BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cup ramen, a pudding, a coffee used in a car, ice cream, and other tools used for eating and drinking, and a method for producing the same.

[0002]

2. Description of the Related Art Conventional food and drink tools include synthetic resin forks and spoons used for eating and drinking cup ramen, pudding, coffee for in-vehicle sales, ice cream, etc. There is also a spatula made of synthetic resin that is used when cutting or eating Japanese sweets such as.

[0003]

The above-mentioned conventional eating and drinking tools have the following problems. When these tools are shrink-packed together with products such as cup ramen and pudding with a heat-shrinkable film, these tools are deformed by the heat of the heating furnace. Further, the heat of the heating furnace causes the heat-shrinkable film and these tools to be heat-welded. In the case of a product made of synthetic resin, if it breaks during transportation or use, the tip becomes sharp and it is dangerous. In manufacturing these tools, an expensive injection molding machine and an expensive die for multi-piece production are used, resulting in high cost. The expensive multi-cavity mold cannot easily be redesigned, and another metal mold must be newly created when the design is changed, which also increases the cost. The life of the mold reduces the quality of the tool. For example, it is common to use a split mold, but there is a gap on the mating surface, a burr is generated on the tool, and in consideration of safety, it is necessary to spend labor and eliminate the burr. In addition, it is necessary to regularly modify or make new molds. Therefore, the present invention has no problems of thermal deformation and heat welding even in shrink packs, and is safe, certain quality is secured, the manufacturing cost is low, and the cost is low even when the design is changed. The challenge is to provide.

[0004]

In order to solve the above-mentioned problems, the present invention is to scoop and scoop foods and drinks at one end of a rod-shaped body 10 made of a fibrous member made of wood / paper material. Alternatively, a spatula portion 11, a scooping portion 13, a fork portion 16 or a knife portion 19 made of a paper sheet for cutting or the like is provided. Further, paper grip portions 14 and 17 are provided on the other end of the rod-shaped body 10. As a tool manufacturing method, a rod-shaped body 1 made of a fibrous member made of wood or paper

Embodiments Embodiments will be described below with reference to the accompanying drawings. The accompanying drawings are all embodiments of the present invention. Figure 1
FIG. 1 is an overall perspective view of a stirring tool for coffee, tea, etc., and 10 shows a bar-shaped body. This bar-shaped body 10 is formed by densely winding a high-quality paper having a width matching the length of the bar-shaped body. It is a bar. At this time, it is good for the high-quality paper to be coated with an adhesive on the inner side of the portion including the outermost peripheral edge and to be fixedly adhered to the portion wound on the inner side, but the adhesive is applied to about one outermost periphery. The adhesive may be applied, or the adhesive may be applied to the entire range from the innermost circumference to the outermost circumference. Further, according to another manufacturing method, it may be obtained by applying an adhesive to a belt-shaped paper having an appropriate width, twisting it, and molding or heating the surface. Further, when the diameter is to be large, the paper may be wound by spiral winding or flat winding which is a usual method for manufacturing a paper tube. Therefore, the rod-shaped body 10 may be hollow as long as it can maintain an appropriate strength. As described above, when the rod-shaped body 10 is made of paper, its manufacturing method can be appropriately changed, and even if it is broken during transportation or use, the broken portion does not become sharp, It is also extremely advantageous in terms of safety. As another example of the rod-shaped body 10, a wooden rod may be used.

A roughly flat spatula portion 11 is provided at one end of the rod-shaped body 10. The spatula portion 11 is made by punching into a substantially semi-elliptical shape by superimposing two cup base papers on both sides of one end of the rod-shaped body so as to sandwich the one end of the rod-shaped body 10. The shape of the spatula portion 11 can be arbitrarily determined. Here, the spatula portion 11 may be composed of one cup base paper, and in that case, one end of the rod-shaped body 10 is
A sheet of cup base paper is placed, and a backing paper for fixing and adhering is adhered from the back surface so that one end of the rod-shaped body 10 is sandwiched and the spatula portion 1

It was punched out. Therefore, it can be manufactured in the same manner as the spatula portion 11 of the stirring tool described above, although the shape is different. However, in this example,
In consideration of the strength of the knife, the knife portion 19 must be constructed by polymer-bonding two cup base papers. Further, this stick-shaped knife can be used not only for cutting yokan, cake, etc., but also for sticking the cut yokan, etc. and using it like a fork.

Next, a method for manufacturing this eating and drinking tool will be described. This eating and drinking tool can be manufactured by a single-cooking method, a continuous manufacturing method, or a batch-type manufacturing method, and a method of appropriately combining the following can also be considered. The method of (1) is a method of manufacturing each eating and drinking tool by hand. Is a method in which the bar-shaped body 10 is continuously transferred and the functional portions for eating and drinking such as the spatula portion 11 are sequentially joined to the ends of the bar-shaped bodies 10. In this case, the eating / drinking functional part may be cut into a desired shape in a separate step, and this step may be cut continuously, or an appropriate number may be punched at a time.
Further, when cut, it is possible to simultaneously apply a press work to give a curved shape such as a scooping portion. Alternatively, when joining the eating and drinking function part to the end of each rod-shaped body 10, press working may be performed. Further, after the joining, it may be cut again into a better shape, or may be pressed. Is a method in which the rod-shaped bodies 10 are arranged in an appropriate number and joined to an uncut paper material such as a band-shaped paper material, and then these are simultaneously cut into a desired shape. Then, at the same time as this cutting, press working can be performed to give a curved shape such as a scooping portion. Alternatively, when joining the eating and drinking function part to the end of each rod-shaped body 10, press working may be performed. further,
After cutting, it may be cut again into a better shape or may be pressed. Is an appropriate combination of the methods of, for example, in the method of, only the joining, such as sequentially joining the uncut paper material such as the belt-shaped paper material while continuously transferring the rod-shaped body 10 is performed. The cutting may be carried out continuously and the cutting may be carried out in a batch manner. After the joining is performed by the reverse method, the pieces may be sequentially cut while sequentially flowing.

Next, a more preferable method for manufacturing the above-mentioned eating and drinking tool will be described with reference to FIGS. 9 to 12.
For convenience of explanation, a spoon will be described below as an example. In FIG. 9, a large number of paper rods 10 are aligned and supported on a conveyer at regular intervals, and a belt-shaped paper 20 made of cup base paper is transferred to one end of one that is sequentially conveyed in harmony with the conveyance of the rods 10. FIG. 3 is an explanatory diagram illustrating that replenishment is performed, and in the same manner, strip-shaped paper 21 for the grip portion made of cup base paper is replenished to the other end of the rod-shaped body 10 in harmony with the conveyance of the rod-shaped body 10. The belt-like papers 20 and 21 are waterproofed on their surfaces, and the surface thereof in contact with the rod-shaped body 10 is previously coated with an adhesive that can be adhered by heat-sealing. These strips 20 and 21 will be used later for the rod-shaped body 10.

Folded.

FIG. 10 is an explanatory diagram showing a state in which the band-shaped papers 20 and 21 arranged at both ends of the rod-shaped body 10 are folded in two along the crease lines shown in FIG. 9 and heat-sealed. . Here, it is also possible to form the scooping portion 16 of the spoon by press molding at the same time as heat sealing. Performing the heat-sealing process and the press-molding process at the same time increases the shape-retaining force of the scooping portion 16 as compared with performing the heat-sealing process and then the press-molding process. After completion of this heat-sealing process or heat-sealing process and press-molding process, it is conveyed to the next step.

FIG. 11 shows the belt-shaped paper 2 conveyed from the previous step.
It is explanatory drawing which shows the process of punching out the part of 0,21. The strip 20 for forming the scooping portion 13 is punched into the shape of the scooping portion 13 of the spoon. At the time of this punching, it is possible to leave a fold portion at the tip of the scooping portion 13, and by doing so, the strength of the tip of the scooping portion 13 can be increased. When the heat sealing process and the press forming process are not performed at the same time in the previous process, the press forming process of the scooping portion 13 of the spoon is performed after the punching process. On the other hand, the band-shaped paper 21 forming the handle portion 14 is
Only heat sealing is performed in the previous step, and only punching into an appropriate shape is performed in this step. here,
The handle portion 14 can also be processed in the same manner as the scooping portion 13, and can be appropriately press-formed. Upon completion of this step, the spoon, which is one of the eating and drinking tools of the present invention, is sequentially completed and is conveyed to the packaging step of the next step.

FIG. 12 is an explanatory view of the packaging process, in which the spoon 30 is sequentially placed on the strip-shaped packaging film 25, the strip-shaped packaging film 25 is folded in two, and the spoon 30 is interposed between the films. In addition, heat seal three sides of the film so that the spoon 30 is packed (the shaded area in the figure), and finally, separate the packed spoons 30 one by one. The packaging is completed by inserting the perforations 27 in the heat-sealed portion in parallel with each spoon 30 so that the packaging can be performed. After that, the product is shipped through a boxing process.

The method for manufacturing a spoon, which is one of the eating and drinking tools of the present invention, has been described above. The strip 20 for forming the scooping portion 13 is formed by folding one strip 20 as described above. Instead of using two strips of paper 20,
The rod-shaped body 10 may be replenished so as to be sandwiched at one end, or one strip 20 may be used to replenish the rod-shaped body 10 at one end and the backing may be used to replenish the strip 20. 1
It may be fixedly bonded to 0. On the other hand, the band-shaped paper 21 for the handle portion
Similar to the scooping portion 13, two strips of paper may be used, or one strip of paper may be used and fixed and adhered by a backing paper.

On the other hand, in the case of the method for manufacturing the stirring tool, the step of press molding is not always necessary, but the surface of the spatula portion 11 is made smoother by applying pressure pressing at the same time as heat sealing. In addition, the shape retaining force is further increased. In the case of the fork manufacturing method, it is almost the same as the above-mentioned spoon manufacturing method, except that the punching shape in the punching step is different and the bending processing in the press forming is different. Furthermore, in the case of manufacturing a stick knife, it is almost the same as the stirring tool, but in the case of this knife,
In order to increase the strength, it is preferable to perform pressure press molding at the same time as the heat sealing process. It should be noted that it is also possible to carry out the present invention with respect to eating and drinking utensils other than those specifically exemplified, and in that case, it goes without saying that a manufacturing method suitable for each utensil is appropriately selected from the above methods and adopted. It is possible. As the paper sheet used for the eating / drinking functional portion and the grip portion, paper materials other than the cup base paper can be appropriately used. Further, in the present invention, the paper means a material whose main material is paper, and for example, a composite material whose main material is paper obtained by laminating a synthetic resin film or a metal foil on the front and back surfaces of the paper is used. Alternatively, suitable colors and patterns may be applied by printing or the like. The embodiments of the present invention have been described above, but the present invention can be modified in various ways within the scope of the claims.
