Description

The invention relates to a method for refilling a by brushing a surface of the product-dispensing pen, which consists of a sleeve with an opening at the end with a closed one Bottom into which a pin rotates about its longitudinal axis is embedded, which projects beyond the entire longitudinal axis of the sleeve one side of the bottom as a threaded spindle and beyond the other side the bottom outside of the sleeve designed as a hand-operated knurled nut and a feed element which is secured against rotation in the sleeve via the in a continuous threaded hole of the feed element gripping threaded spindle along the longitudinal axis of the sleeve for dispensing a the sleeve located product mass is displaceable, and if necessary a cover that can be pushed over the upper edge of the sleeve Procedure for refilling the pen to the one for receiving the Product mass free inner volume and the inner configuration of the sleeve adapted, optionally a concentric to the longitudinal axis Bore, preferably a blind bore, having molded body from the Product mass introduced from the opening at the end into the sleeve becomes.

Furthermore, the invention is directed to a refill cartridge for one by brushing a surface of the product-releasing pen, which is a at the end an opening with a closed bottom, in which is embedded in a pin which can be rotated about its longitudinal axis and which is above the entire longitudinal axis of the sleeve protrudes beyond one side of the base as a threaded spindle and beyond the other side of the floor outside of the Sleeve is designed as a manually operable knurled nut, and a feed element, that is secured against rotation in the sleeve over the in one continuous threaded bore of the feed element engaging threaded spindle along the longitudinal axis of the sleeve for dispensing one located in the sleeve Product mass is displaceable, and possibly one over the top Has sleeve edge slide-on cover, and wherein the refill one to the internal volume free for the absorption of the product mass and the inner configuration of the sleeve adapted, optionally a concentric bore formed to the longitudinal axis, preferably a blind bore, having molded body from the product mass.

A large number of brushes are known from the prior art Surface of product-releasing pens, such as deodorant, adhesive, lip, release agent, Shaving soap or colored pencils known, which if necessary with a Cap closable and having at least one end opening Sleeve with therein for dispensing one located in the sleeve, preferably spreadable, product mass along the length of the sleeve axially movable Include pistons. These have the disadvantage that they are usually are not refillable.

For example, the glue sticks known from the prior art must be used thrown away after the adhesive has been used up or has dried out, although the glue stick mechanism after one filling in is usually still fully functional. The well-known pens and glue sticks pose a not inconsiderable environmental impact as plastic waste It must also always in the manufacture of a new pen new (plastic) material are used, which is in addition to the manufacturing costs unfavorably affects the manufacturing price. Finally, too the consumer is forced to buy a completely new pen every time.

A generic method for refilling one by brushing a surface of the product-dispensing pen and a generic refill cartridge are known from GB-A-246,657. Here is a shaving soap dispenser, from which the shaving soap with the help of a spindle-driven Disc can be discharged, with a shaving soap body having a blind bore refillable. To refill the donor the shaving soap molded body having the blind bore over the spindle in the dispenser housing inserted. For glue sticks that have a shaped body from spreadable, soft plastic adhesive mass, is this type of refilling is not suitable because when inserting the Adhesive compound - which is done by hand - there is a risk that the adhesive compound is deformed or even breaks off and then no longer clean and can be inserted exactly into the pen sleeve.

Process for filling lipsticks and corresponding refill cartridges are also from DE-B-1 003 411, FR-A-1.205.370 and US-A-2,753,991 known. Here, the refill body made of lipstick mass at the end of a plunger or socket, and is the lipstick mass otherwise covered by a sleeve. For refilling a lipstick becomes the end piston or the end frame of the refill inserted in the lipstick mechanism located in a pen sleeve and then the shaped body with the plunger into the sleeve of the lipstick retracted, the surrounding the molded body from lipstick masses Supporting sleeve on the front edge of the lipstick sleeve Detached body from lipstick mass. Such refill cartridges are for refilling known glue sticks with screw spindle not suitable because it is a cup-like piston with a closed Reveal floor area in which the screw spindle of the known glue sticks is not insertable, and because such glue sticks none in the Have pin sleeve lowerable sliding mechanism, in which the end Piston or the end version of the refill molded body can be used.

The object of the invention is for a threaded spindle Glue stick a way to refill with product mass too create.

In a method for refilling the type mentioned at the beginning this object according to the invention in that the feed element a cup-like piston and the product mass a spreadable, soft plastic Is adhesive mass, and that to refill the pen first the piston of the pin is removed from the empty sleeve and then a pipe that has a piston at its top detected and at this end with a ring surrounding the piston at a distance Socket is connected, the inside diameter of which is dimensioned such that the sleeve can be pushed over the upper sleeve outer jacket and one has annular stop surface for the side face of the sleeve, with arranged therein, at the end having the piston on the Mounted sleeve and then by pressing the knurled nut Piston with the molded body drawn into the sleeve up to the bottom of the sleeve is, with the pipe with sleeve completely withdrawn from the molded body and finally removed.

In the case of a refill cartridge of the type described in the introduction, the above Object achieved according to the invention in that the feed element a cup-like piston and the product mass a spreadable, soft plastic Adhesive mass is and that the end having the piston Shaped body in a gripping the upper edge of the piston and at this end connected to a sleeve surrounding the piston in a ring at a distance Pipe is arranged, the inner diameter of the sleeve is dimensioned so that the sleeve can be pushed over the upper sleeve outer jacket and one has annular stop surface for the sleeve end face.

In this way, it is not only a safe fixation of the refill cartridge on the pin sleeve, but also and above all centering the tube the refill cartridge and the sleeve. The wall thicknesses of sleeve and pipe do not need to be exactly coordinated.

According to a further development of the invention, the sleeve is preferably dimensioned such that that their free end of the sleeve ends with the piston crown or slightly above this. This will see one in the axial direction sufficiently long annular space between the inner sleeve and the Piston outer jacket created.

In a first embodiment, the sleeve and the tube are in one piece formed, in particular manufactured by injection molding, then in the area of the connection point between the pipe and the sleeve radial cross-sectional extension is formed, which is an annular stop surface for the cylinder face.

As an alternative to this, however, it is also possible for the tube and the sleeve to be in two parts to train, the parts being preferably annular Snap or snap connection are connected.

According to a further embodiment of the invention, the piston with the Coupling connected by several webs, when pulling the piston tear off in the direction of the sleeve base, i.e. as predetermined breaking points serve. In this embodiment, the piston and the sleeve as one-piece injection molded part, possibly together with the pipe become. Alternatively, it is possible to use the piston and the sleeve via a detachable when pulling the piston in the direction of the sleeve bottom To connect snap or snap connection to each other, such as that small locking lugs or locking hooks or the like when manufacturing with be injected. These connections also break up after the introduction the threaded spindle from the sleeve during the refilling process.

The invention is therefore based on the basic idea that the user one Pen of the type described above, one for the product reception free internal volume and the internal configuration of the sleeve adapted Shaped body is provided from the spreadable product mass, which pull it into the sleeve of the pin from the opening at the end can. After consumption of the first product filling, the consumer can refill the pen. The consumer no longer needs himself to buy a complete new pen. By reusing the essential, non-wearing parts of a pen is the waste, Usually plastic waste, since the usual pins are made of plastic are reduced. Plastic consumption is also reduced because The manufacturer no longer fills each product together with the whole Pen mechanics containing the pin must sell.

The refilling of a pen is facilitated by the fact that a tube with arranged in it, for the absorption of the respective product mass free interior volume and the interior configuration of the sleeve adapted Shaped body from the spreadable product mass placed on the sleeve and the molded body is drawn into the sleeve. This avoids that when refilling the plastic, especially with glue sticks Part of the product mass peeled off at the front edge of the pen sleeve and thereby the pen becomes dirty.

A comfortable and also a peeling of the soft plastic mass during preventing insertion of the molded body into the existing pin Refilling is further achieved in that a piston provided Shaped body is provided, for which the invention provides that first the piston of the pin from the product-empty sleeve removed and then the molded body having a piston at the end from the spreadable product mass with the piston side into the Sleeve is drawn in.

It can be provided that the shaped body with a concentric Longitudinal axis formed bore, preferably a blind bore is. The fact that when refilling, a molded body with Hole or blind hole is inserted into the sleeve, needs when inserting due to the threaded spindle no or only slight product mass to be displaced, so that there is no volume in the pen or the Pen sleeve must be provided, in which the product mass evade could. There is also no excess volume of product mass emerging from the pen which could contaminate the pen.

To enable easy insertion of the molded body into the sleeve, can create a central blind hole for the threaded spindle along the longitudinal axis of the fitting be provided. This embodiment allows one the tube has the same internal diameter as the sleeve. If not centric Blind hole is provided for the threaded spindle, the tube inner diameter corresponding to that caused by the cutting threaded spindle Diameter increase of the shaped body can be chosen smaller.

It is of course also possible to use a continuous one instead of a blind hole Provide bore along the longitudinal axis of the molded body.

To a pin with threaded spindle conveniently and in relation to any To be able to advantageously refill the risk of contamination is seen by the invention before that a tube with a molded body arranged on the sleeve put on and the molded body is drawn into the sleeve.

It is envisaged that first the piston of the pin will be emptied from the product Removed sleeve and then the end of the piston Shaped body from the spreadable product mass with the piston side placed on the threaded spindle and by actuation the knurled nut of the piston is drawn in with the product mass to the bottom of the sleeve becomes.

A particularly convenient refilling of the pen is possible in that the molded body is surrounded by a tube and provided with a piston at the end is. For this purpose, the invention provides that the piston on its upper Edge caught by the tube is inserted into the sleeve and during retraction the product mass into the sleeve, the tube from the piston and from the molded body completely pushed or pulled and finally removed. in the The main idea here is that the spreadable product mass is filled into a tubular sleeve, the bottom of which Piston is formed such that the piston outer jacket in its upper Part of the sleeve is gripped. Now, for example, the threaded hole of the piston placed on the threaded spindle and by pressing the The knurled nut of the pistons together with the product mass is pulled to the bottom of the sleeve, the tube is pushed continuously from the molded body at the same time so that it can finally be removed. It can be used for sizing of the tube can be advantageous if the end face when screwing down of the piston to the opposite face of the sleeve wall meets.

To facilitate insertion of the refill cartridge into the sleeve of the The invention provides that the shaped body ends in a pin has a through threaded bore piston at its center.

To dry out the product mass on the side facing the piston can prevent the tapped hole by means of the threaded spindle penetrable (thin) skin can be closed, as the invention in Design provides. The threaded bore of the piston preferably has according to a further development of the invention, a single or multiple thread.

The threaded spindle of the pin, like all other parts, is made of inexpensive Plastic, which may have some flexibility having. To insert the spindle tip into the threaded bore of the The invention further provides for facilitating the piston of the refill cartridge before that the piston crown has an inner cone as an insertion aid.

The tube can also be avoided at the end opposite the piston drying of the product mass are closed. For example In this embodiment it is possible for the tube to be cup-shaped prefabricate and the prefabricated cup sleeve with product mass fill before they are sealed with the piston on the open side of the cup becomes.

All that is important when dimensioning the tube is that of the sleeve adapted inner diameter. The pipe wall thickness, however, can in principle can be chosen arbitrarily, however, in order to save material at most be the same size as the sleeve wall.

Likewise, the choice of pipe material is basically optional, provided that the tube is preferably spreadable when the molded body is pulled out Product mass behaves rigidly. Preferably, the pipe is in accordance with Development of the invention made of plastic or paperboard, which is coated can be. The piston, however, should preferably be made of plastic consist.

In order to make it easier to pull out the molded body, the tube or Pipe inner jacket according to the invention is preferably slightly conical formed, the conical taper to the opposite of the piston Forms a cone angle of maximum 3 °.

Furthermore, the refill cartridge is in an embodiment of the invention characterized in that the tube is one of the free sleeve inner height of the pin adapted length and an inner diameter adapted to the inner diameter of the sleeve and has a base designed as a piston for the pin.

As already indicated above, the refill cartridge has a spreadable product mass enveloping tube, the length of which is approximately the free Corresponds to the inner sleeve height of the pin, but it can only be a part the inner sleeve height. The tube has an adapted inner diameter like the pin sleeve, causing the molded body to be pulled in possible in the sleeve interior while stripping the tube becomes. When the refill cartridge is used, the one that is not covered by the tube is covered Part of the piston inserted into the sleeve, so far that at Actuation of the knurled nut into the threaded hole of the Kolbens takes hold. When the knurled nut is turned further, the piston will move and pulled towards the bottom of the sleeve, with the threaded spindle tip after passing through the threaded hole in the molded body with simultaneous "Cutting" a thread equally in the product mass Pulls in the cylinder. The rotation of the knurled nut continues until until the piston has reached the bottom of the sleeve. Is in this position the molded body has been completely pulled out of the tube so that this can be removed. The refilled pen can now how known in the art, with a cap at the open sleeve end be closed. The refill can be done as often as you like repeat as the plastic parts when the knurled nut is actuated - both when expelling the product and when refilling - none are subject to significant wear.

To prevent when inserting the refill cartridge into the pen sleeve Air is trapped in the pen sleeve, the invention excels according to further training finally characterized in that the molded body on his Has a longitudinal groove or notch on the outer circumference.

The example below is for a glue stick, in which the product mass 23 made of spreadable, soft plastic adhesive mass consists.

The cylindrical shaped body 2 shown in Figure 1 consists of soft plastic spreadable adhesive mass 23. The molded body 2 is in its three-dimensional extent so that for the adhesive absorption free internal volume and the internal configuration of the sleeve of a glue stick adjusted that he in the direction of arrow 3 in the sleeve of the glue stick insert and fully retract into the sleeve. An example for Such a pin is described below with reference to Figures 5 and 6. In the simplest form, it is a smooth surface cylindrical shaped body 2.

FIG. 2 shows a top view of a cylindrical shaped body 2, the is provided on its outer circumference with a longitudinal groove or notch 4. Along this notch 4 can be when inserting the molded body 2 into the sleeve of a glue stick, escape air from inside the glue stick sleeve.

FIG. 3 shows a shaped body 2 made of spreadable adhesive composition 23, which is provided with a piston at the end. Figure 3 shows the molded body 2 still in the partially shown mold 6 immediately after Pour the adhesive mass, which is still liquid during manufacture 23 and their solidification. The piston is cup-shaped with a total cylindrical elevation 7 formed in its center. On the inside of the piston and the outside of the cylindrical elevation 7 are annular collar 8 and 9 shaped. This collar cause secure anchoring of the adhesive mass 23 in the cup-shaped piston and prevent the soft plastic adhesive compound from tearing off or shearing off 23 when inserting the molded body 2 into the sleeve of an adhesive stick.

FIG. 4 shows a molded body 2 as a further exemplary embodiment spreadable adhesive mass 23 at the end one in its center Continuous threaded bore 10 having piston 11. The piston 11 is cup-shaped and on its inside with a provided on the inside with a collar 12 protruding in a ring shape. Concentric to its longitudinal axis is one in this shaped body 2 Blind bore 13 formed.

The moldings shown in Figures 1 to 4 are not shown in Wrapped in the longitudinal direction by a tube, as follows to the embodiment of the refill cartridge le is described.

The glue stick 14 shown in FIGS. 5 and 6 is in principle after known in the art. It consists of a sleeve 15 with a closed bottom 16, in the by means of a snap connection, not shown a pin rotatable about its longitudinal axis is embedded, which extends beyond the entire longitudinal axis of the sleeve beyond one side of the Snap connection as threaded spindle 17 and beyond the other side of the Snap connection outside the sleeve 15 as a hand-operated knurled nut 18 is formed. In the sleeve 15 there is a piston along its longitudinal axis 19 slidably arranged over the threaded spindle 17. Because in the figures 5 and 6 each molded body 2 with piston 19 and tube 22nd are shown, which is usually slid over the upper edge of the sleeve Cover cap not shown. This is by means of snap connections 20 or threaded or snap connections releasable on the sleeve outer jacket to fix.

The piston 19 has a continuous threaded bore 21 on its bottom, wherein the threaded spindle 17 can engage. The piston 19 forms the bottom part a refill cartridge, which otherwise consists of a tube 22, whose lower edge area encompasses and encompasses the upper piston edge. The top Tube end 22a (Fig. 6) can be closed so that the spreadable Adhesive compound 23 does not dry out. The piston crown can also be a have penetrable skin 24 (Fig. 6) which closes the threaded bore 21. A piston crown 25 is used as an insertion aid has the piston 19 on its outer jacket in the longitudinal axial direction groove-shaped depressions 26 widening triangularly toward the underside of the piston on that cooperating with corresponding ribs 32 of the sleeve inner shell prevent rotation of the piston 19 when the knurled nut 18 is actuated.

An embodiment of a refill cartridge le shows the Figure 7, which is essentially the training and use of a Sleeves 27 distinguished. This sleeve 27, like the tube 22, is cylindrical executed and for example via an annular snap connection 28 connected to the tube 22. This sleeve 27 has an inner diameter 29, which is dimensioned so that the sleeve 27 on the outer jacket the sleeve 15 (see Figure 5, 6) can be pushed on. The sleeve 15 slides into the annular cavity 30 between the sleeve 27 and the plunger 19, the refill cartridge le with respect to the glue stick 14 is securely fixed and centered.

In the present case, the sleeve 27 is so far over the sleeve 15 pushed until the end face 15a (see Figure 5) and the annular Place stop face 27a together.

However, the sleeve 27 can also be designed as a one-piece body with the tube 22 be, then in the area of the junction between Pipe 22 and sleeve 27 an inner radial cross-sectional expansion Formation of an annular end face analogous to the stop face 27a is present.

The piston 19 is connected to the sleeve 27 via radial webs 31, the during the refilling process, i.e. when the piston 19 in the direction of Sleeve bottom 16 is moved, tear off, whereby the piston of the sleeve 27th is solved. In particular in the embodiment in which the tube 22 and the sleeve 27 are formed in one piece, the piston 19 can also have a Detachable snap or snap connection with the one-piece piece mentioned 22, 27 may be connected. All parts can consist of injection molded parts, which, insofar as they should be in one piece or connected to one another, also in can be produced in one operation.

Of course, the cross-sectional geometry of the refill cartridge 1e to adapt that of the sleeve 15 of the glue stick 14, for example the glue stick could also deviate from the tubular cylinder shape and be multi-rectangular his.

The diameter of the blind bore 13 is preferably such that that the threaded spindle 17 only slightly when entering the blind bore 13 cuts into the adhesive mass 23, so that a radial expansion of the molded body 2 and a displacement of the adhesive mass 23 at Insertion into the sleeve 15 is largely avoided.

The refill cartridge 1e can in the usual way in foils, paper or combinations be packed out of these. For example, B. also sealed edge bags, Thermoformed parts, wood pulp or starch derivative molded parts. It several refill cartridges can also be packed in one package, from which individual refill cartridges, for example by tearing or Cancel can be removed or removed individually.

It is also possible to mold 6 before filling the adhesive mass 23 to be lined with packaging material such as plastic film. The packaging material then acts as a separation aid. This will be done before Potting the adhesive mass 23 and the setting of pistons 11, 19 and Tube 22 with sleeve 27 introduced into the mold 6 the packaging material, preferably such that it is close to the inner surfaces of the Cast mold is present.

To refill glue sticks, first the respective refill cartridge surrounding packaging completely or partially removed.

A sleeve end of the refill cartridge 1e that is free of the packaging becomes placed on the end opening of a glue stick sleeve 15 and then the molded body 2 is drawn into the sleeve 15. Here will the refill cartridge le with the piston 19 first into the sleeve 15 slightly inserted until the threaded spindle tip 17a with the thread of the threaded spindle 17 engages in the threaded bore 21. With continuous operation the knurled nut 18, the piston 19 is then pulled down until the annular stop surface 27a on the opposite end face 15a of the sleeve 15 abuts. With further rotation of the threaded spindle 17 through Rotation of the knurled nut 18, the piston 19 is continuously down pulled, with the threaded spindle 17 in the adhesive compound 23 cuts a thread and pulls the molded body 2 evenly downwards. The position of the tube 22 relative to the sleeve 15 remains unchanged, so that the material column of adhesive 23 is finally completely out of the tube 22 is removed. Because the pipe length is matched to the sleeve interior height the free adhesive end face is flush with the upper edge of the sleeve 15, so that the tube 22 with sleeve 27 without content can be removed. The glue stick 14 is refilled and can be used again be used.
