1 Claim. (01. 221-143) This invention relates to closures for containers and has for an object the provision of new and improved devices of this character.

In the drawing accompanying the specification 5 and forming a part of this application I have shown, for purposes of illustration, various forms which my invention may assume, and in this drawmg: CIA

Figure 1 is an elevational view, showing an illus- 10 trative embodiment of my invention as applied to a bottle,

Figure 2 is a vertical sectional view corresponding to the line 2-2 of Figure 1, while Figure 3 is a view similar to Figure 2 but show- 1 ing a difierent embodiment of my invention.

In the embodiment of my invention shown in Figures 1 and 2, there is provided a member 11 of soft rubber or like material, formed with a skirt portion 12, having screw-threads 13 adapted to engage corresponding screw-threads formed on the neck of a bottle 14. The skirt portion 12 is formed with an integral wall 15 and an integral bulb 16, and the wall 15 is thickened and provided with a bore 17 extending transversely there- 25 through, and the wall of the bore 17 is provided with a groove 18 of considerable width, and adapted to accommodate a flange 19 formed on one end of a dropper tube 20.

, The skirt portion 12 is also provided on its outer 30 surface with a groove 21, adapted to contain a rigid reinforcing member 22, preferably formed of hard rubber. It will be understood, however, that the member 11 can be used without the backing member 22, provided it is made of material flexible 35 enough to allow the bulb 16 to be flexed and still rigid enough to give the skirt member 12 a suitable stifiness.

A feature of this construction resides in the provision of a skirt portion, and a bulb portion form- 0 ing a bottle closure and liquid dropper and of integral formation, being preferably formed of a flexible material such as soft rubber and because of the -flexibility of the material, the wall 15 not only connects the bulb portion 16 with the skirt portion 12 45 but also acts as a sealing member to contact the bottle neck and seal the bottle. Another feature resides in the provision of a bore 17 establishing communication between the bulb portion 16 and the skirt portion 12, and having a groove 18 of considerable width to adjustably secure the flange 19 of the dropper tube 20. With a construction of this type, the dropper tube may be adjusted in the groove 18 to provide for various sizes of bottles.

In the embodiment shown in Figure 3, there is provided a member 23, of flexible material, such as soft rubber, formed with a skirt portion 24, a thickened integral wall 25 having a bore 26, and an integral bulb portion 27. The Wall of the bore 26 is provided with a groove 28 of such width as to tightly clamp a flange 29 formed on one end of the dropper tube 30. The skirt portion 24, in this embodiment, is formed with a groove 31 on its inner surface containing a rigid member 32 of hard rubber, or like material, having screw-threads 33 adapted to engage corresponding screw-threads formed on the neck of the bottle 14.

A feature of this construction resides in providing the flexible skirt 24 with a rigid portion performing the dual function of reenforcing the skirt member and providing rigid threads for engagement with the bottle neck. 2O

, It will be understood by those skilled in the art that the disclosure herein accomplishes at least the principal object of my invention, and it will further be understood that the invention has uses and advantages other than those herein particu larly referred to, and it will be apparent that various changes and modifications may be made without departing from the spirit of the invention; .accordingly it will be appreciated that the disclosure herein is illustrative only and the invention not limited thereto. a

I claim:

A combined bottle-closure and liquid-dropper, comprising: a cap portion, adapted to be positioned over the mouth of a bottle, and having a skirt adapted to engage the exterior of the neck of the bottle to secure said bottle-closure and liquiddropper in position on the bottle; a dropper tube, provided at its bulb end with an external flange; the top of said capportion being provided with an 40 aperture receiving and holding said end of said tube, and the wall of said aperture being recessed to receive said flange, and said recess being of considerable extent longitudinally of said aperture relative to such extent of said flange, to permit relative longitudinal adjustment of said tube; and a flexible bulb portion, rising from said top exteriorly of said aperture, and opening and communicating with said tube through said aperture.
