Description

The present invention relates to a packaging container.

For example, in various stores such as supermarkets and convenience stores, foods such as bento boxes and prepared foods are sold in a packaging container. In foods sold in packaging containers, the appearance such as color and volume is a very important factor that can be linked to consumers' purchasing motivation as well as price. In this regard, a packaging container intended to improve the visibility of the food contained therein is disclosed, for example, in Japanese Patent Application Laid-Open No. 2004-244116 (Patent Document 1).

The packaging container of Patent Document 1 includes a lid 20 having a flat upper surface 21 and an inclined surface 22 formed to have a width of about 1/4 of the upper surface 21. By making the inclined surface 22 to which the label L is affixed about 1/4 of the width of the upper surface 21, the purchaser can easily see the food inside from the center of the flat upper surface 21 which occupies most of the lid 20. It has become.

However, the packaging container of Patent Document 1 has a drawback that it has a flat shape as a whole and requires a large amount of space when it is displayed vertically and horizontally. Especially in recent years, there have been many strong demands for displaying as many products as possible in a limited space, and such demands have not been met.

Japanese Unexamined Patent Publication No. 2004-244116

The trapezoidal groove 23 is formed in a four-corner bulging trapezoidal shape in which the regions corresponding to the four vertices bulge slightly outward. Further, as shown in FIG. 6, a grounding portion 24 for grounding the container body 2 is provided on the outer surface (back surface) side of the container body 2. When the container body 2 is formed by thermoforming a synthetic resin sheet as in the present embodiment, the ground contact portion 24 and the trapezoidal groove portion 23 are in an integral relationship with each other, and the ground contact portion 24 is a trapezoidal groove portion. It is formed in a four-corner bulging trapezoidal shape corresponding to the shape of 23. In the present embodiment, the ground contact portion 24 is formed in an isopod shape. In addition, "grounding" means that it is placed on a workbench, a display table T (see FIG. 9), or the like.

The main body peripheral wall portion 26 extends upward from the peripheral edge of the bottom surface portion 21. The peripheral wall portion 26 of the main body is widened so as to expand outward as it goes upward. The main body peripheral wall portion 26 has a first inclined portion 26A extending upward from the bottom surface portion 21 and a second inclined portion 26B extending upward continuously from the first inclined portion 26A. The inclination angle of the second inclined portion 26B with respect to the bottom surface portion 21 is gentler than that of the first inclined portion 26A. Further, the first inclined portion 26A includes a flat surface portion 26f formed on a flat surface and a curved surface portion 26c formed on a curved surface continuous from both ends of the flat surface portion 26f and surrounding the bottom surface portion 21 together with the flat surface portion 26f. .. As shown in FIG. 2, the flat surface portion 26f is provided at a position corresponding to the lower bottom corresponding portion 22L of the trapezoidal raised portion 22. The curved surface portion 26c is provided at a position corresponding to the upper bottom corresponding portion 22U and the pair of leg corresponding portions 22S of the trapezoidal raised portion 22.

The first inclined portion 26A of the main body peripheral wall portion 26 is formed with a concave portion 27 that is recessed toward the center side of the container main body 2. The concave portion 27 is formed at a plurality of locations. In the present embodiment, the three concave portions 27 are formed on the curved surface portion 26c and are provided at positions corresponding to the upper bottom corresponding portion 22U and the pair of leg corresponding portions 22S of the trapezoidal raised portion 22. By providing such a concave portion 27, the fingers can be hooked on the concave portion 27, and the container body 2 can be easily gripped.

A horizontal rib 28 is formed in the concave portion 27. A plurality of horizontal ribs 28 are formed in each of the plurality of concave portions 27. These horizontal ribs 28 are formed so as to extend parallel to the horizontal plane. Further, the horizontal rib 28 is formed so as to extend along the upper bottom corresponding portion 22U and the pair of leg corresponding portions 22S of the trapezoidal raised portion 22. By providing such a horizontal rib 28, the strength of the concave portion 27 can be increased, and slip prevention can be achieved when a finger is hooked on the concave portion 27.

As shown in FIG. 2, the second inclined portion 26B of the main body peripheral wall portion 26 includes a plurality of triangular surface portions 29. A common side portion (common side portion 29C) between two triangular surface portions 29 adjacent to each other extends diagonally across the main body peripheral wall portion 26. Therefore, the common side portion 29C can impart a larger resistance force to an external force, and can improve the strength of the container body 2. Further, since the common side portion 29C extends diagonally across the peripheral wall portion 26 of the main body, the common side portion 29C itself can be easily visually recognized, and the light reflected by the triangular surface portions 29 on both sides thereof is appropriately dispersed. It will look better. Therefore, the design of the container body 2 can be improved.

Further, an inclined rib 30 is formed on a part of the triangular surface portion 29. The inclined rib 30 is formed so as to extend so as to be inclined with respect to the horizontal plane. In the present embodiment, a plurality of triangular surface portions 29 are sequentially arranged so as to be adjacent to each other in the circumferential direction, and inclined ribs 30 are formed on every other triangular surface portions 29. That is, the triangular surface portions 29 on which the inclined ribs 30 are formed and the triangular surface portions 29 on which the inclined ribs 30 are not formed are alternately arranged in the circumferential direction. In the triangular surface portion 29 on which the inclined ribs 30 are formed, a plurality of inclined ribs 30 are dispersedly provided so as to be arranged in parallel with each other so as to cover substantially the entire area of the triangular surface portion 29.

By providing such an inclined rib 30, the common side portion 29C and the plurality of inclined ribs 30 intersecting the common side portion 29C can cooperate with each other to impart a larger resistance force to an external force, and the strength of the container body 2 can be increased. Can be further improved. Further, the vertices of the plurality of triangular surface portions 29 in which the inclined ribs 30 are formed over substantially the entire area face the same circumferential direction (clockwise in the example of FIG. 2), so that the peripheral wall portion 26 of the main body It is possible to create a dynamic aesthetic as if turning as a whole. Therefore, the design of the container body 2 can be improved.

The main body flange portion 32 extends outward from the upper end portion of the main body peripheral wall portion 26. As shown in FIGS. 2, 4, and 5, the main body flange portion 32 has a linear extending portion 33 extending along a straight line and an arc-shaped extending portion 34 extending along an arc. The linear extending portion 33 is arranged so as to extend along the horizontal plane while the bottom surface portion 21 is in contact with the ground. In the present embodiment, the linear extending portion 33 can also be referred to as a “horizontal extending portion”. The arc-shaped extending portion 34 is arranged so as to be inclined obliquely upward while the container body 2 (bottom surface portion 21) is in contact with the ground. Further, the arc-shaped extending portion 34 is formed so as to extend in an arc shape upward from both ends of the linear extending portion 33. In the present embodiment, the arc-shaped extending portion 34 corresponds to the “tilted extending portion” of the container body 2. A hanging portion 37 is provided on the outer edge of the main body flange portion 32.

In such a configuration, the height of the main body peripheral wall portion 26 is the lowest on the linear extending portion 33 side (the foot portion 34b side of the inclined arc-shaped extending portion 34), and the height of the arc-shaped extending portion 34 It gradually rises toward the top 34t side (see FIG. 4). Therefore, the accommodating capacity of the accommodating portion A formed inside the container body 2 of the arc-shaped extending portion 34 is larger than that of the linear extending portion 33 side (the foot portion 34b side of the arc-shaped extending portion 34). It is larger on the top 34t side.

The top portion 34t is the portion that occupies the highest position in the arc-shaped extending portion 34 with the bottom surface portion 21 in contact with the ground, and the foot portion 34b is the portion that occupies the highest position in the arc-shaped extending portion 34. It is the part that occupies a low position. Further, the height when the bottom surface portion 21 is in contact with the ground is the height from the surface on which the container body 2 is placed, such as a workbench or a display table T (see FIG. 9). If the surface of the display stand T or the like is inclined, it means the height in the direction orthogonal to the inclined surface. In the present embodiment, the top 34t of the arcuate extending portion 34 corresponds to the “maximum height portion” of the container body 2, and the foot portion 34b corresponds to the “minimum height portion” of the container body 2.

In the present embodiment, the trapezoidal raised portion 22 formed on the bottom surface portion 21 is arranged in the following manner in relation to the main body flange portion 32 (linear extending portion 33 and arc-shaped extending portion 34). There is. As shown in FIG. 2, the trapezoidal raised portion 22 is arranged so that its lower base corresponding portion 22L is along the linear extending portion 33 (parallel to the linear extending portion 33). Further, the trapezoidal raised portion 22 is arranged so that the upper bottom corresponding portion 22U is located on the top 34t side of the arc-shaped extending portion 34. That is, in the trapezoidal raised portion 22, the lower bottom corresponding portion 22L is located on the linear extending portion 33 side where the height of the main body peripheral wall portion 26 is relatively low, and the height of the main body peripheral wall portion 26 is relative. The upper bottom corresponding portion 22U is arranged so as to be located on the top 34t side of the high arc-shaped extending portion 34.

By doing so, the accommodation capacity on the top 34t side of the arc-shaped extending portion 34 in the accommodation portion A can be made to appear higher due to the optical illusion effect. By arranging the upper bottom corresponding portion 22U of the trapezoidal raised portion 22 on the top 34t side of the arc-shaped extending portion 34, a sense of depth is created, and the sense of depth makes the peripheral wall portion 26 of the main body on the back side more illusion. Therefore, the accommodation capacity on the back side of the accommodation unit A can be made to appear higher. Therefore, when the container body 2 is accommodated (for example, when food is served), the volume feeling can be enhanced and the appearance can be improved.

Moreover, the horizontal ribs 28 provided in the concave portion 27 for increasing the strength and preventing slipping are formed so as to extend along the upper bottom corresponding portion 22U and the pair of leg corresponding portions 22S of the trapezoidal raised portion 22. .. Therefore, the horizontal rib 28 can increase the presence of the trapezoidal raised portion 22. Therefore, the accommodating capacity on the back side of the accommodating portion A can be made to appear even higher, and the volume feeling can be enhanced to improve the appearance.

The inclination angle θ (see FIG. 6) of the arc-shaped extending portion 34 with respect to the horizontal plane is not particularly limited, but is preferably 7 ° or more and 14 ° or less, for example. When the inclination angle θ is less than 7 °, there is not much difference in the height of the main body peripheral wall portion 26 between the front side and the back side, and it is difficult to sufficiently increase the accommodation capacity of the back side in the accommodation portion A. If the inclination angle θ becomes larger than 14 °, the inner side of the peripheral wall portion 26 of the main body becomes excessively steep, and the stability of the contained object may deteriorate. A more preferable inclination angle θ of the arc-shaped extending portion 34 with respect to the horizontal plane is 8 ° or more and 11 ° or less, and more preferably 9 °.

As shown in FIG. 1, the lid 4 is fitted to the container body 2 so as to cover the upper opening thereof. As shown in FIGS. 1, 3 to 5, the lid 4 includes a top surface portion 41, a lid peripheral wall portion 46, and a lid flange portion 52. The top surface portion 41 forms the ceiling portion of the lid body 4. The top surface portion 41 is formed in a crescent-bon shape (a shape in which a part of a circle is linearly cut out) in a plan view.

The lid peripheral wall portion 46 extends downward from the peripheral edge of the top surface portion 41. The lid peripheral wall portion 46 is formed in an inclined shape so as to expand outward as it goes downward. The lid peripheral wall portion 46 has a rectangular flat surface portion 47 and a plurality of triangular surface portions 48. The rectangular flat surface portion 47 is formed at a position corresponding to the straight portion of the crescent-shaped top surface portion 41. A label 61 indicating a product name, price, raw materials, etc. is affixed to the rectangular flat surface portion 47 (see FIG. 1). The label 61 may be directly attached to the rectangular flat surface portion 47, or may be attached via the wrap with the rectangular flat surface portion 47 as a base in a state where the entire packaging container 1 is wrapped with a wrap. The rectangular flat surface portion 47 is formed so as to have a width in the range of 1/5 to 1/3 (about 1/4 in the illustrated example) with respect to the entire lid 4.

The triangular surface portion 48 is formed at a position corresponding to the arc portion of the top surface portion 41 having a half-moon shape. A stepped portion 48S extending diagonally across the lid peripheral wall portion 46 is formed between the two triangular surface portions 48 adjacent to each other. Therefore, the stepped portion 48S can impart a larger resistance force to an external force, and can improve the strength of the lid body 4. Further, when the vertices of the plurality of triangular surface portions 48 all face the same circumferential direction (counterclockwise direction in the example of FIG. 3), the movement as if the entire lid peripheral wall portion 46 is swiveled. Can create a unique beauty. Therefore, the design of the lid 4 can be improved.

At the lower end of the lid peripheral wall portion 46, convex portions 49 (convex portions for blocking prevention) are formed in a plurality of locations in order to prevent the lids 4 from coming into close contact with each other when they are stacked. Has been done.

The lid flange portion 52 extends outward from the lower end portion of the lid peripheral wall portion 46. The lid flange portion 52 is overlapped with the main body flange portion 32 of the container main body 2. The lid flange portion 52 is formed in a shape corresponding to the main body flange portion 32 of the container main body 2, and has a linear extending portion 53 and an arc-shaped extending portion 54. The linear extending portion 53 is formed at a position corresponding to the rectangular flat surface portion 47. The linear extending portion 53 is arranged so as to extend along the horizontal plane in a state where the container body 2 and the lid 4 are fitted and the bottom surface portion 21 is in contact with the ground. The arc-shaped extending portion 54 is formed at a position corresponding to the plurality of triangular surface portions 48. The arc-shaped extending portion 54 is arranged so as to be inclined diagonally upward while the container body 2 and the lid 4 are fitted and the bottom surface portion 21 is in contact with the ground. Further, the arc-shaped extending portion 54 is formed so as to extend upward from both ends of the linear extending portion 53. In the present embodiment, the arc-shaped extending portion 54 corresponds to the "tilted extending portion" of the lid body 4.

In such a configuration, the height of the lid peripheral wall portion 46 is the highest on the linear extending portion 53 side (the foot portion 54b side of the inclined arc-shaped extending portion 54), and the arc-shaped extending portion 54 It gradually becomes lower toward the top 54t side (see FIG. 4). The top portion 54t is the portion that occupies the highest position in the arc-shaped extending portion 54 with the bottom surface portion 21 in contact with the ground, and the foot portion 54b is the portion that occupies the highest position in the arc-shaped extending portion 54. It is the part that occupies a low position. In the present embodiment, the top 54t of the arcuate extending portion 54 corresponds to the "maximum height portion" of the lid body 4, and the foot portion 54b corresponds to the "minimum height portion" of the lid body 4.

A hanging portion 57 is provided on the outer edge of the lid flange portion 52. The hanging portion 57 is continuously provided over the entire circumference. The vertical length of the hanging portion 57 is longer than the vertical length of the hanging portion 37 of the container body 2. Then, in the lower region of the hanging portion 57, an engaging ridge 58 projecting inward is formed along the circumferential direction. In this embodiment, a plurality of engaging ridges 58 are provided so as to be dispersed in the circumferential direction. The engaging ridge 58 engages with the lower end edge of the hanging portion 37 of the container body 2 from below with the lid 4 attached to the container body 2. That is, the packaging container 1 of the present embodiment is configured as an outer fitting type packaging container.

In the present embodiment, the lid 4 is not particularly provided with a picking piece for a picking operation when the lid is opened. Therefore, there is almost no concern that such picked pieces will be caught by other objects during transportation or display, and there is little risk of accidentally opening the lid. Further, when the entire packaging container 1 is wrapped with a wrap, the tension load applied to the wrap can be reduced, and the wrap can be made difficult to tear.

In order to open the packaging container 1 of the present embodiment, first, the container body 2 and the lid 4 are held by one hand and rotated relative to each other. Then, as shown in FIG. 7, the lid flange portion of the lid 4 is formed on one corner 35 between the linear extending portion 33 and the arc-shaped extending portion 34 in the main body flange portion 32 of the container main body 2. The linear extending portion 53 in 52 rides up, and the fitting of the container body 2 and the lid 4 over the entire circumference is partially released. However, at this point, the engaging ridge 58 is engaged with the lower end edge of the hanging portion 37 over a wide range of the main body flange portion 32 and the lid body flange portion 52, and the container main body 2 and the lid body 4 are still partially engaged. Remains mated.

In this state, as shown in FIG. 8, one corner portion 55 between the linear extending portion 53 and the arc-shaped extending portion 54 in the lid flange portion 52 of the lid 4 is a container in a plan view. It is arranged at a position protruding outward from the linear extending portion 33 in the main body flange portion 32 of the main body 2. The corner portion 55 in a state of protruding outward can exert a function as a “picking piece”. Then, by picking and lifting the protruding corner portion 55, the lid 4 that has begun to come off from the container body 2 due to the relative rotation operation can be completely removed from the container body 2. In this way, the lid opening operation can be easily performed by using the corner portion 55 of the lid body flange portion 52 of the lid body 4 as a picking piece that appears when necessary.

Alternatively, the container body 2 and the lid 4 may be further rotated relative to each other. Then, up to the corner portion 55 of the lid body flange portion 52 of the lid body 4 rides on the linear extending portion 33 of the main body flange portion 32 of the container main body 2, and the lid body 4 is completely removed from the container main body 2. It comes off. In this way, the lid opening operation can be easily performed only by rotating the container body 2 and the lid 4 relative to each other beyond a predetermined angle. Whether to pick the corner 55 of the lid flange 52 of the lid 4 or to continue the relative rotation operation between the container body 2 and the lid 4 is selected by the person who performs the operation. Just do it.

The triangular surface portions 48 formed on the lid peripheral wall portion 46 of the lid 4 all have their vertices facing the same circumferential direction, creating a dynamic aesthetic feeling as if they were turning. And, such a turning feeling suggests a rotation operation with respect to the lid body 4 for performing the lid opening operation. The person who performs the lid opening operation can easily perform the lid opening operation as described above by rotating the lid body 4 along the turning direction according to the turning feeling created by the plurality of triangular surface portions 48. Can be done.

As shown in FIGS. 9 and 10, the packaging container 1 of the present embodiment applies a display method (hereinafter, referred to as “line display”) in which a plurality of packaging containers 1 are arranged back and forth along the horizontal direction. Suitable for In the following description, one of the pair of packaging containers 1 adjacent to each other is referred to as "first packaging container 1A" and the other is referred to as "second packaging container 1B" to distinguish them. To do. Further, in the present embodiment, in particular, in the line display, the top 54t of the arc-shaped extending portion 54 of the lid 4 of the first packaging container 1A is the lid peripheral wall portion 46 of the second packaging container 1B (specifically). Specifically, it is suitable for applying a display method (hereinafter, referred to as “contact line display”; see FIG. 10) in which a rectangular flat surface portion 47) is brought into contact with the horizontal direction.

As shown in FIG. 10, when displaying the contact line, the foot portion 54b and the linear extending portion 53 of the arc-shaped extending portion 54 of the lid 4 of the second packaging container 1B are the first. It does not come into contact with the main body peripheral wall portion 26 of the packaging container 1A. In other words, the foot portion 54b and the linear extending portion 53 of the arc-shaped extending portion 54 of the second packaging container 1B have a horizontal gap with respect to the main body peripheral wall portion 26 of the first packaging container 1A. (Horizontal gap g1) is spaced apart. Further, the foot portion 54b and the linear extending portion 53 of the arc-shaped extending portion 54 of the second packaging container 1B are located below the arc-shaped extending portions 34 and 54 of the first packaging container 1A. Arranged like this. At that time, the foot portion 54b and the linear extending portion 53 of the arc-shaped extending portion 54 of the second packaging container 1B refer to the arc-shaped extending portions 34 and 54 of the first packaging container 1A. They are arranged with a vertical gap (upper and lower gap g2).

In this way, the tops 34t, 54t of the arc-shaped extending portions 34, 54 of the first packaging container 1A and the foot portions 34b, 54b of the arc-shaped extending portions 34, 54 of the second packaging container 1B. Are arranged so as to have overlapping regions L that overlap in the front-rear direction. As a result, the installation space at the time of display can be kept small by the amount that the two packaging containers 1A and 1B partially overlap each other. Therefore, the display efficiency can be improved while ensuring the visibility of the contained object.

Further, in the present embodiment, when the contact line is displayed, the foot portion 54b and the linear extending portion 53 of the arc-shaped extending portion 54 of the second packaging container 1B are formed on the peripheral wall of the main body of the first packaging container 1A. It is arranged so as to be located below the second inclined portion 26B of the portion 26.
