Abstract

A device to contain and deliver fluid substances includes: a container including a housing suitable for containing a substance to be delivered; a feed element for feeding the substance outside the container, including a piston portion inserted inside the housing of the container, and a conveyance portion connected to the piston portion; a dispenser cap connected to the conveyance portion and such as to push the piston portion into the housing of the container and to deliver the substance; at least one element to guide the movement of the piston portion into the housing of the container; wherein the piston portion of the feed element is operated only manually by acting onto the dispensing cap.

First claim

The invention claimed is:

1. A device to contain and deliver fluid substances, comprising:
a container comprising a housing suitable to contain a substance to be delivered, said housing having a bottom wall and at least one side wall delimiting an opening;
a feed element to feed said substance outside the container, having a piston portion suitable to be inserted inside said housing of the container and to sealingly slide against said at least one side wall so as to exert pressure on said substance contained in said housing of the container, and a conveyance portion connected to said piston portion having at least one channel to convey said substance outside said housing;
a dispenser cap comprising a connection element for said channel of the feed element, with at least one pipe for said dispenser cap, one dispenser mouth for said substance connected to said pipe, and one actuation portion suitable to be hand-operated to manually handle said feed element so as to push said piston portion into said housing of the container and deliver the substance;
at least one guide element to guide the handling of said piston portion into said housing of the container, said guide element comprising a rod extending from said bottom wall of the housing of the container and suitable to be inserted in said channel of the conveyance portion of the feed element;
wherein said rod comprises at least one duct for flowing there through the substance to be delivered;
wherein said piston portion of said feed element is handled only manually by acting on said dispenser cap.

2. The device according to claim 1 , consisting of only three components: the container, the feed element and the dispenser cap, said at least one guide element being integral with said container.

3. The device according to claim 1 , wherein the rod is arranged coaxially with respect to the housing of the container.

4. The device according to claim 1 , wherein the container comprises an outer side wall, separate and distinct from a side wall of the housing containing the substance to be delivered.

5. The device according to claim 1 , characterised in that wherein the housing containing the substance and the piston portion of the feed element are shaped to allow all said substance to be delivered by manually actuating said piston portion a single time.

6. The device according to claim 1 , wherein the housing containing the substance to be delivered has a volume of less than 15 ml.

7. The device according to claim 1 , wherein the housing of the container has a cylindrical shape and the piston portion of the feed element is disc-shaped to be sealingly introduced against the side wall of said housing of the container and to move coaxially relative to said housing, and in that the conveyance portion centrally branches off from said piston portion and has at least the channel for delivering the substance.

8. The device according to claim 1 , wherein the dispenser cap comprises closure means for an end mouth of said conveyance portion of the feed element, suitable to let said end mouth open/closed, and said dispenser cap is rotatingly connected to the feed element between an opening position, wherein a pipe of the dispenser cap is in communication with said conveyance portion of the feed element, and a closing position, wherein said end mouth of the conveyance portion is closed by said closure means of the dispenser cap.

9. The device according to claim 1 , wherein the dispenser cap comprises an upper wall and at least one side wall, the container comprising an outer side wall, and said side wall of the dispenser cap and said outer wall of the container are shaped in such a way that a portion of said side wall of the dispenser cap covers and slides along at least one portion of the outer wall of the container.

10. The device according to claim 9 , wherein the dispenser cap is provided with engagement means in the side wall of the dispensing cap, the container being provided with engagement counter-means suitable to cooperate with said engagement means of the dispenser cap, so as to prevent said dispenser cap from being accidentally removed after said dispenser cap has been associated to the container.

11. The device according to claim 1 , wherein the feed element is suitable to feed the substance outside the container by a single handling of the piston portion from a first, raised starting position, when the container is completely filled with the substance, to a second, lowered ending position, when the container is substantially empty.

12. The device according to claim 1 , wherein the guide element is suitable to allow said piston portion only to translate axially relative to said housing of said container, and said connection element connecting said dispenser cap to said feed element is suitable to allow said dispenser cap to translate axially relative to said housing of the container along with said piston portion and also to rotate around a central axis of said piston portion.

13. The device according to claim 1 , wherein the dispenser cap comprises at least one partitioning element splitting up the delivery of the substance, comprising a lower edge forming at least two consecutive steps suitable to come in contact with at least one end-of-stroke counter element provided in the container.

14. The device according to claim 1 , comprising at least a further guide element to guide the handling of the piston portion in the housing of the container, suitable for interacting with the inner surface or the outer surface of the side wall of the container.

15. The device according to claim 1 , comprising at least a block element for blocking the handling of the dispenser cap and an undesired delivery of the fluid substance.
