Description

DESCRIPTION "Distributor for powder alimentary product" [0001] . The subject of the present invention is a distributor for powder alimentary product. [0002] . More particularly, the invention relates to a distributor for sugar or similar. [0003] . There are known distributors for alimentary product, for example sugar, which require the distributor to be inverted to deliver the product. In some cases, known distributors are capable of delivering a substantially predetermined quantity of product but nevertheless require inversion of the distributor or the provision of complex movable structures the effectiveness of which is greatly limited in the case of powder product such as sugar, for example.

[0004] . From what has been stated above it can be seen that there is a requirement to have a distributor for powder alimentary product which allows delivery of the product in an upright position without the need for inversion, while maintaining a simple structure and uncomplicated operation. A further requirement is to have an effective distributor particularly when closed to prevent unwelcome escapes of product and, where appropriate, a distributor capable of always delivering the same quantity of product. [0005] . The scope of the present invention is to devise and make available a distributor for powder alimentary product which meets the above requirement and at the same time eliminates the disadvantages cited with reference to the known technology. [0006] . This scope is achieved by means of a distributor for powder alimentary product according to claim 1. [0007] . Other characteristics and advantages of the distributor for powder alimentary product according to the invention will become clear from the following description of preferred examples of embodiment, given purely by way of non-limiting example, with reference to the appended drawings, in which: [0008] . figure 1 shows a view in longitudinal section of a distributor for powder alimentary product according to the present invention, in a first operating condition; [0009] . figure 2 shows the distributor in figure 1 slightly in perspective, [0010] . figure 3 shows a view in longitudinal section of the distributor for powder alimentary product in figure 1, in a second operating condition; [0011] . figure 4 shows the distributor in figure 3 slightly in perspective; [0012] . figure 5 shows an enlarged detail of figure 4 from a different angle; [0013] . figure 6 shows a perspective view from the underneath of the distributor according to the present invention; 5 [0014] . figure 7 shows a perspective view of a part of the distributor according to the present invention; [0015] . figure 8 shows a perspective ^"view in longitudinal section of a part of the distributor according to a possible embodiment of the present

10 invention; [0016] . figures 9-13 show some steps in the assembly of the distributor according to the present invention. [0017] . With reference to the above-mentioned drawings, the number 10 indicates as a whole a distributor for

15 powder alimentary product, in particular sugar, according to the present invention. [0018] . The number 12 indicates an outer casing capable of forming a reservoir 14 to contain the alimentary product .

20 [0019] . According to a possible embodiment, the casing 12 comprises a centre portion 12a, a cover 12b and a base portion 12c. [0020] . With reference for example to a closed position of the distributor 10, the base portion is capable of

25. resting on a surface forming a lower portion of the distributor, while the cover forms an upper portion of the distributor. In what follows, the terms lower and upper will therefore be used with reference to a closed position in which the distributor is resting on a substantially horizontal surface. Nevertheless, in normal conditions of use, the distributor 10 is also capable of being kept in a position such that the base portion forms a lower portion of the distributor while the cover forms an upper portion. [0021] . Advantageously, the centre portion and the base portion have a symmetrical form relative to a longitudinal axis 16, for example a cylindrical or slightly truncated cone configuration. Considering the distributor 10 resting on a substantially horizontal plane, the longitudinal axis 16 is arranged substantially vertically. In other words, where F indicates a direction of discharge of the product by gravity, this direction is substantially parallel to the longitudinal axis 16 of the distributor resting on a substantially horizontal plane.

[0022] . According to the embodiment shown in the drawings, for example, the centre portion 12a and the cover 12b are screwed together while the centre portion 12a and the base portion 12c snap together, for example by the connection between a groove 18 made in the outer surface of the centre portion 12a and a rib 20 made on the inner surface of the base portion 12c. According to a possible embodiment, the centre portion 12a comprises an extension 21 which extends below the point of connection with the base portion 12c and inside the latter. [0023] . According to a possible embodiment, the distributor 10 comprises a handle 22. For example, the handle 22 extends from the cover 12b and is preferably made in one piece with the cover. In the embodiment illustrated in the drawings, the handle 22 has a free end.

[0024] . According to a possible embodiment, the casing 12, preferably the cover 12b, has an opening 24 capable of receiving an operating lever 26 which has a first end 26a external to the casing 12 and a second end 26b internal to the casing and capable of being arranged for example in an upper area of the reservoir 14. According to a possible embodiment, the second end 26b of the operating lever 26 is in the form of a fork while the first end 26 has a surface which the user bears upon to effect distribution of the product. [0025] . In the case in which the handle is provided, the opening 24 is advantageously made in an upper portion of the handle. [0026] . According to a possible embodiment, the operating lever 26 is pivoted on the casing 12 and in particular on the cover 12b through the opening 24. [0027] . According to a possible embodiment illustrated in figures 1-4, an insert 28 is inserted in the casing 12, preferably in the handle 22 so as to produce a support for a lower portion of the operating lever 26. Advantageously the insert 28 forms a seal capable of preventing the product from escaping through the opening which houses the operating lever 26. In a possible embodiment, the insert 28 is housed in a shell 30 capable of being fitted into the casing 12.

[0028] . According to a different embodiment, illustrated in figure 8 for example, the insert is avoided by reducing as far as possible the opening through which the operating lever 26 passes. [0029] . According to a possible embodiment, the cover 12b is formed so as to produce a seating 32, for example cylindrical, which extends coaxially with the longitudinal axis 16 and is open towards the inside of the reservoir. Advantageously the seating 32 is obtained by means of a wall 34, for example cylindrical, which extends towards the inside of the reservoir from an upper portion of the cover. [0030] . A rod 36 is fitted slidably inside the reservoir along its own longitudinal axis, preferably coinciding with the longitudinal axis 16 of the distributor. [0031] . According to a possible embodiment, the rod 36 comprises an upper portion 38 capable of interacting with the second end of the operating lever 26. Advantageously, In the case in which the operating lever 26 has a second end 26b made in the form of a fork, the portion 38 of the rod 36 has two cavities capable respectively of receiving the prongs of the fork-shaped end 26b (figure 7) . [0032] . According to a possible embodiment, the upper portion 38 of the rod has an annular surface 40 capable of constituting a seating for spring means, preferably a spring 40 placed between the rod and the cover. The spring is preloaded so as. to keep the rod away from the cover, that is to say downwards with reference to the drawings . [0033] . According to a possible embodiment in which the seating 32 is provided, the upper portion 38 of the rod 36 has a guide length 44 capable of being inserted into the seating 32 and of sliding in it during translational movement of the rod. In other words, the seating 32 is advantageously shaped so as to form a guide for the rod to slide along its own longitudinal axis during operation of the distributor 10. [0034] . According to a possible embodiment in which the seating 32 is provided, the wall 34 which forms this seating is capable of accommodating the spring 42 externally for example. [0035] . The number 46 indicates a centre portion of the rod which extends along the longitudinal axis 16 from the upper portion 38 of the rod and away from the cover. Advantageously the centre portion 46 of the rod has a threaded upper end 46a capable of being screwed into a threaded seating 38a made in the underneath of the upper portion 38. [0036] . According to a possible embodiment, the centre portion 46 of the rod 36 has a guide portion, for example a portion 48 thickened in a direction transverse to the longitudinal axis 16. According to a possible embodiment, the thickened portion 48 has a groove 50 capable of receiving a radial sealing component (O-ring) . [0037] . According to a possible embodiment, the centre portion 46 of the rod 36 comprises a containing wall 52 arranged at the opposite end relative to the upper portion 38. As will be described subsequently, the containing wall 52 forms a piston or movable shutoff device forming part of shutoff means arranged inside the reservoir. [0038] . Advantageously, the containing wall 52 internally forms a collecting volume or chamber and is open at the bottom. Preferably the containing wall 52 is constituted by a side wall 52a of cylindrical shape, open at the bottom, arranged to be coaxial with the longitudinal axis of the rod and provided with an upper base 52b which extends from the lower end of the centre portion 46 of the rod 36. [0039] . Preferably the containing wall 52 is made in one piece with the centre portion 46 of the rod.

[0040] . The number 54 indicates at least one opening made through the thickness of the containing wall 52, in particular of its side wall. Advantageously four openings are provided, 90° apart, although a different number and distribution may be provided. The at least one opening 54 forms an inlet for the product to the inside of the containing wall 52 or of the collecting chamber. With reference to the collecting chamber, each opening 54 forms an inlet arranged in a transverse position relative to a direction of discharge F of the product by gravity. In other words, each inlet to the collecting chamber is arranged in a lateral containing wall of this collecting chamber so that the product has to flow in a direction with a component, preferably predominant, in a direction perpendicular to. the longitudinal axis 16 or to the direction of discharge of the product by gravity. [0041] . According to a possible embodiment, the openings 54 are arranged so as to leave an annular length 55 of the containing wall 52 arranged below the openings. This annular length 55, if present, forms more precisely the movable shutoff device as will be described in what follows . [0042] . According to a possible embodiment, the openings 54 are inclined downwards and towards the collecting chamber through the thickness of the containing wall, that is in a longitudinal section or a section containing the longitudinal axis of the rod. [0043] . According to a possible embodiment, the rod 36 comprises a closure element 56 arranged below the centre portion of the rod. Advantageously, the closure element comprises a small plate 58 connected to a stem 60 capable of being connected to the centre portion of the rod so that the closure element 56 is in the open position when the movable shutoff device is also in the open position and vice versa.

[0044] . In a possible embodiment, the stem 60 is force- fitted into a seating 62 made centrally at the lower end of the centre portion of the rod. Advantageously, the closure element 56 is arranged to be coaxial with the rod . [0045] . In the case in which the containing wall 52 is provided, the stem 60 extends centrally through the volume formed by the containing wall, that is through the collecting chamber. [0046] . The number 64 indicates a base of the reservoir 14 capable of closing the reservoir at the bottom. According to a possible embodiment, the base 64 is advantageously inserted between the centre portion 12a and the base portion 12c remaining locked in position or fitted in between them. Advantageously, a perimeter rib 66 may be provided which extends upwards from the base

64 and is capable of being arranged internally in contact with the inner surface of the centre portion 12a of the casing 12 and being centred with it. Preferably the perimeter rib 66 is capable of being arranged internally in contact with the extension 21 of the centre portion

12a. [0047] . According to a possible embodiment, the base 64 extends radially beyond the perimeter rib 66 to form a stop portion for the lower end of the centre portion 12a of the casing 12 and in particular for the extension 21. [0048] . According to a possible embodiment, a projection 67 extends downwards from the base 64. [0049] . According to a possible embodiment, a hollow body 68 extends inside the reservoir coaxially with it. For example the hollow body 68 is capable of forming a guide element for the containing wall 52 or for the rod 36. [0050] . Advantageously the hollow body 68 comprises a first wall 70 capable of receiving the containing wall 52. This first wall is open at the bottom and, according to a possible embodiment, extends slightly below the base 64 for a length 71. Preferably the first wall 70 is cylindrical, coaxial with the longitudinal axis 16 and its internal dimensions are such as to constitute a guide body for the containing wall 52.

[0051] . Advantageously the first wall 70 is combined with the base 64, preferably being made in one piece with it.

[0052] . At least one opening 72 is made in the thickness of the first wall 70. Preferably, four openings arranged 90° apart are provided, although a different number and distribution may be provided. The at least one opening 72 forms an inlet for the product to the inside of the containing wall 52 or of the collecting chamber, cooperating with an opening 54 made through the containing wall 52. [0053] . According to a possible embodiment, the openings 72 are arranged so as to adjoin the base 64 at the bottom. [0054] . According to a possible embodiment, the openings 72 are inclined downwards and towards the collecting chamber through the thickness of the first wall, that is in a longitudinal section or a section containing the longitudinal axis 16. [0055] . According to a possible embodiment, the hollow body 68 comprises a second wall 74 capable of receiving internally the centre portion 46 of the rod 36 and substantially coaxial with it. Preferably the second wall 74 is cylindrical and its internal dimensions are such as to constitute a guide body for the rod 36 and in particular for the thickened portion 48.

[0056] . Advantageously the second wall extends at the top to the first wall and is made in one piece with it .

[0057] . According to a possible embodiment, the base portion 12c comprises a locking element 76 capable of bearing against the base 64 to keep it fitted in between the base portion 12c and the centre portion 12a of the casing 12. Advantageously the locking element 76 comprises a ledge which extends from the base portion 12c transversely to the longitudinal axis 16 towards the inside of the base portion. [0058] . In the case in which the base 64 is provided with the projection 67, the locking element 76 is provided with a corresponding opening 78 capable of receiving this projection to line up the threads of the distributor. [0059] . According to a possible embodiment, the base portion 12c comprises a bottom 80 in which a further opening 82 is made. The dimensions of the further opening 82 are such as to allow it to be closed by means of the closure element 56, if present. This further opening 82 is arranged higher up than the collecting chamber according to the direction of discharge of the product by gravity.

[0060] . The bottom 80 preferably has a substantially truncated-cone shape, inverted, in which the opening 82 is made in the smaller diameter portion. According to a possible embodiment, the bottom 80 is made in one piece with the base portion 12c, for example extending continuously from the ledge forming the locking element 76. Ribs 83 arranged for example 120° apart stiffen the bottom 80 and connect it to the wall of the base portion 12c.

[0061] . According to a possible embodiment, the casing 12 comprises a bottom portion 84, for example conical or truncated-cone shaped with the vertex upwards. Advantageously the bottom portion 84 is arranged centrally relative to the casing 12, for example coaxial with the longitudinal axis 16. [0062] . According to a possible embodiment, the bottom portion 84 is arranged so as to cooperate with the containing wall 52, in particular with the annular length 55, in the closed position of the distributor. In other words the transverse dimensions of the containing wall 52 and of the bottom portion 84 are such as to allow contact between them when the distributor is in the closed position. [0063] . Advantageously, the bottom portion 84 is fitted to the base portion 12c. For example the bottom portion is integral with one or more spokes 86 which extend from a ring 88 capable of being housed in a seating made in the bottom 80 of the base portion 12c. [0064] . According to a possible embodiment, the bottom portion 84 is arranged at a specified distance from the base 64 or from the containing wall 52 when arranged in a raised position. In particular, the bottom portion 84 is arranged at a specified distance from the first wall 70 and still more in particular from the length 71, if present. In other words, the relative position of the bottom portion 84 and of the base 64 (first wall 70 or length 71, if present) is such as to leave a passage 89 for the product when the distributor is in the open position. This passage 89 forms an outlet through which the product is discharged from the reservoir 14, and in particular from the collecting chamber, to the outside. The containing wall 52, that is with the movable shutoff device, is capable of cooperating with this outlet to open or close it.

[0065] . According to a possible embodiment, the shutoff means arranged inside the reservoir comprise the first wall 70, the containing wall 52, both acting as a piston or movable device and forming a collecting chamber, and the bottom portion 84.

[0066] . According to a possible embodiment, when the closure element 56 is provided, the bottom portion 84 has a central passage 90, capable of receiving the closure element 56 and in particular the stem 60 and of allowing it to slide.

[0067] . With reference to figures 9-13, the assembly of the distributor 10 will be described below.

[0068] . Figure 9 illustrates a first step in the assembly in which the closure element 56 and in particular its stem 60 is threaded through the central passage 90 of the bottom portion 84. The end of the stem 60 is pressed into the seating 62 of the centre portion 46 of the rod.

[0069] . Figure 10 shows a further step in the assembly of the distributor in which the centre portion 46 of the rod is inserted into the hollow body 68 of the base 64. The drawing shows a rib 94 on the rod and a corresponding groove 96 in the hollow body forming a guide capable of allowing sliding only between the two above-mentioned elements . [0070] . Figure 11 illustrates a subsequent step in the assembly in which the set of parts comprising the centre portion 46 of the rod, the bottom portion 84, the closure element 56 and the hollow body 68 of the base 64 is threaded onto the base portion 12c of the casing 12. The projection 67 is threaded into the opening 78 to line up the threads of the distributor. [0071] . Figure 12 illustrates the fitting of the centre portion 12a of the casing 12, preferably produced from transparent material, onto the base portion 12c. The drawing illustrates two locating features 98 respectively arranged on the centre portion 12a and on the base portion 12c. In a first step in the assembly, the centre portion 12a is threaded axially onto the base portion 12c so that the two locating features 98 are lined up. Next the upper portion is rotated clockwise until it locks .

[0072] . Figure 13 illustrates the step of filling with sugar or the alimentary product in general, through the upper opening in the centre portion 12a. During this step, the rod is pressed downwards to keep the distributor closed. The maximum level of the sugar is indicated by the height of the hollow body 68. Finally the cover 12b is screwed on to the centre portion 12a to obtain the assembled distributor. [0073] . When the sugar is used up, the cover 12b is unscrewed, the centre portion 12a is filled with sugar and the cover is closed again. [0074] . In general terms, the distributor for alimentary product according to the present invention comprises shutoff means arranged inside the reservoir 14 and comprising a movable shutoff device which in a closed position prevents discharge of the product to the outside and in an open position allows discharge of the product to the outside by gravity. The direction of discharge of the product by gravity is indicated by F, assuming that the position of the distributor illustrated in the drawings is a vertical position corresponding to the normal position of use of the distributor. [0075] . According to a possible embodiment, for example illustrated in the drawings, the shutoff means comprise the first wall 70, or more generally the hollow body 68, the containing wall 52 and the bottom portion 84.

[0076] . Advantageously the movable device is embodied by means of a piston comprising at least one portion capable of preventing discharge of the product to the outside by gravity. In an example of embodiment illustrated for example in the drawings, this movable device or piston comprises the containing wall 52 and in particular the annular length 55. Advantageously the movable shutoff device is capable of translational movement in a direction substantially parallel to the direction of discharge of the product by gravity, assuming a normal position of use of the distributor. [0077] . With reference to a general aspect of the invention, the shutoff means comprise at least one inlet for the product to a collecting chamber and at least one outlet for the product to the outside of the collecting chamber. The inlet to the collecting chamber is open when the movable device is in the closed position, that is in the position in which it closes the outlet for the product to the outside from the collecting chamber. The outlet from the collecting chamber is open when the movable device is in the open position, that is in the position in which the outlet from the chamber is open and in which the inlets to the chamber are closed.

[0078] . In particular, when the movable shutoff device is in the closed position and the inlet from the reservoir to the collecting chamber is open, the movable shutoff device is capable of closing the outlet from the collecting chamber. The latter is then in communication with the reservoir only. [0079] . Advantageously, the at least one inlet for the product from the reservoir to the collecting chamber is arranged in a transverse position relative to the direction of discharge of the product by gravity. [0080] . According to an advantageous example of embodiment of the present invention, the collecting chamber is delimited substantially by the containing wall 52 forming the movable shutoff device described above. In particular when the distributor is in the closed position (figures 1 and 2) , the collecting chamber is delimited by the movable device comprising the containing wall 52 and by the bottom portion 84 with which this containing wall cooperates. In other words, the movable shutoff device delimits the collecting chamber laterally, with respect to the direction of discharge of the product by gravity. In the example illustrated in the drawings, the collecting chamber is delimited laterally by the containing wall 52. [0081] . The above-mentioned inlet for the product to the collecting chamber comprises the opening 54 (or the openings 54) made in the containing wall 52. In the embodiment illustrated, said inlet for the product to the collecting chamber also comprises the opening 72 (or the openings 72) made in the first wall 70. In fact the openings 72 in the first wall 70 and the openings 54 in the containing wall 52 are capable of being substantially lined up to allow the product to pass to the collecting chamber when the movable device is in the closed position. [0082] . Advantageously, both the openings 72 in the first wall 70 and the openings 54 in the containing wall 52 are arranged so as to produce a transverse inlet with respect to the direction of discharge of the product by gravity indicated by F. In other words, the product does not reach the collecting chamber from an opening made in an upper portion of the chamber but from a side portion for example with reference to the longitudinal axis of the distributor. In still other words, the shutoff means comprise at least one inlet to the collecting chamber arranged so that the product enters from the side into the collecting chamber, flowing in a direction having a component arranged in a direction perpendicular to the longitudinal axis 16 (or in any case to the direction of discharge by gravity) .

[0083] . According to a possible embodiment of the invention, a further movable shutoff device may be provided, capable of closing or opening the at least one inlet from the reservoir to the collecting chamber depending on the respectively open or closed position of the outlet from the collecting chamber. The further movable shutoff device may advantageously be capable of closing and opening the inlet to the collecting chamber by translational movement between a closed position and an open position in a direction parallel to the inlet . For example the further movable shutoff device comprises a wall substantially parallel to the inlet, preferably forming a guillotine closure of the inlet. In the embodiment illustrated in the drawings, the movable shutoff device and the further movable shutoff device coincide structurally. This is because a single movable shutoff device is provided, for example formed by the annular length 55 and capable of selectively closing the inlet from the reservoir to the collecting chamber and the outlet from the collecting chamber to the outside.

[0084] . According to an advantageous example of embodiment as described above, the outlet for the product to the outside from the collecting chamber comprises the passage 89 between the bottom portion 84 and the base 64 (or the containing wall 52 when in the open position) , The annular length 55 bears against the bottom portion 84 and extends in height at least for the length covered by the passage 89 so as to close it. In other words, the annular length 55 forms a movable shutoff device capable of closing the passage 89 when the distributor is in the closed position. [0085] . A description is given below of the operation of a distributor according to the present invention, for example as illustrated in the drawings. [0086] . The reservoir 14 to contain the alimentary product is substantially formed by the centre portion 12a of the casing and by the base 64 combined with the centre portion. To fill the reservoir 14, the cover 12b is unscrewed, giving access to the inside of the centre portion 12a. [0087] . Figures 1 and 2 illustrate a closed position of the distributor 10, that is in which the movable shutoff device, for example comprising the containing wall 52, is in a closed position and prevents the product from coming out of the collecting chamber for example substantially formed by the containing wall. In other words, the annular length 55 rests on the bottom portion 84 and closes the passage 89. [0088] . The openings 54 through the containing wall 52 and the openings 72 through the first wall 70 form the inlets of the shutoff means to the collecting chamber. In the closed position, the openings 54 through the containing wall 52 and the openings 72 through the first wall 70 are lined up and therefore the inlet to the collecting chamber is open and allows the product to flow from the reservoir to the collecting chamber. [0089] . Because of the advantageous form and arrangement of the above-mentioned inlets, the flow of the product from the reservoir to the collecting chamber is substantially transverse to the direction of discharge of the product by gravity. In other words, the product enters the collecting chamber not from above but from a side portion so that the flow F' of the product at the inlets to the collecting chamber has a component, preferably predominant, arranged in a direction perpendicular to the longitudinal axis 16 or to the direction of discharge by gravity F. In other words, the arrangement of the inlet to the collecting chamber forces the flow of the product to follow a winding course with at least one change of direction between the vertical direction and the direction F¹ at the inlet.

[0090] . In the example illustrated, the collecting chamber is formed by the containing wall 52 and by the bottom portion 84. With reference to figures 1 and 2, that is to the closed position of the distributor, the containing wall 52 and the bottom portion 84 are in contact and the collecting chamber communicates with the reservoir only. [0091] . In the case which the closure element 56 is provided, this is in contact with the bottom 80 to close the opening 82 towards the outside.

[0092] . Figures 3-5 illustrate an open position of the distributor 10. The changeover from the closed position to the open position is obtained by raising the movable shutoff device and consequently the rod 36 by means of the operating lever 26. In other words, by taking hold of the distributor 10, the user presses downwards the end 26a of the operating lever external to the distributor. The end 26b of the operating lever rises, pulling the rod 36 with it against the thrust exerted by the spring 42. The guide length 44 undergoes translational movement guided within the seating 32, and the thickened portion 48 undergoes translational movement, guided within the second wall 74. [0093] . The containing wall 52, and in particular the annular length 55 or movable shutoff device is raised, freeing the passage 89 and therefore opening the outlet of the collecting chamber. The product can thus be discharged to the outside and pass through the openings left free by the spokes 86. The arrangement of the inlet and outlet of the collecting chamber forces the product to follow a winding course, illustrated in figure 3 for example, impeding the passage from the reservoir to the collecting chamber in the brief interval in which the inlet to the collecting chamber is closing. [0094] . In the case in which the closure element 56 is provided, this rises with the rod and with the movable shutoff device to open the opening 82 and allow further discharge of the product. [0095] . The upward translational movement of the rod and therefore of the movable shutoff device (annular length 55) puts the openings 54 in the containing wall 52 and the openings 72 in the first wall 70 out of line with each other. In particular the movable device is located in a position in which it faces the openings 72 in the first wall 70 preventing the product from coming out of the reservoir to the collecting chamber. In other words, when the distributor is in the open position, the collecting chamber communicates only with the outside through the outlet formed by the passage 89.

[0096] . The containing wall 52, and in particular the annular length 55, therefore also forms a movable shutoff device capable of translational movement inside the first wall 70 to open or close the inlet to the collecting chamber. In particular the annular length 55 forms a guillotine closure of the inlet to the chamber. In other words, the movable shutoff device capable of closing and opening the inlet from the reservoir to the collecting chamber comprises a wall formed for example by the annular length 55 substantially parallel to the inlet. This shutoff device undergoes translational movement between a closed position and an open position in a direction parallel to the inlet. [0097] . In accordance with the above, the shutoff means form a collecting chamber capable of being made to communicate selectively with the reservoir and with the outside. The term selectively is intended to mean the condition by which the outlet of the collecting chamber to the outside is closed when the chamber is communicating with the reservoir (inlet open) and vice versa. Advantageously this function is performed by a single movable shutoff device.

[0098] . The collecting chamber allows a substantially specified quantity of product to be drawn off- from the reservoir and discharged to the outside when required by the user. [0099] . From the above, it can be appreciated how the provision of a distributor according to the present invention allows the distributor to be used while kept in an upright position, eliminating the inverting or tilting required in state-of-the-art devices to cause the product to be discharged. Moreover, the provision of a collecting chamber with an inlet transverse to the direction of discharge of the product by gravity prevents the product from falling freely into the collecting chamber and at the same time provides more effective closure of the inlet when the outlet towards the outside opens. This is because when a transverse inlet is used, it is possible to produce a closure of this inlet in a direction parallel to the inlet, or a guillotine closure, which rapidly shuts off the flow of product into the collecting chamber.

[00100] . Moreover, the collecting chamber is effectively delimited in a lateral direction allowing a precise definition of the volume of product to be delivered.

[00101] . The arrangement of the inlet (or inlets) to the collecting chamber and where appropriate of the outlet

(or outlets) from the collecting chamber creates a winding flow of product with at least one change of direction relative to the vertical which allows the collecting chamber to be effectively closed when the outlet is opened.

[00102] . The present invention also enables the collecting chamber to be delimited laterally by means of the shutoff device itself so as to cut off more effectively the volume of product to be delivered.

[00103] . Moreover, from the above it is seen to be particularly advantageous to use a single shutoff device which selectively closes the inlet to the collecting chamber and the outlet from the collecting chamber, simplifying the structure and giving more effective operation.

[00104] . Because of the provision of an operating lever and where appropriate of a rod, it is possible to operate the distributor from the outside, guaranteeing delivery of the product with the dispenser in an upright position.

[00105] . Delimiting a collecting chamber with a lower bottom fixed relative to the casing of the distributor enables a specified volume of product to be delivered reproducibly and reliably. Its cone-shaped form allows the product to flow easily.

[00106] . The provision of a base portion distinct from the outlet of the product makes it possible to arrange a seating part of the distributor capable of keeping it in an upright position even in the closed position.

[00107] . Provision of a closure element distinct from the collecting chamber further increases the effectiveness when closing, preventing unwanted leakage of the product . [00108] . A further advantage of the distributor according to the invention lies in the unusual simplicity of its structure, enabling it to be produced at very modest cost .

[00109] . Clearly, variants and/or additions may be provided to what has been described and illustrated above . [00110] . As an alternative to what is shown in the drawings, the cover and the centre portion may be fixed together by means of a snap-on connection or other type of connection or may be produced as a single part. Also, the base portion may be fixed differently to the centre portion, for example by screw threading, or may be made in one piece with it. [00111] . The operating lever may interact differently with the rod and be fitted differently to the casing. Moreover the rod could be produced as a single unit or the various parts may be fitted together using different methods from those illustrated. For example the movable shutoff device produced by means of the containing wall 52 does not have to be in one piece with the centre portion of the rod. [00112] . The closure element 56 may be dispensed with or be produced differently from what is illustrated, for example made in one piece with the rod or screwed into it. In the case where the closure element 56 is dispensed with, in the open position of the distributor the product leaves the collecting chamber through the spokes 86 and comes out of the further opening 82 which is open in any case. Closure is achieved by lowering the movable shutoff device (containing wall 52) in contact with the bottom portion 84 while the further opening remains open. Alternatively, the bottom 80 in which an opening 82 is made may also be omitted or produced in a different configuration. [00113] . The hollow body 68 may be produced differently from what is illustrated, for example without a second wall guiding the rod or may be fitted directly to the casing (for example from above) . [00114] . According to a possible embodiment, independently of the other characteristics described above, the distributor for powder alimentary product according to the present invention comprises a reservoir to contain the product and shutoff means arranged inside the reservoir and comprising a movable shutoff device which in a closed position prevents discharge of the product to the outside of the reservoir and in an open position allows the product to be discharged to the outside of the reservoir by gravity. The shutoff means comprise at least one inlet for the product from the reservoir to a collecting chamber and at least one outlet for the product to the outside from the collecting chamber. The movable shutoff device is capable of closing the outlet from the collecting chamber in the closed position. [00115] . The shutoff means also comprise a closure element capable of closing a further opening in the distributor arranged higher up than the collecting chamber along the direction of discharge of the product by gravity. The closure element is in the open position when the movable shutoff device is also in the open position and vice versa. Advantageously the closure element is integral with the movable shutoff device. [00116] . In what follows, a description will be given of a possible embodiment, not shown, in which the elements in common with the embodiment illustrated in the drawings are indicated by the same reference numbers though there is no reference drawing. Contrary to what has been described above, the collecting chamber may be delimited laterally directly by the hollow body 68 and in particular by the first wall 70 provided with at least one opening 72 which forms the inlet from the reservoir to the collecting chamber. This inlet for the product is arranged in a transverse position relative to the direction of discharge of the product by gravity. The bottom portion 84, fixed to the casing 12, delimits at the bottom the collecting chamber as previously described. The outlet from the collecting chamber may also be formed by the passage 89 between the bottom portion 84 and the base 64. Inside the collecting chamber a movable shutoff device is provided, for example comprising a wall capable of sliding internally and in contact with the first wall 70. The movable shutoff device may for example be similar to just the annular length 55 of the movable device previously described. This movable shutoff device may be connected to the rod for example by means of spokes. The position of the openings 54 and of the passage 89 and their extension are such that the same movable shutoff device is capable of closing the inlet to the collecting chamber leaving the outlet open to allow the product to be discharged to the outside and, as a result of translational movement, to open the inlet to the collecting chamber while closing the outlet from it to allow discharge of the product from the reservoir to the collecting chamber. [00117] . Contrary to what has been described above, two movable shutoff devices may be provided. The movable shutoff device properly so-called is the one capable of allowing or preventing discharge to the outside, for example by opening or closing the outlet from the collecting chamber. In addition, a further movable shutoff device may be provided, structurally and functionally separate from the first, capable of opening or closing the inlet from the reservoir to the collecting chamber. Where appropriate both movable shutoff devices may be fitted to the same rod. [00118] . A person skilled in the art, for the purpose of meeting incidental and specific requirements, will be able to make numerous changes, adaptations and replacements of components in the preferred forms of embodiment of the distributor for powder alimentary product described above without thereby departing from the scope of the following claims. *** * ***
