One-piece hinged closure for equipping a container
View Patent ↗A one-piece closure can mount on a container having an aperture. The one-piece closure includes a base portion that inwardly defines an opening centered about a base portion longitudinal axis and that is intended to be mounted on the container neck. The one-piece closure includes a hinged cap that is linked to the base portion by an outside hinge member. The hinge member has two opposite ends that are respectively connected to the base portion and the cap, the cap being movable between a closed position in which it closes the aperture of the base portion and an open position in which the aperture is left clear. The two opposite ends of the hinge member are aligned along an axis that is inclined with respect to the base portion longitudinal axis when the cap is in the closed position.
1. A one-piece closure for a container having an aperture, comprising:
a base portion having a base portion longitudinal axis, the base portion longitudinal axis is perpendicular to a horizontal plane, the base portion inwardly defines an opening centred about the base portion longitudinal axis, and the base portion is intended to be mounted on a neck of the container,
a hinged cap that is linked to the base portion by an outside hinge member, the outside hinge member having a first end connected to the base portion and a second end opposite the first end and connected to the cap, the cap being movable between (i) a closed position in which the cap closes the opening of the base portion and an open position in which the opening is left clear; and
the outside hinge member has a continuous slope relative to the horizontal plane and the base portion longitudinal axis when the cap is in the closed position.
2. The closure of claim 1 , wherein the cap is centred about a cap axis that coincides with the base portion longitudinal axis in the closed position, and that does not intersect with the base portion longitudinal axis in the open position.
3. The closure of claim 1 , wherein the hinge member has an elongated shape.
4. The closure of claim 1 , wherein the hinge member has an overall shape of a strip.
5. A container, comprising:
a neck having an aperture, and
a one-piece closure mounted on the neck for closing the aperture,
the closure comprising (i) a base portion having a base portion longitudinal axis, the base portion longitudinal axis is perpendicular to a horizontal plane, the base portion inwardly defines an opening centred about the base portion longitudinal axis, and the base portion is mounted on the neck of the container, (ii) a hinged cap that is linked to the base portion by an outside hinge member, the hinge member having a first end connected to the base portion and a second end opposite the first end and connected to the cap, the cap being movable between (i) a closed position in which the cap closes the opening of the base portion and an open position in which the opening is left clear, and the outside hinge member has a continuous slope relative to the horizontal plane when the cap is in the closed position.
