Definitions

  • This invention relates to a cork for thermos flask , in particular , to an efficient cork for thermos flask.
  • thermos flask In the past , people put emphasis throughout on enhancing the quality of glass liner to improve the performance of heat preservation for the thermos flask, for example , by increasing vacuum , improving the silver-plating , or varying the prescription of the liner etc. The result is that an expensive cost has to be paid for heightening each degree of temperature. In fact , the cork is also a key factor which can effect the performance of heat preservation.
  • the object of the present invention is to improve the sealing condition between the cork and the mouth of flask thus to reduce the loss of heat and prolong the period for heat preservation.
  • thermos flask manufactured according to the way of the present invention , the daily index of heat preservation will be increased about 10°C relative to present international I. S.O. standard and the standard of the Ministry of Light Industry of P.R.C.: QB 81-8.
  • the cork of present invention comprises a cork 1, whose height is between 15-50mm, a plastic spacer 2 and a plastic bowl-like sleeve 3.
  • cork 1 there is a funnel through hole 11 .
  • the spacer 2 assumes a shape of wheel boss , where an end is sealed.
  • Said plastic spacer 2 is formed by means of injection moulding on its first make.
  • the cylinder 10 on the plastic bowl-like sleeve 3 passes through said through hole 9 in said plastic spacer 2 and said funnel through hole 11 in the cork 1 and then the top of the cylinder 10 is hot-pressed and formed.
  • said cork 1 , plastic spacer 2 and bowl-like sleeve 3 are hot riveted to an integral whole.
  • the spaces 4 and 7 are air heat insulation layers formed by hot riveting separately.
  • This embodiment has substantially the same elements and structure with embodiment 1.
  • the cork of present invention comprises plastic spacers 2, 2′ , a plastic bowl-like sleeve 3 , a plastic base frame 12, a plastic cover 13 of the base frame and a plastic handle 14.
  • the cylinder 10 on the plastic bowl-like sleeve 3 passes through the cylindrical holes , which include holes in said plastic spacers 2, 2′ , in said base frame 12, in said plastic cover 13 and in said handle , and all of them will be hot riveted to an integral whole, the space 4 , 7 , 7′ , 15 are air heat insulation layers formed by hot riveting separately.
  • the outer diameter of said plastic base frame 12 is ⁇ 30-150mm, and the smaller diameter of the taper portion is ⁇ 25-100mm.
  • the cork in accordance with the present invention should be inserted into the mouth of the thermos flask vertically.
  • the bowl-like ring 6 and the resilient ring 8 or resilient rings 8 , 8′ ) will be crushed out of shape with said mouth of flask due to heat , thereby the three or four layers of sealing ring are formed by said rings 6 and 8 together with said cork 1 or said plastic base frame 12, so that the sealing condition is strengthened, the gradient of conduction of heat is improved , then the object of the present invention is achieved, i.e, the loss of heat is reduced and the period of heat preservation is prolonged.
  • plastic spacer 2 plastic bowl-like sleeve 3 , plastic base frame 12 and plastic cover 13 of the base frame are made all the same by polyethylene or other nonpoisonous thermoplastics by means of injection moulding.
  • This invention has the effect that the loss of heat is reduced and the period for heat preservation is prolonged.
