1 Claim.

The present invention relates to improvements in bottles or other containers for liquids and, more particularly, to improved means for preventing drippings from running down the outside surface of the container, especially containers having a restricted discharge orifice commonly known as a sprinklertop.

An object of the invention is to provide a finish of the character described having a novel sealing surface adapted to prevent leakage of contents containing oil.

' Another object is to provide a sprinkler finish for a container which includes novel means for draining back drops of fiuid and preventing them from running down the outside of the bottie and in addition acting as a filling aid.

Other objects and advantages will be in part apparent and in part pointed out in the course of the following description, in which:

Fig. l is a plan view of my invention;

Fig. 2 is a vertical sectional view taken on line 2-4 of Fig. 1, showing a closure applied to the bottle finish; and

Fig. 3 is a similar view showing the bottle finish with the closure removed.

The ring ill provides a more reliable seal for products of an oily nature such as hair oil, Brilliantine or the like, than is possible on bottles of this nature now generally in use.

The cap 8 (Fig. 2) represents a molded closure provided with a cork liner ll although it is to be understood that various other types 01 caps and liners may well be employed. Theplacing of the ring Hi near the margin of the finish permits greater pressure to be applied to the cap to force the liner into sealing contact with the ring. Heretofore, breakage of the molded caps has been experienced due to the usual sealing surface being relatively closeto the center of the cap, thus placing considerable strain on the closure at its weakest point. i

An axially disposed filling and discharging opening i2 is located concentric with and below the ring I 0 on the face 9 and provides a restricted orifice through which the contents must be shaken when the bottle is inverted. The surface l3 lying between the ring In and the orifice l2 no provision for eliminating. the dripping of excess fiuid which is allowed to run down over the bottle and present not only a messy appearance but otherwise generally make the bottle moon venient to handle.

The sloping portion l3 in addition to providing a drain facilitates the filling of the bottles. By placing the sealing ring HI nearer the periphery of the neck the sloping portion I3 is provided with a maximum of drain surface between the ring and the opening, thereby providing a larger area as a filling guide. When bottles now in use are placed in the filling machine, it is of utmost importance that they align perfectly with the filling tubes, The filling tubes are of necessity made from light weight tubing of small diameter and are readily bent, broken or otherwise damaged should they strike the finish before entering the bottle. The sloping portion l3 serves as a guide for the filling ,tube, permitting the bottle to shift on its support should it not be properly placed in the machineat the time of filling.

Modifications may be resorted to within the spirit and scope of the appended claim.

I claim:

A sprinkler top bottle having a neck portion provided with a relatively thick annular wall having a cylindrical outer surface provided with an external thread, said neck portion having an annular fiat marginal top portion extending inwardly from said cylindrical outer surface, said nicating with the interior of the bottle, said bore having a filling opening at the-top thereof positioned below the level of said head, the top surface of the neck portion between said bead and opening sloping downwardly and inwardly, the

10 being or a diameter slightly less than the diameter of the cylindrical outer surface of the bottle neck wall and of a height less than the extent to which said liner may be compressed upon manual application of torque to said cap whereby when excessive torque is applied to said cap said rounded edge will engage the underneath side of said liner in a circular reinforced region in the vicinity of said skirt and prevent breakage of said cap.
