  • Publication number: 20170184348
    Abstract: An automobile interior temperature stabilizer includes a holder adapted for placing within a vehicle cabin and a temperature stabilizing member which is made of latent heat material that absorbs and releases heat without rising in its temperature and is disposed in the holder, wherein the temperature stabilizing member has a threshold temperature range that the temperature stabilizing member is arranged for absorbing cabin heat within the vehicle cabin to cool down the vehicle cabin when an interior temperature of the vehicle is higher than the threshold temperature range, and the temperature stabilizing member is arranged for releasing stored heat to the vehicle cabin to warm the vehicle cabin when an interior temperature of the vehicle is lower than the threshold temperature range. Therefore, the automobile interior temperature stabilizer is able to maintain the cabin temperature of the vehicle without using any power from the vehicle.

  • Patent number: 8216195
    Abstract: A dispenser cap for an eye-drop container includes a cap holder, an eyelid-engaging member, and a cap enclosure pivotally extended from the cap holder alongside the eyelid-engaging member. The eyelid-engaging member has topside adapted for contacting with an eyelid of a user to maintain the eyelid in an opened position. The cap enclosure is outwardly folded away from the eyelid-engaging member for exposing the dispensing nozzle and is folded in to engage with the eyelid-engaging member to create a nozzle cavity for enclosing the dispensing nozzle. Therefore, the dispenser cap not only provides a sealing device for enclosing the dispensing nozzle of the eye-drop container but also forms an eyelid retractor for maintaining the eyelid of the user in an opened position and aligning the dispensing nozzle to the eye of the user.
