DISPOSABLE PLASTIC CUP LID – A BRIEF INTRODUCTION TO THE PLASTIC CONTAINE
The invention refers to a disposable plastic cup lid that is employed to safely close a plastic bottle or cup. The disclosed invention includes a disposable plastic cup lid having an elongated opening on one side having inwardly extending edges thereof, a second edge extending outwardly out of the inner side of this opening, and in conjunction with the opening, a band having interlocking tabs that are glued to the outer surface of this lid. The tabs of this reusable cup lid cooperate to close the opening of the cup even if the contents of the bottle have been emptied.
This invention provides an improved means of procuring a cup even when it is empty. The present invention has the advantage that there is no need for extra equipment to manufacture the disposable plastic cup lid. The invention also includes means to enlarge the opening of the cup by inserting a plurality of beads into the opening of the cup in such a way that the plurality of beads that are inserted in the cup causes the opening of the cup to expand to the point that it fits over the entire rim of the bottle or other container. With these and other features, the present invention can be considered to be a unique improvement over the earlier methods of filling plastic containers and bags.
The present invention provides a means for securing small round or oval shaped drinking cups to a wall by means of a conical configuration. The conical configuration of the plastic container lid enables the lid to be slid or pushed back easily into its original position on the cylinder. This means that the conical configuration of the plastic container lid is a unique feature that has definite advantages. One of these advantages is that the present invention provides a means for securely securing a small round or oval shaped drinking cups to a wall by means of a conical configuration. This means that the present invention provides a means for securely securing a small round or oval shaped drinking cups to a wall by means of a conical configuration.
In the case of such a plastic container with a single lid, the lid could be slid up over the entire rim by means of a ball or by means of an olefin wing or by a series of olefin wings. There was always a problem with the fact that the lid often popped up over the rim of the container because the ball that held it up was generally known to be weak and frail. It also generally took some time to get the ball rolling along the rim so that the lid would properly move up and down. In this regard, the present invention provides a means for securing a multiple size lid based on the present invention.
The present invention involves the use of a series of conical or circular disk shapes which are each pushed into a series of hole or by a conical hinge means. This means that the plastic lids can be moved up and down in accordance with the need. The plastic containers with a single lid could be made of any suitable material depending on the need. The plastic containers with a multiple size lid according to the present invention could be used for storing any suitable material, including but not limited to, sugar, beans, cereal, sauces, or fruits and vegetables.
The plastic lids as disclosed in the patent are provided with a lip surrounding the lower edge of the opening, either by means of a conical or circular disk or by a series of conical or circular disk shapes. These devices could be kept open by means of a spring or a hydraulic device that could be manually operated or could be operated automatically. Such a device could also be used as a thumb depressor so that the thumb can insert a finger in the hole or by a suction so that the finger or the thumb of the user is trapped inside the device. All of these devices can be operated either electrically or mechanically. Thus the range of applications of this particular type of disposable container is only limited by the creativity of the inventor.
