Description

DESCRIPTION

PROTECTIVE CAP FOR AEROSOL

As its name indicates, the invention refers to a cap used to close an aerosol can, preserving the outlet valve during transport, storage or handling operations before or after spraying.

As a general rule, aerosol caps require both hands to open since while holding the aerosol bottle with one hand, the cap is pulled with the other. This operation usually requires some force since the caps are generally anchored to the aerosol can with a strong enough joint so that a fortuitous blow does not make it pop, leaving the valve exposed.

The proposed invention allows the lids to be opened with just one hand, which is an advantage especially in circumstances in which one of the hands is occupied.

BACKGROUND

Aerosol can caps have been known for years. These caps protect the valve from unwanted pulsations, however, for the user they represent a problem since it requires both hands and some force to be able to remove them, access the valve and press it.

To solve the aforementioned problem and facilitate the tasks for the user, lids have been developed that incorporate pushbuttons, that is, mobile elements that can activate the aerosol valve without the need to remove the lid. They are known as actuator caps.

To give some examples from the patent literature, we find the Australian patent AU54836, the British patent GB2099513, the Spanish patent ES453891 or the US patent US3651993.

Another option to facilitate manipulation by the user, are the actuator covers that have a practicable area, like a hatch or door, which allows access to the valve. Examples of this type of solution are patents DE19960846, ES412073 or GB1400177 among others.

All these solutions require complex covers, with mobile elements, superimposed and reinforced structures in some points to counteract the weakness caused by the practicable areas, for all of which a high consumption of plastic material is required.

To overcome the problems exposed, a cover is proposed that allows its removal with one hand, allowing the user to access the valve and proceed with spraying without the need to use both hands.

DESCRIPTION OF THE INVENTION

An aerosol cap is proposed that comprises a closed upper base and an open lower base, both bases being joined by a perimeter wall that can be smooth, or present recesses or various shapes where that perimeter wall is conceptually divided into a skirt and a elevation, the skirt being the lower part of that perimeter wall and the elevation being the part of the perimeter wall between the skirt and the upper base of the lid.

The inner part of the skirt contains the means for anchoring the lid to the aerosol can.

Also in this skirt, and open towards the lower base of the lid, we find a notch that favors the deformation of the lower part of the lid when lateral pressure is exerted on it, above the notch, facilitating its opening. In addition, the material of the cap is generally flexible, a plastic material, which allows for plastic flexibility.

In light of the above, the protective cover comprises:

- A closed top base.

- An open bottom base.

- A perimeter wall that joins both bases, this wall comprising a skirt area and an elevation area.

- In the skirt area there are anchoring means to guarantee the union of the lid with the aerosol can.

- An open notch towards the lower base of the lid.

- A pulsed zone on the notch. This pulsing zone can be visually differentiated.

By exerting a force on the pulsing zone, especially if that force is upward lateral, the lid is deformed, the anchoring means are released, the lid is separated from the aerosol container.

In a possible embodiment, the anchoring means comprise a series of projections in preferably semi-lenticular on the inside of the skirt area. These projections are horizontally aligned arranged at a certain distance from each other, this alignment being interrupted in the area of the notch.

In another possible embodiment, the anchoring means comprise a continuous horizontal inner bead along the entire inner perimeter of the lid in its skirt area, but interrupted by the notch.

This arrangement favors that the joint between the lid and the aerosol container is resistant to vertical traction and to any pressure exerted laterally that is not in the pulsing zone but, nevertheless, in the face of the pressure exerted in the pulsing zone, precisely by the absence of the anchoring means in the area of the recess makes it easy to detach it from the aerosol container.

BRIEF DESCRIPTION OF THE FIGURES

Figure 1 shows an execution of the cover (1) in which the perimeter wall (2) that joins the closed upper base (3) and the open lower base (4) is smooth. This perimeter wall has a lower part that we will call the skirt area (5) in this case the part of the perimeter wall that is below the inner ring (12), and an upper part that we will call the elevation area (6 ), in this case there is no visual differentiation between them on the outside.

In the skirt area (5) on its inner face, we find the anchoring means (7), in this case some projections towards the interior with a semi-lenticular shape, although in another possible execution it may be an internal bead. Also in this area of the skirt, the cover has a notch (8) open towards its lower base (4).

The area of the perimeter wall located on the recess on its outer face is the pulsing area (9), although in this version it does not appear visually differentiated.

Figure 2 shows a possible execution of the cover (1) where the junction between the perimeter wall (2) and the upper base (3) is chamfered, without affecting the functionality of the cover.

Figure 3 shows a possible execution of the cover (1) where, among others, the skirt area (5), the elevation area (6) and the pressing area (9) arranged on the notch ( 8).

Figure 4 shows another possible embodiment in which the cover (1) has two lateral bites (10), without this altering its functionality.

Figure 5 shows an execution of the cover (1) which in this case has, among other elements, some anterior posterior bites (11), a pulsing zone (9) which in this case is visually differentiated, and a notch (8 ) in the vertical of said pulsing zone in a lower position.

Figure 6 shows the cover (1) from another angle that allows to appreciate the skirt area (5) and the elevation area (6) divided by the ring (12) the anchoring means (7) in this case semi-lenticular projections towards the inside the lid arranged in a line that is interrupted by the notch.

DESCRIPTION OF A MODE OF CARRYING OUT THE INVENTION

A mode of carrying out the invention is described below that is not unique but merely explanatory, so it cannot imply a limit to the inventive concept.

A lid is proposed for closing an aerosol container that offers a good anchoring during transport, storage and handling operations, being resistant to vertical traction as well as lateral pressures but nevertheless, exerting a pressure at a given point, specifically in the pulsed area (9), it is easily detached from the aerosol container.

For this, the cover (1) comprises:

A closed upper base (3), although it may have small spray or ventilation outlet holes.

An open lower base (4).

A perimeter wall (2) that joins the lower and upper base, this perimeter wall presenting a skirt area (5) below the ring (12) and a raised area (6) between the ring and the upper base.

In the skirt area (5) we find the anchoring means (7) and a notch (8) open towards the lower base (4).

The anchoring means (7) are arranged on the inside face of the skirt area (5) and comprise a series of semi-lenticular geometry elements projected towards the inside of the lid. In another possible embodiment, instead of a plurality of elements, it can be a continuous inner bead which is interrupted in the region of the recess. These semi-lenticular elements are separated from each other, aligned horizontally and distributed horizontally along the inner perimeter of the lid to Except where the notch (8) is located, where the line of anchor elements is interrupted.

Above the recess (8) there is a pulsing zone (9) that may or may not be visually defined.

When pressure is exerted, preferably laterally upward, on the pulsing zone, the cover deforms, the anchoring points are unmoored and the cover is free to be removed with little resistance.

The lid admits various configurations, from the purely cylindrical, to other types of configurations with setbacks, lateral bites (10) or anterior posterior (11), or even be bell-shaped as shown in Figure 3, without diminishing the mechanics of the lid.
