I I I 20 Inventors,- WWm V W /w Patented Oct. 20, 1936 PATENT OFFICE LIQUID CON TAHWER Sophie Scheyer, born von Pezachowicz, and Sandro Arcari, Munich, Germany Application April 24, 1935, Serial No. 18,012 In Germany April 24, 1934 7 Claims.

This invention relates to liquid containers having pouring means for regulating the outflow of liquid, for example, for preventing the escape of drops after a liquid has been poured out or for dispensing the liquid from the container.

Liquid containers in which a spout has pouring means provided with a capillary groove widening or enlarging in the direction in which pouring occurs are already known.

The object of the invention is to provide a liquid container'with improved pouring means of this type by making the uppermost part of the groove substantially semi-circular from inside to outside of the pouring means. The inner end of the capillary groove adjacent the semi-circular part is made deeper according to the invention than the outer end of the enlarged capillary groove.

The enlarging capillary groove in the pouring means according to the invention terminates at the outer end in an enlargement with the formation of corners, for example, a hemispherical or similar hollow space disposed in the pouring means.

Further, according to the invention the groove is funnel-shaped and is substantially enlarged in dove-tail fashion at the front end disposed in the lip of the-spout.

A further important feature of the present in- 00 vention is that another groove is provided above the groove which enlarges in the pouring direction, said further groove becoming narrower in a direction opposite to that of the'first-mentioned groove in the pouring means.

35 According to another feature of the invention an insert is provided for liquid containers not provided with pouring means, for example, for bottles for containing chemicals or the like, such insert having pouring means according to any one 40 of the embodiments of the invention.

Further features of the invention will be hereinafter referred to with reference to the accompanying drawings in which several forms of the invention are illustrated by way of example.

45 Fig. 1 is a front elevation of the spout of a can.

Fig. 2 is a longitudinal section taken on the line 11-11 of Fig. 3.

Fig. 3 is cross-sectional view taken on the line 50 IIIIII of Fig. 2.

Fig. 4 shows the edge of the spout on an enlarged scale.

Fig. 5 illustrates the method of forming the interior channel prior to becoming set, the fig- 55 ure being a section on the line A-B of Fig. 2.

Fig. 6 shows the shape after setting has occurred, the figure being a section on the line A-B of Fig. 2. Figure 6a. is a cross-sectional view taken on the line CD of Figure 2 on a larger scale. 5

Fig. 7 shows a modification of the invention applied to a measuring cylinder.

Fig. 8 shows the embodiment according to Fig.

7 in section, it being clearly indicated that the shape of the capillary groove at the highest part 10 in the pouring means is substantially semicircular in an outwardly extending direction.

Fig. 9 shows a side elevation of a bottle partly in section and embodyinga further feature of the invention. 15

Fig. 10 is a plan view of the bottle according to Fig. 9 and clearly showing how two superposed grooves enlarge in opposite directions.

Fig. 11 is a front view of the bottle according to Fi 9. 0

Fig. 12 shows a bottle serving, for example, for containing chemicals, an insert having a groove according to the invention being fitted in the neck of the bottle.

Fig. 13 shows a front elevation of the bottle and 25 pouring means according to Fig. 12.

A groove 3 of funnel shape is provided in the under part of a spout I and widens outwardly,

i. e. in the direction in which pouring of the liquid occurs. In the preferably thickened forward end 4 of the under part of the spout 2 the groove 3 is enlarged as indicated at 5. The groove 3 as illustrated in cross section in Fig. 6 throughout the rear part has sharp corners and is of U- shape. Its front part is enlarged in dove-tail fashion so that the base 6 is larger than the distance of the crown 1, and the funnel-like configuration of the groove suddenly terminates at the forward part of the lip in an enlargement, the walls 8 of the groove no longer being vertical but in consequence of the dove-tail formation being inclined laterally or undercut as shown at 9 in Figures 4, 6a and '7. The base line 6 is so formed that it follows as close as possible the outer edge II of the lip of the spout. In order to obtain a particularly sharp cornered groove it is preferable to make it oversized when the article is in the soft state so that the side parts ID are deeper but when the container sets or becomes hard the side parts become adjusted and receive the desired shape shown in Fig. 6.

In Fig. 9 a further modification of the invention is illustrated and is particularly adapted for the discharge of very fine doses from the bottle. In such containers for regulating the out- In order to attain this the liquid must be suprplied for delivery as drops in the smallest quan-' tities. In consequence a special supply'rgroove must be provided which is smaller than the complete outflow orifice proper but whichflisllarger than the groove in order to overcbme the adhesion thereof. Preferably thetwo groovesyare' pro-2, ,1 vided above one another so as to beiof stepped'l. formation in cross section. The groove ,for the,

backflow of the drops is deeper than the other upper groove which is wider in cross section than the former. That is, the upper groove which does not extend to the end of the bottle neck, is funnel-shaped and only permits the supply of liqe uids in very small or minute quantities.

In known manner'the pouring lip I, Fig. 9, is provided on the neck of the bottle and the groove 3 for the back-flow of the drops is cut or pressed in the lip. The groove shown in Fig. 9, 10 or 11 terminates at the bottom-of the bottle neck l3 in a flat mouth M. The groove I l/3 enlarges outwardly like a. funnel. Thisfunnel-shaped groove can be made more effective at the lip I in a particularly favourable manner by providing above it a second groove Hi. This groove |5is also of funnel-shape but it narrows in the direction in which pouring occurs. This is clearly shown in Fig. 10. The groove l 5 is located above the groove 3 so that both grooves have thestepped forma-- tion illustrated in front View in Fig. 11.

A particularly advantageous arrangement is illustrated in Figs. 12 and 13 in which an insert is provided for containers or bottles which are not themselves provided with pouring means. Ordinary bottles without pouring means are used for containing liquids, for example in chemists shops, laboratories and the like. With such containers .it is possible to prevent the escape of drops after a pouring operation by providing an insert in the form of a stopper in the neck thereof, said stopper having a; capillary groove constructed as hereinbefore described. Such a stopper, apart from preventing the escape of drops, affords the further advantage: that by properly tilting the container a predetermined number of drops can be discharged-slowly and uniformly. V

Figs. 12 and 13 illustrate how the tubular stopper I1 is inserted in the neck "5 of a bottle 20. In the caseof ground bottles the stopper can be ground on its outer surface and may be made conical. It may even .be cemented in the neck of the bottle should this be necessary. The tubular stopper l I has a mouth 4 which is ground flat at the front as indicated at l8. This part terminates the sharp cornered groove 3 which,is rectangular in cross section and which enlarges ,Fayence, metal and the like. that the device according to the invention is outwardly in funnel-shape. This groove can be formed in any desired manner. The mouth of the groove is enlarged at its outer end 5 in funnel-shape. The tubular insert can be closed by a stopper. It may also be made completely closed except for a spout shaped mouth 4 in which case a closure stopper is not required.

Fig. 12 clearly shows that the highest part of the groove is substantially semi-circular in shape in the direction in which pouring occurs.

The liquid pouring means having a capillary groove shaped according to the invention can be provided 'in all liquid containers made of any material such as glass, porcelain, whiteware, It has been shown particularly suitable for delivering drops of'uni- 'form size or doses of lighter or'heavier liquid as well as for preventing the escape of lighter or heavier liquid from a container after a'pouring operation. 7
