Abstract

A lid-spout assembly including at least a spout having a pouring outlet, a lid configured to selectively close and open the pouring outlet, a tethering element fixed to the lid and the spout and a tamper evidence element rupturably fixed to one of the lid and the spout and fixedly connected to the other one of the lid and the spout.

First claim

The invention claimed is:

1 . A lid-spout assembly for a package having a main body comprising a designated pour opening and being filled with a pourable product;
the lid-spout assembly comprises at least: a spout having a pouring outlet; a lid configured to selectively close and open the pouring outlet; and a tethering element fixed to the lid and the spout; wherein the spout comprises at least: a base frame configured to couple the spout to the main body about the designated pour opening; a collar carrying the pouring outlet and protruding from the base frame; wherein the lid is controllable between at least:
a closed position in which the lid covers the pouring outlet; and
an open position in which the lid is detached from the pouring outlet;
wherein the lid-spout assembly also comprises an annular coupling membrane rupturably fixing the lid and the collar to one another prior to the first time the lid is controlled from the closed position to the open position; wherein the lid-spout assembly further comprises a tamper evidence element; wherein the tamper evidence element extends between a first end rupturably fixed directly to one of the lid and the collar and a second end directly fixed to the other one of the lid and the collar along a central extension axis, and wherein a curvature of the tamper evidence element extends from the first end to the second end; and the spout, the lid, the tethering element and the tamper evidence element are formed in a single piece so that the lid-spout assembly is in an initial configuration in which the lid is in the closed position.

2 . The lid-spout assembly according to claim 1 , wherein the collar comprises an inner surface delimiting a flow channel for the pourable product and an outer surface opposite to the inner surface;
wherein the tamper evidence element is rupturably fixed to the outer surface.

3 . The lid-spout assembly according to claim 1 , wherein the lid comprises a gripping element;
wherein the tamper evidence element is rupturably fixed or fixed to the gripping element.

4 . The lid-spout assembly according to claim 3 , wherein the lid comprises at least a main portion configured to at least partially protrude into the flow channel;
wherein the gripping element protrudes from the main portion.

5 . The lid-spout assembly according to claim 4 , wherein the main portion comprises at least a central section at least partially protruding into the flow channel and a peripheral section connected to and surrounding the central section and configured to engage and/or engaging a rim of the collar delimiting the pouring outlet.

6 . The lid-spout assembly according to claim 1 , wherein the tamper evidence element comprises a first end and a second end;
wherein the first end is rupturably fixed to one of the lid and the spout and the second end is fixedly connected to the other one of the lid and the spout.

7 . The lid-spout assembly according to claim 6 ,
wherein the tamper evidence element is designed such that, in use, the first time the lid is controlled from the closed position to the open position the first end irreversibly ruptures.

8 . The lid-spout assembly according to claim 6 , wherein the tamper evidence element has a first cross-sectional profile at the first end and a second cross-sectional profile at the second end;
wherein the first cross-sectional profile is smaller than the second cross-sectional profile.

9 . The lid-spout assembly according to claim 1 , wherein the tamper evidence element comprises a first contact surface rupturably fixed to one of the lid and the spout and a second contact surface fixed to the other one of the lid and the spout;
wherein the first contact surface is smaller than the second contact surface.

10 . The lid-spout assembly according to claim 1 , wherein a cross-section of the tamper evidence element has an oval or circular shape.

11 . The lid-spout assembly according to claim 1 , wherein the tamper-evidence element is rupturably fixed to the collar.

12 . A package comprising a main body filled with a pourable product and at least one lid-spout assembly according to claim 1 and coupled to the main body.

13 . The package according to claim 12 , wherein the package is designed for the consumption on-the-go.

14 . The package according to claim 12 , wherein the main body is formed from a multilayer composite packaging material.
