TECHNICAL FIELD OF THE INVENTION
The present invention relates to a container having a handle.
[0002]
[Background Art]
2. Description of the Related Art Conventionally, a container having a flat circular container body and a lid member has been used as a container for shipping food such as miso.
[0003]
[Problems to be solved by the invention]
Such a container has a problem that it is inconvenient to carry when the filling amount is large. Therefore, it is conceivable to provide an engaging portion on the container body, attach a handle portion to the engaging portion, and form a container with a handle portion. However, when the handle is attached in this manner, a large load is applied to the engagement portion between the handle and the container body, and there is a problem that the handle is easily detached from the container body.
Further, when the filling of the container body is heavy, such as miso, the container body is inclined depending on the mounting method and the mounting position of the handle portion, and there is a problem that it is difficult to carry.
Further, the provision of the handle portion increases the number of members, which causes a problem that the assembly of the container becomes complicated.
[0004]
An object of the present invention is to provide a container in which the handle portion is not easily detached even when the filling amount is large, can be carried in a well-balanced manner, and requires no labor for assembly.
[0005]
[Means for Solving the Problems]
Therefore, the present invention seeks to achieve the above object by employing the following configuration.
Specifically, the container of the present invention has a bottom surface and a side surface formed so as to surround the bottom surface, and a container provided with a synthetic resin container main body having an opening at a surface facing the bottom surface. Along the periphery of the opening, a handle portion is provided rotatably with respect to the container body, and both ends of the handle portion are located at the center of the plane of the opening on the side surface of the container body. It is characterized by being integrally formed at a position facing and sandwiching the same.
Here, as the synthetic resin, polypropylene, polyethylene, polystyrene, polycarbonate, ABS resin and the like can be used.
[0006]
In the present invention having this configuration, the handle portion is integrally formed on the side surface of the container body, and since there is no engaging portion between the handle portion and the container body, the handle portion may come off when a large load is applied. Can be prevented.
In addition, when only one end is integrally formed with the side surface of the container body and a handle portion extending outward from the side surface of the container body is provided, it is difficult to balance when the weight of the filling in the container body is heavy. And it is difficult to carry. On the other hand, in the present invention, since both ends of the handle are integrally formed at positions opposed to each other across the plane center of the opening on the side surface of the container body, the container can be lifted with good balance, It can be easy.
Further, since the handle portion is formed integrally with the container body, even if the handle portion is provided, the number of members does not increase, and no labor is required for assembling the container.
[0007]
In this case, it is preferable that thin portions depressed in the rotation direction of the handle when the handle is gripped are formed near both ends of the handle.
By forming such a thin portion, the thin portion functions as a hinge, and it is possible to prevent the handle portion from breaking when the handle portion is gripped.
In addition, if the thin portion is not formed, it is difficult to always bend the handle at the same position, and if it is bent at a portion other than the predetermined position, it may be difficult to carry the container body in a well-balanced manner. There is. On the other hand, by forming the thin portion, the handle portion can always be bent at a predetermined position, and the container body can always be carried in a well-balanced manner.
[0008]
Further, it is preferable that the container body and the handle are made of polypropylene resin.
It is particularly preferable to use homopolypropylene or block polypropylene as the polypropylene.
The rigidity and strength of the container body can be ensured by making the container body made of a polypropylene resin. Further, the polypropylene-based resin has high recyclability, and the used container body and handle portion are collected and formed into pellets, so that the raw material of the container body and the like can be used again, and environmental protection can be achieved.
Further, by forming the handle portion with a polypropylene-based resin, excellent hinge characteristics can be exhibited, and even if a bending force acts on the point of action, there is little possibility of cracking at the point of action.
[0009]
The lid further includes a top plate for closing the opening of the container body and a lid member having a wall extending from an outer peripheral edge of the top plate. The container main body has a flange portion formed along the periphery of the opening, and the flange portion has a concave portion with which the nail of the lid material engages. Is preferably formed.
In this manner, the lid is provided with the claws, and the concave portion in which the claws of the lid are engaged is formed in the flange portion of the container main body, whereby the lid can be securely attached to the container main body.
[0010]
In this case, it is preferable that the plurality of claws are formed intermittently along the circumferential direction of the wall, and the concave portion of the container body is formed at a position corresponding to the claws.
The claws may be formed all around the inner side of the wall of the lid in the extending direction, but in this case, there is a problem that it is difficult to attach and detach the lid.
On the other hand, in the present invention, since the claws are provided intermittently, the attachment and detachment of the lid material can be easily performed. Further, since the concave portion is formed at a position corresponding to the claw of the lid member and is not formed over the entire circumference of the flange portion, the strength of the flange portion can be secured.
[0011]
At this time, the container body is a flat rectangular shape, the handle of the container body is located on the bottom side with respect to the opening, the bottom surface of the container body is formed smaller than the opening, It is preferable that the container body is formed so as to be housed in an opening of another container body.
[0012]
When the container main body has a flat rectangular shape, the area required for arrangement can be reduced as compared with the case where the container main body has a flat circular shape.
Further, by forming the container main body so as to be housed in another container main body, the container main bodies can be stacked. Therefore, the storage space can be reduced.
Further, since the handle is located on the bottom surface side of the opening of the container body, the handle does not obstruct the container body when the container body is overlapped with another container body.
[0013]
At this time, a holding portion for connecting the vicinity of both ends of the handle portion and the side surface and holding the handle portion is provided on a side surface of the container body, and the holding portion includes the holding portion, It is preferable that a notch is formed to separate the handle and the handle so that the handle can rotate.
[0014]
In the case where the holding portion is not provided, if the strength of both ends of the handle portion is reduced, the handle portion will hang down. In this case, when empty container bodies are stacked, there is a problem in that the hanging handle portion is in the way and the stacking property is deteriorated. Further, when containers are transported in a cardboard case, a gap is formed between adjacent containers due to the hanging handle portion, which may cause damage due to collision between the containers, deformation of the cardboard, and the like.
On the other hand, in the present invention, such a problem does not occur because the holding portion is formed so that the handle portion can be held at a predetermined position and the handle portion can be prevented from sagging.
Further, since the cut portion is formed in the holding portion, the handle portion and the holding portion can be easily separated by the force for lifting the handle portion, and the handle portion can be freely rotated.

Four claws 321 are provided, and are intermittently arranged at positions opposing each other with the plane center of the top plate 31 interposed therebetween.
[0025]
Therefore, according to the present embodiment, the following effects can be obtained.
(1) Since the handles 4A and 4B are integrally formed with the flange 25 of the container body 2 and there is no engaging portion between the container body 2 and the handles 4A and 4B, when a large load is applied, It is possible to prevent the handle parts 4A, 4B from coming off the container body 2.
[0026]
(2) When only one end is integrally formed with the side surface 22 of the container body 2 and a handle portion extending outward from the side surface 22 of the container body 2 is provided, the weight of the filling in the container body 2 is heavy. This makes it difficult to balance and difficult to carry.
On the other hand, in the present embodiment, both ends of the handle portions 4A and 4B are integrally formed at positions opposed to each other across the center of the plane of the opening 24 of the flange portion 25 of the container body 2, so that the container is well-balanced. 1 can be lifted and made easy to carry.
[0027]
(3) Since the handles 4A, 4B are integrally formed with the container body 2, even if the handles 4A, 4B are provided, the number of members does not increase, and the assembly of the container 1 does not require labor.
[0028]
(4) Further, since the two handle portions 4A and 4B arranged opposite to each other are provided, the container 1 can be transported in a more balanced manner than when only one handle portion is provided.
[0029]
(5) Since the thin portions 411 are formed in the handle portion main bodies 41A and 41B of the handle portions 4A and 4B, the thin portions 411 function as hinges, and when the handle portions 4A and 4B are gripped, the handle portions 4A and 4B are moved. Breaking can be prevented. In particular, in the present embodiment, since the thin portion 411 is formed so as to draw an arc, it is possible to more effectively prevent the handle portions 4A and 4B from cracking.
[0030]
(6) When the thin portion 411 is not formed, it is difficult to always bend the handle at the same position, and when the handle is bent at a portion other than the predetermined position, it is possible to carry the container body in a well-balanced manner. Can be difficult. On the other hand, by forming the thin portion 411, the handle body 41A, 41B can always be bent at a predetermined position, so that the container body 2 can always be carried in a well-balanced manner.
[0031]
(7) Since the handles 4A and 4B are formed of a polypropylene resin, they can exhibit excellent hinge characteristics, and are less likely to be broken at the action point even when the bending force acts on the action point. .
[0032]
(8) Since the container body 2 and the lid 3 are made of polypropylene resin, rigidity and strength can be secured. Above all, homopolypropylene and block polypropylene are used as the polypropylene, and the rigidity of the container body 2 and the lid member 3 can be made higher than in the case of using random polypropylene.
Further, since a polypropylene-based resin having a specific gravity of about 0.91 is used, the weight of the container 1 can be reduced.
Furthermore, the polypropylene resin is highly recyclable, and the used container body 2 and lid material 3 are collected and formed into pellets, which can be used again as a raw material for the container body 2 and the like, so that environmental protection can be achieved. Can be.
[0033]
(9) Since the claw 321 that engages with the concave portion 253 of the container body 2 is provided on the cover member 3, the cover member 3 can be securely attached to the container body 2.
[0034]
(10) If the claws are provided over the entire circumference of the lid 3, there is a problem that it is difficult to attach and detach the lid 3, but in the present embodiment, the claws 321 are provided intermittently. Therefore, the attachment / detachment of the lid member 3 can be easily performed.
Further, since the concave portion 253 is also formed in accordance with the position of the claw 321, the strength of the flange portion 25 can be secured as compared with a case where the concave portion is provided over the entire periphery of the flange portion 25.
[0035]
(11) Since the container 1 has a flat rectangular shape, it does not take up much space when arranged, and is excellent in storage and the like, as compared with a case of forming a flat circular shape.
[0036]
(12) Since the lid 3 is provided with the grip 313, the lid 3 can be removed with the grip 313, so that the lid 3 can be easily removed. Further, since a groove is formed in the grip portion 313 along the circumferential direction, the grip portion 313 can be firmly gripped.
[0037]
(13) The cover member 3 is formed with a concave groove 311. When the container 1 is stacked in the concave groove 311, the protruding portion 213 of the upper container body 2 is inserted. The stability at the time of doing can be improved.
[0038]
(14) Further, the container body 2 can be stacked by making the bottom surface 21 of the container body 2 smaller than the opening 24 so that the container body 2 can be stored in another container body 2. Therefore, the storage space can be reduced.
Further, since the handles 4A, 4B are located closer to the bottom surface 21 than the opening 24 of the container main body 2, when the container main body 2 is overlapped with another container main body 2, the handles 4A, 4B are obstructed. It will not be.
[0039]
(15) When the holding portion 222 is not provided, if the strength of both ends of the handle portions 4A, 4B is reduced, the handle portions 4A, 4B hang down. In this case, when the empty container bodies 2 are stacked, there is a problem that the hanging handle portions 4A and 4B are in the way and the stacking property is deteriorated. When the container 1 is transported in a cardboard case, a gap is formed between the adjacent containers 1 due to the hanging handles 4A and 4B, so that damage due to collision between the containers 1 and deformation of the cardboard can be prevented. There is a risk of inviting.
On the other hand, in the present embodiment, the holding portion 222 is formed so that the handle portions 4A and 4B can be held at the predetermined positions, so that the stacking property is deteriorated, and the damage due to the collision between the containers 1 during transportation or the like. And deformation of the cardboard can be prevented.
Further, since the notch portion 223 is formed in the holding portion 222, the handle portions 4A, 4B and the holding portion 222 can be easily separated by the force for lifting the handle portions 4A, 4B, and the handle portion 4A , 4B can be made rotatable.
[0040]
It should be noted that the present invention is not limited to the above-described embodiment, but includes modifications and improvements as long as the object of the present invention can be achieved.
For example, both ends of the handle portions 4A and 4B may be integrally formed on the side surface 22 of the container body, and may be integrally formed in a shape as shown in FIG. In this case, the surfaces of the handle portions 4A and 4B on the opening 24 side at both ends are located closer to the opening 24 than the surfaces of the handle portion main bodies 41A and 41B on the opening 24 side. When the 41A, 41B is rotated, the handle body 41A, 41B and both end portions will collide. Therefore, the handle main bodies 41A and 41B do not rotate too much.
Further, as shown in FIG. 5, the holding portion 222 may not be formed. If the holding part 222 is not formed, the manufacture of the container 1 becomes easy.
Further, as shown in FIG. 5, the holes 253 need not be formed. In this case, when the extension of the wall portion 32 of the lid member 3 is lengthened and attached to the container body 2, the end of the wall portion 32 in the extension direction extends to the end of the hanging portion 252 in the extension direction. The hook 321 may be brought into contact with the hook 321 and the hanging portion 252 of the flange 25.
By not forming the hole 253 in this manner, the manufacture of the container body 2 can be facilitated.
[0041]
In the above embodiment, the container body 2 and the lid member 3 are made of a polypropylene resin, but other synthetic resins may be used. Other synthetic resins include, for example, polypropylene, polyethylene, polystyrene, polycarbonate, ABS resin and the like.
Further, in the above-described embodiment, the bottom surface 21 of the container body 2 is formed smaller than the opening 24, and the container body 2 can be stored in another container body 2, but a sufficient storage space is secured. In such a case, the bottom surface 21 and the opening 24 may have substantially the same size and size so that the container body cannot be housed in another container body.
[0042]
Moreover, in the said embodiment, although the food etc. were filled in the container main body 2 of the container 1, the filling is not restricted to this.
Further, the lid 3 has four claws 321 intermittently arranged, but the present invention is not limited to this, and claws may be provided over the entire circumference of the lid 3. This makes it possible to improve the sealing performance of the container 1.
Further, when the container body 2 is filled with a material that does not require a sealing property, the lid member may not have the claws 321. By doing so, the production of the lid material can be facilitated.
Further, the container may not have a lid.
[0043]
