Abstract

Device to contain and dispense fluid, including: container including neck, connector with ring cap element; deformable bag, for housing inside a container cavity and including neck having opening to access bag cavity, and bag flange extending transversally to the bag neck; manual pump at least partially in the bag neck; ring cap element connected to container neck for connecting pump and bag to container neck; an annular support element for resting on a container neck free edge, annular support element including: seat including rest wall for bag neck flange, ring cap element, when connected to container neck, binding annular support element and at least one flange portion and annular element to container neck; and connector for cooperating with connection counter-part in ring cap element. Ring cap element includes connection counter-part for cooperating with container neck connector for removably connecting ring cap and container neck.

First claim

The invention claimed is:

1. A device to contain and dispense fluid substances, comprising:
a container comprising a neck, having an opening to access a cavity of the container, and having first connection means for connection with a ring cap element;
a bag made from a deformable material, suitable to be housed inside said cavity of the container and comprising a neck having an opening to access a cavity of the bag, said bag being provided with a flange extending transverse to said neck of the bag;
a pump which can be operated manually to draw a fluid substance from the bag and feed the fluid substance outside through a dispensing stem of the pump, said pump being housed at least partially in said neck of the bag;
said ring cap element connected to said neck of the container being suitable to connect said pump and said bag to the neck of the container;
an annular support element suitable to be arranged resting on a free edge of the neck of the container, said annular support element comprising:
a seat comprising at least one rest wall for at least one portion of said flange of the neck of the bag, said ring cap element, when connected to the neck of the container, binding together said annular support element and said at least one portion of said flange, as well as said annular support element to the neck of the container; and
second connection means suitable to cooperate with first connection counter-means provided in said ring cap element, to steadily bind together said annular support element and said ring cap element even when said ring cap element is disengaged from the neck of the container, so that, when the fluid substance contained in the bag is drawn and the ring cap element is disengaged from the neck of the container, if said ring cap element is removed, at least said bag, said pump and said annular support element remain steadily bound to said ring cap element;

wherein said ring cap element comprises a second connection counter-means suitable to cooperate directly with said first connection means of the neck of the container to connect removably together said ring cap element and said neck of the container.

2. A device according to claim 1 , wherein the annular support element comprises a centering and positioning portion, projecting downward from the at least one rest wall and suitable to engage with an upper inner or outer portion of the neck of the container.

3. A device according to claim 2 , wherein the centering and positioning portion has a limited height H 1 and the neck of the container has a height H 2 , the limited height H 1 being equal to or less than 20% of the height H 2 .

4. A device according to claim 2 , wherein the centering and positioning portion has a limited height H 1 equal to or less than 10% of a height of the neck of the container.

5. A device according to claim 2 , wherein the centering and positioning portion has a limited height H 1 equal to or less than 5% of a height of the neck of the container.

6. A device according to claim 1 , wherein a maximum diameter of the annular support element is equal to or less than a maximum diameter of the neck of the container.

7. A device according to claim 1 , wherein said second connection means comprises at least one tooth projecting from a free outer surface of the annular support element.

8. A device according to claim 7 , wherein said second connection means of said annular support element comprises only one continuous circular tooth concentric to said annular support element, or a plurality of teeth arranged along a same circumference concentric to said annular support element.

9. A device according to claim 7 , wherein said second connection means are provided on an outer surface of the annular support element.

10. A device according to claim 9 , wherein the annular support element has at least one contact surface suitable to come into contact with the neck of the container, said at least one contact surface having the at least one passage channel.

11. A device according to claim 1 , further comprising at least one passage channel for air flow between an outer side of the container and a gap existing between an inner surface of the cavity of the container and an outer surface of the bag housed in said cavity.

12. A device according to claim 1 , wherein the ring cap element is a single ring cap element.

13. A device according to claim 1 , wherein the annular support element comprises:
at least one substantially flat wall, having a lower surface suitable to rest on a free upper edge of the neck of the container and an upper surface on which at least one portion of the flange of the bag rests,
wherein a width of said lower surface is substantially the same as a width of said free upper edge of the neck of the container.

14. A device according to claim 1 , wherein the annular support element comprises:
at least one substantially flat wall, with a substantially horizontal development, having a lower surface suitable to rest on a free upper edge of the neck of the container and an upper surface on which at least one portion of the flange of the bag rests,
wherein a vertical wall develops from said at least one substantially flat wall perpendicularly upwards and the second connection means is suitable to cooperate with the first connection counter-means provided in said ring cap element to steadily bind together said annular support element and said ring cap element, wherein the second connection means projects from a face turned toward the outside of said vertical wall.

15. A device according to claim 1 , wherein an overall height of the annular support element is lower than at least 50% of an overall height of the neck of the container.

16. A device according to claim 1 , wherein an overall height of the annular support element is lower than 30% of a height of the neck of the container.

17. A device according to claim 1 , wherein an overall height of the annular support element is lower than 20% of an overall height of the neck of the container.
