Description
DOSING CAP FOR GRANULATED SUBSTANCES
The present invention refers to a dosing cap for granulated substances.
As known, granulated substances, both for food use, such as for example sugar, coffee, salt, or aimed for other applications, are, in the majority of cases, proposed in vessels equipped with a spout, that is removable from the vessel, through which the substance is able to be poured.
It is however clear that, in such a way, the spout only allows continuously pouring the granulated substance, such characteristic being useful in case a great amount of the product has to be uncontrollably poured, while this could create some inconvenience when it is necessary to use limited and defined amounts of the substance: in this latter case, in fact, by using this type of vessels, in order to perform a more or less accurate product dosing, it is necessary to rely on the sensitivity of the person that pours, or to use a separate dosing tool, such as for example a graduated vessel.
In order to solve this already known problem, the art has proposed a series of dosing devices to be inserted in vessels of granulated or powdery substances, such as for example those
disclosed in EP-A-O 662 296 and US-A-I 877 808. Such dosing devices are generally equipped with a dosing cup, communicating with the vessel interior by means of a series of slits, and with the vessel exterior through a delivering cannula or channel centrally arranged above the dosing cup. Such dosing devices however correctly operate only when they are associated with vessels in which the delivering channel determines a delivering flow direction of the granulated substance substantially parallel to the main height axis of the vessel (such as for example in case of classical bottles) . Such dosing devices in fact, being generally equipped with slits obtained on the whole circumference of the dosing cup, are ill fitted for an operation in association with vessels in which the delivering channel determines a delivering flow direction of the granulated substance that is slanted with respect to the main height axis of the vessel itself (such as, for example, in case of known vessels that are equipped on their top side with at least one pair of slanted walls adapted to be joined to close the vessel, walls in which it would desirable to place at least one dosing device) . Under such situation, in fact, the use of a known dosing device, arranged however in a slanted position, would make the granulated substance go out of the slits placed in a lower position with respect to the slanted dosing cup, consequently preventing a correct substance dosing. Moreover, the substantially central
position of the delivering channel with respect to the dosing cup of known dosing devices would generate a substance seepage around the channel itself, creating a substance waste and again dosing inaccuracies.
Therefore, object of the present invention is solving the above prior art problems by providing a dosing cap for granulated or powdery substances that can be efficiently used in association with vessels in which the delivering channel of the dosing cap determines a delivering flow direction of the granulated substance that is slanted with respect to the main height axis of the vessel.
The above and other objects and advantages of the invention, as will appear from the following description, are obtained with a dosing cap for granulated substances as claimed in claim 1. Preferred embodiments and non-trivial variations of the present invention are the subject matter of the dependent claims .
The present invention will be better described by some preferred embodiments, provided as a non-limiting example, with reference to the enclosed drawings, in which:
FIG. 1 shows a sectional view of a preferred embodiment of the dosing cap according to the present invention associated with a slanted wall of a vessel of a granulated or powdery substance;
FIG. 2a shows a side view of the dosing cap of FIG. 1;
FIG. 2b shows a sectional view of the dosing cap according to the present invention along section line A-A of FIG. 2a;
FIG. 2c shows a perspective sectional view of the dosing cap of FIG. 2b;
FIG. 3a shows a sectional view of another preferred embodiment of the dosing cap according to the present invention; and
FIG. 3b shows a perspective sectional view of the dosing cap of FIG. 3a. *
With reference in particular to FIG. 1, it is possible to note that the dosing cap 1 according to the present invention is aimed to be inserted in a suitably sized opening obtained on a portion of a wall 30 of a vessel 31 containing a granulated or powdery substance, both for food use, such as for example sugar, coffee, salt, minced spices, or obviously aimed for other applications, such dosing cap 1 being adapted to allow a delivery of such substance, in certain and measured doses, through at least one delivering channel 3 communicating at least one dosing and delivering vessel 5 of the cap 1 itself with the vessel 31 exterior, such delivering channel 3 determining a direction (designated in FIG. 1 with arrow F) of the delivering flow of the granulated substance that is slanted with respect to a main height axis (designated in FIG. 1 by arrow Y) of the vessel 31. Consequently, as will be described below in greater detail, the dosing cap 1 according
to the present invention is realised in order to be advantageously inserted in a wall 31 of the vessel 30 that is substantially orthogonal to direction F and therefore also slanted with respect to axis Y-Y (such as, for example, in the above known vessels) .
With reference in particular to Figures 2a to 2c, it is possible to note that, in order to be placed on the slanted wall 30 of the vessel 31, the dosing cap 1 according to the present invention comprises at least the dosing and delivering vessel 5 communicating with the vessel 31 interior for a granulated or powdery substance only through at least one upper slit 7 and at least the delivering channel 3 that communicates at least the dosing and delivering vessel 5 with the vessel exterior.
In the preferred embodiment of the dosing cap 1 according to the present invention shown in Figures 1 to 2c, the delivering channel 3 is integrated inside a delivering cap 9 arranged outside the vessel 30 and in which, obviously, the delivering channel 3 enters through at least one delivering opening 3a. Inside the delivering cap 9, the delivering channel 3 can define at least one dosing chamber 9a adapted to help the dosing and delivering vessel 5 in its dosing function of the substance contained inside the vessel 31.
In order to allow the dosing cap 1 seal to the wall 30 of the vessel 31, it is externally _equipped with at least one
connecting flange 11, that is preferably continuous, circular and perimetral to the dosing and delivering vessel 5, whose surface can be connected, for example through gluing, internally or externally to the perimetral surface of the wall 30 opening inside which the dosing cap 1 is inserted. Preferably, the connecting flange 11 is connected to the perimetral surface of the wall 30 opening inside which the dosing cap 1 is inserted through ultrasound welding. Obviously, other arrangements can be used, such as for example a mechanical engagement.
If it is desirable to have more than one upper slit 7 available, they obviously could be suitably arranged over the dosing and delivering vessel 5 and spaced by an adequate number of ribs 7a.
In order to avoid that a substantially central position of the delivering channel 3 with respect to the dosing and delivering vessel 5, as well as in known dosing devices, causes a substance seepage around the channel in internal portions of the delivering cap 9 different from the dosing chamber 9a, consequently generating a waste of the substance and dosing imperfections, the delivering channel 3 can be arranged so that the delivering direction F is offset with respect to a central symmetry axis C-C of the dosing and delivering vessel 5.
In order to increase the impossibility of substance
seepage around the delivering channel 3 in internal portions of the delivering cap 9 different from the dosing chamber 9a and to make it easier to deliver the substance from the dosing and delivering vessel 5, an end of the delivering channel 3 can be equipped with a lead-in countersink 3b next to the dosing and delivering vessel 5.
From what is described above, the use of the dosing cap 1 according to the present invention is therefore extremely simple and practical: by inclining the vessel 31, it is possible to fill the dosing chamber 9e, and possibly the dosing and delivering vessel 5, with the granulated substance through the upper slits 7, as pointed out by arrow S in Figures 1 and 2b (obviously, the slanting amount will depend on the residual amount of granulated substance inside the vessel) and, taking back the vessel in a substantially vertical position (axis Y-Y is therefore substantially vertical) , the determined substance to be delivered will remain inside the dosing vessel 5. Advantageously, since the dosing cap 1 of the present invention is equipped only with upper slits 7 and not with lower slits (namely, arranged along the whole circumference of the dosing and delivering vessel 5, as instead occurs in the dosing caps according to the prior art) , when the vessel is taken back in a substantially vertical position, the granulated substance contained inside the dosing and delivering vessel 5 has no ways out,
consequently allowing an accurate and constant dosing.
Now, by again inclining the Vessel, the dose of substance contained inside the dosing and delivering vessel 5 will go outside, possibly through the lead-in countersink 3 and, possibly, the delivering opening 3a.
Depending on the nature of the granulated substance contained inside the vessel 31 to be dosed and delivered, it will obviously be possible to define the measure of the determined and measured dose that the dosing cap 1 is able to deliver, by suitably sizing the volume of the dosing and delivering vessel 5, and possibly of the dosing chamber 9a.
Obviously, the dosing cap ύ. according to the present invention can be equipped with a further cap (not shown) , possibly integrating at least one warranty seal, aimed to close the delivering channel 3, and in particular possibly the delivering opening 3a, in order to protect the substance inside the vessel 31 from dust, dirt or other elements that could impair its hygiene and/or its correct storage. In particular, the closing cap can be realised as a cap of the vvflip-top" type, or an adhesive system or also a system of the "push-pull" type.
Advantageously, the whole dosing cap 1 according to the present invention, and consequently each one of the parts composing it as previously described, could all be made of the same material, such as for example a plastic material.
In a preferred embodiment thereof, with reference to Figures 3a and 3b, the dosing cap 1 can be manufactured by joining at least two separately produced parts, respectively an upper part Ia and a lower part Ib, the upper part Ia comprising the delivering cap 9 and the related delivering channel 3, and the lower part Ib comprising the dosing and delivering vessel 5 and the rela.ted upper slits 7. The upper part Ia and the lower part Ib are mutually joined to form the dosing cap 1 respectively through an upper flange 11a and a lower flange lib with which they are equipped. The connection of the upper flange 11a and the lower flange lib, for example by gluing, ultrasound welding or engagement, globally brings about the formation of the connecting flange 11.
