Description
Technical Field
The utility model belongs to the technical field of the food package jar, concretely relates to dampproofing cover and have dampproofing jar of this dampproofing cover.
Background
The salt is the first of seven, and the common salt is not only an indispensable seasoning in human diet, but also an indispensable substance component in human body. The salt is salty in taste and cold in nature, enters stomach, kidney and large and small intestine channels, and has the functions of clearing away heat and toxic materials, cooling blood and moistening dryness, nourishing kidney and relaxing bowels, killing parasites and diminishing inflammation, and promoting vomiting and relieving diarrhea. The salt contains sodium chloride as main ingredient, and also contains impurities such as magnesium chloride and magnesium sulfate. In general, sodium chloride is more hygroscopic, and impurities such as magnesium chloride and magnesium sulfate accelerate the process. Therefore, the phenomenon of salt moisture absorption and caking usually occurs during the shelf life storage or when people use salt.
In order to avoid salt moisture absorption and caking, the applicant improves the existing salt packaging can, for example, a salt moisture-proof can is opened in the Chinese patent (application number 202020040552.6), and comprises a can body, a can cover and a closed moisture-proof interlayer for accommodating a drying agent, wherein the moisture-proof interlayer is arranged around the inner wall of a can opening of the can body; the inner wall of the interlayer of the moisture-proof interlayer is provided with a circle of annular breathable films so that air at the opening of the tank can enter the cavity of the moisture-proof interlayer through the breathable films. This dampproofing jar can prevent to store the salt moisture absorption caking in the jar to do benefit to the long-term storage of salt, and to frequently uncapping get salt from the jar in or forget for a long time when covering the cover, also can effectively slow down the moisture absorption speed of salt. For another example, chinese patent application No. 202020037600.6 discloses a moisture-proof can for edible seasoning salt, which comprises a can body, a can cover, and a moisture-proof wall ring arranged along the inner wall of the can opening of the can body and in an annular shape; the moisture-proof wall ring is internally provided with an accommodating cavity which can be filled with a desiccant, and the surface of the moisture-proof wall ring is provided with air holes with the diameter of 0.05-0.1 mm, so that air at the opening of the tank can enter the accommodating cavity of the moisture-proof wall ring through the air holes. This dampproofing jar of edible salt of flavouring can prevent to store the edible salt of flavouring moisture absorption caking in the jar to do benefit to the long-term storage of edible salt of flavouring, and get salt or forget for a long time when covering the cover to frequently uncapping from the jar in, also can effectively slow down the moisture absorption speed of edible salt of flavouring.
The two improved technical solutions are mainly different in that one of the cavities containing the moisture-proof agent is fixed, while the other is detachable, but they are both arranged in the tank body; for high-grade salt, in order to improve the beauty of product package, a glass packaging tank is generally adopted, and if a cavity containing a moisture-proof agent is arranged in a glass tank body, the structure can be seen from the outside, which affects the beauty of the product package.
Based on this, the applicant discloses in another patent technical scheme (application number 202120502766.5) a salt dampproofing jar convenient to change drier, including a jar body, cover, the bottom that cover and jar body lid closed is opened there is the drier recess, the notch of drier recess is provided with the detachable capping, evenly laid the bleeder vent that runs through the capping on the capping, the capping fits and encloses the appearance intracavity that closes formation in the drier recess and be provided with the dry piece of fibre. The utility model discloses salt dampproofing jar not only takes the salt convenient, and adopts the dry piece of fibre as the drier, and the drier is changed conveniently, and the drier can not sneak into in the salt yet and produce the potential safety hazard.
In the technical scheme, although the drying agent groove is arranged on the tank cover, water vapor in the tank is absorbed by the fiber drying sheet through the air holes, in order to prevent salt from permeating into the drying agent groove, the hole diameter of the air holes cannot be too large, and the air holes are easily blocked after a long time, so that the circulation of the water vapor is limited; in addition, because the fiber drying sheet is a regular rectangular sheet, although the fiber drying sheet is convenient to replace, the fiber drying sheet generally does not have a curved surface shape, and the adsorption efficiency of water vapor is low; therefore, in practical applications, the moisture-proof effect of the technical solution is not ideal.
