Description

Technical Field

[0001] The present invention relates to the technical field of liquid containers comprising a bag intended to contain a liquid, for example animal semen, in particular porcine semen, and a cap closing the bag. Such containers allow the packaging, storage, preservation and transport of the liquid with a view to its distribution and subsequent use. In the case of a container intended to receive animal semen, the latter is subject to strict constraints in terms of hygiene, confinement and protection of the liquid contained against the external environment. Prior art

[0002] Containers are known, particularly for packaging animal semen, comprising a bag and a cap closing the bag. Such containers are also called "Semen bags" in English. The cap of these containers is breakable. More precisely, they comprise a hollow tubular portion and a sealing portion closing the tubular portion and connected to the main portion by a breakable connection. By breaking the cap at the breakable connection, the sealing portion of the cap is separated from the main portion, allowing the distribution of the liquid contained in the bag.

[0003] A disadvantage of these prior art containers is that after breaking the cap to detach the sealing portion, the latter remains in the hands of the user of the container and is particularly cumbersome. The user must then get rid of the detached sealing portion, even though he does not necessarily have a trash can nearby. This is particularly true when using a container to carry out animal insemination. In this situation, after breaking the cap, the operator is encumbered by the detached sealing portion, which risks disrupting his movements.

[0004] In addition, the filling portion may be misplaced and fall onto the ground, causing pollution of the said ground if it is not subsequently collected. Statement of the invention

[0005] An aim of the present invention is to provide a container for liquid which overcomes the aforementioned drawbacks.

[0006] To do this, the invention relates to a container for a liquid, the container comprising: a pouch comprising at least a first film and a second film assembled together so as to form at least one border for the pouch, said pouch having an interior volume defined between the first and second films, said pouch having a liquid outlet; and a plug cooperating with the pouch so as to close said liquid outlet, said plug having at least one tubular portion in fluid communication with the interior volume of the pouch and a closure portion connected to the tubular portion by a breakable connection, said closure portion of the plug being at least partially arranged in said border of the pouch, between said first and second films of the pouch.

[0007] Without departing from the scope of the invention, the container, and more specifically the pouch, can contain all types of liquids, for example drinks, cosmetic products or even medical products. Preferably, the container is intended for animal insemination, so the pouch is configured to receive animal semen. The container advantageously has the shape of a flexible gourd.

[0008] Preferably, the container according to the invention is a single-use container. Alternatively, and without departing from the scope of the invention, said container may be a reusable container, capable of being filled with liquid several times.

[0009] The bag and the cap together define the interior volume intended to receive and contain the liquid. The bag and the cap form a hermetic unit protecting the liquid from the external environment.

[0010] The container according to the invention allows the packaging, storage, preservation and transport of the liquid for subsequent use.

[0011] The liquid outlet allows liquid to be extracted from the bag for dispensing. The cap is placed at the liquid outlet and prevents liquid from escaping from the bag, as long as the sealing portion is connected to the tubular portion of the cap.

[0012] The first and second films are arranged one above the other and superimposed.

[0013] Each of the first and second films advantageously has at least one first edge, said films being assembled together along their first edges so as to define said border of the pocket.

[0014] Preferably, each of the first and second films has a plurality of edges, the first and second films being joined along all of their edges.

[0015] Preferably, the first and second films are assembled along their periphery, so as to form the pocket.

[0016] Preferably, the first and second films are joined by welding.

[0017] The first and second films are advantageously generally rectangular in shape. According to this non-limiting variant, each of the first and second films comprises four edges.

[0018] Preferably, the first film is substantially identical to the second film.

[0019] Advantageously, the first and second films are flexible. Preferably, the first and second films are formed from a plastic material. Preferably, substantially the entire pouch is formed from a single material, more preferably a plastic material. Preferably, the first and second films are non-deformable or slightly deformable.

[0020] Advantageously, the first and second films each have at least one edge portion arranged opposite a corresponding edge portion of the other film and which is not assembled to this corresponding edge portion, so as to form an outlet opening for the pocket, defining the liquid outlet. Preferably, this outlet opening is formed in the edge of the pocket.

[0021] The plug advantageously extends in a main direction. The plug is advantageously formed from a plastic material.

[0022] The tubular portion of the cap is hollow. The tubular portion extends along the main direction of the cap. It is advantageously circular in cross-section. It is in fluid communication with the interior volume of the bag so that liquid can penetrate it when the bag contains such liquid. The tubular portion forms a conduit for guiding and distributing the liquid precisely.

[0023] Preferably, the tubular portion and the closure portion of the stopper form a single piece. Advantageously, the length of the tubular portion is substantially equal to two-thirds of the length of the stopper considered along the main direction of the stopper. Advantageously, the length of the closure portion is substantially equal to one-third of the length of the stopper considered along the main direction of the stopper.

[0024] When connected to the tubular portion, the sealing portion of the plug seals said tubular portion and prevents liquid from exiting said pocket via the tubular portion.

[0025] Preferably, the tubular portion of the plug has a distal end portion, the closure portion being connected to said distal end portion via said breakable connection. The closure portion advantageously extends in the extension of the tubular portion.

[0026] A breakable connection means a connection that can be manually broken by a user, in order to partially or completely separate the closure portion from the tubular portion of the cap, and thus put the tubular portion in fluid communication with the outside of the container. The breakable connection is configured to be easily broken by the user and with minimal effort. No additional tools are required to break the breakable connection. Preferably, the breakable connection is configured so that, when the latter is broken, the closure portion is completely detached from the tubular portion of the cap.

[0027] Given this breakable connection, the stopper can be described as a breakable stopper.

[0028] Preferably, but not limited to, the breakable connection may be a reduced strength portion of the plug.

[0029] Preferably, the sealing portion is entirely disposed in said border of the pocket, between said first and second films of the pocket.

[0030] According to the invention, the sealing portion of the plug extends at least partly into the edge of the pocket, between said first and second films of the pocket. In other words, the sealing portion is embedded in the edge and taken between the first and second films. The sealing portion is therefore linked to the edge and to the pocket and cannot be detached therefrom, except by tearing off the first and second films.

[0031] To dispense the liquid contained in the container pocket, the operator first breaks the breakable connection. Without limitation, the breakable portion can be broken by pivoting the closure portion around an axis of the tubular portion, or by tilting the closure portion relative to the tubular portion of the cap.

[0032] Once the breakable bond is broken, the sealing portion is detached from the tubular portion of the stopper, and is no longer connected to this tubular portion. The tubular portion of the stopper is then opened and the liquid can be dispensed via said tubular portion, from the distal end portion of this tubular portion.

[0033] Thanks to the invention, since the sealing portion is arranged in the edge of the pocket, the latter remains connected to the pocket despite the breakage of the breakable connection. The sealing portion is maintained between the first and second films. Therefore, the sealing portion is not released and remains integral with the container.

[0034] Therefore, said closure portion does not remain in the user's hands and does not hinder the user's movements. The bulk caused by the closure portion after breaking the cap is greatly reduced. The dispensing of the liquid can be carried out more easily, without having to have the closure portion. Thanks to the invention, it is not necessary for the user to throw the closure portion in the trash or put it in his pocket.

[0035] In addition, the said sealing portion is not likely to be lost or fall onto the ground, thus reducing the pollution caused by the container.

[0036] Without departing from the scope of the invention, only the sealing portion of the plug may extend into the edge of the pocket, between said first and second films of the pocket. Alternatively, a larger portion of the plug may extend into the edge, between the first and second films.

[0037] Preferably, at least one of the first and second films is welded onto said sealing portion of the cap. Preferably, the first and second films are welded onto said sealing portion of the cap.

[0038] According to a particularly advantageous aspect, the tubular portion of the plug has an open distal end portion connected to the closure portion via said breakable connection, at least said distal end portion of the tubular portion being arranged in said border of the pocket, between said first and second films of the pocket.

[0039] The sealing portion seals the distal end portion of the tubular portion.

[0040] It is understood that the open distal end portion of the tubular portion is taken and embedded in the edge of the pocket, between the two films. An advantage is that when said breakable connection is broken and the sealing portion is detached from the tubular portion of the cap, the liquid leaving the tubular portion remains confined between the first and second films, in the edge. In other words, said tubular portion remains sealed by the first and second films, and therefore by the edge of the pocket. The edge of the pocket then forms an additional means of sealing the tubular portion, preventing the liquid from escaping from the pocket despite the breakage of the cap. The container then has a double seal.

[0041] This reduces the risk of liquid escaping from the pouch when handling the cap to break the breakable seal, or in the event of the breakable seal being accidentally broken. In order to dispense the liquid, the user must then pierce the first film or the second film so that the open distal end portion of the tubular portion extends beyond the rim. The distal end portion of the tubular portion is then no longer blocked by the films and the liquid can be dispensed.

[0042] Preferably, the first film or the second film can be pierced using the end portion of the tubular portion of the plug.

[0043] Preferably, said cap further comprises a fixing base fixed to the bag and to which said tubular portion of the cap is connected, said tubular portion of the cap extending between the closure portion and said fixing base. The fixing base allows the cap to be fixed to the bag and in particular to the two films. The fixing base also makes it easier to hold the cap. In particular, by holding the fixing base with one hand and exerting force on the closure portion with the other hand, the user can easily break the breakable connection and detach the closure portion from the tubular portion.

[0044] Said fixing base advantageously has a cylindrical shape. It advantageously extends in the main direction of the plug. The fixing base advantageously has an elliptical, or eye-shaped, section.

[0045] The tubular portion of the plug advantageously has a proximal end portion fixed to said fixing base. Preferably, the tubular portion extends transversely from the fixing base.

[0046] Preferably, said fixing base is disposed between the first and second films. Preferably the fixing base is disposed in the edge of the pocket.

[0047] Advantageously, said fixing base has a through orifice opening on the one hand into the tubular portion of the stopper and on the other hand into the interior volume of the bag. Said fixing base therefore places the tubular portion of the stopper in fluid communication with the interior volume of the bag. When dispensing the liquid, the latter is brought into the tubular portion via said through orifice of the fixing base.

[0048] Advantageously, said fixing base is arranged in the edge of the pocket, between said first and second films of the pocket.

[0049] Preferably, at least one of the first and second films is welded to said fixing base. Preferably, the first and second films are welded to said fixing base of the cap.

[0050] Preferably, the fixing base is disposed at the liquid outlet. Preferably, the fixing base is disposed in the outlet opening defining the liquid outlet. Preferably, the fixing base substantially fills the entire outlet opening. Said fixing base advantageously partially closes the liquid outlet.

[0051] Preferably, the plug extends in a main direction and the fixing base of the plug has a section greater than a section of the tubular portion of the plug, considered transversely to said main direction of the plug. An advantage is to facilitate the gripping of the fixing portion, in particular when the user wishes to act on the sealing portion to break the breakable connection.

[0052] Advantageously, the fixing base comprises a hooking means configured to further facilitate the gripping of said fixing base. Preferably, said hooking means comprises at least one groove formed in a side wall of said fixing base.

[0053] Preferably, said base for fixing the cap has a face arranged in the interior volume of the pocket.

[0054] According to a particularly advantageous aspect, substantially the entire stopper is arranged in the edge of the pocket, between said first and second films of the pocket. It is understood that the stopper is embedded in said edge of the pocket. One advantage is to effectively secure the stopper to the pocket. Another advantage is to further improve the sealing of the tubular portion of the stopper, produced by said first and second films. The hermeticity of the container is therefore improved.

[0055] Additionally, because the cap extends into the pocket rim, it does not protrude from the pocket, reducing the risk of snagging and damaging the cap. The risk of injury from the cap is also reduced.

[0056] Advantageously, the stopper extends in a main direction and said closure portion of the stopper comprises a gripping portion having a transverse dimension, considered transversely to said main direction, greater than a transverse dimension of the tubular portion of the stopper. An advantage is to facilitate the gripping and handling of the closure portion in order to be able to break the breakable connection more easily and thus be able to easily detach the closure portion.

[0057] More preferably, the gripping portion has a transverse dimension, considered transversely to said main direction, greater than an external diameter of the tubular portion of the stopper.

[0058] Advantageously, said gripping portion comprises at least one fin. Said fin advantageously extends radially considered with respect to said main direction. More preferably, said gripping portion comprises two fins. The two fins advantageously extend in the same plane.

[0059] Preferably, the gripping portion has a substantially trapezoidal shape.

[0060] Preferably, said first and second films of the pocket are assembled together so as to further form at least one lateral edge for the pocket, extending from said edge of the pocket.

[0061] Preferably, said first and second films of the pocket are assembled together so as to further form a first lateral edge, and a second lateral edge for the pocket, extending from said border of the pocket. More preferably, said first and second films are assembled together so as to form an end edge for the pocket, opposite said border.

[0062] Advantageously, said pocket extends in a longitudinal direction, said edge having a width considered in said longitudinal direction, which is greater than or equal to a length of the cap.

[0063] The border preferably has a width of between 1 and 3 centimeters.

[0064] Preferably, said edge extends transversely to the longitudinal direction of the pocket. Preferably, said plug extends along said longitudinal direction of the pocket.

[0065] Advantageously, the pouch comprises an outlet opening formed in said border, between said first and second films, said outlet opening opening into the interior volume of the pouch and defining said liquid outlet, the plug being disposed at least partially in said outlet opening. Said outlet opening is formed between two portions respectively of the first and second films which are not assembled together. Said opening is advantageously formed between two edge portions respectively of the first and second films.

[0066] Preferably, said pouch has a filling opening opposite said liquid outlet. Said filling opening defines a liquid inlet for introducing liquid into the interior volume of said pouch.

[0067] Preferably, said filling opening is only used when packaging the container, to fill the bag with the liquid, in the case of a single-use container. This filling opening is then closed and resealed, for example by welding the first and second films together.

[0068] Alternatively, the filling opening can be closed with a closure that can be opened or closed at will, allowing the bag to be refilled when it is empty. One advantage is that the container can be reused once it has been emptied of its liquid. It is therefore reusable and does not have to be thrown away once emptied. The ecological impact is therefore reduced.

[0069] Alternatively and without departing from the scope of the invention, said filling opening may be closed by a closing element, for example by a membrane intended to be pierced.

[0070] Preferably, the container is a container intended to contain animal semen. Brief description of the drawings

[0071] The invention will be better understood on reading the following description of an embodiment of the invention given by way of non-limiting example, with reference to the appended drawings, in which: [ Fig. 1 ]there figure 1 shows a container according to the invention, comprising a pocket and a breakable cap; [ Fig. 2 ]there figure 2 shows a cap of the container of the figure 1 ; [ Fig. 3 ]there figure 3 shows the cap of the figure 2 seen from below; [ Fig. 4 ]there figure 4 illustrates the arrangement of the cap of the figure 2 in the edge of the pocket; [ Fig.5 ]there Figure 5 shows a step of breaking the breakable bond of the container cap of the figure 1 ; [ Fig. 6 ]there figure 6 shows the piercing of a film of the pocket by means of the stopper; and [ Fig. 7]there figure 7 shows the container of the figure 1 , the sealing portion having been detached from the tubular portion. Description of the embodiments

[0072] The invention relates to a container for a liquid, the container comprising a bag and a cap. The container is particularly suitable for containing animal semen, for the purpose of carrying out animal insemination, for example porcine.

[0073] A non-limiting embodiment of a container 10 according to the invention is illustrated in figures 1 to 7 .

[0074] On the figure 1 , we note that the container 10 includes a pocket 20 and a cork 40 breakable attached to the pocket 20.

[0075] The pocket 20 has a generally rectangular shape and extends in a longitudinal direction L. It includes a first film 22 and a second film24 substantially identical. The first and second films 22,24 have a generally rectangular shape. They are flexible and made of a plastic material, preferably transparent.

[0076] The first film 22 includes a first edge 22a, a second edge 22b, a third edge 22c and a fourth edge 22d. Likewise, the second film 24 comprises a first edge, a second edge, a third edge and a fourth edge, not visible on the figure 1 .

[0077] The first and second films 22,24 arranged one above the other and are assembled along their perimeter, so as to form the pocket. More precisely, the first edges 22a first and second films are assembled together to form a border 20a for the pocket 20. The second edges 22bfirst and second films are assembled together to form a first side edge 20b for the pocket 20. The third edges 22c first and second films are joined together to form an end edge 20c for the pocket 20. Finally, the fourth edges 22d first and second films are assembled together to form a second side edge 20d for the pocket 20. Without limitation, the first and second films 22,24 are assembled here by welding.

[0078] The pocket 20 has an interior volume V set between the first and second films 22,24 and intended to receive a liquid.

[0079] The pouch includes a filling opening 26, formed in the end edge 20c from the pocket 20, between two portions of the first and second films respectively 22,24which are not assembled together. This filling opening 26 allows the bag to be filled with liquid during packaging. Once the bag is 20 filled, this filling opening is advantageously closed by a weld 27 between the first and second films 22,24 allowing said filling opening to be closed 26. In this non-limiting embodiment, the container is for single use.

[0080] The pocket also includes a liquid outlet 28 defined by an outlet opening 30. The exit opening 30 is formed in the border 20a from the pocket 20. More precisely, the exit opening 30 is formed by a portion of the first edge 22a from the first film 22 and a portion of the first edge of the second film 24 which are not assembled.

[0081] As can be seen on the figure 1 , the container 10 further includes a stopper 40 arranged in the outlet opening 30, at the liquid outlet 28.

[0082] Referring to the figure 2 , we see that the cork 40 extends in a main direction Y which is confused with the longitudinal direction L from the pocket 20. In other words, the cork 40 extends in the longitudinal direction Y from the pocket 20. The cap is made of hard plastic material. It has a length THE.

[0083] The cork 40 includes a hollow tubular portion 42. This tubular portion 42 extends along the main direction Y of the cork 40. It has a proximal end part 42a and a distal end portion42b. This tubular portion 42 is in fluid communication with the interior volume V of the pocket, so that liquid can enter it.

[0084] The cork 40 also includes a sealing portion 44. The shutter portion 44 has a gripping portion 46 trapezoidal in shape and comprising a first fin 48 and a second fin 50. The first and second fins 48,50 extend in the same plane, radially relative to the main direction Y of the cap. The gripping portion 46 facilitates the grip and manipulation of the shutter portion 44.

[0085] The shutter portion 44 is full. It extends in the extension of the tubular portion 42 and is connected to the tubular portion 42 by a breakable bond 52.This breakable bond 52 can be broken manually by a user, without tools and with minimal effort.

[0086] The tubular portion 42 has a length, considered according to the main direction Y of the stopper, approximately equal to two-thirds of the length of the stopper. The sealing portion 44 has a length, considered according to the main direction Y of the cork, approximately equal to one third of the length of the cork.

[0087] When connected to the tubular portion 42, the sealing portion 44 closes said tubular portion and prevents the liquid from escaping from the container 10 via the distal end portion 42b of the tubular portion 42.

[0088] As illustrated in figure 2 , the cork 40 further includes a mounting base 54. The tubular portion 42is fixed to said fixing base 54 and extending transversely to this fixing base. The fixing base 54 has a cylindrical shape and an elliptical, or eye-shaped, section. The fixing base 54 also extends along the main direction Y of the cap. The cylindrical portion 42 is arranged between the fixing base 54 and the sealing portion 44.

[0089] As illustrated on the figure 3 , showing the cap 40 seen from below, a through hole 56 is provided in the fixing base 54 according to the main direction Y of the cap. The through hole 56 opens on the one hand into the tubular portion 42 of the cork 40 and on the other hand in the interior volume V from the pocket 20. This through hole allows the tubular portion to be placed42 in fluid communication with the interior volume V from the pocket. The fixing base 54 also has a face 57 arranged in the interior volume V from the pocket 20.

[0090] Referring again to the figure 2 , we see that grooves 58 are arranged in a first side wall 60 of the fixing base. These grooves 58 define means of attachment facilitating the handling of the mounting base and more generally of the cap 40. In a non-limiting manner, the fixing base further comprises a second, non-visible side wall, in which grooves are also provided.

[0091] The shutter portion 44, the tubular portion 42 and the fixing base 54 form a single piece.

[0092] As illustrated in figure 4, the cork 40 is arranged in the border 20a from the pocket 20 and spans between the first and second films 22,24, in which he is caught and drowned.

[0093] The fixing base 54 is arranged in the outlet opening 30, between the first and second films. It is sandwiched between the two films 22,24 for fixing the cap 40 in the pocket 20.

[0094] According to the invention, the sealing portion 44 of the cork 40 is arranged in the border 20a from the pocket 20, between the first and second films 22,24. Said sealing portion 44 is therefore drowned in the border 20a. An interest is to maintain said obturation portion integral with the pocket, even though the obturation portion 44 would be detached and separated from the tubular portion 42.

[0095] Here, the shutter portion 44 of the cap is welded to the first film 22 and the second film 24. Likewise, the fixing base 54 is welded to the first and second films 22,24.

[0096] Likewise the tubular portion 42, and in particular its distal end part 42b is placed in the border, between the first and second films 22,24.

[0097] The border 20a from the pocket 20 presenting a width l considered according to said longitudinal direction L, which is greater than the length Lc of the cork 40.

[0098] The operations for distributing the liquid contained in the bag 20 of the container 10 will now be described with reference to figures 5 to 7 .

[0099] Initially, the liquid is contained in the pocket20 and the sealing portion 44 is connected to the tubular portion 42 of the cork 40 by the breakable bond 46. The shutter portion 44 the cap closes the tubular portion 42 and the liquid cannot escape from the pocket 20 via the tubular portion.

[0100] Firstly, as illustrated in Figure 5 , the user grasps the gripping portion with one hand 46 of the sealing portion 44. In a non-limiting manner, it includes the fixing base here 54 of the cork 40 with his other hand. The user then tilts said obturation portion relative to the tubular portion 42 of the stopper. This force exerted on the sealing portion makes it possible to break the breakable connection 52. Therefore, the said sealing portion 44 is detached from the tubular portion 42and is no longer connected to said tubular portion. The sealing portion then no longer seals the tubular portion 42.

[0101] Thanks to the invention, as it is arranged in the border 20a, between the first and second films 22,24, the sealing portion 44 remains attached to the pocket 20, drowned in the border 20a, even after breaking the cork. The sealing portion 44 does not remain in the user's hands so that the user is not encumbered by this obturation portion. In addition, the obturation portion 44 does not risk falling on the ground, thus reducing the pollution caused.

[0102] After breaking the breakable bond, the distal end portion 42b open of the tubular portion 42 is no longer blocked by the blocking portion 44.The liquid is not, however, distributed to the extent that said distal end portion 42b of the tubular portion 42 is arranged in the border 20a from the pocket, between the first and second films 22,24. The first and second films define a sealed volume around said distal end portion 42b of the tubular portion, in which the liquid is confined, and from which the liquid cannot escape. In other words, said border and more precisely the first and second films 22,24 close the tubular portion 42 and prevent the distribution of liquid, even after breaking the breakable bond 52 of the cork.

[0103] In order to dispense the liquid, the user then tears or pierces the first film 22 and / or the second film 24, preferably by pushing the distal end portion 42b of the tubular portion 42of the cap through said film, as illustrated in figure 6 .

[0104] Therefore, as we can see in figure 7 , an opening is formed in the first or second film 22,24. Also, said distal end portion 42b of the tubular portion 42 of the plug is released and in fluid communication with the external environment. The internal volume V of the pocket is put in fluid communication with the external environment, via the tubular portion of the cap 40. The liquid is no longer confined. Preferably, the distal end portion 42b of the tubular portion 42 the cap then extends out of the rim 20a and is no longer arranged between the first and second films 22,24. Preferably, more than two-thirds of the tubular portion remains disposed within the border. 20a, between the first and second films

[0105] The user can then extract the liquid from the pocket 20, via the through hole 56 of the fixing base 54 and via the tubular portion 42 of the stopper. The liquid is dispensed from the distal end portion 42b of the tubular portion. The liquid is advantageously extracted by squeezing the pocket.

[0106] Once emptied of its liquid, the container can be thrown away.
