Abstract
There is described a closure for a sealed container of a pourable food product, comprising a pouring spout defining a pour opening externally closed by a cover portion, a cap fitted to the pouring spout in a removable way, an opening member interposed between the cap and the cover portion of the pouring spout and joined to the cover portion, and a driving mechanism carried by the cap to engage and pull the opening member along a direction transversal thereto upon removal of the cap from the pouring spout so as to detach the cover portion from the neck portion and free the pour opening when the closure is first unsealed by the user.
Claims48
A closure for a sealed container of a pourable food product, said closure comprising:
- a pouring spout having a neck portion to define a pour opening and a cover portion closing the pour opening on the side of said neck portion opposite to the side facing, in use, the container, the cover portion being integrally molded in one piece with the neck portion;
- and
- a cap fittable to, and removable from, the pouring spout;
- an opening member interposed between the cap and the cover portion of the pouring spout and joined to said cover portion;
- and
- driving means separate from the opening member and carried by the cap to directly engage and pull the opening member along an axis transversal thereto upon removal of said cap from the pouring spout so that the opening member detaches the cover portion from the neck portion and frees the pour opening when the closure is first unsealed by the user.
A closure for a sealed container of a pourable food product, the closure comprising:
- a pouring spout including:
- (i) a neck portion extending in an axial direction and surrounding a pour opening, and (ii) a cover portion removably attached to the neck portion and covering the pour opening;
- a cap removably attached to and fitted over the pouring spout, the cap possessing an interior surface including a circumferential surface and an axial end surface;
- an opening member fixed to the cover portion and positioned along the axial direction between the axial end surface of the cap and the cover portion, the opening member being separate from the cap so that the cap is free to rotate independently of the opening member;
- and
- a protrusion extending from the circumferential surface of the cap, the protrusion being configured to move together with the cap in such a way that, during a first removal of the cap from the pouring spout, the protrusion moves along the axial direction and first contacts the opening member to engage and pull the opening member along the axial direction upon removal of the cap from the pouring spout to detach the cover portion from the neck portion so that the pouring opening is opened when the closure is first unsealed by a user.
A closure for a sealed container of a pourable food product, said closure comprising:
- a pouring spout having a neck portion to define a pour opening and a cover portion closing the pour opening on the side of the neck portion opposite to the side facing, in use, the container, the cover portion being integrally molded in one piece with the neck portion;
- a cap fittable to, and removable from, the pouring spout;
- an opening member interposed between the cap and the cover portion of the pouring spout and joined to the cover portion;
- and
- driving means, separate from the opening member and carried by the cap, for directly contacting and pulling the opening member along an axis transversal thereto upon removal of the cap from the pouring spout, and without directly contacting the cover portion, so that movement of the opening member detaches the cover portion from the neck portion and frees the pour opening when the closure is first unsealed by the user.
A closure for a sealed container of a pourable food product, the closure comprising:
- a pouring spout having a neck portion to define a pour opening and a cover portion closing the pour opening on the side of the neck portion opposite to the side facing, in use, the container;
- a cap fittable to, and removable from, the pouring spout;
- an opening member interposed between the cap and the cover portion of the pouring spout and joined to the cover portion;
- the cover portion and the neck portion being formed in one piece at the same time so that the cover portion and the neck portion are integrally formed with one another without being separately joined together;
- and
- driving means, separate from the opening member and carried by the cap, for engaging and pulling the opening member along an axis transversal thereto upon removal of the cap from the pouring spout so that the opening member detaches the cover portion from the neck portion and frees the pour opening when the closure is first unsealed by the user.
