Definitions

  • the invention relates to a piston for discharging a flowable component from a cartridge according to the preamble of claim 1.
  • a piston for discharging a flowable component is described from a cartridge having a base body and a venting element.
  • the main body has a component side, an operation side and a passage connecting the component side and the operation side with a through hole.
  • the venting element has an inner connecting element, by means of which the venting element can be connected to the base body, and a pin, which is partially arranged in the passage opening of the base body.
  • the inner connecting element and the pin are connected by means of a spring element, which in turn is connected along a connecting line with the inner connecting element.
  • the pin of the venting element can assume a sealing position and a ventilation position.
  • the pin In the sealing position, the pin is aligned along an axial direction and closes the passage opening airtight.
  • the pin In the ventilation position, the pin is arranged in relation to the main body so that an air exchange between the component side and the actuating side is possible through the passage.
  • the venting element is arranged and designed so that the spring element pushes the pin in the sealing position.
  • the flowable component is usually filled into the cartridge via an inlet opposite the outlet. Subsequently, the piston is inserted into the cartridge and thus the cartridge closed in the direction of the inlet. If possible, there should be no air between the component and the piston, as otherwise components of the air may react with the component and thus adversely affect the quality of the component. That is why during or at least at the end of insertion of the piston into the cartridge, the venting member pin is brought to the venting position so that the air between the component and the piston can escape through the passage and the cartridge is vented. To set the ventilation position, the pin is pressed against the restoring force of the spring element in the direction of the component side and thus allows an exchange of air through the passage. After filling, the pin should remain as secure as possible in the sealing position and thus seal the component airtight in the direction of the inlet of the cartridge.
  • the piston is displaced in the axial direction in the direction of the outlet of the cartridge.
  • the piston is acted on the actuation side by a plunger with an actuating force.
  • a plunger with an actuating force.
  • the piston has a base body and a venting element.
  • the main body has a component side, an operation side and a passage connecting the component side and the operation side with a through hole.

  • the inner Connecting element and the pin are connected by means of a spring element, which in turn is connected along a connecting line with the inner connecting element.
  • the pin of the venting element can assume a sealing position and a ventilation position. In the sealing position, the pin is aligned along an axial direction and closes the passage opening airtight. In the ventilation position, the pin is arranged so that an exchange of air between the component side and the actuation side over the passage is possible.
  • the venting element is arranged and designed so that the spring element pushes the pin in the sealing position.
  • the spring element is designed so that it encloses in the sealing position of the pin at the connecting line to the inner connecting element in the direction of actuation side an angle of at most 80 ° with the axial direction.
  • the inventive design of the piston ensures in particular advantageous manner to ensure that the pin is safely returned to the sealing position even after repeated adjustment of the ventilation position. This is particularly advantageous if, as described above, the ventilation position is also set when discharging the component and in addition the component is not discharged all at once, but several times in smaller portions, with each discharge of the piston in the axial direction towards the outlet of the cartridge becomes.
  • the line is to be understood on the side facing toward the actuating side of the venting element, on which the inner connecting element merges into the spring element. If a so-called rounding radius is formed between the connecting element and the spring element, then the connecting line at the end of the rounding radius results in the direction of the spring element.
  • Said angle is determined in particular in a section centrally through the pin parallel to the axial direction. It then results between a tangent at a point of the connecting line to the aligned in the direction of the actuating side contour of the spring element.
  • the spring element has, for example, a thickness of 0.3-0.8 mm, in particular 0.4-0.5 mm.
  • the flowable component is designed, for example, as an adhesive.
  • the inventive pistons are also often used in so-called two-component cartridges that can accommodate two different components separately.
  • the two components are mixed together during discharge, whereby a chemical reaction occurs, which usually leads to the curing of the mixed components.
  • Such two-component cartridges can be used for example in the dental field for so-called impression materials or in the construction sector for so-called chemical dowels.
  • the two individual cartridges of a two-component cartridge can be arranged side by side or one inside the other.
  • the piston according to the invention can thus have a cylindrical basic shape or an annular basic shape.
  • a piston having an annular basic shape is also referred to as an annular piston.
  • the main body and the venting element are in particular designed as two separate components, which are combined prior to insertion into a cartridge to a piston according to the invention.
  • the pin of the venting element has in particular a cylindrical basic shape, wherein its diameter changes, in particular in the axial direction, resulting in a conical section of the pin.
  • the pin tapers in particular toward the actuating side of the piston.
  • the outer contour of the conical section of the pin corresponds in particular to the inner contour of the passage opening, so that in the area results in a sealing surface between the pin and passage opening, which allows a secure sealing of the passage opening in the sealing position of the pin.
  • the spring element in the sealing position of the pin at the connecting line to the inner connecting element in the direction of the operating side encloses an angle between 65 ° and 75 °, in particular between 69 ° and 71 ° with the axial direction.
  • the spring element in the region of the connecting line to the connecting element on a frustoconical contour results in a particularly high biasing force on the pin.
  • the inner connecting element of the venting element has a mainly cylindrical basic shape and is connected via an inner latching connection with the base body.

  • the inner connecting element is arranged between the outer connecting element and the pin. This allows a particularly stable and secure connection between the venting element and the body.
  • the outer connecting element can basically be constructed the same as the inner connecting element. But it is also possible that the connecting element has a bulge, which is designed so that they can no longer happen after connection to the body further bulging of the body. In this case, the outer connecting element engages in the connection with the base body in this.
  • the base body and the venting element are produced by means of an injection molding process, in particular of different materials.
  • the piston can be produced on the one hand cost and the material can be adapted exactly to the requirements.
