Description
Technical field
The utility model relates to heat preservation dinner flask, particularly relates to the sealing and connecting device between heat preservation dinner flask inner bag and the centre circle, belongs to daily living article.
Background technology
The staving of heat preservation dinner flask comprises shell, inner bag and heat-insulation layer, the oral area of inner bag with housing is sealed mutually by centre circle at bung, and the top of centre circle cooperates with bung simultaneously.Described inner bag is generally made by metal materials such as stainless steel or stainless irons, prior art at first adopts the centre circle of plastic injection-moulded one-tenth annular, adopt in addition metal material to make the connector of 7 fonts or two 7 fonts, totally two kinds of shapes, the connected mode of two kinds of shapes is different, if 7 fonts then inner bag insert downwards in the centre circle from the top of centre circle, it connects cross section as shown in Figure 3, inner bag is interior, and centre circle outside; If two 7 fonts then inner bag upwards be enclosed within outside the centre circle from the bottom of centre circle, it connects cross section as shown in Figure 4, inner bag outside, and centre circle is interior.These two kinds of structures are inserted in the centre circle owing to inner bag or are enclosed within outside the centre circle, and the one, connection reliability is poor; The 2nd, exist the slit in the junction, can infiltrate in the slit when cleaning good-for-nothing Shi Shui, cause seepage and pollution.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, to provide a kind of connection firm, eliminate the slit, cleaning easily, and is non-leakage, the sealing and connecting device of free of contamination heat preservation dinner flask inner bag and centre circle.
The technical scheme of the sealing and connecting device of the utility model heat preservation dinner flask inner bag and centre circle is, the metal inner tube of a drum-shaped, connect centre circle on the metal inner tube, the oral area that it is characterized in that metal inner tube is shaped with flange, with metal inner tube as inserts bluff piece, lower bluff piece and vertical circle on the centre circle of flange integrated injection molding has, upper bluff piece and lower bluff piece are enclosed in the outside of flange, and vertical circle matches with bung.
The utility model discloses the sealing and connecting device of a kind of heat preservation dinner flask inner bag and centre circle, the metal of a drum-shaped (comprising that stainless steel or stainless iron etc. are made) inner bag, the oral area of metal inner tube is shaped with outside flange, with metal inner tube as inserts, flange injection moulding centre circle at metal inner tube, centre circle has upper bluff piece and lower bluff piece flange to be enclosed in middle, upper and lower bluff piece surrounds flange, and be to be injection molded into one, make inner bag very firm with being connected of centre circle, the junction does not have the slit, does not seep water during cleaning, can not cause in the junction dirty mixing, health is clean.
The sealing and connecting device of heat preservation dinner flask inner bag of the present utility model and centre circle, the head of described flange is shaped with crimping.There had crimping that bluff piece is connected to be more reliable, and crimping can prevent from making the time flanging mouth scratch finger.Described centre circle is shaped with lower connecting ring, and lower connecting ring matches with the good-for-nothing shell.Metal inner tube has heat-insulation layer outward during fabrication, and heat-insulation layer has shell outward, and shell links to each other with centre circle, thus by centre circle inner bag, heat-insulation layer and shell are connected together, and the good-for-nothing mouth is sealed.

Fig. 2 is the partial enlarged drawing of Fig. 1;
Fig. 3 is a kind of connected mode schematic diagram of existing inner bag and centre circle;
Fig. 4 is the another kind of connected mode schematic diagram of existing inner bag and centre circle.
The specific embodiment
The utility model relates to the sealing and connecting device of a kind of heat preservation dinner flask inner bag and centre circle, as shown in Figure 1 and Figure 2, the metal inner tube of a drum-shaped, connect centre circle on the metal inner tube, the oral area that it is characterized in that metal inner tube 1 is shaped with flange 11, as inserts bluff piece 21, lower bluff piece 22 and vertical circle 23 on the centre circle of flange 11 integrated injection moldings has, upper bluff piece 21 and lower bluff piece 22 are enclosed in the outside of flange with metal inner tube 1, and vertical circle 23 matches with bung.The metal of a drum-shaped (comprising that stainless steel or stainless iron etc. are made) inner bag, the oral area of metal inner tube 1 is shaped with outside flange 11, with metal inner tube as inserts, at the flange injection moulding centre circle 2 of metal inner tube, centre circle has upper bluff piece 21 and lower bluff piece 22 flange to be enclosed in middle, upper and lower bluff piece surrounds flange, and is to be injection molded into one, makes inner bag very firm with being connected of centre circle, the junction does not have the slit, do not seep water during cleaning, can not cause in the junction dirty mixing, health is clean.The head of described flange 11 is shaped with crimping 12.There had crimping that bluff piece is connected to be more reliable, and crimping can prevent from making the time flanging mouth scratch finger.Described centre circle 2 is shaped with lower connecting ring 24, and lower connecting ring 24 matches with the good-for-nothing shell.Metal inner tube has heat-insulation layer outward during fabrication, and heat-insulation layer has shell outward, and shell links to each other with centre circle, thus by centre circle inner bag, heat-insulation layer and shell are connected together, and the good-for-nothing mouth is sealed.
