Brief Patent Description - Full Patent Description - Patent Application Claims
CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application is a continuation-in-part of PCT application Ser. No. PCT/MX2006/000017, filed Mar. 14, 2006, to which priority is claimed, and which claims priority to Mexican Application No. PA/u/2005/000066 filed Mar. 14, 2005, to which priority is also claimed. This application also claims priority to Mexican Application No. PA/u/2006/000196 filed Sep. 29, 2006. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] This invention relates to a can lid that allows a person to drink from a hygienic can. Likewise, it refers to a can lid that allows advertising media by both sides of the lid. [0004] 2. Background Art [0005] Millions of canned beverages, such as sodas, beers, teas, juices and many more, are sold each year and drank by millions of different persons. In fact, it is so much so that it would be difficult to believe that a person had not drank a canned beverage during the last year. [0006] Currently, the health of the consumer is not protected by the producers of canned beverages, because as the can is always kept outdoors, either in its transportation and storage, it is contaminated by dirt, liquids, organic disposals of animals that live in the warehouses, and an endless number of organic and inorganic contaminant elements that, as much as one cleans or disinfects the surface that will contact the lips, a real hygiene condition cannot be guaranteed. [0007] These problems have been tried to be resolved in several occasions. For example, the U.S. Pat. No. 6,450,358 describes an accessory in the shape of a second lid for the "pop-top" type of cans. The "pop-top" cans are those whose upper part has a lever that creates a force against a pre-scored opening of said upper part of the can, in order to open the can and be able to drink the contents of the same. In the invention of the above-mentioned patent the cap attachment is formed of a liquid-impervious, elastically resilient material that has a skirt with a radially inwardly directed lip at its outer periphery and with a drinking port defined completely through its structure. The drinking port is spaced radially inwardly from the periphery of the cap attachment for alignment with the drinking opening in the pop-top beverage can. [0008] Usually, the conventional beverage cans are made of aluminum, iron or any other metal, with a cylindrical shape in general, with upper parts that are partially flat, and with hollow lower parts. The upper part of the cans is generally round, the side walls of the can are rolled with the upper part of the outside wall of the can, in order to seal the internal contents. [0009] Another intent to solve the problem in question, is the U.S. Pat. No. 6,457,597. Said patent resolves the aforementioned hygiene problem by means of a cap and a straw, where the cap includes a ring in its lower part that adjusts to the edge of the upper part of the can. This invention solves the hygiene problem, but the production of the same is expensive and not very useful. [0010] Another invention that solves this same problem, is U.S. Pat. No. 5,947,324. This invention provides an adapter in the shape of an upper part of a bottle, for the consumer to drink from the can, as he/she was drinking from a bottle. The adapter may be detached and fastened at any time. One of the objectives of said invention is to provide greater hygiene to the product being consumed, and such is achieved through the adapter. Now, the problem with said invention is that when the can is poured in order to consume its product, it touches the metal of the upper part of the can, thus the organic or inorganic contaminants that could be in the upper part of the can will be in contact with the liquid. [0011] Another intent to solve this problem is the U.S. Pat. No. 4,951,344. This device cleans contaminants of the upper part and the upper side part of a can. Nevertheless, this device is very expensive to manufacture by the packing company or for the manufacturer of the can. Additionally, it is not practical to be carrying with such cleaning device. [0012] There is also the request of Mexican utility model number PA/u/2004/000114, granted under Utility Model number 1441, of the same inventors of the invention herein. The invention of the request, also has as objective to keep the lower part of the beverage can free of contaminants. One of the disadvantages that the invention mentioned above presents, is the lack of seal of the lid, same that this invention resolves, allowing that particles and substances bigger than particles and not much hygienic are introduced, same problem that this request resolves, as will be later explained. Additionally, the way in which the lid is attached to the can is different, providing even another hygienic advantage over the prior art. Another advantage of this invention versus the utility model requested, is the detachability of the lid, once the guarantee seal is broken, as will be later explained. Finally, another advantage of the invention herein is that the part where the lower lip is placed to drink, is also free of contaminants, as the guarantee seal is sealed in its lower part. [0013] There is also the request of Mexican utility model number PA/u/2005/000066, conferred with utility model number 1394 of the same inventors of the invention herein. The subject of this utility model also has as purpose to maintain free of contaminants the upper part of the beverage can. One of the disadvantages present in the utility model mentioned above, is the way in which the lid seals, a problem, which the invention herein resolves. This invention, by means of its technical configuration, does not allow the entry of particles and substances that are not very hygienic, by means of its novelty sealing, as it will be explained further herein. Considering that the technical configuration of the sealing of the lid is modified, the way in which the lid is attached to the can is different, providing another hygienic advantage over the prior art. Another advantage of the invention herein versus the utility model mentioned above, is the detachability of the lid once the guarantee seal is broken, as will be explained later. Finally, another advantage of the invention herein is that the part where the lower lip is placed to drink, is also free of contaminants, as the guarantee seal is sealed in its lower part. [0014] Thus, one of the objectives of this invention is to keep the upper part of the beverage can free of contaminants. [0015] Another of the objectives of the invention in question is to keep the upper side parts of a beverage can free of contaminants. [0016] Even another objective of the invention herein is to keep a reasonable cost for the producer, the distributor or the packager, depending on who produces the invention in question. [0017] Another objective of this invention is that the same can be disposable. [0018] Another objective of this invention is that such invention is not to be an obstruction for the consumer when he/she is drinking the liquid from the can. [0019] Additionally, this invention has as purpose to provide the consumer a guarantee that the lid is not broken, and therefore there are no contaminants in the upper area of the can. [0020] Another objective of this invention is that the sealing lid may be easily detached. [0021] The invention herein also has as its purpose to provide the consumer the guarantee that the lid has not been broken, and therefore there are no contaminants in the upper area where the lower lip contacts the can. [0022] Other objectives of the invention will be made evident along the description of the invention. Continue reading about Hygienic beverage can lid...
