DESCRIPTION:
BRIEF SUMMARY
PURPOSE OF THE INVENTION
This invention relates to a container, which has been especially designed to hold clinical waste, equipped to form a hermetic seal, which on the one hand proves to be workable during the container-filling phase, while at the conclusion of same, said seal proves to be inviolable, ensuring an absolute inaccessibility to the clinical waste housed therein.
BACKGROUND OF THE INVENTION
In the clinical and hospital setting, waste is generated which may prove to be hazardous, sometimes because it is harmful to the health, as occurs with certain chemicals, and in other cases because it is capable of causing accidents, as happens with injection syringes and other objects.
For its disposal, this type of waste requires a container which ensures inaccessibility to the interior thereof from the clinical center in which it is produced until its final disposal.
There are known in this sense rigid or semi-rigid plastic containers, constructed with a main portion and a cover capable of being coupled hermetically, said cover furthermore being provided with a workable mouth through which the waste is poured into the interior of the container, until the latter is full, which mouth is provided with a movable shutter which makes it possible to keep the container sealed between successive manipulations for depositing of waste, which shutter, after the final filling of the container, is capable of being secured immovably, as for example through a fastening mechanism, which now makes the contents of the container inaccessible once and for all.
The containers of this type known to date do not afford optimum guarantees of leak-tightness or of inviolability of the seal, or else they have very complex structures, which make them very considerably more expensive.
DESCRIPTION OF THE INVENTION
The hermetic container for clinical waste which the invention proposes constitutes a simple and effective solution, which ensures on the one hand an optimum leak-tightness in the coupling between cover and main portion, and which similarly also affords optimum conditions of leak-tightness during the period of use of the container; that is, during the period of receiving of clinical waste until its filling, with the possibility of easy access to its interior, moreover having means for final sealing which make it absolutely inviolable.
Accordingly and more concretely, the container which is contemplated is constructed based on a main portion provided in the area of its mouth with a skirt arched outward and downward, which main portion is completed with a cover which, also at its mouth, embodies a narrow groove in which the mouth of the main portion fits tightly, from the outer edge of which groove there projects another arched skirt, complementary of that of the main portion; that is, positioned in the same direction, but of greater length and with an inner perimetria flange designed to extend beyond the free edge of the skirt of the main body, so that cover and main body prove to be easy to couple by mere pressure, but their subsequent separation proves to be extremely difficult, practically impossible.
On the other hand, the cover is provided with a circumferential groove, with a throttled mouth, in the cavity of which there moves a disk mounted freely rotatable on the cover in contact with the center of the aforementioned circumferential groove, which disk has a perimetria flange which fits through pressure into the aforementioned groove, so that said disk can rotate freely with respect to the cover itself, but remains immobilized in the axial direction.
In order to achieve this rotatory movement of the disk with respect to the cover, said disk has a manually activated outer fin, located on its periphery, and with an inner lug which moves in a second groove of the cover, in this case semi-circumferential, the ends of which act as rotation-limiting stops for the disk which, consequently, is capable of rotating only approximately 180.degree., in one or the other direction.
This relative rotatory movement between disk a
