Abstract
A dispensing device is provided for dispensing a product that may be of viscous consistency, such as, for example, a cream or a gel. The dispensing device includes a container having a first end closed by a bottom and a second end that has an opening. A dispensing element is configured to be arranged on the product and forms a passage comprising at least one inlet orifice extending in a plane not perpendicular to an axis of the device, and an outlet orifice formed at least partly some distance from the inlet orifice. The outlet orifice extends at least partially above the inlet orifice. Rotating the dispensing element on the product causes the product to be delivered through the outlet orifice.
Claims61
A dispensing device comprising:
- a container defining a reservoir configured to contain a product, the container having a bottom, an opening, and an axis;
- a dispensing element configured to be in contact with product in the reservoir, the dispensing element defining a passage comprising at least one inlet orifice extending in a plane not perpendicular to the axis of the container and at least one outlet orifice spaced at least partially from the inlet orifice and extending at least partially above an upper edge of the inlet orifice;
- and
- a rim having an edge at least partly delimiting the outlet orifice,
- wherein the dispensing element is configured to rotate relative to the container so as to cause the product to be delivered through the outlet orifice, and
- wherein the rim is configured to allow a user to rotate the dispensing element inside the container.
