Description

Container with an outlet valve.

The invention relates to a hood of container according to the generic term of claim 1 and a container according to claim 9.

There are many containers, particularly in bottle shape, widely used, provided with a hood according to the generic term of claim 1. They are used for example as bottles of mineral water in which the pressure is maintained mineral water using carbon dioxide, also dissolved partially in the water. Bowl caps usually serve to ensure a defined or dosed outflow of a fluid that is  found in the container, when a lever is operated opening.

This type of container with the hood corresponding is usually filled out by the manufacturer and it distributed in commerce, after gathering them in the form of packs, for example packs of 6 units, using a sheet of contraction.

In this type of packaging and supply of containers, a problem occurs, which is that at contracting the packaging sheet, involuntarily exerts a pressure on the opening lever found in the hood of the container, thus being able to escape from the gas or liquid container, which makes the container contents or the product can no longer be sold.

Particularly also, in the case of transport individual bottles of mineral water of this type, are usually frequently produce knocks or pressure on the lever corresponding opening, with the negative result mentioned previously.

In document CH 612 363 A5, a apparatus for the dosed output of materials in the form of gases, liquids and / or foams kept under pressure in a container of spray.

This device wraps the spray container by two pieces that can be firmly joined together, in such a way so that the spray container is maintained and placed in the inside of these pieces. The part of the device surrounding the container spray on its upper part has a head spraying, whose inlet hole is automatically embedded in inverse direction over the outlet opening of the spraying, when coupling the two pieces. The head of Spraying is rotatably housed around an axis, arranged at right angles to the longitudinal axis of the spray container, so that it stays in its position of resting by means of a positioning spring that can be carried to a spray position, against the spray container, beating down the positioning spring, by means of a trigger that protrudes from the top of the device and can be maneuver manually, when in the position of operating a safety pin, arranged parallel to the axis mentioned, pin that can be fixed by means of elements of positioned in a safety position and a position of functioning.

The described security device previously according to document CH 612 363 A5 is construction expensive. In addition to the safety pin itself, the positioning elements mentioned above, consisting of a screw safety, a spring located inside the screw security and an interlocking sphere, which cooperates, in the pin safety, with corresponding notches.

In addition, it is not guaranteed that on the packaging or the transport of a deposit provided with a device fluid distribution of this type, the safety pin remain in the "insured" position. If the pin of safety comes into contact, during packing or during transport, for example, for another purpose, there is a risk that the pin goes to the "uninsured position". This means that the container can be unintentionally emptied, if compressed the discharge lever (due, for example, to another container that It is in the transport packaging or the packaging itself).

In addition, the user of the CH document apparatus 612 363 A5 must recognize, as it protrudes laterally safety pin above the hood of the container, to the left or right, if the opening lever is in "security position" or "uninsurance". This it can lead to the user bugging errors and, for consequently, the lever is involuntarily operated.

What is intended with the present invention is offer a container hood or a container provided with hood of the type defined at the beginning, in which, with a high handling safety and a reduced construction cost, involuntary actuation of the valve is excluded unloading during packing or transport and improve reliability of the safety mechanism with respect to the existing one in the state of technique

In addition, what is intended with this invention is to configure, in the simplest way possible, from the construction point of view, the safety mechanism, with the in order to achieve the least number of necessary components, which, if compared with the state of the art means reducing notably production costs.

Furthermore, with the present invention, it is intended point the user of the hood of the container according to the invention, without having the need to associate with a position of "security" or "uninsurance" a feature such as the fact that the safety pin protrudes laterally, if the discharge valve is "secured" or "uninsured."

This problem is solved with a hood of container according to the generic term of claim 1 making the security element as a configured component in one piece with the hood of the container, be joined by articulation to said hood. With respect to a container, the problem is solved with the measures indicated in the claim 9, where a container of a hood has been provided according to the invention.

Due to the safety element of a piece, it reduce the number of components needed, if compared to known safety devices, which means a reduction of the costs. In addition, it increases the comfort of use, due to Simple construction and device reliability is improved of security.

The cap of the container according to the invention is you can perform particularly easily, manufacturing the safety element together with the hood of the container as cast iron part injected plastic.

The security element, in the case of a opening lever that is operated by pressure from above and / or laterally, it acts below the opening lever in a point not too far from the free end of the lever, of so that even if a large force acts for quite time on the opening lever, high safety is achieved, which prevents the valve from opening involuntarily.

The security element relies on the container, particularly bottle-shaped, but also it can be shaped like a drum, or conveniently, in a hood of container, fastened or placed on the neck of the bottle. In a advantageous embodiment, the articulated joint between the safety element and the hood of the container is formed by a hinge of sheets.

The security element can be configured advantageously as an almost rectangular or trapezoidal leaf, joined in an area of the edge by articulation with the piece superimposed by engaging the opposite edge area, in the position of sure, in a retention recess in the lever opening.

In an embodiment of the present invention, the edge zone of the security element corresponding to the retention recess has more or less U-shaped and comprises in particular a central retaining edge, relatively wide, and an area of the outer arm, narrow and elongated which, in the safety position of the element of safety, laterally wrap the opening lever.

In particular, the invention can be configured advantageously, making the opening lever present a upper section that widens towards the free end of the lever, which is reinforced at least by a rib of narrow reinforcement, which runs over the bottom of the lever in the longitudinal direction of it. This rib of reinforcement is then advantageously configured as a device of retention, since it has a retention notch, in the which can fit the security element in position of safe.

In order to secure the container in the form of bottle, so that it does not support an unwanted drive of the discharge valve, even after transport, the element of security can be in contact, in an orientable way, with the cap of the container and fit or lock preferably. East embedded can be done, for example, by a highlight of retention and a corresponding retention recess or by some fasteners, which may be formed, both in the security element as well as in the hood of the container.

Therefore, the security element can turn to a release position, after transport or after removing the container from the foil container of contraction, in which it is maintained and from which it can return in every moment to the security position, which is advantageous when the container has to be transported again in question.

In the hood of the container, they have formed conveniently two highlights, separated from each other, preferably verticals, which can retain between them the element of security.

The safety device according to the invention It is particularly suitable for mineral water bottles, in which mineral water is kept under pressure, preferably with gaseous carbonic acid.

The following describes in detail the invention based on an exemplary embodiment, in which Refers to the figures:

Figure 1 shows a schematic section of a bottle-shaped container, with the characteristics of the present invention;

Figure 2 shows a sectional representation of the area, with the bottle cap according to figure 1;

Figure 3 shows a perspective view of the hood of the container, where the security element occupies an intermediate position, as in figure 2;

Figure 4 shows a perspective view of the hood of the container from another point of view;

Figure 5 shows a perspective view of the hood of the container, where the security element occupies its security position; and

Figure 6 shows a perspective view of the hood of the container, in which the security element It occupies a position of liberation.

In figure 1, a shaped container is shown bottle, usually designated with the number 1. Bottle 1 it has a cavity 2, in which a flexible tube 3 penetrates to the background. The bottom of the container (4) has a concave vaulted inwards, in the embodiment shown. The bottle 1 has a neck 6, closed with a cap 5, in which a valve insert 7 is incorporated, hermetic to the medium. The cap of container 5 may be formed by a threaded piece, provided with internal thread or (depending on the embodiment shown) provided with an inner annular retention shoulder 14, which cooperates with a complementary retention shoulder 14a in the the neck of the bottle, to keep the hood of the container, in safe contact with the neck of the bottle. He valve insert 7 encompasses a valve 10, which has a upper valve pusher 17, which extends into a housing of the valve pusher 11 of a part of the lever, with a opening lever 9.

Valve 10 is represented more accurately in figure 2 and comprises a valve seat 16, a body of valve 18 and a spring element 19, in the form of a spring helical, which keeps the valve body 18 compressed against the valve seat 16. Pressing the lever opening 9, the valve pusher 17 moves down overcoming the return force of the spring element 19, due to which can circulate through flexible tube 3 to a tube of outlet 9, a liquid that is inside the container in the form of a bottle, which is under pressure (for example mineral water  mixed with CO 2).

In the exemplary embodiment shown, they have configured in the hood of container 5 articulated areas 22 (see figure 2), formed for example by thin sections from the wall of an outlet pipe, so that it is possible actuate the valve 10 by pressing the opening lever 9 due to  This elastic joint.

In the hood of container 5, it has been joined by articulation a safety element 13 to an edge area, is say with an articulated joint 15, configured as a hinge of sheets. The security element 13 can rotate around the articulated joint 15, adopting various positions, in particular a safety position, shown in figure 1 and in the Figure 5. The security element 13 is formed by a foil trapezoidal, with a U-shaped free edge zone, which has a relatively wide central retention edge 13c and arm sections 13a and 13b, exterior, relatively narrow.

The opening lever 9 is configured so which gradually widens towards its free end, such as it can be seen in figure 3. This upper section, which goes away widening, of the opening lever 9, is reinforced by a reinforcement rib 19 (see figure 4), configured in its lower surface, which extend in the longitudinal direction of the lever 9. Near the free end of the opening lever 9, a recess is formed in this reinforcement rib 19 notched 12, in which the retaining edge fits 13c of the security element 13, in the safe position. How I know it follows in particular from figure 5, the lateral sectors outer arm 11 a and 11 b laterally wrap the lever opening when the safety element 13 is in the position of safe.

In the position of the security element 13 which shown in figure 2, the hood of the container 5 is manufactured by an injected casting process and the element of Safety 13 is manufactured in the position shown in Figure 2, transversely separated about 45 ° from the cap wall of the container 5, so that it is attached, in one piece with the hood of the container 5, by means of the sheet hinge fifteen.

Before packing bottle 1 in sheets of contraction, the safety elements are put in the position of safe shown in figure 1 or 5.

After removing the container from its packaging, for example of the contraction sheet, the safety element 13 from the position indicated in figure 5, whereby the two arms 13a and 13b can serve as a handle.

As you can see particularly in Figure 5, in the outer peripheral area of the hood of the container 5, you have configured a clamping device in the form of highlights elongated 21, which extend vertically and are arranged and shaped to keep security element 9 in  a release position, shown in figure 6.

This is achieved by making highlights 21 be engage with a retaining shoulder 20 in the element of security 9, serving the space between the highlights 21 as retention recess to accommodate the retention shoulder 20.

In the construction according to the invention, there is the possibility of re-securing the lever at any time opening 9, if you have to transport again for example the container in question. To do this, just take out the element of security of its release position, shown in figure 6 and compress it below the opening lever 10, until the retaining edge 13c fits the notch 12.

As the technician will appreciate, it is possible all a series of variants of the exemplary embodiment shown, without thereby departing from the scope of the present invention. So by For example, the present invention is not limited to the configuration that The security element is shown and can be configured in very different shape, for example as a rod or as a bar round, which fits into a corresponding recess below the opening lever, in safe position.
