Definitions

  • the invention relates to a dosing pen for precise dosing of adhesives, paints, medicines, cosmetics or the like.
  • Adhesive containers for cyan adhesives are usually made of polyethylene, especially HDPE, and have a holding volume of about 10 ml to 100 ml of adhesive.
  • the container which can be used in particular for receiving superglue, may have a predominantly cylindrical, conical and / or spherical or concave shape, so that it can be stored in an upright position.
  • cyanoacrylate adhesives do not have a sufficiently high shelf life in thin-walled, easily squeezable polyethylene containers because the volatiles of the adhesives can diffuse through the container walls.
  • the invention has for its object to provide a metering pen, which has a high stability and allows a good metering of the adhesive with little manual effort.
  • the liquid held in the pen or container can be well dosed with a low pressing force.
  • the groove or slot-like depression in the wall of the receptacle, which extends in the axial direction of the container and in particular from the bottom to a container shoulder can rich, allows the dispensing of the liquid with the low pressing force at the same time good dosing.
  • the diffusion rate from a container is inversely proportional to its wall thickness x. So 5 to 20g bottles with 1.2mm HDPE wall thickness and more can only be pressed with more than unreasonable 50N. By carrying out the slot in the bottle or the metering pin according to the invention can be remedied here.
  • the slot or a recess from the lower end of the container in particular to shortly before the shoulder or up to her zoom or even the shoulder is formed across.
  • the slot can have a depth of at least 5mm, especially at least 10mm.
  • a nozzle with an outlet opening or a neck with thread or bounce ring can be formed at the shoulder of this container.
  • this first nozzle has an external thread for a special cap.
  • a known nozzle or a dosing head can be screwed on the thread of a neck.
  • a dosing sleeve may be integrally formed with a sealing pin on the shoulder, on which a known, rotatable rotary sleeve is snapped.
  • the slot formed by the container wall can be brought together in a radially outward direction relative to a longitudinal axis of the container, that is to say towards the outside, to form a narrow gap in order to limit the adjustment path or the compressibility of the container. This also limits the dosage per dosing process. This is particularly important when using a highly reactive superglue, since the adhesive should not be brought to undesirable sites or on the skin of a user.
  • the metering pin according to the invention may have a metering tip or nozzle adapted to the application. This can be designed as a simple, open nozzle or as resealable rotary tip.
  • the metering pin according to the invention is produced in particular by an injection molding process.
  • the container of the dosing pin according to the invention may either have a closed bottom or be provided with an open lower end which is closed with a stopper.
  • a stopper In the former case may be provided on the side facing away from the closed bottom of the container, a thread for coupling with an adapter on which the metering tip is formed, or a bouncing ring, which is followed by a cap with dosing tip.
  • the container is preferably provided on the side facing away from the stopper with an integrally molded metering tip or nozzle.
  • the plug for closing the lower open end of the container has, in a specific embodiment, a base plate which is either continuous or provided with the continuation of the slot in the container.
  • At least one inner sealing sleeve is formed on this plate, which sits positively in the large opening at the end of the container and clamped there and or welded.
  • an outer sealing sleeve to the plate of the plug. It prevents by its permanent pressure on the container wall in the region of the lower open end of the container inward - ie against the pressure of the inner sealing sleeve - stress cracks, which could occur quickly when using fast-drying, aggressive adhesives.
  • the axial recess is merged into a single gap.
  • the gap is limited in its width in order to limit the stroke and thus the dosage per dosing. This is not unimportant for highly reactive superglue to prevent adhesion to unwanted areas or even to the skin. So far, this has only been possible with additional, elaborate levers or buttons on a pen. The dosability of only one drop also plays a very important role in eye drops.
  • a rotatable adjusting ring which limits the stroke differently with different width cams in the inner contour. It is snapped onto the container and can be rotated slightly around the main axis. In this case, different width cams spring into the gap or slot, whereby its effective stroke is adjustable.
  • the most important feature of this adjustment ring is that the different width cams definitely specify the stroke of the slot, so almost the difference between slot width and Nockenke is then the resulting actual stroke. So you can apply cyanoacrylate adhesive or eye drops exactly dropwise, optionally also two or three drops.
  • the container of this type of dosing pin with plug is to be manufactured purely by injection molding, as follows:
  • the solution provides that the bottom of the bottle is sprayed open. Again, it is an injection molded part, whose technology is well mastered and not the very large tolerances afflicted blowing technique.
  • the slot extends in the container as a dent to her shoulder or through, so that a matching mold pin in the injection mold without undercut remains and can be pulled axially out of the nozzle in a first version.
  • Another third version is a glue stick having an injection molded slotted and asymmetric nozzle container which is offset from the major axis, laterally from a relatively large slit. Also, the slot itself may be offset asymmetrically from the main axis.
  • the slot runs in the container up to their shoulder or through, so that a matching molding pin in the injection mold without undercut remains and can also be pulled out of the nozzle.
  • the deepest slot can be realized, which results in a noticeable effect when pressing the container, so easier squeezability is achieved, has been proposed in one version, the nozzle with an offset asymmetrically outward and away from the slot , With this gimmick you can on the one hand easily pull the stylus out of the nozzle and at the same time realize small cavities of 3g and 5g slot depths of about 10 mm and more.
  • a particularly deep slot is possible, which leaves the hard HDPE bottle with wall thickness of more than 1.2 mm pleasantly soft.
  • easily pressed bottles made of transparent PC, PET, PBT, etc. are possible.
  • a venting channel is formed in a special embodiment in the outer contour of the inner and optionally the outer sealing sleeve. It can end just before the plate of the plug.
  • the container of this adhesive and dosing with universal adapter is to be made purely by injection molding, with a closed bottom at the bottom and with a widening towards from the bounce ring or a thread at the top.
  • the upper end is shaped so large that the molding pin can still be removed from the mold without difficulty in the direction of the nozzle, ie the upper end is effectively equal to or larger than the container of the pencil.
  • This type of container according to the invention is an injection-molded part whose technology is well-controlled and not the blast technique associated with large tolerances.
  • the continuous, axial slot in the container in this case extends to or through the shoulder of the container.
  • the aim of a low pressing force and easy metering is achieved in that a recess from the bottom of the bottle is formed in the direction of the shoulder, which is led to the outside to a narrow gap together.
  • this is a partially wound oval flat bottle, here called the bottle ring.
  • the axial recess is merged into a gap.
  • the gap is limited in its width in order to limit the stroke and thus the dosage per dosing. This is not unimportant for highly reactive superglue to prevent adhesion to unwanted areas or even to the skin. So far, this has only been possible with additional, elaborate levers or buttons on the bottle.
  • the bottle with its recess and the gap is to be made from a preform in a Spritzblas- method.
  • the preform also called preform, already carries the thread and is introduced into a preheated tool and blown there with compressed air in the special contour, wherein in the tool interior, a mandrel protrudes with a web which coins the recess and the gap.
  • the invention also has a child safety device for superglue bottles or a dosing with child safety to the object.
  • a child safety device for superglue bottles or a dosing with child safety to the object.
  • the spring tongues can be designed as webs, ergonomic sleeve segments or as parts of an oval cap. Between the spring tongues and the cap sleeve is ever a slot that begins at the bottom of the cap. As a rule, this slot runs on the length of a third to two-thirds of the cap length.
  • the nozzle-bearing adapter On or in the end face of a bottle, a tube or attached thereto, the nozzle-bearing adapter various elevations or depressions are formed to snap behind the elements of the cap. For this reason, the outer ends of the spring tongues, which may be formed as fine teeth in the screwed-behind state behind one of the elevations or in each one of the recesses on or in the end face of a nozzle supporting adapter engaged. As a result, you can not unscrew the cap to the left.
