Description

[Technical field]

[0001] More specifically, the present invention relates to a specially designed mechanism for varying the outlet flow of a semi-solid product dispensed from a conventional package. This variation in flow is determined by the valve details of the cartridge, and three embodiments are defined in which, depending on the valve, the outlet flow of the product can be changed to a drip, trickle or spray.

[0002] The cartridge of the present invention is therefore a complementary mechanism developed to be mounted directly at the nozzle outlet area of ​​a known actuator of a conventional package. The actuator is combined with a pump-type mechanism for the delivery of the product conventionally contained in the package. By pressing the actuator, the pump-type mechanism is activated, which forces the product out until it is dispensed from the nozzle of the actuator. This arrangement allows a consistent amount of product to be dispensed with each actuation of the actuator, varying the outlet flow during dispensing.

[0003] In many cases, the same packaging, the same dispensing mechanism, the same actuator are used for different products that, for one reason or another, must be dispensed in different flows: drip, trickle and spray.The cartridge of the present invention therefore aims to maintain the same structural characteristics of the packaging and its actuating mechanism, simply by adapting the corresponding cartridge to the desired flow type. [Background technology]

[0004] Currently, there are numerous packages that are specifically designed to allow the controlled delivery of a measured amount of a semi-solid product. Such packages are configured in many different ways, some simple and some more sophisticated, one of which stands out for utilizing a pump-type internal valve mechanism with a plunger driven by an actuator that also includes the outlet nozzle of the product, as taught, for example, in International Application PCT / BR2020 / 050025 and US Pat. No. 10,512,928, cited here only for illustrative purposes of the use of a plunger or pump to allow the delivery of a measured amount of product.

[0005] Thus, packaging of this type having an internal mechanism for dispensing the product usually works by pressing an upper head having the appearance of an operating button. Said button is usually called an "actuator" and when pressed, it activates a pump-type mechanism which forces the product out until it is dispensed from the actuator nozzle. This mechanism ensures that a fixed amount of product is dispensed each time the actuator is operated.

[0006] There is no doubt that pumping mechanisms are sufficient to deliver the correct and desired amount of product. However, said pumping mechanisms generally have specific details to meet the specific flow characteristics of each product to be delivered. Because, for one reason or another, products must be delivered in different flows, not only due to viscosity but also other factors. The most well-known flows are defined as drip, trickle and spray. Hence, more diverse pumping mechanisms are required to meet the specific flow characteristics of each product to be delivered.

[0007] Furthermore, conventional packaging of this nature has other drawbacks, the most significant of which is that the outlet nozzle remains open, so it is directly affected by the outside environment, especially the ingress of air. More specifically, it can be said that there is no barrier between the outlet nozzle and the product's pump-type mechanism to prevent the ingress of air. In this situation, the product remaining between the nozzle and the pump mechanism is mixed with air from the outside environment, which leads to oxidation of the product, so a large amount of preservatives are usually used to prevent oxidation.

[0008] Thus, degradation of the product remaining between the nozzle and the ejection mechanism is due to the absence of a valve member at the product outlet, i.e. at the end of the nozzle, and therefore all product remaining from this point up to the sealing valve of the ejection mechanism is subject to contamination by the outside air, resulting in a vicious circle of degradation of the dispensed product, as in many cases a remainder of the product may "represent the next amount to be dispensed", some of which always remains in the actuator area. Needless to say, degradation is understood as the various effects caused by the influx of air into the nozzle area, which can cause significant changes in the product, such as microbial contamination, drying, oxidation, spillage, etc. Summary of the Invention

[0009] The objective of the cartridge of the present invention is to ideally improve on the complementary mechanism developed to be directly attached to the nozzle outlet area of ​​any known actuator of a normal packaging, the complementary mechanism having the function of varying the outlet flow of the dispensed semi-solid product, the variation of this flow being determined by the detailed structure of the valve of the cartridge and being defined in three embodiments in which the outlet flow of the product varies: drip, trickle and spray.

[0010] Another object of the present invention is to provide a valve means for sealingly closing the product outlet nozzle, i.e., a sealing valve that closes precisely at the end of the product outlet, logically preventing the ingress of outside air and eliminating the drawbacks of conventional packaging, and completely eliminating the ingress of air and the remaining part of the product that may come into contact with the outside air, thereby preventing the deterioration of the product due to the ingress of air into the nozzle area and eliminating any significant deterioration of the product, such as microbial contamination, drying, oxidation, spillage, etc.

[0011] Another object of the invention is a cartridge operable with any known actuator and conventionally combined with a pump mechanism for dispensing the product contained in the package. Thus, by pressing the actuator, the pump mechanism is activated, forcing the product out until it is dispensed from the nozzle of the actuator. This arrangement allows the outlet flow to be varied to dispense a constant amount of product each time the actuator is pressed.

[0012] Another object of the present invention is to allow the use of the same packaging, the same dispensing mechanism and the same actuator for different semi-solid products which, for whatever reason, must be dispensed in different flows: drip, trickle and spray. Thus, the cartridge of the present invention is precisely designed to maintain the same structural characteristics for the packaging and its actuating mechanism, and only the cartridge can be adapted to the desired format of the semi-solid product to be dispensed.

[0013] Another object of the present invention is to enable the same packaging to be used for the dispensing of a substantially wide range of products in different cohesion states, such as, for example, various cosmetic products, whether cosmetic, therapeutic or both, some of which are known as functional cosmetics, having an action equivalent to that of medicines, in particular liquid, oily, creamy and semi-solid forms in general.

[0014] It is also an object of the present invention to enable the same cartridge assembly to be used for "push without pump" type packaging, i.e., packaging in which, when the body of the package is pushed, sufficient internal pressure is generated to actuate the cartridge, which similarly dispenses a fixed amount of the product contained in the package.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] According to these figures and details of the present specification, in particular FIG. 1, the valve cartridge for actuators of various packages, which is the invention, is an independent and complementary valve mechanism (1) developed to be mounted directly in the interior area of ​​the outlet nozzle (2) of a known actuator (3) of a conventional package (4), which is conventionally associated with a pumping mechanism (5) for dispensing a product (P) contained in the package (4), thus the package having a sealed upper closure (6) constituting a body for accommodating the dispensing pumping mechanism (5), the upper part of which communicates with the outlet nozzle (2) and the lower part with the interior of the package (4), generating a vacuum, negative pressure or positive pressure sufficient to move the product (P) to the outlet nozzle (2), and including an inlet duct (7) and an outlet duct (8), the latter being fitted with an independent and complementary valve mechanism (1) for transforming the flow of the semi-solid product (P) into a drip, trickle or spray.

[0017] As shown in FIG. 2, the independent and complementary valve mechanism (1) is constituted by a tubular cartridge (9) of a diameter and length corresponding to be accommodated inside the outlet duct (8) of the actuator (3), the cartridge having means (10) for receiving the flow of the product (P) to be modified and discharged, in its interior communicating with the inlet duct (7), and correspondingly, inside the cartridge, the moving parts are accommodated longitudinally in the form of jets (11) and respective springs (12), the jets having a rear end supported on the tubular cartridge (9) itself and, at the opposite end, a sealing seat (13) connected to the front end of the cartridge (9) and to the front end of the outlet nozzle (2). In the embodiment, the jet (11) or the obturator tip (13) normally remains pressed against the seal seat (14), and further, the jet (11) or the obturator tip (13) moves away from the seal seat (14) only when the internal pressure in the ducts (7-8) increases, and at the same time, a product flow (P) is also generated in the inlet duct (7) and in the outlet duct (8), so that a drip of the product (P) is discharged into the outlet nozzle (2).

[0018] With reference to Figures 3, 4 and 5, the tubular cartridge (9) presents a frustoconical rear end (15) which facilitates its fitting into the outlet duct (8), which further comprises a closure portion (16) which constitutes a support for the spring (12) therein, and before the frustoconical taper (15), the means of communication (10) with the inlet duct (7) are defined as a series of oblong openings (17).

[0019] The jet (11) has an elongated portion in the form of a cylindrical rod (18) including a plunger-like head (21) with a chamfer (19) at its front end, radial vanes (20) in the middle and a central hole (22) at its rear end for inserting the spring (12), the plunger-like head (21) and the radial vanes (20) having an outer diameter suitable for sliding closely within the tubular cartridge (9).

[0020] The spring (12) consists of a cylindrical pin (23) whose front end is inserted into the central hole (22) of the plunger (21) and whose opposite end has a radial projection bent backwards to form a small leaf spring (24) whose distal end is interconnected with the stabilizer ring (25) to form a support for the closure part (16) of the tubular cartridge (9). Thus, when the pressure in the tubular cartridge (9) increases, the plunger (21) is forced backwards, overcoming the pressure of the leaf spring (24), so that the chamfered end (19) of the jet (11) moves away from the seal seat (14) and allows a reduced amount of product (P) to be dispensed in a drip.

[0021] The seal seat (14) is formed by a rear annulus (26) having an internal chamfer (27) and an outer diameter suitable for penetrating and locking inside the tubular cartridge (9), with a forward flange (28) having the same outer diameter as the tubular cartridge (9) as a penetration limit, which flange is further hollowed out by a central bore (29) having an internal chamfer (30) which constitutes the actual seal seat for the obturator tip (13) of the jet (11).

[0022] In another preferred embodiment shown in figures 6, 7 and 8, structural details are provided that allow the cartridge to dispense a quantity of product substantially greater than a drip, defined herein as a trickle, as occurs, for example, when the product is a lotion. In this case, a larger quantity must generally be dispensed in one operation, so that the sealing seat (14) is modified but maintains a rear annulus (26) with an outer diameter suitable for penetrating and locking inside the tubular cartridge (9), and has as its penetration limit the same front flange (28) with the same outer diameter as the tubular cartridge (9), which is further hollowed out by a central hole (29) in front of which there are two circular widenings: an intermediate widening (31) with a chamfer (32) and a larger rear widening (33), which form two steps (34) and (35) which, together with the central hole (29), form the actual sealing seat for receiving the corresponding end of the jet (11). However, this end of the jet (11) is also modified and terminates in the form of an integral stopper (36) of suitable diameter and length for closing or opening the central hole (29), preceded by a step (37) corresponding to the diameter of the cylindrical rod (18) for closing or opening the intermediate widened portion (31), thereby providing a multi-stage closure and allowing the ejection of a trickle of product, for example in the case of lotion.

[0023] In another preferred embodiment shown in Figures 9 to 12, structural details are provided that enable the cartridge to dispense a metered amount of product in the form of a spray, and for this purpose it comprises a flow-dividing tip (38) and an internal seal seat (39). The flow-dividing tip (38) has a rear annulus (40) of an outer diameter suitable for penetrating and locking into the tubular cartridge (9) and a front blind flange (41) of an outer diameter equal to that of the tubular cartridge (9) as a penetration limit, the rear annulus (40) being fitted with an internal seal seat (39) on its inner diameter, the internal seal seat (39) having a cup-shaped circular part (42) of a corresponding diameter and a rear flange (43) of an outer diameter that fits into the inner diameter of the cartridge (9), and the internal seal (39) is closed at its front part (44) and is fitted with the actual seal seat (39). The front blind flange (41) includes a central bore (45) forming a nozzle hole (18) for receiving the corresponding end of the cylindrical rod (18) of the jet (11) terminating in the form of an integral stopper (46) of suitable diameter and length for closing or opening the central bore (45) and establishing or blocking a single flow reaching the flow dividing tip (38), which is divided into several other smaller flows, so that the inside of the front blind flange (41) is provided with a circular recess constituting a primary distribution chamber (47) between the front blind flange (41) and the sealing seat formed by the central bore (45). The primary distribution chamber (47) has various radial outlets (48) dividing the flow in tangential communication with other secondary distribution chambers (49) of equal circular shape distributed around the circumference of the primary distribution chamber (47), each secondary distribution chamber (49) having in its interior a spiral recess (50) centered on an outlet hole (51) of the product to be sprayed.

[0024] The function of the embodiment shown in Figures 9 to 12 is substantially the same as the previous version, but with a modification to the flow at the outlet of the tip, which is now sufficiently divided and swirled so that product is discharged in a spray at each outlet hole (51), i.e. in the same manner as the previous version, when pressure increases in the inlet duct (7) of the actuator (3), the spring (12) is compressed and the jet (11) moves rearward via the plunger (21), so that the stopper (46) moves away from the hole (45) and an outlet flow of product is established which fills the primary chamber (47) of the flow dividing tip (38). In the primary distribution chamber, the flow is divided into other small flows through the radial outlets (48), each of which enters the corresponding secondary distribution chamber (49) tangentially, at which point the spiral recess (50) induces a swirl of the product flow, i.e. the spiral recess creates a certain effect on the product flow, rotating it with speed and pressure, as a result of which the flow is further divided into jet particles, which are finally discharged in the form of a spray from each outlet hole (51). This functional condition allows the discharge of high-density products such as oils, for example silicones, in the desired form. Logically, when the pressure is reduced and stopped in the inlet duct (7), the whole assembly returns to its original position, whereby the sealing seat (39) is closed watertight again.

[0025] Finally, FIG. 13 shows diagrammatically a simple press-type package, which does not have a pump-type dispenser mechanism, i.e. by pressing the body (C) of the package, an internal pressure can be obtained, which forces the content of the package to flow through a suction tube (P) to a lid or the like (T). In this type of package, the suction tube (P) is provided when the package is handled upright or upright, i.e. it is eliminated when the package is handled tilted or tilted. Unlike the previous embodiment, the lid (T) is not an actuator and does not have a sealing member, so that the flow stops the moment the package body is no longer pressed. The lid (T) is therefore a fixed closure that can finally receive an optional sealing overcap (not shown), in which case the lid (T) includes inlet (7) and outlet (8) ducts communicating with each other, the latter constituting, as already mentioned, a receptacle for the independent complementary valve mechanism (1) of the above-mentioned version and constituting the outlet nozzle (2). In the embodiment illustrated in Figure 1, the outlet duct (8) is shown in a horizontal position, but it is also possible to have it in an oblique or vertical position while maintaining the same functional concept, which does not change the function of the assembly, i.e. by pushing on the body (C) of the packaging, sufficient internal pressure is created to allow the product to flow until it reaches the inside of the independent complementary valve mechanism (1). From this point on, the function of the assembly is exactly the same as described above for all embodiments.
