Description
Technical Field
The invention relates to a cup cover for sealing a cup opening of a cup, in particular to a heat insulation cup cover.
Background
In the existing vacuum cup, the cup body generally adopts vacuum heat insulation for long-term heat preservation, but heat can be transmitted outwards through the cup cover to cause heat loss, so that the cup cover can be warm when people touch the cup cover of the vacuum cup; the liquid in the vacuum cup can continuously dissipate heat, and the overall heat preservation effect is influenced. In addition, the heat insulation mode of the cup cover is improved in the industry, foam or other heat insulation materials are mainly filled (in a more economic mode) at present, and the cup covers with the existing vacuum interlayer are rarely used (the effect is better) in two years.
For example, patent number ZL201320494524.1 "vacuum cup lid", which includes an outer lid 1 with one closed end, an inner lid 3 with one closed end, and a protrusion 6, wherein the protrusion 6 is disposed at the closed end of the inner lid 3 and extends to the open end of the inner lid 3, the outer lid 1 is sleeved outside the inner lid 3, and a sealing ring 12 is disposed at the joint between the protrusion 6 and the inner lid 3. The protruding part 6 is double-layer, the top end of the protruding part is provided with a vacuumizing hole 10, air in the cup cover is pumped out in the manufacturing process, and the vacuumizing hole 10 is welded and sealed through a tailless vacuum technology.
For example, the patent number ZL201310310370.0 vacuum cover comprises a cover bottom 1 and a cover body 2 fixedly connected with the cover bottom 1, wherein the cover body 2 is made of heat insulating materials, and the inner side wall of the cover body 2 is matched with the outer side wall of a cup body for detachable connection; the vacuum container 3 is positioned inside the cover body 2 and the cover bottom 1, and the vacuum container 3 is inserted into the inner side of the cup body and is connected with the cup body in a sealing way; a plurality of limiting bulges 31 are formed on the side wall of the vacuum container 3, a plurality of limiting grooves 21 are correspondingly formed on the inner side wall of the cover body 2, and the limiting bulges 31 are matched with the limiting grooves 21 to realize the fixed connection of the vacuum container 3 and the cover body 2; an extension part 22 extending towards the vacuum container 3 is formed on the upper side of the inner wall of the cover body 2, and the extension part 22 forms the limiting groove 21.
However, both of the above solutions have some problems: protruding portion 6 or vacuum courage 3 direct and thermos cup inner space contact, the inside heat of thermos cup can be directly toward outer transmission along the stainless steel matter of vacuum courage, leads to the heat to give off fast, reduces the heat preservation effect.
