Description

The invention relates to an applicator and packaging for 2-component material.

For example, with a two-component adhesive, the resin and hardener are mixed using a double syringe and then applied to the bonding area. It is also known to place liquid cyanoacrylate in one chamber and the reaction powder in the other. However, the double syringe used with liquid two-component adhesive is never 100% airtight, so curing occurs even with the packaging closed. This can involve epoxy resin, polyurethane, or methyl methacrylate. Similarly, plastic bottles containing cyanoacrylate or superglue are not 100% airtight, which is why cyanoacrylate cures on its own after some time.

Two-component adhesive, also called two-part epoxy or 2K adhesive, is an adhesive consisting of different components (resin and hardener). Mixing the two components immediately before application usually starts the curing reaction even at room temperature. Two-component systems cure through chemical reactions.
such as polyaddition, polycondensation, and chain polymerization. (from Wikipedia) https://de.wikipedia.org/wiki/Zweikomponentenkleber ).
Typically, the two-component adhesive is first dispensed using a double syringe, then mixed in a mold with a spatula, and finally applied to the surfaces to be bonded using the spatula. Alternatively, a mixing nozzle can be attached to the double syringe to mix the binder and hardener components during dispensing. Both methods are time-consuming and lead to unnecessary waste of adhesive, either due to residue remaining in the mixing nozzle or potential overdosing when used without a nozzle. Furthermore, the single-use components of the double syringe and the syringe itself generate unnecessary costs and a significant amount of plastic waste. Another problem is that the hardener or other reactive component in the tube or syringe will harden spontaneously upon contact with air. This occurs, for example, after initial use and, in the case of unopened double syringes, even before use, via diffusion, as the syringe can never be 100% airtight. This explains the typical shelf life of approximately 12 months.

Cyanoacrylate adhesive hardener is a fine powder that is always used as a reinforcing agent for all types of cyanoacrylates. When applied to the adhesive, it helps to strengthen the bond and increase its durability. The powder can be sprinkled over the adhesive before it cures, allowing it to penetrate any gaps or unevenness and provide additional reinforcement. This is particularly useful when working with porous materials or when extra strength is required for the bond. The cyanoacrylate and the powdered adhesive hardener (https://www.greenstuffworld.com/de/64-cyanoacrylatklebstoff#) are typically sold in separate, resealable bottles or tubes. The problem with this is that the liquid cyanoacrylate in the plastic bottle hardens on its own, especially after initial use. In the case of cyanoacrylate, coated aluminum foil would be used to package the liquid and powder in portions. This way, only the required amount would be used. Another advantage would be that the amount of liquid cyanoacrylate can be precisely adjusted to the amount of powder to achieve a cleaner bonding result and minimize waste.

The invention EP 1 015 352 B1 shows a blister pack for fragile medications, with warnings and handling instructions printed directly onto it to avoid damaging the capsules inside.

The invention EP 12 17 931 B1 describes a liquid in a flexible foil package that can be applied to a surface sequentially and in the desired shape via a breakable closure.

The invention DE 28 44 899 C2 This describes a capsule filled with adhesive that is inserted between surfaces to be bonded. When the surfaces are pressed together, the pressure opens the capsule, releasing the adhesive into the bonding gap.

The invention DE 34 11 253 C2 This describes a capsule containing two different capsules. These are each filled with chemicals that react with each other and harden when mixed. This capsule is used to fill boreholes.

The invention aims to develop an applicator and packaging for two-component materials, thereby solving the problems of handling and precise dosing. It is dissolved in small and minute quantities of 2-component material.

This problem is solved by the features of the first claim. Advantageous embodiments are described in the dependent claims.

The applicator contains two dosing capsules for the respective components, which can be positioned one on top of the other by folding the packaging along a defined crease line. This allows for the simultaneous and precise dosing of both components with a simple manual press, ensuring efficient and user-friendly application.

The dosing capsules are connected by a hinged packaging, ensuring compact storage and safe handling. Once folded, the backs of the capsules lie flat against each other, minimizing the risk of contamination or accidental leakage.

The special arrangement of the dosing capsules in pairs with an intermediate crease line facilitates the targeted and proportionate dispensing of the components by simply folding the packaging along this line.
inie.

Each dosing capsule can be individually manufactured and connected only via the packaging, offering additional flexibility in handling and application. This also ensures that even the smallest dosing capsules can be reliably handled and dispensed.

The orientation of the outlet channels of the dosing capsules can be varied to meet different requirements regarding the application direction and method.

The variability of the physical states of the components (liquid or free-flowing) increases the application range of the applicator for different types of 2-component products.

The specific selection of components such as resin/binder and hardener, or even soap concentrates with fragrances, enables the use of the applicator in a wide variety of areas, from industry to household products.

Different sizes of the dosing capsules after folding ensure that the outlet channels are exactly aligned, enabling precise mixing and application of the components.

The use of blister packaging made of plastic-coated aluminum foil offers a robust and secure packaging solution that simultaneously protects the contents from external influences and prevents the contents from chemically reacting with the aluminum foil.

The capsules' exit openings can be created by simply cutting open the free end of the exit channels, which further simplifies the use of the applicator and allows for direct application without additional tools.

This design gives the applicator a high degree of flexibility and user-friendliness, which is of considerable benefit for a wide range of applications in various industries. The invention promises a precise, clean, and efficient application of two-component products, making it a valuable innovation in this field.

It is also possible to equip the applicator's dosing capsules with a vacuum seal, which would ensure complete separation of the components from the ambient air during storage and before use. This seal would remain intact until immediately before application and would only be broken by a deliberate mechanical action from the user, such as cutting or tearing the vacuum seal. This innovative solution could prevent premature hardening of the materials inside the dosing capsules, thereby increasing the product's shelf life and effectiveness.

After the dosing capsules are activated, the components could be dispensed from the now-open dosing channels. Alternatively, both dosing capsules could have an integrated mixing chamber into which the two components are directed.

This chamber could include an automatic mixing device that would thoroughly mix the components before they were dispensed from the outlet. This arrangement could eliminate the need for external mixing tools and ensure that the components are optimally prepared for application.

To ensure the stability of the components before use, the dosing capsules could be coated with a reaction inhibitor.

This inhibitor would prevent any chemical reaction within the capsules until activation by mechanical pressure. This function would be particularly critical for highly reactive materials that require controlled application.

The modular design of the dosing capsules would allow the user to exchange them as needed and use different types of chemical components. This flexibility would make the applicator suitable for a wide range of applications and user requirements.

The applicator packaging could be made from biodegradable material, allowing for environmentally friendly disposal. This eco-friendly design would contribute to reducing the ecological footprint and appeal to users who value sustainability.

Integrating NFC or RFID technology into the applicator's packaging could allow users to access relevant information such as expiration date, product specifications, and application instructions using a smart device. These smart features could enhance the application's usability and safety.

1 Figure 6 shows a blister pack in which, by way of example, five pairs of capsules P, each consisting of two adjacent capsules 1.1 and 1.2, are connected to each other and via the blister pack 4. Capsule 1.1 contains a first component 1, and capsule 1.2 contains a second component 2. The pairs of capsules P are arranged vertically above one another, enabling compact and efficient storage of the various components. This arrangement protects the capsules P from damage and simplifies the removal of individual pairs of capsules P.

Capsule 1.1 has a circumferential rim area 1R and the second capsule 1.2 also has a circumferential rim area 2R, with which they are connected to each other and included in the blister packaging 6.

For use, a pair of capsules P is separated along the dividing line T, e.g., cut off and then folded along the crease line X. This leaves the two capsules 1.1, 1.2 with their back sides 3 (see 6 ) next to each other, with the packaging material of the blister pack 6 still located between the back sides 3. Now the capsules 1.1 and 1.2 are opened along the opening line A and the components 1, 2 are simultaneously emptied by manually pressing on the capsules and mixed if necessary.

2 Figure 1 shows, for example, five first capsules (1.1) arranged one above the other and connected to each other, next to which five second capsules (1.2) arranged one above the other and connected to each other are placed. Here too, the first capsules 1.1 contain a first component 1 and the second capsules 1.2 contain a second component 2.

The first capsules 1.1 or the capsule strips consisting of the first capsules 1.1 arranged one above the other also have a circumferential rim 1R and the second capsules 1.2 or the capsule strips consisting of the second capsules 1.2 arranged one above the other have a circumferential edge 2R, over which they are each received in the packaging 6.

Both the first and second capsules 1.1, 1.2, which are arranged side by side, are connected to each other exclusively via the packaging 6. This arrangement facilitates the separate handling of each component before mixing and the associated activation.

For use, a capsule pair P is cut along the dividing line from a first capsule 1.1 and a second capsule 1.2 arranged next to it, and folded along the crease line X. As a result, in this variant as well, the two capsules 1.1, 1.2 lie with their back sides 3 facing (see 6 ) one on top of the other, with the packaging material of the blister pack 6 located between the back sides 3. The connection between the two capsules 1.1, 2.1 in the area of the crease line X is only via the packaging material. This makes creasing easier than with the in 1 The depicted variant is possible.

The opening of capsules 1.1, 1.2 in the area of opening line A and the dispensing of components 1, 2 is carried out as in the variant according to 1 .In 3 Another variant is shown in which each capsule 1.1, 1.2, along with its rim area 1R, 2R, is separately contained in packaging 6. The individual capsules 1.1, 1.2 are only connected to each other via packaging 4, which ensures the integrity of each individual capsule 1.1, 1.2 until use and minimizes the risk of cross-contamination.

In this variant as well, for use along the dividing line T, a capsule pair P is cut from a first capsule 1.1 and a second capsule 1.2 arranged next to it, and folded at the fold line X. Only the packaging is located in the area of the fold line X, and also between the back sides 3 (see 6 ) of the two capsules 1.1, 1.2. The connection of the two capsules 1.1, 2.1 in the area of the fold line X is also only made via the packaging material in this variant.

Even in the variant according to 3 The capsules 1.1, 1.2 are opened in the area of opening line A and the components 1, 2 are dispensed as in the variants according to the 1 and 2 .

From the 1 to 3 is evident (but only in the 1 and 2 (requested), that the blister packaging has 6 recesses 6.1 through which the upwardly curved areas of the capsules 1.1, 1.2 protrude.

4 Figure 1 illustrates the folding of two capsules 1.1, 1.2, of a pair (P), each containing a component 1, 2, along a crease line (X). This process allows the capsules (1.1, 1.2) to be positioned so that their contents can be easily mixed and then applied together.

5 shows the top view and 6 The side view of a capsule 1.1 or 1.2. From this, the surface design and the placement of the dosing channels 4 can be seen.

This 5 and 6 illustrate how the capsule(s) 1.1, 1.2 are designed for efficient removal and application and show an exemplary representation of the exit channels 4 and the structural features of the capsule(s) 1.1, 1.2 that are crucial for functionality within the packaging.

The unlabelled height and width of capsules 1.1, 1.2 decrease towards the dosing channel 4.

The back packaging material of the blister pack 4 extends over the flat back 3 of capsules 1.1, 1.2. Furthermore, the material of the blister pack 6 extends over the edge area 1R, 2E, so that the capsules 1.1, 1.2 are securely held within the blister pack 6. The upwardly curved, bulbous area of capsules 1.1, 1.2 and the dosing channel 4 protrude from a respective unlabeled recess in the blister pack 6, which can be seen, for example, from the 1 to 3 as is evident.

To dispense components 1, 2, the dosing channel 4 is opened at its front end at an indicated opening line A, e.g. by cutting it open.

In 7 Figure 6 shows a pair P consisting of a first capsule 1.2 containing a first component 1 and a second capsule 2.2 containing a second component 2, whose dispensing channels 4 point away from each other and which are arranged in a blister pack 6. This arrangement serves to ensure the separation of the components until final application and to prevent interactions between the capsules 1.1 and 1.2.

The capsules 1.1, 1.2 have flat back surfaces 3, behind which at least one rear layer 6b of the blister packaging 6 runs.

At least one front layer 6a of the blister pack 6 extends over the edges 1R, 2R of the capsules 1.1, 1.2, thereby enclosing the capsules 1.1, 1.2 in The packaging 6 is held. The front layer 6a and the rear layer 6b are connected to each other outside the edges 1R, 2R of the capsules 1.1, 1.2.

Alternatively, it is also possible that the edges 1R, 2R are connected to the layers 6a, 6b.

The front layer 6a has a recess 6.1 for each capsule 1.1, 1.2, through which the convex area of each capsule 2.1, 1.2 protrudes.

In packaging 6, the fold line X is located between capsules 1.1 and 2.1.

The fold line X can be perforated.

8 shows the folding of capsules 1.1, 1.2 according to 7 around the fold line X. This process is crucial for the activation and subsequent mixing of the components immediately before application. Folding the capsules brings the dosing channels 4 of capsules 1.1 and 1.2 into a position that enables optimal mixing of the contents.

9 This drawing illustrates the mechanical opening of capsules 1.1 and 1.2 along the opening line (A). The illustration shows how, through a special design, capsules 1.1 and 1.2 are opened along a predefined line (opening line A) to dispense the two components 1 and 2. This process is crucial for the correct mixing and application of the contents, as it enables a precise and controlled release of components 1 and 2 immediately before use.

In 10 The application of preferably manual mechanical pressure D in the direction of the arrow is shown simultaneously to the opposing capsules 1.1 and 1.2. This step is necessary for the effective dispensing of the contents from capsules 1.1 and 1.2. The simultaneous pressure enables uniform and complete emptying of capsules 1.1 and 1.2, ensuring that components 1 and 2 can be efficiently mixed and applied. This visualization clarifies the user interaction with the applicator and demonstrates the importance of correct handling for optimal product function.

These supplementary descriptions to the drawings provide a deeper insight into the functionality of the applicator, particularly with regard to the critical steps of capsule opening and application, which significantly influence the efficiency and effectiveness of the 2-component system.

The capsules 1.1, 1.2 remaining in the packaging during this process can improve their handling when dispensing the two components 1, 2, especially when dealing with small capsule sizes from 0.5ml to 50.0ml.

It is perfectly normal for the lower layer 6b of the packaging to have one or more cutouts.

According to 11 The dividing line T can also run around the dosing channels 4 of the two capsules 1.1, 1.2 in such a way that, after folding, these protrude along the fold line X, so that after opening the opening lines A of the dosing channels, the indicated exit openings 5 also protrude slightly, and thus the components 1. 2 can be applied more precisely.

12 Figure 1 shows the aforementioned capsules 1.1 and 1.2 with the optional inhibition coating I. The inhibition coating suppresses a premature reaction of the filling material in the capsule.
