5 Claims.

Still another object of the invention is the provision of an applicator which when being used, does not have to actually touch the body to which it is being applied in order to discharge the liquid.

Still another object of the invention is the provision of an applicator which will pick up a uniform and substantial amount of liquid and which is easily discharged when. desired.

Another and still further object of the invention is the provision of an applicator which will remove practically the last drop of the liquid.

from a bottle and when being drawn. out therefrom, less care is necessary in avoiding touching the sides of the bottle.

Other and further objects of the invention will be apparent to those skilled in the art from a reading of the complete specification and claims.

Referring to the drawings wherein I have illustrated embodiments of my invention,

Fig. 1 shows the applicator in a bottle of the cork type, the latter being partially sectioned for the purpose of clearness;

Fig. 2 is another form of the invention as applied to a screw-type closure member of a bottle, the bottle being sectioned for clearness;

Fig. 3 is a view of my invention similar to Fig. 2 but in a different position.

Figs. 4, 4a, 5 and 6 illustrate modifications of the invention.

Fig. 7 is a modification of the form of the invention illustrated in Fig. 6.

Similar reference characters refer to the same or similar parts throughout the specification and drawings.

In providing my improved applicator, I utilize the surface tension of the liquid to be applied, to hold the same in position in the applicator. In addition to this, there is provided a construction which will withdraw practically the last drop from the bottle space and deliver it to the applicator at its delivery end.

Referring to the drawings, wherein isillustrated my invention, l0 designates the bottle wherein a cork-type top applicator is illustrated. The applicator comprises a cork stopper ll having'a knob l2 suitably secured thereto. The cork stopper has a cylindrical opening centrally located in which is installed an applicator tube I3. The tube [3 is supplied with an opening I30. at its bottom end. The tube opening 13a is of a size to provide support for the particular liquid to be dispensed considering the characteristics of that liquid.

The applicator tube I3 is also provided with a second opening [31). This opening I312 preferably extends froma point slightly above the bottom of the cork stopper to a point below the bottom of the cork-stopper to permit the liquid to enter the tube.

InpFigs. 2 and'Sis illustrated a slight modificacation of the invention. In this form a bottle H0 has an outside threaded top and is provided with a composition interiorly threaded stopper I :H having a knob H2, preferably integral therewith. applicator tube H3 is preferably embedded ,in the composition of the stopper Ill when it is soft thus not displacing the surface H Ia within the tube asclearly shown in Fig. 2. An opening M30; is provided in the lower end of the applicator tube H3 from which the liquid is dispensed. Another opening 1 I31) is provided in the tube H3 adjacent the lower surface of the stopper II E, as shown in Figs. 2 and 3.

In operation, when the bottle is full or contains a substantial amount of liquid, it is only necessary to shake the bottle to get a sufficient amount of liquid in the applicator tube through the opening 1:3?) or H.321. Upon removal of the applicator, the opening [3a or I lid is sufficiently small to permit the liquid to hold on and in the applicator until applied to the surface to be mois tened. The opening then gives up the liquid as needed.

It is when the bottle is half or nearly empty of fluid that the great advantage of the present invention is apparent. Let us assume the liquid present in. the bottle to be only a few drops. The user upon observing this fact, inverts the bottle so that the liquid is supported by the stopper. By a slight shake, the liquid will enter the opening [3b or I|3b-, any air displaced, escaping through the opening 130. or I I3a.

By now restoring the bottle to upright position, the liquid will pass down the sides of the tube l3 or H3 to the dispensing opening 13a or 3a. The user now removes the applicator and applies the liquid as desired in the usual manner. As the liquid leaves at the dispensing opening l3a or I [3a, air enters the opening l3b or I [3b.

The essential difference between the structures of Figs. 1 and 2, as far as operation is concerned, is in the space above the opening 13b in Fig. l and the lack of it in Fig. 2. However, both forms of construction operate very well. By having the collecting surface provided by the bottom of the stopper, when inverted, it will clearly be seen that all of the liquid, except that which adheres to the bottle walls will be removed during normal operation and use.

In Figs. 4 and 4a I illustrate a form wherein the stopper top and a holding cylinder may be constructed of an suitable material, such as Bakelite, the applicator means comprising a portion 2|2 integral with the closure member or stopper 2]! and a lower portion, which actually applies the liquid, fits snugly in the upper portion. The portion 2l2 has a split 2I2a which extends substantially to the under surface of the stopper or closure member 2| 1.

An applicator tube 2 l3 which, if desirable, may be provided with a split 2|3a, has an outside diameter which is a forced fit with the inside diameter of the holding cylinder 2 l2. This applicator tube may be made of glass, Bakelite or any other suitable material.

In assembling the parts it is only necessary to force the applicator tube 2| 3 into the holding cylinder 2l2 so that the split 213a, if provided, does not register with the split 2l2a. This applicator tube is forced in, only, to a point where there is still an opening through the split 2I2a over the top edge of the applicator tube 213. This opening at 2! corresponds with the openings I31; and 3b already described.

If desired, the tube 2I3 with its split 2|3a may be used with the stopper II as illustrated in Fig. 1.

In Fig. 5 I have illustrated an applicator wherein the stopper member 3 and the dispensing tube 3l2 are turned or cast and integral with each other. In such a construction, the opening 3| 4 located adjacent the lower wall of the stop-per 3| 3 and the opening 3| 3 are formed during the casting operation. To close the opening at the top of the tube 3l2, the grip member or handle 3I5 is secured in place as shown on Fig. 5.

In Fig. 6, I illustrate a stopper or closure member 4| I having an integral applicator means M2. The applicator means has an opening 2a. at its lower end and an opening 4! at the upper end at the surface of the closure member.

In constructing this modification of the invention I would preferably make it of a castable or plastic material, the applicator means 2 being made first cylindrical and then by a suitable tool with heat if necessary, nearly closed at its lower end. The opening 4 could be made by a drill or by any suitable means.

In Fig. '7, is illustrated a further modification of the invention. The closure member 5 has an extending cylindrical portion 5l2 which is provided with an opening 512a, On the outside of the extension 5l2 is a tip portion 5l3 having an inside diameter to fit the outside diameter of the extension 5l2. This tip portion 513 is provided with an opening 513a at its lower end. In this form the extension 5I2 and the tip 5l3 together form the hollow applicator means. The

.tip portion 5|3 may be made of hard or soft rubber or any other suitable material.

While I have illustrated and described my invention in detail, it is to be understood that the details of the disclosure are merely illustrative and that modifications and changes may be made within the scope of, and without departing from the spirit of, the invention, as claimed.

Having described my invention what I claim is:

1. An applicator comprising a closure member formed with a concave lower surface, hollow applicator means extending from the inner surface of the closure member, the hollow means having an opening adjacent its lower end and a second opening at the crown of the lower surface of the closure member.

2. An applicator comprising a closure member formed with a concave lower surface, a tubular applicator means including a hollow portion integral with the closure member, the applicator means having an opening at its lower end and another opening in the applicator means at the crown of the lower surface of the closure member.

3. An applicator comprising a closure member having a concave bottom, a hollow means secured to the closure member within the concave bottom, the hollow means having an opening adjacent its bottom and a second opening adjacent the surface of the concave bottom of the closure member.

4. An applicator comprising a closure member having a concave bottom, a hollow means extending from the closure member within the concave bottom, the hollow means having an opening adjacent its bottom and a second opening at the surface of the concave bottom of the closure member, the hollow means comprising telescoping sections, one within another.

5. An applicator comprising a closure member, a hollow means extending from the bottom of the closure member, the hollow means having an opening adjacent its bottom and a second opening at the surface of the bottom of the closure member, the hollow means comprising telescoping sections, one within the other.
