[Modes for carrying out the invention]

[0008] The manufacturing methods for the containers and food packaging related to this disclosure will be described in detail below based on the attached drawings. In this specification, as shown in each figure, the X-axis, Y-axis, and Z-axis are defined, and the +Y direction is also referred to as the "back side", the -Y direction as the "front side", the +Z direction as the "upper side" or "upwards", the -Z direction as the "lower side" or "downwards", the direction along the X-axis as the "longitudinal direction" or "width direction", the direction along the Y-axis as the "short side" or "depth direction", and the direction along the Z-axis as the "height direction". Depending on the context, the -Z direction is also referred to as the "back side".

[0009] [container] (overview) First, an overview of the wrap packaging container 100 according to this disclosure will be described with reference to the drawings. Figure 1 is a top perspective view of the wrap packaging container. Figure 2 is a bottom perspective view of the wrap packaging container. Figure 3 is a top view (Figure 3(a)) and a bottom view (Figure 3(b)) of the wrap packaging container. Figure 4 is a cross-sectional view taken along line A-A' in Figure 3(a).

[0010] The wrap packaging container 100 is a deformed object made by deforming a sheet material or plate material in the thickness direction, and is used after being wrapped in wrap. As shown in Figures 1 to 3(b), the wrap packaging container 100 comprises a container body 10 that is substantially rectangular (particularly substantially rectangular) when viewed from above. As shown in Figure 1, etc., the container body 10 has a storage space 1 for storing contents through an opening 1a that is open upward (+Z direction). The contents are, for example, food. Also, as shown in Figure 2, etc., the container body 10 has a wrap storage section 2 on its lower side (-Z direction). The wrap storage section 2 is a space for storing the overlapping wrap section formed by overlapping wrap that has been placed over the container body 10 from above and then folded downward.

[0011] Traditionally, containers that use plastic wrap instead of a lid, or in addition to a lid, have been used for reasons such as ease of packaging products in stores and low cost. When using plastic wrap, the wrap is placed over the container from the top (opening side), folded downwards, and the wrap is overlapped at the bottom of the container to form a wrap overlap. Then, the wrap overlap is usually heated by bringing it into contact with a heater to cause the wrap to adhere tightly (fuse). In the overlapping section of the plastic wrap, the more layers of wrap are overlapped, the higher the adhesion between them. However, if the thickness of the overlapping section of the plastic wrap is too great, it may protrude from the bottom of the container. The inventors faced the problem that this reduces the stability of the container when it is displayed, and consequently makes it impossible to maintain the display state. Furthermore, they discovered that the protruding overlapping section of plastic wrap causes the container to tilt, making it impossible to display it nicely, and that the liquid contained inside the container may leak out of the container.

[0012] On the other hand, the wrap packaging container 100 has a wrap storage section 2 at its bottom. Therefore, even if the thickness of the overlapping wrap portion is large, the overlapping wrap portion can be stored within the wrap storage section 2. In other words, it is easier to prevent the overlapping wrap portion from protruding from the bottom of the wrap packaging container 100 (container body 10). This allows the wrap packaging container 100 (container body 10) to be displayed stably as a product. Therefore, it becomes easy to display the wrap packaging container 100 (container body 10) in an orderly manner, maintain the display state, and prevent leakage of liquid. When customers see the wrap packaging container 100, they are less likely to feel uncomfortable, and it has the special effect of promoting their desire to purchase. Furthermore, because the container body 10 is rectangular, particularly rectangular, when viewed from above, it is easy to wrap the container body 10 with plastic wrap, and wrinkles are less likely to form in the wrap. In addition, when displaying the wrap-wrapping containers 100, it is easy to arrange them neatly and without gaps. Therefore, it can further stimulate the purchasing intent of customers.

[0013] (Details of the container for plastic wrap packaging) Next, we will describe the details of the wrap packaging container 100 (container body 10). As shown in Figures 1 and 3(a), the container body 10 has a plurality of placement surfaces 12 that protrude upward within the storage space 1. The plurality of placement surfaces 12 are inclined in the same direction. Specifically, the plurality of placement surfaces 12a to 12i are inclined to face towards the front (-Y direction). It is envisioned that different types of food contents will be placed on each of the plurality of placement surfaces 12. In the case of relatively high-end contents (food) where each item is placed in a separate location, customers tend to select products more carefully. Therefore, the aesthetics of the display are particularly important.

[0014] Each of the multiple placement surfaces 12 (12a to 12i) is provided with a recess 13 (13a to 13i). It is envisioned that foods that leak liquid, such as raw fish or raw meat, may be placed on the multiple placement surfaces 12a to 12i. In this case, the recesses 13a to 13i provided on the multiple placement surfaces 12 will function to receive the liquid, such as the drip. This will help maintain the freshness of the food placed on the surface. In addition, since the liquid is received within the multiple recesses 13a to 13i rather than remaining around the food, the appearance of the product is less likely to deteriorate.

[0015] Adjacent mounting surfaces 12 in the depth direction (Y-axis direction) are arranged such that the upper end of one mounting surface 12 is adjacent to the lower end of the other mounting surface 12. Adjacent mounting surfaces 12 in the depth direction refer to two mounting surfaces 12 having, for example, the relationship between mounting surface 12a and mounting surface 12d, or mounting surface 12d and mounting surface 12g. With this configuration, contents can be arranged attractively on multiple mounting surfaces 12a to 12i, and when viewing the wrap packaging container 100 as a product from the front, the contents contained in the storage space 1 can be clearly seen all the way to the back. Furthermore, since the size of the container body 10 in the height direction (Z-axis direction) can be kept from increasing, the stability when the wrap packaging containers 100 as products are stacked in the height direction for storage or display is improved.

[0016] Furthermore, adjacent mounting surfaces 12 in the width direction (X-axis direction) are arranged so that their lower ends are adjacent to each other. Adjacent mounting surfaces 12 in the width direction refer to two mounting surfaces 12 having, for example, the relationship between mounting surface 12a and mounting surface 12b, or mounting surface 12b and mounting surface 12c. With this configuration, the container body 10 is configured to spread out in the width direction, so when the wrap packaging container 100 displayed as a product is viewed from the front, the contents look good.

[0017] A bottom surface 14 is provided at the boundary between adjacent mounting surfaces 12 in the depth direction. More specifically, a bottom surface 14a is provided between the mounting surfaces 12a to 12c and the mounting surfaces 12d to 12f, and a bottom surface 14b is provided between the mounting surfaces 12d to 12f and the mounting surfaces 12g to 12i. As a result, a space is created between adjacent mounting surfaces 12 in the depth direction, making it easier to view the contents arranged on the back side. Therefore, the appearance of the wrapping container 100 as a product is further improved.

[0018] Also, each of the bottom surfaces 14 (bottom surfaces 14a and 14b) is composed of flat surfaces continuously provided along the lower ends of the adjacent mounting surfaces 12 in the width direction. And the bottom surface 14 forms a flat surface that is also continuous with at least one bottom surface of the recess 13. Specifically, the bottom surface 14a forms a flat surface that is continuous with the bottom surface of one recess 13b. Also, the bottom surface 14b forms a flat surface that is continuous with the bottom surfaces of three recesses 13d to 13f. Thereby, the shapes such as the concavities and convexities and corners formed in the container body 10 can be minimized, and the area of the planar portion can be increased. For this reason, it is easy to clean the container body 10 after use without leaving any residue. Therefore, the container body 10 after use can be hygienically stored at home or the like. Also, since it is easy to recycle, the environmental load can be reduced.

[0019] At both ends of the bottom surface 14, depressions 15 recessed downward are provided. At both ends in the width direction of the bottom surface 14a, depressions 15a and 15b are continuously provided, and at both ends in the width direction of the bottom surface 14b, depressions 15c and 15d are continuously provided. The bottom surface 14 adjacent to this depression 15 is continuous with the recess 13b and the recesses 13d to 13f as described above. That is, among the plurality of recesses 13, when the wrap packaging container 100 as a product is particularly displayed, the liquid accumulated in the recesses 13b, 13d to 13f on the back side that are particularly easily visible flows into the depression 15 through the bottom surface 14 and is easily accommodated. That is, the liquid can be further isolated from the contents (food) placed on the plurality of placement surfaces 12, and the freshness of the contents (food) can be maintained while further preventing a decrease in appearance. In particular, since the recesses 13b, 13d to 13f are continuous with the bottom surface 14, the liquid easily flows and is easily accommodated in the depression 15. Regarding the recesses 13a and 13c on the back side, they are formed deeper in order to have other functions to be described later. Therefore, since the liquid can be sufficiently accommodated in the same way as the depression 15, no problem occurs even if the liquid does not move to the depression 15.

[0020] The bottom surface 14 and the depressions 15 provided at both ends thereof function as a storage surface 24 and a storage bank 25 on the back side (downward, -Z direction side) thereof (see FIGS. 1, FIG. 2, etc.). More specifically, the bottom surfaces 14a and 14b respectively form storage surfaces 24a and 24b that are recessed upward on the back side. Further, the depressions 15a to 15d respectively form storage banks 25a to 25d that protrude downward on the back side. The storage surface 24a, the storage banks 25a and 25b form a wrap storage portion 2a, and the storage surface 24b, the storage banks 25c and 25d form a wrap storage portion 2b. In other words, the wrap storage portion 2 has at least a pair of storage banks 25 that protrude downward therefrom and a storage surface 24 that extends between the pair of storage banks 25.

[0021] Such a wrap storage section 2 is provided on the back side of the boundary between adjacent mounting surfaces 12 in the depth direction. As described above, these adjacent mounting surfaces 12 are arranged so that the end located on the upper side of one mounting surface and the end located on the lower side of the other mounting surface are adjacent to each other. By providing the wrap storage section 2 in this way, it is possible to prevent the space below the container body 10 from becoming too small on the back side of the lower end of the mounting surface 12. In other words, it is possible to reliably store the overlapping portion of the wrap formed by overlapping the wrap and prevent it from falling out.

[0022] As shown in Figure 3(b), each of the wrap storage sections 2 is located in the center of the container body 10 when viewed from below (or above). When wrapping the container body 10 with plastic wrap, the wrap is usually gathered in the center of the lower part of the container, forming a wrap overlap. In other words, by providing the wrap storage sections 2 in this position, the wrap overlap can be efficiently stored in the wrap storage sections 2 when wrapping with plastic wrap.

[0023] Furthermore, each of the wrap storage sections 2 is provided along the longitudinal direction of the container body 10. In small shops and the like, a tool called a hand wrapper is often used, which holds a roll of wrap and wraps the container by moving the wrapper itself around the container. When using this hand wrapper in particular, the wrap that is placed over the container body 10 from above is usually folded downwards at both ends along the longitudinal direction of the container body 10, and then folded downwards at both ends along the short direction. Even in such cases, if the wrap storage sections 2 are provided along the longitudinal direction, the amount of wrap that is folded and overlapped along the longitudinal direction can be distributed when folding the wrap in the short direction. In other words, it is possible to prevent the wrap from concentrating and overlapping at specific points along the longitudinal direction of the wrap storage section 2, and to appropriately suppress the amount of wrap that sticks out downwards. The advantages of wrap packaging will be described in detail later.

[0024] As shown in Figure 4, the length from the receiving surface 24 to the tip (lower end, -Z end) of the receiving rim 25 is defined as the depth D of the wrap receiving section 2. Since the receiving surface 24 does not need to be flat, the depth D is not necessarily constant. However, the minimum depth D is preferably about 1 mm or more, and more preferably about 2 mm or more. The minimum depth D may be about 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, or 3 mm or more. Since the thickness of the wrap typically used for container packaging is about 10-20 μm, if the depth D is about this size at the point where it is minimum, the overlapping part of the wrap can be sufficiently accommodated in the wrap receiving section 2.

[0025] On the other hand, the maximum depth D is preferably about 10 mm or less, and may be about 9, 8, 7, 6, 5, 4, or 3 mm or less. By keeping the depth D to this extent at the point where it is at its maximum, the wrap storage section 2 does not become too deep, so that sufficient heat from the heater can reach the overlapping wrap (wrap overlap section). In other words, the wraps can be sufficiently tightly bonded (fused) together. In addition, since the height of the container body 10 is kept low, the stability when displaying the wrap packaging container 100 as a product can be improved, making it easier to maintain an aesthetically pleasing display.

[0026] Furthermore, among the multiple mounting surfaces 12 shown in Figure 1, the mounting surfaces 12g to 12i located in the front row (closest to the viewer, -Y direction) and the mounting surfaces 12d to 12f located in the middle row have upper surfaces that are recessed upwards on their back sides, as shown in Figure 2. These spaces 2s can also function as spaces for accommodating plastic wrap. In other words, the spaces 2s are on the back side of the boundary between adjacent mounting surfaces 12 in the depth direction, and can be said to form part of the plastic wrap storage section 2 formed in the central part of the container body 10 when viewed from above (or below).

[0027] As shown in Figures 2 and 3(b), the storage rims 25a to 25d have a shape in which the area viewed from above decreases as they move downwards. This shape of the storage rim 25 further improves the stability when displaying the wrap packaging container 100 as a product. Furthermore, because the container body 10 is easy to grasp by hand, it is easy to guide the wrap along the storage rim 25 and lead its end into the wrap storage section 2 when wrapping. In addition, because it is easy for customers to grasp when they pick up the wrap packaging container 100 as a product, it is possible to prevent the contents from being dropped or tilted and the contents from being disturbed.

[0028] Of the multiple recesses 13 provided in the storage space 1 shown in Figure 1, etc., recesses 13a and 13c located at both ends in the width direction of the last row (the innermost, +Y direction side) function as legs 23 (legs 23a and 23c) on their back side (downward), as shown in Figure 2, etc. Therefore, as described above, recesses 13a and 13c are formed deeper than the other recesses 13b, 13d to 13i.

[0029] Furthermore, among the multiple mounting surfaces 12 shown in Figure 1, etc., the mounting surfaces 12g to 12i located in the front row function as legs 26 extending along the width direction on their reverse side, as shown in Figure 2, etc. In this way, when the container is placed with the storage space 1 facing upwards, the support section is formed to support the container body 10 at seven points: the legs 23a and 23c, the legs 26, and the storage rims 25a to 25d. This further improves the stability when displaying the wrap packaging container 100 as a product. Note that this support section only needs to be provided below the container body 10 and support the container body 10, and at least three sections are sufficient. In this embodiment, it is particularly preferable that support sections (legs 23a, legs 23c, and legs 26) are provided at the four ends of the container body 10 when viewed from above (or below).

[0030] The wrap packaging container 100 described above can be used particularly favorably as a container for fresh foods. Examples of fresh foods include fresh fish, fresh meat, and fruits and vegetables. Fresh foods are often wrapped in plastic wrap at the point of sale. If inexperienced employees rush the wrapping process within limited working hours, the wrap may overlap unevenly, forming large overlapping areas. Furthermore, when fresh foods are the contents of the container body 10, it is undesirable to heat the contents, so heating with a heater may not be performed during the wrapping process. Even when heating with a heater is performed, it may be possible to set the heater to a lower temperature than usual. In such cases, fearing that the wrap will not adhere (fuse) properly, it is possible to increase the amount of wrap overlapped to form large overlapping areas. Thus, even when fresh foods are the contents and large overlapping areas are expected to form, the wrap packaging container 100 allows the overlapping areas to be accommodated in the wrap storage section 2 of the container body 10. Therefore, the overlapping portion of the wrap is less likely to protrude from the lower side of the container body 10, and is less likely to interfere with the display of the wrap packaging container 100.

[0031] Furthermore, the wrap packaging container 100 has a wrap storage section 2 that ensures a distance between the heater and the food placed on the container body 10. In other words, it also has the effect of making it difficult for the heat from the heater to be transferred to the food. Therefore, if fresh food is stored in the wrap packaging container 100, the freshness of the fresh food can be better preserved. In addition, by using the wrap packaging container 100, the appearance of the food placed in the container body 10 is improved both by the fact that the wrap storage section 2 can accommodate the overlapping wrap portion and by the fact that the contents can be piled up and placed on multiple placement surfaces 12. In particular, when the contents are relatively high-end foods such as sashimi or meat for yakiniku, which are placed on multiple placement surfaces 12 according to type, cut, etc., the wrap packaging container 100 can also contribute to creating a sense of exclusivity.

[0032] [Method for manufacturing food packaging] Next, with reference to Figure 5, a method for manufacturing food packaging will be described. Figure 5 shows diagrams illustrating a method for manufacturing food packaging (Figures 5(a) to 5(e)). Although Figure 5 shows an example of manufacturing food packaging manually, the method of manufacturing food packaging is not limited to this. For example, food packaging may be manufactured semi-automatically using a tool such as a hand wrapper, or fully automatically using a machine such as a packaging machine.

[0033] [1] As shown in Figure 5(a), first, food is placed in the storage space 1 of the wrap packaging container 100 through the opening 1a. Here, it is preferable to place the food on the multiple placement surfaces 12a to 12i in an aesthetically pleasing manner. Furthermore, when placing food that may leak liquid such as drip, such as fresh fish or meat, as the contents, it is preferable to arrange the contents so that at least a portion of them covers at least a portion of the multiple recesses 13a to 13i. This allows the liquid to flow into and be received in the multiple recesses 13a to 13i, thereby maintaining the freshness of the food. The liquid received in the multiple recesses 13a to 13i may further flow into and be received in the depression 15 via the bottom surface 14.

[0034] [2] Next, as shown in Figure 5(b), the plastic wrap is placed over the plastic wrap packaging container 100 (container body 10) from above. At this time, the plastic wrap should be larger than the opening 1a. Then, as shown in Figures 5(c) to (d), the placed plastic wrap is folded downwards and overlapped to form a plastic wrap overlap section, and the container is then packaged by placing it in the plastic wrap storage section 2. More specifically, first, as shown in Figure 5(c), the plastic wrap is pulled in the longitudinal direction and folded downwards along the edges located at both ends in the longitudinal direction. Then, as shown in Figure 5(d), the plastic wrap is pulled in the short direction and folded downwards along the edges located at both ends in the short direction. This makes it easier to prevent wrinkles by sufficiently tensing the plastic wrap covering the opening 1a, thus making it easier to see the food placed in the storage space 1. It can also be expected to give customers the impression that the product is carefully packaged, making it easier for them to pick it up. In other words, the appearance of the plastic wrap packaging container 100 as a product is further improved.

[0035] As described above, since the wrap storage section 2 is provided along the longitudinal direction (X-axis) of the container body 10, when folding the wrap downward along the edges located at both ends in the short direction, it is not necessary to concentrate the wrap at a specific point in the longitudinal direction below the container body 10. In other words, there is no need to forcibly gather and overlap the wrap in one place, and it is difficult to form an excessively large overlapping section of wrap. Therefore, the folded wrap can be contained within the wrap storage section 2 as needed and sufficiently, preventing the overlapping section of wrap from sticking out below the container body 10. Furthermore, because the receiving ridges 25a to 25d have a shape that tapers downwards, it is easier to grasp the container body 10 by hand when folding the wrap to form the overlapping wrap portion, and it is easier to guide the wrap into the wrap receiving portion 2 and position the overlapping wrap portion within the wrap receiving portion 2.

[0036] In this way, a food package as shown in Figure 5(e) can be manufactured. As described above, because the container body 10 is roughly rectangular in shape, when folding the wrap downwards, the wrap can be concentrated at the four corners and then gathered in the wrap storage section 2 provided in the lower center of the container body 10 to form a wrap overlap section. In other words, the wrap covering the opening 1a can be sufficiently taut, making it easier to prevent wrinkles from forming. By using the methods described above, it is possible to easily provide visually appealing food packaging.

[0037] [Differentiation] The following describes variations of the wrap packaging container 100 described above. The embodiments described above and the following descriptions are interchangeable.

[0038] In the above-described embodiment, the shape of the container body 10 when viewed from above was rectangular, but it is not limited to this. For example, such a shape may be elliptical, circular, triangular, pentagonal, hexagonal, etc. However, it is preferable that the shape of the container body 10 when viewed from above is polygonal. In this case, it is easier to gather and overlap the wrap folded downwards along each side in the wrap storage section 2.

[0039] Furthermore, it is preferable that the shape of the container body 10, when viewed from above, be an even-numbered polygon. This makes it easier to apply the plastic wrap to the container body 10 without wrinkles between opposing sides, thereby improving the appearance of the plastic wrap container 100 as a product.

[0040] In the embodiment described above, a case was described in which nine mounting surfaces 12 are provided in three columns in the depth direction and three rows in the width direction, but the number and arrangement of the mounting surfaces 12 are not limited to this. The number of mounting surfaces 12 may be, for example, two to eight or ten or more. Also, the number of mounting surfaces 12 may be two or fewer columns or four or more columns, or two or fewer rows or four or more rows. For example, if the number of mounting surfaces 12 is four, the container body 10 may be provided only with mounting surfaces 12a, 12c, 12g, and 12i. Also, if the number of mounting surfaces 12 is five, the container body 10 may be provided with mounting surfaces 12a to 12c, 12g, and 12i, and the widths of the mounting surfaces 12 may be made different so that the width (length in the X-axis direction) of mounting surfaces 12a to 12c and the width (length in the X-axis direction) of mounting surfaces 12g and 12i are approximately equal.

[0041] However, it is preferable that the multiple mounting surfaces 12 be arranged in two or more rows in the depth direction, that is, multiple surfaces in the depth direction. In this case, as described above, the lower end and upper end of adjacent mounting surfaces in the depth direction are adjacent to each other. Of these, the lower end has a wrap storage section 2 on its back side, which solves the problem of not being able to store wrap due to the small space below the container body 10. In other words, when multiple mounting surfaces 12 are provided in the depth direction, the effects of the wrap packaging container 100 according to this disclosure can be more significantly realized.

[0042] In the embodiments described above, a method of directly covering the container body 10 with plastic wrap was explained, but the invention is not limited to this. The wrap packaging container 100 may be equipped with a lid that covers the opening 1a of the container body 10. In this case, the wrap packaging can be done by covering the container with plastic wrap from above the lid. That is, the wrap packaging container 100 is wrapped by covering it with plastic wrap from above. However, it is more preferable not to have a lid, in which case the effort of further covering the container body 10 with a lid when placing and wrapping food in stores can be reduced. In addition, since less material is consumed when manufacturing the wrap packaging container 100 because the lid is omitted, the environmental burden of manufacturing the wrap packaging container 100 can be reduced.

[0043] In the embodiments described above, the container body 10 (wrap packaging container 100) is formed by deforming a sheet material or the like in the thickness direction, and its thickness is substantially constant. However, the invention is not limited to this. For example, the container body 10 (wrap packaging container 100) may be manufactured by injection molding of a resin material, and its thickness does not have to be substantially constant. For example, the shape of the storage space 1 of the container body 10 may be as shown in Figure 1, and below the container body 10, the storage rim 25 may surround the entire circumference of the container body 10. That is, the thickness of the container body 10 may be larger at the upper end of each of the multiple mounting surfaces 12, and smaller at the lower end. However, the embodiment described above is more preferred, as in this case, the amount of resin material consumed is reduced, thus reducing the environmental burden of manufacturing the wrap packaging container 100.

[0044] In the embodiment described above, the case in which the width direction of the container body 10 coincides with the longitudinal direction and the depth direction coincides with the short direction was explained, but of course, it is not limited to this. However, in the case of this embodiment, the appearance when displaying products is improved.

[0045] In the embodiments described above, the manufacturing of the food packaging involved simply covering it with plastic wrap and housing the overlapping portion of the wrap in the wrap housing portion 2, but the invention is not limited to this. For example, the manufacturing method of the food packaging may further include a step of reducing the pressure in the housing space 1 covered with plastic wrap. In this case, the freshness of the food can be maintained for a longer period of time.

[0046] Although each embodiment of this disclosure has been described above, the embodiments described in each embodiment can be combined with each other. Furthermore, the product may be provided in the following embodiments.

[0047] (1) A wrap packaging container comprising a container body, wherein the container body has a storage space for storing contents through an opening that is open at the top, and a wrap storage section for storing a wrap overlap portion formed by overlapping wrap that is placed over the container body from above and then folded downwards.
