Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a transport container, and more particularly, to a transport container suitable for storing wastes and the like used for medical purposes.
[0002]
[Prior art]
Conventionally, articles used for medical purposes, such as injection needles, absorbent cotton, catheters, etc., are stored in dedicated containers with high airtightness and transported to a predetermined place.
As shown in FIGS. 6 and 7, the sealed container for storing or transporting the article so that the article is not exposed to the outside is slightly lower than the flange 3 on the ceiling of the opening 2 of the container body 4. Folding ribs 10 having a substantially inverted L-shaped cross section are respectively formed at the positions, and a substantially dish-shaped lid body 28 is mounted from above so as to straddle the flange 3.
[0003]
In such a dedicated container, the seal member 25 is interposed between the container main body 4 and the lid body 28, and when the lid body 28 is covered, the undercut portion 30 is elastically deformed and is formed on the lower surface of the flange 3. Since it is locked, the lid body 28 is structured so that it cannot be easily removed, and is substantially sealed.
Such a container for transportation is usually transported as it is, once discarded, or discarded or incinerated.
[0004]
[Problems to be solved by the invention]
By the way, in such a transport container, the lid 28 is closely fitted to the container body 4 as described above in order to improve the sealing degree of the container body 4. For this reason, the attaching work of the lid body 28 requires a comparatively strong force, and there is a problem that it is difficult for a woman with weak force to work.
[0005]
In particular, in the case of the substantially rectangular container body 4, the opening end portion having a U-shaped cross section formed on the lid body 28 intersects at an angle close to a substantially right angle at the four corners. There was no escape, and the installation work was more difficult.
The present invention has been made in view of such circumstances, and an object of the present invention is to provide a transport container that can be easily attached to a container body and that can ensure sufficient sealing performance.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the transport container according to the present invention comprises:
In the opening 2 of the container body 4 whose one side is open, it has a flange 3 surrounding the opening 2, and has a folded rib 10 in a position substantially parallel to the flange 3 and slightly lowered,
When the opening end portion 5 having a substantially U-shaped cross section of the lid body 28 is mounted so as to straddle the flange 3 of the container body 4, the undercut portion 30 of the lid body 28 is locked to the flange 3. A transport container made of synthetic resin,
A slit-like notch 32 is provided at the opening edge of the lid 28, and a pair of recesses 33, 33 are provided in such a manner as to sandwich the slit-like notch 32. The fitting between the container body 4 and the lid body 28 is maintained by detachably passing a trifurcated lock member 50 between the opening edge 10a of the rib 10. .
[0007]
According to the present invention having such a configuration, since the slit-shaped notch is provided at the opening edge of the lid, a force for deforming the lid when fitted can be absorbed by the notch. . Moreover, if the notch is formed, the lid body can be easily detached, but can be locked by the lock member, so that the lid body can be prevented from coming off.
[0008]
Further, the trifurcated locking member used in the transport container of the present invention has a pair of horizontal blades 51, 51 and a central blade 52 that hangs downward from the approximate center of the pair of horizontal blades 51, 51. The horizontal wings 51, 51 and the central wing 52 are characterized in that fitting pieces 7 each having a substantially U-shaped cross section are formed at the tip portions thereof.
Such a lock member for a transport container can be manufactured at a relatively low cost, and the workability is easy.
[0009]
Furthermore, the transport container according to the present invention is:
The opening 2 of the substantially rectangular tube-shaped container body 4 whose one surface is open has a flange 3 that surrounds the opening 2, and a folded rib 10 that is substantially parallel to the flange 3 and slightly down. ,
When the opening end portion 5 having a substantially U-shaped cross section of the lid body 28 is mounted so as to straddle the flange 3 of the container body 4, the undercut portion 30 of the lid body 28 is locked to the flange 3. A transport container made of synthetic resin,
A slit-shaped notch 32 is provided at the opening edge of the lid 28, and a pair of recesses 33, 33 are provided in a manner sandwiching the slit-shaped notch 32,
Further, when the flange 3 at the opening edge of the container body 4 is provided with a pair of protrusions 35 , 35 that fit into the pair of recesses 33 , 33 without a gap , and the lid 28 is put on the container body 4 In addition, the protrusions 35 and 35 are disposed in the recesses 33 and 33 to constitute a lock mechanism that holds the fitting between the container body 4 and the lid 28. It is said.
[0010]
If it is such a structure, the locking member used as another member will become unnecessary.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows a container body of a transport container according to one embodiment of the present invention, and FIG. 2 shows a lid, respectively. The same elements as those in FIGS. 6 and 7 of the conventional example are indicated by the same reference numerals.
[0012]
The container body 4 of this transporting container is formed of a bottom wall 31 and four side walls 37, 34, 35, 36 and is formed in a substantially rectangular tube shape with one surface opened, and is integrally formed of a synthetic resin such as polypropylene. ing.
In the opening 2 of the container body 4, a flange 3 and a folded rib 10 having a substantially inverted L-shaped cross section are formed at a position slightly lower than the flange 3 so as to surround the whole.
[0013]
On the other hand, the lid body 28 is formed in a substantially dish shape. In addition, slit-shaped notches 32 are formed at the four corners of the lid 28, and a pair of recesses 33, 33 are formed on both sides so as to sandwich the notch 32. Note that the recess 33 is formed in a tapered shape so that the width is slightly wider as it is closer to the opening end.
On the other hand, in this embodiment, a trifurcated lock member 50 as shown in FIG. 4 is prepared as another member.
[0014]
The lock member 50 is made of an elastically deformable synthetic resin, and is formed in a trifurcated shape by a pair of horizontal wings 51, 51 and a central wing 52 extending downward from the central portion. 51 and the central wing 52 are provided with fitting pieces 7 each having a substantially U-shaped cross section.
Below, the assembly | attachment when the lid | cover 28 formed as mentioned above is fitted to the container main body 4, and it hold | maintains with the lock member 50 is demonstrated.
[0015]
First, as shown in FIG. 3, the lid body 28 is disposed above the opening 2 of the container body 4. Thereafter, the opening end 5 having a substantially U-shaped cross section formed at the opening edge of the lid 28 is pushed down toward the flange 3 of the lid 28. If the lid body 28 is strongly pressed down in this order toward the outer peripheral edge in this way, as shown in FIG. 4, the undercut portion 30 of the lid body 28 gets over the flange 3 and the lid body 28 and the container main body 4. Are engaged with each other.
[0016]
Here, when the lid 28 is pushed in strongly, there has been no place for force to escape when the lid 28 and the container body 4 are engaged, so a large force is required particularly at the final part of the fitting. However, according to the present embodiment, since the slit-shaped notches 32 are formed at the four corners of the lid body 28, it is possible to diverge the force accompanying the deformation through these notches 32. . Therefore, the lid 28 can be put on the flange 3 of the container main body 4 in the final portion, regardless of which corner portion is fitted.
[0017]
When the fitting between the lid body 28 and the container body 4 is completed in this way, the locking member 50 prepared as a separate member is fitted between the pair of recesses 33 formed on the lid body 33 and the fitting piece 7 of the horizontal blade 51. And the fitting piece 7 of the vertical blade 52 may be fitted to the opening edge 10a of the folded rib 10.
In this way, if the separate lock member 50 is mounted between the container body 4 and the lid body 28, the sealed container can be maintained in a more tightly sealed state.
[0018]
As mentioned above, although one Example of this invention was described, this invention is not limited to the said Example at all.
For example, in the above-described embodiment, a rectangular tube-shaped container having one side opened has been described, but the present invention can also be applied to a cylindrical container.
Furthermore, the lid body 28 and the container body 4 can be assembled without using the lock member 50 as a separate member.
[0019]
FIG. 5 shows another embodiment in which the lock member 50 which is a separate member is not used.
In this embodiment, the lid 28 is similar to the above embodiment in that a slit-shaped notch 32 and a pair of recesses 33, 33 are formed on both sides thereof, as in the above embodiment. . Further, the recess 33 is formed in a taper shape having a larger inclination than the recess 33 shown in FIG.
[0020]
A difference of the embodiment shown in FIG. 5 from the above-described embodiment is that a pair of protrusions 35, 35 are formed at positions corresponding to the recesses 33, 33 of the lid 28 in the flange 3 of the container body 4. It is a point. The width A1 of the protrusion 35 and the width A2 on the proximal end side of the tapered recess 33 are such that A1 fits into A2 without a gap.
[0021]
When the lid body 28 is attached to the container body 4 on which the projections 35 and 35 are formed, the projection 35 on the main body side is recessed from the relatively large opening end 33 a in the recess 33 of the lid body 28. Since the projection 35 fits into the top surface 33b of the recess 33 formed in substantially the same dimension without gaps, the lid body 28 is guided inwardly along the tapered slope. And the container body 4 are firmly engaged. Accordingly, there is no possibility of causing a positional shift in the horizontal direction.
[0022]
【The invention's effect】
As described above, according to the transport container according to the present invention, since the slit-shaped notch is provided at the opening edge of the lid, the deformed force of the lid is caused by this notch when fitting. Can be absorbed. Further, if the cutout is formed, the lid body is easily detached, but the lid body can be prevented from coming off by mounting the lock member.
[0023]
Also, if a structure in which a protrusion on the container body side, there is no need to prepare a locking member separately. Furthermore, by forming the recess of the lid into which the protrusion is inserted into a tapered shape in advance, the protrusion can be easily inserted, and after the protrusion is completely inserted into the recess, the width Since the protrusion is held between the narrowed portions, the horizontal displacement can be prevented without moving in the width direction.
