Description

  The present invention relates to a food container.

  Many different food containers for storing food are provided. As one of them, a natto container for containing natto is known. As a conventional natto container, a partition film is arranged on natto in the container, and a container (see Patent Document 1) in which a sachet in which a seasoning is sealed is placed on this film, or on the upper surface of the lid There is known a container (Patent Document 2) in which a storage recess is formed and the sachet or the like is stored in the recess. In particular, when the food is natto, the hand is easily soiled by sticky natto thread when eating. For this reason, as in the case of the natto container described above, it is known that measures are taken so that the hand is not soiled as much as possible by preventing the sachet or the like from coming into direct contact with natto.

By the way, when natto is eaten, it is usually eaten after properly adding a seasoning or a condiment to natto and stirring them well. In particular, natto has a texture and flavor that increases as it is stirred, so the natto container plays a role as a container for stirring natto in addition to a role as a container for containing natto.
However, the conventional food containers including the natto containers described above have room for improvement in terms of containers for mixing food such as natto.

  The present invention has been made in consideration of such circumstances, and an object of the present invention is to provide a natto container that can stir natto more efficiently in a short time even if the same stirring method as in the prior art is used. That is.

In order to achieve the above object, the present invention provides the following means.
(1) A food container according to the present invention is formed in a bottomed cylindrical shape having a bottom wall portion, and a container main body that contains food, and a bulging portion that bulges upward from a central portion of the bottom wall portion. An uneven portion is formed on the surface of the bulging portion, and the uneven portion surrounds the cylindrical portion while the food is in contact with the outer wall surface of the cylindrical portion inside the container body. When the food is moved in the circumferential direction, the food is overcome, and the food is moved in the concave depression direction and the convex protrusion direction, and the convex and concave portions are continuously formed in the circumferential direction. The convex portions and the concave portions are formed so as to be alternately repeated, and are formed so as to be linear from the top wall toward the bottom wall portion, respectively, and the upper end portion of the convex portion and the upper end portion of the concave portion It is characterized by being located away downward from each of the top wall

In the food container according to the present invention, when the seasoning is added to the food contained in the container body and stirred, the food mainly contacts the outer wall surface of the cylinder part and mainly around the cylinder part in the circumferential direction. It is stirred while being moved. At this time, since the concavo-convex portion is formed on the outer wall surface, each time the food gets over the concavo-convex portion, the concave direction of the concave and the protruding direction of the convex (direction different from the circumferential direction / hereinafter referred to as the other direction). Moved. Thereby, with respect to the foodstuff mainly stirred along the circumferential direction, the force moved to another direction can be applied suitably, and the movement of foodstuff can be changed.
Therefore, even if it is the same stirring method as before, food can be stirred more efficiently in a short time.

  Moreover, since the seasoning is accommodated in the hollow part formed in the top wall of the cylinder part, the seasoning can be quickly added to the food, and the hand is hardly stained. Moreover, since the cylinder part is standingly arranged in the center part of the bottom wall part, the circumference | surroundings are enclosed and protected by the container main body. Therefore, it is difficult for external force to be applied to the cylindrical portion including the recessed portion in the distribution process or the like, and the seasoning can be stored more safely.

Furthermore , in the food container according to the present invention, since the concave and convex portions are formed so that the convex portions and the concave portions are continuously and alternately repeated in the circumferential direction, the convex portions and the concave portions are alternately overcome during the stirring. So that the food moves. Therefore, it is possible to stir mainly along the circumferential direction while moving the food more frequently in the other direction at the time of stirring. Therefore, a big change of movement can be given to food, and it can stir more efficiently.

( 2 ) The food container according to the present invention is characterized in that, in the food container of the present invention, the cylindrical portion is formed in a frustum shape that gradually increases in diameter from the top wall toward the bottom wall portion. And

  In the food container according to the present invention, the cylindrical portion is formed in a frustum shape, and the diameter is larger as it is closer to the bottom wall portion side, and the surface area in contact with the food is larger. Normally, when food is stirred, the food tends to accumulate on the bottom side of the container body, so that the amount of food tends to increase as the distance from the bottom wall portion increases. However, as described above, since the surface area of the tube portion increases as it approaches the bottom wall portion, the food is more easily in contact with the outer wall surface of the tube portion. Therefore, efficient stirring is possible even at a position close to the bottom wall.

( 3 ) The food container according to the present invention is characterized in that, in the food container of the present invention, the cylindrical portion is formed in a truncated cone shape, and the container body is formed in a circular shape in plan view. .

In the food container according to the present invention, the cylindrical portion is formed in a truncated cone shape, and the container body is formed in a circular shape in plan view. Therefore, the outer wall surface of the cylindrical portion and the inner wall surface of the container main body have a smooth shape with no protruding corners. Therefore, the mixing operation can be performed without being caught by the outer wall surface of the cylindrical portion and the inner wall surface of the container body. Therefore, it can stir more efficiently.
Further, since the cylindrical portion is formed in a truncated cone shape and the container main body is formed in a circular shape in plan view, alignment around the central axis passing through the center of the container main body is unnecessary. Therefore, when each food and seasoning is accommodated, it is not necessary to rotate the food container itself in the circumferential direction to position a specific position with respect to the apparatus. Therefore, food and seasonings can be quickly accommodated, and in this respect as well, the production efficiency can be improved.

  According to the food container of the present invention, food can be stirred more efficiently in a short time even if it is the same stirring method as before, and food can be eaten quickly.

  Hereinafter, an embodiment of a food container according to the present invention will be described with reference to FIGS. 1 to 5. In this embodiment, natto is taken as an example of food, and a natto container that accommodates this natto is described as a food container.

The natto container 1 of this embodiment is provided with the container main body 2 which accommodates the natto B, and the sheet | seat body (lid body) 3 which seals the container main body 2 as shown in FIG.1 and FIG.2.
FIG. 1 is an external perspective view (partially sectional view) of the natto container 1. FIG. 2 is a cross-sectional view of the natto container 1 shown in FIG. Further, an axis passing through the center of the container body 2 is referred to as a central axis O, a direction orthogonal to the central axis O is a radial direction, and a direction around the central axis O is a circumferential direction.

  First, the sheet body 3 is a thin sheet formed of a material such as metal foil, paper, or a resin film (sheet), and is attached to the upper surface of a flange portion 2a described later by adhesion or the like. Thereby, the container main body 2 in which the natto B is accommodated can be covered, and the inside is sealed. The sheet body 3 can be easily peeled off when necessary and removed from the container body 2.

As shown in FIGS. 3 to 5, the container body 2 is a cup-shaped container made of a synthetic resin made of polystyrene or the like or made of a material other than a synthetic resin such as paper, and the bottom wall portion 10 and the peripheral wall portion 11 are It has a bottomed cylindrical shape.
FIG. 3 is a perspective view of the container body 2. FIG. 4 is a perspective view of a part of the container body 2 as viewed in cross section. FIG. 5 is a top view of the container body 2 as seen from the direction of the arrow A shown in FIG.

  A cylindrical portion 15 is formed in a substantially central portion of the bottom wall portion 10 so as to stand upward toward the opening end. The cylindrical portion 15 of the present embodiment has a top wall 16 and is formed in a truncated cone shape that gradually increases in diameter from the top wall 16 toward the bottom wall portion 10. Further, as shown in FIG. 2, the cylindrical portion 15 is set so that the top wall 16 is in contact with the sheet body 3 that closes the open end of the container body 2.

As shown in FIGS. 3 to 5, an uneven portion 17 is formed on the outer wall surface of the cylindrical portion 15. The concavo-convex portion 17 of the present embodiment is formed such that the convex portions 17a and the concave portions 17b are alternately repeated in the circumferential direction. These convex portions 17a and concave portions 17b are formed so as to be linear from the top wall 16 toward the bottom wall portion 10, respectively.
Although the said recessed part 17b is comprised by the outer wall surface between the convex parts 17a, it can also be made into the recessed part which protrudes inward from a cylindrical part further from this outer wall surface.
The top wall 16 is formed with a recess 18 in which the seasoning is accommodated. In this embodiment, as shown in FIG.1 and FIG.2, the saucer W solidified by the jelly shape as a seasoning is accommodated in this hollow part 18. As shown in FIG.

The container body 2 is formed in a circular shape in plan view, and a flange portion 2a bent outward in the radial direction is formed on the opening end surface. As described above, the sheet body 3 is attached to the upper surface of the flange portion 2a.
Further, similarly to the outer wall surface of the cylindrical portion 15, an uneven portion 19 is formed on the upper surface of the bottom wall portion 10 so that the convex portions 19 a and the concave portions 19 b are alternately repeated in the circumferential direction. ing. The convex portions 19a and the concave portions 19b are each formed to be linear along the radial direction.
The concave portion 19b is composed of the bottom wall portion 10 between the convex portions 19a, but may be a concave portion that further protrudes toward the lower surface side of the bottom wall portion 10.

Next, the case where the natto container 1 comprised in this way is used is demonstrated.
First, the sheet 3 shown in FIG. 1 is removed from the container body 2 to expose the natto B and the sauce W. Next, after adding sauce W to natto B, natto B and sauce W are well agitated. Then, the natto B is stirred inside the container body 2 while being moved around the cylindrical portion 15 in the circumferential direction mainly in contact with the outer wall surface of the cylindrical portion 15.

At this time, since the concavo-convex portion 17 is formed on the outer wall surface of the cylindrical portion 15, the natto B is moved in the other direction (mainly in the radial direction) every time it gets over the concavo-convex portion 17. That is, by using the concavo-convex portion 17, it is possible to appropriately apply a force for moving the natto B that is mainly stirred along the circumferential direction in the other direction, and to change the movement of the natto B. .
In particular, in the present embodiment, since the concavo-convex portions 17 are formed so that the convex portions 17a and the concave portions 17b are alternately repeated in the circumferential direction, the convex portions 17a and the concave portions 17b are alternately arranged during the stirring. Natto B can be moved to get over. Therefore, it is possible to stir mainly in the circumferential direction while moving natto B in the other direction more frequently during the stirring. Therefore, a larger change in movement can be applied to natto B.

As a result, even if it is the same stirring method as before, natto B can be stirred more efficiently in a short time, and natto B can be eaten quickly.
In particular, the cylindrical portion 15 is formed in a truncated cone shape, and the diameter is larger as it is closer to the bottom wall portion 10 side, and the surface area in contact with the natto B is larger. For this reason, it is possible to reliably change the movement of the natto B accumulated on the bottom wall portion 10 side by the uneven portion 17.

Furthermore, in this embodiment, since the uneven part 17 is formed also in the upper surface of the bottom wall part 10 of the container main body 2, the movement of the natto B can be further changed by these uneven parts 17, Also in terms of efficiency, efficient stirring can be performed.
In addition, since the cylindrical portion 15 is formed in a truncated cone shape and the container main body 2 is formed in a circular shape in plan view, both the outer wall surface of the cylindrical portion 15 and the inner wall surface of the container main body 2 protrude. It has a smooth shape with no corners. Therefore, the mixing operation can be performed without being caught on the outer wall surface of the cylindrical portion 15 and the inner wall surface of the container body 2. Therefore, also in this point, it becomes easy to stir and efficient stirring can be performed.

  In addition, since the sauce W is solidified in a jelly shape and is contained in the recess 18 provided in the top wall 16 of the cylindrical portion 15, it can be quickly added to the natto B and the hands are not easily soiled. Very easy to use. Moreover, since the cylindrical portion 15 is erected at the substantially central portion of the bottom wall portion 10, the periphery is surrounded and protected by the container body 2. Therefore, it is difficult for an external force to be applied to the cylindrical portion 15 including the hollow portion 18 in the distribution process or the like, and the saucer W can be stored more safely.

Moreover, according to the natto container 1 of this embodiment, there can exist the following effects at the time of manufacture.
First, since the cylinder part 15 is formed in a truncated cone shape and the container body 2 is formed in a circular shape in plan view, alignment around the central axis O is unnecessary. Therefore, when storing the natto B and the sauce W, it is not necessary to rotate the natto container 1 itself in the circumferential direction to position a specific position with respect to the apparatus. Therefore, the natto B and the sauce W can be quickly accommodated, and the production efficiency can be improved.

  Moreover, since the height of the cylinder part 15 is set so that the top wall 16 contacts the sheet body 3, when the sheet body 3 is attached to the flange part 2a and the container body 2 is sealed, the sagging W is simultaneously The recessed part 18 accommodated can also be covered. Therefore, the manufacturing process can be simplified. Moreover, since the top wall 16 is in contact with the sheet body 3, it is possible to prevent the sauce W from being erroneously mixed into the natto B side in the distribution process or the like.

  The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.

  For example, in the said embodiment, although the natto container 1 which accommodates natto B was mentioned as an example and demonstrated as an example of a food container, it is not limited to this.

  In the above embodiment, the case where the container body 2 is sealed using the sheet body 3 has been described as an example. However, the lid body that can be opened and closed via the hinge portion is connected to the flange portion 2 a of the container body 2. It is also possible to seal the container body 2 using this lid. At this time, it is preferable that a perforation that can be broken is formed in the hinge portion, and the perforation is broken after the lid is opened so that the lid can be removed from the container body 2.

Moreover, in the said embodiment, although the uneven | corrugated | grooved part 17 was formed in the outer wall surface of the cylinder part 15 so that the convex part 17a and the recessed part 17b might be formed alternately in the circumferential direction, it is not restricted to this case. Absent. In the reference example of the present invention , any uneven portion such as a spiral shape or a hemispherical shape may be formed on the entire outer wall surface or a part of the cylindrical portion 15. Even in this case, it is possible to change the movement of natto B which is being stirred by stirring, and contribute to efficient stirring.

Moreover, in the said embodiment, although the sauce W hardened | cured to the jelly shape was mentioned as an example as an example of a seasoning, the forms accommodated, such as a gel form and a solid form, are not limited to this case. For example, a liquid sauce placed in a sachet may be stored in the recess 18 as a seasoning, and the recess 18 is configured to be liquid-tightly sealed by the sheet body 3 so that the liquid seasoning The fee may be stored directly. Furthermore, you may accommodate 1 type or multiple types of seasonings other than sauce, such as a hot pepper, and additives (spicy etc.) other than seasonings. In any case, as long as it is added to natto B, it may be accommodated in the recess 18 as a seasoning.
Further, food other than natto B and other products may be accommodated in the container body 2.

Moreover, in the said embodiment, although the cylinder part 15 was formed in the truncated cone shape, you may form in a truncated pyramid shape, and you may form in cylindrical shapes, such as a cylinder shape and a polygonal shape in a top view. The container body 2 is also formed in a circular shape when viewed from above, but may be formed in a polygonal shape or an elliptical shape when viewed from above.
Moreover, you may form an uneven | corrugated | grooved part in an inner wall surface similarly to the bottom wall part 10 of the container main body 2. FIG. By doing so, it is possible to make it easier to stir natto B more efficiently.
Furthermore, the axial length and width of the concavo-convex part, the number of formations, and the like are not limited.

  Furthermore, in the said embodiment, although the height of the cylinder part 15 was set so that the top wall 16 might contact the sheet | seat body 3, a cylinder part of a cylinder part was opened so that a fixed clearance gap might be opened between the top wall 16 and the sheet | seat body 3. You may set the height. Moreover, you may adhere | attach the top wall 16 and the sheet | seat body 3 of a contact state so that peeling is possible. In this case, the sealing property of the hollow part 18 is enhanced.
