4 Claims. (Cl. 222-490) This invention relates generally to a combination closure and dispensing device for receptacles,
The bottles heretofore known provided with drop counters have the disadvantage that their use requires a certain amount of skill so that when dispensing the contents of the container in the form of drops mistakes often occur which may have a harmful effect when medicinal liquids are dispensed.
This deficiency is eliminated by the present invention. This invention relates to a method of drawing-olf liquid from the container in metered or predetermined amounts and to a device for carrying out said method. The method according to the invention consists in that an excess pressure in the container is created by operative action, means being provided serving to close the orifice of the container, said excess pressure causing the issue of a predetermined quantity oi liquid out ofthe container. out the method is characterized in that the container is provided with means consisting of resiliently extensible material provided with at least one outlet opening, the outlet opening closing automatically in one position due to the inherent elasticity of the aforesaid means and being under the operative action of pressure means for the purpose of creating an excess pressure Within the container by operating the closure means, said excess pressure causing the issue of a predetermined quantity of liquid out of the container.
By Way of example several embodiments of suitable devices for carrying out the method are shown in the accompanying drawing in Which- Fig. 1 is a longitudinal section through the device according to the rst example of embodiment shown in the closed position and in connection with a partly illustrated bottle-shaped container, Fig. 2 the same device in the open position,
, Fig. 3 a second example of embodiment of the The device for carrying device also in the longitudinal section and in connection With a bottle-shaped container only partly shown,

Fig. 5 a longitudinal section through the device according to the third example of embodiment again in connection With a bottle-shaped container only partly shown, Fig. 6 a detail to Fig. 5 in side elevation,
Fig. 7 a longitudinal section through the device according to the fourth example of embodiment vice according to the fth example of embodi` ment,
Fig. 9 a side elevation of the device in connection With a bottle only partly shown,
Fig. l0 a longitudinal section through the device shown in Fig. 9 in the closed position and Fig. l1 the same device in the open position.
With the rst example of embodiment shown in Figs. l and 2 the device consists of a closure 'means adapted to be secured on the neck of a bottle 2 only (partly shown). The closure means in the form of a disk acts as a diaphragm 3 made from elastic extensible material, such as a rubber disk of circular shape. The diaphragm 3 is provided With an opening or orifice 4 `(Fig. 2) in its center, said opening or orifice, being normally closed in the non-tensioned position due to its inherent elasticity. The diaphragm 3 is arranged to extend across the mouth of the neck l of the bottle and is secured to the edge 5a by means of a sleeve 5. Said sleeve 5 is provided with 4an inside screw thread and is screwed on to the outside screw thread provided on the neck I. Over the sleeve 5 an axially displaceable cap B is arranged, said cap being prevented from rotating by the nose 6a which nose 6a is guided in a groove l provided on the circumference of the sleeve 5 and extending in the axial direction of the sleeve. The cap 5 is provided with a pressure piece 8 arranged centrally which pressure piece is axially pierced by a duct 9 and has a projection 8a on its end opposite to the neck I of the container. The pressure piece 8 is of such a length and has an end face positioned opposite projection 8a that it comes to lie in the position of rest above or on the upper surface of the diaphragm 3 shown in Fig. 1 without tensioning said diaphragm. lf, however, the cap 6 together with the aforesaid end face of the pressure piece 8 is axially displaced into the position shown in Fig. 2, the diaphragm 3 is tensioned causing the opening or orice 4 provided in the diaphragm 3 to register with the duct 9 of the pressure piece 8 Which has a sufciently large end face so as to be incapable of piercing the perforated diaphragm or disk 3.
To operate the device described, the bottle 2 is gripped and inclined to such an extent until the neck l is lled with liquid representing the contents of the bottle. Now the cap 6 is axially displaced from the closed position (Fig. 1), so that the end face of the pressure piece 8 will tension the diaphragm 3 more or less according to the amount of displacement. In this manner an excess pressure is created through the displaced diaphragm Within the bottle. Simultaneously the opening 4 of the diaphragm 3 is expanded and freed due to the tension and accordjing to the amount of tension. this openngor orice will have a smaller or larger diameter. At the same time an exactly metered quantity of liquid issues through the opening 4 due to the excess pressure. The calibration of the device can be carried out empirically. Depending on the rate of axial displacement the same amount of liquid issues in the form of drops on slow displacement or in the form of a liquid spray on rapid displacement. For the exact controlling of the quantity of liquid the cap nut 5 can be provided with a graduation with which e. g. the corresponding edge of the cap 6 co-operates.
Instead of a graduation the axial displace'- ment at the cap 6 can be limited by an adjustable stop IIJ (Fig. 3). Said stop is formed of a ring and has an inside screw thread so that the ring can be screwed on to a corresponding outside screw thread of the sleeve 5 and can thus be adjusted to various levels.
According to the alternative shown in Fig. 4 the cap 6' is rigidly connected with the sleeve 5 and serves for the reception of a pressure piece 8', said pressure piece being in its turn connected with the cap 6' for the axial displacement. The pressure piece B is provided with an outside screw thread so that it is adjustable in a threaded hole of the cap 5', said threaded hole being provided with a suitable inside screw thread.
With the examples of embodiment according to Figs. 5 and 6 the difference compared to the nist-described example of embodiment lies mainly in the fact that the sleeve 5 is connected with the cap 6 by means of a bayonet catch. For this purpose the sleeve 5 has a guidingslot Il (Fig. 6) which consists of two guiding parts running parallel to the axial direction and a connecting part running horizontally thereto. In said slot II the nose 6a of the cap 6 (Fig. 5) is guided so that the latter can be secured `at two different levels according to the bipartiteness of the slot I I.
The manipulation of the device according to the last-described example of embodiment takes place essentially in the same manner to that according to the first-described examples of embodiment with the difference only that the cap 6 or 6', respectively, is displaced according to its execution in one case against the stop I0, in another case by carrying out a combined sliding and rotary movement (Figs. 5 and 6) or according to Fig. 4 by the pressure piece 8' only being adjusted. In each case an excess pressure is created in the container, i. e. in the bottle I, and the closure orifice 3 is opened more or less.
A further example of embodiment is shown in Fig. '7. The neck I of the container 2 for liquid here only partly shown is provided with an outside beading I2, and the mouth of the neck is closed by a diaphragm 3 secured by means o1.' a sleeve I3. The sleeve I3 can e. g. be pressed of light metal and be so formed that at one end it Vgrips under the lower edge of a bottle edge I2 by means of a flange I3 and at the other end has a collar I3", said collar being adapted to guide a pressure means I4. The pressure means I4 is arranged co-axially to the bottle 2 and bears with one end against the diaphragm v3 and is axially pierced by a duct I5. With the numeral I6 a captted over the pressure means I4 of the sleeve I3 is designated, said cap consisting e. g. of rubber and closing the duct I5 at the end remote from the diaphragm 3 when not in use.
For use the pressure means `I4 is axially displaced towards the diaphragm 3 by pressure in the direction of the arrow P so that said diaphragm is tensioned and the opening in the centre of said diaphragm, which opening is closed when the diaphragm is not tensioned, is more or less opened. Simultaneously the rubber cap I6 over the pressure means I4 is also tensioned whereby an opening communicating with the mouth of the duct is freed and the contents of the bottle 2 can issue.
.A further example of embodiment shown in F1g. 8 is particularly suitable for the reception and dispensing of perfumes, such as eau de Cologne, etc. The difference compared with the examples of embodiment heretofore described lies inthe fact that the bottle 2 is arranged in a contamer composed of a sleeve Il essentially closed at one end and a bottom part I8 connected with said sleeve I'I by means of the screw thread I9. The closed end of the sleeve I'I has a semispherical shape and serves for the reception of a pressure means 20 having a duct 2I arranged coaxially with the bottle 2, and opening 22 in the semi-spherical closed end of the sleeve Il being arranged to correspond with the duct 2|. The pressure means mentioned is a hollow body adapted to nt into the semi-spherical closed end of the sleeve Il and is provided with a practically cylindrical extension 2d pierced by duct 2|, the inner end of said extension bearing against the diaphragm 3 of the bottle 2. The diaphragm 3 1s secured to the neck I of the bottle in a conventional manner, such as by means of a sleeve 23.
The bottle is axially displaceably arranged within the two-part container Il, IB. and a press button 24 in the bottom part IB of the container is inserted as a displacing means. For this purpose the bottom part I8 is provided with an annular rib I8 on which rib one edge 24 of the press button Z4 rests. Between the side wall of the bottom part I8 and the bottle 2 there is a hollow space 25 in which a compression spring 26 is arranged, said compression spring bearing at one end against the edge 24 and at the other end against the opposed limitation of the hollow space 25.
The operation of the last-described device is carried out in such a manner that a pressure is exerted on the press button 24 in the direction of the bottle 2 whereupon the bottle is displaced. By this movement the extension 20 of the pressure means 20 acts operatively on the diaphragm 3, thus causing said diaphragm to be tensioned and its orifice to be opened. At this moment a metered quantity of liquid corresponding to the excess pressure created issues out of the inside of the bottle. In order to be able to check the contents of the bottle 2 capsule part I'I has an oblong opening 2B.
The last example of embodiment is shown in Figs. 9-11. On a bottle neck 2l provided with a screw thread 28 a cap nut 29 is secured, said cap nut being adapted to act as a guiding and stop means for a pressure means 3D provided with an annular collar 32. Said pressure means is of an elongated shape and bears with one end against a diaphragm 3| which diaphragm is stretched and extends across the mouth of the neck and is there secured by means of a screw cap 29. The lunger pressure means 30 through which extends a duct 30' is axially displaceable in such a manner that by its displacement the diaphragm 3l is tensioned and a normally closed orifice 3l' of .the diaphragm aligned with and communicating with the duct 30 is exposed and freed,
thus affording for the liquid to escape from the inside of the bottle through said orice and duct. It will be realized that the end face of the plunger means 30 is smaller in diameter or extent than that of the open end of the neck 21, but considerably larger than the diameter of the orifice 3l when diaphragm 3l is deformed and partly displaced within the open end of said bottle or container neck 21 (compare Figs. 10 and 1l).
In use the last-described device can be operated in a simple manner by means of one hand only.
The device according to the examples of enibodiment described enables a faultless and ex tremely exact metering of liquids without parn ticular skill or attention being required.
What I claim and wish to secure by Letters Patent is:
l. A container having an opening for dispensing a liquid therefrom comprising means of elastic, extensible material placed across said opening, said means being provided with an orifice remaining normally closed in the position of rest of said means due to its inherent elasticity, a sleeve securing said elastic means to the neck of the container and extending over the neck of the container for securement thereto, a cap, and pressure means on said cap, said pressure means having a duct passing therethrough and arranged coaxially to the orifice of said elastic means and resting against said elastic means from the outside thereof, and means on said cap and said sleeve in the form of a nose and a groove parallel to the axis of the container to prevent rotation.
