Abstract
Description
Technical Field
[0001] The present invention relates to a closure assembly for a container, in particular a container filled or fillable with a pourable product, more particularly a container filled or fillable with a pourable food product.
[0002] The invention also relates to a container filled or fillable with a pourable product, in particular a container filled or fillable with a pourable food product having a closure assembly. Background Art
[0003] As is known to all, many liquid or pourable foods, such as juice, UHT (ultra-high temperature treated) milk, wine, ketchup, etc., are sold in containers, such as composite packages, bottles, cans, etc.
[0004] Furthermore, as is known, these containers are usually provided with closure means for selectively pouring the pourable product from the container.
[0005] A typical closure assembly includes a collar connected to a container, the collar having a pouring spout that allows a pourable product to be poured from the container; and a cap configured to selectively open and close the pouring spout and connected to the collar when the pouring spout is closed.
[0006] As is known, the closure assembly generally comprises an annular component coupled to and surrounding the collar. The axial movement of the annular component along the collar is generally limited by an annular ridge protruding radially from the collar to ensure that the annular component remains coupled to the collar.
[0007] Furthermore, before the cover is removed for the first time, the ring part and the cover are connected to each other by means of a coupling bridge, which is broken when the cover is removed from the collar for the first time. After the cover is removed from the collar for the first time, the ring part and the cover are separated from each other.
[0008] The inconvenience of the lid being detached from the ring is that, when the lid is removed from the collar to open the pouring spout, the lid is removed from the container and separated from the container. This means that the user needs to hold the lid with one hand and the container with the other. Furthermore, this inconvenience may lead to the lid being discarded carelessly.
[0009] In order to overcome this inconvenience, it has been proposed to fasten the cap to the annular member by means of a connecting element. Although the effect of such a cap assembly is satisfactory, the industry still hopes to further improve such a cap assembly. In particular, the fastened cap may have such an inconvenience that once the cap is opened, the cap may interfere with the pouring outlet when pouring the liquid product out of the container. Summary of the invention
[0010] It is therefore an object of the present invention to provide an improved closure assembly for containers, in particular containers filled or fillable with pourable products, more particularly containers filled or fillable with pourable food products, in a straightforward and cost-effective manner.
[0011] Advantageously, it is another object of the present invention to provide an improved container closure assembly in a straightforward and cost-effective manner which assembly produces minimal strain on the annular member during operation with the lid.
[0012] Advantageously, another object of the present invention is to provide in a straightforward and low-cost manner a container, in particular a container filled or fillable with a pourable product, in particular a container filled or fillable with a pourable food product, having a closure assembly which produces minimal strain on the annular member during operation of the corresponding lid.

[0048] It should be noted that the coupling elements 101, 102 are connected to the lid 8 and the annular part 9 in a manner that is unbreakable and / or at least resistant to separation. This means that during normal use of the closure assembly 3, the coupling elements 101, 102 remain connected to the lid 8 and the annular part 9. In particular, the coupling elements 101, 102 are connected to the lid 8 and the annular part 9 so as to resist forces that exceed the forces that are usually applied during normal use of the closure assembly 3. An example of such excessive forces is when a user intentionally detaches the coupling elements 101, 102 from the lid 8 and / or the annular part 9 by pulling the lid 8 and the annular part 9 in different directions from each other.

[0112] Furthermore, when in use, the coupling elements 101, 102 may deform due to strains and / or stresses and / or forces during handling and / or operation of the closure assembly 3, in particular the closure group 7 (e.g., movement of the lid 8 from a closed position to an open position).
[0113] In use, a consumer operates the closure assembly 3, in particular the closure group 7, to selectively open and close the pouring spout 15 by controlling the lid 8 to be in an open position or a closed position.
[0114] In particular, before the first operation of the closure assembly 3, in particular the closure group 7, the lid 8 is in the closed position, and the first coupling bridge 11 and the preferred second coupling bridge 13 are intact (i.e. not broken). When the lid 8 is first controlled from the closed position to the open position, the first coupling bridge 11 and the preferred second coupling bridge 13 will be irreversibly broken.
[0115] Thus, the coupling elements 101, 102 ensure that the cap 8 and the annular part 9 remain connected (fastened) to each other. Furthermore, this also means that the cap 8 remains coupled to the collar 14 via the annular part 9. Furthermore, the tamper-proof ring 12 is disengaged from the annular part 9, thereby providing tamper-proof evidence.
[0116] Furthermore, when the cover 8 is first moved from the rest position into the operating position, the cutting device 18 is activated, in particular to cut and / or pierce and / or open and / or rupture the separation membrane.
[0117] During operation of the closure group 7 , in particular during control of the lid 8 from the closed position to the open position, the coupling elements 101 , 102 are elastically deformed, thereby at least partially absorbing external stresses and / or forces acting on the closure assembly 3 and / or the closure group 7 .
[0118] Furthermore, each first engaging surface 44 and each second engaging surface 45 may abut against a corresponding first abutting portion and a corresponding second abutting portion, respectively.
[0119] Special References Figures 2 to 4, the internal threaded portion (disposed in the cap 8) and the external threaded portion (disposed in the collar 14) are configured to fix the cap 8 to the collar 14 by rotating the cap 8 relative to the collar 14 in a first rotational direction, and / or to release the cap 8 from the collar 14 by rotating the cap 8 relative to the collar 14 in a second rotational direction. The second rotational direction is opposite to the first rotational direction.
[0120] 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 is elongated between the respective first end 101A, 102A and the respective second end 101B, 102B.
[0121] In each coupling element 101, 102, the first end 101A, 102A is located downstream of the second end 101B, 102B in the second rotational direction. In other words, in each coupling element 101, 102, the first end 101A, 102A is located upstream of the second end 101B, 102B in the first rotational direction. This configuration is particularly advantageous during the first opening of the closure assembly (wherein the separation membrane is broken by the cutting device 18); in fact, it allows the lid 8 (grasped by the user) to pull the annular part 9 in the second direction without excessive stress on the coupling element 101, 102. Therefore, even if the force required to break the separation membrane is large, the coupling element 101, 102 will not break.
[0122] Preferably, the first end 101A, 102A of each coupling element 101, 102 is connected to the first edge 27 of the cover 8. Preferably, the second end 101B, 102B of each coupling element 101, 102 is connected to the second edge 29 of the annular component 9.
[0123] Preferably, the closure assembly 3 comprises a first coupling element 101 and a second coupling element 102, which define the one or more coupling elements 101, 102. The first coupling element 101 and the second coupling element 101 are angularly distant from each other (along the first and / or second rotational direction). In particular, along the second rotational direction, the first coupling element 101 is located upstream of the second coupling element 102. More specifically, along the second rotational direction, the first end 101A of the first coupling element 101 is located upstream of the first end 102A of the second coupling element 102, and the second end 101B of the first coupling element 101 is located upstream of the second end 102B of the second coupling element 102. Furthermore, preferably, along the second rotational direction, the first end 101A of the first coupling element 102 is located upstream of the second end 102B of the second coupling element 102.
[0124] In an embodiment, the first coupling element 101 and the second coupling element 102 are located within an angular sector, which extends around the central axis F of the closed component 3 in an angular range of 20 degrees to 180 degrees (preferably 20 degrees to 100 degrees, more preferably 20 degrees to 90 degrees, and even more preferably 30 degrees to 80 degrees).
[0125] 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. In particular, the minimum thickness is considered along the circumferential direction of the closed component.
[0126] The first and second coupling elements 101, 102 are structured so as to have a hinge axis L, and the cover 8 can rotate relative to the annular member around the hinge axis L. In particular, when the cover 8 moves from the closed state to the open state, the cover 8 rotates around the hinge axis L, and vice versa. It should be noted that the cover 8 can move by either rotational movement around the hinge axis L or displacement movement along the longitudinal axis E when moving from the closed state to the open state, and vice versa.
[0127] When the lid 8 is in the open state, the lid 8 can also be rotated around the torsion axis H. The torsion axis H is approximately orthogonal to the hinge axis L. Preferably, the torsion axis H is also approximately orthogonal to the longitudinal axis E. By rotating around the torsion axis H, the lid 8 can be in a temporary locking position, in which the first edge 27 of the lid 8 at least partially abuts against the external threaded portion 140 of the collar. The temporary locking position is a stable position.
[0128] When the cover 8 is arranged in the temporary locking position, the cover 8 is located on one side of the collar 14. Fig. 9 ), the pouring outlet is completely free, i.e. the lid 8 is not therein at all. Like this, the lid 8 just can not influence the outflow of the product.
[0129] In particular, the closure assembly is designed so that the user can perform the following actions in sequence starting from the closed state: 1) rotating the cover 8 relative to the collar 14 about the longitudinal axis E, thereby unscrewing the cover 8 from the collar 14 and moving the cover 8 from the closed state to the open state, 2) In the open state, the lid 8 is rotated about the hinge axis L relative to the collar 14 and simultaneously (slightly) moved along the longitudinal axis E so that the lid 8 is partially moved out of the pouring outlet ( Figure 5 and Figure 6 middle position shown), 3) Still in the open state, the lid 8 is rotated relative to the collar 14 about the torsion axis H to move the lid 8 into a temporary locking position (eg Figure 7 , Figure 8 and Fig. 9shown), 4) Pour the product out of the container through the pouring outlet 15.
[0130] In the closed state, the length of the first coupling element 101 is greater than the distance between the first end 101A of the first coupling element 101 and the second end 101B of the first coupling element 101, and the length of the second coupling element 102 is greater than the distance between the first end 102A of the second coupling element 102 and the second end 102B of the second coupling element 102. Such lengths of the first and second coupling elements 101, 102 combined with appropriate selection of the material and elasticity of the first and second coupling elements 101, 102 enable the cover 8 to be twisted about the torsion axis H and arranged in a temporary locking position.
[0131] In the open state, before the cover 8 is rotated about the torsion axis H, the first coupling element 101, the second coupling element 102, the first edge 27 of the cover 8 and the second edge 29 of the annular member 9 define a hole. In particular, the hole has a bottom edge defined by the second edge 29, an upper edge defined by the first edge 27, and a pair of side edges defined by the first and second coupling elements 101, 102. The torsion axis H passes through the hole. For example, in Figure 5 The hole can be seen in the
[0132] Preferably, in the temporary locking position of the cover 8, the first edge 27 of the cover 8 is at least partially arranged below the external threaded portion 140 along the longitudinal axis E (i.e., the first edge 27 of the cover 8 is closer to the coupling base 16 than at least a portion of the external threaded portion 140). In particular, the elasticity of the first and second coupling elements 101 and 102 that have been twisted around the torsion axis H pushes the cover 8 away from the coupling base 16, while the external threaded portion 140 provides an obstacle, so that the first edge 27 abuts against the external threaded portion 140 and keeps the cover 8 in the temporary locking position.
[0133] It should be noted that, since the cap 8 can rotate together with the ring 9 around the longitudinal axis E, and since the external threaded portion 140 extends 360 degrees around the longitudinal axis E, the cap 8 can be set in all temporary locking positions around the longitudinal axis E. In other words, the cap 8 can be set in a plurality of temporary locking positions around the longitudinal axis E.
[0134] Preferably, in the temporary locking position of the lid 8, the lid 8 lies on a plane inclined at a certain angle relative to a plane orthogonal to said longitudinal axis E. Preferably, said angle is between 5 and 60 degrees, even more preferably between 10 and 30 degrees. Thus, the lid axis G (around which the first edge 27 extends in a circle) is inclined relative to the longitudinal axis E at said angle.
[0135] Preferably, in the temporary locking position of the cover 8, the inner surface of the top wall 25 of the cover 8 faces the coupling base 16. When the cover 8 is in the closed state, the inner surface of the top wall 25 faces the pouring outlet 15.
[0136] The present disclosure also provides a method for opening a closure assembly 3 applied to a container 1 filled with a pourable product. The closure assembly 3 is according to one or more aspects of the present disclosure. The method comprises the following steps: - rotating the cover 8 relative to the collar 14 about the longitudinal axis E in order to remove the cover 8 from the collar 14 The closed state on the ring 14 moves to an open state disengaged from the collar 14; - while rotating the cover 8 about the longitudinal axis E, the cutting device 18 is moved from the stationary position to the The stop position is controlled to the working position; When the cover 8 is in the open state, the cover 8 is further rotated about the torsion axis H to bring the cover 8 into a temporary locking position, in which the first edge 27 of the cover 8 at least partially abuts against the external threaded portion 140 of the collar 14 .
[0137] The advantages of the closure assembly 3 according to the present invention will be apparent from the above description.
[0138] Firstly, the lid 8 can be arranged in a temporary locked position, ensuring that the lid does not hinder the outflow of the product from the pouring outlet.
[0139] In particular, the coupling elements 101 , 102 may reduce any strains and / or stresses and / or forces acting on the closure assembly 3 , in particular the closure group 7 .
[0140] Another advantage that has been observed is that the handling and / or operation of the closure assembly 3, in particular the closure group 7, is more consumer-friendly.
[0141] Furthermore, by providing more than one connecting element 101 , 102 , the tethering force between the annular member 9 and the cover 8 may be increased.
[0142] Another advantage is related to mounting the closure group 7 on the collar 14. To mount the closure group 7 on the collar 14, the closure group 7 is pressed onto the collar 14. Thus, the connecting elements 101, 102 absorb at least part of the forces, thereby reducing the risk of possible deformation of the collar 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 come into contact with the lid 8 and the annular part 9, respectively.
[0143] The applicant has also noted that the special formation of the connecting elements 101, 102 allows the design of a molding tool with a longer life compared to connecting elements 10 with other shapes. In particular, the special shape and size of the connecting elements 101, 102 allow the provision of a molding tool with portions defining the connecting elements 101, 102, and these portions have a size that provides an extended service life.
[0144] Furthermore, during demoulding of the closing group 7 from the molding tool, the first and second engagement surfaces 44, 45 come into contact with the lid 8 and the annular part 9, respectively, limiting deformation.
[0145] Obviously, the container 1 and / or the closure assembly 3 described herein may be modified without departing from the scope of protection defined by the accompanying claims.
