surface of the box body 10 via a buckle, and a bottom end of the
inner disc 21 is telescopic relative to the lower opening of the
accommodation cavity of the box body 10. The middle sleeve is in
bolt connection to the inner disc and seals the upper opening of
the inner disc, which is helpful to maintain the cosmetic quality
inside the disc for a long time. The design is efficient and
convenient.
[0025] In this embodiment, the box body 10 comprises a hollow
cylindrical base 100 and a flange 101 connected to a lower end of
the hollow cylindrical base 100. The flange 101 extends inwards
radially and is integrated with the hollow cylindrical base 100.
The accommodation cavity of the box body 10 is formed by the hollow
cylindrical base 100 and the flange 101.
[0026] The box cover 11 comprises a first side and a second side
opposite to the first side. The hollow cylindrical base 100
comprises a first outer side wall and a second outer side wall
opposite to the first outer side wall. The first side of the box
cover 11 is hinged on the first outer side wall of the hollow
cylindrical base 100. The second side of the box cover 11 is
provided with a first hook, the second outer side wall of the
hollow cylindrical base 100 is provided with a second hook
corresponding to the first hook; and the first hook cooperates with
the second hook in a fastening or unfastening way to fix and unfix
the box cover 11 and the box body 10.
[0027] Preferably, the first side of the box cover 11 is provided
with an L-shaped buckle 12. The L-shaped buckle 12 is elastic and
butts against the first outer side wall of the hollow cylindrical
base 100, that is to say, the L-shaped buckle 12 is capable of
elastically opening the box cover.
[0028] As an improvement, taking the state that the box cover 11
seals the upper opening of the accommodation cavity as a reference,
the box cover 11 comprises a mirror 13 facing the upper opening of
the accommodation cavity.
[0029] As an improvement, the middle sleeve 20 comprises a first
middle sleeve 201 and a second middle sleeve 202; taking the state
that the middle sleeve 20 seals the upper opening of the inner disk
as a reference, the first middle sleeve 201 comprises a first body
2010 in the shape of a circular plate. The edge of the first body
2010 extends away from (i.e., extending upwards) the opening of the
inner disc to form an extension unit 2011, and the outer side wall
of the extension unit 2011 extends radially outwards to form a
connection unit 2012. The second middle sleeve 202 comprises a
second body 2020 which is a hollow cylinder comprising upper and
lower openings, the outer wall of the second body 2020 extends
radially outwards and bends downwards to form a folding part 2021,
the inner wall of the second body 2020 extends radially inwards to
form a support part 2022; one side of the connection unit 2012 is
hinged to and integrated with one side of the folding part 2021.
The first body 2010 is flexibly disposed on the second body 2020 to
open or seal the upper opening of the second body 2020.
[0030] The inner disc 21 comprises a hollow cylindrical body 210
which comprises an upper opening and an outer side wall. The cavity
of the inner disc is adapted to accommodate cosmetics. The outer
side wall of the hollow cylindrical body 210 is provided with male
threads, and the inner wall of the second body 2020 is provided
with female threads corresponding to the male threads.
[0031] As an improvement, taking a state that the first body 2010
seals the upper opening of the second body 2020 as a reference, the
outer side wall of the extension unit 2011 extends towards (i.e.,
extends downwards) the support part 2022 to form two coaxial first
airtight strips 2013, the side wall of the support part 2022
protrudes towards (i.e., extends upwards) the extension unit 2011
to form a second airtight strip 2023. The second airtight strip
2023 is located between the two coaxial first airtight strips 2013;
one of the two coaxial first airtight strips 2013 is attached to
the second airtight strip 2023, and the other coaxial first
airtight strip 2013 is attached to the inner wall of the second
body 2020.
[0032] The inner wall of the second body 2020 is provided with a
plurality of airtight ribs 22 between the support part 2022 and the
female threads. On one hand, the first airtight strips 2013 and the
second airtight strip 2023 greatly improve the sealing effect of
the first middle sleeve and the second middle sleeve; on the other
hand, the plurality of airtight ribs greatly improves the sealing
effect of the second body and the inner disc. The double airtight
structure greatly improves the sealing effect of the disc
assembly.
[0033] As an improvement, the middle sleeve 20 is connected to the
inner wall of the box body via a fastener. Specifically, the inner
side wall of the hollow cylindrical base 100 comprises a
depression. The outer side wall of the folding part 2021 protrudes
radially outwards towards the hollow cylindrical base 100 to form
two convex hulls 2024 disposed up-and-down. The radial width (the
radial width is the radial extension width of the convex hulls
along the base) of a lower one of the two convex hulls is less than
that of the upper one of the two convex hulls. The lower one of the
two convex hulls is inserted in the depression of the hollow
cylindrical base 100, and the upper one of the two convex hulls is
supported by the upper surface of the hollow cylindrical base
100.
[0034] As an improvement, the outer bottom wall of the hollow
cylindrical body 210 is sunken to form a containing groove 211 for
accommodating a power source. By placing a finger or coin in the
containing groove, the user can drive the hollow cylindrical body
to rotate in or out relative to the accommodation cavity. In
addition, the upper end of the inner wall of the hollow cylindrical
body 210 protrudes radially inwards to form a convex edge 212. Take
the state that the middle sleeve 20 seals the upper opening of the
hollow cylindrical body 210 as a reference, the convex edge 212
abuts against the support part 2022.
[0035] As an improvement, the outer side wall of the hollow
cylindrical body 210 is provided with a circumferential friction
band 213 below the male threads.
[0036] The replaceable air cushion powder box as described in the
disclosure can be used with the following two operation modes: one
is that the inner disc 21 is directly rotated out of the
accommodation cavity for use; the other is that, first, open the
box cover 11, and then rotate the inner disc 21 together with the
middle sleeve 20 out of the accommodation cavity, rotate and
separate the inner disc 21 from the middle sleeve 20 for use.
[0037] It will be obvious to those skilled in the art that changes
and modifications may be made, and therefore, the aim in the
appended claims is to cover all such changes and modifications.
