Description
Technical Field
The utility model belongs to the technical field of plastic packaging container, a high leakproofness ability's packing jar is related to.
Background
The plastic packaging can for packaging biscuits, preserves, candies and other foods needs a long storage period after being opened, otherwise the quality of the foods is affected.
Present packing jar generally adopts and sets up soft gasket at the lid top and realize jar body and the sealed between the lid, and the sealed effect of this kind of seal structure is direct to be relevant with the degree of screwing of lid, and the user needs great strength to screw it, also more arduous when uncapping, influences consumer experience.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the above-mentioned problem that exists to current technique, provide a high leakproofness ability's packing jar, the utility model aims to solve the technical problem how improve the leakproofness ability of packing jar.
The purpose of the utility model can be realized by the following technical proposal: the packaging tin with high sealing performance is characterized by comprising a tin body and a cover body, wherein the upper end of the tin body is provided with a threaded joint, and the upper end of the tin body is provided with a first sealing surface vertical to the threaded joint; the inner wall of the top of the cover body is provided with a plurality of soft pressing strips, the inner wall of the cover body is provided with an internal thread corresponding to the threaded joint, a pressing gasket is arranged between the internal thread and the pressing strips, the lower surface of the pressing gasket is provided with an annular step surface, the step surface is positioned at the outer edge of the pressing gasket and corresponds to the upper end surface of the threaded joint, a second sealing surface perpendicular to the step surface is formed on the pressing gasket, and the second sealing surface is matched with the inner wall surface of the threaded joint.
The pressing strip is a protruding structure integrated with the cover body, a certain buffer space of a pressing gasket can be provided, after the cover body is connected with the tank body, the sealing between the upper end face of the threaded joint and the pressing gasket can be ensured without large screwing force, the inner side wall of the cover body, the step face and the second sealing face are surrounded and sealed by three faces of the upper end face of the threaded joint, the outer side face and the inner side face, and the sealing effect is good.
The first seal seals between lid lower extreme and the jar body, realizes multiple sealed, and sealed effect is better.
In the above packaging can with high sealing performance, a boss is arranged at the outer edge of the lower end of the cover body, the lower end of the cover body is connected with a sealing sheet with a lower end inclined outwards, the sealing sheet is annular, and the lower end of the sealing sheet can be located between the first sealing surface and the boss after the cover body and the can body are connected.
In order to improve the sealing effect, especially the sealing to dust, moisture, set up the gasket at first sealed face department, this gasket can be through warping in the process that lid and jar body compress tightly, makes the angle that the gasket lower extreme leaned out bigger, until keeping straight with first sealed.

Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in figure 1, the packaging can comprises a can body 1 and a cover body 2, wherein the upper end of the can body 1 is provided with a threaded joint 3, and the upper end of the can body 1 is provided with a first sealing surface 4 vertical to the threaded joint 3; the inner wall of the top of the cover body 2 is provided with a plurality of soft pressing strips 61, the inner wall of the cover body 2 is provided with an internal thread 5 corresponding to the threaded joint 3, a pressing gasket 62 is arranged between the internal thread 5 and the pressing strips 61, the lower surface of the pressing gasket 62 is provided with an annular step surface 63, the step surface 63 is positioned at the outer edge of the pressing gasket 62, the step surface 63 corresponds to the upper end surface of the threaded joint 3, a second sealing surface 64 perpendicular to the step surface 63 is formed on the pressing gasket 62, and the second sealing surface 64 is matched with the inner wall surface of the threaded joint 3.
The pressing strip 61 is a protruding structure integrated with the cover body 2, and can provide a certain buffer space for the pressing gasket 62, after the cover body 2 is connected with the tank body 1, the sealing between the upper end surface of the threaded joint 3 and the pressing gasket 62 can be ensured without large screwing force, the surrounding and sealing of the upper end surface, the outer side surface and the inner side surface of the threaded joint 3 are formed among the inner side wall of the cover body 2, the step surface 63 and the second sealing surface 64, and the sealing effect is good.
The first seal seals between the lower end of the cover body 2 and the tank body 1, so that multiple sealing is realized, and the sealing effect is better.
The outer fringe department of the lower extreme of lid 2 has a boss 7, and the lower extreme of lid 2 is connected with the gasket 8 that the lower end leaned out, and gasket 8 is the annular, and the lower extreme of gasket 8 can be in between first sealed face 4 and the boss 7 after lid 2 and jar body 1 are connected. In order to improve the sealing effect, in particular to the sealing of dust and moisture, a sealing sheet 8 is arranged at the first sealing surface 4, and the sealing sheet 8 can be deformed in the process of pressing the cover body 2 and the can body 1 to enable the lower end of the sealing sheet 8 to be inclined outwards at a larger angle until the sealing sheet is kept flat and straight with the first sealing.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
