Description

Technical Field

[0001] The present invention relates to a shredding device for food trays that are foaming or non-foaming.

Background Art

[0002] In recent years, as various food containers, trays made of plastic or styrofoam have been used. Waste food trays after use are collected and processed by local governments. Although plastic and styrofoam food trays (waste) are lightweight, they have a large volume (bulky). Therefore, at home, it is desired to cut the food trays finely before taking them out as garbage to reduce the volume.

[0003] Therefore, for example, the shredder of Patent Document 1 is installed above the inlet of the shredder main body, and includes a first pressing means for horizontally pressing the input waste plastic, and a second pressing means for pressing the input waste plastic downward toward a rotary cutter built in the shredder main body. Therefore, in the case of the shredder of Patent Document 1, in order to press lightweight and bulky plastics in two directions, horizontal and upward, the plastics are surely flattened and the biting into the rotary cutter is promoted.

Modes for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the components described in the following examples are illustrative, and are not intended to limit the technical scope of the present invention thereto.

Example

[0011] (Configuration) First, the overall configuration of the food tray cutting device D of the present invention will be described with reference to FIG. 1. As shown in FIGS. 1 to 3, the food tray cutting device D of the present invention is formed in a plate shape that is deformed as a whole by a synthetic resin or the like, and has a plurality of first grooves 11 having a first depth h1, ···, and a first surface 10 provided with the first grooves 11, ···, and a second surface 20 provided with a plurality of second grooves 21 having a second depth h2 shallower than the first depth h1, ···, and the front and back are integrally provided. That is, the back surface (rear surface) of the first surface 10 is the second surface 20. In addition, a latching hole 31 is formed near the edge of the food tray cutting device D.

[0012] That is, as shown in the plan view of FIG. 2(a), the first surface 10 has three parallel first grooves 11, 11, 11 that are first recesses, and two parallel first protrusions 12, 12 therebetween. The depth h1 of the first groove 11 is deeper than the depth h2 of the second groove 21 on the back surface described later. As will be described later, this first surface 10 is mainly used to cut materials that are not foaming (for example, OPS, PET, PP, etc.).

[0013] More specifically, the first groove 11 has a trapezoidal cross section having an inclined surface 11a and a bottom surface 11b, and the inclined surface 11a guides the blade of the rotary cutter C to the bottom surface 11b. And as described above, the depth h1 of the first groove 11 - that is, the distance from the surface of the first protrusion 12 to the bottom surface 11b - is made deeper (longer) than the depth h2 of the second groove 21.

[0014] Similarly, as shown in the rear view of FIG. 2(b), the second surface 20 has two parallel second grooves 21, 21 which are second recesses, and three parallel second protrusions 22, 22, 22 therebetween. The depth h2 of the second groove 21 is shallower than the depth h1 of the first groove 11 of the surface described above. This second surface 20 is mainly used for cutting a foaming material (for example, PSP, PPF, etc.) as will be described later.

[0015] More specifically, the second groove 21 has a trapezoidal cross-section having an inclined surface 21a and a bottom surface 21b, and the inclined surface 21a guides the blade of the rotary cutter C to the bottom surface 21b. And as described above, the depth h2 of the second groove 21 - that is, the distance from the surface of the second protrusion 22 to the bottom surface 21b - is shallower (shorter) than the depth h1 of the first groove 11.

[0016] And in the cutting device D for the food tray of the present embodiment, the back side of the first groove 11 which is the first recess is the second protrusion 22. That is, as shown in the cross-sectional view of FIG. 3, the first groove 11 becomes the second protrusion 22 when viewed from the opposite side. Similarly, in the cutting device D for the food tray of the present embodiment, the back side of the second groove 21 which is the second recess is the first protrusion 12. That is, as shown in the cross-sectional view of FIG. 3, the second groove 21 becomes the first protrusion 12 when viewed from the opposite side.

[0017] Furthermore, as shown in FIGS. 1 to 3, the cutting device D for the food tray of the present embodiment has stopper walls 13, 23 formed on at least the extension lines of the starting points and ending points of the first groove 11 and the second groove 21 to prevent the rotary cutter C from escaping and to prevent damage to a desk or the like.

[0018] More specifically, on the first surface 10, a stopper wall 13 is formed so as to surround the periphery. The height of the stopper wall 13 is made higher than the height of the first convex portion 12 of the first surface 10, preventing the risk of runaway of the rotary cutter C. Similarly, on the second surface 20, a stopper wall 23 is formed so as to surround the periphery. The height of the stopper wall 23 is made higher than the height of the second convex portion 22 of the second surface 20, preventing the risk of runaway of the rotary cutter C. Further, the stopper walls 13 and 23 also have a function of preventing the table (such as a table or a desk) on which the shredding device D is placed from being damaged even if through holes are formed in the bottom surfaces 11b and 21b due to long-term use.

[0019] (Operation) Next, with reference to FIGS. 4(a) and 4(b), the operation of the shredding device D of the food tray of the present embodiment will be described.

[0020] First, the first surface 10 is mainly used for shredding materials that are not foaming materials (for example, OPS, PET, PP, etc.). As shown in FIG. 4(a), when shredding a non-foaming material tray T, although the thickness of the tray T is relatively thin but hard, the presence of the deep groove 11 (the first groove) makes it easy to have the feeling of cutting by the rotary cutter C, thus making it easier to shred the tray T.

[0021] On the other hand, the second surface 20 is mainly used for shredding foaming materials (for example, PSP, PPF, etc.). As shown in FIG. 4(b), when shredding a foaming material tray T, since the thickness of the tray T is relatively thick but soft, it is sufficient to define the cutting direction by forming a shallow groove 21 (the second groove).

[0022] That is, if the foaming tray T is shredded by cutting on a surface without a groove, in the case of a cutter that pulls and cuts (the previous patent), the cut surface sandwiches the side surface of the cutter and the object is also pulled, so it is necessary to hold the object. In this regard, since the rotary cutter C has a downward vector that also becomes the force to cut the object, the tray T can be cut efficiently without shifting.

[0023]

[0023] And, as a feature of the surface 10 having a groove for cutting the non-foaming tray T into pieces, there is a tactile sensation when applying force. Since the hardness of the target tray T and the cutting device D is similar, when the tray T is in close contact with the surface of the cutting device D, it is difficult for the hand to feel whether it has been cut. If it is too weak, it will not cut, and if it is too strong, it will cut the cutting board as well.

[0024]

[0024] On the other hand, in the cutting device D having the groove 11, the feeling of cutting is surely understood, and there is also a feeling of hitting the bottom surface 11b of the groove 11 when pushing it forward (this description is nothing but that the human hand has an excellent tactile sensation that can easily perform two actions: the feeling of cutting the object and the feeling of advancing while touching the bottom of the groove). It can also be said to be a jig that realizes this. In the home, in order to efficiently cut more than half of the plastic waste into pieces using both foaming and non-foaming materials of the food tray T, two surfaces 20 and 10 suitable for each are required.

[0025] (Effect) Next, the effects exerted by the cutting device D for the food tray of the present embodiment will be listed and described.

[0026] (1) As described above, the cutting device D for the food tray of the present embodiment includes a first surface 10 provided with a plurality of first grooves 11 having a first depth h1, and a second surface 20 provided with a plurality of second grooves 21 having a second depth h2 shallower than the first depth h1, and are integrally provided on the front and back. With such a configuration, when cutting food trays T made of various materials, while feeling through the tactile sensation that the food tray T has been cut, the cutting can be advanced. That is, by being able to surely feel the feeling of cutting through the hand, the food tray T can be efficiently cut without requiring unnecessary force.

[0027] (2) Further, the first surface 10 has a first recess 11 which is a first groove and a first convex portion 12 therebetween, and the second surface 20 has a second recess 21 which is a second groove and a second convex portion 22 therebetween. Since the back side of the first recess 11 is the second convex portion 22 and the back side of the first convex portion 12 is the second recess 21, the thickness of the member can be suppressed and resin molding can be facilitated, and the material can be used efficiently.

[0028] (3) Further, stopper walls 13 and 23 are formed on the extension lines of the starting points and ending points of the first groove 11 and the second groove 21, so that the rotary cutter C can be prevented from escaping and the damage to the table on which the shredding device D is placed can be prevented by floating the back surface.

[0029] (4) And the method for shredding a food tray is a method for shredding a food tray using any of the above-described food tray shredding devices D, and includes a step of placing a food tray T made of a non-foaming material on the first surface 10 and a step of shredding along the first groove 11 using a rotary cutter C. When shredding a tray T made of a relatively hard material that is not foaming in this way, by increasing the depth h1 of the groove 11, it becomes easier to feel that cutting has been performed.

[0030] (5) Further, the method for shredding a food tray includes a step of placing a food tray T made of a foaming material on the second surface 20 and a step of shredding along the second groove 21 using a rotary cutter C. When shredding a tray T made of a foaming and relatively soft material in this way, by making the depth h2 of the groove 21 shallow, the resistance during cutting can be reduced.

[0031] As described above, the embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and design changes that do not deviate from the gist of the present invention are included in the present invention.

[0032] For example, in the embodiment, the case where the stopper walls 13 and 23 are installed so as to surround the entire circumference has been described, but the present invention is not limited thereto, and the stopper walls 13 and 23 may be provided partially.

[0033] In addition, in the embodiment, the case where three first grooves 11, 11, 11 are provided on the first surface 10 and two second grooves 21, 21 are provided on the second surface 20 has been described, but the present invention is not limited thereto, and the number of grooves may be any number.
