Abstract

A valve for injecting a fluid into a bowl has a vent with an inlet and a flexible diaphragm for covering the discharge opening of the vent. The diaphragm is connected to a vessel body of a bowl, and the vent is connected to a stand of a bowl. The diaphragm has a closing area for closing the discharge opening and a connecting area for connecting the diaphragm with the vessel body spaced to the vent. At least one window is provided between the closing area and the connecting area.

First claim

The invention claimed is:

1. Valve comprising
a vent for injecting a fluid, wherein the vent comprises an inlet connected to a discharge opening via a discharge channel, and
a flexible diaphragm for covering the discharge opening of the vent,
wherein:
(i) the diaphragm is separated from the vent,
(ii) the diaphragm is adapted to be connected to a first part, which first part is a vessel body of a bowl,
(iii) the vent is adapted to be connected to a second part, which second part is a stand of a bowl,
(iv) the diaphragm comprises a closing area for closing the discharge opening and a connecting area configured for connecting the diaphragm with the first part,
(v) the connecting area is radially spaced to the vent such that it does not come into contact with the vent when discharge opening is closed by the closing area, and
(vi) at least one window is provided between the closing area and the connecting area, and
(v) the connecting area is connected with the closing area via bridges, wherein each window is bordered by the closing area, the connecting area and two bridges,
and wherein the valve is further configured such that
(vii) when the discharge opening is closed by the closing area, the closing area is located on a plane higher than the bridge, and/or
(viii) when the discharge opening is closed by the closing area, the bridge slopes downward radially from the closing area to the connecting area, and/or
(ix) the connecting area has a thickness defined by a distance between a top and a bottom surface thereof, wherein said thickness is the same as that of the bridges or the window.

2. Valve according to claim 1 , wherein the connecting area of the diaphragm is arranged at least partially on a level below the closing area in the designated use position for pressing the closing area onto the discharge opening of the vent.

3. Valve according to claim 1 , wherein at least a part of the diaphragm arranged above the discharge channel, is positioned on a different level than the vent.

4. Valve according to claim 1 , wherein the first part connected with the diaphragm and the second part connected with the vent are provided, wherein the first part is releasably connected with the second part, particularly by screwing or clamping, wherein the diaphragm covers the discharge opening for constituting an unidirectional valve.

5. The valve according to claim 1 , wherein the connecting area surrounds the closing area.

6. Bowl for receiving and/or mixing fluids, comprising
a vessel for receiving and/or mixing the fluids, the vessel comprising a rigid vessel body for bordering a use volume, and
a stand adapted to be placed below the vessel for placing the vessel onto a ground, the stand comprising a vent for injecting a fluid from below,
wherein the vessel comprises a flexible diaphragm for covering the vent, wherein the diaphragm and the vent constitute a unidirectional valve according to claim 1 , when the vessel is received by the stand in a designated use position.

7. Bowl according to claim 6 , wherein the vessel body comprises a bottom opening closed by the diaphragm, wherein the diaphragm is fixed to the vessel body, by 2-component injection or insertion molding.

8. Bowl according to claim 6 , wherein the diaphragm is made from TPE, TPS, TPO, TPV, rubber or silicone and/or the vessel body is made from a thermoplastic material being SAN or PP.

9. Bowl according to claim 6 , wherein the diaphragm is adapted to increase a closing force for closing the discharge opening when the hydrostatic pressure above the inlet means increases.

10. Bowl according to claim 6 , wherein the connecting area of the diaphragm comprises an extension protruding mainly upwards and/or mainly downwards, wherein the extension is fixed to the vessel body.

11. Method for receiving and/or mixing fluids, comprising the steps of
providing a bowl according to claim 6 , wherein the vessel is connected with the stand,
connecting the vent of the stand with a discharge stem of an aerosol can and/or a pump dispenser,
subsequently injecting a fluid in the aerosol can and/or the pump dispenser into the vessel via the unidirectional valve of the bowl,
subsequently mixing and/or applying the fluid located inside the vessel,
subsequently detaching the vessel from the stand and
subsequently cleaning the vessel separated from the stand.

12. Method according to claim 11 , wherein the vessel and the stand are cleaned at different times and/or different places.

13. Method according to claim 11 , wherein the vessel and/or the stand are cleaned by brushing and/or rinsing.

14. Method according to claim 13 , wherein the vessel is connected with the stand after cleaning the vessel and/or the stand.

15. Valve comprising
a vent for injecting a fluid, wherein the vent comprises an inlet connected to a discharge opening via a discharge channel, and
a flexible diaphragm for covering the discharge opening of the vent,
wherein:
(i) the diaphragm is separated from the vent,
(ii) the diaphragm is adapted to be connected to a bowl vessel body,
(iii) the vent is adapted to be connected to a bowl stand,
(iv) the diaphragm comprises a closing area for closing the discharge opening and a connecting area configured for connecting the diaphragm with the bowl vessel body,
(v) the connecting area is spaced to the vent,
(vi) the connecting area surrounds the closing area,
(vii) at least one window is provided between the closing area and the connecting area, and
(viii) the connecting area is connected with the closing area via bridges, wherein each window is bordered by the closing area, the connecting area and two bridges,
and wherein the valve is further configured such that
(ix) when the discharge opening is closed by the closing area, the closing area is located on a plane higher than the bridge, and/or
(x) when the discharge opening is closed by the closing area, the bridge slopes downward radially from the closing area to the connecting area, and/or
(xi) the connecting area has a thickness defined by a distance between a top and a bottom surface thereof, wherein said thickness is the same as that of the bridges or the window.
