BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for processing a container, and more particularly to a step of filling a semi-finished product container with contents, a sealing process by heat-sealing an opening end, labeling of a semi-finished product container wall or characters. The present invention relates to a method for positioning a semi-finished product container in a series of processing steps such as a graphic printing process until a container is finally completed.

2. Description of the Related Art Generally, starting with molding, printing or labeling various character figures such as product names and uses on the molded container body, or the paste-like content is put into the container body as such a semi-finished product. In a series of processing steps such as filling and filling, and then sealing this filling port by a heat welding method, etc., the container body must be positioned each time in order to perform the required work at the required container position. It was done.

Positioning of such a container body is conventionally performed by
This was done by providing a reference mark at an appropriate place on the container body. That is, as an example of this work, for example, a cap is attached to the mouth and neck of a semi-finished tube container or the like, and after the contents are injected and filled from the hem opening end before sealing by heat sealing or the like. The hem open end is sealed by heat sealing.

By this heat sealing, the circular hem opening is flattened, so that the tube container has the front side and the back side only at this time. That is, in other words, since the front side and the back side are formed on the tube container when the hem opening end is heat-sealed, it is necessary to clearly determine the front side and the back side in advance and heat seal the hem opening end. If this is not done, for example, the characters and graphics printed on the wall surface of the tube container will not come to a certain position.

Therefore, as a conventional confirmation means, a positioning mark is provided in the vicinity of the hem opening end to be sealed. This kind of mark is usually called "photoelectric tube mark" or "I mark", and it is customary to mark it by means such as printing at the stage of a semi-finished product container.

[0006]

However, in the case of such a mark, the mark provided on the container body remains even after the completion of each processing step such as filling the contents and sealing the opening end to obtain a finished product. Because of marking by printing, etc., it cannot be peeled off and remains in the container as it is. Therefore, the appearance as a commercial product is impaired.

If the mark for the positioning reference is enlarged for the sake of confirmation, the appearance is further reduced. In addition, there is a circumstance that it is difficult to confirm if the mark display is made as small as possible by giving due consideration to this appearance. Therefore, it is necessary to remove the positioning reference mark from the wall surface after the finished product, that is, the finished product container. However, since the conventional positioning reference mark is provided by printing or the like as described above, the work of removing it is very troublesome, and this is a factor that reduces productivity, and improvement thereof is desired. It was

An object of the present invention is to solve the above-mentioned conventional problems. A positioning reference mark is attached to a semi-finished product container, and the necessary processing work is performed by using this positioning reference mark. The final object is to provide a container processing method for removing this positioning reference mark from a finished product container.

[0009]

The present invention is a container processing method, and has the following constitution in order to solve the above-mentioned technical problems. That is, according to the container processing method of the present invention, the positioning reference mark 3 is detachably provided on the semi-finished product container 1 at the initial stage of the container working process, and the semi-finished product container 1 is processed by using the positioning reference mark 3 in the working process. Positioning control at a predetermined position in each step of, and after the processing steps are completed and the semi-finished product container is formed on the finished product container, the positioning reference mark 3 is peeled off from the wall surface of the finished product container. It consists of

[0010]

According to the container processing method of the present invention, since accurate positioning control is performed on the manufactured semi-finished product container 1 in various subsequent processing steps, the wall surface of the semi-finished product container is started at the initial stage of a series of processing steps. A positioning reference mark is detachably provided on the. "Providing the positioning reference mark so that it can be peeled off" means, for example, a sticker paper on the front surface of which characters or patterns to be used as the positioning reference mark are printed, and a peelable adhesive is applied to the back surface of the sticker paper. It means something that can be easily peeled off with.

By utilizing the positioning reference mark 3 as described above, the semi-finished product container 1 is placed at the most preferable position in each processing step. When the semi-finished product container 1 is position-controlled at a predetermined position in each processing step by using the positioning reference mark 3 as described above, appropriate processing is performed in each step, and when this series of processing steps is completed. The function of the positioning reference mark 3 is finished, and thus the positioning reference mark 3 remaining on the wall surface of the finished product container is peeled off.

[0012]

EXAMPLES The container processing method of the present invention will now be described in more detail with reference to the examples shown in the drawings. 1 and 2 show respective processing steps in a container processing method according to an embodiment of the present invention. The container 1 used in this embodiment is a tube container as shown in FIG. However, the container targeted by the present invention is not limited to such a tube container, and other containers include plastic containers and bottle containers.

[0013] The tube container 1 filled with the paste-like contents is a semi-finished product, and the surface of the tube container 1 is labeled or silk-printed with the product name, use, usage, advertisement display and the like. At this stage, the hem of the tube container 1 is in an open state as a filling and filling port for the contents as shown in FIG. 1, and the positioning reference mark 3 can be peeled off near the hem opening end 2. It is provided in. The positioning reference mark 3 means, for example, a seal having a character or a pattern to be the mark printed on the front surface thereof and a pressure-sensitive adhesive which can be peeled off is applied to the back surface thereof. There is. However, the material of the seal forming the positioning reference mark 3 is not particularly problematic.

In the step of injecting and filling the contents into the tube container 1, as shown in FIG. 1, a cap 4 is attached to the mouth and neck of the tube container 1, and the tube container 1 is attached.
Is turned upside down and the cap 4 is supported and fixed to the filling line 5. As a result, the hem opening end 2 of the semi-finished tube container is located at the upper part, and as a result, the contents are injected and filled from the hem opening end 2.

After the filling is completed, the hem opening end 2 of the tube container 1 is heat-sealed by a heat welding method or the like in the next sealing step, whereby the tube container 1 is hermetically closed. By this heat sealing, the circular hem opening 2 becomes flat as described above, and therefore the tube container 1 has the front side and the back side only at this time. However, the product name and the like are already displayed on the tube container 1, and therefore the front side and the back side are already determined, and the hem opening end 2 must be heat-sealed along this.

Therefore, when the tube container 1 is completed, the wall surfaces on the front side and the back side are distinguished by using the positioning reference mark 3. For example, the positioning reference mark 3 is read by a position confirmation means such as a position detection sensor, whereby the tube container 1 is positionally controlled and fixed in a predetermined direction, and then the heat sealing of the hem opening end 2 is started.

As shown in FIG. 2, when the tail end seal portion 6 is formed by sealing the hem opening end 2 by heat sealing and the filling of the contents is completed, the positioning reference mark 3 is formed.
Is easily peeled off from the tube container 1. In many cases, the products are sent to the packaging process at this stage. Therefore, in the process of filling the tube container 1 with the contents or the process of heat-sealing the hem opening end that performs the filling, the positioning reference mark releasably attached to the wall surface of the tube container 1 is used. Since the tube container 1 is positioned and controlled at a predetermined position, appropriate processing can be performed in each process.

When the series of processing steps are all completed, the positioning reference mark 3 which has served its purpose can be easily peeled off from the wall surface of the container, so that the appearance as a commercial product is not damaged. Further, since the positioning reference mark 3 can be easily peeled and removed from the wall surface of the tube container 1 in this manner, it is not necessary to consider the problem of the appearance of the product. Therefore, since a relatively large positioning reference mark can be used, the detection device can be used. The problem of erroneous detection and the difficulty of seeing by the operator is solved, and the efficiency of the machining process can be improved.

[0019]

As described above, according to the container processing method of the present invention, the positioning reference mark is detachably provided on the semifinished product container at the initial stage in the series of processing steps until the container is completed, and this positioning is performed. Since the reference mark is used to control the positioning of the semi-finished product container at a predetermined position in each step of the processing steps, it is possible to perform appropriate processing in each step.

Moreover, when all of the series of processing steps are completed, the positioning reference mark 3 that has finished its function can be easily peeled off from the wall surface of the container, so that the appearance as a commercial product is not damaged. Further, since the positioning reference mark 3 can be easily peeled and removed from the wall surface of the tube container 1 in this manner, it is not necessary to consider the problem of the appearance of the product. Therefore, since a relatively large positioning reference mark can be used, the detection device can be used. The problems of erroneous detection and stigmatization by the operator are also solved, and the efficiency of the machining process can be improved.
