Document Type and Number:
WIPO Patent Application WO/2024/011787
Kind Code:
A1
Abstract:
A toothpaste dispenser, comprising a toothpaste tube body (1). An internal check valve (7) is sleeved at the top of the toothpaste tube body (1), and an external thread (14) is provided at the periphery of the top of the internal check valve (7); a fixing sleeve (10) is fixedly connected to the top of the internal check valve (7), and an internal thread (15) is provided at the inner circumference of the fixing sleeve (10); the internal thread (15) and the external thread (14) are screwed together; and an inner cavity body (5) is mounted on the top of the fixing sleeve (10). The toothpaste dispenser is directly mounted at the top of a toothpaste tube, and does not need to be fixed to a wall surface for use, so that the portability of the device is improved; moreover, the inner cavity body (5) is pressed, the gas in the inner cavity body (5) is discharged by means of an external check valve (11), and a negative pressure is formed inside the inner cavity body (5), so that toothpaste is suctioned into the inner cavity body (5) by means of the internal check valve (7), and is then squeezed out by means of the external check valve (11) and a dispensing nozzle (3), so that vacuum negative-pressure toothpaste dispensing is achieved, and mechanical toothpaste dispensing is replaced. The toothpaste dispenser is beneficial to ensuring that the toothpaste is squeezed out more completely, thereby reducing residues in the toothpaste tube.
