Preferably, the extrusion section, the circular table section and the cylindrical section of the extrusion structure are connected in sequence.
Preferably, the circular truncated cone section is an elliptical truncated cone section; the elliptical circular table section is made of an elastic material, and the cross sectional area of the elliptical circular table section is larger than that of the storage section of the cylinder when the elliptical circular table section is not extruded; after the elliptical truncated cone section enters the storage section of the cylinder, the elliptical truncated cone section is tightly attached to the inner wall of the storage section due to the extrusion of the elliptical truncated cone section; the paste can only move from the tail part of the barrel to the outlet section, and the paste in the storage section after the extrusion structure moves can be completely extruded.
Preferably, the cylindrical section of the extruding structure is in clearance fit with the outlet section of the barrel, and the cylindrical section can further extrude the paste at the outlet section, so that the paste is completely extruded out of the barrel.
Preferably, the cream in the barrel is ointment, toothpaste or facial cleanser.
Preferably, the material of the barrel is aluminium or plastic; squeezing from the tail of the barrel, wherein the squeezing structure moves from the tail of the barrel to the outlet section and pushes the paste.
Preferably, in the initial position, the elongate pressing section of the pressing structure is in contact with the tail of the barrel. The utility model adopts the technical scheme of the utility model, which has the following beneficial effects:
compared with the structure of the traditional barrel, the extruding device for the paste is characterized in that the extruding structure is designed in the barrel, so that the paste is pushed out by pushing the extruding structure, and the extruding structure is in interference fit with the inner wall of the barrel, so that the paste remained on the inner wall of the barrel can be extruded out when the paste is pushed, and waste is avoided.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, the present embodiment provides a paste extruding apparatus, which includes an extruding structure 1 and a toothpaste tube 2. The toothpaste tube 2 comprises a flat tail portion 201, a hollow storage section 202 and an outlet section 203, the extrusion structure 1 comprises an extrusion section 101, an elliptical circular truncated cone section 102 and a cylindrical section 103, and the elliptical circular truncated cone section 102 is in contact with the storage section 202 of the toothpaste tube or the ointment tube 2.
Figure 1 shows the initial stage when toothpaste is not in use, with the squeezing section 101 extending into the rear portion 201 of the cartridge 2. As shown in fig. 1 and 2, when the toothpaste tube 2 is pressed at the tail part 201 of the toothpaste tube 2, the elliptical truncated cone section 102 is pressed to fit the tail part 201.
The material of the elliptical truncated cone segment 102 is an elastic material and has an initial (when not compressed by the tail or the interior of the storage segment) cross-sectional area that is greater than the cross-sectional area of the interior wall of the storage segment 202.
As shown in fig. 3, during use of the toothpaste, the extrusion structure 1 is pushed to move from the tail portion 201 to the outlet section 203.
As shown in fig. 4, when the compression structure 1 is fully in the storage section 202 of the toothpaste tube 2, the elliptical truncated cone section 102 of the compression structure 1 is released.
As shown in FIG. 5, when the squeezing structure 1 is moved to the outlet section 203 of the toothpaste tube 2, the cylindrical section 103 is in clearance fit with the outlet section 203, which helps to further push the toothpaste.
The working principle is as follows: when toothpaste is needed, the extrusion section 101 of the extrusion structure 1 is pushed by a hand, and then the toothpaste is pushed to flow out from the outlet section 203, and because the elliptical truncated cone section 102 of the extrusion structure 1 is of an elastic structure and the initial cross-sectional area of the elliptical truncated cone section is larger than the maximum cross-sectional area of the inner wall of the storage section 202, when the extrusion structure 1 moves forward, the elliptical truncated cone section 102 and the storage section 202 of the toothpaste tube 2 are in interference fit, so that the toothpaste or the ointment is prevented from reversely flowing out, and meanwhile, the residual toothpaste or the ointment attached to the inner wall of the storage section 202 is extruded to the outlet section 203, and the waste is reduced.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the utility model.
