DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tableware basket used for feeding, washing, drying, sterilizing, and storing tableware in a school or the like. The present invention also relates to a method for manufacturing a stackable metal basket and a method for manufacturing a handle.

[0002]

2. Description of the Related Art Heretofore, a basket made of metal such as stainless steel has been used as a tableware basket for meals, and the tableware is directly placed in the basket. In recent years, tableware materials have become
Traditional alumite and plastic products have been changed to reinforced heat-resistant glass and reinforced ceramic products, but conventional dishware baskets were used as they were.

[0003] Conventionally, a metal cage has been manufactured through various processes by various manufacturers. The metal cage is welded at intersections of constituent wires, and after forming a bottom portion, a vertical wire for the side is formed. Are considered to be almost the same.

[0004]

The tableware made of reinforced heat-resistant glass or porcelain ceramic has a higher quality at the time of eating compared with the tableware of the conventional material, but the edge is cut off at the time of washing and transportation. There was a risk of doing. In addition, when tableware made of reinforced heat-resistant glass or reinforced ceramic is placed in a conventional tableware basket, when it rubs against a stainless steel metal surface, dirt called a “metal mark” adheres to the tableware surface, and this dirt is removed. There was a problem that was difficult to remove.

[0005] Further, since tableware for feeding is usually handled roughly, it is required to have an impact strength in order to prevent breakage. In the case of dry sterilization, the tableware is usually kept at 100 ° C for about 1 hour ( Heat treatment at a maximum temperature of 120 ° C for 3 to 4 hours) Heat resistance and ventilation are required, and various conditions must be sanitary, such as not extracting toxic substances to handle tableware. There were various problems that had to be held.

Further, in the above-mentioned conventional method of manufacturing a tableware basket, a reinforcing wire frame is sequentially fitted mainly to the outside of the side vertical line (for example, in the order of a large wire frame at the upper part to a small wire frame at the lower part), and is appropriately adjusted. The height is fixed by welding. Therefore, the positioning is likely to be inaccurate, and at the time of product stacking, the line frame of the inner basket (upper basket) and the side vertical line of the outer basket (lower basket) fit tightly, making removal difficult. There was a risk of becoming. In addition, when the interior material is provided, if the upper end of the interior material is fixed to the border frame, there is a problem that the interior material may be obstructed during stacking. In addition, there were many products that did not take into account certain stoppers during stacking. In addition, gripping members in which a spring is wound in a cylindrical shape were widely used, but all of them are formed narrower than the handlebar, so that they slide in the axial direction during use and grip with the handle frame. There was a risk that an accident would occur if a hand was caught between the ends of the member.

[0007]

It is bent and fixed so as to be wound around the wire frame 4 side (FIG. 2D).

Next, a stainless steel metal wire is bent into a U-shape to form a U-shaped hand frame 8 .
To rod 8a, compresses fitted long elastic gripping member 9 of width than the width L of Hisagete rod 8a by compression instrument 24 (Figure 3 (a)). The gripping member 9 is formed by winding an elastic wire in order to form a large diameter at the center and small diameters at both ends, and is formed in a tubular spring shape. The compression of the gripping member 9 is released, and a stop rod 10 is erected and fixed in the opening of the U-shaped frame 8 to form a pallet 11 (FIG. 3B). The support 11 is formed wider than the conventional example so that one side can be gripped by both hands. The openings of the shanks 11, 11 are bent and movably attached to opposing positions of the edge line frame 4, respectively, to form a metal basket 12 (FIG. 4). In the above, the locking line frame 5 is bent more gradually than the edge line frame 4 and the reinforcing line frame 7. That is, at the corner of the metal basket 12, the corner 5a of the locking wire frame 5
Does not contact the side vertical line 3a formed by bending the inner metal wire 1a of the side vertical line 3 (FIG. 5).

Next, on the four peripheral edges of the bottom interior member piece 14 that can be attached to the bottom 2 of the metal basket 12, side interior member pieces 15, 16, 17, 1 that can be attached to the side of the metal basket 12, respectively.

Next, similarly, the metal basket 12 is similarly coated and coated with a covering material made of polyester resin, and the locking pieces of the porous interior member 21 are locked to the locking wire frame 5 of the metal basket 12. Meanwhile, the porous interior member 21 is provided inside the metal basket 12.
To form a tableware basket 22 for lunch (FIG. 1).

Next, the use of the present invention based on the above embodiment will be described.

A tableware made of reinforced heat-resistant glass or porcelain is put in the tableware basket 22 for feeding, and the tableware is transported, washed, dried, sterilized, and stored. At this time, since the edge of the tableware does not protrude outward from the hole 20 of the porous interior member 21,
There is no possibility that the tableware comes into contact with the metal wire or other metal product, and the possibility that the metal mark adheres to the tableware can be prevented.
Further, since the tableware does not come into contact with the metal wire, it is possible to prevent the edge from being chipped.

Further, a large number of holes 20, 20 are formed in the porous interior member.
Further, since the porous interior member is formed by bending a substantially cross-shaped aluminum plate, a gap is formed between the respective side interior members. Therefore, when washing dishes,
Draining is good, and ventilation can be ensured during drying and sterilization, so that drying and sterilizing time can be reduced.

When drying and sterilizing, usually at 100 ° C.
For about 1 hour (max. 3 to 4 hours at 120 ° C), covered with a covering material made of polyester resin that can be sterilized. During drying and sterilization, the resin melts and stains the dishes or ignites. It is possible to prevent a fire from occurring.

So you can hold it with both hands. Also in this case, there is no possibility that the hand is caught between the end of the grip member 9 and the U-shaped hand member 8. Furthermore, the gripping member 9 has a large diameter at the center, so that it is easy to grip.

Since the locking piece 19 is bent so that the tip 19a faces vertically downward, if the tableware 22 for feeding is turned upside down, the porous interior member 21 can easily be removed from the metal basket 12. . When attaching the porous interior member 21, only by lowering the porous interior member from above the metal basket 12, the locking piece 19 is engaged with the locking line frame 5, and the porous interior member 21 is attached to the metal basket 12. Can be attached to Therefore, it is convenient to remove dust entangled between the wires of the metal basket 12 and the holes 20 of the porous interior member 21 and to clean the metal basket 12 and the porous interior member 21 respectively.

When it is desired that the porous interior member does not easily come off, such as in a case where the tableware 22 for feeding is frequently inverted, the porous interior member 21 is replaced with the metal basket 12.
When the distal end portion 19a of the locking piece 19 is bent inward so as to wind the locking wire frame 5 (the distal end portion 19b of the locking piece shown in the dashed line in FIG. 7), the porous interior member 21 is attached. Does not come off the metal basket 12 easily.

When the tableware baskets 22 and 22a for feeding are stacked one on top of the other without placing any dishes therein, the stop line frame 6 of the upper tableware basket 22a engages with the locking line frame 5 of the lower tableware basket 22. Stop (FIG. 8). Therefore, the outside of the metal basket 12 of the upper tableware basket 22 is
Since it does not contact the inner surface of the porous interior member 21 of the lower tableware basket 22, there is no risk of damaging the surface of the porous interior member 21, and the two tableware baskets 22,
There is no danger that 22a will not leave as it is.

When the tableware 23, 23 is placed in the tableware baskets 22, 22a for feeding and stacked vertically, the handle 11 of the lower tableware basket 22 can be turned inwardly. The stop rod 10 abuts against the side vertical line frames 3b, 3b of the fulcrum 11 to limit the rotation of the fulcrum 11, and the fulcrum 11 stops at a substantially horizontal position. In this state, if the tableware basket 22a is stacked on the tableware basket 22 from above, the bottom of the tableware basket 22a on the upper side is placed on the handle 11 so that the tableware basket 22a on the upper side is placed. Tableware 23, 2 in lower tableware basket 22
There is no possibility of contact with No. 3 (FIG. 9).

In the above embodiment, the porous interior member 21 and the metal basket 12 were covered with the resin material.
It is possible to coat only the metal cage 12 without coating.
Although the resin material is made of polyester, other resin materials can be used as long as they do not extract harmful substances and can be heat sterilized. For example, silicone type, acrylic type, fluorine type, polycarbonate type, polysulfone type,
It is also conceivable to use an epoxy resin, a polyurethane resin or the like.

In the above embodiment, the hole 20 of the porous interior member is circular, but the tableware exposed from the hole 20 is
If the shape and size do not contact the wire of the metal basket 12,
An elliptical shape, a square shape, a slit shape or the like is also possible.
In the above description, when the maximum diameter or the maximum width of the hole 20 of the porous interior member 21 is about 20 mm, the tableware does not come into contact with each wire of the metal basket when the tableware is stored.

In the above-described embodiment, the porous interior member 21 is formed by bending a substantially cross-shaped aluminum plate. However, it is also possible to form the bottom interior member and the four side members separately. . Further, a stainless steel plate or another metal plate may be used instead of the aluminum plate.

In the above embodiment, the size, shape, and size of the vertical and horizontal heights of the metal basket 12 are determined by the shape of the tableware to be stored,
Various things can be considered according to the size and the number.
