An envelope (11) consisting of a front side (12) and a rear side (16) which are interconnected by side flaps (19), has a fold-back flap (18) to which a layer of contact adhesive (23) is applied. The adhesive used is a strong contact adhesive which is effective without moistening or activation by any other means. The fold-back flap is laid against the rear side (16) of the envelope for the purposes of transport and storage, an area (22) coated with a parting agent being provided so that the adhesive can be detached before use. The envelope is closed by pressing the otherwise uncoated closing flap (14) onto the adhesive-coated fold-back flap. The adhesive is applied to the fold-back flap (18) by transfer, i.e. the adhesive is applied to the parting agent layer (22) during production and then transferred to the fold-back flap when the latter is redressed.
L'invention concerne une enveloppe (11), constituée d'un recto (12) et d'un verso (16) assemblés par l'intermédiaire de rabats latéraux (19) et comportant un rabat repliable (18) sur lequel est appliquée une couche adhésive (23) consistant en une colle adhésive forte agissant sans humidification ni autre activation. Pour le transport et le stockage, le rabat repliable est appliqué contre le verso (16) de l'enveloppe, une bande (22) enduite d'agent de séparation permettant de séparer à nouveau l'adhésif avant utilisation. Pour fermer l'enveloppe, on appuie le rabat de fermeture (14) non enduit sur le rabat repliable adhésif. L'application de l'adhésif sur le rabat repliable (18) se fait par transfert, l'adhésif appliqué sur la couche d'agent de séparation (22) lors de la fabrication étant transféré sur le rabat repliable lorsqu'on redresse ce dernier.
