Description

Hermetic container valve

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a valve for airtight container that in one position allows the air circulation communicating inside the container or container with the outside and in another position provides a closure by way of cap tightly closing the container.

It is applicable to containers or containers that are usually introduced in a microwave oven to heat food located inside the container, so that when heated the food increases the pressure inside the container due to the gases that must be released precisely through the valve to avoid accidents, being able to explode the container but that release of gas pressure occurs.

When the food or part of it cools, it can be stored in the refrigerator, closing then the valve.

Background of the invention

Airtight containers introduced into a microwave oven, in order to heat the food inside, It is necessary to remove the cover beforehand or leave it slightly raised to allow the output of the gases generated in the interior and thus avoid possible accidents, since an accumulation Excessive gases can cause the explosion of the container.

Description of the invention

In order to achieve the objectives and avoid drawbacks mentioned in the previous sections, the invention proposes a valve for airtight container that solve the problems through a simple valve that is located on the lid of that container commonly used to heat Foods that are introduced inside.

The valve is characterized in that it comprises a main body of cylindrical-tubular section, whose upper end joins perpendicularly to a flat body, while the lower end is finished off in a perimeter projection exterior as a stop.

Other features of the invention is that the Main body wall is affected by at least one groove longitudinal that reaches from the free end of the body main to a characteristic superior thickening located outwardly and established in the highest part of that body principal.

The valve is complementary to one tubular section to the top, tubular section that has a flange internal perimeter where the valve stops when it is in an open position to allow the gases to escape from the food when heated, precisely through the groove longitudinal, thus avoiding an increase in pressure in the inside the container or container.

To place the valve in the open position, the it moves perpendicularly outward with respect to the cover until the lower end of the main body protrudes butt against the inner flange of the tubular section of the top.

Instead, to reach the closed position, the valve also moves in the same direction but in opposite direction, that is, into the container, with which the thickening adjacent to the flat body will also butt against the annular flange also adjusting in addition to a perimeter widening established inside the section Tubular cap above the perimeter flange.

The closed position is suitable, for example, when the container or container is stored with food inside from the fridge

On the other hand, the tubular section of the lid is is located in correspondence with a recess of the aforementioned lid, so that in the closed position of the flat body of the valve is flush with the lid itself.

The advantages of this invention are based on its two positions, open and closed, and in its simple form of driving. In this way, in the closed position it forms a closure Hermetic together with the lid and the container for a perfect food preservation, and in the open position allows the exit of the gases when heating the food, with what not only prevents it from exploding due to excessive pressure inside, but also being mostly covered helps a better cast of heat, reducing cooking time and consequently the energy consumption.

Next to facilitate a better understanding of this descriptive report and being an integral part of the same accompany some figures in which with character illustrative and not limiting the object of the invention.

Description of the preferred embodiment

Considering the numbering adopted in the figures, the valve for airtight container is determined from of a cylindrical-tubular main body 1 embedded within a tubular section 2 that is part of a lid 3 which closes the mouth of the container 4. That tubular section 2 is located in correspondence with a recess in the form of a cap spherical 5 that forms an integral part of the lid 3.

The main body 1 is integral with its end upper of a circular body 6 topped by a rib perimeter 7, while the lower end is finished off in a perimeter projection 8 as a stop that limits the opening of the valve when contacting with an annular flange 9 located inside of the tubular section of the lid 3, while in position closed, an upper thickening 10 of that main body 1 is fits in an annular widening 11 located at the end upper part of said tubular section 2 of the cover 3, at the same time as thickening also stops against the annular flange mentioned previously.

The main body 1 incorporates a longitudinal slot 12 that allows communication inside the container with the outside when the valve is in position open This allows the exit of gases and release of the pressure from inside the container or container when heat the product housed in a microwave oven container.

The aforementioned slot 12 reaches from the free edge from main body 1 to upper thickening 10.

In this way, by pushing the valve towards the inside of the container, the upper stop thickening 10 seats against the ring flange 9 fitting at the same time in the widening 11, thus producing a tight seal.

Instead, by pulling out the set of the valve, taking it with the fingers of the flange or rib rounded 7 of the flat body 6, the valve moves until the bottom stop 8 contacts the ring flange 9, allowing thus the circulation of gases from the inside of the container to the outside through the longitudinal groove 12.
