DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soup container in which a lid is detachably fitted to a container body which is open at the top, and more particularly to a soup container such as hot soup, miso soup and other soup foods. The present invention relates to a soup container that is conveniently used for transportation.

[0002]

2. Description of the Related Art In the case of a school lunch, for example, soups and miso soup cooked at a lunch center are transported to each school while they are hot, and then divided into individual containers and transported to each classroom. .

If the container is open at the top, the contents are easily spilled by the rocking of the container during transportation. Therefore, there is a demand for a container that does not spill contents even when transporting a container containing soup food. Conventionally, as an example of a container for this purpose, a container having a configuration in which a lid b is detachably fitted to a container main body a with a screw type structure c as shown in FIG. 8 has been generally adopted.

A bowl is used as a container for storing noodles. When serving the bowl, a method of wrapping it with a film to prevent the juice from spilling has been adopted.

[0005]

However, in the case of the soup container having a configuration in which the screw-type lid is detachably fitted, the packing is mounted between the lid and the opening edge of the container. The contents (juice) are applied to the back side of the lid by the rocking during transport of the container, and at the time of this rocking, the air inside the container expands due to the hot contents, and the contents are expanded together with the expanded air by the internal pressure. However, there is a problem that the fluid leaks out through the screw fitting portion. In order to avoid this, it is sufficient to attach a thick packing as much as possible to the lid side, but because the packing is thick, the negative pressure acts strongly when the contents cools, and the lid opens. There was a problem that it became difficult.

Also, in the case of the wrapping method using the film, the contents may leak due to shaking during transportation. In particular, when the bowl is made of lacquer ware, the wrap is difficult to stick. After the white matter had entered, it became very difficult to stick, and it was peeled off by vibrations during transportation and the juice spilled.

In order to prevent the contents from spilling during transportation, a tapper type container having a structure in which a synthetic resin lid e is elastically fitted to the container body d as shown in FIG. 9 is used. I thought that. However, there is no problem if this tapper type container stores cold juice, but if it stores hot juice at around 70 ° C., for example, the inside air heats and expands after the lid is closed. As shown by the one-dot chain line, the lid e swells, and there is a problem that the stored juice leaks out together with the inflated air from the weakly fitted portion. In addition, when the contents are hot and the air expands extremely, there is a problem that the lid is thrown away.

[0008]

[Development background of the present invention] The present inventor solved a problem by opening a small hole in the cover of the lid in order to eliminate the phenomenon that the air inside the container expands due to hot contents (soup food) and the internal pressure increases. Tried to plan. As a result, the phenomenon in which the hole exerted the effect of degassing and the internal pressure in the container was increased could be eliminated, but on the other hand, when the contents oscillated when transporting the container,
A new problem arises in that the juice comes out of the hole together with the expanded air.

The present inventor has studied the effect of the contents (juice) in the container popping out of the hole of the lid when searching for means for solving the above problems, and has confirmed the following phenomena.

[0010] That is, when the container containing the soup food is transported and the container is shaken (usually swaying in the horizontal or oblique direction), a wave is formed on the liquid level g in the container, which is the inner surface of the surrounding container wall. Ripples are transmitted as ripples, collide, reflect and move to the inner surface on the other side. At this time, whether the container has a circular cross section or a rectangular cross section, ripples propagate similarly regardless of the form. On the way, waves in opposite directions collide with each other and are superimposed locally,
It is buffered and attenuated to small waves, but in any case,
The liquid level in the container is wavy. This wavy shape moves on the liquid surface, and the wave crest hits the hole of the lid. At the same time, the swinging of the hot juice (around 70 ° C.) rapidly heats and expands the air in the container, and a phenomenon occurs in which the attached juice jumps out of the hole together with the expanded air.

Therefore, the inventor of the present invention provided a means for forming a shield for preventing the wavy movement generated on the liquid surface of the soup contained in the container or for preventing the soup from being superimposed, and for damping the ripples. I thought about taking it around. Also, the present inventors have conceived of forming a vent hole at a position far from the liquid surface in the vertical direction. The present invention has been completed by further developing such an idea.

[0012]

In order to solve the above-mentioned problems, the present invention employs the following means. That is, the soup container according to the present invention is a soup container configured to removably fit a lid with respect to the container body that is open at the top,
The cover portion of the lid is provided with a tubular portion that is opened downward of the container body, and at least one vent hole is provided on the top surface of the tubular portion. .

In a preferred embodiment of the soup container according to the present invention, in a soup container in which a lid is detachably fitted into a container body having an open top, the cover of the lid is provided with a cover of the container body. It is characterized in that a cylindrical portion having an open lower end protruding downward is provided, and at least one vent hole is provided in a top surface portion of the cylindrical portion.

In another preferred embodiment, in a soup container configured to removably fit a lid into a container body that is open at the top, the cover part of the lid is depressed upward so that the container body is depressed. , A cylindrical portion opened downward is provided, and at least one vent hole is provided on the top surface of the cylindrical portion.

In another preferred embodiment, in a soup container in which a lid is detachably fitted to a container body which is open at the top, a cover portion of the lid is recessed upward, and a peripheral edge of the recess is formed. A cylindrical portion that is opened downward from the container body is provided by projecting a circumferential wall that is continuous in the circumferential direction downward, and at least one airbag is provided on the top surface of the cylindrical portion. It is characterized in that a hole is provided.

In the soup container having a cylindrical portion projecting downward, it is preferable that a lower end portion of the cylindrical portion is open outwardly in a conical shape.

In each of the soup containers, it is preferable that the inner surface of the cylindrical portion is formed smoothly. Further, a plurality of vent holes may be provided on the top surface of the cylindrical portion.

However, when using the soup container,
When the cylindrical portion provided on the cover portion of the lid projects downwardly of the container body, as shown in FIG. 2, the wavy generated on the liquid surface of the soup in the container body is formed on the cylindrical portion. It is possible to avoid the collision with the wave attenuated by the collision and the wave propagating from the opposite side. Therefore, despite the short distance between the liquid level and the top surface located at the top of the cylindrical portion, the liquid level in the cylindrical portion hardly or rarely rises. It is possible to prevent the contents (juice) from jumping out of the provided vent holes. As a result, even if the container shakes considerably, it is possible to prevent the contents (juice) from jumping out of the vent holes, and it is possible to only vent the expanded air caused by the hot contents.

In the case where the tubular portion provided on the cover of the lid is formed by recessing the cover upward, even if ripples caused by shaking of the container propagate on the liquid surface, Since a cylindrical portion is locally formed as a concave portion in the cover portion and the top surface portion is separated from the liquid surface, the contents (juice) do not jump out from the vent hole of the top surface portion. is there.

A cylindrical portion provided on the cover portion of the lid is formed by projecting a concave portion formed by denting the cover portion upward, and projecting downward at the peripheral edge of the concave portion so as to be continuous in the circumferential direction. When configured with the peripheral wall provided, the contents from the vent hole are formed by the corrugated buffering action of the downwardly projecting peripheral wall and the cooperative action of the concave part that is recessed upward away from the liquid surface. (Juice) can be effectively prevented from jumping out.

Further, since the lower end portion of the cylindrical portion is formed to open outwardly in a conical shape, the waves that collide with the cylindrical portion are guided by the outer surface of the conical shape and rise. Become. The descending component of the wave is guided by the conical outer surface and separates from the cylindrical portion. As a result of this, it is possible to minimize the intrusion of waves into the inside of the cylindrical portion.

[0022]

Embodiments of the present invention will be described below with reference to the drawings. First Embodiment In FIGS. 1 and 2, a soup container 1 according to the present invention is configured such that a lid 3 is removably fitted to a container main body 2 which is open at the top. For the fitting, a tapper type fitting structure in which a synthetic resin lid 3 is elastically fitted to the upper peripheral portion 5 of the container body 2 is adopted.

The cover 6 of the lid 3, that is, the container body 2
At the center of the portion covering the upper opening 7, a cylindrical portion 9 having an open lower end and protruding downward from the container body 2 is integrally formed, and a top surface portion 10 at the top of the cylindrical portion 9 is provided. , One vent hole 11 is provided.

The projecting length of the cylindrical portion 9 is, for example, 10 mm.
And the diameter of the vent hole 11 can be set to about 1 mm.

However, in the case of the soup container having such a structure, as shown in FIG. 2, a wave 8a generated on the liquid level 8 of the soup in the container body collides with the cylindrical portion 9, and is attenuated by the collision. At the same time, it is possible to avoid superposition with the wave propagating from the opposite side. Therefore, despite the short distance between the liquid level and the top surface located at the top of the cylindrical portion, the liquid surface in the cylindrical portion hardly rises and is provided on the top surface of the cylindrical portion. It is possible to prevent the contents (juice) from jumping out of the vent hole. As a result, even if the container shakes considerably, it is possible to prevent the contents (juice) from jumping out of the vent holes, and it is possible to only vent the expanded air caused by the hot contents.

[0026] Second Embodiment FIG. 3, the cylindrical portion 9 which projects downwardly in the cover portion 6 of the lid 3
The lower end portion 1 of the cylindrical portion 9 is shown.
2 is configured to open outward in a conical shape. However, the wave that collides with the cylindrical portion 9 is guided by the conical outer surface 13 and rises (a state indicated by a symbol A). Further, the descending component is guided by the conical outer surface 13 and separates from the cylindrical portion 9 (a state indicated by a symbol B). As a result of this, it is possible to minimize the intrusion of waves into the inside of the cylindrical portion. Further, by adopting such a structure in which the cylindrical portion 9 is open at the lower end, it becomes easy to clean the inside of the cylindrical portion.

Since it is difficult to integrally form such a specially shaped tubular portion with the lid, the tubular portion is attached by an appropriate bonding means. In the case of a resin in which an adhesive cannot be used, the resin may be attached by, for example, means of ultrasonic welding.

The other structure of the container according to this embodiment is the same as that of the first embodiment.

Third Embodiment FIG. 4 shows another embodiment of the soup container 1 according to the present invention, which differs from the first embodiment in the configuration of the cylindrical portion. Is similar. The tubular portion 9 is
As shown in FIGS. 4 and 5, the cover 6 of the lid 3 is concaved upward to form a cylindrical shape that is opened downward from the container body 2. Further, a single vent hole 11 is provided in the top surface portion 10 at the upper part of the cylindrical portion 9.

However, in the case of the soup container having such a configuration, even if ripples generated by shaking of the container propagate on the liquid surface, a cylindrical portion as a concave portion is locally formed in the cover portion, and Because the top surface is located away from the top surface, the contents (juice) do not jump out from the vent hole 11 on the top surface.

Fourth Embodiment FIG. 6 shows another embodiment of the soup container 1 according to the present invention. The configuration of the cylindrical portion is different from that of the first embodiment. Other configurations are the same.

As shown in FIGS. 6 and 7, the cylindrical portion 9 has the cover 6 of the lid 3 recessed upward, and the peripheral wall 16 continuous in the circumferential direction at the peripheral edge of the concave portion 15 is lowered. By projecting in the direction, the container body 2 is formed in a cylindrical shape opened downward to the container main body 2. In this case, for example, the depth of the concave portion 15 may be set to 2 to 5 mm. However, in the case of the soup container having such a configuration, the peripheral wall 16 protruding downward is used.
And the cooperative action of the concave portion 15 that is concave upward away from the liquid surface, it is possible to effectively prevent the contents (juice) from jumping out of the vent hole 11.

Other Embodiments In the present invention, the materials constituting the container body and the lid are not particularly limited. Also, its size is not specified,
It covers everything from large containers to small containers like bowls.

The present invention can be applied not only to the above-mentioned tapper type container but also to a container having a screw type lid. It is not necessary to form the packing thick as in the above.

In the present invention, the cylindrical portion is formed in a cylindrical shape as shown in FIG. 1 and also in a square cylindrical shape (polygonal cylindrical shape such as a triangular cylindrical shape, a square cylindrical shape, a hexagonal cylindrical shape). Good. or,
It may be configured as an elliptical tube or a conical tube whose diameter increases slightly downward.

In order to suppress the penetration of the wavy liquid, the cylindrical portion must have a long configuration (a configuration with a deep recess) if its diameter is large, but a relatively short length if its diameter is small. (Relatively shallow configuration of the recess)
It is possible to prevent the contents (juice) from jumping out of the vent hole. However, if the diameter is too small, there is a problem that cleaning becomes difficult. The inner surface of the cylindrical portion is preferably smooth from the viewpoint of cleaning. Also, the diameter of the vent hole is preferably about 1 mm in order to make the contents (solid matter such as protein) difficult to clog, but about 0.5 mm when the clogging of the contents is not considered. May be.

In the above embodiment, the cylindrical portion is provided at the center of the lid, but may be provided near the periphery of the lid. When the size of the container is large, the vent hole may be formed large or the number thereof may be increased.

[0038]

The present invention has the following excellent effects. According to the present invention, a cylindrical portion that is opened downward from the container main body is provided on a cover portion of a lid that is detachably fitted to the container main body, and at least one airbag is provided on a top surface portion that forms an upper portion of the cylindrical main portion. A configuration in which a hole is provided is adopted. Therefore, even when the container containing the hot juice is swung when being transported, only the expansion air caused by the hot contents can be evacuated by the action of the cylindrical portion, and the air from the bleed hole can be removed. The contents can be prevented from jumping out. Thereby, it is possible to prevent the contents (juice) from leaking from the screw fitting portion or the fitting portion in the closed state as in the related art. Further, it is possible to solve the above-described problem that it is difficult to open the screw cap by the action of the negative pressure due to the inflow of air from the vent hole.

In particular, in the case where the tubular portion is configured to protrude below the cover of the lid, the tubular portion directly blocks the propagation of ripples to attenuate the waves and superimposes the waves. Can be prevented. Therefore, despite the short distance between the top surface and the liquid surface, the liquid level in the cylindrical portion is hardly or little raised, and the contents from the vent hole provided on the top surface of the cylindrical portion are reduced. Can be prevented.

In the case where the cylindrical portion is formed by depressing the cover portion of the lid upward, when the ripple generated by the swing of the container propagates on the liquid surface, it is locally directed upward. Since the concave portion is formed in the concave portion, even if a part of the wave enters the concave portion, since the vent hole is located above the liquid surface, the contents from the vent hole are removed. Can prevent jumping out.

Further, when the cylindrical portion is constituted by a concave portion recessed above the cover portion of the lid and a peripheral wall protruding below the concave portion, the above-described direct buffering of the ripples by the peripheral wall protruding downward is provided. By cooperating with the concave portion which is recessed upward away from the liquid surface, it is possible to effectively prevent the contents (juice) from jumping out of the vent hole.

[0042] The soup container of the present invention is provided with a tubular portion that is opened downward from the container body on the cover of the lid,
It has the advantage that it is easy to manufacture because it adopts a simple structure in which a vent hole is provided on the top surface, and that the inside of the cylindrical part is easy to clean and clean because it has a downward open structure. There is.

In the soup container of the present invention, the lower end portion of the cylindrical portion has a structure that is opened conically outward, so that the waves that collide with the cylindrical portion are applied to the outer surface of the conical shape. You will be guided up. The descending component is guided by the conical outer surface and separates from the cylindrical portion. As a result of this, it is possible to minimize the intrusion of waves into the cylindrical portion. In addition, by adopting such a structure in which the cylindrical portion is open at the lower end, there is an advantage that the inside of the cylindrical portion can be easily cleaned.

In the present invention, when the inner surface of the cylindrical portion is formed to be smooth, the cleaning becomes easier. Providing a plurality of vent holes can accommodate a container having a large volume.
