Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a kind of daily commodity,
and more specifically relates to a vacuumized container box.
[0002] At present, box-shaped containers are very common in our
daily life. However, many existing box-shaped containers could not
be vacuumized. Articles stored inside such containers could easily
develop moulds and turn bad because water exists in the air inside
the containers. Nowadays, vacuumized bags have been developed for
storing clothes. However, the existing vacuumized bags could be
easily damaged, and they are also inconvenient to use because air
pumps are required for vacuumization. Furthermore, such vacuumized
bags could not be used for storing other items such as food items.
Vacuumized containers are available nowadays but they are
inconvenient to use or they are not good at discharging air.
BRIEF SUMMARY OF THE INVENTION
[0003] In view of the technical problems such as poor air
discharging effect and inconvenient air discharging operation now
present in the existing vacuumized containers, the present
invention provides a portable vacuumized container box which is
efficient in discharging air and which is easy to use.
[0004] The present invention is attained by the following technical
proposal:
[0005] A portable vacuumized container box comprises a box body
having a cavity; the box body opens at its upper end; a top cover
capable of fastening with the box body is provided at the upper end
of the box body; air inlet hole and air outlet hole are disposed on
the top cover; air inlet device is disposed on the air inlet hole;
air outlet device is disposed on the air outlet hole; the air
outlet device comprises an air outlet piston, a piston fixing
cover, and an air outlet valve coordinating with the air outlet
piston to discharge air.
[0006] Further, to facilitate air discharge, a pull ring is
provided at an upper end of the air outlet piston for easier
application of force; the air outlet valve is disposed at a bottom
end of the air outlet hole; the air inlet device is an air inlet
valve disposed on the air inlet hole; the air outlet valve and the
air inlet valve are both silicon valves. Silicon valves are good at
their sealing ability and resilience. To further improve air
discharging efficiency, a piston sealing ring is disposed on the
air outlet piston. In order that the top cover is formed integrally
as a whole with good aesthetic appearance, a recessed hole is
provided on the top cover; the piston fixing cover is fitted in the
recessed hole; the air outlet hole and the air inlet hole are
disposed at a bottom end of the recessed hole. The pull ring is
connected with the upper end of the air outlet piston via a pin so
that the pull ring can be freely pulled up and pressed down. A seal
ring is provided at a position where the top cover and the box body
are fastened with each other in order to improve the sealing
ability of the container box; peripheries of the top cover are
provided with fasteners for fastening the box body.
[0007] As compared with existing prior arts, the portable
vacuumized container box of the present invention is provided with
the air outlet device on the air outlet hole and the air inlet
device on the air inlet hole; the air outlet device comprises the
air outlet piston, the piston fixing cover, and the air outlet
valve coordinating with the air outlet piston to discharge air; the
pull ring is provided at the upper end of the air outlet piston for
easier application of force; when discharging air, pull up and
press down the pull ring to discharge air through the air outlet
valve. To open the top cover, simply squeeze the air inlet valve to
let air outside the container box flow into the container box
through the periphery of the air inlet valve. When air pressure
inside and outside the container box is equal, the top cover can be
opened. The air outlet device and the air inlet device are
integrally provided in the box body; extra air outlet device is
therefore not required. Also, air can be discharged and the
container box can be vacuumized by simply pulling up and pressing
down the pull ring; therefore the present invention is convenient
to use and has high air discharging effect. Since a seal ring is
provided at the position where the top cover is fastened with the
box body to further improve the sealing ability of the container
box, the present invention is efficient, durable and very easy to
use.

DETAILED DESCRIPTION OF THE INVENTION
[0016] The present invention is further explained below with
reference to figures and the embodiments.
Embodiment 1
[0017] As shown in FIGS. 1 and 3, a portable vacuumized container
box comprises a box body 1 having a cavity; the box body 1 opens at
its upper end; a top cover 2 capable of fastening with the box body
1 is provided at the upper end of the box body 1; air inlet hole 4
and air outlet hole 3 are disposed on the top cover 2; air inlet
device is disposed on the air inlet hole 4; air outlet device is
disposed on the air outlet hole 3; the air outlet device comprises
an air outlet piston 5, a piston fixing cover 6, and an air outlet
valve 7 coordinating with the air outlet piston 5 to discharge air;
a pull ring 8 is provided at an upper end of the air outlet piston
5 for easier application of force; the air outlet valve 7 is
disposed at a bottom end of the air outlet hole 3; the air inlet
device is an air inlet valve 9 disposed on the air inlet hole 4;
the air outlet valve 7 and the air inlet valve 9 are both silicon
valves. A piston sealing ring 10 is disposed on the air outlet
piston 5; the pull ring 8 is connected with the upper end of the
air outlet piston 5 via a pin; a seal ring 12 is provided at a
position where the top cover 2 and the box body 1 are fastened with
each other; peripheries of the top cover 2 are provided with
fasteners 13 for fastening the box body 1.
Embodiment 2
[0018] As shown in FIGS. 2, 4, 5 and 6, a second embodiment is
disclosed on the basis of the embodiment 1 as described above; a
recessed hole 11 is provided on the top cover 2; the piston fixing
cover 6 is fitted in the recessed hole 11; the air outlet hole 3
and the air inlet hole 4 are disposed at a bottom end of the
recessed hole 11. The top cover 2 of embodiment 2 has better
aesthetic appearance as it is made with other components thereon
integrally provided within its outer contour.
[0019] Use of the container box of present invention according to
the two embodiments as described above is detailed as follows: When
the pull ring 8 is pulled up, the air outlet piston 5 is also
pulled up; air inside the container box rises up; the air outlet
valve 7 at a bottom end of the air outlet hole 3 rises up and
deforms; the air inside the container box is discharged through a
gap between the air outlet piston 5 and the air outlet hole 3; when
the pull ring 8 is pressed down, the air outlet piston 5 is also
pressed downwardly; the air outlet valve 7 at the bottom end of the
air outlet hole 3 returns to its original shape, and air outside
the container box cannot enter into the cavity of the container
box. The above operation is considered a complete air discharging
operation of the container box. Repeat the above operation until it
is very difficult to pull up the air outlet piston 5, or cover and
body is slightly shrinked inward. At the time when container box is
visually shrinked inward, air inside the box has been pumped out
and the container box is vacuumized.
[0020] To open the top cover 2, simply squeeze the air inlet valve
9 to deform the air inlet valve 9; air outside the container box
enters the air inlet hole 4 through periphery of the air inlet
valve 9 and then enters the container box; when air pressure inside
and outside the container box is equal, the top cover 2 can be
opened.
[0021] The air outlet device and the air inlet device are
integrally provided in the box body 1; extra air outlet device is
therefore not required. The present invention is convenient to use
and has high air discharging effect.
[0022] The above description is intended to be the preferred
embodiments of the present invention. Any obvious modification and
replacement which do not deviate from the inventive concept of the
present invention should fall within the scope of protection of the
present invention.
