Description
DOSING CAP FOR DISPENSING LIQUIDS FROM DEFORMABLE CONTAINERS
The invention is a dosing cap particularly suitable for being applied to deformable containers containing liquids. It is well known that certain liquid products are put on the market into deformable containers provided with graduated dosing cap. Particularly, said dosing cap consists of a collar applied to the neck of the container and of a bowl provided with marks indicating the volume of the dose which, by squeezing the container, is introduced in the bowl through a dispensing pipe substantially positioned at the centre of the bowl itself. Said dispensing pipe, in fact, is provided with a small tube which draws the liquid from the container on one side and with one or more openings allowing the passage of the liquid from the container to the bowl on the other side. A cover ensures the sealing action both in correspondence with the edge of the bowl dispensing mouth and in correspondence with the dispensing pipe, on which the dispensing openings are made. In the dosing caps of the known kind, one of the drawbacks is represented by the fact that if the deformable container is squeezed too energetically, the liquid is conveyed to the dispensing pipe at excessive speed and flows out of the dispensing mouths not sufficiently inclined with respect to the vertical axis, thus risking of being spilt out of the bowl. In fact, in the manufacture of the cap the dispensing mouths are carried out by making one or more lateral openings in correspondence with the upper closed end of the tubular element which forms the dispensing pipe. Said lateral openings extend also to part of the upper surface which closes the dispensing pipe itself. The removal of part of said upper surface, therefore, eliminates the barrier which holds the upward flow of the liquid in case of too energetic squeezing of the container.
In order to eliminate said drawback, dosing caps have been implemented which, in correspondence with the upper part of the dispensing pipe, are provided with a diffuser with concave
profile facing towards the bottom of the bowl, and said diffuser deviates the liquid which is flowing out of the dispenser openings and conveys it towards the bottom of the bowl itself. This solution makes it possible to avoid the risk of having the liquid sprayed out of the bowl in case of excessively energetic deformation of the container. However, this results in a further inconvenience, that is, when the cover closes the bowl, in case of deformation of the container there is no seal against the accidental outflow of liquid from the dispensing pipe into the inside of the bowl. In fact, since the external diameter of the diffuser exceeds the external diameter of the dispensing pipe, when the cover is closed it doesn't intercept the dispensing openings made on the dispensing pipe. In order to eliminate also this drawback, the cap object of the present invention has been designed and implemented.
One of the aims of the invention is, in particular, the implementation of a dosing cap provided with a bowl for collecting the dispensed liquid, which should prevent the spilling of the liquid outside the bowl in case of excessively energetic deformation of the container.
Another aim of the invention is that when the cover is closed the dosing cap object of the invention should have a sealing effect both in correspondence with the bowl edge and in correspondence with the dispensing mouth of the dispensing pipe.
The above goals are achieved through the implementation of a dosing cap for dispensing liquids from deformable and flexible containers, which, according to the main claim, comprises:
- a bowl containing a chamber for the collection of the dispensed liquid, provided with means suitable for connecting it to the neck of a deformable and flexible container;
- a dispensing pipe with tubular section, positioned in the chamber of said bowl and provided with a small tube which draws the liquid contained in said container on one side and, on the opposite side, with a diffuser having an internal concave
profile facing towards the bottom of said bowl and suitable for conveying the liquid flowing from the dispensing mouth of said dispenser into the bowl itself when said container is squeezed; - a cover provided with a peripheral collar bucking with sealing effect against the annular edge of the dispensing mouth of said bowl and with an appendix which bucks against the external surface of said diffuser, and is characterized in that, in correspondence with said concave profile, said diffuser is provided with coupling means which slidingly cooperate with said dispensing pipe when said cover is open and with first sealing means which buck against said second sealing means belonging to said dispensing mouth of said dispenser when said cover is closed. According to a favourite application of the invention in question, the coupling means with which said diffuser is provided interfere with a holding annular area obtained near the dispensing mouth of the dispensing pipe. This way, the diffuser remains open in the dispensing position. The bowl of said dosing cap is provided with marks, on each one of which the volume of the dispensed dose is indicated.
According to another practical application, said dispensing pipe is provided with more than one holding annular areas, each one of which defines a different stop position of the diffuser in the opening phase, each position corresponding to a different dose to be dispensed.
To advantage, the dosing cap object of the present invention prevents the spilling of the liquid out of the bowl which is part of the dosing cap, even in case of violent squeezing of the container. Equally to advantage, said dosing cap provides also a double sealing effect, both in correspondence with the dispensing mouth of the bowl and in correspondence with the dispensing mouth of the dispensing pipe, thus gathering in itself all the characteristics and the advantages offered by the known kinds of dosing cap provided with graduated bowl.
The above-described aims and advantages will be better highlighted in the description of a practical application among many of the invention in question, illustrated in the attached tables: - figure 1 shows the dosing cap object of the invention with closed cover, applied to a deformable and flexible container;
- figure 2 shows the dosing cap and the container to which it is applied with open cover and during the dispensing of the liquid into the bowl; - figure 3 shows the dosing cap and the container to which it is applied during the suction inside the container itself of part of the liquid dispensed into the bowl;

- figures 9, 10, 11, 12 and 13 show different dispensing positions of the variant of the cap represented in figure 8;

- figure 15 shows a further variant of the holding means made in the dispensing pipe and of the coupling means belonging to the diffuser.
As shown in figure 1, the dosing cap object of the invention, referred to as a whole by 1, comprises a bowl 2 applied to the neck 31 of a deformable and flexible container 3 through connecting means 21. Said bowl 2 is internally provided with a
chamber 22 which is closed by means of a cover 4 and inside which there is a dispensing pipe 5 having tubular section. The dispensing pipe is connected with a small tube 6 which draws the liquid 32 contained in said container 3 on one side and, on the opposite side, with a diffuser, referred to as a whole by 7, the inside of which, as shown in detail in figures 5 and 7, has concave profile 71 facing towards the bottom of the bowl 2. The concave profile 71 conveys into the bowl 2 the liquid which, as described in detail below, when the container 3 is deformed, for examble through squeezing, flows into the chamber 22 through the dispensing pipe 5.
When the cover 4 of the cap, as shown in figure 1, is closed, the peripheral collar 41 of the cover itself interferes with the annular edge 23 of the dispensing mouth 24 of the bowl 2, while the appendix 42, positioned at the centre of the cover 4 itself, bucks against the external surface 72 of the diffuser 7, which has a sealing action in correspondence with the dispensing mouth 51of the dispenser 5. In fact, as shown in figures 5, 6 and 7, said diffuser 7 is provided with an appendix 174 having in intermediate position first sealing means, consisting of an annular edge 73 with truncated cone-shaped profile, which buck against second sealing means belonging to said dispensing mouth 51 of said dispensing pipe 5 and consisting of an annular edge with convex profile 53. Obviously, when the cover 4 is closed on the bowl 2, it has a sealing action both outwards in correspondence with the dispensing mouth 24 of the bowl 2 and towards the inside of the chamber 22 in correspondence with the dispensing mouth 51 of the dispenser 5, thus preventing any outflow of liquid in case of accidental or intentional pressure exerted on the container 3.
It can also be observed that said diffuser 7 is sliding ly coupled inside said dispensing pipe 5 through coupling means consisting of at least one couple of corner-shaped protrusions 74, each one of which is made at the end of said appendix 174 projecting out of the inner part of the diffuser 7. Said corner-shaped
protrusions 74 slidingly couple inside the dispensing pipe 5, as shown in figure 1, while they interfere with the holding means belonging to the dispensing pipe 5 itself and consisting of at least an extreme annular indented area 54, made in correspondence with the dispensing mouth 51 of the dispensing pipe 5 itself. The diffuser 7 is therefore axially sliding along the dispensing pipe 5 and takes a stable position, as shown in figures 2, 3, 4 and 7, when its corner-shaped protrusions 74 couple in the extreme annular area 54 of the dispensing pipe 5. This position corresponds to the phase in which the product is dispensed into the chamber 22 of the bowl 2, as described here below.
The bowl 2 is provided with marks 125, in correspondence of each of which a number representing the volume of the dose corresponding to that mark is indicated.
To dispense the desired dose, it is sufficient to open the cover 4 in such a way as to position the container as shown in figure 2, while by acting on the sides of the container 3 through a lateral pressure 33 one obtains the flow of the liquid 32 up the small tube 6 according to the direction 35, until it reaches the concave surface 71 of the diffuser 7. The pressure of the liquid lifts the diffuser 7, opens the dispensing mouth 51 of the dispensing pipe 5 and the liquid flows into the chamber 22 of the bowl 2. During this phase the diffuser 7 remains open, since its corner-shaped protrusions 74 buck against the extreme annular area 54, so that the user, by dosing the pressure 33, can make the liquid reach the desired mark. It can be observed that the curvature of the concave surface 71 of the diffuser 7 always conveys the flow of the liquid 32 towards the bottom of the bowl 2 and prevents this from being spilt outside the bowl 2 itself, even if the user inadvertently exerts an excessive squeezing pressure 33.
If the user wants to dose the maximum quantity of liquid corresponding to the highest mark 125, he just needs to squeeze the container 3 until filling the chamber 22 over the
mark 125, and therefore without having to dose the pressure checking if the level 125 has been reached. In fact, as shown in figure 3, when the pressure 33 is released the elastic return of the container 3 causes the suction of the liquid 225 which flows into the container 3 until reaching the mark 125 following the direction 135.
After the use of the dispensed liquid, the cover 4 closes, its appendix 42 interferes with the external surface 72 of the diffuser 7 and the already described sealing conditions obtained when the cover 4 is closed as shown in figure 1 are thus restored.
A practical variant of the cap object of the invention, referred to as a whole by 10, is shown in figure 8, where it is possible to observe that the dispensing pipe 50 is provided with a plurality of holding means which, beside a first extreme annular area 540 include a first annular area 541 and a second annular area 542, obtained in intermediate positions in the body of said dispensing pipe 50. This involves that the diffuser 70'can be locked in different positions, each allowing the dispensing of a prefixed volume of liquid. Therefore, if, for example, starting from the position shown in figure 8 and after opening the cover 40 the container is squeezed, the pressure of the liquid moves the diffuser 70 from the position shown in figure 8 to the position shown in figure 9, where its corner-shaped protrusion 741 is stopped by said second annular area 542, which makes it possible to dose the maximum quantity corresponding to the third mark 252. Even in this case, on release of the pressure any quantity of liquid exceeding the mark 252 is sucked in. To dispense a volume of liquid corresponding to the second mark 251, as shown in figure 10, it is sufficient to pull upwards (vertical direction 171) the jut 170 and to lift the diffuser 70 until its corner-shaped protrusion exceeds said second annular area 542. Upon the squeezing of the container, as shown in figure 11, the pressure of the liquid lifts the diffuser 70 until stopping it when its corner-shaped protrusions 741 meet said
first annular area 541. The volume of the liquid dispensed inside the chamber 220 of the bowl 221 thus corresponds to the second mark 251.
Similarly, if the user wants to dispense a volume of liquid corresponding to the first mark 250, as shown in figure 12, he has to pull the dispenser 70 further, until this is positioned so that its corner-shaped protrusion 741 exceeds the first annular area 541. If pressure is exerted on the container, the diffuser 70, as shown in figure 13, further lifts up and stops when its corner-shaped protrusions 741 couple with said extreme annular area 540, thus making it possible to dispense the volume of liquid corresponding to the first mark 250.
The above description shows that the cap object of the invention and all its described variants achieve the fixed goals. As first thing the invention makes it possible to always pour the liquid inside the bowl, avoiding any outflow of the liquid itself if excessive pressure is exerted on the container. Further, when the cover is closed, both the seal of the bowl outwards and the seal of the dispensing mouth of the dispensing pipe towards the chamber of the bowl are ensured also in case of accidental or intentional squeezing of the container.
Figure 4 shows a further variant of the invention in question, in which the diffuser 700 is provided with corner-shaped protrusions 841 positioned outside the dispensing pipe 500.
Similarly, in this case the holding means consist of an extreme annular area 740 positioned at the end of and outside said dispensing pipe 500. Another variant is shown in figure 15, where on the dispensing pipe 510 there are further holding means consisting of the extreme annular area 840 and also of intermediate annular areas 841 and 842 suitable for defining different dosing volumes in correspondence with different marks by interfering with said corner-shaped protrusions 941 of said diffuser 710. Obviously, upon implementation changes can be made in the
shape and dimensions of the dosing cap object of the invention and if necessary the internal and external profiles of the diffuser can be changed, too.
Further, the bowl and its chamber for the collection of the dispensed liquid can take any shape and dimension and can be provided with marks indicating any volume.
Any variant is to be considered as completely protected by the invention in question.
