Container bag for containing semen for artificial insemination of animals
The present invention relates to a container bag ( 1 ) for containing semen for artificial insemination of animals, of the types which are formed by at least two sheets ( 2.1, 2.2 ) of sealed thermoplastic material, forming a tubular body ( 3 ) with an inner hollow ( 4 ) divided by means of a central constriction ( 5 ) into first and second contiguous enclosures ( 7.1, 7.2 ) communicated by means of a cannula ( 6 ) secured in said constriction ( 5 ), which bag comprises a closure plug ( 10 ) for closing said cannula ( 6 ) secured to the bottom ( 13 ) of the second enclosure ( 7.2 ) of the inner hollow ( 4 ), means for securing the cannula ( 6 ) to the central constriction ( 5 ), and means for securing the closure plug ( 10 ) to the bottom ( 13 ) of the second enclosure ( 7.2 ).
1. Container bag for containing semen for artificial insemination of animals being formed by at least two sealed sheets of thermoplastic material, forming a tubular body with an inner hollow perimetrically closed except at at least one of its ends and divided by means of a central constriction into first and second contiguous enclosures communicated by means of a cannula secured in said constriction, the container bag comprising:
a closure plug for closing said cannula secured to the bottom of the second enclosure of the inner hollow;
means for securing the cannula to the central constriction, and;
means for securing the closure plug to the bottom of the second enclosure,
wherein the closure plug for closing the cannula comprises a flexible longitudinal body that can be tightly fitted in the cannula, and a head outside same, whereby the closure plug is secured to the bottom of the second enclosure
and further including means for opening the bag through section of the second enclosure,
the means for opening the bag comprising a pre-cut line in a section of the second enclosure and a hole limiting said section.
2. Container bag for containing semen for artificial insemination of animals according to claim 1 , wherein the cannula is formed by a tube comprising a flattened head at a first end.
3. Container bag for containing semen for artificial insemination of animals according to claim 2 , wherein the means for securing the cannula to the central constriction are formed by welding the head of the cannula to the bag in said central constriction.
4. Container bag for containing semen for artificial insemination of animals according to claim 1 , further comprising means for separating the two sealed sheets of thermoplastic material at the at least one of its non-perimetrically closed ends.
5. Container bag for containing semen for artificial insemination of animals according to claim 1 , wherein the cannula is of a length such that the second end of the tube forming the cannula protrudes from the pre-cut line of the section of the second enclosure.
6. A series of container bags according to claim 1 , wherein the bags are presented in series, attached to one another by means of pre-cut lines which separate heat-sealing areas of contiguous bags.
