Dispensing system
A dispensing system for a liquid container including a cap configured to be mounted to a spout connected to a liquid container. The system includes a flexible valve positioned in the cap to be in contact with the liquid contents of the liquid container and a retaining ring connected to the cap to secure the flexible valve to the cap. The cap includes at least one channel defined by a projection configured to receive the tab of a connecting member and secure the connecting member to the cap by securing the tab in the channel under the projection.
1. A system, comprising:
a dispensing system, comprising:
a cap configured to be mounted to a spout connected to a container, the cap including a bore and a plurality of channels, wherein each of the plurality of channels is defined by a projection and a retaining projection on a free end of a stem of the projection,
a first valve positioned in the cap to be in contact with liquid contents of the container, wherein the first valve is made of a first flexible material, and
a retaining ring connected to the cap beneath the valve to secure the first valve to the cap; and
a connecting member, comprising:
an inlet member defining an inlet, wherein the inlet member comprises a plurality of tabs configured to connect to the cap, and
an outlet member defining an outlet, wherein the outlet member is configured to connect to a system supply line, and
a plurality of tabs, each of which includes a chamfer extending around an upper surface;
wherein each of the plurality of channels of the cap is configured to receive one of the plurality of tabs of the connecting member; and
wherein the connecting member is securable to the cap by inserting the connecting member into the bore of the cap and then rotating the connecting member with respect to the cap such that each of the plurality of tabs is secured in one of the plurality of channels under the projection of the one of the of the plurality of channels, wherein the chamfer of each of the plurality of tabs aids in allowing the each of the plurality of tabs to rotate past the retaining projection of the one of the plurality of channels.
2. The system of claim 1 , wherein, when the connecting member is secured to the cap, the projecting member sealingly engages the bore and urges an opening in the first valve to permit liquid in the container to pass into the inlet of the connecting member and subsequently out through the outlet.
3. The system of claim 2 , wherein the connecting member includes a seal, and the cap includes an inwardly extending flange, wherein, when the connecting member is secured to the cap, the seal engages the flange to create a seal therebetween.
4. The system of claim 1 , wherein one of the bore and the connecting member includes a bead that is configured to form a seal between the bore and the connecting member when the connecting member is secured to the cap.
5. The system of claim 1 , wherein the at least one channel is located below a top surface of the cap.
6. The system of claim 1 , wherein the bore and the first valve are integral and made of the first flexible material and are secured between the retaining ring and an inner collar of the cap.
7. The system of claim 1 further comprising a cover that covers at least a portion of the cap.
8. The system of claim 1 , wherein the first valve is secured below an inwardly extending flange of the cap.
9. The system of claim 1 , wherein the bore is defined by an inner collar of the cap.
10. The system of claim 1 , wherein the retaining ring is snapably connected to the cap to secure the valve to the cap.
11. The system of claim 1 , wherein the connecting member further includes:
a second valve positioned between the inlet and outlet such that:
the second valve allows fluid to flow from the inlet to the outlet; and
the second valve prevents fluid from flowing from the outlet to the inlet;
wherein the second valve is made of a flexible material.
12. The system of claim 11 , wherein the second valve is located within the inlet member of the connecting member.
13. The system of claim 12 , wherein the connecting member further comprises:
an outwardly extending connector flange that includes at least one tab;
wherein the second valve is located below the connector flange.
14. The system of claim 11 , wherein the inlet member includes a main body and a valve retention piece, wherein the second valve further comprises a valve flange and the valve flange is compressed between the main body and the valve retention piece.
15. The system of claim 14 , wherein:
the valve retention piece has an outer diameter at an adjacent surface to the main body;
the main body has an outer diameter at an adjacent surface to the valve retention piece; and
the valve retention piece outer diameter and the main body outer diameter are generally the same.
16. The system of claim 15 , wherein:
the valve retention piece has an inner diameter at an adjacent surface to the second valve;
the second valve has an inner diameter at an adjacent surface to the valve retention piece; and
the valve retention piece inner diameter and the second valve inner diameter are generally the same.
17. The system of claim 1 , wherein, after the connecting member is secured to the cap, the first valve resistibly or reactively urges the connecting member outwardly such that each of the plurality of tabs will be held in one of the plurality of channels by the retaining projections.
18. The system of claim 1 , wherein the plurality of tabs are equally spaced around the connecting member.
