DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1-Figure 4The shoulder cover shown includes a skirt shoulder 1, an outer cover 2 and an inner cover 3. The skirt shoulder 1 is provided with a connecting hole 11. The bottom of the outer cover 2 is inserted through the connecting hole 11. The bottom of the outer cover 2 is riveted to the skirt shoulder 1 at the position of the connecting hole 11. The inner cover 3 is installed on the inner side of the outer cover 2. The inner cover 3 is fixedly connected to the outer cover 2. The utility model decomposes the shoulder cover into three parts: the skirt shoulder 1, the outer cover 2 and the inner cover 3. After decomposition, the external structure of each component becomes very simple, which is conducive to low-cost mold production. After the three parts are completed, they are assembled together into a shoulder cover product. The shoulder cover product has the advantage of low production cost, which is conducive to increasing product profits and enhancing the market competitiveness of the product. The utility model makes the skirt shoulder 1 and the outer cover 2 of aluminum material, so that the shoulder cover product still has the advantage of being light and thin. The inner cover 3 needs to be connected to the bottle head, so it is made of low-cost and light-weight plastic. The shoulder cover product of the utility model still has the advantages of beautiful appearance and overall lightness and thinness, which can meet the customer's usage needs.

[0028] like Figure 3 As shown, the outer wall diameter of the jacket 2 matches the diameter of the connecting hole 11. During assembly, the jacket 2 can be fitted into the connecting hole 11. A first convex ring 21 is provided on the outer wall of the jacket 2. The diameter of the first convex ring 21 is larger than the outer wall diameter of the jacket 2. That is to say, the diameter of the first convex ring 21 is also larger than the diameter of the connecting hole 11. The insertion limit function of the jacket 2 can be formed under the obstruction of the first convex ring 21, and the part below the first convex ring 21 can be inserted into the connecting hole 11. Since the position of the first convex ring 21 is fixed, the insertion length of the bottom of the jacket 2 is also fixed, which can ensure that the shoulder sleeve products produced are highly consistent.

[0029] like Figure 1 As shown, the connecting hole 11 is opened in the central position of the skirt shoulder 1, so that the jacket 2 is installed in the center, and the product appearance is more beautiful. The outer wall of the jacket 2 is connected with a positioning ridge 23, and a positioning notch 12 is opened at the edge of the connecting hole 11. The size of the positioning ridge 23 matches the positioning notch 12, and the positioning ridge 23 is arranged below the first ridge 21. In this way, the first ridge 21 does not affect the docking installation of the positioning ridge 23 and the positioning notch 12. When the jacket 2 is installed, the positioning ridge 23 is aligned with the positioning notch 12 to be inserted. This design can realize the positioning connection between the jacket 2 and the skirt shoulder 1, while ensuring that the jacket 2 cannot rotate relative to the skirt shoulder 1. This design can enhance the connection reliability between the jacket 2 and the skirt shoulder 1.

[0030] In the present invention, there is also a need to fix the inner sleeve 3 to the outer sleeve 2. The first convex ring 21 of the outer sleeve 2 is processed by the rolling process. The characteristics of the rolling process are as follows: Figure 3 and Figure 4As shown, a groove 22 is formed on the inner wall of the outer sleeve 2 corresponding to the first convex ring 21, and a second convex ring 31 is provided on the outer wall of the inner sleeve 3. The groove 22 formed on the inner wall of the outer sleeve 2 can be used to connect the inner sleeve 3. The size of the second convex ring 31 of the inner sleeve 3 is set to match the groove 22. When the inner sleeve 3 is installed from bottom to top, the inner sleeve 3 is snap-connected to the inner side of the outer sleeve 2 through the cooperation of the second convex ring 31 and the groove 22. In order to further improve the connection reliability between the inner sleeve 3 and the outer sleeve 2, glue is coated on the surface of the second convex ring 31. In this way, there is both a snap connection and auxiliary glue bonding. The inner sleeve 3 and the outer sleeve 2 are reliably connected after installation.

[0031] like Figure 1 As shown, a through hole 24 of the same size is opened on the top of the outer sleeve 2 and the inner sleeve 3, and the through hole 24 is reserved for the pump head component of the cosmetic bottle container.

[0032] like Figure 1 As shown, the skirt shoulder 1 and the jacket 2 of the present invention are connected by riveting. The advantage of riveting is that the connection position is in a dark place, which not only realizes the connection function but also ensures the beauty of the shoulder cover product. In order to cooperate with the production and processing of the shoulder cover product, Figure 5 and Figure 6 As shown, the utility model designs a riveting processing device, which is used for the riveting processing operation of the two components of the skirt shoulder 1 and the jacket 2. A riveting processing device includes a mold base 4, a lower mold base 5 and a punching machine 7. The lower mold base 5 is installed on the mold base 4, and the lower mold base 5 can move vertically up and down. A riveting column 6 is installed at the center of the lower mold base 5. The bottom of the riveting column 6 is fixedly connected to the mold base 4. During the lifting and lowering movement of the lower mold base 5, the top of the riveting column 6 and the lower mold base 5 have the effect of changing relative positions. The punching machine 7 is installed on the side of the mold base 4. The punching machine 7 includes a machine head 71. The machine head 71 is movably equipped with a lifting column 72. The bottom of the lifting column 72 is fixedly connected to the upper mold base 8. The punching machine 7 provides power for the upper mold base 8 to move up and down. The upper mold base 8 and the lower mold base 5 take an up and down vertical motion. The corresponding setting is that the upper die base 8 can be separated from the lower die base 5 when it rises, and can be assembled with the lower die base 5 when it descends, and can form the effect of pushing the lower die base 5 to descend together. After the upper die base 8 and the lower die base 5 are assembled, a workpiece cavity 9 is formed between the two. The workpiece cavity 9 can match and accommodate the assembly of the skirt shoulder 1 and the outer jacket 2. Before placing them into the workpiece cavity 9, the skirt shoulder 1 and the outer jacket 2 are first positioned and assembled. When the upper die base 8 is separated from the lower die base 5, the workpiece cavity 9 is open, which is just used to place the assembly of the skirt shoulder 1 and the outer jacket 2. When the lower die base 5 is in the rising state, the top of the rivet column 6 does not enter the workpiece cavity 9, which does not affect the placement operation of the skirt shoulder 1 and the outer jacket 2 assembly. The lower die base 5 can be pushed down by the upper die base 8, and the top of the rivet column 6 can enter the workpiece cavity 9 and press on the bottom of the outer jacket 2. Figure 3 As shown, the bottom of the jacket 2 is pressed outward by the top of the riveting column 6, and then a riveted connection effect can be formed with the skirt shoulder 1.

[0033] like Figure 6 As shown, the workpiece cavity 9 includes a first half cavity 91 and a second half cavity 92. The first half cavity 91 is provided on the upper die base 8, and the second half cavity 92 is provided on the lower die base 5. The second half cavity 92 is connected to the top of the riveting column 6, so that the top of the riveting column 6 can enter the workpiece cavity 9 to complete the riveting connection of the workpiece. After the upper die base 8 and the lower die base 5 are assembled, the first half cavity 91 and the second half cavity 92 can form a complete workpiece cavity 9. The outer dimensions of the workpiece cavity 9 match the outer dimensions of the assembly of the skirt shoulder 1 and the jacket 2. The riveting operation needs to be completed during the assembly process of the upper die base 8 and the lower die base 5. At this time, the skirt shoulder 1 and the jacket 2 assembly in the workpiece cavity 9 can be firmly positioned and fixed to successfully complete the riveting operation.

[0034] like Figure 6 As shown, a plurality of spring holes 51 are provided at the bottom of the lower die base 5, and springs 52 are installed in the spring holes 51. A plurality of mold guide assemblies 41 are installed on the die base 4. The mold guide assemblies 41 and the spring holes 51 are arranged in a one-to-one correspondence. The mold guide assembly 41 includes a vertical rod 411 and a guide pressure plate 412. The vertical rod 411 is upright and fixed to the die base 4, and the guide pressure plate 412 is connected to the top of the vertical rod 411. The guide pressure plate 412 is matched and installed in the spring hole 51. The guide pressure plate 412 is fixedly connected to the bottom end of the spring 52. The guide pressure plate 412 plays a guiding role in the movement of the lower die base 5, so that the lower die base 5 can only move vertically up and down. The lower die base 5 is supported by the spring 52. The spring 52 has an elastic support effect, so the lower die base 5 can be pushed downward by the upper die base 8. At this time, the spring 52 is compressed. After the lower die base 5 loses the downward force, it is affected by the restoring force of the spring 52 and the lower die base 5 can return to the upward state.
