[0023] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.
[0024] Please refer to Figure 1-5The pulp molding container cover 100 of the present invention includes a cover body 10, which includes an end wall 1 and an annular circumferential wall 2. The end wall 1 is arranged at one axial end of the annular circumferential wall 2, and at least one groove 21 is provided at the other end opening of the annular circumferential wall 2 away from the end wall 1. A side plate 3 is bonded and fixed in the groove 21, and a threaded structure is provided on the side plate 3. The threaded structure is used to connect the pulp molding container cover 100 to the container.
[0025] The thread structure comprises multiple strip-shaped protrusions 31 extending along the same helical line to meet the requirements of the thread structure. These strip-shaped protrusions 31 can increase the mating area with the thread structure on the container, thereby improving the connection reliability between the pulp molded container cap 100 and the container. The thread structure can also be a plurality of hemispherical protrusions spaced apart along the same helical line. Hemispherical protrusions save material and reduce the friction area with the thread structure on the container, making the pulp molded container cap 100 fit more smoothly with the container.
[0026] There are multiple grooves 21 and they are spaced apart along the circumference of the annular circumferential wall 2, and there are multiple side plates 3 and they fit into the grooves 21 one by one. The side plates 3 are directly formed into an arc-shaped plate, or are bent from a formed flat plate into an arc-shaped plate.
[0027] The side panels 3 are adhesively fixed to the grooves 21 provided on the annular peripheral wall 2 of the lid body 10, and the adhesive contact area is larger, making the adhesive bond more secure. The grooves 21 provided on the annular peripheral wall 2 of the lid body 10 limit the position of the side panels 3, so that when the lid is screwed on, the side panels 3 will not rotate relative to the lid body 10, thereby improving the reliability of the connection between the side panels 3 and the lid body 10. Moreover, when assembling the side panels 3 and the lid body 10, the grooves 21 can be used for pre-positioning, ensuring that the side panels 3 are adhesively fixed in the correct position. The side panels 3 are slid into the grooves 21 of the annular peripheral wall 2 from the side away from the end wall 1, making the assembly of the pulp molded container lid 100 simpler and more efficient, and facilitating automated assembly. The pulp molded container lid 100 of this embodiment has the advantage of being structurally stable and can be smoothly screwed to or separated from the container.
[0028] The circumferential length L of the groove 21 gradually decreases in the direction toward the center axis V of the annular peripheral wall 2 (for example Figure 3 In the direction X shown in the figure, the cross section of the groove 21 is generally fan-shaped, or the groove 21 is a dovetail groove, so as to limit the side plate 3 from escaping from the groove 21 in the direction of the central axis V of the annular peripheral wall 2.
[0029] In summary, the present invention provides a pulp molded container cover 100, the cover body 10 of the pulp molded container cover 100 includes an end wall 1 and an annular circumferential wall 2, the end wall 1 is arranged at one axial end of the annular circumferential wall 2, and a groove 21 is provided at the opening of the other end of the annular circumferential wall 2 away from the end wall 1, and a side plate 3 is fitted in the groove 21, and a threaded structure is provided on the side plate 3, which is used to connect the pulp molded container cover 100 with the container. The pulp molded container cover 100 of the present invention has the characteristics of good structural stability and can be smoothly screwed together or separated from the container.
