NON-DRIP INSERT FOR BOTTLES Filed July 14, 1955 INVENTOR. WILLIAM OPSITNJK ATTORNEY United States Patent Ofice NON-DRIP INSERT FOR BOTTLES William Opsituik, Youngstown, Ohio Application July 14, 1955, Serial No. 521,964

2 Claims. (Cl. 215-73) This invention relates to a device to be inserted in the neck of a bottle to prevent the bottle from dripping when the contents of the bottle have been poured therethrough.

The principal object of the invention is the provision of a non-drip insert for a bottle.

A further object of the invention is the provision of a simple and inexpensive device which is insertable in the neck of a bottle to provide a channel through which the contents of the bottle may be poured and a chamber about the channel to catch the fluid that would otherwise drip from the bottle.

A still further object of the invention is the provision of a non-drip insert for a bottle incorporating an unobstructed pouring channel and an annular drip receiving channel thereabout with a check valve controlling the flow through the drip receiving channel.

A still further object of the invention is the provision of a non-drip insert for a bottle which may be molded from a suitable synthetic resin.

The non-drip insert for bottles disclosed herein comprises a cylindrical member insertable in the neck of a bottle containing liquid to provide a pouring channel and a drip receiving channel so that the contents of the bottle poured therethrough will not drip from the neck of the bottle.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being the intention to cover all changes and modifications of the example of the invention herein chosen for purposes of the disclosure, which do not constitute departures from the function and scope of the invention.

The invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a vertical cross section through a portion of a bottle illustrating the non-drip insert therein.

Figure 2 is a top plan view taken on line 22 of Figure 1.

Figure 3 is a horizontal cross section taken on line 3-3 of Figure 1.

Figure 4 is a top plan view of a modified form of nondrip insert.

By referring to the drawings and Figures 1, 2 and 3 in particular it will be seen that a neck portion of a bottle has been illustrated with a cylindrical pouring spout comprising a cylindrical member 11 disposed therein in spaced relation to the inner walls of the bottle 10. The cylindrical member 11 is provided with a plurality of circumferentially spaced radially extending ribs 12 longitudinally thereof and on the exterior thereof which engage a sleeve 13 provided with an annular flange 14 at its uppermost end and adapted to closely engage the inner walls of the neck of the bottle 10.

The space between the cylindrical member 11 and the sleeve 13 comprises an annular chamber 15 divided into 2,750,063 Patented June 12, 1956.

a plurality of vertically extending sections by the plurali ty of ribs 12. The lower ends 16 of the ribs 12 extend below the lower ends of the cylindrical member 11 and the sleeve 13 and through circumferentially spaced apertures in a washer 17 which is thereby loosely mounted in normally spaced relation to the lower ends of the parts of the annular chamber 15 and capable of acting as a check valve to close the parts of the annular chamber 15 when the fluid contents of the bottle flow thereagainst as will occur when the bottle is tipped.

It will be observed that the washer 17 permits the fluid contents of the bottle to flow through the cylindrical member 11 which forms the pouring spout while preventing the fluid from entering the parts of the annular chamber 15. Thus, when the bottle is replaced in an upright position, the liquid which would ordinarily flow over the edge of the neck of the bottle and drip, will flow downwardly in the parts of the annular chamber 15 and back into the bottle.

It will occur to those skilled in the art that the cylindrical member 11, the ribs 12 and the sleeve 13 may be molded of a suitable synthetic resin in an integral shape, preferably somewhat resilient, so that the sleeve 13 can accommodate such irregularities in the size and shape of the bottle neck as may occur.

The washer 17 is assembled over the ends 16 of the ribs 12 and the same headed to retain the washer 17 in place.

The device is capable of being inserted into bottle necks by automatic machinery.

Modifications in the construction will occur to those skilled in the art and one such modification is illustrated in Figure 4 of the drawings wherein the bottle is indicated by the numeral 18. The pouring spout is defined by a cylindrical member 19 provided with a plurality of circumferentially spaced, outwardly extending flanges 20 having a washer 21 loosely secured to their lowermost ends in the same manner as in the preferred form of the invention as in Figure 1 of the drawings and capable of effecting a closure between the inner wall of the bottle 18 and the lower end of the cylindrical member 19 when the bottle 18 is inverted.

It will be observed that in the modification the sleeve 13 is dispensed with and that the longitudinally positioned, outwardly extending flanges 20 directly engage the inner walls of the neck of the bottle 18.

It will thus be seen that the non-drip insert for bottles disclosed herein provides a simple and eflicient means of directing the fluid contents of a bottle to a spout positioned centrally of the neck of the bottle and in spaced relation thereto so that when the bottle is moved to upright position the fluid about the open end of the spout will flow into the area between the spout and the bottle neck and thus prevent dripping of the fluid from the neck of the bottle.

It will thus be seen that the several objects of the invention are met by the non-drip insert for bottles disclosed herein.

Having thus described my invention, what I claim is:

1. A non-drip insert for a liquid dispensing bottle comprising a cylindrical pouring spout, means for positioning the spout within the neck of the bottle in spaced relation with the inner wall thereof to provide longitudinal drip return passages exteriorly of the spout extending from the upper end to the lower end of the same and in communication with the space directly below the lower end of the pouring spout, said means including a plurality of circumferentially spaced longitudinally extending webs on the exterior of the pouring spout, said webs having lower end portions extending a short distance below the lower end of the pouring spout, and a valve of washerlike form having a central opening therein mounted for limited vertical sliding movement on said end portions of said webs, the valve being provided with a plurality of circumferentially spaced apertures outwardly of its central opening slidably engaging said end portions of said webs, said valve acting to close said longitudinal drip return passages at the lower end thereof when the bottle is moved to pouring position, the central opening of the valve being in communication with the interior of the pouring spout.

2. A non-drip insert for a liquid dispensing bottle comprising a sleeve adapted to be inserted into and to closely engage the inner wall of the neck of the bottle, a cylindrical pouring spout disposed within said sleeve, a plurality of circumferentially spaced longitudinally extending webs between and connecting said sleeve and spout in spaced relation to provide longitudinal drip return passages extending from the upper end to the lower end of the pouring spout and in communication with the space directly below the lower end of the latter, said webs having lower end portions extending a short distance below the lower end of said sleeve and pouring spout, and a valve of washer-like form having a central opening therein mounted for limited vertical sliding movement on said end portions of said webs, the valve being provided with a plurality of circumferentially spaced apertures outwardly of its central opening slidably engaging said end portions of said Webs, said valve acting to close said longitudinal drip return passages at the lower end thereof when the bottle is moved to pouring position, the central opening of the valve being in communication with the interior of the pouring spout.
