Definitions

  • the present invention relates to a packaging for two-component products with a basic container and a lid insert which can be inserted therein and which closes the basic container in an airtight manner and which comprises an upper and a lower push-in lid which, with their ripened edge surfaces, lie in such a non-detachable manner that the lids form a common cavity , wherein a seal is provided for contact with the ripened edge surface of the basic container in the edge surface of the lower press-in cover and a filling opening provided with a closure is arranged in the top of the upper press-in cover.
  • the base container serves, for example, to hold a component of a paint, while the additional component, for example a low-viscosity hardener, which is to be filled into the base container, is accommodated in the cover insert.
  • the additional component for example a low-viscosity hardener
  • a package of this type is known from DE-PS 34 07 783.
  • the lower and upper press-in covers are soldered together in the area of their wall surfaces.
  • the cover insert formed in this way is inserted into the basic container, the lower press-in cover is pressed into the basic container, so that the seal provided in the area of the edge surface of the lower cover also the ripened edge surface of the basic container comes into contact. In this way, the basic container is sealed airtight.
  • a pressure is applied to the ripened edge surfaces of the cover insert and the basic container with the aid of a securing element, for example a clamping ring, or by securing clips, so that the cover insert and basic container are connected to form a transport-safe packaging unit .
  • a securing element for example a clamping ring, or by securing clips
  • the filling opening of the lid insert provided with the closure is located adjacent to the edge on the upper side of the upper push-in lid.
  • the aim of this arrangement is to use the filling opening as a pouring opening after removing the corresponding closure, so that, for example, after removing the securing element (clamping ring), the lid insert can be removed from the basic container and the contents of the lid insert can be poured through the opening into the basic container .
  • the packaging described in DE-GM 73 04 262 also has a corresponding arrangement of the filling opening, ie here too the filling opening is simultaneously used as a pouring opening in order to be able to mix the component in the lid insert with the component in the basic container. Otherwise, the packaging described in this publication differs from the packaging described at the outset essentially only by the design of the side wall of the lid insert.
  • the invention has for its object to provide a packaging of the type specified, which allows a particularly tight fit of the lid insert closure with a particularly good possibility of emptying the lid insert.
  • This object is achieved in a package of the type described above in that the filler opening is arranged centrally, that a reinforcing bead arranged concentrically to the filler opening is provided on the top of the upper push-in lid in the edge region of the filler opening and that both the closure of the filler opening and the Bottom of the lid insert have such a thickness and consist of such a material that they can be pierced with a pointed object.
  • the solution according to the invention moves away from the idea of simultaneously using the filling opening of the lid insert as a pouring opening.
  • the filler opening is therefore no longer adjacent to the edge of the upper press-in cover, as is the case in the prior art, but in the middle thereof.
  • This has the essential advantage that the greatest possible distance between the filler opening or its closure and the edge of the upper press-in cover is achieved.
  • This has the effect that impact loads which act on the side wall of the lid insert do not directly affect the fill opening with a closure.
  • the inventor has thus found that, in the known packaging, the relatively narrow area of the upper side of the upper press-in cover between the edge of the press-in cover and the filler opening represents a weakened area.
  • both the closure of the filler opening and the bottom of the lid insert have such a thickness and consist of such a material that they can be pierced with a pointed object. This ensures that the contents of the lid insert can be emptied into the basic container in this way. In order to achieve such an emptying, the lid insert no longer needs to be removed from the basic container; rather, a pointed object, for example a screwdriver, is used first to pierce the closure of the filler opening and then flush the bottom of the lid insert so that the contents become clear can empty the lid insert into the basic container.
  • a pointed object for example a screwdriver
  • a reinforcing bead is provided there according to the invention.
  • This reinforcing bead is preferably roof-shaped and has a radially outer section with a relatively small inclination and a radially inner section with a strong inclination.
  • the reinforcing bead is expediently arranged at a certain distance from the edge of the filling opening, so that the closure for the filling opening with a projecting flange can rest against the annular surface of the upper side of the push-in cover, which is present radially inside the reinforcing bead. This allows the closure to be particularly tight.
  • the closure is preferably a press closure made of elastomeric material (for example polyethylene), which has the necessary elasticity to press fit onto the edge of the filling opening or onto the ring surface mentioned above. So that the closure can be press-fitted in the opening, the edge of the filling opening preferably has an approximately semicircular cut with an adjoining, radially recessed, depending flange.
  • the closure which is suitable for this purpose has an upper, essentially flat cover section and an annular flange which hangs from it, on the outside of which an annular recess for receiving the semicircular edge closure of the filling opening is arranged.
  • the closure When the closure is pressed into the opening, the radially further section of the ring flange of the closure located below the annular recess first passes the circular end and is thereby pressed elastically radially inwards. Upon further downward movement of the closure, the annular recess engages with the circular section in section, the part of the ring flange located below the annular recess springing outwards and coming into contact with the depending flange of the opening edge. In this way, the closure is securely held in the opening and can no longer be easily opened by hand.
  • its lid portion When the closure is firmly seated in the opening, its lid portion is positioned so that it does not hinder the stacking of another package, i.e. the top of the closure does not protrude beyond the edge of the top push-in lid, which provides support for the bottom of the next package.
  • the upper push-in cover has an outwardly curved side surface, which is rolled up so far on the lower edge surface that there is an approximately one and a half times the tube, and which has a gradation at the upper end with a contact surface for the rolled bottom fold of the basic container, the height and outer diameter of which are slightly smaller than the height and the inner diameter of the rolled on Bottom fold of the basic container.
  • the upper push-in lid has a side wall which is alternately formed by conical steps and cylindrical sections, the outer diameter of the uppermost cylindrical section being smaller than the inner diameter of the base of the base container.
  • Tinplate has proven to be a suitable material for forming the lid insert, preferably a hardness T 57.
  • the bottom of the lid insert has a thickness of 0.22-0.33, preferably 0.28 mm. Such a thickness enables piercing, while at the same time ensuring sufficient strength.
  • the remaining wall sections of the cover insert can have the same or a different thickness.
  • the closure is preferably made of polyethylene.
  • the packaging shown in Figure 1 for two-component products consists of a basic container 3 and a lid insert 6 inserted therein.
  • the lid insert is inserted into the basic container so that it is sealed airtight. It consists of an upper press-in cover 1 and a lower press-in cover 2, which are arranged opposite one another with their edge surfaces and form between them a cavity suitable for receiving one component of the two-component product.
  • the upper and lower press-in covers 1, 2 have essentially a bowl-like shape with a central, essentially flat middle part and a curved or conical edge part. At the conical edge part of the lower lid 2 is connected to the outside a substantially cylindrical edge part which, when the lid insert is pressed into the base container, bears against the inner surface of the base container shell under tension.
  • a sealing ring 11 which is arranged in the ripened edge area of the lower push-in lid 2, is pressed against the top of the ripened edge surface of the base container.
  • the edge surface of the lower lid 2 is formed by an approximately horizontally running ring flange which merges into the edge section that has matured, ie rolled towards the container axis.
  • a corresponding, horizontal ring flange of the upper cover 1 rests on this ring flange.
  • the two edge surfaces 4, 5 of the upper and lower covers are soldered to one another in the exemplary embodiment shown here.
  • the base container 3 is conical and has an approximately circular base surface 13.
  • the connection between the base surface and the container shell is formed by a rolled-up bottom fold 16, which is shown in detail in FIG. The container is thus only in contact with its base via the bottom fold 16.
  • the middle flat area of the upper push-in cover 1 merges radially outwards into a step 12 with a cylindrical shoulder and an annular bearing surface 15, to which an outwardly curved cover section 17 connects, which merges in the downward direction into a cylindrical section 14.
  • the cylindrical section 14 is adjoined by the edge surface 4 which is bent approximately at right angles and which comprises the aforementioned horizontal ring flange and a tubular rolled-up end section of the edge surface.
  • the end section rolled up in the form of a tube 10 is rolled up to the extent that there is an approximately one and a half times the tube, the end point of the curling being approximately opposite the contact point of the tube 10 with a clamping ring 9.
  • FIG. 2 the design of the individual edge areas, the lid and the basic container is shown in detail.
  • a clamping ring 9 is provided, the two legs of which point obliquely upwards and obliquely downwards are pressed against the tube 10 of the upper lid and the ripened edge region of the basic container when the clamping ring 9 is tensioned.
  • FIG. 2 also shows a further package which is stacked on the package described above.
  • the bottom fold 16 of the upper package rests on the annular receiving surface 15 of the upper cover of the lower package.
  • Between the base 13 of the The upper packaging and the top surface of the lower packaging remain an axial gap, while a radial gap is present between the bottom fold and the step 12.
  • the upper packaging is therefore only in contact with the lower packaging via the bottom fold 16 and the contact surface 15.
  • the lower press-in cover 2 is provided with a recess 7 in order to increase the volume of the cover insert.
  • the upper press-in cover 1 of the cover insert 6 is provided with a circular fill opening 18 in the middle of its upper side.
  • This circular opening 18 is used only for filling the corresponding product into the lid insert. It is designed in detail so that the edge of the filler opening 18 has an approximately semicircular closure 19 with an adjoining downward, radially recessed, depending ring flange 20.
  • the height of the reinforcing bead is less than that of the raised edge of the upper press-in cover 1.
  • the cover insert is further provided with a plastic press fastener 8 which has an upper, essentially flat cover section 22 and an annular flange 23 depending thereon.
  • the ring flange 23 is arranged directly on the edge of the flat cover section 22, so that the cover section protrudes somewhat radially outward from the ring flange and in inserted state of the closure comes to rest on the top of the edge closure 19 of the opening.
  • the hanging ring flange 23 of the closure 8 has on its outside an annular recess for receiving the semicircular edge end 19 of the filling opening 18.
  • Figure 1 shows the closure in the pressed state in the opening, in which the edge closure 19 engages in the annular recess of the flange 23.
  • the top of the closure 8 does not protrude beyond the raised edge of the upper push-in cover, so that the stackability of the packaging is not impaired by the closure.
  • the packaging is sold in the state shown in FIG. 1.
  • the arrangement of the closure in the middle of the lid insert and the formation of the reinforcing bead increase the strength of the packaging and, in particular, improve the security against the closure bursting out when the packaging is particularly exposed to lateral impact loads, as is the case during transport.
  • the user grasps a pointed object, for example a screwdriver, and pierces the closure first and then the bottom of the lid insert, so that the product in the lid insert can flow into the base container .
  • a pointed object for example a screwdriver
  • the base container is preferably conical or cylindrical.
  • the recess 7 of the cover insert is designed to match the required mixing ratio of the two components located in the base container and in the cover insert.
  • the closure and the bottom of the lid insert are pierced with a pointed object so that the component located in the lid insert can penetrate into the base container and mix with the component located in the base container.
  • air must be able to penetrate it, which is expediently achieved by repeatedly piercing the closure and the base.
  • this can also be accomplished in such a way that, after a single puncture, the tension lock that may be present is released and the lid insert in the basic container is tilted somewhat so that air can penetrate into the basic container in this way.
