Metal container
Abstract
A metal container includes a metal body, a cap and a combining
base. The metal body has an upper opening and a thread formed in an
inn upper wall. The cap has a center hole and a circumferential
wall extending down a little and formed with a thread engaging with
the thread of the metal body. The combining base is combined
between the metal body and the cap, having a circumferential
surface provided with two annular grooves and a neck standing up on
its center and extending up and through the center hole of the cap.
The cap, the combining base and the metal body are combined with
each other by means of the threads and the annular grooves, and a
annular gasket is fitted around the annular groove of the combining
base to keep them closely tight.

Claims
1. A metal container comprised: a metal body provided with an upper
opening, and a male thread formed in the outer wall of the upper
opening; a cap closing on said opening of said metal body and
having a round hole in the center, a circumferential wall extending
down and formed with male threads and an annular groove; a
combining base having two annular grooves in a circumferential
surface and a neck standing up on its center and provided with an
opening and threads; and, said combining base combined between said
cap and said metal body by means of said male threads and said
annular grooves and a gasket fitting in one of said annular groove
of said combining base and also fitting tightly in an inner wall of
said metal body.
2. The metal container as claimed in claim 1, wherein said
combining base is made of plastic and easy to make.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to a metal container, particularly to
one provided with a cap and a combining base to threadably engaging
with a container body, for lowering its cost and improving its
practicability.
[0003] 2. Description of the Prior Art
[0004] A conventional metal container 1 shown in FIGS. 1 and 2
includes a metal body 10 and a combining cap 11 made integral with
the metal body 10 as shown in FIG. 2. However, this conventional
metal container 1 has the following disadvantages.
[0005] 1. As the metal body 10 and the combining cap 11 have a
combining portion shaped curved, their processing is rather
difficult, and the welded surface needs grinding, so the whole
surface may have welding marks to harm its outer appearance.
[0006] 2. The combining cap 11 has a projecting threaded tubular
member necessary to be processed several times, enhancing the cost
not a little.
[0007] 3. It making process is rather complicated, causing bad
effect in manufacture.
SUMAMRY OF THE INVENTION
[0008] The invention has been devised to offer a metal container,
which can be assembled closely tight and manufactured with a lower
cost than the conventional ones.
BRIEF DESCRIPTION OF DRAWIWNGS
[0009] This invention will be better understood by referring to the
accompanying drawings, wherein:
[0010] FIG. 1 is an exploded perspective view of a conventional
metal container:
[0011] FIG. 2 is a perspective view of the conventional metal
container;
[0012] FIG. 3 is an explode perspective view of a metal container
in the present invention;
[0013] FIG. 4 is a perspective view of the metal container in the
present invention;
[0014] FIG. 5 is a cross-sectional view of the metal container in
the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0015] A preferred embodiment of a metal container in the present
invention, as shown in FIGS. 3, 4 and 5, includes a metal body 2, a
cap 3 and a combining base 4 as main components combined
together.
[0016] The metal body 2 is provided with an upper opening 20, and a
male thread 21 formed in an inner upper wall.
[0017] The cap 3 is closed on the upper opening 21 of the metal
body 2, having a round hole 30 in the center, a circumferential
wall 31 extending down and provided with male threads 32 and an
annular groove 33.
[0018] The combining base 4 is made of plastic, combined between
the cap 3 and the metal body 2, having an inverted T shape and a
neck formed upright on the center and provided with an opening 40,
and male threads 41 and two annular grooves 42, 43 formed around
the circumferential surface. The annular groove 42 engages with the
threads 32 of the cap 3, and the annular groove 43 fits with an
annular gasket 44.
[0019] In using, the round hole 30 of the cap 3 is fitted around
the neck with the opening 40 of the combining base 4, with the
annular threads 32 engaging with the annular groove 42 of the
combining base 4, and with the gasket 44 fitted around the annular
groove 43. Next, the cap 3 combined with the combining base 4 is
together fitted on the opening 20 of the metal body 2, with the
annular groove 33 of the cap 3 engaging with the male thread 21 of
the metal body. Finally, the gasket 44 fits closely in the annular
groove 43 of the combining base 4, and also fits tightly around the
inner wall of the metal body 2, finishing closing up the metal body
2.
[0020] The metal container according to the invention has the
following advantages, as can be seen from the foresaid
description.
[0021] 1. It is convenient to assemble and disassemble.
[0022] 2. Its cost can be lowered than the conventional ones, as
the combining base 4 is made of plastic.
[0023] 3. The metal body 2, the cap 3 and the combining base 4 can
be combined together tightly and smoothly by means of the fitting
mode.
[0024] 4. The combination of the metal body 2, the cap and the
combining base 4 can be watertight as the combining base 4 and the
metal body 2 are tightly combined with the gasket 44.
[0025] While the preferred embodiment of the invention has been
described above, it will be recognized and understood that various
modifications may be made and the appended claimed are intended to
cover the modifications that may fall within the spirit and scope
of the invention.
