ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a cap of glue container, and particularly to an injection tube of the container cap, which can be used generally, or mounted with a dispensing tip to dispense glue.
2. Description of the Prior Art
In the conventional glue, Alkyl-2-cyanoacrylat which is usually referred as instant glue or three-second glue, the cyanoacrylat can quickly be polymerized at room temperature without adding catalyst. Such quick polymerization is caused by a weak-base substance to make an anionic polymerization. Since such glue has a strong gluing force, it is subject to causing a preservation and storage problem in a container after each use.
The conventional container for a glue of cyanoacrylat is usually made of a high-density polyethylene; as shown in
FIG. 1
, the threaded cap
41
of the container has an injection tube
42
extended out of the cap; the injection tube
42
includes an elongate cylindrical surface
43
and a tapered cylindrical surface
45
. The elongate cylindrical surface enables the tapered cylindrical surface to extend out at a given length to facilitate dispensing glue. The outer end of the elongate cylindrical surface of the injection tube is furnished with several fastening rings to facilitate a protection cap
46
to mount thereon. The tail end of the injection tube
42
on the front end of the container
40
is sealed before use. When in real use, the center of the injection tube
42
must be stabbed through with a needle to provide a small hole so as to let the glue flow out. As soon as the injection tube
42
is stabbed to have a small hole, the small hole is subject to being closed as a result of the hardening effect of glue; then, the small hole will be unable to stab through with a needle; however, the injection tube
42
can be opened by cutting a portion of the tapered cylindrical surface
45
by means of a knife; in that case, the small hole in the tapered cylindrical surface
45
will be a larger hole; then, the moisture in the air will react with the glue, i.e., the glue in the container will soon become hardened and useless.
The injection tube
42
on the front end of the conventional container for cyanoacrylat glue is usually furnished with an elongate and tapered cylindrical surface; if the glue can be used up within a short time, the elongate and tapered cylindrical surface can directly be used as an injection tube
42
; otherwise, the glue can not be conserved for a longer time aside from the tail end of the injection tube being closed and unable to use next time.
SUMMARY OF THE INVENTION
The prime feature of the present invention is that the outer end of the injection tube on the container cap is furnished with an elongate and tapered cylindrical surface. The inner part thereof is furnished with a cylindrical surface for mounting a dispensing tip; between the two cylindrical surfaces, there is s guide shoulder. The elongate and tapered cylindrical surface on the front end of the injection tube can be stabbed through with a needle. The cylindrical surface on the inner part of the injection tube can be cut off with a knife from the guide shoulder, and then a dispensing tip having different diameter can be mounted on the cylindrical surface.
Another feature of the present invention is that the top center of the elongate and tapered cylindrical surface of the injection tube has a recess spot, which can easily be located and stabbed with a needle point to open the sealed end of the injection tube.
Still another feature of the present invention is that the injection tube of the container cap has two different cylindrical surfaces; when the container is filled with glue, a single container cap may be used to close the container. As soon as a user purchases the glue, the user can select an injection tube with a cylindrical surface to fit the usage desired.
A further feature of the present invention is that, after the sealed end of the tapered cylindrical surface of the injection tube is stabbed through for first use, the sealed end might be closed and unable to stab through next time; in that case, the elongate and tapered cylindrical surface can be cut off, and a dispensing tip may be mounted thereon for further use.
A still further feature of the present invention is that the inner part of the injection tube on the container cap is furnished with a cylindrical surface for mounting the dispensing tip; the cylindrical surface may be cut off with a knife from the guide shoulder; then, the cylindrical surface left can be mounted with a dispensing tip having different diameter.
