Abstract
The utility model relates to a stainless steel vacuum thermal cup, comprising a cup body, a cup cover and an inner container. The utility model is characterized in that the bottom of the inner container is in upward convex arc shape; the inner surface of the inner container is smooth; the cup body of the cup cover and a threaded plug cock are positioned in circumferential direction by adopting the tight fit method of four convex ribs and four open grooves, wherein, the four convex ribs are positioned on the top of the interior of the cover body; the four open grooves are positioned on the upper end part of the threaded plug cock. The utility model has the advantages of reasonable structure, low bacteria stocking ability, difficult looseness between the cover body and the threaded plug cock, and high durability.
Description
The utility model relates to thermos cup, particularly a kind of stainless steel high vacuum thermos cup.
The stainless steel thermos cup is a kind of new product that grew up in recent years, and it has corrosion-resistant, sanitation and hygiene, durable in use, advantage such as cracky not.Though existing stainless steel thermos cup has overcome the deficiency of traditional pottery, glass heat-insulating cup, it still leaves following defective.1. owing to show in the inner bag to adopt chemical method to handle, so rough inner surface adheres to bacterium easily, easy cleaning does not influence attractive in appearance; 2. being shaped as of inner bag bottom arcs of recesses down, this shape are for polishing and extend and all compare difficultly, can increase its processing cost; 3. in bowl cover, lid adopts four small convex ribs to cooperate with two symmetric windows with the screw thread cock, and this structure in use, and is loosening easily between lid and the screw thread cock, and four convex tendon discontinuity are fragile.
The purpose of this utility model is in order to solve the defective that the above-mentioned background technology exists, and proposes a kind ofly to use reliably, is difficult for becoming flexible, is easy to clean, stainless steel high vacuum thermos cup easy to process.
At the foregoing invention purpose, the utility model adopts following technical scheme.A kind of stainless steel high vacuum thermos cup is made up of cup, inner bag and bowl cover, and bowl cover comprises lid and screw thread cock, and its special character is: convex is presented in described inner bag bottom, and the roughness of inner bag inner surface is
, adopt four convex tendons and four friction tight modes of open slot circumferentially to locate between lid in the described bowl cover and the screw thread cock, wherein, four convex tendons are positioned at the lid inner top, and four open slots are positioned at screw thread cock upper end.
The utility model is rational in infrastructure, is difficult between the lid of bowl cover and the screw thread cock becoming flexible, and four small convex ribs are stressed evenly, not fragile on the lid.Because the inner bag bottom is adopted and is gone up convex appearance, so the inner surface of inner bag adopts the method for machine glazed finish to polish easily, processing cost is reduced, in addition, the inner bag of inner wall smooth is difficult for adhering to bacterium, is easy to clean very health.
Below in conjunction with embodiment shown in the drawings, describe the utility model in detail.
Fig. 1 is the utility model structural representation.
