchaser.

It is another object of the invention to provide a dispensing closure particularly designed for application to bottles or other containers of glass and which is so constructed that in dispensing the contents of the container, such contents will not contact with the metal parts of the closure.

An additional object of the invention resides in the provision of a dispensing closure which will effectually prevent the refilling of the container and the marketing of a substituted product therein without detection.

With the above and other objects in view, the invention consists in the improved dispensing closure and in the form, construction and relative arrangement of its several parts, as will hereinafter be more fully described, illustrated in the accompanying drawing and subsequently incorporated in the subjoined claims.

In the drawing, wherein we have shown one simple and practical embodiment of the invention and in which similar reference characters designate corresponding parts throughout the several views:

Fig. 1 is a perspective view showing the several parts of the device in disassembled relation.

Fig. 2 is a side elevation partly in section.

Fig. 3 is a top plan view showing the closure 35 in open position and also illustrating the removed section of the sealing disk.

Fig. 4 is a vertical sectional view taken on the line 4-4 of Fig. 3.

Fig. 5 is a similar view showing the adjustable 40 closure in position to seal the outlet opening in the sealing disk.

Fig. 6 is a detail sectional view taken on the line 6-6 of Fig. 5, and

Fig. 7 is a. plan view, the adjustable closure every case, the end opening of the container through which its contents are decanted, is preferably covered by a sealing disk 5 of cardboard, fiber or other suitable material having direct contact at its outer marginal portion upon the end edge of the container wall. As herein shown, this disk is provided with a line of perforations 6, terminating at each end upon the marginal edge of the disk, and defining an area or section 1 thereof which may thus be easily broken out and removed, to thereby provide a dispensing opening 8 in said disk through which the contents of the container may be poured in suitable volume.

The sealing disk 5 is inclosed within, and permanently confined against the end edge of the container wall, by a cap of sheet metal having a top portion 9 and a cylindrical skirt portion Ill. The top portion 9 of the cap is provided with the opening II, the edge of which registers With the line of perforations 6 in the disk 5, and this opening, at the outer edge of the top 9 of said cap, is continued downwardly in the skirt portion ID thereof, as shown at 12, said vertically extending section l2 of said opening continuing downwardly below the end edge of the bottle neck.

Preferably, the line of perforation 6 extends transversely through the disk 5 at an oblique angle, and if desired, the disk material may be partially cut through from one side thereof, at such an oblique angle, so that when the part 1 is broken out, the edge of the resulting opening 8 will be beveled or inclined in the manner clearly shown in Fig. 6. The edge of the opening II in the top wall 9 of the cap member is similarly beveled for a purpose which will be hereinafter explained.

The skirt portion H] of the metal cap may be permanently fixed or secured to the wall of the container or bottle neck in various ways. In the present instance, we have shown the neck of the bottle as being formed with a rib l3 upon its external surface, at a suitable distance below the end of the bottle neck. This rib, at one or more points, may be interrupted to provide a notch or recess indicated at I4. Thus, in applying the sealing disk and the metal cap to the neck of the bottle, by means of suitable dies, the

skirt portion thereof is tightly compressed upon the rib l3 and into the notch or notches I4 to thereby permanently lock said cap to the bottle neck against either longitudinal or rotative movement with respect thereto.

Also, if desired, the inner surface of the cylindrical wall of the cap may be coated with a suitable liquid cement.

Immediately above the rib l3, the outer surface of the bottle neck is outwardly beveled or inclined from the base of said rib, thereby providing a. similarly beveled or inclined annular section [5 of the skirt ill of said fixed metal cap.

A rotatable closure is superimposed upon the.

fixed metal cap above described, and also consists of a relatively thin sheet metal top wall [6 having the depending annular flange or skirt portion ll, the edge of which is inwardly inclined as at Hi to snugly contact with the inclined part I5 of the fixed metal cap, and thereby permanently hold the closure member in assembled relation with said fixed cap while permitting of its relative rotation. The top wall 16 of this adjustable closure member is provided with a thin liner sheet H) of fiber, paper or other suitable material, said wall and the liner sheet having an opening indicated at 2!! therethrough, and said opening in the closure member being extended downwardly into its skirt portion H as indicated at 2|. This opening composed of the sections 25 and 2| in the adjustable closure member sub stantially corresponds in form and dimensions with the opening Hl2 in the fixed metal cap.

In diametrically opposed relation to the opening 20 in the top wall I6 of the adjustable closure member, said wall and its lining sheet l8 are depressed as indicated at 22, such depressed part of the closure member substantially conforming in shape to the opening H in the top wall of the fixed metal cap and the opening 8 in the sealing disk 5. The marginal edges of said depressed part 22 of the closure member are also obliquely inclined at substantially the same angle as the edges of the openings 8 and l I so that, as shown at 23 in Fig. 6 of the drawing, when said closure member is turned or rotated from the position of Fig. 5, the depressed part 22 thereof will easily ride over the inclined edge of the fixed metal cap and upon the top surface thereof.

When the bottle or container is initially filled by the manufacturer, and the sealing disk 5 and metal cap member fixed thereto as above explained, the open end of the container is thereby tightly sealed against the escape of its contents. The adjustable closure member 56 is then applied, approximately in the position shown in Fig. i of the drawing. The top wall of this member being of thin flexible sheet metal, the part having the opening 20 therein will be displaced from its normal position into the arcuate form illustrated, while the depressed portion 22 extends in parallel relation to the top wall 9 of the fixed metal cap with its liner sheet [9 in contact therewith.

In order to dispense the contents of the bottle or container, the rotatable closure member is first adjusted to register the opening Qt-Zi thereof with the opening H-l2 of the fixed metal cap. The section I of the sealing disk 5 is then broken out as indicated in Fig. 3. When the contents of the bottle are now poured through the opening 8 of the sealing disk, it will fiow over the exposed end edge of the glass wall of the bottle neck, through said opening and substantially without contacting with any of the metal parts of the fixed cap or the adjustable closure member [6. When a part only of the contents of the bottle or container is dispensed therefrom, the outlet opening 8 through the disk 5 may be tightly sealed by adjusting or rotating the closure member 16 on the fixed metal cap from the position shown in Fig. 4, until the depressed part 22 thereof registers with the opening I l. Then, due to the inherent resiliency of the top wall of the closure member, the arcuately curved section thereof returns to its normal position and the depressed section 22 enters the opening H while the liner sheet 19 is urged tightly upon the end edge of the wall of the bottle neck at the outer side of the opening 8, thus sealing said opening against the escape of the contents of the container.

When the closure member I6 is rotated from the position of Fig. 5 and the depressed part 22 thereof rides over the inclined edge of the opening II and upon the upper surface of the fixed metal cap, the skirt portion ['5 of said closure member at the outer side of said depression will have a slight upward movement. The edge [8 thereof riding upon the inclined part I5 of the fixed metal cap member tends to position said skirt portion H at one side of the rotatable closure at a slight angle, thereby placing the same under tension. This action operates to frictionally hold the adjustable closure member against further casual rotation from the open adjusted position thereof as shown in Fig. 4 of the drawing.

Preferably, the outer surface of the flange or skirt portion ll of the closure member is knurled so that it may be securely grasped and easily turned or rotated.

In Fig. '7 of the drawing, we have illustrated an embodiment of the device particularly adapted for application to mustard or pickle jars or similar containers in connection with which a spoon or other implement is used. sealing disk 5 is provided with a slot 24 concentric with its periphery and terminating at one of its ends on one side of the line of perforation 6 in said sealing disk. The wall 9 has a similar slot 24, registering with the slot 24 and come municating with the opening ll. Thus, it will be understood that when the part I of the disk is broken outand removed, the slot 24 accommodates the handle or shank of the spoon or other implement when the closure member I6 is turned or rotated to its closed position. When the part 22 of the closure member is disposed in the position of Fig. 5, the spoon handle will be located in the closed end of slot 24 and project upwardly through the opening 20 in the closure member I 6.

From the foregoing description, considered in connection with the accompanying drawing, the construction, manner of use and several advantages of our improved dispensing closure will be clearly and fully understood. It will be seen that the device consists of very simply constructe ed parts which may be readily assembled and applied to containers of various kinds. Obviously, by means of such a device, a spurious product cannot be vended in the original container without detection, since in order to dispense the original product from the container, it is necessary to first break out the part I of the sealing disk 5. As this disk and the metal cap are permanently secured to the wall of the container or bottle, the fact that the original contents have been removed and the spurious product substituted, would be instantly detected by mutilation of the disk 5 resulting from the removal of the part 1 thereof.

Since the depressed part 22 of the rotatable closure member reseals the opening 8 in the disk 5 after the contents of the container have been partially dispensed therefrom, the remainder of said contents will be protected against possible In such case, the

contamination and leakage thereof prevented in case the container may be accidentally upset. Also, since by reason of our invention, the liquid as it is dispensed from the container does not contact with the metal parts of the closure, the possible deleterious effect upon the taste of the beverage or liquid is obviated. Of course, it will be apparent that in the application of our invention to various different kinds and shapes of containers such as are used in vending different commodities, numerous detail variations in the construction of the several parts may be required. Such changes may be readily made without substantially departing from the essential principles or sacrificing any of the advantages of our invention.

Accordingly, it is to be understood, that in the further development of our present invention, we reserve the privilege of resorting to all such legitimate changes in the form, proportions and relative arrangement of the several parts thereof, as may be fairly incorporated within the spirit and scope of the invention as claimed.
