Abstract

The utility model relates to a medical thermos flask which comprises a flask cover, a cylinder body and an inner liner, and is characterized in that the flask cover is formed by connecting an upper cover and a lower cover in a welding way; the flask cover is connected with a body of the cylinder body by a screw thread; the inner liner is in an inner drum shape; the wall of the inner liner is welded with the bottom of the inner liner to form the inner liner; an opening of the inner liner is provided with a flask mouth sealing ring; the inner liner is connected with the cylinder body by screw thread; a gap between the inner liner and the cylinder body is filled with polyurethane in a foaming way; the body of a cylinder is connected with the bottom of the cylinder in a welding way to form the cylinder body; the bottom of the cylinder is provided with a choke plug; and the top of the cylinder body is provided with a spout. The medical thermos flask has the advantages that under the same capacity and heat preservation requirement, the product has minimum volume, simple structure and drop resistance, can be washed and disinfected in a dish-washing machine at 11 DEG C, and is light, convenient for use, sanitary and safe.

Description

Medical thermo jug

Technical field

This utility model relates to a kind of cool-bag, particularly a kind of medical thermo jug.

Background technology

The most important for medical thermo jug is exactly the disinfectant problem, dish-washing machine cleans and sterilization and general thermo jug can't be put into, so medical thermo jug is all selected the cool-bag of all-plastic for use, the inner bag of present existing all-plastic cool-bag can be divided into directly barrel-shaped, interior cydariform.Straight barrel-shaped general with the molding of injection moulding mode, but capacity is little relatively under the urceolus barrel space that waits that coexists, interior cydariform generally will be made molding with the blowing mode, and its maximum shortcoming is that wall unevenness is even, finish dimensional is restive accurate, influences sealing effectiveness.In addition, interior cholic fixed form generally adopts bottom supporting, and such fixed form mould structure complexity, and make cool-bag can't be put in cleaning and sterilization in the dish-washing machine.

Summary of the invention

The purpose of this utility model is at the defective that exists in the prior art, a kind of medical thermo jug is provided, comprise: pot lid, cylindrical shell and inner bag, it is characterized in that pot lid is by loam cake, lower cover connects to form through the mode of ultrasonic bonding, pot lid adopts with the stack shell of cylindrical shell and is threaded, inner bag is interior drum shape, adopt the mode of spinning friction welding to form inner bag at the bottom of wall of inner container and the inner bag, in cholic oral area bottleneck sealing ring and stack shell be housed adopt the crush seal circle also of being threaded to reach the effect of sealing, the crush seal circle reached the effect of sealing when pot lid rotated to lower dead center, gap between inner bag and the stack shell is that polyurethane foam is filled, increase medical thermo jug heat insulation function with this, stack shell adopts the mode of spinning friction welding to form cylindrical shell with the tube end, and a tube end is provided with foaming exhaust air technique hole, by shutoff foaming exhaust air technique hole silently, sealing ring silently silently and between at the bottom of the tube, the top of cylindrical shell is provided with Hu Zui.

The utility model has the advantages that under equal capacity and insulation require, the volume minimum of product, dish-washing machine simple in structure, anti-drop, as can to put into 110 ℃ carries out cleaning in 30 minutes, sterilization, and product is light and handy, easy to use, health, safety.

The specific embodiment

Further specify embodiment of the present utility model below in conjunction with accompanying drawing.

Referring to Fig. 1, Fig. 4, pot lid is connected to form through the technology of ultrasonic bonding by loam cake 2, lower cover 1, adopt between the stack shell 5 of pot lid and cylindrical shell and be threaded, inner bag is interior drum shape, utilizes minimum space, and maximum capacity is provided, in order to guarantee the precision of kettle body oral area, inner bag is designed to 6 two parts at the bottom of inner bag 5 and the inner bag, is wedge mouth syndeton between 6 at the bottom of wall of inner container 5 and the inner bag, referring to Fig. 6.Wall of inner container 5 is welded to form inner bag with the technology of 6 employing spinning friction weldings at the bottom of the inner bag, in adopt between cholic oral area and the stack shell 4 and be threaded, interior cholic oral area is provided with bottleneck sealing ring 3, interior cholic bottleneck sealing ring 3 is inlaid between the screw thread of interior cholic oral area screw thread and stack shell 4, with stack shell 4 rotate to compress sealing ring 3 till, so just play the requirement of the sealing between inner bag and the stack shell.Inboard inside, a protruding upward sealing projection 10 of bottleneck sealing ring 3 is referring to Fig. 5.The lower cover 1 terminal outer wall of pot lid is an inside inclined-plane, offset with the sealing projection 10 on the bottleneck sealing ring 3, when pack into stack shell 4 and when rotating to lower dead center of pot lid rotation, the inclined-plane of lower cover 1 end holds out against the sealing projection 10 on the bottleneck sealing ring 3, the function that play sealing like this, is incubated.Gap between inner bag and the stack shell 4 is that polyurethane foam is filled, and after the cholic assembling, irritates quantitative polyurethane foam liquid between gallbladder and stack shell in having finished, and then adopts the technology of spinning friction welding that outer bottom 7 and stack shell 5 are welded again.Stack shell 5 and tube are wedge mouth syndeton at the end 7, referring to Fig. 7, finishing cylindrical shell through the spinning friction welding installs, tube is provided with foaming exhaust air technique hole the end 7, wait the expanding foam solution complete reaction of injecting after, the polyurethane heat-insulation piece of generation will fill up the gap of inner bag and stack shell, can allow thermo jug reach the higher shock proof intensity and the heat-insulating property of raising thermo jug, foaming exhaust air technique hole relies on silently 8 shutoff, silently 8 with an end 7 between be provided with silently sealing ring 9, referring to Fig. 8.The top of cylindrical shell is provided with Hu Zui, and when the state that pot lid inverse time hour hands rotated to 90 ℃, the inclination thermo jug just can be poured out the liquid in the kettle smoothly, referring to Fig. 2.

When pot lid is outwarded winding fully, can conveniently carry out cleaning and sterilizing, and can pour the liquid that needs interpolation into, referring to Fig. 3.
