  • Patent number: 11904662
    Abstract: A thermal insulation device includes a film unit including inner and outer layers and a thermal insulation unit. The outer layer is mounted to a window of a vehicle. The inner layer has a peripheral portion connected sealingly to the outer layer, and a center portion spaced apart from and cooperating with the outer layer to define a thermal insulation space therebetween. The film unit is formed with inlet holes communicating with the thermal insulation space and a seating space of the vehicle, and outlet holes communicating with the thermal insulation space and open toward the bodyshell, such that air in the seating space flows into the thermal insulation space through the inlet holes and is discharged from the thermal insulation space toward the bodyshell through the outlet holes. The thermal insulation unit includes a heat insulation layer disposed on the outer layer.

  • Publication number: 20200054157
    Abstract: A paper straw has an inner tube, an outer tube, and a pattern portion. The inner tube and the outer tube are both tubular bodies formed by spirally winding paper sheets. The pattern portion is disposed between the inner tube and the outer tube. The paper sheets that are used to wind the inner tube and the outer tube have light-transmissive properties. Then the pattern portion can be externally displayed through the outer tube or the inner tube, and this can avoid the pattern portion directly contacting food or human body.
