Definitions

  • the invention initially relates to an article produced by the two-component injection method.
  • Such articles are known and find use, for example, in the field of food packaging or storage containers or lids thereof, such as for cosmetics and / or pharmaceutical products. These consist of two plastic components, which can be injected to form the object at the same time. However, objects are also known in which first a component is injected into the mold and then overmolded by the second component. The two components can be designed differently with regard to their color. There are also known articles in which two components made of different plastics were used.
  • an insert is arranged in the separating surface between the components.
  • the separating surface is in this case the plane between the two plastic components, in which these components merge in the course of simultaneous or successive injection.
  • an insert is arranged according to the invention. This may be superimposed on this after injection of the half part made of a first component to hereafter to be over-injected together with the half-part from the second component.
  • the insert is then trapped captive between the two plastic components.
  • the insert at least in one embodiment, in which the two components each span the insert over the entire surface, is protected from external loads. For example, a manipulation of the insert or an exchange of the same is not destructive feasible.
  • the insert part can be arranged on the upper side of the first component facing the second component, ie in the region of the later parting surface.
  • the insert may also be positioned on the underside of the first component, facing the further component to be back-injected in the area of the separating surface.
  • the insert is a label.
  • This may include information about the object or about a stored in the example designed as a vessel object medium or the like.
  • this may be a product advertising label.
  • Such a label is preferably back-injected in the manner of an in-mold label, at least from a first component, after which the second component is injected via the first component and the in-mold label.
  • the insert may be a sticker, which is set after spraying the first component to form a half part by means of the self-adhesive layer on this, for final overmolding with the second component.
  • optical or decorative advantages brings a development in which the insert is a rigid part, so on, for example, a metal part, such as a coin or the like.
  • a rigid insert acts especially in a curved separation surface rather settling off this separation surface three-dimensional.
  • a rigid part in cooperation with a plane separating surface acts in a rigid part as in particular a coin whose measured perpendicular to the interface plane thickness.
  • the rigid part may be arranged touching the separating surface in a tangential manner in front of the same viewing direction and tangentially touching the separating surface behind the separating surface. Further alternatively, the rigid part can also cut the separation surface secant.
  • the insert may also be an electrical functional film, for example in the form of a transponder or other contactless ID systems, such as, for example, smart labels or the like. Such functional films are used, for example, for theft protection and / or identification in the course of a scan in the checkout area at sales objects.
  • the proposed embedding of the insert between the components proves to be particularly advantageous since this counteracts manipulation.
  • the insert is at least partially not covered by at least one of the layers. Accordingly, a window-like opening area may be provided in the covering area to the insert.
  • This window-like opening region can be formed both in the region of the article section produced by the first component and in the region of the article section produced by the second component.
  • both halves can have such a window-like opening in projection onto the enclosed insert.
  • the invention relates to an article according to the features of the preamble of claim 1.
  • one of the layers in the dividing plane is printed.
  • a half-piece made of a first component can be fed to a printing device which applies pressure to the surface to be over-injected or later formed on the parting line, for example in the form of a logo and / or in the form of lettering.
  • the invention relates to an article according to the features of the preamble of claim 1, wherein it is proposed to solve the problem that one of the layers in the region of the parting plane has an engraving-like shape. By this engraving recessed and raised areas are cleared on the surface facing the other component, which achieve a pleasing visual effect in particular by shadow effect.
  • At least one of the layers is kept transparent.
  • This at least one layer is preferably the outer layer, which thus releases the view of the embedded insert.
  • both layers can also be kept transparent, for example in the case of a drinking vessel or the like produced according to the invention.
  • the various component layers can also be kept differently colored in color.
  • the invention also relates to a method for producing an article in the multi-component injection method.
  • a component is injected, then treated the provided for overmolding with the second component separating surface in the sense is that a part is placed or glued or an engraving or printing is made and that then this thus treated release surface is at least partially overmolded with the second component.
  • a method is specified, by means of which a manufactured in the multi-component injection process object can be produced, which has an insert in the parting plane between the components or in which one of the layers is printed in the parting plane or is provided with an engraving , In this method, different components can be used in terms of color, starting material and / or transparency.
  • FIG. 1 is a perspective view of an article according to the invention in an exemplary embodiment
  • FIG. 2 shows the section along the line H-II in Fig. 1.
  • FIG. 3 shows the section along the line III-III in Fig. 2.
  • FIG. 4 is a sectional view corresponding to FIG. 2, but relating to an alternative embodiment
  • FIG. 5 shows a further embodiment of a representation according to the sectional view in Fig. 2.
  • FIG. 6 shows the section along the line VI-VI in Fig. 5.
  • Fig. 7 is a sectional view corresponding to Fig. 6, but concerning a further embodiment.
  • the socket 1 has two component layers 2 and 3, wherein a first component layer 2 forms the inner side layer on the can side and the component layer 3 forms the substantially comprehensive, the first component layer 2 comprehensive, substantially visible position.
  • the second layer 3 facing surface 4 of the first layer 2 forms together with the first layer 2 facing surface 5 of the second layer 3, a separation surface 6 between the layers 2 and 3, in which formed by this separation surface 6 parting the components of the layers. 2 and 3 are fused together.
  • an insert 7 is arranged according to the illustrations in FIGS.
  • the latter is in the illustrated embodiment, a label 8 in the form of an in-mold label, which label 8 is injected behind in the injection mold by the component for the first layer 2.
  • this insert 7 may also be a sticker which is applied to the already sprayed first layer 2, on the surface 4.
  • the insert 7 is overmolded by means of the component for the second layer 3 and thus completely according to this embodiment, both front and back sides integrated over the entire surface in the article 1.
  • the second layer 3 is kept transparent. Consequently, the view is free on the integrated insert 7, which represents a logo, for example.
  • the insert 7 may be a functional part, so on, for example, a functional film in the form of a transponder or the like. It proves to be advantageous if, as preferred, the first layer 2, the second layer 3 is not kept transparent.
  • the surface 4 of the first layer 2 may be provided with an engraving.
  • the component of the second layer 3 dips into the recesses worked out in this way.
