This invention relates to an applicator in the nature of an attachment for use in association with conventional collapsible tubes such as are employed at the present time for t containing and dispensing tooth paste, shaving cream, and analogous cosmetics and pharmaceutical preparations.

Thus specifically, as set forth, the inventive conception comprehends an attachment it} which is characterized primarily by a retaining frame, a delivery nozzle, and an applicator in the form of a brush, the arrangement and assembly being such as to connect the brush with the discharge neck of the tube in such a way as to permit contents of tube to be squeezed into the bristles of the brush for convenient usage.

Other objects, features and advantages will become more readily apparent from the fi 'following description and drawings.

In the drawings:

Figure 1 is an elevational view of the complete assembly showing the attachment in operative position on a conventional tube.

Figure 2 is a longitudinal sectional view on the line 2-2 of Figure 1. I Figure 3 is a perspective view of the retention or holding frame.

Figure 4 is a perspective-view showing the grouped relationship of the brush, nozzle and discharge end of the collapsible tube.

Figure 5 is a cross section on the line 5-5 of Figure 1.

Figure 6 is a fragmentary detail view of the lower portion of the lower section of the frame.

In the drawings the collapsible tube is designated by the numeral 7. This is of conventional construction and includes a screw threaded attaching and delivery neck 8. The applicator is here shown in the form of a brush generally represented by the numeral 9. The back of the brush is indicated at 10, the bristles at 11. Formed in the back of 4b. the brush is a keeper groove 12 which has a port in communication therewith leading to the bristles of the brush as shown in Figure 2. This groove is designed to receive the reduced tubular portion 13 of the delivery nozzle 14. This nozzle has a large end por- I A Application filed September 13, 1930, Serial No. 481,772.

-' The retaining or attaching frame designated generally by the numeral 18 comprises a pair of companion sections, the upper one of which is distinguished by the numeral 19 the lower one by the numeral20. Both of these sections are of general usage, configuration and form, and as resilientstrap metal. The lower section 'has its arm portion formed with outwardly pressed beads 21 which function as keys. The outwardly pressed portions 22 constitute reinforcing elements and the portions 23 indicate flat Webs which rest in contact with the adjacent side portions of the collapsible tube 7. This section 20 forms a sort of a saddle or stirrup in which the bendable or rollable end of the tube is seated. The upper section 19 has its arm portion formed with outwardly pressed beads or ribs 24 which define a keyway for slidable frictional reception of the aforesaid key 21. The- features 21 and 24 cooperate in forming a telescopic frictional connection between the companion sections 19 and 20. The intermediate portions of the arms. of the section 20 are bent inwardly or curved as indicated at 25 toform what may be designated as keepers over which the aws of the clamp 17 engage as shown in Figure 1. The relatively narrow portion 26 constitutes a holder for the brush element 9. 'It embraces a portion of the back 10 as shown in Figure 1.

In practice the nozzlel4 is engaged to the neck 8. The terminal discharge end 16 thereof is fitted into the delivery port in the back 10 of the brush 9 as shown in Figure 2. Then the frame 18 is placed around the tube, brush and nozzle and the clamp 17 is engaged with the keepers 25. With the parts assembled as shown in Figures 1 and 2 it is obvious that by squeezing the tube in the customary manner the contents will be fed therefrom through the nozzle and into the bristles of the brush. If desired the tube 7 the tube.

can be collapsed by sliding together the sections 18 and 20 of the frame. The complete assembled structures form a fountain tooth brush in the event that tooth paste is used 1n It is obvious however that any other toilet preparation may be contained in the tube. As the contents of the tube is utilized the sections of the frame are adjusted telescopically to insure proper maintenance of the parts of the attachment in assembled relationship.

The gist of the invention is in the provision of a detachable delivery nozzle for the existing type of neck 8 on the conventional collapsible tube 7 together with an associated bristle brush or equivalent appli-' cator, and a frame like device for holding all of these parts in assembled relation and in position on the tube, making the tube a part of the complete structure so as to permit it to be conveniently utilized cream, paste or the like in the act of using it.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size, and rearrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.

I claim:

1. In a structure of the'class described, in combination, a collapsible tube of the class described embodying a screw threaded discharge neck, a nozzle having a socket into which said neck is tapped, said nozzle including a tubular extension and a laterally directed discharge terminal, a brush including a back having bristles attached thereto, said back having an opening communicating with said bristles and a groove associated with said opening, the tubularportion of said nozzle being seated in said-groove,and the lateral terminal extending into said opening,

whereby to deliver the contents of the tubethrough the nozzle to the bristles of said brush, a retaining frame embracing the tube, nozzle and brush,'and a clamp carried by said nozzle an adjacent portion of said frame.

In a new product of manufacture, a retaining frame for holding a paste tube, a brush and a nozzle of the class described comprising a pair of U-shaped companion sections, the arm portions thereof being provided with coacting keys and keyways whereby to frictionally and telescopically connect the sections adjustably together, the intermediate portions of the arms of both sections being bent inwardly to provide keepers, and the biglit portion of said one section beyond said keepers being formed to embrace the for spreading the receiving the material passin from the nozzle, a frame embracing the rush, the tube and the nozzle and composed of a pan of telescoping sections and means for detachably connecting the nozzle with a part of the frame.

and a brush associated with the nozzle and In testimony whereof I afiix my si ature.

MAfililR.
