6 Claims. (Cl. 222-478) This invention which relates generally to vessels from which light viscosity liquids, such as water, aqueous beverages, etc., are to be poured, is concerned primarily with means for control of the liquid in its flowing movement out of the mouth of the vessel and for preventing after-drip therefrom. The kinds of vessels to which my invention is applicable are manypitchers, bowls, and decanters, just to mention a few. In the ensuing description the term decanter will be used as a designation for all such vessels.

More particularly the control means of this lnvention is carried by a lid which overlies the decanter mouth which is uniplanar in that the top face of its lip is continuous and unbroken throughout its periphery. Furthermore, in many such decanters the mouth is relatively wide, its circular lip at the top being described by a large radius which assures a uniform curvature at every point. Such a decanter is commonly produced at the present time for the lower bowl of a vacuum coffee maker according to the Cory Patent No. 2,359,405 of October 3, 1944. A distinguishing characteristic of such a lower bowl is that it admits of no pouring spout being formed at its top, so that, when tilted to permit out-flow of coffee therefrom, there is little or no control over the moving fluid therefrom and no prevention of after-drip at the conclusion of each such pouring operation.

The control means utilized for a decanter of this general description requires no modification of or addition to the decanter itself. Instead, it is carried by the 11d which is commonly associated with and mounted upon the decanter so as to provide normally a closure for its wide open mouth. The control means depends from the under side of the lid which may remain closed during each pouring operation, the control means then lying in the path of the out-flowing liquid so as to act thereupon in the special manner hereinafter set forth in detail.

In the accompanying drawings certain preferred embodiments of this invention are illustrated in the manner following:

States Patent 0 Referring first to Figs. 1-4, there is here shown a decanter D in the general form of a bowl whose walls converge near the top to provide a neck 11 around which is secured a collar 12. Just above the neck the decanter is provided with a wide open mouth which is bordered by an outturned lip 15 which, in the construction illustrated, is circular in contour. A distinguishing feature of this lip is that its top face is uniplanar, i. e. it is devoid of any irregularities or breaks in its continuity such for example as by a pouring spout which is a feature common to most pouring vessels.

The collar 12 comprises a fitting 17 having a pair of upwardly extended spaced tongues 18 adapted to receive between them an car 19 projecting laterally from a lid L which surmounts the decanter. As by a pin 20 which traverses the ear with its opposite ends supported by the tongues 18, the lid is hingedly mounted with capacity for upwardly swinging movement through more than to a position of rest against a handle H that is fixedly secured to the decanter through the medium of its collar 12. In its open position (see Fig. 1) the lid affords unrestricted access to the wide open mouth of the decanter. In its closed position the lid presents a nearly annular face 22, adjacent its periphery, in seating relation to the uniplanar top face of the decanter lip 15 to coact therewith in the manner now to be explained.

The lid contour is generally circular with an upward slope toward its center so as to provide therebelow a shallow chamber which is disposed mostly above the decanter lip 15. Depending from the lid is a circular wall 2 5 which borders the inside of its contact face 22 and extends slightly into the decanter mouth close to the inner edge of its lip 15. At a point opposite the car 19 the wall 25 is broken to provide an out-flow opening 0 bordered by spaced radial walls 26 which join with the circular wall 25. The radial walls 26 along the top also join with the lid which is somewhat elevated between these walls in the form of a, deck 28 which extends radially inwardly to merge with the generally convex contour (in vertical cross section) of the lid.

The space between the radial Walls 26 defines, in effect, a radial passageway 12 communicating with the out-flow opening 0. In response to manipulation of the handle H whereby the decanter is tilted, liquid which is poured therefrom flows across the lip 15 and, with but very little care, may be so controlled as to confine itself to the space between the radial walls. For this purpose I provide a radially extending guiding rib 29 which depends from the deck 28 between the walls 26 medially thereof. This rib which starts near the center of the lid inclines downwardly at a then is rounded at b to proceed upwardly for termination in a ledge c which overlies the lip 15, either resting thereupon or lying close thereto.

The lid when so constructed and combined with a decanter of the kind described, provides a control means whereby liquid poured from the decanter in a proper manner is caused to flow across the lip 15 within the relatively narrow space defined by the radial Walls 26. To obtain such a control in the out-flow of the liquid I rely upon its property of surface tension which draws it toward the adjacent surfaces. The rib 29 provides two such surfaces medially of the passageway p which ends in the out-flow opening 0. The presence of this rib provides a capillary attraction which confines a normally out-flowing stream to the narrow limits of this passageway so that there will be little tendency for the liquid to spread when crossing the lip 15. The presence of the radial walls 26 along the sides of the passageway p acts also as a deterrent to prevent lateral spreading of the moving liquid in case the decanter be tilted to the point of augmenting its flow beyond the capillarity capacity of the guiding rib. Furthermore, at the conclusion of the pouring operation, any liquid remaining on the lip will be drawn back by the adjacent ends of the walls 26 and rib 29 to remain inwardly of the lip so as to avoid any after-drip therefrom. This is a par ticularly desirable result, since after-drip is usually encountered in a decanter having a wide mouth terminating in a uniplanar lip.

Referring now to Figs. -9, there is here shown a decanter D in the general form of a bowlwhose walls example as by a pouring spout which is a feature common.

to most pouring vessels.

The collar 52 comprises a fitting 57 having a pair of upwardly extended spaced tongues Sit-adapted to receive between them an ear 59 projecting laterally from alid L which surmounts the decanter. As by a pin 60 which traverses the ear, with its opposite ends supported by the tongues 58, the lid is hingedly mounted with capacity for upwardly swinging movement through more than 90 to a position of rest against a handle H that is fixedly secured to the decanter through the medium of its collar 52. In its open position (see Fig. 5) the lid affords unrestricted access to the wide open mouth of the decanter. In its closed position the lid presents a nearly annular contact face 62, adjacent its periphery, in seating relation to the uniplanar top face of the decanter lip 55 to coact therewith in the manner now to be explained.

The lid contour is generally circular with an upward slope toward its center so as to provide therebelow a shallow chamber which is disposed mostly above the decanter lip 55. Depending from the lid is a. circular Wall 65 which borders the inside of its contact face 62 and extends slightly into the decanter mouth close to the inner edge of its lip 55.

At a point opposite the car 59 the wall 65 is chorded at 66 so as to be spaced away from the inner edge of the decanter lip 55 at that point (see Fig. 6). Adjacent the chord wall 66 the lid L extends outwardly over and beyond the outer edge of the decanterlip 55 to form an eave 67. The under side of this cave which remains spaced from the lip 55 joins with the chord wall 66 and also with a pair of spaced radial walls 68 which together define an out-flow opening 0'. In effect the chord wall 66 constitutes a dam under which the liquid in the decanter must pass when it is poured.

The lid when so constructed and combined with a decanter of the kind described provides a control means whereby liquid poured from the decanter in a proper manner is caused to flow through the out-flow opening 0' defined by the lip 55, cave 67, and radial walls 68.

To obtain the desired control in the out-flow of the liquid I utilize its property of surface tension which causes the liquid to be drawn to the adjacent surfaces. The chord Wall 66 and the cave 67 provide a surface to which the out-flowing liquid is drawn as by capillary attraction with the result that a constant, well-defined stream is produced which, to a considerable degree, is drawn upwardly and outwardly past the lip 55 by the capillary attraction of the cave 67 before falling away therefrom in response to gravity (see Fig. 9). This has the effect of reducing the amount and weight of liquid which comes in contact with the decanter lip '55 and consequently reduces drip at that point. Furthermore, at the conclusion of the pouring operation any liquid remaining in the out-flow opening 0 is drawn back by the downwardly and rearwardly inclined under surface of the cave to the chord wall from whence it drips into the decanter, thus eliminating after-drip on the outside.

The two forms of my invention herein described both employ the same fundamental means to induce capillary attraction. In both constructions a portion of the lid depends into the path of the out-flowing liquid so as to draw the out-flowing liquid and guide it through the opening provided therefor. This same depending lid portion, also through the medium of capillary attraction, causes liquid to be drawn back into the decanter at the conclusion of the pouring operation thus reducing after-drip.

The present embodiments are to be considered in all respects as illustrative and not restrictive, the scope of my invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
