Definitions

  • the present invention relates to a molded pulp cup lid, and more particularly to the molded pulp cup lid capable of combining with a cup rim tightly to prevent the liquid contained in a cup from spilling out and facilitate user to carry, stack, or move takeout paper cups, and retard the flow of beverage.
  • takeout paper cup is often called “single-use paper cup”, “single-use portable paper cup” or “disposable paper cup”.
  • the conventional takeout paper cup is usually composed of a cup and a cup lid, and the cup is provided for containing liquid beverage, and the cup lid is covered onto the cup rim to prevent the liquid beverage contained in the cup from spilling out.
  • the conventional cup lid used for the takeout paper cup is made of a plastic material such as PP, PS, PVC, etc. and manufactured by plastic injection molding, and such product is usually called a “plastic cup lid”.
  • the conventional plastic cup lid has recycle and disposal issues which produce serious pollutions. Particularly, the quantity is huge, and thus it is very difficult for the recycle process and leads to serious damages to the environment. With today's high awareness of environmental protection, the use of a disposal plastic cup lid is totally contrary to the awareness of environmental protection.
  • the conventional plastic cup lid is manufactured by the plastic injection molding and thus limited by the moving space required for the demolding, so that the plastic cup lid product cannot satisfy the requirement of covering the paper cup onto the cup rim tightly.
  • the conventional plastic cup lid is formed by the plastic injection molding, so that the top of the cup lid and the drinking opening are arranged on the same plane, and when a user sets his/her mouths close to the drinking opening and tilts the cup for drinking the beverage, the whole of the liquid of the beverage contained in the cup rushes to the drinking opening, so that if the user tilts the cup with a too-large angle, the flow of the beverage will be too fast and may even spill out from the cup.
  • the aforementioned structure of the conventional paper cup requires improvements.
  • the present invention adopts the molded pulp cup lid manufactured by the pulp molding process to overcome the drawbacks of the conventional plastic cup lid.
  • a primary objective of the present invention to provide a molded pulp cup lid capable of combining with a cup rim tightly to prevent liquid or beverage contained in a cup from spilling out, and allowing users to stacks several cups with one another to facilitate the carry of the cups.
  • Another objective of the present invention is to provide a molded pulp cup lid having a drinking opening formed on a high platform to prevent the beverage contained in the cup from having a too large flow when the cup is tilted for drinking.
  • the present invention is particularly to provide a molded pulp cup lid, comprising a main surrounding wall surrounded into a circle, a rear arc edge upwardly erected from a rear side of the main surrounding wall, and both sides of the rear arc edge extending forward and surrounding from both sides to form a horizontal side platform, and the front of the side platform being inclined and extended to a section of an oblique protective slope, and the fronts of the oblique protective slopes on both sides being combined into a high platform, and the junction of an inner edge of the high platform and the inner edges of the oblique protective slopes on both sides being tangentially drooped in an arc shape to form an inner protective wall; and the rear arc edge, side platform, oblique protective slope and high platform being surrounded into a circle, and a cup top being formed at the middle and having a height lower than the cup top after being offset, and the cup top having a small venting hole formed thereon; and a drinking
  • the easy-to-tear edge is cut into a thickness smaller than half of its original thickness.

  • FIG. 6 is a blowup view of Section b of FIG. 4 ;
  • FIG. 7 is a blowup view of a covering edge covering a cup binding edge in accordance with an embodiment of the present invention.
  • FIG. 8 is a perspective view of a molded pulp cup lid covering a cup in accordance with an embodiment of the present invention.
  • FIG. 9 is a schematic view of a molded pulp cup lid pushing a pusher to turn in accordance with an embodiment of the present invention.
  • FIG. 10 is a schematic view of covering a molded pulp cup lid onto a cup and stacking them together vertically in accordance with an embodiment of the present invention.
  • the molded pulp cup lid 1 is manufactured by molding, suction, shaping, and hot press molding, and the molded pulp cup lid 1 comprises a main surrounding wall 10 surrounded into a circle, and a rear arc edge 11 upwardly erected from a rear side of the main surrounding wall 10 , and the rear arc edge 11 extends forwardly and surrounds from both sides for approximately half of a circle to gradually form a horizontal side platform 12 , and an outer edge and an inner edge of the rear arc edge 11 are curved lines, and the inner edge has a curvature greater than that of the outer edge (or the inner edge is more curved than the outer edge), and then the front of the side platform 12 is inclined upwardly and extended to a section of an oblique protective slope 13 , and both of the outer edge and inner edge of the oblique protective slope 13 are curved lines, and the inner edge has a curvature greater than that of the outer edge (
  • the widths arranged in an ascending order are the width of the rear arc edge 11 (but it is wider when extending sideway), the width of the side platform 12 (which is greater than the width of the rear arc edge 11 ), the width of the oblique protective slope 13 9 (which is greater than the width of the side platform 12 ), and finally the width of the high platform 14 (since it is formed by extending both sides into one), so that the high platform 14 has the fourth largest width, and the inner edges of the rear arc edge 11 , the side platform 12 , the oblique protective slope 13 and the high platform 14 (wherein the inner edge of the high platform 14 is the tangential inner protective wall 141 ) are surrounded into a circle, and the plane situated on the plane of the middle of the circle has a height below the cup top 15 , and the depth of the cup top 15 at the rear arc edge 11 is preferably 2 mm, and a small venting hole 151 is formed on the cup top 15 and at a position with a distance from the rear arc edge
  • the upper side of the high platform 14 is based on the arc outer edge, and a drinking opening 20 with a slight downward recession in the height-wise direction is formed at the central positon.
  • a horizontal opening plate 21 is formed on a side of the drinking opening 20
  • the inner edge of the opening plate 21 is the top edge of the inner protective wall 141 at where an arc easy folding edge 211 is formed
  • a raised pusher 22 is formed at the central position of the opening plate 21 .
  • the pusher 22 , the opening plate 21 and the high platform 14 are integrally formed as a whole, and the connecting edges of the opening plate 21 and the drinking opening 20 excluding the easy folding edge 211 are tapered thin easy-to-tear edge 23 .
  • the aforementioned three connecting edges are cut to a thickness less than half of its original thickness to form the easy-to-tear edges 23 , and the top and bottom easy-to-tear edges 23 as shown in FIG. 5 must be cut to reach the easy folding edge 211 . Therefore, when the drinking opening 20 is not in use, the drinking opening 20 is not exposed, but completely covered by the opening plate 21 and the pusher 22 . In the meantime, when the drinking opening 20 is not in use, the easy-to-tear edges 23 are connected in a tapered thin manner.
  • the cup top 15 has an accommodating cavity 24 downwardly and concavely formed thereon and at a position with a distance from the high platform 14 , and a hatchback raised blocking platform 25 formed at the rear of the accommodating cavity 24 , and the blocking platform 25 encircles the accommodating cavity 24 from both sides.
  • the main surrounding wall 10 are bent downwardly and extended to form an arc covering edge 17 , and finally expanded into a ring-shaped lift plate 18 .
  • An inwardly and slightly curved shape is defined from an end of the countertop 16 to an end of the covering edge 17
  • an outwardly and slightly curved shape is defined from an end of the covering edge 17 to an end of the lift plate 18 .
  • the molded pulp cup lid 1 is used with a cup 30 .
  • a ring-shaped binding edge 31 is generally formed at a cup rim of a cup 30 , so that when the molded pulp cup lid 1 is covered onto the cup rim of the cup 30 (filled with a beverage), the molded pulp cup lid 1 is covered onto the binding edge 31 in correspondence with the covering edge 17 . Since the covering edge 17 has a minimum inner diameter slightly smaller than the outer diameter of the binding edge 31 , therefore the covering edge 17 will be blocked by the binding edge 31 and cannot be passed through at the beginning.
  • the whole “takeout paper cup” (including the cup 30 , the beverage contained in the cup, and the molded pulp cup lid 1 ) can be moved safely. If a hot drink is filled into the cup 30 , the pressure produced in the cup 30 can be released from the small venting hole 151 to prevent overpressure in the cup 30 .
  • the molded pulp cup lid 1 is made of a mixture of paper pulp and/or plant fiber, and manufactured by molding, pulp suction, shaping, and hot press molding, so that the plastic cup lid preferably has a good deformation performance and elasticity within a force applying range.
  • the covering edge 17 at the position of the minimum inner diameter of the molded pulp cup lid 1 will be expanded outwardly to cross the binding edge 31 , and the covering edge 17 will restore its original shape after the user releases his/her hands.
  • the covering edge 17 can cross and cover the binding edge 31 .
  • the takeout paper cup generally contains hot drink (such as freshly brewed coffee, etc.), so that the user must set his/her mouth onto the drinking opening 20 and tilts the cup in order to drink the beverage.
  • the drinking opening 20 is formed on the high platform 14 , and the bottom of the high platform 14 is separated to provide a small space as shown in FIG. 9 , so that when the user sets his/her mouth to the drinking opening 20 and tilts the cup to drink the beverage, the beverage contained in the cup will flow into the small space under the high platform 14 , and the flow is limited to produce a buffering effect.
  • the beverage can flow slowly and smoothly out from the drinking opening 20 without the risk of scaring the user or spilling the beverage on the user.
  • the cup top 15 is not situated at the center of the molded pulp cup lid 1 but situated in an offset status, so that two “takeout paper cups” can be stacked with each other to facilitate their carry.
  • this invention designs the bottom of the cup 30 has an outer diameter equal to the diameter of the cup top 15 , and the distance h between the bottom surface and the bottom edge of the cup 30 is slightly greater than the height of the blocking platform 25 , so that the bottom of a takeout paper cup can be put on the cup top 15 of another takeout paper cup, and the bottom of the upper takeout paper cup can be placed exactly into the cup top 15 of the lower takeout paper cup, and the space between the bottom edge and bottom surface of the upper takeout paper cup can be provided for allowing the blocking platform 25 of the takeout paper cup to stay. Therefore, the upper and lower takeout paper cups can be stacked with each other as shown in FIG. 10 .
  • the upper takeout paper cup when the upper and lower takeout paper cups are stacked, the upper takeout paper cup is offset with respect to the lower takeout paper cup, so that the upper and lower takeout paper cups will be stacked in a way that one on the left and the other one on the right.
  • the user hold the upper and lower takeout paper cups by both hands including a left hand and a right hand
  • the user's palm can touch the cup 30 closer to provide a better stability to facilitate the carry of the cup 30 .
  • the main idea of the present invention is to use a mixture of paper pulp and/or plant fiber to produce molded pulp cup lid 1 by the manufacturing processes including molding, pulp suction, shaping, and hot press molding.
  • This invention is characterized in that the molded pulp cup lid 1 comprises the covering edge 17 capable of covering the binding edge 31 of the cup 30 , the cup top 15 with an offset position, and the drinking opening 20 formed on the high platform 14 and has the effects of preventing the beverage (or liquid) contained in the cup 30 from spilling out, facilitating the carry of the cups 30 by stacking them on top of one another, and retarding the flow of the beverage flowing out from the drinking opening 20 .
