CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    This patent application is a 371 U.S. National Application of PCT/IB2015/052399, filed Apr. 1, 2015, which claims priority to MI2014A000712, filed Apr. 16, 2014, the entire contents of which are incorporated herein by reference. 
     
    
     TECHNICAL FIELD 
       [0002]    The present invention refers to a container for delivering a prefixed number of products at a time and to a process for making said container. The container can find an application in the confectionery field, for example for defining portable dispensers adapted to deliver candies, mini chocolates and/or chewing-gums. Further, the container can be used in the pharmaceutical and cosmetic fields, for example for defining portable dispensers adapted to deliver tablets and/or pills. However, the container, object of the present invention, can find an advantageous application in all the fields providing to delivery, from a portable dispenser, a prefixed number of products, particularly one selected among a plurality housed in a compartment. Therefore, the above cited examples must be considered in a non limiting way because the products deliverable from the container, object of the present invention, can be of different kind, for example can comprise cigarettes. 
       BACKGROUND 
       [0003]    It is known how to make portable dispensers for small-sized products, such as tablets, pills and/or candies, configured for housing a plurality of said products and enabling to deliver them. Such dispensers are configured for enabling to deliver only one product at a time by activating a mechanism received inside the dispenser. The known containers are usually made, in all their parts, of plastic material and are obtained by molding. 
         [0004]    Generally, the known containers consist of two half-shells of plastic material coupable to each other for defining an inner compartment containing the products: the compartment exhibits an opening for enabling to delivery outside said products. A mechanism—made of different parts and different materials—is housed inside the container—the mechanism operates at the outlet for managing just the delivery of the products. By making reference to a particular case, the mechanism can consist of an extracting drawer, normally placed in a compartment closed condition; a metal spring configured for automatically bringing back the drawer from a delivery condition to a closed condition is associated to the extraction drawer. 
         [0005]    As hereinbefore discussed, containers adapted to delivery only one product at a time are already known; such containers are generally provided with a dosing chamber, directly defined on the drawer, which is adapted to carry only one product. De facto, the drawer, during the container closed condition, is completely housed inside the compartment: under such condition, the dosing chamber is adapted to house only one product. Upon activating the mechanism, the drawer is pushed outside the compartment: so only the product present in the dosing chamber can be delivered. 
         [0006]    Although the described containers enable to carry and delivery products, the Applicant has found that these latter are not devoid of disadvantages and are improvable under several aspects. First of all, it is useful to note that the structural complexity of such devices comprising several elements to define the delivery mechanism entail high costs; some parts must be necessarily obtained by molding and then coupled to the remaining parts, this process being uneconomical under several points of view increases the overall cost of the product. Further it is noted that for manufacturing containers destined to the food and pharmaceutical fields (for carrying food products and tablets), it is necessary to use food-grade plastics for plastics considered “noble” because they do not release substances altering the product container in the compartment. Such plastics exhibit certainly higher costs than the costs of the common plastics, which even more burden the overall costs of the containers. As hereinbefore described, also the particularly described delivery mechanism (drawer) is normally made of plastic material and is obtained by molding: such condition entails the same above cited disadvantages to the detriment of the container overall price. Further, it is noted that, following the step of molding the several details of the known container, it is necessary a step of assembling the semi-shells, drawer and spring; such operation is generally performed by hand (with consequent high investment costs for the automation) and provides to position the mechanism inside the semi-shells and close the container. The assembly is certainly not easily implementable because it provides to handle small-sized details and is time consuming. The assembly step surely complicates the manufacturing process with a hike of the manufacturing costs and consequently of the container overall costs.

     DETAILED DESCRIPTION 
     Container 
       [0143]    1 generally indicates a container or dispenser for delivering a prefixed number of products P at a time, particularly for delivering only one product P at a time. The present description will not specify the type of deliverable products P because such container  1  can be used for defining portable dispensers adapted to house/deliver different kind of products. For example, the container  1  can find an application in the confectionery field for dispensing candies, mini chocolates and/or chewing-guns. A further field of application can be represented by the pharmaceutical and cosmetic fields; de facto, the container can be used for delivering also tablets and/or pills. However, the above cited examples are considered in a non limiting way because the container  1 , object of the present invention, can find an advantageous application in all the fields providing to deliver, from a portable dispenser, a prefixed number of products; the products P can also comprise, in a non limiting way, cigarettes. 
         [0144]    As it is visible for example in  FIGS. 1-3 , the container  1  comprises at least one compartment  2  defining an inner volume  3  configured for housing a plurality of products P. The compartment  2  substantially represents the container  1  compartment adapted to house and support the plurality of products P before delivering these latter. The attached figures illustrate a non limiting configuration of the compartment  2  which exhibits a prismatic rectangular shape; however, it is not excluded the possibility of making a compartment of a different shape, for example trapezoidal or cylindrical. 
         [0145]    As it is visible, the compartment  2  extends, in a non limiting way, substantially along a prevalent development direction and exhibits a thickness lower than the length and width of the same. The compartment  2  is configured for exhibiting a minimum size, in this case, the thickness, greater than a transversal maximum size of each product P; the compartment  2  minimum size is, in a non limiting way, greater than 7 mm (the thickness S can vary and be suitably sized based on the product P and the quantity to deliver). Generally, the compartment  2  defines an inner volume greater than 20,000 mm 3 , particularly comprised between 40,000 and 100,000 mm 3 . Advantageously, the compartment  2  is made of sheet material and is obtained by folding. In a preferred but non limiting embodiment of the invention, the compartment  2  is made of paper sheet material (paper or paperboard); particularly, the used sheet material exhibits a grammage comprised between 100 and 500 gr/m 2 , particularly comprised between 200 and 400 gr/m 2 . As above described, the container, specifically the compartment  2 , can also be used for housing food or pharmaceutical and cosmetic products. Under such condition, it is advantageous to cover a compartment  2  inner surface by a plastic material coating, for example a film. The object of the coating is to define a barrier interposed between the compartment  2  and the plurality of products P; further, the coating is adapted to define a water and/or humidity barriers useful for avoiding the weakening and loss of structurality with consequent warping of the paper material forming the compartment  2 . Advantageously, the coating can be an extrusion coating on one (compartment  2  inner side) or both the sides (inner and outer surfaces of the compartment  2 ) of the paper material defining the compartment  2  with values which can, for example, vary between 10 and 50 gr/m 2  of the coating material (in other words polyethylene). The coating plastic material can be for example selected among the following materials: LDPE, HDPE, PP, PE. 
         [0146]    As it is visible in  FIGS. 2, 3 and 6 , the container  1  comprises at least a volume of passage  4  exhibiting at least one outlet  5  configured for enabling to supply the products P outside the container  1 . The volume of passage  4  is substantially configured for receiving one or plural products P from the compartment  2  and guiding them towards the outlet  5  for enabling to deliver them towards the outer environment. The volume of passage  4  substantially comprises a duct extending along a prevalent development direction Y (see for example  FIG. 3 ) and flanking the compartment  2 . In a preferred but non limiting embodiment of the invention, the volume of passage  4  is integrally joined to the compartment  2  to form a single detail; in such condition, the duct and compartment advantageously share the same partition lateral wall. 
         [0147]    The duct of the volume of passage  4  extends beside the compartment  2 , parallelly to the prevalent development direction of this latter, between a first and second ends  4   a,    4   b;  the outlet  5  of the volume of passage is placed at the first end  4   a  ( FIG. 2 ). As it is visible for example in  FIGS. 2 and 6 , the duct of the volume of passage  4  comprises, at the first end  4   a,  a recess  15  extending along the duct prevalent development direction Y; the recess  15  defines a cut crossing the duct lateral wall which fluidically communicates the duct inner volume with the outer environment. More specifically, the recess  15  defines a through opening  16  at a container  1  lateral wall and delimited by a free edge  17  having a substantially “U” shape communicating with the outlet  5  of the volume of passage  4 . The free edge  16  substantially defines a duct perimetral edge portion: the concavity of the “U” shape of the free edge  16  faces away from the duct second end  4   b  ( FIGS. 2 and 6 ). 
         [0148]    More particularly, the duct flanks the compartment  2  so that a duct lateral wall directly contacts a compartment  2  lateral wall. From the geometrical point of view, the duct exhibits, in a non limiting way, a square prismatic shape; de facto, according to the duct cross section (section normal to the prevalent development direction Y), the duct defines a substantially square or rectangular shape. However, the duct can exhibit several shapes, for example a circular cross section tubular, elliptical, diamond or trapezoidal shapes (these configurations are not illustrated in the attached figures). 
         [0149]    Instead, with reference to the dimensional aspect of the volume of passage  4 , this latter defines an area of passage (surface extension of the duct cross section) greater than 200 mm 2 , particularly comprised between 250 and 500 mm 2 . Besides such area (area of passage of the products P through the duct) it is possible to evaluate the duct minimum transversal size, measured normal to the development direction Y of the same, which is greater than 10 mm, particularly is comprised between 15 and 25 mm. The duct minimum size is in this case representative, in a non limiting way, of the duct thickness; the duct minimum size—as the compartment  2  minimum size—is configured for granting the passage (sliding) of the products P inside the volume of passage  4 , therefore, this latter must be greater than a maximum transversal size of the products P. The attached figures illustrate only ducts of prismatic shape; however, it is not excluded the possibility of making ducts of a different shape, for example tubular, cylindrical, elliptical, trapezoidal or diamond shape. 
         [0150]    Advantageously, but in a non limiting way, the inner volume defined by the duct is smaller than the compartment  2  inner volume, because the volume  4  is only adapted to enable only one product at a time to exit; de facto, the duct inner volume is greater than 20,000 mm 3 , particularly is comprised between 30,000 and 80,000 mm 3 . It is possible to evaluate the duct inner volume also by the ratio of the compartment  2  inner volume; de facto, the ratio of the compartment  2  volume to the duct volume is greater than 1.5, particularly is comprised between 2 and 4. 
         [0151]    Advantageously, also the volume of passage  4 , as for the compartment  2 , is made of sheet material and is obtained by folding. In a preferred but non limiting embodiment of the invention, the volume of passage  4  (duct) is made of paper sheet material (paper or paperboard); particularly, the paper sheet material used for making the volume  4  exhibits the same characteristics of paper/paperboard used for making the compartment  2 . As hereinbefore described, in a preferred embodiment of the invention, the volume of passage  4  is integrally joined to the compartment  2 , in such configuration the sheet material used for making this latter is the same as the one used for forming the duct because of the definition of only one integrally joined detail. 
         [0152]    The used paper sheet material can exhibit a grammage comprised between 150 and 400 gr/m 2 , particularly comprised between 200 and 300 gr/m 2 . As hereinbefore discussed, the container  1  can also be used for housing food products or products of the pharmaceutical and cosmetic fields. In such condition, it is advantageous to cover a duct inner surface by a plastic material coating, for example a film. The object of the coating is to define a barrier adapted to prevent the products to contact the paper material; further, the film defines a water and/or humidity barriers useful for avoiding the weakening and the loss of structurality with subsequent warping of the paper material forming the duct. Advantageously, it is possible to define an extrusion coating on one (duct inner side) or on both sides (duct inner and outer surfaces) of the paper material defining the volume of passage  4  with values which can for example vary between 10 and 50 gr/m 2  of coating material (in other words polyethylene). The coating plastic material can be for example selected among the following materials: LDPE, HDPE, PP, PE. 
         [0153]    It is possible to observe in the attached figures (for example  FIGS. 3-5 ), that the container  1  further comprises a door  6  defining an opening  7  configured for communicating the compartment  2  with the volume of passage  4 . De facto, the opening  7  comprises a passage placed, in a non limiting way, substantially at the second end  4   b  of the volume of passage  4 ; the passage (opening) is defined on one or more of the partition lateral walls of the compartment  2  and duct: it extends along a crossing direction X of the products P for enabling the fluid communication between the compartment  2  inner volume  3  and the volume of passage  4 . As it is visible, the crossing direction X is transversal, particularly normal, to the prevalent development direction Y of the volume of passage  4 . 
         [0154]    From the geometrical point of view, the opening  7  is perimetrally delimited by an edge having a substantially rectangular or square shape. The attached figures illustrate a preferred but non limiting configuration of the invention in which the opening  7  edge exhibits at least one side, particularly the side facing the volume  4  first end  4   a,  curvilinear, particularly an arc or circle (see for example  FIGS. 3-5 ). Despite it has been shown only one configuration of the door  6  placed at the duct second end  4   b,  and exhibiting a substantially square shape, it is not excluded the possibility of forming an opening  7  in different positions of the duct (placed at the centerline of the duct or at the first end  4   a ) and/or having a shape different from the represented one, for example defining a circular, elliptical, diamond or trapezoidal shape (these configurations are not illustrated). 
         [0155]    With reference to the door  6  dimensional point of view (which is defined in an illustratively way since the sizes of the container and also of the door are completely variable because they are a function of the article to be delivered), it is possible to define a prefixed area of passage of the opening  7  which is comprised between 100 and 600 mm 2 , particularly between 300 and 400 mm 2 . It is further possible to define a minimum passage size of the opening  7  which is greater than 7 mm, particularly is comprised between 15 and 25 mm. The minimum passage size is defined by the minimum distance between two facing points of the opening  7  perimetral edge and it is advantageously greater than the transversal maximum size of the products P. 
         [0156]    As it is visible for example in  FIGS. 1, 2 and 6 , the container  1  further comprises at least one closing element  18  engaged with the volume of passage  4  and/or with the compartment  2 ; said closing element  18  is, in a non limiting way, placed at the outlet  5  outside the volume of passage  4  and outside the compartment  2 . The closing element  18  is configured for being arranged in a condition of passage in which the element  18  itself enables to deliver the products P from the outlet  5  ( FIG. 2 ); further the closing element  18  is configured for being arranged in a locking condition wherein the element  18  itself closes the outlet  5  and interdicts the products P delivery from this latter ( FIG. 1 ). In the illustrated embodiment, the closing element  18  is, in a non limiting way, constrained to the duct at an outlet  5  free edge and opposite to the recess  15 . More particularly, the closing element  18  and the duct are integrally joined and engaged by an interconnection perimetral edge  72  ( FIGS. 2 and 6 ); the closing element  18  is configured for rotating with respect to the duct around the edge  72  for switching from the condition of passage to the closing condition, and viceversa. Also in the condition wherein there is one or plural products inside the volume of passage  4 , ready to be delivered, the closing element  18 , in the locking condition, prevents the passage through the outlet  5 . More specifically, the closing element  18  comprises at least one first wall  73  engaged with the duct and exhibiting a surface extension equal to or greater than the area of passage of the outlet  5 . The first wall  73  is substantially countershaped to the outlet  5  and defines the element directly configured for interdicting the passage of products P during the locking condition of said element  18 . Further, the closing element  18  comprises a second wall  74  integrally joined to the first wall  73  and emerging transversally, particularly normal, to the first wall  73  to substantially define a “L” element. The second wall  74  is configured for facing, during the element  18  locking condition, the recess  15 . Further, the second wall  74  is configured for entering, at least partially, inside the recess  15  for stably holding the element  18  in the locking condition. Advantageously, the closing element  18  further comprises a third wall  75  emerging transversally, particularly normal, to the first and second walls  73 ,  74 ; the third wall  75  is configured for facing a duct lateral wall immediately adjacent the recess  15 ; the third wall  75  is further configured for guiding and supporting the movement of the element  18  when switches from the passage condition to the locking one, and viceversa. As it is visible in the attached figures, the walls  73 ,  74  and  75  emerge transversally to each other on approach to each other to define a housing cavity; in the passage condition of the closing element  18 , this latter is configured for receiving the products P exiting the volume of passage  4  and prevents them from dropping: the housing cavity is configured for substantially acting as an element gripping the products P exiting the volume of passage  4  ( FIG. 6 ). In a preferred but non limiting configuration of the invention, the walls  73 ,  74  and  75  are integrally joined to define a single body, particularly are integrally joined to the volume of passage  4  (duct) to define with this latter a single piece. 
         [0157]    Advantageously, also the closing element  18 , as for the compartment  2  and/or the volume of passage  4 , is made of sheet material and is obtained by folding. In a preferred but non limiting embodiment of the invention, also the closing element  18  is made of paper sheet (paper or paperboard); particularly, the paper sheet material used for making the element  18  exhibits the same characteristics as the paper/paperboard used for making the compartment  2  and/or volume of passage  4 . As hereinbefore described, in a preferred embodiment of the invention, the closing element  18  is integrally joined to the duct and/or compartment  2 ; the sheet material used for making the compartment  2  and/or duct is the same sheet used for forming the closing element  18 : in this way said closing element  18  is integrally joined to the duct and/or compartment. Advantageously the compartment  2 , volume of passage  4  and closing element  18  are made of the same paper material sheet to define a single integrally joined detail. 
         [0158]    As hereinbefore described, the container  1  can be also used for housing food products or pharmaceutical and cosmetic products. In such condition, it is advantageous to cover an inner surface of the element by a plastic material coating, for example a film. The coating has the object of defining a barrier adapted to prevent the contact of the products with the paper material; the film further defines a water and/or humidity barriers useful for avoiding the weakening and the loss of structurality with subsequent warping of the paper material forming the element  18 . Advantageously, it is possible to define an extrusion coating on one (the inner side facing the compartment  2  inner volume  3 ) or both the sides (inner and outer surfaces) of the paper material defining the closing element  18  with values which can for example vary between 10 and 50 gr/m 2  of coating material (in other words polyethylene). The coating plastic material can be for example selected among the following materials: LDPE, HDPE, PP, PE. 
         [0159]    As it is visible in the attached figures, the container  1  further comprises at least one delivery mechanism  8  engaged at least partially inside the volume of passage  4  and/or inner volume  3  of the compartment  2 , at the door  6 . The delivery mechanism  8  is configured for managing the passage of products P through the opening  7 . Specifically, the delivery mechanism  8  is configured for being placed at least in a closed condition in which the mechanism itself prevents the passage of products P through the door  6 ; the delivery mechanism  8  is further configured for being placed at least in a condition of passage in which the mechanism itself enables the passage of one or plural products P through the door  6  to enable therefore the products P to exit the compartment  2 . More particularly, the delivery mechanism  8  comprises at least one shutter  9  (see for example  FIG. 3 ) placed at the door  6  and apt to define, in cooperation with the opening  7 , a prefixed section of passage: the shutter  9 , in the closing condition, defines a section of passage apt to interdict the passage of products P while, in the passage condition, the shutter  9  defines a section of passage apt to enable the passage of the products P. quantitatively, the section of passage, defined by the cooperation between the shutter  9  and opening  7 , exhibits a surface extension comprised between 5 and 250 mm 2 , particularly between 150 and 250 mm 2 . De facto, the ratio of the area of passage defined by the opening  7  and the section of passage defined by the cooperation between the shutter  9  and opening  7 , is equal to or greater than 2, particularly is comprised between 2 and 5. 
         [0160]    In addition, the mechanism  8  comprises at least one maneuvering organ  10  (see for example  FIG. 3 ) active on the shutter  9  for commanding the closing and passage conditions of the delivery mechanism  8 ; the maneuvering organ will be better described hereinbelow. With reference to the shutter  9 , this latter comprises an elastic body configured for holding the shutter  9  itself in the closing condition: the elastic body is configured for automatically moving the shutter  9  to the closed condition from the passage condition. As it is possible to observe in the attached figures, the shutter  9  defines both the opening and obstructing element of the opening  7  and the spring-back element capable of moving the shutter  9  itself to a normally closed condition. In the embodiment illustrated in the attached figures, the shutter  9  is advantageously engaged inside the volume of passage  4  at the duct second end  4   b : the shutter  9  fully faces the opening  7 . More particularly, it is possible to observe that the shutter  9  is at least partially—particularly completely—made of sheet material and has a folded portion  11  which directly defines both the obstructing and opening body of the door  6  and the spring back body of the shutter  9  itself. 
         [0161]    As it is visible for example in  FIGS. 3-5 , the folded portion  11  comprises a first and second tabs  12 ,  13  ( FIGS. 3-5 ) facing the opening  7  and longitudinally extending away from this latter substantially parallelly to the products crossing direction X ( FIG. 3 ). De facto, the first and second tabs  12 ,  13  extend transversally, particularly normal, to the duct prevalent development direction Y, particularly from the opening  7  to a duct lateral wall opposite to said opening  7 . In other words, the first and second tabs  12 ,  13  extend between respective longitudinal edges, one of them faces the door  6  opening  7 . 
         [0162]    As it is visible in the attached figures, the first tab  12  is directly connected to the maneuvering organ  10  and faces the outlet  5 , while the second tab  13  is connected to the first tab  12 , facing a duct bottom wall  4   c,  opposite to the outlet  5 . From the geometrical point of view, the first tab  12  extends along a rectilinear direction from a first to a second end edges  12   a,    12   b;  the first end edge  12   a  of the first tab  12  is directly engaged with the maneuvering organ  10  while the second end edge  12   b  is engaged with the second tab  13 . Also the second tab  13  extends along a respective rectilinear direction from a first to a second end edges  13   a,    13   b;  the first end edge  13   a  of the second tab  13  abuts on the duct bottom wall  4   c,  while the second end edge  13   b  is engaged with the second end edge  12   b  of the first tab  12 . Substantially, the first and second tabs  12 ,  13  are engaged with each other at the respective second end edges  12   b,    13   b  ( FIG. 5 ). De facto, each tab  12 ,  13  comprises a sheet having, in a non limiting way, a rectangular or square shape. From the dimensional point of view, the first tab  12  exhibits a prefixed length comprised between 15 and 25 mm, particularly between 18 and 22; the length of the first tab  12  is defined by the maximum distance between the first and second end edges  12   a,    12   b  of the tab itself. The second tab  13  has also a prefixed length comprised between 16 and 30 mm, particularly between 20 and 26 mm; the second tab  13  length is defined by the maximum distance between the first and second end edges  13   a,    13   b  of the tab itself. Advantageously, the ratio of the second tab  13  length to the first tab  12  length is equal to or greater than 1.1, particularly is comprised between 1.15 and 1.2. 
         [0163]    As hereinbefore described, the folded portion  11  is configured for being normally arranged in a normally closed condition (shutter  9  closed condition); in such condition, the tabs  12 ,  13  are normally placed in a condition wherein they are angularly spaced from each other for defining the mechanism  8  closing condition. More particularly, in such a condition, the first end edges  12   a,    13   a  respectively of the first and second tabs  12 ,  13  are spaced from each other; in such condition, the tabs  12  and  13  define, according to section transversal to the longitudinal development direction thereof, a substantially “V” shape arranged for obstructing the passage of the products P from the opening  7 . Still more particularly, the first and second tabs  12 ,  13 , in the shutter  9  closed condition, exhibit an angular offset inside the two tabs  12 ,  13  comprised between 10° and 35°, particularly between 15° and 25°. 
         [0164]    As hereinbefore described, the folded portion  11  is configured for elastically warping for defining the condition of passage of the mechanism  8  ( FIG. 7 ); in such condition, the first and second tabs  12 ,  13  are arranged in an approached condition making them substantially to face each other ( FIG. 7 ). In such configuration, the first end edges  12   a,    13   a  of the respective tabs  12 ,  13  are close to each other, particularly are at least partially in contact. 
         [0165]    It is observed that thanks to the folded portion  11  structure, in cooperation with the door  6 , it is possible to define, in the delivery mechanism  8  closing condition, a housing seat  14  configured for holding only one product P ( FIG. 5 ); the housing seat  14  is configured for substantially defining a dosing chamber which, in the delivery mechanism  8  passage condition, enables at least to deliver the product P held in the housing seat  14 . More particularly, the first tab  12  (specifically the longitudinal edge facing the door  6 ), in the delivery mechanism  8  closing condition, in cooperation with the opening  7  perimetral edge, defines said housing seat  14 . The first tab  12 , during the switching from the passage condition to the closed one, is configured for approaching the second tab  13  for defining said passage condition and enabling to deliver the product P placed in the housing seat  14  ( FIG. 7 ). 
         [0166]    In a preferred but non limiting embodiment of the invention, the folded portion  11 , and particularly the first and second tabs  12 ,  13 , is made of paper sheet material (paper or paperboard) and is obtained by folding; particularly, the paper sheet material used for making the portion  11  exhibits the same characteristics as the paper sheet material used for making the compartment  2  and/or the duct. In a preferred embodiment of the invention, also the folded portion  11  is integrally joined to the compartment  2  and/or with the duct; in such configuration, the sheet material used for making said portion  11  is the same used for forming the duct and/or compartment for defining only one integrally joined detail. 
         [0167]    The paper sheet material used for the portion  11  can exhibit a grammage comprised between 150 and 400 gr/m 2 , particularly comprised between 200 and 300 gr/m 2 . As hereinbefore described, the container  1  can also be used for housing food products or pharmaceutical and cosmetic products. In such condition, it is advantageous to cover at least part of the portion  11  with a plastic material coating, for example a film. The coating has the object of defining a barrier adapted to prevent the contact of the products with the paper material; the film further defines a water and/or humidity barriers useful for avoiding the weakening and the loss of structurality of the portion  11 , and also the elastic characteristics useful for enabling the automatic spring back of the folded portion itself Advantageously, it is possible to define an extrusion coating on one or both the paper material sides defining the folded portion  11  with values which can for example vary from 10 to 50 gr/m 2  of the coating material (in other words polyethylene). The coating plastic material can be for example selected among the following materials: LDPE, HDPE, PP, PE. 
         [0168]    Instead, with reference to the maneuvering organ  10 , this latter is engaged inside the duct and extends from a first end  10   a,  located at the outlet  5 , to a second end  10   b  connected to the first tab  12  and placed at the opening  7 . The maneuvering organ  10  is configured for receiving, at the first end  10   a,  a thrust S ( FIG. 6 ) directed along the duct prevalent development direction Y; due to the thrust S, the maneuvering organ  10  is configured for sliding inside the duct along the prevalent development direction Y of the same to exert a thrust on the first tab  12 . Following the sliding, the maneuvering organ  10  is configured for elastically warping the folded portion  11  for enabling to angularly approach the tabs  12 ,  13  and defining the delivery mechanism  8  passage condition. 
         [0169]    More specifically, the maneuvering organ  10  exhibits a prevalent development direction which, in the engagement condition between the organ  10  and volume of passage, is substantially parallel to the duct development direction Y. As it is for example visible in  FIG. 4 , the maneuvering organ  10  second end  10   b  is directly connected to the first end edge  12   a  of the first tab  12 ; the maneuvering organ  10  thrust S therefore forcedly act on the thirst end edge  12   a  of the first tab  12 , which, following such action, substantially rotates around the second end edge  12   b  of the same (therefore around the second end edge  13   b  of the second tab  13 ) for approaching the tab  13 . 
         [0170]    As it is visible in  FIGS. 2 and 6 , the maneuvering organ  10  extends to the duct first end  4   a;  advantageously, the maneuvering organ  10  first end  10   a  exhibits at least one thrust portion placed on the same side of the recess  15 , and longitudinally projects with respect to this latter ( FIG. 2 ). De facto, the maneuvering organ  10  first end  10   a  is configured for facing the recess  15  in the mechanism closed condition; in such condition, the maneuvering organ  10  can be reached from the outside and is displaceable along the duct development direction Y: the organ  10  movement enables to activate the shutter  9  for bringing it in the passage condition. De facto, the recess  15  is configured for enabling to activate the maneuvering organ  10  by the thrust on the same at the first end  10   a;  the defined depth of the recess  15  is such to enable to correctly warp the folded portion  11  and therefore the passage of one or plural products P from the opening  7  ( FIGS. 6 and 7 ). 
         [0171]    In a preferred but non limiting embodiment of the invention, the maneuvering organ  10  is also made of sheet material and exhibits, again in a non limiting way, a rectangular shape: a sheet end edge is engaged with the tab  12  first end edge  12   a.  Advantageously, the sheet abuts on and is guided on the lateral wall of the duct carrying the recess  15  as clearly illustrated in  FIGS. 2 and 6 . Advantageously, the delivery mechanism  8  is a single piece; in such condition, the maneuvering organ  10  is integrally joined to the shutter  9  to define a single detail. 
         [0172]    In a preferred but non limiting embodiment of the invention, the maneuvering organ  10  is made of paper sheet material (paper or paperboard); particularly, the paper sheet material used for making the maneuvering organ  10  exhibits the same characteristics as the paper sheet material used for making the shutter  9 . As hereinbefore described, in a preferred embodiment of the invention, the maneuvering organ  10  is integrally joined to the shutter  9 ; in such configuration, the sheet material used for making said organ  10  is the same as the one used for forming the shutter  9  for defining a single integrally joined detail. 
         [0173]    However, it is possible to obtain at least two preferred configurations of the invention. In a first configuration, the maneuvering organ  10  and shutter  9  are integrally joined to but distinct from the other container  1  components (compartment  2 , volume of passage  4  and closing element  18 ). In a second configuration, all the container details (shutter  9 , maneuvering organ  10 , compartment  2 , volume of passage  4  and closing element  18 ) are integrally joined to define a container  1  made from a single sheet, particularly a single sheet of paper material. 
         [0174]    The paper sheet material used for the maneuvering organ  10  can exhibit a grammage comprised between 150 and 400 gr/m 2 , particularly comprised between 200 and 300 gr/m 2 . As hereinbefore described, the container  1  can also be used for housing food products or pharmaceutical and cosmetic products. In such condition, it is advantageous to cover at least part of the maneuvering organ  10  with a plastic material coating, for example a film. The coating has the object of defining a barrier adapted to prevent the contact of the products with the paper material; the film further defines a water and/or humidity barriers useful for avoiding the weakening and the loss of structurality of the maneuvering organ  10 , which can impair the thrusting capacity of this latter. Advantageously, it is possible to define an extrusion coating on one or both the sides of the paper material defining the maneuvering organ  10  with values which can for example vary from 10 to 50 gr/m 2  of the coating material (in other words polyethylene). The coating plastic material can be for example selected among the following materials: LDPE, HDPE, PP, PE. 
       Process for Making the Container 
       [0175]    Further, it is an object of the present invention a process for making the container  1  as hereinbefore described. The process comprises at least one step of preparing the compartment  2  which provides to prepare at least one flat sheet and folding the same to define the inner volume  3 ; as hereinbefore described, the compartment  2  is advantageously made of paper material, therefore, the raw flat sheet can comprise a blank made of paper and/or paperboard. 
         [0176]    Further, the process provides to prepare the volume of passage  4 , which provides to prepare at least one flat sheet  52  ( FIGS. 8 and 9 ) comprising at least one first, second and third portions  52   a,    52   b,    52   c  each exhibiting a substantially rectangular shape. The first and second portions  52   a  and  52   b  are integrally joined to an interconnection longitudinal edge  55  while the second and third portions  52   b,    52   c  are integrally joined to a respective interconnection longitudinal edge  56 ; the interconnection edge  55  of the first and second portions  52   a,    52   b  is opposite to the interconnection longitudinal edge  56  of the second and third portions  52   b,    52   c  with respect to the second portion itself. Advantageously, the second sheet  52  further comprises a fourth portion  52   d  connected to the third portion  52   c  at a respective interconnection longitudinal edge  60 : the third portion  52   c  is interposed between the second and fourth portions  52   b  and  52   d  of the sheet  52 . As it is visible in the attached figures, the third portion  52   c  of the second sheet  52  comprises an opening  58  which is configured for defining the opening  7  of the volume of passage  4  of the container  1 . The opening  58  is delimited at a free edge  59  defining a substantially “U” shape whose concavity faces away from the third portion  52   c  itself. 
         [0177]    Then, the sheet  52  preparing step comprises at least one step of folding the same to define the duct  4 . More particularly, the folding step provides the following sub-steps:
       folding, at the interconnection longitudinal edge  55 , the first and second portions  52   a,    52   b  so that these latter define, according to a cross section, a substantially “L” shape,   folding, at the edge  56 , the second and third portions  52   b,    52   c  so that these latter define, according to a cross section, a substantially “L” shape, the first, second and third portions  52   a ,  52   b,    52   c  defining, according to a cross section, a substantially “U” shape.       
 
         [0180]    In case the sheet  52  exhibits the fourth portion  52   d,  the process further exhibits at least one sub-step of folding, at the interconnection longitudinal edge  60 , the third and fourth portions  52   c,    52   d  so that these latter define, according to a cross section, a substantially “L” shape whose concavity is opposite to the volume of passage  4 . 
         [0181]    As hereinbefore described, the volume of passage  4  and compartment  2  can be made in a single piece; in such condition, such elements are made of a single die-cut flat sheet defining a single blank  50 . Particularly, such blank  50  can comprise the sheet  52  connected to two further sheets  53  and  54  ( FIGS. 8 and 9 ). The sheet  53  comprises a main flat body  57  exhibiting a substantially rectangular shape delimited by a lower edge  53   a,  a first and second lateral edges  53   a,    53   b,  and an upper edge  53   d.  As it is visible in  FIGS. 8 and 9 , the first lateral edge  53   b  is connected, particularly integrally joined, with the sheet  52 , particularly with the first sheet  52  portion  52   a.  At the upper edge  53   d,  particularly at the joining angle between the first edge  53   b  and the upper edge  53   d  of the sheet  53 , this latter exhibit a through opening  62  obtained by a step of cutting the sheet  53  itself. The opening  62  is configured for defining the container  1  recess  15 . The sheet  54  comprises at least one main body  54   a  and a connecting portion  54   b  both exhibiting a substantially rectangular shape: said portions  54   a,    54   b  exhibit an interconnection longitudinal edge  61  ( FIG. 8 ). In order to make the compartment  2  and volume of passage  4  in a single piece, the process, following or simultaneously with the step of folding the sheet  52 , provides to prepare the first, second and third portions  52   a,    52   b,    52   c  folded on the sheet  53  main body  57  in order to define the duct of the volume of passage  4 . 
         [0182]    Then, the process further provides to fold the main body  54   a  and connecting portions  54   b  of the sheet  54  at the interconnection longitudinal edge  61  to define, according to a cross section, a substantially “L” shape. Then, it is possible to position the sheet  54  on the sheet  52  in order to define both the compartment  2  and duct. It is useful to note that the sheet  52  comprises at least one connecting portion  63  integrally joined to the first portion  52   a  and emerging longitudinally from this latter. The sheet  54  instead comprises a lower abutment portion  64  integrally joined to a main body  54   a  lower edge  54   c  and longitudinally emerging from this latter; the sheet  54  further comprises also two connecting portions  63  integrally joined respectively with an upper and lower edges of the sheet  54  connecting portion  54   b  and longitudinally emerging from these latter. Further, it is observed that the sheet  54  comprises at least one upper abutment portion  65  integrally joined to an upper edge  54   b  of the main body  54  and longitudinally emerging from this latter. 
         [0183]    Further the process provides, for defining the compartment  2  and duct, at least the following sub-steps:
       folding the lower abutment portion  64  towards the sheet  54  main body  54   a ,   following positioning the sheet  54  on the sheet  52 , engaging the sheet  54  connecting portion  63  with the abutment portion  64  of the same for holding the abutment portion  64  in the folded configuration,   following positioning the sheet  54  on the sheet  52 , engaging the sheet  52  connecting portion  63  with the sheet  54  lower abutment portion  64  for granting the engagement of the second and fourth sheets  52 ,  54 ,   folding the upper abutment portion  65  towards the sheet  54  main body  54   a ,   following positioning the sheet  54  on the sheet  52 , engaging the sheet  54  connecting portion  63  with the upper abutment portion  65  of the same for holding the abutment portion itself in the folded configuration.       
 
         [0189]    De facto, the sheet  54  abutment portions  64  and  65  are configured for defining the container  1  upper and lower walls, and also the duct bottom wall  4   c  for abutting on the second tab  13 . The connecting portions  63  are configured for granting to hold the container  1  in its folded (three-dimensional) configuration. 
         [0190]    Further, it is observed that the sheet  54  comprises locking portions  76  emerging from the abutment portions  64  and  65 ; such portions are configured for being folded after having positioned the sheets  52  and  54  in order to constrain them to the sheet  53  main body  57 . Such portions can be folded and glued to the sheet  53  main body  57  in order to hold the container  1  in its three-dimensional configuration, for example. 
         [0191]    As hereinbefore described, both the compartment and volume of passage are advantageously made of paper material, therefore, the flat raw sheets  52 ,  53  and  54  comprise a single blank  57  of paper and/or of paperboard. 
         [0192]    As hereinbefore described, further the container  1  can comprise at least one closing element  18 . The process provides to prepare at least one flat sheet and folding the same to define the element  18 ; as hereinbefore described, said element  18  is advantageously made of a paper material, therefore, the raw flat sheet can comprise a paper and/or paperboard blank. Advantageously, the sheet defining the element  18  is integrally joined to the sheet  54  ( FIG. 8 ); particularly, the sheet  54  comprises, at an upper edge  54   d,  a closing portion  66  comprising at least one first and at least one second portions  67 ,  68  integrally joined by means of an interconnection longitudinal edge  69 . The closing portion  66  being adapted to define at least part of the upper abutment portion  65  and is integrally joined to this latter by means of a tear longitudinal edge  70 . The process further comprises at least the following sub-steps:
       folding, at the sheet  54  upper edge  54   d,  the closing portion  66  towards the lower abutment portion  64 ,   folding, substantially at an intermediate tracing  71 , the first and second portions  67 ,  68  towards the first lower abutment portion  64 , the first and second folded portions  67 ,  68  define, according to a cross section, a substantially “L” shape; the first portion is configured for contacting the sheet  53  main body  57  while the second portion  68  is configured for contacting the sheet  52  first portion  52   a,      folding the second portion  68  towards the first portion  67 ,   stably engaging said first and second folded portions for defining said closing element  18 .       
 
         [0197]    Further, the process provides to step of preparing the delivery mechanism  8 , during which the shutter  9  and maneuvering organ  10  are formed; as hereinbefore described, the shutter  9  is configured for defining both the section of passage of the container  1  and the spring-back element adapted to automatically restore the shutter itself to the closing condition. The step of preparing the shutter  9  comprises at least the following steps:
       preparing a sheet  51 ,   folding said sheet  51  to form the folded portion  11 ,   positioning said folded portion  11  at the door  6 .       
 
         [0201]    As hereinbefore described, the folded portion  11  is configured for defining both the door  6  obstruction element and directly the shutter  9  spring-back element. The folded portion  11  forming step comprises at least a step of placing said portion  11  at the door  6  so that said portion  11  can cooperate with the opening  7  for defining the housing seat  14  configured for holding only one product P. 
         [0202]    The step of preparing the delivery mechanism  8  comprises at least the step of preparing the maneuvering organ  10  also made of sheet material. 
         [0203]    Advantageously, the shutter  9  and the maneuvering organ  10  are both made of the sheet  51 , particularly of paper sheet material; as it is visible in  FIGS. 8 and 9 , the sheet  51  comprises at least one main portion  51   a  and a connecting portion  51   b.  The step of preparing the delivery mechanism  8  provides to fold the connecting portion  51   b  to define said first and second tabs  12 ,  13  while the main body  51   a  defines the whole maneuvering organ  10 . The delivery mechanism  8  of sheet material can be placed inside the compartment  2  and duct before folding and forming these latter; particularly, the mechanism  8  can be abutted on the main body  57  and then the sheets  52 ,  53  and  54  can be folded for receiving the shutter  9  and organ  10 . Advantageously, the flat sheet  51  used for defining the delivery mechanism  8  can be integrally joined to the sheet  53 ; particularly, in a preferred embodiment, the connecting portion  51   b  is integrally joined, on one side, with the sheet  51  main body  51   a  and, on the other side, with the sheet  53  lower edge  53   a  ( FIG. 8 ). 
         [0204]    In a preferred embodiment of the invention, the container  1  is obtained from a single blank  50  comprising the sheets  51 ,  52 ,  53  and  54  defined also as first, second, third and fourth sheets. In such condition, the process provides to cut a single flat sheet to define a single blank  50  as illustrated in  FIG. 8 . The first step of the process provides to fold the first sheet  51  connecting portion  51   b  and place the main body  51   a  of the same on the third sheet  53  main body  57 . The connecting portion is folded to define the portion  11  which exhibits, according to a cross section, a “V” shape whose concavity faces the third sheet  53  main body  47 . Then, the second sheet  52  is folded and is placed on the third sheet  53  so that the second sheet  52  duct houses the shutter  9  folded portion  11 ; de facto the folded portion  11  is interposed between the second portion  52   b  of the second sheet  52  and the third sheet  53  main body  57 , while the fourth portion  52   d  of the second sheet  52  abuts at least on part of the maneuvering organ  10 . Following positioning the first and second sheets  51 ,  52  on the third sheet  53 , the process provides to place and then fix the fourth sheet  54  on the second sheet  52 : the second, third and fourth sheets  52 ,  53 ,  54  define the compartment  2 , the volume of passage and also the container  1  lateral walls. In  FIG. 9  it is possible to observe with a detailed and exploded view the structure of the first, second, third and fourth sheets  51 ,  52 ,  53 ,  54 . Instead, Figures from  10  to  13  schematically show the blank  50  folding steps adapted to define a semi-finished product folded in a compact form and ready for being arranged in the three-dimensional configuration illustrated in  FIGS. 1 and 2 , for example.  FIG. 10  illustrates a first step of folding the whole first sheet  51  on the third sheet  53 .  FIG. 10  schematically shows a second step of folding at least part of the second sheet  52  on the first sheet  51 . Particularly, the second, third and fourth portions  52   b,    52   c  and  52   d  of the second sheet are all folded on the first sheet  51  around the interconnection longitudinal edge  55  of the second sheet  52 . Then, the third sheet  53  with the first and second sheets  51 ,  53  are folded on the fourth sheet  54  around the second lateral edge  53   c  of the third sheet  53 . The folded blank  50  is easily configurable in its three-dimensional shape in which it is possible to proceed with locking the same by fixing the different connection and locking portions  63  and  76  of the second and fourth sheets  52 ,  54 .
