Description
1. 1. 55305 MEASURING DEVICE FOR LIQUID PRODUCTS IN BOTTLES OR LIKE CONTAINERS The present invention relates to the packaging 5. of liquid products the volume of which must be measured when using the product so that an appropriate measure of the product is employed.
In this respect, it is convenient to have available a measuring device which may be incorp-10. orated in the neck of the bottle containing the liquid products or, better still, which is an integral part of the packaging, for example is unitary with the bottle cap.
In this respect, there is disclosed in the 15. German patent No. 1 202 672 a measuring device for inserting in the neck of a bottle and comprising a measuring compartment which is filled upon inversion of the bottle and a reserve compartment which is fed by the measuring compartment when the bottle is put 20. back into its normal position and communicates with the outlet orifice of the bottle, the said two compartments having axes parallel to the axis of the bottle and being separate, the measuring compartment comprising two orifices communicating with the 25. interior of the bottle, the first orifice being in the vicinity of its outlet orifice for filling and the second orifice being close to the opposite end of this compartment for discharging air in the course 2. of this filling.
When the liquid reaches the level of this second orifice, the filling stops, apart from the arrival of an additional amount of liquid termed 5. "free liquid" the volume of which is a function of a number of variables, such as the specific weight of the liquid and the extent of the filling of the bottle. Although this free liquid re-enters the bottle when the bottle is put back into its normal 10. position owing to the depression (partial vacuum) prevailing therein, this measuring device results in a lack of precision in the measurement which cannot be considerd negligable.
Indeed, this measurement depends on the 15. inclination of the axis of the measuring compartment relative to the vertical and it is only when these two axes are strictly parallel that precise measurement is provided.
The present invention aims to provide a 20. measuring device of greater accuracy and also which is capable of being manufactured simply and cheaply.
The present invention provides a measuring device of the aforementioned type, wherein the second orifice of the measuring compartment is 25. disposed at the level of the connection of the two compartments in a part common to the latter and is arranged in such manner as to act as an overflow for the reserve compartment which is arranged for this purpose to have an appropriate capacity relative to the measuring compartment and which thus perfects 30. 3. the measuring achieved in the measuring compartment.
The invention may be put into practice in various ways and one specific embodiment and a modification thereof will be described by way of 5· example to illustrate the invention with reference to the accompanying drawings, in which:- Figures la, lb and lc diagrammatically illustrate a measuring device according to the present invention in three stages of its operation; 10· Figures 2 and 3 are axial sectional views of two elements constituting, by their assembly, a practical embodiment of a measuring device according to the present invention; Figures 4 and 5 are respectively 15. cross-sectional views taken along lines 4-4 and 5-5 of Figures 2 and 3; Figure 6 is a partial view of a modification of the element illustrated in Figure 3; Figures 7 and 8 are perspective views 20. respectively corresponding to Figures 2 and 3 of the embodiment shown therein; and Figure 9 is a perspective view of the embodiment of the measuring device according to the present invention shown in Figures 7 and 8 after 25. assembly of these two elements.
The description of the principle and mode of operation of the measuring device will first of all be described by reference to Figures la, lb and lc. The measuring device is generally designated by the reference character D and is adapted to be inserted 30. 4. in the neck of a bottle F, for which, at the same time, it constitutes the cap.
The device D comprises a planar cover 1 rigid or integral with a skirt 2, the assembly affording a 5· cap for the neck of the bottle. A first tubular element or tube 3 which extends from its upper or cap end away from the cover 1 (with which it is rigid or integral) down the neck of the bottle. The tube 3 is connected at its bottom or bottle end by 10· an inclined wall 4 to the upper or cap end of a second tubular element or tube 5 of smaller section than the tube 3 which tube 5 is closed at its opposite bottom or bottle end. The tube 3 is divided by a partition wall 6 which extends from the 15. cover 1 to a point just beyond the wall 4 and thus just within the tube 5. The partition wall 6 divides the tube 3 into a measuring compartment A and a communication passage 6a. Compartment A is offset relative to the tube 5 and the communication passage 20. 6a is generally in line with the tube 5. Thus the tube 5 constitutes a reserve or storage compartment B which communicates, on one hand, with the compartment A at the inner, bottom or bottle end of the partition wall 6 and, on the other hand, with 25. the cover 1 through a second part of the tube 3, defined by the partition wall 6, which forms the communication passage 6a. The bottle end of the partition wall 6 forms with the wall 4 a region C common to the two compartments A and B. An outlet orifice 7, which may be closed by a flap 8 is formed in the cover 1 in vertical alignment with the 30. . passage 6a.
A first orifice 9 is formed in the lateral wall of the compartment A. The orifice 9 is formed in the vicinity of the connection of the compartment 5. A to the cover 1. The orifice 9 puts this compartment A in communication with the rest of the bottle F. A second orifice 10 is provided at the end of a tube 11 extending through the inclined wall 4 at the connection of the latter to the tube 5 and 10. is located at the level of the connection of the inclined wall 4 to the tube 3. The second orifice 10 puts the bottle end of the compartment A in communication with the interior of the bottle F, Further, the partition wall 6 has an orifice 12 15. located at a level slightly nearer to the cover 1 than is the orifice 10.
The measuring device operates in the following manner: With the flap 8 open, the bottle F is inclined 20. from it's normal or storage position (in which its cap is uppermost) so as to reach the position illustrated in Figure la. The liquid contained in the bottle F then enters the measuring compartment A by way of the orifice 9 and rises in this measuring 25. compartment while expelling the air contained therein which escapes to the interior of the bottle by way of the tube 11. This rise in the level of the liquid continues until the liquid level reaches the orifice 10, though there may be a slight overrun 30. producing a slight excess of liquid constituting the 6. liquid termed free liquid.
The bottle is then returned to its normal position (Figure lb). The liquid of the compartment A flows under gravity down into the compartment B 5. along the partition wall 6 and the wall 4, the relative volumes of the compartments A and B being such that the level of the liquid in compartment B reaches a point slightly above the connection of the inclined wall 4 to the tube 3, i.e. above the 10. orifice 10. The slight excess of liquid above the orifice 10 is returned to the bottle by way of this orifice and the tube 11 which thus performs the function of an overflow for the compartment B. This return is facilitated by the orifice 12 provided in 15. the partition wall 6. This air inlet indeed ensures the equilibrium of the level in the compartment B and the base of the compartment A up to the level of the orifice 10.
The volume of the compartment B measured up to 20. the level of the orifice 10 corresponds to the volume of the required measure while the volume of the compartment A is slightly greater, as explained before.
In order to obtain a sufficient precision in 25. the volume of the measured amount of product, the intermediate chamber C interconnecting the compartments A and B has a minimum volume; further, its shape is such that it permits easy flow of the liquid into the compartment B.
At this stage, the bottle may be closed again 30. 7. by means of the flap 8. This measure of liquid located in reserve in the compartment B is ready for use. In order to dispense the liquid, the bottle F is tilted with the neck downwards (see Figure lc).
. The measured amount of liquid stored in the compartment B flows down the passage 6a to the exterior by way of the orifice 7. At the same time, the compartment A is again filled according to the procedure described above with reference to Figure 10. la.
Consequently, after the first utilization in the course of which the compartment B must be filled a first time, the measuring device can be used directly by inverting the bottle merely once.
. The measuring device, the principle and mode of operation of which have just been described, provides by its measuring in two stages in the compartments A and B a high precision in the dispensed measured amount of liquid. Further, it 20. lends itself remarkably well to simple and cheap manufacture, for example by moulding in plastics material.
Figures 2 to 5, and 7 to 9 illustrate such a practical embodiment, and Figure 6 a modification 25. thereof.
In order to permit easy moulding, the measuring device may be manufactured in two elements, the first being illustrated in Figures 2, 4 and 7 and the second in Figures 3, 5 and 8. Figure 9 30. shows the two assembled parts in perspective. 8.
The first element comprises the means for closing the bottle F, namely the cover 1 with its skirt 2 and its closing flap 8 pivotally mounted on the cover 1 and clipping onto a cap portion 13. The 5. flap 8 is provided with a stopper 21 adapted to be a force fit in the orifice 7 so as to close the latter.
The closing device constructed in this way may comprise, at the base of the skirt 2, a screwthread portion or a clipping portion 14 provided, if 10. required, with an orientation notch 15 which is engaged on a portion provided on the exterior of the neck of the bottle.
Advantageously, there is provided in the closing device an inner skirt 16 which is shorter 15. than the outer skirt 2 and ensures a seal on the upper part of the interior of the neck.
Apart from the closing device, the first element comprises the cylindrical tube 3 provided with its upper orifice 9 which is preferably 20. inclined downwardly and outwardly and the partition wall 6 and its orifice 12 which may be provided, as illustrated in Figure 2 and as more readily seen in Figure 7, in the form of a slot. Preferably, as shown, the partition wall 6 is curved so as to 25. enable the liquid to flow easily from the compartment A to the compartment B while this liquid is prevented from returning into the compartment A during use of the bottle.
The inner end of the tube 3 has a clipping 30. means 17 cooperative with a complementary means 17a 9. of the second element and a system 18 for preventing rotation which also cooperates with a complementary system 18a of the second element.
This second element affords the tube 5, the 5. inclined wall 4 and the tube 11 provided with its orifice 10, the whole being in one piece.
As can be seen in Figures 5 and 8, the tube 5, closed at its base, it semi-cylindrical and comprises a first cylindrical wall portion 19 10. adapted to be in extension of the cylindrical wall of the tube 3, and a second wall portion 20 which adjoins the tube 11 and is planar or preferably, as shown, outwardly convex and curved so as to increase the section of the passage from the compartment A to 15. the compartment B between this wall 20 and the partition wall 6.
In a modification shown in Figure 6, the second element may also include the first orifice 9 of the compartment A. In this case, the tube 3 is 20. not provided with this orifice in the vicinity of its connection to the cover 1. This orifice is replaced by a tube 9a which is in one piece with the wall 4 of the second element and forms a plunger tube in the compartment A when the two elements are 25. clipped together.
It will be clear from the foregoing that the present invention provides a measuring device of high precision, easy to place in position on a bottle of which it also constitutes the closing 30. device and moreover which is easy to manufacture, 10. owing to the fact that it is made in two elements which are easily mouldable and assembled.
