DE4104871A1 - Replenishable coating unit with stopper released by rotation - has internal space under closure in end of shaft into which stopper is fitted and secured - Google Patents

Abstract

The liq. storage insert (32) in a cavity (31) within the enlarged end (1) of a shaft (1) is refilled via an opening (214) in the end closure (21), which is occupied by a tightly fitting stopper (22) when not in use. To release the stopper (22) from the closure (21), both elements are rotated in opposite directions through about 90 deg. For security an axial gap (6) is left between the inner end (213) of the passage through the closure (21) and the storage insert (32). USE/ADVANTAGE - For writing, drawing, signing or marking, an easily handled closure allows liq. replenishment without risk of spillage.

Description

The invention relates to a refillable applicator, in particular a refillable writing, drawing, painting, or marking device according to the preamble of Main claim.

Refillable applicators for liquid writing, Drawing, painting or marking means are known. For example, the DD-PS 48 324 shows a refillable one Fountain pen with felt, the detachable at the end of the barrel Has screw plug. This locking system is for Filling or refilling to handle relatively cumbersome because the screw plug several times with an auxiliary tool must be turned until it can be removed. In addition the locking body is difficult to grasp as long as it is not completely loosened from the thread. Furthermore lies in open state of the memory insert unprotected free, so that he carelessly handling u. U. from the shaft can fall and lead to unpleasant soiling. DD-PS 1 43 387 and FR-PS 5 96 990 are pins or Marking and application devices known Closure body reveal, if necessary, by hand and without Tools are detachable. But here too are the Storage inserts free when open without protection, see above that there is also a significant risk of contamination if these inserts slip out of the shaft or if at upside down or on the inside wall of the device when it is put down Shaft of writing material runs out.

According to US-PS 34 59 484 can on the shaft end screwable end body of a marking device additionally be provided with an adjustable valve in order to be able to regulate the air intake by hand. Whether here Refilling should or should be possible detect. Usually you would do this Unscrew the end cap or the cap, likewise a possibly included memory insert fall out of the shaft and can lead to contamination. In the illustrated  directly filled device is a refill from behind, however anyway only possible without problems if the top of the Device is provided with an outlet valve that the The writing medium inlet channel keeps closed for as long as no axial pressure is exerted on the writing tip.

The object of the invention is therefore a refillable Applicator, preferably one with a memory insert provided writing, drawing, painting or marking device for Filling with a liquid application medium to create which can be refilled easily and without risk of contamination leaves and the closure body is easy to handle.

This task is accomplished with those mentioned in the main claim Features resolved.

Advantageous further developments and preferred Embodiments of the invention are in the subclaims shown.

The invention is explained in more detail below with reference to the drawings explained. Here show:

Fig. 1 shows a first embodiment of the present invention in partial cross-section,

Fig. 2 shows the execution acc. Fig. 1 in side view,

Fig. 3 shows a further embodiment according to the invention in partial cross-section,

Fig. 4 shows the execution acc. Fig. 3 in side view.

The application device shown in FIG. 1 and in FIG. 2 has a shaft ( 1 ), a closure ( 2 ) arranged at the shaft end ( 11 ), a memory ( 3 ) consisting of a storage space ( 31 ) and a storage insert ( 32 ) arranged therein ) and a tip ( 4 ) inserted into the shaft tip ( 12 ) as an application element.

In a closure zone ( 211 ) of the closure body ( 21 ), the closure body ( 22 ) consisting essentially of a closure plate ( 221 ) and a closure extension ( 222 ) is inserted axially until the closure ring ( 223 ) is pressed through the filling opening ( 214 ) was and positively engages on the sealing edge ( 213 ) of the filler neck ( 212 ). It does not matter in which rotational position the two bodies ( 21 and 22 ) are in relation to each other. To facilitate dismantling or opening, it is advantageous if the shape of the shaft ( 1 ) or of the closure body ( 21 ) and / or of the closure body ( 22 ) is selected such that by rotating the two bodies ( 21 and 22 ) against each other, for example 90 °, a mutual position is achieved which enables or facilitates easy detachment of both bodies ( 21 , 22 ) from one another by exerting force axially against one another, thereby causing the reservoir ( 3 ) to be opened for refilling. It is advantageous for this if the shaft ( 1 ) or the closure ( 2 ) has an oval or elongated cross-sectional shape and if the closure body ( 21 ) and the closure body ( 22 ) are connected to one another in such a way that they can be rotated against each other in any connection position . To improve the leak resistance, it is also advantageous if the storage end ( 321 ) and the spacer neck ( 215 ) touch each other, and if the filler neck ( 212 ) is axially shorter than the spacer neck ( 215 ), so that between the two shoulders ( 212 and 215 ) an axial free space ( 6 ) is formed. To avoid contamination when opening the device, the entire axial length of the locking projection ( 222 ) is dimensioned such that the front edge of the locking ring ( 223 ) cannot touch the storage end ( 321 ).

In the application device shown in Fig. 3 and in Fig. 4, the shaft ( 1 ) also has a closure ( 2 ') arranged at the shaft end ( 11 ), a memory consisting of a storage space ( 31 ) and a storage insert ( 32 ) arranged therein ( 3 ) and a tip ( 4 ) inserted into the shaft tip ( 12 ) as an application element.

In a closure region (211) of the closing body (21 ') is essentially of a closure plate (221' used) and a locking shoulder (222 ') existing closure body (22'), said locking shoulder (222 ') the filling port (214 ) of the filling attachment ( 212 ) liquid-tight and usually also air-tight. Here, the closure body ( 21 ') and the closure body ( 22 ') are hingedly connected to one another by a hinge connection ( 5 ) designed as a film hinge. To facilitate opening, it is advantageous if the shape of the closure plate ( 221 ') or the end body ( 21 ') is selected so that in the closed position always a handle on the closure plate ( 221 ') and / or a recessed grip on the end body ( 21 ') is present in order to be able to lift both parts ( 21 ' and 221 ') against each other on one side, so that a mutual position is reached which fills the memory ( 3 ) or the memory insert ( 32 ) via the memory end ( 321 ) enables. To improve the leak resistance, it is also advantageous here if the storage end ( 321 ) and the spacer neck ( 215 ) touch each other, and if the filler neck ( 212 ) is axially shorter than the spacer neck ( 215 ), so that between the two shoulders ( 212 and 215 ) an axial free space ( 6 ) is formed.

The end body ( 21 , 21 ') should generally be inseparably connected to the shaft ( 1 ), for example welded, glued or fastened by beads. If the shaft tip ( 12 ) and the shaft ( 1 ) consist of at least two parts, which are separate before the initial assembly, and / or if no or a highly compressible memory insert ( 32 ) is used, the closure body ( 21 , 21 ') also be formed or manufactured in one piece with the shaft ( 1 ). For secure closure, a form-fitting snap connection should preferably be provided between the closure body ( 21 , 21 ') and the closure body ( 22 , 22 ') in order to avoid unintentional detachment of the two parts from one another.

In order to ensure that an inserted through the fill opening (214) in the memory (3) or in the storage insert (32) filling cannula the storage insert (32) also touches always approximately centrally or that the liquid to the storage insert (32) When it is reached as centrally as possible, the filling opening ( 214 ) should always be smaller, preferably considerably smaller, than the storage insert ( 32 ) itself.

Applicator devices according to the invention can be refillable Writing, drawing, painting or marking devices with the various order peaks can be used. In particular, ballpoint pens - preferably those which are filled with thin ink, fiber, felt or other wick writing, painting or marking devices, Fountain pens or tube writing instruments with the proposed closures and therefore lightweight refillable.
