Abstract
A pouring spout for an opening in a container includes a pouring spout housing with at least one opening and a hollow cylinder member which is displaceable in an axial direction relative to the pouring spout housing between a closing position in which the cylinder member closes the opening in the pouring spout housing and a pouring position in which the opening is left clear.
Claims18
A pouring spout with refill prevention device for an opening in a container, comprising:
- a pouring spout housing having a hollow cylindrical part with at least one opening;
- a hollow cylinder member which is displaceable in an axial direction relative to the hollow cylindrical part between a closing position in which the hollow cylinder member closes the at least one opening in the hollow cylindrical part and a pouring position in which the at least one opening in the hollow cylindrical part is left clear;
- and
- a movable weight positioned in the pouring spout housing displacing the hollow cylinder member between the closing position and the pouring position,
- wherein the inside of the pouring spout housing having a contact surface for the movable weight, with the contact surface diverging toward the hollow cylindrical part, and
- wherein the diverging contact surface and the movable weight maintain the hollow cylinder member in the closing position until the pouring spout housing is tilted to an angle greater than or equal to a slope of the contact surface.

A pouring spout with refill prevention device for an opening in a container, comprising:
- a pouring spout housing having a hollow cylindrical part, the hollow cylindrical part provided with a plurality of openings defined in the periphery of the hollow cylindrical part;
- a hollow cylinder member which is displaceable in an axial direction relative to the hollow cylindrical part between a closing position in which the hollow cylinder member closes the openings in the hollow cylindrical part and a pouring position in which the openings in the hollow cylindrical part are left clear, the hollow cylinder member having guide ribs on the outside of the hollow cylinder member guiding the displacement of the hollow cylinder member relative to the hollow cylindrical part;
- and
- a movable weight positioned in the pouring spout housing displacing the hollow cylinder member between the closing position and the pouring position,
- wherein the inside of the pouring spout housing having a contact surface for the movable weight, with the contact surface diverging toward the hollow cylindrical part, and
- wherein the diverging contact surface and the movable weight maintain the hollow cylinder member in the closing position until the pouring spout housing is tilted to an angle greater than or equal to a slope of the contact surface.
