Deodorant sticks, adhesive sticks, lipsticks, stripper sticks, shaving soap sticks or color sticks, etc. sticks which release the product upon application to the surface, optionally a cap A holder having an opening at one end, and a plunger designed to be axially movable over the entire length of the holder, housed (fitted) in the holder, preferably There are already many known sticks for applying malleable product blocks. These known sticks generally have the disadvantage that they cannot be refilled.

For example, the adhesive sticks known from the prior art have been used after the initial adhesive filling has been exhausted, or after the adhesive stick has been exhausted, even though the adhesive stick mechanism is generally still fully functional. After the adhesive has dried, it must be discarded. Therefore, known sticks and adhesive sticks are a significant source of environmental pollution as plastic waste. Furthermore, new materials (plastics) must always be used when manufacturing new sticks, which has the adverse effect of increasing production costs, apart from manufacturing costs. And consumers will always buy a brand new stick.

A method of the kind described in the opening paragraph for refilling a stick which releases a product by applying it to a surface and such a refill cartridge is GB-
Known from A-246,657. This document discloses a shaving soap dispenser designed to dispense shaving soap with a spindle driven disk and refill it with a shaving soap stick having blind holes. To refill the dispenser, use a stick for shaving soap with blind holes,
Push it into the dispenser housing with the spindle. This refill method is not suitable for adhesive sticks, including molded pieces of soft, malleable and flexible adhesive mass. The reason is that the product can even be deformed or even broken when pushed by hand and can therefore no longer be cleanly and accurately inserted into the stick holder.

Further, a method for filling lipsticks and corresponding refill cartridges is described in DE-B-1.
003411, FR-A-1205370 and US-
It is known from A-275991. In these cases, the refill of the lipstick mass is provided with a plunger or holder at one end, otherwise the lipstick mass is surrounded by a tube. To refill the lipstick, place the plunger or holder at the end of the refill on the stick
After being inserted into the lipstick mechanism contained within the tube, a plunger pulls the molding into the tube of the lipstick, forming a lipstick mass (supported by the front end of the lipstick tube) The tube surrounding the product is separated from the lipstick mass molding. Such refill cartridges are less suitable for refilling adhesive sticks with known threaded spindles. The reason is that these documents, on the one hand, disclose cup-shaped plungers with a solid bottom into which the threaded spindles of known glue sticks cannot be inserted, such that Such adhesive sticks do not have a feed mechanism that can be pulled down into the stick tube and the holder or plunger at one end of the refill cannot be introduced into the stick tube.

[0007]

SUMMARY OF THE INVENTION The problem to be solved by the invention is to be able to refill an adhesive stick comprising a threaded spindle with a product mass.

[0008]

Means for Solving the Problem In a refilling method of the kind described in the opening paragraph, the means of the present invention for solving the problem is that the plunger is a cup-shaped plunger (19). (23) is a soft, malleable and plastic adhesive, and to refill the stick (14), first the holder (15) not holding the product is moved to the plunger (1) of the stick (14).
9) is removed and then surrounds the upper edge (19a) of the plunger (19), at its end annularly surrounding the plunger (19) at a distance, the sleeve (27) Connected to a sleeve (27) having an inner diameter such that it can be pressed into the upper part of the outer surface of the holder and having an annular inner stop surface (27a) for the front end part (15a) of the holder. The tube (22) with the plunger (1
By mounting on a holder together with a molded product (2) having 9) and rotating a knurled nut (18),
Withdrawing the plunger (19) with the molded product (2) into the holder (15) to the bottom (16) of the holder, and with the sleeve (27) take out the tube (22) from the molded product (2). The feature is that it is finally removed.

Refills of the kind described at the beginning
In a cartridge, the means of the present invention for solving the problem is provided by a plunger (1
9), the product mass (23) is a soft, malleable and plastic adhesive and the upper edge of the plunger (19)
a tube surrounding a), at the end of which:
Surround the plunger (19) in a ring at a distance,
A sleeve (27) having an inner diameter such that the sleeve (27) can be pressed into the upper part of the outer surface of the holder and having an annular inner stop surface (27a) for the front end part (15a) of the holder. Plunger (19) at one end into the tube (22) connected to
A molded product (2) having the above is arranged.

This not only ensures safe mounting of the refill cartridge on the stick holder, but in particular ensures the centering of the tube of the refill cartridge with the holder. Therefore, it is no longer necessary to exactly match the wall thickness of the holder and the tube.

According to another aspect of the invention, the sleeve is preferably dimensioned such that the free end of the sleeve is flush with or slightly overhangs the bottom of the plunger.
In this way, when viewed in the axial direction, an annular space having a sufficient depth is formed between the inner surface of the sleeve and the outer surface of the plunger.

In one embodiment, the sleeve and tube are formed in one piece, in particular by injection moulding, and the cross-section is radially thickened at the sleeve-tube connection to provide an annular stop against the front end of the barrel. Forming a surface.

Alternatively, however, the tube and sleeve can be formed as two parts, which are connected to each other by a snap-in joint, which is preferably annular.

In another aspect of the invention, the plurality of bridges functioning as a site of artificially reduced strength, which is broken when the plunger is retracted toward the bottom of the holder, causes the plunger and sleeve to move together. Can be combined. In this aspect, the plunger and sleeve can be formed as a one-piece injection molded product, optionally with a tube. Alternatively, forming a drop-in or snap-in connection designed to break when the plunger is pulled toward the bottom of the holder, such as forming a small drop-in protrusion or hook during the injection molding process. For example, the plunger and sleeve can be joined together. These connections can also be separated from the sleeve after inserting the threaded spindle in the process of refilling.

The present invention thus fits the internal volume and shape of the holder (designed to accommodate each product mass) and allows the user to pull it through the end opening into the holder of the stick. It starts from the basic concept of providing the user with a molded article of each product mass that is capable of being particularly malleable. After the initial product fill has been used up, the consumer can thus refill the stick. Consumers no longer need to buy entirely new sticks. Because of the reuse of significant non-disposable parts of the stick, the amount of waste, typically plastic, is reduced because the stick is usually made of plastic. It also reduces the consumption of plastics as the producer does not have to distribute each product filled with sticks, including the complete stick mechanism.

In one aspect of the invention, a compliant product mass contained within a tube and conforming to the internal volume (designed to accommodate each product mass) and internal shape of the holder. The tube with the molding is mounted on the holder and the molding is pulled into the holder to facilitate refilling of the stick.
This prevents the sticks from becoming soiled during refilling, especially in the case of adhesive sticks, as the soft, plastic product mass is prevented from parting at the leading edge of the stick holder.

In another aspect of the invention, where the molded article includes a plunger, a convenient refill that does not expose a soft, plastic mass when the molded article is loaded into a stick is provided. You can also get it. To do this, first remove the plunger of the stick from the holder that is not holding the product and then pull the plunger end of the molded article of the malleable product with the plunger at one end into the holder.

The molded article can be formed to have a hole concentric with the major axis, preferably a blind hole. When refilling, the molded product with holes or blind holes is loaded into the holder, so when loading the molded product, the threaded spindle hardly eliminates product lumps, and if any, only slightly. Therefore, in such a case, it is not necessary to provide a space inside the stick or holder in which the product mass can leak (or flow out). In addition, the stick does not become dirty as no excess deposits of product mass flow out of the stick.

For easy insertion of the molded part into the holder, a central blind hole for the threaded spindle can be formed along the axis of the molded part. According to this aspect, the holder and the tube can have the same inner diameter. If the central blind hole for the threaded spindle is not provided, it is necessary to reduce the inner diameter of the tube in response to the increased diameter of the surrounding molding due to the threaded spindle cutting. .

Instead of the blind hole, it is of course also possible to provide a hole that penetrates the entire longitudinal axis of the molded product.

Another aspect of the invention for refilling the stick with a threaded spindle in a convenient and advantageous manner, that is, without the risk of soiling, is another aspect of the present invention, in which a tube having a molding disposed therein is placed over a holder. It is characterized in that it is attached to and the molded product is pulled out into the holder.

First, the plunger of the stick is removed from the holder that is not holding the product, and then the plunger end of the molded article of the malleable product mass with the plunger having a threaded hole at one end is placed on the threaded spindle. And pull the plunger together with the molded product to the bottom of the holder by moving the knurled nut.

When the molded product is surrounded by a tube and a plunger is provided at one end, a particularly convenient refill of the stick becomes possible. Therefore, another aspect of the invention is to introduce the plunger into a holder whose upper edge is surrounded by a tube,
It is characterized in that when the product mass is pulled into the holder, the plunger and the molding are pushed or pulled completely out of the tube and finally removed. Basically, the malleable product mass is filled into a tubular holder whose bottom is formed by the plunger, with the outer surface of the plunger being surrounded by the holder at its upper end. For example, when screwing a plunger screw hole onto a threaded spindle and when pulling the plunger with the product mass to the bottom of the holder by rotating the knurled nut, the tube is continuous from the molding at the same time. Be pulled out and eventually removed. The tube is advantageously dimensioned such that the front end portion of the tube abuts the opposite end of the holder wall when the plunger is pulled down by the screw action.

To facilitate insertion of the refill cartridge into the stick holder, another aspect of the invention is to mold a plunger with a central threaded hole therethrough at its end. The feature is that the product has.

In order to prevent the product mass from drying out on the side facing the plunger, the screw holes can be closed by a (thin) membrane designed to be broken by a threaded spindle. In another aspect of the invention,
The threaded holes in the plunger preferably have single or multiple threads.

Like the other members, the threaded spindle of the stick is made of less expensive plastic, possibly with some flexibility. For easy introduction of the spindle end into the plastic threaded hole of the refill cartridge, the inside of the bottom of the plunger can be conically shaped to act as an insertion aid.

The tube may be sealed at the opposite end of the plunger to prevent the product mass from drying out. For example, in this embodiment, the tube can be preformed in the form of a cup, or the cup can be filled with a mass of product prior to closing the open side of the thus preformed cup with a plunger.

As far as the dimensions of the tube are concerned, the only important factor is the inner diameter which matches the dimensions of the holder. In contrast, the wall thickness of the tube can basically be chosen as required, or in order to save material, it can be approximately equal to the wall thickness of the holder.

Similarly, the tube can be made of a variety of materials, basically provided that it remains rigid when the molded article of preferably malleable product mass is removed. The tube is preferably formed of plastic, coated paperboard, or the like. In contrast, the plunger is preferably made of plastic.

In order to facilitate the removal of the molded part, the tube or the inner surface of the tube is made slightly conical, which has a conical angle of up to 3 ° towards the opposite end of the plunger. It is preferable that

In another aspect of the invention, a refill cartridge comprises a length adapted to the free inner holder height of the stick, an inner diameter adapted to the inner diameter of the holder, and a bottom portion which functions as the plunger of the stick.
The tube has a feature.

As mentioned above, the refill cartridge comprises a tube surrounding a malleable product mass, the length of which substantially corresponds to the free internal height of the stick tube, but the stick holder. May be a fraction of the internal height of. The tube has an applied inner diameter as in the case of a stick holder, so that the molding can be drawn into the interior of the mounting while simultaneously removing the tube. When using a refill cartridge, place the portion of the plunger that is not covered by the tube of the plunger inside the holder to the extent that the threaded spindle engages the threaded hole in the plunger as you rotate the knurled nut. To insert. As the knurled nut is further rotated, the plunger is gradually pulled toward the bottom of the holder, and the tip of the threaded spindle passes through the threaded hole in the molded product before "cutting" the screw. At the same time, similarly pull the product mass into the cylinder. The rotation of the knurled nut is continued until the plunger reaches the bottom of the holder. In this state, the molded product is completely pulled out of the tube, so that the tube can be removed. The refilled stick can be sealed at the open end of the holder with a sealing cap, as is known in the art. Apply the product by rotating the knurled nut,
The refilling process can be repeated semi-permanently, since the plastic part is not subject to significant wear when refilling the holder.

In order to prevent air from being trapped in the stick holder when the refill cartridge is loaded into the holder, in another aspect of the invention, the outer peripheral portion of the molding is longitudinally aligned. It is characterized by providing a groove or notch.

DETAILED DESCRIPTION OF THE INVENTION Referring to the accompanying drawings,
The present invention will be described in more detail. FIG. 1 is a side view of a molded product. FIG. 2 is a plan view of another embodiment of the molded product. FIG. 3 shows another embodiment of the molded product with a part of the mold. FIG. 4 shows another example of the molded product.
5 and 6 are side views and partial cross-sections, respectively, of an adhesive stick to which a molded product according to another embodiment is attached. FIG. 7 is a side view / side sectional view of the refill cartridge of the present invention.

The example described below relates to an adhesive stick, and the product block 23 is a soft, malleable and plastic adhesive.

The cylindrical molded product 2 shown in FIG. 1 is formed of an adhesive mass 23 which is soft and has plasticity and spreadability. In a three-dimensional configuration, the molding 2 fits within the holder's internal volume (designed to fit the adhesive mass) and internal shape so that the molding 2 fits inside the holder of the adhesive stick. Can be introduced in the direction of the arrow 3 and pulled completely into the holder. An example of such a stick is described below with reference to FIGS. In its simplest form, the stick is a smooth surfaced cylindrical molding 2.

FIG. 2 shows a longitudinal groove or notch 4 on the outer periphery.
FIG. 3 is a plan view of a cylindrical molded product 2 provided with. When the molded product 2 is loaded into the holder, air can escape from the inside of the adhesive stick holder to the outside along the groove 4.

FIG. 3 shows a molded article 2 of a malleable adhesive mass 23 having a plunger at one end. Figure 3
Shows the molded part 2 still in the mold 6 (partially shown) immediately after the injection of the adhesive mass 23, but the adhesive mass remains liquid during the manufacturing process and during curing. The plunger has a cylindrical projection 7 in the center and is generally cup-shaped. On the inner side of the plunger and the outer side of the cylindrical protrusion 7, annularly projecting collars 8 and 9 are provided. These collars firmly anchor the adhesive block 23 in the cup-shaped plunger securely so that the adhesive block 23 may tear when the molded product 2 is loaded into the holder of the adhesive stick. , To prevent shearing.

FIG. 4 shows another embodiment of the molded article 2 of the spreadable adhesive mass 23, which has at one end a plunger 11 having a screw hole 10 penetrating the entire length of the plunger 11 in the central portion. Is shown. Plunger 11
Has a cup shape and is provided with a collar 12 projecting annularly on the inside. The molded product 2 is provided with concentric blind holes 13 in the longitudinal direction.

The molded products shown in FIGS. 1 to 4 are as follows.
As described with reference to the exemplary embodiment of the refill cartridge 1e, it can be longitudinally enclosed by a tube (not shown).

Adhesive stick 14 shown in FIGS. 5 and 6.
Are known in principle from the prior art. It consists of a holder 15 with a closed bottom 16 on which the stick is mounted for rotation about its longitudinal axis by means of snap-in joints (not shown). The stick extends over the entire long axis of the holder and is provided with a threaded spindle 17 on one side of the snap-in joint and on the outside of the holder 15 on the other side of the snap-in joint. There is a knurled nut 18 which is manually operated. The plunger 19 is mounted for movement in the length direction of the holder 15 by means of a threaded spindle 17 means. 5 and 6, the plunger 1
Since the molded article 2 is shown mounted using 9 and the tube 22, a sealing cap, which is usually designed to be pressed onto the upper edge of the holder, is not shown. this is,
It can be removably attached to the outside of the holder by a drop-in connection 20 or thread or snap-in joint means.

At the bottom, the plunger 19 is provided with a threaded hole 21 designed to engage the threaded spindle 17. The plunger 19 forms the bottom of the refill cartridge 1d, otherwise the refill cartridge consists of a tube 22 whose lower rim occludes and / or surrounds the upper edge of the plunger. The upper end 22a of the tube can be closed to prevent the spreadable adhesive mass 23 from drying out (FIG. 6). Further, the bottom of the plunger may have a rupturable membrane 24 that closes the screw hole 21 (FIG. 6). A cone (conical portion) 25 provided inside the plunger bottom portion functions as an insertion aid. Further, the outer surface of the plunger 19 is provided with a groove-shaped recess 26 that expands in a triangular shape downwardly of the plunger along the long axis direction, which is formed by a rib 32 on the inner surface of the holder. Together, they prevent rotation of the plunger 19 when turning the knurled nut 18.

An embodiment of the refill cartridge 1e of the present invention is shown in FIG. 7, which embodiment is largely identified by the use of the sleeve 27 and the resulting improvements. Like the tube 22, the sleeve 27 has a cylindrical shape and is connected to the tube 22 by, for example, an annular snap-in joint 28. The sleeve 27 has an inner diameter 29 that allows it to be pressed onto the outside of the holder 15 (see FIGS. 5 and 6). Holder 1
5 is slidably inserted into the annular space 30 between the sleeve 27 and the plunger 19 to ensure the refill cartridge 1e is mounted and centered with the adhesive stick 14. You can

In this case, the sleeve 27 is pushed into the holder 15 until the annular stopper surface 27a and the surface 15a of the holder 15 come into contact with each other (see FIG. 5).

The sleeve 27 may be formed integrally with the tube 22, but in this case, the stop surface 27a is formed near the connecting portion between the tube 22 and the sleeve 27.
While increasing the thickness of the inner radial cross section while forming an annular surface similar to.

The plunger 19 is connected to the sleeve 27 by means of a radially extending bridge 31, but it breaks during refill installation, ie when the plunger 19 moves towards the bottom 16 of the holder, so that It can be separated from the sleeve 27. Particularly, in a mode in which the tube 22 and the sleeve 27 are formed as an integral part, the plunger 19 is detachable.
It can be connected to the above-mentioned integrally molded part 22, 27 by an in or snap-in connection. All parts can be injection molded, or even manufactured in one step if all parts are one piece or connectable to each other.

The cross-sectional shape of the refill cartridge 1e is, of course, the holder 15 of the adhesive stick 14.
It is also possible to adapt the adhesive stick to a polygonal shape instead of a cylindrical shape, for example.

The diameter of the blind hole 13 is preferably such that the threaded spindle 17 bites slightly into the adhesive mass 23 when entering the blind hole 13, and therefore the adhesive mass 23 is held in the holder 15. It is possible to prevent the molded product 2 from expanding in the radial direction and removing the adhesive block 23, if any, when it is loaded into the container.

The refill cartridge 1e can be packaged in film, paper or film / paper composite in the usual manner. For example, bags with sealed rims, thermoformed parts, groundwood pulp or starch derivatives and the like can be used. It is also possible to house a plurality of refill cartridges in a pack, from which the refill cartridges can be individually removed, for example by breaking or breaking.

Before filling the adhesive mass 23, the packaging material,
The mold 6 can be lined with a plastic film, for example. In this case, the packaging material functions as a separation aid. For that purpose, before the adhesive mass 23 is injected into the mold 6, as well as the plungers 11, 1
Prior to the optional loading of the tube 22 with the 9 and / or sleeve 27, the packaging material is preferably loaded to closely surround the inner surface of the mold.

To refill the adhesive stick, the packaging material surrounding the individual refill cartridges is first completely or partially removed.

After that, the sleeve end of the refill cartridge 1e not having the packaging is applied to the opening portion at the end of the adhesive stick holder 15, and then the molded product 2 is drawn into the holder 15. Insert the plunger 19 of the refill cartridge 1e into the end 1 of the threaded spindle 17
Gently push 7a into holder 15 until it engages screw hole 21. Continued rotation of the knurled nut 18 further pulls the plunger 19 downward until the annular contact surface 27a comes into contact with the opposing front end portion 15a of the holder. When the threaded spindle 17 is further rotated by rotating the knurled nut 18, the plunger 19 is subsequently pulled down, and at the same time, the threaded spindle 17 is cut into the adhesive mass 23 to form a molded product. 2 is pulled evenly downward. The position of the tube 22 with respect to the holder 15 remains unchanged, so that finally the cylinder of adhesive 23 is completely removed from the tube 22. The length of the tube is adapted to the height inside the holder so that the free end side of the adhesive mass can be aligned with the upper edge part of the holder 15 and thus the tube 22 can be completely emptied. . The adhesive stick 14 is refilled and can be used again.
