MXPA00010054A - Plug for receptacles containing evaporable liquids - Google Patents

Abstract

The plug comprises a body (1) that can be permanently coupled to the mouth or neck of a receptacle containing an air freshener or insecticide liquid. Evaporation is effected by means of a wick (11) axially coupled to a concentric passage of said plug. An inner part of said axial passage of the plug, in which the wick (11) is located, has two notches (7) in the direction of the generatrix forming sectors (9) fitted with semi-pyramidal ribs (12) which define means enabling displacement in the direction of the insertion of the wick (11) and preventing displacement in the direction of removal or release of the wick (11) relative to said plug, thus preventing the receptacle on which said plug is applied to be refilled with a product different from the original product.

Description

SHUTTER FOR CONTAINERS CONTAINERS OF EVAPORABLE LIQUIDS D E S C R I P C E N 5 OBJECT OF THE INVENTION The invention relates to an obturator applicable in container containers of liquids intended for evaporation, for use with or for the purpose of setting and / or for the elimination of insects, or similar applications, a shutter that is complemented with a wick through axially through of the same, leaving a part of such a wick submerged in the liquid contained in the container and another part emerging to the outside and through which the evaporation of the product contained in the container takes place. It is the object of the invention to provide a shutter that makes filling of the container impossible, by having means that allow axial assembly in the direction of introduction of the wick but that make it impossible to remove them or render them unusable. That is to say, the obturator has as one of its fundamental characteristics being endowed with internal elements that allow the axial displacement in one direction of the wick and make it impossible to move in the opposite direction, in order to prevent the extraction of said wick once mounted on the obturator, and therefore prevent filling of the container with another liquid that is not the original, since said obturator is of the type that are permanently mounted on the neck of the container, with no possibility of independence.

BACKGROUND OF THE INVENTION There are numerous devices or means used for the evaporation of liquid air fresheners, either to provide a pleasant environment in an enclosure, or to flood that environment with a product that attacks insects for the elimination of these.

Among the numerous types of systems used, it is known that the outlet to the outside of the effluvia contained in the corresponding container is made through a wick mounted on a shutter coupled on the neck or neck of the container itself, so that a The end of the wick is immersed in the liquid content of the container while its other end emerges to the outside to allow the evaporation of the liquid.

Well, this type of shutters can be mounted on the neck of the container permanently, that is, in such a way that its independence is practically impossible unless its rupture or deformation is carried out, which prevents a new coupling right of the obturator on the container.

Now the wick, which is usually mounted on an axial hole in the obturator, can be easily assembled and disassembled, which allows the container to be filled with a liquid different from the original, once it has been exhausted, which results in a lack of safety, since this new filling liquid, which is not the original, can be harmful or harmful to the use that is going to be given, such as flammability, toxicity, corrosion of plastic, electrical components, etc. .

In addition, the fact that the wick can be independent and 0 coupled at will on the obturator, carries with it a serious problem and inconvenience, since in the children's eyes it turns out that they can extract the wick, attracted by the good smell of the content of the container, and not only that they carry the wick to the mouth with the consequent risk, since the product is usually toxic, but they can also ingest the contents of the container after the wick has been separated or extracted from the obturator.

A type of protective device for a wick is known, through which the evaporation of an environmental liquid contained in a container takes place, and which is described in patent WO 98/00177, in which the obturator is or integral with a plastic cap that covers the outside of the wick, all in order that it is perfectly protected by the aforementioned cap and prevent children from sucking or ingesting the liquid with which this wick is impregnated, the cap having to be independent, through the suitable means and by an adult person, to leave the wick with a part to the outside to allow the evaporation of the liquid content of the container in which the obturator itself is applied, which evidently does not eliminate the risk that once the wick is unsealed of the container, by breaking the corresponding cap, the child can extract the wick and carry out the ingestion of the contents of the container.

DESCRIPTION OF THE INVENTION The obturator that is advocated has been designed to solve the problems described above, based on a simple but considerably effective solution, since it is based on having means that make it impossible for the wick to be independent or removed from the obturator, which prevents the filling the container in which the obturator in question is applied.

More specifically, the obturator of the invention, as is conventional, has an annular body with a throat facing inward, in which the upper edge corresponding to the mouth or neck of the container is located and retained, said shutter being permanently mounted on that neck or embouchure of the container, with the particularity that the obturator in question has concentric with a neck that emerges slightly towards the outside, and another that emerges and extends axially toward the interior, with a series of cuts in the direction of the generatrices, determining sectors destined to embrace and press the wick, constituted preferably by a cylindrical body that is through this axial passage of the obturator, complementing the internal part provided with the 5 sectors that embrace and press against the lateral surface of the wick, with another concentric neck, of slightly larger diameter, also with cuts in the direction of the generatrices, which press on the previous ones when the obturator is coupled on the neck of the container.

In order to prevent the wick from being extracted, that is to say, to move in the direction of independence from the obturator, it has been foreseen that on the determined sectors in the axial and inner neck pressing against the lateral surface of the wick, there are projections of triangular profile, or what is the same of semi-pyramidal configuration, whose vertex is in an internal zone or lateral surface of each sector, so that the lateral surface of such projections diverges towards the interior, defining ramps that make possible the sliding or displacement in one direction of the wick, but preventing the displacement of such a wick in the opposite direction, or what is the same prevent the wick once introduced on the obturator can or be extracted, unless by a strong traction of the same, which would produce the breakage of it being unused, so that the obturator would also be unusable as it should be always complete with its corresponding wick to achieve the evaporation of the liquid contained in "-to.",... the container, hence the fundamental characteristic that the obturator is non-refillable, with the consequent advantages that derive from it, such as preventing it from being filled with a liquid other than the original, and preventing children from being able to remove the Wick and ingest the contents of the container.

DESCRIPTION OF THE DRAWINGS To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization thereof, an assembly of drawings is included as an integral part of said description. With an illustrative and non-limiting character, the following has been represented: Figure 1 shows a side elevation view of a shutter for evaporative liquid containers, made according to the object of the present invention.

Figure 2 shows a bottom plan view of the same obturator shown in the previous figure.

Figure 3 shows a top plan view of the obturator shown in figure 1, clearly seen as in figure 2 the internal projections of triangular profile with which are provided sectors that they wrap and press against the wick through which the evaporation of the liquid contained in the container in which the obturator itself is applied takes place.

Figure 4 shows a sectional view corresponding to the cutting line A-A of figure 2, with the wick coupled axially on the concentric passage determined in the obturator itself.

Figure 5 shows another view in section, in this case according to the cutting line BB of Figure 3, also including the wick, which as in the previous figure can be seen as being displaceable in the direction indicated by the arrow, but It is impossible to move in the opposite direction, which prevents such a wick can become independent or removed from the obturator.

PREFERRED EMBODIMENT OF THE INVENTION As can be seen in the figures referred to, the shutter of the invention, applicable to containers for liquids to be evaporated to set a room, or for the elimination of insects, in case the product has the corresponding properties, includes an annular body (1) in which an internal annular groove (2) is formed, with a projection (3) facing inwards, and projections (4), determining means of coupling and retention on the corresponding neck or mouth of the container in which said obturator is applied, with the particularity that the body (1) has a neck (5) that emerges slightly towards the upper and outer part of the body of the shutter concentrically. (1), while inferiorly, that is, in the opposite direction, it extends into another internal neck (6) with cuts (7), in the direction of the generatrices, so that these cuts of the internal and axial neck (6) they are also made in the wall (8) of shorter length than that determined by the internal neck (6), although of greater diameter, leaving that wall (8) or ring wall and neck wall (6) concentric with each other and affected in both cases of the cuts (7) in the sense of the generatrices, forming in each case sectors (9) and (10), respectively.

Well, from this structuring, the corresponding wick (11), constituted by a cylindrical body, is passed through the axial and concentric neck of the described obturator, in the direction indicated by the arrows shown in figures 4 and 5 , that is, in the direction of introduction to the corresponding container in which the obturator itself is applied.

Well, to prevent that wick (11) can be removed, or rather, that is prevented from traveling in the opposite direction, it is provided that the sectors (9) of the concentric neck (6) determining the axial passage, sectors (9) ) that press the wick itself (11), are equipped with semi-pyramidal projections (12), of triangular profile, as can be seen clearly in the figures, so that in correspondence with the innermost parts of the surface of the sectors (9) the projection starts with a zero level to ¡r determining the semi-pyramidal configuration, that is, increasing in width, which defines a kind of ramp that allows, as said, the displacement in the direction of introduction of the wick (11), so that if it is intended to extract it, that is, move it in the opposite direction, then the semi-pyramidal projections (12) will impede it, when nailing itself on the lateral surface of the wick (11), it can not be extracted unless it breaks by tearing, when make a strong pull of it.
