Definitions

  • the invention relates to a plastic closure according to the preamble of claim 1.
  • Plastic closures are known for a wide variety of applications, e.g. for packaging food or chemicals. All plastic closures consist of at least one part with a lid function and a base part which is connected to the container and is in positive engagement with the lid part in the closed state. Depending on whether the lid is screwed or folded, the Kuriststoffrfound is made of one or more parts.
  • closures with a round basic shape there are essentially closures with a round basic shape and closures with a rectangular basic shape.
  • the closures with a round basic shape can be found as a twist-off or hinged closure, particularly on bottles or canister-like containers, or as a twist-off closure also on the known rectangular containers for milk, juices, etc.
  • Closures with a round basic shape, in particular as a twist-off closure always have a not inconsiderable height on and are therefore, for example unsuitable for the above-mentioned cuboid containers, since this reduces their stackability.
  • Seals with a rectangular base are therefore normally used, in particular for rectangular containers. These are generally designed as a snap or snap lock and can be used on them Be kept very flat, so that the cuboid containers are still practically unlimited stackable.
  • An additional component of a plastic closure which is particularly important for the packaging of food, is the so-called guarantee seal, which is broken when the closure is opened for the first time and thus serves as a sign for the consumer whether the closure has already been opened.
  • guarantee seals can take many different forms. In the case of twist locks, there is often a ring around the base part, which is connected to the lid until the first opening. Another possibility is to place the guarantee seal in the central opening of the closure and to provide it with a handle so that the guarantee seal can be removed by pulling out before the first pouring or pouring in order to expose the opening.
  • a flat cover is known from US Pat. No. 5,101,999, which was made in one piece using injection molding technology. It comprises a base part with a central opening, which is marked by a circumferential web, a hinged lid and a guarantee seal, which is arranged in the central opening.
  • This flat lid is characterized by several special features.
  • the peripheral web is shaped at one end into a pouring spout.
  • the guarantee seal is designed in such a way that it can be pressed down and thus opens the container. It is hinged to the same end of the base part as the lid and to the other Secured at the end via a thin bridge which must be broken through for the first opening.
  • connection to the base part there is a ventilation hole, which should improve the casting behavior in addition to the pouring spout.
  • the disadvantage is that the guarantee seal is difficult to impress.
  • the manufacturing effort and thus the costs are disproportionately high.
  • the invention has for its object to find a plastic closure that is structured as simple as possible despite improved casting behavior in order to keep unit costs to a minimum for the purpose of mass production.
  • the object is achieved by a plastic closure with the features of claim 1. It is provided in a generic plastic closure that the guarantee seal is formed on the back as a pouring aid after opening.
  • a pouring aid is also integrated into the plastic closure via the integrated guarantee seal.
  • the guarantee seal In the delivery state, the guarantee seal is initially connected to the lower part on tear lines. After opening the closure for the first time, the plastic material tears at these tear lines and the rubble opening is released.
  • the guarantee seal is preferably connected to the lower part via a connection, for example a film hinge, in such a way that it can be swung out of the lower part as an axis of rotation by a pivoting movement with the film hinge to the lower part.
  • the connection between the guarantee seal and the lower part, which serves as the axis of rotation, is preferably undetachable, in contrast to the connection or connections which are irreversibly released when the closure is opened for the first time.
  • This connection is arranged on the side of the lower part to which the contents of the container are to be poured or poured out.
  • the side of the guarantee seal facing the container before the guarantee seal is opened is designed as a pouring aid. If the guarantee seal is opened far enough, the contents of the container are removed from the container via this rear side of the guarantee seal, which is designed as a pouring aid.
  • the upper part and lower part of the curative substance fastener can either be connected to one another via a connection or they can also be separate components which are mounted, for example, via a snap-in connection or screw connection.
  • the lower part can be connected to the container in any way.
  • the method of attachment is determined, among other things, by the material of the container. Examples include metal or plastic containers to which the plastic closure could be welded, or glass or cardboard containers with which the curative substance closure could be glued.
  • the plastic closure according to the invention is suitable for containers of any material.
  • a handle is attached to the guarantee seal, which facilitates gripping and thus opening the guarantee seal.
  • the lower part preferably has a recess into which the guarantee seal fits after being opened, so that it is locked for stabilization during pouring or pouring.
  • an embodiment has a lateral guide that leads to the opened guarantee seal. It prevents the contents of the container from being poured out or poured out lateral escape and thus ensures targeted removal of the contents of the container.
  • the plastic closure is preferably designed as a flat closure, i.e. the height of the closure is small compared to the dimensions of the base area of the closure. This ensures good stackability, particularly in the case of rectangular containers.
  • the plastic closure can have any basic shape, be it round, square or oval. It has proven to be advantageous to choose a triangular basic shape in which the connection between the guarantee seal and the lower part, which serves as the axis of rotation when the guarantee seal is opened, is arranged at the base of the triangle.
  • a triangular basic shape in which the connection between the guarantee seal and the lower part, which serves as the axis of rotation when the guarantee seal is opened, is arranged at the base of the triangle.
  • FIG. 4 shows a triangular flat closure with a broken guarantee seal
  • Fig. 5 shows a triangular flat fastener with lateral guidance
  • Fig. 6 shows a triangular flat closure with a recess for locking the pouring aid.
  • the embodiments shown below are based on a plastic closure with a triangular basic shape. It is designed as a flat fastener, in which the height of the fastener is low compared to the dimensions of the triangle sides. Upper part 2 and lower part 1 are connected
  • Fig. 1 a triangular flat fastener is shown in the closed state.
  • the upper part connected to the lower part 1 via the connection 3 lies firmly on the lower part 1.
  • the upper part 2 of the triangular flat closure shown in FIG. 2 is slightly raised so that the guarantee seal 4 can be seen underneath, which is provided with a loop-like handle 5.
  • the top part 2 is completely opened, one can see the guarantee seal 4 in the middle of the bottom part 1, which, like the entire plastic closure, has essentially a triangular shape and completely the pouring opening 9 underneath (see FIGS. 4-6 ) covered.
  • the guarantee seal 4 On the top of the guarantee seal
  • a handle 5 in the form of a loop is attached to the triangle tip.
  • Fig. 4 shows the triangular flat closure after the guarantee seal 4 has been broken for the first time opening. To do this, you grab the handle 5 and pulls on it. Since the guarantee seal 4 is easily detachably connected to the lower part 1 at the triangle tips, these connections loosen along the tear lines produced by material weakening, while the connection between the guarantee seal 4 and lower part 1 does not come loose. There guarantee seal 4 and lower part 1 are connected via a film hinge 6. Because of this arrangement, the guarantee seal 4 executes a pivoting movement in the direction of the arrow around the film hinge 6 when the guarantee seal 4 is pulled over the handle 5.
  • the guarantee seal 4 is folded out vertically. Its back is shaped in the form of a pouring spout as a pouring aid 10, via which the contents can leave the container if one tilts it.
  • Fig. 6 shows a further embodiment of a triangular flat fastener, which differs from the embodiment shown in Fig. 5 in that the lower part 1 has a recess 7, which is arranged in the circumferential web 8, which serves as a lateral guide.
  • the unfolded pouring aid 10 fits exactly into the recess 7 and can be clamped between the edges of the recess 7, so that the pouring aid 10 is stabilized in terms of movement and thus the pouring behavior of the plastic closure is increased.
