2. Description of the Related Art A conventional egg container, as shown in the perspective view of FIG. 4, is composed of a body portion 61, a lid portion 62, and a connecting portion 63 connecting these two portions in a bendable manner. The synthetic resin sheet is integrally formed by vacuum molding or blow molding, and the body portion 61 and the lid portion 62 are provided with a plurality of concave portions 65 and flange portions 69 into which the eggs partitioned by the partition wall 64 are inserted. .

After inserting eggs into the respective recesses 65 of the body portion 61, the lid portion 62 is bent through the connecting portion 63, and the flange portion 69 facing the connecting portion 63 is stapled or heat-sealed to seal. It has stopped.

In such a conventional egg container, there is no suitable place to attach the label, and there is no device for automatically attaching the label. Therefore, a small indicator indicating the producer or quality of the egg is displayed. A piece of paper was enclosed with the egg. However, this small piece of paper is wrinkled, and it is difficult to check the content displayed on the piece of paper.Consumers should select only the egg size and purchase it without considering the producer or quality. There is.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, an egg container 6 to which a label is attached by the apparatus of the present invention is formed by vacuum-molding or blow-molding a thin synthetic resin sheet and separating a plurality of eggs from each other. The body part 61 includes a body part 61 and a lid part 62 which are integrally formed via a foldable connecting part 63 so as to hold, and a body part 61 has a partition wall so as to form an egg holding space in a closed state. A plurality of recesses 65 partitioned by 64 are provided, and a conical or pyramidal protrusion 67 is formed in the lid portion 62 at a position facing the intersecting portion 66 of the partition wall 64 of the body portion 61. The periphery of the portion 67 forms a flat surface 68.

On the other hand, a unit of label 5 indicating the producer and quality, which is attached to the inside of the flat surface 68 of the lid portion 62.
2 is repeatedly printed on a long synthetic resin film 51 as shown in FIG. 2, and partition marks 52 are printed between unit labels. And synthetic resin film
The shape of each label 5 punched out from 51 has a contour 54 having substantially the same shape as the flat surface 68 of the lid portion 2 of the egg container 6, and a hole having the same shape as the base of the conical or pyramidal protrusion 67. 53 is open.

As shown in the plan view (a) and side view (b) of FIG. 3, the apparatus for attaching a label to an egg container according to the present invention includes a conveyor 1 for transferring egg containers 6 one by one, and a conveyor 1 during transfer. Temporarily stop the egg container 6 of the
Adhesive applicator 2 for applying adhesive to the four corners of 68, and one label 5 is punched out from synthetic resin film 51 one by one, and the label 5 is dropped on the flat surface 68 of egg container 6 in which it is temporarily stopped. It is provided with a label punching device 3 and a label pressing device 4 which temporarily stops the egg container 6 being conveyed and presses the dropped label 5 onto the egg container 6 to adhere it.

The adhesive coating device 2 has four nozzles 21 for dropping the adhesive while the movement of the egg container 6 is temporarily stopped by a stop piece protruding on the conveyor 1, and to each of these nozzles 21. It is composed of a pump that pushes out the adhesive in a fixed amount.

The label punching device 3 is controlled by the output of a sensor for detecting the partition mark 52 printed on the long synthetic resin film 51, and the synthetic resin film 51 wound on the reel 31 is separated by the interval between the partition marks 52. Only while intermittently feeding and punching out the synthetic resin film of the scrap 55 punched out, a synthetic resin film feeding device consisting of a reel 32 and a hole 53 into which the base of the protruding portion 67 is inserted while the synthetic resin film 51 is stopped. The first punching device for punching and then the flat surface 68 of the egg container 6 by punching out the contour 54 of the label.
The punching operation is synchronized with the arrival of the egg container 6 conveyed by the conveyor 1.

The label pressing device 4 is a hollow frame 41 in the shape of a label that can be vertically moved up and down, and an elastic material 42 such as sponge or rubber is attached to the lower surface thereof. The label 5 is configured to be pressed onto the flat surface 68 of the egg container 6 to which the adhesive is applied. .

The egg containers 6 are placed one by one on the conveyor 1 in an open state and conveyed. The egg container 6 is the adhesive application device 2
At that time, the stop piece protrudes to temporarily stop the egg container 6, and the four nozzles 21 are simultaneously lowered to the four corners of the flat surface 68 of the egg container 6, and then the pump is operated to bond a certain amount. The agent is applied and the four nozzles 21 rise. Then, the stop piece is retracted, and the egg container 6 is conveyed to the label punching device 3 by the conveyor 1.

In the label punching device 3, first,
The hole 53 into which the base of the projecting portion 67 of the egg container is punched is punched by the first punching device, and when the egg container 6 is conveyed, the contour 54 is punched by the second punching device 33 and When the label is formed and dropped on the flat surface 68 of the egg container 6, the hole 53 of the label 5 slides down using the slope of the conical or pyramidal protrusion 67 as a guide. Is automatically positioned.

Next, when the egg container 6 is conveyed to the label pressing device 4, the egg container 6 is temporarily stopped and the hollow frame 41 having the shape of the label is lowered, and the lower surface thereof is lowered. The label 5 can be adhered to the flat surface 68 of the egg container 6 coated with the adhesive by pressing the elastic material 42 such as sponge rubber attached to the label 5 onto the label 5.

The egg container 6 to which the label 5 is attached through such a series of steps is carried to a hopper by a conveyor and stacked.

When packaging an egg from the egg container thus obtained, the egg is put into each recess 65 of the body part 1,
The lid portion 62 may be bent through the connecting portion 63, and the flange portion 69 facing the connecting portion 63 may be stapled or heat-sealed for sealing. No need.

Further, it is convenient for distribution that the label 5 displays a bar code (POS mark) in addition to the producer and the quality.

[0020]

As is clear from the description based on the above embodiments, according to the apparatus for attaching a label to an egg container of the present invention, a label indicating the producer and the quality is automatically displayed on the lid portion of the egg container. Can be pasted. Therefore, the egg container to which this label is attached allows the consumer to purchase the egg after confirming the producer and quality, and moreover, since the label is attached to the inside of the lid part,
Does not come off or break during handling.
