As shown in fig. 1 to 11, the present invention provides a toothpaste housing for sharing toothpaste to avoid cross infection, comprising a housing 1, a toothpaste nozzle 2, an end cap (not shown in the figure), wherein the toothpaste nozzle 2 is disposed on the housing 1, and the toothpaste nozzle 2 is connected to the end cap, further comprising:

the first elastic sheet 3 comprises a first contact surface 301, a first non-contact surface 302, a first upper surface 303 and a first lower surface 304, wherein the first non-contact surface 302 is an arc-shaped surface, the left end and the right end of the first non-contact surface 302 are connected with the left end and the right end of the first contact surface 301, the first upper surface 303 is arranged at the tops of the first contact surface 301 and the first non-contact surface 302, and the first lower surface 304 is arranged at the bottoms of the first contact surface 301 and the first non-contact surface 302;

the second elastic sheet 4 is composed of a second contact surface 401, a second non-contact surface 402, a second upper surface 403 and a second lower surface 404, the second non-contact surface 402 is an arc-shaped surface, the left end and the right end of the second non-contact surface 402 are connected with the left end and the right end of the second contact surface 401, the second upper surface 403 is arranged at the tops of the second contact surface 401 and the second non-contact surface 402, and the second lower surface 404 is arranged at the bottoms of the second contact surface 401 and the second non-contact surface 402;

the first contact surface 30 and the second contact surface 401 are same in height and are adjacently arranged, the outer edge of the first lower surface 304 and the outer edge of the second lower surface 404 are both arranged on the upper surface of the toothpaste mouth 2, the first non-contact surface 302 and the second non-contact surface 402 are same in height and form a circle coaxial with the toothpaste mouth 2 therebetween, and the diameter of the circle is larger than the inner diameter of the toothpaste mouth 2 and smaller than or equal to the outer diameter of the toothpaste mouth 2.

In a specific embodiment, the end cap is screwed to the toothpaste nozzle 2, and the whole end cap is screwed off when using toothpaste, and in this toothpaste tube, the first elastic sheet 3 and the second elastic sheet 4 are disposed on the toothpaste nozzle 2. In another specific embodiment, the end cap is screwed with the toothpaste nozzle 2, but the end cap is also provided with a toothpaste nozzle and a cover body, the toothpaste nozzle is hinged with the cover body, and in this case, the first elastic sheet 3 and the second elastic sheet 4 are arranged on the toothpaste nozzle on the end cap.

In a specific embodiment, the adjacent gap between the first contact surface 301 and the second contact surface 401 is any one of a straight line shape, an S-shape and a zigzag shape. When the adjacent slits are S-shaped or zigzag-shaped, the ability to cut toothpaste when the adjacent slits are closed can be improved.

In a particular embodiment, the first elastic sheet 3 and the second elastic sheet 4 are symmetrically arranged. Therefore, on one hand, the appearance is more attractive; on the other hand, when the housing 1 is pressed or released, the first elastic sheet 3 and the second elastic sheet 4 are more uniformly stressed.

elastic sheets

3 and 4, and reduce the force required for opening and closing the first and second

elastic sheets

3 and 4, making it easier for the toothpaste to be squeezed out and broken.

In a specific embodiment, the first elastic sheet 3 and the second elastic sheet 4 are made of rubber or silicone.

When the toothpaste dispenser is used, the shell 1 is squeezed, toothpaste in the shell 1 moves towards the toothpaste mouth 2 under the action of pressure and transmits thrust to the first elastic sheet 3 and the second elastic sheet 4, the two elastic sheets are opened to form a toothpaste outlet under the action of the thrust, and the toothpaste is squeezed out. When the shell 1 is loosened, the pressure on the toothpaste inside disappears, and meanwhile, reverse suction force is generated according to the pressure difference between the inside and the outside of the shell 1, the two elastic pieces are automatically closed, and the toothpaste is automatically cut off under the shearing action of the two elastic pieces, so that cross infection is avoided.

In another specific embodiment, in order to solve the technical problem that the existing toothpaste shell is difficult to extrude when the toothpaste has little allowance, the toothpaste shell further comprises a toothpaste extruding ring 5, the inner diameter of the toothpaste extruding ring 5 is matched with the outer diameter of the shell 1, the toothpaste extruding ring 5 is sleeved on the lower part of the shell 1, and two pull rings 6 are symmetrically arranged on the toothpaste extruding ring 5.
