Description

[Technical field]

[0001] The present invention relates to an opening device for packages, in particular for pourable products, and more particularly for packages having a body filled with a pourable food product.

[0002] Additionally, the present invention relates to a pourable product, and more particularly to a package having a body filled with a pourable food product and an opening device coupled to the body. [Background technology]

[0003] As is well known, many liquid or pourable food products, such as fruit juices, milk, dairy drinks, drinkable yoghurt, wine, tomato sauce, salt, sugar, etc., are sold in packages, in particular sealed packages, made from sterilised packaging material.

[0004] A typical example is the parallelepiped package for pourable food products known as Tetra Brik Aseptic®, which is made by sealing and folding a laminated strip of packaging material. The packaging material has a multi-layer structure including a base layer of carton and / or paper, covered on both sides with a layer of heat-sealable plastic material, e.g., polyethylene. In the case of aseptic packages for shelf-stable products, the packaging material includes a layer of oxygen barrier material, e.g., aluminum foil, which overlaps with a layer of heat-sealable plastic material and is covered with another layer of heat-sealable plastic material to form the inner surface of the package that ultimately contacts the food product.

[0005] These types of packages include a body formed from a multi-layer packaging material and a pre-defined spout that allows for pouring of the pourable product from the package. The package further includes an opening device coupled to the body and disposed about the pre-defined spout. The opening device is designed to seal the package prior to initial opening of the opening device and allow for controlled pouring.

[0006] A typical opening device includes a collar having an inner surface defining a flow path and having a dispensing outlet, and a closure group configured to selectively open and close the dispensing outlet.

[0007] Some closure groups also include a closure and a sealing lip that extends from the closure into the flow passage when the closure covers the spout and contacts an inner surface to seal the flow passage against leakage of the pourable product from the flow passage.

[0008] Although known opening devices function satisfactorily, there is a need in the art for improvements to known opening devices, particularly to improve the sealing effect provided by the bond between the collar and the sealing lip. Summary of the Invention [Problem to be solved by the invention]

[0009] It is therefore an object of the present invention to provide an improved opening device for packages, in particular packages having a body formed from a multi-layer packaging material and filled with a pourable product, in particular a pourable food product, which is simple and low-cost.

[0010] In particular, it is an object of the present invention to provide an improved opening device for packages, in particular packages having a body formed from a multi-layer packaging material and filled with a pourable product, in particular a pourable food product, which is provided with improved sealing properties, in a simple and cost-effective manner.

[0011] A further object of the present invention is to provide a package, in particular a package having a body formed from a multi-layer packaging material and filled with a pourable product, in particular a pourable food product, which package has an opening device, in particular an opening device with improved sealing properties, in a simple and low-cost manner.

[0017] Number 1 indicates the package as a whole (only a portion of which is shown to the extent necessary for the understanding of the invention); - a body 2, in particular made from a multi-layer packaging material, which is filled and / or can be filled with a pourable product, in particular a pourable food product, and which has a given pouring outlet (not shown, but known per se) configured in particular to allow the pouring of the pourable product from the body 2; an opening device 3, in particular made from a polymeric material, connected to the body 2 around the predetermined outlet and controllably configured to seal the predetermined outlet and to open the predetermined outlet to allow the pouring of the pourable product; Equipped with.

[0018] Its products include milk, tomato sauce, dairy drinks, yogurt drinks, water, sugar, salt, juice and milky lotion.

[0019] According to some preferred non-limiting embodiments, the packaging material may consist of at least one layer of fibrous material, e.g. a paper or cardboard layer, and at least two layers of heat-sealable plastic material, e.g. a polyethylene layer, sandwiching the layers of fibrous material between each other. One of the two layers of heat-sealable plastic material may define the inner surface of the body 2 that contacts the cast product.

[0020] Preferably, the packaging material may also comprise a layer of gas- and light-barrier material, such as an aluminum foil or an ethylene vinyl alcohol (EVOH) film, in particular arranged between one of the layers of heat-sealable plastic material and the layer of fibrous material. Preferably, but not necessarily, the packaging material may also comprise a further layer of heat-sealable plastic material, interposed between the layer of gas- and light-barrier material and the layer of fibrous material.

[0021] Preferably, each package 1, in particular each body 2, may be obtained from a respective blank of a multi-layer packaging material. In particular, the blank may define a precursor of each package 1, in particular each body 2.

[0022] More specifically, each blank may include a respective designated pouring outlet, which may in particular be covered by a separator membrane, which may be formed from a gas barrier material, in particular the separator membrane may be defined by a portion of a layer of gas barrier material and light barrier material and / or a layer of heat sealable plastic material.

[0023] According to some preferred non-limiting embodiments, the multi-layer packaging material may be provided in the form of a web, whereby the blanks may be successively placed relative to one another. During the formation of the package 1, the web may be formed into a tube, sealed longitudinally, filled with the cast product, sealed transversely, and cut to correspond to the extensions of the blanks.

[0024] According to preferred, non-limiting embodiments, each opening device 3 may be applied, in particular molded or glued, to the respective body 2 or to the respective packaging blank. Preferably, each opening device 3 may be molded on the respective packaging blank for a designated spout. In particular, as will be further explained below, a first part of the opening device 3 may be molded on the respective packaging blank and a second part of the opening device 3 may be applied on the first part after molding of the first part.

[0025] In particular, the opening device 3 may be molded by a respective mould.

[0026] 1 and 2, the body 2 may extend longitudinally, along a first transverse axis B perpendicular to the longitudinal axis A, and along a second transverse axis C perpendicular to the first transverse axis B and the longitudinal axis A. In particular, the extension of the package 2 along the longitudinal axis A may be greater than the extension of the package 2 along the first transverse axis B and the second transverse axis C.

[0027] Preferably, the body 2 may be of parallelepiped shape.

[0028] According to some preferred, non-limiting embodiments, the body 2 may comprise a first wall (not shown, known as such), in particular transverse and more in particular perpendicular to the longitudinal axis A, from which the body 2 may extend along the longitudinal axis A. Preferably, the first wall may define a support surface of the package 1, in particular the body 2, which may be designed to come into contact with a support, such as for example a shelf, when exposed in use, for example in a point of sale, or when stored. In particular, when placed on a support, the first wall may define a bottom wall.

[0029] Preferably, the body 2 may also comprise a side wall 4 which is (fixedly) connected to the first wall and extends from the first wall along, in particular substantially parallel to, the longitudinal axis A.

[0030] Preferably, the body 2 may comprise a second wall 5 opposite the first wall and (fixedly) connected to the side wall 4. In particular, the side wall 4 may be interposed between the first wall and the second wall 5.

[0031] In particular, when the package 1 is placed on a support, the second wall 5 may define a top wall.

[0032] According to the illustrated non-limiting embodiment, the first wall and the second wall 5 may be parallel to each other.

[0033] According to alternative non-limiting embodiments not shown, the first wall and the second wall 5 may be inclined relative to one another. In particular, the second wall 5 may define a sloped top or may define part of a gable top.

[0034] According to some non-limiting embodiments, the second wall 5 may include and / or comprise a designated spout.

[0035] According to some preferred non-limiting embodiments, the package 1, and in particular the body 2, may include an interior space configured to accommodate and / or contain a pourable product. In particular, the first wall, the side wall 4 and the second wall 5 may define the interior space.

[0036] With particular reference to Figures 1 to 5b, the opening device 3 is configured as follows: - a collar 9 having a dispensing outlet 11 and defining a flow path 10 of a pourable product; and a closure group 12 coupled to the collar 9 and configured to selectively open and close the spout 11;

[0037] Furthermore, the opening device 3 may also comprise a base frame 13 configured to couple and / or connect the opening device 3 to the body 2, in particular to the second wall 5, about a designated spout.

[0038] In particular, the collar 9 may extend from the base frame 13.

[0039] Preferably, the collar 9 and the base frame 13 may be integrally connected to each other. More preferably, the collar 9 and the base frame 13 may be made as one piece.

[0040] Furthermore, the closure group 12 may be manufactured as a separate part. In particular, the closure group 12 may be joined to the collar 9 after the collar 9 has been formed.

[0041] More specifically, the collar 9 may comprise an inlet 14 configured to allow the introduction of a pourable product into the flow channel 10. In particular, the inlet 14 may be located opposite the pouring outlet 11.

[0042] More specifically, the collar 9 may extend centrally. In particular, the outlet 11 and the inlet 14 may be arranged at respective axial ends of the collar 9.

[0043] Additionally, the collar 9 includes an inner surface 15 that defines the flow passage 10 .

[0044] Additionally, the collar 9 may have an outer surface 16 opposite the inner surface 15 .

[0045] With particular reference to Figures 1, 3, 4 and 5, the closure group 12 includes a closure 17 configured to selectively open and close the spout 11.

[0046] Closure 17 is a closed position, in which the closure 17 closes and / or covers the outlet 11, in particular for preventing the outflow of pourable product from the outlet 11; and an open position in which the closure 17 is removed from the outlet 11, in particular for allowing the pourable product to flow out of the outlet 11; may be movable between

[0047] In other words, the closure 17 may be configured to selectively open and close the spout 11 when in the open and closed positions, respectively.

[0048] Preferably, the closure 17 may be reversibly movable between a closed position and an open position.

[0049] The closure group 12 also comprises a sealing lip 18 extending from the closure 17, in particular an annular sealing lip 18. In particular, the sealing lip 18 may be integrally connected to the closure 17.

[0050] More specifically, the sealing lip 18 may extend into the flow passage 10 when the closure 17 is in the closed position.

[0051] Advantageously, and with particular reference to Figures 4, 5a and 5b, the opening device 3 also comprises one or more annular protruding elements 19, in the particular case three are shown, extending from the inner surface 15 into the flow passage 10. Preferably, each of the one or more annular protruding elements 19 may be integral with the inner surface 15.

[0052] The sealing lip 18 interacts, in particular contacts, with at least one of the one or more annular projecting elements 19 in order to cooperate with the annular projecting element 19 to seal the spout 11 when the closure 17 is in the closed position. In particular, the interaction between the sealing lip 18 and the annular projecting element 19 determines the airtightness of the opening device 3 when the closure 17 is in the closed position.

[0053] More specifically, sealing the spout 11 while the closure 17 is disposed in the closed position ensures that pourable product does not leak out of the flow path 10 while the closure 17 is in the closed position.

[0054] More precisely, the overall sealing of the spout 11 results from both the interaction of the sealing lip 18 with at least one of the one or more annular projecting elements 19 and from the presence of the closure 17 .

[0055] 1, 3 and 5a, the closure 17 comprises a main wall 25 and a lateral annular wall 26 integrally connected to and projecting laterally from the main wall 25. In particular, when the closure 17 is arranged in the closed position, the main wall 25 covers the spout 11 (in other words, the main wall 25 overlaps the spout 11), and the lateral annular wall 26 at least partially surrounds the collar 9 and in particular faces the outer surface 16.

[0056] Preferably, the sealing lip 18 is integrally connected to and extends from the main wall 25 , and in particular the inner surface 27 of the main wall 25 .

[0057] In particular, the inner surface 27 may face the flow passage 10 when the closure 17 is in the closed position.

[0058] According to some preferred, non-limiting embodiments, the opening device 3 may comprise at least two, preferentially at least three, annular protruding elements 19. Depending on the actual position of the sealing lip 18 in the flow passage 10 when the closure 17 is in the closed position, it may happen that the sealing lip 18 contacts only one of the annular protruding elements 19 (which is still sufficient to improve the tightness of the opening device 3 when the closure 17 is in the closed position). Examples of such situations are also depicted, for example, in Figures 4 and 5a.

[0059] It should be noted that the actual position of the sealing lip 18 may vary between successive placements of the closure 17 in the closed position. Thus, there may be positions of the sealing lip 18 where the sealing lip 18 contacts only one of the annular projecting elements 19, but there may also be positions of the sealing lip 18 where the sealing lip 18 contacts two or more annular projecting elements 19.

[0060] In particular, having two or more annular projection elements 19 ensures that the sealing lip 18 interacts with at least one of the annular projection elements 19 to obtain a sealing effect independent of its actual position.

[0061] Preferably, the annular projecting elements 19 may be axially offset from one another (relative to the central axis E).

[0062] Preferably, each annular projection element 19 may include a tip portion 28 .

[0063] According to some possible embodiments, each annular projecting element 19 may have a respective radial extension.

[0064] Possibly, the radial extensions of each of the annular protruding elements 19 may be different from each other, or at least two may have the same radial extension, or at least one annular protruding element 19 may have a radial extension that is different from the radial extensions of the other annular protruding elements 19.

[0065] Additionally, the radial extension of each annular projection element 19 into the flow passage 10 may be such that each tip portion 28 lies on and / or contacts an imaginary cylindrical surface (of an imaginary cylinder disposed within the flow passage 10). In other words, when considering a cross-section of the annular projection element 19 relative to a cross-sectional plane having the central axis E, each point originating from the tip portion 28 lies on a straight line.

[0066] Preferably, at least one annular protruding element 19 may be arranged adjacent to the spout 11 .

[0067] More precisely, the at least one annular projecting element 19 may be adjacent to a rim 29 of the collar 9 (the rim 29 delimiting the spout 11 ) and axially offset with respect to the central axis E.

[0068] According to some preferred non-limiting embodiments, the one or more annular protruding elements 19 can protrude into a first zone 30 of the flow channel 10. In particular, the first zone 30 can extend from the spout 11 towards the inlet opening 14.

[0069] Additionally, the flow path 10 may include a second zone 31 that is separate from the first zone 30 and extends toward the inlet opening 14. In particular, the second zone 31 may extend from the first zone 30 to the inlet opening 14.

[0070] Preferentially, the extension of the first zone 30 may correspond to a maximum of one third of the extension of the flow passage 10 from the outlet 11 to the inlet 14. In other words, the extension of the second zone 31 may correspond to at least two thirds of the extension of the flow passage 10 from the outlet 11 to the inlet 14. It is thus possible to keep the extension of the sealing lip 18 within certain limits.

[0071] More specifically, the one or more annular projection elements 19 may be arranged coaxially with respect to the central axis E.

[0072] Preferably, the sealing lip 18 may have an outer diameter equal or substantially equal to the inner diameter of the collar 9. Alternatively, the outer diameter may be equal or substantially equal to an inner diameter defined by one or more annular protruding elements 19. In this way, it is ensured that the sealing lip 18 enters the flow passage 10 and interacts with at least one of the annular protruding elements 19, particularly independently of the actual position of the sealing lip 18 within the flow passage 10.

[0073] With particular reference to FIGS. 3, 4 and 5 a , the sealing lip 18 may include at least one curved portion, and in particular at least one curved end portion 32 .

[0074] Furthermore, the sealing lip 18 may comprise a connection portion 33 connected, in particular integrally connected, to the closure 17 , in particular to the main wall 25 and more particularly to the inner side 27 .

[0075] Preferably, at least one curved portion, in particular the curved end portion 32 , may be connected to a connection portion 33 .

[0076] Returning to Figures 2, 3 and 4, the opening device 3 may comprise a closure element 37 which is disposed within the flow path 10 and / or which is disposable within the flow path 10 and configured to close the flow path 10 when disposed within the flow path 10, i.e. the closure element 37 may be disposed within the flow path 10 so as to block fluid communication between the inlet opening 14 and the outlet 11.

[0077] In particular, the closure element 37 may be disposed within the flow passage 10 .

[0078] Preferably, the closure element 37 may be arranged coaxially relative to the collar 9 .

[0079] Preferably, the base frame 13, the collar 9 and the closure element 37 may be made in one piece.

[0080] In particular, the closure element 37 may be rupturably fixed to the collar 9, in particular to the inner surface 15. More particularly, during the initial movement of the closure element 37 away from the collar 9 and / or out of the flow passage 10, the closure element 37 irreversibly ruptures, i.e. the closure element 37 may come into contact with the collar 9, in particular to the inner surface 15, again when newly positioned in the flow passage 10, but is not re-fixed to the collar 9, in particular to the inner surface 15.

[0081] More specifically, the closure element 37 comprises: a membrane wall 38 breakably fixed to the collar 9, in particular to the inner surface 15; - a coupling structure 39 extending from the membrane wall 38 and operatively coupling the closure element 37 to the closure group 12, in particular to the closure 17; The present invention may also include:

[0082] In particular, the coupling structure 39 may be integral with the membrane wall 38 or may extend from the membrane wall 38 .

[0083] More specifically, the membrane wall 38 may be configured to rupturably peel away from the collar 9, particularly the inner surface 15, to allow fluid communication between the inlet 14 and the outlet 11 and to allow for the dispensing of the pourable product.

[0084] More specifically, the membrane wall 38 may be controllable between an active position in which the membrane wall 38 is positioned within the flow path 10 to block fluid communication between the outlet 11 and the inlet 14, and an inactive position in which the membrane wall 38 is positioned out of the flow path 10 to allow fluid communication between the outlet 11 and the inlet 14.

[0085] In particular, a connecting structure 39 connects the closure element 37, particularly the main wall 25, to the closure 17 so that the membrane wall 38 is in an actuated position and an inactuated position when the closure 17 is in the closed position and the open position, respectively.

[0086] More specifically, the connecting structure 39 may be welded and / or glued and / or fused to the closure group 12 , in particular to the closure 17 , and more particularly to the inner surface 27 .

[0087] According to some preferred non-limiting embodiments, the closure group 12 may include a coupling ring 40 disposed around the collar 9 .

[0088] In particular, the closure 17 is coupled to a coupling ring 40, which may in particular be secured by a tether, and more in particular be secured by a hinge.

[0089] Preferably, the closure 17 is hinged to the coupling ring 40 and may be angularly movable about a hinge axis between a closed position and an open position.

[0090] Preferably, the closure group 12 may also include one or more breakable coupling bridges breakably connected to the coupling ring 40 and to the closure 17, in particular to the side wall 26, and configured to irreversibly break during a first movement of the closure 17 from the closed position to the open position.

[0091] According to some non-limiting embodiments, the base frame 13, the collar 9, the annular protruding element 19 and the closure element 37 may in particular be integrally formed. In particular, the base frame 13, the collar 9 and the closure element 37 may be formed during the molding process, in particular during the molding of the opening device 3 onto the respective packaging blank.

[0092] Furthermore, the closure group 12 may be coupled to the collar 9 after the base frame 13, collar 9 and closure element 37 are formed.

[0093] In other words, the base frame 13, collar 9, annular protruding element 19 and closure element 37 may define a first portion of the opening device 3, and the closure group 12 may define a second portion of the opening device 3. Thus, the closure group 12 is applied to the collar 9 for a particular designated spout after molding of the base frame 13, collar 9, annular protruding element 19 and closure element 37.

[0094] In particular, the shaping of the first part into a blank defining the body 2 or a precursor of the body 2 relies on the use of a respective mould.

[0095] In use, the user receives the package 1 with the closure 17 in the closed position. Furthermore, the membrane wall 38 is in the open position and is still rupturably connected to the collar 9.

[0096] To access the pourable product, the user must control the closure 17 from a closed position to an open position, in particular moving the membrane wall 38 from an open position to a non-open position, causing the membrane wall 38 to burst from the collar 9. This allows the pourable product to flow from the interior space through the flow passage 10 via the spout 11.

[0097] The closure 17 can then be repeatedly moved between the open and closed positions, each time the closure 17 is moved to the closed position, the sealing lip 18 sealing the flow passage 10 by interacting, in particular contacting, with at least one of the annular protruding elements 19.

[0098] In particular, the sealing lip 18 contacts at least one annular projection element 19 in any angular position.

[0099] The advantages of the opening device 3 and / or the package 1 according to the invention will be apparent from the above description.

[0100] In particular, by having one or more annular protruding elements 19, it is possible to improve the airtightness of the opening device 3 compared to conventional opening devices.

[0101] A further advantage is that the tightness is guaranteed independently of the actual position of the sealing lip 18 .

[0102] Another advantage is that the tightness is guaranteed whatever the shape of the sealing lip 18 .

[0103] However, modifications may be made to the opening device 3 and / or the package 1 described herein without departing from the scope of protection defined in the appended claims.
