  • Patent number: 5732855
    Abstract: A spray head is intended for attachment to a spray can having a pressure container, a control valve and an outflow channel for dispensing material, such as shaving gel, which expands after dispensing. The spray head has a flow channel that receives a biassed valve near the spray head outlet. A material expansion absorption arrangement is in communication with flow channel and interacts with a control part that controls spray head operation. The threshold pressure of the biassed valve is higher than the threshold pressure needed for operating the material expansion absorption arrangement. After dispensing a quantity of material, the material expansion absorption arrangement can absorb expanding residual material so that on subsequent use, the material expansion absorption arrangement is returned first to the initial position before the control valve of the spray can is opened. A spray can with such a spray head is also described.
