Abstract
Description
Field of the Invention
[0001] The present invention relates to a spout for a package, in particular a package having a sealed body, filled with a pourable product, and even more particularly filled with a pourable foodstuff.
[0002] Advantageously, the present invention relates to a lid and spout assembly for a package, in particular a package having a sealed body, filled with a pourable product, and even more particularly filled with a pourable foodstuff.
[0003] Advantageously, the present invention also relates to a package, in particular a package having a sealed body, filled with a pourable product, and even more particularly filled with a pourable foodstuff, and comprising a spout. Background Art
[0004] Many liquid or pourable foodstuffs are known to be sold in packages, in particular sealed packages, made of aseptic packaging material. Examples include fruit juices, UHT (ultra-high temperature treated) milk, wine, tomato ketchup, etc.
[0005] A typical example is the parallelepiped package for pourable foodstuffs known as Tetra Brik Aseptic (registered trademark), which is made by sealing and folding a laminated strip of packaging material. The packaging material has a multi-layer structure, which includes a paperboard and / or paper base layer, covered on both sides with layers of heat-sealable plastic material (such as polyethylene). In the case of aseptic packages for long-term storage of products, the packaging material also includes a layer of oxygen barrier material, such as aluminum foil, which is stacked on a layer of heat-sealable plastic material and is in turn covered with another layer of heat-sealable plastic material, which forms the inner surface of the package that finally contacts the foodstuff.
[0006] Some known packages, in particular the corresponding sealed bodies of packages formed by packaging material, include designated pouring openings that allow a pourable product to be poured out of the package. Usually, the designated pouring openings are covered by a separating membrane that separates the interior of the package from the external environment and will be opened or removed or broken or cut or pierced before the first pouring of the pourable product, in order to allow the pourable product to be poured out through the designated pouring openings. It is also known to arrange a lid and spout assembly having a spout and a lid around the designated pouring opening on the body. The spout has a pouring outlet to allow the pourable product to be poured out of the package in a controlled manner, and the lid allows the pouring outlet to be selectively closed and opened.
[0007] The spout includes a collar that bears a pouring outlet at a first axial end and an inlet opening at a second axial end. After the integrity of the separating membrane is lost, the pourable product can be poured out of the interior space of the package by removing the lid from the spout. The pourable product flows from the interior space of the package through the inlet opening towards the pouring outlet. Once the lid is again arranged on the spout, the lid prevents the pourable product from flowing out of the pouring outlet. However, the pourable product can still flow into a flow channel extending between the inlet opening and the pouring opening of the collar depending on the orientation of the package.
[0008] A known type of lid and spout assembly is designed to prevent the possibility of the pourable product entering the flow channel when the lid closes the pouring outlet. Such a lid and spout assembly is provided with a spout that includes a closing element coupled to the lid by a coupling member. This closing element is fused to and / or at least partially defines the separating membrane and is positioned to seal the inlet opening. In particular, the closing element is configured to contact an edge portion of the collar that defines the inlet opening.
[0009] Typically, such a spout also includes a coupling membrane that connects the closing element to the edge portion and ruptures when the lid is first removed from the spout.
[0010] It is known to form such a package starting from a substantially flat packaging material that bears the spout, which is folded, filled with the pourable product and sealed. More specifically, the applicant has applied a technique that is based on the following: the packaging material is provided in the form of an annular web that is advanced within an automatic packaging machine. During the advancement, the spout is applied to the packaging material by molding, in particular injection molding. Then, the web is folded into a tube, longitudinally sealed, filled with the pourable product, and transversely sealed and cut to obtain individual packages. Finally, the lids are applied to the respective spouts.
[0011] It has been observed that during the formation, the spout is subjected to forces that can cause the spout to deform.
[0012] It has also been found that the presence of the coupling member can cause possible deformation of the closing element and a loss of the positioning accuracy of the closing element within the spout.
[0013] Therefore, there is a need in the art to improve such a spout in order to overcome the inconveniences encountered. Summary of the Invention

In particular, the central wall 31 is curved such that when the spout 4 is in the initial configuration, the center point of the central wall is arranged closer to the inlet opening 18 and / or the second edge 24 with respect to the central axis E than the peripheral portion 30.
[0107] Alternatively, when the spout 4 is in the initial configuration, the central wall 31 is curved towards the pouring outlet 12 and / or the first edge 23. In particular, according to this alternative, the central wall 31 is curved such that when the spout 4 is in the initial configuration, the center point of the central wall is arranged closer to the pouring outlet 12 and / or the first edge 23 with respect to the central axis E than the peripheral portion 30.
[0108] Advantageously, before the first actuation of the closing element 14 from the active position to the inactive position (i.e., when the spout 4 is in the initial configuration), the peripheral portion 30 contacts and is frangibly fixed to the inner surface 21 along the initial contact portion 32 (particularly having an annular shape) of the inner surface 21.
[0109] In particular, by the contact of the peripheral portion 30 with the inner surface 21, a sealing effect is achieved at the interface between the peripheral portion 30 and the inner surface 21.
[0110] According to some non - limiting embodiments, the initial contact portion 32 is arranged such that the inner surface 21 includes:
[0111] - A main surface portion 33 that extends (and extends to the pouring outlet 12 and / or the first edge 23) from the initial contact portion 32 towards the pouring outlet 12 and / or the first edge 23; and
[0112] - An auxiliary surface portion 34 that extends from the initial contact portion 32 towards the inlet opening 18 and / or the second edge 24 and extends to the inlet opening 18 and / or the second edge 24.
[0113] In particular, the initial contact portion 32 is axially displaced (with respect to the central axis E) from the inlet opening 18 and / or the second edge 24 and towards the pouring outlet 12 and / or the first edge 23.
[0114] Preferably, the initial contact portion 32 is also axially displaced with respect to the central axis E from the second annular portion 29 and towards the pouring outlet 12 and / or the first edge 23.
[0115] Preferably, the initial contact portion 32 is located in a third plane H3 (in particular different from and parallel to the first plane H1 and the second plane H2). In particular, the third plane H3 is perpendicular to the central axis E.
[0116] In particular, the third plane H3 is between the first plane H1 and the second plane H2.
[0117] According to some preferred non - limiting embodiments, the axial distance (with respect to the central axis E) between the second plane H2 and the third plane H3 is greater than the thickness of the peripheral portion 30. In particular, the axial distance is at least twice, preferably at least three times, and even more particularly at least four times the thickness of the peripheral portion 30.
[0118] According to some preferred non - limiting embodiments, the collar 13 includes a main portion 35 having a main surface portion 33 and an auxiliary portion 36, particularly of an annular shape, having an auxiliary surface portion 34.
[0119] Preferably, the main surface portion 33 and the auxiliary surface portion 34 respectively define and / or delimit a main space 37 and an auxiliary space 38 of the flow channel 20.
[0120] In particular, the closing element 14 is configured to prevent any pourable product from entering the main space 37 when the arrangement is in the active position.
[0121] In particular, the auxiliary space 38 has a cylindrical shape.
[0122] Preferably, the main space 37 has a frustoconical-shaped portion, in particular a portion that tapers towards the inlet opening 18 and / or the second edge 24.
[0123] According to some preferred non-limiting embodiments, the auxiliary surface portion 34 is transverse to the main surface portion 33. In particular, the auxiliary surface portion 34 is parallel to the central axis E and the main surface portion 33 is transverse to the central axis E.
[0124] Preferably, the first inclined surface of the auxiliary surface portion 34 and the second inclined surface of the main surface portion 33 are such that the initial contact portion 32 defines a plurality of inflection points. In particular, the first inclined surface and the second inclined surface are defined with respect to an intersecting plane including the longitudinal axis E (i.e., the longitudinal axis E lies on the intersecting plane and the longitudinal axis E and the intersecting plane are parallel to each other). The intersecting plane intersects the inner surface 21 to obtain a one-dimensional curve (in particular, two one-dimensional curves because the intersecting plane intersects two different portions of the inner surface 21). Each one-dimensional curve includes a first portion and a second portion located on the auxiliary surface portion 34 and the main surface portion 33, respectively. The corresponding intersection points between the first portion and the second portion correspond to the corresponding points of the initial contact portion 32. Preferably, each intersection point is an inflection point of the corresponding one-dimensional curve.
[0125] According to some preferred non-limiting embodiments, the inner surface 9 and the outer surface 10 are respectively arranged in a fourth plane H4 and a fifth plane H5, in particular transverse to, and even more particularly perpendicular to, the central axis E, especially arranged at the designated pouring outlet.
[0126] Preferably, the third plane H3 is axially spaced from the fifth plane H5.
[0127] Preferably, the third plane H3 coincides with the fifth plane H5 or is axially displaced from the fifth plane H5 with respect to the central axis E and towards the pouring outlet 12.
[0128] According to some preferred non-limiting embodiments, the spout 4, in particular the closing element 14, and even more particularly the peripheral portion 30, further includes a coupling membrane 39 that fixes the closing element 14 to the inner surface 21 in a frangible manner, especially when the spout 4 is in the initial configuration, or in other words, before the first control of the closing element 14 from the active position to the inactive position. In particular, the coupling membrane 39 ensures the sealing of the internal space 8 before the first control of the closing element 14 from the active position to the inactive position.
[0129] Preferably, the coupling membrane 39 is configured to irreversibly rupture during the first removal of the closing element 14 from the inner surface 21, especially during the first control of the closing element 14 from the active position to the inactive position (see Figures 4 to 6)。This means that after the coupling membrane 39 ruptures, the closing element 21 remains in contact with the inner surface 21 while no longer being fixed to the inner surface 21. This ensures that each time the closing element 14 is arranged again within the flow channel 20, and in particular each time the closing element 14 is arranged again in the active position, the fluid connection between the inlet opening 18 and the pouring outlet 12 (see Figure 6 ) is interrupted.
[0130] In use, the user receives the package 1 with the lid 5 and the closing element 14 in the closed configuration and the active position respectively so as to cover the pouring outlet 12 and prevent any fluid connection between the inlet opening 18 and the pouring outlet 12.
[0131] Before the first actuation of the lid 5 from the closed configuration to the open configuration and of the closing element 14 from the active position to the inactive position, the peripheral portion 30 contacts the initial contact portion 32. In particular, the sealing effect obtained is (initially) ensured by the coupling membrane 39.
[0132] To access the pourable product, the user needs to actuate the lid 5 from the closed configuration to the open configuration, which results in actuating the closing element 14 from the active position to the inactive position, thereby allowing the pourable product to flow from the internal space 8 through the inlet opening 18 into the flow channel 20 and out of the flow channel 20 through the pouring outlet 12.
[0133] When the closing element 14 is first moved from the active position to the inactive position, the coupling membrane 39 ruptures irreversibly.
[0134] The lid 5 and the closing element 14 can be reversibly actuated in the closed configuration and the open configuration and in the active position and the inactive position respectively so as to selectively control whether to prevent or allow the outflow of the pourable product.
[0135] Each time the closing element 14 is arranged again in the active position, the closing element 14 remains arranged between the pouring outlet 12 and the inlet opening 18. In particular, the peripheral portion 30 contacts the contact portion of the inner surface 21. The contact portion can correspond to but can also deviate from the initial contact portion 32.
[0136] In particular, when the closing element 14 is in the active position, the closing element 14 interrupts the fluid connection between the inlet opening 18 and the pouring outlet 12.
[0137] Reference Figure 6 , the reference numeral 4' denotes an alternative embodiment of the spout of the lid and spout assembly 3 according to the invention; since the spout 4' is similar to the spout 4, the following description is limited to the differences between them and, where possible, the same reference numerals are used for the same or corresponding parts.
[0138] In particular, the spout 4' differs from the spout 4 in that the auxiliary part 36 includes at least one annular cover 46 which is connected to the main part 35 and projects from the main part 35 towards the inlet opening 18. Preferably, the annular cover 46 delimits a part of the auxiliary space 38 which in particular has a frustoconical shape. Preferably, a part of the auxiliary space 38 tapers towards the inlet opening 18 and / or the second edge 24. In particular, this also means that the auxiliary space 38 does not have a cylindrical shape as in the case of the spout 4.
[0139] In particular, the auxiliary surface part 34 is transverse to the central axis E.
[0140] Preferably, the terminal edge 47 of the annular cover 46 is inserted between the inlet opening 18 and the initial contact part 32 (in other words, the terminal edge 47 is inserted between the second plane H2 and the third plane H3).
[0141] According to some preferred non-limiting embodiments, the auxiliary part 36 further includes an end part 48 which is connected to the annular cover 46 and bears the second edge 24. In particular, the end part 48 delimits another part of the auxiliary space 38 which in particular also has a frustoconical shape. In particular, another part of the auxiliary space 38 tapers from the inlet opening 18 towards the initial contact part 32.
[0142] Preferably, the minimum diameter of the end part 48 is greater than the diameter of the annular cover 46 at the terminal edge 4.
[0143] Since the operation of the package 1 with the spout 4' is similar to the operation of the package 1 with the spout 4, reference is made to the description provided above.
[0144] Reference Figure 7 , the reference numeral 4” denotes an alternative embodiment of the spout of the cap and spout assembly 3 according to the invention; since the spout 4” is similar to the spout 4, the following description is limited to the differences between them and the same reference numerals are used for the same or corresponding parts where possible.
[0145] In particular, the spout 4” differs from the spout 4 in that the closing element 14 further includes a contact ring 49 which is connected to the peripheral part 30 and projects from the peripheral part 30. Advantageously, the contact ring 49 is configured to contact the inner surface 21 when the cap 5 is in the active position, in particular to increase the sealing surface between the closing element 14 and the inner surface 21.
[0146] According to some preferred non-limiting embodiments, the contact ring 49 extends from the peripheral part 30 towards the top wall 25.
[0147] In particular, the spout 4" also differs from the spout 4 in that the auxiliary part 36 further includes an annular limiting lip 50 disposed between the initial contact part 32 and the inlet opening 18. In particular, the annular limiting lip 50 protrudes towards the center of the auxiliary part 36.
[0148] Preferably, the diameter of the annular limiting cover 50 is smaller than the diameter of the auxiliary part 36 at the second edge 24.
[0149] Since the operation of the package 1 with the spout 4" is similar to the operation of the package 1 with the spout 4, reference is made to the description provided above.
[0150] The advantages of the spout 4, spout 4', spout 4" and / or the lid and spout assembly 3 and / or the package 1 according to the present invention will be apparent from the foregoing description.
[0151] In particular, by disposing the closing element 14 within the flow channel 20 and between the pouring outlet 12 and the inlet opening 18 (i.e., moving the closing element 14 away from the second edge 24 and towards the pouring outlet 12 relative to the solutions known in the prior art), a spout 4 or spout 4' or spout 4" is obtained, which increases the stability. Thus, the lid and spout assembly 3 is more stable during the formation of the package 1 within an automatic machine.
[0152] Another advantage is that by arranging the main surface part 33 and the auxiliary surface part 34 transversely to each other, a more precise cutting and / or rupture of the separating membrane and / or the closing element 14 can be obtained; and / or the control of the base frame 15 can be improved.
[0153] Yet another advantage is that the axial distance between the closing element 14 and the top wall 25 is smaller, which means that the coupling member 16 is shorter compared to the solutions known in the art. This also means that the deformation of a single coupling member 16 is smaller, thus increasing the stability of the closing element 14.
[0154] A further advantage is that due to the short coupling member 16, the amount of polymer required to form the spout 4 or spout 4' or spout 4" is reduced.
[0155] Even further advantage is that even in the case of deformation of the position of the closing element 14 (in the solutions known in the art, the position deformation would result in the formation of a fluid connection between the internal space 8 and the pouring outlet 12), the sealing effect of the closing element 14 is also improved due to the contact of the closing element 14 with the inner surface 21.
[0156] Obviously, changes can be made to the spout 4, spout 4', spout 4" and / or the lid and spout assembly 3 and / or the package 1 as described herein without departing from the scope of protection defined by the appended claims.
[0157] According to an alternative embodiment not shown, the control of the lid 5 between the closed configuration and the open configuration and thus the control of the closing element 14 between the active position and the inactive position are achieved by means of a screwing movement on the lid 5.
[0158] According to an alternative embodiment not shown, the spout 4 or the spout 4' may include a contact ring 49.
[0159] According to an alternative embodiment not shown, the spout 4 or the spout 4' may include a limiting ring 50.
