Definitions

  • the invention relates to a cartridge for dosing a paste or the like, with a sleeve which is at least predominantly in the form of a hollow cylinder and has an operating opening and an outlet opening, with a rod, a piston arranged axially displaceably in the hollow cylindrical part of the sleeve by means of the rod and a stopper which closes the outlet opening, the stopper being arranged in part sealingly within the outlet opening.
  • Such cartridges are commercially available in some embodiments today.
  • the paste contained in such cartridges has a consistency that can be described as viscous to mushy.
  • Many of these pastes are used as hardeners for polyester or epoxy resins or the like. It is therefore necessary that this paste can be dispensed from the cartridges in as precisely metered amounts as possible.
  • pastes are offered in the simplest form in tubes made of thermoplastic material.
  • exact dosing is not possible with these tubes.
  • the welding of the part of the tube opposite the outlet opening which is necessary after the tubes have been filled, is often dangerous because the paste inside the tube heats up during welding and thus expands, which can cause the tubes to burst.
  • cartridges with pastes have been available for some time, in which the required amount of paste can be pressed out of the outlet opening by means of a piston and a rod, which is usually supplied.
  • the outlet opening is usually closed with a stopper or a cap.
  • the operating side that is: the side of the cartridge through which the rod is inserted into the cartridge is also closed with a cap or a stopper.
  • the cap or the stopper on the operating side must be removed before the rod is inserted in the cartridges known today.
  • the piston cross section has smaller dimensions than the inner cross section of the sleeve. Due to the gap formed between the sleeve and piston, the air can escape in the direction of the operating opening. In this way, it cannot be avoided that a small part of the paste adheres to the wall of the sleeve when the piston is moved in the direction of the operating opening. The dosage is also inaccurate again.
  • the object of the invention is to reduce the disadvantages described above as much as possible and to provide a cartridge of the type described above in which the entire paste can be metered as waste-free as possible. The risk that the person using the cartridge comes into contact with the paste should be largely avoided.
  • this object is achieved by a cartridge of the type described above in that the operating opening of the cartridge is positively and positively closed by a cap, and the cap has an axial guide bore for the rod.
  • the non-positive and positive closure prevents the cap from being removed. In this way a Inexpert g effleßes intervention is out of the cartridge.
  • the axial guide bore prevents the rod to be inserted from coming into contact with the inner wall of the sleeve.
  • the non-positive and positive closure between the cap and the sleeve is advantageously ensured in that the sleeve in the vicinity of the operating opening has a bead which extends over the entire circumference of the outer jacket, and the inner wall of the cap has a circumferential, approximately the same geometric shape how the bead has groove, and the cap comprises the hollow cylinder of the sleeve from the outside in a non-positive and positive manner.
  • a cap has the advantage that it can be attached after the cartridge has been filled, but cannot be removed afterwards.
  • the guide bore of the piston is connected to the guide bore of the cap via an axially arranged tube having approximately the same internal cross section as the guide bore of the piston and the cap, the tube having at least one section with a perforation distributed over the circumference.
  • the buyer is assured that the cartridge he has purchased has not yet been used.
  • the perforation makes it easy to separate the piston from the cap with a strong push using the rod provided.
  • the guide bore of the cap can either be closed by a thin film which can be pierced by means of the rod or by a plate which is connected to the guide bore by means of a plurality of webs.
  • a thin film which can be pierced by means of the rod or by a plate which is connected to the guide bore by means of a plurality of webs.
  • the loss of paste can be limited by the fact that the side of the piston facing the outlet opening has the same geometric shape as the inner wall of the end section of the sleeve towards the outlet opening, in which the hollow cylinder forming the sleeve is reduced towards the outlet opening.
  • the piston has at least one sealing ring which extends over the circumference of the piston.
  • the piston in order to allow the air contained in the cartridge to escape in the direction of the service opening, but at the same time preventing the paste from adhering to the inner wall of the sleeve, it is very advantageous for the piston to have a plurality of pieces extending over the circumference of the piston at least one point has interrupted sealing rings, the interruption points of adjacent sealing rings being arranged offset. In the event that the piston is produced from a thermoplastic material by injection molding, these sealing rings can also be cast on during injection molding.
  • the outlet opening should not be closed with a cap, because in the case of protruding paste when ver close the outlet opening, the protruding part of the paste is squeezed outwards, as a result of which the paste can easily be touched. Therefore, it is particularly favorable if the part of the stopper arranged in the outlet cross-section in the axial direction from the outside inwards first has a cylindrical or a spherical section which seals the outlet opening and then has a conical section.
  • the conical part of the stopper advantageously has the shape of a truncated cone.
  • the cartridge parts are expediently made of thermoplastic material.
  • Polypropylene, polyethylene, polyisobutylene, PVC, polyamide, polyester or polycarbonates, for example, can be used as thermoplastic materials.
  • the sleeve should be made of transparent material. All materials which are transparent or at least allow the paste located in the sleeve to shine through to the outside are considered to be transparent in the sense of the present invention.
  • markings can consist, for example, of lines applied perpendicularly to the axial direction and of the numbers and letters (for example: 20 ml) indicating the amount dosed up to this line.
  • the rod has at least one groove running in the axial direction.
  • the cartridge according to the invention is preferably filled with paste, in a manner which is particularly advantageous for the invention, with peroxide paste.
  • the transparency of the material of the sleeve is advantageously increased if matting agents or dyes are added to the paste or the piston.
  • the sleeve 1 shows a cross section of a cartridge according to the invention. Except for a short section 2, the sleeve 1 has a hollow cylindrical shape.
  • the cross section of the sleeve can be circular, elliptical, square or rectangular.
  • the cross section of the sleeve 1 is reduced towards the outlet opening over a short section 2.
  • a plug 6 is arranged in the outlet opening, part of which (sections 3 and 3) within the outlet opening the other part (section 5) is arranged outside the outlet opening.
  • the part of the plug 6 (section 5) arranged outside the outlet side has the shape of a disk and is connected to the outer jacket of the sleeve 1 via a strip 7.
  • the part of the plug 6 arranged in the outlet opening first has a spherical section 5 from the outside inwards and then a conical section 3 in the form of a truncated cone.
  • a cap 8 closes the sleeve 1 in a non-positive and positive manner.
  • the cap 8 encloses the sleeve 1 from the outside.
  • the sleeve 1 has on the operating opening side a bead 9 extending over the circumference of the sleeve 1 and the cap 8 on the inside has a circumferential groove which has the same geometric shape as the bead 9.
  • a piston 10 is arranged inside the sleeve 1.
  • the piston 10 has four sealing rings 13 which extend over the circumference of the piston 10. These sealing rings 13 are each interrupted at one point on the circumference of the piston 10, the interruption point of adjacent sealing rings 13 being offset by 180 ° (not in the figure) shown).
  • the side of the piston 10 facing the outlet side has the same geometric shape as the short section 2 of the outlet opening.
  • FIG. 2 shows a rod 14 which has a cross-shaped cross section according to FIG. 15.
  • the rod 14 is truncated lens-like at one end 16.
  • the cartridge is filled in a commercial form with a paste, for example with peroxide paste. If, after dosing, the paste protrudes on the outlet side, it can be pressed back into the sleeve with the conical section 3 of the stopper 6.
  • the disk 6 of the stopper 6 has larger dimensions than the outer jacket of the outlet opening, which additionally ensures that the user of the cartridge cannot come into contact with the paste.
  • the cross-shaped cross section 15 of the rod 14 ensures that, due to the four existing axially extending grooves, the air escaping through the piston escapes and the amount of air required by the further movement of the piston 10 can flow into the sleeve 1.
  • the rod 14 When the cartridge is started up, the rod 14 is inserted into the guide bore 11, the piston 10 being detached from the cap 8 at the fastening point by a strong, short impact.
  • the paste on the sleeve 1 can then be dosed with sufficient accuracy by means of markings (not shown).
  • the cartridge is made of translucent PVC and the paste has been mixed with a dye before filling.
