as shown in Fig.-10. Ineithercase the shutter 15 isformed with an aperture `I6 which conforms in i size and shape to .the aperture 5 in the shell, and

outwardly extending nibs I8` and I9 are formed on opposite sides` ofthe aperture I6, the 1 nibs,` apertures fand, openings in both the `shell and the shutter-being so constructed and :arrangedthat when the shutter lsassembled Vwithin `the shell, the nibs It and I9 projectoutwardly through the openings `li and l, respectively, to `provide linger pieces by` means oflwhichthe shutter may be rocked rjslidso as tobrlngthe'apertures 5 and I6 into andout of register. i i In assembling the parts, the shutter is first positioned withinA the shell (preformed with -the enr--` ception `ofthe protuberances and lll) andlwhile the"shutter isgbeing held in position, the protuberancesa and I0 are then struckV inwardly by I, suitable dies, `thlls .Providing vflanges which slidably supportthe shutter within the shell.

" to 6,-except that the shutte'rJS is slidably sup- 50 portedbya bridge 25, (Figs. sans 9)` instead of inwardly struck protuberances. The bridge 25 consists of anarcuatemember conforming to the! iystruck protuberancess and l0"(Fig.3) which curvatureof the shutterland having upstanding i the shutter in position, as shown in Figs. 8 and 9. The bridge 25 may be secured within the shell in any suitable manner, as for 'example an interior-shoulder formed by an inwardly struck circumferential rib 26 in the skirt I2 of the shell.

In each of the above embodiments, the shutter I is shown, by way of illustration, as a cylindrical shaped member, but it is to be understood'that, if desired, the shutter may be in the form of a cylindrical segment or arc-like member I5', as shown in Fig. 10, in which case it may be secured in position in the same manner as shown in Figs. 1 to 9. If desired, headed pins, .rivets or the like members I0 may be used vas nger pieces in place of the integralnibs i8 and i9, particularly where the shutter is made of celluloid or other material which does not possess the capability of being easily worked.

It will be noted that a closure constructed in accordance with the present invention may be easily opened or closed by the thumb or ngers of the hand holding the container to which itY ls attached, and that the closure may be adjusted so as to regulate the ow of material through the aperture 5.

Instead of a single, comparatively large d ispensing orifice formed by apertures B and I6, a number of smaller dispensing holes may be provided, especially when the closure is to be used for ilnely pulverized materialssuch as toilet powders. .AV series of small holes in the shutter corresponding in arrangement to a series of small holes in the topshell would be brought into and out of register by rocking the shutter in the manner. already described, n

Although the closures abovev described are shown as forming the top of a rigid container C,

it is to be understood that their utility is not limited for use with containers holding powdered Vor granular material, as such closures may also be used with collapsible `tubes containing'tooth paste, grease and the like plastic or semi-fluid substances, andv hence the term container", as herein used, is intended to include collapsible tubes as well as the various having rigid Walls.

While I'have shown and described different desirable embodiments of the invention, it is to be understood that this disclosure is for the purpose oi' illustration, and that various changes in shape, proportion and arrangement oi' parts, as well as the substitutionof equivalent elements for those herein shown and described, may be made without departing lfrom the fspirit and scope oi' the invention as set forth inthe ap# pended claims.
