REENFORCED APPLICATOR CAP.

Application filed ranaury 23, 192'5.

I This invention relates to an improvement in. applicators for massaging purposes. These applicators are generally made of rubber or the like and are adapted to Lt upon an ointmentbottle when in use. The

applicator is usually provided with ointmentV feeding teats having ducts leading therethrough. During the operation of the applicator, these ducts sometimes beca-me partially closed or' clogged through the flexing ofthe rubber. Toovercome this objection1 it has beenproposed to enlarge the outer and innerportions of the du'cts in the ointment feeding teats. While this structure greatly overcame the previous objection, the manufacturing process thereof was somewhat dif- ;ticultand expensive. In practice it has been found that thesel rubber applicators bulge iipwardl. and the teats bulge outwardly more or less, dueto the expansion caused by the ointment. This bulging tends to restrict the flow of ointment through the teats.

The problem herewith concerned seeks to overcome this objection in the provision of an applicator that resists the outward bulging 'eect of the ointment feeding teats, that always maintains a sufficient flow of ointment and that can be economically manufactured.

The invention comprises the novel structure and combinations hereinafter described and more particularly pointed out and delined in the appended claim.

In the accompanying drawings which illustrate a preferred form of this invention and in which similar reference numerals refer to similar features in the different views:

Figure l is an elevational view of an ointment bottle equipped with an applicator involving this invention.

Figure 2 is a sectional view upon the line II-II of Figure 3.

Figure 3 is an enlarged vertical sectional view of the applicator showing a fragment of the ointment bottle attached thereto.

Figure 4 is a view similar to Figure 3 illustrating the form of the applicator after acted upon by the ointment.

As shown on the drawings:

or nipples 4, having suitable ducts 5 efrtending therethrough and through the base of the applicators. These ducts are of uniform bore and of sufficient size to prevent the same from closing or restricting-the iow of ointment4 on account of the iiexure arising from the operation of the applicator.

A metal plate 6 is embedded in the base of the applicator and is provided with small apertures 7 coaXially with the ducts 5. This plate member will reenforce the rubber disk and prevent the outward bulging of the ointment feeding teats 4; at the same time the smaller apertures in the plate 6 will restrict the iiow of ointment to the desired amount. There will, however, be an upward bulging of the top of the disk as shown in Figure 4; the flexure occurring between the margin of the plate 6 and the attaching ange of the disk, whereby the massaging nipples will bulge outwardly bringing their tops nearer to the tops of the teats 4 which will remain vertical. In other words, the portion of the dislrcontaining. the plate 6 will be elevated in a straight horizontal plane.

The lower surface of the disk is provided with the rib 8 that is adapted to expand against the neck of the bottle, and a circular expansion groove 9 concentric of said rib and located within the confines thereof.

It will be appreciated that the large uniform bores in the ointment feeding nipples or teats simplifies the manufacture thereof, and the embedded reenforcing plate 6 not only restricts the flow of ointment that would naturally ow through the ducts; it also resists the outward bulging of the ointment feeding nipples and prevents the ducts therein from partially closing so that the steady desired flow of ointment is secured.

I am aware that many changes may be made, and numerous det-ails of construction may be varied through @L Wide Irange without departing from thevprineiples of this invention, and I therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

claim as my invention:

An applicator, comprising' a flexible disk having ointment feeding" nipples With enlarged uniform bores, and a metal plate embedded in and surrounded by the material o1 seid disk and having' smaller apertures than said bores in registry therewith.

In testimony whereof Ihave hereunto subscribed my name.
