'2 Claims.

This invention relates to a simple and inexpensive closure for containers particularly useful in the cosmetic and pharmaceutical field, oi the ype in which a movable cap is permanently amxed to the container but is readily manipulable to open or close the orifices or slots through which the contents are dispensed. More. particularly, the invention is concerned with the type of closure in which means are provided to retain the cap yieldingly in predetermined positions. The type of closure with which the improvements are concerned is to be distinguished broadly from the socalled slip caps which are slidable on the neck to open or close the dispensing opening and which are widely used because of their inexpensive construction. Contrariwise, the improvements are to be likened broadly to a popular type of closure in which a slidable. shutter is mounted in the neck-shell of a container to control the dispensing opening. The improved closure offers substantially all of the advantages in use of such last-named device but by reason of its simpler construction is much less expensive to manufacture costing practically no more than the slip cap, the users objections to which are generally recognized.

A further object of the invention is to provide in closures of the character indicated a cap which is readily manipulable by one hand when the container itself is supported by that same hand thereby contributing greatly to the convenience in use, as is known.

In accordance with the invention, the neckshell is formed with a closure formed as a portion of a. sphere in which are provided the usual dispensing openings of any desired number, area, and shape, depending somewhat on the character oi the contents of the container. With this neckshell is nested a similar cap engaged with the neck-shell by means which permit it to be moved thereon so that openings formed in thecap may be brought into registry with one or more of the to be dispensed. A detent is embodied in the construction so as to maintain the cap yieldingly in at least one predetermined position with respect to the shell as, for instance, when the openings in the two members are out of registry. Reference is now to be had to the embodiments illustrated in the accompanying drawings wherein:

Figure 1 is a view in side elevation, parts being broken away, and showing a. hemispherical cap nested on a hemispherical shell and adapted to be rocked about diametrically opposed pivots, detents being provided to restrain the cap in position opened, respectively.

fixed pivots substantially on the equator of the nested hemispheres instead of, as in Figure 1,- somewhat below the equator.

Figure 5 is a view in plan of the closure shown in Figure 4 and indicating by contrast with Figure 2 diflerent forms of dispensing openings.

Figure 6 is a view in vertical section taken on the plane indicated by the line 6-6 of Figure 4 and looking in the direction of the arrows.

Figure 7 shows in side elevation a further modification differing essentially from that shown in Figure 1 only in that the walls of the nested hemisphere adjacent the pivot pins are flattened.

Figure 8 is a view in plan of the closure shown in Figure 7.

Figure 9 is a view in vertical section taken on the plane indicated by the line 9-9 of Figure 7 and looking in the direction of the arrows.

Figure 10 is a view in side elevation of a further modification in which the diametrically opposed pivot pins rest in a circumferential groove, 9. part of the cap being broken away to show the engage-' ment of a suitable detent with the groove.

Figure 11 is a view in plan of the closure shown in Figure 10, a part of the cap and shell being broken away to show the relation of a detent with the groove.

Figure 12 is a view in vertical section taken on the plane indicated by the line I 2-l2 of Figure 10 and looking in the direction of the arrows.

It is to be understood that the improved closure may be formed for attachment to containers of any type and of any material although, at the present time, the widest field of usefulness is oifered for association of the closure with tin, containers. As shown in Figures 1 and 3 the breast of a conventional tin container is indi- I cated at a and the improved neck-shell at I), this the particular requirements. In nested relation i to the hemispherical shell I: is an outer cap 0, the inner surface of which embraces snugly the outer surface of the hemispherical shell so as to give a contact closure of sufilcient tightness for commercial purposes. The contents of the container may be powder, paste or liquid. In the forms illustrated in Figures 1-3 the cap c is formed with downwardly extending lugs c' at diametrically opposed points, these lugs extending belowthe equator of the hemispherical cap. The lugs c' at opposite sides 01' the cap have punched therein dimples or nibs c, the convex exterior surfaces of which are received in dimples orrecesses' b punched in the shell b at diametrically opposite points. The engagement of the nibs c with the dimples 1) provides the cap with opposed fixed pivots about which the'cap may rock on the shell b. The cap 0. has formed thereon along its edge. extending away from the lugs c', horizontal flanges c which are not only sightly but aflord convenient finger pieces to facilitate rocking of the cap .about the pivots e in one direction or the other. In constructions where such members'as' the flanges c do not serve readily as stops to limit the rockn'g movement of the cap it is advisable to provide de tents so that such rocking movement of the cap will be checked when the dispensing openings 'are aligned. For instance, as shown in Figures 1-3, the cap may be provided with a, dimple 0" preferably at a point between one of the pivots c and the pole of the cap and this dimple will engage yieldingly any one of three juxtaposed cooperating.recesses-b stamped in the shell b. Engagement of the d mple c withthe middle recess b will hold the cap in its normal position with the flanges c substantially horizontal and at this time the openings 0 in the cap will be out of alignment with the openings b in the shell. When the capis rocked to the right as indicated by dotted lines in Figure 1 the detent c will be brought into engagement with the recess b which is placed at the right. Similarly, if the cap is rocked to the left as viewed inFigure 1, the detent 0 will be brought into engagement with the recess b at the left. Thus, when the cap is rocked to the right its openings 0 will be brought into registry with openings in the shell and ii the cap is rocked to the left from its normal position the open ngs 0 will be brought into alignment with other openings in the shell, the closure in either event being in condition for dispensing of the contents.

In Figures 4-6 a closure embodying the invention is shown as incorporated in a screw-cap d which, as will be understood, may be threaded onto the screw-.neckof a container. In thisform, as in the previous embodiment, there is provided a hemispherical neck-shell d which may be aflord'sa convenient finger piece to facilitate formed'integral with the screw top it and connected therewith by a neck d of any desired sightly configuration. The cap e is not provided with downwardly extending lugs but is formed with diametrically opposed dimples e' located substantially on the equator of the hemisphere and adapted to be received, as heretofore explained, in diametrically opposed recesses d? formed in the shell d. A dimple e is struck in the cap e for cooperation with a recess d in the shell to hold the cap in its median position wherein its dispensing slot e is out of registry with the slots (1 in the -.'shell. In this embodiment the flanges e by which the cap may be conveniently rocked on the pivots e are adaptedto engage the screwtop it when the cap is rocked to'.a sufiicient extent to bring the slot e into registry with one or the other of the slots d in the shell 11'. Since the flanges thus act aslimit stops it is unnecessary to provide additional detent means when the dispensing openings are aligned. The user, of course, need give no thought to their alignment since the cap will automatically be checked in its travel at the appointed place.

l The embodiment illustrated inFigures 7-9 is essentially similar to that shown in Figures l-3 except that the shell has'its sides I flattened in proximity to the diametrically opposed recesses which receive the pivot members g of the cap a. Similarly, the cap g has its side walls flattened as at g. in proximity to the pivot members g so as to nest snugly with the flattened walls of the shell I. The remainder of the construction is in all respects similar to that illustratedin Figures 1-3 and fully described hereinbefore. Flanges g on the cap facilitate its rocking movement to theright or left from its median position on the pivots g. A detent formed as a dimple in one of the flattened walls g of the cap may engage any one of three recesses f in the juxtaposed flattened wall I of. the shell, as heretofore described.

In the embodimentillustrated in Figures 10-12 the hemispherical shell I is formed with a circumferential groove 1' substantially at the equa-' tor. The cap m is formed with diametrically opposed nibs m constituting the pivot pins. In

this embodiment assembly of the cap on the shell is greatly facilitated because when it is pressed down into nested relation the nibs m spring into the groove 1 thereby retaining the cap on the shell and afiording a pivotal axis on which the cap may be rocked. It is evident that the angular relation of the cap to'the shell in this initial assembly, about the vertical axis, is

immaterial. To hold the cap in predetermined relation to the shell, that is to say, in what will be called its normal position with the flange m substantially horizontal, .a detent m of any suit-- able form may be pressed in the cap in proper relation to the groove 1 with which it cooperates. A similar detent 1n indicated in dotted lines in -Figure 10 may be provided at the other side of the cap in diametrically opposecl'relation to the,

detent m These detents are formed on an axis of the shell substantially at right angles to the axis of the pivot points m. The shell I may be formed with segmental openings 1 with which may align openings m in the cap when the cap is rocked on the pivots m, all 'asdescribed with reference to the embodiment illustrated in Fig-- ures 10 and 12. However, when the detents m m rest in the circumferential groove 1 the openings m in the cap are out of alignment with the openings 1 in the shell The circular flange m rocking. of the cap on its pivots m. This flange may serve as a stop to limit the rocking movement of the cap, through. its engagement with the breast n of the container,
