Definitions
- the invention relates to a container containing a moisture-crosslinking hot-melt adhesive, which is enclosed by a moisture-proof film bag.
- the invention particularly relates to a container which contains a moisture-crosslinking polyurethane hot-melt adhesive.
- adhesives are suitable for particularly high-quality adhesive bindings. They are characterized by very good adhesion properties and excellent strength. They are applied at around 120 ° C and, after cooling, react with the air humidity or the paper to form high-molecular, hardly fusible compounds.
- the high final strength is achieved through the chemical reaction of free isocyanate groups with surface moisture and with H-active chemical groups on the substrate surfaces.
- they are characterized by high chemical resistance, e.g. B. against printing ink oil, as well as high temperature and aging resistance. They require special melting and application equipment and a high processing effort.
- the bag consists of an aluminum foil laminated with polyethylene, whereby the aluminum ensures the tightness against air humidity.
- the user cuts the film with a knife and pulls the film off the solid product. Undercuts and, in particular, folds in the film are of considerable disadvantage, because in this case the film cannot be removed from the solid hot-melt adhesive block, or only with great difficulty. In addition, the foil bag cannot be completely emptied.
- the foil bag has a cylindrical shape with a flat circular bottom welded in at the bottom.
- this film bag is inserted into a cardboard tube in order to avoid wrinkling in the film jacket as far as possible.
- the film thickness of around 100 ⁇ m usually used, it is nevertheless not entirely possible to avoid wrinkles forming.
- the main disadvantage of the known container is the very high cost of its manufacture. On the one hand, such a film bag with an inserted flat circular bottom can only be produced manually, so that its production costs are relatively high.
- the almost cylindrical block of the hot melt adhesive is brought into a closed housing, which is under a protective gas, in particular nitrogen, whereby it rests on a The flat grate on the heating element rests.
- the product is heated at temperatures up to 170 ° C, so that the liquid hot melt adhesive drips down into the melt pool located below. From this melt pool, the adhesive is pumped to the application nozzles. It has previously been assumed that the product should have a flat lower floor so that the floor can be heated over its entire surface at the same time. Therefore, the above-mentioned foil bags with a flat bottom were used.
- the upper side of the adhesive blocks is curved in a lenticular shape (concave), so that the cavity thus formed between the upper side of the lower block and the lower side of the upper block encloses outside air with the corresponding harmful air humidity.
- the curvature of the top of the adhesive block is due to the contraction of the hot adhesive in the film bag during cooling at the adhesive manufacturer.
- the invention is therefore based on the object of developing a container of the type mentioned at the outset with improved production conditions and performance properties.
- its foil bags are said to be considerably less expensive and the risk of moisture access to the user should be significantly reduced.
- foil bags can be used than in the prior art.
- known stand-up pouches or stand-up pouches with an outwardly curved base are possible.
- the outwardly curved bottom of the block of adhesive freed from the film bag is better at the inwardly curved upper side of a previous block of adhesive in FIG Adjusted melting unit of the user, so that significantly less outside air is trapped with the harmful air humidity.
- Typical sizes of the containers according to the invention are about 2 kg, although larger bags of up to 20 kg or even more can also be used.
- the film bag is preferably designed, at least in the lower region, as a stand-up bag known per se. This bag is particularly inexpensive due to the automated mass production.
- the film bag have a casing part made of two congruent superimposed first films, which are connected to one another along their two longitudinal edges by longitudinal weld seams, and a bottom part which consists of a folds inwards when the film bag is not filled and with its edges opposite the folded edge the inside of the lower edges of the first two films of welded second film, and that the remaining edges of this second film are welded to the corresponding inner edges of the first two films.
- the second film which is still folded in when the film bag is empty, folds outwards when the film bag is filled, and in this way forms a base which is curved outwards.
- the two congruent superimposed first films move outwards so that they form an approximately cylindrical jacket, the lower edges of which form the contact surface or contact line of the film bag.
- the pouch When the empty foil pouch is delivered to the adhesive manufacturer, the pouch can be folded flat without creating folds or kinks.
- many folds and kinks occur when the bag is folded flat.
- the folds and creases lead to very small holes in the aluminum foil, which is then no longer completely waterproof.
- These disadvantages do not occur with the film bag according to the invention.
- the remaining edges of the second film are welded to the corresponding inner sides of the first two films in such a way that only a central segment-shaped part of each folded half of the second one is welded The film remains free of welding.
- a particularly stable contact surface of the filled foil bag is achieved if the inner sides of the lateral edges of the folded second foil are welded together.
- a particularly stable and practically wrinkle-free film bag is obtained if the thickness of the film is preferably 100 to 200 ⁇ m. This is the thickness of the entire composite film.
- the film is preferably a composite film made of aluminum film laminated on both sides with a plastic film.
- the plastic film is mainly used to protect the aluminum film, which is an absolute seal against the entry of water vapor. Removability also plays a role in the selection of the plastic film.
- the construction of the film bag also affects the rigidity of the film bag, e.g. the number and width of the webs created by the weld.
- the reactive hot melt adhesive is a moisture-curing polyurethane hot melt adhesive.
- FIG. 1a shows a top view of a first film as part of the film bag of the container according to the invention
- FIG. 1b is a top view of the second film, which also forms part of the film bag
- Figure 2 is a top perspective view of the bottom of a filled
- FIG. 3 shows a top view of the underside of a container according to the prior art
- FIG. 4 is a very schematic representation of the melting pool at
- Figure 5 shows a central longitudinal section through two superimposed
- Figure 6 shows a section through two superimposed adhesive blocks according to the invention.
- a composite film is used in this exemplary embodiment to produce a film bag which can be used for a container according to the invention.
- PET with a thickness of 12 ⁇ m is used as the outer layer
- aluminum foil with a thickness of 12 ⁇ m as the middle layer
- PE or PP with a thickness of 125 ⁇ m as the inner layer.
- the entire composite film therefore has a thickness of approximately 150 ⁇ m.
- a second film 2 is placed congruently on a first, rectangular film 1 at its end provided for the underside, and this second film 2 is folded over on a longitudinal fold line 3.
- a third film with the same dimensions of the first film 1 and congruent with this is placed on this arrangement.
- the surface areas 4, 5 of the three foils are then welded together.
- a container for moisture-crosslinking hotmelt adhesives according to the prior art consists of a filled film bag according to FIG. 3.
- a circular base film 6 is inserted into a tubular jacket 7, the lower edges of the tubular jacket 7 being folded inwards and with the base film 6 are welded.
- FIGS. 4 to 6 The particular advantages of the invention can be seen in FIGS. 4 to 6.
- two adhesive blocks 9, 10, freed from their foil bags are arranged one above the other on a grate 11, which simultaneously contains the heating rods or forms the heating rods.
- the whole facility is airtight and is under a protective gas atmosphere, e.g. B. nitrogen.
- the liquefied hot melt adhesive drips from the underside of the lower adhesive block 10 into the melting tank 12, from which it is conveyed to the application nozzles by means of a pump 13.
- the adhesive blocks 9, 10 correspond to one another in accordance with FIG. 5, a relatively large cavity 14 being formed due to the non-adapted lower and upper surface shape, in which a considerable proportion of outside air with the corresponding atmospheric humidity is contained.
- This outside air reaches the cavity 14 when the melting device is refilled and cannot be removed or can only be removed very poorly by protective gas purging, since the cavity 14 is relatively tightly sealed at its edges.
- the undersides of the adhesive blocks are matched to the tops, as can be seen in FIG. 6. Therefore, no or only a very small cavity 14 is formed, which can contain outside air with harmful air humidity.
