Registration of intellectual property rights

Device for mixing at least two components and subsequent suitable positioning -

preferred - and exemplary - for 2-component adhesives.

Inventive idea :

The two components (1,2) of the material are separated from each other in an elastic casing (rubber, plastic). To use it, you only have to overcome the separation (4) and mix the two components together by kneading. The material, which is now ready for use, is then applied to the desired location by opening the casing appropriately.

The elastic cover is disposed of after use.

Advantages of this device are:

1. exact proportioning of the mixing ratios

- it is carried out in industrial production and no longer has to be done by the consumer themselves.

2. Good mixing result

The two components can be kneaded directly by hand. This can be done without worrying about spills etc., as the material is completely coated.

3. Good positioning of the material

The material is available by cutting off a tip (5) of the elastic cover (3). The opening can be made small or large as required. The material can then be applied precisely. The opening is always free and clean as it is intended for single use.

4. Clean and easy work

The mixture no longer has to be prepared by stirring openly. Nothing can go wrong. There is no spatula that could be dirty from previous use. The same applies to the "mixing bowl" that is no longer needed. There is no longer a tube that needs to be closed or opened.

5. Easy availability

The material can be easily carried around in a pea-sized size.

6. Good dosing and economical consumption

Small quantities in particular can be pre-portioned during production. When mixing by hand, however, the mixing ratios become increasingly inaccurate for small quantities. Larger portions than required are not economical. In principle, the device can be portioned for both small and large doses. Unnecessary consumption can thus be largely avoided.

There is no accidental mixing of the components; no more searching for mixing tools (spatulas and trays); no more laborious cleaning of auxiliary tools.

Basically, with a suitable choice of elastic material shell, this new type of mixing, portioning, dosing and positioning technology is suitable for all materials and also consumables/luxury goods; not just the preferred 2-component adhesive. The invention can also be used for powder on the one hand and liquid on the other, etc.

State of the art

In the area of 2-component adhesives, mixing by hand using a small tub and spatula is common. The disadvantages of this are mentioned above.

In addition to the spatula and tub mentioned above, there is a "double syringe" for the appropriate proportioning of the two components - a combination of two syringes as used in medicine - with just one handle. This allows for a fairly reliable proportioning for large quantities. However, experience has shown - particularly for the small quantities that are often required - that uneven quantities are expelled due to unavoidable one-sided pressure.

If mixing ratios other than 1:1 are required, the "double syringe" becomes unfavorable.

In the non-adhesive area, there is the mixing of two components in a closed circuit in light sticks, such as those used by sailors on the open sea. Here, two different chemical liquids are brought into contact with each other by simply bending a stick, so that the fluorescent lighting effect can be created. However, the aim here is not perfect mixing, dosing or proportioning, nor is the mixture used for an outdoor area.

Technical principle

Filling and portioning the elastic tube is done in the traditional way, as is known in the pharmaceutical and food industries (e.g. cod liver oil capsules). What is new is the way the two materials are separated in a casing, which must be able to be opened if necessary without damaging the casing as a whole in order to mix the materials together. For this purpose, a simple turn of 180 degrees, or better 360 degrees or more (twisting), is sufficient to reliably separate the two chambers of the casing from each other.

Another, removable separation within the elastic casing can be achieved by simply gluing or squeezing the ends together, such that increased pressure on the ends of the elastic tube opens the glued area, but not the container. Materials with these properties are available commercially.

In the spirit of a further development of the invention, accidental detachment - and thus unintentional mixing - can be prevented by simply joining the two ends together - for example by melting the plastic at a suitable seam. Only this seam needs to be separated before use.

To open the container, as described above, simply cut it open at a suitable point on the packaging, such as at a corner, as is common with single-use portions of shampoo.

It is advisable to perforate the opening point (5) and/or to provide it with an enlarged contact surface (6) in order to make opening easier. This also facilitates clean work without spilling, which can easily happen when opening jerkily.

In accordance with a further development of the invention, the inner surface of the casing can also be provided with a structure (7) that promotes mixing. (See example in drawing C)

Claims (6)

1. Device for mixing at least two components to be kept separate in a closed casing (3), preferably an elastic casing, with the aim of an application outside the casing, preferably an adhesive application, - for which purpose the device can be suitably opened in order to mix the components together and then put them into use. 2. Device according to 1, characterized in that the separation of the components is achieved by twisting, squeezing or releasably gluing (4). 3. Device according to 2, characterized in that the opening of the closed casing at a provided tear point (5) is facilitated by means of two specially enlarged attack surfaces (6) for easy and clean tearing. 4. Device according to 3, characterized in that the tear point of the opening is prepared by a perforation (5). 5. Device according to 1.-4., characterized in that the mixing of the components is promoted by a favorable structuring (7) of the inner surface of the casing. 6. Device according to 1.-5., characterized in that the separate chambers of the casing are externally connected to one another, whereby an accidental opening of the separation is made more difficult.
