Description

Technical area

The invention relates to an application pen for dispensing a liquid onto a surface, preferably for applying a protective layer on adhesive surfaces of a vehicle, in particular for adhesion improvement in adhesive applications, comprising a hollow body in which the liquid preferably within an ampoule accommodated in the hollow body, the exit of the Liquid can be broken, is added.

State of the art

Pre-treatment agents for the production of adhesive bonds are usually offered in packages consisting of an aluminum bottle, polyethylene cup and a screw cap of the polypropylene bottle. In the field of disposable applications also aluminum tubes or primer pens and activator pads are offered with low content.

Applikationsstifte the type described above are for example from the WO 2014/004521 A1 known. The WO 2014/004521 A1 describes an applicator pen comprising a cylindrical body in which a glass ampoule is held, an applicator over which liquid can be applied to a surface and a cap. The ampoule is destroyed by a pressure applied radially to the peripheral surface of the application member so that the liquid exits the ampoule. To apply the liquid, the application part comprises a porous body. A seal between the individual parts (cylindrical body, application part and cap) via a press fit ("press fit"). Overall, the application pin gem. WO 2014/004521 A1 the risk of drying the liquid, making this application pen difficult can be used multiple times (over a longer period of time). In addition, the way the ampoule is broken is perceived as being relatively complicated and not very "intuitive".

The invention is therefore based on the object to provide an improved application pen of the generic type, which in particular can be used repeatedly over a longer period of time or to operate in a simple manner.

Disclosure of the invention

This object is achieved in particular by an application pen having the features of claim 1.

In particular, the object is achieved by an application pen for dispensing a liquid onto a surface, preferably for applying a protective layer to adhesive surfaces of a vehicle, in particular for adhesion improvement in adhesive applications, comprising a hollow body for receiving the liquid in particular within an ampoule accommodated in the hollow body (comprising a Peripheral surface), whereby the ampoule can be broken to the outlet of the liquid.

According to a first independent aspect, a breaker having an axially movable portion is provided and formed such that movement of the movable portion in the axial direction results in breakage of the vial. This creates an intuitively easily detectable and simple and effective way of breaking the ampoule. In the prior art, breakers are proposed which require a radial application of force (for example, by bending at a table edge or impressions of a peripheral surface), which is perceived as relatively complicated and complicated. According to the invention, however, can be an axial force (for example, by a blow to one end of the application pen or a rotary drive via a thread, as explained in detail below) comparatively easy breakage of the ampoule can be achieved. An "axial" movement or force is to be understood as meaning a movement or force action in the direction of the longitudinal axis of the application pen.

According to a second, independent aspect (which may preferably be combined with the first aspect), the hollow body has at least two parts, preferably at least three parts, wherein on at least one surface, in particular peripheral surface, of one of the parts of a surface, in particular Peripheral surface, facing another part, a sealing ring, in particular a sealing lip is provided. The sealing ring, in particular the sealing lip is preferably integrally formed on one of the facing surfaces. A "sealing ring" is intended to represent a structure that is self-contained. A "sealing lip" is preferably a "sealing ring", which is designed as a ring lamella. A key idea of the second aspect is to provide at least one sealing ring which simplifies a sealing of the individual components of the application pen. In particular, when the items are movable (such as a cap relative to a head part or a head part relative to a base part, for example, for breaking the ampoule) a high density at the same time allows comparatively simple relative movement.

Overall, more than one sealing ring, for example at least two, preferably at least three or four sealing rings (sealing lips) may be provided on one of the facing surfaces. For example, a plurality of sealing rings (sealing lips) may be provided on an outer circumferential surface of a head part, wherein a first group of sealing rings faces an inner surface of a closure cap and a second group of sealing rings an inner peripheral surface of a base part.

According to a third, independent aspect of the invention (which may preferably be combined with the first and / or second aspect), the hollow body comprises at least one closure cap and a base body which preferably, an end of the application pen facing away from the cap, wherein the closure cap comprises a liquid application part (in particular liquid application felt), wherein the closure cap can be removed together with the liquid application part of the base body, wherein the liquid application part in the removed state of the closure cap to the surface to be applied to the liquid can be applied to apply the liquid. A central idea of the third aspect is that a liquid application part is arranged inside the closure cap and thus the closure cap simultaneously serves as a means for applying the liquid. In the prior art, for example, the WO 2014/004521 A1 the liquid application part remains in the main body of the pen. As a result, when the liquid application part dries, either the entire application pen has to be disposed of or (if this is even possible), the liquid application part has to be removed from the application pen as such, which is associated with a corresponding risk of contamination of the user. In contrast, the invention allows gem. the third aspect, that the cap including the liquid application part is exchanged in its entirety. Since the cap is only a relatively small or easily manufacturable component, this is connected with only a small cost and a low impact on the environment. This generally results in that the application pen can be used several times over a longer period of time.

According to a fourth independent aspect of the invention (which may preferably be combined with the first and / or second and / or third aspect), the hollow body has at least one base body and a head part, wherein the head part comprises a (flexible) end face with a slot , The slot may have a width of at most 1 mm, preferably 0.5 mm, more preferably at most 0.2 mm. Furthermore, the slot may have a length of at least 1.5 mm, preferably at least 2 mm or at most 10 mm, preferably at most 5 mm. A key idea of the fourth aspect is to have a job opportunity according to the "baby bottle principle" show. Furthermore, an optionally transparent cap can be provided. The head part can be made of a (soft) plastic, for example polyolefin (for example polyethylene and / or polypropylene) or of silicone. The head part is preferably designed so that it can be pressed in its front region, so that thereby dosing and application of the liquid can take place. Preferably, the head part has no felt, is designed as "feltless".

In a preferred embodiment, the movable portion is arranged and formed such that it can be moved in the axial direction by a blow carried out in the axial direction on one end of the application pin, so that the ampoule breaks. The "impact" may, for example, be directed to one end of the application pen, which is opposite to the exit region. However, the "impact" is preferably carried out on an end, on which the outlet region is arranged, for example on a closure cap or a head part. By "impact" is meant in particular a preferably short-term, e.g. Less than 0.1 s long, pressurization be understood.

In an alternative development, the movable section can be driven by rotation of a rotatable section, in particular a closure cap, so that rotation of the rotatable section drives the movable section in the axial direction, so that the ampule breaks. The rotatable portion may be formed by the movable portion itself (at least partially). A corresponding rotary drive can be realized for example by a thread (screw thread). When the user then rotates the movable portion (or a rotatable portion of the applicator pin which is operatively connected to the movable portion), it simultaneously drives the movable portion in the axial direction until the ampule breaks, and it is particularly preferred in the context A closure cap can also be removed from the remaining components of the application pen via the same thread, for example the movable section (eg a head part) can be removed with the Closing cap to be connected (in operative connection). About a rotation of the cap, the movable portion can then be moved in the axial direction of the ampoule so that it breaks. After the ampoule has been broken, the closure cap can then be rotated in opposite directions, so that the closure cap can be removed from the remaining components of the application pen. Overall, a simple and feasible without great effort possibility for breaking the ampoule is shown by such measures.

Preferably, the breaking device comprises a deflecting device such that a force which acts axially on account of the movement of the movable section is deflected in the direction of the peripheral surface of the ampoule (for breaking the ampoule). In such an embodiment, on the one hand, a breakage of the ampoule is made possible by an axial movement (for example, an impact from the front or rear) and this is synergistically combined with the fact that by means of the deflection device, a force acting on the peripheral surface of the ampoule is deflected due to the axial movement is, so that the ampoule can be destroyed with relatively little effort.

In a specific embodiment, the breaking device has at least one (preferably flexible) claw, preferably in such a way that at least one claw is driven against the contact surface of the ampoule by the axial movement of the movable section. By such a claw the breaking of the ampoule can be made possible with comparatively little effort, which improves the operability of the application pen.

Preferably, the hollow body comprises a head part and a base body, which comprises an end facing away from the outlet region. The head part is preferably movable relative to the base body in the axial direction. The head part may in this embodiment define the movable portion or at least form part of the movable portion. Farther For example, the head part can form at least one component of the breaker.

In a specific embodiment, the head part is at least partially guided within the base body. In a preferred embodiment, the head part may have the claws described above. The head part (as well as the base body) may be at least partially cylindrical. In particular, when a relative movement between the head part and the base body is used to break the vial (for example, in the presence of an axial impact), the operability of the application pen is improved.

In one embodiment, a head part (in particular the head part described above) can have at least one (porous) liquid absorption body, in particular at least one absorption sponge and / or a liquid application felt for applying the liquid. For example, in this embodiment, a closure cap is removed from the base body and head assembly so that a liquid application felt (especially the liquid application felt) is exposed to the exterior for application of the liquid. The absorption sponge can ensure that vibrations are trapped during transport and thus the ampoule is protected. Furthermore, he can ensure that when breaking the ampoule no glass splinters emerge in the front area. Overall, this makes operability easier and prevents injuries.

Preferably, the hollow body (in particular a base body of the hollow body), at least one run-on slope on an inner peripheral surface in such a way that an axially acting force, at least partially, in a radially inwardly directed (directed to the outer peripheral surface of the ampoule) force is converted. The run-on slope preferably cooperates with the claws described above. These claws can in turn have a corresponding run-on slope. Overall, a preferred embodiment is configured that a run-up slope of a claw cooperates with a run-up slope of the base body such that an axial displacement of the claw in the direction of a rear end of the application pin forces the claw radially inwards so that it presses against the ampule and breaks it. Overall, a structurally simple solution is shown in order to break the ampoule in a safe manner.

In a specific embodiment, a (removable) film element, in particular label, can be arranged around the application pen. The film element may preferably be arranged around a head part and / or between a closure cap and a base body. The film element may be formed so as to block axial movement between the head part and the base body, so that - as long as the film element is attached - the ampoule can not be broken. In a specific application, the film element is then removed, whereby the blockage is lifted by the film element and the ampoule can be broken. If, for example, the film element (label) is labeled accordingly, an intuitive and simple operation of the application pen can be achieved.

In general, the hollow body may have different parts, in particular a base body, preferably comprising an end of the application pin facing away from the outlet area and / or a head part (for example adjacent to the base body) and / or a closure cap.

Within the hollow body, as components of the application pen, a liquid application part (in particular liquid application felt) and / or a sponge (absorption sponge) can be arranged, which prevents glass splinters from passing out of the ampoule.

The liquid application part, in particular the liquid application felt may project at least partially from the closure cap, in particular to at least 2 mm or at least 4 mm. As a result, the liquid application part, in particular the liquid application felt, is easily accessible from outside, so that liquid can be applied to a surface.

The liquid application part may be (optionally fixed and / or integral) connected to the cap, in particular inserted and / or pressed and / or glued and / or welded.

An end of the closure cap facing away from the liquid application part may have a recess. This recess has, for example, a diameter of at least 0.5 cm and / or at most 1 cm and may, for example, have a round cross-section. By such a recess, the cap can be particularly easily grasped, so that the cap can be removed in a simple manner and in particular can act in a simple manner as means for applying the liquid (with integrated liquid application part). This improves operability.

The closure cap may have axially extending ribs on its outer peripheral surface. Also, the operability of the cap, especially when it acts as a liquid applicator (with integrated liquid application part), will be improved.

According to an independent aspect of the invention, a closure cap for an application pen, in particular of the type described above, is proposed, wherein the closure cap has a, in particular porous, liquid application part, preferably a liquid-applied felt.

a section of the embodiment according to Fig. 14 in a schematic section analog Fig. 3 ,

Fig. 1 shows a schematic section of a first embodiment of an application pen. The application pen comprises a base body 10, an (axially movable) head part 11 (which forms a movable section) and a closure cap 12. The base body 10, head part 11 and closure cap 12 define a hollow body 3. The base body 10 has an end 14 facing away from an exit region 13 (rear end) of the application pin. In the hollow body 13, specifically within the base body 10 and (partially) within the head part 11, an ampoule (shown in dashed lines) 15 is arranged. Furthermore, a sponge 16 is provided, which prevents the ampoule (or fragments thereof) from falling out of the application pen. The sponge 16 is provided inside the head part 11. A liquid application felt 17 is gem. Fig. 1 partially disposed within the head portion 11 and the cap 12. Claws 18 (in the present example, four claws are provided, but this number is not mandatory), the ampoule 15 can be broken so that liquid emerges from the ampoule.

The breaking of the ampoule is especially in FIGS. 2 and 3 illustrated. FIGS. 2 and 3 show an enlarged section of the embodiment acc. Fig. 1 in a first position ( Fig. 2 ) and a second position ( Fig. 3 ). In Fig. 2 It can be seen that a stop 19 of the head part 11 is removed from a stop 20 of the base body 10, so that the head part 11 and base body 10 can be moved towards each other, which is symbolized by the arrows 21. If, in the direction of the arrows 21, a blow is then exerted on an end 22 of the application body, which is assigned to the outlet region 13 and is formed by the closure cap 12 in the present case, the head part 11 shifts incl. Cap 12 in the direction of the base body 10. The final state is in Fig. 3 shown. During this movement, run-up bevels 23 of the claws 18 come into contact with an annular circumferential run-on slope 24 of an inner circumferential surface of the base body, so that the (flexible) claws are bent inward (in the radial direction), so that a pressure is exerted on the ampule and this breaks (s. Fig. 3 ). The impact necessary for breaking the ampoule can be effected, for example, by gripping the base body 10 and pushing the cap 12 face-on against a wall (beaten).

To facilitate that the claws 18 can bend radially inwardly, they are spaced apart by slots 25.

A seal between base body 10 and head part 11 (s. Fig. 3 ) is provided via seal rings 26 provided on an outer peripheral surface of the head portion 11 facing an inner peripheral surface of the base body 10. By this sealing rings 26, a high density is achieved without the mobility between the head part 11 and base body 10, which is necessary for the breaking of the ampoule, would be unduly limited. The cap 12 can be screwed onto the head part 11 via a screw thread 27 (the associated thread of the head part can not be seen in the figure since it is interrupted and the interruptions lie in the cutting plane). A sealing of the closure cap 12 relative to the head part 10 is effected by a cone section 28 on the closure cap 12 and a cone section 29 on the head part 11. Furthermore, the head part 11 has a ring inclined surface 30 which corresponds to the cone section 28 of the closure cap 12. Similarly, the cap 12 includes an annular ramp surface 31 corresponding to the cone portion 29 of the head part 11. Overall, a reliable sealing of the head part 11 relative to the cap 12 is thereby realized.

In Fig. 4 the cap 12 without head part 11 and base body 10 is shown. As Fig. 4 can be removed, the Flüssigkeitsauftragefilz 17 is disposed in a recess 32 of the cap (for example, glued or welded or integrally formed in other ways; if necessary, the liquid application felt 17 can also be detachable from the cap). Thus, if the cap 12 is removed from the other components of the application pen, the cap 12 still has its associated liquid application felt 17, which is soaked due to its previous contact with the sponge 16 with liquid. This liquid in the liquid application felt 17 can then be applied to a surface. If the liquid application felt 17 dried out or for some other reason no longer usable, the cap 12 can be thrown away and replaced by a new cap 12. In this case, the remaining components of the application pen can continue to be used. This considerably increases the service life of the application pen.

Fig. 5 shows a schematic sectional view of a second embodiment of the invention (in a first position). Fig. 6 shows the embodiment according to Fig. 5 without the cap. The ampoule is in FIGS. 5 and 6 for the sake of simplicity not shown, but analog Fig. 1 arranged. The mechanism for breaking the ampoule corresponds to the mechanism according to FIG Fig. 1 to 4 and will not be explained again at this point. In contrast to the embodiment according to the Fig. 1 to 4 is in the embodiment according to the Fig. 5 to 7 no sponge 16 is provided. In the embodiment according to the Fig. 5 to 7 prevents the liquid application felt 17, the glass fragments of the ampoule can escape. For this purpose, the liquid application felt 17 (see. 6 and 7 ) unlike in the embodiment according to FIG Fig. 1 to 4 not integrated in the cap 12, but in the head part 11. Analogous to the embodiment according to FIG Fig. 1 to 4 the head part 11 is sealed off from the base body 10 by sealing rings 26. These sealing rings 26 may be formed as sealing lips or sealing lamellae. Furthermore, an outer circumferential surface of the head part 11, which is opposite to an inner peripheral surface of the cap 12, sealing rings 33 a to 33 c on. The sealing ring 33a (see Fig. 7 ) engages in a corresponding annular recess (groove) 34 on an inner peripheral surface of the cap 12 to form a latching connection. The sealing rings 33b, 33c are as Sealing lips (sealing blades) formed, which further improve the seal. The cap 12 according to the embodiment of the Fig. 5 to 7 is plugged onto the head part 11, wherein a connection is realized by latching.

Fig. 8 shows a schematic sectional view of a third embodiment of the application pen. The third embodiment according to 8 and 9 corresponds to the first embodiment according to the Fig. 1 to 4 (in particular with regard to the sealing between the head part 11 and base body 10 or head part 11 and closure cap 12 and with regard to the liquid application felt 17 and the sponge 16) with the following differences. In the embodiment of the 8 and 9 the ampoule 15 is broken by an annular constriction, which is a predetermined kink. Due to the annular constriction 35 of the base body 10 may be kinked, so that the ampoule 15 breaks. As in Fig. 9 can be seen in the third embodiment is analogous to Fig. 4 the liquid application felt 17 is disposed inside the closure cap 12.

The 10 and 11 show in a schematic sectional view a detail of a fourth embodiment of the invention. The non-illustrated parts of the fourth embodiment, particularly as far as the base body 10 and the mechanism of breakage of the ampoule, may be formed as in the first, second or third embodiment (or a combination of these embodiments). In contrast to the preceding embodiments, in the embodiment according to the 10 and 11 no liquid application felt provided. The falling out of splinters of the ampoule is prevented by the sponge 16, which also absorbs and absorbs liquid. To the application pen according to 10 and 11 To be able to use, first the (preferably transparent) cap 12 must be removed (see Fig. 11 ). By pressing on a peripheral surface 36 of the head portion 11 in the region of the sponge 16 liquid is ejected through a slot 37 according to the "baby bottle principle". The seal between the head part 11 and base body 10 via sealing lips 26, as in the embodiment according to Fig. 1 to 4 , The cap 12 is sealed relative to the head part 11 by means of sealing rings 38a, 38b, wherein the sealing ring 38a engages in a corresponding annular groove 39 on an inner peripheral surface of the cap 12 to form a latching connection. The sealing ring 38b is formed as a protruding sealing lamella.

The FIGS. 12 and 13 show sectional views of a fifth embodiment of the invention ( Fig. 12 with cap; Fig. 13 without cap). The mechanism of breakage of the ampoule corresponds to the mechanism as in the embodiment according to FIG 8 and 9 is described. A sponge is not provided, but a liquid application felt 17. This remains analogous to the embodiment of the FIGS. 5 and 6 in the head part 11, the sealing lips 26 analogous to the previous embodiments, in order to realize a seal between the base body 10 and the head part 11. Furthermore, analogous to the embodiment according to the Fig. 5 to 7 Sealing rings 33 a to 33 c provided to allow a latching of the closure cap 12 and a seal between the closure cap 12 and the head part 11.

In the embodiment according to Fig. 1 to 4 and FIGS. 5 to 7 may be located in a region between the stoppers 19 and 20 (see FIG Fig. 2 ) a circumferential film element (not shown) preferably be arranged as a label. If this label is removed, the stops 19 and 20 can be moved towards each other.

In principle, in all embodiments (possibly with structural adjustments) the respective cap 12 can be screwed onto the head part 11 or plugged on (bounced).

The sponge 16 may for example be a melamine sponge or be made of a different plastic. In general, the sponge 16 may be formed from a foam. The ampoule 15 may for example consist of glass. The base body and / or the head part and / or the closure cap 12 may be made of a plastic, for example Polyamide, polyethylene or polypropylene (generally polyolefin) are formed.

Basically, the application pen is suitable for the application of liquids to surfaces of all kinds. A preferred application is the application of a liquid as an adhesion-promoting substrate or as a protective layer in the region of bonding surfaces (for example in the automotive sector when inserting disks).

The liquid application felt 17 may generally be any liquid application member. The liquid application felt may consist of fibers in random or fluid-oriented fibers.

The FIGS. 14 and 15 each show a section of a sixth embodiment of the application pen. Fig. 14 shows a section analog Fig. 2 , Fig. 15 shows a section analog Fig. 3 , Unlike the embodiment according to FIGS. 2 and 3 For example, the head portion (movable portion) 11 is not moved by an axially acting impact, but by rotation of the cap 12. For this purpose, the cap 12 has a thread 40 (which is preferably formed as an internal thread). The base body 10 has a corresponding thread 41 (which is preferably designed as an external thread), so that the closure cap 12 can be moved by rotation in the direction of the base body 10. As a result, the head part 11 is urged in the direction of the base body 10, so that the run-on slope 23 of the head part 11 analogous to the embodiment of FIGS. 2 and 3 against the run-on slope 24 of the base body 10 starts, so that the claws 18 are pressed inwards and located between the claws 18 ampoule (not in the FIGS. 14 and 15 shown; see. for example Fig. 1 ) breaks. Furthermore, in the embodiment according to FIGS. 14 and 15 Still positioning pin 42 between the liquid application felt 17 and the (in FIGS. 14 and 15 not shown) so that the ampoule can be positioned and supported before it is broken.
