Description
Technical field
The utility model relates to the jar of the container that is used for the contain fluid chemical, particularly a kind of chemical tank and chews lid.
Background technology
Chemical tank is a kind of container commonly used that holds liquid chemical raw material or manufactured product.Because the attribute and the characteristics of liquid chemical product or raw material, the leak tightness of container are one of necessary conditions that guarantees safety, making things convenient for the user to open better also is the aspect that manufacturer pays attention to.In prior art, connection and seal form that the jar of chemical tank is chewed lid have so several structures, and the one, adopt seal with screwed joint, its shortcoming is the manufacturing cost height, is unfavorable for automatic encapsulation; The 2nd, the form that adopts plastic plug to chew, shortcoming is that leak tightness is poor; The 3rd, adopt the pressure-lift cover, its structure is to utilize a plurality of elastic claw crampings that jar chews the lid periphery on jar is chewed, although use very conveniently, has relatively high expectations but have quality of fit, cost increases, and is unfavorable for the shortcoming of encapsulation automatically again.The weak point that these three kinds of structures also exist jointly is exactly that jar to chew lid be not disposable use, is difficult to prevent that the lawless person from utilizing the chemical tank of having used to be reloaded into counterfeit and shoddy goods and selling and make a profit.
The inventor is in order to solve above shortcoming with not enough, once designed a kind of chemical tank (Chinese patent ZL982432615 number) of chewing lid with the disposable top-pop jar and solved the problems referred to above.But it is complicated also to exist technology, and particularly jar is chewed and cover the easy-to-draw ear in periphery bottom and be difficult for neatly tearing, and user's unlatching is not a problem very easily.
Summary of the invention
The purpose of this utility model is to provide a kind of defective that can solve aforementioned three kinds of structures, and simple in structure, good airproof performance that again can more convenient unlatching, sealed cans and the good a kind of disposable top-pop that is used for chemical tank of antifalsification are chewed lid automatically.
The technical scheme that realizes the utility model purpose is:
The utility model comprises jar chews lid, enclosing cover and inner sealing lid, covers outward and is provided with pull-tab, and the enclosing cover crimping is wrapped in jar and chews and cover, and inner sealing lid is embedded in jar and chews in the lid on the ring-shaped step.
Inner sealing lid is provided with pull-tab.
Jar is chewed the lid middle part and is established seal ring, and the bottom is the inwall vertical surface, and outer wall is the inclined-plane, and equidistantly is provided with 5-8 bar elasticity notch.Capping is provided with a circle tear line outside, is provided with 10～20 protection points on tear line equably.
Enclosing cover and inner sealing lid all adopt thin aluminum sheet to make.
The utility model is safe and reliable owing to the structure that adopts Double layer lid has, good airproof performance, the automatic encapsulation when being convenient to produce, in cover the pull-tab of establishing and be beneficial to again that the user is convenient to open, its antifalsification is better, prevent that effectively the lawless person from utilizing former bottle can counterfeit and shoddy goods harm customer again, greatly improves the safe reliability of chemical tank.
Be described further with regard to structure of the present utility model and condition of service below in conjunction with accompanying drawing.
Description of drawings
Accompanying drawing 1 is the utility model generalized section;
Accompanying drawing 2 is the enclosing cover schematic top plan view;
Accompanying drawing 3 is chewed the main scheme drawing of looking of lid for jar;
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, jar chews that to cover 1 be to be made of plastics, and top is enclosing cover 2, and enclosing cover 2 is to be made by thin aluminum sheet, and thin aluminum sheet good-extensibility, intensity be low, be easy to tear.Enclosing cover 2 is provided with pull-tab 3; pull-tab 3 has neutral gear with enclosing cover 2 edges; pull-tab 3 is aluminium sheet materials with enclosing cover 2; good integrity; 2 of enclosing covers are gone up outer edge and partly are provided with a circle tear line 6; when opening enclosing cover 2 like this; tear pull-tab 3 and just can tear enclosing cover 2 along tear line 6 regular and equably; be provided with 10～20 protection points 7 along tear line 6 one circles; the effect of this protection point 7 is that the protection tearing port is evenly opened along tear line 6 one circles when tearing enclosing cover 2; being unlikely tear line 6 is stretched to outer rim or breaks; enclosing cover 2 is compressed by roll-pressing machine and is wrapped in jar and chews and cover on 1; outer rim to middle part seal ring 8 place's crimpings are wrapped, like this leak tightness compactness; safety can protect inner sealing lid 5 not to be extruded when inner sealing lid 5 is subjected to tank interior pressure.The pull-tab 10 that inner sealing lid 5 is provided with provides more convenience for the user opens chemical tank.Jar is chewed and cover the ring-shaped step 4 that 1 inwall middle part is provided with a circle projection, so that inner sealing lid 5 is set, when using chemical liquid, with after pull-tab 3 are drawn back capping above the enclosing cover 2, draws the pull-tab 10 that opens on the inner sealing lid 5 more earlier, just can easily open and jar pour out liquid.Jar chews that cover 1 interior ring-shaped step be vertical with lower wall surface, outer wall seal ring 8 is the inclined-plane and is provided with 5～8 elasticity notches 9 equally spacedly by circumference with the lower part jut, jut and chamfered portion and elasticity notch 9 are convenient to jar and are chewed lid flush fit when being installed in tank body, easilier when elasticity notch 9 also can make pouring liquid have all fallen.
