Definitions

  • the invention relates to a recloseable lid for use with a drinking cup.
  • the invention relates to a recloseable lid assembly operable between an open position where a user can consume the contents of the cup and a closed position where the contents ofthe cup are inhibited from splashing.
  • the recloseable lid assembly has characteristics suitable for disposable use, especially in the fast-food or take-out food market.
  • Disposable cups with lids that can be installed to inhibit splashing while allowing consumption of the liquid contained therein are well-known in the industry.
  • One type of lid incorporates a series of narrowly spaced, baffled slots through which the liquid can be consumed. The narrow spacing of the slots and the baffles minimize but do not eliminate splashing while allowing the liquid to be consumed.
  • Another type of lid incorporates a flap that can be torn back from the rim of the cup toward the center of the lid and secured in an open position to provide a drinking aperture. The flap can be reattached to the rim of the cup, but it will not prevent spilling of the contents.
  • Non-disposable, recloseable lids that can be used with non- disposable cups that can sufficiently inhibit splashing during the normal operation of the motor vehicle.
  • One such recloseable lid comprises a well that is sized to be received within the opening of the cup. Multiple O-rings are disposed about a peripheral wall of the well and contact the cup to form a liquid-seal therebetween.
  • a bottom wall of the well has a through opening permitting the passage of liquids from the cup.
  • a rotatable cover is positioned within the well against the bottom wall and includes a projection and a through opening. When the through openings of the well and the cover align, a consumer can drink the contents from the cup. When the projection is received within the well through opening, the cup is closed.
  • the recloseable well structure is advantageous in that the lid can be closed to inhibit splashing and to the extent liquid is splashed, it can be retained in the well.
  • the lid is disadvantageous in that the well structure extends into the cup, which reduces the cup liquid capacity.
  • the lid is also not suitable for use as a disposable lid in the fast-food or take-out food market because of its apparent manufacturing complexity.
  • the prior lids are also not suitable for disposable use in the fast-food or takeout food markets because they are made by injection molding. The nature of the injection molding process makes these lids unsuitable for disposable use because of the relatively high cost and low production rates. Disposable lids are typically fabricated from thermoforming or vacuum forming due to lower fabrication costs and higher production rates.
  • Injection molded lids generally use a much greater amount of material and have a greater thickness than thermoformed lids.
  • the additional material and thickness is well suited for non-disposable lids, but adds additional and unnecessary cost for a disposable lid where only a one-time use is anticipated.
  • the injection molding process is more suitable for making lids with complex shapes and strong connection/support structures, without a lot of material waste.
  • the injection mold defines a three-dimensional cavity that is filled with molten plastic to form the lid.
  • the mold can be made to accommodate almost any desired three- dimensional shape.
  • the thermoforming process uses an effectively two- dimensional sheet of material that is pressed around a form.
  • a recloseable lid having an integral closure device extending from the lid upper surface can be easily formed by injection molding.
  • such a lid cannot be formed with the thermoforming process, unless the integral closure is formed by tearing-away a portion of the lid upper surface, because both the lid and closure device must be made from the same portion of the sheet.
  • thermoforming can be thought of as the injection molding process can form pieces having varying thickness whereas the thermoforming process can only make parts having a thickness equal to, or due to stretching, less than, the thickness of the sheet material. Therefore, while the injection molding process can have increased thickness portions, such as webs, gussets, and the like, no such increased thickness portion can be made with the thermoforming process.
  • the ability of the injection mold to be crafted to handle complex designs is disadvantageous when it comes to production rates. The mold must be closed, filled with molten plastic, which then must be cooled sufficiently to retain its shaped prior to the opening of the mold.
  • thermoforming process uses a web of plastic that is heated to or beyond its glass state, which permits the web to be shaped but does not require a long cooling time as the injection mold system.
  • thermoformed web is shaped and advanced to the next production step much faster than with the injection mold. The end result being the thermoforming process has much higher production rates.
  • the invention relates a recloseable lid for a drinking cup comprising a base and a cap in mating relationship which can rotate relative to each other. Both the base and cap are provided with an aperture for delivery of liquid therethrough. When the apertures are aligned, liquid may be removed from the cup. When the cap is rotated relative to the base so that the apertures are offset, removal and spillage of liquid will be prevented.
  • the lid comprises a mounting ring defining a peripheral channel sized to receive the rim of a cup for mounting the lid to a cup.
  • a base is provided and is connected to and extends from the mouting ring.
  • the base has a drink opening and defines a well with an annular groove.
  • a cap is provided and has a plug for closing the drink opening and an annular edge sized to be inserted into the well and received within the annular groove to rotatably mount the cap to the base.
  • the cap can be rotated relative to the base between and opened position, where the plug does not close the drink opening, and an closed position where the plug closes the drink opening.
  • the lid comprises a mounting ring defining a peripheral channel sized to receive the rim of a cup for mounting the lid to a cup.
  • a base connects to and extends from the mouting ring.
  • the base has a drink opening for the passage of liquid from the cup through the lid when the lid is attached to the cup.
  • a cap rotatably mounted to the base, is rotated to operate the lid between and opened and a closed postion.
  • the cap has a pass-through opening that aligns with the drink opening when the lid is in the opened position and a plug that aligns with the drink opening for closing the drink opening when the lid is in the closed position, the cap, mounting ring, and tab are formed from a plastic sheet and have a substantially uniform thickness.

It should be noted that it is not necessary for the lid assembly 10 to be initially set in the closed position. However, it is highly preferred that the lid assembly 10 be initially set in the closed position since it will better insure that when the lid assembly 10 is placed on the cup 12 the lid assembly 10 will be closed and thereby reduce the possibility of spillage.

It is contemplated that the user will use at least one of the closely spaced grips and the other grip so that the user's fingers are in a generally opposing relationship.
  • the resulting orientation ofthe cap 18 and the base 16 upon their relative movement is more complex than is immediately seen and aids in enhancing the seal between the detents and aperture detents along with improving the tactile feel of the lid assembly 10 which is primarily, but not solely, attributable to the very slight elliptical shape of the receptacles 38, 66 along with their inclined inner walls 40, 68.

  • the frictional resistance, if any, between the inner walls 40, 68 is minimized.
  • the major axis C of the cap receptacle 66 will rotate relative to the major axis B of the base receptacle 38, resulting in the vertices of the cap receptacle 66 moving towards the minor axis of the base receptacle 38.
  • the contact pressure between the ends of the cap receptacle 66 and the base inner wall 40 will increase as the cap 18 is rotated relative to the base 16 from the midway point to either the open or closed position since the end of the cap is continuously pressed against the base inner wall 40 whose radius of curvature decreases from the major to the minor axis.
  • the depth of the receptacle 38 is preferably, but not necessary, greater than the depth of the receptacle 66 to permit the cap 18 to be drawn toward the base 16 a sufficient amount just prior to or in the absence of contact between the receptacle floors 39, 67.
  • FIGS. 13 and 15 show the conversion of the rotational movement to the translational movement.
  • FIG. 13 shows the relationship between the cap and base in the midway position where there is a gap between the bottom walls 39, 67.
  • FIG. 15 shows the cap and the base in the closed position where the gap has substantially disappeared because of the translational movement resulting from the rotation of the cap.
  • the translational movement of the cap 18 relative to the base 16 can be thought of as the cap 18 applying a compressive force to the base 16.
