Claim 19:
20. An assembly for packaging and dispensing a fluid product, comprising:
a container configured to contain the product; and
a dispensing device for dispensing the product,
wherein the dispensing device comprises:
a dispensing end through which the product is to be dispensed;
an attachment end attached to the container containing the product; and
a dispensing valve provided between the attachment end and the dispensing end and formed by a flexible member and a rigid member, the dispensing valve being configured to be actuatable between an open position in which a dispensing channel is formed between the flexible member and the rigid member to allow the product to flow toward the dispensing end, and a closed position in which the dispensing channel is closed, and
wherein the dispensing valve comprises a first valve portion and a second valve portion formed by the flexible member and a first valve seat and a second valve seat formed by the rigid member, the second valve portion being located closer to the dispensing end than the first valve portion, the dispensing valve being configured such that the first valve portion directly rests on the first valve seat and the second valve portion directly rests on the second valve seat when the dispensing valve is in the closed position and that a greater biasing force is applied by the first valve portion onto the first valve seat than a biasing force applied by the second valve portion onto the second valve seat when the dispensing valve is in the closed position, and
wherein the flexible member is provided coaxially around the rigid member, the flexible member including an axial extension extending axially farther from the attachment end than a farthest tip of the rigid member, and a radial extension extending radially inwardly from the axial extension to define a dispensing opening at the dispensing end, the dispensing opening being situated axially farther from the attachment end than the farthest tip of the rigid member,
wherein the dispensing channel and the dispensing opening are connected by a guide channel defined between the radial extension and the farthest tip of the rigid member, the guide channel being in fluid communication with the dispensing opening irrespective of whether the dispensing valve is in the open position or in the closed position.
