Description

Technical Field

[0001] The present invention relates to a closure assembly for containers, particularly for containers filled with or capable of being filled with pourable products, and even more specifically for containers filled with or capable of being filled with pourable food.

[0002] The present invention also relates to a container filled with or capable of being filled with a pourable product, and more specifically to a container filled with or capable of being poured with food having a closure component. Background Technology

[0003] As is well known, many liquid or pourable foods, such as juice, UHT (ultra-high temperature) milk, wine, and ketchup, are sold in containers such as composite packaging, bottles, cans, and jars.

[0004] It is also known that such containers are typically equipped with closure components to selectively allow pourable products to be poured out of the container.

[0005] Typical closure components include: a collar that is attached to a container having a pouring outlet that allows pourable product to be poured out of the container; and a cap that is configured to selectively open and close the pouring outlet and is attached to the collar when the pouring outlet is closed.

[0006] It is also known that the closure assembly typically includes an annular member coupled to and surrounding the collar. The axial movement of the annular member along the collar is typically limited by an annular ridge projecting radially from the collar to ensure that the annular member remains coupled to the collar.

[0007] Furthermore, before the first removal of the cap, the annular member and the cap were connected to each other by a coupling bridge, which broke during the first removal of the cap from the collar. After the first removal of the cap from the collar, the annular member and the cap separated from each other.

[0008] The inconvenience lies in the fact that the cap is disconnected from the ring member, so when the cap is removed from the ring to open the pouring outlet, the cap separates from the container. This means, for example, that the user needs to hold the cap in one hand and the container in the other. Furthermore, this inconvenience may lead to unwanted littering of the cap.

[0009] To overcome these inconveniences, it has been proposed to fasten the cover to the annular member using connecting elements. Although such closure components work satisfactorily, there is still a desire in the field to further improve such closure components. Summary of the Invention

[0010] Therefore, one object of the present invention is to provide an improved closure assembly for a container in a simple and low-cost manner, the container being filled or capable of being filled with a pourable product, or even more specifically filled or capable of being filled with a pourable food.

[0022] Preferably, but not necessarily, container 1 is filled with or can be filled with pourable products, particularly pourable foods, and more specifically, sterilized and / or aseptically treated pourable foods, such as juice, milk (e.g., milk treated with ultra-high temperature), water, wine, ketchup, sugar, salt, etc.

[0023] The following description will refer to a composite container 1, and in particular a container 1 whose body 2 is made of packaging material radiating a multi-layered structure, although this is by no means intended to limit the scope of protection as defined by the appended claims.

[0024] Specifically, the packaging material web includes at least one layer of fibrous material (e.g., a paper or cardboard layer) and at least two heat-sealable plastic material layers (e.g., polyethylene) interposed between each other. One of these two heat-sealable plastic material layers defines the inner surface of the body 2 that comes into contact with the pourable product.

[0025] Preferably, but not necessarily, the packaging material radiating material also includes a gas-barrier and light-blocking material layer, such as aluminum foil or ethylene vinyl alcohol (EVOH) film, which is specifically arranged between one of the heat-sealable plastic material layers and the fiber material layer. Preferably, but not necessarily, the packaging material radiating material also includes another heat-sealable plastic material layer inserted between the gas-barrier and light-blocking material layer and the fiber material layer.

[0026] According to a preferred non-limiting embodiment, the body 2 defines a sealed package, particularly a sealed cardboard box package, having a designated pouring opening surface area (not shown and known in itself), and the sealing component 3 is fitted to the body 2, particularly around the designated pouring opening surface area.

[0027] According to a preferred non-limiting embodiment, the sealing component 3 is applied to the body 2 before, during, or after the formation, filling, and sealing of the body 2 by molding and / or adhesive bonding and / or ultrasonic bonding.

[0028] Alternatively, the sealing component 3 may be applied to the packaging material roll before the packaging material spokes are placed inside the packaging machine or during the advance of the packaging material roll inside the packaging machine, the packaging machine being used to form, fill and seal the body 2 formed by the packaging material spokes.

[0029] For details, please refer to the following: Figure 1 The main body 2 extends along the longitudinal axis A, the first transverse axis B, and the second transverse axis C. Specifically, axis A is perpendicular to axes B and C, and axis B is perpendicular to axis C.

[0030] Preferably, but not necessarily, the extension of the main body 2 along axis A is larger than the extensions of the main body 2 along axes B and C.

[0031] Preferably, but not necessarily, the main body 2 is a cuboid shape.

[0032] According to the disclosed non-limiting embodiment, the body 2 includes a first wall portion, which is particularly transverse to axis A, and even more particularly perpendicular to axis A, from which the body 2 extends along axis A. Preferably, but not necessarily, the first wall portion defines a supporting surface of the container 1 (particularly the body 2), which can come into contact with a support (e.g., a shelf) during use, for example, when exposed at a point of sale or when stored. In particular, when arranged on a support and / or during use, during the consumption of a pourable product from the container 1, the first wall portion defines a bottom wall portion.

[0033] Preferably, but not necessarily, the body 2 also includes a plurality of sidewalls 4 which are (fixedly) connected to and extend from the first wall portion, particularly extending substantially parallel to axis A.

[0034] Preferably, but not necessarily, the body 2 also includes at least one second wall portion 5, which is opposite to the first wall portion and (fixedly) connected to the side wall 4. In other words, the side wall 4 is located between the first wall portion and the second wall portion 5. In particular, when arranged on a support and / or during use when a consumer consumes a pourable product from the container 1, the second wall portion 5 defines the top wall portion.

[0035] 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 relative to each other.

[0036] According to some non-limiting embodiments, the second wall portion 5 includes a designated pouring opening surface area.

[0037] According to a preferred non-limiting embodiment, the designated pouring opening surface area of ​​the body 2 includes a pouring hole that allows pourable product to flow out of the body 2.

[0038] According to a preferred non-limiting embodiment, the designated pouring opening surface area further includes a separation membrane sealing the pouring orifice. Specifically, the separation membrane is configured to retain the pourable product within the body 2 when intact and to be at least partially (and irreversibly) openable and / or ruptureable and / or cutable and / or puncturable to allow the pourable product to flow out of the body 2 through at least a portion of the pouring orifice. Specifically, the separation membrane is configured to allow the pourable product to flow out after it loses its integrity and to protect the pourable product from external environmental influences before it is cut and / or opened and / or ruptured and / or punctured.

[0039] Preferably, but not necessarily, the separation membrane contains a gas-barrier and light-blocking material, such as aluminum foil or ethylene vinyl alcohol (EVOH) film.

[0040] According to a preferred non-limiting embodiment, the separation membrane is defined by a portion of the packaging material radiating material, particularly by a portion of the packaging material radiating material that is different from the fibrous material layer.

[0041] According to a preferred non-limiting embodiment, the sealing component 3 includes and / or is formed of a polymeric material.

[0042] Alternatively, the enclosure component 3 may include and / or be formed of a metallic material.

[0043] Specific reference Figures 1 to 4 The closure component 3 includes at least one closure group 7, which has at least:

[0044] - Cover 8;

[0045] - Ring component 9; and

[0046] - One or more coupling elements 101, 102, which in certain cases are shown as two coupling elements 101, 102, connected to the cover 8 and the annular member 9.

[0047] Preferably, the closing group 7 is molded from a molten polymer into a single piece.

[0048] It should be noted that coupling elements 101 and 102 are connected to the cover 8 and the annular member 9 in a non-breakable and / or at least separability-resistant manner. This means that during normal use of the closure assembly 3, coupling elements 101 and 102 remain connected to the cover 8 and the annular member 9. In particular, coupling elements 101 and 102 are connected to the cover 8 and the annular member 9 to resist forces exceeding those normally exerted during normal use of the closure assembly 3. An example of such excessive force occurring is when a user attempts to arbitrarily detach coupling elements 101 and 102 from the cover 8 and / or the annular member 9 by pulling on them in opposite directions.

[0049] Specifically, connecting elements 101 and 102 connect the cover 8 and the annular member 9 to each other.

[0050] According to some preferred non-limiting embodiments, the closure assembly 3 also includes one or more breakable first coupling bridges 11 that connect the annular member 9 and the cover 8 to each other. In particular, and as explained in further detail below, the first coupling bridges 11 are configured to break during the first operation of the cover 8 (caused by the consumer).

[0051] Preferably, but not necessarily, the closure assembly 3 also includes an anti-theft ring 12 and one or more breakable (second) coupling bridges 13 connecting the anti-theft ring 12 and the annular member 9 to each other. In particular, and as explained in further detail below, the second coupling bridge 13 is configured to break during the first operation of the cover 8.

[0052] Specifically, the annular component 9 is inserted between the cover 8 and the anti-theft ring 12.

[0053] According to some non-limiting embodiments, the closure component 3 also includes a collar 14 that defines and / or limits and / or has a pouring outlet 15, which is configured to allow pourable product to flow out of the container 1.

[0054] Specifically, the collar 14 is arranged around the pouring hole.

[0055] According to some preferred non-limiting embodiments, the collar 14 extends along the longitudinal axis E. In particular, the collar 14 has an annular shape, especially an annular cross-sectional shape relative to a cross section perpendicular to the longitudinal axis E.

[0056] Specifically, the collar 14 defines and / or delineates and / or includes a flow channel for the pourable product. Even more specifically, the flow channel is inserted and / or designed to be inserted between the pour outlet 15 and the pour hole.

[0057] According to some non-limiting embodiments, the annular member 9 and / or the anti-theft ring 12 are mounted on the collar 14 and arranged around the collar 14.

[0058] Preferably, the second annular component 9 and / or the anti-theft ring 12 are coaxial with the collar 14.

[0059] Preferably, the cap 8 is connected to and / or can be connected to the collar 14 and is configured to selectively close and open the pouring outlet 15 to respectively prevent and allow the pourable product to flow out of the container 1 through the pouring outlet 15.

[0060] According to some preferred non-limiting embodiments, the cover 8 is at least in the closed position (see...). Figures 1 to 4 The cover 8 is controllable in the closed position and / or configured to close the pouring outlet 15, and in the open position, the cover 8 is open and / or configured to open the pouring outlet 15.

[0061] Preferably, but not necessarily, the cover 8 is controlled in a closed position and an open position, wherein the cover 8 is connected to and separated from the collar 14, respectively. Specifically, when the cover 8 is controlled in the closed position, it is coaxial with the collar 14 and / or the pouring outlet 15, and preferably, but not necessarily, when the cover 8 is controlled in the open position, it is transverse to the collar 14. In other words, when the cover 8 is positioned in the closed position, the cover 8 is connected to the collar 14 and covers the pouring outlet 15, while when the cover 8 is positioned in the open position, the cover 8 is separated from the collar 14 and the pouring outlet 15 is opened.

[0062] More specifically, in the disclosed specific example, the cover 8 is controlled between a closed position and an open position by a screwing action. In particular, the cover 8 includes an internally threaded portion, which is specifically disposed on the inner surface of the cover 8, and the collar 14 includes an externally threaded portion, which is specifically disposed on the outer surface of the collar 14. Preferably, the internally and externally threaded portions are configured to allow selective fastening of the cover 8 to and from the collar 14 by relative rotation between the cover 8 and the collar 14.

[0063] According to some non-limiting embodiments, the internal thread portion and / or external thread portion define the cam mechanism.

[0064] It should be noted that before the cover 8 is controlled from the closed position for the first time (first operation) to the open position, the first coupling bridge 11 connects the annular member 9 to the cover 8. During use, when the cover 8 is controlled from the closed position to the open position for the first time, the first coupling bridge 11 breaks irreversibly.

[0065] Specifically, and in an equivalent manner, the second coupling bridge 13 connects the annular member 9 and the anti-theft ring 12 to each other before the cover 8 is first controlled from the closed position to the open position, and in use, the second coupling bridge 13 irreversibly breaks when the cover 8 is first controlled from the closed position to the open position.

[0066] According to some non-limiting embodiments, the enclosure component 3 also includes a coupling base 16 that carries the collar 14. The coupling base 16 is configured to couple and / or connect and / or be coupled and / or connected to the body 2.

[0067] Preferably, but not necessarily, the coupling base 16 is configured to be fixed and / or secured to the outer surface of the container 1, particularly the outer surface of its body 2, and even more specifically, the outer surface of the second wall portion 6. In particular, the coupling base 16 is arranged within a designated area of ​​the pouring opening surface region, and even more specifically, at the designated pouring opening surface region.

[0068] Specifically, the coupling base 16 includes an opening, and the collar 14 surrounds the opening, such that in use, as the separation membrane is opened and / or cut and / or ruptured and / or punctured, a fluid connection is established between the interior of the body 2 and the pouring outlet 15 (i.e., the pouring product can flow out of the container 1).

[0069] Preferably, but not necessarily, at least a portion of the coupling base 16 has a plate-like structure.

[0070] According to some preferred non-limiting embodiments, the closure component 3, particularly the collar 14, includes an interaction device configured to interact with the annular member 9 to prevent separation of the annular member 9 from the collar 14. Specifically, the interaction device is configured to define axial movement of the annular member 9 along the longitudinal axis E.

[0071] More specifically, the interacting device includes an annular ridge 17 projecting radially from the collar 14, and is particularly composed of this annular ridge 17. Specifically, the annular ridge 17 projects radially from and away from the outer surface of the collar 14. According to some preferred, non-limiting embodiments, the annular ridge 17 has a continuous shape. Alternatively, the annular ridge 17 may have a discontinuous shape (e.g., the annular ridge 17 may be formed from multiple single components projecting from the collar 14).

[0072] According to some preferred non-limiting embodiments, the closure component 3 includes an interaction unit specifically coupled to the collar 14, configured to interact with the annular member 9 and / or the tamper-evident ring 12 to actuate the breakage of the first coupling bridge 11 and / or the second coupling bridge 13 during the initial control of the cover 8 from the closed position to the open position.

[0073] Special Reference Figure 2 The sealing assembly 3 also includes a cutting device 18 configured to rupture and / or puncture 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 rupture and / or puncture and / or cut and / or open the separation membrane.

[0074] Preferably, but not necessarily, the cutting device 18 has an annular shape and is arranged within the flow channel of the collar 14 when positioned in a stationary position, and protrudes at least partially from the flow channel when controlled in an operating position.

[0075] Specifically, the cutting device 18 is positioned in a stationary position before the cover 8 is first controlled to move from the closed position to the open position, and in an operating position after the cover 8 is first controlled to move to the open position.

[0076] Preferably, but not necessarily, the cutting device 18 is arranged in a stationary position and is in an axially elevated position relative to the operating position (relative to the longitudinal axis E).

[0110] For details, please refer to the following: Figures 2 to 4Each first curved portion 36 is connected to the first edge 27, particularly the first surface 30, at a corresponding first position 42, and each second curved portion 37 is connected to the second edge 29, particularly the second surface 30, at a corresponding second position 43.

[0111] Advantageously, each first position 42 and the corresponding second position 43 are angularly, particularly axially, offset from each other, especially about (and along) the central axis F. In particular, the first positions 42 are also angularly offset from each other, and the second positions 43 are also angularly offset from each other.

[0112] According to some preferred non-limiting embodiments, each first curved portion 36 protrudes relative to the annular member 9, and each second curved portion 37 is recessed relative to the annular member 9. In other words, each first curved portion 36 is recessed relative to the cover 8, and each second curved portion 37 protrudes relative to the cover 8.

[0113] Specifically, each first curved portion 36 bends toward the annular member 9 (pointing to the annular member 9) and each second curved portion 37 bends toward the cover 8 (pointing to the cover 8).

[0114] Advantageously, each coupling element 101, 102 is elastically deformable, in particular making the coupling elements 101, 102 function as spring elements during use and during handling and / or operation of the closing assembly 3 (in particular the closing group 7) (e.g., the cover 8 moves from the closed position to the open position).

[0115] More specifically, each first curved portion 36 includes a first mating surface 44, and each second curved portion 37 includes a second mating surface 45. Preferably, each coupling element 101, 102 is deformable to allow the corresponding first mating surface 44 to abut a corresponding first abutment portion of the first edge 27 of the cover 8 (in particular the first surface 28), while the second mating surface 45 abuts a second abutment portion of the second edge 29 of the annular member 9 (in particular the second surface 30).

[0116] In other words, each first engagement surface 44 and each second engagement surface 45 are adapted to engage the respective first adjacent portion and the respective second adjacent portion, particularly during the handling and / or operation of the closure assembly 3, and even more particularly during the handling and / or operation of the closing assembly 7. Specifically, in use, each engagement surface 44 and each engagement surface 45 engages the respective first adjacent portion and the respective second adjacent portion when the closing assembly 7 is removed from the die tool and / or when the closing assembly 7 is installed onto the collar 14.

[0117] Furthermore, during use, the coupling elements 101 and 102 may deform due to strain and / or stress and / or force acting during the handling and / or operation of the closing assembly 3 (particularly the closing group 7) (e.g., the cover 8 moving from the closed position to the open position).

[0118] In use, the consumer operates the closing component 3, particularly the closing group 7, to selectively open and close the pouring outlet 15 by controlling the cover 8 in the open or closed position.

[0119] Specifically, before the first operation of the closing assembly 3 (particularly the closing group 7), the cover 8 is in the closed position, and the first coupling bridge 11 and preferably the second coupling bridge 13 are intact (i.e., unbroken). When the cover 8 is first controlled from the closed position to the open position, the first coupling bridge 11 and preferably the second coupling bridge 13 irreversibly break.

[0120] Therefore, coupling elements 101 and 102 ensure that the cover 8 and the annular member 9 remain connected (tethered) to each other. Additionally, this means that the cover 8 is kept coupled to the collar 14 via the annular member 9. Furthermore, the tamper-evident ring 12 separates from the annular member 9, thus ensuring a tamper-evident seal.

[0121] In addition, during the initial control of the cover 8 from the rest position to the operating position, the cutting device 18 is activated, specifically to cut and / or puncture and / or open and / or rupture the separation membrane.

[0122] During operation of the closing assembly 7, particularly between the closed and open positions, the control cover 8 and coupling elements 101 and 102 elastically deform to at least partially absorb external stresses and / or forces acting on the closing assembly 3 and / or the closing assembly 7.

[0123] Furthermore, each first mating surface 44 and each second mating surface 45 may respectively abut against a corresponding first abutment portion and a corresponding second abutment portion.

[0124] Specific reference Figures 2 to 4 The internal thread portion (located in the cover 8) and the external thread portion (located in the collar 14) are configured to allow the cover 8 to be secured to the collar 14 by rotating the cover 8 relative to the collar 14 in a first rotational direction, and / or to allow the cover 8 to be released from the collar 14 by rotating the cover 8 relative to the collar 14 in a second rotational direction. The second rotational direction is opposite to the first rotational direction.

[0125] Each coupling element 101, 102 has a first end 101A, 102A connected to the cover 8 and a second end 101B, 102B connected to the annular member 9. In particular, each coupling element 101, 102 extends between the respective first end 101A, 102A and the respective second end 101B, 102B.

[0126] In each coupling element 101, 102, the first ends 101A, 102A are positioned downstream of the second ends 101B, 102B along the second rotational direction. In other words, in each coupling element 101, 102, the first ends 101A, 102A are located upstream of the second ends 101B, 102B along the first rotational direction. This configuration is particularly advantageous during the first opening of the closure assembly (where the cutting device 18 ruptures the separation membrane); in fact, it allows the cover 8 (held by the user) to drag the annular member 9 in the second direction without applying excessive stress to the coupling elements 101, 102. Therefore, even if the force required to rupture the separation membrane is high, the coupling elements(one or more) 101, 102 do not rupture.

[0127] Preferably, the first ends 101A and 102A of each coupling element 101 and 102 are connected to the first edge 27 of the cover 8. Preferably, the second ends 101B and 102B of each coupling element 101 and 102 are connected to the second edge 29 of the annular member 9.

[0128] Preferably, the closure assembly 3 includes a first coupling element 101 and a second coupling element 102 defining the one or more coupling elements 101, 102. The first coupling element 101 and the second coupling element 101 are angularly spaced from each other (along a first and / or second rotational direction). In particular, the first coupling element 101 is located upstream of the second coupling element 102 along the second rotational direction. More specifically, along the second rotational direction, a first end 101A of the first coupling element 101 is positioned upstream of a first end 102A of the second coupling element 102, and a second end 101B of the first coupling element 101 is positioned upstream of a second end 102B of the second coupling element 102. Furthermore, preferably, the first end 101A of the first coupling element 102 is positioned upstream of the second end 102B of the second coupling element 102 along the second rotational direction.

[0129] In one embodiment, the first coupling element 101 and the second coupling element 102 are located in a corner sector having a corner extension portion surrounding the central axis F of the closed assembly 3, the corner extension portion being from 20 degrees to 180 degrees (preferably from 20 degrees to 100 degrees, more preferably from 30 degrees to 80 degrees).

[0130] Preferably, the minimum distance between the first coupling element 101 and the second coupling element 102 is greater than the minimum thickness of the first coupling element 101 and / or the second coupling element 102. Specifically, the minimum thickness is considered along the circumference of the closed assembly.

[0131] The advantages of the closure component 3 according to the invention will become clear from the foregoing description.

[0132] In particular, coupling elements 101 and 102 allow damping of any strain and / or stress and / or force acting on the closed assembly 3 (especially the closed group 7).

[0133] Another advantage that has been observed is that the handling and / or operation of the closed component 3 (especially the closed group 7) is more consumer-friendly.

[0134] Furthermore, by providing more than one connecting element 101, 102, the binding force between the annular member 9 and the cover 8 can be increased.

[0135] Another advantage relates to the mounting of the closure assembly 7 onto the collar 14. To mount the closure assembly 7 onto the collar 14, the closure assembly 7 is pressed against the collar 14. Therefore, the connecting elements 101, 102 absorb at least some of the force, thereby reducing the risk of deformation of the collar 14 and / or the container 1 and / or the closure assembly 7. Specifically, each first engagement surface 44 and each second engagement surface 45 abuts the cover 8 and the annular member 9, respectively.

[0136] The applicant also observed that the specific construction of the connecting elements 101, 102 allows for the design of more durable molding tools relative to connecting elements 10 with other shapes. In particular, the specific construction and dimensions of the connecting elements 101, 102 enable the provision of molding tools having portions defining the connecting elements 101, 102, and these portions are accompanied by dimensions that provide a longer lifespan.

[0137] Furthermore, during demolding and closing of assembly 7 from the molding tool, the first mating surface 44 and the second mating surface 45 abut against the cover 8 and the annular member 9, respectively, thereby limiting deformation.

[0138] However, it is obvious that modifications can be made to the container 1 and / or the closure component 3 described herein without departing from the scope of protection defined by the appended claims.
