Semen storage container and its stopper

A semen storage container containing the semen of a male pig is sealed with a stopper having a cone-shape vomiting portion whose point is closed at one end when the semen is used for artificial insemination, a predetermined portion of the cone-shape vomiting portion of the stopper is cut inserted into an insertion tube which is then inserted into the womb of female pig, thereby easily and cleanly carrying out artificial insemination. A window for confirming the amount of semen stored is added to the semen storage pack who se exterior is shading-printed to block a harmful ray of light such as direct ray of light, protecting the semen from deterioration.

BACKGROUND OF THE INVENTION 
1. Field of the Invention 
The present invention relates to a semen storage container for storing the 
semen of a male pig, and in particular, to a semen storage container and 
its stopper, which stores the semen of a male pig and allows the stored 
semen to be cleanly put into the womb of female pig without difficulty 
when the stored semen is used for artificial insemination. 
2. Discussion of Related Art 
In the prior art approach; for artificial insemination of a female pig, the 
semen from a male pig is stored in a semen storage container (a bottle, 
tube or vinyl pack is usually used), and this semen is put into the womb 
of female pig. A conventional semen storage container is constructed in 
such a manner, as shown in FIG. 1, that a space for storing the male pig's 
semen is provided inside a semen storage pack 100 thermal press the semen 
is poured into the inner space of semen storage pack 100 through its inlet 
110. In order to store the semen, inlet 110 is thermal-pressed after the 
semen is poured into semen storage pack 100, thus being sealed completely. 
FIG. 2 shows a configuration for putting the semen stored in storage pack 
100 into the womb of female pig using an insertion tube 120. The sealed 
part of inlet 110 of semen storage pack 100 is opened and insertion tube 
120, a tube for one-time use, is press-fitted into inlet 110. Then, the 
end 121 of insertion tube 120 is inserted into the womb to put the semen 
of male pig, stored in semen storage pack 100, into the female pig's womb. 
However, when the sealed inlet 110 of the semen storage pack is opened and 
the insertion tube 120 is put into the womb of female pig if the diameter 
of the insertion tube is different from that of the inlet 110 of the semen 
storage pack, the insertion tube cannot be fitted into the inlet. In other 
words, various kinds of insertion tubes whose diameters are different 
cannot be used for the inlet having a fixed diameter. That is, the semen 
storage pack is not compatible with various types of insertion tubes. 
Furthermore, the conventional semen storage pack produces unsanitary 
problems because the semen may leak from the gap between the inlet and 
insertion tube. Moreover, the semen storage pack is made of transparent 
vinyl, resulting in deterioration of semen due to its exposure to harmful 
rays of light. 
SUMMARY OF THE INVENTION 
An object of the present invention is to provide a semen storage container 
and its stopper, for improving the semen storage pack's compatibility with 
various kinds of insertion tubes having different diameters, sanitation 
and economic effect. 
Another object of the present invention is to provide a semen storage 
container in which a window for confirming the amount of semen stored in a 
semen storage pack Another object of the invention is to provide a semen 
storage container for such as direct ray of light, protecting the semen 
from deterioration due to harmful rays of light. 
In accordance with the present invention, a semen storage container, 
includes a stopper and a connection tube having a predetermined and a 
closed point. The connection tube is press-fitted into the inlet or outlet 
of the semen storage container. A cone-shape vomiting portion is connected 
to one end of the connection tube. 
The present invention, includes an inlet that is connected to a hollow 
placed on its top, a connection tube whose one end is connected to a 
cone-shaped vomiting portion, which is press-fitted into the inlet, the 
point of the cone-shaped vomiting portion being closed, and a prominence 
for fixing the connection tube, the prominence being placed on a 
predetermined portion of the connection tube or cone-shaped vomiting 
portion.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT 
FIG. 3-4 illustrate a stopper 200 which is used with a semen storage 
container according to the present invention. A cylindrical connection 
tube 210 is press-fitted into an inlet 310 (see FIG. 5) of a semen storage 
pack for storing the semen. A cone-shaped vomiting portion 230 is formed 
at one end of connection tube 210, which end is opposite to its other end 
which is fitted into the inlet 310. A prominence 220 is placed on a 
predetermined portion of connection tube 210, to determine the depth of a 
portion of connection tube 210, that is press-fitted into the inlet of the 
semen storage container, and to fix connection tube 210 within the inlet. 
Connection tube 210 and cone-shape vomiting portion 230 whose point is 
closed are internally connected. Thus, when a predetermined portion of 
cone-shaped vomiting portion 230 is cut, the semen stored in the storage 
pack is vomited from cone-shaped vomiting portion 230 through connection 
tube 210. 
With reference to FIG. 5, a space for storing the semen is formed inside 
semen storage pack 300 through a sealing process. The semen of a male pig 
is poured into the space through inlet 310. a sloped hollow portion 320 
which is connected to inlet 310, to stably fix prominence 220 of stopper 
200. Hollow portion 320 is also formed through sealing. After the semen of 
male pig is poured into semen storage pack 300, connection tube 210 of 
stopper 200 is press-fitted into inlet 310 of storage pack 300, to seal 
it. Here, prominence 220 sits on hollow 320 to allow connection tube 210 
to be inserted and fixed within the storage pack at a proper depth. 
When the semen stored is used for artificial insemination, a predetermined 
portion of cone-shaped vomiting portion 230 of the stopper is cut to open 
its point portion. By doing so, the liquid semen is vomited from 
cone-shape vomiting portion 230 through connection tube 210 of the 
stopper. Cone-shape vomiting portion 230 is inserted into an insertion 
tube 400 which is then inserted into the womb of a female pig, thereby 
putting the semen stored in storage pack 300 into the womb. Here, 
cone-shaped vomiting portion 230 of stopper 200 has different diameters in 
the direction of its length. Accordingly, it can be inserted into various 
kinds of insertion tubes with different diameters. That is, in case of a 
narrower insertion tube, cone-shaped vomiting portion 230 is inserted 
there into a little, and in case of wider one, it is inserted there into 
more. A piercing hole through storage pack 300, stopper 200 and insertion 
tube 400 is formed to allow the semen to flow into the female pig's womb. 
A embodiment of the present invention is shown in FIGS. 6, 7a and 7b. An 
inlet 540 for pouring the semen into semen storage pack 500 is formed at 
the bottom of the storage pack, and an outlet 530 for vomiting the semen 
is formed at its top. Stopper 200 with a cone-shaped vomiting portion 230 
whose point is closed is fixed into outlet 530 to allow the semen to be 
externally vomited through outlet 530 and stopper 200. A shading means 580 
protects the semen from deterioration due to harmful rays of light. 
Cylindrical connection tube 210 of stopper 200 is inserted and fixed into 
outlet 530 of semen storage pack 500. One end of connection tube 210 is 
connected to cone-shaped vomiting portion 230. Prominence 220 is placed on 
a predetermined portion of connection tube 210 or cone-shaped vomiting 
portion 230 to easily determine the depth of a portion of connection tube 
210, that is inserted into outlet 530 of storage pack 500, and to fix 
stopper 200 into the storage pack. A semen storing space 520 where the 
semen is stored is formed inside storage pack 500 through thermal press. 
The semen is poured into space 520 through inlet 540 placed at the bottom 
of storage pack 500. 
After a specific amount of semen is poured into semen storing space 520, 
inlet 540 is sealed by thermal press. Connection tube 210 of stopper 200 
is inserted into outlet 530 at the top of storage pack 500. In this state 
outlet 530 is sealed by stopper 200 so that cone-shaped vomiting portion 
230 protrudes from storage pack 500. Prominence 220 of stopper 200 
supports stopper 200 and fixes it into storage pack 500. The depth of a 
portion of connection tube 210, that is inserted into outlet 530 of the 
storage pack is easily determined. 
In order to use the liquid semen stored for artificial insemination, a 
predetermined portion of cone-shaped vomiting portion 230 of stopper 200 
is cut using a scissors or knife to open its point portion. By doing so, 
the semen stored in storage pack 500 is vomited from cone-shaped vomiting 
portion 230 through connection tube 210 of the stopper. Cone-shaped 
vomiting portion 230 is inserted into an insertion tube 400 whose end 410 
is then inserted into the womb of a female pig, thereby putting the semen 
into the womb. Cone-shaped vomiting portion 230 of stopper 200 has 
different diameters in the direction of its length. Accordingly, it can be 
inserted into various kinds of insertion tubes with different diameters. 
That is, in case of a narrower insertion tube, cone-shaped vomiting 
portion 230 is inserted there into a little, and in case of wider one, it 
is inserted more. A piercing hole through storage pack 500, stopper 200 
and insertion tube 400 is formed to allow the semen to flow into the 
female pig's womb. The semen storage container of the present invention 
also includes a shade 580 formed on its exterior, as shown in FIG. 7A, for 
blocking harmful ray of light thus protecting the semen stored in the 
storage pack. Shade 580 may be formed through printing using an ink or 
paint. In general, when the semen is exposed to direct rays of light, for 
example, the survival rate of its spermatozoon is remarkably decreased. 
Accordingly, it is preferable that semen storage pack 500 includes shade 
580 so as not to directly expose the semen to the ray of light during its 
storage or artificial insemination. 
Furthermore, there is a window for confirming the amount of semen, placed 
on a predetermined portion of the front or back of storage pack 500. This 
window 560 is easily formed in such a manner that, when shade 580 is 
printed, the printing is applied to a predetermined portion of the 
exterior of the storage pack other than the portion of window 560. 
Moreover, in order to precisely confirm the amount of semen through window 
560, graduation markings 561 are printed on the window when shade printing 
is performed, to easily confirm the amount of semen charged in the storage 
pack or the amount vomited when used for artificial insemination. 
Semen storage pack 500 further includes a transparent window 570 on a 
predetermined portion, to examine if the spermatozoon is alive through a 
microscope without opening of storage pack 500. As shown in FIG. 7B, 
transparent window 570 is located at the same portions of the front and 
back of storage pack 500, and it is formed during the shade printing. 
Specifically, shade 580 is formed by printing on a predetermined portion 
of the exterior of the storage pack, other than portions which are used 
for the the transparent window 570. By doing so, shade 580 and transparent 
window 570 are simultaneously formed. Through the transparent window 570, 
it is possible to examine whether the semen charged in storage pack 500 is 
alive or not. Moreover, a hanging hole 550 with a predetermined diameter 
is formed in a predetermined portion of thermal pressed portion 510 of the 
storage pack, to hold the storage pack easily. 
According to the present invention, when the semen storage pack containing 
the semen is open for artificial insemination, various kinds of insertion 
tubes with different diameters can be used for the cone-shaped vomiting 
portion of the stopper, producing satisfactory results in terms of 
sanitation and economy. Furthermore, harmful rays of light are blocked to 
increase the spermatozoon's survival rate. Moreover, it is possible to 
easily confirm the amount of semen charged in the storage pack and the 
amount vomited during artificial insemination, and to examine if the 
spermatozoon is alive within the sealed storage pack. 
It will be apparent to those skilled in the art that various modifications 
and variations can be made in the semen storage container and its stopper 
of the present invention without departing from the spirit or scope of the 
invention. Thus, it is intended that the present invention cover the 
modifications and variations of this invention provided they come within 
the scope of the appended claims and their equivalents.
