DETAILED DESCRIPTION
[0018] The technical solutions in the embodiments of the present utility model will be described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0019] A rotating liner type hard tube toothpaste comprises an outer shell and a rotating liner, wherein a first extrusion port is provided at one end of the rotating liner, a second extrusion port is provided at one end of the outer shell, and the other end is open, the outer shell is sleeved on the outside of the rotating liner, the first extrusion port of the rotating liner is fixedly buckled with the second extrusion port of the outer shell, and the other end of the rotating liner is rotatably buckled with the open end of the outer shell. The rotating liner comprises an upper cover, a lower cover and an inner bag, the upper edge of the inner bag is pasted together with the edge of the upper cover, the lower end of the inner bag is pasted together with the lower cover, the inner bag is a cavity for filling a medium, and the first extrusion port is arranged in the middle of the upper cover. A notch structure is provided on the surface of the second extrusion port, a hollow convex column is provided in the middle of the upper cover, and a convex clamping point corresponding to the notch structure is provided on the surface of the hollow convex column. A plurality of tooth-shaped grooves arranged equidistantly are provided on the edge of one end of the outer shell opening, and a plurality of tooth-shaped protrusions corresponding to the tooth-shaped grooves are provided on the inner wall surface of the lower cover, and the two are tightly matched and can rotate relative to each other. The upper end of the shell is also provided with a cover body, and a third extrusion port is provided in the middle of the cover body. The third extrusion port is sleeved outside the second extrusion port, and the cover body is fixedly arranged on one side of the second extrusion port of the shell. The cover body includes a base and a flip cover, the base is fixed on one side of the second extrusion port of the shell, and the flip cover is connected to the edge of the base. When the flip cover cooperates with the base, the third extrusion port can be closed. A positioning groove is also provided on one side of the opening of the shell, and a positioning strip is provided on the inner wall of the lower cover of the rotating inner liner. The positioning groove and the positioning strip are engaged, which can prevent the rotating inner liner and the shell from relative axial movement.
[0020] The production and assembly process is as follows:
[0021] The rotating liner and the outer shell are axially positioned at the first point through the raised card point on the surface of the first extrusion port and the notch structure on the surface of the second extrusion port, and then the lower cover at the bottom of the rotating liner is tightly fitted at the opening of the outer shell. A positioning groove can be set on the surface of the opening to cooperate with the positioning strip on the inner wall of the lower cover to achieve the second point axial positioning. Finally, the cover body is fixedly installed on the side of the second extrusion port of the outer shell to complete the overall assembly of the toothpaste. The tooth-shaped protrusion of the lower cover and the tooth-shaped groove at the opening of the outer shell are tightly matched with each other and can rotate when a certain torque is applied.
[0022] When using:
[0023] The lower cover of the rotating inner liner is rotated, and the lower cover drives the inner bag of the rotating inner liner to be tightened. During the tightening process, the toothpaste storage space in the inner bag is compressed, and the compressed part of the toothpaste is discharged through the first extrusion port, thereby achieving quantitative extrusion of the toothpaste. When not in use, the flip cover is closed to block the third extrusion port to prevent the toothpaste from being accidentally squeezed out.
[0024] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is limited by the appended claims rather than the above description, and it is intended that all changes within the meaning and scope of the equivalent elements of the claims are included in the present invention.
