Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to a cap of a garbage can,
particularly to one able to open the opening of the cap of the
garbage can without need to lift or remove it manually, but
pressing a pressing device with a finger or with a foot pressing
down a pedal.
[0003] 2. Description of the Prior Art
[0004] Garbage cans with caps tally with the requirements of
sanitation and environmental protection; therefore, such garbage
cans have been researched and developed. One of them is a
conventional pedal-controlled garbage can 1 having a cap 10
threadably combined thereon, as shown in FIG. 1, but the cap 10 is
not easy to be assembled with the can body because the interacting
mechanism 12 between the pedal 11 and the cap 10 has lots of
components and is complicated in its structure. In addition, when
the cap 10 is opened or closed by pressing a pedal, there may
produce colliding noises and make the garbage can 1 unstable.
SUMMARY OF THE INVENTION
[0005] The objective of the invention is to offer a cap of a
garbage can, provided with a cap body, a shutter blade device and a
press device, able to open the opening of the cap body of the
garbage can and needless to lift or remove it manually.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0017] A preferred embodiment of an upper cover of a garbage can in
the present invention, as shown in FIGS. 2 to 9, includes a cap
body 2, a shutter device 3, a shutter base 4 and a press device 5
combined together.
[0018] The cap body 2 is ring-shaped, provided with a center
opening 25, having its underside formed with an annular
accommodating chamber 20 fixed therein with a plurality of
positioning posts 21 spaced apart equidistantly on the bottom
surface. The cap body 2 is further provided with plural elastic
engage projections 22 and combining elongate members 23 spaced
apart on the annular bottom surface and a fit protruding members 24
on the circumference.
[0019] The shutter device 3 to be positioned just under the cap
body 2 is composed of multiple arc-shaped shutter members 30 and a
rotary ring 31. Each arc-shaped shutter member 30 has one end
provided with a positioning hole 300 and an engage lug 301. The
rotary ring 31 to be engaged with the engaged lugs 301 of the
arc-shaped shutter members 30 is bored with a plurality of engage
notches 310 and has an insert member 311 provided to extend down
from a certain location and secured thereon with two slidable
position posts 3110, 3111.
[0020] The shutter base 4 to be assembled under the shutter device
3 has its circumferential inner side bored with an annular
accommodating groove 40 having its circumferential wall provided
with plural engage slots 41 and engage projections 42 spaced apart.
The shutter base 4 further has one outer side formed with a
protruding-out combining base 43 with two fit grooves 430 on two
upper ends.
[0021] The press device 5 to be fitted with the combining base 43
is composed of a main body 50, a press plate 51, a swing-and-press
member 52 and two control blocks 53, 54. The main body 50 of the
press device 5 has its opposite sides respectively provided with an
insert block 500. The swing-and-press member 52 is an arc-shaped
plate and has the opposite sides of its underside respectively
bored with a recessed groove 520, 521. The two control blocks 53,
54 are respectively positioned under the two recessed grooves 520,
521 of the swing-and-press member 52. The two control blocks 53, 54
are respectively bored with an oblique slide groove 530, 540. The
press plate 51 to be covered on the main body 50 is bored with a
round hole 510.
[0022] In assembling, firstly, the engage lugs 301 of the
arc-shaped shutter members 30 are respectively inserted in the
engage notches 310 of the rotary ring 31 and then the upper cap
body 2 is covered on the shutter device 3, letting the positioning
holes 300 of the shutter blade device 3 respectively aligned to the
positioning posts 21 of the cap body 2 and the combining elongate
members 23 of the cap body 2 positioned on the upper edge of the
rotary ring 31. Then, bolts are respectively inserted in the
positioning holes 300 of the shutter members 30 and screwed with
the positioning posts 21 of the cap body 2. Next, the pressing
device 5 is inserted in the combining base 43 of the shutter base
4, with the oblique slide grooves 530, 540 of the two control
blocks 53, 54 respectively fitted with the two slidable position
posts 3110, 3111 of the rotary ring 31. Then the insert member 311
of the rotary ring 31 and the two control blocks 53, 54 are
together inserted in the combining base 43 of the shutter base 4,
letting the two control blocks 53, 54 fixed in position.
Subsequently, the swing-and-press member 52 is positioned on the
main body 50 by bolts, and the main body 50 is pressed and fitted
on the combining base 43 of the shutter base 4, letting the
recessed grooves 520 of the swing-and-press member 52 pressed and
fitted with the control block 54 and the elastic engage projections
22 of the cap body 2 respectively engaged with the engage slots 41
of the shutter base 4. Lastly, the press plate 51 of the press
device 5 is covered on the main body 50 to finish assemblage of the
garbage can.
[0023] In using, the cap body 2 is positioned closed on the garbage
can (A) and the interacting rod (A10) of the pedal (A1) of the
garbage can (A) is fitted through the round hole 510 of the press
plate 51. To open the opening 25 of the cap body 2 of the garbage
can (A), only press down the press plate 51 manually to let the
press plate 51 press the swing-and-press member 52, which then
press down the control block 53. Then the slidable position post
3111 is moved obliquely downward guided by the oblique slide groove
530 of the control block 53 so that the rotary ring 31 to rotate
clockwise, and the engage lugs 301 of the shutter members 30 move
rightward together with the engage notchs 310 of the rotary ring 31
as shown in FIG. 5. Thus, with the positioning posts 21 serving as
fulcrums, the shutter members 30 may be moved to retreat to one
side to let the opening 25 of the cap body 2 can be easily
opened.
[0024] To close the opening of the cap body 2, simply continuously
press down the press plate 51, then the swing-and-press member 52
is moved downward and turned to press the control block 54. When
the swing-and-press member 52 is continuously pressed to move the
control block 54 downward, the slidable positioning posts 3111 of
the rotary ring 31 is moved along the oblique slide groove 540 of
the control block 54 so that the rotary ring 31 may rotate
counterclockwise, with the shutter members 30 together with the
engage lugs 301 will be moved leftwards to expand out to close up
the opening 25 of the cap body 2.
[0025] As can be understood from the above description, this
invention has the following advantages.
[0026] 1. It is easy to open or close the opening 25 of the cap
body 2, needless to lift or remove the cap body 2 manually.
[0027] 2. The opening 25 of the cap body 2 is opened and closed by
retreating to one side or expanding out the shutter device 3,
avoiding colliding noises caused by the cap body 2 and the garbage
can (A).
[0028] 3. The cap body 2 has its opening 25 opened by the shutter
device 3, preventing unpleasant odor from spreading about caused by
lifting or removing the cap body manually.
[0029] 4. The rotary ring 31 of the shutter device 3 can be turned
leftward or rightward to actuate the arc-shaped shutter members 30
to retreat to one side or expand out by means of the oblique slide
grooves 530, 540 of the control blocks 53, 54 of the press device
5, convenient and innovative in operating.
[0030] While the preferred embodiment of the invention has been
described above, it will be recognized and understood that various
modifications may be made therein and the appended claims are
intended to cover all such modifications that may fall within the
spirit and scope of the invention.
