Description

"Sachet for packaging liquid substances for artificial animal insemination"

The present invention relates to a liquid conditioning sachet for artificial animal insemination, in particular for porcine and equine species This type of sachet also known as sachet-dose, is well known in the art and has been the subject in particular of FR-B -2 667 504 and FR-A-2 750 399 The sachet for packaging liquid substances for artificial animal insemination according to FR-B-2 667 504 consists of two sheets of thermoplastic material welded by a weld bead delimiting a pocket , according to a 'firm race of general shape defining two small ribs and two large sides when the bag is empty and αont one of which small ribs has an interruption, the weld bead determining, starting from said interruption, a filling duct

The sachets described in this reference allow a rapid volumetπque filling away from air and contamination as well as the coupling of the sachet and the tube or the probe before insemination with a maintenance and a seal assured reliably and a natural emptying of the complete sachet protected from air and contamination provided that their opening is practiced correctly. However, difficulties linked to the opening of the sachets are frequently encountered which pose problems during their use.

For use with this type of bag which has a filling conduit usually extended by an introduction and centering cone, allowing the contents to be recovered or emptied, an opening is made in the bag at the location of said conduit and the end is inserted. free of a probe or a tube in an opening made

Such sachets are very satisfactory and are still used However, difficulties linked to the opening of the sachets which cause problems during their use and often require the use of a tool or an object are however frequently encountered

To overcome these problems, the Applicant has developed a sachet called "peelable sachet" described in FR 2 750 399 which can be opened in a simple and reliable manner without having to use any tool or object. This type of sachet is particularly well suited to contain animal semen and is meeting with growing success

The above sachets, peelable as well as non-peelable, are usually closed by a heat seal process. However, the user of the sachets, in this case the breeder, may not always have an apparatus making it possible to perform the heat seal said bags

It may therefore prove useful to have a sachet for packaging liquid substances for artificial insemination which, after filling, can be closed again other than by heat welding. Breeders with a small farm do not always have a packaging machine to fill the seed bags

It may therefore also prove useful to have a packaging bag for liquid substances for artificial insemination which can be filled without resorting to the use of a packaging machine, even manual. An object of the invention is a sachet for packaging liquid substances for artificial insemination which can be closed other than by heat sealing

More generally, an object of the present invention is a sachet for packaging liquid substances for artificial insemination, the closure of which after filling can be carried out manually without having to use any apparatus for this purpose.

Another object of the present invention is to provide a packaging bag for liquid substances for artificial insemination which can be filled without having to use a packaging machine, even manual. Other objects and advantages of the invention will become apparent from the reading the description below

The present invention meets the above objects and provides a sachet for packaging liquid substances for artificial animal insemination, consisting of two sheets of welded thermoplastic material delimiting a pocket, following a firm trace of generally elongated shape, with two opposite ends. , said bag having at one of said ends an interruption determining a duct and defining a duct area characterized in that one of said sheets of thermoplastic material comprises an adhesive part covered with a detachable coating

In a first embodiment, the liquid conditioning bag for artificial animal insemination of the present invention is characterized in that it comprises an orifice in one of the two sheets of thermoplastic material positioned substantially opposite the duct area and defining an orifice area and in that the bag is sealed in said duct area.

Advantageously, the orifice is placed substantially in the vicinity of the longitudinal axis of the bag. Advantageously, in this first embodiment, one of the two sheets of thermoplastic material comprises in the duct area a peelable weld, defining a peelable weld area. For example, one of the two sheets of thermoplastic material comprises in the duct area a sealing and peiability material such as a wax. Preferably, in this first embodiment, the sachet is sealed in the peelable weld area

The orifice has for example a shape chosen from circular shapes, slots, and cross-shaped perforations.

In a first arrangement of this first embodiment, the bag comprises an integrated closure part and the adhesive part is in the orifice area.

The integrated closing part is intended to cover the orifice once the detachable covering has been removed.

In a first variant of the first arrangement of the first embodiment, the sachet comprises a tab precut in one of the two thermoplastic sheets and the adhesive part surrounds the orifice at its periphery

In a second variant of the first arrangement of the first embodiment, the bag comprises a flap portion substantially in the form of a strip, integrated in one of the two sheets of thermoplastic material, consisting of an adhesive zone covered with a detachable coating, and the adhesive part covered with a detachable coating is in the form of a strip in the orifice area

According to a second arrangement of the first embodiment, the adhesive part covered with a detachable coating is attached and constitutes an attached closure part. The attached closure part is intended to cover the orifice once the detachable coating has been removed.

The insert may be in the form of a label consisting of a support carrying an adhesive sheet covered with a detachable coating.

The adhesive zone of the present invention can be produced by depositing a layer of adhesive substance, for example an adhesive based on acrylic resins or on pressure-sensitive synthetic rubber. According to the invention, the adhesive area can also consist of an adhesive tape

The adhesive area is always covered with a detachable coating, known in the art under the term "liner". The detachable coating can for example be a detachable paper

The adhesive tape according to the invention is an assembly system consisting of a thin carrier, for example paper, a nonwoven, a polymer film, for example a polyester film, etc., coated on both sides with a uniform layer of adhesive. The adhesive layer may be based on acrylic resins or synthetic rubber, pressure sensitive

The thickness of the layer of adhesive substance or uniform layer of adhesive on the adhesive tape is small, for example of the order of 8 to 15 μm

The adhesive properties (adhesion, tack, cohesion) of the adhesive substance or of the uniform layer of adhesive on the adhesive tape can be described as medium. The term "tack" is commonly used in the art to define the adhesion value

According to a preferred arrangement of the present invention, the tack is slightly different on the two opposite faces of the tape or else, in the case of a layer of adhesive substance, on the two opposite sides of said layer. According to an advantageous arrangement of the present invention, the two sheets of thermoplastic material have an offset, for example of approximately 1 to 3 mm, with respect to one another in said withdrawal part.

Furthermore, in the sachets used so far, the identification of the doses contained therein posed problems. In the case, for example, of the semen doses, the identification was carried out either by means of a colored label stuck to the sachet containing said seed, either by adding a colorant to the seed. Such identification methods had drawbacks, in particular, the risk of the label peeling off or the addition of a dye which could adversely affect the quality of the semen, etc. The present invention provides a sachet which overcomes these identification drawbacks , characterized in that it comprises on a part of the thermoplastic sheets a coloring said coloring defines on the sachet a coloring part The coloring part may include an identification

In the case where the dose sachet contains semen (semen) of pig, a color will be assigned to each breed of pig or genetic type and this will be that of the coloring part In such a case, the coloring of the coloring part identifies the breed of pig or the genetic type concerned It is also possible to provide on a part of the thermoplastic sheets a marking zone, which may or may not be separate from the coloring part. The marking zone may include an identification by marking, for example a drawing

Advantageously, the identification by marking according to the invention is carried out so as to appear by transparency

In the case where the sachet-dose contains semen (semen) of pig, the marking zone can thus include the identification by marking of the breed of pig and / or the genetic type concerned

According to a particularly advantageous embodiment of the invention, the liquid which can be used for artificial inseminations is animal semen, a medium or a diluent

The present invention also relates to a use of the sachet to contain a biological liquid substance usable for artificial inseminations.

The substance which can be used for artificial inseminations is for example chosen from animal semen, media and diluents

The present invention is particularly usable in the case where the animal semen is pig semen. In the latter case, it also relates to a use of the sachet in which the coloring and / or marking identify the breed of the pig.

In the first embodiment of the invention, the bag is filled manually by means, for example, of a filling nozzle which is introduced into the orifice

Once the bag has been filled, the filling nozzle is removed, the detachable coating is removed from the adhesive part and the orifice, surrounded by the adhesive part, is capped with the closure part which seals the orifice tightly. use of the sachet, a probe is introduced into the conduit, undoing the solder, which is advantageously a peelable solder, and the sachet is turned over to inseminate the animal

In the first arrangement of the first embodiment, the bag comprises an integrated closure part, for example a tongue or a flap forming part of one of the two sheets of thermoplastic material

In the first variant of the first arrangement of the first embodiment, the closure part is a tongue precut in one of the sheets of thermoplastic material. The orifice, around which an adhesive zone is deposited, is then capped with the tongue. second variant of the first arrangement of the first embodiment the closure part is a flap having substantially the shape of a strip For example, an adhesive portion is prepositioned in the zone intended to be the zone of the orifice before perforation of the sheet of thermoplastic material and before sealing of the bag. The perforation is then carried out through the sheet of thermoplastic material and the adhesive portion After filling the bag, the detachable covers are removed and the flap seals the orifice tightly

In the second arrangement of the first embodiment, the adhesive part covered with a detachable coating is an insert which constitutes a closure part. This insert advantageously has the form of a label. After filling the sachet, the detachable coating is removed. and the closure piece seals the orifice tightly

In this second embodiment, the sachet can be easily filled without requiring a packaging machine

In the second embodiment of the invention, the adhesive part is deposited on the internal face of the sheet of thermoplastic material. The bag does not include an orifice and it is filled by the conduit.
