Abstract

There is described a child-proof system for a screw-on lid, particularly for containers provided with lids (1) of screw-on type, consisting in a screw-on lid (1) having at the end thereof a downturned stem (2), which stem (2) has a free end (3) with a curvature such that when the lid (1) is screwed on the neck of the vial (4), in the closing direction, the free end (3) of the stem (2), when the lid is almost in its final/screwed-on position, is forced over a ramp-shaped protuberance (5), where the stem (2) is secured at the end of the protuberance (5).

Description

"A CHILD-PROOF SYSTEM FOR A SCREW-ON LID"
The present invention refers to a new child-proof system for screw- on lids which prevents/hinders the opening of the lid by children.
The system that constitutes the object of the present invention preserves the physical integrity of children against opening the lids of health- hazardous products, such as hygiene and cleaning products, disinfectants, degreasers, combustible products, agricultural pesticides, among other toxic products, that would jeopardize their health or even their life.
The child-proof lids for containers have been known for a long time. However, there has been noted to exist a need to provide a new child-proof system, for screw-on type lids, which would be easy to open by adults and senior individuals, however preventing accidental opening by children. This system contributes to preserve the health and even the life of the children. According to statistics from the Brazilian Medical Association, one of the main causes of admission of children in hospitals is the ingestion of cleaning and general hygiene products of high toxicity.
The child-proof system that constitutes the object of the present invention is applicable to any type of container that is provided in the form of a screw-on lid and vial, screw-on lid and jar, screw-on Hd and squeeze-tube or any container capable of being fitted with a screw-on lid.
Therefore, it is an object of the present invention to provide, in a first embodiment thereof, a child-proof system for screw-on lids, particularly for containers provided with screw-on lids, characterized by consisting in a screw- on lid having at the end thereof a downward-directed stem, such stem having a free end with a curved shape such that when the lid is screwed onto the neck of the vial to close the same, the free end of the stem, when the lid is almost at its final closed/screwed position, is forced over a ramp-shaped protuberance, where at the end of the protuberance the stem is secured. Therefore, the lid can only be opened by means of two simultaneous movements that are: lifting the stem that is pressed onto the vial and at the same time turning the lid in the opening direction. This is the only form of accessing the contents of the container. It is important to point out that by merely effecting the movements independently, to wit, only raising the stem and/or only rotating the lid, it is impossible to open the latter.
An embodiment of the new child-proof system for screw-on lids according to the present invention is illustrated in the figures of the attached drawings, wherein:
Figure 1 shows a lid not yet screwed onto the vial, wherein the reference 1 indicates the lid, 2 indicates the stem, 3 indicates the end of the stem with a slight elevation that serves to raise the stem, 4 indicates the vial, 5 indicates the ramp-shaped protuberance and 6 indicates the backside of the ramp that has a sharp or inclined corner to lock the stem of the lid to the vial.
Figure 2 shows the lid partially screwed on to the vial at the preceding position of the stem, which touches the wedge-shaped protuberance of the vial.
Figure 3 shows the lid already screwed (prior to its final position), in the position where the stem is forced/tensioned upwards by the wedge-shaped protuberance of the vial.
Figure 4 shows the lid fully screwed onto the vial (sealing the vial entirely) with the stem at its resting position, having already passed by the protuberance, however exerting a slight pressure on the vial. In that position the lid cannot be opened (unscrewed) without raising the stem, since the same is abutted by the flat or inclined part (backside) of the protuberance.
Figure 5 shows the stem being raised to be able to pass over the flat part of the protuberance, with the lid being simultaneously unscrewed. Its is only by effecting both movements simultaneously, raising the stem and unscrewing the lid, that the latter is able to be removed from the vial.
Figure 6 shows the stem raised over the flat protuberance by means of a finger, releasing the lid to be opened.
Figure 7 shows the stem already entirely released from the protuberance, whereby the lid can now be normally unscrewed from the vial.
Figure 8 shows the lid fully separated from the vial.
Figure 9 shows a variant of that system, having at the back side of the ramp a small protuberance/lock 7 to further hinder the opening of the lid.
Figure 10 shows another variant of the system wherein the vial does not have a protuberance 5, having instead a ring 8 with a recess 9, and in this design the stem 2 is supported on the ring 8 prior to the position of engagement in the recess 9. As shown in Figure 11, the stem 2 is engaged in the recess 9 of the ring 8. The lid can be removed from the vial only by effecting the two simultaneous movements of raising the stem and unscrewing the lid.
It should be noted that the figures are merely illustrative, observing that the stem 2 can have various shapes; the ramp 5 can have various shapes; the backside 6 of the ramp can have various shapes. Preferably the lids 1 are made of plastic, however they may be manufactured from other materials such as aluminum, iron, etc.
The advantage of this system resides in the fact that the same prevents or renders substantially difficult the opening of lids of toxic product containers, thereby avoiding accidents involving children.

Claims

L A child-proof system for screw-on lids, particularly for containers provided with lids (1) of screw-on type, characterized by consisting in a lid (1) of screw-on type having at the end thereof a stem (2) oriented downwards, the said stem (2) having a free end (3) with a curved shape such that when the lid (1) is screwed to the neck of the vial (4), in the closing direction, the free end (3) of the stem (2), when the lid is almost reaching its final closed/screwed-on position, is forced over a ramp-shaped protuberance (5) or a ring (8) with a recess (9), where at the end of the protuberance (5) the stem (2) is secured or where the stem (2) engages the recess of the ring (8).
2. A system, according to claim 1, characterized in that there is a small protuberance/lock (7) at the backside of the ramp to further hinder the opening of the lid.
3. A system, according to any of claims 1 or 2, characterized in that the lid (1) can only be opened by effecting two simultaneous movements that are: raising the stem (2) that is pressed on the vial (4) and at the same time turning the lid (1) in the opening direction.
