Definitions

• the present invention relates to a safety device which can be used as a means of closing the various types of containers of current manufacture, or of packages, in the form of flasks, bottles, or tubular structures, intended for storing any product, under liquid, solid form, as well as pulverulent materials, more particularly, toxic or dangerous products for living beings.
• the same safety closure system with a few simple adaptations, can be used as a safety closure for the tanks of motor cars, for the storage tanks of any fuel, or other products, which makes it possible to avoid a key, since it is easy to remember the confidential code number and opening procedure.
• this device with a few additional adaptations, can be adapted as security for sockets or mounted on locks, in order to prevent the introduction of the key. If the device code is not known, the keyhole becomes inaccessible.
• Packaging with a security closure is not a completely new problem.
• Security systems using friction locking, or locking by a push button, or by any moving element have already been used in the past, more particularly in the United States of America, with relative success.
• the patents: US 36566-1-7, US 2226390 and US 3451576 disclose quite interesting solutions. Although these solutions provide sufficient security for children under the age of six, these systems are opened quite easily by children of older age, since they have already learned to read and have become pretty smart playing with modern toys. Thus, by observing their parents opening these packages, even though they have a security system, they quickly learn to open them too. This is why the present invention aims to achieve a closure system more difficult to open, not only by children, but also by adults.
• this closure means allows it to be easily adapted to packaging, of tubular shape, of current manufacture. Because this system can be manufactured as an additional element, mass production, without the need for major changes to the installations used for the manufacture of standard packaging, is possible. In addition, the possibility of other uses mentioned above makes it possible to have a more versatile product, which can be produced in very large series, which greatly reduces the cost price.
• the present invention relates to a safety device for closing containers such as commercial packaging used for medicines or for toxic products etc.
• This device can also be mounted on containers which are already closed with their original caps.
• This closure system comprises a first cylindrical element free to rotate, but retained on the body of the container, so as to avoid an upward displacement, which first element can be provided with a labyrinth on its cylindrical surface.
• This labyrinth is made up of a combination of horizontal and vertical slots, placed in different angular positions.
• Said device further comprises a second element constituted by two cylindrical walls connected together and arranged coaxially, so as to delimit an empty space between these said walls. This empty space is intended to house said labyrinth.
• Said second element also includes a central chamber which is closed by an easily removable cover.
• a locking means consisting of a third element of square section, is disposed inside said empty space, which element is integral with the two aforementioned walls and can, at the same time, slide inside the slots of said labyrinth when the 'said second element is rotated.
• the design of the labyrinth of the closing system is such that, to open or to close this system, one is obliged to handle said second element according to a preselected program, respecting the code numbers engraved or printed on the various elements.
• the program, as well as the positions of the code numbers can be changed easily during production, either by modifying the angular positions of the vertical slots of the labyrinth, either by modifying the angular position of said locking element relative to the code numbers, or both at the same time.
• the slotted labyrinth can be replaced by two coaxial flanged cylinders.
• Each flange comprises at least one slot which can work with a square protuberance to produce locking when the two coaxial cylinders are turned, to offset said slots relative to said protuberance. If you want to make the opening more difficult, it is preferable to use two slots of different width, working with two protrusions of square shape. Each protrusion width then corresponds to the width of the corresponding slot.
• FIG. 1 shows a vertical section of a first embodiment of the device, showing the detail of the elements used.
• FIG. 2 shows the device seen from the outside.
• Figure 3 shows the top view of Figure 1.
• FIG. 4 shows the cylindrical element (2) of Figure 1, in developed form, clearly visualizing a slot constituting a labyrinth.
• FIG. 5 shows a second possible embodiment using the same principle.
• Figures 6 and 7 show element 105 of Figure 5.
• the reference (1) represents a cylindrical part, such as a tube for medicaments, or the neck of a flask or a bottle, provided with a flange capable of receiving the element (2). of the closing device.
• the container (1) can already be closed by a usual plug (7); and the object of the present invention is to prevent access to the plug '(7) without removing this device.
• Said cylindrical element (2) is designed so as to be retained by said flange on the element (1), to prevent any upward movement.
• the cylindrical wall of this element (2) is provided with a labyrinth-shaped slot, the operation of which will be described later.
• the element (3) is composed of two cylindrical walls, arranged coaxially and connected to each other in an integral manner, thus constituting a recess between these two said walls to house the part containing the labyrinth of the above-mentioned element (2).
• the element (3) comprises, in the middle, a chamber (13) which can be closed by a plug (6), removable. Said chamber (13) can be used to keep a notice, daily marks, etc.
• a locking element (4) preferably of square shape, is placed integrally between the two said walls of the element ( 3). The element (4) is made to slide in the slots of the labyrinth represented by the references (10), (5), (11) and (12) of FIG. 4.
• the element (3) comprises, on its surface cylindrical outer, a graduated scale, as shown in Figure 2, with the numbers (1 ', 2', 3 ', etc.) and an index (9) placed on the flange of the element (2), which flange is integral with the wall comprising the labyrinth.
• the opening and closing of this device requires the manipulation of the part (3), according to a predetermined program fixed by the structure of the labyrinth.
• the lock (4) is in position (A), in the slot (10) of the labyrinth, as shown in Figure 4. This position corresponds to n ° 6 ', opposite the index (9) (Fig.2). If the element (3) is pulled upwards, the locking element (4), being integral with the part (3), can pass into the slot (5).
• the element (3) If, still retaining the part (2), the element (3) is turned in the direction of the arrow (F), to bring a number chosen on the scale (8), which number corresponds to the position (B ) from the labyrinth, the element (3) can be pushed down, which makes it possible to bring the locking element (4) into the slot (11). If the element (3) is continued to rotate, still holding the part (2), in the direction of the arrow (F), the locking element (4) can be brought to position (C) from the slot (11). This position can be identified by a reference number corresponding to the scale (10 ') of the scale (8) indicated on the surface of the element (3).
• the locking element (4) When the locking element (4) is in the position (C) of the slot (11), the element (3) can be pulled upwards, which makes it possible to bring said locking element ( 4) in the slot (12). Then you can continue to rotate the element (3) in the direction of the arrow (F), to bring the locking element (4) into position (D). This position can be identified by another figure chosen from the scale (8) of the element (3). Then, if the element (3) is pulled upwards, the locking element (4) can come out of the labyrinth through the slot (E). This completely frees the assembly formed by the elements (3) and (6) from the element (2) and by sliding this element (2) down, you can access the stopper (7), therefore the contents of the container. .
• the opening procedure can be expressed by the following maneuver program:
• the system is remarkable by the fact that, if one does not know the opening code as well as the opening process and if one tries to turn the element (3) to the right or to the left, the stop locking device (4) slides freely in the slot (10). Each time the stop is at one or the other of the ends of the slot (10), the whole device rotates freely, without opening the container.
• This first embodiment makes it possible to obtain a tamper-evident closure device, of simple construction.
• This device can be made, either of resistant plastic, or of stainless steel, or of aluminum, or of any suitable material, depending on the application.
