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. A bowl adapted for receiving and/or mixing fluids, comprising:
a vessel adapted for receiving and/or mixing the fluids, the vessel comprising a rigid vessel body for bordering a use volume;
a stand placed below, and receiving, the vessel for placing the vessel onto a ground;
a measuring cylinder; and
a unidirectional valve adapted for injecting a fluid into the measuring cylinder and/or into the use volume, wherein the valve comprises
a vent, adapted for injecting a fluid, covered by a flexible diaphragm, wherein the vent comprises an inlet connected to a discharge opening via a discharge channel and the
flexible diaphragm covers the discharge opening of the vent,
wherein the diaphragm comprises a holding collar adapted for receiving the measuring cylinder,

wherein the measuring cylinder is received by the holding collar.

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

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

4. The bowl according to claim 1 , wherein a first part connected with the diaphragm and a second part connected with the vent are provided, wherein the first part is releasably connected with the second part, screwing or clamping, wherein the diaphragm covers the discharge opening for providing an unidirectional valve.

5. The bowl according to claim 1 , wherein a connecting area is radially spaced to a closing area, wherein the connecting area is connected with the closing area via at least two bridges, wherein particularly at least one window is bordered by the closing area, the connecting area and the at least two bridges.

6. The bowl according to claim 1 , 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.

7. The bowl according to claim 1 , wherein the diaphragm is made from thermoplastic elastomer, thermoplastic elastomer based on olefins, cross-linked and/or vulcanized thermoplastic elastomer based on olefins, cross-linked and/or vulcanized thermoplastic elastomer based on styrol block copolymers, rubber or silicone and/or the vessel body is made from a thermoplastic material being styrene-acrylonitrile resin or polypropylene.

8. The bowl according to claim 1 , wherein the diaphragm is adapted to increase a closing force for closing the discharge opening when the hydrostatic pressure above the inlet increases.

9. The bowl according to claim 1 , wherein a connecting area of the diaphragm comprises an extension protruding mainly upwards and/or mainly downwards, wherein the extension is fixed to the vessel body.

10. A method comprising
providing the bowl according to claim 1 , wherein the vessel is connected with the stand,
connecting the vent of the stand with a discharge stem, and
subsequently injecting a fluid into the vessel via the unidirectional valve provided by the vent and the flexible diaphragm covering the vent.

11. The method according to claim 10 , wherein the vessel and the stand are cleaned at different times and/or different places.

12. The method according to claim 10 , wherein the vessel and/or the stand are cleaned by brushing and/or rinsing.

13. The method according to claim 10 , wherein the vessel is connected with the stand after cleaning the vessel and/or the stand.

14. A bowl adapted for receiving and/or mixing fluids, comprising:
a vessel adapted for receiving and/or mixing the fluids, the vessel comprising a rigid vessel body for bordering a use volume;
a stand adapted to be placed below the vessel for placing the vessel onto a ground;
a measuring cylinder; and
a unidirectional valve for injecting a fluid into the measuring cylinder and/or into the use volume, wherein the unidirectional valve comprises:
a vent adapted for injecting a fluid, wherein the vent comprises an inlet connected to a discharge opening via a discharge channel; and
a flexible diaphragm covering the discharge opening of the vent,
wherein the diaphragm comprises a holding collar adapted for receiving the measuring cylinder,

wherein
the measuring cylinder is received by the holding collar,
the vessel body comprises a bottom opening closed by the diaphragm, wherein the diaphragm is fixed to the vessel body by two-component injection or two-component insertion molding such that the vessel is manufactured by one molding process using two different materials for the vessel body and the diaphragm.

15. The bowl according to claim 14 , wherein the diaphragm is made from thermoplastic elastomer, thermoplastic elastomer based on olefins, cross-linked and/or vulcanized thermoplastic elastomer based on olefins, cross-linked and/or vulcanized thermoplastic elastomer based on styrol block copolymers, rubber or silicone and the vessel body is made from a thermoplastic material being styrene-acrylonitrile resin or polypropylene.
