Definitions

  • the invention relates to an assembly of a film container for storing a one- or multi-component mass and a squeezing device for the film package, wherein the film package at least one non-inherently stiff elongated film bag and an inherently rigid head part with at least one attachment portion for one end of the film bag and an outlet opening for having the outlet of the mass and wherein the squeezing device has at least one receptacle for insertion of the at least one film bag. Furthermore, the invention relates to a film package for such an assembly, with at least one non-rigid inherent elongated foil pouch and a self-rigid head part with at least one attachment portion for one end of the foil pouch.
  • Such film packages have been proven in the past as packaging for chemical compositions such as mortar, foam, dowel or sealants, which consist of one or more components. Especially with respect to cartridges they are characterized by a cheaper and easier production and a lower after use to be disposed of material content.
  • the film container is usually in a receptacle of a squeezing device, such as a dispenser, inserted.
  • a squeezing device such as a dispenser
  • the one- or multi-component mass is squeezed out through an outlet opening in the head part and then passed (at least in the case of a multi-component mass) for better mixing through a mixer attachment with a mixer element.
  • a gap is required between the film outer wall and the inner wall of the receptacle.
  • the film of the film bag When emptying the Foliengebindes, such as by means of a displaceable in the receptacle piston, the film of the film bag or is stretched, whereby it comes to rest the film to the inner wall of the recording. In this case, the film is expanded, and the possibly different films of the individual bags experience different voltages, which lead to uneven pressing of the various components when pressure is released.
  • This expansion and resetting of the foil bag is also referred to as a pump and leads in particular to the startup behavior to errors in the mixing ratio.
  • the at least one foil bag in the filled state has the shape of a truncated cone, the diameter of which decreases starting from the attachment portion in the direction of its longitudinal axis, and that the at least one receptacle a in particular complementary to Foil bag formed, frusto-conical inner peripheral wall, wherein the at least one foil bag in the fully inserted state rests flat against the inner peripheral wall of the receptacle.
  • both the at least one foil pouch and the associated receptacle have slightly inclined peripheral walls, which makes it possible to insert the foil pouch into the associated receptacle even without providing a joining gap.
  • the film outer wall is flat against the inner wall of the receptacle, whereby a stretching and returning the film bag when emptying is reliably prevented.
  • the inner peripheral wall of the receptacle provides in the fully inserted state, a complete support of the foil bag, so that even under pressure can not experience expansion and thus no default occurs. In this way, the unwanted pumping is avoided.
  • a much easier insertion is possible due to the slopes.
  • the cone angle or opening angle of the truncated cone is in the range of 0.1 ° to 10 °, in particular from 2 ° to 6 °.
  • the or the foil bag and the receptacle (s) are thus provided only with a slight chamfer, whereby the insertion is facilitated and can be dispensed with a joint gap.
  • the same time allows only a slight inclination of the peripheral walls reliable squeezing of the contained mass (s) with the help of (ever) a guided in the recording piston. Since the diameter of the film bag only slightly increases from the end at which the piston engages to the other end fixed to the attachment portion of the film bag, even when a conventional piston is used, the film bag is completely emptied.
  • the film package has a first film bag and a second film bag arranged next to the first film bag for components of a multicomponent mass stored separately from one another, wherein both film bags have a frustoconical shape are formed.
  • the film container is suitable for storing a two-component mass, which is mixed together only during pressing.
  • the head part then has a first fastening section for one end of the first film bag and a laterally arranged second attachment section for one end of the second film bag, in particular of each film bag, a passageway in the head part is provided and the passageways in the head part open into a common outlet opening ,
  • a mixer attachment is usually screwed onto the outlet opening, which ensures a simple mixing of the two or more components stored in the two foil bags directly during the extrusion.
  • the squeezing device preferably has a first receptacle for the first foil bag and a laterally arranged second receptacle for the second foil bag, both receptacles having tapered inner circumferential walls in the direction of their longitudinal axis. This ensures reliable surface support for the outer walls of both foil bags.
  • the two film bags on the same cone angle and thus the same inclination relative to the longitudinal axis, which is particularly favorable in terms of manufacturing technology with respect to the associated recordings.
  • the two truncated cone foil bags may have different cone angles. It is crucial that the respectively associated receptacle has a cone angle matched to the cone angle of the film bag.
  • the two film bags are made of films with different mechanical properties. Due to the full-surface support the foil bag in the respective receptacle is reliably prevented from expanding and dividing the film bag, so that no tuning of the mechanical properties of the different foil bags is required in the embodiment according to the invention.
  • the first film bag has a larger diameter over its entire length than the second film bag.
  • the first foil bag thus has a greater capacity for the same length, which allows a ratio of the two components deviating from the ratio of 1: 1.
  • any mixing ratio of the components can be realized.
  • a film container of the type mentioned in which the at least one foil bag in the filled state has the shape of a truncated cone, the diameter of which decreases starting from the attachment portion in the direction of its longitudinal axis.
  • a film package can be easily insert into the receptacle of a squeezing even without providing a joint gap and allows the film bag in the fully inserted state flat against an inner peripheral wall of the receptacle, whereby the unwanted expansion and return of the film bag when squeezing the mass of the Film bag is reliably prevented.

Both foil bags 16, 18 are fixed permanently on the head part 20.
  • two passageways 30, 32 are formed in the head part 20, each connecting one of the film bags 16, 18 with a common outlet opening 34. On this usually a mixer attachment (not shown) is screwed.
  • Both film bags 16, 18 have the shape of a truncated cone, the diameter of which decreases from the respective attachment portion 22 and 26, respectively, in the direction of a longitudinal axis L of the film bag 16, 18.

  • the first film bag 16 has along its entire length a larger diameter than the second film bag 18, as can be seen from the figures. Consequently, the first foil bag 16 contains a larger volume of the two-component mass, whereby this component predominates in the ready-mixed mass. In principle, the mixing ratio of the two-component mass can be adjusted via the volume or diameter ratio of the film bags 16, 18.
  • the squeezing device 14 which is only partially shown in the figures (the representation of the actual squeezing mechanism, for instance in the form of one or more pistons, has been dispensed with), has a first receptacle 36 for the first Foil bag 16 and a laterally arranged next thereto second receptacle 38 for the second film bag 18. Both receptacles 36, 38 have a complementary to the associated foil bag 16, 18 formed, frusto-conical inner peripheral wall 40 and 42, respectively tapered in the direction of the longitudinal axis L.

  • Figure 2 shows a middle position in which the film package 12 is inserted about halfway into the squeezing device 14. Due to the frusto-conical design of both the foil bag 16, 18 and the receptacles 36, 38, the provision of a joint gap, as is known from conventional circular cylindrical foil bags, not necessary here. Due to the inclination of the walls involved a simpler insertion is also possible.
