Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a disposal container in which stored items are not spilled to the outside no matter how they are handled during a disposal operation.

[0002]

[Prior art]

 For example, needles and syringes contaminated with blood, used ampules and vials, and any medical waste are stored in waste containers and discarded. Since the attachment of the container body and the lid of the conventional disposal container was performed only by simple means, the following problems occurred.

[0003] When disposing of waste containers full of waste as industrial waste, they are temporarily stored in a warehouse of an industrial waste trader, and are sequentially transported by truck to an industrial waste treatment plant. Especially in the summer months, if stored in a high-temperature warehouse, blood, infusions, liquid foods, etc. that adhere to or accumulate on dirt (cans, bottles, bags, etc.) in the container will be putrefactive and fermented. And the increased internal pressure exceeded the engaging force of the lid, sometimes blowing off the lid and causing the contents to scatter around. In addition, unlike general products, industrial waste is often handled in a rough manner, and in the process, the lid comes off and the contents are scattered around.

[0004] These medical wastes include bacteria that are harmful to the human body, such as being infected with AIDS when accidentally stabbed into the human body, such as a used injection needle to which AIDS bacteria have adhered. Attention has to be paid to the handling of such materials, but at present, such attention is rarely given to waste. In addition, the rotten odor of the filth is intense, and there is also a problem that if the sealing force of the lid is weak, the odor leaks and the odor is scattered around.

[0005]

[Problem to be solved by the present invention] The problem to be solved by the present invention is that once the lid is closed, it cannot be opened until it is broken, it can withstand the internal pressure sufficiently, and the leakage of odor is completely shut off. The development of waste containers that can be used.

[0006]

[Means for Solving the Problems]

 The container for disposal (A) according to claim 1 is (1) a container body (1) having a bottomed cylindrical shape and an outer flange (2) protruding from an outer periphery of an upper surface opening (4). And a lid (10) having a mating engagement portion (11) engaged with the outer flange (2) in a mating shape, and a lid (10) closing the upper surface opening (4). In (A), (2) the outer flange (2) has an engagement projection (3) on the lower surface of the distal end, and (3) the fitting engagement portion (11) has a base (12). A substantially U-shaped engagement groove (13) is formed to be flexibly attached and engage with the engagement protrusion (3) when the flexible base (12) is bent. (4) A convex ridge (5) and a concave groove (14) are formed over the entire circumference on one of the contact surfaces of the container body (1) and the lid (10), and (5) the concave groove ( 14) A packing (15) that is in close contact with the convex ridge (5) is provided inside.

[0007] According to this, when the fitting engagement portion (11) of the lid (10) is bent, the engagement projection (3) on the lower surface of the distal end of the outer flange (2) is engaged with the fitting engagement groove (13). The fitting engagement portion (11) firmly holds the outer flange (2), and is fixed in the fitted-in state. As a result, the lid (10) does not come off even when the internal pressure of the waste container (A) rises due to the decay and fermentation of the waste contained in the waste container (A). As long as (A) is not damaged, its contents will not be scattered outside.

In addition, a convex ridge (5) and a concave groove (14) are formed on one of the contact surfaces of the container body (1) and the lid body (10), and the concave groove (14) is formed. Since the packing (15) that is in close contact with the convex ridge (5) is provided inside the container, the tight fit between the container body (1) and the lid (10) is perfect, and the internal pressure Even if the odor rises, the internal odor does not leak out.

[0009]

[Embodiment of the invention]

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. The container body (1) is a rectangular box with a bottom, and its side surface (8) is formed in a tapered shape whose diameter gradually increases from the bottom (7) toward the upper surface opening (4). An outer flange (2) is projected from the outer periphery of the upper surface opening (4) all around. An engagement projection (3) is protruded from the lower surface of the distal end of the outer flange (2). Also, a convex ridge (5) is provided on the upper surface opening (4) of the container body (1), that is, a contact surface with the lid (10), so as to protrude over the entire circumference, and a predetermined reinforcing portion is provided. A rib (6) is formed.

The lid (10) has a shallow dish shape, and a concave groove (14) having an open lower surface, into which the convex ridge (5) of the container body (1) fits, is formed on the periphery thereof. The packing (15) is disposed in the groove (14). Then, as shown in FIG. 6, a part of the outer peripheral edge (16) of the lid (10) is cut out, and the fitting engagement portion (11) that engages with the outer flange (2) in a fitting manner is flexible. The cutout (17) is formed through the sex base (12). The flexible base (12) is a thin-walled portion that can be easily bent.

[0011] The fitting engagement portion (11) includes an L-shaped portion (11a) formed as an entire L-shape, and a fitting-killing convex portion (11b) formed at the tip of the L-shaped portion (11a). ), And the L-shaped portion (11a) and the fitting-in protruding portion (11b) form a substantially U-shaped fitting groove (13). Since the container body (1) and the lid (10) are rectangular in shape, the fitting engagement portion (11) is provided at a total of four locations, that is, the central portion of the short side and the long side. Of course, it may be provided in more places.

Next, a method of using the disposal container (A) will be described. Fill the container body (1) with dirty syringes, bottles, bags, surgical gloves and any other medical waste. When full, the lid (10) is closed and the upper opening (4) of the container body (1) is closed. At this time, the convex ridge (5) formed on the contact surface of the container body (1) fits into the concave groove (14) of the lid (10), and the packing ( The tip is in close contact with 15).

In this state, the four engagement portions 11 provided on the long side and the short side of the lid 10 are bent at the base 12. The bent engagement portion (11) is folded inward, and the engagement projection (3) on the lower surface of the distal end of the outer flange (2) fits into the engagement groove (13), and is tight. The fitting engagement portion (11) holds the outer flange (2) at four locations, and is fixed in the fitted and killed state. As a result, it is possible to sufficiently cope with an increase in internal pressure due to putrefactive fermentation of the contents or rough handling during transportation, and the lid (10) does not fall off.

On the other hand, the convex ridge (5) fitted into the concave groove (14) of the lid (10) is in close contact with the packing (15) and closely fits the container body (1) and the lid (10). The property is perfect, and the internal odor does not leak out even if the internal pressure increases due to the rotting fermentation of the contents.

[0015]

[Effect of the invention]

 In the present invention, since the lid is fitted to the container body and fixed in a state of being killed, the lid is detached even if the contained waste is putrefactive and fermented and the internal pressure of the disposal container rises. There is no such thing, and the contents do not scatter outside. In addition, since the convex ridge of the container body fits into the groove and adheres tightly to the packing, the tight fit between the container body and the lid is perfect, and even if the internal pressure rises due to decay and fermentation of the contents, the internal pressure rises. No bad smell leaks out.
