A squeeze dispenser for liquids, preferably relatively highly viscous liquids, is provided with a flexible holder (1) with an outflow opening (2) via which a liquid can be pressed out of the holder, and with a sealing element (3) arranged over this outflow opening. In this sealing element, a first valve (12) is arranged via which, when the holder is squeezed, liquid can be pressed out of the holder, as well as a second valve (18) for admitting air into the holder when the holder is no longer squeezed.

1. A squeeze dispenser for highly viscous liquid having a flexible holder, the holder comprising:a sealing element; an outflow opening covered by the sealing element, wherein highly viscous liquid is pressed out of the flexible holder through the outflow opening; a first valve covered by the sealing element, wherein highly viscous liquid is pressed out of the flexible holder through the first valve when the holder is squeezed the first valve normally closed but is opened under pressure of the highly viscous liquid as it is squeezed out; a second valve covered by the sealing element, wherein air is admitted into the flexible holder through the second valve when the holder is released; a riser having a terminal end, the terminal end terminating in the first valve; and a ball disposed in the terminal end of the riser adjacent the first valve, wherein when the holder is released the ball blocks the first valve and air is sucked into the second valve. 2. A squeeze dispenser according to claim 1, wherein the first valve is active in a surface of the sealing element perpendicular to the outflow direction of the liquid from the holder and the second valve is active in a side surface of the sealing element.3. A squeeze dispenser according to claim 1, wherein the sealing element comprises a first closing part which can be secured on the holder and a second closing part which can be secured over the first closing part, the second closing part comprising at least partly a flexible part which, together with the first closing part, forms the first valve.4. A squeeze dispenser according to claim 3, wherein at least the upper portion of the riser forms part of the first closing part and the extremity of the riser is situated opposite said flexible part.5. A squeeze dispenser according to claim 3, wherein the second valve is formed by a lip which is active between the two closing parts.6. A squeeze dispenser according to claim 3, wherein the holder and the two closing parts are manufactured from plastic by injection molding, the plastic material of the second closing part being softer than that of the holder and the first closing part.7. A squeeze dispenser for liquids, preferably relatively highly viscous liquids, provided with a flexible holder with an outflow opening via which a liquid can be pressed out of the holder, and with a sealing element arranged over this outflow opening, wherein in this sealing element a first valve is arranged via which, when the holder is squeezed, liquid can be pressed out of the holder, as well as a second valve for admitting air into the holder when the holder is no longer squeezed, wherein the holder provided with a riser, one end of which terminates in the first valve, in addition to the first valve a ball being provided in the extremity of the riser located adjacent the first valve, which can close off the riser, wherein the sealing element comprises a first closing part which can be secured on the holder and a second closing part which can be secured over the first closing part, the second closing part comprising at least partly a flexible part which, together with the first closing part, forms the first valve, wherein the second valve is formed by a lip which is active between the two closing parts, and wherein the first closing part is provided with at least one opening, via which air, let through by the second valve, can flow into the holder.8. A squeeze dispenser for liquids, preferably relatively highly viscous liquids, provided with a flexible holder with an outflow opening via which a liquid can be pressed out of the holder, and with a sealing element arranged over this outflow opening, wherein in this sealing element a first valve is arranged via which, when the holder is squeezed, liquid can be pressed out of the holder, as well as a second valve for admitting air into the holder when the holder is no longer squeezed, wherein the holder provided with a riser, one end of which terminates in the first valve, in addition to the first valve a ball being provided in the extremity of the riser located adjacent the first valve, which can close off the riser, wherein the sealing element comprises a first closing part which can be secured on the holder and a second closing part which can be secured over the first closing part, the second closing part comprising at least partly a flexible part which, together with the first closing part, forms the first valve, and wherein a sealing lip is present for blocking a liquid flow to the space between the first and second closing part via which air, let through by the second valve, can flow to said opening in the first closing part.9. A squeeze dispenser for liquids, preferably relatively highly viscous liquids, provided with a flexible holder with an outflow opening via which a liquid can be pressed out of the holder, and with a sealing element arranged over this outflow opening, wherein in this sealing element a first valve is arranged via which, when the holder is squeezed, liquid can be pressed out of the holder, as well as a second valve for admitting air into the holder when the holder is no longer squeezed, wherein the holder provided with a riser, one end of which terminates in the first valve, in addition to the first valve a ball being provided in the extremity of the riser located adjacent the first valve, which can close off the riser, wherein the first valve is active in a surface of the sealing element perpendicular to the outflow direction of the liquid from the holder and the second valve is active in a side surface of the sealing element, and wherein the plane in which the second valve is active is substantially perpendicular to that in which the first valve is active.
