Title: DUAL-TUBE MIXING AND DISPENSING PEN
Abstract:
A dual-tube mixing and dispensing pen, comprising: a pen body (1), a dispensing tube (2), and an end cap (3). The dispensing tube (2) and the end cap (3) are respectively installed on two ends of the pen body (1). The pen body (1) is internally provided with at least two cavities (10) independent from each other. A dispensing opening (11) is provided at an end, proximal to the dispensing tube (2), of each of the cavities (10). An actuator (4) is provided at an end, proximal to the end cap (3), of each of the cavities (10). The actuator (4) comprises a plunger (41), a screw shaft, and a nut (44). The plunger (41) forms a radial snap fit connection with the screw shaft and is fixed along an axial direction. The screw shaft and the matching nut (44) are engaged by means of a screw thread (5). The end cap (3) meshes with each of the nuts (44) by means of a gear (6). A mixing core (7) is provided within the dispensing tube (2) at location outside the dispensing opening (11) of the pen body (1). Two different types of internal materials are not mixed during filling, but are only mixed during use. The invention can effectively ensure that a characteristic of the internal material remains largely unchanged and can satisfy a consumer requirement.
