Definitions
- the present invention refers to a retention valve suitable for use at the outlet point or outlet spout of the most varied packaging for easy-flowing products, whether they are: cosmetics, pharmaceuticals, foodstuffs, including lubricants and other chemical products that, for one reason or another, are dispensed in considerably reduced quantities.
- the present check valve is an independently developed device, with means to be simply fitted and locked next to the product outlet, this outlet in the form of a simple hole or in the form of a spout, where it has as main functions: closing and opening the outlet (spout), avoiding splashes and preventing air from entering.
- the dispensing head or other corresponding part of the packaging includes various valve systems, all of them designed to open when the dispensing head is activated or when the packaging is pressed, allowing a certain amount of product to flow easily can come out through the dispensing spout of the package.
- This way of serving a quantity of product is already known and currently there is a range of specific constructions for each case or product.
- the residual part although small, remains in an undesirable position, capable of producing splashes and drips, in addition to other more serious inconveniences, particularly with regard to the influences of the external environment, since this part Residual waste is an easy target for the effects produced by the air and ambient humidity, such as: dryness and contamination by the most varied pathogens. As if these inconveniences were not enough, the residual part can undergo other significant alterations, since it is still possible to occur different alterations of the original characteristics of the product or of the formulation itself, mainly oxidation, drying or humidification.
- valve mechanisms in the generic form of pistons or even membranes, to eliminate the inconveniences listed above, however, it was observed that each valve component is closely integrated with the corresponding parts of the dispensing spout or at the end of the product outlet, as shown in documents US7578417, US7934667, US8245884 and US8261952, cited here only as an example, where it can be seen that the "valve” is mounted directly at the end of the product outlet and, its constructive details are integrated with other constructive details of the outlet or dispensing spout, thus, each valve is specially developed according to the packaging where it will be used and according to the product to be dispensed, consequently, it becomes difficult to make such valves with a construction standardized so that it is compatible for use in other different packages.
- the check valve which is also a protection valve, presents a simplified construction and capable of defining "a standard model" ideal to be used in different packages and different products to be dispensed , a detail not found in the state of the art.
- the outlet of the product whether in the form of a dispensing spout or not, has a predominant detail which is a passage in the form of a circular hole which, in addition to allowing the flow of the product, constitutes a cavity for fitting and mounting the check valve.
- the present invention adopted as its main objective to define a "cylindrical capsule" type check valve sized to be simply fitted with interference in said passage or circular hole predominantly existing in the outlets or dispenser spout of the package.
- the simple interference fit may or may not include projections or male and female fittings for permanent locking of the aforementioned cartridge valve.
- the present cartridge valve is capable of being used in different dispensing packages, regardless of the characteristics of the volume to be dispensed in each actuation, thus characterizing a standard model of check valve that, still, just by varying its sizing, increases its range of application even more, that is, it becomes suitable for dispensing intimate quantities of product or considerably large quantities, consequently, the same check valve can be used in packaging for different easy-to-flow products, whether they are: cosmetics, pharmaceuticals, foodstuffs, including lubricants and other chemical products that, for one reason or another, are dispensed in varying amounts.
- Another objective of the present invention is the realization of a check valve with a reduced number of monomaterial parts and with simple construction and efficient operation.
- Another objective of the present invention is to characterize only three components that define the valve itself, all circular, with an external one defined as an intermediate body, an internal one defined as an obturator and a posterior one defined as a flexible support screen.
- the intermediate body constitutes the obturator guide and its anterior end constitutes a sealing seat, while, at the posterior end, it includes a fitting for the support screen which, in turn, has a dome that configures a flexible sector or spring for said obturator.
- this valve is simply fitted and fixed in the product outlet hole or in the dispenser spout hole, where it is kept for automatic operation, that is, when internal pressure occurs, the product flow finds the present valve in the dispenser outlet.
- the internal pressure caused by the product causes the obturator to be displaced in the same direction and, with that, the obturator sealing head moves away from the seal seat, allowing the product to exit until the moment the pressure internal ceases to exist.
- the obturator returns to its original position, thanks to the spring of the sieve whose elastic memory pulls the said obturator backwards to its original sealed position, that is, until its sealing head is seated in the sealing seat, closing completely exiting the product, where the residual part remains completely protected from the external environment, avoiding splashes, oxidation and all sorts of alterations that the environment may cause.
- valve in question has constructive characteristics that make it "standard”, that is, the valve itself is housed in a cylindrical capsular body, which makes its insertion and fixation possible in the circular outlet of different dispensing packaging for easy-flowing products, whether they are: cosmetics, pharmaceuticals, foodstuffs, including lubricants and other chemical products that, for one reason or another, are dispensed in specific quantities.
- FIGURE 01 represents an angle view of the assembled valve
- FIGURE 02 shows another perspective of the valve mounted, however, at a posterior angle
- FIGURE 03 illustrates an exploded perspective in anterior angle showing the details of each component of the valve
- FIGURE 04 is also an exploded perspective, however, in a posterior angle showing other constructive details of each component of the valve;
- FIGURE 05 shows one of the "A-A" section indicated in figure 1, showing the valve completely assembled and fitted in the circular outlet of a usual dispenser package;
- FIGURE 06 represents a view of the same section illustrated in the previous figure, however, in this case the valve is schematically shown in the open position.
- a RETENTION VALVE FOR VARIOUS PACKAGING is characterized by comprising a capsular body (1), which configures the outlet conduit for the product to be dispensed, this body having the external diameter, equipped with means (2) of fixation inside the outlet in the form of a circular hole (F) of a usual dispensing package (E), while in its internal diameter it is housed, slidingly, an obturator (3) movable longitudinally, as well as its front end has means (4) of watertight sealing for the obturator (3), while its rear end is softly engaged in the center of a flexible sieve (5) and, at this point, said sieve has means to keep said obturator (3) tensioned backwards in order to keep the means closed (4) watertight closing, where the closing pressure is overcome by the internal pressure established inside the outlet in the form of a circular hole (F) when activating the usual dispensing package (E).
- the fastening means (2) inside the outlet in the form of a circular hole (F) of a usual dispenser package (E) are formed by a circular collar (6) with a central channel (7) of engagement in a circular thread (8) existing in said outlet in the form of a circular hole (F), and this fixation can also be carried out by simple mechanical interference.
- the capsular body (1) has the ends of its internal diameter defined by staggered sections, in which the anterior one that defines the sealing means (4) has two steps, both greater than 90°, an internal one (9) and an external one that configures the cone-shaped seal seat (10) for seating the corresponding part of the obturator (3), while at the opposite end of said capsular body (1) there is another step at an angle greater than 90° (11) for seating the sieve flexible (5) .
- the obturator (3) in a single piece, comprises an intermediate section finned longitudinally (12), a front head in the form of a bung (13) and a posterior cylindrical tip with a coupling terminal (14), in which the longitudinally finned intermediate section (12) is slidably adjusted to the internal diameter of the capsular body (1), while its front head in the form of a bung (13) has the shape of a circular tablet with a truncated external diameter that rests on the conical sealing seat (10) of the capsular body (1), and also the posterior tip of the coupling terminal (14) of the obturator (3) constitutes irreversible engagement in the spring center of the flexible screen (5).
- the flexible sieve (5) is defined by an annular section (15), whose external diameter is conical cooperating for seating on the step (11) of the capsular body (1), and the posterior side of the annular section (15) it is extended in the form of a hollow dome defined by flexible links (16) that culminate in a circular center (17) with a penetration hole (18) with interference from the rear coupling tip (14) of the obturator (3).
- the assembly and operation of the present check valve are substantially simple, that is, the assembly takes place with only the insertion of the assembly in the outlet or outlet hole (F) of the product to be ejected by the usual dispenser (E).
- the outlet (F) the product begins to flow towards the sieve (5) and runs through the entire interior of the valve, however, when it encounters the bung (13) this pressure forces the bung (3) out.
- the product only stops flowing out when the internal pressure is lower than the flexibility strength of the sieve (5), that is, when the internal pressure is lower or ceases to exist, the obturator (3) returns to its original position, thanks to the spring of the sieve whose elastic memory pulls the said obturator even backwards to its original watertight position, completely closing the product outlet, where the residual part remains totally protected from the external environment.
