Germany August 28, 1937 zzasvs e claims. (ci. ca -a1) the end of the spout and is held in the outside. groove is drawn through the opening into the\ inner groove.
The outside groove, applied accor ng to my invention, in connection with the ope g, forms the shortest way possible from the spot where the drop forms to the interior groove. Therefore even larger drops are drawn back with certainty, and this drawing back process already takes place if the vessel is only slightly turned back from the pouring position.'
Furthermore, my invention has the'advantage that the grooves serving for the holding and drawing back 'of the drop are open, therefore theycan be easily cleaned. The wall of the end of the spout itself maintains its full thickness, and thus its resistance against being broken is not diminished by applying myinvention.
The accompanying drawings illustrate the application of my invention to two spouts of difi ferent constructions, both made of ceramic material e.A g. china. The spouts are shown: in Figs. 1 and 6 as vertical sections, in Figs; 2 and 7 as side views, in Figs. 3 and 8 as front views, in Figs. 4 and 9 as bottom views, and in Figs. 5 and as top views. Y
In the innerside of the interior of the spout a (Figa, 1-5) there is provided an inner groove b which" merges near its outer end by an opening o r aperture c into the gorge d of the downwardly buiged end of the lip of the spout at a point below the pouring edge g of the lip.
In the underside of the lip of the spoutthere is provided a longitudinal open outer groove e which, by means of the opening c, is in horizontai communication with the inner groove b.
After the pouring of the fluid, there remains at the underside of the pouring edge or lip f a drip drop which is held by th-e outside groove e owing to the action of surface tension, and is completely drawn into the groove e. If the drop is large. the part of it which hangs downward out of the groove is prevented from falling down by the surface tension or cohercncy of the fluid operating over a considerable perimeter. In any case, the drop hanging in or at the outside groove e is held by the opening c in the path of the back flow of fluid in the inner groove b returning, after the action of pouring, down the spout. The surface tension of the fluid in the passages e-o-b is strong enough to sustain the drop hanging outside the spout and caus-e it to be drawn back into the spout even when the vessel is only slightly brought back into vertical position, because thestructure operates substantially wholly by surface tension rather than by gravity.
In Figs. 5-10. there is shown at the interior I of the spout near `its mouth Va groove b. At the end of the spout and at the underside of the pouring lip f there is cut an outer groove e. The inner groove b and outer groove e are in communication with one another Aby the opening or passage c. In this modiflcation the end of the spout is not bulged down into a drooping lip as in Figs. 1 and 2 but is continued substantially horizontally to the end of thespout (as shown in Fig. 7). Therefore the device which serves for drawing back the drip drop canbe applied without material alteration of the usual spout forms.
The outer groove e is considerably prolonged towards the vessel, so that it merges at the opening c into the inner groove b below the point J',
where the surface of the lip of the spout turns downward. In view thereof, and because of the end of the lip having a surface of relatively slight curvature. the remaining d rop which forms at f after the pouring of the iiuid ceases to maintain its tear-drop form; the drop tends to wet and spread over said lip surface and ,to run along the outer groove e as a thread of liquid, to the opening c, which communicates with the inner groove b, from which the liquid flows down inside the spout. entrained by the back flow of liquid in the spout. f
In this way the remainder of the liquid which returns down the spout after pouring is prevented from running down theoutside surface of the spout and from falling as a drop. The remainder of the liquid is drawn back immedi-` ately after the pouring is finished, and even before the vessel is brought back into a vertical position. Thus the danger of dripping is avoided irrespective of how the vessel may be handled.
Iclaim: Y
1. A spout for pouring vessels comprising an open outer groove on the pouring lip end and on the undersideof the spout, said outer groove being provided and extending in a horizontai plane, a passage extending through the spout from the inner end of the outer groove to the inside of the spout, and an inner groove on the inside surface of the spout in communication with the passage by means of the outer end of the inner groove, the spout terminating in a fiat curve and the outer groove being extended through the wall of the spout and ldown toward the vessel terminating in the downwardly extending wall of the spout.
2. Non drip spout for pouringvessels especially of ceramic ware comprising a spoutrlip and a pouring edge in which the under face of the spout lip mately horizontally lirom the front face 01Ev the lip close below the pouring edge of the lip, said groove communicating through laiull circumference aperture with the inner wall of the spout and said groove and daperture being of cross-` sectional dimension for maintaining eiective surface tension in the liquidrof the drip drop.
3. Non drip spout for pouring vessels especially of ceramic ware comprising aspout lip and a pouring edge in which the under face of the has a groove therein extending approxi-v y below thepouring spout lip has a groove therein extending approximately'horizontally from the front face of the lip close below the pouring edge of the lip, said groove communicating through a full circumference aperture with a groove extending downwardly in the inner Wall of the spout from a point near the pouring edge, said first-mentioned groove and aperture being of cross-sec- 'tional dimension for maintaining eective surface tension in the liquid of the drip drop.
' 4. Non drip spout according to claim 2 having an area of relatively slight curvature at the front of the pouring lip above `and around the 1 end oi. the groove in the under face of the lip.
wNon drip spout according to claim 3 having anareaA of relatively slight curvature at the front of the pouring lip above and around the end of the groove in the under face of the lip.
6. Non drip\spout according to claim 3 in which the groove in the inner wall ci the spout merges smoothly into the aperture at a point edge of the ip.
