Description

Medical waste sealed container and a mold for forming the same {Vessel for sealing pathogenic waste and mold for forming it}

The present invention relates to an airtight container for medical waste and a mold for molding the same, and more particularly, to an airtight container that can be contained and sealed to treat various pathogenic and infectious wastes generated in medical institutions, and a mold for molding the same.

Medical waste discharged from medical waste generating institutions such as hospitals includes extracts extracted from the patient's body, various drugs and injections used for treatment.

In principle, these wastes have a high risk of secondary infection, so they are collected, sealed, and handled under special management, and then all of them are incinerated.

In order to handle this, the above medical wastes were collected mainly using plastic bags to prevent leakage of liquids such as various drugs, injections, or extracts such as blood.

However, even if medical waste is collected by such a plastic bag, the exclusive sealed container is not completely sealed when transporting after placing the plastic bag in the exclusive sealed container, so there is still a risk of secondary infection or contamination due to leakage of waste to the outside. do.

Due to the above problems, in recent years, various types of airtight containers have been developed and suggested as in the prior art below for complete sealing of medical waste.

Specifically, "in the closed container for infectious waste provided with the lid 10 and the main body 20 and the lid 10 is hermetically coupled, the coupling piece 11 protrudes directly below the lower end of the periphery, but is cut at predetermined intervals A portion 12 is formed, divided into a plurality, and a coupling piece 11 having a coupling step 13 formed outside the lower end and a lid 10 having a coupling groove 14 on the inner side of the coupling piece 11 ), and an upper end coupled to the coupling groove 14, connected to a plurality of supports 22 on the upper outer side, and an insertion groove 23 for inserting and fixing the coupling piece 11, respectively. It consists of a main body 20 having 21 formed therein, and the cutout 12 of the lid 10 has a shorter incision than the width of the coupling piece 11 so that the coupling piece 12 can be continuously formed. And the support 22 of the main body 20 is formed at a position corresponding to the cutout 12 when the lid 10 is coupled to each other, and is a sealed container for infectious waste, characterized in that it can be fitted with each other." It is disclosed.

At this time, the lid closes the main body while the coupling step is caught on the fixed frame.Since the upper surface of the coupling step is horizontal and the lower surface of the corresponding fixed frame is also horizontal, the locking state may be released when an impact is applied horizontally from the outside. I can.

In other words, even if the conventional medical waste sealed container covers the lid and completely seals it, the lid may be opened due to an external shock applied during handling such as transport, transport, or the carelessness of an operator. Due to this, there is always a risk that some of the waste inside the container could leak.

Accordingly, the present invention is to solve the above problems, and an object of the present invention is to provide a medical waste sealed container having a structure in which the closed container lid is never opened even when an external shock or forced opening is attempted, and a mold for molding the same. will be.

The medical waste sealed container according to the present invention for achieving the above object includes a container-shaped housing for accommodating medical waste therein, a horizontal sleeve extending along the upper and outer sides of the housing, and an edge of the horizontal sleeve. A vertical sleeve extending vertically along the top and having a locking step protruding inwardly is formed, and an insertion piece inserted into the interior of the housing along the edge by covering and sealing the housing and extending to the horizontal sleeve outside the insertion piece And a lid formed of a locking piece that is formed and a locking piece that is bent in a'U' shape from the locking piece and is caught by the locking step, and a sealing member that is inserted between the insertion piece and the locking piece to seal the upper end of the housing. In the sealed container for medical waste, a wedge surface formed to be inclined downward inward may be formed on a lower surface of the locking step and an upper surface of the locking piece.

Here, it is preferable that ribs having a protruding shape are formed at regular intervals to prevent the locking piece from contacting the upper outer circumferential surface of the housing.

In addition, it is preferable that a plurality of locking steps are formed along the vertical sleeve at predetermined intervals.

In addition, the lower surface of the locking piece may be in close contact with the upper surface of the horizontal sleeve to seal a space formed between the housing and the locking piece.

In addition, in the horizontal sleeve, a mold hole may be formed at each position corresponding to each of the locking step so that the mold for forming the locking step may move forward or backward.

A mold for forming an airtight container for medical waste according to another embodiment of the present invention includes a container-shaped housing for accommodating medical waste therein, a horizontal sleeve extending along the upper and outer sides of the housing, and the horizontal sleeve. A mold for molding a container body comprising a vertical sleeve extending vertically along an edge and having a locking step protruding inwardly at an upper end, comprising: a first mold for molding the housing and a second mold for molding the horizontal sleeve An upper mold comprising a mold and a third mold for forming the vertical sleeve; And a fourth mold for molding the housing and the horizontal sleeve by combining the first and second molds, a fifth mold for molding the locking step by combining the second and third molds, and the third. Consisting of; a lower mold including a sixth mold that is combined with a mold to form the vertical sleeve, wherein an inclined downwardly inclined inward is formed at the upper end of the fifth mold so that the lower surface of the locking step is inwardly It can be formed to be inclined downward.

In addition, it is preferable that a recessed rib portion is further formed on the inner side of the second mold.

According to the present invention described above, the locking piece does not deviate beyond the locking step by the wedges formed on the top of the locking step and the locking step, so that the lid is never opened even when an external shock or a forced opening is attempted, so there is an advantage of being surely sealed. .

In addition, since the ribs are formed, the locking piece is not pushed toward the housing, so the position of the sealing member is accurately maintained, so the sealing effect is very excellent.

In addition, since a plurality of locking steps are formed on the side of the container body rather than the lid, the structure of the lid is simple and simplified, so that molding is easy, and the strength of the lid is improved.

Hereinafter, an embodiment according to the present invention will be described in more detail with reference to the accompanying drawings.

For reference, the description with reference to the drawings is for easier understanding of the present invention, and the scope of the present invention is not limited thereto. Further, in describing the present invention, if it is determined that a detailed description of related known technologies may unnecessarily obscure the subject matter of the present invention, a detailed description will be omitted.

Figure 2 is a perspective view showing the appearance of the medical waste sealed container according to an embodiment of the present invention, Figure 3 is a perspective view showing the container body of the present invention shown in Figure 2, Figure 4 is the present invention shown in Figure 2 It is a perspective view showing the lid of.

The present invention can be largely composed of a container body 100 and a lid 200 that covers and seals the container body 100.

First, the container body 100 is a container capable of holding medical waste, as shown, a horizontal sleeve 120 and a vertical sleeve 130 formed along the upper outer edge of the housing 110 and the housing 110. It can be composed of.

The housing 110 has a container shape with an open top so that waste can be contained therein, and the material may be made of synthetic resin.

For reference, the housing 110 may be formed in various ways, such as a cylindrical shape or a rectangular cylindrical shape, and an example of the present invention will be described based on a cylindrical shape.

In addition, a horizontal sleeve 120 is formed outside the upper end of the housing 110.

The horizontal sleeve 120 is continuously formed along the outer circumference of the housing 110 and has a structure extending outward.

Here, it is preferable that the horizontal sleeve 120 is formed at a lower side by a predetermined height from the upper end of the housing 110. This is to form a space in which the edge of the lid 200 can be inserted together with the vertical sleeve 130.

At this time, it is preferable that the mold hole 121 is formed on the horizontal sleeve 120.

As will be described later, the mold hole 121 is a hole formed due to a space through which a mold for forming the inclined locking step 131 can be inserted or removed when the horizontal sleeve 120 is formed.

A plurality of the mold holes 121 are formed at regular intervals as shown in FIG. 3.

In addition, the vertical sleeve 130 is formed to extend continuously along the edge of the horizontal sleeve 120 and is formed at a right angle to the vertical sleeve 130.

Accordingly, the upper end of the housing 110, the horizontal sleeve 120 and the vertical sleeve 130 have a cross-section of approximately the same shape as'┗┛', and the locking piece 220 of the lid 200 to be described later. Can be pulled in.

Importantly, a locking step 131 is formed on the upper end of the vertical sleeve 130.

5 shows a cross-sectional perspective view of the main part of the present invention shown in FIG. 2.

The locking step 131 has a function of locking the lid 200 so that it is not opened or closed, and is formed to protrude from the inner side of the vertical sleeve 130 toward the inside.

Here, the lower surface of the locking step 131 may be formed horizontally, but preferably an inclined wedge surface 132 is formed. In other words, the wedge surface 132 is formed to be inclined downward inward.

In addition, the vertical sleeve 130 is continuously formed along the edge of the housing 110 together with the vertical sleeve 130, but a plurality of the locking step 131 is spaced apart from the vertical sleeve 130. It is preferable to be provided. For reference, the mold hole 121 is formed at a position corresponding to the lower side of each of the locking step 131.

Preferably, the guide surface is formed to be inclined inwardly on the upper surface of the locking step 131 so that the locking piece 230 of the lid 200 is guided to be inserted while sliding.

Next, the lid will be described with reference to FIG. 6. 6 is an enlarged cross-sectional view of a main part of the present invention shown in FIG. 2.

The lid 200 covers and seals the housing 110 and is formed in a flat plate shape and has a shape corresponding to the cross-sectional area of the open upper portion of the housing 110.

An insertion piece 210, a locking piece 220, and a locking piece 230 are continuously formed along the edge of the lid 200.

First, the insertion piece 210 protrudes downward along the edge of the lid 200 and is inserted into the housing 110.

At this time, a radius from the center of the lid 200 to the outer surface of the insertion piece 210 is similar to or slightly shorter than the inner radius of the housing 110 so that the insertion piece 210 is It would be good to make it in close contact with the inner circumferential surface of the housing 110 while being inserted into it.

A reinforcing member 240 is formed between the insertion piece 210 and the lid at regular intervals to reinforce the rigidity of the lid 200.

And the locking piece 220 is formed to extend downwardly through the upper end of the housing 110 from the outside of the insertion piece 210, the housing 110, the horizontal sleeve 120, and the vertical sleeve 130 It extends to the formed space.

At this time, a point where the insertion piece 210 and the locking piece 220 meet is positioned at the upper end of the housing 110, and a sealing member 300 to be described later may be inserted and installed.

The locking piece 220 has elasticity so as to maintain a certain distance from the insertion piece 210, but is bent toward the insertion piece 210 by an external force, and can be restored to its original state when the external force is removed.

Meanwhile, a locking piece 230 is formed at an end of the locking piece 220.

The locking piece 230 has a structure capable of being hooked on the locking step 131 described above, and is extended from the locking piece 220, and is formed upward by being bent in a'U' shape.

Here, the upper surface of the locking piece 230 has a shape corresponding to the lower surface of the locking step 131 so as to be caught by the locking step 131. That is, an inclined wedge surface 132 is also formed on the upper surface of the locking piece 230.

At this time, the wedge surface 132 of the locking piece 230 is formed to be inclined upwardly to the outside. In other words, it slopes downward inward.

Importantly, it is preferable that the length from the center of the lid 200 to the outer end of the locking piece 230 is equal to or longer than the length from the center of the housing 110 to the locking step 131 Do.

Therefore, when the locking piece 230 is inserted into the locking step 131, the locking piece 220 has an elastic force to be spread outward, so that the locking piece 230 is inside the vertical sleeve 130. Since the side is pressed and at the same time, the wedge surface 132 of the locking piece 230 cannot cross over the wedge surface 132 of the locking step 131, the lid 200 is never opened.

Next, the sealing member 300 is inserted between the insertion piece 210 and the locking piece 220 and is in close contact with the upper end of the housing 110 to prevent the waste inside the housing 110 from leaking.

The sealing member 300 may have a ring shape and may be made of an elastic material such as rubber or silicone.

The sealing member 300 may be assembled in a ring shape by a fitting method between the insertion piece 210 and the locking piece 220, but may be formed by injecting and solidifying a liquid material.

It is important in the present invention that a plurality of ribs 140 are formed at regular intervals on the upper outer circumferential surface of the housing 110.

The rib 140 may protrude from the outer circumferential surface of the housing 110 and may be elongated vertically.

In this case, the rib 140 prevents the locking piece 220 from contacting the upper outer circumferential surface of the housing 110.

When the lid 200 is pressed to close, the sealing member 300 is compressed, and the locking piece 230 descends along the inclined surface of the locking step 131 and is caught on the wedge surface 132.

Here, the locking piece 230 is forcibly closed inward, so that the locking piece 220 comes into contact while pushing toward the housing 110.

If the rib 140 does not exist, when the locking piece 220 approaches the housing 110, the sealing member 300, which was accurately positioned at the top of the housing 110, is pushed inward and centering ( centering) is wrong. This causes a decrease in the sealing effect.

Therefore, since the ribs 140 are formed to prevent access to the locking piece 220, the sealing member 300 can be compressed at an accurate position to perform sealing completely.

Hereinafter, another embodiment of the present invention will be described. 7 is an enlarged cross-sectional view of a medical waste sealed container according to another example of the present invention.

For this, referring to the bar shown in FIG. 7, the length of the locking piece 220 is extended so that the lower surface of the locking piece 230 is in close contact with the upper surface of the horizontal sleeve 120.

In addition, the width of the mold hole 121 formed in the horizontal sleeve 120 is narrowed so that the mold hole 121 is not positioned directly below the lower surface of the locking piece 230.

When this structure is made, the space (s) formed between the upper outer circumferential surface of the housing 110 and the locking piece 220 and the horizontal sleeve 120 is sealed, so sometimes waste due to defects in the sealing member 300 Even if a part of the material leaks, leakage to the outside can be blocked or minimized.
