DESCRIPTION:
BRIEF SUMMARY
This invention refers to a plastic safety stopper used for the sealing of glass, plastic or carton bottles or various other types of containers. Its outflow opening, does not open immediately and it can remain open only for as long as it is desirable. If not used, the product stays firmly closed since the outflow opening is covered by a self returning slide cover in its original position without the need of a special move from the user. The head of the stopper with its operation mechanism and the slide cover is a single inseparable compact unit.
There are many types of stoppers, lids and caps available in the market for a vast array of applications, most if not all of them are known to allow for easy opening of the container they are meant to close and to further remain in the "open" position. It remains in the open position until it is manually closed by the user.
The Intoxication Ailments Clinic at the "Aglaea Kyriakou" Children's Hospital in Athens has published a revealing report on the number of intoxication cases. This is increasingly due to the tragic defects that such regular types of bottle stoppers have been found to present. More specifically, in the year activities report of this Hospital for year 1993 published in Athens in 1994, it was mentioned that the emergency service had, over 1993, received as many as 30.635 calls for intoxication's, 10.715 of which involved minors between the age of 2-4. Many of them had opened such stoppers of containers having medicine or domestic use products (i.e. detergents, cosmetics etc.) Home has been quoted as one of the most common areas where intoxication occurs (26.201 cases, 85.5%) such an unbelievable high rate of cases treated at the clinic solely and exclusively represented intoxication cases (other types of cases such as burns etc. are not included in the figures quoted above)
According to this invention the stopper can only open by persons who have the skill to do so and not by children. An other advantage of this invention is that the safety stopper can remain open only for as long as the contents are required to flow and it returns to the "close" position automatically. The head of the stopper with its operation mechanism and the slide cover is a single inseparable compact unit.
Set fourth below is a description of a particular application of the invention available, appropriately referenced with a series of figures meant to explain the way in which such idea may be materialized.
"FIG. 1" shows a plan of the plastic safety stopper according to the invention
"FIG. 2" provides the same aspect as the one shown in "FIG. 1" although the slide cover of the stopper it is not into the function position.
The safe stopper shown on these figures applies to closed bottles, containers, etc. Size and shape may vary according to the parameters of the application required. The stopper consists of a head (K) with an out flow opening (H) its size and shape is in proportion with the out flow rate and supply, even in case the contents is pharmaceuticals.
From head (K) are extended two arms (E1) and (E2) both of which are connected to presser (O). In its turn, the presser is connected to slide cover (F) with a membrane (M). The slide cover (F) rotating around the membrane (M) fastens into the guides (D1) and (D2). At the same time the grooves (T1) and (T2) of the slide cover (F) fit to the projections (Z1) and (Z2) of the presser (O) so the slide cover (F) seals the outflow opening (H).
More specifically as far as the slide cover is concerned, groove (A) and projection (S1) have been arranged in such a way as to allow the slide cover to slide along guides (D1) and (D2) as soon as pressure is exercised upon the presser (O), eventually reaching a position where projection (S1) becomes adjacent to the head (K) while groove (A) is simultaneously positioned above the out flow opening (H) of the stopper. In this way, the opening is fully uncovered allowing the outflow of the contains of the bottle, container etc.
