'Ihis invention relates to ink bottles in which is a small well which can be iilled with ink by inverting the bottle.` The proposals that have already been made to pro-vide small wells in ink bottles have variousobjections` to or limitations on their use, among the chief of which are: They are not adaptable to a standard ink bottle but require a specially formed bottle, and/or they are not removablefrom the bottle as a unit, and/or they require a special position of the bottle when it istilte'd` for filling which involves time or difficulty for the user to locate, and/or the ink does not fill ordinarily to the top of the well, and/or the material of which they are made is aifected physically or chemicallyby the ink, and/or they are easily deformed or broken, and/or they permit ink to smear the bottom of the barrel of a fountain penlwhile it is being iilled, and/or they e do not permit the straight dipping of pens of dif- 20 ferent `size andshape. The foregoing defects, among others, found in such devices led me to engineering research in this eld and the present invention `has for its objects, among others, lto provide a device of this type in which the cap of the ink bottle forms: part of the improved device, to position the well in the neck of the ink bottle with the top of the well at or above the top of the bottle, to provide an upper auxiliary capV for the Well which may be of a color that indicates the color ofthe ink in the bottle and maybe `contrasted in color with that of the remainder of the can, to provide locking means to prevent the cap from unscrewing from the bottle, to provide a structure that permits the well to be quickly filled when the bottle is turned upside down and in any direction, to provide a structure that permits the last drop of ink in the bottle to flow into the well,\to provide a restfor the bottom endI of i a fountain pen barrel which prevents smearing of ink on the barrel particularly at or near the usual linger grip, to provide a well that permits the ready dipping and filling of a fountain pen having a pen point of any size, to provide apertures at the top of the well, to provide an aperture at the bottom of the well, to provide a valve at the bottom of the Well including a steel ball that quickly runs away from the bottom aperture when the bottle is tilted and runs around o the well to set up air currentsin the well that facilitate the escape of air and the rapid flow of ink into the well, to provide such a device that adds little or no top-heaviness to the ink bottle, to provide a device of plastic moldable material, and to provide a device susceptible of W manufacturing cost. Other objects will appear as the description proceeds.

A standard ink bottle 20 has a cylindrical upwardly extending neck 2| provided with standard screwthreads 22 on the outer wall. A cap 23 has an outer cylindrical depending flange 24 which is internally threaded to engage the screwthreads 45 22. The cap 23 has an annular upward cylindrical flange 25"which has external screwthreads 26 and on the inner wall a plurality of Widely spaced apart inward projections 2l. A cupshaped Well 28 has a maximum diameter such as to provide 50 a substantial annular space 29 between it and the inner wall of the flange 25, between the projections 2l, suliicient to permit the ready flow of liquid or air therethru. The body of the well 28 is also similarly spaced from the inner wall 55 of the neck 2l of the bottle. On the outer wall of the top of the well 23 are `a plurality of outward projections 3l, spaced similarly to the inward projections 2l and adapted to rest thereon and to support the well 28. In the modication shown in Figures 4, 6, and 7 the projections 21 and 3l are molded together integrally. In the form shown in Figure 2 the tops of the projections 27 and the bottoms of the projections 3l may have la radially interlocking t against relative ro-tation. The top of the well 28 and each projection 3l may have a vertical recess 32 for receiving a pen point 33 projecting from a fountain pen barrel 34. In the form shown in Figure 2 upward projections 35 hold the top of the well spaced enough from the auxiliary cap 36 for the free flow of ink or air. The auxiliary cap t6 has an internally threaded peripheral cylindrical ange 3'.' for screwingT on the threads 2t of the flange 25 and is extern-ally ribbed or knurled for facile manual rotation. A crescent-shaped rib 38 concentric with the recess 32 may be provided as a rest for the bottom of a fountain pen barrel 34 to keep it above the top of the well 28 when lling the fountain pen 34. In the form shown in Figure fi spacing projections 35 are not needed. In the form shown in Figure 3 in lieu of the projections 3l is `an annular projection 39 having perforations 4l, the total area of which is considerably more than that of the solid wall of the projection 39 to permit the free ilow of liquid or air therethru. Small nibs or spacers 42 may keep the top of the well 28, when inverted, below the auxiliary cap 36 to permit the free iiow of liquid or air thru the holes 4 I.

The bottom of the well 28 has a downward extension to provide an inside bottom recess 43.

which has an opening 44 at the bottom thru the well 28. A spherical ball 45 normally sits in the recess 43 and closes the opening 44. The recess 43 is so formed that its side walls prevent lateral displacement of the ball 45 from the opening 44, especially when pushed by a pen point. The walls of the recess 43 may flare outwardly and upwardly so that the ball 45 is free to roll into the well 28 when it is tilted. The acceleration of gravity causes the ball 45 to roll swiftly about the inside of the well and to set up swirls in the confined air which accelerate the flow of ink from the bottle 2B into the well 28 while the yauxiliary cap 36 is secure over the well and to instantly close the aperture 44 when the bottle is set down erect with the Well 28 full of ink.

Referring to Figures 8, 9, 10, and l1, a well 46 may be molded integrally at the top by means of four equally spaced relatively narrow bridges G1 With the top annular flange 25 of the cap 23, said bridges 41 spacing the bottom of the cap 36 from the top of the well 46 to permit the free flow of ink or air thru the arcuate spaces 48 which are lcontinuations of the annular space between the well 46 and the neck 2l of the ink b ottle. On the inner wall of one or more of the bridges 41 and of the well 46 may be formed a trough-like penpoint holder 49 the top of which rises above the top of the well 46 at 5l to keep the bottom of a fountain-pen barrel 34, while resting thereon, out of the ink in the well.

Referring to Figure ll a lock may be provided to prevent turning of the cap 24 on the neck 2l of the bottle when the cap 36 is being turned off, consisting of interengaging vertically separated lateral projections on the lowermost threads 22 of the bottle and of the cap flange 24, which latter possesses sufcient elasticity to permit the projections to be forced over each other in securing the cap thereon initially.

Referring to'Figures 12, 13, and 14, an auxiliary cap 52, has a greater diameter than the cap 53 which screws on the neck 2l of the bottle 26. The top of the cap 53 has an upward annular flange 54 coextensive with the neck 2l and externally threaded to receive the internal threads of the depending flange of the auxiliary cap 52. Projecting inwardly from the flange 54 is an annular extension 55 the upper surface of which is inclined downwardly and inwardly and has formed in the bottom an annular groove 515 which tightly nts over the top of the neck 2l of the bottle. A well 5'5 has an outward and upward flare 5S which supports a plurality of equally spaced outward arms 59 which have depending members which rest on the extension 55, `and the bottom of the auxiliary cap 52 engages the tops of these arms 56. The top of the well 5l' is so spaced from the wall 54 of the cap and the extension 55 as to permit the free flow of ink or air over the top.

of the well 5l which may have four pen-point guides or holders 49, one near each arm 59.

Referring to Figure 15, the cap has an annular internally threaded cylindrical ange 6l threading on the neck ZI, an outward and upward flare 52 at the top which supports an eX- ternally threaded annular cylindrical flange 63 at the top, the threads of which receive the threads of an annular flange 64 depending from an auxiliary cap 65. A well 66 has the aperture 4t at the bottom over which lies the spherical ball 45 in a recess formed in the bottom of the well 66. The top 6l of the well 66 flares outwardly over the neck 2| to widen the Well appreciably at the top, and to form a supplemental rest 68 for the bottom of a fountain pen 34 when the ink in the top 67 has been consumed. A plurality of radial arms 69 project outwardly, have downwardly turned ends 'H which rest on an annular ledge 12 formed on the inner wall of the flange 63, and so space the well 6l from the cap 65 and the flange 63 to permit the free flow of ink or air around the well 6l and over the top thereof.

Another' modification is shown in Figures 16 and 17 in which a cap has an annular internally threaded ange 13 screwed on the neck 2l, a flat annular portion 'I4 overlying the neck 2l,A a depending annular lip 15 inside the neck 2l, an externally threaded cylindrical flange 16 having an annular ledge 11 on the inner wall, and an auxiliary cap 'i8 having an internally threaded cylindrical flange 'I9 screwed on the iiange 16. A well 3l has at the top four equally spa-ced inverted-U-shaped arms 82 which rest on the ledge T! and space the sides and top of the well 8! from the flange 76 and the auxiliary cap 1S to permit the free ilow of ink or air. The side walls of the well 8l are parallel and taper inwardly at the bottom in which is a recess having the aperture at the bottom closed by the spherical ball 45. Figure 17 shows the formation of the side walls to provide four vertical pockets 83 opening into the center, each pocket in cross-section being greater than half a circle and permitting the vertical introduction of a fountain pen point 33, the arms 82 providing stops for the bottom of the fountainpen barrel 34.
