Abstract
The utility model provides a container that combination is moulded to paper, including the paper container body and plastics oral area, the paper container body has the link of being connected with the plastics bottleneck, the paper container body is as an organic whole through moulding plastics with the plastics oral area, and the plastics oral area is with the link cladding of the paper container body when moulding plastics. The paper container body and the plastic opening part are combined into a whole through one-time injection molding, the process steps are few, the strength is firm, the bonding force is uniform, the injection molding bonding area can be flexibly adjusted according to factors such as the thickness of paper, the capacity of the container and the like, the inner side and the outer side of the container can be combined through injection molding, and the bonding strength is further improved.
Description
Technical Field
The utility model relates to a container that combines is moulded to paper.
Background
For paper-plastic combined containers such as bottles and boxes, most of the containers are provided with a plastic part at the opening and a box body or a paper part at the bottle body in advance, and then are firmly bonded by an adhesive. Moreover, if the volume of the container is larger, the bonding surface needs to be increased, but the uniform bonding is difficult, and the quality hidden trouble is caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a container that combines is moulded to paper of sound construction, environmental protection is provided. Therefore, the utility model adopts the following technical scheme:
the utility model provides a container that combination is moulded to paper, includes the paper container body and plastics oral area, and the paper container body has the link of being connected with the plastics bottleneck, its characterized in that the paper container body is as an organic whole through moulding plastics with the plastics oral area, and the plastics oral area is when moulding plastics with the link cladding of the paper container body.
Furthermore, the coating part of the plastic opening part comprises an injection molding coating part positioned on the inner side of the paper container body and an injection molding coating part positioned on the outer side of the paper container body, wherein the combination area of the inner injection molding coating part and the connecting end of the paper container body is larger than that of the outer injection molding coating part and the connecting end of the paper container body.
Furthermore, the injection molding cladding part at the inner side of the paper container body and the injection molding cladding part at the outer side of the paper container body are in transition shapes which are thickened parts and gradually thinned at the connecting port of the paper container body.
Because adopt the technical scheme of the utility model, the paper container body combines as an organic whole through once moulding plastics with the plastics oral area, and the technology step is few, and intensity is firm, and the cohesion is even, can be according to factors such as the thickness of paper, the capacity of container and nimble adjustment the combination area of moulding plastics, and can all mould plastics the combination inside and outside, further improve joint strength.

Fig. 2 is a partial schematic view of an embodiment provided by the present invention.
Fig. 3 is an enlarged view of a portion a of fig. 1.
Detailed Description
Referring to the attached drawings, the present embodiment takes a paper-plastic combined bottle as an example, and includes a paper container body 1 and a plastic bottle mouth 2, the paper container body 1 has a connecting end 11 connected with the plastic bottle mouth, the paper container body 1 and the plastic bottle mouth 2 are connected into a whole through injection molding, and the plastic bottle mouth 2 covers the connecting end of the paper container body 1 during injection molding.
The coating part of the plastic bottle mouth 2 comprises an injection molding coating part 21 positioned on the inner side of the paper container body and an injection molding coating part 22 positioned on the outer side of the paper container body, wherein the combination area of the inner injection molding coating part 21 and the connecting end 11 of the paper container body is larger than that of the outer injection molding coating part 22 and the connecting end 11 of the paper container body. Through the internal and external cladding, the injection molding connection manufacturing of the paper container body 1 and the plastic bottle mouth 2 can be facilitated, the internal and external cladding depth can be flexibly adjusted, and an injection mold is optimized.
The injection-molded cover part 21 positioned on the inner side of the paper container body and the injection-molded cover part 22 positioned on the outer side of the paper container body are both in a transition shape that thickened parts 211 and 221 are arranged at the connecting port of the paper container body and gradually thinned parts 212 and 222, so that the strength is improved, and the stress state of the injection-molded combination part is optimized.
The above description is only for the specific embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any person skilled in the art is in the field of the present invention, and all the changes or modifications are covered in the protection scope of the present invention.
