R. s. SKINNER CLOSURE FOR CONTAINERS Feb. 21, 1939.

Filed Sept. 11, 1936' JIENTOR Patented Feb. 21, 1939 nmrso STATES PATENT OFFIE 2 Claims.

This invention relates to closures for bottles and other containers, and has for its main object the provision of a novel means for preventing a fluid from being spilled from the bottle or con- 5- tainer, when accidently tilted or upset, while at the same time providing free access to the interior of the container.

Other particular objects of the invention are to provide a closure for ink bottles and ink wells which prevents an excess of ink remaining on a pen point after the point has been dipped into the ink; which prevents the necessity of dipping the pen to the bottom of the bottle; which makes possible the using of all the ink in the bottle, even though there is hardly enough to cover the bottOlllOf the bottle; which prevents evaporation of the ink; which prevents the sides of the pen holdor from becoming soiled by contact with the sides of the bottle; and, which will be efficient in accomplishing all of the purposes for which it is intended.

Heretofore, devices of this kind have made use of an auxiliary valve to accomplish the above objects. My attachment has no such valve.

With these and other objects in view as will more fully appear hereinbelow, my invention consists in the construction, novel features, and combination of parts hereinafter morefully described, pointed out in the claims hereto appended, and illustrated in the accompanying one-sheet drawing, of which, 4

Figure 3 is a view of the device in use, a part of the ink bottle being cut away to show the penetration of a pen point through the device;

Figure 4 is a perspective view of the device, inverted;

Figure 5 shows a slightly diiierent embodiment of the device, the main difference being the shape 5 0f the flange surrounding the upper end of the device; and,

Figure 6 is a plan view of the device looking directly at its lower end, and shows particularly the relative positions or" the slots and teats.

My invention consists primarily 1n a rubber guard half ovoid in shape and circular in cross- 'section. In the drawing this is represented as a whole by numeral I. The guard has an annular 5 shoulder 2 surrounding its upper end which is adapted to seat on the upper edge of the neck of the bottle or ink well 3, and to thus support the guard therein.

At its lower end the guard I is, provided with four spaced teats 5 which are in horizontal align- .5 ment, and which are preferably spaced 90 from each other. The lower end is also provided with vertical slots 6, i, 8 and 9. In length these slots extend less than half the total vertical length of the guard. The slots are preferably spaced as 10 shown in Fig. 6, and run between the teats 5. A cap 9, having a hole H] which is slightly less in diameter than the interior of the upper end of the guard I, is provided for the bottle or ink well.

It has the usual sealing groove H, and when the 16 guard i is in position in the neck of the bottle and the top 5 is screwed down tightly on the bottle, the annular groove I l tightly seals the shoulder 2 against the bottle neck.

As shown in Fig. 3 the edge of the perforation go lit in the bottle cap 9 prevents a pen staff I2 from coming in contact with the walls of the guard, and hence prevents ink from getting on the stafi.

To facilitate the handling of ink in bottles prepared for sale, an ordinary washer I3 is provided 5 with the device, although it is not an essential element of the invention. The same is true of the metal guard l4 shown in Fig. 5. This guard i4 is formed with an annular shoulder which may be made of a size to fit any bottle, and is equipped 30 with a downwardly projecting frame which fits inside the guard I, and which is open at its lower end, as at Hi. This is merely an auxiliary guard to prevent the pen staff I2 from projecting through the guard i and thus being immersed in 5 the ink below; the opening l5 will, of course, allow passage of the pen point therethrough.

In operation the washer I3 is removed and the cap 9 replaced on the bottle 3. The pen enters through the hole It] in the cap, and is simply 40 pushed through the lower end of the guard l, the slots 6, I, 8 and 9 permitting the lowernend of the guard to be deformed, as shown in Fig. 3. The pen is thus allowed to enter the ink in the bottle and when withdrawn the excess ink is removed from the pen by the segments of the lower portion of the guard, due to the inherent tendency of the rubber to assume its normal position, as shown in Figs. 1, 2 and 4.

The teats 5 serve to hold an accumulation of ink on the nether surface of the guard by forming sufficiently small unit areas that the surface tension of the ink holds the ink thereon. After the ink has accumulated on the lower end of the device it is no longer necessary to insert the pen point into the ink in the bottle, the accumulation on the lower end of the guard I being sufficient to thoroughly wet the pen with ink a number of times.

When used on a deep bottle, it is only necessary to invert the bottle before dipping the pen. The inversion of the bottle allows the ink to fill the neck of the bottle, and when the bottle is again righted a considerable quantity of ink runs down the outside of the guard and is held on the lower end of the guard as previously explained. The pen may then be simply pushed through the opening formed by the slots and will be wet thoroughly with writing fluid. It will be evident that the number of the teats 5, as well as the number and length of the slots 6, l, 8 and 9, may be varied without changing the principle of the invention.

On a wide neck bottle I prefer to form the annular shoulder on the guard I as shown at In. in Fig. 5. This shoulder is tightly held between the upper edge of the bottle and the groove H of the cap 9, and thus supports the cup-like portion at any desired point within the bottle neck. It is evident that there would be no invention in locating the cup-like portion of the guard l off-center with relation to the circular shoulder 2a, and I contemplate so locating the said cup-like portion to fit any bottles at present on the market. In so doing, it would, of course, be necessary to locate the perforation H3 in the cap 9 to align with the cup-like portion of the uard.

By making the wall of the extreme lower end of the device thicker than the side Walls, as at 4, the separate segments defined by the slots 6, 1, 8 and 9 are prevented from curling upward into the interior of the guard itself. When the bottle is inverted ink is prevented from penetrating the slots by the simple pressure exerted on the segments of the device by the weight of the fluid. Due to the inherent tendency of the rubber material to assume its normal shape the slots are normally held tightly closed, and thus prevent evaporation of ink through the bottle neck.

Having thus described the invention, what I claim and desire to secure by Letters Patent is:

1. A device of the class described comprising a cup-like guard made of rubber, its upper end being encircled by an outstanding annular shoulder for supporting the device within the upper end of an ink bottle or ink well, its lower end being formed in a plurality of integral segments which act to normally close said lower end, but which under pressure may be deformed to provide a passage through said lower end; and a plurality of spaced protruding teats on the nether surface of the lower end of the guard located sufficiently close together that the surface tension of the ink is enabled to hold an accumulation of ink on the nether surface of the guard.

2. The combination with a substantially cuplike resilient container closure having its lower end divided into flexible longitudinal segments and adapted to be suspended in the open end of a container, its upper rim closing the opening in the container, of: a plurality of spaced protuberances on the nether surface of the lower segmented end of said closure so spaced as to form sufiiciently small surface unit areas thereon that the surface tension of a liquid is sufficient to hold an accumulation of the liquid on said nether surface.
