[Industrial applications]

 The present invention relates to a carton for a frozen food vending machine using a stacking method. In more detail, a carton is provided with a protrusion on the bottom of the carton, and water droplets are frozen due to dew condensation during the distribution process so that defective discharge and breakage from vending machines do not occur.

[Prior Art]

 In recent years, the utilization rate of frozen foods that can be stored for a long period of time at home has increased. For example, frozen food in a plastic case or a plastic bag is stored in a beautifully decorated carton, frozen shrimp, dumplings, spices, etc. that can be thawed and cooked, or can be eaten immediately by heating in a microwave oven. There are many cooked products on the market. Some of these are lined up in freezer cases at stores, but recently vending machines that are easy and free to purchase have become available. The method of stocking the vending machine for frozen foods is often a spiral method (for example, the outline is shown in FIG. 3). This type of vending machine has a small contact area between makeup cartons and pushes the weight of the product to the side of the carton a little to push it out, so there are few product discharge defects due to freezing, but loading efficiency (stock of vending machine stock The quantity was so bad that it was necessary to replenish it.

Therefore, a stacking system (see FIG. 4a) may be adopted in which a large number of products, which are often used in vending machines such as cigarettes, are stacked on top of each other and the lower boxes are dropped one by one. For example, in the case of frozen food cartons, there remains a problem that the contact area becomes large and the stacked cartons freeze each other, resulting in defective discharge of products from the vending machine.

[0004]

[Problems to be solved by the device]

 The frozen foods are placed in a carton and stored in a freezer at about -20 ℃ to -40 ℃. During the distribution process, the frozen foods are temporarily transferred to a refrigerated vehicle and delivered to each vending machine or a frozen case at a store. At the same time, fine freezing condensation (a phenomenon in which water vapor in the atmosphere condenses into water droplets at low temperatures) occurs in the carton due to changes in the freezing temperature during the distribution process. Then, when it is refrozen again (about -10 ° C to -20 ° C) in a vending machine or a freezing case, fine mist-like dew condensation or water droplets formed by dew condensation are frozen as they are. For this reason, the conventional rectangular carton has a large contact area between the cartons (see Fig. 4), and when stacked vertically, fine fog-like dew condensation on the top and bottom of the carton and condensation can form. Water droplets do not flow anywhere and freeze, making it difficult for the product to peel off, which is a cause of defective discharge in stacking type vending machines. Also in the case of a freezing case, when the frozen state becomes strong, the cartons may cause delamination and break the cartons when taken out. Therefore, the present invention is designed so that even if the cartons are stacked, the contact area is made as small as possible, and the water droplets of dew condensation that causes freezing run down, so that the water droplets do not flow into the contacting part, and automatic sales are performed. It is an object of the present invention to provide a carton for frozen foods that does not cause defective discharge in a machine or tear due to delamination of a frozen case.

[0005]

[Means for Solving the Problems]

 In order to solve the problem, the present invention provides a fold line (20, 20, 20, 20) curved inward toward the top and bottom of at least the top plate (10) and the bottom plate (11), and through the fold line. The arc-shaped wall plates (16,16,17,17) are connected in series, and the flaps (18,18,18,18,18,18) are attached to the sides of the top plate and the bottom plate through vertical folding lines (22,22,22,22). Side plate (13, 13) provided with (19, 19) and glue strip (14) are connected in series, and each top line and bottom plate are formed in an arched shape with a bulge. In a carton for frozen foods, two protrusions (12, 12) are formed on the front side of the bottom plate to prevent water droplets from freezing, resulting in defective discharge of the vending machine and tearing due to delamination in the freezing case. is there.

To explain in more detail, the carton of the present invention is an arched carton with a bulge on the top plate (10) and the bottom plate (11), and two protrusions are perpendicular to the bottom plate. (12,12) is provided. This ridge is formed, for example, from the back side of the bottom plate in the same manner as embossing with ruled lines, and two ridges (12, 12) of about 2 mm to 4 mm are provided on the front side by pushing a little deeper. By stacking these (see Fig. 2), even if the lower carton top plate (10) is dented by the weight of the contents, it is supported by the upper carton protrusion, and the contact area of the carton is only inside the protrusion. It can be suppressed by the area.

The flow of water droplets (30, 30) formed by the condensation of the carton during the distribution process falls along the side plates (13, 13) and the glue strip (14) and rises (12, 30). It stops at 12) and falls on the lower carton. These water drops do not flow over the protrusions and flow into the contact surface (30) .For example, the contact surface freezes less during re-freezing with an automatic vending machine, so it is easy to peel off and a stacking type vending machine is also used. become able to.

[0008]

[Action]

 The frozen food carton of the present invention has two protrusions (12, 12) formed on the bottom plate (11) at equal intervals to collect fine mist-like dew condensation caused by temperature change during distribution. The flow of accumulated water drops is stopped, and it gradually falls into the lower stacked carton. In addition, the carton has an arched shape with a bulge on the top plate (10) and bottom plate (11), so water droplets formed by dew condensation can easily flow through the side plate. Is becoming In addition, the flowing water drops stop at the ridges (12, 12) and do not enter the contact surfaces inside the two ridges (near the central part of the upper bottom plate and the lower top plate that are stacked). Since the frozen area can be reduced even when placed in a machine or freezer case and re-frozen, there is no worry of blocking due to freezing even when stacked.

【Example】

An embodiment of the present invention will be described with reference to the drawings. FIG. 1A is a development view of a frozen food carton according to an embodiment of the present invention. The base material is a paper having a weight of about 250 kg / m ^{2 to} 450 kg / m ² such as a paperboard and a white ball, and a makeup applied by suitable printing. As shown in Fig. 1 (a), fold lines (20,20,20,20) curved inward are provided on the top and bottom of the top plate (10) and bottom plate (11) to form an arc shape through these fold lines. The wall plates (16,16,17,17) of are connected in series. Further, side plates (13, 13) provided with flaps (18, 18, 19, 19) through vertical folding lines (22, 22, 22, 22) on the sides of the top plate and the bottom plate. Substitute piece (14) in series. Next, two ruled lines are embossed from the back side of the bottom plate (11) to form two protrusions (12, 12) with a height of about 2 mm to 4 mm on the front side of the carton. Blank plate. Fold it according to the fold lines and perforation lines shown on the blank board, and assemble it by pushing the wall boards (16,16,17,17) inward, and have bulges on the top and bottom boards, and two at the bottom. This results in an arched carton with raised ridges (see Figure 1b).

The carton is folded from the curved fold line (20,20,20,20) and the arc-shaped wall plates (16,16,17,17) are pushed inward to bulge the top and bottom plates of the carton. However, when they are stacked, the two protrusions (12, 12) also serve to prevent the contact area from being crushed by the weight of the contents and crushing over the entire surface.

FIG. 2 is an explanatory view showing the flow of water droplets when the assembled cartons according to the embodiment are stacked. For example, fine mist-like dew condensation collects during transportation by a cold carrier to form water droplets, and the side plates (13, 13) and glue strips (14) are connected to the top plate (10) and the bottom plate (11). Go around. However, the water drops stop at the two ridges (12, 12) and then run down to the top plate edge of the lower carton. In this case, water droplets do not enter the inside of the protrusion (broken arrows 50, 50 in FIG. 2 indicate the flow of water droplets).

The area of the contact surface (30) between the top plate (10) and the bottom plate (11) of the stacked cartons is small, and both the arch-shaped top plate and bottom plate are deformed depending on the weight of the stacked contents. The area that is previously supported by the two ridges (12,12) and is in contact is at most the inside of the two ridges. In addition, since water drops do not flow inside the protrusions, the degree of blocking due to freezing is weak even if it is re-frozen by the vending machine, and it easily peels off by its own weight.

[0013]

[Effect of the device]

 In particular, the present invention is a stacking type frozen food vending machine, in which two protrusions are formed on the bottom plate of the carton shape without special treatment such as a release agent or an antifreezing agent on the surface of the carton. By using arched cartons with bulges on the top plate and bottom plate, water droplets formed by condensation are naturally flown using the inclination of the carton, and even if frozen, the contact area of the carton comrades Is small, so even stacking type vending machines can easily be peeled off and discharged due to their own weight. Further, the carton for frozen foods of the present invention can be used not only for vending machines but also for freezer cases at stores, and is a carton that is easy to take out without causing defects such as breaking of the carton due to blocking due to freezing.
