DISPENSER CAP FOR LIQUID CONTAINERS

TECHNICAL FIELD

The present invention falls within the field of devices that are used as lids or plugs for liquid containers, such as water.

Thus, the present invention relates to a push-pull type lid for dispensing liquid from a container which is installed or located in the mouth or access opening of a container. Said cover is composed of two parts that correspond to a push and pull type section and a central fixed body, where these two elements interact with each other and are located one above the other to allow the cover to be installed properly and successfully in different containers, both pressure and thread type and of different diameters. In this way, the lid of the present invention is located in the upper part or opening of the liquid container, and works in such a way that when the lid is pulled it opens to allow the dispensing of the fluid from the container and when it is pushed it closes hermetically, allowing the push and pull mechanism. Likewise, the push and pull part has a tab or security seal that, when pulled for the first time with respect to the central fixed body and the lid, breaks the security seal of the lid and the central fixed body, leaving evidence of its first use.

BACKGROUND OF THE INVENTION

Currently, the use of liquid containers or containers allows access to an essential fluid, such as water, in remote locations where it is possible to have said resource through an aqueduct or similar. Therefore, these containers usually have a fairly large capacity to allow it to be refilled and not become a disposable and single-use item. However, when you have these large containers or containers, dispensing the liquid can be difficult because these containers have an access opening that has a large diameter, compared to personal size containers. Therefore, it is required to have a lid or an element located in the access mouth that allows both the product to be dispensed when required, but also allows the product to be closed or sealed when it is not in use.

In accordance with the above, it is required that the lid or plug that is located in the access mouth of the container be in turn a valve, that is, it allows the liquid to be dispensed while allowing the entry of air so that it does not leak. Create a vacuum effect inside the container and there can be a constant flow when the valve opens and the liquid comes out and is delivered to the end user.

Thus, in the state of the art, several types of devices or apparatus are known that serve as a dispensing lid for containers or liquid containers, among which are the following, which are included in the present disclosure as a guide. reference only.

As a first measure, document W02005087602 discloses a one-piece plastic lid that is used with a liquid container that has a neck that extends to an open mouth, the lid has an annular base and an outer skirt portion that extends upward from an outer periphery of the base. The outer skirt portion and the base are adapted to fit tightly over the neck and mouth of the container. A tubular portion defines a central opening in the base and extends from the base upward to a top end. The tubular portion includes an inclined cap that covers the upper end thereof. The cap is connected to the tubular portion by a cap tear line that extends around the outer perimeter of the cap. A pattern of ribs extends along a central portion of the cap, adding strength and improving the uniform flow of the plastic when the cap is formed. Cap tear line It is interrupted at the uppermost part of the cap by a portion of improved wall thickness that forms a hinge between the cap and the tubular portion when the tear line of the cap is separated from the tubular portion.

Now, international publication W02008104854 discloses a dispensing closure for a liquid container that is arranged to be sealed to an opening of the container. The closure comprises at least one storage compartment formed integrally with the closure and arranged to store a substance. Each storage compartment has a dephmible top and is arranged so that pressing the top of a storage compartment facilitates the release of the respective substance into the container. The dispensing closure further comprises a dispenser that protrudes through the closure. The dispenser includes a dispensing cap movable between a closed and an open configuration, so that, in an open configuration, the liquid contained in the container can be dispensed therefrom.

On the other hand, there is document WO2016059428 related to a dispenser comprising: a) a reclosable opening in, or for mounting in and/or around an opening of a container having a cavity to receive at least a unit of a product to be distributed; b) a controller adapted to control the opening of the resealable aperture; c) a receiver adapted to receive a user authentication signal; d) a power source to power the controller and receiver; and wherein the dispenser only allows opening of the reclosable opening when the receiver receives an authentication signal from the user. The invention also relates to a distribution system, a distribution method and a set of parts that includes said distributor. The inventions are particularly suitable for dispensing pharmaceutical products only to the intended recipient and also for ensuring compliance with dosing regimens. Likewise, document US10099827 teaches a dual-function dispensing lid that has an inner lid and a rotating outer lid on the inner lid, first and second liquid dispensers on the inner lid, first and second access holes in the outer lid, the access holes being in overlapping alignment with respective ones of the liquid dispensers in an open position of the outer cover, and wherein rotation of the outer cover to a closed position moves the access holes out of the overlapping alignment; first and second covers hinged to the outer cover to open and close individually raised to cover the first and second access holes respectively in a closed state of the covers. Conduit segments in each lid telescope to form ducts that bridge the space inside the lid. The plugs and caps on the outer lid act as plugs that close the liquid dispensers in both the open and closed positions of the dispensing lid.

Now, document FR2982849 also discloses a cap, intended in particular to close the neck of a bottle, which comprises a neck closing cap and a skirt for fixing to the neck, this skirt being provided with a protuberance line to interfere wedged with the neck, a line of weakness to be broken by the propagation of a tear, and a tear arresting means to prevent the tear from extending into the rectilinear extension of a first part of the line of tear, weakness, which It runs along the line of protuberance, being located on the side of the latter opposite to the operculum. To improve the ease of release of the cap with respect to the neck, the weakening line further includes a second and third substantially straight parts that, following the periphery of the skirt, respectively succeed the first and second part of the weakening, line, whose second part of the weakening line avoids the stop means and extends on both sides of the line of the protuberance, being inclined both with respect to this line of the protuberance and with respect to the direction of the axis of the skirt, and whose third of the line of weakness extends along of the line of protuberance and is located on the side of this line of protuberance that faces the operculum.

Similarly, document FR2985718 describes a bottle neck cap comprising a neck closing cap and a skirt for fixing to the neck, this skirt comprising a first skirt part, provided with a protuberance line to interfere with the wedge. neck, and a second skirt portion, adapted to substantially tightly surround the outer face of the neck. To avoid the presence of liquid between the outside of the neck and the inside of the skirt after placing the plug, the inner face of the second part of the skirt is provided with drainage means, in particular rib projections, adapted to delimit flow passages of fluid between the second skirt portion and the neck, which connect the opposite axial ends of the second skirt portion to each other.

Finally, there is document CN101234688 which refers to a disposable anti-theft drinking container, which comprises a container body, a container neck and a container lid, characterized in that the container neck is provided with a pull cap and a locking strap; a bucket belt is provided with an anti-theft center piece; a lower end of the hub cover is provided with an anti-theft ring; An opening in the neck of the hub is provided with a sealing aluminum foil. The pull plug, locking strap and bucket body are connected as a whole and are injection molded in one go; The anti-theft center piece on the hub cap, the anti-theft ring at the bottom end of the hub cap and the hub cap are connected as a whole and are molded by single injection. The disposable anti-theft drinking container establishes a plurality of disposable anti-theft markings that indicate that the drinking container is used and that the drinking container cannot be reused if any component is removed or damaged, thus ensuring disposableness. The drinking fountain of the invention is disposable, thus guaranteeing clean and hygienic drinking water, completely solving the problems of recovery, transportation, sterilization, washing, etc., of used bottles, and saving time, effort and cost.

Now, at the national level in Colombia there is also a series of disclosures related to dispensing lids for containers, among which is document CO01075861 that teaches a lid for a drinking water bottle characterized by having a built-in dispensing valve that has adaptable dimensions. to the capping lines in the bottling systems currently used, where said cap has a breathing system that, by channeling, separates the incoming air flow from the outgoing flow, avoiding flow turbulence. In addition, the dispensing valve cover is characterized by the simple operation of a plunger that is pulled manually to open the passage of water, and presents a flexible material packaging that ensures airtightness in the assembly to the drinking water bottle.

Additionally, document CO10135974 discloses a liquid dispensing valve made up of: a) a cover that has in the central internal part a tube perpendicular to the upper surface, with a closed base which has two small stops towards the outside and the other end, is a central circular hole towards the upper surface; The tube in its wall has a hole towards the top, and on the opposite side a small hole; and inside the tube there is a vertical rectangular wall and a semicircular wall attached to the wall; b) a lid having in the central internal part a tube perpendicular to the upper surface, having a central circular hole towards the upper surface of the lid and the lower end is closed, with two semicircular perforations; The tube in its wall has a circular hole towards the top and a small hole towards the opposite side; c) a lobed-shaped cover which has a small hole and a small stop towards the bottom; and d) a circular gasket or washer on the inner wall of the valve cover.

From the above information, an expert in the field can clearly determine that in the state of the art there is a series of devices that correspond to lids or plugs that are valves to be located in the upper part of the neck of a container or container, that is, in the access mouth of said container through which a specific liquid is delivered or dispensed, where all cases count. with a series of components that allow the liquid inside to be dispensed adequately and quickly.

However, the devices found in the prior art present the problem that they require a specific location to allow the liquid to be dispensed, since they have channels in a location that become clogged if the container is not located in the desired way, which which limits its field of application. Additionally, vapors from these caps or lids do not allow easy use of the dispenser because they are not push and pull type, but rather have additional elements that make use highly complex.

Therefore, the above corresponds to existing problems in the state of the art that have not been solved by any existing document.

BRIEF DESCRIPTION OF THE INVENTION
