Abstract

A water cup with a replaceable inner flask is characterized in that the inner flask is retained inside an external shell by a cylindrical plug cork with a screw thread arranged on the periphery and a tubular shell with an R angle arranged at the opening and an internal thread arranged at the tail, the upper opening of the inner flask is pressed against the R angle of the opening of the tubular shell, the bottom end face of the inner flask is pressed against the plug cork, and the plug cork is connected with the tail of the tubular shell through a screw thread. The water cup is of excellent heat-insulation property, hand-scald safe, portable, anti-broken and of a function of inner flask replacing.

Description

The water tumbler of replaceable inner bag

Technical field

The utility model relates to water tumbler, a kind of double-deck water tumbler that is made of shell and inner bag of more specifically saying so.

Background technology

Purple ceramic cup in the market, ceramic cup, glass etc. scald one's hand in use and are frangible, insulating power is poor, and can not change behind the interior gallbladder break of double-deck water tumbler, cause and to continue to use, the water tumbler of double-layer stainless steel costs an arm and a leg, and its stainless steel inner container material changes the mouthfeel of tea beverage easily.

The utility model content

The utility model proposes a kind of good heat insulating, non-scald on hand, is easy to carry and has the water tumbler of good anti-crushing and replacing inner bag function at above-mentioned deficiency.

The technical scheme that its technical problem that solves the utility model adopts is:

The design feature of the water tumbler of the replaceable inner bag of the utility model is that to have R angle, afterbody be that the tubular shell of internal thread is clamped in inner bag in the external shell for threaded cylindrical cock of peripheral zone and oral area; The oral area R angle that is butted on tubular shell suitable for reading of described inner bag, the bottom end face of inner bag is butted on cock, and cock is to be threaded in the afterbody of tubular shell.

Design feature of the present utility model also is:

Mouth sealing ring is being set between R angle and the inner bag.

The cock upper surface is concavo-convex the cooperation with the inner bag bottom surface.

Bottom is set, and bottom snaps onto on the end mouth outer wall of tubular shell.

Between tubular shell and inner bag, be formed with the sidepiece cavity.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, the utlity model has good heat insulating, non-scald on hand, be easy to carry, good anti-crushing and change the function of inner bag.

2, the design at the shell oral area R angle in the utility model can make inner bag locate automatically when assembling, and assembly technology is simple, and is easy to implement.

3, the setting of mouth sealing ring promptly can be sealed the oral area space between inner bag and the shell in the utility model, also has the function of buffering antidetonation concurrently.

4, the utility model is formed with cavity between inner bag and shell, improves heat insulating ability on the one hand, has solved anti-scald problem on the other hand, and it is simple and reasonable for structure.

Description of drawings

Fig. 1 is the utility model structural representation.

Number in the figure: 1 bowl cover, 2 bowl cover sealing rings, 3 are mouth sealing ring on the R angle, 4,7 inner bags, 8 shells, 10 cocks, 12 convex tendons, 13 bottoms.

The specific embodiment

Referring to Fig. 1, it is that the tubular shell 8 of internal thread is clamped in inner bag 7 in the external shell that the threaded cylindrical cock 10 of peripheral zone and oral area have R angle 3, afterbody; The oral area R angle 3 that is butted on tubular shell 8 suitable for reading of inner bag 7, the bottom end face of inner bag 7 is butted on cock 10, and cock 10 is to be threaded in the afterbody of tubular shell 8.

In concrete the enforcement, the corresponding structure setting also comprises:

Between R angle 3 and inner bag 7, mouth sealing ring 4 is set, is used to seal the oral area gap between shell and the inner bag, can prevent effectively that the liquid in the inner bag from flowing in the space.

Cock 10 upper surfaces are set to concavo-convex the cooperation with inner bag 7 bottom surfaces.Be beneficial to the location of inner bag 7 in cock 10, along with the screw-in of cock 10, the bottom of inner bag 7 is positioned in its concave surface, meanwhile by cock 10, because cock 10 is along moving on the housing axis direction, the oral area of inner bag 7 also can be butted on the inboard at R angle 3 across last mouth sealing ring 4.

Bottom 13 is set, and bottom 13 snaps onto on the end mouth outer wall of tubular shell 8, can convex tendon 12 be set on the relevant position of tubular shell 8, and bottom 13 snaps onto on the convex tendon 12.

Between tubular shell 8 and inner bag 7, be formed with the sidepiece cavity, be beneficial to improve heat insulation effect.

Only need take off bottom 13, screw out cock 10, promptly replaceable inner bag 7.

Bowl cover 1 and bowl cover sealing ring 2 are set routinely, and the neck of bowl cover 1 and shell 8 is with threaded engagement

In concrete the enforcement, the material of shell 8 can be stainless steel or plastics, and inner bag 7 can be that glass, boccaro, pottery etc. comprise and are not limited to above-mentioned material.
