Abstract

The invention relates to a container for sunscreen agent in which the sunscreen agent has a specific predetermined sun-protection factor, comprising a sealing device (2) by which the container (1) can be closed to make its opening (8) completely sealed, the container (1) being provided with at least one sun sensor (3) arranged to indicate the current UV intensity by changing its hue depending on the UV intensity of the radiation striking the sensor (3), said container further comprising a colour-reference range (4) for comparative reading of the hue of the sensor to enable the determination of UV intensity, and time indicator (50) for determining the period of time during which a person of a specific skin type can expose his or her skin to solar radiation at said determined UV intensity without sunburn arising, provided said person has applied the sunscreen agent from the container to the skin, said sun sensor (3) being arranged as an integral part of the container (1) and being positioned such that it is completely covered by the sealing device (2) when the sealing device (2) is sealed.

Claims

1-5. -5. (canceled)

6. A container for sunscreen agent in which the sunscreen agent has a predetermined sun-protection factor, comprising:

a sealing device configured to close the container and completely seal an orifice of the container;

at least one sun sensor configured to indicate a current UV intensity by changing its hue depending on UV intensity of radiation striking the at least one sun sensor;

a color-reference range configured for comparative reading of the hue of the sensor to enable a determination of UV intensity, and

a time indicator configured for determining a period of time during which a person of a specific skin type can expose his or her skin to solar radiation at the determined UV intensity without sunburn arising, provided the person has applied the sunscreen agent from the container to the skin.

7. The container according to claim 6, wherein the sun sensor is an integral part of the container.

8. The container according to claim 7, wherein the sun sensor is positioned such that it is completely covered by the sealing device when the sealing device is sealed.

9. The container according to claim 6, wherein the sun sensor comprises photochromic ink that changes its hue when in contact with UV radiation.

12. A method for determining safe tanning time, the method comprising:

removing a sealing device from an orifice of a container having a sunscreen agent to uncover a sun sensor;

exposing the sun sensor to UV radiation such that the sun sensor changes its hue;

comparing the hue of the sun sensor to a predetermined color range to determine current UV intensity;

determining a skin type using a skin-type table; and

determining a safe tanning time based upon a UV intensity and skin type in a sun matrix.
