Patent Description:
The present disclosure also relates to a container filled or fillable with a pourable product, even more particular a container filled or fillable with a pourable food product, having a closure assembly.

As is known, many liquid or pourable food products, such as fruit juice, UHT (ultra-high-temperature treated) milk, wine, tomato sauce, etc., are sold in containers, such as composite packages, bottles, cans and the like.

It is furthermore known that often such containers are provided with a closure assembly so as to selectively allow outpouring of the pourable product from the container.

A typical closure assembly comprises a collar, which is connected to the container, having a pouring outlet allowing the outpouring of the pourable product from the container and a lid configured to selectively open and close the pouring outlet and being connected to the collar when closing the pouring outlet.

It is further known that the closure assembly typically comprises a ring member coupled to and surrounding the collar. The axial movement of the ring member along the collar is typically limited by means of an annular ridge radially protruding from the collar so as to guarantee that the ring member remains coupled to the collar.

Furthermore, prior to the first removal of the lid, the ring member and the lid are connected to one another by means of coupling bridges, which rupture during the first removal of the lid from the collar. After the first removal of the lid from the collar, the ring member and the lid are detached from one another. <CIT> discloses a closure assemble comprising a lid, a ring member, a coupling element and a tamper-evidence ring.

An inconvenience is seen in that the lid is disconnected from the ring member and, thus, when removing the lid from the collar for opening the pouring outlet, the lid is detached and distinct from the container. This means e.g. that a user needs to keep the lid in one hand and the container needs to be kept in the other one. Furthermore, such inconvenience may lead to an undesired littering of the lid.

In order to overcome such inconveniences, it has been proposed to tether the lid to the ring member by means of a connection element. Even though such closure assemblies work satisfyingly well, a desire is felt in the sector to further improve such closure assemblies.

It is therefore an object of the present invention to provide in a straightforward and low-cost manner an improved closure assembly for containers, in particular filled or fillable with a pourable product, even more particular filled or fillable with a pourable food product.

Advantageously, it is a further object of the present invention to provide in a straightforward and low-cost manner an improved closure assembly for containers, which comes along with a minimal strain acting on the ring members during operation of the respective lids.

Advantageously, it is another object of the present invention to provide in a straightforward and low-cost manner a container, in particular filled or fillable with a pourable product, even more particular filled or fillable with a pourable food product, having a closure assembly, which comes along with a minimal strain acting on the ring members during operation of the respective lids.

In particular, each intermediate portion <NUM> is transversal, but not perpendicular to central axis F and/or longitudinal axis E (i.e. each intermediate portion <NUM> describes with central axis F and/or longitudinal axis E an angle ranging between <NUM>° and <NUM>° with <NUM>° and <NUM>° being excluded).

Preferentially, closure assembly <NUM> comprises an interspace <NUM> arranged between and/or delimited by lid <NUM>, in particular first rim <NUM>, even more particular first surface <NUM>, and ring member <NUM>, in particular second rim <NUM>, even more particular second surface <NUM>, and each coupling element <NUM> is positioned within interspace <NUM>.

With particular reference to <FIG>, each first curved portion <NUM> is connected to first rim <NUM>, in particular first surface <NUM>, at a respective first position <NUM> and each second curved portion <NUM> is connected to second rim <NUM>, in particular second surface <NUM>, at a respective second position <NUM>.

Advantageously, each first position <NUM> and the respective second position <NUM> are angularly, in particular also axially, displaced from one another, in particular around (and along) central axis F. In particular, also first positions <NUM> are angularly displaced from one another and also second positions <NUM> are angularly displaced from one another.

Advantageously, each connecting element <NUM> is elastically deformable, in particular so that connecting elements <NUM> act in use and during handling and/or operation of closure assembly <NUM>, in particular closing group <NUM>, (e.g. movement of lid <NUM> from the closing position to the opening position) as spring elements.

In more detail, each first curved portion <NUM> comprises a first engagement surface <NUM> and each second curved portion <NUM> comprises a second engagement surface <NUM>. Preferentially, each connecting element <NUM> is deformable such to allow for the respective first engagement surface <NUM> abutting against (a respective first abutment portion of first rim <NUM>, in particular of first surface <NUM> of) lid <NUM> and second engagement surface <NUM> to abut against (a second abutment surface portion of second rim <NUM>, in particular of second surface <NUM> of) ring member <NUM>.

In other words, each first engagement surface <NUM> and each second engagement surface <NUM> is adapted to engage respectively the respective first abutment portion and the respective second abutment portion, in particular during handling and/or operation of closure assembly <NUM>, even more particular during handling and/or operation of closing group <NUM>. In particular, in use, each engagement surface <NUM> and each engagement surface <NUM> engages respectively the respective first abutment portion and the respective second abutment portion during removal of closing group <NUM> from a mold tool and/or during mounting of closing group <NUM> onto collar <NUM>.

In addition, in use, connecting elements <NUM> may deform as a result of strain and/or stresses and/or forces acting during handling and/or operation of closure assembly <NUM>, in particular closing group <NUM>, (e.g. movement of lid <NUM> from the closing position to the opening position).

In use, a consumer operates closure assembly <NUM>, in particular closing group <NUM>, so as to selectively open and close pouring outlet <NUM> by controlling lid <NUM> in the opening configuration or the closing position.

In particular, prior to the first-time operation of closure assembly <NUM>, in particular of closing group <NUM>, lid <NUM> is in the closing position and first coupling bridges <NUM> and preferentially also second coupling bridges <NUM> are intact (i.e. not ruptured). The first time lid <NUM> is controlled from the closing position to the opening position, first coupling bridges <NUM> and preferentially also second coupling bridges <NUM> irreversibly rupture.

Thereby, connecting elements <NUM> guarantee that lid <NUM> and ring member <NUM> remain connected (tethered) to one another. Additionally, this means that lid <NUM> remains coupled to collar <NUM> by means of ring member <NUM>. Furthermore, tamper evidence ring <NUM> is detached from ring member <NUM> and allows for a tamper evidence.

Furthermore, during the first-time control of lid <NUM> from the rest position to the operative position, cutting device <NUM> is activated, in particular cutting and/or piercing and/or opening and/or rupturing the separation membrane.

During operation of closing group <NUM>, in particular control of lid <NUM>, between the closing position and the opening position, connecting elements <NUM> elastically deform thereby at least partially absorbing the external stresses and/or forces acting on closure assembly <NUM> and/or closing group <NUM>.

Moreover, each first engagement surface <NUM> and each second engagement surface <NUM> may abut against respectively the relative first abutment portion and the relative second abutment portion.

The advantages of closure assembly <NUM> according to the present invention will be clear from the foregoing description.

In particular, connecting elements <NUM> allow to damp any strain and/or stresses and/or forces acting on closure assembly <NUM>, in particular closing group <NUM>.

A further advantage has been observed in that the handling and/or operation of closure assembly <NUM>, in particular closing group <NUM>, is more consumer-friendly.

Furthermore, by providing for more than one connection element <NUM> it is possible to increase the tethering force between ring member <NUM> and lid <NUM>.

Another advantage is related to the mounting of closing group <NUM> onto collar <NUM>. In order to mount closing group <NUM> onto collar <NUM>, closing group <NUM> is forced onto collar <NUM>. Thereby, connection elements <NUM> absorb at least some of the acting forces reducing thereby the risk of a possible deformation of collar <NUM> and/or container <NUM> and/or closing group <NUM>. In particular, each first engagement surface <NUM> and each second engagement surface <NUM> abut against lid <NUM> and ring member <NUM>, respectively.

The applicant has also observed that the specific formation of connection elements <NUM> allows to design longer-lasting molding tools with respect to connection elements <NUM> having other shapes. In particular, the specific conformation and size of connection elements <NUM> allow to provide for molding tools having portions defining connection elements <NUM> and which portions come along with dimensions which provide for a longer lifetime.

Furthermore, during unmolding of closing group <NUM> from the molding tool, first engagement surface <NUM> and second engagement surface <NUM> abut against lid <NUM> and ring member <NUM>, respectively, limiting thereby the deformation.
