[ background of the invention ]
Many people, especially office workers, almost daily buy a cup of coffee from a brand chain supermarket or fast food restaurant and develop a day's job, and no coffee is drunk, and seem to be reluctant to take up the job. If the consumer does not prepare the accompanying cup, the supermarkets or fast food restaurants can put the cup on the consumer, and the consumer can carry and move the cup and drink the cup at any time by holding the cup. "out-wrap paper cups" are also often referred to as "disposable paper cups," "disposable hand cups," or "disposable paper cups," and the like. At present, a conventional paper cup with an external cup is generally composed of a cup body and a cup cover, wherein the cup body is used for containing liquid beverage, and the cup cover is covered on the cup opening of the cup body to prevent the liquid beverage in the cup body from overflowing.
Regarding the cup lid commonly used in the market, the cup lid is usually made of PP, PS, PVC and other plastic materials by plastic injection molding, and is generally called as "plastic cup lid". In the current times of rising environmental awareness, disposable plastic cup lids made of plastic materials are used, and thus the environmental awareness is completely deviated from the existing environmental awareness. Furthermore, the conventional plastic cup lid is formed by plastic injection molding, and the moving space required for demolding is limited, so that the use of the finished plastic cup lid product cannot meet the requirement of tightly covering the rim of a paper cup, and the plastic cup lid product is easy to loosen and fall off after being combined with the rim of the paper cup, thereby causing the leakage of beverage and causing the worry of unsafe use for users. In the conventional plastic cup lid, the top surface and the drinking hole are both arranged on the same plane due to the injection molding technology of the plastic mold, so when a user drinks the beverage by tilting the cup body with the mouth on the drinking hole, the liquid flow of the beverage in the cup body is completely flushed to the drinking hole, and if the tilting angle of the cup body is too large, the user can be frightened by the liquid flow of the beverage, and the beverage splashed out by carelessness can be affected, so the use loss caused by the undesirable structure is avoided, and the practical value is improved.
At present, paper-plastic products are developed which are manufactured by mixing paper pulp and/or plant fiber materials as materials and adopting the technologies of pulp absorption moulding and hot press forming, but most of the paper-plastic products are manufactured and used as isolation buffer materials, and the paper-plastic cup covers manufactured and formed by paper-plastic materials are not thought to be manufactured and formed by paper-plastic materials.

[ detailed description ] embodiments
Referring to fig. 1-4, an embodiment of the present invention is a paper-plastic cup lid 1, that is, a paper-plastic cup lid manufactured by a mold slurry-sucking molding and hot-press molding technique, the structure of which has a main annular wall 10 that is formed into a circle, the rear end side of the main annular wall 10 is turned upward to form a rear end arc edge 11, the rear end arc edge 11 is extended and surrounded by two sides forward, and gradually changes into a horizontal side platform 12 after about half of the time, the outer edge and the inner edge of the side platform are both arc lines, the inner edge has a higher curvature than the outer edge (i.e., the inner edge is bent), then the front end of the side platform 12 adopts an inclined protection slope 13 that has a higher inclination and extends into a section, the outer edge and the inner edge of the inclined protection slope 13 are both arc lines, and the inner edge has a higher curvature than the outer edge (i.e., the inner edge is bent), finally the front ends of the two inclined protection slopes 13 are combined together to form a high platform 14, the inner edge of the high platform 14 is connected with the inner edge of, an inner protective wall 141 is vertically arranged in a circular arc tangent mode; the upper row of each part is arranged from small to large in width when viewed from top (as shown in fig. 2), the rear arc edge 11 is the narrowest in width, the first row is gradually wider when extending to two sides, then the side platform 12 is wider than the rear arc edge 11, the second row is the second row, the inclined ramp 13 is wider than the side platform 12, the third row is the third row, and finally the high platform 14 is integrated by extending from two sides, so the high platform 14 is the fourth row in width, at the same time, the rear arc edge 11, the side platform 12, the inclined ramp 13 and the inner edge of the high platform 14 (the inner edge of the high platform 14, i.e. the tangent inner protective wall 141) encircle a circle, so that the plane in the middle of the circle forms a cup top surface 15 with relatively low height, the depth of the cup top surface 15 at the rear arc edge 11 is preferably 2mm, and a micro vent hole 151 is arranged on the cup top surface 15 adjacent to the rear arc edge 11, therefore, the cup top surface 15 is not located at the center of the paper-plastic cup cover 1, but is in a backward offset state as shown in fig. 1 and 2.
The upper surface of the high platform 14 is formed with a slightly concave drinking hole 20 at the center with respect to the arc-shaped outer edge, please refer to fig. 5, a horizontal opening plate 21 is formed on the drinking hole 20, the inner side edge of the opening plate 21 is the top edge of the inner protection wall 141, and is formed into an arc-shaped easy-to-turn edge 211, a raised pushing body 22 is further formed at the center of the opening plate 21, during the manufacturing and forming, the pushing body 22, the opening plate 21 and the high platform 14 are integrally formed, and the connecting edges of the opening plate 21 and the drinking hole 20, except for the easy-to-turn edge 211, are made into a potentially thin easy-to-turn edge 23, that is, the connecting edges of the three edges are all cut to have a thickness less than half to form an easy-to-turn edge 23, and the easy-to-turn edges 23 of the upper and lower two edges as shown in fig. 5 must be cut to reach the easy-to-turn edge 211, as can be seen, the drinking hole 20 is completely covered and not shown by the opening plate 21 and the pushing body 22 when not in use, and the easy-tearing edge 23 is in a hidden-thin connection relation when the drinking hole 20 is not in use; a concave containing cavity 24 is formed on the cup top surface 15 at a distance from the high platform 14, a blocking platform 25 with a raised inclined back is formed behind the containing cavity 24, and the blocking platform 25 is in a shape of enclosing the containing cavity 24 from two sides.
Referring to fig. 6, after the bottom of the main annular wall 10 extends outward for a small distance to form a bottom platform 16, it is bent downward to form a ring of inward-bent covering edge 17, and finally it is expanded outward to form a ring of lifting pieces 18, where it is known that the end of the bottom platform 16 reaching the end of the covering edge 17 forms an inward-facing slightly-bent arc shape, and then the end of the covering edge 17 reaching the end of the lifting pieces 18 forms an outward-facing slightly-bent arc shape.
The paper-plastic cup lid 1 of the embodiment of the present invention must be used with a cup body 30, as shown in fig. 7 and 8, generally, a ring-shaped binding edge 31 is formed on the periphery of the cup body 30 at the cup opening, when the paper-plastic cup lid 1 of the embodiment of the present invention is to be covered on the cup opening of the cup body 30 (certainly, the cup body 30 is filled with a beverage), the paper-plastic cup lid 1 is covered under the state that the coating edge 17 corresponds to the binding edge 31, but because the minimum inner diameter of the coating edge 17 is slightly smaller than the outer diameter of the binding edge 31, the coating edge 17 is blocked by the binding edge 31 and cannot pass through initially, at this time, as long as an operator presses the paper-plastic cup lid 1 close to the symmetrical portion by hand and then presses down with a slight force, the minimum inner diameter of the coating cup lid edge 17 of the paper-plastic cup lid 1 is slightly expanded and goes over the binding edge 31 under the forced pushing pressure, so that the paper-plastic cup lid 1 presses the winding turns one by one, finally, as shown in fig. 7, the wrapping edge 17 completely crosses and wraps the binding edge 31, so as to achieve the effect of tightly and stably covering the paper-plastic cup lid 1 on the cup body 30, and at this time, the paper cup (including the cup body 30, the internal beverage and the paper-plastic cup lid 1) can be moved with the whole "outer paper cup" (i.e. the cup body 30, the internal beverage and the paper-plastic cup lid 1), if the hot beverage is filled in the cup body 30, the generated pressure can be released through the micro ventilation holes 151, so as to avoid overpressure in the cup body 30.
The paper-plastic cup cover 1 of the embodiment of the invention is made by mixing paper pulp and/or plant fiber materials as materials and adopting the technologies of pulp absorption molding and hot press forming, therefore, the elastic deformability in a certain force application range is better than that of a plastic cup cover, when a user presses the paper-plastic cup cover 1 close to a symmetrical part and presses downwards with slight force, the minimum inner diameter part of the wrapping edge 17 of the paper-plastic cup cover 1 expands and deforms outwards and crosses the opening restraining edge 31, then the original body is restored immediately after the user puts the hand on the paper-plastic cup cover, and the wrapping edge 17 is pressed downwards gradually, and finally the wrapping edge 17 crosses and wraps the opening restraining edge 31 completely.
Then, when drinking the beverage in the cup body 30, as shown in fig. 9, the pushing body 22 raised on the paper-plastic cup lid 1 is pressed by hand from the front, and then the pushing body 22 is pushed backwards by applying force, the breakable tear is produced at the easy-to-tear edge 23 of the opening plate 21 connected to the drinking spout 20 at the instant of time, and the tear reaches the easy-to-turn edge 211, so that under continued application of force, the pushing body 22 and the opening plate 21 will make a backward deflection and bending action with the easy-to-turn edge 211 as the rotation axis, and as shown in fig. 9, the pushing body 22 will touch the inner surface of the stopping platform 25 first, and then push the pushing body 22 into the receiving cavity 24 to stay tightly under the action of the continued force, so that it is not shielded by the opening plate 21 and the pushing body 22, the drinking opening 20 can be completely exposed for the user to drink the beverage in the cup body 30 through the drinking opening 20.
In the structure of the paper-plastic cup lid 1 of the present invention, because the drinking hole 20 is disposed on the high platform 14 and a small space is automatically partitioned below the high platform 14, as shown in fig. 9, when a user drinks the beverage by tilting the drinking hole 20 and the cup body upward, the flow of the beverage in the cup body flows into the small space below the high platform 14, the flow is limited and buffered, so that the beverage flowing out from the drinking hole 20 becomes slow and smooth, and the user is not frightened, and the user does not worry about the splashing.
As shown in fig. 1, 2 and 8, the paper-plastic cup lid 1 of the embodiment of the present invention is designed such that the top surface 15 of the cup is not located at the center of the paper-plastic cup lid 1, but is shifted backward, such that the upper and lower "outer cups" can be easily stacked for carrying and moving, as shown in fig. 10, due to the selection of the design, the outer diameter of the bottom circle of the cup body 30 is equal to the diameter of the top surface 15 of the cup, and the distance h between the bottom surface and the bottom edge of the cup body 30 is slightly higher than the height of the baffle 25, such that when one outer cup is stacked on the top surface 15 of another outer cup from the bottom edge, the bottom edge of the upper outer cup can be just accommodated in the top surface 15 of the lower outer cup, and the space between the bottom edge and the bottom surface of the upper outer cup is just for the lower outer cup to stay by the baffle 25, thereby forming the upper outer cup as shown in fig. 10, The paper cups are overlapped.
In the embodiment of the present invention, when the upper and lower outer-band paper cups are stacked, since the upper outer-band paper cup is offset from the lower outer-band paper cup, the upper and lower outer-band paper cups are stacked left and right, so that when a user holds the upper and lower outer-band paper cups with two hands (i.e., one left hand and one right hand), the palm can be closer to the cup body 30, so that the holding stability is better, and the carrying and moving are facilitated. From the above description, the main appeal of the present invention is to apply a paper-plastic cup lid 1 made of mixed paper pulp and/or plant fiber material, and manufactured by a mold pulp-absorbing molding and hot-pressing molding technology, and is characterized in that the paper-plastic cup lid 1 has a wrapping edge 17 capable of really wrapping a binding edge 31 of a cup body 30 and a cup top surface 15 with a position offset, and the drinking hole 20 is arranged on the high platform 14, so as to achieve the effects of preventing liquid in the cup body 30 from overflowing, conveniently carrying and overlapping an outer paper cup to move, and slowing down the beverage flowing force at the drinking hole 20.
