Benefits of technology

[0009] This and other objects of the present invention, which will become apparent hereinafter, are achieved by securing the cap to the clamp with an adhesive. The adhesive can be provided in the interior of the cap so that it fills the space between the cap and the clamp when the cap is put on the clamp. Thereby, due to the adhesive bonding of the surfaces of the cap and the clamp, on one hand, and due to the stability of the adhesive (cohesion), on...

Problems solved by technology

Dependent on the filler material and the physical behavior of the fluid components of the material that fills the bag, leakage can occur at the pigtail end of the bag.
Dependent on a mass that fills the bag, the mass leaving the bag can contaminate the environment.
The drawback of this solution consists in that the adhesion of tape to the surface of the film material cannot always be insured.
The drawback of this solution consists in that the ...

Embodiment Construction

[0018] The closing device 11 according to the present invention is arranged at an end-of a closing section 2 of a flexible or pouch bag 1 that is shown only partially and forms a packaging for a filler material. The bag 1 is formed of a film material. The end-side closing section 2 extends up to a pigtail end 3 that is closed by a clamp 4 which surrounds the pigtail end 3. The free end 5 of the pigtail end 3 is surrounded by a cap 6 that is secured on the clamp 4 with an adhesive 12. The adhesive 12 is a cyanacrylate glue.

[0019] The adhesive 12 is selectively applied, at several points, to the inner surface 7 of the cap 6, and then the cap 6 is pressed over the clamp 4 by being rotated about the pigtail end 3.

[0020] According to an alternative embodiment, the adhesive 12 is applied over the circumference of the outer surface 8 of the clamp 4, and the cap 6 is pressed over the clamp 4 by being rotated about the pigtail end.

[0021] Though the present invention was shown and describe...

Abstract

A device (11) for closing an end-side closing section (2) of a packaging-forming, flexible or pouch bag formed of a film material includes a clamp (4) surrounding the pigtail end (3) of the end-side closing section for closing the same and a cap (6) surrounding free end (5) of the pigtail end (3) and secured on the clamp (4) with an adhesive (12) for forming a force-locking connection between the cap (6) and the clamp (4).

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a device for closing an end-side closing section of a packaging-forming flexible or pouch bag formed of a film material, with the closing device having a clamp surrounding a pigtail end for closing the end-side closing section and a cap surrounding a free end of the pigtail end. [0003] 2. Description of the Prior Art [0004] Chemical materials such as, e.g., sealing and adhesive materials are stored, nowadays, in flexible or pouch bags formed of a film material. For closing the end side closing section of a bag, the film material is gathered in a pigtail at the end of the closing section, and the pigtail end of the closing section is closed with a clamp that surrounds the pigtail end. One-or-two-component masses such as polyurethane systems, silicone masses, injectionable connecting mortar, can be examples of such material. Dependent on the filler material and the physical behavior of...
