DETAILED DESCRIPTION

[0040] In order to further explain the technical scheme of the utility model, the utility model is described in detail below through specific embodiments.

[0041] Below, referring to the drawings, the embodiment of the pulp molded connecting piece 30 of the utility model is as follows.

[0042] As Figure 1 and Figure 2As shown, the pulp-molded connecting piece 30 is spliced by the pulp-molded plates 11 to form the ring body 1, wherein "splicing" refers to both "encircling splicing" and "connecting", the pulp-molded plate 11 itself is a non-ring structure, and the ring body 1 is formed by encircling splicing and connecting of the pulp-molded plates 11, the ring body 1 is formed into a ring shape by "encircling splicing" of the pulp-molded plates 11, and the ring shape is maintained by "connecting" of the pulp-molded plates 11, and the ring body 1 cannot be automatically unfolded into a non-ring shape.

[0043] For example, the connecting in the splicing can be achieved by bonding between the ends of different pulp-molded plates 11, or can be achieved by bonding between the two ends of the same pulp-molded plate 11 itself; for another example, the connecting in the splicing can be achieved by clamping splicing between the ends of different pulp-molded plates 11, or can be achieved by clamping between the two ends of the same pulp-molded plate 11 itself.

[0044] The connecting structure 2 is formed on the peripheral wall surface of the ring body 1, that is, the connecting structure 2 is formed on one of the inner peripheral surface and the outer peripheral surface of the ring body 1, in combination with Figures 3-6 The connecting structure 2 is used to connect the container cover 10 and the container 20.

[0045] For example, in combination with Figure 1 and Figure 2 When the pulp-molded connecting piece 30 is spliced by one pulp-molded plate 11 to form the ring body 1, 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 to form the ring body 1, so that the connecting structure 2 is formed on the peripheral wall surface of the spliced ring body 1.

[0046] For example, in combination with Figure 7 When the pulp-molded connecting piece 30 is spliced by a plurality of pulp-molded plates 11 to form the ring body 1, the connecting structure 2 can be integrally formed on at least one of the pulp-molded plates 11 first, and then the plurality of pulp-molded plates 11 are spliced to form the ring body 1, so that the connecting structure 2 is formed on the peripheral wall surface of the spliced ring body 1.

[0047] In this way, the connecting structure 2 can be integrally formed on the non-ring pulp-molded plate 11 by the pulp-molded forming process first, 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-molded material, which is green and environmentally friendly.

[0048] When the pulp molded connecting piece 30 is used for the container 20, the pulp molded connecting piece 30 can be arranged around the mouth ring 20a of the container 20, and the connecting structure 2 is shaped to be suitable for connection with the matching structure inside the container cover 10.

[0049] The specific form of the connecting structure 2 is not limited, as long as it can realize the connection of the container 20 and the container cover 10. For example, in combination with Figure 3 and Figure 4 When the pulp molded connecting piece 30 is used for the container cover 10, the connecting structure 2 is shaped to be suitable for connection with the matching structure on the mouth ring 20a of the container 20, Figure 3 The container 20 can adopt a general market conventional container 20; for example, in combination with Figure 5 and Figure 6 When the pulp molded connecting piece 30 is used for the container 20, the pulp molded connecting piece 30 can be arranged around the mouth ring 20a of the container 20, and the connecting structure 2 is shaped to be suitable for connection with the matching structure inside the container cover 10.

[0050] The type of the container 20 is not limited, for example, the container 20 can be a bottle, a jar, a pot, etc. The opening position of the container 20 is the mouth ring 20a of the container 20, and the container cover 10 is arranged on the mouth ring 20a to close the opening position of the container 20. The type of the container cover 10 is not limited, as long as it is matched with the form of the mouth ring 20a of the container 20.

[0051] Exemplarily, the container 20 is a bottle, the container cover 10 is a bottle cap, the bottle mouth of the bottle is the mouth ring 20a, the outer periphery of the mouth ring 20a has an external thread as a matching structure, and the pulp molded connecting piece 30 is arranged in the bottle cap and around the inner periphery of the bottle cap. The connecting structure 2 is arranged as an internal thread suitable for cooperation with the external thread.

[0052] Exemplarily, the container 20 is a bottle, the container cover 10 is a bottle cap, the bottle mouth of the bottle is the mouth ring 20a, the outer periphery of the mouth ring 20a has an external thread as a matching structure, and the pulp molded connecting piece 30 is arranged in the bottle cap and around the inner periphery of the bottle cap. The connecting structure 2 is arranged as an internal thread suitable for cooperation with the external thread.

[0053] Exemplarily, the container 20 is a bottle, the bottle mouth of the bottle is the mouth ring 20a, the container cover 10 is a bottle cap, and the inner periphery of the bottle cap has an internal thread as a matching structure. The pulp molded connecting piece 30 is arranged on the bottle mouth of the bottle and around the outer periphery of the bottle mouth, and the connecting structure 2 is arranged as an external thread suitable for cooperation with the internal thread.

[0054] Exemplarily, the container 20 is a bottle, the bottle mouth of the bottle is the mouth ring 20a, the container cover 10 is a bottle cap, the inner periphery of the bottle cap has an inner buckle as the matching structure, the pulp molded connecting piece 30 is arranged on the bottle mouth of the bottle and is arranged around the outer periphery of the bottle mouth, and the connecting structure 2 is arranged as an outer buckle matched with the inner buckle.

[0055] Therefore, according to the pulp molded connecting piece 30 in the embodiment of the utility model, since the pulp molded connecting piece 30 is formed into the annular body 1 by splicing the pulp molded plates 11, 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 plates 11, so that the annular body 1 is conveniently installed 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.

[0056] In some embodiments of the utility model, as shown in Figure 1 and Figure 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 formed by bending the 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. One of the two ends in the length direction of the strip-shaped pulp molded plate 111 is the first end 111a, and the other is the second end 111b. The splicing of the first end 111a and the second end 111b 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.

[0057] Therefore, the structure of the pulp molded plate 11 is simple and convenient to manufacture, and the pulp molded connecting piece 30 is formed by splicing only one strip-shaped pulp molded plate 11, so that the splicing frequency can be 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.

[0058] For example, during 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, then the strip-shaped pulp molded plate 111 with the connecting structure 2 is bent into a ring shape, and then the first end and the second end in the length direction of the strip-shaped pulp molded plate 111 are spliced to obtain the annular body 1.

[0059] In some embodiments of the utility model, as shown in Figure 7 and Figure 8As shown, the pulp molding plate 11 is formed as a strip-shaped pulp molding plate 111, i.e., the strip-shaped pulp molding plate 111 is a long strip-shaped plate structure, and the annular body 1 is formed by arranging a plurality of strip-shaped pulp molding plates 111 along the circumferential direction X to form a ring shape, and the adjacent ends of two adjacent strip-shaped pulp molding plates 111 are spliced. That is, a plurality of strip-shaped pulp molding plates 111 are arranged in sequence along the circumferential direction X of the annular body 1, and a splicing joint 12 is formed between every two strip-shaped pulp molding plates 111, and the strip-shaped pulp molding plates 111 on both sides of the splicing joint 12 are spliced at the splicing joint 12. For example, one end of the two ends in the length direction of each strip-shaped pulp molding plate 111 is a leading end 111a, and the other end is a trailing end 111b, and the leading end 111a of one strip-shaped pulp molding plate 111 is spliced with the trailing end 111b of another strip-shaped pulp molding plate 111 to form a splicing joint 12.

[0060] Therefore, the pulp molding plate 11 has a simple structure, is easy to manufacture, and the pulp molding connector 30 is only formed by arranging a plurality of strip-shaped pulp molding plates 111 along the circumferential direction to form a ring shape, the number of splicing joints 12 is consistent with the number of strip-shaped pulp molding plates 111, so that the splicing operation is also relatively simple and easy to operate.

[0061] For example, during production, the connecting structure 2 can be integrally formed on at least one strip-shaped pulp molding plate 111, and then a plurality of strip-shaped pulp molding plates 111 are arranged in sequence along the length direction of each strip-shaped pulp molding plate 111 to form a long strip shape, and two-by-two splicing is performed to form a long strip-shaped splicing plate, and then the long strip-shaped splicing plate is bent to form a ring shape, and the leading and trailing ends in the length direction of the long strip-shaped splicing plate are spliced to obtain the annular body 1. Alternatively, for example, during 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, two-by-two splicing of a plurality of arc-shaped plates can be directly performed to combine the arc-shaped plates into an annular body 1, and if the strip-shaped pulp molding plate 111 is a flat plate, bending of each strip-shaped pulp molding plate 111 can be performed first to form an arc-shaped plate, and then two-by-two splicing of a plurality of arc-shaped plates can be performed to combine the arc-shaped plates into an annular body 1.

[0062] In summary, the pulp molding connector 30 has at least one splicing joint 12, and the portions of the pulp molding connector 30 on both sides of the splicing joint 12 are spliced at the splicing joint 12, the at least one splicing joint 12 can extend along a straight line, or a broken line, or a curve, etc., and the splicing joint 12 penetrates both ends in the axial direction Z of the pulp molding connector 30, so that when the pulp molding connector 30 is disassembled along the splicing joint 12, the portions on both sides of the splicing joint 12 are separated, so that the annular body 1 can be unfolded into a non-ring shape, thereby facilitating the manufacture of the pulp molding connector 30.

[0063] Of course, the utility model is not limited to this, in other embodiments of the utility model, the paper pulp molded plate 11 can also be configured in other shapes, such as square, trapezoidal, rhombic, parallelogram, triangular, circular, special-shaped and the like, as long as the shapes can be mutually engaged to form a ring.

[0064] In the embodiments of the utility model, the splicing mode of the paper pulp molded plate 11 constituting the annular body 1 is not limited, that is, the connecting mode of the annular body 1 at the joint 12 is not limited, for example, the lap joint and bonding between the head and tail ends of the paper pulp molded plate 11, so that the manufacturing of the paper pulp molded plate 11 can be simplified; for example, the integrated buckle structure 3 can also be formed on the paper pulp molded plate 11, and the splicing is realized through the buckle structure 3, so that the splicing efficiency can be improved; for example, the paper pulp molded plate 11 can also be connected through the additionally arranged connecting piece, and the like.

[0065] In some embodiments of the utility model, as shown in Figure 1 and Figure 2 The splicing position of the annular body 1 forms the joint 12, the integrated buckle structure 3 is formed on the annular body 1, the buckle structure 3 includes the first buckle structure 3a and the second buckle structure 3b, and the annular body 1 is spliced at the joint 12 through the cooperation of the first buckle structure 3a and the second buckle structure 3b, so that the annular body 1 can be spliced at the joint 12 through the buckle structure 3.

[0066] Therefore, the splicing is realized through the buckle structure 3 possessed by the annular body 1 itself, so that the splicing operation is facilitated. Moreover, the connecting piece does not need to be introduced to be fixedly connected at the joint 12 of the annular body 1, so that the structure can be simplified, and the use of materials can be reduced. Moreover, compared with the lap joint and bonding between the ends of the paper pulp molded plate 11, the bonding process can be omitted.

[0067] For example, in combination with Figure 1 and Figure 2 When the annular body 1 is formed by bending a strip-shaped paper pulp molded plate 111 into a ring shape, and the head and tail ends in the length direction of the strip-shaped paper 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 paper pulp molded plate 111, and the second buckle structure 3b is arranged on the other end, and the head and tail ends in the length direction of the strip-shaped paper pulp molded plate 111 are spliced through the cooperation of the first buckle structure 3a and the second buckle structure 3a.

[0068] For example, in combination with Figure 7 and Figure 8When the ring-shaped body 1 is formed by arranging a plurality of strip-shaped pulp molding plates 111 in a circumferential direction to form a ring, and the adjacent ends of two adjacent strip-shaped pulp molding plates 111 are spliced, a first buckling structure 3a can be arranged on one of the two ends of the length direction of each strip-shaped pulp molding plate 111, and a second buckling structure 3b can be arranged on the other end. The first buckling structure 3a of one strip-shaped pulp molding plate 111 is matched with the second buckling structure 3b of the circumferentially adjacent strip-shaped pulp molding plate 111 to achieve splicing.

[0069] Exemplarily, referring to Figure 7 and Figure 8 , the first buckling structure 3a is a buckling plate 31, and the second buckling structure 3b is a buckling groove 32. The buckling plate 31 is matched with the buckling groove 32 in shape, and the buckling plate 31 is filled in the buckling groove 32, so that the pulp molding plate 11 is spliced without lap joint at the joint 12, and the buckling groove 32 is configured to limit the buckling plate 31 from being pulled out of the buckling groove 32 along the circumferential direction X of the ring-shaped body 1.

[0070] In combination with Figure 9 , the two ends of the buckling groove 32 along the circumferential direction X of the ring-shaped 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 molding plate 111 of the closed end 32a. At this time, the open end 32b of the buckling groove 32 can just avoid the buckling plate 31, and the buckling plate 31 can just be filled in the buckling groove 32, so that the pulp molding plate 11 can be spliced without lap joint at the joint 12.

[0071] Therefore, by arranging the buckling structure 3 to include the buckling plate 31 and the buckling groove 32, the pulp molding plate 11 is spliced without lap joint at the joint 12, so that when the pulp molding plate 11 is configured as an equal-thickness strip (ignoring the connecting structure 2), the ring-shaped body 1 formed thereby can have a relatively uniform wall thickness in the entire circumferential range, thereby facilitating the manufacture of the pulp molding plate 11. Moreover, by configuring the shape of the buckling groove 32 to be able to limit the buckling plate 31 from being pulled out of the buckling groove 32 along the circumferential direction of the ring-shaped body 1, a self-locking connection can be achieved.

[0072] Exemplarily, in combination with Figure 9, the buckling groove 32 is a T-shaped groove 321, and the buckling 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 taken out of the T-shaped groove 321 along the circumferential direction X of the annular body 1, so that the structure of the buckling groove 32 and the buckling plate 31 is simple, convenient to manufacture, and convenient to assemble. For example, the T-shaped groove 321 can include a first groove section 3211 and a second groove section 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 section 3211 extends along the axial direction Z of the annular body 1, one end of the second groove section 3212 extending along the circumferential direction X of the annular body 1 is connected with the center of the first groove section 3211 to combine with the first groove section 3211 to form the T-shaped groove 321, and the other end of the first groove section 3211 away from the second groove section 3212 is the closed end 32a of the buckling groove 32, and the other end of the second groove section 3212 away from the first groove section 3211 is the open end 32b of the buckling groove 32, so that the buckling plate 31 can be prevented from being taken out of the buckling groove 32 along the direction from the closed end 32a to the open end 32b of the buckling groove 32.

[0073] For example, as shown in Figure 10 , the buckling groove 32 is a dovetail groove 322, and the buckling 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 taken out of the dovetail groove 322 along the circumferential direction of the annular body 1, so that the structure of the buckling groove 32 and the buckling plate 31 is simple, convenient to manufacture, and convenient to assemble. 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 buckling plate 31 can be prevented from being taken out of the buckling groove 32 along the direction from the closed end 32a to the open end 32b of the buckling groove 32.

[0074] In some embodiments of the present application, as shown in Figures 3-6 , the connecting structure 2 is formed as a threaded matching structure 21 suitable for screwing with the threaded structure. For example, the threaded structure can be the internal thread or the external thread described above. In this way, the connection between the container cover 10 and the mouth ring 20a of the container 20 can be achieved by rotating the container cover 10, thereby reducing the difficulty of connecting the container cover 10 with the container 20 and facilitating the operation of connecting or dismounting the container cover 10 to the container 20.

[0075] For example, as shown in Figure 1 and Figure 2As shown, the threaded engagement structure 21 includes a plurality of strip-shaped protrusions 211 spaced apart along the same helix. That is, the threaded engagement structure 21 may include a rib extending along a helix, the rib having multiple breaks to divide it into a plurality of strip-shaped protrusions 211 spaced apart along the extension direction of the helix. Therefore, the threaded engagement structure 21 is not a continuous rib extending along a helix, but rather a discontinuous rib extending along a helix, thereby saving material for the connecting structure 2 and improving the shape stability of the annular body 1.

[0076] For example, such as Figure 11 and Figure 12 As shown, the threaded engagement structure 21 includes multiple hemispherical protrusions 212 spaced apart along the same helix. Therefore, the threaded engagement structure 21 is not a continuous rib extending along the helix, but rather multiple hemispherical protrusions 212 spaced apart along the extension direction of a helix. This saves material in the connecting structure 2 and improves the shape stability of the annular body 1. Furthermore, the hemispherical protrusions 212 are hemispherical in shape, which facilitates smooth engagement with the threaded structure and improves operational convenience.

[0077] For example, such as Figure 13 As shown, the threaded mating structure 21 includes multiple strip-shaped protrusions 211 and multiple hemispherical protrusions 212 spaced apart along the same helix. For example, several hemispherical protrusions 212 are provided between two adjacent strip-shaped protrusions 211 along the extension direction of the helix, and several strip-shaped protrusions 211 are provided between two adjacent hemispherical protrusions 212 along the extension direction of the helix. This saves material in the connecting structure 2 and improves the shape stability of the annular body 1.

[0078] For example, the threaded mating structure 21 can also be constructed as a continuous rib extending along a helix, which facilitates manufacturing and improves the tightness of the fit between the threaded structure and the threaded mating structure 21.

[0079] In some embodiments of this utility model, the connecting structure 2 is disposed on one of the inner and outer circumferential surfaces of the annular body 1, and the other of the inner and outer circumferential surfaces of the annular body 1 is a smooth curved surface. For example, combined with Figure 11 and Figure 14 The connecting structure 2 is located 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 example, combining... Figure 1 and Figure 7 The connecting structure 2 is located 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. As a result, the annular body 1 can be installed on a carrier (such as a container 20 or a container cover 10) using its smooth curved surface, which helps to increase the connection area between the pulp molding connector 30 and the carrier and improve the connection reliability between the pulp molding connector 30 and the carrier.

[0080] Exemplarily, when the pulp molded plate 11 comprises a strip-shaped pulp molded plate 111, the ring-shaped 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 of the at least one strip-shaped pulp molded plate 111 in the thickness direction, 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 peripheral surface and the outer peripheral surface of the ring-shaped body 1, and the other of the inner peripheral surface and the outer peripheral surface of the ring-shaped body 1 can be a smooth curved surface. Thus, the manufacture of the pulp molded plate 11 is facilitated, and the material is saved, and the cost is reduced.

[0081] 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 structure such as thread for connection on the pulp molded container cover or the pulp molded container through the pulp molding forming process; if a threaded plastic ring is used instead, although the thread on the circumferential wall surface of the threaded plastic ring can be integrally formed through the injection molding process, the threaded plastic ring is made of plastic material, which is not conducive to environmental protection.

[0082] In the embodiments of the present application, the pulp molded connecting piece 30 is spliced to form the ring-shaped body 1 through the pulp molded plate 11, and the connecting structure 2 is formed on the circumferential wall surface of the ring-shaped body 1, so that the connecting structure 2 can be integrally formed on the non-ring-shaped pulp molded plate 11 through the pulp molding forming process, and then the ring-shaped body 1 is obtained by splicing the pulp molded plate 11, so that the manufacture of the pulp molded connecting piece 30 is easy to realize. Moreover, the pulp molded connecting piece 30 is made of pulp molded material, which is green and environmentally friendly.
