Description

System for packaging two components

The present invention relates to a system for packaging two components. In particular, the invention relates to a system for two components that are mixed by a user before use.

For various applications, products include two components that must be mixed together by the user before use. For storage and transportation, however, the two components must be stored separately because otherwise the product would undesirably react before use. For example, often two-component adhesives that need to be mixed together just prior to use are packaged in this manner.

In Fig. 1, a previously known product for two liquid components is shown. In this case, the product comprises a first bucket 14, in which the component A is stored. In addition, the product comprises a second bucket 15, in which a second

Component B is stored. Before use, the lids of the buckets 14, 15 are now opened, and the liquid component B is emptied into the first bucket 14 to the liquid component A. Thereafter, the liquid components A and B

typically blended together with a mixer, and the two-component product thus prepared is applied accordingly.

A disadvantage of such known products is that, on the one hand, there is empty space in the first bucket 14, which leads to unnecessarily high storage and transport costs.

On the other hand, it is also disadvantageous that the logistical effort is great because it must always be ensured that for each application an exact number of buckets with the first component and an exact number of buckets with the second component are present.

Furthermore, there is a risk that in one application individual components of different two-component products will be confused if different similar products are in use in the same location. It is therefore an object of the present invention to provide an improved system for packaging two components, which on the one hand allows lower storage and transport costs, and on the other hand, reduces the logistical effort for the packaging of the product. In addition, the improved system should be as simple and user-friendly as possible in the application.

This object is achieved by a system for packaging two components, the system comprising: a first container for receiving a first component; and a lid through which the first container is closable; and a second container for receiving a second component; wherein the second container is disposed on the lid such that the second container is within a volume of the first container when the first container is closed with the lid; and wherein the second container has a predefined opening device, which in the opened state allows a transfer of the second component into the first container.

The solution proposed here offers the advantage that, by integrating the second component in the volume of the first container, a substantial saving in space can be achieved, which leads to significantly lower storage and transport costs. The system proposed here makes it possible to store and transport both components separately and yet store both components in a container in which the components are also mixed together before use.

Another advantage of the system proposed here is that a logistical effort can be greatly reduced: by always packaging both components together, it is automatically ensured that the number of units of the first component and the number of units of the second component are always in the right place Ratio exists.

Providing a predefined opening device on the second container ensures that the system is easy for the user to handle. The user can thus open the second container without great effort or without additional tools to transfer the second component into the first container to the first component. A central idea of the present invention is to make optimum use of the empty space present in the previously known products in the first container under the lid, and at the same time to increase the applicability of the product. A further effect of the system proposed here is that a savings of waste products and packaging waste can be achieved by the more compact arrangement of the components.

The first container may be formed, for example, as a bucket or as a cylindrical container or as a conical container or as a cuboid container or as an irregularly shaped container.

In an exemplary embodiment, the system is configured to package two liquid components.

In an exemplary alternative embodiment, the system is designed for packaging a liquid and a pasty, pellet-like, granular or powdery component. In this case, the system can either be designed so that the liquid component is packaged in the first container, or such that the liquid

Component is packed in the second container.

The components may be, for example, a two-part adhesive or a two-part sealer or a two-part primer.

Specific examples of the components to be packaged by the system are:

A two-part adhesive, especially epoxy based, such as the product sold under the trade name Sikadur® 31;

A two-component sealant, especially based on polyurethane, such as the product available under the trade name Sikafloor® 304;

A two-component primer, especially based on epoxy resin, such as

For example, the product available under the trade name Sikafloor® 156. A ratio of a volume of the second component to the first component may be, for example, between 1: 100 and 1: 1 or between 1:50 and 1: 2 or between 1:20 and 1: 3.

A ratio of the volumes of the second container to a volume of the first container may be, for example, between 1: 100 and 1: 1 or between 1:50 and 1: 2 or between 1:20 and 1: 3.

In an exemplary embodiment, a volume of the first container is between 0.5 dm ³ and 50 dm ³ , preferably between 1 dm ³ and 30 dm ³ , preferably between 1.5 dm ³ and 25 dm ³ , particularly preferably between 2 dm ³ and 20 dm ³ .

The provision of a first container having such a volume offers the advantage that it makes it possible to use the advantages mentioned in particular for two-component building materials (such as, for example, adhesives, primers and sealers), which are typically used in packages with the above-mentioned volumes.

The lid is in particular designed such that the first container is closed fluid-tight with the lid closed. In order to achieve this, the lid may for example be provided with a screw thread, or the lid may close the first container in the manner of a tin can closure.

In an exemplary embodiment, the second container is flexible.

For example, the second container may be configured as a bag.

In an exemplary development, the second container comprises a film for receiving the second component.

The film may have a thickness between 0.1 and 3 mm, preferably between 0.2 and 2 mm, particularly preferably between 0.3 and 1.5 mm. Furthermore, the film may for example be polyethylene or polypropylene or

Polyethylene terephthalate to fas sen.

In addition, the second container may comprise a single film or a film composite.

The provision of a flexible second container has the advantage that on the one hand low manufacturing costs are possible, and on the other hand, such flexible container can be opened very easily to fill the second component in the first Firner before using the product.

In an alternative embodiment, the second container is rigid.

In an exemplary development of the second container is at least partially made of plastic or tinplate or steel.

The provision of a rigid second container offers the advantage that a more robust packaging can be provided thereby.

In an exemplary embodiment, the predefined opening device comprises a predefined location along which the opening device can be cut open or opened or ruptured.

The provision of such a predefined location for opening the second container offers the advantage that thereby a user can open the second container with little effort and without additional tools.

In an exemplary development, the predefined location comprises a tear thread, or the predefined location forms a predetermined breaking point or a predetermined breaking point.

In an exemplary embodiment, the predefined opening device comprises a preformed spout.

The provision of a preformed spout offers the advantage that thereby a transfer of the second component is simplified in the first container. In an exemplary development of the preformed spout beak-shaped or zipfelförmig or conically shaped.

In a further exemplary development, the predefined opening device is arranged on a base of the preformed spout.

It is particularly advantageous to provide the preformed spout at a position of the second container, which is located at a most advantageous Ausgiessposition the second container, for example at a lower end or a lower edge of the second container. Thus, the second component can be conveniently and completely poured into the first container.

In an exemplary embodiment, the second container and the lid are joined together by a fluid-tight seam, wherein the lid closes the second container toward one side, and wherein the lid has a filling device for filling the second container with the second component.

This has the advantage that thereby packaging material can be saved, because the lid also serves as a closure of the first container and as a closure of the second container.

In an exemplary development of the second container and the lid are integrally formed.

In an exemplary development, the filling device with a

Screw closure formed. In an alternative embodiment, the

Filling device welded after filling.

In an alternative exemplary embodiment, the second container forms a fluid-tight sealed volume. This has the advantage that the second container can be filled and sealed before the second container is placed on the lid. Depending on the manufacturing process and product type, this can be advantageous.

In an exemplary embodiment, the second container is prefilled, with a filling of the second container with the second component is provided before an arrangement of the second container on the lid.

In an exemplary embodiment, the system further includes a

Hanging device, through which the lid with the second container can be hung on the first container to leak the second component into the first container.

This has the advantage of simplifying handling of the system.

For example, a user may simultaneously open and run multiple systems without requiring the user to hold the lid with the second container until the second component has completely drained into the first container.

In an exemplary development, the suspension device is designed as a hook.

In a further exemplary development, the suspension device is arranged on the cover or on the second container or on the first container.

For example, the suspension device can be arranged on an inner wall of the first container, or in an alternative embodiment on an outer side of the lid, or in a further alternative embodiment on an underside of the second container.

In an exemplary embodiment, the first container and / or the lid is at least partially made of plastic or tinplate or steel.

Depending on the product used or depending on the components used, another material may be advantageous for the first container or for the lid. In an exemplary embodiment, a handle is arranged on the lid, which is designed to be foldable.

This has the advantage that the lid with the second container by the user easier to handle. The system is still easy to store or stack, because the handle in a folded state hardly takes up additional space.

In a further exemplary embodiment, a handle is arranged on the cover, which is not in the volume of the first container when the first container is closed with the lid.

This has the advantage that it ensures that the handle can not come into contact with the components during transport and storage.

Furthermore, a product is proposed which comprises: a previously described system; and a first component disposed in the first container; and a second component disposed in the second container.
