Description

Paper-plastic cup lid

The invention relates to a paper-plastic cup lid, in particular to a paper-plastic cup that can be tightly combined with the cup body mouth, so as to avoid liquid overflow in the cup body, and is convenient to carry and move the paper cup when stacked, and can buffer the beverage flow cover.

According to press, many people, especially office workers, buy a cup of coffee from a brand chain supermarket or fast food store almost every day to start a day's work. Without drinking coffee, it seems that they can't afford the enthusiasm for work. If consumers do not bring their own accompanying cups of this kind of take-out coffee, the supermarket or fast food shop will use the "take-out paper cup" to help consumers install it, so that consumers can carry the "take-away paper cup" to carry mobile and The role of drinking at any time. "Takeaway paper cups" are also often called "disposable paper cups", "disposable cups" or "disposable paper cups" --- and so on. The paper cup with the conventional knowledge is generally composed of a cup body and a cup lid. The cup body is used to contain liquid beverage, and then the cup lid is closed at the cup mouth of the cup body, so as to avoid the overflow of the liquid beverage in the cup body.

As far as the cup lids on the paper cups commonly used in the market are commonly used, they are usually made of plastic injection molding technology such as PP, PS, PVC and other plastic materials, which are generally called "plastic cup lids". It is known that plastic cup lids cause serious pollution to the environment in terms of recycling and discarding, especially due to the large number and the difficulty of recycling, which causes serious damage to environmental protection. In the era of high environmental awareness, the use of plastic materials is once Sexual "plastic cup lids" completely deviate from environmental awareness. In addition, the conventional "plastic cup lid" is formed by plastic injection technology, which limits the moving space required for demoulding, so that the use of the "plastic cup lid" product cannot meet the demand for tightly closing the mouth of the paper cup. After being combined with the mouth of the paper cup, there is still a loss of easy leakage resulting in leakage of the beverage, which often makes the user worry about unsafe use. As for the conventional plastic cup cover, the top surface of the cup cover and the drinking port are set on the same plane due to the injection molding technology of the plastic mold, so when the user takes the mouth and drinks the drink with the mouth tilted up At this time, the liquid flow of the beverage in the cup will completely flush to the drinking port, so if the angle of the tilt of the cup is too large, the drinker will be scared by the flow of the drink, and if it is accidentally affected by the spilled drink, The lack of use caused by such unsatisfactory structure improves the real value.

At present, there have been developed paper-plastic products made by mixing pulp and/or plant fiber materials by die-suction molding and hot-press shaping technology, but most of them are manufactured as isolation buffer materials. No one ever thought of making paper-plastic cup lids from paper-plastic materials. In the present invention, paper-plastic cup lids are manufactured using paper-plastic molding technology to distinguish them from plastic cup lids and to improve the use of plastic cup lids. .

In view of the lack of use of plastic cup lids, the present inventors deeply conceived of R&D and improvement in order to create a completely new paper-plastic cup lid, which can also improve the lack of use of conventional plastic cup lids. Inventions.

The reason is that the main purpose of the present invention is to provide a paper-plastic cup lid that can be tightly combined with the cup mouth of the cup body to avoid the liquid from overflowing inside the cup body and is convenient for stacking and carrying up and down.

Another main object of the present invention is to provide a paper-plastic cup lid with a drinking port on a high platform to prevent the beverage from flowing upwards when the cup is tilted upwards.

In order to achieve the above object, the present invention specifically creates a paper-plastic cup lid with a main ring wall surrounding a circle, and the rear end side of the main ring wall forms a rear end edge upwards, and the rear end edge extends from both sides forward The extension surround turns into a horizontal side platform. The front end of the side platform is inclined to extend into a section of inclined slope protection. The front side of the two slope protection slopes are combined together to form a high platform. The inner edge of the side slope protection slope adopts a circular arc tangent type as an inner protection wall; the rear end arc edge, the side platform, the slope protection slope and the high platform surround a circle, and the middle is formed as a relatively low height and a deviated position The top surface of the rear cup is provided with a micro-vent hole; a highly concave drinking mouth is formed at the center of the high platform, and a horizontal opening plate is formed on the drinking mouth surface The inner edge is the top edge of the inner protective wall and is formed as an easy-turning edge. A high pushing body is formed at the center of the opening plate, and the connecting edge of the opening plate and the drinking port, except for the easy-turning edge The outer three sides are made into latent thin easy-to-tear edges, and the easy-to-tear edges reach the easy-turning edge; a cup hole is formed on the top surface of the cup at a distance adjacent to the high platform Behind the accommodating cavity is formed a sloping back high platform, which is surrounded by two sides to protect the accommodating cavity; the bottom of the main ring wall extends outward a small distance to become a bottom table, and then bend downward The arc extends to form a cladding edge that curves inward, and then expands outward to form a flip.

In the above-mentioned paper-plastic cup lids, the frangible edge is cut to a thickness less than half.

In order to achieve the above purpose, the present invention adopts the technical means and the practical improvement effect that can be achieved. Hereafter, the following preferred and feasible embodiments are described in detail with the drawings, and Poli fully understands it.

Please refer to FIGS. 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 die-sucking plastic molding and hot-press shaping technology, which is structured to have a surround The main ring wall 10 is formed in a circle, and the rear end side of the main ring wall 10 is turned upward to form a rear end arc edge 11. The rear end arc edge 11 extends forward and surrounds from both sides. It gradually changes into a horizontal side platform 12, the outer edge and inner edge of which are curved lines, and the curvature of the inner edge is higher than the outer edge (that is, the inner edge is more curved), and then the front end of the side platform 12 is inclined The high slope extends into a section of inclined slope protection 13, the outer edge and inner edge of the inclined slope protection 13 are also curved lines, and the curvature of the inner edge is higher than the outer edge (that is, the inner edge is more curved), the last two sides of the slope protection 13 The front heights are combined together into a high platform 14, the inner edge of the high platform 14 is connected to the inner edge of the two side slope protective slopes 13, and the inner edge of the upper wall 14 is set as an inner protective wall 141; (Figure 2) The width of the rear end is arranged from small to large. The width of the rear edge 11 is the narrowest and the first is the first, but when it extends to the two sides, it is gradually widened, and then the width of the side platform 12 is greater than The rear edge 11 is ranked second, then the width of the inclined slope protection 13 is larger than the side platform 12 and ranked third, and finally the high platform 14 is united because it extends from both sides, so the The width of the high platform 14 is the fourth largest, and the inner edges of the rear edge 11, the side platform 12, the inclined slope protection 13 and the high platform 14 (the inner edge of the high platform 14 is the tangential type) The inner protective wall 141) will be surrounded by a circle, so that the plane in the middle of the circle is formed into a cup top surface 15 with a relatively low height, and the depth of the cup top surface 15 at the rear end edge 11 is preferably 2 mm. And the cup top surface 15 is provided with a micro vent hole 151 at a distance adjacent to the rear end arc edge 11, so it can be seen that the cup top surface 15 is not located in the center of the paper-plastic cup cover 1, but presents Backward offset state, as shown in Figure 1, 2.

The upper surface of the high platform 14 is based on the outer edge of the arc, and a drinking mouth 20 with a slightly concave height is formed at the center. Please refer to FIG. 5, a horizontal opening plate is formed on the surface of the drinking mouth 20 21, the inner edge of the opening plate 21 is the top edge of the inner protective wall 141, and is formed into an arc-shaped easy-turning edge 211, and a high pushing body 22 is further formed at the center of the opening plate 21, During manufacturing, the pushing body 22, the opening plate 21 and the high platform 14 are formed into one body, and the connecting edges of the opening plate 21 and the drinking port 20, except for the easy-turning edge 211, are all three sides The latent thin easy-to-tear edge 23 is formed, that is, the connecting edges of the three sides are processed and cut to a thickness of less than one-half, and the easy-to-tear edge 23 is formed, as shown in FIG. 5 up and down The easy-to-tear edge 23 on both sides must be cut to reach the easy-turning edge 211, where it can be seen that the drinking port 20 is completely covered by the opening plate 21 and the pushing body 22 when it is not in use and does not appear, and at the same time the drinking port 20. When not in use, the easy-to-tear edge 23 exhibits a latently thin connection; on the top surface 15 of the cup, a receiving cavity 24 that is recessed downward is formed at a distance adjacent to the high platform 14. At the rear, a stopper 25 with a sloping back is formed. The stopper 25 is formed to surround the accommodating cavity 24 by two sides.

Please refer to FIG. 6, after the bottom of the main ring wall 10 extends a small distance outwards to become a bottom mesa 16, then the arc is extended downwards and formed into a cladding edge 17 of an inward curved arc, and finally Then, a circle of lift tabs 18 is expanded, and it can be seen that a micro-curved arc shape is formed from the end of the bottom table top 16 to the end of the covering edge 17, and then the end of the covering edge 17 reaches the end At the end of the slide 18, a slightly curved arc shape is formed outward

The paper-plastic cup lid 1 of the embodiment of the present invention must be used in conjunction with a cup body 30 in use. Please refer to FIGS. 7 and 8. In general, the cup body 30 will form a ring-shaped beam edge 31 at the periphery of the cup mouth. When the paper-plastic cup lid 1 of the embodiment of the present invention is to be closed on the cup mouth of the cup body 30 (of course, the cup body 30 has been filled with beverages), first, the paper-plastic cup lid 1 corresponds to the covering edge 17 Under the state of the beam edge 31, the minimum inner diameter of the covering edge 17 is slightly smaller than the outer diameter of the beam edge 31, so the covering edge 17 will be blocked by the beam edge 31 at first Can not pass, at this time, as long as the operator presses the paper-plastic cup cover 1 close to the symmetrical part and presses down with a little force, the minimum inner diameter of the covering edge 17 of the paper-plastic cup cover 1 is under force When pushed, it expands slightly and crosses the beam edge 31. In this way, the paper-plastic cup lid 1 is pressed down in a circle, and finally, as shown in FIG. 7, the covering edge 17 will completely pass and wrap Covering the beam edge 31, the paper-plastic cup lid 1 is sealed tightly on the cup body 30, and the whole "outside paper cup" (that is, the cup body 30, the internal beverage and the The paper-plastic cup lid 1) moves. If the cup body 30 is filled with hot drinks, the pressure generated can be relieved by the micro-vent holes 151 to avoid overpressure in the cup body 30.

The paper-plastic cup cover 1 of the embodiment of the present invention is made of pulp and/or plant fiber materials as a material, and is manufactured by die suction plastic molding and hot pressing shaping technology, so it is elastically deformed within a certain force range The performance can be better than the plastic cup lid, so when you press the second-hand paper-plastic cup lid 1 close to the symmetrical part, and then press down harder, the minimum inner diameter of the covering edge 17 of the paper-plastic cup lid 1 The place will expand and deform and pass the beam edge 31, and then restore the original shape immediately after letting go, so that the paper-plastic cup lid 1 is pressed under the pressure one by one, and finally the covering edge 17 is completely over and wrapped Covered the beam mouth flange 31.

Then, when you want to drink the beverage in the cup 30, as shown in FIG. 9, press the pusher 22 raised on the paper-plastic cup cover 1 from the front with your hand, and then push the pusher 22 back. At this moment, the frangible edge 23 connecting the opening plate 21 and the drinking port 20 is broken, and the tear reaches the frangible edge 211. Therefore, under the continued force, the pushing body 22 together with the The opening plate 21 will use the easy-turning edge 211 as the axis of rotation to make a deflection and bending action. At this time, as shown in FIG. 9, the pushing body 22 will first touch the inner surface of the stopper 25, and then continue Under the force, push the pushing body 22 into the accommodating hole 24 to make an urgent stop, so that since the opening plate 21 and the pushing body 22 are no longer blocked, the drinking mouth 20 can be fully exposed for The user drinks the beverage in the cup body 30 through the drinking port 20.

Take-out paper cups are often used to hold hot drinks (for example: freshly brewed hot coffee --- etc.), so the drinker must drink the drink with the mouth 20 and tilt the cup body up. In the construction of this creative paper-plastic cup lid 1, Because the drinking port 20 is set on the high platform 14, and a small space has been separated under the high platform 14, as shown in FIG. 9, when the drinker takes the mouth, the drinking port 20 is tilted and the cup is tilted up When drinking beverages from the body, when the beverage in the cup flows into the small space under the high platform 14, the flow is restrained and creates a buffer, so the beverage flowing out from the drinking port 20 becomes slow and smooth, so as not to scare the drinker , Not to mention spills.

As shown in FIGS. 1, 2, and 8, the paper-plastic cup cover 1 of the embodiment of the present invention is created so that the cup top surface 15 is not located in the center of the paper-plastic cup cover 1, but is in a state of being shifted backward, so In order to allow the two upper and lower "outside paper cups" to be easily stacked to facilitate carrying and movement, please refer to Figure 10, due to the design choice in advance, the outer diameter of the bottom circle of the cup body 30 is equivalent to this 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 stopper 25, so one outer paper cup is stacked from the bottom edge of the other outer paper cup When the top surface 15 of the cup, the bottom edge of the outer paper cup can be accommodated in the top surface 15 of the bottom outer paper cup, and the space between the bottom edge of the outer paper cup and the bottom surface is just for the stop 25 of the outer paper cup It stays, so that the upper and lower outer paper cups are stacked as shown in FIG. 10.

In the embodiment of the present invention, when the upper and lower outer paper cups are stacked, because the upper outer paper cups are shifted in position relative to the lower outer paper cups, the upper and lower outer paper cups will show one left and one right In the stacked state, when the user supports the upper and lower two paper cups with the second hand (ie, one left hand and one right hand), the palm can be closer to the cup body 30 so that the stability of the support is better, which is convenient for carrying and moving.

As can be seen from the above description, the main claim of the present invention is to apply for a paper-plastic cup lid 1 made by mixing pulp and/or plant fiber materials into materials, which is manufactured by die-suction molding and hot-press shaping technology. The paper-plastic cup lid 1 as claimed has a covering edge 17 that can surely cover the rim 31 of the cup body 30 and a cup top surface 15 with a position offset, and the drinking port 20 is provided on the high platform 14 In order to achieve the effect of avoiding the overflow of the liquid in the cup body 30 and being convenient to carry and move the paper cup outside the stack, and to slow down the beverage flow at the drinking port 20.

To sum up, the present invention does have absolute novelty and practical advancement. I have applied for a patent for the invention in accordance with the law. I urge you to grant the patent for this case as soon as possible after examination.
