Definitions

  • the invention relates to a toilet basket with a container area for receiving a toilet active ingredient and with a holding device for attaching the toilet basket to a toilet bowl.
  • the holding device is thermoformed from a plastic film.
  • Toilet baskets are commonly used for cleaning toilet bowls.
  • a toilet basket is usually attached to the edge of the toilet bowl with the help of a holding device.
  • flushing water flows through the toilet basket so that part of the toilet active substance is dissolved and distributed in the toilet bowl with the flushing water.
  • EP 3214232 A1 discloses a toilet basket which is formed from a film by thermoforming and stamping.
  • the toilet basket has a holding device in the form of clamping units with which the toilet basket can be positioned in the operating position in or under an edge of a toilet bowl so that it can be clamped.
  • the disadvantage of such a design is that the toilet basket is not positively but only non-positively fixed by the clamping units and the toilet basket could solve due to a low clamping force between the clamping units and the toilet bowl.
  • Such a toilet basket also has the disadvantage that the clamping units have to be positioned between two opposite sides and the range of use is thus limited.
  • a toilet basket is known from EP 0 773 330 A1, in which the holding device is designed in the form of a flat foil blank made of plastic, from which a U-shaped bracket can be formed.
  • the blank has a plurality of parting lines, a first bending area and a second bending area. By bending or folding along the bending areas, the blank surfaces separated from one another by dividing lines can be reshaped into the U-shaped bracket.
  • the U-shaped bracket has an inner portion, a support portion, and an outer portion.
  • the U-shaped bracket hangs over the edge of the toilet bowl, with the inner section lying against an inside of the upper edge of the toilet bowl, the carrying section lying on the upper side of the upper edge and the outer section reaching behind the upper edge laterally from the outside.
  • the first bending section is arranged between the inner section and the supporting section.
  • the second bending section is between the support section and the outer section. Because of the elasticity of the bending sections, there is a certain restoring force that pushes the U-shaped bracket back into the unloaded state of rest of the flat blank.
  • the U-shaped bracket is pressed against the upper edge of the toilet bowl by the restoring force and lies firmly there.
  • undesired stress peaks occur at the points between the dividing lines and the bending areas due to the notch effect.
  • the bending areas of the film blank are very short or small, so that the forces that the U-shaped bracket can absorb are small.
  • the U-shaped bracket is therefore unstable and can easily break.
  • the present invention has therefore set itself the task of providing a toilet basket with a reliable holding device which can be produced simply and inexpensively by thermoforming a film.
  • the inner section, the carrying section and the outer section lie on top of one another and form a folded package in which the outer section lies between the inner section and the carrying section. Accordingly, the outer section lying inside the package is covered by the inner section and the carrying section.
  • the support section or the outer section has a first overhang relative to the inner section. The first projection serves to grip the carrying section and/or the outer section and to be able to introduce a torque relative to the inner section.
  • the first projection is preferably formed in that the outer section has a greater width than the inner section.
  • the first overhang comprises that surface of the outer section which protrudes over the surface of the inner region. A surface is thus formed which is easily accessible from the outside and which can be subjected to a force.
  • the first overhang can also be formed in that the support section has a greater width than the inner area.
  • the first projection comprises that surface of the carrying section that protrudes over the surface of the inner area.
  • the first projection can be at a distance from the first bending area, so that a lever is set between the first projection and the first bending area.
  • a force can be applied by pressing with the thumb on the first protrusion.
  • the lever and the force can set a moment at the first bending area, which allows the opening of the first bending area.
  • the invention according to patent claim 1 provides that the toilet basket comprises a bracket-shaped holding device which is folded in before use.
  • the space required for the toilet basket during transport and storage is correspondingly small.
  • the first projection which can be designed as a tab, is formed by the different widths of the sections of the U-shaped bracket. For example, there may be a constriction of the carrying section, in which case the outer section may be wider than the carrying section. Despite the different widths of the sections, high strength is possible, particularly in the bending area.
  • the holding device can be opened up by the user in a simple manner and without tools.
  • the resting state of the holding device means the state in which essentially no internal or external forces are present on the holding device.
  • unfolding the holding device is brought from the idle state into an unfolded state.
  • restoring forces can be present in the holding device. Restoring forces are caused by the deformed bending areas.
  • the inner section and outer section can be pressed laterally against the upper edge by the restoring forces.
  • the U-shaped bracket does not hang loosely over the upper edge, but is additionally fixed by clamping forces.
  • the inner portion, the support portion and the outer portion may be parallel or substantially parallel to each other when at rest.
  • An exactly parallel arrangement is present when a bending angle of the first bending area and a bending angle of the second bending area are each 0°.
  • the inner section, the carrying section and the outer section it is also possible for the inner section, the carrying section and the outer section to lie on top of one another when the holding device is in the idle state and the bending angles are not equal to 0°.
  • the bending angle of the first bending area can be 5° to 20° in the resting state. Both bending angles are preferably less than 10°.
  • the sum of the bending angles of the first and second bending areas is less than 20°, preferably less than 15°. The smaller the bending angles, the more compact the holding device is at rest. In the unfolded state, if an exact U is taken as a basis, the bending angle of each bending area is 90°.
  • the toilet basket according to the invention is hung on a toilet bowl in the unfolded state of the holding device.
  • the holding device of the toilet basket forms a U-shaped bracket through the inner section, the carrying section and the outer section when it is completely unfolded.
  • the holding device is arranged on the toilet bowl in such a way that the inner section and the container area adjoining the inner section lie in the inner area of the toilet bowl.
  • the carrying area comes to rest on the top of the toilet bowl.
  • the outside area extends on the outside of the toilet bowl. Due to the restoring forces, the inner section and the outer section pressed sideways against the top edge of the toilet bowl. In this clamped position, the bending angle is 90° only in special cases. Depending on the dimensions of the upper edge and the individual sections of the holding area of the toilet basket, the bending angles that ultimately occur in the bending areas deviate from 90°.
  • the toilet basket according to the invention can be produced as follows: In a first step, the holding device is thermoformed from the plastic film. The inner section, the first bending area, the supporting section, the second bending area and the outer section extend in this sequence, adjoining one another in one plane or essentially in one plane without any appreciable angles between the individual sections.
  • the second bending area is deformed in such a way that the outer section is folded onto the carrying section.
  • the second bending area is heated.
  • a pin or thin rod temporarily placed in the bending area can be used to define a folding axis.
  • the unit consisting of the outer section and the carrying section can be folded onto the inner section.
  • the second bending section must be deformed. Heat is preferably also introduced here so that the second bending region can be plastically deformed.
  • the first overhang can at the same time represent an overhang of the outer section in relation to the carrying section in order to introduce a force for the unfolding of the second bending region.
  • Such a configuration allows the holding device to be designed in a particularly simple manner, because only a projection is necessary in order to fully unfold the holding device.
  • the first overhang thus also forms a means for setting a moment at the second bending area.
  • the outer section has a second overhang in relation to the carrying section in order to introduce a force for opening the second bending region.
  • first bending area and the second bending area run essentially parallel. This means that the bending axes or folding axes are essentially parallel.
  • the width of the first bending area corresponds to the maximum width of the holding device.
  • the width corresponds to the second Bending area of the width of the first bending area.
