Embodiment Construction

[0025] The present invention solves the above-mentioned problems. In order to store cryopreservation bags, it is necessary to obtain a shaped bag with built-in volume. The invention consists in producing such a bag in a simple and versatile way.

[0026] In summary, the manufacturing method consists in positioning the insert 40 between a folded film 10 ′, 10 ″ or two flat flat films forming the walls of the bag before standard sealing by high frequency on three sides of the bag between( figure 1 ).

[0027] exist figure 2 The insert 40 is shown inserted between the folded films 10 ′, 10 ″. The insert 40 creates a natural volume in the bag and thus increases the nominal volume at the same time.

[0028] Subsequently, the two substrates 31, 32 are closed around the membrane and the insert 40, as image 3 shown. Due to the fact that the film naturally conforms to the shape of the insert without mechanical strain, there is no stretching of the film during the forming proces...

Abstract

Disclosed is a method of manufacturing a bag (20) for the cryopreservation of thermolabile liquids. The manufacturing method is characterized by being versatile, simple and inexpensive and allows to manufacture single and multi-compartment bags without modifying the main sealing molds (31, 32). The relative size and the number of the compartments (28) can be modified without change in the molds. Only a closure sealing tool (50) must be adjusted as a function of the number of chosen compartments (28). The process is compatible with standard high frequency sealing processes. This method provides bags (20) with uniformly thick walls and with a predetermined bag volume.

Description

technical field [0001] The present invention relates to a method for forming a flexible bag, a system for manufacturing the bag, and the bag itself. More particularly, the present invention relates to bags containing blood material or any biological or cellular material. In particular, the present invention relates to bags that allow cryopreservation while protecting the contents of the bag from any damaging effects of cryopreservation. Background technique [0002] Preservation of blood and cellular biological thermolabile substances involves storage at extremely low temperatures. Thermolabile substances are substances that are easily altered or decomposed by heat. They can be accommodated in bags of plastic material; however, storage at extremely low temperatures creates stresses in the plastic materials and their joints, and accordingly bags used for this purpose must meet stringent requirements. [0003] US Patent 5,928,214 describes a plastic material bag for contain...
