Abstract
The utility model discloses a negative pressure preservation box, and particularly relates to a circular preservation box capable of adopting negative pressure to improve preservation capacity, belonging to the field of a preservation box technology. The negative pressure preservation box consists of a box cover, an extract opening with a check valve, a seal ring and a box body. The negative pressure preservation box is characterized in that the extract opening with the check valve is formed on the circular box cover, the seal ring is arranged below the circular box cover, the circular box cover is covered on the circular box body and the circular box cover and the circular box body are sealed through the seal ring, so that foods needed to be preserved are placed in the box body during use; and the box cover is covered on the box body, air in the box body is extracted through either a manual sucking pump or an electronic sucking pump, and the negative pressure is formed in the box body. Therefore, the negative pressure preservation box achieves the aims that food flavors are not influenced and food preservation periods are prolonged, and practicability is good.
Description
Technical field
The utility model relates to a kind of negative-pressure fresh-keeping box, relates in particular to a kind of circular crisper that adopts negative pressure to improve preservativity, belongs to the crisper technical field.
Background technology
When food fresh keeping, fresh-keeping means commonly used are food to be put into refrigerator carry out fresh-keepingly, and the fresh keeping principle of refrigerator is with the food cooling, reduces the bacterial reproduction speed of food after the cooling, but alter easily flavor between the food in the refrigerator, therefore in refrigerator, use crisper.Water, temperature, air are the requisite environmental factors of bacterial reproduction, when reducing temperature, are reduced pressure in crisper inside, destroy the breeding environment of bacterium by the decompression means, are a kind of preservation methods of environmental protection.
Vacuum storage bag (vacuum compression bag) is widely used on market at present, and the bleeding point that check valve is arranged of vacuum storage bag is a kind of known technology, and the matching used manual suction pump of vacuum storage bag and miniature electric air extracting pump also are known technologies.
At present without a kind of circular crisper that adopts negative pressure to improve preservativity is arranged, the patent searching document is open without the new technical scheme of this technology, the utility model is by lid, the bleeding point that check valve is arranged, seal ring, box body forms, it is characterized in that circular box covers the bleeding point that leaves check valve, below circular lid, seal ring is housed, circular lid covers on round box, seal ring makes between circular lid and the round box and seals, the box body of during use required fresh-keeping food being packed into, at box body upper cover upper box cover, with manual suction pump or electronic air extracting pump air in the box body is taken away, make and form negative pressure in the box body, get final product, reach and do not alter flavor between the food, and prolong the purpose of food fresh keeping phase.
Summary of the invention
In order to overcome existing nothing a kind of deficiency that adopts negative pressure to improve the circular crisper of preservativity is arranged, the purpose of this utility model is for a kind of circular crisper that adopts negative pressure to improve preservativity is provided, this crisper simplicity of design, with low cost, easy to use, reach and do not alter flavor between the food, and prolong the purpose of food fresh keeping phase.
The technical scheme in the invention for solving the technical problem is: by lid, the bleeding point that check valve is arranged, seal ring, box body forms, it is characterized in that circular box covers the bleeding point that leaves check valve, below circular lid, seal ring is housed, circular lid covers on round box, seal ring makes between circular lid and the round box and seals, the box body of during use required fresh-keeping food being packed into, at box body upper cover upper box cover, with manual suction pump or electronic air extracting pump air in the box body is taken away, make and form negative pressure in the box body, get final product, reach and do not alter flavor between the food, and prolong the purpose of food fresh keeping phase.
The beneficial effects of the utility model are simplicity of design, and are with low cost, easy to use, reach and do not alter flavor between the food, and prolong the purpose of food fresh keeping phase, and practicality is large.
