Description

Technical field

The present invention relates to the creation of a valve with a vertical outlet for activating (driving for the release) and dispensing fluid, which can be connected to the upper part of a hand pump of any type to extract the fluid contained in the container. The specified valve is manually actuated and it is designed to release the proper dose of fluid through the outlet vertically upwards and using only one hand to press the valve down and receive the fluid exiting the upper part of the valve simultaneously and in just one operation, without the need for manipulation with the container, tilting the container or pushing it.

The valve in accordance with the present invention is intended for use with various liquid products: dense, creamy, viscous, emulsified, sticky, oily, jelly-like or foamed, such as aseptic compositions, medicinal compositions, cosmetic compositions, oily or lubricating compositions, cleaning or disinfecting the compositions from which the soap used in the devices for extracting and dispensing, in particular, soap for washing by hand earthenware dishes, glass crockery and kitchen utensils, when it is very important to always have a free hand for secure retention while washing the delicate and sensitive subject, so that this washing flowed continuously and rapidly, with considerable savings in soap, water and time.

BACKGROUND OF THE INVENTION

Most well-known manufacturers of liquid soap use the same system in the container with the "push-pull" valve (4) shown in figure 3, which requires manipulation of the container with both hands. When using valves of this type, whenever the user needs a dose of soap, he must release the plate that he washes from his hands in order to grab the container with his hand, open the valve, turn the container over and press it, while the user holds a rag in his other hand. or a sponge used to wash the plates, on which he applies soap from the outlet of the container, which significantly increases the time of the washing process due to the many interruptions that are necessary to discharge the liquid from the container. In addition, a system with a “push-pull” valve (4) does not allow precise control of the amount of soap used, given that this amount depends on the time the container was held turned down and how much it is pressed, which usually leads to significant loss product and reduces the performance of operations performed using liquid soap for washing dishes.

Thus, if there is no manual pump for extracting liquid soap, having an exhaust system that provides immediate receipt and directing fluid to a rag or sponge, using only one hand and with a dosing system that guarantees a rational and economical flow rate, then use liquid soap for washing dishes will not be convenient or attractive for consumers with low purchasing power, given that the productivity that can be achieved using the already known "two stroke "of the valve (4) is lower than the performance achievable with the use of soap for washing dishes in a foam.

However, due to the high purchasing power of consumers in developed countries and higher environmental requirements in accordance with the strict legislation regarding environmental protection in each such country, the low productivity achievable with liquid soap for washing dishes due to the lack of proper dosing valve is not an obstacle to mass consumption in such countries, which helps to protect the environment and has a beneficial effect on the skin to users in such a degree that annoying and aggressive contaminant dishwashing soap as a foam gradually disappeared from these markets. In addition to the above, it should also be borne in mind that in developed countries, washing of earthenware and kitchen utensils is usually carried out by the same buyers who are directly interested in protecting their hands from the harmful effects of soap.

The opposite happens in developing and underdeveloped countries, where, due to low purchasing power, most consumers involuntarily have to spend most of their money on food and are forced to buy dishwashing detergents that guarantee acceptable performance and good results, regardless of whether that they adversely affect the skin of the hands and are environmental pollutants, and in this case are forced to buy soap for washing dishes in the form of foam, made on the basis of tantalizing and polluting substances. In addition, consumers with high purchasing power in developing and underdeveloped countries do not buy liquid soap for washing dishes due to the fact that they are not direct users, as their maid does homework and it is she who suffers from the harmful effects of soap on her hands washing dishes in the form of foam. Given the above, the main motivation for deciding to buy soap for washing dishes is higher productivity and savings resulting from the use of harmful and polluting soap for washing dishes in the form of foam instead of the proposed liquid soap for washing dishes, which is essentially due to the lack of practical and a proper activation and dispensing valve in containers for such soap.

In this regard, in developing and underdeveloped countries, dishwashing liquid soap is used little because of low productivity, mainly due to the lack of an appropriate container system that allows soap to be dispensed in a dosed, practical and continuous manner, which is often required for a light, practical, quick, safe and economical washing of earthenware and glassware and kitchen utensils, while saving soap, time and water.

These shortcomings are the reason why the use of liquid soap for washing dishes does not grow in developing and underdeveloped countries, which consume thousands of tons of soap for washing dishes in the form of foam based on silicates and carbonates, which is not only an irritating and aggressive substance for the hands users, but also a dangerous pollutant for water resources, and therefore for aquatic life, as well as for groundwater.

In order to facilitate the discharge and improve the dosage of the liquid product contained in the container, and each time to obtain the same amount of produced fluid, other types of hand pumps for liquid recovery have already been proposed. Among these pumps are known piston, bellows, diaphragm, syringe and hose pumps.

In all these manual fluid extraction pumps, fluid enters through the inlet valve of the compression chamber, after which the inlet valve is closed and then the fluid is pushed through the outlet valve into the opening of the activation valve, such as the horizontal outlet valve (3) with a curved handle shown in FIG. .2. These dosing pumps are used for expensive products such as: cosmetic creams, soaps, disinfectant gels, creams and lotions for hands and body, medical creams, essential oils and other viscous products.

In this regard, patent EP 1491123 describes a device that comprises a pump for dispensing lotion or gel with a separate outlet chamber leading to the nozzle, the piston chamber of the pump being insulated at both ends by means of membranes that move with the piston. The upper surface and the cylindrical extension in the upper part of the piston are located inside the piston chamber. However, similar to most existing pumps of this type, the fluid is discharged through a horizontal nozzle, so both hands are needed to manipulate the pump, one of which presses the valve and the other receives fluid or in which they hold a rag or sponge that is directly applied fluid used for washing dishes and other kitchen utensils. Moreover, if the quantity of fluid discharged is greater than required, there is no possibility of retaining the fluid discharged from the metering device. In addition, this type of metering device has problems associated with its high cost and complexity, since it contains a large number of components, which increases the cost of the product put on the market.

Another embodiment of the extraction and dispensing pump is described in DE 197 13 721, which describes a dispensing device releasing measured volumes of liquid or viscous substances, such as soap and body lotions, by means of a piston pump with inlet and outlet valves of the pump chamber, which form seals preventing loss of fluid when the metering device is turned upside down. The pump described in this patent is not simple, taking into account that it contains a large number of components, since it contains a leakage sealing system formed by two valves at the inlet and outlet of the pump chamber, which complicates its manufacture and increases the cost of its manufacture and leads to an increase in the cost of the finished product.

US Pat. No. 4,848,599 discloses a device for discharging liquid from a container using only one hand, which comprises a cover body, a liquid discharge tube, and a mechanism with an air piston pump integrated in the cover. The pump mechanism is connected to the inside of the container, and the piston has a long outlet channel, the free end of which is brought out. Despite the fact that with this device, the extraction of fluid can be done using only one hand, and the other hand remains free, the valve is complex and has a high manufacturing cost, which leads to an increase in the cost of the finished product. In addition, the space intended for the location of the hand is limited and insufficient to receive liquid not on the hand, but, for example, on a rag or sponge for washing dishes and kitchen utensils. Moreover, this device has the disadvantage that residual liquid may drip from the nozzle of the exhaust pipe, and the creamy, viscous and dense liquids held inside the external exhaust channel may dry after several days when the device is not used, blocking the outlet for the liquid contained in the container, and given the large length, narrow clearance and complex shape, it is almost impossible to clean the pump, so you have to throw it away.

US Pat. No. 6736562, which relates to this type of pump, discloses a device for storing and applying liquid to a cleaning device, which comprises a coating module with a sliding cover that can be attached to or integrated into the top of the tank. In addition, the valve described in this patent is not replaceable given the shape of the pump seal. Another disadvantage of this device is the design of this valve, since the receiver for holding the sponge requires the use of both hands, one to hold the receiver and the other to open and close it, which makes it difficult to manipulate it. Moreover, the receiver cover and its wall interfere with quick valve manipulation and fluid extraction. Similarly, due to the complexity and the large number of components, the manufacturing cost is high, which leads to an increase in the cost of the finished product.

In connection with the foregoing, there is a need to create a manual pump for extracting a fluid having an activation and dosing valve that allows fluid extraction in a practical, useful, economical and safe manner and which requires the use of only one hand and does not require manipulation of the container, that the other hand can be used to perform another function that may be necessary to facilitate and accelerate the work being done. Moreover, it is desirable that this activation and dispensing valve be just one part, simple and easy to manufacture, at a low manufacturing cost, so that the finished product has a low price, and which would allow the extraction and dispensing of liquid dishwashing soap continuous, easy in a practical, useful, economical and safe way, directly to a rag or sponge, in order to change the existing practice of using harmful soap for washing dishes in the form of foam, to create a tendency for a significant increase in detoxification of liquid soap for washing dishes, so that users adopt a new liquid soap, which, in itself, does not have a harmful effect on the hands, but rather has a beneficial effect on them during and after washing dishes, because unlike soap for washing dishes in the form of foam, biodegradable ingredients of liquid soap for washing dishes contain substances that are beneficial for humans, which will allow you to change the aforementioned eating habits, and also help protect the environment, as this eliminates the daily discharge of syach tons of pollutants contained in the dishwashing soap as a foam in hydro planet and arable land due to irrigation water produced from subterranean waters.

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to the creation of a valve (1) with a vertical outlet for activating and dispensing the liquid shown in figa and 1B, which is connected to the upper part of any type of hand pump (2) to extract the liquid contained in the container, and which in detail shown in figures 4 and 5, to replace the original activation valve (3), regardless of its shape, for example, such as in the example shown in figure 2, to ensure proper dosage, but with the release of fluid vertically upward.

The valve (1) in accordance with the present invention is intended for use with only one hand, both for pressing down and for receiving fluid, in just one operation, without the need to hold the container. The specified valve (1) is characterized in that it is made in the form of only one part, which contains the upper base (10), which is used as a fulcrum for pressing downward, and also has a concave central surface (11) for holding the remaining liquid and returning them inwardly having an outlet (12) located in its center and separated by a partition (13), which prevents the upper ball used as an outlet valve from falling out and located inside the cylindrical tube (26a), which is part of the manual piston (26) Sosa (2) for the extraction liquid. The valve (1) in accordance with the present invention has a cylindrical tube (14) used for flowing liquid upward, which also contains an external thread (15) in its upper part, which engages with the internal thread (21a) of the manual cap (21) a pump (2) for extracting liquid in order to keep the valve in accordance with the present invention fixed during storage, transportation and demonstration of the packaged product, for example, so that there is no leakage when handling it. Between the base (10) and the cylindrical tube (14), above the thread (15), there are some elements (16) of reinforcement or support, having a triangular shape, which increase the strength and stability of the base (10), whenever it is pressed down . The lower end (17) of such a cylindrical tube (14) is connected with the application of pressure to the outer upper part (26b) of the cylindrical tube, which is part of the piston (26) of the hand pump (2) for extracting liquid.

The valve (1) in accordance with the present invention can be made by molding from various polymers and plastics, such as: polypropylene, high density polyethylene, polycarbonate, etc., or from any other materials that can be used in the molding system similar to any other materials that are used for the manufacture of caps of various previously known hand pumps for liquid recovery. In addition, the valve may be made of materials with metallic properties.

The valve (1) in accordance with the present invention allows the fluid to be extracted whenever the user presses the base (10) down using only one hand, in which, when using liquid soap for washing dishes, he holds a rag or sponge for washing, to directly apply soap to it, while with the other hand he holds the item that he washes. The valve in accordance with the present invention allows you to directly supply fluid to a rag or sponge in the amount that the user considers necessary, in accordance with the need and the number of clicks on the base of the valve.

In the process of washing earthenware and glassware and kitchen utensils, the valve in accordance with the present invention, in addition to saving soap, also saves time and thus water, taking into account that you do not need to let go anymore (set aside) washable item in order to turn over the container containing soap or press on it to remove soap from it, and take the washable item again, so that now both hands are in constant motion and perform the corresponding direct task in the washing process, which It is safe, continuous, convenient and fast.

The valve (1) in accordance with the present invention is also practical and useful for performing some other tasks, such as, for example, body massage, when cream or oil can be removed without the need to hold the container, which saves time and prevents slipping of the slimy container from the hands and can lead to its destruction in the fall and to the loss of the product.

In addition, a hand pump for extracting any kind of fluid to which the valve (1) in accordance with the present invention is connected is also part of the present invention. This type of pump, which is widely used all over the world and is available at a low price due to the high production volume, in particular in China, can be connected to the valve (1) in accordance with the present invention to replace the valve (3) for activating any form when it is necessary to dose the liquid exiting vertically upwards using only one hand, both for activating and for receiving fluid, in just one operation, without the need to hold the container.

In addition to the activation valve (1), the manual fluid extraction pump (2) connected to the container and manually actuated includes a cap (21) having an internal thread (21a) that engages with the valve thread (15) in accordance with the present invention, so that the valve for activating and dispensing the liquid becomes fixed to prevent leakage of liquid during storage, transportation and demonstration of the packaged product. Moreover, the hand pump (2) for extracting liquid has a cap (22), the internal thread (22a) of which engages with the thread of the container on which the specified hand pump is mounted. The mechanical functioning system is formed inside a compression chamber (23) provided with an inlet valve (23a) for the fluid, usually cylindrical and hollow, located in its inner lower part, inside of which the inner small lower ball freely moves between the first position in which the fluid inlet is closed, and a second position in which the fluid inlet is open. In the outer lower part of the compression chamber, the hand pump (2) for extracting liquid also has a cylindrical tube (23b) into which a thin hose (24) is inserted, which goes to the lower surface of the container, from where the liquid flows upward. A piston device (26) is installed inside the compression chamber with sliding, which has a passage for moving fluid from the compression chamber (23) to the outlet of the activation valve, before it was passed through a cylindrical tube (26a), which is part of the same piston and in which the inner small upper ball, which serves as an outlet valve, freely moves between the first position in which the fluid outlet is open and the second position in which the fluid outlet is closed. The outer upper end (26b) of the piston cylinder (26a) (26) is connected by applying pressure to the lower part (17) of the cylindrical tube (14) of the valve (1) in accordance with the present invention, whereby the fluid inside is supplied outward at each actuating the valve. The compression chamber (23) also has an elastic device (25), which is installed in the inlet valve (23a) and serves to move the piston to its upper part, after it has been compressed by pressing the activation valve.

The manual pump (2) for extracting fluid works as follows: when the user presses the activation valve (1) down, he presses the piston (26), which sets the upper ball in its first position to release the fluid outlet, while the piston compresses the elastic device (25) and moves upward the dose of liquid that will be inside the compression chamber (23), allowing it to exit through its own passage into the upper part of the valve (1) in accordance with the present invention, since due to the same pressure, provided by the piston (26), the ball in the inlet valve (23a) will be located in its first position to close the fluid inlet, which does not allow the liquid to return to the container, but, on the contrary, causes it to go up. When the user releases the activation valve (1), the elastic device (25) pushes the piston (26) up, setting the upper ball in its second position to close the fluid outlet, creating an empty space in the compression chamber, which can again be filled with liquid, since the ball in the inlet valve (23a) is in its second position to allow the receipt of a new dose of fluid, which will be inside the compression chamber (23) for the next activation, and so on, at the request of the user.
