Embodiment of the present application

[0049] In order to further explain the technical solutions of the present application, the present application is described in detail below through specific examples.

[0050] Below, referring to the drawings, the embodiment of the pulp molded connector 30 of the present application is described as follows.

[0051] As shown in Figs. 1 and 2, the pulp molded connector 30 is formed by jointing the pulp molded plates 11 to form an annular body 1, wherein “jointing” refers to both “enclosing jointing” and “connecting”, the pulp molded plates 11 are non-annular in structure, and the annular body 1 is formed by enclosing jointing and connecting the pulp molded plates 11, the annular body 1 is formed into a ring shape by the “enclosing jointing” of the pulp molded plates 11, and the ring shape is maintained by the “connecting” of the pulp molded plates 11, and cannot be automatically unfolded into a non-annular shape.

[0052] For example, the connecting in the jointing can be achieved by bonding between the end portions of different pulp molded plates 11, or can be achieved by bonding between the two end portions of the same pulp molded plate 11; for another example, the connecting in the jointing can be achieved by clamping jointing between the end portions of different pulp molded plates 11, or can be achieved by clamping between the two end portions of the same pulp molded plate 11.

[0053] The connecting structure 2 is formed on the peripheral wall surface of the annular body 1, that is, one of the inner peripheral surface and the outer peripheral surface of the annular body 1 is provided with the connecting structure 2, and the connecting structure 2 is used to connect the container cap 10 and the container 20, as shown in Figs. 3-6.

[0054] For example, in combination with FIGS. 1 and 2, when the pulp molded connecting piece 30 is formed into the ring body 1 by splicing the pulp molded plate 11, the connecting structure 2 can be integrally formed on the pulp molded plate 11 first, and then the pulp molded plate 11 with the connecting structure 2 is spliced into the ring body 1, so that the connecting structure 2 is formed on the peripheral wall surface of the spliced ring body 1.

[0055] For example, in combination with FIG. 7, when the pulp molded connecting piece 30 is formed into the ring body 1 by splicing the pulp molded plate 11, the connecting structure 2 can be integrally formed on at least one of the pulp molded plates 11 first, and then the pulp molded plates 11 are spliced into the ring body 1, so that the connecting structure 2 is formed on the peripheral wall surface of the spliced ring body 1.

[0056] In this way, the connecting structure 2 can be integrally formed on the non-ring-shaped pulp molded plate 11 through the pulp molding process, so that the manufacturing of the pulp molded connecting piece 30 is easy to achieve, and then the ring body 1 in a stable ring shape is obtained by splicing the pulp molded plates 11, thereby facilitating the installation of the ring body 1 on the container cover 10 or the container 20. Moreover, the pulp molded connecting piece 30 is made of pulp molding material, which is green and environmentally friendly.

[0057] In the case where the pulp molded connecting piece 30 is formed into the ring body 1 by splicing the pulp molded plates 11, the splicing manner of the pulp molded plates 11 is not limited, for example, at least two pulp molded plates 11 are spliced along the circumferential direction X of the ring body 1; for example, at least two pulp molded plates 11 are spliced along the circumferential direction X of the ring body 1, and at the same time, at least two pulp molded plates 11 are spliced along the axial direction Z of the ring body 1, and the like.

[0058] In the case where the pulp molded connecting piece 30 is formed into the ring body 1 by splicing the pulp molded plates 11, the splicing manner of the pulp molded plates 11 is not limited, for example, at least two pulp molded plates 11 are spliced along the circumferential direction X of the ring body 1; for example, at least two pulp molded plates 11 are spliced along the circumferential direction X of the ring body 1, and at the same time, at least two pulp molded plates 11 are spliced along the axial direction Z of the ring body 1, and the like.

[0059] In the case where the pulp molded connecting piece 30 is formed into the ring body 1 by splicing the pulp molded plates 11, the splicing manner of the pulp molded plates 11 is not limited, for example, at least two pulp molded plates 11 are spliced along the circumferential direction X of the ring body 1; for example, at least two pulp molded plates 11 are spliced along the circumferential direction X of the ring body 1, and at the same time, at least two pulp molded plates 11 are spliced along the axial direction Z of the ring body 1, and the like.

[0060] Exemplarily, the container 20 is a bottle, the container cover 10 is a bottle cap, the bottle mouth of the bottle is a mouth ring 20a, the outer periphery of the mouth ring 20a has an outer thread as a matching structure, the pulp molded connecting piece 30 is arranged in the bottle cap and is arranged around the inner periphery of the bottle cap, and the connecting structure 2 is arranged as an inner thread suitable for matching with the outer thread.

[0061] Exemplarily, the container 20 is a bottle, the container cover 10 is a bottle cap, the bottle mouth of the bottle is a mouth ring 20a, the outer periphery of the mouth ring 20a has an outer thread as a matching structure, the pulp molded connecting piece 30 is arranged in the bottle cap and is arranged around the inner periphery of the bottle cap, and the connecting structure 2 is arranged as an inner thread suitable for matching with the outer thread.

[0062] Exemplarily, the container 20 is a bottle, the container cover 10 is a bottle cap, the bottle mouth of the bottle is a mouth ring 20a, the outer periphery of the mouth ring 20a has an outer thread as a matching structure, the pulp molded connecting piece 30 is arranged in the bottle cap and is arranged around the inner periphery of the bottle cap, and the connecting structure 2 is arranged as an inner thread suitable for matching with the outer thread.

[0063] Exemplarily, the container 20 is a bottle, the container cover 10 is a bottle cap, the bottle mouth of the bottle is a mouth ring 20a, the outer periphery of the mouth ring 20a has an outer thread as a matching structure, the pulp molded connecting piece 30 is arranged in the bottle cap and is arranged around the inner periphery of the bottle cap, and the connecting structure 2 is arranged as an inner thread suitable for matching with the outer thread.

[0064] Therefore, according to the pulp molded connecting piece 30 of the embodiment of the present application, since the pulp molded connecting piece 30 is spliced by the pulp molded plate 11 to form the annular body 1, the connecting structure 2 is formed on the peripheral wall surface of the annular body 1, so that the connecting structure 2 can be integrally formed on the non-annular pulp molded plate 11 through the pulp molding process, the manufacturing of the pulp molded connecting piece 30 is easy to realize, and then the annular body 1 is obtained by splicing the pulp molded plate 11, so that the annular body 1 is convenient to install on the container cover 10 or the container 20. Moreover, the pulp molded connecting piece 30 is made of pulp molding material, which is green and environmentally friendly.

[0065] In some embodiments of the present application, as shown in FIGS. 1 and 2, the pulp molded plate 11 is formed into a strip-shaped pulp molded plate 111, that is, the strip-shaped pulp molded plate 111 is a long strip-shaped plate structure, the annular body 1 is surrounded by bending one strip-shaped pulp molded plate 111 into a ring shape, and the first end and the second end in the length direction of the strip-shaped pulp molded plate 111 are spliced. Among them, one end of the two ends in the length direction of the strip-shaped pulp molded plate 111 is the first end 111a, and the other end is the second end 111b. The splicing of the first end and the second end in the length direction of the strip-shaped pulp molded plate 111 can be understood as the splicing of the first end 111a and the second end 111b of the strip-shaped pulp molded plate 111.

[0066] Thus, the pulp molded plate 11 has a simple structure and is easy to manufacture. The pulp molded connecting piece 30 is formed by splicing a plurality of strip-shaped pulp molded plates 111, so that the splicing times are reduced, the splicing efficiency is improved, and the annular body 1 has only one splicing seam 12, so that the probability of the annular body 1 being cracked from the splicing seam 12 is reduced, and the structural stability of the annular body 1 is improved.

[0067] For example, in production, the connecting structure 2 can be integrally formed on one side surface of the strip-shaped pulp molded plate 111 in the thickness direction, the strip-shaped pulp molded plate 111 with the connecting structure 2 is bent to form a ring shape, and then the first end and the second end of the strip-shaped pulp molded plate 111 in the length direction are spliced to obtain the annular body 1.

[0068] In some embodiments of the present application, as shown in FIGS. 7 and 8, the pulp molded plate 11 is formed as a strip-shaped pulp molded plate 111, i.e., the strip-shaped pulp molded plate 111 has a long strip-shaped plate structure, and the annular body 1 is formed by arranging a plurality of strip-shaped pulp molded plates 111 in the circumferential direction X to form a ring shape, and the adjacent ends of two adjacent strip-shaped pulp molded plates 111 are spliced. That is, a plurality of strip-shaped pulp molded plates 111 are arranged in sequence in the circumferential direction X of the annular body 1, a splicing seam 12 is formed between every two strip-shaped pulp molded plates 111, and the strip-shaped pulp molded plates 111 on both sides of the splicing seam 12 are spliced at the splicing seam 12. For example, one end of the two ends of each strip-shaped pulp molded plate 111 in the length direction is a first end 111a, and the other end is a second end 111b. The first end 111a of one strip-shaped pulp molded plate 111 is spliced with the second end 111b of another strip-shaped pulp molded plate 111 to form a splicing seam 12.

[0069] Thus, the pulp molded plate 11 has a simple structure and is easy to manufacture. The pulp molded connecting piece 30 is formed by splicing a plurality of strip-shaped pulp molded plates 111, so that the splicing times are reduced, the splicing efficiency is improved, and the annular body 1 has only one splicing seam 12, so that the probability of the annular body 1 being cracked from the splicing seam 12 is reduced, and the structural stability of the annular body 1 is improved.

[0070] For example, in production, the connecting structure 2 can be integrally formed on at least one strip-shaped pulp molding plate 111, and then the plurality of strip-shaped pulp molding plates 111 are arranged in a long strip shape along the length direction of each strip-shaped pulp molding plate 111, and are spliced into long strip-shaped spliced plates two by two, and then the long strip-shaped spliced plates are bent to form a ring shape, and the first end and the second end in the length direction of the long strip-shaped spliced plates are spliced to obtain the ring-shaped body 1. Alternatively, for example, in production, the connecting structure 2 can be integrally formed on at least one strip-shaped pulp molding plate 111, and if the strip-shaped pulp molding plate 111 is an arc-shaped plate, the arc-shaped plates are directly spliced two by two to combine into a ring-shaped ring-shaped body 1, and if the strip-shaped pulp molding plate 111 is a flat plate, the strip-shaped pulp molding plate 111 is first bent to form an arc-shaped plate, and then the arc-shaped plates are spliced two by two to combine into a ring-shaped ring-shaped body 1.

[0071] In summary, the pulp molding connecting piece 30 has at least one splicing seam 12, and the portions of the pulp molding connecting piece 30 located on both sides of the splicing seam 12 are spliced at the splicing seam 12. The at least one splicing seam 12 can extend along a straight line, an oblique line, a curved line, or the like, and the splicing seam 12 penetrates both ends in the axial direction Z of the pulp molding connecting piece 30. In this way, when the pulp molding connecting piece 30 is disassembled along the splicing seam 12, the portions on both sides of the splicing seam 12 are separated, so that the ring-shaped body 1 can be unfolded into a non-ring shape, thereby facilitating the manufacturing of the pulp molding connecting piece 30.

[0072] Of course, the present application is not limited thereto, and in other embodiments of the present application, the pulp molding plate 11 can also be configured in other shapes, such as a square, a trapezoid, a rhombus, a parallelogram, a triangle, a circle, a special shape, and the like, as long as the shapes can be mutually engaged to form a ring shape.

[0073] In embodiments of the present application, the splicing manner of the pulp molding plate 11 constituting the ring-shaped body 1 is not limited, that is, the connecting manner of the ring-shaped body 1 at the splicing seam 12 is not limited. For example, the splicing manner can be lap joint bonding between the first end and the second end of the pulp molding plate 11, thereby simplifying the manufacturing of the pulp molding plate 11. For another example, the splicing can also be achieved through the integrally formed buckling structure 3 on the pulp molding plate 11, thereby facilitating the splicing efficiency. For another example, the pulp molding plate 11 can be connected through an additional connecting piece, and the like.

[0074] In some embodiments of the present application, as shown in FIGS. 1 and 2, the splicing position of the ring-shaped body 1 forms a splicing seam 12, the ring-shaped body 1 is integrally formed with a buckling structure 3, the buckling structure 3 includes a first buckling structure 3a and a second buckling structure 3b, and the ring-shaped body 1 is spliced at the splicing seam 12 through the cooperation of the first buckling structure 3a and the second buckling structure 3b. Thus, the ring-shaped body 1 can be spliced at the splicing seam 12 through the buckling structure 3.

[0075] Thus, the splicing is realized by the buckle structure 3 provided by the ring body 1 itself, so as to facilitate the splicing operation. Moreover, the connecting member is not needed to be introduced to be fixedly connected at the splicing joint 12 of the ring body 1, so as to simplify the structure and reduce the use of materials. Moreover, compared with the lap joint bonding between the end portions of the pulp molded plate 11, the bonding process can be omitted.

[0076] For example, in combination with FIGS. 1 and 2, when the ring body 1 is formed by bending a strip-shaped pulp molded plate 111 into a ring shape and the first end and the second end in the length direction of the strip-shaped pulp molded plate 111 are spliced, the first buckle structure 3a can be arranged on one of the two ends in the length direction of the strip-shaped pulp molded plate 111, and the second buckle structure 3b can be arranged on the other end. The first end and the second end in the length direction of the strip-shaped pulp molded plate 111 are spliced by the cooperation of the first buckle structure 3a and the second buckle structure 3a.

[0077] For another example, in combination with FIGS. 7 and 8, when the ring body 1 is formed by arranging a plurality of strip-shaped pulp molded plates 111 in a circumferential direction to form a ring shape, and the adjacent ends of the two adjacent strip-shaped pulp molded plates 111 are spliced, the first buckle structure 3a can be arranged on one of the two ends in the length direction of each strip-shaped pulp molded plate 111, and the second buckle structure 3b can be arranged on the other end. The first buckle structure 3a of one strip-shaped pulp molded plate 111 cooperates with the second buckle structure 3b of the circumferentially adjacent strip-shaped pulp molded plate 111 to realize splicing.

[0078] For example, in combination with FIGS. 7 and 8, the first buckle structure 3a is a buckle plate 31, and the second buckle structure 3b is a buckle groove 32. The buckle plate 31 and the buckle groove 32 are matched in shape, and the buckle plate 31 is filled in the buckle groove 32, so that the pulp molded plate 11 is not lap-spliced at the splicing joint 12, and the buckle groove 32 is configured to limit the buckle plate 31 from being pulled out of the buckle groove 32 along the circumferential direction of the ring body 1.

[0079] In combination with FIG. 9, the two ends of the buckle groove 32 along the circumferential direction X of the ring body 1 are respectively a closed end 32a and an open end 32b. The open end 32b is located on the side away from the center position of the length direction of the strip-shaped pulp molded plate 111 of the closed end 32a. At this time, the open end 32b of the buckle groove 32 can just avoid the buckle plate 31, and the buckle plate 31 can just be filled in the buckle groove 32, so that the pulp molded plate 11 can be lap-spliced at the splicing joint 12.

[0080] Thus, by setting the fastening structure 3 to include the fastening plate 31 and the fastening groove 32, the paper pulp molded plate 11 is implemented to be non-overlappingly spliced at the joint 12, so that when the paper pulp molded plate 11 is configured as an equal-thickness strip (ignoring the connecting structure 2), the enclosed annular body 1 can be relatively uniform in wall thickness in the entire circumferential range, thereby facilitating the manufacture of the paper pulp molded plate 11. Moreover, by configuring the shape of the fastening groove 32 to be able to limit the fastening plate 31 from being pulled out of the fastening groove 32 along the circumferential direction of the annular body 1, a self-locking connection can be achieved.

[0081] Exemplarily, in combination with FIG. 9, the fastening groove 32 is a T-shaped groove 321, and the fastening plate 31 is a T-shaped plate 311, the T-shaped plate 311 is filled in the T-shaped groove 321, and the T-shaped plate 311 cannot be pulled out of the T-shaped groove 321 along the circumferential direction X of the annular body 1, so that the structure of the fastening groove 32 and the fastening plate 31 is simple, facilitating manufacturing and assembly. For example, the T-shaped groove 321 can include a first groove segment 3211 and a second groove segment 3212 arranged in this order along the direction from the closed end 32a to the open end 32b, the length direction of the first groove segment 3211 extends along the axial direction Z of the annular body 1, and one end of the second groove segment 3212 extending along the circumferential direction X of the annular body 1 is connected to the center of the first groove segment 3211 to combine with the first groove segment 3211 to form the T-shaped groove 321, and the other end of the first groove segment 3211 away from the second groove segment 3212 is the closed end 32a of the fastening groove 32, and the other end of the second groove segment 3212 away from the first groove segment 3211 is the open end 32b of the fastening groove 32, so that the fastening plate 31 can be limited to be pulled out of the fastening groove 32 along the direction from the closed end 32a to the open end 32b of the fastening groove 32.

[0082] Exemplarily, in combination with FIG. 10, the fastening groove 32 is a dovetail groove 322, and the fastening plate 31 is a dovetail plate 312, the dovetail plate 312 is filled in the dovetail groove 322, and the dovetail plate 312 cannot be pulled out of the dovetail groove 322 along the circumferential direction of the annular body 1, so that the structure of the fastening groove 32 and the fastening plate 31 is simple, facilitating manufacturing and assembly. For example, the dovetail groove 322 is trapezoidal, the height direction of the dovetail groove 322 is consistent with the circumferential direction X of the annular body 1, the axial direction Z of the annular body 1 is the width direction of the dovetail groove 322, and the width W of the dovetail groove 322 gradually decreases from the closed end 32a to the open end 32b, so that the fastening plate 31 can be limited to be pulled out of the fastening groove 32 along the direction from the closed end 32a to the open end 32b of the fastening groove 32.

[0083] In some embodiments of the present application, as shown in Figs. 3-6, the connecting structure 2 is formed as a threaded matching structure 21 adapted to match with a threaded structure. For example, the threaded structure can be the internal thread or the external thread as described above. In this way, the connection between the container lid 10 and the mouth ring 20a of the container 20 can be achieved by rotating the container lid 10, thereby reducing the difficulty of connecting the container lid 10 with the container 20 and facilitating the operation of connecting or dismounting the container lid 10 from the container 20.

[0084] Exemplarily, as shown in Figs. 1 and 2, the threaded matching structure 21 comprises a plurality of strip-shaped protrusions 211 distributed at intervals along the same helix. That is, the threaded matching structure 21 can comprise a protruding rib extending along a helix, and the protruding rib has a plurality of discontinuities to divide the protruding rib into a plurality of strip-shaped protrusions 211 arranged at intervals along the extension direction of the helix. In this way, the threaded matching structure 21 is not a continuous rib extending along a helix, but an intermittent rib extending along a helix, thereby saving the material of the connecting structure 2 and facilitating the shape stability of the ring body 1.

[0085] Exemplarily, as shown in Figs. 11 and 12, the threaded matching structure 21 comprises a plurality of semispherical protrusions 212 distributed at intervals along the same helix. In this way, the threaded matching structure 21 is not a continuous rib extending along a helix, but a plurality of semispherical protrusions 212 arranged at intervals along the extension direction of the helix, thereby saving the material of the connecting structure 2 and facilitating the shape stability of the ring body 1. Moreover, the semispherical protrusions 212 are semispherical in shape, which is conducive to smooth matching with the threaded structure and improves the convenience of operation.

[0086] Exemplarily, as shown in Fig. 13, the threaded matching structure 21 comprises a plurality of strip-shaped protrusions 211 and a plurality of semispherical protrusions 212 distributed at intervals along the same helix. For example, a plurality of semispherical protrusions 212 are arranged between two adjacent strip-shaped protrusions 211 along the extension direction of the helix, and a plurality of strip-shaped protrusions 211 are arranged between two adjacent semispherical protrusions 212 along the extension direction of the helix. In this way, the material of the connecting structure 2 can be saved, and the shape stability of the ring body 1 can be improved.

[0087] Exemplarily, the threaded matching structure 21 can also be configured as a continuous rib extending along a helix, thereby facilitating the manufacture and improving the tightness of the matching between the threaded structure and the threaded matching structure 21.

[0088] In some embodiments of the present application, the connecting structure 2 is arranged on one of the inner circumferential surface and the outer circumferential surface of the annular body 1, and the other of the inner circumferential surface and the outer circumferential surface of the annular body 1 is a smooth curved surface. For example, in combination with FIG. 11 and FIG. 14, the connecting structure 2 is arranged on the inner circumferential surface of the annular body 1, and the outer circumferential surface of the annular body 1 is a smooth curved surface. For another example, in combination with FIG. 1 and FIG. 7, the connecting structure 2 is arranged on the outer circumferential surface of the annular body 1, and the inner circumferential surface of the annular body 1 is a smooth curved surface. In this way, the annular body 1 can be mounted on a carrier (for example, the container 20 or the container cover 10) by using a smooth curved surface, which is conducive to increasing the connecting area of the pulp molded connecting piece 30 and the carrier and improving the connecting reliability of the pulp molded connecting piece 30 and the carrier.

[0089] For example, when the pulp molded plate 11 includes a strip-shaped pulp molded plate 111, and the annular body 1 is surrounded by at least one strip-shaped pulp molded plate 111 in a ring shape, the connecting structure 2 is arranged on one side surface in the thickness direction of the at least one strip-shaped pulp molded plate 111, that is, the single side of the strip-shaped pulp molded plate 111 has the connecting structure 2, so that the connecting structure 2 can be arranged on one of the inner circumferential surface and the outer circumferential surface of the annular body 1, and the other of the inner circumferential surface and the outer circumferential surface of the annular body 1 can be a smooth curved surface. In this way, the manufacturing of the pulp molded plate 11 is facilitated, and the material is saved, and the cost is reduced.

[0090] The pulp molded material has the characteristics of green environmental protection, but in the manufacturing process of the pulp molded container cover or the pulp molded container, it is difficult to integrally form the connecting structure such as threads on the pulp molded container cover or the pulp molded container by a pulp molding process; if a threaded plastic ring is used instead, although the threads on the circumferential wall surface of the threaded plastic ring can be integrally formed by an injection molding process, the threaded plastic ring is made of plastic material, which is not conducive to environmental protection.

[0091] In the embodiments of the present application, since the pulp molded connecting piece 30 is formed by splicing the pulp molded plates 11 to form the annular body 1, and the connecting structure 2 is formed on the circumferential wall surface of the annular body 1, the connecting structure 2 can be integrally formed on the non-ring-shaped pulp molded plate 11 by a pulp molding process first, and then the annular body 1 is obtained by splicing the pulp molded plates 11, so that the manufacturing of the pulp molded connecting piece 30 is easy to implement. Moreover, the pulp molded connecting piece 30 is made of pulp molded material, which is green and environmentally friendly.
