This invention relates to a container closure. The present application is a continuation-in-part of my co-pending application Serial No. 690,611

tions so that container cups of various kinds can be attached to the base or sealing portion.

Another object is to make all modifications of the device adaptable to be used with present forms of bottle-and jar caps.

Referring to the accompanying drawings: Fig. 1 is a jar, partly in vertical section into which my device, also partly in vertical section,

is fitted.

Fig. 2 is a perspective view of one form of my device shown by itself. Fig. 3 is another form. of my device in a like view.

Fig. 4 is an elevation of a jar lid in which my device is fitted.

Fig. 5 is a plan view of the subject of Fig. 4.

Fig. 6 is a view of a Jar and my device similar to Fig. 1 except that the jar cap and measuring cup are integral. Fig. 7 is a perspective view of the combination jar cap and measuring cup shown in Fig. 1, in inverted position, showing a pouring lip.

Fig. 8 and Fig. 9 are elevational and plan views of the combination cap and cup shown. in Fig. 6.

Fig. 10 is a sectional elevational view of a form of 'cup'and cap which may be attached to each other by a screw thread. The gasket shown on the right side of the figure may be omitted as on the left.

Fig. 11 is a view of a form adapted to measure powders and corresponds to Fig. 10. The cap is shown in section.

Figs. 12 and 13 are cross sectional and side elevational views respectively of an eye-cup form of container adapted to be affixed to the cap by a screw thread.

, Fig. 14 is a view similar to Fig. 6 but showing the cap and measuring cup made integral with the cup of thin, flexible, transparent material and the cap provided with threads on the internal surface of its flange for cooperation with the jar threads.

The invention comprises not only the molded article such as is shown in Figs. 2, 3, 12 and 13, but also its combination, integral or separable with a jar-or bottle cap, with or without a gasket, as is shown in Figs. 1, 4, 5, 6, 7, 8, 9, 10, 5 11 and 14.

Referring now to Figs 2 and 3, w is a cylindrical cup which is adapted to contain either liquids or solids. It is integral witha base 2! which is both thin and flexible. Either inside the cup 10 as in Fig. 2 or on the outside thereof as in Fig. 3 ,is a measuring scale 22 hearing either volumetric, gravimetric or arbitrary graduations. It may be molded into the cup at the time of manufacture.

The preferred material for the piece shown in 15 Figs. 2 and 3 is the cellulose acetate plastic known as Tenite made by the Eastman Chemical Company of Kingsport, Tenn. The transparent forms of thisplastic are the preferred ones since their flexibility is high and the contents of the cup can be conveniently observed thru them. Other plastics, notably the urea-formaldehyde, phenolformaldehyde, resorcin-formaldehyde and vinylite resins are also suitable. Celluloid or parafiined paper may even be used, likewise metal is permissible where no corrosion or solution would result.

In Fig. 1, 23 is a jar of the Mason type, N being the metal screw top thereof. Inverted in the screw top or cap is the cup 20, the base or flange 2i thereof being fitted closely against the inner surface thereof. It is to be observed that ample clearance exists between the cup 20 and the neck of the jar. A soft gasket 25 is placed over the flange 2i and around the cup 2|! and makes contactbetween these and the upper edge 26 of the jar neck. Figs. 4 and 5 show the proportional relations of the parts clearly. It is to be noted that the gasket 25 has a tight fit between the walls of the cap M and the walls of the cup Ill. Therefore, it is dificult to dislodge and consequently holds the cup 2t and flange 2i securely against dropping out should the entire assembly be inverted without the support of jar edge 26. As a suitable gasket material, cardboard, paper, cloth, vulcanized fiber, soft rubber or asbestos paper will serve depending upon the nature of the contents of the jar.

Referring now to Fig. 6, which corresponds to Fig. 1, the cup it and the cap it are made integral. A'push fit exists between the cap't i and the jar neck 265. As is shown in Figs. 7 and 9, the inside of the cap it is round to fit the jar neck 26 while the exterior is hexagonal to aflord a good grip. As Figs. 7, 8 and llshow, a pouring spout 21 may be formed into the cup '20 at its top edge. 'The integral form shown in Fig. 6

may be used with or without a gasket 25. For solid contents of the jar 23 no gasket is necessary since the large tapered bearing surface between the jar neck and the jar cap is sufllcient to prevent sifting. A bayonet lock may be substituted for the screw threads or the push fit. It is to be noted that the cap 24 has a flat top 28 which is adapted to act as a base when the assembly is in the position shown in Fig. 8. As will be seen from Fig. 7, the space 29 between the cup 20 and the cap 24 is adapted to act as a gutter or catch-all for any liquid or solid that maybe spilled while filling the cup 20 from the main container 29. That operation is of course accomplished either by taking the cup and cap assembly in one hand while pouring out the contents of the jar with the other or by setting the cup and cap down on its base on a flat surface and then pouring the contents of the main container into it.

Referring to Figs. 10 and 11, the cap 24 in these cases may be made with an externally threaded boss 30 or with an internally threaded depres-L- sion 3|. This allows the cup 20 to be made separable as shown, in which case it is provided respectively with an internally threaded hole 32 as in Fig. 10 or an externally threaded base 33 as in Fig. 11. The separable construction is advantageous in producing a cheaper product since different materials may be used for the cup and cap. The cup, as shown on the right hand side of Fig. 10 may have a. flange 2| or this may be omitted as shown on the left hand side. Separability has also the advantage of interchangeability of cups for the same cap. For instance the eye cup 33 shown in Figs. 12 and 13, also provided with a threaded hole can be attached to the cap 24 of Fig. 10 or the cup 20 of Fig. 11 which has a. flared edge to receive powders could also be provided with a threaded hole toflt a cap with a threaded boss or the eye cup could have an externally threaded base to fit the cap 24 as shown in Fig. 11.

It is to be understood that wherever jar caps have been described in this application, bottle caps can be substituted.

Wherever an integral combination is described in this specification, it is to be understood that it may be molded in plastics, particularly those mentioned.

I claim as my invention:

1. An integral combination comprising a jar cap, a depending flange thereon, internal threads on the flange thereof, a measuring cup depending from the inner head surface thereof and equi-distant from the flange, said cup being thin and flexible, the entire combination being molded of synthetic organic resin material and adapted to seal a jar by pressure of the inner head surface of the jar cap on the top edge of the jar.
