Description

DESCRIPTION "Dispensing device"

[001] . The present invention relates to a dispensing device, as well as a dispensing bottle suitable for dispensing fluid in doses from a container.

[002] . The containers used for containing fluid substances have various shapes and denominations, some of which, commonly used, are for example: bottle, phial, cruet, can, tank, small bottle, vial, flask. [003] . For convenience, for the purposes of this description, the term "bottle" shall be used herein to denote any container suitable for containing fluid substances. [004] . The present invention relates to each of these or to any other shapes and denominations, provided they are referred to a container suitable for containing fluid substances provided with a dispensing device comprising at least one upper loading chamber and at least one lower collecting chamber. [005] . Devices of this type are described, for example, in US 5,480,071, US 5,129,561, GB 2,145,061, US 5,029,736, US 5,495,964, US 4,061,253, FR 2,804,755, US 4,614,285, EP 0,586,430, IT 1,236,746, US 5,148,953, US 4,449,651, FR 2,590,555 and US 4,015,758. [006], Most fluid products, for example those intended for home and fabric care and cleaning, are often sold on the market into containers provided with a device suitable for favouring a correct and regular dispensing of the amount of product to be used. [007] . As a non-limiting example, many bottles containing detergents or other fluid products for washing machines are provided with a dispensing cap which, once removed from the bottle, acting as a measure, allows the user to take a predetermined amount of product. [008] . In order to further facilitate the use, such amount is generally proportionate to the most common use the product is subject to: for example, with liquid detergents for washing machines, the cap may contain the amount needed for washing a basket of underwear; in the case of a detergent for floors, the cap may contain the suitable amount for preparing one bucket of solution, and so on.

[009] . In other cases, according to the prior art, the dispensing device consists of clear graduated insert obtained in the wall of the bottle, which allows the amount of remaining fluid to be checked after taking.

[0010] . Also in this case, the graduation is proportionate to the amount which is typically necessary to use (in many cases, for example, the bottle has a capacity of 1 litre and exhibits 10 notches corresponding to 1 decilitre each) .

[0011] . On the other hand, in the two cases described, as in many others, the use of the dispensing device requires certain ability by the user, and the accuracy of the taking mainly depends on the attention he/she has in dispensing the correct amount.

[0012] . In the case of the dispensing cap, for example, it may happen that the inexperienced user dispenses an excessive amount of product, spilling it over, thus wasting a part of the product and producing undesired mess; whereas in the case of the bottle provided with clear graduated insert, to avoid dispensing excess product as compared to the correct amount (corresponding to one notch on the graduated scale) , it is necessary to make the taking in stages, being very careful and in any case, running the risk of taking more than needed. [0013] . It is clear that these disadvantages are potentially stronger if the user is an old or disabled person or someone suffering from motor deficiencies. [0014] . The object of the present invention is to obviate the disadvantages mentioned above, and in particular to produce a container for fluid substances which should allow taking a predetermined amount of product in a simple and reliable manner. [0015] . Another object of the present invention is to produce a dispensing bottle which could be used with one hand only.

[0016] . A further object of the present invention is to produce a bottle provided with a dispensing device, of simple construction and at relatively low cost.

[0017] . These and other objects according to the present invention are achieved by producing a dispensing bottle according to claim 1. Further features are provided in the following claims. [0018] .

[0070] . Said outlet opening 25 extends with a collar 13 towards cap 28 for fluid-seal connecting to the output inlet 100 of said output duct 17, so as to prevent the fluid coming out of said outlet opening 25 from going into the measuring chamber 24.

[0071] . In accordance with a fourth general embodiment of the invention, a dispensing device suitable for a dispensing bottle which exhibits a container for containing a fluid to be dispensed through an opening, comprises at least two components 28, and 30 disconnectable from one another.

[0072] . One of said at least two disconnectable components comprises a cap 28 suitable for the fluid-seal connection to said opening 27 of container 10, and a second of said at least two disconnectable components comprises a tank 30 suitable for containing a dose of fluid to be dispensed.

[0077] . Said tank-cap connecting means comprise an inlet opening 29 and an outlet opening 25.

[0078] . Said inlet opening 29 is suitable for allowing the flow of fluid from said measuring chamber 24 of cap 28 to said tank. [0079] . Said inlet opening 29 extends with a collar 102 which protrudes towards cap 28 into the measuring chamber 24.

[0080] . Said outlet opening 25 connects to the output inlet 100 of said output duct 17, for the fluid connection of said tank with said output duct.

[0081] . In accordance with an even further general embodiment, a dispensing bottle 20 comprises at least one container 10, provided with at least one opening 27; at least one dispensing device 11 sealingly connected to said opening 27, consisting of a hollow body, mostly cylindrical, divided into at least one upper chamber 24, communicating with the interior of said container 10 through at least one opening 14, and at least one lower chamber 12, communicating with said upper chamber 24 through at least one orifice 29 and with the exterior of said container 10, through at least one duct 17. [0082] . With reference to figures 1 to 5, these show a dispensing bottle 20 consisting of a container 10, assimilable to a common bottle for fluid substances, having a hollow body, optionally of a shape favouring the grip, provided with an opening 27 which is firmly and sealingly connected, or in other terms, is fluid-seal connected, to a dispensing device 11 which, being introduced therein through said opening 27, is mostly inside said container 10. [0083] . As shown in figures 3 and 9, said dispensing device 11 consists of a hollow body, mainly cylindrical, divided into two chambers of which one is upper, or loading chamber or measuring chamber 24, and one is lower or collecting chamber 12, communicating with one another through an orifice or inlet opening 29 to the collecting chamber.

[0084] . In the side wall of said upper chamber 24 there is obtained, at a suitable height, an opening or loading opening 14 which puts it into communication with the interior of said container 10.

[0085] . Said lower chamber 12 communicates with the outside of said container 10 through a duct or output duct 17. [0086] . With reference to figures 11, 14, 17, 18 and 19 it can be noted that the constituent elements described above are mostly present, even though realised in different ways, in other embodiments of dispensing device. [0087] . As shown in figures 6 to 19, several embodiments of dispensing device for bottle having the features just described may be obtained by connecting, every time, two components having suitable shape and size, identifiable with a tank 30 and with a cap 28.

[0088] . In one of the possible embodiments, with reference to figure 8, tank 30 consists of a hollow body, mainly cylindrical, of appropriate cross dimensions, for being inserted into opening 27, which at the top exhibits an input opening 29 to the collecting chamber and an output opening or outlet 25. [0089] . Tank 30 is sealingly or fluid-seal connected to a cap 28 consisting, as shown in figures 6 and 7, of a hollow body, assimilable to a common cap for bottles, provided with a connecting device 26 (as a non-limiting example, snap-wise or screw-wise) suitable for firmly and sealingly connecting it to opening 27 of container 10, which may conveniently exhibit a closing cap 16, as shown in figure 2.

[0090] . Said cap 28 is delimited at the top by a surface 15, as a non-limiting example, level, exhibiting a hole or dispensing opening 18 wherein on the hollow side, a duct or output duct 17 of suitable length extends; laterally, from a wall wherein at a suitable height there is obtained a loading opening 14. [0091] . The assembly between said tank 30 and said cap 28 may be favoured by a device 32, as a non-limiting example, joint-wise.

[0092] . As shown in figure 9, when tank 30 and cap 28 are properly assembled, the lower opening of duct 17 matches the upper output opening 25 of tank 30, thus connecting the lower chamber 12 to hole 18 and therefore to the exterior; conveniently, an entrance collar 13 may facilitate such connection, making it reliable and, advantageously, sealed.

[0093] . A tank for dispensing bottle like the one just described may be obtained, as a non-limiting example, in a thermoplastic resin by an injection and blowing technique. [0094] . Figure 10 shows another preferred embodiment of a tank for dispensing bottle, which may be obtained, as a non-limiting example, in a thermoplastic resin by an injection and moulding technique.

[0095] . As is shown, opening 25 mainly exhibits the same shape and the same size as a cross section of the tank itself.

[0096] . The dispensing device for bottle according to the invention obtained by correctly assembling the cap of figure 6 with the tank of figure 10 is shown in figure 11. [0097] . In this case, the orifice 29 for the communication between the upper chamber 24 and the lower chamber 12 consists of the portion of opening 25 not closed by duct 17.

[0098] . As regards the operation of a dispensing bottle, with reference to figures 3 and 5, let's assume that said bottle 20 is in vertical position, as shown in figure 3, that container 10 contains a certain amount of product and that both the upper 24 and the lower 12 chambers of the dispensing device 11 are empty.

[0099] . This condition may be achieved, as a non-limiting example, by filling container 10, keeping it in vertical position, and then mounting the dispensing device 11 thereon.

[00100] . As shown in figure 5, by moving said bottle 20 to an inclined position, assimilable to that generally taken by a common bottle when its contents are poured, the only possible outlet for the product contained in container 10 is that indicated by line 21, passing through opening 14, going up the upper chamber 24 up to flowing through orifice 29, to enter duct 17.

[00101] . Once this point is reached, the product may run into said duct 17 and pour through hole 18. On the other hand, going into the upper chamber 24, once it reaches a level close to line 19, the fluid completely blocks opening 14, thus preventing the air contained in said chamber 24 from transferring into container 10 for replacing the fluid poured therefrom. [00102] . A situation of stagnation is actually reached, wherein the fluid, once it has reached a level approximately indicated by line 19, below the connection between duct 17 and the lower chamber 12, stops transferring to the upper chamber 24, remaining balanced, without coming out of bottle 20, and occupying the volume indicated, by way of a non-limiting indication, by the dotted zone.

[00103] . By returning the bottle to the vertical position (wherein, as a non-limiting example, it may be placed on a shelf) , the amount of product contained at this point into the upper chamber 24 pours through orifice 29 into the lower chamber 12.

[00104] . Upon the next use, when bottle 20 is inclined again, said amount of product now contained into the lower chamber 12, corresponding to a dose, enters duct 17 and is dispensed from the bottle following a path illustrated, by way of a non-limiting indication, by line 22. [00105] . The remaining product contained in the bottle, on the other hand, will follow the same steps illustrated above, entering the upper chamber 24 until it stops at a level indicated, approximately, by line 19, without coming out of bottle 20 and occupying the volume shown, by way of a non-limiting indication, by the dotted zone. [00106] . By moving the bottle again to the vertical position, such fluid will pour into the lower chamber 12, thus preparing the bottle for a new dispensing, and so on. [00107] . The relative capacity of the upper 24 and lower 12 chambers of the dispensing device 11, keeping the filling of said lower chamber 12 regular, ensures a regular and reliable dispensing. [00108] . Figures 12 and 13 respectively show another embodiment of cap and another embodiment of tank for dispensing bottle. A difference between this solution and those illustrated above consists in that in this case, the side wall of the upper chamber 24 is obtained integral with tank 30 rather than with cap 28. This solution has the advantage of making the assembly of the components with container 10 especially simple. Tank 30, in fact, exhibits a collar 23 which, resting on the edge of opening 27, is blocked, as a non-limiting example, by pressure, by cap 28, in turn provided with a suitable device 26 adapted for firmly and sealingly connect it to said opening 27. [00109] . As it can be seen in figure 14, the dispensing device obtained by connecting the cap of figure 12 to the tank of figure 13 mainly maintains some of the major constituent features of that illustrated in figure 11. [00110] . Figure 16 shows a further embodiment of tank for dispensing bottle wherein, in addition to the lower chamber 12, there are integrally obtained the side wall of the upper chamber 24, duct 17, and device 26 for the connection to tank 10, in this non-limiting case shown by a swelling by pressure-coupling.

[00111] . As it can be seen, in this embodiment orifice 29 is obtained in the side wall of duct 17. [00112] . In this case, the cap is reduced to the portion that forms the upper surface 15, wherein there is obtained hole 18, as shown in figure 15. The connection between the two elements may be favoured by a connection device, also in this case represented, as a non-limiting example, by a joint-wise system. The dispensing device for bottle according to the invention obtained by connecting the cap of figure 15 to the tank of figure 16 is shown in figure

17.

[00113] . Figures 18 and 19 show further embodiments of dispensing devices for bottles obtained by connecting caps and tanks having some features differing from those described so far. In particular, in the embodiment shown in figure 19, the connection between the lower chamber 12 and duct 17 is obtained with the aid of a connecting element 31, also functioning as conveying element.

[00114] . The same figures show the constituent functions carried out by the different elements, as these are identified with the same numbering used for the previous cases. [00115] . The embodiments of dispensing bottle described above are well suited, as a non-limiting example, for the manufacture of the container and some types of tanks in thermoplastic resins (for example PET or polypropylene) by an injection and blowing technique, in a single piece; of other types of tanks and of various types of cap, in thermoplastic resins as well (for example polypropylene) by injection and moulding techniques, each in a single piece and with relatively simple moulds.

[00116] . It is clear that the embodiments of dispensing bottle according to the invention illustrated above are only some of the possible ones.

[00117] . In accordance with a further embodiment, the output duct 17 extends a little inside cap 28 relative to the upper surface 15, whereas the entrance collar 13 extends, relative to the connecting edge between said cap 28 and tank 30, by the length required for reaching said duct 17. This embodiment allows setting up the device for two different uses. More in detail, an operation similar to that of the other embodiments of dispensing device, when cap 28 and tank 30 are correctly assembled to one another, and an operation similar to that of a conventional bottle, by assembling only cap 28 onto container 10. In this second case of use, the reduced size of the output duct 17 advantageously favours, for this embodiment, the full emptying of the bottle (figures 20 to 22) .

[00118] . The features of the dispensing bottle as well as the relevant advantages are clear from the above description, and we may mention: [00119] . - possibility of use with a single hand; [00120] . - reduced overall dimensions;

[00121] . - regular and reliable dispensing;

[00122] . - simple and intuitive use;

[00123] . - construction and assembly simplicity. [00124] . Finally, it is clear that several changes and variations can be made to the dispensing bottle thus conceived, all falling within the invention; moreover, all details can be replaced with technically equivalent elements. In the practice, the materials used, the assembly technologies as well as shapes and sizes, can be whatever, according to the technical requirements.

[00125] . A man skilled in the art may make several changes, adjustments and replacements of elements with other functionally equivalent ones to the preferred embodiment of the dispensing device and bottle described above, in order to meet specific and incidental needs, without departing from the scope of the following claims.
