(54) REFILL DEVICE


(57) The present invention discloses a refill device, comprising a case body (31), wherein the case body (31) has an opening end (311), a first case body (312) and a case bottom (32); the case bottom (32) is integrally formed with the first case body (312); the case bottom (32) of the case body (31) is provided with a first cutting line (34) for enclosing a portion to form a bottom bracket (35); and the bottom bracket (35) is separable from the case bottom (32) along the first cutting line (34) under the action of an external force. The case bottom (32) of the present invention is integrally formed with the first case body (312), and the first cutting line (34) is provided on the case bottom (32) to form a separable bottom bracket (35), which is used in cooperation with the packaging device in the embodiment of the present invention, so that the packaging device can be reused. Integrally forming the case bottom (32) and the first case body (312) reduces the number of accessories, reduces the production cost of the product and improves the production efficiency, while reducing the logistics cost and the production cost of the filling line.
