Definitions

  • the present invention relates to a reusable coffee capsule casing, and also to a coffee capsule using the casing and a corresponding coffee capsule brewing device (i.e., a capsule coffee machine), which belongs to the technical field of beverage preparation.
  • a coffee capsule is a beverage product that is specially treated to form a coffee powder and sealed in an aluminum foil capsule space while filling the capsule space with a non-toxic inert gas such as nitrogen to extend the shelf life.
  • the coffee capsule has many advantages such as stable quality, convenient drinking, convenient storage, energy saving and environmental protection, and is well received by coffee lovers.
  • the existing coffee capsule shells are generally made of aluminum foil material and can only be used once.
  • the main drawbacks are as follows: 1.
  • the base of the coffee capsule is designed with a protruding structure. When the coffee capsule brewing device is in operation, the base made of aluminum foil is pierced by the capsule needle, and then water is poured into the coffee powder of the coffee capsule. This will destroy the integrity of the coffee capsule, so the coffee capsule can only be used once; 2.
  • Higher cost The coffee powder contained in each coffee capsule is about 7 grams, which will cause the cost of using the coffee capsule once it is used. High in life; III.
  • the existing coffee capsule contains coffee powder, and the shelf life is generally only 11 months. If it is not used for more than 11 months, the whole coffee capsule must be discarded. 4.

Abstract

L'invention concerne un boîtier pour capsule de café réutilisable, une capsule de café utilisant le boîtier, et un dispositif d'infusion correspondant pour la capsule de café. Le boîtier pour capsule de café comporte un corps de contenant (a), un couvercle (b), et un pont de raccordement (c). Le pont de raccordement (c) est raccordé entre le corps de contenant (a) et le couvercle (b). Une base de positionnement (a2) est disposée sur un fond supérieur du corps de contenant (a). Une rainure annulaire anti-perçage (a1) est prévue autour de la base de positionnement (a2). Une admission d'eau (a4) est prévue sur le fond de la rainure anti-perçage (a1). Le couvercle (b) recouvre l'orifice d'extrémité inférieure du corps de contenant (a) par une bordure cylindrique (b5) ayant un rebord vertical. Des nervures de renfort (b1) distribuées dans le sens radial sont disposées sur une surface inférieure du couvercle (b) depuis une périphérie jusqu'à une partie centrale. Des sorties d'eau (b2) sont prévues entre les nervures de renfort (b1). Le boîtier pour capsule de café est conçu avec une structure unique concave et convexe. Lors de l'utilisation, l'intégrité de la capsule de café n'est pas affectée, de sorte que le boîtier pour capsule de café peut être utilisé de manière répétée, pour ainsi réduire considérablement le coût d'utilisation. Le café en poudre est acheté lorsque cela est nécessaire, pour ainsi éviter tout gaspillage dû à l'expiration de la capsule de café, ceci étant bénéfique pour la protection de l'environnement et l'économie des ressources.
