Definitions

  • the present invention relates to the field of packaging. It relates to a method for producing a cup-shaped combination packaging container, which comprises an inner cup-shaped, downwardly tapering plastic inner part and the plastic inner part outside surrounding, fitting, coat-like outer part.
  • Combination packaging containers of the type mentioned are from earlier patents of the applicant, the EP-B1-0 102 522 or the EP-B1-0 408 515 , known.
  • Stackable combination packaging containers in which a cup-shaped, usually deep-drawn from a plastic inner plastic part of an outer part of a different material, eg
  • Paper, cardboard or any other plastic that has been encased has several advantages.
  • the container can be optimally adapted to the respective application by using two different materials.
  • an outer part made of a material which has a thermally insulating effect.
  • the use of a separate outer part has the advantage that the outer part can be printed separately from the container with pictures, text, advertising, instructions or the like., Which allows a much better print quality.
  • the separation of the container into individual fractions provides significant advantages in terms of waste disposal (recycling).
  • the coat-like, usually printed outer part is first produced.
  • a jacket made of cardboard material we wound a corresponding blank around a mandrel and glued the side edges overlapping each other.
  • the outer part is then inserted into the thermoforming mold of a plastic thermoforming device.
  • the plastic inner part is deep-drawn into the outer part, as in the already mentioned EP-B1-0 102 522 is described.
  • the deep-drawn plastic inner part connects in this way form-fitting with the outer part to the finished combined packaging container.
  • Suitable additional embodiments of the outer part such as a Umfalzung the lower edge (12 in Fig.
  • Another major disadvantage of the known method lies in the complexity of the machines used. Instead of a simple deep-drawing device in which the cup-shaped container is made by deep drawing from a film, specially prepared, expensive and complicated machine sets are required for the known method, which in a first station of printed blanks the outer parts Forming and bonding, the finished exterior parts via a transfer station fit accurately into the special thermoforming molds of a special thermoforming device, and the deep drawing device finally the plastic inner parts into the outer parts deep draws.
  • the container usually has - as in Fig. 1 of the EP-B1-0 408 515 it can be seen - to improve the stackability a serving as a support shoulder, circumferential shoulder (3 in Fig. 1 of the EP-B1-0 408 515 ).
  • the paragraph is due to the manufacturing process equally present in the outer part and in the molded plastic inner part. Due to the heel, despite the inherently stiffening composite structure of the container, there is a weakening of the container wall with respect to axial compression forces, that is to say perpendicular to the container bottom, because the container wall tends to buckle in the region of the shoulder. Such weakening of the container against axial compression forces is especially undesirable if the filled and sealed containers are to be stacked on a pallet or the like directly in several layers.
  • the object of the present invention is to provide a method for producing a combination of plastic inner part and mantelartigem outer part combination packaging container, which avoids the aforementioned disadvantages and a simplification of the production devices, reducing the transport and storage costs for the finished Container, and an improved rigidity of the container in the axial direction allows.
  • the object is solved by the entirety of the features of claim 1.
  • the essence of the invention consists in producing or molding the outer part and the inner plastic part separately and then connecting the two parts together by sliding the outer part over the inner part and fixing it on the inner part.
  • thermoforming devices it is possible with simple thermoforming devices to produce non-specific, cup-shaped plastic inner parts, which are then connected as needed with the correspondingly printed or otherwise assembled outer parts for the finished combination container.
  • the flexibility in manufacturing is increased and storage and transport significantly simplified.
  • the possibility arises that the plastic inner parts are produced directly at the bottler of the containers on simplified machines in-line and then connected to the specific outer parts in stock.
  • a cup-shaped plastic inner part which comprises latching means, in which the shell-like outer part releasably engages for fixing to the cup-shaped plastic inner part.
  • the method according to the invention is further distinguished by the fact that the latching means comprise a circumferential shoulder arranged in the bottom area of the cup-shaped plastic inner part, the outer diameter of which is greater than the inner diameter of the lower edge of the jacket-like outer part such that the jacket-like outer part pushes over the cup-shaped plastic inner part with its lower edge is pushed so far over the circumferential shoulder that it snaps behind the shoulder, that the latching means further comprise an upper, outwardly projecting edge of the cup-shaped plastic inner part, and that the shell-like outer part when DrREMschieben over the cup-shaped plastic inner part with its upper edge from below to the Edge abuts and is held after locking between the edge and the circumferential shoulder.
  • the jacket-like outer part can absorb any unwanted axial compression forces applied to the container without weakening.
  • the coat-like outer part can be produced in different ways.
  • a blank is wound into a jacket to produce the jacket-like outer part, and the side edges in an overlapping area are glued together.
  • the outer part can be pushed in this way without further action on the plastic inner part.
  • a blank is folded along two fold lines for the production of the jacket-like outer part, and the side edges are folded in glued together an overlap area.
  • the bonded outer part is then in a flattened form. It can be stacked, transported and stored in an easy and space-saving way. If necessary, the flattened outer parts are then stretched tubular and pushed over the plastic inner part.
  • the plastic inner part is characterized in that it is cup-shaped and tapered downwards, and that latching means are provided on the plastic inner part, in which the shell-like outer part can releasably engage for fixing to the cup-shaped plastic inner part.
  • the latching means comprise a arranged in the bottom region of the plastic inner part circumferential shoulder, the outer diameter is greater than the diameter of the lower edge of the jacket-like outer part, and that the latching means further comprises an upper, outwardly projecting edge of the cup-shaped plastic inner part, in particular in the form of a sealing flange, comprise against which edge the shell-like outer part pushes when pushing over the cup-shaped plastic inner part with its upper edge.
  • a circumferential, inwardly projecting shoulder is provided.
  • the circumferential paragraph forms the upper boundary of a circumferential trailing, which is bounded at the bottom by the encircling shoulder.
  • the initiation of compression forces in the coat-like outer part is facilitated by the rear pull.
  • Fig. 1 shows in a partially sectioned view of a plastic inner part, as it is suitable for the inventive method.
  • the half of the figure to the left of the dot-dashed center line shows the longitudinal section, the right half of the figure an uncut side view.
  • the cup-shaped plastic inner part 1 is simply conical in the reproduced example with a 9 tapering towards the bottom diameter. It is expressly understood that the simple conical cup represents only one embodiment, and that within the scope of the invention, of course, other stackable shapes such as four-, six- or otherwise polygonal or mixed ecki grounde forms are conceivable.
  • the conical wall 2 of the cup-shaped plastic inner part 1 is limited in the example shown at the top by a sealing flange 3, by means of which the cup can be closed. This can be done for example by sealing with an aluminum foil. But there are also other edge shapes conceivable, as for example in the left half of Fig. 1 from the EP-B1-0 102 522 are reproduced.
  • the wall 2 of the cup starting from the upper edge or sealing flange 3, down through into the bottom area without a shoulder continuously formed. Only immediately in the bottom area a circumferential pull 5 is provided, the top by an inwardly projecting, circumferential paragraph. 4 is limited, whose function later related to Fig. 4 and 5 will be explained in more detail.
  • the rear train 5 is bounded by an outwardly projecting, circumferential shoulder 8, which merges directly into the bottom 9 and forms an annular bead.
  • the pull 5 itself is divided into two pull-back portions 6 and 7, of which the upper pull-back portion 6 is substantially cylindrical, and the lower pull-back portion 7 is slightly opening to the floor.
  • paragraph 4 provides a support shoulder which allows the defined nesting of the cups.
  • a "spring base” is realized with the pull 5, i. the bottom 9 can move resiliently in the axial direction when axial pressure forces occur. This property is important for the stiffness of the combination container, which will be discussed in more detail below.
  • the geometry of the rear pull allows the plastic inner part 1 to be deep-drawn even without the use of complicated sliding molds when a plastic material with increased shrinkage behavior, such as, for example, is used.
  • Polypropylene (PP) is used because the thermoformed cup despite the back pull 5 due to the shrinkage can easily remove from a solid thermoforming mold.
  • the bottom 9 of the plastic inner part 1 can be designed differently. Regarding the possibilities here on the EP-B1-0 102 522 directed.
  • the bottom 9 has an outer footprint 11 which annularly surrounds a central retracted bottom portion 10.
  • a plastic inner part 1 of in Fig. 1 illustrated type produced by deep drawing from a plastic film or other suitable manufacturing process.
  • the finished cup is then then with a coat-like outer part 12, as exemplified in Fig. 2 is reproduced connected to a combination packaging container by the outer part 12 is pushed like a cuff from below over the cup-shaped plastic inner part 1 and fixed to the inner part.
  • This has the particular advantage that only those adapted to the product to be packaged, product-specific printed exterior parts that fold easily and store space, must be kept in stock, while the (unspecific) plastic inner parts as needed directly at the bottler or on be made elsewhere on simple thermoforming devices and then combined with the outer part.
  • the shell-like outer part 12 may be made of different materials and manufactured in different ways. Regarding the possibilities be on the EP-B1-0 102 522 and the EP-B1-0 408 515 directed. If the outer part 12-which is frequently the case-is produced from a blank from outside and / or inside printed cardboard material, then the blank is wound like a jacket on a mandrel and then the side edges are glued together in an overlapping area 13. Of course, the outer part 12 for better separation of plastic inner part 1 and a predetermined separation strip with handle rafters and corresponding perforation lines are provided, as shown in the EP-B1-0 408 515 is described.
  • the fixation of the jacket-like outer part 12 on the cup-shaped plastic inner part 1 is preferably carried out by a releasable latching.
  • the outer edge of the shoulder 8 is (slightly) larger than the inner diameter of the lower edge 15.
  • the height of the outer part 12 in the axial Direction is slightly less than the (axial) distance between the bottom of the sealing flange 3 and the shoulder eighth
  • the coat-like outer part 12 is according to Fig. 2 far beyond the plastic inner part 1 according Fig. 1 pushed until it abuts with the upper edge 14 on the underside of the sealing flange 3.
  • the lower edge 15 of the outer part 12 slides over the shoulder 8, which yields resiliently due to material and geometry and reduces its outer diameter.
  • the lower edge 15 has slipped over the shoulder 8 and has released it again, so that the shoulder 8 springs back into its starting position latching.
  • the shell-like outer part 12 is so releasably fixed between the sealing flange 3 and the shoulder 8 on the plastic inner part 1.
  • the upper edge 14 is covered by the sealing flange 3 and the lower edge 15 by the shoulder 8 protective.
  • This is advantageous if, for example, a coat-like outer part 12 of moisture-sensitive cardboard material is to be used. It is also possible to provide a Umfalzung to protect the edges, as shown in the EP-B1-0 102 522 is known.
  • a more or less tight fit of the outer part 12 can be achieved on the inner part.
  • the outer part 12 has a largely smooth outer surface without debilitating paragraphs or the like. On. For this reason, the outer part 12 is able to absorb relatively large axial compressive forces. Accordingly, the outer part 12 in the finished combined packaging container 16 can absorb axial compressive forces acting on the bottom 9 and the sealing flange 3 of the plastic inner part. An essential role is played by the above-mentioned "spring floor". If axial pressure is applied to the plastic inner part 1 of the combination packaging container 16, the bottom 9 shifts resiliently in the direction of the sealing flange 3 until the shoulder 8 presses against the lower edge 15 of the jacket-shaped outer part 12.
  • the stack height ie the increase in height by the nesting of two containers 16, 16 'depends significantly on the height of the rear train 5 from. If the height of the rear pull 5 and thus also the stack height is increased, the inner diameter increases on the shoulder 4, 4 '. This makes it possible to increase the outer diameter of the shoulder 8, 8 '.
  • the shoulder 8, 8 'then protrudes beyond the lower edge 15 of the latched outer part 12, 12', whereby latching function and protection of the lower edge 15 can be improved.
