Description
- The present invention concerns a sterile packing and a sterilization method using this packing.
- Some activities involve transporting sterile parts or components in sterile packing. This is the case in particular for the component parts of syringes, which must be transported between the production site and an assembly site, to form the syringe, and fill the syringe bodies.
- A known sterilization method used for syringe parts consists of placing these parts in packings made of a flexible and airtight material, then exposing these packings thus filled to gamma rays. This method has the drawback, for the syringe manufacturer, of having to pack the non-sterilized parts in non-sterile packings, then to transmit these packings to a service provider specialized in this type of sterilization, which, after sterilization, transmits these packings to the purchaser of the parts, for assembly and/or filling of the syringes. The use of a specialized sub-contractor of this type constitutes a notable constraint for the syringe manufacturer.
- Another known sterilization method in such an application uses water vapor to sterilize the parts and their packing. This sterilization method is preferred to the radiation sterilization method because it is well-received by the pharmaceutical industry using the syringes, or even required by some users, or is also made obligatory by the nature or material of the packed parts or components. There are not, however, packings making it possible to ensure the perfect performance of sterilization during the sterilization method and, after transport, the perfect preservation of the integrity of the packing all the way to the end user.
- The present invention aims to resolve the abovementioned drawbacks.
- Its objective is therefore to provide a packing making it possible to ensure the perfect performance of a sterilization of one or several objects to be sterilized, in particular by water vapor, to ensure the perfect preservation of sterility during transport and storage of the packing, and to immediately detect any loss of integrity of the packing and therefore any loss of the sterility thereof. The aim of the invention is also to provide a sterilization method using this packing, making it possible to sterilize said objects while ensuring the perfect performance of the sterilization thereof.
- The term “object” will be used below generically to generally designate one or several parts or one or several components to be packed; this term must be understood in the broadest sense, covering all types of parts, products or components, and in particular the component parts of syringes.
- To achieve the aforementioned objective, the packing according to the invention comprises:
-
- a first part, made of flexible and airtight material, defining a first portion and a second portion contiguous to the first portion, said first portion being separated from the second portion by an area suitable to be folded;
- at least one second part, made of a material porous to the sterilizing fluid, forming a pocket for the reception of the at least one object to be sterilized, said second part being connected to said first portion of said first part and being dimensioned so that its edges are, when said second part is connected to said first portion, set back of the edges of said first portion so as to define side assembly areas on said first portion; and
- airtight connection means for the connection of said second portion to said first portion in said side assembly areas.
- The sterilization and packing method according to the invention comprises the steps of:
-
- placing one or several objects to be sterilized in the pocket formed by said at least one second part;
- sterilizing the unit by means of the sterilization fluid;
- folding up said second portion on said first portion, and
- carrying out the assembly of this second portion onto this first portion in the side assembly areas with said connection means.
- The invention thus consists of using a packing comprising a pocket in a porous material, permeable to the sterilization fluid, to contain one or several objects to be sterilized, which is connected to said first portion of a part made of an airtight material; after sterilization, said second portion is folded up onto said pocket so as to cover all of this pocket and is then sealably connected to said side assembly areas of said first portion, thereby isolating the pocket relative to the outside.
- The porosity of the pocket allows a sufficient diffusion of sterilization fluid inside this pocket and around all of the objects contained in this pocket; the airtight connection of said second portion to said first portion makes it possible to perfectly protect these objects with regard to the outside environment and to preserve the integrity of the sterilization done.
- The packing and the method according to the invention therefore have the determining advantages of allowing effective sterilization of objects by the sterilization fluid, perfectly preserving the integrity of the packed objects, and making it possible to immediately show any loss of integrity, and therefore of sterility, of the packing.
- The material of said second portion comprises pores whereof the size can go from 2 to 15 microns and a Log Reduction Value (as defined in the ASTM F-1608 standard) greater than or equal to 3. This can be a film marketed by the company Du Pont De Nemours under the TYVEK® brand, references 1073B, 2FS or 1059B, or the complex marketed by the company WIPAK under the brand WIPAK®, with references Paper 80B or Paper 120B.
- The packing can comprise a third part, made of a flexible and airtight material, dimensioned to be able to contain said first part when folded on said second part, this third part being closed on said first part when folded on said second part and being airtightly sealed with a vacuum created between said third part and said first part.
- This third part strengthens the resistance of the packing to the stresses this packing may undergo during its transport and handling, and the air vacuum created between it and said first part constitutes, at the time of opening of the packing, a demonstration of the preservation of the integrity of this packing, and therefore the preservation of the perfect sterility thereof.
- As a result, in this case the method comprises the steps consisting of:
-
- using said third part;
- folding said third part on said first part when this first part is folded on said second part;
- creating a vacuum between said third part and said first part, and
- tightly sealing said third part while maintaining the vacuum between said third part and said first part.
- The assembly formed by said first part when it is folded on said second part can be independent of said third part; this assembly can also be connected to this third part, in particular by connecting said side assembly areas to said third part.
- Said second part(s) can form said pocket by themselves, for example being folded and being connected to each other on their side edges; said second part(s) can also be flat and be connected to said first part at their perimeter, so as to form said pocket and the opening of this pocket.
- Preferably, said first part is made of a thermoweldable material and said sealing connection means include this material itself, the assembly of said first portion and said second portion of this first part being carried out by thermowelding.
- Also preferably, said at least one second part is made of thermoweldable material and its connection to said first part is done by thermowelding.
- The packing according to the invention can thus be produced particularly simply.
- Said first part and said second part could have any shape of a nature to pack the concerned objects according to the invention. According to one simple embodiment of the packing according to the invention, said first part has a rectangular shape and said first and second portions of this part are defined by the two portions of said first part extending on both sides of a transverse median axis, this transverse median axis corresponding to said area suitable to be folded.
- Preferably, said first part is made of several superimposed layers of flexible and airtight material.
- This plurality of layers minimizes the risk of a loss of integrity of the packing if a hole appears in one layer. Moreover, the risk of having aligned holes decreases as the number of layers increases.
- The invention will be well understood, and other characteristics and advantages thereof will appear, in reference to the appended diagrammatic drawing, illustrating, as non-limiting examples, two possible embodiments of the sterile packing it concerns.
-
FIG. 1 is a flat view of two material parts making up this packing, according to a first embodiment, before filling of the packing; -
FIG. 2 is a side view of these parts; -
FIG. 3 is a view of these parts similar toFIG. 2 , after filling by the objects to be sterilized; -
FIG. 4 is a view of these parts similar toFIG. 3 , after sealing of one of these parts; -
FIG. 5 is a top view of these parts, after said sealing; -
FIG. 6 is a side view of the assembly shown inFIGS. 4 and 5 , after placement in an envelope formed by a third part; -
FIG. 7 is a view of the packing similar toFIG. 6 , after sealing of said envelope, and -
FIGS. 8 to 10 are views similar toFIGS. 2 , 4 and 7 of the packing, respectively, according to a second embodiment. - For simplification, the parts or elements of one embodiment which are found identically or similarly in the other embodiment will be identified using the same numerical references and will not be described again.
-
FIG. 7 illustrates a packing 1 designed to containobjects 2, in particular component elements of syringes, and in particular syringe plungers. Theseobjects 2 together fill a pocket comprised by the packing 1 but, out of a concern for clarity in the drawing, they have only been partially shown: the overall contour formed by theseobjects 2 is defined by a dashed line. - In reference to
FIGS. 1 to 7 , it appears that the packing 1 comprises threematerial parts - The
part 5 is made of a flexible and airtight material, in particular a thermoweldable synthetic material. It is rectangular and defines afirst portion 5 a and asecond portion 5 b contiguous to thefirst portion 5 a, saidfirst portion 5 a being separated from thesecond portion 5 b by amedian area 5 c able to be folded. - The
part 6 is made of a material porous to a sterilization fluid such as water vapor and non-porous to microbic contamination. This material comprises pores whereof the size can go from 2 to 15 microns and a Log Reduction Value (as defined in the ASTM F-1608 standard) greater than or equal to 3. This can be a film marketed by the company Du Pont De Nemours under the TYVEK® brand, references 1073B, 2FS or 1059B, or a complex marketed by the company WIPAK under the WIPAK® brand, reference Paper 80B or Paper 120B. - This
part 6 is rectangular in shape and has dimensions smaller than those of saidfirst portion 5 a; it is connected on three of its sides to thisfirst portion 5 a, while being positioned set back from the edges thereof other than the one connected to saidmedian area 5 c, so as to define threeside assembly areas 5 d on saidfirst portion 5 a. Through this connection on three of its sides to saidfirst portion 5 a, thepart 6 forms apocket 10 for receivingobjects 2 to be sterilized. The connection of thepart 6 to thepart 5 can be done using any suitable means, in particular gluing or thermowelding. - After filling the
pocket 10 with the objects 2 (cf.FIG. 3 ) and placing the assembly, in this state, in a sterilization chamber, theportion 5 b of thepart 5 is folded on thepocket 10 and on theportion 5 a, then is heat-sealed to theside assembly areas 5 d. The heat-sealedareas 11 extend continuously from one end of thefolding area 5 c to the other end, including thepocket 10, such that thispocket 10 and theobjects 2 it contains are perfectly tightly isolated from the ambient air. - The assembly thus formed is then placed in an envelope formed by said material part 7 (cf.
FIG. 6 ), thispart 7 being made of a flexible and airtight material, in particular a thermoweldable synthetic material. - The envelope formed by this
part 7 is then closed on all of said assembly (cf.FIG. 7 ), then is airtightly heat-sealed with a vacuum created between thepart 7 and thepart 5. - As appears from the preceding, the porosity of the
part 6 allows a great diffusion of the sterilization fluid inside thepocket 10 and around all of theobjects 2 contained therein, sufficient to ensure the sterilization of theseobjects 2; the airtight connection of saidsecond portion 5 b to saidfirst portion 5 a enables perfect protection of theseobjects 2 with regard to the outside environment and preservation of the integrity of the sterilization done. - The
part 7 strengthens the resistance of the packing 1 to the stresses this packing may undergo during its transport and handling, and the vacuum created between it and thepart 5 constitutes, when the packing 1 is opened, a demonstration of the preservation of the integrity of this packing, and therefore the preservation of the perfect sterility thereof. -
FIGS. 8 to 10 illustrate a packing 1 identical to that which was just described, except that thepart 5 comprises aring 20 for connecting the packing 1 to a sterile chamber wherein theobjects 2 are designed to be transferred. Thisring 20 comprises a circular base defining an opening for pouring of theobjects 2 and a removable door, which, at this stage of the use of the packing 1, closes this pouring opening. Thering 20 is, for example, of the type described in documents U.S. Pat. No. 6,571,540 and U.S. Pat. No. 6,817,143, and therefore will not be described in further detail. - As appears in
FIGS. 8 to 10 , thering 20 is covered by amembrane 21, which is porous to the sterilization fluid, thismembrane 21 allowing sterilization of thering 20 at the same time the sterilization of theobjects 2 is done. This membrane can in particular be made of the same material as thepart 6. - The invention thus provides a sterile packing and a sterilization method using this packing, having the determining advantages of allowing effective sterilization of objects by the sterilization fluid, perfectly preserving the integrity of the packed objects, and making it possible to immediately detect any loss of integrity, and therefore sterility, of the packing.
- It must be specified that the embodiment of the invention described above was provided purely as an example. It goes without saying that the invention is not limited to this embodiment, but that it extends to all embodiments covered by the appended claims. Thus, the packing 1 can comprise
several parts 6; said part(s) 6 can form said pocket by themselves, being folded and being connected to each other on the side edges then being connected to thepart 5; apart 6 can be connected to theportion 5 a of thepart 5 on its four sides and comprise a slot, in particular median, forming the opening of thepocket 10; thepart 5 can be made of several superimposed layers.
