Description

VALVE MECHANISM FOR SWALLOWS CONTAINING SEMI-SOLID PRODUCTS.

[01] Field of the Invention.

[02] The present invention relates to a valve opening and closing mechanism for tube-type packages, commonly used for various semi-solid or pasty or creamy aggregate products, as with some cosmetics, including the topics and drugs.

[03] More particularly, the present invention is a set of means defined by two valves, one of which is a self-operating non-return check valve and is the first point of passage of the product from inside the tube into the mechanism. , while the other is a manual valve and defines the opening and closing of the package when extracting its contents. Therefore, the assembly is a means for a tube-like package to be hermetically sealed and, where necessary, a two-way rotatable cylindrical cap establishes opening and closing of the second valve by means of a small hole constituting the outlet of the product. This vertical hole, drilled in said cylindrical cap, is strategically positioned at the top of the mechanism and in the center of a slightly recessed area, so that said product can accumulate while the package is depressed until the desired amount is visible, at which time. The package is closed again only with a 90 ° rotational movement of said cover. The product is served at the top of the mechanism and is available to the user to be removed just by swiping a finger and then applied to the skin.

[04] State of the art.

[05] There are currently numerous packages with features similar to those mentioned above, as taught, for example, in the following documents: CN103826753A, US4987911, US5960802, US6745781, US6793431, US7309184, US7824124, US8226319, US8662856, US8714857,

US2013 / 108349, US2002 / 0014254, US2002 / 0090247,

US2003 / 0057236 and US20030057236. Of course each document describes a unique way in which a product can be applied, always to offer a more efficient way to handle, control and apply the product.

[06] There is no doubt that the mechanisms known for the above purpose are sufficient for the product to be applied correctly, however, those mechanisms that work with internal valves, although efficient, have been noted that could be considerably improved, because many of them use springs, spheres and all sorts of moving mechanical components, yet in the end a substantially complicated mechanism is defined and yet the delivery of the product does not take place in the desired way and consequently becomes a whole complicated industrial feasibility, both in the manufacturing process of the components, as well as in the final assembly of the same, making the set more expensive. [07] Notably the conventional devices do not have the desired efficiency at the time of opening and closing, the first being complicated and the second does not always perform a watertight closure, making possible leakage that, although it is extremely, causes waste and, Likewise, as it does not have an efficient seal, it can cause air to enter the packaging and over time the product characteristics are negatively altered, mainly by oxidation.

[08] In many cases the usual sets add up to the use of a lid or similar component that should be removed and placed during handling of the set, which also turns out to be somewhat uncomfortable.

[09] Objectives of the Invention.

[10] Provide two separate valves for closure and opening of the package, the first being an automatically operated first valve by pressing the tube, allowing the product to exit and enter the mechanism. This first valve is a non-return valve to prevent product return and air from entering the system, while the second valve is substantially a pin-shaped plug that tightly closes and opens the product outlet from within the mechanism.

[11] An easy-to-perform and efficient actuation to open and close the second valve is also objective, which is done in conjunction with a cylindrical cap and an internal cam system. The cover can be rotated 90 ° clockwise or counter-clockwise . Such movements establish closure and opening, that is, the two circular motions are transformed into alternating longitudinal motions that move up and down a kind of plunger which, on the one hand, through side pins is completed with support on the meat, while at its upper end it is integrated with a bung which closes and drills a hole in the top of the cylindrical shell over which the desired amount of product is served.

[12] With such operating characteristics, the package offers an advantageous packaging and mechanism suitable for the correct packaging of different semi-solid products, not only for the excellent means of preserving the product during storage and during consumption. its content is also gradual, but also because it offers an opening and closing mechanism defined by the short 90 ° rotation of the cylindrical cap that gives the tube superior finish and where the product is delivered to be applied to the user's skin.

[13] Therefore, many advantages are obtained with the package in question, making it unique when compared to conventional packaging used for the same purpose.

[14] As already mentioned, the above characteristics add up to all the means required for a semi-solid product to be properly conserved, notably those that must be kept isolated from the external environment, especially as regards air intake, which in some cases cause change negative, as many of them have increased reactivity in the presence of excess oxygen, causing damage to the original formulation, especially oxidation. In this condition, the whole set is ideal for the packaging of various semi-solid or pasty or creamy aggregate products, as with some cosmetics, including topicals and drugs.

[33] Detailed description of the invention.

[34] According to these illustrations and their details, more particularly figures 1 to 10, the present invention, VALVE MECHANISM FOR SEISOLID CONTAINERS, is characterized by the fact that its cylindrical mounting body (1) understand :

[35] - bottom means (2) of watertight coupling (3) of a usual tube-type package (4);

[36] - cylindrical, rotating coupling external means (5) for a clockwise and counterclockwise rotatable cylindrical cover (6);

[37] - internal means (7) for mounting two valves, one lower (8) and one upper (9);

[38] - the lower valve (8) being non-return check of the product;

[39] - the upper valve (9) is of the sliding type with vertical movement; and

[40] - upper means (10) for forming a sliding upper valve moving meat (11)

(9), the latter with means (12) for closing and opening a passageway (13) formed in the upper part of the cylindrical cap (6).

[41] As shown in Figures 11 and 12, the bottom seal-coupling means (2)

(3) of a usual tube-like packaging (4) are formed in the mounting body (1) by two vertical and concentric walls, one inner (14) and one outer (15) combined with one horizontal top wall (16), forming a circular neck penetration socket (17) (3), the upper edge of which is bifurcated (18) forming two concentric annular sealing sectors positioned against the inner side of the horizontal wall

(16) at this point a sealing washer is provided

(19), but also this socket includes two points of one axial and one radial, wherein the first is formed by an outer annular channel (20) below the locking bifurcation (18) for an annular protrusion (21) on the inner side of the wall (15) which further includes a tooth (22) at its lower edge which fits into a matching recess (23) on the corresponding part of the neck (3) so that the latter and the mounting body can be stably coupled without any movement therebetween.

[42] As shown in Figure 13, the external means (5) of the swivelly coupling mounting body (1) for the cylindrical cap (6) are defined by several annular projections (24), one of which is larger in diameter (25) which, within the cover (6) is a socket (26) practiced on vertical spacer ribs (27). In this manner, said annular protrusion (25) functions as a circular rail which allows the cap (6) to be rotated in both directions.

[43] Referring to Figures 14 and 15, the internal means (7) for mounting the two valves (8) and (9) are formed together with the concentric wall (14), whose lower end has a closing wall ( 28) with through-openings of the product (29), above which the first check valve (8) is mounted, while at its upper end said concentric wall (14) has a slightly larger diameter extension (30) which, in addition to forming an internal intermediate step (31), also forms a housing for the second valve (9).

[44] Still with reference to figures 14 and 15, the lower valve (8) consists of a flexible seal

(32), washer-shaped, fitted to an inner pin

(33) emerging from the central part of the closure (28), which covers all openings (29), where it is flexible enough to establish their opening when the tube (4) is pressed, ie when there is internal pressure said seal is flexed in order to open the openings (29) and, when there is no pressure, said seal is accommodated over the openings (29) and prevents the return of the product.

[45] The upper valve (9), also shown in detail in figures 14 and 15, is a tubular piston having sliding lip ends (34) and

(35) and is slidably mounted within the inner concentric wall (14), as well as having two radially outwardly opposing pins (36) aligned for sliding engagement with the cams (11) and furthermore the upper end of said piston has the means (12) for opening and closing the passage (13) of the cover (6) internally formed by a central bung

(37), the base of which is integrated with the internal diameter of said piston without interrupting the passage of the product therein.

[46] The upper end of the piston (9), as further illustrated in Figures 14 and 15, is guided in its vertical movement by a concentric wall (38) within the tubular cap (6), which wall has a diameter and thickness. coincide for alignment on the step (31), and still this same wall

(38) Includes at its bottom edge two vertical tears opposed to each other (39), in which the radial pins (36) of the piston (9) are engaged, so that the latter can receive the two-way turns of the cap (6) and, concomitantly, said pins (36) slide in the meat (11) and at this moment, the plunger adds one more movement, now vertically, up or down, closing or opening the passage (13) of the product through its bung (37).

[47] The top face of the cap (6) has a semi-spherical recess (40) to accommodate the desired amount of product to be applied.

[48] As can be seen from the above and illustrated, the operation of the assembly is very simple indeed, it even achieves all those advantages mentioned above thanks to the constructive details adopted for the internal mechanism, figure 16, which includes two valves (8). ) and (9). In this figure the passage (13) is closed by the spigot (37). In this condition the pins

(36) of the piston (9) is at the end and the highest point of the meat (11), consequently, the spigot (37) is also in its highest position and completely closes the passage (13). In this position the product does not come out even if the tube (4) is accidentally depressed. In Figure 17 the situation is reversed, in this position the valve (9) is open, that is, as already said this opening is made only with a short 90 ° turn of the cover (6), which in turn is connected to the ends (36) of the valve (9), which allows it to be rotated in two directions and thus these ends slide over the meat (11) now to the lowest position, moment in time. that the spigot (37) moves away releasing the passage (13). In this position by pressing the tube (4) the semi-solid product forces the passage in the lower valve (8), at which time it flexes and allows the flow of the product through passage (29) flooding the interior of the valve (9) and from it. it passes through the passage (13) to accumulate in the recess (40) over the cover (6), remaining in a stable position to be removed only by passing the fingertip. The packaging is closed only with another 90 ° reverse rotation of the cover (6), after which the entire internal assembly returns to that position shown in figure (16), thus avoiding air intake and, consequently, the product is properly maintained.

[49] Advantageously two valves are combined

(8) and (9), one with automatic operation that prevents product return and air from entering the system, while the other is operated only with 90 ° turns of the cover (6). With such operating characteristics, the package offers an advantageous packaging and mechanism suitable for the correct packaging of different semi-solid products, especially those that must be kept isolated from the external environment, especially with regard to air intake, which in some cases causes negative alteration of the product, as many of them present increased reactivity in the presence of excess oxygen, causing damage to the original formulation, mainly oxidation. In this condition, the whole set is ideal for packing various semi-solid or state-of-the-art products. pasty or creamy aggregation, as with some cosmetics, including topicals and drugs.
