Description

The present invention relates to a carton with a cushioning function for individually packaging fragile items such as eggs.

Fragile eggs are often sold commercially in containers such as molded plastic trays. In recent years, the idea of carbon neutrality has become widespread due to rising environmental awareness and resource conservation, and there is a movement to replace plastic trays with containers made from paper and other renewable resources. Individually wrapped cartons, in which eggs or similar products surrounded by a curved surface are stored individually in a paper container, have a special structure to comfortably store the products and support the curved surface. Needed. Examples of articles having such a shape include, in addition to eggs, light bulbs, tennis balls, and the like. Additionally, when storing fragile items such as eggs, a cushioning function is required to prevent external shocks.

Various paper cartons corresponding to this have also been proposed (for example, Patent Documents 1 and 2). However, conventionally, such cartons tend to have complicated structures, require a large number of panels for box manufacturing, are inconvenient to take blanks, and the process of manufacturing boxes is complicated, leading to increased costs. Cases cannot be made by folding blank sheets, and multiple sheets must be pasted together, and manual work is required for pasting, making automatic box manufacturing difficult, resulting in increased costs, or There were problems such as the large space around the eggs in the carton, which could cause the eggs to move around a lot during transportation, etc., and improvements were desired.

FIG. 1 is a perspective perspective view of an embodiment of an individual wrapping carton (hereinafter also simply referred to as a "carton") of the present invention. Further, FIG. 2 is a developed view of a blank sheet of an embodiment of the individually wrapped carton of the present invention. In the following description of the embodiment, eggs will be used as an example of the article to be stored. The carton 1 is formed by folding and gluing the blank sheet 1b shown in FIG. 2, and FIG. 1 transparently shows the shape of the formed carton 1 when viewed from an oblique direction. Note that some glue allowances are omitted for ease of viewing. The material of the blank sheet 1b is not particularly limited as long as it has sufficient strength, rigidity, and processing suitability to hold the article, but it is preferable to use a paper material, and typically paperboard or corrugated cardboard is used. .

As shown in FIG. 1, the individual wrapping carton 1 of this embodiment has a front plate 11, a back plate 12, a left side plate 14, and a right side plate 15 that stand up from the periphery of a rectangular bottom plate 10 and are attached to each other to form a box shape. The open top side of the carton 1 can be covered with a top lid 13 connected to the back plate 12, and the carton 1 can be closed by inserting an insertion piece 113. A window 111 through which the inside of the carton 1 can be seen is provided on the front plate 11. Although a window is not essential, it is preferable to provide one because it allows the state of the eggs 30 stored inside to be confirmed. A window 112 is similarly provided on the back plate 12.

Inside the carton 1, a right adhesive plate 16 connected to the right side plate 15 is folded inward, and a right support plate 17 and a lower right support plate 18 are formed in the shape of shelves. A lower left support plate 20 and a left support plate 21 are formed in the shape of a shelf, and are further provided with a left adhesive plate 22 and an adhesive margin 23. The right adhesive plate 16 and the left adhesive plate 22 are adhered to the inner surfaces of the right side plate 15 and the left side plate 14, respectively, and the bottom adhesive plate 19 is adhered to the bottom plate 10. The glue margin 23 is adhered to the outer surface side of the left side plate 14.

Here, cutouts 171 and 181 are provided in the right support plate 17 and the lower right support plate 18 to form portions for holding eggs 30, which are articles to be stored. The notch 181 has a shape that follows the outer shape of the lower part of the egg, and the notch 171 is oriented such that the long axis direction of the egg is in the vertical direction, so that the egg 30 can be stored in the notch 181. It is preferable that they are formed in a size similar to the above, and that both of them have a curved shape. Notches of the same shape are also provided on the left support plate 21 and the lower left support plate 20. In order for the notch 181 to support the lower end side of the egg, the length w of the bottom adhesive plate 19 in the left-right direction in the figure is set shorter than the length in the short axis direction of an average egg.

FIG. 2 is a developed view of a blank sheet forming the carton 1. The blank sheet 1b has a front plate 11, a back plate 12, a left side plate 14, and a right side plate 15 arranged around the bottom plate 10, and further includes a right adhesive plate 16, a right support plate 17, and a lower right support plate 18 from the right side plate 15. , the bottom adhesive board 19, the lower left support plate 20, the left support plate 21, the left adhesive board 22, and the boards up to the glue allowance 23 (hereinafter, these boards are collectively or individually referred to as "panels") are aligned in one straight line. They are arranged side by side (in the left and right direction in the figure). Further, a front plate 11 is connected from the bottom plate 10 in a direction perpendicular to the first straight line (in the vertical direction in the figure), a back plate 12 is connected to the opposite side of the front plate 11, and a top cover 13 and an insertion piece 113 are connected to the back plate. It is set up. It goes without saying that the panel from the right adhesive plate 16 to the adhesive margin 23 may be laterally reversed and connected to the left side plate 14.

The border line of each panel is a folding line, and each folding line is folded, and the left side plate 14 and right side plate 15 are attached to the front plate 11 and the back plate using adhesive plates 114 and 115 provided on both sides in the vertical direction in the figure. By bonding it with the face plate 12, the carton 1 can have a form as shown in FIG. In FIG. 2, the carton 1 is folded so that the illustrated surface becomes the inner surface of the carton 1, and the broken lines indicate the valley fold lines and the dashed-dotted lines indicate the mountain fold lines.

A cutout 180 is formed by providing cutouts 171 and 181 in a portion extending from the right support plate 17 to the lower right support plate 18, and a similar cutout is formed in a portion extending between the left support plate 21 and the lower left support plate 20. has been done.

Hereinafter, how to assemble the individual wrapping carton 1 will be explained. FIG. 3 is a diagram showing the blank sheet of FIG. 2 folded back along folding lines 116. The right adhesive plate 16 formed on the folded part overlaps the right side plate 15, and the bottom adhesive plate 19 overlaps approximately the center of the bottom plate 10 with the right support plate 17 and lower right support plate 18 in between, and the lower left side plate 16 overlaps with the right side plate 15. The left adhesive plate 22 overlaps the side edge of the left side plate 14 via the support plate 20 and the left support plate 21, so that the adhesive margin 23 protrudes outward. In other words, the size of each panel is set so that it will look like the above when folded back.

Then, they are bonded together at three locations: the right adhesive plate 16 and the right side plate 15, the bottom adhesive plate 19 and the bottom plate 10 at approximately the center, and the left adhesive plate 22 and the left side plate 14 at the side edges. For pasting, a known adhesive material such as adhesive or double-sided adhesive tape is appropriately selected and added to the right adhesive plate 16, bottom adhesive plate 19, and left adhesive plate 22 in advance, and the pieces are crimped when folded back. Just glue it. Further, adhesive material is similarly applied to the adhesive portion 23, which is then folded into the back side of the left side plate 14 and adhered.

FIG. 4 is an explanatory diagram of the process of folding up the blank sheet 1b in the above-described manner to form the carton 1, and shows a cross section of the blank sheet 1b at a line segment AB in the direction of the white arrow in FIG. This is the view from. When the left side plate 14 and the right side plate 15 are folded up along the fold lines 104 and 105 from the folded and flat state shown in FIG. 4A shown in FIG. 122 and the mountain-fold ruled lines 118 and 121 are naturally folded to form a crease, and the lower right support plate 18 and the lower left support plate 20, which are not bonded together, stand up (FIG. 4(b)).

Furthermore, if the left side plate 14 and the right side plate 15 are raised vertically, the lower right support plate 18 and the lower left support plate 20 will also stand up vertically, and the right support plate 17 and the left support plate 21 will become horizontal shelf plates. (Figure 4(c)). The eggs 30 can be set and stored in the notches provided in the right support plate 17, the lower right support plate 18, the left support plate 21, and the lower left support plate 20. By appropriately setting the size of each panel in consideration of the average size of the egg 30, sufficient space can be secured around the egg 30 to provide a buffering function against external shocks. Can be done. The space around the eggs 30 may be appropriately set depending on the material and strength of the blank sheet 1b constituting the carton 1.

The front plate 11 and the back plate 12 are similarly raised from the folding lines and bonded to the left side plate 14 and right side plate 15 using glue margin plates 114 and 115, respectively, to form a box shape as shown in FIG. 1. . It is optional whether the front plate 11 or the rear plate 12, or the left side plate 14 or the right side plate 15, is raised first. As described above, the wrap-round caser device can be formed into a box-like shape with an egg storage section by simply folding it back along the folding line 116, folding it up in the same direction along the folding lines 104 and 105, and pasting it together. It is easy to apply to box making using automatic box making equipment such as

The adhesive plates 114 and 115 can be pasted on the outside or inside of each panel, and the thickness of the blank sheet etc. will depend on which side they are pasted on. The size of each panel may be slightly adjusted taking this into consideration.

FIG. 5 is an exploded view of a blank sheet forming another embodiment of an individually wrapped carton. In the blank sheet 2b of this embodiment, a tab 172 for holding down the egg 30 is provided in a notch 171 provided for storing the egg. The tab 172 is bent when storing the egg 30, and is pressed against the egg 30 by the repulsive force due to its natural elasticity, thereby regulating the movement of the egg 30, and preventing the egg from moving in the notch during transportation. You can prevent this from happening. The tab 172 can be bent in any direction; if it is bent downward as shown in FIG. 6(a), it will be easier to store the egg 30, and if it is bent upward as shown in FIG. 6(b), the egg 30 will be held downward. Therefore, vertical movement of the egg 30 can be more effectively suppressed, and both effects can be obtained by folding the egg 30 in the vertical direction as shown in FIG. 6(c). The other parts are the same as the blank sheet 1b, so the explanation will be omitted.

In addition, in the carton 1, the height of the carton 1, the size of the bottom plate 10 and the top lid 13, and the cut size are such that the long axis direction of the eggs 30 is the vertical direction of the carton 1, and the more pointed side is held as the top lid 13 side. It is preferable to set the sizes of the notches 171 and 181. In general egg filling equipment, from the standpoint of storage efficiency, the eggs are arranged in the above-mentioned orientation and set in the feeding device, from where they are taken out by an automatic device such as a vacuum device and placed in the book. This is because when feeding eggs into the carton 1 of the invention, it is possible to take out the eggs in the originally set orientation and feed the eggs to the holding part of the carton 1, which improves process efficiency. That is, the carton of the present invention can be suitably applied to a general automatic egg filling device.
