having means'to embrace said sealing disc so as to maintain the same in central or axial] aligned relation to the container mouth, whereby to hold the same at all times against displacement from registering relation to the container mouth.

Another object of this invention is to provide a 1 novel container of the dispensing type having a closure cap of the kind described wherein the sealing disc retaining means comprises a plurality of guard tongues or lugs spaced around the periphery of the sealing disc, said tongues or lugs being struck out of the cap top wall so that the resultant apertures left therein provide discharge ports through which, when the cap is loosened with consequent loosening of the sealing disc relative to the container mouth, the content of the container may be discharged.

A still further object of this invention is to provide a dispensing container wherein the closure cap is threaded to the container body so that it may be rotatively loosened to release the sealing disc for content discharge, and wherein a stop band of novel "character is afllxed to the container body for cooperation with a stop tongue with which the cap is provided, whereby the loosening movement of the cap may be desirably limited; said stop band optionally including means to visibly indicate the tightened and varitures of this invention, saidcap being shown in container closing and sealing condition; Fig. 2 is a vertical longitudinal sectional view, taken on line 2-2 in Fig. 1; Fig. 3 is a top plan view I container content, parts being broken away to show internal structure; and Fig. 5 is a transverse sectional view, taken on line i5 in Fig. 1.

Fig. 6 is a vertical longitudinal sectional view or a modified form of the container and closure Similar characters of reference are employed in is illustratively shown in the formof a glass bottle or Jar, but it will be understood that the same may alternatively comprise a can box or other receptacle form which may be made of metal, paper, plastics or any other suitable material.

- In the illustrated iorm thereof, the container i0 is provided at its upper end with a neck portion ll having external screw threads l2 formed thereon. Said neck portion ll terminates in an upstanding mouth defining portion or flange 13 of reduced diameter, the rim ll of which serves as a seat-to receive a sealing disc l5, which is adapted to bridge over and thus close and seal the open mouth It defined by said flange II.

The reference character l1 indicates the top wall of a closure cap, the skirt it of which'is provided with screw threads l8, whereby the cap may be threaded onto the container neck portion ll.

The sealing disc i5 is of diametric dimension somewhat larger than the external diameter of l 'the closure cap, and securely retained against any possibility of shifting displacement from a plurality of circumferentially spaced guard tongues or lugs 20 are struck out of and downwardly from the cap top wall l1, so as to depend therefrom around the periphery of the sealing disc it, thus providing a keeper cage 'i'or holding the latter in place. When the container is employed as a dispensing container, the apertures such aligned position in register with said mouth,

.loosened to permit 2|, which are formed in the cap top wall 11 by the striking out of said guard tongues or lugs therefrom, will serve as discharge ports through which the fluent content of the container may be sprinkled when the cap and the sealing disc are outflow of said content through the container mouth l6.

When the container is employed for dispensing a spot-cleaning fluid therefrom, it is desirable to provide the closure cap with an applicator member. Such applicator member usually consists in a pervious material, fabric or the like. Preferably a pile textile fabric is used, such e. g. as a mohair fabric. An applicator member 22 is shown applied to and over the top wall ll of the cap so as to overlie the discharge ports or apertures 2 I. The marginal portions 23 of said applicator member are folded down around the skirt of the cap and suitably secured thereto, as e. g. by an encircling anchor or binder wire 24. When so fastening the applicator member 22 to the cap, it is preferable to provide the skirt portion 18 of the latter with an indented annular seating channel or groove 25 to receive the binder wire and the marginal portion 23 of the applicator member embraced thereby, so that accidental displacement of the applicator member from operative assembled relation to the cap is prevented. It will be understood, however, that the applicator member may be secured to the cap in any other manner known to the art; or the same may be secured to the cap and container in the novel manner disclosed in my copending application for U. S. Letters Patent Ser. No. 330,820, flled April 22, 1940.

To seal the container against outflow of content therefrom, or loss of said content by evaporation or similar causes, the cap is rotated in one direction (e. g. from right to left as shown in Fig. 1), whereby the cap is screwed down the container neck portion ll so that the sealing disc I! will be forced down upon the rim ll of the container mouth defining flange l3 in closing and sealing relation to the container mouth It (see Fig. 2). On the other hand, if the cap is rotatively manipulated, in the opposite direction (1. e. from left to right as shown in Fig. l), the cap will be caused to rise on the container neck portion I I, so that the sealing disc will be released or freed so as to be capable of moving outwardly away from the container mouth l6 when the container is inverted (see Fig. 4), and consequently the fluid is permitted to flow outwardly through the container mouth around the sealing disc and into the cap interior so as to discharge through the apertures or ports 2|, and thereupon into the applicator member 22, when such element is employed, thus saturating the latter ready for use for scrubbing material to be cleaned with the fluid carried thereby.

In a dispensing container capable of being opened and closed at will in the manner described, it is desirable to provide means which will limit the rotative loosening movement of the cap, such meansoptionally including means to visibly indicate the closed and variously loosened conditions of the cap. A novel 'speciflc means for this purpose, which is independent of the containerper se, but which may be fixedly applied thereto in proper adjusted position for cooperation with the cap, comprises, a band 25 of sheet metal or other suitable material adapted to be applied to the container neck portion H in encircling relation thereto below the closure cap. This band 26 is frictionally or otherwise flrmly bound to the container neck portion against slipping displacement from an applied adjusted position thereof. If desired the meeting end portions of the band 28 may be joined by interengaging male and female coupling means 21. Formed in suitable manner in connection with the band 26 is at least one stop projection 28, which is adapted to cooperate with a flnger 29 carried by the cap so as to limit rotative loosening movement of the cap. A similar stop projection 23' may be provided to cooperate with the cap finger 29 at or near the limit of cap closing and sealing movement, although this is not essential. The cap finger 29 may terminate at its free end in a pointer portion 30 adapted to cooperate with indicia suitably inscribed on the band 26 to denote closed and various degrees of open condition of the cap (as shown more'especially in Figs. 1 and 4).

Referring to Fig. 6 of the drawing, there is shown therein, a simplified form of closure cap 3| of the kind adapted for sliding or telescopic application to the container neck portion, but

.wherein the dependent guard tongues or lugs 32 are provided for retaining a loose sealing disc 33 in register with the container mouth portion 34. Since this type of closure cap may wholly be removed from the container neck portion, the terminal portions of the guard tongues or lugs 32 may be in-turned to provide stop-projections 35 for preventing escape of the sealing disc 33 from the embrace of said tongues or lugs 32.

Since various changes in and widely diflerent' embodiments of the features of this invention could be made without departing from the scope thereof as deflned in the following claims, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.
