The proposed invention relates to a bottle stopper with a built in light specially developed to correctly visualize the state of the internal fluid and for liquids with bubbles verify the quantity, the quality and the size of the bubbles.
As an added side effect, the aesthetic appearance can be considered.
The field of the invention is the industry of bottle stoppers manufacturing and the industry of electrical and electronic component manufacturing.
It is known since ancient times the use of all kinds of stoppers of every type to seal liquids in bottles for their transportation and storage.
In the archaeological museums there are pieces used to close vessels, with an abundance of forms, set-ups and decorative elements on top.
Since the invention of glass, bottle stoppers have been mostly made of cork for wine and of plastics for spirits, featuring many different shapes to put forth technical solutions to problems, such as non-refillable stoppers, selective air output stoppers, anti-drip stoppers and many more.
Within the research done on background art, a distant precedent has been found.
This is the WO2014196484 patent titled “Cork with light” with Egg Cube INC Japan filing as applicant and Sasakitakayuki (JP) as inventor, and date of application 2014 Dec. 11.
“The purpose of the present invention is to provide a cork with a light which can preserve sufficient rigidity in the cork proper, and can be reused. This cork with a light comprises a hollow cylindrical part (12), a retaining part (13), a light source unit (14), and a connecting part (15). The hollow cylindrical part has an inner circumference radius (12a) which is larger by a prescribed gap radius than an outer circumference (11a) of a coin cell (11), and is electrically conductive. The retaining part has a thickness (13a) which is thinner than the gap, is mounted upon the outer circumference face side of the coin cell, and is electrically insulated. The lateral light source unit has one electrical wire (14a) which is electrically connected to a lower electrode (11b) of the coin cell, and another electrical wire (14b) which is electrically connected to the inner circumference face of the hollow cylindrical part. The connecting part has one conducting wire (15a) which is electrically connected to the inner circumference face side of the hollow cylindrical part, and another conducting wire (15b) which is electrically connected to an upper electrode (11c) of the coin cell.”
After carefully reading said patent, differences between both embodiments can be noted, among which we can highlight at least the following:
After an exhaustive research of the background art, no more noteworthy background references have been found and none are known to contain the specifications, novelty and benefits associated with this patent expected to be granted.
The proposed invention relates to a bottle stoppers with a built in light specially developed to correctly visualize the state of the internal fluid and for liquids with bubbles verify the quantity, the quality and the size of the bubbles.
As an added side effect, the aesthetic appearance can be considered.
The stoppers of the invention is formed starting from a standard stopper, on which a inner hollow is carved so that it can accommodate an air-tight capsule formed into a cylinder with a rounded top part and where a battery and an electronic circuit that conducts the energy from the battery to a LED light can be seen, being said air tight capsule sealed on the bottom by means of a see through glass pane.
So that the air-tight capsule is not displaced in position within the stopper, several solutions have been various.
One of them is a set of flexible pins that are received within notches made on the inner walls of the stopper once it has been carved.
In another, the inner walls of the stopper are carved without any notches and the air-tight capsule is perfectly secured within the hollow carved by means of small pyramids at the top and sides of the air tight capsule and due to the pressure applied at the time of inserting the stopper into the bottleneck of the bottle leaving said pyramids stuck on the inner face of the hollow carved in the stopper.
For a better understanding of the invention, a sheet of drawings is attached in which the following can be seen:
In these figures, identical elements are referenced equally, among which the following can be told apart:
The proposed invention relates to a bottle stoppers with a built in light specially developed to correctly visualize the state of the internal fluid and for liquids with bubbles verify the quantity, the quality and the size of the bubbles.
As an added side effect, the aesthetic appearance can be considered.
In a preferred embodiment of the invention the referenced stopper is formed from a standard stopper (1) preferably made in cork, to which an inner hollow has been carved inside (2) so that it can house an air tight cylindrical capsule (4) with a rounded top part and within which the following elements can be discerned:
A battery (5), preferably lithium because of the capacity and low weight, an electronic circuit (6) that connects the electrical power from the battery to a light providing LED (7) being said air tight capsule (4) sealed on the bottom by means of a see through glass pane (9).
So that the air-tight capsule (4) cannot be displaced out of position within the stopper, several flexible pins (8) have been provided that are housed within notches (3) made on the inner walls of the stopper (1) once made hollow inner space has been made (2).
The flexible pins (8) are completely attached into the grooves (3) and thus the air tight capsule (4) stays fully set within the cap when the assembly is inserted into the bottleneck of the bottle due to the tremendous pressure that is generated in this operation.
In another preferred embodiment, no notches are done to the inner walls of the stopper (1) after the inner hollow (2) has been made.
In this case, the air-tight capsule (4) has small pyramid-shaped protrusions (10) on its perimeter and on the top side.
Because the pressure applied at the time of inserting the stopper within the bottleneck of the bottle, said small pyramid-shaped protrusions (10) are driven deep into the inner face of the stopper thereby immobilizing the air-tight capsule inside the stopper.
Having sufficiently described the nature of the invention, as well as how to be implemented, it must be stated that the provisions referred to above and shown in the accompanying drawings are susceptible to change in detail as long as they do not alter the fundamental principles set out in the paragraphs above and summarized in the following claims.
