2 Claims.

The invention relates to a drop-preventing device, and is constructed in the form of a spout to be used on bottles or similar receptacles. In the case of all contrivances known up to now, no provision at all has been made to prevent the developing of drops when the bottle is raised to an upright position again, after having been inclined in order to pour out the liquid, or, at least, this result has only been partly attained. Other contrivances, which are constructed so as to catch drops having developed during the process of pouring out the liquid, have the disadvantage that a considerable quantity of the liquid being poured out is lost, after having absorbed Ward direction and is preferably inclined towards the outside in a downward direction, so that its limited adhesive surface practically renders the developing of drops and the flowing down of liquids along the neck of the bottle impossible.

The drawing shows a working example of the contrivance which has been made the subject of this invention. It shows in Fig. 1 the contrivance in longitudinal section according to the line I-I of the Fig. 2.

Fig. 2 the contrivance in top view.

Fig. 3 the contrivance in side elevation.

Figure 4 is a fragmentary detail sectional view showing the upward inclination of the bottom face of the annular rib or ring flange.

The device consists of an upper part a and a lower part b, which are separated by an annular rib d.

The bottle spout should preferably be constructed entirely as a pressed or drawn piece with the middle annular rib d, which is set or riveted on. Part b is fitted with a jacket, which is adapted according to the size of the opening of the bottle and should preferably be tapered towards the lower end and manufactured from cork etc. The upper part a ends atthe top in an annular rib or drop-holding flange c, which is inclined in an outward direction. It is advisable that this annular rib is inclined in an outward and downward direction. At the same time, the lower face of the annular rib will preferably be inclined in an upward direction towards the neck of the bottle as shown in Figure 4. The upper edge of part a. can be constructed either 5 with sharp edges as is shown in the working example on the illustration or rounded. The annular rib a should be narrow. Thus, a limited adhesive surface is created which practically renders impossible the developing of drops and the flowing down of liquid along the neck of the bottle. In so far as drops have not yet been distributed over the upper surface of the flange c by means of the effect of adhesive power, such particles of liquid as have developed into a drop can run only to the lower part of flange c, which, in the same manner as the upper part, exercises an adhesiveand distributing influence upon the drop. As the lower face of the flange c is inclined in an upward direction towards the centre of the opening from which the liquid is poured out, it is not possible for the liquid to flow farther. Owing to the capillary effect between the upper and the lower part of the annular rib or holdingflange c, suction is exercised on the liquid in an 5 upward direction so that in conjunction with the adhesive power of the surface of the annular rib distributes and spreads any drop, thus exercising greater holding power over the same.

What I claim is:

1. In a drop-preventing device in the form of a spout to be used on bottles, a tubular spout, a relatively narrow ring flange at the opening of the spout arranged in an outward direction with its upper surface of frusto-conical formation and its lower surface inclined in a downward direction towards the outer edge of the ring flange, the limited adhesive surface of said flange practically rendering impossible the development of drops and a flowing of the liquid in a downward direction along the neck of the bottle.

2. In a drop-preventing device in the form of a spout to be used on bottles, a tubular spout, a relatively narrow ring flange at the opening of the spout arranged in an outward direction with 5 its upper surface of frusto-conical formation, the ring flange also at its underside being inclined in an upward direction from the outside towards the neck of the bottle defining a relatively sharp marginal edge for the ring flange.
