Definitions
- the invention relates to a method for producing combi-packaging containers with supporting means for nesting a plurality of identical combination packaging containers, as described in claim 1.
- a method and a container produced by this method container has become known.
- a paper container consisting of container wall and container bottom is inserted into the thermoforming mold prior to thermoforming, the shape of which corresponds at least approximately to the outer shape of the combined packaging container to be produced.
- this prefabricated paper container is deformed during thermoforming of the existing plastic and molded from it part of the container inside, which firmly clings to the deep-drawing on the inner surface of the paper container and thereby connects with this.
- a stacking shoulder is formed in the region of the open end on the container wall. This is formed stepwise and circumferentially projecting outwards.
- the outwardly projecting stacking shoulder on the container accommodating this combination packaging container is supported on its upper opening edge.
- the disadvantage here is the formation of stacking aids and that the entire outer container, in particular the container bottom consists of a paper or cardboard material. Contact of the board material with moisture may cause damage or destruction of the cup.
- the plastic container is formed by deep drawing a plastic film of uniform thickness, wherein the plastic container is connected in the thermoforming mold with a layer of a different material, which, however, does not weld with the plastic material.
- This layer of the dissimilar material is formed in the form of a cuff, which is arranged before deep drawing in the deep-drawing mold so that its lower and upper edge is trapped during deep drawing of the plastic film. there the film can be drawn during deep drawing in the intended area for the contact with the sleeve to a minimum, the tightness of the container to be produced ensuring thickness.
- an outwardly projecting stacking shoulder is again provided in the region of its open end, which is supported in the region of the open end of the outwardly projecting opening edge of the other container.
- the wall section between the stacking shoulder and the opening edge is designed to be counter-conical with respect to the wall section extending toward the bottom so as to allow stacking.
- the disadvantage here is that the stability of the cup is reduced by the stacking shoulder and the compression of the associated deformation of the sleeve.
- the container wall is in turn formed gegenkonisch with respect to the other wall portion, whereby the support of the stacking shoulder is made possible on the flange-like protruding upper edge of the other cup.
- the formation of the stacking shoulder and the counter-conical wall section reduces the stability of the entire combination packaging container.
- WO 98/13270 A1 has disclosed another method for producing a cup-shaped combination packaging container, comprising a plastic inner part and an outer part, and a combination packaging container produced by the method.
- the cup-shaped inner part made of plastic and the shell-like outer part surrounding the outer plastic part are produced separately from one another.
- the jacket-like outer part is pushed over the finished molded, cup-shaped plastic inner part and then on the cup-shaped Plastic inner part fixed.
- latching means are provided on the plastic inner part, in which the shell-like outer part releasably engages for fixing on the cup-shaped plastic inner part.
- a first latching means in the bottom region of the cup-shaped plastic inner part is formed by a circumferential shoulder arranged there, the outer diameter of which is greater than the inner diameter of the lower edge of the shell-like outer part.
- Another latching means is formed by the upper outwardly projecting edge of the cup-shaped plastic inner part.
- the coat-like outer part is pushed when pushing over with its upper edge so far in the direction of the peripheral edge until it abuts it and is held by the engagement between the edge and the circumferential shoulder.
- the present invention has for its object to provide a method for producing combination packaging containers, in which the inner container is deformed inline in the shell-shaped outer part during its manufacture in and stacking means are formed in undeformed presentation surface of the outer part.
- the overall strength of the cup while saving raw material for the production of the inner container should be increased.
- an approach according to the features specified in claim 2 is advantageous because it is achieved depending on the wall thickness of the outer part by appropriate arrangement of or the inner wall parts for the subsequent molding process without additional aids the formation of stacking aids or stacking means.
- the one or more inner wall parts not only form a stiffening and reinforcement of cuff-shaped outer part, but also simultaneously forming projections or extensions for forming the stacking means.
- an approach according to the features specified in claim 8 is advantageous because it can be transmitted from the open end on the flange and the shell-shaped outer part, the stacking forces on the footprint. This makes it possible, further, to reduce the wall thickness of the inner container to a minimum, and this can extend to the film thickness. It is only to consider a sufficient tightness of the recording room.
- stacking means can be provided, which are formed by the inner container itself or in cooperation with shaping elements of the jacket-shaped outer part thereto.
- edge section with the wall part arranged thereon on the inside of the outer part a circulating stacking shoulder is thus easily formed on the inside of the combination packaging container facing the receiving space.
- Another defined support means forms the transition region from the bottom into the container shell, which can be produced by exact shaping in the deep drawing mold itself.
- a procedure according to the features indicated in claim 14 is advantageous because thereby the stack height of stacked combi - packaging containers can be kept low and still a mutual radial jamming of the same is prevented.
- thermoforming mold predetermined stacking means or stacking aids are formed, but at the same time the Anformung can be performed on the outer part in one operation. Due to the predefined In turn, indentations enable a precise stacking of identical combined packaging containers and prevent a mutual radial jamming. As a result of the fact that the lower edge section of the outer part, which faces the floor, is distanced from the floor, easier demoulding of the combination packaging container can be achieved. In addition, here with open cut edges, the Aus GmbH can be found because a contact with the footprint is avoided.

If a corresponding displacement or displacement of the recesses 25, 25 'in the circumferential direction against each other, the bottom 9 projects with its indicated in dashed lines corner 30 and 30' in the radial direction on the here in the parallel direction with respect to the longitudinal axis 13 aligned wall portion 26th of the dent 25. This is an independent of the mant egg-shaped outer part 4 support the two inter-stacked inner container 3, 3 'together.
- the jacket-shaped outer part 4 with an additional wall part 19 in the region of its edge section 34 facing the contact surface 15 on its inner side 7, this being provided either by an envelope or crimping or else by a separate component can be formed.
- the wall portion 19 with its end facing the open end 10 32 extend to the stacking shoulder 20 zoom.
- jacket-shaped outer part 4 seen in the direction of the longitudinal axis 13, does not extend completely over the entire longitudinal extension or height of the combined packaging container 2, a visible edge of the inner container 3 remains between the base 9 and the end face 35 of the outer part 4. Due to the rectilinear design of the outer part 4 seen in axial section, disturbing edges or interruptions are also avoided in the region of the outer side, which in turn completely preserves a presentation surface which is important for marketing.
- the secure stacking of several identical combination packaging containers 2, 2 takes place at the stacking shoulders 20 or the stacking cam with the bottom 9, whereby here also unique support conditions are created solely by the components of the inner container 3.
- the section 22 of the combination packaging container 2 between the contact surface 15 zuwendbaren end portion 16 and the support surface 21 in turn serves to form the support means 14, in which case the lower end face 35, which is the bottom 9 facing, seen in the direction of the longitudinal axis 13 within this Section 22 is arranged.
- the end face 35 is arranged in the direction of the longitudinal axis 13 approximately at half the longitudinal extent or half the height of the indentation 25. The further the end face 35 is arranged at a distance from the bottom 9 in the direction of the stacking shoulder 20, the greater the uncovered area of the inner container 3.
- the portion of the inner container 3 between its bottom 9 and the end face 35 of the outer part 4 similar, as has already been described previously in FIG. 9.
- This in turn forms a shoulder 31, which merges into the bottom 9 via the shoulder wall 33 and the corner region 33.
- the shoulder wall 33 with respect to the longitudinal axis 13 may have the same inclination with respect to the container wall 8 or else be aligned cylindrically up to a counter-conical inclination.
