Definitions
- the present invention relates to a container as well as a method and a device for producing the same. More specifically, the invention concerns a container for liquid contents, comprising a compartment which is defined by flexible walls and whose volume is dependent on the relative position of the walls, the walls having rim portions which engage each other and along which the walls are joined with each other in a common connecting por- tion, and a corresponding method and device for producing such a container.
- Containers of the above type are known from, for instance, W099/41155.
- a problem associated with this type of container relates to the actual production process.
- the containers usually have a decorative print on their out- side, and as a rule this print is applied to the webs of material, from which said containers are to be produced.
- this print is applied to the webs of material, from which said containers are to be produced.
- the different webs of material must be joined with great accuracy to ensure the requisite pattern alignment.
- sealing together the webs of material in said connecting portions requires that a sealing tool be pressed down to the joined webs of material.
- the web of material must be stopped, thus causing intermittent operation which is unfavourably time-consuming.
- a container for liquid contents comprising a compartment which is defined by flexible walls and whose volume is dependent on the relative position of the walls, the walls having rim portions which engage each other and along which the walls are joined with each other in a common connecting portion, which container is characterised in that the walls are made in one piece, which is folded to form said walls, and that the walls along said rim portions are sealed to form said connecting portion.
- the piece is folded to form a container comprising two opposite side walls and a bottom wall, by means of which the side walls are joined with each other.
- a method for producing containers is provided, which each have a compartment which is defined by flexible walls and whose volume is dependent on the relative position of the walls, which method if characterised by the steps of converting a web-shaped container material into a longitudinally folded web having at least one fold along one long side of the folded web, sealing together opposing surfaces of the web along succeeding connecting portions, each connecting portion forming a curve having a starting point and an end point along said at least one fold and being of an extent which essentially corresponds to the shape of a finished container.
- Fig. 3 is a schematic perspective view of a first preferred embodiment of an inventive device for producing containers .
- the bottom wall 3 separating the two side walls 2 from each other is, in the flat state of the container 1, in a state folded in two, which is clearly to be seen in Fig. 2.
- the cross-section of the empty and flat container 1 as shown in Fig. 2 illustrates the side walls 2 slightly separated for better clarity.
- FIG. 3 illustrates a first preferred embodiment of an inventive device 10 for producing the container 1 shown in Figs 1-2 from a web-shaped container material 11, which in the shown embodiment is supplied as a roll.
- the container material 11 is passed via deflecting rollers 15 to a nip 16 of the pair of rollers 14, which is arranged perpendicular to the container material 11.
- the material 11 is folded while the engaging means engage the same to form a longitudinally W-folded web 17 with two folds 18 along one long side 19 of the folded web 17. Consequently, it is a thus W-folded web 17 that is introduced into said nip 16, a guiding wheel 20 ensuring that the W folding is continuously uniform.
- the profile means 21 carries on its circumferential surface a plurality of profiles 23, which each are of an extent that essentially corresponds to the connecting portion 6 of the finished container 1.
- the nip means 22 forms together with said profile means 21 a nip 24 and comprises an ultrasonic means 25.
- the container material 11 advan- tageously comprises a sealing layer on its inside-forming surface, which sealing layer has a relatively low melting point, thereby ensuring that sealing only takes place where sealing is desired.
