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.
Most people, particularly office workers, would buy a cup of coffee from a branded chained convenience store or a fast food restaurant to start a day's work almost every day. Without drinking coffee, one seems to be lacking in enthusiasm for work. If consumers do not bring their own cups for the takeout coffee, then convenience stores or fast food stands will use a “takeout paper cup” to help the consumers to contain the coffee and let the consumers carry the “takeout paper cup” and drink the coffee from the paper cup. Such “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.
In general, 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. In addition, 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. After the paper cup is combined with the cup rim, they may be loosened easily and cause a leakage of the beverage, and users has the safety concern of the use. Further, 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. Obviously, the aforementioned structure of the conventional paper cup requires improvements.
At present, a mixture of paper pulp and/or plant fiber has been developed, and the mixture is processed by molding, grouting, and shaping as well as hot press molding to form a pulp molded product, but most of the products are made of isolation buffer materials, and no one ever thought that it would be molded into the molded pulp cup lid by using the pulp molded material. Unlike the conventional plastic cup lid, 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.
In view of the drawbacks of the conventional plastic cup lid, the inventor of the present invention based on years of experience in the related industry to conduct extensive research and experiment, and finally developed molded pulp cup lid to overcome the drawbacks of the conventional plastic cup lid.
Therefore, it is 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.
To achieve the above-mentioned objective, 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 opening being concavely formed in the height-wise direction at the center position of the high platform, and a horizontal opening plate being formed on a side of the drinking opening, and the inner edge of the drinking opening being the top edge of the inner protective wall to constitute an easy folding edge, and a pusher being formed and protruded from the central position of the opening plate, and the connecting edges of the opening plate and the drinking opening except the easy folding edge being tapered thin easy-to-tear edges, and the easy-to-tear edges reaching the easy folding edge; and an accommodating cavity being downwardly and concavely formed on the cup top and at a position with a distance from the high platform, and a hatchback raised blocking platform being formed at the rear of the accommodating cavity, and the blocking platform encircling the accommodating cavity from both sides; and the bottom of the main surrounding wall extending outwardly to a small distance to form a countertop and then bent downwardly and extended to inwardly in an arc shape to form a covering edge, and then expanded outwardly to form a lift plate.
According to the above-mentioned molded pulp cup lid, the easy-to-tear edge is cut into a thickness smaller than half of its original thickness.
The present invention will become clearer in light of the following detailed description of an illustrative embodiment of this invention described in connection with the drawings.
With reference to
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. In
With reference to
During the use of the molded pulp cup lid 1 in accordance with an embodiment of the present invention, the molded pulp cup lid 1 is used with a cup 30. In
In an embodiment of the present invention, 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. When the user press the molded pulp cup lid 1 into a symmetrical part by hands and applies a slight force to press the molded pulp cup lid 1 downward, 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. By pressing different positions of the molded pulp cup lid 1, the covering edge 17 can cross and cover the binding edge 31.
In
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. In the structure of the molded pulp cup lid 1 of the present invention, 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
With reference to
In an embodiment of the present invention, 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. When 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.
