Description
- The invention relates to a packaging for filling products that are capable of flowing and pouring, with a metering device for removing the filling product in portions.
- Pumping stations, which can be operated by hand and inserted in a container which is filled with the product, are predominantly used for the metered dispensing of portions of ketchup, mustard and the like in a small quantity of products to be dispensed in liquid, partially liquid or pasty form. Another common packaging consists of a cylinder which is filled with the product and from which the product is ejected in portions with a piston which can be operated by hand.
- The known packagings with metering systems often have hygiene problems. In addition, the rigid product containers often have a high proportion of material. The additional fittings, such as pumping stations or cylinder/piston systems, which are necessary in addition to the product container for the metered dispensing of the product, are a further drawback of the known packagings with metering systems.
- The invention is based on the object of providing a packaging of the type described at the outset, which does not have the drawbacks associated with the known packagings with metering systems.
- The object according to the invention is achieved by a main chamber for storing the filling product, a metering chamber connected to the main chamber by a first channel to provide filling product portions, and a second channel leading from the metering chamber to a dispensing opening and crossing the first channel, the main chamber, the metering chamber and the two channels being formed in a tube-like manner from a film-like, flexible packaging material and being limited by an arrangement of surface regions of packaging material which abut one another and are connected to one another by sealing.
- In a preferred configuration of the packaging according to the invention, the main chamber and the first channel between first film strips and second film strips which are sealed against one another, the metering chamber between first film strips and third film strips which are sealed against the first film strip, and the second channel between the third and second film strips which are sealed against one another, are formed from the film-like, flexible packaging material.
- In a packaging according to the invention which is suitable for continuous production, the first film strip is folded onto itself and sealed against itself and the third film strip is sealed against the folded part of the first film strip.
- In an alternative type of production, the main chamber, the first channel, the metering chamber and the second channel between first film strips and second film strips which are sealed against one another, are formed from the film-like, flexible packaging material. In this case, the first film strip may be folded onto itself and sealed against itself and the second film strip is sealed against the folded part of the first film strip.
- The first channel at an end opening into the metering chamber may be divided into two part-channels.
- In the ideal case, the two channels intersect at an angle of about 90°. The intersection angle may, however, also be smaller and, for example be 45° to 90°, preferably 80° to 90°.
- The packaging is preferably sealable on both sides.
- Packaging films, which can be sealed against one another and have a sealing layer on the side forming the inside and the outside in the finished packaging, or the insides and the outsides of which can be sealed against one another, are suitable as film-like, flexible packaging material to produce the packaging. The sealing layer in this case may be connected as a sealing film to a carrier layer by a laminating adhesive. The sealing layer may, however, also be applied to a carrier layer by extrusion coating or with an additional adhesion promoter layer by coextrusion coating. Under certain conditions, it is also possible to produce a sealing layer and a carrier layer by coextrusion. In certain cases, if the carrier layer is itself sealable, a separate sealing layer may also be dispensed with.
- The sealing layers are generally polyethylenes, for example LDPE, LLDPE, MDPE and mixtures thereof or coextruded, metallocene polyethylenes and ionomers, for example Surlyn®, or coextruded films made of these materials with PE as the carrier layer. Polypropylenes can also be used for special applications. The thickness of the sealing layers is in the range of 10 to 100 μm, preferably 15 to 75 μm.
- Suitable carrier layers are plastics material films made of polyester, polyethylene, polypropylene or polyamide. A preferred polyester is PET (polyethylene terephthalate) in a preferred thickness of 8 to 20 μm, in particular 12 μm. The plastics material film which is used as the carrier layer may be printed on the front and optionally provided with a top coat of varnish with good sliding properties or be reverse-printed.
- The plastics material film which is used as a carrier layer may be coated with a barrier layer against the penetration of oxygen, steam and flavourings. Suitable barrier layers are, for example, ceramic thin layers made of silicon oxides and/or aluminium oxide, which may be applied by sputtering or vacuum deposition, or plastics materials, for example made of materials from the series of vinyl alcohols, for example ethyl vinyl alcohol polymers or polyvinylidene chloride. Instead of one of the barrier layers mentioned, a foil made of metal, in particular from aluminium or an aluminium alloy may be used as the carrier layer.
- The individual films or film strips of the packaging, which form the walls of the main and metering chamber, may consist of the same or different materials and have the same or a different layer construction. However, the packaging preferably consists of the same packaging material.

In the present example, themain chamber 12 is formed from afront side 18 a andrear side 20 a in the form of a tubular pouch, the front andrear sides main chamber 12 being sealed against one another by firstlongitudinal sealing seams - At the transition of the
main chamber 12 into the tube-likefirst channel 16 connecting themain chamber 12 to themetering chamber 14, the firstlongitudinal sealing seams wider sealing faces first channel 16 into themetering chamber 14 as narrow secondlongitudinal sealing seams metering chamber 14. A furtherlongitudinal sealing seam 21 d, together with thelongitudinal sealing seam 21 c of themetering chamber 14, limits asecond channel 34 described in more detail below. - The
longitudinal sealing seams metering chambers packaging 10. The sealing region which is composed of parts of thelongitudinal sealing seams wider sealing faces transverse sealing seam 25 limiting themetering chamber 14 in a centre part M of the packaging between themain chamber 12 andmetering chamber 14 will also be designated below atransition sealing region 27. - As can be seen from
FIG. 3 , the tube-likefirst channel 16 in a region of the end opening into themetering chamber 14 is divided by ashort sealing seam 17 running approximately in a longitudinal axis of thefirst channel 16 into two part-channels first channel 16 into themetering chamber 14 means that the throughflow cross section, which increases with a thoughflow of filling product from themain chamber 12 into themetering chamber 14, decreases again more quickly with reducing pressure on themain chamber 12 and therefore further increases the effect of the outlet region as a check valve, so a backflow from themetering chamber 14 into themain chamber 12 is practically prevented. - Like the
main chamber 12, themetering chamber 14 is also formed from afront side 18 c and arear side 20 c in the form of a tubular pouch, the front andrear sides longitudinal sealing seams - A first
transverse sealing seam 24 connecting the firstlongitudinal sealing seams main chamber 12 on the side remote from thefirst channel 16. In the same way, a secondtransverse sealing seam 26 connecting the secondlongitudinal sealing seams metering chamber 14 on the side remote from thefirst channel 16. - A
first film strip 28 which is forming thefront side 18 a of themain chamber 12 extends from the firsttransverse sealing seam 24 closing themain chamber 12 up to the secondtransverse sealing seam 26 closing themetering chamber 14 and, over themetering chamber 14, forms afront side 18 c of themetering chamber 14. - A
second film strip 30 forming therear side 20 a of themain chamber 12 extends from the firsttransverse sealing seam 24 closing themain chamber 12 to approximately the height of the end of thefirst channel 16 opening into themetering chamber 14. - A
third film strip 32 forming therear side 20 c of themetering chamber 14 extends from the secondtransverse sealing seam 26 closing themetering chamber 14 to approximately the height of the transition of themain chamber 12 into thefirst channel 16 connecting themain chamber 12 to themetering chamber 14. - Arranged in the
transition sealing region 27 in the centre part M of the packaging between themain chamber 12 andmetering chamber 14, i.e. in the region of the wide sealing faces limiting thefirst channel 16 and being produced by the mutual sealing of thefirst film strip 28 and thesecond film strip 30, is a tube-likesecond channel 34 formed by sealing faces produced by the mutual sealing of thesecond film strip 30 and thethird film strip 32. - The
second channel 34 forms an outlet channel for the filling product to be dispensed by themetering chamber 14 from thepackaging 10 into the open and extends from an outlet opening 35 of themetering chamber 14 to adispensing point 36 at the end of thesecond channel 34 remote from the outlet opening 35 of themetering chamber 14. On the way from themetering chamber 14 to thedispensing point 36 of thepackaging 10, thesecond channel 34 crosses thefirst channel 16 approximately at right angles in anintersection point 37 in the embodiment shown. The crossing angle of the twochannels - As can be seen, for example, from
FIG. 1 , regions which are not required on thepackaging 10 that is ready for use are cut away from sealing faces. In particular, the tube-likesecond channel 34 is exposed toward its free end and thereby configured to be moveable out of the plane formed by the sealing faces. At a short spacing from its free end, the tube-like channel 34 is equipped withtear notches 38 as opening aids for easier opening. Obviously, thechannel 34 may also be opened by a cut with scissors placed transversely over thechannel 34. - In a method shown in
FIG. 5 to 10 for the continuous production of thepackaging 10 with a metering system, three partially overlapping film bands A, B and C which are made of packaging material are guided past processing stations, not shown in the drawing, and sealed against one another while maintaining the sealing geometries required to configure thechannels metering system 12. Thepackagings 10 which are connected in the flat position are then cut to final size and separated, it also being possible for these processing steps to firstly be carried out shortly before or after filling with filling product. - According to
FIG. 5 , a first film band A is fed. A second film band B and a third film band C rest on the first film band A and move at the same speed as the film band A through a sealing station, in which a sealing of the second film band B against the first film band A takes place with a first sealing geometry S1 shown inFIG. 7 and adapted to the configuration of the tube-likefirst channel 16 of themetering system 12 and to the configuration of the two first longitudinal sealing seams 19 a, 21 a. At the same time, a sealing of the third film band C against the first film band A takes place in the sealing station with a second sealing geometry S2, shown inFIG. 8 and adapted to the configuration of the tube-likesecond channel 34 of themetering system 12. - According to
FIG. 8 , the mutual position shown inFIG. 5 and the spacing of the two sealing geometries S1 and S2 with respect to one another are selected in such a way that after the folding of the film band A and sealing of the outside of the film band A against itself, the two sealing geometries S1 and S2 are located with respect to one another in such a way that the tube-like channels FIGS. 6 and 9 ). Simultaneously with the sealing of the film band A folded against itself, the two second longitudinal sealing seams 19 c, 21 c and the secondtransverse sealing seam 26 of the film bands A, C now located congruently on one another, inside to inside, are also sealed against one another in accordance with the third sealing geometry S3 shown inFIG. 10 . - After the filling of the
main chamber 12 with filling product, themain chamber 12 is closed by applying the firsttransverse sealing seam 24. - The packaging is opened by tearing away or cutting away an end part of the
channel 34 by an end consumer. By pressing together themain channel 12 by hand, under the pressure applied, filling product is pressed out of the main chamber through thefirst channel 16 into themetering chamber 24. In the normal case, themetering chamber 14 is completely filled to provide identical portion sizes. During this filling process, the tube-likefirst channel 16 is expanded to its maximum diameter and therefore prevents, at theintersection point 37 of the twochannels second channel 34 to its maximum diameter, i.e. the throughflow of filling product through thesecond channel 34 is practically prevented in this manner. As soon as themetering chamber 14 is filled with filling product from themain chamber 12, the content of themetering chamber 14 can be pressed out from thepackaging 10 by pressing together themetering chamber 14, for example between the thumb and index finger, via the tube-likesecond channel 34 and through the opening at the free end of thechannel 34. In this process, because of the sealing regions located in a plane, the opening of the free end of thefirst channel 16 opening into themetering chamber 14 remains practically closed and therefore prevents a backflow of filling product into themain chamber 12. The tube-likesecond channel 34 is also now expanded to its maximum diameter and therefore at the intersection point of the twochannels first channel 16 to its maximum diameter, i.e. the throughflow of filling product through thefirst channel 16 is thus practically prevented. - The
packaging 10 normally contains a filling product that is capable of flowing, in particular a liquid, partially liquid or pasty filling product. Ketchup, mustard, mayonnaise and similar foods may be contained as the filling product inpackagings 10. The use of the packaging is, however, not limited to foods, but rather comprises all types of filling products that are capable of flowing and pouring, such as, for example, creams in the field of cosmetics and lubricants, adhesives and technical products of this type in the field of technology. - The alternative production method shown in
FIGS. 12 and 13 differs from the method according toFIGS. 5 and 6 in that, instead of a third film band C, the second film band B is selected to be correspondingly wider and, in addition, amaterial loop 40 is arranged between the first sealing geometry S1 and the second sealing geometry S2. The secondtransverse sealing seam 26 is thus dispensed with. In a method variant, not shown in the drawing, the folding of the first film band A can be dispensed with in accordance with the arrangement shown inFIG. 2 to 4 , so that only a 3-layer composite is produced instead of a 4-layer composite in the central region M and therefore also in theintersection point 37 of the twochannels
