    BACKGROUND OF THE INVENTION
    Bags are known for packaging and applying animal sperm. The bags comprise two walls of plastic material forming the bag having an inside and an outside, an elongated cylindrical tulle with an inner end and an outer end for discharging animal semen from the bag during artificial insemination. The walls are welded together to form a first pocket for the absorption of animal semen and a second pocket that is significantly smaller than the first pocket. The inner end of the tulle is in fluid communication with the first pocket and the outer end of the tulle is in fluid communication with the second pocket. The tulle is fitted at
    DK 2018 70521 A1 insertion of the tulle into a pre-formed bag, the tulle being forcefully inserted into a duct connecting the first and second pockets.
    This involves a number of disadvantages, which are described below.
    The location of the tulle may vary during manufacture. Thus, there may be a greater number of bags which will be removed due to inaccuracy of the position of the tulle during production.
    Introducing the tulle can weaken the material of the bag around the tulle. This can lead to a greater number of bags being discarded during production or worse, the material failing to use the bag.
    The tulle is not securely connected to the bag. Thus, it cannot be excluded that during use, animal sperm will flow out of the bag between the tulle and the bag. Especially when applying pressure to the bag.
    The object of the invention
    It is the object of the invention to provide a bag which addresses these disadvantages.
    It is a further object of the invention to provide a method of making a bag which alleviates these disadvantages.
    It is a further object of the invention to provide a web of bag items for the production of bags which alleviate these disadvantages.
    It is a further object of the invention to provide a method of producing a web of bagpieces that alleviate these drawbacks.
    Description of the Invention
    This is achieved in accordance with the present invention with a bag of the type specified initially, which is characterized in that the tulle is welded together with the inside of the walls along the perimeter of the tulle.
    DK 2018 70521 A1
    Thus, a firm connection is formed between the tulle and the walls of the bag. This ensures that no leakage can occur between the bag wall and the tulle when using the bag. Thus, a more secure bag is obtained.
    The inside of the walls face each other. The outside of the walls face away from each other.
    Furthermore, it is possible to place the tulle in a well-defined position relative to the sidewalls during manufacture. Since this is done beforehand before the welding, the tulle can be placed more precisely than by pushing the tulle forcefully into a duct in a pre-formed bag.
    The inner end of the tulle is understood to mean the end facing the first pocket. By the outer end of the tulle is meant the end facing the other pocket. The outer end is the end where the animal sperm runs out when emptying the bag.
    By tulle is meant a largely cylindrical tube.
    When emptying the bag, an injection tube of cylindrical cross-section can be connected. The cylindrical cross-sectional injection tube may be a catheter.
    The bag has a top, a bottom and sides. These are defined based on the use of the bag. Top and bottom are oriented opposite. The tulle is located at the bottom of the bag. The sides connect the top and bottom. The bag may comprise an opening along the top edge of the bag. Since extending along the top of the bag forms the upper edge of the bag. Opening is used for filling the bag with animal semen. After filling, the bag can be closed by closure welding along the top edge. The closing weld closes the bag opening.
    In artificial insemination, the animal sperm is squeezed out of the bag by applying pressure to the bag. Ideally, the pressure is applied in a continuous manner starting from the top and towards the bottom. The semen runs out of the bag through the tulle and an injection tube connected to the bag by the tulle.
    DK 2018 70521 A1
    According to a further embodiment, the bag according to the invention is characterized in that the inside of the walls is made of a material which can be welded to the tulle.
    The tulle and the inside of the walls may be made of any weldable plastic material. For example, the tulle may be made of high-density polyethylene and the inside of the polyethylene walls.
    According to a further embodiment, the bag according to the invention is characterized in that each wall comprises at least two layers, wherein an inner layer forming the interior of the bag is made of a material which can be welded to the tulle.
    In a multi-layer construction, material properties of different materials can be advantageously utilized. For example, one inner layer may be made of polyethylene and another layer may be made of thermoplastic polyester such as polyethylene terephthalate (PETP). Polyethylene can be welded but has a higher air permeability than PETP. PETP, on the other hand, cannot be welded. The advantage of a construction comprising an inner layer of polyethylene and a second layer of PETP is such that the good welding ability of polyethylene can be combined with the good barrier properties of PETP.
    According to a further embodiment, the bag according to the invention is characterized in that the inner end of the tulle is aligned with the bottom edge of the first pocket or is below the level of the bottom edge and where the tulle and the bottom edge of the tulle form a funnel.
    Thus, the first pocket can be completely emptied during use. If the tulle protrudes into the first pocket or if the bottom edge of the first pocket does not form a funnel, a residual amount of semen may be left in the bag. This will increase the cost as a greater amount of semen is needed. Furthermore, it may decrease the fertility rate of the artificial insemination.
    According to a further embodiment, the bag according to the invention is characterized in that the second pocket comprises a weakening line.
    DK 2018 70521 A1
    In use, the tulle can easily break the sidewall, thereby exposing the tulle so that it can be easily connected to an injection tube. The outer end of the tulle is pressed against the sidewall with the weakening line until the sidewall breaks at the weakening line. Thus, the injection tube having a circular cross section can be connected to the tulle at the outer end of the tulle.
    The line of weakening is preferably provided by the welding of the two side walls. Thus, the line of weakening runs along a side edge of the weld. The line of weakening may be located close to the outer end of the tulle.
    The second chamber may have a constriction in an area near the outer end of the tulle. For example, the second chamber may be essentially of triangular shape. A corner of the triangle may be located at the outer end of the tulle.
    The narrowing means that the side wall can be more easily broken with the tulle. It is easier to apply pressure to a side wall with the outer end of the tulle. Thus, the outer end of the tulle can be easily exposed. Thus, increased usability and time savings are achieved by use.
    The narrowing and weakening line can work together to achieve easy breaking of the wall and exposing the outer end of the tulle.
    According to a further embodiment, the bag according to the invention is characterized in that the outer end of the tulle comprises a cross-sectional narrowing of cone stub shape or approximately cone stub shape.
    The cross-sectional constriction is intended to connect an injection tube with a cylindrical cross-section of different diameters.
    The cross-sectional constriction may be located on the inside or outside of the tulle.
    The cross-sectional narrowing is intended for connection of an injection tube with a cylindrical cross section.
    DK 2018 70521 A1
    Thus, injection pipes with diameters can be connected between the maximum outer diameter of the tulle and the minimum outer diameter of the tulle at its outer end if the cross-sectional narrowing is on the outside of the tulle.
    Thus, injection pipes of diameter between the minimum inner diameter of the tulle and the maximum inner diameter of the tulle at its outer end can be connected if the cross-sectional narrowing is on the inside of the tulle.
    According to a further embodiment, the bag according to the invention is characterized in that the outer end of the tulle comprises an inner and an outer cross-sectional conical or conical stub narrowing.
    By means of the outer cross-sectional narrowing, injection tubes having a cylindrical cross-section having an internal diameter of size or slightly smaller than the outer diameter of the tulle can be connected.
    By means of the inner cross-sectional narrowing, injection tubes having a cylindrical cross-section having an outside diameter of size or slightly smaller than the outer diameter of the tulle can be connected.
    For depth insemination, a catheter may be attached to the outer cross-sectional narrowing and an injection tube on the inner cross-sectional narrowing. Thus, the catheter and injection tubes will be coaxial. The injection tube will be longer than the catheter. A well-defined length difference between the outer catheter and the inner injection tube will allow for a quick and easy depth inspection.
    According to a further embodiment, the bag according to the invention is characterized in that the tulle is symmetrical along its longitudinal direction.
    The tulle is thus the same at both ends. That is, the inner end and the outer end are the same. This is an advantage of assembly. Thus, it is not necessary to orient the tulle with unambiguous orientation of the ends during manufacture of the bag.
    DK 2018 70521 A1
    A further aspect of the invention is a method of making a bag or web of plastic bag blanks for packaging and applying animal semen by artificial insemination, which bag comprises a bottom, a top, sides as well as a width and a height which comprises the following steps:
    overlaying a first foil web and a second foil web forming the walls of the bag,
    - intermittent feeding of the foil webs in a feed direction parallel to the bottom of the bag,
    separating the film webs at the bottom of the bag,
    - positioning a tulle between the foil webs by insertion perpendicular to the conveying direction towards a stop stop,
    - welding the tulle and foil webs into a first set of welding trays along the perimeter of the tulle
    welding the foil webs into a further set of welding trays to form two pockets connected by the tulle,
    advancing the film webs about a length corresponding to the width of the bag,
    - repeating the steps for placing the tulle and welding.
    The method can be used to prepare any of the embodiments of the bag described in the present application.
    The tulle will preferably be welded to the side walls along the entire circumference of the tulle to ensure a tight closure.
    The method may also be used to prepare any of the embodiments of a web of bag items described in the present application. Thus, any mention of the bag in the context of a method for producing a web of bag items will refer to the bag item.
    In one step of the process, the tulle is welded to the foil webs. The purpose is to fix the tulle in relation to the foil webs. Thus, an optimal and well-defined position of the tulle relative to the foil webs is ensured. An area can be welded around the position of the tulle. The area will be small in relation to the entire side area of the bag. Thus, the area welded will typically be less than 20% of the side area of the bag, preferably 10% of the side area of the bag.
    DK 2018 70521 A1
    Optionally, this step can be supplemented with additional welds in the same area with, for example, a second and third set of welding trays.
    In a further step of the method, welding of the film webs is provided to form two pockets connected by the tulle. This step is provided with a further set of welding trays. In this step, the welds in the remaining area of the bag can be welded. Thus, all remaining welds in the bag except the closure weld along the top edge of the bag can be made in this step.
    Closure welding along the top of the bag closes the bag. Thus, the welding is done along the top edge of the bag only after filling the bag.
    The additional set of welding trays may be located in the same tool as the first set of welding trays. Alternatively, the additional set of welding trays may be located in a different tool than the first set of welding trays.
    According to a further aspect of the invention, the process is characterized in that it may further comprise the following steps:
    - repeating welding of the foil webs in a subarea of the bag by a second set of welding trays, located after the first set of welding trays seen in the direction of conveyance.
    The portion area of the bag may be the area around the tulle.
    By another welding around the tulle, the dimensions of the welding trays can be changed so that the pressure the welding tray exerts around the tulle increases. This can be achieved by reducing the diameter of a cylindrical depression in the weld trays.
    According to a further aspect of the invention, the process is characterized in that it may further comprise the following steps:
    - repeating welding of the foil webs in a subarea of the bag by means of a third set of welding trays, placed after the second set of welding trays seen in the forward direction.
    DK 2018 70521 A1
    The advantage of repeating the welding in several subsequent sets of welding trays is that a higher machine stroke can be run. Thus, production can be increased and more bags and / or bag items are produced. In order to provide the welding, a large amount of heat must be deposited in the bag and tulle material. Thus, in a single set of welding trays, welding can take a long time. The welding may take longer than the other steps of the bag manufacturing process. Thus, the weld would be the bottleneck during manufacture. By splitting the weld into several sets of welding trays, the time in each welding tray is reduced. Thus, the preparation of the bag / bag blank can be done at higher machine rates. The weld no longer forms the bottleneck during the manufacture of the bag / bag item.
    According to a further aspect of the invention, the process is characterized in that it may further comprise the following steps:
    the welding or welding is carried out at a temperature between 110 and 240 degrees Celsius, preferably between 140 and 180 degrees Celsius.
    By the temperature of the weld is meant the temperature of the welding trays.
    The temperature may vary according to the feed rate of the bag / bag item. Typically, the temperature will increase as the feed rate increases. Typically, the temperature will be lowered as the feed rate is lowered.
    Furthermore, the temperature may vary at different thicknesses of the walls of the bag. Typically, a higher temperature will be used for thicker walls. Typically, a lower temperature will be used for thinner walls.
    According to a further aspect of the invention, the method is characterized in that the welding temperature may vary between the first, second and third sets of welding trays.
    In the first step of the welding, fixation of tulle and bag or bag item must be ensured. Subsequent steps ensure that the tulle has full welding contact with the walls of the bag.
    DK 2018 70521 A1
    The temperature may be decreasing in the direction of feeding of the bag and or the bag item.
    According to a further aspect of the invention, the process is characterized in that it may further comprise the following steps:
    - providing tulle that is symmetrical along their longitudinal direction.
    The tulle is thus the same at both ends. That is, the inner end and the outer end are the same. This is an advantage of assembly. Thus, it is not necessary to sort the tulle according to the orientation of the ends during the preparation of the bag. Thus, the apparatus for the manufacturing method can be simplified.
    According to a further aspect of the invention, the process is characterized in that it may further comprise the following steps:
    slitting a folded film blank into a first film web and a second film web along a fold edge.
    The slit aims to form two superposed foil webs.
    A further aspect of the invention is a web of bagpieces for packaging and application of animal semen, which web consists of a continuous series of bagpieces comprising bagpipes
    - two walls forming the bag,
    - an oblong cylindrical groove with an inner end and an outer end for discharge of animal semen from the bag during artificial insemination, which walls are welded together to form
    - a first pocket for the admission of animal semen, and a
    a second pocket which is significantly smaller than the first pocket where the inner end of the tulle is in fluid communication with the first pocket and the outer end of the tulle is in liquid communication with the second pocket, which tulle in a closed state of the bag is fully enclosed by the walls. the outer end of the tulle in an open state of the bag is outside the walls, the outer end comprising a cross-sectional cone-shaped constriction or approximately cone-shaped stub,
    DK 2018 70521 A1 where the tulle is welded together with the inside of the walls of the bag along the entire circumference of the tulle, so that a secure closed connection is formed between the tulle and the walls.
    The web of bag items can be provided corresponding to any of the embodiments of the bag described in the present application. Thus, any or all of the peculiarities of the bag of the invention may be present in the web of bag items.
    According to a further embodiment of the invention, the web is characterized in that it comprises, in a side edge forming the top of the bag blank, a carrier strip.
    The carrier strip may extend from the top of the bag to the top of the bag item. The height direction of the bag item extends from the bottom of the bag item to the top of the bag item.
    The carrier strip may extend along the entire side edge of the web.
    As the upper edge of the bag is referred to as the area forming the upper edge of the bag when the bag blank is filled and possibly cut off by the carrier strip.
    According to a further embodiment of the invention, the web is characterized in that the carrier strip comprises a fold in the first and second walls, each forming a channel.
    The channel may be formed by welding the fold.
    The weld may be located on the carrier strip in an area near the top of the bag.
    The first pocket may comprise an opening extending along the upper edge of the bag.
    According to a further embodiment of the invention, the web is characterized in that the first pocket comprises an opening extending along the upper edge of the bag, which upper edge extends parallel to a side edge of the web, and the side edge comprising a fold in the first and second walls. , each forming a channel.

    Detailed description of the invention
    FIG. 1 shows a bag according to the invention. The bag 1 is intended for packaging and application of animal semen, preferably omen semen. The bag includes walls 3 and a tulle 5.
    Perpendicular to the walls 3 formed of plastic material is seen. The walls are welded together. The lines in the figures mark welds. The bag comprises a first pocket 7 and a second pocket 9. The shelf 5 is an oblong cylindrical shelf. The tulle has an inner end 11 and an outer end 13. The inner end 11 is in fluid communication with the first pocket 7, and the outer end 13 is in liquid communication with the second pocket 9. Thus, the tulle 5 brings the first pocket 7 and the second pocket 9 in fluid communication.
    The first pocket is intended to accommodate animal sperm. The second pocket is significantly smaller than the first pocket. The inside 61 of the walls is made of a material weldable to the tulle. The tulle is welded to the inside 61 of the walls along the entire circumference of the tulle.
    DK 2018 70521 A1
    The first pocket 7 is intended as a reservoir for animal semen. The second pocket 9 is significantly smaller than the first pocket 7. The second pocket 9 is not intended to contain animal sperm to a greater extent. Thus, the purpose of the second pocket is to close about the outer end of the tulle 13. Thus, the bag remains closed until a side wall of the second pocket is broken and the outer of the tulle is exposed 13.
    The bag 1 comprises a top 15, a bottom 17 and sides 19. These are defined based on the use of the bag. The top 15 is the side where the animal seat is filled. After filling, the bag can be closed with a closure weld 89 along the top edge 21 of the bag. The bottom is on the opposite side of the top. The tulle is located in the bag in an area at the bottom of the bag 17. Since 19, the top and bottom connect.
    The inner end of the tulle is aligned with the bottom edge of the first pocket 25. The tulle 5 and the bottom edge 25 of the first pocket form the funnel. Thus, the bag can be completely emptied during use.
    The bag comprises a weakening line 27 in the second pocket 9.
    The function of the weakening line is to allow an easy opening of the bag during use. The outer end of the tulle is pressed against the sidewalls with the weakening line 27 while retaining the bottom of the bag. Thus, the bag will open at the line of weakening and the outer end 13 of the tulle 5 will be exposed. An injection tube (not shown) of circular cross section can now be connected to the tulle.
    The line of weakening is done by welding the walls of the bag. Thus, the edge of the weld forms the weakening line.
    Further, the second pocket 9 comprises a constriction 85 about the outer end 13. of the tulle 5. The constriction cooperates with the line of weakening. Due to the narrowing, pressure can easily be exerted on the wall of the bag with the outer end of the tulle. The line of weakening is located near the outer end of the tulle. Thus, the narrowing and weakening line cooperate. Thus, a slight opening of the bag 1 is obtained when the outer end 13 of the tulle 5 is pressed against a wall 3.
    FIG. 2a-d show a tulle 5 according to the invention.
    DK 2018 70521 A1
    FIG. 2a shows the tulle seen perpendicular to the longitudinal direction of the tulle 33. FIG. 2b shows the tulle seen in parallel with the longitudinal direction of the tulle 33. FIG. 2c shows a cross section through the tulle marked A in FIG. 2a. FIG. 2d shows a section marked with B in FIG. 2c of the cross section.
    The end of the tulle comprises an outer cross-sectional narrowing 29. The tulle comprises an inner cross-sectional narrowing 31. The tulle is symmetrical longitudinally. Thus, both ends of the tulle are the same. The cross-sectional constrictions are cone-shaped. The outer corners are rounded. The tulle is made of plastic material. Preferably, the tulle is made of high-density polyethylene.
    The advantage that both ends of the tulle are the same is an easier assembly of the tulle in the manufacture of the bag. When both ends of the tulle are the same, it is not necessary to take into account the orientation of the tulle in the longitudinal direction of the tulle. The magazine holding the tulle in the manufacturing apparatus (not shown) is thus simplified.
    The advantage of having both an inner 31 and an outer 29 cross-sectional constriction is that injection tubes of different diameters can be connected. Thus, injection tubes having an outer diameter slightly larger than the inner diameter of the tulle can be connected by pressing the injection tube into the tulle so that the inner cross-sectional constriction engages the outside of the injection tube.
    Injection tubes having an inner diameter slightly smaller than the outer diameter of the tulle can be connected by pressing the injection tube against the outer cross-sectional narrowing 29.
    FIG. 3-14 schematically show some sub-processes in the preparation of the bag or a web of bag items.
    In FIG. 3 shows an apparatus for making bags and bag items according to the invention. A folded foil blank 87 becomes worn at the bottom. An overlay of a first foil web 35 and a second foil web 37 is formed. The first and second foil webs form the walls of the bag. The foil is advanced in a feed direction 39 which is parallel to
    DK 2018 70521 A1 bag bottom 17. The foil webs are separated at the bottom of the bag. Separation of the foil webs is done by a cylinder rod 41 located between the foil webs at the bottom of the bag.
    FIG. 4-8 show how a tulle 5 is positioned between the film webs 35, 37 by insertion perpendicular to the feed direction. The position of the tulle between the foil webs is made by means of a judgment 43. An embodiment of the judgment is shown in FIG. 5. In FIG. 4 shows the domain of the machine producing the bag. The dome 43 is actuated by a linear reciprocating servo actuator 45. A magazine 47 is seen for tulle 5. A tulle 5 is located in front of the dome. In FIG. 6 and 7 see how the tulle is placed on the dome. The dome 43 is advanced toward the tulle so that a constriction 49 at the tip of the dome is placed at one end of the tulle.
    FIG. 8 and 9 show how the tulle is positioned against a stop stop 51. The stop stop 51 ensures that the tulle has a well-defined position with respect to the foil webs and the first set of welding trays 53.
    FIG. 9 and FIG. 10 further shows a first 53, second 55 and third set of welding trays 57. The welding trays 53, 55 and 57 are in an inactive position.
    Further, a further set of welding trays 58 is seen in an inactive position.
    The first, second and third sets of welding trays weld the tulle and the bag's walls. In the first set of welding trays 53, the tulle 5 is fixed to the walls 3. In the second 55 and the third set of welding trays 57 it is ensured that the welding of tulle and walls is tight and durable.
    The additional set of welding trays welds the remaining portion of the welds 91 to the bag, with the exception of the closure weld 89 along the top edge. Thus, the foil webs are welded together to form two pockets connected by the tulle.
    FIG. 11 shows the welding trays in an active position. In the first set of welding trays 53, the foil webs 35, 37 are welded with the tulle 5.
    DK 2018 70521 A1
    In the second set of welding trays 55 and the third set of welding trays 57, the welding can be repeated with increased pressure on the tulle. This is achieved by reducing the recess 59 to the tulle in the welding trays. Alternatively or simultaneously, the temperature of the weld may be varied between first, second and third weld trays.
    In the further set of welding trays 58, the first 35 and the second 37 foil web are welded together so that the foil webs form the walls of the bag 3. Thus, the remaining portion of the welds 91 is formed for the bag. Exception is the closure weld 89 along the top edge of the bag which is performed only after the bag has been filled.
    FIG. 11 and FIG. 12 shows the welding trays in an active position. FIG. 11 is perpendicular to the direction of advance and in FIG. 12, the welding trays are viewed in perspective.
    FIG. 13 and FIG. 14 shows how the judgment 43 is returned so that a new ridge 5 is placed in front of the judgment. Thus, placement of the tulle can be repeated for the next bag after the foil webs 35, 37 are advanced to a length corresponding to the width of the bag.
    FIG. 15a and b show a sketch of a web 93 of bagpieces 95 with a carrier 69 according to the invention. FIG. 15a shows the path of bagpieces perpendicular to the feed direction 39. FIG. 15b shows the web seen in parallel with the feed direction.
