LID FOR A CUP
The lid for a cup has a flange, an outer retainer, an inner retainer, a mounting groove and a protrusion. The cap covers on a cup and has a rim. The flange protrudes from the rim of the cap and has an outer edge and an inner edge. The outer retainer protrudes perpendicularly from the outer edge of the flange and has an inside surface. The inner retainer protrudes perpendicularly from the flange near the inner edge of the flange and is slanted toward the outer retainer. The mounting groove is formed in the flange and defined between the outer retainer and the inner retainer. The protrusion is formed on and protruding from the inside surface of the outer retainer and extends into the mounting groove.
1. Field of the Invention
The present invention relates to a lid, and more particularly to a lid having an inner retainer and an outer retainer respectively clamping a top edge of a cup from inner and outer sides to hold the lid on the cup tightly.
2. Description of Related Art
With reference
However, the cup 92 may be made of paper generally and is not strong enough to resist a pressing force. When the user takes the cup 92 with the lid 90, a holding force presses the cup 92 and changes the shape of the cup 92 easily. Therefore, a part of the abutting ring 95 of the lid 90 leaves from the top edge of the cup 92 and shapes intervals between the abutting ring 95 and the top edge of the cup 92. The liquid contained in the cup 92 is easily sprinkled out from the intervals. Furthermore, the lid 90 loses a covering effect and might fall off from the cup 92.
To overcome the shortcomings, the present invention intends to provide a lid to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTIONThe main objective of the present invention is to provide a lid with an inner retainer and an outer retainer respectively clamping a top edge of a cup from inner and outer sides and keeping the lid mounted on the cup tightly.
The lid has a cap, a flange, an outer retainer, an inner retainer, a mounting groove and a protrusion. The cap covers on a cup and has a rim. The flange protrudes from the rim of the cap and has an outer edge and an inner edge. The outer retainer protrudes perpendicularly from the outer edge of the flange and has an inside surface. The inner retainer protrudes perpendicularly from the flange near the inner edge of the flange and is slanted toward the outer retainer. The mounting groove is formed in the flange and defined between the outer retainer and the inner retainer. The protrusion is formed on and protruding from the inside surface of the outer retainer and extends into the mounting groove.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in junction with the accompanying drawings.

The flange is annular in shape and protrudes from the rim of the cap 10 and has an outer edge and an inner edge. The outer retainer 11 shapes annular and protrudes substantially perpendicularly from the outer edge of the flange opposite to the cap 10 and has an inside surface. The inner retainer 12 shapes annular and protrudes from the flange opposite to the cap 10 near the inner edge of the flange. The inner retainer 12 is slanted toward the outer retainer 11. With reference to
The mounting groove 13 is formed in the flange and defined between the outer retainer 11 and the inner retainer 12 and has a diameter. The protrusion 14 is formed on and protrudes from the inside surface of the outer retainer 11 and extends into the mounting groove 13. The protrusion 14 may be annular in shape. The top groove 15 is annular in shape and is formed in the flange and has a diameter smaller than the diameter of the mounting groove 13 and has multiple connecting ribs 151. The connecting ribs 151 are radially arranged in the top groove 15 and each connecting rib 151 connects the cap 10 and the flange and provides sufficient strength to the cap 10 and the flange.
With reference to
As the inner retainer 12 protrudes substantially perpendicularly from the outer retainer 11 and is slanted toward the outer retainer 11, the inner retainer 12 presses on the inner surface of the cup 20 and clamp the top edge of the cup 20 with the protrusion 14 to make the lid mounted on the cup 20 tightly.
When a user takes the cup 20 with the lid to drink something, the user gives a holding force to the cup 20 and may cause the cup 20 deformed in shape. The inner retainer 12 is abutted and pressed on the inner surface of the cup 20 to provide a resisting force to resist the holding force and overcome the deformation of the cup 20. Furthermore, the inner retainer 12 and the protrusion 14 clamp on the top edge of the cup 20 to keep the lid mounted on the cup 20 tightly and prevent the lid from falling off from the cup 20.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in detail, especially in matters of shape, size and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
