[0010] In the paper-plastic cup structure, the maximum outer diameter of the cup bottom section is smaller than the minimum outer diameter of the cup body section, and the cup body section and the cup bottom section are connected by a lower connecting section in the form of a ring, and the vertical cross section of the connecting section is in the form of an inwardly concave arc to increase the connection strength of the cup body section and the cup bottom section.

[0011] In the paper-plastic cup structure, the upper end of the protrusion extends to the outer wall of the lower connecting section to support the connecting section upward, making the paper-plastic cup stronger.

[0012] In the paper-plastic cup structure, the cup mouth section is connected to the cup body section by an upper connecting section in the form of a taper, and the diameter of the upper connecting section gradually decreases from top to bottom, and the upper end of the protrusion extends to the outer wall of the upper connecting section to better support the cup mouth section upward, making the paper-plastic cup have better compression resistance.

The above design can expand the size of the cup mouth of the paper-plastic cup and enhance the user experience.

[0014] Compared with the prior art, the paper-plastic cup structure has the following advantages:

[0015] 1. A ring of uniformly distributed long strip protrusions is formed on the outer wall of the cup body section, and the protrusions are formed by outwardly concave from the inner side wall of the cup body section. This not only forms a similar vertical reinforcing rib effect on the outer wall of the cup body section to effectively enhance the compression resistance of the paper-plastic cup, but also increases the upward and downward sliding resistance and reduces the contact area between the hand and the cup body section, making the paper-plastic cup more comfortable to hold.

[0016] 2. The protrusions can strengthen the strength of the cup bottom section to provide stronger upward support, thereby further enhancing the compression resistance of the paper-plastic cup. BRIEF DESCRIPTION OF DRAWINGS

[0022] The following is a specific embodiment of the present application and further describes the technical scheme of the present application in combination with the drawings, but the present application is not limited to these embodiments.

[0023] As shown in Figure 1 and Figure 3 , the paper plastic cup structure comprises a cup mouth section 1 in the form of a ring, a cup body section 2 in the form of a conical cylinder, and a cup bottom section 3 in the form of a barrel, the cup mouth section 1, the cup body section 2 and the cup bottom section 3 are continuously distributed from top to bottom, and the diameter of the cup body section 2 gradually decreases from top to bottom.

[0024] Among them,

[0025] The cup mouth section 1 is composed of an upper conical section 1a and a lower straight cylinder section 1b, the diameter of the upper conical section 1a gradually decreases from top to bottom, the inner and outer diameters of the lower straight cylinder section 1b are the same as the minimum inner and outer diameters of the upper conical section 1a, and the upper conical section 1a and the lower straight cylinder section 1b are smoothly connected. With the above design, the size of the cup mouth of the paper plastic cup can be expanded, and the user experience can be enhanced. Preferably, the upper end of the upper conical section 1a is outwardly bent to form an annular flange 1c, so as to further enhance the user experience of the paper plastic cup.

[0026] As shown in Figures 1 to 4 , the lower straight cylinder section 1b is transitionally connected with the cup body section 2 through a conical upper connecting section 4, and the diameter of the upper connecting section 4 gradually decreases from top to bottom. The inner side wall of the cup body section 2 is outwardly recessed to form a circle of convex ribs 2a on the outer side wall of the cup body section 2, and the circle of convex ribs 2a is evenly distributed along the circumference of the cup body section 2. The convex rib 2a is in the form of a long strip, and the length of the convex rib 2a extends along the generatrix direction of the cup body section 2. The cross section of the convex rib 2a is in the form of a V, and the width of the convex rib 2a gradually decreases from top to bottom. In the actual product, the convex ribs 2a are arranged more densely to further enhance the overall strength of the paper plastic cup.

[0027] In use, the cup body section 2 is used for holding by hand.

[0028] A circle of evenly distributed long strip-shaped convex ribs 2a is formed on the outer wall of the cup body section 2, and the convex ribs 2a are outwardly recessed from the inner side wall of the cup body section 2, which not only forms a similar vertical reinforcing rib effect on the outer wall of the cup body section 2 to effectively enhance the compression resistance of the paper plastic cup, but also increases the sliding resistance and reduces the contact area between the hand and the cup body section 2, making the holding of the paper plastic cup more comfortable.

[0029] Preferably, the upper end of the protruding rib 2a extends to the outer wall of the upper connecting section 4 to better support the cup mouth section 1, thus improving the pressure resistance of the paper-plastic cup. The lower end of the protruding rib 2a extends to the section near the bottom of the cup 3.

[0030] The sidewall of the cup bottom section 3 is also conical, and the outer diameter of the cup bottom section 3 gradually decreases from top to bottom. The maximum inner and outer diameters of the cup bottom section 3 are smaller than the minimum inner and outer diameters of the cup body section 2, respectively. The cup body section 2 and the cup bottom section 3 are connected by a ring-shaped lower connecting section 5, and the vertical cross-section of the connecting section is concave arc-shaped to increase the connection strength between the cup body section 2 and the cup bottom section 3.

[0031] like Figure 1 and Figure 3 As shown, the inner wall of the cup bottom section 3 is recessed outward to form a ring of protrusions 3a on the outer wall of the cup bottom section 3, and the ring of protrusions 3a is evenly distributed circumferentially along the cup bottom section 3. The protrusions 3a enhance the strength of the cup bottom section 3, providing stronger upward support and further improving the pressure resistance of the paper-plastic cup. Preferably, the upper end of the protrusions 3a extends to the outer wall of the lower connecting section 5 to support the connecting section upward, resulting in better strength of the paper-plastic cup.
