However, in many cases an opening device cut or cut in this way does not have satisfactory properties, which means that the liquid food contained in the package cannot be handled in a satisfactory manner. unsatisfactory pouring of the food. the opening device is not resealable. This is particularly In some cases, the opening device allows In other cases, a problem is in the case where the package is made of a flexible material, such as plastic film.

To solve this problem, the package can be manufactured with a device integrated therein. This can be provided with a screw cap specially designed opening or with an otherwise openable lid. The opening device can also be shaped in such a way that satisfactory pouring properties are obtained. Finally, the opening device can also be designed in another way to achieve the desired property.

However, the manufacturing process for producing such packages provided with specially designed opening devices is rather complicated. This, together with the cost of the opening device itself, means that the production cost for each package becomes rather high.

Thus, there is also a need for a disposable type packaging which, at a reduced manufacturing cost, allows for satisfactory handling of a liquid food or medicine contained therein.

SUMMARY OF THE INVENTION A first object of the present invention is thus to provide a packaging system which allows satisfactory handling of a liquid food or medicament contained in packages.

The packaging system must advantageously allow easy handling of liquid food for children, such as gruel.

Qcc! A second object of the present invention is to provide a method which allows satisfactory handling of a food or medicament contained in disposable packages. In order to achieve the first object, in accordance with the present invention, a packaging system with the features specified in claim 1, a connector with the features specified in claim 7 and a package with the features specified in claim 20 are provided. Preferred embodiments of the packaging system are set out in claims 2-6, preferred embodiments of the connector are set out in claims 8-19 and preferred embodiments of the package are set out in claims 21-25.

In order to achieve the second object, in accordance with the present invention, a method with the features stated in claim 26 is provided.

More particularly, in accordance with the present invention, there is provided a packaging system for a liquid food or medicament, which packaging system is characterized by disposable portion packages containing the liquid food or medicament and a reusable connector which is connectable to an opening means of a such packaging and via which the liquid food or medicinal product can be discharged from the packaging.

In this way, a packaging system is provided comprising disposable portion packages of the disposable type, which packages can be used together with a reusable connector. The connector provides an opening with the desired properties with each package, such as good pourability or resealability. The opening member of each package thus does not need to be designed to achieve these properties, which of course reduces the manufacturing cost of each package. The opening member of each of said packages preferably has a sealed, cut-out projection which can be opened by cutting or the like, which in its ice-open condition forms a channel-shaped opening communicating with the interior of the package. The connector is preferably insertable and fixable in the channel-shaped opening of each package. For fixing the connector in said channel-shaped opening, it here advantageously comprises a fastening member, which may comprise an expansion member, which when actuated is arranged for increasing its diameter.

According to a preferred embodiment of the packaging system according to the invention, the connector comprises a suction device, wherein a food or medicine contained in a package can be challenged by applying a suction over the suction device of a connector connected to said package. In this way, a packaging system is created which, for example, allows the distribution of a liquid food for children, such as gruel, which food can be distributed ready-mixed in disposable portion packages. When consuming the food contained in a package, the connector is arranged in the opening means of the package, after which it can be offered to a user, such as a child, after possible heating in a microwave oven. The user can then consume the food by applying a suction over the suction device. The packaging system according to the invention thus offers extremely easy handling of the food. All mixing work is eliminated. Furthermore, the washing work is significantly reduced. All that needs to be washed is the reusable connector.

Furthermore, in accordance with the present invention, a connector is provided for disposable type packages for a liquid food or medicament, which connector is characterized by a substantially tubular and at both ends open piece, which internally delimits a flow path, and one on said piece fastening means, wherein an end portion at a first of the two ends of the piece is insertable into a channel-shaped opening of each package and wherein the fastening means is closing means can be used for several packages. i i 5.1.5 9%? operable for fixing the connector in said opening.

As a result, a reusable connector is provided which can be connected to disposable type packages, which packages have a channel-shaped opening.

The connector delimits a flow path, which in the mounted condition of the connector puts the interior of the package in flow connection with the environment. The connector is reusable, which means that one and the same device can be manufactured without an opening device specially integrated therein. This is of course economically and also environmentally beneficial.

The connector can further be designed in the desired manner to achieve any property, such as, for example, good heel properties, resealability, etc.

The piece advantageously has a cross-section along at least a part thereof and preferably also a shape tapered towards the first end. In this case, for example, a cylindrically shaped piece can have a chamfer at said first end. As a result, a connector is provided which is easily insertable into the channel-shaped opening of the package.

Preferably, the clamping means of the connector comprises an expansion device, which is operable to increase the diameter thereof. The extender may in this case comprise a ring of an elastic material, which ring is arranged outside the piece, and a screw member, which is arranged outside and is arranged for threaded engagement with the piece, which screw means is attachable to said ring by rotation. . By turning the screw member, this will thus be applied to the ring, which is thereby forced to expand in the radial direction under the influence of the pressing force. By ensuring that this expansion takes place when the ring is inserted into the channel-shaped opening, a reliable fixing of the connector in the opening is achieved. According to a preferred embodiment of the connector according to the invention, this comprises an openable lid arranged at a second of the two ends of the piece.

In this way, the previously mentioned resealability is achieved. The said other end can in this case have an external thread and the cover can have an internal thread, which is complementary to the said external thread, which cover. thus, it can be screwed onto said piece to close the other end of the piece.

According to a further preferred embodiment of the connector according to the invention, it comprises an end sleeve arranged at the other end of the piece and a screw member screwable thereto, which end sleeve has an end wall with an opening accommodated therein at a radial distance from the center of the end wall and a central projection. screw means have a centrally arranged, through-discharge opening complementary to said projection, said projection being insertable into said recess by screwing the screw member. When screwing the cover, the projection will thus be fitted in the discharge opening of the screw member, whereby the opening is closed. By screwing on the lid, a connection is established between the flow path and the surroundings via the opening in the end wall and the central, through-through discharge opening.

According to a further preferred embodiment of the connector according to the invention, this comprises a suction device arranged at the other end of the piece and communicating with the flow path. The suction device is hereby arranged for dispensing a liquid food or medicine contained in a package connected to the connecting device by applying a suction over the same. In this way a connector is provided which is particularly suitable for use together with disposable type packages containing ready-mixed gruel or the like. The user simply acquires such a package, and if necessary, connects the connector to the package. 959 7 The contents are then ready for consumption after possible heating in the microwave oven. The conventional mixing work for preparing gruel in powder form and most of the conventional washing work of baby bottles has consequently been eliminated.

The suction device advantageously comprises a cover made of an elastic material, such as rubber, with a bulge, in which a discharge opening is accommodated.

Furthermore, in accordance with the present invention, there is provided a disposable type package for a liquid food or medicament, which package is made of a flexible material, such as a plastic film, has an opening member and is of a disposable type, which package is characterized by that the opening means comprises a protrusion which can be opened by cutting or the like, which in its opened state forms a channel-shaped opening communicating with the interior of the package, to which the connecting device as above is connectable.

In this way a package is produced, which can be used for distribution of a liquid food or medicine and which has a simple manufacturable opening device. This is designed as a projection, which by cutting, tearing or the like forms a channel-shaped opening, into which the connecting member can be inserted. The opening member thus does not need to be designed so that the required properties, such as good durability and resealability, are obtained. These properties are provided instead by the connector.

According to a preferred embodiment of the package, the opening means has an inner surface with a knurled structure, the opening means being advantageously formed by two opposite projecting portions of two opposite, side panels sealed along their side edges, a first of the side panels on its inner surface having longitudinal grooves a second of the side panels on its inner surface has angled grooves relative to the grooves formed on the opposite surface. 10 pÃ5gr5,19E59 8 The side panels are thereby easily separable to form the channel-shaped opening after cutting, tearing or the like of the opening member.

The liquid food contained in the package is an advantageous food intended for children, such as gruel, and the package allows advantageous heating of the liquid food contained therein by means of a microwave oven.

Finally, in accordance with the present invention, there is provided a method of connecting a connector to a package for a liquid food or drug, which method is characterized by the steps of opening or similarly opening an opening member of the package, which is a of a flexible material made of disposable portion packaging, which opening means in its opened state forms a channel-shaped opening communicating with the inner package, to then insert the connector into said opening, which connector internally delimits a flow path open at both ends, and finally fixing the connector in said opening. This results in a method that allows extremely easy handling of liquid foods or drugs. The food or medicine is procured in a disposable package. The reusable connector is then applied in a channel-shaped opening in the package. This connector can be designed in a suitable way to achieve the desired property, such as, for example, good heel properties.

Description of exemplary embodiments The present invention relates to a packaging system and to connectors 1 and packages 20 included therein.

The packages are disposable and intended for liquid foods or medicines.

The concept of liquid food also includes viscous food, such as ketchup. 915.9 As an example of a suitable liquid drug can be mentioned different types of nutritional solutions.

In the following, a number of packaging systems according to the invention will be described. Details and components with a similar function have consistently been given the same reference designation. The various packaging systems will mainly be described as reference to different types of liquid foods, but as previously stated, the present invention is also applicable to different types of liquid drugs.

In Fig. 1, the first embodiment of a connector 1 in accordance with what is now referred to, a invention is illustrated, which connector 1 is intended for a first embodiment of a packaging system according to the invention.

The connector 1 comprises a tubular, substantially cylindrical piece 2, which thus internally delimits a flow path 3 open at both ends.

The piece 2 has a chamfer 4 at a first end and an adjoining end portion 6. The piece 2 thus obtains a shape tapered towards the first end 5.

In the middle of the piece 2 a fastening member in the form of an extension member 7 is arranged. The expanding member 7 comprises a sleeve-shaped ring 8 of an elastic material, such as rubber, which ring 8 is arranged around the piece 2.

An end 9 of the ring 8 abuts against a circular ledge which is formed substantially in the middle of the piece 2.

The piece 2 has circumferential projections 11 adjacent to the ledge 10, which act for retaining the ring 8 arranged externally about them. The expansion member 7 further comprises a sleeve-shaped screw member 12, which is arranged externally about the piece 2 at a the set 10 facing end 13 of the ring 8. The screw member 12 is arranged for threaded engagement with the piece 2 and for this reason has an internal thread 14. The piece 2 has a complementary formed external thread 15. By turning the screw member 12 this is thus attachable. against 10 ll ring 8, which will thus be pressed against the ledge. The ring 8 will in this case, under the influence of the pressing force, expand in the radial direction.

The connector 1 finally also comprises a cover 16, which is arranged at a second 17 of both ends of the piece. The cover 16 is arranged for threaded engagement with the piece 2 and for this reason has an internal thread 18. The piece 2 has a complementary formed external thread 19. The cover 16 is thus screwable on said second end 17 for closing the flow path 3.

In Figs. 2a-d, to which reference is now also made, the method for connecting the above-described connectors 1 to a package 20 included in a first embodiment a packaging system also comprising said connectors 1 is illustrated.

The disposable package 20, which is made of a flexible material, such as a plastic film, has an opening means in the form of a projection 21. This projection 21 delimits a flow channel which is closed at one end and which at the other end is in flow communication with the interior of the package 20. The package 20 comprises two side panels 22, 23 and a bottom panel 24, which along their side edges are welded together to delimit a chamber, the volume of which depends on the position of the panels 22, 23, 24 relative to each other. The projection 21 is formed by two projecting portions 25 and 26 of the side panels 22 and 23, respectively.

Each projecting portion 25, 26 has a grooved structure on a surface 27 and 28, respectively, which face each other. As can be seen from the detail enlargement in Fig. 2b, the knurled structures comprise longitudinal grooves 29 on one 27 of the surfaces and slightly inclined grooves 30 on the other 28 of the surfaces. When the knurled structures 29, 30 are applied to each other, they will be slightly angled relative to each other.

Fig. 2a shows how the opening means of a package 20 filled with a liquid food is opened by means of n5 n. n o now 12 of a pair of scissors 31 and of Fig. 2b shows how a channel-shaped opening 32 is thereby formed.

More specifically, the channel-shaped opening 32 is formed. by separating the two projecting portions 25, 26.

This separation is facilitated by the knurled structures 29, 30, which prevent the facing surfaces 27, 28 of the projecting portions 25, 26 from adhering to each other.

The first end 5 of the connector 1 and the end portion 6 adjoining it are thus insertable into said channel-shaped opening 32.

When the connector 1 is inserted sufficiently far into the opening 32, the expansion means 7 for fixing the connector 1 in the opening 32 is actuated. More specifically, the screw means 12 for moving the same is rotated in the direction of the ring 8 for expanding it in the radial direction. The expansion then takes place in the channel-shaped opening 32, whereby the desired fixing of V is achieved.

The closure device 1 is hereby connected to the package 20 and for pouring a food contained in the package, the lid 16 is removed, as shown in Fig. 2d.

The package 20 of this first embodiment of the packaging system according to the invention is particularly suitable for liquid foods such as milk or jos.

The packages 20 of course allow filling under aseptic conditions.

It will be appreciated that both the package and the connector can be designed in other ways and thereby become other embodiments of packaging systems according to the invention.

In Fig. 3, to which reference is now made, a second embodiment of a connector 1 is illustrated in accordance with the present invention. The connector 1 differs from the connector 1 shown in Fig. 1 in that the cover 16 has been replaced by a suction device 33.
