Claims.

-My invention relates to a closure device and has particular reference to a closable orifice device of the class employed for closing the opening in containers in such manner as to permit the withdrawal of the container contents and which finds particular utility when used with containers packaging viscous liquids.

Considerable difiiculty has in the past been experienced in pouring liquids from that class of containers having an opening in the top, particularly when the liquid was viscous as in the case of syrup, catsup, and the like. This difficulty arose primarily from the fact that it was virtually impossible to stop the pouring operation without dribbling the liquid down the side of the container, thus imparting a messy appearance thereto and making it impossible to handle the container 2. second time without getting previously spilled liquid on the hands. means for overcoming this difficulty a number of types of closable orifice devices have been proposed which employ a blade-like closure memher for closing the orifice and cutting off the flow therethrough cleanly to eliminate drips, and this invention is directed to an improved device of this class which overcomes the disadvantages found in present constructions.

In the present constructions a great number is expensive to construct and difficult to assemble and disassemble. The present devices are also deficient in that it is very difficult to keep them clean or to clean them after they have become dirty. Because of the relatively large number of parts employed and the attendant dlmculty of assembling and disassembling, it has been found to be a considerable task to take one of these devices apart, clean it, and reassemble it.

It is accordingly an object ofniy invention to overcome th disadvantages found in prior constructions by providing a closable orifice device which employs a minimum number of parts.

It is a further object of my invention to provide a closable orifice device which may be readily assembled and disassembled for cleaning purposes.

It is also an object of my invention to provide in a closable orifice device of the class employing a cap body having a slidable blade mounted therein a means for guiding the slid- As a of coacting parts isemployed so that the device ing-movement of the blade comprising a guide channel formed integrally with the cap body.

It is also an object of my invention to provide a device of the character set forth in the preceding paragraphs which includes a spring for holding the blade member in the closed position and in which the spring operates to maintain the parts in their assembled relationship.

It is a further object of my invention to provide a device of the character set forth in the preceding paragraphs which embodies features of construction permitting the blade and operator therefor to be inexpensively constructed by a di stamping operation and which permits the cap body to be inexpensively constructed by a molding operation.

It is a further object of my invention to provide in a device of the character set forth in the preceding paragraphs a means permitting attachment of the device to a great number of.

- Fig. 2 is a longitudinal vertical .section 11- lustrating 'the details of construction of the device of my invention and its relationship to a common form of container for liquids when installed thereon; I Y Fig. 3 is a view similar to Fig. 2 illustrating the manner in which the device of my invention is assembled and disassembled;

Fig. 4 is a fragmentary elevational view of the cap body portion illustrating the construc-, tion of the guiding and spring holding recesses;-

Fig. 5 is a perspective view illustrating the appearance and details of construction ofa handle member employed.

Referring to the drawing, I have illustrated in Fig. l the appearance of the preferred form of my invention. In this form a cap body I is provided with an extension portion 2 adapted to coact with the cap body I in guiding and supporting for slidable movement a blade member 3, slidable movement being imparted to the blade member 3 bymeans of an operator 4 which is pivotally supported upon the extension 2.

As illustrated in Figs. 2 and 3, the cap body I I is provided with an upwardly extending cylindrical recess 5 adapted to fit over the spout por- 1 tion 6 of a can I or the neck or similar part of a bottle or other liquid container. The cap I may be secured on the spout portion 6 by providing a number, preferably three, of inwardly 3 which is slidablysecured :nates at its outer end in extending projections or bosses 8 adapted to enact with a groove 9 ordinarily formed about the upper portion of the spout 6. The cap may be installed upon the spout 6 by forcing it downwardly thereover, springing the metallic spout 6 inwardly until the bosses 8 seat within the grooves. In case the'spout 6 or the top of a bottle is provided with threads, the cap may be secured thereto by engaging the bosses 8 with the threads and rotating the cap to move it downwardly thereover. The top or ceiling of the recess .5 is provided with an aperture I through which the liquid contents of the container 1 may be poured. The orifice l0 may be closed by means of the blade-like closure member to the upper surface of the cap I for movement between a closed position overlying the orifice ID, as illustrated in Fig. 1,.to an open position permitting discharge of the liquid contents through the orifice.

I have found that the blade member 3 may be conveniently mounted for slidable'movement by providing a slot-like recess transversely across the top of the cap I. the recess being provided with a width substantially equal .to the width of the bladelmember 3. The blade member 3 may be held within the slot I by providing overhanging ledge portions 2 which are preferably formed integrally with the body of the cap The blade member 3 is preferably constructed of very thin spring material having a slight curve along its length so that while the portion which is extended over the upper surface of the cap I.

is held in a substantially straight line by the overhanging flanges |2,.the rearward portion thereof will curve downwardly so as to provide an engagement between a transversely extending slot 3 formed in that end of the blade member 3 and an upstanding ear |4 formed on the handle member 4.

The handle member is preferably constructed along'the lines indicated in Figs. 2 and 5 and includes, in addition to the handle portion 4, a forwardly extending projection |5 which termi the aforementioned upstanding ear I4. The handle member also includes a downwardly extending bracket portion 6 which is provided at its lower end with a forwardly extending portion terminating in a cylindrical bearing member I 1. As illustrated in Fig. 2 the bearing member I1 is adapted to be received within a rectangular recess [8 formed in the under surface of the cap extension portion 2.

, It will be observed that should the handle a be pushed downwardly it will pivot about the bearing member I! so as to move from the position indicated in solid lines in Fig. 2 to a position such as that indicated by dotted lines in this figure. It will be observed that this movement of the handle 4 will cause a rearward movement of the ear I4 and through its engagement with the notch 3 in the blade member 3 cause sufficient retraction of the blade member to open the orifice III to permit discharge of the liquid contents of the container I.

Pouring of the contents of the container may be facilitated by providing also through the ceiling portion of the recess 5 an air vent i9 which is disposed in a position to register with a corresponding air vent provided in the blade member 3 when the blade member is retracted to an opened position.

I prefer to provide a spring 2| which coacts with the extension portion 2 of the cap and the handle 4 to return the handle to its uppermost position and move the blade member 3 to the closed position whenever pressure is removed from the handle so as to maintain the bladememher 3 in the closed position and prevent accidental discharge of the'container contents. The spring 2| is preferably of the coil-torsion variety and is received within a rectangular recess 22 formed in the rearward end of the extension portion 2. One end of. the coil spring may be received in a bore 23 provided in the inner surface which defines the recess 22 and the other end 23a of the spring is preferablydisposed in a position to engage the handle member 4 at substantially the junction between the horizontal portion i5 and the vertical portion I6 thereof.

The handle 4 may be held in an aligned posi-' tion and against lateral movement by providing a sloping slot or recess 24 in the upper surface of the extension portion 2 whichhas 'a width and is so disposed as to receive the horizontal extension portion l5 of the handle member 4. I also prefer to provide a pair of rearwardly extending flange members 25 and 26 which operate to define a vertical recess 21 having a width substantially equal to the width of the vertical portion I6 of the handle member 4 so that the en gagement between this portion and the recess 21 will also tend to prevent lateral movement of the handle 4 relative to the cap.

"I have illustrated in Fig. 3 the manner in which the structure just described may be assembled. In performing the assembly operation the spring -2| is placed within its recess 22, the one end of said spring being inserted in the bore .23 provided therefor. In order that the spring may be inserted withoutovercoming the tension thereof, I provide a vertically extending slot 28 which is centrally disposed so as to receive the other end 23a of the spring when the spring 2| is placed within its recess 22. Then the handle member 4 may be installed by placing the end of the horizontal extension l5 in the forward portion of its recess 24. The handle member 4 and the spring 2| will then occupy the positions illustrated in Fig. 3. The handle may then be moved downwardly so as to tension the spring 2| and move the. bearing member I! downwardly along the recess 21 and then rearwardly along the under side of the ular closed position as illustrated in Fig. 2. The

blade member 3 may. then be slid through the slot H and, by virtue of the resilience of the material employed, be lifted over the upstanding ear l4 until it has been moved into a position registering the slot I3 with this ear. silience of the blade member 3 will then operate to establish the proper engagement between the ear and this slot. It will be observed that the device may be disassembled as readily by reversing the above described operation.

It will be observed that the. novel device just described employs only three parts in addition to the molded cap member these parts being the blade member 3, the handle member 4, and the spring 2| therefor. Attention is called tothe fact that the construction illustrated eliminates the use of hinges and securing means for holding the parts in their relative positions, the spring 2| serving the dual function of automatically returning the blade member 3 to its closed posiextension portion 2 until it seats within its recess I8, at which time the The retion and holding the blade member, handle, and cap in their proper relative positions.

I have found that the handle member 4 and the blade member 3 may be readily and inexpensively constructed by a die stamping operation and that the employment. of a molded plastic for the cap member I and its integral extension 2 permits the formation of the various slots, recesses, flanges, and ledges to be accomplished in an inexpensive and simple manner.

While I have shown and described the preferred embodiment of my invention, I do not desire to be limited to any of the details of construction shown or described herein, except as defined in the appended claims.
