Description

  The present invention relates to a packaging container, and more particularly, to a container suitable for storing and selling items such as nigiri sushi.

  Conventionally, for example, packaging containers used for storing and selling take-out sushi at convenience stores, supermarkets, department stores, etc. are generally rectangular containers with a generally flat bottom that is thermoformed from a synthetic resin sheet. The main body and the upper surface, which is also thermoformed from a synthetic resin sheet, are substantially flat and transparent. The sushi is arranged on the container main body at a predetermined interval, and then covered with the cover.

  The container body as described above is generally beautifully printed, the inner surface of the lid is anti-fogging treated, and when the sushi is put in a refrigerated display case, the water vapor evaporated from the sushi is granular. This prevents the lid from fogging and the interior from becoming invisible. In addition, the surface of the container body is often provided with fine irregularities to increase the friction so that sushi does not slip even a little.

  On the other hand, it is not possible to prevent sushi from coming off due to vibrations such as when taking it home only by such unevenness of the anti-slip. Patent Documents 1 and 2 are known to improve this.

  Patent Document 1 describes that sushi is prevented from approaching by providing an edge of 5 mm or less around the container stand.

  In Patent Document 2, in order to individually store sushi, a plurality of shallow concave portions having a substantially rectangular shape with an open top surface formed in a size that fits almost the lower part of the sushi are formed in the container body. A flat, substantially rectangular recess having an opening on the lower surface side that covers the upper part of the sushi contained in the recess is formed in the lid, and at least a side surface substantially parallel to the longitudinal direction of the recess of the lid is accommodated in the recess of the container body. It is described that it is configured to be located near the side surface of sushi to prevent sushi from approaching.

  However, if an edge portion of 5 mm or less is provided around the container stand as in Patent Document 1, sushi may roll over and cannot be prevented sufficiently. On the other hand, when the depth of the edge is increased, it becomes difficult for the worker to house the sushi, and it becomes difficult for the consumer to take out the sushi. The taste and freshness of the contained sushi will not be appealed because the sushi is felt to have sunk.

  In addition, as in Patent Document 2, in a configuration in which a recess is provided in the container body for individually storing sushi, and a side surface substantially parallel to at least the longitudinal direction of the recess is provided on the lid, the operator stores sushi. It is difficult for consumers to take out sushi, and since the lid is also provided with a side surface substantially parallel to at least the longitudinal direction of the recess, it becomes difficult to visually recognize the contained sushi. The deliciousness and freshness cannot be appealed, which in turn reduces the consumer's willingness to purchase.

  Therefore, the present invention is a highly transparent lid, and is a packaging container suitable for the use of a lid that is excellent in visibility of accommodated items such as stored sushi. The deliciousness of the containment that prevents the containment from being felt as if the contained containment has been sunk, while preventing the containment from being easily carried out and taking out the containment. It is another object of the present invention to provide a packaging container that can appeal for freshness.

  The inventors of the present invention use a lid that solves the above-mentioned problems and is highly transparent so that the deliciousness and freshness of the contained items such as sushi can be appealed, and has excellent visibility of the contained items. At the same time, they have intensively studied suitable packaging containers. A container that has sufficient strength that is difficult to bend, prevents the contents from rolling and prevents the object from being offset, facilitates the work of accommodating the contents, and facilitates the removal of the contents. The present invention was completed by earnestly studying the above.

The present invention substantially comprises a contained object mounting portion constituted by a flat surface on the container body, outside the periphery of the contained object placing section, Ri Na provided partially different peripheral wall heights A projecting portion that circulates around the periphery of the container body, and the accommodation object placing portion is provided inside the projecting portion, and the accommodation object placement is provided between the projecting portion and the peripheral wall. parts is a packaging container, characterized in Rukoto such provided with a leg to position the upward.

  According to this configuration, the stored items such as sushi can be arranged with good appearance by the stored item mounting portion configured with a substantially flat surface. And, by providing peripheral walls with partially different heights, it is possible to effectively prevent the contained articles from rolling or offset in the high part of the peripheral wall, and in the low part Therefore, it is possible to easily carry out the work of containing the stored item and to easily take out the stored item. Further, unlike the case where a high peripheral wall is provided as a whole, there is no feeling (sinking feeling) that the contained object feels depressed.

In addition , the protrusion and the peripheral wall partially provide a double protrusion on the peripheral edge of the container body, and the container itself bends due to its weight even if the container contains the container. It is possible to prevent dripping.

In addition , the contents placing portion can be positioned upward by the legs, and the prevention of the “sinking feeling” can be more effectively exhibited.

  According to the present invention, it is a highly transparent lid, and is a packaging container suitable for the use of a lid that is excellent in visibility of contained items such as sushi. The deliciousness of the containment that prevents the containment from being felt as if the contained containment has been sunk, while preventing the containment from being easily carried out and taking out the containment. In addition, a packaging container that can appeal for freshness can be provided.

It is a perspective view which shows the container main body and lid body of this embodiment. It is a top view of the container main body of this embodiment. It is the perspective view seen from the bottom face side of the container main body of this embodiment. It is sectional drawing in the AA cross section (FIG. 2) of the container main body of this embodiment.

  Next, the present invention will be described by taking up one embodiment. In addition, the expression of the up-down direction among the expressions of the direction in the following description is in the state in which the accommodation (nigiri sushi) can be mounted in the packaging container. In addition, the expression of the inside and outside directions is in a plan view.

  The packaging container of this embodiment is a combination of a container body 1 and a lid 2. In the present embodiment, a packaging container for nigiri sushi (hereinafter simply referred to as “sushi”) will be described.

  In the present embodiment, the planar view shape of the peripheral edge of the container body 1 and the lid body 2 is substantially rectangular, but the peripheral edge is curved as shown in FIG. The shape of the container body 1 and the lid body 2 is not limited to this, and can be implemented in various shapes. Moreover, in this embodiment, eight (running) sushi can be arranged in two rows in an oblique direction, but various shapes can be used according to the situation in which the items are arranged, for example, the arrangement is one row. Can be implemented.

  The peripheral edges of the container main body 1 and the lid body 2 are subjected to fine unevenness processing and embossing by molding, so that they are not outer edge lines of waveforms (sine wave, triangular wave, trapezoidal wave, etc.) in side view, that is, not straight lines. It is desirable to provide an outer edge line (not shown). Thereby, since the edge of the periphery in the container main body 1 and the cover body 2 becomes sharp, the fingertip at the time of touching the packaging container or opening and closing the cover body 2 can be protected, for example. Further, the strength of the peripheral edge is increased, and there is an effect of preventing the packaging container from being broken.

  The packaging container of the present embodiment can be obtained by thermoforming a resin sheet, particularly a foamed sheet, and a foamed layer in which a resin film is laminated on one or both sides of the foamed sheet. A laminated resin sheet having a surface film layer can also be used.

  The resin sheet is not particularly limited, and conventionally known ones can be used. For example, a styrene resin alone, a copolymer resin of a monomer such as butadiene, maleic anhydride, α-methyl / styrene, methacrylic acid, and the like that can be copolymerized with a styrene monomer, or a styrene resin and the above copolymer Mixtures with heat-resistant resins such as coalesced resins and polyphenylene ether resins, polypropylene resins, polyethylene terephthalate resins, etc., and physical foaming agents such as butane and pentane, and chemical foaming such as azodicarbonamide on these resins And a foamed sheet obtained by kneading with an extruder together with a foaming agent such as an agent, carbon dioxide, nitrogen, air, etc. and extruding and foaming, or a resin film laminated on one or both sides thereof.

  The resin film laminated on one side or both sides of this foam sheet is, for example, a film made of styrene resin such as polystyrene resin, high impact polystyrene resin, heat resistant polystyrene resin, polyethylene resin, polypropylene resin, etc. A film made of a polyolefin resin, a film made of a polyester resin such as a polyethylene terephthalate resin, a film made of a resin having an excellent gas barrier property such as a polyvinyl alcohol resin or a polyvinylidene chloride resin is used independently. be able to.

  Alternatively, it can be used as a film in which these films are laminated (laminated film) or a resin film in which these laminated films are laminated on a foam sheet. In particular, when using a film made of a styrene resin or a copolymer resin used for a foam sheet, the whole is made of the same material, and the recyclability of the packaging container can be improved. This is preferable in terms of points.

  When used for forming a container main body of a packaging container for containing food or the like like the container main body 1 of the present embodiment, a foam layer is usually formed to a thickness of 1 to 5 mm by the foam sheet. It is preferable to use a resin sheet formed and having a surface film layer formed in any thickness of 3 μm to 500 μm by the resin film.

  In addition, as long as it is a resin sheet provided with the foam layer, formation of the container main body which concerns on this embodiment can employ | adopt various things, without being limited to the resin sheet of the said illustration, A surface film It is also possible to employ one composed only of a foam layer not having a layer, one having a surface film layer formed on both sides via the foam layer, and the like.

  On the upper surface of the container main body 1 formed by thermoforming the resin sheet as described above, the contents placing portion 11, the peripheral wall 12, and the protruding portion 13 are formed in this order from the inner side toward the peripheral edge. Yes. And the leg part 14 is formed so that it may protrude below. In the portion where the leg portion 14 is provided, the leg portion 14 is provided between the peripheral wall 12 and the protruding portion 13.

  The accommodation object mounting portion 11 is configured by a substantially flat surface. The storage unit 11 according to the present embodiment has a shape that allows nigiri sushi to be adjacent to each other in an oblique direction, and can be arranged in a total of 8 (through) in 2 rows in 4 rows (through). Has been. Since the contents placing portion 11 is configured with a substantially flat surface, the sushi can be arranged with good appearance. In addition, the peripheral edge 11a in the accommodation object mounting part 11 is defined by the peripheral wall 12 except for a part (a position where only the leg part 14 is formed). And the small protrusion 111 and the large protrusion 112 are provided in the position which corresponds to the boundary of several sushi in the accommodation thing mounting part 11. As shown in FIG.

  The small protrusions 111 are provided along the long sides of the sushi arranged on the storage object placement unit 11. The small protrusions 111 are used as an indication of the position at which the worker arranges sushi on the stored item placement unit 11 at a site where sushi is arranged (such as a backyard of a food factory or a retail store). In addition, it can also act as a sushi stopper. In the present embodiment, it is formed as a linear ridge that slightly protrudes upward from the surface of the storage unit 11, but it mainly serves as an indication of the position, so the shape is There is no particular limitation. For example, it may be a broken line-like protrusion or a concave line. Moreover, you may provide only a pattern by printing etc., without forming an unevenness | corrugation.

  The large protrusions 112 are provided so as to be orthogonal to the small protrusions 111, that is, along the short sides of the sushi arranged in the stored item placement unit 11. The large protrusion 112 according to the present embodiment is formed so as to protrude larger from the surface of the stored object placement portion 11 than the small protrusion 111. The large protrusion 112 is used as a measure of the position at which the operator places sushi on the stored item placement portion 11, as with the small protrusion 111. Further, together with the peripheral wall 12, the effect of preventing the sushi from shifting in the longitudinal direction is exhibited.

  A large protrusion recess 112 a is formed in the center of the large protrusion 112 in the longitudinal direction. In the present embodiment, the container body 1 is provided so as to be along the longitudinal direction of the container body 1 at the substantially center of the container body 1 in the width direction. In this large protrusion recess 112a, a sheet made of resin or the like for partitioning the contents (sushi in the present embodiment) called “balun” can be arranged. When the “balun” is first arranged in the large protrusion recess 112a and then sushi is arranged on the storage unit 11, the “balun” can be curved and arranged between the two rows of sushi. . Therefore, the “balun” can be beautifully arranged. Further, this “balun” can more effectively prevent sushi from being displaced on the contents placing portion 11.

  The peripheral wall 12 is provided on the outer side of the peripheral edge 11a in the stored article placement portion 11, and in the present embodiment, a plurality of parts having partially different heights are provided. The peripheral wall 12 of this embodiment is comprised from the continuous wall 121 and the independent wall 122, as shown in FIG.1 and FIG.2, and as shown in FIG. It has been launched as a starting point.

  The continuous wall 121 is provided in a portion of the peripheral edge 11a of the accommodation object placing portion 11 excluding a short leg portion 142 (described later). As shown in FIG. 4, the cross-sectional shape of the continuous wall 121 is suddenly raised from the container placement unit 11 side toward the peripheral edge of the container body 1, and gradually falls after the top part is exceeded. ing. And this continuous wall 121 is so that the ridgeline of a top part may wave in the direction in alignment with the peripheral edge 11a in the thing mounting part 11, ie, so that it may rise and fall alternately in the same direction (the height from the thing mounting part 11). Are formed partially different). Illustrated in FIG. 2, the high portions 121H and the low portions 121L are alternately formed.

  The independent wall 122 is a portion where the continuous wall 121 is interrupted, and is provided at a position closer to the inside of the short leg portion 142 (described later). Similarly to the continuous wall 121, the sectional shape of the independent wall 122 is suddenly raised from the container placement unit 11 side toward the peripheral edge of the container main body 1 and gradually falls over the top. Has been. And this independent wall 122 is formed so that the ridgeline of a top part may become the highest in the center in the direction in alignment with the peripheral edge 11a in the stored article mounting part 11. FIG. In the present embodiment, it is assumed that the stored object placement portion 11 is also present between the independent wall 122 and the continuous wall 121.

  The sushi arranged in the storage unit 11 is surrounded by the continuous wall 121 and the independent wall 122. Thereby, it is possible to effectively prevent sushi from rolling or leaning at a high portion (high portion 121H) in the continuous wall 121. And the independent wall 122 also has the effect | action which prevents that sushi rolls or offsets. On the other hand, in the portion of the continuous wall 121 where the height is low (the low portion 121L) and the portion where the independent wall 122 and the continuous wall 121 are not raised at all, it is easy for the operator to store sushi. And it can make it easy for consumers to take out sushi. In addition, in this embodiment, the above-mentioned accommodation operation | work and taking-out can be made still easier because it is provided so that the said low part may substantially correspond to the corner | angular part of the sushi arrange | positioned.

  Here, when a high peripheral wall is provided as a whole, the lower part of the sushi is concealed by this high peripheral wall, giving the consumer the feeling that the sushi has subsided (sinking feeling). However, in this embodiment, since the low part (low part 121L) exists in the continuous wall 121, and the rate at which sushi is exposed increases, such a “sink feeling” is given to the consumer. Can be prevented.

  The protruding portion 13 is provided so as to go around the entire periphery of the peripheral edge of the container body 1. The stored object placing portion 11 is provided inside the protruding portion 13 and the peripheral wall 12. As shown in FIG. 4, the cross-sectional shape of the protruding portion 13 is an upward ridge formed continuously from the continuous wall 121 or the leg portion 14 in the peripheral wall 12. As described above, the peripheral edge of the protruding portion 13 is provided with an outer edge line that is not a straight line, and the edge is not sharp.

  By providing the protrusion 13 in addition to the peripheral wall 12, the peripheral edge of the container body 1 is partially provided with a double protrusion, whereby the rigidity of the container body 1 is increased. Can be increased. Specifically, the rigidity is improved by combining the peripheral wall 12 of the container body 1 with the continuous wall 121 of the peripheral wall 12 and the protruding portion 13 in a certain section, and in a certain section different from the above, Each of the continuous wall 121 of the wall 12, the long leg 141 of the leg 14, and the protruding part 13 is combined. Thereby, even if it is a case where a thin resin sheet is used for weight reduction, it can prevent that container main body 1 itself bends with the weight of the sushi accommodated in the thing mounting part 11. FIG.

  The leg portion 14 protrudes downward while the protruding portion 13 and the peripheral wall 12 protrude upward on the basis of the object placement portion 11.

  The leg portion 14 of this embodiment includes a long leg portion 141 and a short leg portion 142. As shown in FIGS. 2 and 3, a long leg 141 is provided over most of the short side and part of the long side across one corner of the container body 1 having a substantially rectangular shape in plan view. It has been. A short leg 142 is provided on a part of the long side of the container body 1. Two long legs 141 and two short legs 142 are provided. By providing the leg portions 14 in this manner, the stored matter placement portion 11 can be positioned upward, and the prevention of the “sinking feeling” can be more effectively exhibited.

  As shown in FIG. 3, a recess 141 a is formed in the long leg 141. Here, when the consumer or the like lifts the packaging container, a finger of the consumer or the like can enter to facilitate the lifting.

  The lid body 2 is as shown in FIG. 1, and the peripheral edge portion 21 can be attached to the peripheral edge of the container body 1 by fitting. The peripheral edge of the peripheral portion 21 is also provided with an outer edge line that is not a straight line as described above, and this edge is not sharp.

  A lid center portion 22 is provided at the center of the lid body 2 in plan view. When the lid body 2 is attached to the container main body 1, the lid center portion 22 is positioned so as to cover the upper portion of the stored item placement portion 11. The top portion 221 of the lid central portion 22 is formed in a flat plate shape, and the side portion 222 is also formed in a flat plate shape except for a rib 222a that is provided at least for ensuring strength.

  Here, in the lid body in which a concave portion covering the upper part of the accommodated sushi described in Patent Document 2 is formed, the corner of the concave portion, a bent portion, or the like may obstruct the sushi from the outside. is there. On the other hand, in the lid body 2 of the present embodiment, since most of the plate body is flat, transparency is high so that the deliciousness and freshness of the sushi arranged in the storage unit 11 can be appealed to consumers. And the visibility of sushi is excellent.

  Moreover, in this embodiment, the top part 221 is made into flat plate shape, and the planar view dimension of the top part 221 can be fitted inside the leg part 14 (the long leg part 141 and the short leg part 142). It is said that. Thereby, it is possible to stack a plurality of packaging containers, and the stacking containers can be reliably stacked while preventing a shift between the packaging containers.

  As mentioned above, the packaging container of this embodiment is highly transparent so that the deliciousness and freshness of the contained sushi can be appealed, and the packaging container suitable for the use of the lid having excellent visibility of the contained sushi. In addition, it has sufficient strength that is difficult to bend, and the sushi does not roll and prevents the sushi from moving, and it is easy to accommodate the sushi and to take out the sushi. Moreover, the deliciousness and freshness of the contained items that prevent the contained items such as contained sushi from sinking can be appealed.
