This invention relates to dispensin closures for containers, such as v are. usually; provided for products. like spices, condiments; dentifrice. DQW: ders; cosmetic powders, medicinalpowders p is and tablets; The closure; as. hereinv described is adapted for use with. containers made of: l ss; tin, fiber and the like.

An objectiofmy inventiomisto provide a dis? pensing. closure which may be readily. and easily applied to and removed from a. container:.

Another objector: the invention. is l to. provide a dispensing closure which williproducean. efli cient original seal.

Another object of; the. invention. is toL provide a dispensing closure having; a portion, which is removable to uncoverropening-s fondispensing;-and which is easily replaceable to. reeestablish, an effective and efiicient seal.

Another object of the invention isato provide a dispensing closure havin a portion which is rotatable to uncover openings for dispensing and easilyrotatable to re-establish an effective. and eflicient seal;

Other objects of the-invention will 'appear-here.- inafter.

Basically; th dispensing closure, herein. described; comprises a cylindrical wall adapted to fit oven the neck of a container, a perforated transverse wall spaced intermediate the top and bottom of the cylindrical Wall, and: a cover piece in the form of an insert adaptedto fit. in the upper portion of thecylindrical wall and thereby coverand seal the perforations inthe transverse wall. This insert may beeasily displaced to uncover the perforations;

Fig; 1-6 is a. partrsectionalelevational; viewof the modified form: of? closure Shown in, Fig. 15 and thecontainer to which it..is;applied.

As shown inx Fig. 1",, theiclosure l0 consists: of acoverl: l; and; abody portion; I 2 made of flexible thermoplastic. molding compound such. as; polyethylene, or other-material having similar, physical properties; Thezclpsure is.adapted to beused with. a container I42 as-..herei-nafter described.

The body: portion. I2" comprises: a. cylindrical wall l5:and-' a diaphragm lfispaced intermediate the top and bottom.- of the cylindrical" wall I5; The inner surface of; the. lower part H? of the cylindrical walk is: shaped to maintain sealing contact with thesidesealing surface l8 of" the container necle I3 (Fig. 3). includes a flat circular plate 22, a: rim [9 ofiset downwardly therefrom, and a vertical annular wall 2] at the periphery of thecircular plate, connecting the plate 22 to the rim N! (Fig. 2). The rim, I9'i sp0sitioned to make sealing contact with the, top, 20' of the container neck I3. The plate. 22' is formed with perforations 23 asshown in Eig s. 1" and}; The upper part 25 of the cylindrical; Wall I5 is formed' with an annular bead 24' on its inner surface.

The. periphery of the cover It is formed with a .v.er.,tical. surface 26 (Fig.5) anda bevelled surface 21, The maximumdiameter. of the bevelled surface 21. isgreater than the diameter of the vertical surface 26. thereby forming a projecting lip, 30. The innerportion of they cover is cut away leaving an. inner wall. 28 concentric with the,- bevelled surface 21.

Asshown in Big. 3, whenthe. cover is snapped into the, top -o f the;body portion. the inner Wall .8.: over the; vertical wall 2; and the bottom 29 of; the cover; seals tightly; against the top of theg circular: plate- 22. The projecting lip 30 s-na-pszinto position below the annular-bead 24 and insures the; maintenance; of the seal.

Th'e bodynportion isprovided with a. notch 31 adaptedto:receive:a portionof a Web 32 connecting: the cover I If and. body. portion l2, and with a notch 33 adapted to. receive atab 34:. on the cover li (Figs; 2 and-3).

It should be-noted that all: the'elements. ofr'the The diaphragm 1-6 closure are so designed that the entire closure may be molded in one piece.

After the closure has been molded, the closure may be shipped to the packer in the condition shown in Fig. 2 or the closure may be shipped with the cover snapped into position. The latter is preferable since less shipping space is required and since the chances of severing the web connecting the cover and body portion are diminished.

After the container has been filled and it is desired to seal the container, the closure is snapped onto the neck of the container as shown in Figs. 3 and 4. Since a very good seal has been previously obtained between the cover and the body portion, a highly satisfactory package is obtained.

After the package reaches the consumer and it is desired to dispense some of the contents,

the consumer need only lift the cover by the tab 34, expose the circular plate 22, and dispense the amount desired. The cover H meanwhile remains-connected to the package by the web 32. After the desired amount has been dispensed, the

package may be rescaled by pushing the cover back into place. The reseal obtained will be equally as efficient as the original seal.

A modified form of the invention is shown in Figs. 6, 7 and 8. In this form of the invention, the diaphragm 16 of the body portion (Fig. 2) has been modified and as shown in Fig. 8 as [6, comprises a fiat perforated disk entirely in one plane. The cover I I comprises a disk adapted to make sealing contact with the upper surface of the diaphragm I6. I l is formed in the same manner as that of the cover I i in the other form of my invention.

The web 32 and corresponding notch 3| (Fig. 2) have been omitted in the modified form (Fig. 8). two forms of the invention in that the cover ll snaps into position providing a sealing contact between the surfaces of the diaphragm I6 and the disk 35. A comparison of these two forms of my invention is most readily apparent by a study of Figs. 3 and 8.

. Another modified form of my invention is shown in Figs. 9 and 10. In this form, the cover 31 is provided with a corrugated lip 38 which overlies the upper part of the cylindrical wall.

This lip may be grasped at any point to lift the insert. This modified form operates in other respects in the same manner as the closure in Figs. 6, 7 and 8.

Another modified form of my invention is shown in Figs. 11, 1c, 13 and 14. In this form, the

cylindrical wall 40 is provided with a disk 4| intermediate the top and bottom. This disk has an opening 42 as shown in Figs. 11 and 12. The cover 43 is flat and adapted to fit into the upper part of the body in the same manner as in the other forms of my invention. The periphery of the insert 43 is formed with a projecting edge 49 which is adapted to snap below the annular bead 24 and maintain the insert in position. The cover is also formed with an elongated opening 44 which is preferably of the same size and shape as the opening 42 in the disk 4!. The upper surface of the cover 43 is flush with the top of the cylindrical wall and is provided with an elongated knob or handle 45 which may be dished (Fig. 13) and is easily grasped to rotate the insert and bring the openings into register when it is desired to dispense the contents of the container. The cover may be rotated to bring the openings par- The periphery of the cover The method of scaling is identical in these tially into register as shown in Fig. 12, or entirely into register. Due to the peculiar physical properties of polyethylene, a very effective seal is provided and at the same time, the cover is easily rotatable to uncover or cover the openings.

Another modified form of my invention is shown in Figs. 15 and 16. In this form of the invention, the cylindrical wall 40 and disk 41 are identical with those shown in Figs. 11, 12, 13, and 14. The cover 43' is formed with a projecting portion 46 extending over the top surface of the cylindrical wall and with corrugations 41. The cover is formed with a dispensing opening 48. When it is desired to dispense the contents, the cover may be grasped and rotated to bring the openings into register.

Modifications may be resorted to within the spirit and scope of my invention.
