Background

Snacks (such as biscuits, nuts, preserves, etc.) are usually prepared in homes, and in order to prevent the snacks from being affected with moisture and mildewing, the snacks are usually placed in a sealed container such as a sealed can or a fresh food box to slow down the deterioration of the snacks. In the existing sealed can or fuse box, the sealing ring is usually arranged at the lower end of the cover, after the cover is closed with the can body, the upper opening end face of the can body is in sealing contact with the sealing ring, the cover and the tank body are not reliably clamped, the outer wall of the cover or the outer wall of the tank body is additionally provided with a turnover wing piece, the wing piece is provided with an inverted buckle, the inverted buckle is fastened by turning the wing piece, the structure is complex, the manufacture is troublesome, in addition, the lower end of the cover is provided with a boss, the outer wall of the boss is provided with a sealing ring, the sealing ring slightly protrudes out of the outer wall of the boss, when the cover is assembled with the tank body, the sealing ring is clamped into the inner wall of the tank body and is tightly and hermetically matched with the inner wall of the tank body, because the cross section of sealing washer is circular or oval, needs through the sealing washer chucking between lid and the jar body, consequently the sealing washer receives the extrusion for a long time, and easy ageing, deformation to influence sealing performance.

Disclosure of Invention

The utility model aims at overcoming the shortcoming that prior art exists, providing a simple structure, it is convenient to make, and sealing performance is good, non-deformable, long service life's seal pot's oblique gasket sealing mechanism.

The utility model discloses oblique gasket sealing mechanism of seal pot's technical scheme is: including a jar body and cover, the cover lower extreme contacts with jar body suitable for reading, the cover under system have annular flange, form the cavity between the annular flange, the system has the air vent in the flange, lower extreme outer wall system at the flange has punch holder and lower plate, form the clearance between punch holder outer wall and the internal wall of jar, form between upper and lower plate and press from both sides the groove, set up the gasket in pressing from both sides the groove, the gasket includes clamping part and sealing, the clamping part and the double-layered groove of gasket cooperate, after jar body is gone into to the cover card, the sealing of gasket and internal wall of jar and punch holder outer wall sealing contact.

the utility model discloses an oblique sealing sheet sealing mechanism of a sealing tank, which is mainly characterized in that an annular convex plate is arranged under a tank cover, an air vent is arranged in the convex plate, an upper clamping plate and a lower clamping plate are arranged on the outer wall of the lower end of the convex plate, a clamping groove is formed between the upper clamping plate and the lower clamping plate, a flat sheet sealing sheet is arranged in the clamping groove and is divided into a clamping part and a sealing part, wherein the clamping part is clamped into the clamping groove, the clamping groove plays a fixing role on the sealing sheet, the sealing part protrudes out of the clamping groove, the whole sealing sheet is softer and is easy to elastically deform due to a flat sheet structure, when the annular convex plate at the lower end of the tank cover is clamped into the tank body, the outer diameter of the sealing part of the sealing sheet is larger than the inner diameter of the upper opening part of the tank body, the sealing part extrudes the sealing part to enable the sealing part to be elastically deformed upwards, the outer wall of the sealing part is in, make and obtain sealed cooperation between jar body and the cover, and when the cover pushed down, the air of the internal portion of extrusion jar, this air is discharged to the external world through the gas vent, and after closed completely, the cover lower extreme obtains the second with the last port end face contact of the jar body and says sealedly, this simple structure, and it is convenient to make, and sealing performance is good, and flat flaky gasket extrudes repeatedly, non-deformable, long service life.

The utility model discloses oblique gasket sealing mechanism of seal pot, gasket arc slope upwards. Because the sealing portion that can be with the gasket upwards extrudees when the cover card is gone into jar body, makes its bending elastic deformation, consequently makes the gasket arc slope upwards directly, more is favorable to gasket bending elastic deformation. The convex plate is provided with one or more than one vent holes. Different numbers of vent holes can be arranged according to the requirement.

Detailed Description

the utility model relates to an oblique gasket sealing mechanism of seal pot, as shown in fig. 1-3, including jar body 1 and jar cover 2, the jar cover lower extreme contacts with jar body suitable for reading, jar cover 2 down the system have annular flange 3, form cavity 4 between the annular flange, the system has air vent 5 in the flange, the system has punch holder 6 and lower plate 7 at the lower extreme outer wall system of flange, form clearance 8 between punch holder outer wall and jar body 1 inner wall, form between upper and lower plate and press from both sides groove 9, set up gasket 10 in pressing from both sides the groove, the gasket includes chucking part 11 and sealing 12, the chucking part and the clamp groove 9 of gasket cooperate, after jar body 1 is gone into to jar cover 2 card, the sealing of gasket and jar body inner wall and punch holder 6 outer wall sealing contact. Mainly, an annular convex plate 3 is arranged below a tank cover 2, an air vent 5 is arranged in the convex plate, an upper clamping plate 6 and a lower clamping plate 7 are arranged on the outer wall of the lower end of the convex plate 3, a clamping groove 9 is formed between the upper clamping plate and the lower clamping plate, a flat sheet-shaped sealing sheet 10 is arranged in the clamping groove, the flat sheet-shaped sealing sheet is divided into a clamping part 11 and a sealing part 12, wherein the clamping part 11 is clamped in the clamping groove 9, the clamping groove fixes the sealing sheet 10, the sealing part protrudes out of the clamping groove, the whole sealing sheet is of a flat sheet-shaped structure, is relatively flexible and is easy to elastically deform, when the annular convex plate 3 at the lower end of the tank cover 2 is clamped in the tank body 1, the outer diameter of the sealing part 12 of the sealing sheet is larger than the inner diameter of the upper opening part of the tank body 1, the upper opening part of the tank body presses the sealing part 12 of the sealing sheet 10, so that the sealing part bends upwards and elastically deforms, make and obtain sealed cooperation between jar body 1 and cover 2, and when the cover pushed down, the air of the internal portion of extrusion jar, this air is discharged to the external world through gas vent 5, and after closed completely, the upper end face contact of the 2 lower extremes of cover and jar body 1 obtains the second and says sealedly, this simple structure, and it is convenient to make, and sealing performance is good, and flat flaky gasket 10 extrudes repeatedly, non-deformable, long service life. The sealing plate 10 is inclined upwards in an arc shape. Because the can cover 2 can press the sealing part 12 of the sealing sheet 10 upwards when being clamped into the can body 1, and the sealing sheet 10 is bent and elastically deformed, the sealing sheet 10 is directly made into an arc shape and inclines upwards, and the bending and elastic deformation of the sealing sheet is more facilitated. The convex plate 3 is provided with one or more than one vent holes 5. Different numbers of vent holes 5 can be provided as required.
