JP6231756B2 - Packaging containers for sushi - Google Patents

Description

  The present invention relates to a packaging container for “flowing up” sushi, and more particularly to a packaging container thermoformed from a synthetic resin sheet.

  Sushi is sometimes eaten at a sushi restaurant, but it is sometimes taken home and eaten at a party or party venue that is said to be a “meal”. When you take sushi home and eat it, you need a “container” to take it home. In recent years, instead of “sushi bowl” that must be returned to a sushi restaurant, this can be a disposable synthetic resin. Large amounts of packaging containers made of plastic are used.

  On the other hand, since sushi itself can be offered in a large amount at a lower price than what sushi craftsmen make by hand, more and more are made mechanically. Even for sushi made mechanically, in order to place it in the packaging container, it is necessary to rely on human hands.

  By the way, when serving a plurality of sushi in a container, a method of “flowing” is adopted. Unlike the traditional “pile-up” method, “sashimi” is a method of arranging sushi in a flat manner like a river flow without stacking up and down, and fingers and chopsticks are placed on both sides of the sushi. So that it is easy to put in, it is "tilted" for the eater.

  A certain level of skill is required to perform such “flowing” in a short period of time on a large amount of sushi coming out from a sushi production apparatus in a sushi packaging container. For this reason, the packaging container for flowing sushi needs to be devised.

  Various packaging containers for storing sushi have already been proposed in Patent Document 1, Patent Document 2, and the like.

Japanese Utility Model Publication No. 4-22874, FIG. JP-A-11-70930, abstract

  As shown in FIG. 11, the “plastic sushi bowl” proposed in Patent Document 1 has “a plurality of linear ridges for partitioning sushi to be placed inside a plastic sushi bowl. Projecting at an interval of "." The “plastic sushi bowl” of Patent Document 1 has a circular outer shape as shown in FIG. 11, so it does not have the overall direction of appearance, but the sushi is neatly made using the ridges for partitioning the sushi to be served. When trying to serve, the direction will suddenly come out, and the "plastic sushi bowl" must be installed so that the ridges can be used.

  Furthermore, when trying to pour sushi with the “plastic sushi bowl” of Patent Document 1, it is considered that “a plurality of linear protrusions for partitioning sushi” makes it difficult to arrange the sushi. Because, the installation direction of the “plastic sushi bowl” itself differs depending on the skill level and cocoon of the arrangement worker, and this installation direction may differ from the direction of “multiple straight ridges” This is because it is necessary to correct the installation direction of the “plastic sushi bowl” itself.

  Further, “Packaging Container and Method for Producing the Same” in Patent Document 2 describes “a container for packaging suitable for storing liquids such as soy sauce and sauce such as sushi and mitarashi dumpling and a method for producing the same. 12, as shown in FIG. 12, “the four corners of the rectangular plate-like body are cut off and the side walls 13 between the four corners forming the footrests are raised to form the side wall ends. A container in which the portions 13 'are fusion-bonded to each other, and a storage concave portion having a bottom surface at a central position slightly lowered from the upper end of the side wall is formed, and the concave portion or the convex portion forming the small section 12 in the storage concave portion 11 Are integrally formed. "

  Although the “packaging container” of this Patent Document 2 may be able to store liquid materials such as soy sauce and sauce using the small compartment 12, it does not take into account the “sashimi” of sushi, It seems that skill is required to perform a large amount of sinking work in a short time.

  In any case, when trying to pour a large amount of sushi from the sushi production device into the specified packaging container within a short time, first determine the position of the whole container so that it is easy to work, Although sushi must be arranged in order on the bottom of the container, it is considered that it takes time to position the container in the conventional container.

  In particular, when selling large quantities of sushi at a large store such as a supermarket, the number of sushi to be stored in a specified container (usually consistent with 2 nigiri sushi, but below, nigiri sushi 1 (It is assumed that the individual is consistent) is of course determined, so there must be no mistakes in the number itself, and the appearance of each container may not be different. The important thing is that workers who serve sushi in large yards such as supermarkets are often not professional sushi chefs, so even unskilled people like this Therefore, there is a need for a container that can produce a beautiful sink in a short time without any mistakes.

  Therefore, the present inventors have conducted various studies on how to make a container that can easily and neatly serve sushi, even for unskilled people. It was completed.

  In other words, the object of the present invention is that, regardless of the orientation, the standard position of the sushi to be served always appears at the same position, and even an unskilled person can serve the sushi serving. An object of the present invention is to provide a packaging container for sushi that can be easily cleaned in a short time and without any mistakes.

In order to solve the above problems, first, the means taken by the invention according to claim 1 will be described with reference numerals used in the description of the best mode described below.
“In the packaging container 10 for pouring a plurality of sushi 20 on the square bottom 10a in plan view,
In each of the straight sides of the bottom surface 10a, inclined at the same angle θ with respect to each side to form a first rib 11 formed in a guide for Serve the first sushi 20a,
Furthermore, in order to arrange the next sushi 20b on the right side of the first sushi 20a arranged with the first rib 11 as a guide, a second slant parallel or perpendicular to the first rib 11 is provided on the bottom surface 10a. Forming ribs 12;
The first rib 11 that is inclined at an angle θ with respect to the side has no other first rib 11 or second rib 12 formed between the side and the first rib 11 with respect to the adjacent side. The packaging container 10 for sushi characterized by extending in a direction orthogonal to the rib 11 "
It is.

  The packaging container 10 according to the present invention is formed by thermoforming from a synthetic resin sheet, and as shown in FIGS. 1 to 5, a rising wall is provided around the entire bottom surface 10 a on which the sushi 20 is to be placed. 16 are continuous, and the sushi 20 forms a storage portion for the sushi 20. Further, a flange 17 is integrated with the entire upper end of the sushi 20, and a part of the rigidity required for the packaging container 10 is secured by the flange 17 and is fitted to the packaging container 10. A placement place for the lid 30 to be joined is secured.

  Moreover, although the container 10 for packaging based on this invention presupposes that the bottom face 10a has comprised the regular polygon, the regular polygon in this case is (a) of FIG. As shown in b), for example, a portion that is a corner of a regular square is also included that is “rounded” with an arc or a straight line. Of course, the fact that the bottom surface 10a is a regular polygon means that there are a number of “sides” around the bottom surface 10a according to the number of angles of the regular polygon. That is, it forms a square.

  Further, the premise that the bottom surface 10a is a regular polygon is that the flange 17 that forms the outer shape of the packaging container 10 itself and the rising wall 16 between the flange 17 and the bottom surface 10a. It also means that it has a shape, that is, it does not matter how the outer shape of the packaging container 10 itself is. For example, the case where the bottom surface 10a is a regular triangle or a regular square and the outer shape of the packaging container 10 is a circle or an ellipse is also an object of the present invention.

  In the packaging container 10 according to the first aspect, for example, as shown in FIGS. 1 and 2, the first sushi 20 is placed in the vicinity of each side of the bottom surface 10 a at the same angle θ with respect to each side. The 1st rib 11 used as a standard for this is formed. Since this 1st rib 11 becomes a standard used when the arrangement operator arranges the sushi 20, it may be convex or concave with respect to the bottom surface 10a, Although the length is not limited, it is preferable that the length is as straight as possible in the sense of indicating directionality.

  If the surface of the first rib 11 is formed with fine irregularities so that light is diffusely reflected, when the other part of the inner surface of the bottom surface 10a shines, the first rib 11 is lifted in the light. Therefore, it is easy to use as a guide.

  Regarding the packaging container 10 configured as described above, the operation of pouring and piling the sushi 20 on the bottom surface 10a will be described in the following order in the case where the bottom surface 10a is a regular square. First, a large number of stacked packaging containers 10 are placed near a discharge port of a sushi manufacturing apparatus or a conveyor belt, for example. Take one and place it on a workbench where it is easy to work.

  When this packaging container 10 is placed on a workbench, an operator who is generally “right-handed” causes one side of the bottom surface 10a to be horizontal on the upper side when viewed from the operator. Because, in order to arrange several sushi 20 in order, it is natural to start from the left back of the top row, and when this top row ends, move to the row immediately below and start again from the left back That's why. When the packaging container 10 is arranged so that one side of the bottom surface 10a is horizontal on the upper side when viewed from the operator, the first rib 11 in an inclined state with respect to the side is always near the side. appear. If the appearance position and the inclination angle θ of the first rib 11 satisfy the condition that one side of the bottom surface 10a is horizontal on the upper side, the packaging container 10 is placed on the work table with which side is the upper side. It ’s always the same no matter where you put it.

  In other words, when the packaging container 10 is arranged so that one side of the bottom surface 10a is horizontal on the upper side so that the worker can easily arrange the first rib 11, the first rib 11 always appears at the position where the arrangement operation is started. Since the first rib 11 is inclined at the same angle θ with respect to a side in the vicinity thereof, the sushi 20 is arranged along the first rib 11, that is, with the first rib 11 as a guide. The first sushi 20a is always placed obliquely at an angle necessary for “flowing”.

  If the first sushi 20a is always placed obliquely at the angle required for “flowing”, as shown in FIG. 2, the state of the first sushi 20a itself or the horizontal side on the upper side, By using the “sushi” as a guide for the next sushi 20b, the operator places the first sushi 20a as a guide and places the next sushi 20b on the right next to the serving. Is easy to do. Of course, if the placement operation is moved to the lower row, the placement state of the first sushi 20a and the row state formed by these will be the “guideline for flowing the sushi 20 in the next row. Needless to say, "

  If the first rib 11 is used as a guide, the sushi 20 is formed in substantially the same size by the sushi manufacturing apparatus, so the total number of sushi 20 after the completion of the flow is always the same. There is no error in the number of sushi 20 to be stored in the packaging container 10.

  As a result of the above, as long as the condition that one side of the bottom surface 10a is horizontal on the upper side (this is a natural operation), whatever the arrangement of the packaging container 10, Whatever the number of corners of the bottom surface 10a which is a regular polygon, the position where the first sushi 20a should be placed is always indicated by the first rib 11 appearing at the same position, and the work is not skilled. Even if you are a person, you can clean the sushi 20 well.

  Therefore, the packaging container 10 according to claim 1 can be placed in any orientation, and the standard position of the sushi 20 to be served always appears at the same position. The 20 sinks can be easily performed in a short time and without any mistakes.

In order to solve the above problems, the means taken by the invention according to claim 1 is about the packaging container 10 for the sushi 20 described above.
“In order to place the next sushi 20b on the right side of the first sushi 20a that is arranged using the first rib 11 as a guide, the second rib 12 that is inclined parallel or perpendicular to the first rib 11 is provided on the bottom surface 10a. That formed "
It is.

  In the packaging container 10 according to the first aspect, as shown in FIG. 3, the bottom rib 10a is formed with the second rib 12 inclined parallel or perpendicular to the first rib 11. The 2 ribs 12 serve as a standard when the next sushi 20b is placed on the right side of the first sushi 20a arranged with the first rib 11 as a guide.

  First, in the example shown in FIG. 3, the bottom surface 10 a is a regular square, and three rows of sushi 20 are placed in one row, and this row is divided into three rows, and a total of 9 pieces of sushi 20 are stored. However, the following explanation is recommended mainly in this case. Of course, in this packaging container 10, the 1st rib 11 which inclines at the same angle (theta) with respect to each edge | side in the vicinity of each edge | side of the bottom face 10a, and becomes a standard for placing the first sushi 20a is formed. Needless to say.

  Each second rib 12 needs to be inclined parallel or perpendicular to the first rib 11 because of the shape of each sushi 20. Each sushi 20 is formed by placing various types of “sna” on “sushi rice”, and “sushi rice” is formed in a substantially rectangular fixed shape, Many of the “spoons” are so large that they squeeze out of “sushi rice” and the shape is not constant. Therefore, when placing each second rib 12 on the bottom surface 10 a as a guide, it may be unclear which part on the sushi 20 side should be aligned with the second rib 12.

  As described above, in order to pour a plurality of sushi 20, the first sushi 20 a is first placed using the first rib 11 on the upper left side of FIG. The sushi 20b should be arranged in parallel to the right of the first sushi 20a. Therefore, if the second rib 12 is formed in parallel with the first rib 11 and this can be seen without being disturbed by the “stitch”, the second rib 12 will replace the next sushi 20b with the first sushi 20a. This is a guideline for placing them in parallel.

  On the other hand, as shown in FIG. 7, when placing the next sushi 20b in parallel with the first sushi 20a, the material of the sushi 20 has a complicated shape, but the sushi rice has a “rectangular shape”. If the second rib 12 as a guide indicating the position to be placed is at right angles to the first rib 11 in a case where it can be clearly understood, the sushi rice constituting the next sushi 20b If the lower short sides are combined, the next sushi 20b can be easily placed in parallel with the first sushi 20a. This is the reason for forming the second rib 12 inclined at a right angle to the first rib 11. Of course, these second ribs 12 are not limited to the sushi rice of the sushi 20b as a guide. For example, if the cut of the material is straight, the straight portion of the material is the second. What is necessary is just to match | combine with the standard by the rib 12. FIG. The operator may select the sushi rice or the material as appropriate for each time.

  In the above example in which the bottom surface 10a is a regular square and the sushi 20 has 3 rows and 3 columns, the number of the second ribs 12 adjacent in parallel to the first ribs 11 is “1”. It goes without saying that if the number of sushi 20 increases to 4, 5, 6,..., The number of second ribs 12 can also increase to 2, 3, 4,.

  Therefore, in the packaging container 10 according to the first aspect, the second rib 12 can provide a guideline for pouring the next sushi 20b next to the first sushi 20a.

Further, the means taken by the invention according to claim 1 is about the packaging container 10 for the sushi 20 described above.
"The bottom surface 10a is a square in plan view"
It is.

  In the packaging container 10 of the first aspect, as shown in FIGS. 1 to 5, the shape of the bottom surface 10a is a square in plan view, that is, a regular square. The condition that the packaging container 10 is arranged so that one side of the bottom surface 10a is horizontal on the upper side described in the description can be more easily cleared.

  This is because, for example, a rail for bringing the packaging container 10 into contact with the work table is made parallel to the operator, and the packaging container 10 is placed on the work table so as to be in contact with the work bar. This is because, naturally, one side of the bottom surface 10a becomes horizontal on the upper side if it is placed.

  Therefore, the packaging container 10 according to claim 1 can easily level one side of the bottom surface 10a on the upper side.

Furthermore, in order to solve the said subject, the means which the invention which concerns on Claim 2 took about the packaging container 10 for sushi 20 of the said Claim 1,
“Third ribs 13 are formed on the bottom surface 10a so as to define the arrangement range of each sushi 20 in parallel with each side.”
It is.

  In the packaging container 10 of this second aspect, as shown in FIGS. 4 and 5, third ribs 13 parallel to the respective sides are formed on the bottom surface 10 a. If the arrangement range of the sushi 20 is defined, and the third ribs 13 are used during the pouring work, the work will progress. That is, even if any packaging container 10 is taken, a uniform and clean filling can be made.

  Since the third rib 13 defines the arrangement range of each sushi 20, there is almost no restriction on the shape and size, or whether it is concave or convex. Of course, the third ribs 13 are most preferably linear, as in the first ribs 11 described above, and may be implemented by processing to diffusely reflect light.

  Therefore, the packaging container 10 according to the second aspect exhibits the same function as the packaging container 10 for the sushi 20 according to the first aspect, and can further accurately and accurately place the sushi 20. It is a thing.

As described above, in the present invention,
“In the packaging container 10 for pouring a plurality of sushi 20 on the square bottom 10a in plan view,
Each of the sides near the bottom surface 10a, inclined at the same angle θ with respect to each side to form a first rib 11 formed in a guide for Serve the first sushi 20a,
Furthermore, in order to arrange the next sushi 20b on the right side of the first sushi 20a arranged with the first rib 11 as a guide, a second slant parallel or perpendicular to the first rib 11 is provided on the bottom surface 10a. Forming ribs 12;
The first rib 11 that is inclined at an angle θ with respect to the side has no other first rib 11 or second rib 12 formed between the side and the first rib 11 with respect to the adjacent side. The ribs 11 extend in directions perpendicular to each other. "
The main feature of the structure of the sushi 20 is that, regardless of the orientation of the sushi 20, the standard position of the sushi 20 to be served always appears at the same position. Thus, it is possible to provide the packaging container 10 for the sushi 20 that can be easily and smoothly prepared within a short time and without any mistakes in the number of pieces.

It is a claim corresponding figure for demonstrating the invention which concerns on Claim 1 of this application.

  Next, the invention according to each claim configured as described above will be described with reference to the packaging container 10 according to the embodiment shown in the drawings. FIG. 5 shows the packaging container according to the first embodiment of the present invention. FIG. 7 shows a packaging container 10 according to the second embodiment of the present invention. The packaging container 10 according to each of these examples is a sheet made of various materials and formed into a sheet having excellent lightness and economy, and a synthetic resin sheet is preferable as the sheet. The synthetic resin sheet is preferably made of polypropylene, polyethylene terephthalate, biaxially stretched polystyrene, polylactic acid, polyethylene, or polystyrene.

(First embodiment)
FIG. 5 (a) shows a plan view of the packaging container 10 according to the first embodiment of the present invention. The packaging container 10 has a bottom surface 10a having a "rectangular shape" in plan view. As shown in FIG. 8, a rising wall 16 and a flange 17 are sequentially formed around the bottom surface 10a. In particular, the flange 17 forms the outline of the packaging container 10 in plan view. In the present embodiment, the flange 17 is also formed in a “regular square” in plan view. The flange 17 and the rising wall 16 may be fitted with a lid 30 as shown in FIG.

  The bottom surface 10a of the packaging container 10 is a "rectangular shape", that is, a square in a plan view. In this case, the regular square is a corner of a regular square as shown in FIGS. 6 (a) and 6 (b). This includes parts that are “rounded” with arcs or straight lines. In addition, as shown in FIGS. 2, 4, and 5B, the packaging container 10 of the present embodiment has three rows of sushi for one horizontal row with respect to the regular square bottom surface 10a. No. 20 is placed, and this row is divided into three upper and lower rows so that a total of 9 pieces of sushi 20 can be placed. In addition, the size of the sushi 20 is that the size of the material is in the range of 60 to 80 mm in length and 25 to 35 mm in width, and the size of the sushi rice is 49 to 68 mm in length and 21 to 36 mm in width. Is assumed to be within the range of

  When the packaging container 10 is formed into a sheet, the first rib 11, the second rib 12, the third rib 13, and the fourth rib 14 are simultaneously formed on the bottom surface 10 a as linear ones. The first rib 11, the second rib 12, the third rib 13, and the fourth rib 14 may be convex or concave with respect to the bottom surface 10a, and the width and length are Although not limited, in this embodiment, it is convex with respect to the bottom surface 10a. The first rib 11 and the second rib 12 in the present embodiment have the same length of 10 mm and the same width as 2 mm, and are inclined at 45 ° with respect to each side. The third rib 13 has a width of 3 mm and a length of 28 mm, and is formed so as to be parallel to each side to form a so-called “grid eye”. The fourth rib 14 has a length of 5 mm, which is the shortest of the ribs.

  In particular, in the packaging container 10 of the present embodiment, the bottom surface 10a has a square shape in plan view. Therefore, when the bisector 15 is considered at each corner, each of the bisector 15 on both sides The angle with respect to the side is 45 °. In other words, the angle θ of the bisector 15 with respect to the upper side is 45 °, but this angle of 45 ° is used as an inclination angle when a plurality of sushi 20 is “running”. It is a suitable angle. Of course, the angle [theta] is not limited to 45 [deg.], And it is sufficient that the angle [theta] is tilted at an angle that allows the sinking. Furthermore, if the angle θ is within the range of 30 ° to 60 °, it is easy to “pick up” and it is easy for the eater to easily obtain the sushi 20.

  Therefore, in the packaging container 10 of the present embodiment, as shown in FIG. 5, the first rib 11 and the second rib 12 are parallel to each other at the line symmetry positions of the bisectors 15 of the bottom surface 10a. For example, the first rib 11 located in the upper left of FIG. 5 is inclined at an angle of 45 ° with respect to the adjacent side, and is a guideline for serving the sushi 20a in the left back shown in FIG. The second rib 12 that is parallel to the first rib 11 serves as a guideline for placing the next sushi 20b on the right side of the sushi 20a at the left back.

  In other words, the first ribs 11 and the second ribs 12 formed so as to be parallel to each other at the line symmetric positions of the bisectors 15 of the bottom surface 10a have the sushi 20 disposed obliquely, that is, “ An inclination direction for “running” is shown, and a space between the first rib 11 and the second rib 12 shows a place where the sushi 20 is placed. Moreover, the 2nd rib 12 parallel to the 1st rib 11 and adjoining this is also a standard for serving the next sushi 20b.

  Since the packaging container 10 of the present embodiment is for placing a total of 9 pieces of sushi 20 in 3 vertical and horizontal directions, next to the second ribs 12 that are parallel to and adjacent to the first ribs 11. In addition, a second second rib 12 is formed in parallel with the width of the sushi 20. A first rib 11 for the next corner is formed on the right side of the second second rib 12.

  Each third rib 13 forms a “grid eye” by being parallel to each side, and as shown in FIG. 4, the bottom surface 10 a on which these third ribs 13 are formed is 3 in length and breadth. It shows that 9 pieces of sushi 20 in total are placed. That is, these third ribs 13 indicate rough placement locations of each sushi 20 assuming that the shape of the sushi 20 is not specified due to the complicated shape of the material. Furthermore, when the sushi 20 is arranged on the basis of the third ribs 13, the sushi positions in the horizontal (or vertical) direction are aligned, and the sushi can be placed beautifully. Each third rib 13 is parallel to each side and is formed with a length different from that of the first rib 11 and the second rib 12, so that an operator can use these ribs and the third rib 13. Can be clearly distinguished, and the sushi 20 can be served without confusing each rib.

  Each of the fourth ribs 14 prevents the sushi 20 from moving and breaking when the sushi 20 is placed on the bottom surface 10a in an orderly manner, even when the packaging container 10 is vibrated or shaken. It is. In other words, these fourth ribs 14 do not have to be linear, and may be point-like so that the arrangement of the sushi 20 is less likely to collapse. In addition, since each 4th rib 14 is formed in the length and angle which are different from the 1st rib 11, the 2nd rib 12, and the 3rd rib 13, an operator is these 4th rib 14 and other ribs, Can be clearly distinguished. Of course, since each rib has a different length and shape, the operator can mix the ribs without hesitation and can fill the sushi 20 without hesitation.

(Second embodiment)
FIG. 7 shows a plane of the bottom surface 10a constituting the packaging container 10 according to the second embodiment. The plan view shape of the bottom surface 10a is a regular pentagon, and it is assumed that the sushi 20 is poured over each side as shown in FIG. It is assumed that a large number of people eat the sushi 20 by surrounding the packaging container 10, and for example, as shown in FIG. 9B. The sushi 20 in the portion surrounded by the bisector 15 is made visible to the human eye.

  Now, in the packaging container 10 of this 2nd Embodiment, each 1st rib 11 formed in the bottom face 10a inclines at the same angle (theta) with respect to each edge | side, and becomes a standard for placing the first sushi 20a. Is the same as in the first embodiment described above, but each second rib 12 for placing the next sushi 20b on the right side of the first sushi 20a served with the first rib 11 as a guide is provided as a first rib. 11 is different from that of the first embodiment in that it is inclined at a right angle to 11.

  As shown in FIG. 7, the second ribs 12 provided at right angles to the first ribs 11 serve as a standard for arranging the lower short side of the sushi rice in the next sushi 20b. For example, in the case of “Dai Toro”, “Shrimp”, “Anago”, the shape of the sushi 20 may not be a constant shape depending on the material, or the material may be extremely larger than other sushi. Since the rice is made by a sushi production device, it is often a substantially constant rectangular shape. If the second rib 12 is formed in parallel with the first rib 11, it is wondering where to place the complicated shaped sushi 20 on the second rib 12, but orthogonal to the first rib 11. If it is clear that the second rib 12 is a standard for arranging the lower short side of the sushi rice in the next sushi 20b, the sushi 20 can be poured without hesitation. Of course, as described above, it is needless to say that the filling of the sushi 20b material and the second rib 12 can be used as a guideline and the filling can be performed.

  Of course, in the packaging container 10 according to the second embodiment, for example, as shown in FIG. 9A, the third rib 13 and the fourth rib 14 described in the first embodiment are formed. Needless to say, it may be implemented.
