Liquid glue dispenser

The invention relates to dispensers or dispensers for liquid adhesives.

Liquid adhesives are usually packaged in aluminum squeeze tubes, from which the adhesive passes through a mouthpiece Squeezing and squeezing the tubes is dispensed. The disadvantage of these tubes is that they are caused by the accidental application of pressure rupture or rupture easily while the mouthpiece is closed and / or due to fatigue cracking of the aluminum can leak. In addition, it is difficult to handle partially empty tubes cleanly, and these are unsightly too.

The invention is based on the object of creating a dispenser for liquid adhesives which has good performance properties having.

The invention provides a dispenser for liquid adhesives which is rigid, elongated, tubular A container having a dispensing mouthpiece at one end and a flexible section for dispensing adhesive through the Has mouthpiece by manually squeezing this section.

The flexible section preferably has a zone or wall made of elastic or elastically flexible material] which is built in or is designed as part of the container body.

The wall is constructed to be suitable for compression by a finger or thumb / and in a particularly preferred one Embodiment are two diametrically opposite walls in the body of the container for compression placed between a finger and the thumb. The wall can be made of any suitable resilient material, preferably made of a synthetic plastic material.

The wall can be built into the container body so that it is flush with the remainder of the container is arranged, or it can protrude slightly above the container or be slightly recessed into the container be.

In an alternative embodiment, the flexible portion comprises an axially compressible element that is attached to one end of the container is arranged. The compressible one Element is suitably designed in the form of an elastic bellows, which when the compression is released in the initial arrangement can return.

The ratio of the length of the dispenser to its width is suitably greater than 5: 1, preferably 10: 1.

The invention is explained below using an example with reference to the drawing. In this show:

In the embodiment shown in FIG. 1, ^> in Adhesive dispenser a rigid aluminum tube 1, which is attached to a End 2 is closed and has an upper part 5 connected to a mouthpiece 3 via a shoulder 4. The mouthpiece 3, the shoulder 4 and the upper part 5 of the dispenser are formed from a plastic material and with the exception two opposite zones 6 stiff, which are flexible and elastic.

By pressing the two zones 6 together between finger and thumb, a user can apply a controlled amount of adhesive Expel from the dispenser through the mouthpiece 3 for use on a work surface. When solving the The two zones 6 are reset to their original position again under pressure.

Fig. 2 shows a second embodiment of the invention. In this embodiment, the aluminum tube extends 1 to the connection 7 with the shoulder 4 and has two openings 8 through which two raised flexible zones 6 protrude

Fig. 3 shows a further embodiment in which a chamber 9 for expelling adhesive at the closed end 2 of the tube 1 is arranged. In this embodiment, a rigid plastic section 10 has two opposite, elastic, flexible zones 6, which are designed as thinner areas in the plastic molding.

Fig. 4 shows a further embodiment in which the entire tube 1 and the mouthpiece 3 are made of plastic material, with integral flexible, elastic

Zones 6 are designed as thinner areas in the plastic molding.

Fig. 5 shows an alternative embodiment in which the flexible portion for ejecting adhesive elastic, molded plastic bellows 11, which is on closed end 2 of the container 1 is arranged. This embodiment is activated by finger or thumb pressure the end 2 of the bellows 11 is actuated, which, when the manual pressure is released, resiliently returns to the initial configuration is returned.

The dispenser is 10 to 18 cm long and 1 to 2 cm wide, and it is preferably 15 cm long and 1.5 cm wide.

Γ / 's are numerous modifications to the ones described above Embodiments all of which are within the scope of the present invention. There are suitable plastic materials and alternatives to the aluminum tubes, as can be easily seen.

Suitable adhesives for use with the present dispensers include those that have a sufficiently low viscosity to flow through the tube and mouthpiece under manual pressure, e.g. solvent or thinner adhesives .
