Sealing structure for a spray gun reservoir
Abstract
A sealing structure for a spray gun reservoir comprises a can
and a lid. The can has an opening at one end with a curved edge
around the opening. A circular trough is formed within an inner
wall close to the opening. The circular trough is formed by
starting one end in a level with the extension line gradually
deviating from the line to cause a different height of the two
ends. The lid comprises a reduced portion with a circular rib
surrounding an outer wall of the reduced portion, corresponding to
the circular trough of the can. A gap is formed around an inner
wall of the lid corresponding to the curved edge of the can so that
the lid covers the can with the circular rib inserting into the
circular trough for security purpose.

Claims
I claim:
1. A sealing structure for a spray gun reservoir comprising a can
and a lid, said can comprising an opening with a circular trough
close to said opening, said circular trough being formed by
starting one end from an inner wall of said can and continuous to
drawn a line across the inner wall till it reaching to the starting
end, said line being drawn in a different height from original,
thus causing two ends in a different height; said lid comprising a
reduced portion with a circular rib formed around an outer wall
thereof corresponding to said circular trough of said can; thus, by
covering said lid on said can, said circular rib being guided into
said circular trough and to secure said can.
2. The sealing structure for a spray gun reservoir, as recited in
claim 1, wherein said opening of said can comprises a curved edge,
and said lid comprises a gap corresponding to said curved edge of
said can.
3. The sealing structure for a spray gun reservoir, as recited in
claim 1, wherein two ends of said circular trough are shaped in
rounded and dented.
4. The sealing structure for a spray gun reservoir, as recited in
claim 1, wherein two ends of said circular rib are shaped in
rounded.
Description
FIELD OF THE INVENTION
[0001] This invention relates to a sealing structure for a spray
gun reservoir, and more particularly to a can having a circular
trough close to an opening of the can, and a lid having a circular
rib on a reduced portion of the lid to secure with the circular
through of the can.
BACKGROUND OF THE INVENTION
[0002] A conventional spray gun reservoir comprises a can 3 and a
lid 4, as shown in FIG. 3. The can 3 has a flat top on an open end
while the lid 4 has a reduced portion 41 to be inserted into the
can 3 to seal the can 3. This sealing structure may easily be
loosened and the paint in the reservoir may be spoiled out.
SUMMARY OF THE INVENTION
[0003] It is the primary object of the present invention to provide
a sealing structure for a spray gun reservoir, which provides a
secure sealing structure to prevent paint from leakage.
[0004] It is another object of the present invention to provide the
sealing structure for a spray gun reservoir, which is save in
use.
[0005] It is a further object of the present invention to provide
the sealing structure for a spray gun reservoir, which is easy to
open and to seal.
BRIEF DESCRIPTION OF THE DRAWINGS
[0006] FIG. 1 is an exploded view of the present invention
[0007] FIG. 2 is an assembly view of the present view, partially
sectioned, and
[0008] FIG. 3 is an assembly view of a prior art, partially
sectioned.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0009] As shown in FIGS. 1 and 2, the present invention is
generally composed of a can 1 and a lid 2.
[0010] The can 1 comprises an opening 11 with a curved edge 13 on
the top edge end. A circular trough 12 is formed by starting from
one end in a level with the extension line gradually deviating from
the line, which causes a different height of the two ends. The two
ends of the circular trough 12 are in rounded and dented shape for
easy connection.
[0011] The lid 2 comprises a reduced portion 21 with a circular rib
22 surrounding the outer wall of the reduced portion 21,
corresponding to the circular trough 11 of the can 1. A gap 23 is
formed around the inner wall of the lid 2 corresponding to the
curved edge 13 of the can 1. Two ends of the circular rib 22 of the
lid 2 are formed in rounded for easy connection.
[0012] By covering the lid 2 on the can 1, the circular rib 22 may
be easily guided into the circular trough 12 and to secure the can
1 properly.
