N. Y., a corporation of New York Application July 14, 1944, Serial No. 545,018 3 Claims. (Cl. 215-79) This invention relates to an accessory which facilitates the transference of liquids from con-- 1 tainers by gravity by employing the force of surface tension of the liquid to prevent leakage. This is accomplished by neutralizing the vacuum in the container created by the transference of the liquid in that the use of properly determined orifice or orifices-located in the accessory-permit the ingress of air, while at the same time the predetermined limitation of the diameter of size of these openings allows surface tension to prevent the leakage of fluid.
This invention further relates to the providing of a sanitary and convenient means for the drinking from a container all types of liquids (beer, milk and milk products, water, soda. cola and other soft, alcoholic and non-alcoholic drinks) and dispenses with the use of glasses, cups, straws, etc, and by its conical shape permits easy insertion into the container and efiectively seals the space between the accessory and the neck of the container. Moreover, the conical shape permits nesting in packaging. Various attempts have been. made to provide devices for this purpose but objections inherent in the principle employed, the construction, function and operation have prevented a general use of the same. Embodiments of the invention may be applied to other uses.
This invention consists generally of an accessory adaptedto act as a valve in a low pressure system made of non-wettable material, consisting of a partition to separate two fluids, said partition. having means for communicating one fluid with the other, said means to utilize the variances of surface tensions of said fluids, to allow for the ingress of one withoutpermitting the egress of the other, the surface tension forces of the one fluid being at all times greater than forces capable of moving the fluid through said means,
said surface tension forces causing the fluid to bridge the surface areas of the means.
The invention will be more fullyv described hereinafter and various embodiments thereof will be shown in the drawings, and the invention will be finally pointed out in the claims.
In the accompanying drawings,
Fig. 1 is a front view of'the improved accessory held in a position of non-use and applied to a bottle;
Fig. 2 is a side view of a bottle;
Fig. 3 is a perspective view showing the manner of use of the improved accessory;

Fig. 7 is a side view of an accessory having slits circumferentially placed;

user. The accessory shall taper to an angle of- /2 to 8 which is to provide:
1.- Nesting for saving of spaceand for easy packaging.
2. Adaptability openings. 3. Self-wedging and firm attachment to container openings.
to various diameter container Any variation of thistaper from within this angular range will not provide all three features. The accessory relies on the surface tension of. .the liquid to prevent leakage,.,yet permits the passage of air to neutralize the vacuum created. above the liquid in the container so that the;
liquid readily flows. The improved accessory hasvery small openings, so small as to insure a sealing by the surface tension of the liquid of said openings, which thereby prevent the liquid from passing through these openings. Air, however, under atmospheric pressure can find its way through the liquid to provide neutralization oi.
- ing through the accessory the liquid will through surface tension close the openings against itself but not against the air which under atmospheric pressure will 'continuously enter the container.
The applicable rule is: When the circumference of the hole or opening. or conduit, is multiplied by the surface tension of the fluid, it should equal or slightly, exceed the weight of a column of the fluid having the same circumference and a height which height will equal its operational knowledge of the surface tension of the liquid, that the area of the hole can be determined. My invention includes applications of this concept to include the use of the force of surface tension to allow for the neutralization of a vacuum to prevent leakage. Such instance as this. for example, is when the hole is extended to a canal or conduit as by an overlap in the accessory as shown in Fig. 5a and in which the circumferential openings are omitted, and the orifice Ha has such a predetermined size that the surface tension of the liquid in the container prevents the passage of the liquid through the orifice, and the force of surface tension is coupledwith a time factor in the prevention of leakage... This embodiment would omit the circularly disposed holes H of The accessory has one or more holes or openings exterior to the container of the liquid, such holes having an area over which the liquid will pass without entering the hole, save only such convexity as results from the weight of the liquid restrained by its surface tension forces. A plurality of such holes can be circumferentially or head. It is from this relationship, with thelongitudinally, or otherwise arranged. Slits or slots may be substituted for the holes and the disposition of the holes, slits or slots need not be necessarily uniformly arranged, provided such holes, slits or slots are free from the container and from the mouth, when accessory such as is applied to a bottle, is being used.
U Referring to the drawings, the improved accessory is made from a rectangular sheet of material of sufliclent stiffness and of a non-wettable surface to maintain its shape and of sufficient inherent resiliency to return to its initial position.
This sheet is molded, or rolled to shape by mechanical means such as by overlapping its longitudinal ends into a lap Joint as shown in Fig. 5, glue or other holding means being supplied. When so fashioned it is generally cylindrical with, homer, one end of slightly less diameter than the other end, whereby the cylinder becomes slightly tapered. One example of one end adapted to be inserted into the container is shown in Figs. 2, 3 and 4. The slightly tapering shape brings about a tight hold when inserted in the container. In Fig. 4, the accessory ID has about at is median position a circumferentially disposed series of openings spaced from each other. One of these openings issuflicient to carry out the invention. The exterior air enters theopening but the surface tension of the fluid'will-prevent the fluid from passing out of the opening yet enables the proper neutralization of the vacuum above the fluid. A plurality of such openings increases the air'inflow into the container thereby, acceleratin the neutralization of vacuum above the fluid. By arranging the openings circumferentially or otherwise an position of the accessory in the container will make it operative, and no particular attention need be given to the positioning of the openings. It is essential that the openings be in communication with the atmosphere or comparable fluid as generally shown in Fig. 4. Should a canal or conduit be used as in Fig. 5a as an alternets to the openings II for example its external hole that is in the plane passing through the tip of the bottle must still occupy a position external to the container and the lips of the user. if the embodiment be used. Slits or slots l2 as shown in Fig. 7 or other configurations may be used, and the material may be specially prepared to provide interstices in a circumferential or other zone, where the openings are now shown, the remaining parts of th material being more compressed or compacted provided always that the foregoing relationships between external pressure of the 'air or atmosphere, surface tension, forces of the fluid, height or column above the opening, etc. be followed. I
The invention described may be applied to other uses; for instance, difllculty has been encountered in transferring a fluid suitable for injections due to the desire to keep such fluid free from contamination of the atmosphere or oxidation of the atmosphere. In Figure 8 the sealed bottle 20 has a tube 2| inserted through its cork 22, to which tube 2|, a flexible tube, with a control device 24 is attached to the free end of which tube 23, an injection needle 25 is applied to the arm of the patient. In the tube 2|, there are arranged either circulary, or in alignment, or
- otherwise, small surface tension openings 21 as described permitting entrance of air, but preventing exit of any of the fluid.
In Figure 9, the filled closed vessel 30 has a conduit 3|, communicating with another Vessel 32 to be filled. The conduit 3| has the surface tension holes 33 as described. In Figure 10, when it is desired to mix two fluids, one fluid passes through the pipe 40 which is provided with the surface tension holes 4|. Surrounding this portion of the pipe 40 is a hollow ring 42, the interior of which is supplied by a pipe 43 with a fluid which will enter the surface tension openings 4|. These openings, however, prevent the fluid inthe pipe 40 to pass outwardly through such openings.
Much difflculty has been encountered with baby feeding by bottles with nipples. Bleed channels have been provided. In Figure 11 a nipple 50 is applied to a bottle 5|. The nipple 50 is provided with surface tension openings 52, preventing egress of the fluid, but permitting inlet of the a r.
The accessory may be enveloped in a Cellophane like wrapper 5 as shown in Fig. 1, with itswould ordinarily hinder this manner of :drinking; adequate amounts of liquid can be secured directly from the container. The anti-vacuum feature utilizes the balancing of the fluid weight against its surface tension to provide a leakless means of neutralizing the vacuum created when drinking.
The sizes of the holes, slits or slots are of the greatest importance; their size is determined by mathematically balancing the physical property of surface tension of the liquid used against the weight of a column of the liquid which is determined by the height of the fluid above the vent or its operational head and the diameter is equivalent to the size of the hole. The surface tension about the hole is obtained by multiplying the circumference of the hole by the known surface tension of the fluid (in the case of water 75 dynes per centimeter multiplied by the circumference of the hole in centimeters) which gives the total force of the surface tension which must act against the weight of the column of fluid. The weight of the column is determined by multiplying the total volume by the specific gravity of the fluid. The surface tension force must equal or exceed the weight of the column of fluid. If the drinker uses about a angle of the container to the horizontal a pin hole size of hole will result from calculations, and this can be more accurately determined for various liquid as well as any angle of tilt employedin drinking from the container.
I have described several forms of my invention, but obviously various changes may be made in the details disclosed without departing from the spirit of the invention as set out in the following claims.
