[0004] The invention provides a vacuum container, a cover body of the vacuum container and a combination of the vacuum container. The structure of the cover body of the vacuum container can have the functions of pressing exhaust and exhausting with an air extraction tool, so as to overcome the inability of the existing vacuum container to supply air. Users can choose to suck out the gas in the accommodating space of the vacuum container by pressing and / or using a suction tool according to their needs, and the structural design of the cover takes into account the convenience of pressing and the structural strength of the cover

Embodiment Construction
[0024] see figure 1 , which is an exploded view of an embodiment of the vacuum container combination of the present invention. like figure 1 As shown, the vacuum container assembly 1 includes a vacuum container 10 and an air extraction tool 13 . The vacuum container 10 includes a box body 11 and a cover body 12, the box body 11 has an upper edge 111, the cover body 12 and the box body 11 jointly define an accommodating space 14, and the cover body 12 includes a first part 121, a second part 122, The third part 123 and the air valve 124 . The first part 121 can accommodate the upper edge 111 of the box body 11, the second part 122 can withstand an external force F1 to produce deformation and return to the original shape when the external force is removed, and the third part 123 and the first part 121 together surround the second part 122, And the air valve 124 is disposed on the third part 123 . The suction tool 13 includes an opening 130 that substantially cooperates with ...

The invention involves a vacuum container, its cover and vacuum container combination.The vacuum container combination includes a vacuum container and exhaust tool.The vacuum container includes the box body and the lid.Part of the external forces can be degraded and the original form is recovered when the external force is removed. The third part and the first part are surrounded by the second part and have air valves.The gas drawing tool includes the opening, which cooperates with the third part of the cover body. The third part of the cover body is compared to the thickness T2 in the second part than the thickness of the second part. T1 (T2 / T1)1.1.The gas of the capacity of the capacity is exported by the second part of the external force and / or the gas valve to drive the air valve to discharge the capacity of the capacity from the third part.
Description
technical field [0001] The present invention relates to a vacuum container, its cover and vacuum container combination, in particular to a vacuum container which can selectively make the accommodating space under negative pressure through pressing and / or suction tools, the cover and the vacuum container Vacuum container set. Background technique [0002] At present, there are vacuum containers that can be exhausted by additional tools or objects to make the internal storage space negative pressure to store items, such as the following patents: EP1714910A1, CN2406951Y, US20120006853A1, US7246555B2, CN200620138824.6 and US5651470. The pumping structure of the aforementioned vacuum container is relatively complicated, and is operated with additional tools, for example: patents CN2406951Y, US7246555B2, and CN200620138824.6. If the user does not have the tool at hand, the vacuum container cannot be brought to a negative pressure state. [0003] In order to solve the above probl...
