Container for sterilizing flexible bags
A container for sterilizing flexible bags can be for pharmaceutical use. The container includes an upper flat structure including at least one element supporting the flexible bags and designed to accommodate a plug port of the flexible bag. The support element includes at least one fastening element, which is suitable for retaining the flexible bags once they are inserted into the support element. The container also includes a lower receptacle designed to contain the upper flat structure and to couple to the upper flat structure in a detachable manner. The container further includes a cap for hermetically sealing the lower receptacle.
1. A hermetically-sealed container holding a plurality of flexible bags to be sterilized for pharmaceutical use, comprising:
an upper flat structure comprising a plurality of supports for said flexible bags, each of the supports comprising a slot and a notch;
each of the plurality of flexible bags comprising a port-plug, wherein each port-plug is inserted through the slot of one of the supports and accommodated in the notch of said one of the supports such that each flexible bag is retained within the slot and above the notch of one of the supports; and
a lower receptacle containing said upper flat structure and flexible bags, wherein the lower receptacle is coupled to the upper flat structure in a detachable manner and such that the upper flat structure serves as a cap hermetically sealing said lower receptacle.
2. The hermetically-sealed container holding a plurality flexible bags to be sterilized for pharmaceutical use according to claim 1 , containing from 2 to 250 flexible bags.
3. The hermetically-sealed container holding a plurality of flexible bags to be sterilized for pharmaceutical use according to claim 2 , containing from 2 to 180 flexible bags.
4. The hermetically-sealed container holding a plurality of flexible bags to be sterilized for pharmaceutical use according to claim 1 , wherein said container has the shape of a rectangular parallelepipedon.
5. The hermetically-sealed container holding a plurality of flexible bags to be sterilized for pharmaceutical use according to claim 1 , wherein the container is made of high-density polyethylene (HDPE).
6. The hermetically-sealed container holding a plurality of flexible bags to be sterilized for pharmaceutical use according claim 1 , wherein each of the supports is a bar with a T and/or L-shaped cross-section which is attached in a non-detachable manner to the upper flat structure of the container.
7. The hermetically-sealed container holding a plurality of bags to be sterilized for pharmaceutical use claim 1 , wherein said notches are semi-circle-shaped notches made in said supports.
8. The hermetically-sealed container holding a plurality of flexible bags to be sterilized for pharmaceutical use according to claim 7 , wherein said semi-circle has a diameter greater than the port-plug of the flexible bag, but smaller than the diameter of a flange of the port-plug of said bag.
9. A method for filling/sterilizing the hermetically-sealed container for sterilizing flexible bags according to claim 1 , the method comprising:
a) inserting the port-plug structure of a flexible bag through a slot formed by the supports of said flexible bags at an insertion region, which elements are located in the upper flat structure of said container;
b) placing said bag in the notch which is furthest from the insertion region of said bag through the support elements;
c) inserting new flexible bags through the support elements until all the notches of the upper flat structure of said container are full;
d) inserting said upper flat structure into the lower receptacle of the container;
e) sterilizing said container.
10. The method according to claim 9 , wherein the new flexible bags are gradually placed in such a way that a first row of bags in the notches furthest from the insertion region of said bag through the supports is filled.
11. The method according to claim 10 , wherein the first row of bags are alternately formed.
12. The method according to claim 9 , wherein the sterilization in step (e) is carried out by using gamma rays or electron beam (E-beam).
13. The method according to claim 9 , wherein said method is carried out manually.
14. The method according to claim 9 , wherein said method is carried out automatically using a robotic arm.
15. The method according to claim 14 , wherein said robotic arm makes a horizontal movement parallel to the floor in order to insert the port-plug structure of the flexible bag through the slot formed by the supports of said flexible bags (step a) and a vertical movement towards the floor in order to place said bag in the notches (step b) of said container.
