Description

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.

Furthermore, it is known that 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.

This object is achieved by the metering with the features of claim 1.

Advantageous embodiments of the metering according to the invention are the dependent claims.

Due to the inventive design of a dosing the vorhalte in the pen or container liquid can be well dosed with a low pressure. The groove or slot-like depression in the wall of the receptacle, which extends in the axial direction of the container and in particular can extend from the bottom to a container shoulder, allows the application of the liquid with the low pressure force at the same time good dosing.

According to 1. Fick's law, the diffusion rate from a container is inversely proportional to its wall thickness x. So 5 to 20 g bottles with 1.2 mm HDPE wall thickness and more can only be pressed with more than unreasonable 50 N pressure. By carrying out the slot in the bottle or the metering pin according to the invention can be remedied here.

The goal of a low compressive force and easy metering is achieved in particular by the fact that the slot or a recess from the lower end of the container in particular until shortly before the shoulder or up to her zoom or even the shoulder is formed across. For dosing sticks with a usual capacity for cyanoacrylate adhesive, d. H. from 5 g to 20 g, the slot may have a depth of at least 5 mm, in particular at least 10 mm.

At the shoulder of this container either a nozzle with an outlet opening or a neck with thread or bounce ring can be formed. In general, this first nozzle has an external thread for a special cap. On the thread of a neck, a known nozzle or a dosing head can be screwed. Also, 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.

Furthermore, 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. 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.

If the open lower end is closed by means of a plug, 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 closed or continuous is provided with the continuation of the slot in the container.

Towards 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.

To avoid the formation of stress cracks and to improve the sealing effect of the plug again, it is provided to additionally form 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.

With a plug with a longer sealing sleeve with or without a slot extending therethrough, this open bottom is closed. If you perform the plug without a slot, you laid the elastic, pushable area of the container rather in the middle. At the same time, a nozzle with the outlet opening can be molded onto the upper end of the container.

In order not to unnecessarily reduce the necessary Etikettierfläche, the axial recess is merged into a single gap. On the other hand, 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.

As an additional technique, a rotatable adjusting ring is proposed 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, however, is that the different width cams definitely specify the stroke of the slot, so almost the difference between slot width and Nockenbereite is then the resulting actual stroke. So you can apply cyanoacrylate adhesive or eye drops exactly dropwise, optionally also two or three drops.

To be able to produce the dosing pin according to the invention with such a high degree of deformation at all, a special method is proposed. 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.

So that in this case a deepest possible slot can be realized, which results in a noticeable effect when pressing the container, so easier squeezability is achieved, it was proposed in a slightly different second version, the nozzle with an offset asymmetrically outwards and though away from the slot. With this gimmick you can easily pull the stylus from the nozzle and at the same time realize even with small containers by 3 g and 5 g slit depths of about 5 mm or even about 10 mm and more.

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.

With a plug with a longer sealing sleeve with or without a slot extending therethrough, this open bottom is closed. If one executes the plug without a slot, you put the elastic, printable area of the container rather in the middle. At the same time a nozzle with the outlet opening is formed on the upper end of the container in this case.

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.

So that in this case 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 easily pull out of the nozzle on the one hand and at the same time with small containers by 3 g and 5 g slit depths of about 10 mm and more realize. In this version, a particularly deep slot is possible, which leaves the hard HDPE bottle with wall thickness of more than 1.2 mm pleasantly soft. For the medical sector, easily pressed bottles made of transparent PC, PET, PBT, etc. are possible.

So that one can derive an overpressure in the container during the filling process with adhesive or cosmetics, 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.

• Version A: In der der aufwendigsten Version A ist an der Stirnseite des Universal-Adapters ein Hals mit einem Hals-Gewinde angeformt, auf den eine Steuerhülse mit einer Drehdüse geschraubt ist, die einen Steuerstift abdichtet, wenn die Drehhülse in Richtung Behälter geschraubt ist.
• Version B: In der Version ist eine günstigere Lösung B vorgesehen, bei der direkt und einteilig an die Stirnseite des Adapters eine Steuerhülse mit einem die Austrittsöffnung abdichtenden Steuerstift angeformt ist, auf den eine darauf hin und her drehbare Drehhülse montiert sind.
• Version C: Im Sinne eines modularen Aufbaues trägt der Universal-Adapter in einer Version C einen gleich großen Hals mit einem Hals-Gewinde, auf den eine separate, große Düse geschraubt ist, die vorn selbst eine kleinere Düse mit Gewinde für eine große Kappe besitzt.
• Version D: Der Universal-Adapter trägt in der Version D einen Hals mit einem Hals-Gewinde, wobei der Hals der im Sinne eines einheitlichen Werkzeugaufbaues nach vorn um eine zur Austrittsöffnung hin feiner werdenden Düse einteilig verlängert ist.
• Version E: In der preiswertesten Ausführung E wird an die Stirnseite des Universal-Adapters selbst eine kleinere Düse mit Gewinde für eine kleine Kappe mit Innengewinde angeformt.

In the case of this closed at the bottom with a integrally molded bottom container according to the invention either a thread or a bounce ring are formed on the open, upper end to which a universal adapter is screwed or snapped. The following elements are molded or mounted on this universal adapter:

• Version A: In the most elaborate version A, a neck with a neck thread is formed on the front end of the universal adapter, onto which a control sleeve is screwed with a rotating nozzle which seals a control pin when the rotary sleeve is screwed in the direction of the container.
• Version B: In the version, a more favorable solution B is provided, in which a control sleeve with a control pin sealing the outlet opening is formed directly and integrally on the front side of the adapter, on which a rotary sleeve rotatable back and forth is mounted.
• Version C: In terms of a modular design, the Version C universal adapter has a neck of equal size and a necked thread, onto which is screwed a separate, large nozzle, which itself has a smaller threaded nozzle for a large cap ,
• Version D: The universal adapter in version D carries a neck with a neck thread, wherein the neck is extended in one piece in the sense of a uniform tool structure to the front by a nozzle which becomes finer towards the outlet opening.
• Version E: In the cheapest version E, a smaller nozzle with thread for a small cap with internal thread is formed on the face of the universal adapter itself.

This is a universal, easy-to-dose soft bottle has been created with a universal adapter that is easy to press and dose despite their high wall thickness.

To be able to produce a pin with such a high degree of deformation at all, a special method is proposed: The container of this adhesive and dosing with universal adapter is to be produced purely by injection molding, with a closed bottom at the bottom and with a forward towards widening bounce ring or a thread at the top. In this case, 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.

In a further, specific embodiment of the metering pin according to the invention, the goal of a low compressive 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. In principle, this is a partially wound oval flat bottle, here called the bottle ring.

In order not to unnecessarily reduce the necessary labeling surface, the axial recess is merged into a gap. On the other hand, 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.

In order to be able to produce a bottle with such a high degree of deformation at all, a special method is proposed: The bottle with its recess and the gap is to be produced from a preform in an injection blown process. 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 compactness and stability are proven to be better than with a flat bottle. It saves space in the packaging and on the shelf.

The invention also has a child safety device for superglue bottles or a dosing with child safety to the object. In this case, at a distance and separated by a slot, two mutually offset by 180 ° to each other spring tongues coaxially to a screw cap for sealing the Nozzle of a superglue bottle formed. 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.

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.

When compressing the spring tongues, press their ends or the teeth formed thereon away from the elevations or depressions in an annular clearance in the direction of the nozzle or outwardly into the space therein, during this depression, the cap can be easily after Unscrew left. These two superimposed movements usually do not succeed children.

It is thus possible with this inventive solution to provide the often indicated webs or wings on caps for superglue, which should facilitate unscrewing with some novel features.
