Description

DOSING CAP WITH HERMETIC SEAL, PREFERABLY FOR LIQUIDS
DESCRIPTION
The present invention relates to a dosing cap with hermetic seal containing, preferably, a liquid to be mixed, exclusively at the moment of its use, with a liquid contained in the container (normally a bottle or a flask) to which the cap is applied.
Dosing caps are widely used, in particular in the pharmaceutical sector, for keeping a (more) easily degradable component, contained in the cap, separate from a second (more) stable component, contained in the container, until the moment of use.
With explicit reference to the pharmaceutical field, if an active principle (for example an antibiotic or a vitamin complex) is (more) easily degradable when it is dissolved in the component contained in the flask, it is a common practice to package said active principle in the cap in a (more) stable form (for example, in the form of a liquid or of a powder) and to mix it, at the moment of use, with the component contained in the flask, tearing a membrane that seals the cap.
In said known dosing caps, the component contained in the cap is set inside a body having a substantially cylindrical shape, which is mobile within the body of the cap inserted in the neck of the container; by exerting a pressure on the (substantially) cylindrical body, its bottom edge tears the sealing membrane causing the contents of the cap to drop into the liquid present in the container.
In said known dosing caps, the bottom edge of the (substantially) cylindrical body has an inclined profile, like the mouthpiece of a flute, which presents the drawback of breaking off at least part of the sealing membrane of the cap, causing the broken part to drop into the liquid contained in the container.
Dosing caps are also known of the type comprising an outer body (suitable for insertion in the neck of the container to which the cap is applied) and an inner body (containing the powder or the liquid and mobile within the outer body) in which the inner body houses a body, adjacent to the inner surface of the inner body, suitable for tearing the sealing membrane of the dosing cap in response to an axial pressure exerted on the upper part of the inner body. The use of said dosing caps is fully satisfactory if the inner body contains a powder to be dissolved in the liquid contained in the container; some problems have been encountered, on the other hand, when the inner body contains a liquid to be mixed with that contained in the container.
As a non-limiting example, we refer to the case in which the container contains a nonalcoholic drink (such as Coca Cola(R), Sprite(R) or other fizzy drink, etc.) to be mixed with a set amount of an alcoholic liquid (such as rum, whisky, etc.) contained in the dosing cap in order to prepare a drink on the spot.
Since mixing of the two liquids requires the container to be shaken vigorously, using the dosing cap previously described a (possible) leakage of liquid from the above-mentioned dosing cap has been encountered during opening of said cap and/or while shaking the container to mix the two liquids.
Object of the present invention is to provide a hermetic dosing cap without the above- mentioned drawbacks and is achieved by producing a dosing cap that has the characteristics of the attached independent claim 1 ; further characteristics of the invention appear from the dependent claims.
A dosing cap produced according to the invention can be advantageously used also if the product to be mixed with the liquid contained in the container is a powder.
The invention will now be described with reference to its embodiments, purely as examples and therefore non-limiting, illustrated in the attached drawings, in which:
- figure 1 shows schematically a side view, sectioned according to the plane B-B of figure 2, of a dosing cap produced according to the invention;

- figure 7 shows, enlarged, the detail highlighted in figure 6; - figures 8-10 show the dosing cap of figure 1, in which the sealing element is incorporated in a sealing cover of the container;
- figures 11-13 show the dosing cap of figure 1 surmounted by a sealing cover of the container of the water-bottle type, modified; - figure 14 shows, in section, a dosing cap like that of figure 8, in which the body suitable for tearing the sealing membrane has an axial through hole;
- figures 15 and 16 show, enlarged, two details of the dosing cap of figure 14;
- figure 17 shows the dosing cap of figure 14 with the sealing membrane torn;
- figures 18 and 19 show, in section, a dosing cap in which the body of the dosing cap is integral with the sealing cover of the container.
In the attached figures the corresponding elements will be identified by the same reference numbers.
Figure 1 illustrates schematically a side view, sectioned according to the plane B-B of figure 2, of a dosing cap produced according to the present invention, indicated overall by 1.
The cap 1 comprises a body 2, suitable for insertion in the neck of the container 100 (figure 5) to which the cap 1 is applied and containing the product (omitted in the attached figures to simplify the graphic representation) to be mixed with that contained in the container 100.
The product contained in the cap 1 is preferably a liquid but, without departing from the scope of the invention, it can be a product in powder form.
The body 2 is closed at the top by a sealing element 3, flexible and fixed along the upper edge of the body 2 and at the bottom by a sealing membrane 5 provided with a preset tear line 6 (figure 3); in the centre of the body 2 a body 4 is located, suitable for tearing - in response to an axial pressure exerted on the central area 7 of the sealing element 3 - the sealing membrane 5 along its preset tear line 6 to allow the product (liquid or powder) contained in the cap 1 to drop into the liquid contained in the container 100.
Advantageously, the body 4 is integral with the sealing membrane 5.
Without departing from the scope of the invention, the membrane 5 can be replaced by a sealing body known per se, integral with the body 4 and fixed in a known way (for example slotted in or welded) to the lower edge of the body 2.
The sealing element 3 consists of a body made of a flexible material, which comprises the central area 7 of substantially cylindrical shape and protruding at the top from the element 3, an annular intermediate area 9 folded concertina- fashion and an outer area 10 suitable for press-insertion along the upper edge of the body 2 and welded there (in a per known manner, for example by ultrasound) to provide the cap 1 with a hermetic seal.
In the lower part of the body 2 there is also a reinforcement element 8, inclined, positioned between the side wall of the body 2 and the area of its bottom wall adjacent to the preset tear line 6, which facilitates the breaking of the sealing membrane 5 along the preset tear line 6.
In the preferred embodiment described here, the body 4 is a cylindrical body having a "star" section but, without departing from the scope of the invention, the body 4 can have the form and the section considered most advantageous each time to meet specific needs.
Above the dosing cap 1 the cover of the container 100 (omitted in figures 1-7 because it is known per se and in any case extraneous to the present invention) is applied in a per se known manner.
Figure 2 shows a top view of the dosing cap 1 and illustrates the sealing element 3 (comprising the central area 7 of substantially cylindrical shape, the annular intermediate area 9 folded concertina- fashion and the outer area 10 suitable for being welded along the upper edge of the body 2) and an outer annular flange 11 having a plurality of through slots 12 (not described because known per se) which allow the user to drink the mixture of liquids contained in the container 100 without having to remove the dosing cap 1.
The outer annular flange 11 having a plurality of slots 12 can be omitted without departing from the scope of the invention.
Figure 3 shows a top view of the dosing cap 1 without the sealing element 3; figure 3 shows the sealing membrane 5 with the preset tear line 6, the reinforcement element 8, the outer annular flange 1 1 having a plurality of through slots 12 and the body 4. The preset tear line 6 has an interruption in the area nearest the wall of the body 2 so that, when the membrane 5 is torn, a peduncle 13 is created which retains the torn membrane 5 preventing it from falling into the container 100 and thus making the cap 1 childproof.
Figure 4 shows a perspective view, partially sectioned, of the dosing cap 1 ; in figure 4 the body 2 closed at the top by the sealing element 3, the body 4, the outer annular flange 1 1 having a plurality of slots 12, the sealing membrane 5 with the preset tear line 6 and the reinforcement element 8 can be seen.
Figure 5 illustrates schematically a sectioned side view of a container 100 in the neck of which the body 2 of the dosing cap 1 is inserted while the sealing element 3 is separated from the body 2 of the cap 1 ; figure 5 also shows the body 4 located inside the body 2, the sealing membrane 5 and the reinforcement element 8.
As can be seen from figure 5, in the embodiment described here the outer wall of the body 2 is not in contact with the inner wall of the neck of the container 100 to allow the liquid present in the container 100 to reach the slots 12, if present.
Figure 6 shows the dosing cap 1 with the sealing membrane 5 torn by the body 4; from figure 6 it can be seen that, as a result of an axial pressure (indicated in the figure by an arrow) exerted on the central area 7, the central area 7 has entered the dosing cap 1, causing the concertina-type intermediate area 9 of the element 3 to lie flat and inducing the body 4 to tear the membrane 5 along the preset tear line 6.
From figure 6 it can also be seen that, advantageously, the body 4 (having one end integral with the sealing membrane 5 and the other end inserted in the central area 7 of the sealing element 3) is sufficiently flexible to permit the membrane 5 to rotate around the peduncle 13 when it is torn by the body 4, without any risk of breaking the peduncle.
Figure 7 shows, enlarged, the detail highlighted in figure 6, which shows the outer area 10 of the sealing element 3 press-inserted on the upper edge of the body 2 before being welded to it: the upper edge of the body 2 has a protruding area 14 which is press- inserted in a slot of complementary shape made in the outer area 10 of the sealing element 3. Figures 8-10 show the dosing cap 1, as described by figures 1-7, the sealing element 3 of which has been incorporated in the cover 21 of the container 100 to form a single body; in the central portion of the cover 21 there are the substantially cylindrical central area 7 and the annular intermediate area 9 folded concertina-fashion of the element 3; the outer area 10 of the element 3 is incorporated in the area of the cover 21 adjacent to the intermediate area 9.
The sealing membrane 5 is torn in a substantially analogous way to that previously described with reference to figure 5.
In the embodiment illustrated in figures 8-10 the dosing cap 1 comprises the outer annular flange 1 1 without the slots 12.
Figure 8 shows schematically a sectioned side view of a dosing cap 1 incorporated in the cover 21 ; figure 9 shows schematically a sectioned side view of the dosing cap of figure 8 put into the neck of a container 100; figure 10 shows schematically the dosing cap of figure 8 in which the cover 21 is separated from the container 100 and from the body 2 of the dosing cap 1.
Advantageously, on the inner surface of the cover 21 there are a plurality of ledges 121 suitable for engaging with the annular flange 11 of the dosing cap 1.
The figures 11-13 show the dosing cap 1 surmounted by a sealing cover 31 of the container 100, of the water-bottle type, which comprises a spout 32, an annular intermediate area 33 folded concertina-fashion and an outer area 34 suitable for being fixed in a per se known manner to the neck of the container 100.
Figure 11 shows schematically a sectioned side view of a dosing cap 1 surmounted by a sealing cover 31 of the water-bottle type (seen better in figure 13), which comprises a spout 32, an annular intermediate area 33 folded concertina-fashion and an outer area 34 suitable for being fixed in a per se known manner to the neck of the container 100.
Figure 12 shows schematically a sectioned side view of the cover 31 and of the dosing cap 1 in which an axial pressure (indicated in the figure by an arrow) exerted on the spout 32 of the cover 31 has caused the laceration of the sealing membrane 5 along the preset tear line 6; figure 13 shows schematically the container of figure 12 in which the cover 31 and the sealing element 3 are shown separated from the container 1 OO and from the body 2 of the dosing cap 1 , respectively.
As shown in figure 12, as a result of an axial pressure exerted on the spout 32 of the cover 31 , the spout 32 enters the cover 31 causing the concertina-type intermediate area 33 of the cover 31 to lie flat and transferring the axial pressure to the central area 7 of the sealing element 3, which enters the dosing cap 1 causing the concertina-type intermediate area 9 of the sealing element 3 to lie flat and inducing the body 4 to tear the sealing membrane 5 along the preset tear line 6.
Advantageously, on the inner surface of the outer area 34 of the cover 31 there are a plurality of ledges 131 suitable for engaging with the annular flange 11 of the dosing cap 1.
Figure 14 shows, in section, a dosing cap 1 that differs from that illustrated in figure 8 due to the fact that the body 4 suitable for tearing the sealing membrane 5 has a through axial hole 170, that the area 7 of the sealing element 3 has a hole 171 at the level of the end of the axial through hole 170 adjacent to the area 7 and that the sealing membrane 5 has a hole 172 at the level of the end of the axial through hole 170 adjacent to the membrane 5.
The holes 170, 171 and 172 allow for the insertion in the container 100 of a straw or of the stem of a dispenser device (omitted in the attached figures because known per se) suitable for dispensing the contents of the container 100.
The dispenser device can be a sprayer or other functionally equivalent per se known device.
The hole 171 present in the area 7 of the sealing element 3 can be closed by the cover 21 or by a membrane seal (omitted in figure 14 to simplify the graphic representation) to be removed before inserting in the through hole 170 a straw or the stem of a dispenser device.
The figures 15 and 16 show, enlarged, two details of the dosing cap of figure 14.
Figure 15 shows the ledges 121 present on the inner surface of the cover 21 and suitable for engaging with the annular flange 11 of the dosing cap 1.
Figure 16 shows that the upper end of the body 4 is connected to the area 7 of the sealing element 3 by means of a plurality of ledges 173 which engage in corresponding seats made inside the area 7 of the sealing element 3, not visible in figure 16 since they are occupied by the ledges 173.
Without departing from the scope of the invention, the ledges 173 can be replaced by an annular ribbing, which engages in a corresponding groove provided inside the area 7 of the sealing element 3.
Figure 17 shows the dosing cap of figure 14 with the sealing membrane 5 torn and differs from figure 6 due only to the fact that the body 4, the area 7 of the sealing element 3 and the membrane 5 have a hole (170, 171 and 172, respectively).
Figures 18 and 19 show, in section, a dosing cap 1 that differs from that illustrated in figures 14-17 due to the fact that the body 2 of the dosing cap 1 is integral with the sealing cover 21 of the container 100.
Figure 18 shows the body 2 integral with the cover 21, the sealing element 3 (partially superimposed on the cover 21), the outer area 10 of which is fixed in a per se known manner to the cover 21 and the cylindrical area 7 of which presents the hole 171, the body 4 with the through hole 170 and the sealing membrane 5 with the hole 172.
Figure 19 shows the dosing cap of figure 18 with the sealing membrane 5 torn and differs from figure 17 due only to the fact that the body 2 is integral with the cover 21.
Without departing from the scope of the invention, the body 4 can be solid as shown in the figures from 1 to 13 and the holes 170, 171, 172 can therefore be omitted.
According to a further embodiment, not illustrated in the attached figures to simplify the graphic representation, the sealing element 3 of the dosing cap 1 described in the figures 1 -7 can be incorporated in the water-bottle type sealing cover 31 described in the figures 1 1-13, so as to form a single body.
As a result of an axial pressure exerted on the spout 32 of the cover 31, the spout 32 enters the cover 31 causing the concertina-type intermediate area 33 of the cover 31 to lie flat and transferring the axial pressure to the body 4, which tears the sealing membrane 5 along the preset tear line 6.
Without departing from the scope of the invention, a person skilled in the art can make to the cap to which the present invention refers all the modifications and the improvements suggested by his experience and by natural technical developments.
