ECO-FRIENDLY PUMPING DEVICE USING THE PRINCIPLE OF
VACUUM
CROSS-REFERENCE TO RELATED PATENT APPLICATION
This application claims the benefit of priority to China Patent Application
No. 201810992347.7, filed on August 29, 2018.
FIELD OF THE DISCLOSURE
The present disclosure relates to a pumping device, and more particularly to
an eco-friendly pumping device using the principle of vacuum.
BACKGROUND OF THE DISCLOSURE
Everyday necessities such as shampoo, shower gel, and dishwashing liquid
are mostly bottled, and have a dispensing head disposed over the bottle
opening to
draw out the fluid in the bottle by pressing for use. While such a way of
extracting
the fluid is convenient, some of the fluid will still remain at a bottom of
the bottle
and cannot be used completely even if the consumer would like to draw out the
fluid
material. In addition, the bottle and the dispensing head are typically
discarded
without recycling resulting in waste. Further, the fluid remaining in the
bottle can
also seriously halm the environment.
With the recent rise of environmental awareness, how such materials can be
reused has become an important issue. Therefore, refill packages for everyday
necessities such as shampoo, shower gel, and dishwashing liquid can now be
found
on the market to reduce waste of the containers. However, the refilling
process, i.e.
transferring the replacement material in the refill packages into the bottle,
requires a
lot of work and time, and the fluid may easily smear onto the hands making a
mess
everywhere and even haiming the environment when the fluid of the refill
packages
is transferred into the bottle. This results in a lot of water being needed to
wash
away the smeared fluid, which can be quite inconvenient. Furthermore, the
refill
packages may also contain residual fluid becoming hard to recycle, or may
pollute

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS
The present disclosure will become apparent from the following description
of the embodiment taken in conjunction with the following drawings that are
intended as illustrative only, but not used for limiting the scope of the
present
disclosure.
Reference is made to FIG. la to FIG. 4. The present disclosure provides an
eco-friendly pumping device using the principle of vacuum, which includes a
press
pumping unit 1, a replaceable soft bag 2 and a bottle 3.
The press pumping unit 1 includes a dispensing head 11, a pump cylinder 12
and a duct 13. The dispensing head 11 is connected to a top end of the pump
cylinder
12. The duct 13 is connected to a bottom end of the pump cylinder 12. The pump
cylinder 12 can be cylinder-shaped. The duct 13 is a hollow pipe. When the
dispensing head 11 is pressed, the pump cylinder 12 provides a drawing force.
Therefore, the duct 13 can suck up a fluid material, and the fluid material
can pass
through the duct 13, the pump cylinder 12 and the dispensing head 11, to then
be
outputted outward.
A cap 14 is disposed around a top end of the pump cylinder 12. The cap 14
has a first screw thread 141. The first screw thread 141 can be an inner
thread or
female thread to allow the cap 14 to be screwed to the bottle 3. The press
pumping

unit 1 is a device used to pump a fluid material by pressing, whose structure
can be
available in the conventional art, and is not emphasized in the present
disclosure. In
addition, the structure of the press pumping unit 1 of the present disclosure
is not
limited.
The pump cylinder 12 is formed with at least one first fastening portion 15,
which can be used to fasten to at least one second fastening portion 23 of the
replaceable soft bag 2. In this embodiment, the first fastening portion 15 is
formed
on an outer surface of the pump cylinder 12. The first fastening portion 15
can be a
wedging protrusion, and can preferably be more than one, for example, two or
three.
The replaceable soft bag 2 has a flexible bag body 21. The flexible bag body
21 is made of waterproof and flexible material. The flexible bag body 21 has
an
opening part 22 formed on a top end thereof. The opening part 22 is a hollow
cylinder. The opening part 22 is connected to an interior of the flexible bag
body
21. The flexible bag body 21 can be filled with fluid material, such as
shampoo,
shower gel and dishwashing liquid. The kind of the fluid material is not
limited.
Before the replaceable soft bag 2 is assembled to the press pumping unit 1 and
the
bottle 3, the opening part 22 can be sealed with a sealing lid or sealing
plate (not
shown), so as to prevent the fluid material in the flexible bag body 21 from
flowing
out and so that the flexible bag body 21 can be conveniently transported and
stored.
The opening part 22 is formed with at least one second fastening portion 23,
which can be used to fasten to the first fastening portion 15 of the press
pumping
unit 1. In this embodiment, the second fastening portion 23 is formed on an
inner
surface of the opening part 22. The second fastening portion 23 can be a
wedging
groove, and can preferably be more than one, for example, two or three. The
second
fastening portion 23 of this embodiment has a first groove 231 and a second
groove
232. The first groove 231 extends downward from an upper end of the opening
part
22, and one end of the second groove 232 is connected to a lower end of the
first
groove 231. The second groove 232 extends along a circumferential direction of
the
opening part 22, and is perpendicular to the first groove 231, so that the
second
fastening portion 23 is formed as an L-shaped wedging groove (as shown in FIG.
6

la).
The replaceable soft bag 2 can be connected to the press pumping unit 1 in a
fastening manner. In other words, the pump cylinder 12 of the press pumping
unit
1 can be inserted in the opening part 22 of the replaceable soft bag 2. Then,
the first
fastening portion 15 can move downward along the first groove 231 of the
second
fastening portion 23. When the first fastening portion 15 moves to a lower
endpoint
of the first groove 231, the press pumping unit 1 and replaceable soft bag 2
are
rotatable, and the first fastening portion 15 enters the second groove 232.
Finally,
the first fastening portion 15 moves to another endpoint of the second groove
232
and is fixed. The replaceable soft bag 2 is therefore fastened and fixed to
the press
pumping unit 1, and the duct 13 enters into the replaceable soft bag 2. The
lower
end of the duct 13 is close to a bottom wall of the replaceable soft bag 2.
Preferably,
a gap G between the bottom end of the duct 13 and the bottom wall of the
replaceable
soft bag 2 is lmm to 10mm.
However, the first fastening portion 15 and the second fastening portion 23
of the present disclosure are not limited thereto, and can be other available
fastening
structures. For example, the first fastening portion 15 can be an L-shaped
wedging
groove, and the second fastening portion 23 can be a wedging protrusion, so
that the
first fastening portion 15 and second fastening portion 23 can be fastened to
each
other (as shown in FIG. lb). The first fastening portion 15 can be various
protruding
or concave structures, and the second fastening portion 23 can be various
concave
or protruding structures correspondingly, which allows the first fastening
portion 15
and the second fastening portion 23 to be fastened to each other. The first
fastening
portion 15 could be with a screw thread structure, and the second fastening
portion
23 could be with a screw thread structure, both of which are the concave or
protruding structures allowing the first fastening portion 15 and the second
fastening
portion 23 to be fastened to each other, as shown in FIG. lc.
The replaceable soft bag 2 is fastened and connected to the press pumping
unit 1. The pump cylinder 12 of the press pumping unit 1 is inserted in the
opening
part 22 of the replaceable soft bag 2, and the opening part 22 of the
replaceable soft
7
Date Recue/Date Received 2022-06-07

2022-06-07
bag 2 can be sealed, so that an interior of the replaceable soft bag 2 forms a
closed
space 24. The interior of the replaceable soft bag 2 can therefore be in a
negative
pressure state because of the vacuum effect, and the shape and the inner
volume of
the flexible bag body 21 shrink as the time of use and amount of use increase.
When
the dispensing head 11 of the press pumping unit 1 is pressed, the pumping
force
produced by the pump cylinder 12 can cause the interior of the replaceable
soft bag
2 to be in a negative pressure state, so that the fluid material can be drawn
out through
the duct 13.
To increase the sealing effectiveness of the closed space 24 of the
replaceable
soft bag 2, at least one first sealing element 25 can be disposed between the
opening
part 22 of the replaceable soft bag 2 and the pump cylinder 12 of the press
pumping
unit 1. The first sealing element 25 is disposed between an inner surface of
the
opening part 22 of the replaceable soft bag 2 and an outer surface of the pump
cylinder 12 of the press pumping unit 1, so that the opening part 22 of the
replaceable
soft bag 2 tightly contacts the pump cylinder 12 of the press pumping unit 1,
which
can prevent external air from entering the closed space 24 of the replaceable
soft bag
2. The closed space 24 of the replaceable soft bag 2 can be maintained in a
state of
negative pressure during use. The press pumping unit 1 is directly assembled
with
the replaceable soft bag 2, so as to provide a better airtightness between the
press
pumping unit 1 and replaceable soft bag 2.
The bottle 3 is a hollow container for receiving the replaceable soft bag 2. A
top end of the bottle 3 has a bottle lip 31, and the bottle lip 31 is opened.
The bottle
lip 31 is fluidly connected with the interior of the bottle 3. The bottle lip
31 has a
second screw thread 311, and the second screw thread 311 can be an outer
thread.
The first screw thread 141 and the second screw thread 311 are screwed
together, so
that the cap 14 can be connected to the bottle lip 31 of the bottle 3 in a
screwing
manner. According to another embodiment of the present disclosure, the cap 14
can
be connected to the bottle lip 31 of the bottle 3 in a wedging manner.
The replaceable soft bag 2 is disposed in the bottle 3. For allowing the
replaceable soft bag 2 to be conveniently put into the bottle 3, the bottle 3
of this
8
Date Recue/Date Received 2022-06-07

2022-06-07
embodiment has a two-piece design. In other words, the bottle 3 has an upper
housing 32 and a lower housing 33. The upper housing 32 and the lower housing
33
can be assembled together in a wedging or screwing manner, so that the
replaceable
soft bag 2 can be easily disposed in the bottle 3.
In addition, the replaceable soft bag 2 has at least one second sealing
element
26 which is disposed on the opening part 22. The second sealing element 26 is
disposed among the opening part 22 of the replaceable soft bag 2, the pump
cylinder
12 of the press pumping unit 1, the cap 14, and the bottle lip 31 of the
bottle 3. The
second sealing element 26 can cooperate with the first sealing element 25 to
provide
a double sealing effect, so as to maintain the closed space 24 of the
replaceable soft
bag 2 in a state of negative pressure during use.
According to the eco-friendly pumping device of the present disclosure, an
interior of the replaceable soft bag 2 can be squeezed automatically by an
external
air pressure outside the replaceable soft bag 2 because of the vacuum effect.
In other
words, when the dispensing head 11 of the press pumping unit 1 is pressed, the
interior of the replaceable soft bag 2 is vacuumed and the press pumping unit
1 does
not resupply air, so as to draw out the fluid material in the replaceable soft
bag 2 by
a vacuum principle. When the fluid material in the replaceable soft bag 2 is
emptied,
it can be replaced with another new replaceable soft bag 2 filled with fluid
material
for continuous use.
In conclusion, the press pumping unit 1 and the bottle 3 of the present
disclosure are reusable, and do not cause environmental issues. In addition,
the force
of gravity causes the fluid material to fall toward the inner bottom of the
replaceable
soft bag 2, and the vacuum principle causes the fluid material to be outputted
through
the duct 13 so that no residual fluid material remains in the replaceable soft
bag 2.
The fluid material can be used completely (as shown in FIG. 4) without any
being
wasted, and does not cause an environmental burden.
Further, according to the present disclosure, the fluid material in the
replaceable soft bag 2 does not need to be poured into the bottle 3, and the
fluid
material does not contact the hands. The replaceable soft bag 2 is connected
to the
9

2022-06-07
press pumping unit 1 in a fastening manner, so that it can be easily and
conveniently
assembled and replaced, and the eco-friendliness and operating efficiency of
the
replaceable soft bag can be increased.
The foregoing description of the exemplary embodiments of the disclosure
has been presented only for the purposes of illustration and description and
is not
intended to be exhaustive or to limit the disclosure to the precise fomis
disclosed.
Alternative embodiments will become apparent to those skilled in the art to
which
the present disclosure pertains without departing from its spirit and scope.
