. 8 Claims.

This invention relates to bottles. More particularly, my invention relates to the type of bottle adapted for use as a dropper.

One of the objects of my invention is to provide, in combination with a bottle, a cap so constructed that said assembled cap and bottle may be used as a gravity dropper for dispensing medicine drops or for other similar uses.

Another object of my-invention is to provide a medicine bottle of the character described so constructed that it may be used to dispense uniform drops therefrom, and thus eliminate the necessity of supplying a dropper with said medicine bottles, and which, at the same, is adapted to be used as an applicator.

Cil

Still another object of my invention is to pro- Y vide a bottle of the character described suitable as a gravity dropper and which at the same time is so constructed that it is substantially non-rellable.

A still further object of my invention is to provide a device of the character described tion suitable for holding liquids such as medicines, and the like, and provided with a threaded neck portion Il adjacent the top edge or lip thereof.

In the types of construction heretofore employed for bottles of the character herein described, when it was desired to fill the bottle with a liquid contents which it was desired to dispense in the form of drops, it was customary to supply an extra dropper with the bottle. In certain instances, the bottle cap was constructed to support a dropper which normally dipped in the liquid. When it was desired to dispense the contents of the bottle in drop form, the cap was unscrewed and the dropper operated in the usual method of droppers, which is, to hold the dropper in the liquid and press a suction rubber which shall comprise relatively few and simple parts, which shall be easy to construct, which shall be relatively inexpensive to manufacture, which shall be neat in appearance, and which at the same time shall operate with a high degree of efciency.

Other objects 4of this invention will in part be `obvious and in part hereinafter pointed out. The invention accordingly consists in the fea` tures of construction, combinations of elements, and arrangement of parts which will be exemplii'led in the construction hereinafter described, andA of which the scope of application will be indicated in the following claims.

In the accompanying drawing, in which is shown one of the various possible embodiments of this invention,

Fig. 1 is a side elevational view, partlysectional, of a bottle and a cap construction embodying my invention;

Fig. 2 is a View of a bottle similar to that shown in Fig. 1 but illustrating a modified form of bottle. construction in accordance with, my invention; c

Figs. 3, 4 and 5 are views similar to that shown in Fig. lk but illustrating still further modified forms of my invention; and

, Fig'. 6 is a disassembled perspective view illustrating the method oi `assembly of the parts, constructed in accordance with my invention.

Referring now to the drawing, and more particularly to Fig. 1, there is disclosed a bottle III which may be of any usual type of construccap to draw a certain amount of liquid into the dropper and then to dispense the liquid from the dropper by pressing the rubber cap. Certain types of gravity bottles were also employed which tended to spill and leak when inverted.

By my invention I have provided an improved construction whereby I am able to overcome the above described disadvantages. I provide a dropper member I2 of any suitable material which may be of hollow tubular construction and provided adjacent Athe bottom edge thereof with an internally screwthreaded portion I3 corresponding to the screw-threaded portion II 0f the neck of the bottle. The member I2 is provided with an upwardly extending portion I4 having a top portion of reduced diameter or, in other words, suitable for use as an applicator. In said top portion there is provided a relatively small aperture I5 extending through the wall of the member I2. Adjacent the lower end of the upwardly extending portion I4 there is provided a vent aperture I6 open to the outside atmosphere and communicating with the interior space Il of the member I2, which in turn communicates with the interior of the bottle III. I have found by experiment that when the vent I6 is definitely positioned, with respect to the aperture I5, such a position for example. as that shown in Fig. 1 of the drawing, that when the bottle is turned upside down, the contents thereof will be dispensed through the aperture I5 only, in the form of drops of uniformsize and uniform intermittent flow. The vent I6 is so designed as to permit a predetermined amount of air to enter the space II in the form of a bubble after each drop of liquid has passed through the aperture I5. and thus continuous uniform dropping is obtained.

When the bottle is not in use for the purpose of dispensing drops therefrom, I have provided a cap I8 which is screwed to the member I2 by providing the said member I2 with an externally threaded portion I9 and the cap I8 with a correspondingly internally threaded portion 20. Mounted in the cap `I8 is a gasket or packing member 2| which is adapted, when the cap I8 is screwed on to the member I2, to close oif the aperture I and the vent I 6 to prevent any leakage of the liquid from the bottle.

In Fig. 2 I have shown a modified form of the invention illustrated in Fig. 1. In this form I provide a bottle 25 with an integral upwardly extending portion 25 similar to the portion I4, which may be of applicator shape as shown. I

tures until the bottle has been completely turned upside down, at which time, upon removal of the finger, the drops will begin to automatically and uniformly ilow.

In Fig. 6 there is shown the method of assembling the parts of my invention, as shown In Fig. 1, as well as in the other modified forms dealso provide a dispensing aperture I5 in the up'- per wall thereof, and a vent I5 in a position similar to that shown in Fig. 1. In the Fig. 2 form of device, the aperture I5 and the vent I5 function in the same manner as that shown and described in connection with the Fig. 1 form. In the Fig. 2 form, I provide a cap 21 which is screw threaded to the neck of the bottle at 26. Instead of the continuous packing 2i however, I may provide a separate packing member 29 fastened to the irmer wall of the upper portion Iof the cap 2`I which is of sufficient size to cover the aperture I5. There is also provided a second packing member 30 fixed to the inner wall of the cap 21 which is designed to cover the vent opening I6 to prevent leakage. In the form of my invention illustrated in Fig. 2, it is seen that I have provided a substantially non-reiillable type of bottle which is at the same time a gravity dropper bottle for dispensing a uniform flow of drops.

In Fig. 3 I have shown another modified form of my invention, in which the cap 3| is provided with a flange 32 at the lower edge thereof, extending outwardly from the side wall of 'said cap and which is adapted to lie adjacent the ange 33 in the dropper member 34. The dropper member 34` is screwed to the neck of the bottle I0 in a manner similar to that shown in Fig. 1. The dispensing aperture I5 and the vent aperture I6 are of similar construction and may be similarly disposed to that shown in Figs. 1 and 2.

In Figs. 4 and 5 I have disclosed still anotherV modied form of my invention, the Fig. 4 form being similar in construction to that shown in Fig. 3 with the exception of the vent aperture 35 which, instead of being disposed as shown in Figs. 1 to 3, is disposed at right angles thereto and in the flange 33. 'Ihe Fig. 5 form of device is similar in construction to that shown in Fig. 2, since the applicator shaped dropper portion 36 isintegral with the bottle 31. There is also provided a vent aperture 35 which may be similar in construction and arrangement to the vent aperture shown in Fig. 4. In the Fig. 5 form, however, it is noted that the cap 38 is threadedly attached to the neck of the bottle by having the side flanges 39 thereof extending downwardly and provided with an internally threaded portion as shown. Y

It is noted that the vents 35 in the Figs. 4 and 5 -forms of construction are positioned adjacent the lip of the bottle opening. It has been found by thisconstruction that a better and more uniform ow of drops is obtained.

It is also noted that inthe constructions illustrated in Figs. 1 to 5, when the cap is removed, a finger of the person using the' bottle may be placed over the vent aperture to prevent any drops from flowing through the dropping aperscribed above, in which the dropper member is screwed to the threaded portion of the neck of the bottle and the cap thenv screwed to the threaded portion of the dropper member.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made` in the embodiments above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawing is to be interpreted as illustrative and not in a limiting sense.
