EP0631739A1 - Adhesive stick and its process of manufacture - Google Patents

Abstract

The invention relates to an adhesive stick, having a piston which supports the stick substance and having a sleeve which surrounds the stick substance, in which the drive device for moving the stick substance upwards and downwards is designed in the form of a connecting rod which is linked to the piston and is linked at the other end to an actuating element which can be actuated outside the sleeve. The drive element can be designed as a rod (2, 18A, 30, 40, 52) or as a flexible band (2C). The actuating element can be designed as a double ring (3), as a knee joint (17), as a tongue-shaped double wheel (32), as a wheel (41) or as an at least semicircular solid wheel (53). According to a preferred embodiment, the drive element, together with the linked piston and the actuating element, is designed as a one-piece injection moulding which is inserted in the sleeve from the open side for the assembly of the adhesive stick, whereupon the adhesive stick substance is poured into the hollow space in the sleeve from above and is anchored on or in the piston while it solidifies. <IMAGE>

Description

In the production of glue sticks of the previously common type, which have a rotatable foot part with a rotating spindle which engages in a holding device for the stick mass, which e.g. is in the form of an anchoring plate, a piston or a basket, the holding device being firmly fitted into an outer shell which protects the pin mass from drying out and from damage, difficulties have arisen in the quick assembly before the pins are filled.

The outer sleeve, the holding device and the foot part with rotating spindle are manufactured separately and then assembled. The rotating spindle must be rotated quickly and very precisely for assembly through a central recess in the holding device which was previously inserted into the outer sleeve, while at the same time the lower edge of the outer sleeve engages with the foot part.

Since considerable forces occur in this case, the reject of damaged holding devices and damaged rotating spindles is not negligible for economic reasons, in particular also from the additional point of view of the reuse of rejects.

Furthermore, when using such telescopic pens, it has been shown that the rotating spindle engaging in the core of the pen mass reduces the volume of adhesive available due to the space required for it.

The pitch of the pin is also determined by the slope the spindle is limited, ie the greater the advance length desired by the consumer, the greater the number of spindle rotations required for this.

With regard to the mechanism of the lifting movement, it would also be desirable to get away from the rotary movement which is transmitted to a double-turn spindle.

The object of the invention was therefore to solve the above-mentioned problem of assembly and the problems of the drive mechanism.

The solution principle according to the invention is based on the idea of realizing the upward and downward movement of the pin by means of a drive element acting as a connecting rod, which is articulated at one end to a holding device (piston) for the pin mass and at the other end to an actuatable outside the sleeve Actuator is articulated.

According to an embodiment of this invention, the drive element is designed as a rod which is articulated at one end to the bottom of the piston and at the other end is connected via a joint to an actuating element designed as a double ring, which is arranged in two at the lower end of the sleeve opposite slots engages, a stop being provided on the circumference of the double ring.

The double ring, together with the double articulated rod and the piston acting as a holding device, is very expediently designed as a one-piece injection molding.

The sleeve with the opposing slots is also designed as a one-piece injection molding, both molded parts being made from the same plastic, such as polypropylene can be, which facilitates the disposal of rejects and waste.

The assembly is achieved in that the injection molding, which comprises the flexible double acting as an actuating element, the double articulated rod and the piston, can be inserted directly from above into the slotted sleeve and thereby snaps into the slots.

The principle of the connecting rod drive also enables e.g. elliptical cross-sectional shapes of the outer sleeve, which has the advantage that the deformation of the double ring during insertion into the sleeve is less. In addition, the ring then protrudes less far beyond the edge of the sleeve.

The elliptical pen shape also has the advantage for the user that he can produce either a thin or a wide adhesive strip depending on the posture of the pen.

The required diameter of the double ring depends on the desired lifting height of the pin, i.e. on the length of the glue stick in question.

• Fig. 2 zeigt eine Draufsicht A-A und
• Fig. 3 erläutert mehr im Detail die Art der Rücklaufsperre für den Betätigungsring.

This embodiment is explained in more detail with reference to Figures 1 to 3:

• 1 shows a section A-A through the fully assembled pin,
• Fig. 2 shows a top view AA and
• Fig. 3 explains in more detail the type of backstop for the actuating ring.

The piston (1) has an anchoring element (7) for the adhesive compound and a sealing lip (4). The rod (2) acting as a connecting rod, which is connected at its opposite end via a joint (2B) to the double wheel (3) acting as the drive element, is preferably articulated centrally on the piston. The double wheel (3) has a stop (9) on its circumference in the apex of the starting position, so that it can only be actuated in the direction of the arrow. The double wheel (3) also has stabilizing spokes (6). It engages in the slots (5A, 5B) of the outer sleeve (5), which has a cap closure at its open end, which protects the pin mass from drying out and is preferably designed as a plug cap (10).

The double ring (3) is provided with a transverse corrugation (8) on its circumference, whereby the notches formed thereby act as a backstop, since the upper edge of the two recesses (5A, 5B) engages in the initially lying notch, as in FIG. 3 is shown in section Y.

The anchoring element (7) of the piston (1) is very expediently designed as a type of basket with cams and / or retaining grooves (7A), since this ensures good anchoring of the filled-in pin mass after it has cooled and solidified.

Fig. 2 shows the section A-A on an elliptical shaped pin, in which the opposing slots (5A, 5B) are advantageously located at the location of the largest diameter of the ellipse. With a broken line, the section of a pen with a circular cross section is shown in FIG.

According to a further preferred embodiment, the drive element is designed as a flexible band which is articulated at one end to the bottom of the piston and is articulated at the other end in a wrap-around arrangement to a double-ring-shaped actuating element which is arranged in two opposite slots arranged at the lower end of the sleeve intervenes.

The double ring, together with the double hinged flexible band and the piston, is very expediently designed as a one-piece injection molding. In this embodiment too, the injection molding can be inserted into the slotted sleeve during assembly from above or, in another embodiment, from below.

The sleeve can have a circular and preferably an elliptical cross-sectional shape. In the case of an elliptical shape of the sleeve, the advantages already mentioned above result with regard to the particularly easy assembly and to the practical use of the glue stick.

The design of the drive element as a flexible band also has the advantage that the diameter of the double ring does not depend on the necessary piston stroke, so that the ring diameter can be smaller than when the drive element is designed as a rod. In addition, the double ring can also have an axle bearing.

This embodiment is explained in more detail with reference to FIGS. 4 to 9.

• Fig. 6 zeigt eine Draufsicht auf den Stift mit Kolben.
• Fig. 7 erläutert die Rücklaufsperre für den Betätigungsring.
• Fig. 8 zeigt das flexible Band mit Einkerbungen in der Stellung von Fig. 4.
• Fig. 9 zeigt das flexible Band mit Einkerbungen in der Stellung von Fig. 5.

4 and 5 each show a longitudinal section through two embodiments of a fully assembled pin, the flexible band occupying different positions. In the embodiment of Figure 4, the sleeve receiving the drive element is formed in one piece.
In the embodiment of Figure 5, a separate bottom part (5C) is provided, which takes over the tape guide. Here, the one-piece injection molding is usefully inserted into the sleeve from below during assembly and then the bottom part with the band guide is inserted.

• Fig. 6 shows a top view of the pin with piston.
• Fig. 7 explains the backstop for the actuating ring.
• FIG. 8 shows the flexible band with notches in the position of FIG. 4.
• FIG. 9 shows the flexible band with notches in the position of FIG. 5.

The piston (1) in turn has an anchoring element (7) for the adhesive compound, which is preferably designed in the manner of a basket with cams and / or retaining grooves (7A).

The flexible band (2C) is articulated to the piston (1) in an oblique introduction (see FIGS. 5, 2E), which is fastened at the other end so that it can be rolled up on the double ring (3), which fits into the opposing slots (5A, 5B ) the sleeve (5) engages. The double wheel has a transverse corrugation (8) on its circumference, in the notches of which the upper edges of the recesses (5A, 5B) engage, as is shown in detail in section Y in FIG. 7. As a result, a backstop for the actuating element (3) is realized.

When unscrewing the glue stick, the flexible band (2C) is supported on the wall of the sleeve (5), as shown in Fig. 5, whereby it stiffens. The one-sided slitting of the band (2D and 2F) shown in FIGS. 8 and 9 limits excessive buckling of the band if it should turn over, as can be seen from FIGS. 4 and 8. The flexible band therefore stabilizes itself.

The fully assembled and filled pin is closed at the open sleeve end by a cap, which is expediently designed as a plug cap (10).

According to a third embodiment, the drive element is designed as a rod which is articulated at one end to the piston and has a knee joint at its other end, the spoke of which is arranged in a transverse axis provided at the closed sleeve end engages and which knee joint also acts as an actuating element.

In this embodiment, the sleeve is expediently hood-shaped at the closed end and has a gap or slot extending from the apex into which the knee joint engages movably, the sleeve being provided with a screw-on or plug-in closure at the other open end.

The drive element, the actuating element (knee joint) and the piston can expediently be produced in the form of a one-piece injection molding which is inserted into the sleeve from the open end thereof. A link-like insertion aid on the inner wall of the sleeve makes it easier to guide the transverse axis of the drive element in such a way that it reliably engages in the bearing provided in the wall of the sleeve.

Grooves are provided in the knee joint spoke, which engage in knobs on the inner wall of the gap or slot in the sleeve, as a result of which a forward engagement and a backstop is achieved.

The sleeve can be circular or elliptical, the ellipse having the advantages already mentioned above.

The drive element (18) is articulated with one end of the rod (18A) on the piston (1), which is provided with a sealing lip (4) and has an anchoring element (cf. FIGS. 11 and 11a). The rod (18A) merges at its opposite end into a knee joint, the second spoke (17) of which is connected to a transverse axis (16). The rod (18A) and the knee joint spoke (17) have grooves (21), as is illustrated by FIGS. 13a and 13b. The outer edge of the knee joint spoke (17) can have a corrugation which facilitates manual operation.

Fig. 14 illustrates the position and design of the gap (24) in the sleeve (5), in which the drive and actuating element engages, the knobs (22) engaging in the grooves (21) provided there when the knee joint is moved.

15 and 16 explain the function of the guide-like insertion aid (23), which serves to safely guide the transverse axis (16) towards the bearing (25).

After filling the fully assembled device with adhesive, the sleeve (5) is provided at its open end with a screw-on or clip-on closure (26).

According to a fourth embodiment, the drive element is designed as a rod which is articulated at one end to the piston and is articulated at its other end to the tip of a double-sided tongue-shaped double wheel which engages via a transverse axis in a bearing provided on the closed sleeve end and which Dual wheel also serves as an actuating element.

In this embodiment, the sleeve is preferably hood-shaped at the closed end and has a gap extending from the apex, into which the double wheel engages movably, a screw-on or plug-in closure being provided at the open end of the sleeve.

The rod with the articulated piston, the articulated double wheel including its transverse axis expediently form a one-piece injection molding, which in turn is inserted into the sleeve from the open end, a guide-like insertion guide on the inner wall of the sleeve guiding the transverse axis until it engages in the sleeve wall provided bearing takes over.

On the double wheel at least half of the circumference of the same is provided, which facilitates the operation of the wheel by hand and at the same time acts as a backstop by snapping the sleeve edge into the notches of the corrugation. In addition, a stop is provided on the circumference of the double wheel, so that the starting position is fixed after the pen mass has been filled in and rotation is only possible in the direction of the arrow shown in FIG. 17.

The sleeve can be circular or elliptical, the ellipse having the advantages already mentioned above.

This embodiment is explained in more detail with reference to FIGS. 17 to 25:

The drive rod (30) is articulated at one end to the piston (1), which is provided with a sealing lip (4) and has anchoring elements (cf. FIGS. 18 and 18a). At its other end, the drive rod (30) is articulated to the tip (31) of the double wheel (32) which is tongue-shaped on one side and engages with the bearing (34) in the sleeve (5) via the transverse axis (33).

Just as in the third embodiment of FIGS. 10 to 16, a link-like insertion aid (36) on the inner wall of the sleeve (5) serves to guide the transverse axis (33) to the bearing (34) without tilting (see FIGS. 23 and 24).

The double wheel (32) is provided at least over half its circumference with a transverse corrugation (38) which facilitates manual operation and also forms notches into which the sleeve edge can snap, as is shown in detail in FIG. 25, as a result of which a backstop is formed.

A stop (37) is also provided on the circumference of the double wheel, which fixes the starting position of the wheel after the pin has been filled in such a way that rotation is only possible in the direction of the arrow (cf. FIG. 17).

After filling, the open sleeve part is provided with a closure (39).

According to a further embodiment, which largely corresponds to that described above (cf. FIGS. 17 to 25), the actuating wheel is circular and preferably has an axle bearing.

The drive element is in turn designed as a rod which is articulated at one end to the piston and is articulated at its other end to the circumference of an actuating element designed as a wheel, which engages via a transverse axis in a bearing provided at the closed sleeve end.

Since the actuating wheel is preferably axially supported, it does not need to be largely enclosed by the sleeve, which offers advantages for handling the wheel. In addition, it can also be designed as a simple full wheel.

In this embodiment, too, the rod, together with the articulated piston and the articulated wheel including its transverse axis, is advantageously designed as a one-piece injection molding which is inserted into the sleeve from the open end, a guide-like insertion guide on the inner wall of the sleeve guiding the transverse axis to snap into the bearing provided in the sleeve wall. The sleeve has a slot extending from the apex on both sides, into which the wheel engages.

A transverse corrugation is expediently provided on the wheel circumference, which also acts as a backstop, as above has already been described with reference to FIGS. 17 to 25.

In addition, the wheel has a thickening acting as a stop on its circumference, so that the wheel can only be rotated in one direction.

The sleeve itself can have a circular or elliptical shape, preference being given to the elliptical shape.

The drive rod (40) is articulated at one end to the piston (1), which is provided with a sealing lip (4) and has anchoring elements (cf. FIGS. 27 and 27a).

At its other end, the drive rod (40) is articulated on the circumference of the actuating wheel (41), which engages with the bearing (45) in the sleeve (5) via the transverse axis (42).

Just as in the embodiments of FIGS. 10 to 25, a link-like insertion aid (43) on the inner wall of the sleeve (5) serves to guide the transverse axis (42) to the bearing (45) (cf. FIGS. 32 and 33). The sleeve has a slot (44) into which the wheel (41) engages.

The wheel (41) has a transverse corrugation (46), the notches between the corrugations serving as raster elements into which the upper edge of the sleeve (5) can snap, as shown in detail in section 34 in section Y of FIG. 26 is.

The stop (47) is formed by a corresponding thickening on the wheel circumference (see also FIG. 30, which shows a section through the wheel in the center of the axis).

After filling with pen mass, the open sleeve part is provided with a closure (48).

Finally, it is also provided in a further embodiment of the invention to design the actuating element as a non-deformable part or full wheel, which, however, requires a different assembly method.

In this embodiment, the sleeve is formed in two parts, with one sleeve part being closed on one side and having a gap or slit extending from the apex on both sides at the closed end, while the other sleeve part is open on both sides. The two sleeve parts are designed so that they can be completed with each other at an open end.

A rod acting as a drive element is articulated at one end to the solid wheel and at the other end to the piston, the solid wheel having a transverse axis for engagement in a bearing provided in the closed sleeve part.

The combination of rod with articulated piston and articulated full wheel including its transverse axis is advantageously designed as a one-piece injection molding.

Such a molding is first inserted into the bearing in the sleeve part closed on one side until the transverse axis snaps into place, a guide-like insertion guide on the inner wall of the sleeve guides the transverse axis to the bearing.

The sleeve end, which is open on both sides, is then combined with the other sleeve part, for example by a snap or screw connection or by a welded connection.

The full wheel is preferably designed as a shaft wheel and has transverse corrugation on its circumference.

On the inner wall of the slot or the column in the sleeve part closed on one side, knobs are provided which engage in grooves on the drive rod. When designed as a shaft wheel, the knobs also engage in the undulating wheel surface and thereby form a backstop.

In this embodiment too, the cross section of the sleeve can be circular or elliptical.

After filling the fully assembled device with adhesive, the open sleeve end (55C) is closed with a cap (61).
