Definitions

  • the present invention concerns a bag for storing fluids/liquids which are only to be mixed in immediate connection with use/discharge from the bag, preferably for storing and injecting animal semen, and which is made of two layers of plastic film, e.g. built up as laminates, of which one laminate on the side facing the other plastic film includes a weldable plastic, and where by a bag edge there is provided a discharge opening at an opening closure, preferably for taking out liquid via a catheter.
  • the bag may be produced by welding plastic film.
  • a film sheet can be folded and welded on three sides whereby a closed bag appears.
  • Two film sheets may correspondingly be welded on four sides whereby a closed bag appears.
  • Such bags may be opened by cutting off a welding by breaking a zipper closure with engaging zipper parts at opposite bag sides or by peeling a peelable closure.
  • the invention also concerns uses of such a bag.
  • a bag of the type mentioned in the introduction is e.g. known from US patent no. 5,725,312.
  • a closing arrangement for a film bag where a peelable closure and a reclosing mechanism are provided.
  • the materials providing peelable properties are welded on the film material, and the material may be built up from several different types of polymers so that adhesion and peeling properties are provided where desired.
  • sealed bags are often used as packing. These bags are to be opened quickly without using sharp instruments, e.g. a pair of scissors. It is a wish that a predetermined edge of the bag is to be opened, and it is achieved by substituting the welding with a gluing with a peeling wax.
  • Such wax is usually applied as a web on one of two mutually facing surfaces of a film sheet, and by passing welding rollers, a tight joining is performed which appear as a welding, but which can be separated again by tearing the outermost ends of the film pieces located outside the gluing.
  • a bag being peculiar in that the bag is formed with at least two mutually connectable compartments, as the two layers of plastic film are joined by strip-shaped weldings that over a part of their length may be torn up considerably easier than over the remaining part of their length, as first compartment, which communicates with the discharge opening, contains a first liquid, whereas a second liquid is contained in the second compartment, and that in the closing zone there is formed a first peelable joint of the welding, and that in the connection between the at least two compartments there is formed a second peelable joint of the welding.
  • the peelable joint of the welding can be provided according to different principles that enable use of different force for peeling the welding. It may thus occur by applying wax layer, by welding in a strip, by modifying the plastic or by controlling the welding temperature and thereby attain greater or lesser strength in the welding in the area where an easier peelability is wanted than in the remaining part.
  • compartments of the bag can be dimensioned according to the fluids to be used, it is possible to minimise the amount of fluid to be supplied with preservatives or treating agents, e.g. penicillin.
  • the bag is peculiar in that the first and second peelable joints of the welding includes embedded laminates in strip shape in parallel with the bag edge where the mouth is provided, as the first laminate is provided closer to the bag edge than the second laminate.
  • the bag is peculiar in that the laminates in the embedded strips consist of three layers, as a first outer layer is a low density polyethylene, the centre layer is a high density polyethylene with greater rigidity, and a second outer layer is a low density polyethylene which is modified for the purpose of peeling after passing a welding station.
  • peelability is understood in this connection that the two types of plastic film, e.g. built up as laminates, i.e. several different layers of material, are joined so that when the two plastic films are pulled from each other, the closure is broken in predefined zone without tearing the two films.
  • the bag includes a strip consisting of three layers, where a first outer layer is a low density polyethylene, the centre layer is a high density polyethylene with greater rigidity, and the second outer layer is a low density polyethylene which is modified for the purpose of peelability after passing a welding station, a greater stiffness is attained, entailing that the bag is easier to get hold of.
  • a first outer layer is a low density polyethylene
  • the centre layer is a high density polyethylene with greater rigidity
  • the second outer layer is a low density polyethylene which is modified for the purpose of peelability after passing a welding station, a greater stiffness is attained, entailing that the bag is easier to get hold of.
  • the plastic film materials are e.g. built up as laminates where the film can have different properties at each side. Furthermore, these films are e.g. made by co-extrusion of polymer materials.
  • the bag may advantageously be used for storing fluids/liquids for use with insemination of animal semen, preferably boar semen.
  • a first compartment communicating with the discharge opening contains a liquid with a greater part of semen cells than a liquid contained in the second compartment.
  • first peelable joint is broken before the second peelable joint, as the contents of the first compartment is discharged before the second peelable joint is torn up.
  • Fig. 1 illustrates a bag 1 which is made of the two layers of plastic film that are illustrated in Fig. 14.
  • Fig. 14 is seen that two layers of plastic film 2, 3 are superposed, and that between the two plastic films 2, 3 there is provided a peelable material 4.
  • the bag sides 2, 3 may be provided as a multi-layer films or single-layer films. In all cases, at least the laminate or the bag side facing the other plastic film is to include a weldable plastic.
  • the peelable material 4 may be provided in strip form extending from bag side to bag side, or alternatively be provided punctiform in areas between the two layers of plastic film where breaking a weld is desired to be established during use.
  • Fig. 1 illustrates that by a bag edge 5 there is provided a discharge opening 6.
  • the discharge opening 6 is provided with a duct 7 which has a tapering cross-section from the bag edge 5 towards a first compartment 8 in the bag.
  • the duct 7 has funnel-shaped inlet opening 9 that enable easy insertion of a catheter, and the catheter will be disposed with tight fit in the tapering duct 7 which is dimensioned so that the catheter does not penetrate into first chamber 8.
  • the two plastic films 2, 3 are joined with a series of strip-shaped weldings 10 so that besides the first compartment 8, a second compartment 8' is formed which is separated from the first chamber.
  • the bag can be designed with more than two compartments if the intended use necessitates storing three or more components independently of each other and performing mixing of these only in immediate connection with use of the formed product.
  • first and a second strip 11, 12 that provide the weldings 10 becoming peelable within the strip-shaped area.
  • the welding 10" located within the strip 11 and covering the discharge opening 6 may thus be broken more easily than the remaining part of the welding 10.
  • the welding 10' which is located at a connection between the two compartments 8, 8' within the area of the strip 12, will provide a peelable joint of the welding in this area so that there may be established a communication between the two compartments 8, 8'.
  • Such a use is particularly advantageous by an insemination.
  • the most semen-rich liquid will be disposed in the first chamber 8 and will be injected first at the insemination. Then liquid from the second chamber 8' can be used as propelling liquid when the second peelable joint of the welding 10' is peeled.
  • the bag will be particularly suited for injecting boar semen by insemination of sows.
  • the second peelable joint is formed by two largely rectilinear parts 13, 14 that are disposed under an angle 15 in relation to each other so that a point 16 is formed.
  • This point will preferably be oriented into the second chamber 8' so that a special force concentration and a beginning breaking of the joint 10" at the point 16 is achieved.
  • strip-shaped laminates that run in parallel with the bag edge 5 where the discharge opening 6 is provided.
  • the first laminate 11 will thus be provided closer to the bag edge 5 than the second laminate 12.
  • Such a disposition of strip-shaped laminates is simple in production.
  • the strips 11, 12 will consist of a three-layered construction as one outer layer is a low density polyethylene, and the centre layer is a high density polyethylene with greater rigidity, and the other layer is a low density polyethylene which is modified with regard to peelability after formation of the weldings 10 in a welding station.
  • the films for the bag sides and the embedded strip-shaped laminates may consist of co-extruded laminate of polymer materials or polymer materials or of separate layers.
  • Fig. 2 shows an embodiment where the rectilinear parts 13, 14 have greater length and extend under a more acute angle 15 than shown in Fig. 1. Hereby is achieved a greater notch effect and greater assurance of breaking at the point 16 when the bag is squeezed.
  • Fig. 3 shows an embodiment where between the rectilinear part 13 and a welding 17 between the two chambers, a more acute angle 18 than the one illustrated in Figs. 1 and 2 is formed. Hereby it becomes possible to achieve breaking, either at the point 16 or at point 19 formed between the welding strips 13, 17.
  • Fig. 4 illustrates a further embodiment, where the rectilinear part 14 extends perpendicularly to the bag edge 5 and not under an angle in relation to the bag edge as the above mentioned embodiments.
  • Fig. 5 shows an embodiment that largely corresponds to the embodiment in Fig. 4, but here embedded laminates 20, 21 are illustrated that only extend in the area where peeling of the weld parts 10' and 10" is desired.
  • Fig. 6 shows an embodiment where welding strips 22 at the side edge of the bag have an inwards directed course for providing a better and more secure shape when the bag is gripped for squeezing.
  • Fig. 7 illustrates an embodiment corresponding to the one shown in Fig. 6, but the length of the rectilinear part 13 is slightly shorter in this embodiment.
  • Fig. 8 illustrates an embodiment that also has a narrowing centre part, and here the rectilinear parts 13, 14 are designed under an angle in relation to the bag edge 5 for forming the point 16.
  • Fig. 9 illustrates an embodiment corresponding to the one shown in Fig. 8, but the length of the rectilinear part 13 is slightly longer in this embodiment.
  • Fig. 10 shows an embodiment with narrowed centre part of the bag, and where the first rectilinear part 13' is formed by a rectilinear extension of the welding strip 17 and the second rectilinear part 14' extending perpendicularly thereto (in parallel with the bag edge 5). These two rectilinear parts 13', 14' are oriented under an angle 15' and form a point 16' which in this embodiment is directed into the first compartment 8.
  • Fig. 11 substantially corresponds to Fig. 10, but is here shown without a narrowing centre part on the bag.
  • Fig. 12 illustrates an embodiment corresponding to Fig. 10 but provided with a further weld strip 23 disposed inside the angle 15' with orientation into the second chamber 8'. With this embodiment, a breaking at each side of the weld strip 23 by squeezing the bag may be achieved.
  • Fig. 13 is an embodiment that substantially corresponds to the embodiment shown in Fig. 1 but with an angle 15 which is considerably greater than the angle 15 according to Fig. 1.
