Device and method for reinforcing a blister

Abstract

A device and method for reinforcing a blister, including a transport mechanism for transporting the blister, and a centering mechanism that bring the blister into a particular position in the direction transverse to the travel direction of the transport mechanism. A gluing station applies an adhesive to the blister and / or to a card, with the card having at least one opening that is matched to the geometry of a pocket of the blister. An insertion device is provided that sets the card into place on the blister.

Description

BACKGROUND OF THE INVENTION[0001]The invention is based on a device and method for reinforcing a blister, as generically defined by the preambles to the independent claims. A device for inserting a packaged good into packaging, in particular for inserting blister strips into folding cardboard boxes, is already known from EP 1 389 166 B1. After the blister has been inserted into the folding cardboard box, the latter is closed in a conventional way. It is necessary, however, to modify this device if in lieu of a conventional folding cardboard box, a blister strip is to be stored in a so-called wallet pack—a folding cardboard box in the form of a billfold that can be folded open and then closed again. The blister to be stored must be attached to this packaging and is therefore subjected to greater mechanical stresses.OBJECT AND SUMMARY OF THE INVENTION[0002]The object of the present invention is to modify the species-defining device so that it permits the manufacture of a stable wallet...

AI Technical Summary

Benefits of technology

[0003]The device and method according to the invention for reinforcing a blister have the advantage over the prior art that the blister is stabilized by placing a card onto it. This type of stabilization is also suitable for a better attachment of the packaged good to the wallet pack because the gluing of the card that covers the blister stabilizes the blister and holds it in position in the wallet. The centering means contribute to a very precise positioning of the blister. The card can be placed onto the blister so that the openings enclose the pockets in a uniform way. This also improves the visual appearance of the blister in the wallet pack.

[0005]In a suitable modification, at least one guide rail is used as a centering means and at least one lateral edge of the blister or pocket that is parallel to the direction of travel is guided against this rail. This type of centering brings the blisters into an approximate position in a simple way. Another guide rail can be provided, which is oriented in the travel direction and cooperates with at least one pocket of the blister in order to center the blister. This guide rail, which preferably influences the central region of the blister, aligns the blister even more precisely since the card's position must match exactly, in particular because the card is to cover over the pockets. This type of centering makes a further contribution to positioning precision.

[0006]In a suitable modification, a die is used as part of the insertion device and, with the aid of vacuum, places the card onto the blister. Thanks to the use of vacuum, it is also possible for different card sizes to be reliably picked up and inserted, without having to change the die.

[0007]In a suitable modification, the die presses the card against the blister. This makes it possible to more quickly produce a glued connection between the card and blister without having to provide an additional device for this.

Problems solved by technology

The blister to be stored must be attached to this packaging and is therefore subjected to greater mechanical stresses.
