Magnetic drinking cup

Abstract

The present invention is directed to a magnetic drinking cup, containing magnetic and metal components. Many cups known in the prior art have screw top lids, which have tight and narrow crevices making the cleaning process cumbersome. If not cleaned immediately after use, it becomes challenging to remove the debris remaining in the cup, and in the crevices of the lid. These crevices create a trap for bacteria and mold. The same issues can arise with reusable straws. There are not many tools on the market that can clean a straw thoroughly from top to bottom. If all contents are not removed from the straw, then it becomes a petri dish of bacteria; and if moisture remains, then mold will have the ability to grow. This invention provides fewer areas where bacteria and mold can flourish due to a magnetic seal instead of a screw top seal.

(14) FIG. 2 is a front perspective view of the magnetic drinking cup assembly 100 in a closed position. The lid 30 can be pressed down to close the cup, such that its border 35 overlaps with the cup's exterior upper edge 15, mating the lid with the cup. In this closed position, not shown is the magnetic ring, which is sitting inside of the cup 10 on an indentation behind the cup's upper edge 15. Reusable straw 40 is shown as inserted into the straw hole enabling a user to drink from the cup in this position.

(15) Not shown in this Figure is a metal strip, which is embedded within the lid's border 35. Also not shown, is a magnetic strip enclosed within the magnetic ring. The lid and the cup are securely mated together through a magnetic attraction, which is further explained in the sections to follow.

(16) In the current embodiment, the cup is constructed of a plastic material. However, in other embodiments, the cup can be constructed of silicone and glass. The lid, straw, and metallic ring are constructed of silicone material to enable maximum elasticity. Additionally, in the current embodiment, the straw's height is 9.5 inches, while the cup's height is 8 inches. The components of this invention can vary in range of elasticity, as well as, in thickness and in size. Magnetic drinking cup assembly can be constructed with any material having similar or more proficient elasticity, magnetic, and adjustability properties, as would be well known to those skilled in the art.
