A closure assembly (3) is described for a container (1) filled or refillable with a pourable product comprising at least a lid (8) having a first rim (27), an annular member (9) having a second rim (29) facing the first rim (27), and one or more coupling elements (10), each of which is connected to the lid (8) and the annular member (9).

Description

Container that has a locking assembly TECHNICAL FIELD The present invention relates to a closure assembly for a container, in particular, a container filled or fillable with a pourable product, even more particularly, a container filled or fillable with a pourable food product. The present invention also relates to a container filled or fillable with a pourable product, even more particularly, a container filled or fillable with a pourable food product, having a closure assembly. BACKGROUND OF THE TECHNIQUE As is known, many liquid or pourable food products, such as fruit juice, UHT milk (treated at ultra-high temperatures), wine, tomato sauce, etc., are sold in containers, such as composite containers, bottles, cans, and the like. Furthermore, it is known that such containers are often provided with a closure assembly to selectively allow the pouring of the pourable product from the container. A typical closure assembly comprises a neck, which is connected to the container, having a pouring outlet that allows the pourable product to flow from the container, and a lid configured to selectively open and close the pouring outlet and which is connected to the neck when the pouring outlet is closed. It is also known that the locking assembly normally comprises an annular element coupled to and surrounding the neck. The axial movement of the annular element along the neck is normally limited by an annular flange that projects radially from the neck to ensure that the annular element remains coupled to the neck. Furthermore, before the cap is removed for the first time, the ring element and the cap are connected by connecting bridges, which break during the first removal of the cap from the neck. After the first removal of the cap from the neck, the ring element and the cap separate. Closure assemblies are known from EP 3868680 A1. One drawback is that the lid is disconnected from the ring element, so when the lid is removed from the neck to open the pouring spout, the lid separates from the container. This means, for example, that a user needs to hold the lid in one hand and the container in the other. Furthermore, this can lead to the lid becoming undesirably dirty. To overcome these drawbacks, it has been proposed to attach the lid to the ring element using a connecting element. Although these closure assemblies work satisfactorily, there is a desire within the industry to further improve them. DISCLOSURE OF THE INVENTION Therefore, an objective of the present invention is to provide in a simple and economical manner a closure assembly for containers, in particular, filled or fillable with a pourable product, even more particularly, filled or fillable with a pourable food product. Advantageously, an additional objective of the present invention is to provide in a simple and economical manner an improved closure assembly for containers, which is accompanied by minimal pressure acting on the annular elements during the handling of the respective lids. Advantageously, another objective of the present invention is to provide in a simple and economical manner a container, in particular, filled or fillable with a pourable product, even more particularly, filled or fillable with a pourable food product, having a closure assembly, which is accompanied by a minimum pressure acting on the annular elements during the handling of the respective lids. According to the present invention, a closure assembly is provided according to separate claim 1. The dependent claims specify additional advantageous embodiments of the locking assembly. According to the present invention, a container is also provided according to claim 13.

BEST WAYS TO CARRY OUT THE INVENTION Number 1 indicates a container, such as a bottle, a composite container, a can, or the like, comprising a main body 2 and a closure assembly 3 attached or attachable to the main body 2. Preferably, but not necessarily, container 1 is filled or can be filled with a pourable product, in particular, a pourable food product, even more particularly, a pourable food product that is sterilized and / or processed in a sterile state, such as fruit juice, milk (e.g., ultra-high temperature treated milk), water, wine, tomato sauce, sugar, salt, and others. The following description will refer to composite containers 1, in particular to containers 1 whose main body 2 is obtained from a strip of packaging material having a multi-layer structure, although this is not intended to limit the scope of protection as defined in the attached claims. In particular, the packaging material band comprises at least one layer of fibrous material, such as, for example, a layer of paper or cardboard, and at least two layers of heat-sealed plastic material, for example, polyethylene, with the fibrous material layer sandwiched between them. One of these two layers of heat-sealed plastic material, which defines the inner face of the main body 2, comes into contact with the pourable product. Preferably, but not necessarily, the packaging material band also comprises a gas and light barrier layer, for example, aluminum foil or ethylene-vinyl alcohol (EVOH) film, specifically positioned between one of the heat-sealed plastic layers and the fibrous material layer. Preferably, but not necessarily, the packaging material band also comprises an additional heat-sealed plastic layer interposed between the gas and light barrier layer and the fibrous material layer. According to a preferred, non-limiting embodiment, the main body 2 defines a sealed container, in particular a sealed carton container, having a designated pouring opening surface area (not shown and referred to as such), and the closure assembly 3 fits the main body 2, in particular around the designated pouring opening surface area. According to a preferred, non-limiting embodiment, the closure assembly(s) 3 is applied to the aforementioned main body(s) 2, during or after the formation, filling and sealing of the main body(s) 2 by means of a molding and / or adhesive bonding and / or ultrasonic bonding process. Alternatively, the closure assembly(s) 3 can be applied to the packaging material web before or during the advance of the packaging material web within a packaging machine to form, fill, and seal the main body(ies) 2 from the packaging material web. With particular reference to Figure 1, the main body 2 extends along a longitudinal axis A, a first transverse axis B, and a second transverse axis C. In particular, axis A is perpendicular to axis B, and axis C and axis B and axis C are perpendicular to each other. Preferably, but not necessarily, the extension of the main body 2 along axis A is greater than the extension of the main body 2 along axis B and axis C. Preferably, but not necessarily, the main body 2 has a parallelepiped shape. According to the disclosed non-limiting embodiment, the main body 2 comprises a first wall portion, in particular transverse, and more specifically, perpendicular to axis A, from which the main body 2 extends along axis A. Preferably, but not necessarily, the first wall portion defines a support surface for the container 1, in particular the main body 2, which, during use, can come into contact with a support, such as, for example, a shelf, when displayed at a point of sale or when stored. In particular, when placed on a support and / or, during use, when a consumer of the container 1 consumes the pourable product, the first wall portion defines a bottom wall portion. Preferably, but not necessarily, the main body 2 also comprises a plurality of side walls 4 that are (fixedly) connected to the first wall part and extend, in particular, substantially parallel to axis A, from the first wall part. Preferably, but not necessarily, the main body 2 also comprises at least a second wall portion 5 opposite the first wall portion and (fixedly) connected to the side walls 4. In other words, the side walls 4 are interposed between the first wall portion and the second wall portion 5. In particular, when mounted on a support and / or, during use, when a consumer of the container product 1 consumes the pourable product, the second wall portion 5 defines an upper wall portion. According to some non-limiting embodiments, the first wall portion and the second wall portion 5 may be parallel to each other. Alternatively, the first wall portion and the second wall portion 5 may be inclined to each other. According to some non-limiting embodiments, the second part of wall 5 comprises the designated pouring opening surface area. According to a preferred, non-limiting embodiment, the designated pouring opening surface area of ​​the main body 2 comprises a pouring hole that allows the pourable product to exit the main body 2. According to a preferred, non-limiting embodiment, the surface area of ​​the designated pouring opening also comprises a separating membrane that seals the pouring orifice. Specifically, the separating membrane is configured to retain the pourable product within the main body 2 when intact and to be at least partially (and irreversibly) opened, torn, cut, and / or punctured to allow the pourable product to exit the main body 2 through at least a portion of the pouring orifice. In particular, the separating membrane is configured to allow the pourable product to exit after it has lost its integrity and to protect the pourable product from the external environment before it is cut, opened, torn, and / or punctured. Preferably, but not necessarily, the separation membrane comprises a gas and light barrier material, for example, aluminum foil or ethylene-vinyl alcohol (EVOH) film. According to a preferred, non-limiting embodiment, the separation membrane is defined by a part of the packaging material strip, in particular, a part of the layers of the packaging material strip is different from the fibrous material layer. According to a preferred, non-limiting embodiment, the closure assembly 3 comprises, and / or is formed from, a polymeric material. Alternatively, the closure assembly 3 could comprise, and / or be formed from, a metallic material. With particular reference to Figures 1 to 4, closure assembly 3 comprises at least one closure group 7 having at least: - a lid 8; - an annular element 9; and - one or more connecting elements 10, in the specific case shown two connecting elements 10, connected to the cover 8 and the ring member 9. Preferably, the closure group 7 is molded as a single piece from a molten polymer. It should be noted that the connecting elements 10 are connected to the cap 8 and the ring element 9 in a breakable and / or at least separable manner. This means that, after normal use of the closure assembly 3, the connecting elements 10 remain connected to the cap 8 and the ring element 9. In particular, the connecting elements 10 are connected to the cap 8 and the ring member 9 to withstand an actuating force that exceeds the forces normally experienced during normal use of the closure assembly 3. An example of such a higher actuating force occurring is when a user intentionally attempts to separate the connecting elements 10 from the cap 8 and / or the ring element 9 by pulling the cap 8 and the ring element 9 in opposite directions. In particular, the connecting elements 10 hold together the plug 8 and the annular element 9. According to some preferred, non-limiting embodiments, the closure assembly 3 also comprises one or more first breakable connecting bridges 11 that connect the annular element 9 and the cap 8. In particular, and as explained in more detail below, the first connecting bridges 11 are configured to break during a first handling of the cap 8 (by a consumer). According to the invention, the closure assembly 3 also comprises a safety ring 12 and one or more second breakable connecting bridges 13 that connect the safety ring 12 and the annular element 9. In particular, and as explained in more detail below, the second connecting bridges 13 are configured to break during the first handling of the lid 8. In particular, the annular element 9 is interposed between the cover 8 and the safety ring 12. According to some non-limiting embodiments, the closure assembly 3 also comprises a neck 14 that delimits and / or defines and / or has a pouring outlet 15, the pouring outlet 15 being configured to allow the pourable product to exit the container 1. In particular, neck 14 is arranged around the pouring hole. According to some non-limiting preferred embodiments, the neck 14 extends along a longitudinal axis E. In particular, the neck 14 has an annular shape, specifically an annular cross-sectional shape with respect to a sectional plane that is orthogonal to the longitudinal axis E. In particular, the neck 14 defines and / or delimits and / or comprises a flow channel for the pourable product. More specifically, the flow channel is interposed and / or is designed to be interposed between the pouring outlet 15 and the pouring orifice. According to some non-limiting embodiments, the ring element 9 and / or the safety ring 12 is (n) mounted on the neck 14 and arranged (s) around it. Preferably, the second annular element 9 and / or the safety ring 12 are coaxial to the neck 14. Preferably, the lid 8 is connected and / or connectable to the neck 14 and is configured to selectively close and open the pouring outlet 15 to prevent and allow respectively the pourable product to exit from the container 1 through the pouring outlet 15. According to some non-limiting preferred embodiments, the lid 8 is controllable in at least one closed position (see Figures 1 to 4) in which the lid 8 closes and / or is configured to close the pouring outlet 15 and an open position (not shown) in which the lid 8 opens and / or is configured to open the pouring outlet 15. Preferably, but not necessarily, the cover 8 is controlled in the closed and open positions by being attached to and detached from the neck 14, respectively. In particular, the cover 8 is coaxial with the neck 14 and / or the pouring outlet 15 when controlled in the closed position, and preferably, but not necessarily, transverse to the neck 14 when controlled in the open position. In other words, when the cover 8 is in the closed position, it is connected to the neck 14 and covers the pouring outlet 15, and when the cover 8 is in the open position, it is detached from the neck 14 and clears the pouring outlet 15. In more detail, in the specific example disclosed, the cap 8 is controlled between the closed and open positions by means of a screw-on action. In particular, the cap 8 comprises an internal threaded portion, specifically arranged on an inner surface of the cap 8, and the neck 14 comprises an externally threaded portion, specifically arranged on an outer surface of the neck 14. Preferably, the internal threaded portion and the external threaded portion are configured to allow selective tightening and loosening of the cap 8 and the neck 14 by means of relative rotation between the cap 8 and the neck 14. According to some non-limiting embodiments, the threaded inner part and / or the threaded outer parts define a cam mechanism. It should be noted that before the first check (first handling) of the lid 8 from the closed position to the open position, the first connecting bridges 11 connect the annular element 9 and the lid 8 to each other and, during use, during the first time that the lid 8 is checked from the closed position to the open position, the first connecting bridges 11 are irreversibly broken. In particular, and equivalently, the second connecting bridges 13 connect the annular element 9 and the safety ring 12 before the first check of the lid 8 from the closed position to the open position and, during use, during the first time the lid 8 is checked from the closed position to the open position, the second connecting bridges 13 are irreversibly broken. According to some non-limiting embodiments, the closure assembly 3 further comprises a coupling base 16 that carries the neck 14 and is configured to couple and / or connect and / or is coupled and / or connected to the main body 2. Preferably, but not necessarily, the coupling base 16 is configured to be fixed and / or is fixed to an outer surface of the main body 2, in particular, the second wall part 6. In particular, the coupling base 16 is arranged in the area of, even more particularly in, the surface area of ​​the designated pouring opening. In particular, the coupling base 16 comprises an opening, and the neck 14 surrounds the opening so that, during use, by opening and / or cutting and / or breaking and / or piercing the separation membrane, a fluid connection is established between the inside of the main body 2 and the pouring outlet 15 (i.e., the pourable product can come out of the container 1). Preferably, but not necessarily, at least part of the junction base 16 (substantially) has a plate-like configuration. According to some non-limiting preferred embodiments, the closing assembly 3, in particular the neck 14, comprises an interaction device configured to interact with the annular element 9 to prevent the annular element 9 from disengaging from the neck 14. In particular, the interaction device is configured to limit axial movement of the annular element 9 along the longitudinal axis E. In more detail, the interaction device comprises, in particular, an annular flange 17 projecting (radially) from the neck 14. Specifically, the annular flange 17 projects (radially) from an outer surface of the neck 14 and away from it. According to some non-limiting preferred embodiments, the annular flange 17 has a continuous form. Alternatively, the annular flange 17 could have a discontinuous form (e.g., the annular flange 17 could be formed from a multitude of individual pieces projecting from the neck 14). According to some non-limiting preferred embodiments, the closing assembly 3 comprises an interaction unit, in particular coupled to the neck 14, configured to interact with the annular element 9 and / or the safety ring 12 to activate the breaking of the first connecting bridges 11 and / or the second connecting bridges 13 during the first time the lid 8 is checked from the closed position to the open position. With particular reference to Figure 2, the closure assembly 3 also comprises a cutting device 18 configured to break and / or pierce and / or cut and / or open the separation membrane and a control device configured to control the cutting device 18 from a rest position to an operating position in which the cutting device 18 is adapted to break and / or pierce and / or cut and / or open the separation membrane. Preferably, but not necessarily, the cutting device 18 has an annular shape and is disposed within the flow channel of the neck 14 when disposed in the rest position and protrudes at least partially outside the flow channel when controlled in the operating position. In particular, the cutting device 18 is arranged in the rest position before the first time the lid 8 is controlled from the closed position to the open position and is arranged in the operating position after the first control of the lid 8 to the open position. Preferably, but not necessarily, the cutting device 18 is in an axially elevated position (with respect to the longitudinal axis E) when arranged in the rest position and with respect to the operating position. According to the invention, the control device comprises control flaps 19, in particular, connected to a cap 8, interaction elements 20 connected to the cutting device 18, and a cam mechanism 21 (see Figure 2; referred to as such and not described in detail) partially associated with the cutting device 18 and partially associated with the neck 14. According to the invention, the cam mechanism 21 may comprise respective threaded parts. Preferably, but not necessarily, the control device is configured to be activated during the first movement of the lid 8 from the closed position to the open position to (irreversibly) move the cutting device 18 from the rest position to the operating position. With particular reference to Figures 1 to 4, the annular element 9 comprises a central axis F. In particular, the central axis F is parallel, even more particularly coaxial, to the longitudinal axis E with the annular element 9 and / or the closing assembly 3 coupled to the neck 14. In particular, the central axis F defines a central axis of the closing group 7. Preferably, the cover 8 is coaxial to the annular element 9 and / or the central axis F with the cover 8 arranged in the closed position. Preferably, the safety ring 12 is coaxial to the annular element 9 and / or the central axis F. With particular reference to Figures 1 to 4, cover 8 comprises: - an upper wall 25 configured to cover the pouring outlet 15, with the lid 8 in the closed position; and - a side wall 26 projecting (axially) from the top part 25 and, in particular, configured to surround at least partially the neck 14, the lid 8 being controlled in the closed position. Preferably, the side wall 26 has a respective annular cross-section profile, in particular, with respect to a cross-section plane perpendicular to the longitudinal axis E and / or the central axis F and with the cover 8 in the closed position. In particular, with cover 8 in the closed position, the top wall 25 is transverse, in particular, perpendicular to the central axis F and the side wall 26 is (substantially) parallel to the longitudinal axis E and / or the central axis F. According to some possible non-limiting embodiments, the cover 8, in particular the top wall 25 and / or the side wall 26, is attached to and separated from the neck 14 when the cover 8 is, during use, in the closed position and in the open position, respectively. According to some preferred, non-limiting embodiments, the cover 8, in particular the side wall 26, comprises a first edge 27. In particular, the first edge 27 delimits an opening in the cover 8 opposite the top wall 25. The first edge 27 may comprise a first surface 28. In more detail, the first surface 28 extends within a first plane, in particular, the first plane being perpendicular to the longitudinal axis E and / or the central axis F, with the cap 8 in the closed position. According to some non-limiting preferred embodiments, the annular element 9 comprises a second edge 29 opposite the first edge 27, in particular, with the cap 8 in the closed position. The second edge 29 can have a second surface 30 opposite the first surface 28. In more detail, the second surface 30 extends into a second plane. Preferably, the second plane is parallel to the first plane, particularly when the lid 8 is in the closed position. With particular reference to Figures 2 to 4, each connecting element 10 comprises at least: - a respective intermediate (linear) part 35; - a respective first curved part 36 connected to the lid, in particular to the first edge 27, even more particularly to the first surface 28, and to the intermediate part 35; and - a respective second curved part 37 connected to the ring member 9, in particular, to the second edge 29, even more particularly, to the second surface 30, and to the intermediate part 35. In other words, each connecting element 10 comprises an intermediate part 35 interposed between the first curved part 36 and the second curved part 37. In more detail, each intermediate part 35 comprises a first end 38 and a second end 39 opposite the first end 38. Preferably, the intermediate part 35 extends (substantially and) linearly between the first end 38 and the second end 39. In particular, the first curved part 36 is connected to the first end 38 and the second curved part 37 is connected to the second end 39. Preferably, each connection element 10 is S-shaped. Advantageously, each intermediate part 35 is inclined with respect to the lid 8 and / or is not parallel to it, in particular, to the first edge 27, even more particularly, to the first surface 28, preferably in the absence of any tension and / or external forces acting on the locking assembly 3 (as a possible result of manipulation of the locking assembly 3 by a user). Alternatively, or additionally, each intermediate part 35 is inclined with respect to the ring member 9 and / or is not parallel to it, in particular, to the second edge 29, even more particularly, to the second surface 30, preferably in the absence of any stress and / or external forces acting on the closure assembly 3 (as a possible result of manipulation of the closure assembly 3 by a user). Preferably, each intermediate part 35 is inclined with respect to the first plane and / or the second plane and / or is not parallel to them, particularly in the absence of any tension and / or pressure and / or external forces acting on the closure assembly 3 (as a possible result of manipulation of the closure assembly 3 by a user). In other words, each intermediate part 35 comprises at least two imaginary linear projections 40, one extending linearly from and away from the first end 38 and the other extending linearly from and away from the second end 39. In particular, the imaginary linear projections 40 intersect with the foreground and / or background plane. According to some non-limiting preferred embodiments, each intermediate part 35 is inclined with respect to the central axis F and / or the longitudinal axis E. In particular, each intermediate part 35 is transverse, but not perpendicular to the central axis F and / or the longitudinal axis E (i.e., each intermediate part 35 describes with the central axis F and / or the longitudinal axis E an angle ranging from 0° to 90°, excluding 0° and 90°). Preferably, the closure assembly 3 comprises an intermediate space 41 arranged between and / or delimited by the cover 8, in particular, the first edge 27, even more particularly, the first surface 28, and the annular element 9, in particular, the second edge 29, even more particularly, the second surface 30, and each connecting element 10 is positioned within the intermediate space 41. With particular reference to Figures 2 to 4, each first curved part 36 is connected to the first edge 27, in particular to the first surface 30, at a respective first position 42, and each second curved part 37 is connected to the second edge 29, in particular to the second surface 30, at a respective second position 43. Advantageously, each first position 42 and the respective second position 43 are angularly, in particular also axially, displaced from each other, in particular around (and along) the central axis F. In particular, the first positions 42 are also angularly displaced from each other, and the second positions 43 are also angularly displaced from each other. According to some non-limiting preferred embodiments, each first curved part 36 is convex with respect to the annular element 9 and each second curved part 37 is concave with respect to the annular element 9. In other words, each first curved part 36 is concave with respect to the cover 8 and each second curved part 37 is convex with respect to the cover 8. In particular, each first curved part 36 is curved towards (points towards) the annular element 9 and each second curved part 37 is curved towards (points towards) the cap 8. Advantageously, each connecting element 10 is elastically deformable, in particular so that the connecting elements 10 act during use and during handling and / or manipulation of the closing assembly 3, in particular the closing group 7, (for example, movement of the lid 8 from the closed position to the open position) as spring elements. In more detail, each first curved part 36 comprises a first engagement surface 44 and each second curved part 37 comprises a second engagement surface 45. Preferably, each connecting element 10 is deformable so as to allow the respective first engagement surface 44 to abut against (a respective first abutment part of the first edge 27, in particular, of the first surface 28 of) the cover 8 and the second engagement surface 45 to abut against (a second abutment part of the second edge 29, in particular, of the second surface 30 of) the annular element 9. In other words, each first engagement surface 44 and each second engagement surface 45 are adapted to engage respectively with the respective first stop part and the respective second stop part, in particular, during handling and / or manipulation of the locking assembly 3, and even more particularly, during handling and / or manipulation of the locking group 7. In particular, during use, each engagement surface 44 and each engagement surface 45 engage respectively with the respective first stop part and the respective second stop part during the removal of the locking group 7 from a molding tool and / or during the assembly of the locking group 7 into the neck 14. Furthermore, during use, the connecting elements 10 may deform as a result of pressure, stress, and / or forces acting during the handling and / or manipulation of the closing assembly 3, in particular the closing group 7 (for example, moving the lid 8 from the closed to the open position). During use, a consumer manipulates the closing assembly 3, in particular the closing group 7, to selectively open and close the pouring outlet 15 by controlling the lid 8 in the open or closed position. In particular, before the first manipulation of the closing assembly 3, specifically the closing group 7, the lid 8 is in the closed position and the first connecting bridges 11 and preferably also the second connecting bridges 13 are intact (i.e., not broken). The first time the lid 8 is moved from the closed position to the open position, the first connecting bridges 11 and preferably also the second connecting bridges 13 are irreversibly broken. In this way, the connecting elements 10 ensure that the cap 8 and the ring element 9 remain connected (secured) to each other. Additionally, this means that the cap 8 is attached to the neck 14 by means of the ring element 9. Furthermore, the tamper-evident ring 12 separates from the ring element 9, providing evidence of tampering. Furthermore, during the initial movement of lid 8 from the rest position to the operating position, the cutting device 18 is activated, specifically for cutting, piercing, opening, and / or breaking the separating membrane. During the operation of the closing assembly 7, particularly the movement of lid 8 between the closed and open positions, the connecting elements 10 deform elastically, thereby at least partially absorbing the external stresses and / or forces acting on the closing assembly 3 and / or the closing group 7. On the other hand, each first attachment surface 44 and each second attachment surface 45 can respectively abut against the relative first stop part and the relative second stop part. The advantages of the closure assembly 3 according to the present invention will become clear from the above description. In particular, the connecting elements 10 allow any pressure and / or tension and / or force acting on the closing assembly 3 to be dampened, in particular, the closing group 7. Another advantage has been observed in that the handling and / or manipulation of the locking assembly 3, in particular the locking group 7, is more convenient. Furthermore, by providing more than one connecting element 10, it is possible to increase the clamping force between the annular element 9 and the cover 8. Another advantage relates to the mounting of the closure group 7 on the neck 14. To mount the closure group 7 on the neck 14, the closure group 7 is forced onto the neck 14. In this way, the connecting elements 10 absorb at least a portion of the acting forces, thus reducing the risk of possible deformation of the neck 14 and / or the container 1 and / or the closure group 7. In particular, each first engagement surface 44 and each second engagement surface 45 abut against the cover 8 and the annular element 9, respectively. The applicant has also noted that the specific shape of the connecting elements 10 allows for the design of longer-lasting molding tools compared to connecting elements 10 with other shapes. In particular, the specific shape and size of the connecting elements 10 allow for the creation of molding tools with parts that define the connecting elements 10, and these parts have dimensions that provide a longer service life. Likewise, during the demolding of the closing group 7 of the molding tool, the first gripping surface 44 and the second gripping surface 45 abut against the cap 8 and the annular element 9, respectively, thus limiting deformation. Obviously, changes can be made to the container 1 and / or the closure assembly 3 as described herein without, however, departing from the scope of protection as defined in the appended claims.
