closed space for expelling air therein into a vacuum status so as
to make the litterbag inside be sucked by the intake holes and the
bottom of the litterbag is spread out and fixed on the bottom of
the trash can. Thus the disposition of the litterbag is simplified
and the litterbag is set down more properly.
[0002] There are various designs of trash cans used at homes or
public places such as with or without a cover, an automatically
flip-up lip, or flip top bin by pedal operation. Most of the people
dispose litterbags inside trash cans for the convenience of
cleaning trash can. When they dispose the litterbag, the opening of
the litterbag is arranged on the edge of opening of the trash can,
then the litterbag is pressed down and spread out for making the
litterbag attaching closely on the bottom of the trash can.
However, general litterbags are not so easy to spread out and
attach closely on the bottom of the trash cans. Only part of the
litterbag is spread out thus the garbage is easy to fall outside
the litterbag and the available volume of the litterbag is reduced.
It's not only inconvenience to arrange the litterbag but also
troublesome to clean up garbage outside the litterbag.
SUMMARY OF THE INVENTION
[0003] Therefore, it is a primary object of the present invention
to provide a trash can with function of sucking litterbags. A
plurality of intake hole is arranged surrounding the lower part or
bottom of the trash can. The intake holes are connected to a closed
space with an air pump therein for expelling air into a vacuum
status so as to make the litterbag inside be sucked by the intake
holes. When dispose the litterbag into the trash can, the opening
of the litterbag is arranged on the edge of the opening of the
trash can, Then the bottom of the litterbag is pressed down to the
bottom of the trash can and the air pump is turned on to make the
intake holes adsorb the litterbag. Thus the litterbag is spread out
completely on the bottom of the trash can so that the disposition
of the litterbag is simplified and the litterbag is set down more
properly.
