Description

CONCENTRATE RELEASE COVER FIELD OF THE INVENTION.

The present invention relates to a closure or dosing lid, more particularly to a concentrate release lid inside a beverage container to add the concentrate that can be a flavoring, vitamin, medicinal or other.

BACKGROUND OF THE INVENTION.

The field of application is the market of flavored drinks, energy, food supplements, vitamins, naturopathic, medicinal, chemical or others, which once mixed with the liquid shelf life is significantly reduced, so once mixed should be consumed or used in a short term.

The product or concentrate to be mixed, which can be powder, granules or liquid retained in the cavity or tightness of the lid, are used to close the bottles that have already been previously filled with the liquid in the bottling lines, leaving the bottle with its lid ready to be sent to the market, pending a labeling operation of the bottle and / or a secondary packaging.

You can do the filling of the lids previously in an attached line of filling caps, inside the bottling plant, and feed these lids with product to the bottling lines or fill them in an independent plant and send them to the bottling plant for its application in the bottling line.

The caps once filled with the product are placed in the bottles' beak by means of a closing machine that is part of the bottling line, once the bottles have been filled with water or another liquid for human consumption during the bottling process , having this the finished product to be sent to the market.

Once the finished bottle is in the hands of the end user, this will trigger the mechanism to release the product, which will mix with the liquid, then shake and once mixed will proceed to open the bottle, with the turn of the lid to break the safety band, which may not be in the body of the lid, in this way the mixture of the liquid with the product is ready to be consumed.

In the state of the art there are some covers that have some drawbacks in relation to the lid of the present invention, as is the case of the lid lacto tab, which is a lid used in the product "Lacto Tab" of the company EMMI, from Switzerland, which consists of 5 pieces of plastic and a bottle with special collar, the cap consists of a capsule formed with two sheets of aluminum, in this capsule the product is contained either in powder or liquid, which can be a flavoring , vitamin or energetic, this capsule is placed on the neck of the bottle and is adhered by means of an induction process, then it is installed the lid that is of special dimensions and shape, according to the neck of the bottle, the operation of which is the following: The lid is turned in a clockwise direction, with this rotation the safety band is broken and continuing the rotation an inner rod moves down, the rod at its lower end has teeth or points that with the turning movement and the vertical downward movement, tears the aluminum capsule, allowing the product to spill into the liquid contained inside the bottle, where the product is mixed with the liquid by means of agitation of the container, thus obtaining the mixture of the product With the liquid and the drink is ready to take it, the lid in its upper part has a protective cover, which is removed and the seal is pulled that will allow the exit of the liquid already mixed, this last concept being used in caps of the type known as "sport cap" or sports, "push-pull" push and pull, as pushing the seal back down again closes the output product duct.

This lid was only used in this product and left the market for not being successful, its cost being very high, since it consists of five pieces, the aluminum capsule, which must be filled with the product previously and assembly of the cap and a special neck on the bottle, also requires a special capper or engargoladora to install the aluminum capsule and then the lid, all this increases the cost of the product.

Another cover in the state of the art, is the one-piece dispensing lid, consists of a cylindrical section for storage of the product, which is sealed with an aluminum film, which closes the storage section of the product, the lid in its internal part has a semicircular section, whose diameter rests on the wall of the storage section, in the center has a stem that at the lower end has a series of tips, this part is inside the storage section.

The lid works in the following way; the concentrated powder or liquid product is placed in the storage section, sealed with the aluminum film, ready to be installed, in the filling line the lid is installed in the bottles with standard neck of the market.

Once the bottle is in the hands of the consumer, it proceeds to push down the semicircular part that is in the center of the lid on the top of the bottle, with this action, moves down a stem and with the tips located at its lower end, breaks the aluminum seal, and allows the passage of the product to the liquid with which it is mixed by agitation of the bottle by the consumer, once the product has been mixed with the liquid, is removed the lid, in the same way that the standard caps are removed, breaking the guarantee band and leaving the product ready to be consumed.

Sometimes the rupture or tearing of the aluminum is not large enough to allow the complete exit of the product, resulting in a mixture poor, since the stroke of the shank is limited by the semicircle, the cost of the injection mold is very high, since the shape of the tips on the shank are complex requiring injection molds of plastic with complex mechanisms that make the cost of the piece very high. Also on occasions the semicircular sector where the pressure was applied to break the aluminum, returns to its original position, without having torn enough the aluminum seal, resulting in a poor mixture of liquid with product.

The patent application of the United States of America US2010 / 0044254 published on February 25, 2010 whose inventor is Joseph Romeo, describes a lid for beverage container that supplies a flavoring material within the liquid contained in the bottle, includes a top element adapted and built to maintain a predetermined amount of flavoring. A central element is connected to the upper element by means of a valve mechanism which is activated so that selectively the flavoring is contained within the container, the valve is activated by means of the rotation of the central element with respect to the base. Said lid consists of several pieces and is of complicated construction.

The Korean application KR20070060132 published on June 12, 2007 whose inventor is Yorita Katsuhiko, describes a lid in which powder tea is placed to mix with the water contained in the container. The lid is built to be removed by means of a screw thread from the bottle's beak, it has a lid at the top that is opened by means of rotation and also a part that is pressed on the top of the bottle. vertical direction in combination with the turning movement. In the lower part of the cap that is pressed provides a cylindrical container that receives a flavoring mixture and that breaks mechanically in the bottom of said container, a pressure bar is formed integrally with the lower surface and projects towards above. To spill the flavoring the top cover is rotated and pressed downwards this opens and breaks the weakened section of the container and allows mixing with the contained water.

The patent application of the United States of America US2007 / 0102306 published on May 10, 2007 whose inventor is Emery J. Lantos et al. Discloses a bottle cap that includes a base member a sliding upper member coupled to the base, the member superior has a dispensing member. A sliding crown member engages with the upper member and then the base member and the upper member form at least one flavor tank which is released by removing the safety band and forcing the downward rotation.

The international application WO2006 / 123946 published on November 23, 2006 describes a cover for a container that includes a chamber that stores a flavoring substance separated by means of a flexible membrane, the membrane opening device includes a central support structure in the shape of a cylinder that has cutting teeth in the lower base, said cylinder acts by means of pressure that is exerted on the upper face of the cap formed by a flexible cap which suppresses with the thumb, when pressed the teeth break the membrane or seal and release the flavor to mix with the water or drink contained in the bottle; but most of the time the teeth do not completely break the membrane and the flavor remains trapped inside the container.

The Mexican patent application MXPA06002700 and corresponding to the US7,475,774, published September 4, 2006 discloses a lid for a beverage container said lid is provided with a compartment containing a flavoring substance, said cylindrical side compartment with an upper wall and a fragile bottom wall, provided with a blade cutting that moves in relation to the side wall and the bottom wall in order to open the lower wall and release a flavoring substance inside the container or bottle. Again this lid works by means of pressure from the upper compartment that forces the base to interact with the blade that breaks it and allows the release of the flavoring.

The United States of America patent US6,372,270 published April 16, 2002 and whose Inventor is Sean P. Denny, describes a screw cap containing two portions and one of them defines a chamber containing a drinkable mixture, as for example tea bags, etc., a seal is provided to prevent the mixing of the beverage and the water inside the bottle only until it is desired. It has an impeller that pushes down and forces the flavor to break the seal and spill the flavor in the water contained in the bottle.

United States of America patent US4,722,449, published on February 2, 1988, whose inventor is Warner F. Dubach, which describes a container lid with a thread on the bottle's beak and provided with a safety band, in this case the seal is a film that can be easily broken, then to release the flavoring content the safety band should be removed and the lid turned down so that a spiked element will pierce the seal and release the flavoring material into the liquid content in the bottle; but this lid has the risk that in the placement of the same at the peak of the bottle the pressure is exceeded and the seal is broken releasing the flavor at an unwanted time, it is also a lid provided with a complicated structure that makes a manufacturing process too expensive.

The Mexican patent application MXPA2006005798 published on November 22, 2004 and whose inventor is Jung Min Lee discloses a cap containing a flavor with a hollow main body and a support tube extending downstream from an interior surface of the hollow main body the support tube has a discharge portion and a seal element formed at the lower end thereof, the movable member coupled to a fixing element. The open lower end of the tube is sealingly coupled with the seal element, to discharge the concentrate the tube is lifted and the concentrate contained therein is discharged into the liquid contained in the bottle; but again it is a too complicated system that must be turned move up and manufacture two threaded bodies that surely results in too expensive production.

The Mexican patent MX261034 granted on October 10, 2008 for The Procter & Gamble Company describes a system for incorporating minerals in bottled potable liquids, the system consists of a lid provided by a powder tank and an opener that adapts to said lid provided with an arrow shaped stem that breaks the seal of the lid and The contents are released into the liquid in the container.

DETAILED DESCRIPTION OF THE INVENTION There is a condition that some beverages have a short shelf life once prepared, requiring special storage or refrigeration conditions, or even the restriction of being consumed in a short period, since if this does not happen, they lose their properties for those that were prepared, reducing its presence in the market, these drinks can be a flavoring, a vitamin, an energizer, a food supplement, a medicinal product or others.

Sometimes to extend the shelf life, the use of additives is necessary, preservatives or other substances in the product, which increases its cost and modify its properties, in other cases, also change the bottles where the product is packaged, through the use of UV protectors, pigments or other additives that help to prolong the shelf life of the product. The above causes an increase in product costs in the distribution, change in the properties of the beverage and in most cases the shelf life required is not reached, with the consequent impact on the marketing of the product.

The concentrate release lid of the present invention is designed to prolong the shelf life of the product, keeping the concentrated flavor or other product separate from the liquid until the moment of consumption and thus the required shelf life is maintained and maintained. the properties of the product with the special characteristics of the beverage.

The concentrate release lid is designed to keep the concentrated product separated from the liquid used as the mixing agent, which is contained in a bottle, said bottle can be made of glass or plastic or other material, being a bottle with the standard characteristics of the bottle. market, thereby allowing the product properties to be maintained for a long period on the shelf, mixing the concentrated product with the liquid until the moment of consumption, thereby reducing or eliminating the use of additives, presenters, or other substances in the product. product and avoiding the use in bottles of protections of UV rays, even of pigments that increase the cost of the product and do not extend the shelf life for such prolonged periods, with the use of the lid of concentrate release if they can be reached for long periods of shelf life and maintain the original properties of the product.

The lid is manufactured by means of the plastic injection process, using a resin such as polyethylene or polypropylene, plastic resins commonly used to make these parts, it is designed so that when it is extracted from the mold, in the extreme part of the lower edge of the cylindrical body, there is an inclined or chamfered section pointing inside the cylinder, which functions as a pressure element or as a contact area and coupling with the seal. this part during the filling process will be pushed towards the inner face of the cylinder, remaining with an angle that ensures an area of total contact with the seal. The angle ß that has the area of seal in the cover and that is formed with the cylindrical wall of the same is greater than the angle a of the perimeter wall of the seal, with this ensures total contact of the seal with the lid (ß > a) at the time of assembly due to the ratio of the angles that at the moment of the coupling these angles are equalized to provide a hermetic seal between both pieces. Once the seal has been assembled on the cylindrical sealing edge of the lid, the angle ß is forced to equal the angle a, leaving a tight contact area, pressing together both surfaces of the seal and flange of the cylinder wall, ensuring the Hermetic seal between both parties.

The seal also has a perimeter ring "a" that serves to ensure that the seal is uniformly seated on the edge of the outer diameter of cylinder "c", additionally the seal at the lower edge of the sloping contact wall has a slight projection V to retain the edge of the contact tab "d" of the lid in its correct position to achieve the hermetic seal.

The design of the seal is symmetrical with a rhombic shape, which allows its installation on any of its two sides to be equal to each other.

The seal is fixed to the lid in the center of the lid, where there is a cavity with a groove and an intermediate perimetral eyebrow, which when opened allows the passage of the cap stem, whose conical shape facilitates the orientation of the seal with the shank, said shank has a diametral groove that allows it to reduce the diameter or thickness to facilitate the insertion in the seal, once the shank penetrates the seal, the parts are recovered to their original shape and the seal is firmly attached to the stem and in the area of the seal, the contact between the seal and the lid is made uniformly and with pressure, ensuring its airtightness.

Filling of the lid, this operation is carried out in a filling machine in which, by using an orienter, the lid is placed in the inverted position, with the mouth facing upwards, the lid passes through a station in which the section that is where the ring will seat is folded towards the inside of the cylinder, this part of the lid is molded at an angle that allows the lid to be removed of the plastic injection mold, then it is filled with a dispenser and closed, inserting the seal on the stem of the lid, leaving the outer diameter of the seal on the diameter of the cylinder and the seal areas in contact, ensuring the tightness in the cylinder with the seal.

This lid has as main features, which stores the product hermetically, its release is done by pressing the center of the upper part of the lid with the finger, until by the spring effect and recovery of the plastic, said upper central part of the lid it is kept in an extended position downwards, pushing the body of the seal to allow the opening of the same and the exit of the content inside the tightness of the lid and allowing its passage towards the liquid, then the consumer proceeds to shake the container until achieving the mixture between the product and the liquid of the drink, open the lid as is normally done with standard lids and consume the mixture made.

Figure 1 is a top view of the round lid (1) of the present invention wherein each of the circumferences defining the different zones and relevant elements thereof is shown; the circumference of greater diameter shows the edge of the skirt (4) that limits an upper flat ring (2) defined between the diameter (4) and the internal diameter (5) that delimits a central cylindrical body that extends downwards in and up beyond the lower limit of the skirt; the diameter (5) limits a flexible center (3) defined by bending surfaces and a central ring to form a flexible bellows type spring; the next diameter marked on the external fold (6), followed by the internal fold (7) of the flexible center, the fold (7) is the outer limit of a flexible central flat ring (8) that is concentric with the minimum internal diameter ( 9) of the circumference that defines a central stem that extends down until it exceeds the edge of the cylindrical central body boundary. One of the novelties of the lid of the present invention is the flexible bellows-like center that, when pressed, pushes the central stem and even beyond the boundary of the cylindrical central body. The flexible central ring is at a lower level in relation to the upper ring of the skirt, said pressed ring is depressed up to the level of the first thread.

Figure 2 is a bottom view of the round lid (1), showing the flexible central ring (8), the central stem (21), the central cylindrical body (5) and its thickness, the outer skirt (2). 4) and the seal area of the lid (20). The central stem (21) has a diametral groove (22) that allows it to have a pin with flexible coupling diameter, said rod in a diameter defined by a central circumference (9) concentric with the ring (8) limited by a circumference of the fold (7), in the direction towards the largest diameters is the circumference that defines the fold (6) and then the thickness of the cylindrical body (5) that defines the walls of the tobacconist where the flavoring concentrate contained in the lid is stored together with the seal, to be released at its proper time prior to the consumption of the beverage contained in the bottle; between the cylindrical central body (5) and the external skirt (4) of thickness (20), an empty space is defined where the peak of the bottle enters with its own thread on top of the neck.

Figure 3 shows a side section view of the lid (1) of the present invention, the skirt (4) and the internal threads (30). Said skirt attached to a security band (34); the cylindrical central body (5) defining the tobacconist containing the concentrate and holding at the upper end to the central ring (8) and the folds (6 and 7) of the flexible center (3), it is to be noted that said flexible center it is at a lower level with respect to the level of the upper ring (2) of the skirt, said flexible center (3) of the folds (6 and 7) and the central ring (8) having attached on the inner side a central stem (21), said rod has at the lower end a coupling pin (31) of smaller diameter and with a diametral groove (22) that makes said pin flexible (31), the rod can be moved downwards thanks to the folds ( 6 and 7) when pressing the flexible center (3) in vertical direction. The central cylindrical body (5) extends beyond the limits of the safety band, at the lower edge (c) it has a flexible flange (d) in inward fold that functions as the contact surface and coupling of a barrel-like round body with sloping walls that serves as a seal to contain within the cylindrical body the flavoring, medicinal, energizing, vitaminic, or other concentrate containing the lid of the present invention.

Figure 4 is a top or bottom view (50) of the seal of the present invention, in which the perimeter ring (a) which functions as a coupling packing or stop surface for the edge of the central cylindrical body and is shown located on the vertical flat surface of the seal body; after the surfaces inclined towards the central diameters which have two outer perimeter rings (b), a vertex is formed and another surface is extended inclined upwards and towards the center ending up to a horizontal support or disk (53) to form the diameter ( 59), the disc (53) provides structural support for the seal and the central cylindrical structure (54) defining the entrance of the shank of the central stem of the lid, said inlet (55) being flanked by an inclined perimeter eyebrow (56) which works as a stop for retaining the spike. This central structure (54) has a groove (42) that gives it flexibility and can be opened when coupling the pin to save the stop (56), the same pin also has a central groove that allows it to reduce the diameter to be coupled To the seal by means of a click, once inside the spike the stops complement each other by matching horizontal surfaces that prevent the decoupling between the seal and the spike.

Figure 5 is a side sectional view of the structure of the seal (50) that has the shape of a barrel, with a perimeter ring (52) of rhombic shape joined by a support horizontal (53) intermediate or disc, which in turn has a vertical central support (54) of vertical wall divided into an upper and lower section, whose interior defines the entrance (55) of the spike, the interior of the vertical support ( 54) has an inclined wall eyebrow (56) which functions as a stop for the coupling pin in cooperation with the eyebrow thereof; the rhombic perimeter ring (52) and the horizontal support (53), the vertical support (54) defines the internal spaces (57) that make the seal a light and resistant piece due to the structural arrangement described. The external lateral curves of the rhombic perimeter ring (52) have rings that act as a contact surface in the flexible flange of the end of the cylindrical central body, the upper and lower contact surface (58) has the perimeter ring (b) and the The intermediate surface or abutment surface (51) has the circumferential ring (a) adhered to it and functions as a stop with the lower end of the central cylindrical body that defines the tobacconist that contains the concentrated substance.

Figure 6 is a side cut-away view (60) of lid and seal coupled in the closed position (61) of the seal (50) coupled to the stem (21) and to the internal eyebrow of the end of the cylindrical body (5), the coupling between the rod (21) and the seal (50) is carried out through the pin (31) and the contact surface of the rhombic perimeter ring (52); the lid also has the skirt (4) which is a coupling element to the bottle peak through the threads (30) and the safety band (34) which is an indicator of opening violation of the bottle. In this figure the seal is in the closed position with the folds at position (61) that are retracted and keep the stem (21) at the highest level.

Figure 7 is a side section view (70) of the semi-open seal that generates a partial opening (72) and that allows the concentrate to be stored inside the cylindrical body. In this position the depressed flexible center (71) is not deployed to its full extent, this causes the central stem (21) to uncouple the seal of the perimeter eyebrow (d) located at the end of the cylindrical body; the seal has a ring-shaped contact surface of rhombic perimeter shape (52) symmetrical with respect to a horizontal plane and with respect to a central axis. The rhombic perimeter ring (52) has an internal structure composed of a horizontal disc and a central hollow cylinder that defines a coupling opening with the shank of the central stem, the structure of the ring allows it to be coupled on both upper or lower sides for facilitate the assembly of the complete cover with the seal.

Figure 8 is a side section view (80) of the completely open seal that generates a maximum perimeter opening (82) since the central stem (21) is completely displaced because the flexible center is depressed to its maximum reach (81) that matches the lower edge of the first thread. This position generates a maximum perimeter opening (82) because the perimeter contact ring (52) is completely separated from the perimeter eyebrow of the cylindrical body. In this way it is avoided that remains of concentrated substance remain inside the cylindrical body of the lid, because for a homogeneous mixture the bottle is agitated and through the opening (82) the liquid passes through of the same and even rinses the walls of the concentrate container, which does not happen in the covers of the state of the art.

Figure 9 is a side view of the seal of the present invention, showing the external surface (90) thereof in the form of a barrel, composed of two rings with smooth inclined surface and a central ring with vertical smooth surface; the inclined surfaces (58) are of contact and still on the edge of each one of them has a ring of flexible material (b) that makes the packing function for the coupling with the internal eyebrow of the cylindrical body of the lid and of this way you have an airtight seal that prevents unintentional withdrawal of the concentrate. The intermediate vertical ring (51) also has a covering (a) that serves as a stop with the edge of the inclined eyebrow of the cylindrical body and that does not allow the seal to go further inside the cylindrical body and that at a certain moment it can be opened more of due the cylindrical body and also to break the flexible center of the upper face of the lid. In this figure it is shown that the contact surfaces 58 are symmetrical with respect to the central abutment surface 51 and with this it is easy to find the appropriate coupling face when assembling with the cover.

Figure 10 is a side view of the lid with the skirt (4) and the violation seal (34) and the end of the cylindrical body (5). The skirt (4) has a textured vertical lines (101) that function as a grip surface to rotate the lid (100). The seal of figure 9 and the lid of figure 10 form the dosing lid of the present invention, for its coupling the lid is placed in a support with the cylindrical body open upwards and the seal, inside the cylindrical body is filled with concentrate and then the seal is pressed into the rim and inside the cylindrical body.

Figure 11 shows a cross-sectional view of the coupling of the seal with the stem of the central stem (21). The internal structure of the seal forms a pair of upper and lower housings with an intermediate ring formed by the abutment stop (56) which retains the stop flange (112) of the peg (31), which can pass through the ring due to the central groove (22) and the groove of the seal (42), which open or close due to the pressure exerted. Then the central stem (21) in an upright position and presenting the coupling pin (31) with its side walls inclined on said pin the pressure seal is placed and the pin (31) occupies any of the upper housings (113) or lower, as the case may be for the same formed by the vertical walls (54) that emerge from the horizontal disc (53). The vertical walls (54) have a projection with perimetral inclined walls forming the abutment edge (56) that define the entrance (55) of the coupling pin (31), it also has a vertical slot (42) that allows the walls (54) open under pressure and allow entry of the coupling pin (31) which is trapped within the stop eye (56), thus between the tab (112) of the pin and the eyebrow (56) within the vertical walls (54) a stop is formed that prevents the deliberate movement of both parts. The coupling pin (31) also has a central groove (22) that under pressure it allows reducing the diameter and consequently of the stop tab (112) to be able to be located inside the housing (113).

Figure 12 is an enlarged sectional view of the coupling (120) between the seal and the cylindrical body (5) in which the surfaces of the rhombic perimeter ring (52) are coupled with the eyebrow (d) of the cylindrical body (5). ) and in which the ring (b) of the edge serves as a stop complementary to said eyebrow, so also the ring (a) functions as a stop complementary to the edge (c) of the cylindrical body of the lid. In this coupling the angle between the wall of the cylindrical body and the eyebrow (d) is greater than the angle between the vertical wall and the inclined wall of the rhombic perimeter ring (52), this generates a tight and hermetic coupling between both parts that prevents the unintentional release of the concentrated substance stored within the walls of the cylindrical body (5) of the lid or reservoir thereof.

Figure 13 shows a sectional view of the two parts of figure 12 separated in which the angle (130) and the angle (131) are shown with a relation in which (131) is greater than (130); the angle (130) formed by the contact surface of the rhombic perimeter ring (52) and with the vertical wall thereof; the angle (131) formed between the cylindrical body (5) and the eyebrow (d) and having as its vertex the edge (c) at said end engages the perimeter ring (a) of the seal. In the coupling of both parts a = ß or (30) = (131) with which a hermetic tight coupling type female-male is achieved.

Figure 14, the two components of figure 13 are coupled and the pressure exerted by the rhombic perimeter ring (52) on the eyebrow (d) forces the the opening thereof is equal to that which is the same there is only one angle (130) between the internal wall of the cylindrical body (5) and the contact surface of the rhombic perimeter ring (52), the edge (c) is located in the position in which the perimeter ring (a) of the seal is placed in contact with it, in this way the hermetic coupling between the cover and the seal is present, protecting the concentrate inside the cylindrical body of the cover and the seal attached to the same to form a hermetic seal, controlled by the flexible center of the lid.

Figure 15 shows a cross-sectional view of the lid with the seal engaged in its position of use and between them contains the concentrate (151). In this figure the flexible center is in the retracted or closed position (61), the seal (90) in position coupled to the end of the cylindrical body (5) of the sealed lid (150) which in turn is composed of the side skirt (4) and the safety strip or strap (34) which is essential. If it is desired to release the seal (90) from the closing position it is necessary to press the flexible center of the lid vertically downward to release the concentrate (151) stored therein.

Figure 16 shows a sectional view in which the flexible center of the lid has been pressed down to an open position (81) that causes the release of the concentrate (151) since the seal (90) is uncoupled from the rim of the cylindrical body (5) of the lid, as a result of which the rod (21) has driven it to leave its closed position. Once the concentrate has been released (151) the bottle is shaken to achieve a homogenous mixture of the beverage to consume it. The lid is still attached to the bottle through the threads in the inner face of the skirt (4) and safety band (34) has not been violated, the mixing operation can be carried out without opening the lid.

Figure 17 is a side view (170) of the lid with seal in closed position in which the skirt (4) is shown with the textured vertical lines followed by the safety band (34), the section of the cylindrical body (5) with the seal (90) located on the lower edge of the cylindrical body (5). In this position the seal (90) is engaged, that is, in the closed position and only shows the stop surface and the lower contact surface, since the other contact surface is inside the skirt wall.

Figure 18 is a side sectional view of a metering cover of the state of the art with a central flexible dome that drives a cylindrical body (184) with teeth (185) at its lower end; the side skirt (181) forms the deposit (182) of the concentrate separated from the bottle peak by means of the metal or plastic film forming the seal (186); pressing the flexible dome (183) drives the cylindrical body (184) and the teeth (185) break the seal (186) releasing the concentrate, but in most cases the seal resists and only allows small holes in the case of a powder concentrate is not 100% released, and in some other times the seal does not even break due to insufficient pressure, lack of sharpness in the teeth, or that the pressing operation was too fast without depth and the seal is intact.

Figure 19 is a side sectional view of another dosing lid of the state of the art which consists of a lid with two compartments for concentrate (191) and (192), both provided with a release mechanism by means of a lever that is activated by means of the rotation of the lid. In this case the cover is too complicated, contains loose pieces that must be assembled and therefore raises its production cost. Although the lid in this case works efficiently its production is too high and inappropriate to survive in the market. The lid consists of a skirt (190), a base (195), two release levers (194) that retain a content (191) and (192) inside the tanks (193) located inside the skirt (190), The top is secured to the bottle peak by means of the cylindrical body (195).
