Definitions

  • the invention relates to a packaging container, in particular a packaging tube for pasty packaging materials with a tamper-evident characteristic according to the preamble of claim 1.
  • Plastic packaging tubes have largely prevailed alongside metal tubes for the packaging, application and delivery of technical, cosmetic and pharmaceutical pasty packaging materials. Because of their diffusion resistance, metal tubes were superior to plastic tubes for packaging oxidation-sensitive packaging materials. With the development of new plastics and laminates, for example for the production of tubes for tube tube production, either by extrusion or so-called longitudinal seam welding, the superiority of the metal tube was largely eliminated, so that metal and plastic tubes as a deformable packaging for example, oxidation-sensitive packaging considered equivalent are. For the development of new plastics and laminates (tube materials), the highly developed, error-free tubes guaranteeing manufacturing technology for plastic tubes is added.
  • Tube materials and manufacturing technology result in deformable tubes, with which a consistent quality of the packaging material from filling to emptying of the tubes is guaranteed, the tube is in addition to their function as packaging continue to be an advertising medium, the advertising shown there packaging material identification and other information relevant to the origin can enclose.
  • the advertising on the tubes next to the name of the product is creatively originated, ie producer-specific, so that consumers decide on the basis of optical identification which product they are buying from which manufacturer, in the expectation of acquiring the same product of the same quality , With this expectation, this optical identification is superficial, which leads to problems for the packaging material manufacturer and / or packer in terms of its guarantee of origin, quality and quality consistency against imitators.
  • Imitators can equip, for example, packaging tubes almost true to the original, under equipping here is a reproduction of a special tube shape with the same original printing understood, these replicas usually have tubes and contents, ie packaging materials, other quality than the original manufacturer. If replicas are identifiable by the consumer in terms of perceived loss of quality in terms of tubes and / or packaging material, consumers expect these copies to have been copied to the original manufacturer, a circumstance which leads to problems for the latter in terms of origin, quality and guarantee of his products ,
  • the prefabricated head technique relies on the connection of a prefabricated tube head with a tube tube, in that, as a type of connection, the tube is melted by applying heat and pressure to the head, while the other type is connected to the head and tube by an injection molding process.
  • the tube tube is connected to a tube head during its molding in a die, wherein the shaping can be done by forming a plasticized material portion or by injection molding.
  • a method that connects the connection of prefabricated tube heads with plasticized, to be pressed material portions for the production of tubes. The developments of these manufacturing processes pursue two objectives, namely of a technical and aesthetic nature.
  • the aim of the art is, on the one hand, the production of dense and mechanically strong connections, which, on the other hand, must be visually inconspicuous.
  • the invention breaks with the above-outlined notion of those skilled in the art by maintaining the mechanical qualities of a head-to-tube seam, but making the join or parts thereof visible.
  • the head carries a marking of other colors.
  • the label is as one on the shoulder of the head formed circumferential ring, which is visible during the connection between the tube and head by pressing an annular portion of plasticized plastic other colors than the shoulder of the head and optionally the tube on the shoulder visible.
  • a method for the production of tubes with the above-indicated marking, in which a prefabricated head with a tube by means of an annular portion plasticized plastic, preferably round or lenticular cross-section in which the portion along the inner periphery of an upstanding edge portion of the pipe and between or partially placed on the outer circumference of the shoulder of the head and pressed by applying the rising edge portion in the direction of a spout of the tube head by means of a mandrel and a die.
  • the annular marking closes immediately, ie to the front edge of the edge portion, so that the ring is spaced by the length of the edge portion of the deflection.
  • Fig. 1 shows the head end of a packaging tube 10, hereafter called tube 10 for short.
  • the tube 10 is formed from a tube tube 11, called tube 11 below, formed with a tube head 12, also referred to as head 12, with applied closure 13 is engaged.
  • the head 12 comprises a shoulder 14 and a spout 16 (FIG. Fig. 2 ).
  • the tube 11 is made of a plastic monofilm, plastic film laminates or a plastic metal foil laminate, on its outer visible surface facing away from the tube interior, ie on its outer visible surface which are welded in strip form to a tube 11 bent along the longitudinal edges of the strips. Tubes 11 may also be extruded, in this case eliminating the longitudinal seam welding.
  • the tubes 11 are engaged at one of their open ends with prefabricated heads 12.
  • the heads 12 are made by injection molding of the tube production separately made of plastic.
  • the head 12 includes a disk-shaped shoulder 14 with projecting from the shoulder 14 spout 16 which can be opened and closed by means of the shutter 13.
  • the outer diameter of the shoulder 14 of the head 12 is slightly smaller than the inner diameter of the tube 11, so dimensioned that the material used for the connection during the compression molding, the peripheral edge of the shoulder 14 while filling an annular gap between the peripheral edge of the shoulder 14 and the inner surface of the tube 11 can flow around.
  • a material portion 17 of plasticized plastic which is to be chosen so that it with the application of pressure and optionally heat with the plastic of the head 10 and the plastic of the tube 11, in the case of a laminate with the inner layer of the tube 11 connects.
  • Fig. 2 shows schematically shown as part of a pressing tool a round mandrel 20, on the axially extending peripheral surface of a tube tube 11 is pushed.
  • the upper free end of the mandrel 20 is designed (contoured) so that the tube head 12 rests on it completely with its inner surface.
  • the tube head 12 is formed by the disk-shaped shoulder 14, from which the hollow cylindrical spout 16 engages, in which the mandrel 20 centric, projecting spinous process 21 engages, so that the tube head 12 is held exactly centered on the contoured free end of the mandrel 20.
  • Fig. 2 projects in the axial direction of the mandrel 20, an annular portion 22 of the tube tube 11 the transition 23 of the mandrel bevel 24 to the outer periphery 25 of the mandrel 20, the end face.
  • the axial extent of the annular portion 22 depends, see Fig. 4 , According to the distance A, with the free circumferential edge 26 of the section 22 - seen from the center line of the head 12 - to support and thus an outer peripheral delimitation 27 of the label 15 forming to rest.
  • the head 11 according to Fig. 2 has on its outer surface a step 29, which rotates around the outer circumference of the shoulder 14 and the spout 16 upstanding surface 30 forms the inner circumferential boundary 28.
  • the transition 23 of the mandrel bevel 24 may be expedient to provide the transition 23 of the mandrel bevel 24 to the outer circumference 25 of the mandrel 20, the mandrel 20 circumferentially with a multi-chamber gradation 31.
  • the Mehrcrostufung 31 (hereinafter also abbreviated as grading 31) comprises two chambers 32, 33, the first chamber 32, starting from the outer periphery of the mandrel 20 in the form of a slope in the direction of the center line M, starting in the second chamber 33, which in turn opens into the mandrel slope 24.
  • the diameter of the opening closest to the center line M that is to say the circumference of the second chamber 33, is dimensioned such that it is covered by the outer circumference of the shoulder 14 of the head 12, so that the chamber 33 engages with the tube head 12 applied to the mandrel 10 the shoulder 14 forms an undercut 34 formed in the end face, while in the axial direction the first chamber 32 is in communication with the inner peripheral surface of the portion 22 of FIG Pipe 11 and the outer periphery of the shoulder 14 of the tube head 12 an open to the shoulder 14, axially to the mandrel 20 extending annular space 35 forms.
  • Fig. 4 shows a relation to a parallel to the center line of a tube head 12 extending peripheral surface (not shown), as a slope 36 formed to the center line peripheral surface.
  • the Fig. 2, 3 and 4 show various deformable connections between tube tube 11 and head 12.
  • the compound according to Fig. 2 meets normal requirements for a connection, while the after Fig. 4 higher claims than the connection after Fig. 2 is sufficient, this because the slope 36 a larger one-sided connection surface than the parallel surface after Fig. 2 represents.
  • the connection is after Fig. 3 designed to include in the connection, by the undercut 34, the inner surface (to the tube interior facing surface) of the head 12 as an addition to the surfaces of the annular space 35.
  • step 29 on the outer surface of the shoulder 14 of the head 12 can also with the heads 12 after the 3 and 4 be provided.
  • material portion 17 as a ring, equally preferred circular, lenticular or teardrop-shaped cross section expediently rests on the inner surface of the annular portion 22 annular spaces 35 overlapping.
  • FIGS. 5 and 6 show the means for connecting the tube tube 11 with the head 12.
  • 39 is in Fig. 5 denotes an annular die, into which a mandrel 20 with applied tube 11, head 12 and material portion 17 is retracted, before the beginning of the pressing process, the completion in Fig. 6 is shown.
  • the die 39 (shown only schematically) can be a preferably spring biased in the direction of movement of the mandrel 20 inner ring 40 which serves as hold-down of the head 12 on the mandrel 20 and with its outer diameter as an axially movable shaping wall and resting on the shoulder 14, for example a inner circumferential boundary 28 forms.
  • the shaping contour of the die 39 is formed from a cylindrical portion 41 and a radiused portion 42.
  • the inner diameter of the cylindrical portion 41 corresponds to the outer diameter of the mandrel 20 with pushed-tube 11.
  • the radius-shaped portion 42 is dimensioned so that it forms a rear part of the annular portion 22 as a radius-shaped transition from tube 11 to head 12, while the front part in Engagement with the outer surface of the shoulder 14 is brought during the pressing process.
  • the method of joining a prefabricated head 12 to a pipe 11 to form the annular joint on the shoulder 14 of the head 12 essentially proceeds in six substeps.
  • the first step consists of loading the Mandrel 20 with a tube tube 11, in such a way that an annular portion 22 of the tube 11 projects beyond the transition 23 of the mandrel bevel 24 to the outer periphery 25 of the mandrel 20.
  • the axial length of the section 22 is measured according to which radial distance the free circumferential edge 26 of the section 22, forming the outer peripheral boundary 27, should have after the compression.
  • the position of the outer peripheral delimitation 27 increases in the direction of the spout 16, while the delineation in the direction of the transition 23, ie in the direction of the outer circumference of the mandrel bevel 24 decreases during its shortening.
  • the prefabricated head 12 is cleared up onto the mandrel 20, the latter being held centrally on the mandrel 20 via the opening of the spout 16 and spinous process 21 and being circulated by the annular section 22.
  • the material portion 17 of connecting material is applied to the side of the shoulder 14 facing away from the mandrel bevel 24, ie the visible outer side of the shoulder 14.
  • the material portion 17 rests against the inner circumference of the portion 22 and completely rotates on the latter.
  • the material portion 17 consists of a plasticized plastic, which is to be chosen in its composition so that it is using pressure and possibly heat with the plastic of the head 12 and the tube 11, in the case of a Lamites with the inner plastic layer of the tube 11 connects.
  • the material portion can be prefabricated and inserted or applied by extrusion on the shoulder 14, preferably annular spaces 35 overlapping.
  • the plastic of the material portion 17 has a color that differs clearly visible from the color of the plastic of the prefabricated head 12 and optionally the color of the tube 11.
  • a mandrel 20 loaded with tube tube 11, tube head 12 and a material portion 17 moves in a fourth increment in the open annular die 39 a. If an inner ring 40 is provided, the outer surface of the shoulder 14 engages the inner ring 40 and pushes it back during the retraction movement of the mandrel 20 into the die 39 against its spring bias in the die. The compression and formation of the marking 15 takes place during the fifth method step.
  • a portion of the material portion 17 is fluidly displaced by the annular portion 22 in the direction of the spout 16 until the over the shoulder surface displaced plastic, for example, runs up to the rising surface 30 of the step 29 or on the outer circumference of the inner ring 40 .
  • the connection of tube 11 and head 12 is carried out, the annular portion 22 is by means of displaced in the direction of the spout 16 plastic material portion 17 with connected to the shoulder 14 and there is an annular marking 15 on the surface of the shoulder 14, the spout 16 spaced circumferentially formed, which is delimited by an inner 28 and outer circumferential delimitation 27.
  • Means (rising surface 30, inner ring 40) for forming the inner circumferential boundary 28 are preferred for the precise representation of the marking 15, but it is also possible, before the free-rotating edge 26 of the section 22 in the direction of the spout displaced plastic on the free Leak off shoulder 14.
  • the mandrel 20 is extended with packaging tube 10 from the die 39 and the tube 10 is deducted from the mandrel 20, after which the manufacturing process, ie the process for producing a tube 10 with marking 15 is repeated.
