Description

  The present invention relates to a lid for a packaging container and a packaging container having the lid.

  In recent years, side dishes such as deep-fried chicken, potatoes, Chinese side dishes, sushi, and the like have been sold in hors d'oeuvres so that many people can eat them. In this type of container, the container itself is enlarged so that it can be eaten by a large number of people such as 4 to 6 people. In addition, the lid is required to have a performance capable of satisfactorily viewing the food as the contents so that the deliciousness of the contained food can be expressed as it is through the lid. Therefore, a structure in which ribs for reinforcement are not provided not only on the top surface portion of the lid but also on the inclined side surface portion of the lid is required, but in order to maintain the strength of the lid without the reinforcement rib, It is necessary to increase the strength by increasing the thickness of the transparent sheet material. However, if the lid sheet is thick, the lid becomes heavy and the lid itself becomes hard, which makes it difficult to open the lid fitted to the container body.

  In the following Patent Document 1, an hors d'oeuvre container provided with a partition is proposed in order to accommodate many foods such as skewers, sushi, and fried chicken. The lid used for this container has a configuration in which the lower end portion of the drooping surface portion hanging from the peripheral portion of the top surface portion and the upper end portion of the inclined side surface portion are connected. Thus, in the structure which the lower end part of the drooping lower surface part in the lid | cover and the upper end part of the inclined side surface part connected, although the visibility of the food which passed through the lid | cover is favorable, the intensity | strength of a lid | cover tends to be insufficient. Therefore, in order to ensure the strength of the lid, it is necessary to increase the thickness of the lid sheet as described above, and there is a problem that it is difficult to open the lid.

  In addition, the lid described in Patent Document 2 below is provided with two horizontal upper and lower horizontal surfaces between the hanging surface and the inclined side surface over the entire circumference. In this way, when the upper and lower horizontal plane parts are provided over the entire circumference between the vertical surface part and the inclined surface part, the strength of the lid is improved, but when trying to see the food inside through the lid from diagonally above, The upper and lower two horizontal surfaces obstruct the food visibility. Further, good visibility cannot be obtained because the inclined side surface portion is bent at the intermediate portion in the vertical direction.

  Therefore, the present invention has been made in view of the above-mentioned conventional problems, and it is possible to ensure the necessary strength without excessively increasing the thickness of the sheet, and to provide a packaging container lid with excellent contents visibility. It is an object to provide a packaging container provided with the lid.

The present invention has been made to solve the above-mentioned problems, and the lid of the packaging container according to the present invention is made of a transparent synthetic resin sheet and is configured to fit the container body. A polygonal planar top surface portion, a drooping bottom surface portion that hangs downward from the entire periphery of the peripheral portion of the top surface portion, an inclined side surface portion that is inclined downward and outward, and A flange portion extending outward from the inclined side surface portion, and a lower end portion of the drooping surface portion and an upper end portion of the inclined side surface portion are connected via a horizontal plane portion extending in a horizontal direction, and the width of the horizontal plane portion is The at least one side of the polygonal shape is gradually narrowed from both corners to the center of the side, the inclined side surface is curved so as to bulge outward from the upper end to the lower end, and the inclined side is characterized in that it smoothly continuous over the

  In the lid of the packaging container having such a structure, a horizontal plane portion is provided between the lower end portion of the drooping lower surface portion and the upper end portion of the inclined side surface portion, and the horizontal plane portion is wide at the corner portion. Even if it is not a thick sheet, the strength can be easily secured. Accordingly, even when containers with lids containing food as contents are stacked, the lid can be prevented from being deformed and a stable stacking state can be obtained. Moreover, since it is not necessary to use a thick sheet, the phenomenon that the lid is difficult to open is unlikely to occur. On the other hand, since the width of the horizontal plane portion is gradually narrowed from both corners to the center of the side in at least one side of the polygonal shape, it is possible to minimize a reduction in visibility at the center of the side. Therefore, the deliciousness of food can be accurately conveyed to consumers through vision.

  In particular, when the polygonal shape is a rectangular shape, it is preferable that the width of the horizontal plane portion is gradually narrowed from both corners to the central portion of the pair of long sides of the rectangular shape. The long side has a greater influence on the visibility of the food than the short side. Therefore, when the width of the horizontal plane portion is gradually narrowed from both corners to the center of the side in the pair of long sides, the food can be accurately visually recognized from the vicinity of the side center of the pair of long sides. In addition, about a pair of short side of a rectangular shape, the width | variety of a horizontal surface part may be fixed, and it may become narrow gradually from both corners to a side center part similarly to a pair of long side.

  Moreover, in the said center part, it is preferable that the horizontal plane part does not exist substantially, and it is preferable that the lower end part of a drooping surface part and the upper end part of an inclined side part are directly connected, and the visibility in a side center part is improved further. be able to.

  The packaging container according to the present invention is a packaging container comprising a container body and a lid having the above-described configuration, and the bottom surface of the bottom surface portion of the container body has a lid when the packaging containers are stacked. An engaging portion is formed which engages with the drooping bottom surface portion to prevent horizontal displacement between the packaging containers.

  As described above, since the horizontal plane portion is provided between the lower end portion of the drooping bottom surface portion and the upper end portion of the inclined side surface portion, and the horizontal plane portion is formed wide at the corner portion, the strength of the lid is easy. Can withstand the load during stacking. Therefore, it is not necessary to increase the sheet thickness excessively, and the strength can be ensured even with a thin sheet. Therefore, it is not difficult to open the lid when the lid is opened. In addition, since the width of the horizontal plane portion is gradually narrowed from both corners to the center of the side, good visibility is secured in the vicinity of the center of the side, and the deliciousness of the food, which is the contents, is accurately confirmed to the consumer through vision. I can tell you.

The height of the partition wall 13 is preferably higher than the height of the upper end portion of the main body side surface portion 11 or the upper surface of the main body flange portion 12.

  A leg portion 15 may be provided projecting downward from the peripheral edge portion of the bottom surface of the bottom surface portion 10. The shape and arrangement of the leg portion 15 are arbitrary, and the leg portion 15 may be formed along the peripheral edge, for example, over the entire circumference, or four of the bottom surface portion 10 as shown in FIGS. The leg portions 15 may be formed, for example, in an L shape in a bottom view, independently of each of the corner portions. The convex shape toward the lower side of the leg portion 15 corresponds to the concave shape of the groove 14 of the bottom surface portion 10.

  When the leg portion 15 is protruded from the lower surface of the bottom surface portion 10, the lower surface of the leg portion 15 comes into contact with the placement surface when the container body 1 is placed on the placement surface such as a flat table. In FIG. 8, a large number of dots are attached to the lower surface of the leg portion 15 which is a portion that comes into contact with the placement surface. Further, when the leg portion 15 is protruded on the lower surface of the bottom surface portion 10, the legs 15 of the upper container body 1 are placed on the lower lid when the closed containers are stacked as shown in FIG. 9. It is preferable to abut against the upper part of the two inclined side surface parts 22 or to face each other through a slight gap, thereby preventing horizontal displacement between containers.

  A region inside the leg portion 15 of the bottom surface of the bottom surface portion 10 may be recessed so as to gradually become deeper from the peripheral edge portion to the center portion corresponding to the bulging shape of the bottom surface portion 10 above the top surface. . In that case, when the containers in the closed state are stacked, the top of the lid 2 of the lower container is placed on the peripheral portion close to the leg portion 15 in the region inside the leg portion 15 of the bottom surface 10. It is preferable that a supporting convex portion 16 that contacts the upper surface of the surface portion 20 is formed. In FIG. 8, the outer edge of the top surface portion 20 of the lid 2 and the hanging surface portion 21 are indicated by a two-dot chain line. Although the area | region inside the leg part 15 is curving shape among the lower surfaces of the bottom face part 10, the lower surface 16a of the convex part 16 for support is a flat surface. As shown in FIG. 9A, the lower surface 16a of the supporting convex portion 16 abuts against the upper surface of the peripheral portion of the top surface portion 20 of the lower lid 2 during stacking. The lower surface 16 a of the supporting convex portion 16 is located higher than the lower surface of the leg portion 15. A plurality of supporting convex portions 16 are preferably formed at intervals, and in this embodiment, a total of four portions are formed, one for each side.

  An engagement convex portion as an engagement portion is provided on the lower surface of the bottom surface portion 10 and inside the leg portion 15 in order to prevent horizontal displacement when the closed containers are stacked. It is preferable that 17 projects in an island shape. It is preferable that the engagement convex part 17 is comprised and arrange | positioned so that position shift of the vertical and horizontal two directions of a container can be prevented. Specifically, it is preferable that the engagement protrusions 17 are provided at a total of four locations, one for each side. The engaging convex portion 17 is disposed in the vicinity of the inner side of the leg portion 15 and is located on the outer side of the supporting convex portion 16, and the engaging convex portion 17 and the supporting convex portion 16 are either in the vertical direction or in the horizontal direction. The position is shifted in the direction. As shown in FIGS. 8 and 9B, the engaging convex portion 17 is positioned outside the hanging surface portion 21 of the lower lid 2 when stacked, and the inner side surface 17 a of the engaging convex portion 17 is the lower lid 2. It abuts on the hanging surface 21 from the outside or confronts it through a slight gap. Accordingly, the hanging lower surface portion 21 of the lower lid 2 is positioned so as to be engaged with the inside of the four engaging convex portions 17 when stacked, and the vertical and horizontal directions of the container are formed by the four engaging convex portions 17. Is prevented from being displaced. Note that the engaging convex portion 17 is located higher than the lower surface of the leg portion 15.

  Although the shape and configuration of the main body flange portion 12 may be various, it may be a ball shape with the upper surface curved upward, or may be decorated by providing irregularities on the upper surface. In that case, you may decorate the lid flange part 23 of the lid | cover 2 mentioned later by giving an unevenness | corrugation etc. corresponding to the main body flange part 12. FIG. Moreover, it is preferable that the main body edge part 18 is formed in the outermost periphery part of the main body flange part 12 over the perimeter. The main body edge portion 18 is a portion that becomes an outer edge of the main body flange portion 12, and preferably extends substantially horizontally toward the outside.

  The main body flange portion 12 can be provided with a fitting structure with the lid 2 and may be an inner fitting structure. In this embodiment, the lid flange portion 23 covers the outside of the main body flange portion 12. Structure is adopted. In the closed state, the locking protrusion 25 formed on the inner surface of the cover flange portion 23 is locked to the lower side of the main body edge portion 18.

<Lid 2>
Next, the configuration of the lid 2 will be described. The lid 2 is formed in a plan view shape corresponding to the container body 1 and, as described above, in the present embodiment, the container body 1 has a rectangular shape in plan view. Accordingly, the lid 2 also has a rectangular shape in plan view. It has become. The lid 2 is formed on the top surface 20, the hanging surface 21 that hangs down from the peripheral edge of the ceiling 20 at an angle close to the lower side, and the outside of the hanging surface 21, and is inclined downward and outward. And an inclined side surface portion 22 that extends and a lid flange portion 23 that extends outward from the lower end portion of the inclined side surface portion 22.

  The top surface portion 20 is a flat surface and is formed of a flat smooth surface without irregularities such as ribs. The top surface portion 20 is a horizontal plane and has a rectangular shape in plan view, and has corners that are four sides and four vertices, and the four sides face each other with a pair of long sides facing each other. It consists of a pair of short sides. Each side may be curved to bulge outward. The drooping surface portion 21 is formed to have a substantially constant height over the entire circumference. Therefore, the height of the lower end portion of the drooping surface portion 21 is substantially constant over the entire circumference.

  A horizontal surface portion 24 extending in the horizontal direction is formed between the hanging lower surface portion 21 and the inclined side surface portion 22. A horizontal plane portion 24 is formed between the lower end portion of the drooping surface portion 21 and the upper end portion of the inclined side surface portion 22, and the lower end portion of the drooping surface portion 21 and the upper end portion of the inclined side surface portion 22 are connected via the horizontal plane portion 24. Has been. The horizontal surface portion 24 extends outward from the lower end portion of the drooping surface portion 21, and therefore, the inner edge portion of the horizontal surface portion 24 becomes the lower end portion of the drooping surface portion 21, and the outer edge portion of the horizontal surface portion 24 is the upper end of the inclined side surface portion 22. Part.

  The horizontal surface portion 24 is not constant in width over the entire circumference. The horizontal surface portion 24 is not substantially constant in width at least on a pair of long sides, and the width changes. In the present embodiment, the horizontal plane portion 24 has a substantially constant width on the pair of short sides, but the width may also change on the pair of short sides in the same manner as the pair of long sides. In the pair of long sides, the horizontal surface portion 24 is the widest at both corners, and the width gradually decreases from both corners to the center of the side. In the present embodiment, the width of the horizontal plane portion 24 is substantially zero at the center portion of the pair of long sides, and the horizontal plane portion 24 is substantially present at the center portion of the pair of long sides. No connection 26 is provided. Therefore, in the connection portion 26, the drooping surface portion 21 and the inclined side surface portion 22 are directly connected without passing through the horizontal surface portion 24, and the lower end portion of the drooping bottom surface portion 21 is the upper end portion of the inclined side surface portion 22. . The connection portion 26 which is a region where the horizontal surface portion 24 does not substantially exist in the central portion of the long side may be a single point, but may have a predetermined length as in this embodiment, and the length The length may be about several centimeters, and may be about 1/3 of the long side, for example. In addition, the horizontal surface part 24 may remain in a predetermined width without disappearing in the center part of the side of the pair of long sides.

  The inclined side surface portion 22 may have a gently curved shape so as to bulge outward from its upper end portion to its lower end portion. In addition, the inclined side surface portion 22 is curved so as to bulge outward along the horizontal direction at each corner, and in this embodiment, also bulges outward along the horizontal direction at each side portion. The curvature radius may be large at each side and small at each corner. In any case, it is preferable that the inclined side surface portion 22 has a surface configuration that is smoothly continuous over the entire circumference. Thus, most of the inclined side surface portion 22 is constituted by a smooth surface having no irregularities such as ribs.

  At the lower end portion of the inclined side surface portion 22, a blocking prevention convex portion 27 is formed to prevent a phenomenon (blocking phenomenon) that the lids 2 are tightly fitted to each other when the lids 2 are overlapped with each other. It is preferable. When the anti-blocking convex portion 27 is provided, the entire area of the inclined side surface portion 22 excluding the anti-blocking convex portion 27 is preferably a smooth surface having no irregularities. The arrangement of the anti-blocking convex portions 27 is not equal, and is formed so as to shift the position of each lid 2 in the circumferential direction. The container main body 1 may also be provided with a similar blocking preventing convex portion.

  A lid flange portion 23 extends from the lower end portion of the inclined side surface portion 22 toward the outside. The lid flange portion 23 is located from the upper side to the outer side of the main body flange portion 12 in the closed state. Specifically, the lid flange portion 23 includes a flange upper surface portion 231 that extends substantially horizontally outward from the lower end portion of the inclined side surface portion 22, and an outer edge portion of the flange upper surface portion 231 toward the lower side as a whole. A skirt portion 232 that extends while inclining outward may be provided. Moreover, it is preferable that the cover rim | edge part 233 is provided in the outer side of the skirt part 232 over the perimeter.

  In the closed state, the flange upper surface portion 231 is positioned opposite to the upper side of the main body flange portion 12, and the skirt portion 232 is positioned outside the main body flange portion 12. The flange upper surface portion 231 may be decorated by providing irregularities or the like. As described above, when the main surface flange portion 12 is provided with irregularities or the like, the flange upper surface portion 231 and the skirt portion 232 are correspondingly provided. Concavities and convexities may be provided. A locking projection 25 protrudes inward from the inner surface of the lower portion of the skirt portion 232, and the locking projection 25 is locked to the lower side of the main body edge portion 18 in the closed state.

  At least the outer peripheral edge side of the main body rim portion 18 and the lid rim portion 233 may be formed with a large number of fine irregularities to reinforce and prevent the fingers from being cut even if they hit the fingers. The irregularities have a wave shape when viewed from the front, and a number of peaks and valleys are formed short in the width direction at each side, and are formed along the radial direction of emission at the corners. Is done. Further, for example, the irregularities are formed by knurled eyes such as flat knurled eyes and twill knurled eyes, and are preferably formed by twill knurled eyes so as not to slip.

  The container body 1 and the lid 2 are formed by so-called sheet molding. Examples of sheet forming include vacuum forming, pressure forming, vacuum pressure forming, double-sided vacuum forming, hot plate forming, and the like. In any case, the sheet is formed by thermoforming a synthetic resin sheet. The synthetic resin sheet is made of, for example, a styrene resin such as polyethylene terephthalate or polystyrene, or an olefin resin such as polypropylene or polyethylene. In particular, a transparent cover is used. A transparent sheet may also be used for the container body 1. In addition, a stretched sheet obtained by appropriately stretching these sheets is a more preferable sheet material because it can improve heat resistance and strength while ensuring transparency.

  In addition to these materials, the container body 1 can be made of a material that is not transparent, for example, a sheet in which the aforementioned synthetic resin is filled with an inorganic material, or a foamed sheet obtained by foaming these sheet materials. It may be a foamed polystyrene sheet obtained by foaming polystyrene, or a heat-resistant foamed styrene resin sheet using a styrene-based resin with improved heat resistance containing polyphenylene ether having excellent heat resistance as polystyrene. . Furthermore, it is also possible to use a laminated sheet obtained by printing a foam sheet or laminating a plain resin film on one side or both sides.

  The container made as described above is closed by fitting the lid 2 to the container body 1 after the contents are accommodated. Since the lid 2 is transparent, the contents can be easily visually recognized through the region from the top surface portion 20 to the inclined side surface portion 22 of the lid 2. Since the top surface portion 20 is a flat smooth surface without unevenness, and the inclined side surface portion 22 is also a smooth surface without unevenness except for the anti-blocking convex portion 27, the state of contents not only from above but also from obliquely above Can be seen accurately. Moreover, since the width of the horizontal surface portion 24 is gradually narrowed from both corners to the center portion of the pair of long sides, good visibility can be obtained even in the portion between the top surface portion and the inclined side surface portion 22 on the long side. It can be secured. Since one of the pair of long sides is often directed to the front, it is excellent in visibility when the container is viewed from the front side at the storefront. In particular, when the horizontal surface portion 24 substantially disappears in the center portion of the pair of long sides and the drooping surface portion 21 and the inclined side surface portion 22 are directly connected, the visibility in the center portion of the side can be further improved. . Furthermore, when the connecting portion 26 in which the hanging lower surface portion 21 and the inclined side surface portion 22 are directly connected in the central portion of the side has a predetermined length in the horizontal direction, the visibility in the central portion of the side is further improved. Can be seen more clearly. Therefore, the deliciousness of food can be accurately conveyed to consumers through vision.

  On the other hand, since the width of the horizontal surface portion 24 is narrow at the central portion of the side but wide at the corner portion, the required strength can be easily ensured. In addition, when the horizontal surface part 24 is formed with a substantially constant width on the pair of short sides, the strength can be more easily ensured. Thus, by providing the horizontal surface portion 24 and making it wide at each corner, it is possible to prevent deformation of the lid 2 even when a load is applied to the lid 2 from above when containers containing food are stacked, and stable. A stacked state is obtained. That is, the strength against the stacked load is ensured mainly at the four corners. Therefore, it is not necessary to use an excessively thick sheet, and the necessary strength can be ensured with a thin sheet. Therefore, the phenomenon that the lid 2 is difficult to open from the container body 1 when the lid is opened is unlikely to occur. Further, since the horizontal plane portion 24 is narrow or substantially not present in the center portion of the pair of long sides, the load is released even if the vicinity of the center portion is deformed by the load during stacking. As soon as the shape is restored.

  In the present embodiment, the container having a rectangular shape in plan view has been described, but a container having a square shape in plan view may be used. FIG. 10 shows the container lid 2 having a square shape in plan view. In the case of the square lid 2, it is preferable that the horizontal surface portion 24 is gradually narrowed from both corners to the center of each of the four sides.
