Molded Pulp Cup Lid

FIELD OF THE INVENTION The present invention relates to a molded pulp cup lid, and in particular, closely coupled with the inlet of the cup body to prevent the liquid in the cup body from overflowing, and to facilitate the carrying out of the paper cup that is superimposed and taken out for convenient portability It relates to a molded pulp cup lid that slows down the flow rate.

As you know, many people, especially office workers, buy a cup of coffee almost every day at a brand chain, a super market or a fast-food restaurant and start their day, and almost everyone can't be passionate about it unless they drink it. do. If the takeout coffee is not carried by the consumer, the supermarket or fast food store may help the consumer and pack it as a takeout paper cup so that the consumer can carry and carry the takeout paper cup in his hand. Make sure Takeout paper cups are also often referred to as molded pulp cups, disposable convenience cups or discarded paper cups. Takeout paper cups, which are now widely known, typically consist of one cup body and one lid, the cup body containing liquid beverage, and then the cup lid closing the cup body inlet to close the liquid beverage in the cup body. To prevent the overflow.

Lids that are incorporated into commercially available takeout cups are typically manufactured by plastic injection molding techniques using plastic materials such as PP, PS, and PVC, and are commonly referred to as "plastic cup lids". Known plastic cup lids cause serious pollution to the environment, both in terms of recovery and disposal, especially due to the large quantity of water, which is not easy to recover, causing serious injury to the environment. Nowadays, the awareness of environmental protection is strengthened, and the manufacture of disposable plastic cup lids using plastic materials has virtually violated environmental awareness. In addition, since the known plastic cup lid is molded by a plastic injection technique, the space required for removing the mold from the mold is limited, and thus the demand for covering the paper cup inlet when using the finished product of the plastic cup lid is not satisfied. Therefore, there is a closed end that is still easily loosened and leaks after being combined with the paper cup inlet, so that the user can always use the known 'plastic cup lid' by the plastic mold injection technique, so that both the top of the cup lid and the drinkware are the same It is located on a flat surface, and when the user drinks the drink by tilting the cup body up against the drink, the liquid in the cup body moves to the drinking device. The splashed beverage will be damaged. Due to such a structural closure, a shortcoming in terms of use appears, and therefore, practical improvement is necessary.

Currently, molded pulp products are manufactured by mixing pulp and / or plant fiber materials as materials, sucking pulp into molds, injection molding, and hot roll forming technology, but mostly using isolation buffer materials. There are many. Nobody has ever devised a technical solution for producing a molded pulp cup lid from a molded pulp material. The present invention discloses a technical solution to improve the problem of using a plastic cup lid by producing a molded pulp cup lid by the molded pulp molding technology with a molded pulp and distinguished from the plastic cup lid.

Both the outer edge and the inner edge of the base 13 are arcuate lines, the curvature of the inner edge is greater than the outer edge (i.e., the inner edge is relatively bent), and finally, the high of the front end of both inclined guards 13 The places are joined together into a single high platform 14, where the inside edge of the high platform 14 and the inside edges of both inclined guards 13 are connected longitudinally with one inner protective wall using an arcuate tangential. Install 141;

The respective portions are arranged from a small size to a large size when viewed from the bottom (shown in FIG. 2), the narrowest width of the trailing arcuate edge 11 being arranged first as the first one, which is extended to both sides. Only gradually widen, and then the width of the side platform 12 is arranged in a second larger than the trailing arcuate edge 11, and then the width of the inclined guard 13 is greater than the side platform 12. Kerr is arranged in a third, and finally, the high platform 14 extends from both sides and is integrally connected so that the width of the high platform 14 is arranged to be the fourth largest, and at the same time, the trailing arcuate edge 11 ), The inner edge of the side platform 12, the inclined guard 13 and the four high platform 14 (the inner edge of the high platform 14 is the tangential inner protective wall 141) Wrapped in the form of a circle so that the plane located in the middle of the circle is formed as the cup top face 15 having a relatively low height, and the depth of the cup top face 15 and the rear arcuate edge 11 portion. Is 2 mm, and the cup top surface 15 constitutes one built-in hole 151 recessed down at a distance adjacent to the trailing arcuate edge 11. As can be seen from this, as shown in FIGS. 1 and 2, the cup top surface 15 is not located in the center of the molded pulp cup lid 1, but implements a state that is deflected backwards. .

The upper surface of the high platform 14 forms a drinking utensil 20 having one height slightly recessed downward in a central portion with respect to the outer edge of the arch, and as shown in FIG. 5, the drinking utensil ( 20) one horizontal opening plate 21 is formed on the surface, and the inner edge of the opening plate 21 is the top edge of the inner protection wall 141, and the portion is one arcuate easily folded edge 211. And a further protruding propellant 22 in the central portion of the opening plate 21, and the propellant 22, the opening plate 21 and the high platform when formed through a manufacturing process. 14 is formed in one piece, and the connecting edges of the opening plate 21 and the drinking appliance 20 are composed of three easy-to-pick edges 23 except for the easy-to-fold edge 211. Ie the three edges The connecting edges are all cut into thinner than one-half of the thickness and constitute the easy picking edge 23. As shown in FIG. 5, the easy picking edge 23 of the two upper and lower edges is the easy folding edge. It should be cut to reach 211. As can be seen from this, when the drinking utensil 20 is not used, it is not completely covered by the opening plate 21 and the propellant 22 when not in use, and when the drinking utensil 20 is not used. The easy-to-pick edge 23 implements a thin connection relationship; The cup top surface 15 constitutes one built-in hole 24 recessed down in one place located at a distance adjacent to the high platform 14 and the back of the built-in hole 24 is inclined at the rear side. One step 25 is formed to protrude in a state, and the step 25 is formed to surround the both sides to protect the built-in hole 24.

As shown in FIG. 6, the bottom of the main annular wall 10 is shortly connected to the outside to form one pedestal face 16, and then extends while arching in an arcuate downward direction toward the inward direction. One covering edge 17 is formed arcuately curved, and finally extends outward to form one folding sheet 18. As can be seen from this, at the site extending from the end of the pedestal face 16 to the end of the covering edge 17, a slightly inwardly curved arcuate is formed, and then from the end of the covering edge 17 the One outwardly curved arcuate is formed in the area leading up to the folding sheet 18.

Molded pulp cup lid 1 according to an embodiment of the present invention must be used to form a custom with one cup body 30 when using, as shown in Figure 7, 8, the general cup body 30 ) Forms one annular mouthpiece edge 31 around the cup inlet, when the molded pulp cup lid 1 according to the embodiment of the invention tries to close the cup inlet of the cup body 1. (Of course, the cup body 30 already contains a beverage), first, the molded pulp cup lid 1 is covered with the cover edge 17 in a state corresponding to the mouthpiece edge 31, but the Since the minimum inner diameter of the covering edge 17 is slightly smaller than the outer diameter of the mouthpiece edge 31, the covering edge 17 is initially restrained by the mouthpiece edge 31 and cannot pass through, whereby the operator has two hands. With the molded pulp cup lid 1 approaching Hold the symmetrical part and press it down with a slight force to push down the minimum inner diameter part of the coated edge 17 of the molded pulp cup lid 1 to be slightly pushed out to extend the segument edge 31. As described above, as described above, the molded pulp cup lid 1 is pushed round and round, and finally, as shown in FIG. 7, the covering edge 17 pushes the mouthpiece edge 31. By covering over completely, the molded pulp cup lid 1 covers the cup body 30 tightly and tightly. At this time, the integrated 'take-out paper cup' (ie, the cup body 30, the inner beverage and the molded pulp cup lid) can be carried and moved, and is produced by the hot beverage contained in the cup body 30. The pressure is reduced through the fine vent hole 151 to avoid the occurrence of super-pressure in the cup body 30.

Molded pulp cup lid 1 according to an embodiment of the present invention is used as a material by mixing the pulp and / or plant fiber material, suction molding the pulp with a mold, injection molding, manufactured by hot rolling shaping technology to constant pressure range Since the elastic deformation performance in the inside is superior to that of the plastic cup lid, the molded pulp cup lid is pressed with a slight force to hold the molded pulp cup lid 1 near and symmetrically with two hands, The minimum inner diameter portion of the covering edge 17 of (1) extends outward and deforms beyond the mouthpiece edge 31, and then immediately releases the hand to return to its original shape. As described above, if the molded pulp cup lid 1 is pressed upwards upwards, the covering edge 17 finally covers the mouthpiece protruding edge 31.

Then, when you want to drink the beverage in the cup body 30, as shown in Fig. 9, by pressing the propellant 22 protruding from the molded pulp cup lid 1 from the front by hand, press again When the propellant 22 is pushed backward, the picking edge 23 that momentarily connects the opening plate 21 and the drinking appliance 20 bursts to reach the easy folding edge 211. Will be counted until. Accordingly, if the pressure is continuously applied, the propellant 22 moves with the opening plate 21 to be deflected in the rearward direction with the rotatable edge 211 as the center of rotation. In this case, as shown in FIG. 9, the propellant 22 first contacts the inner surface of the step 25 and then moves the propellant 22 into the built-in hole 24 under continuous pressurization. Immediately stop. As described above, since the fraud opening plate 21 and the propellant 22 are not restrained, the drinking utensil 20 is completely exposed so that the user can enter the cup main body 30 through the drinking utensil 20. Have a drink.

Takeout paper cups always take hot drinks (for example, hot coffee, etc.), so that the drinker must touch the drinking apparatus 20 by mouth and tilt the cup body upward to drink the drink. The molded pulp cup lid 1 according to the present invention has a drinking appliance 20 installed on the high platform 14 in terms of construction, and isolates one small space by itself from the high platform 14 side. As shown in FIG. 9, when the drinker drinks the beverage by touching the drinking appliance 20 with the mouth and tilting the cup body upward, when the drink water in the cup body flows into the small space of the high platform 14, the moving speed is increased. Constrained to be late Therefore, the drinking water flowing out from the drinking apparatus 20 becomes slower and calmer, so that the drinker does not need to be surprised and does not have to worry about the splashing damage situation.

As shown in Figs. 1, 2 and 8, the molded pulp cup lid 1 according to the embodiment of the present invention has the cup top surface 15 without the center of the molded pulp cup lid 1. Since it is implemented to be deflected backwards, it is convenient to carry the two 'take-out paper cups' at the top and the bottom to facilitate the operation. As shown in FIG. 10, by prior design selection, the outer diameter of the bottom circular shape of the cup main body 30 is equal to the diameter of the cup top surface 15, and also the bottom surface of the cup main body 30. Since the distance h between the bottom edges is slightly higher than the height of the step 25, the bottom of the upper takeout paper cup when one takeout paper cup overlaps with the cup top face 15 of the other takeout paper cup whose bottom edge is different. Since the edge is embedded inside the cup top surface 15 of the lower take-out paper cup, the space between the bottom edge and the lower surface of the upper take-out paper cup allows the step 25 of the lower take-out paper cup to enter and stay. As shown at 10, the top and bottom take-up paper cups form a superimposed shape.

In the embodiment of the present invention, when the upper and lower takeout paper cups are stacked, the upper takeout paper cups are relatively biased relative to the lower takeout paper cups. One left and one left constitute a superimposed state. As described above, if the user supports the two takeout paper cups up and down with both hands (ie one right hand and one left hand), the palms will be closer to the cup body 30, resulting in more stability of the support. It is excellent, and it is convenient to carry.

As can be seen from the above description, the present invention mainly uses molded pulp and / or plant fiber materials as a material, suctioned pulp with a mold for injection molding, and a molded pulp cup lid manufactured by hot rolling shaping technology. 1), wherein the molded pulp cup lid 1 has a covering edge 17 which can cover the cup body 30 mouthpiece edge 31 securely, and one position deflected cup The top surface 15 is installed, and the drinking appliance 20 is installed on the high platform 14 to prevent the liquid in the cup main body 30 from flowing out, and to move the paper cup wool that is taken over and taken out for convenience of carrying. It is convenient to, characterized in that the effect of reducing the flow rate of the beverage of the drinking apparatus (20).

Overall, the present invention has absolute novelty and practical creativity, so the invention patent is filed in accordance with the relevant law, so please review and delegate the patent right to this application as soon as possible.
