POUR FACILITATING DEVICE RECEPTACLES FOR Raymond Olson, Chicago, Ill.
Application December 26, 1946, Serial No. 718,349
2 Claims. (Cl. 215 -31) This invention relates to a new and improved pour facilitatin device for receptacles and has for one of its principal objects the provision of means for controlling a pouring stream from receptacles.
An important object of this invention is to provide an integral lug means for the mouths of bottles or the like in the form of a radially extending narrow projection and adapted to facilit-ate pouring of liquids from a bottle by minimizing the width of stream and simultaneously preventing dripping after pouring from the. bottle is ended.
Another important object of this invention is to provide a pour controlling means on the tops of bottles.
A further object of this invention is to-combine the pourcontrolling means of this invention with the usual cap or closure threads associated with the mouth or neck portions of bottles or the like.
Other and further important objects of this invention will become apparent from the disclosures in the following specification and accompanying drawings, in which:
Figure 1 is a side elevational view of a glass tube having the'pouring projection of this invention mounted thereon.
Figure 2 is a view similar to the device of Figure 1 showing the tube in inclined pouring position.
Figure 3 is a front view of the device as shown in Figure 2.
Figure 4 is a side elevational view of a bottle incorporating a plurality of the pouring projections of this invention in combination with the bottle closure threads.
Figure 5 is a top plan view of thedevice as shown in Figure 4.
Figure 6 is a side elevational view of another modified form of bottle having a plurality of separate pour lugs around the mouth thereof.
Figure '7 is a top plan view of the device as shown in Figure 6.
Figure 8 is a side elevational view of still an other modified form of bottle top having the pour facilitating features of this invention.
Figure 9 is a top plan view of the device as shown in Figure 8.
As shown in the drawings:
The reference numeral III indicates generally a glass tube. The tube as shown is of a. type commonly used in chemical laboratories, but it is r to be understood that any receptacle regardless vention incorporated thereon. The top of the tube has an annular lip II outlining the mouth thereof. A radially extending narrow projection I2 is fixed on the outside of the tube and is flush with the top of the annular lip II. The projection I2, as best shown in Figure 3, is relatively narrow and controls the width of liquid pouring stream; When the liquid is poured from the receptacle there is a tendency for. the liquid to follow the outside of the receptacle or, in other words, to curve inwardly and roll down the sides of the bottle or the like. As shown in Figures 2 and 3, the tube It] is inclined in a pouring position in such'a manner that the projection I2 receives the liquid as it progresses from the inside of the tube and tends to aggregate the stream I3 and direct it outwardly and down- Wardly in a stream substantially the width of the projection I2. The lateral extension I2 is of such a length that dripping after pouring has ceased issubstanti'ally eliminated.
Figure 4 shows a bottle I4 having a neck portion I5. The neck I5 is provided with spaced threads I6 in helical paths for the purpose of receiving a cap or closure having complementary threads therein (not shown). In order to facilitate pouring from this threaded top bottle, the threads are terminated as shown at I! short of the top of the bottle I8. Projections I9 corresponding to the projection I2 in Figures 1, 2 and 3 are placed on the top rim of the neck I5 and in alignment with the thread helixes to form continuations of the spaced ends I! of the threads It so that a threaded cap may be used without hindrance from the pour facilitating projections I9. In Figure 5 it will be noticed that there are four such projections I9 spaced at regular intervals around the periphery of the bottle neck I5. With this construction it is possible to pour liquids from the bottle at any point where a projection I9 exists. The projections I9 as the projection I2 aggregate the liquid and provide a smooth thin fiow without fear of turn back" onto the bottle. The purpose of the space between the projections I9 and the threads I I5 is quite obvious. If there were no space the liquid would tend to follow the threads I6 and down the surface or side walls of the bottle. In the present instance, however, the space between the tle 20 having a neck 2| is provided with a plurality of narrow projections 22 at spaced intervals around the top surface of the neck. At each projection 22 pouring liquid, contained within the bottle, is facilitated. It should be understood that each projection is provided with a substantial distance of smooth surface on the bottle neck on each side thereof so that pouring streams are adequately separated and there is no tendency of the streams to run together.
The modifications of Figures 8 and 9 are slightly different from those shown in Figures 4 to 7, inclusive. A bottle 23 has an upwardly extending neck 24. The neck 24 has integrally raised threads at the base thereof as shown at 25. A cap or cover having corresponding threads may threadedly engage the threads 25 in order to close and seal the bottle 23. The upper portion of the neck 24 is of smaller diameter as shown at 26, and projections or lugs 21 are placed at intervals around the surface of the restricted top portion of the" bottle neck 26. These projections 21 act to facilitate pouring in a manner similar to the projections l2; I9 and 22 of the receptacles shown in the preceding figures. The top of the bottle 23, as shown in Figure 9, has a mouth 28 with an annular top portion or lip 29 which is the top of the restricted portion 26. The radial projections 21 are of such a length and extend outwardly less than the large diameter base of the neck 24, and hence the pour facilitating projections 2.1 do not interfere with a cap or cover to be screwed onto the bottle 23.
It will be understood that the pour facilitating projections of this invention may be used on 7 bottles or receptacles of all types in which it. is desired to pour a liquid or other material therefrom.
Manydetails of construction may be varied throughout a wide range without departing from the principles disclosed herein, and I, therefore do not, propose limiting the patent granted hereon otherwise, than as necessitated by the appended claims.
What is claimed is:
1} A pour facilitating device for bottles comprising in combination a bottle having an opening in the top thereof, a neck for said bottle defining said opening, said neck being cylindrically shaped and having a raised thread in a helical path thereon for threadedly receiving a bottle closure, said thread terminating at a point spaced beneath the top of said neck, and 2. lug on said neck adjacent the top thereof and spaced from the upper end of said thread, said lug being in alignment with a continuation of the path of the; thread helix, whereby the lug performs the dual function of permitting the receiving of a threaded closure and making pouring of liquids from the bottle at the point of the lug easy.
2. A pour facilitating device for bottles comprising in combination a bottle having an opening in the top thereof, a cylindrical neck for said bottledefining said opening and having a plurality of separate peripherally spaced raised thread helixes thereon, said threads adapted to receive a threaded bottle closure, each of said threads terminating at points spaced beneath the top ofv said neck, and. a plurality of lugs spaced around the top of said bottle neck, each one of said lugs being in alignment with a continuation of the path of one of said thread helixes, whereby the lugs perform the dual function of facilitating the initial engagement of the bottle closure and facilitating pouring of liquids from said bottle at the points of each of said lugs.
