[Industrial applications]

 The present invention mainly relates to a food container lid used in an instant food automatic packaging line.

[0002]

[Problems to be solved by conventional techniques and devices]

 Conventionally, an apparatus as illustrated in FIG. 1 has been used as an automatic packaging line for instant foods. This device will be described with reference to the same drawing. A lid using a suction cup for a food container body 2 that is placed on a belt conveyor 1 that moves at about 20 m / min and that contains snack noodles and the like inside. The lids 4 sucked one by one by the body feeding robot 3 are fed onto the container main body 2 and then passed under the nip rolls 5 provided on the downstream side of the belt conveyor. The one that fits into the container body is used. However, in the above-mentioned robot lid-using robot using the suction cup, the lid feeding device is complicated and expensive, and there are many failures. In recent years, lids with a wide variety of shapes have been used in consideration of functionality and design, but if the shape of the lid changes in this way, the position of the suction cup and the timing of separating the lid from the suction cup can be changed. It was necessary to change the settings, which was troublesome.

In order to solve these problems, an automatic packaging line for instant foods is designed such that a lid body is fed from a robot lid body supply device using a suction cup as described above and a lid body passes over an inclined lid body feed guide line. It is moving to a device that supplies it onto the container body that flows on the conveyor.

An example of the above automatic packaging line will be described with reference to FIG. As shown in the figure, the packaging line includes a container body transport line 6 and a lid supply guide 7, a separate supply device 8 for supplying the stacked lids 4 one by one onto the supply guide 7, and a container body. 2 and nip rolls 5 for fitting the supplied lid to the main body. The lids 4 stacked in the separating and feeding device 8 are dropped one by one into the lid feeding guide 7 by the separating and feeding device 8, pass through the guide 7 and flow through the container body carrying line 6. It is supplied to match the opening of the incoming container body. At this time, there are a method of supplying the lid 1 to the container opening by utilizing gravity due to the inclination of the lid supply guide 7 and a method of using a movable roller to forcibly supply the lid. In addition, it is preferable to provide a lid supply stopper (not shown) on the lid supply guide 7 for finely adjusting the timing of feeding the lid. Usually, it suffices to match the container body with the timing of supplying the lids of the separating and supplying device 8 one by one. The lid body fitted and supplied to the opening of the container body by the above process is passed under the nip roll 5 provided on the downstream side of the transfer line, so that the lid body fits into the container body. .

On the other hand, food such as yakisoba which requires hot water drainage in an instant food container has a lid provided with a drainage outlet, and the shape of the lid, especially the hot water outlet has many Has been devised. Generally, the hot spring outlet is divided into two, one by the tongue and the other by the bulge. Regarding the rate of hot water discharge, the bulging portion seems to be superior, but there is a problem in that the contents such as noodles and condiments are not completely separated from the hot water. There is also a safety issue due to the fact that the hot water outlet is on the bottom surface and the hot water outlet cannot be seen, and the lid opens because of the high hot water discharge rate. It is excellent and the tongue method is the mainstream. Therefore, at present, most of the automatic packaging lines that use the slanted guide line to supply the lid having the drainage outlet by the tongue piece are used.

However, in the combination of the above-mentioned slanted guide line automatic packaging line and the lid body having the hot water outlet by the tongue, the tongue piece of the lid is caught by the slanted guide line, and the lid feeding operation is interrupted. However, there was a drawback that the tongue had an upward shape habit as a result of the tongue being caught by the guideline. In this way, the lid body in which the tongue piece is bent back and the hot water outlet is opened is not preferable when the noodles are returned with hot water. Further, the conventional hot water outlet using a tongue piece is not preferable for safety because it causes a problem that hot water is discharged toward the upper surface of the lid at the initial stage of hot water drainage operation. In addition, although shrink film packaging is performed when the final product is used, there is a drawback that the film is torn by the tongue piece.

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned conventional problems, and is a food container that is supplied so as to match the opening of the container body that passes through the lid supply guide and moves on the container body transport line. In the lid of the tongue, the tongue does not get caught on the slanted guideline, and the tongue does not get caught on the slanted guideline when the lid is supplied, and the tongue does not have a tendency to open. The purpose is to supply a lid for a food container that will not be released toward the top of the lid. That is, the lid of the food container of the present invention is characterized in that it has a tongue-shaped hot water outlet on the upper surface of the peripheral edge of the lid, and the hot water outlet is located in a recess provided in the peripheral edge of the lid.
