Abstract

Sont divulgués dans la présente demande une boîte d'emballage et une structure en carton. La boîte d'emballage comprend : une boîte externe, qui s'étend dans une première direction et comprend une première partie de paroi, au moins une extrémité de la première partie de paroi dans la première direction étant dotée d'une première ouverture, et la première partie de paroi comprenant une première ouverture de verrouillage pénétrant à travers celle-ci ; et une boîte interne, qui est configurée pour se raccorder de manière coulissante à la boîte externe dans la première direction à travers la première ouverture et comprend une seconde partie de paroi et une structure de languette de verrouillage. La seconde partie de paroi comprend une seconde ouverture de verrouillage, qui pénètre à travers celle-ci, et une structure de support d'article ; et la structure de languette de verrouillage est située au niveau de la seconde ouverture de verrouillage, et au moins une partie de la structure de languette de verrouillage est située sur un côté interne de la seconde partie de paroi et est reliée à la seconde partie de paroi dans un mode plié. Après que la boîte interne coulisse dans la boîte externe, la structure de languette de verrouillage passe à travers la seconde ouverture de verrouillage et la première ouverture de verrouillage. Dans la présente invention, tout en facilitant le recyclage, la structure de la boîte d'emballage est simplifiée, et la boîte d'emballage peut être verrouillée et déverrouillée, ce qui permet de réduire le risque d'ouverture accidentelle de la boîte d'emballage.
