Application December 5, 1936, Serial No. 114,306

7 Claims.

This invention relates to container closures for bottles, cans and other containers or receptacles and has for its general object and purpose to provide certain improvements in a closure of this kind described in our co-pending application for Patent Ser. No. 94,554, filed August 6, 1936.

It is a more particular object of the invention to provide a cap member permanently applied to the neck of the container and having a dispensing opening, together with a rotatable closure mounted upon said cap and provided with an opening therein, to register with said dispensing opening in one position of the closure, and cam means acting upon rotation of the closure in one direction to impart a vertical movement to the closure and engage a part carried thereby within the opening of said cap and in tight sealing contact with the neck wall of the container.

In one embodiment of our invention, the rotatable closure member is provided with a depressed portion in the top wall thereof and a disk of compressible packing material secured thereto, said closure member having a skirt or iiange provided with an inwardly turned lug on its edge to cooperate with a cam surface on the bottle neck. In another embodiment of the device, the wall of the bottle neck may be provided with an upstanding lug adapted to exert a compressing pressure against the packing disk carried by the closure member to seal the dispensing opening of the cap.

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

In the drawings wherein we have shown several 40 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 one form of our invention, the several parts thereof being in disassembled relation,

Fig. 2 is a top plan view,

Fig. 3 is a vertical sectional View taken on the line 3 3 of Fig. 2, the closure member being in its open position,

Fig. 4 is a similar view, the closure member being shown in sealing position,

Fig. 5 is a perspective view similar to Fig. 1 illustrating a modied embodiment of the invention,l

Fig. 6 is a top plan View thereof,

Fig. '7 is a vertical sectional view taken on the line 'I--l of Fig. 6 with the closure member in its sealing position, and

Fig. 8 is a similar view, the closure member being shown in open position.

Referring in detail to the drawings and for the present more particularly to Figs. l to 4 thereof, 5 designates the body of the container having the outlet neck 6. It will be understood, as this description proceeds, that this container may be of various forms and may be constructed of glass, metal, ber or other materials.

The end opening of the container through which its contents are decanted is covered by a sealing disk 'l of cardboard or other suitable material having direct contact at its outer marginal portion upon the end edge of the container or neck wall 6. This disk, as herein shown, is provided with a line of perforations 8 terminating at each end upon the marginal edge of the disk and defining an area or section 9 thereof which may be thus easily broken and removed to provide a dispensing opening II) in said disk through which the contents of the container may be poured in suitable volume.

The disk 'l is enclosed within and permanently conned against the edge of the container wall by a sheet metal cap having a top portion II and a. cylindrical skirt portion I2. 'Ihe top portion Il of the cap is provided with an opening I3 the edge of which registers with the line of perforations 8 in the disk 1, and this opening, at the outer edge of the top II of said cap is continued downwardly in the skirt portion I2 thereof, as shown at I4, said vertical section I4 of the opening extending below the end edge of the container neck.

The construction as thus far described substantially corresponds to the disclosure of our pending application. In this case, however, the Wall of the bottle neck at its outlet end is thickcned to provide an external ange I5 thereon said flange at diametrically opposite points being provided with vertically extending grooves I6 in its outer surface adapted to receive internal beads vor ribs I'I formed on the wall of the skirt I2 of the cap member. Between the grooves I6, at one side of the container neck, the lower face of the iiange I5 is formed with a circumferentially extending cam surface I8 terminating at one of its ends in a stop shoulder I9.

The skirt I2 of the cap member has a lower edge portion 20 circumferentially curved correspondingly to the cam surface I8. When .the

Cil

cap member with the assembled sealing disk 'I is applied to the container neck, the ribs I1 engaging in grooves I6 serve to accurately locate the edge of the skirt I2 with respect to the cam surface I8. After such application of the cap this edge portion 20 is bent inwardly over and upon the cam surface I8, as indicated at 2|. The wall of the bottle neck at the inner side of the cam surface I8 is formed with the groove or channel 22, co-extensive in length with said cam surface, for a purpose which will hereinafter appear. The remaining lower edge portion of the skirt I2 is also flanged inwardly beneath the flange I5 of the container neck, as shown at 23, so that the metal cap member with the sealing disk 'I are thus permanently locked or secured upon the neck of the container.

The rotatable closure, superimposed upon the xed metal cap above described, also consists of a relatively thin sheet metal top wall 24 having the depending skirt which is preferably knurled so as to permit the same to be securely gripped and easily rotated. This top wall of the closure member is provided with a liner 26 of a suitable compressible material, said top wall having an opening 2'I therein extended downwardly into the skirt or flange 25 as shown at 28. The compressible disk 26 also has an edge portion thereof removed to provide the opening 29, corresponding substantially in shape with the openings Ill and I3, and registering with the opening 2'I in the wall 24 of the closure. Said wall and its liner sheet 26, are formed with a depression, indicated at 30, which substantially corresponds in form and dimensions with the opening I3 in the fixed metal cap and the opening in the sealing disk 1.

The closure member is initially assembled with its opening 21 in registering relation with the opening I3 in the cap member by means of the indentation 3| formed in the wall of the skirt 25, which is adapted to be engaged in one of the external grooves resulting from the formation of the ribs II on the skirt I2 of the cap member. At the same time, the downwardly projecting lug 32 on the lower edge of the skirt 25 is properly located at the high end of the cam surface I8 on the container neck. This lug is then bent inwardly upon the flange 2l of the cap member and its end edge projects upwardly into the groove 22 in the neck wall of the container, as clearly shown in Fig. 3 of the drawings. This cam lug is of suflicient width to thus render the bending thereof and its disengagement from the groove 22 exceedingly difcult, so that, for all practical purposes, it serves to effectually lock the rotatable closure member in its applied position upon the metal cap.

When the parts are first assembled as above described, the depressed portions of the top wall of the closure and its liner sheet are superposed on the top wall of the fixed metal cap and disposed at substantially a right angle to the opening I3 in said cap. Therefore the remaining portion of the top wall 24 of the closure and its liner sheet will be spaced above the top wall of the cap as shown in Fig. 3 of the drawings. 'Ihe rotatable closure member is releasably retained in this position by the engagement of the indentation 3I on its skirt or flange in the vertical groove of the cap member.

Assuming that the section 9 of the disk I has been broken out or removed, and a part of the contents of the container decanted through the registering openings 2.1 and I3 of the closure and cap members, the container may then be securely sealed by rotating the closure member through 90 degrees. As the lug 32 on the closure member rides downwardly upon the camflange 2I of the cap member, a compressing pressure is rst applied to the disk 26 carried by the closure member, and as this pressure increases the top wall 24 of said member is slightly flexed and forced upwardly. When the depressed portions 3|] are approximately in register with the opening I3 of the fixed metal cap, the top wall of the closure member resumes its normal condition, and said depressed portions 30 of the closure member and its liner sheet 26 are forced downwardly into the opening I3 in the top of the metal cap and the opening Il] of the disk 1. Thus as the lug 32 rides upon the lower portion of the cam face I8 and comes into contact with the stop shoulder I9 the depressed portion of the liner sheet 26 will be tightly compressed against the end face of the container neck wall at the opening I3 in the metal cap. Preferably, as in our prior application, the edges of the openings 8 in the disk 'I and I3 in the metal cap are inclined or beveled so as to facilitate a tight sealing contact of the depressed portion of the liner sheet 26 with the edges of said openings as well as with the end of the container neck. In this manner, a very effective sealing of the dispensing opening in the fixed metal cap is assured when the closure member is rotated to its closed position.

In Figures 5 to 8 inclusive we have illustrated a modified form of our invention in which instead of providing the closure member and its liner with the depressed portions 30, the neck wall of the container is formed with an upstanding lug 33. The sealing disk 'I in this case has the portion 9 removed therefrom to provide the opening I0 prior to the application of the disk to the end face of the container neck. Preferably, the end faces of the lug 33 are beveled, as indicated at 34, and the edges of the opening IU in the disk 1 and the opening I3 of the metal cap are correspondingly beveled so that when said disk and cap are applied and permanently secured to the container neck, the lug 33 is received within the outer end of the openings I0 and I3, and with the edges of said openings in tight sealing contact with the beveled faces 34 of said lug.

Otherwise, this modified construction is substantially the same as that previously described. In this instance however, the degree of inclination of the cam face I8 can be relatively slight, as the vertical movement of the closure member relative to the metal cap need not be very great. When said cap is rotated to move the opening 21 thereof out of register with the opening I3 said closure member is forced downwardly so that its compressible liner 26 is brought into tight sealing contact at its outer edge against the end face of the lug 33 on the neck wall of the container to thus effectively close the opening I3. As shown in Fig. 8, the inclination of the cam face I8 is such that when the closure member is rotated to open position, it will also move upwardly to a slight extent as the opening 29 of the line 26 registers with the opening I3.

From the foregoing d-escription taken in connection with the accompanying drawings it will be seen that we have devised a very simple and effective closure means for containers such as are used for vending liquors and other products. While the device is of relatively simple and inexpensive construction, it protects the consumer against fraudulent practices, while enabling the container to be easily and quickly opened or closed. Also, by the provision of an effective sealing means for the opening through the container cap, after the contents of the container have been partly consumed, protection of the said contents against contamination and possible leakage and waste thereof is obviated. It will also be noted that our device is of such construction that in pouring or decanting the liquid from the container, it will not contact with the metal parts of the cap or closure members.

We have illustrated the device in its application to a bottle or container of glass but it will be understood that with certain minor modifications our invention may also be advantageously used upon containers of metal or fibrous materials, and in which the cap member may be either a separate element or integrally formed with the outlet neck of the container. Further, while we have disclosed several simple and practical ernbodiments of our present invention, it is to be understood that the essential features thereof may be susceptible to various changes in the form, proportions and detail arrangement of the several parts and we accordingly reserve the privilege of adopting all such legitimate variations thereof as may be fairly comprehended within the spirit and scope of our invention as claimed.
