Description

  The present invention relates to a method for manufacturing a container containing contents in which the container is filled with contents.

  In the manufacturing process of a container, the presence or absence of a pinhole may be test | inspected by applying a high voltage (for example, refer patent document 1). Containers manufactured through this inspection cannot be added with a large amount of antistatic agent to the container body due to restrictions on decoration, and the container body may be charged without being fully discharged. There was a problem that dust and the like easily adhere to the main body.

JP-A-9-203726

  This invention is made | formed in view of the said subject, and it aims at providing the manufacturing method of the container which can solve the subject accompanying charging of a container main body.

  The present invention is a method for manufacturing a container containing contents filled in a container, wherein a conductor is brought into contact with the contents filled in the container body before sealing, and the contents and the conductors are used to The object is achieved by providing a method for manufacturing a container containing contents in which the conductor is removed from the container body and the container body is sealed after the container body is neutralized.

  According to the method for manufacturing a container with contents according to the present invention, since charging of the container body can be suppressed, there is a problem associated with charging of the container body that a conventional container had such that dust or the like tends to adhere to the surface. Can be resolved.

  The present invention will be described below based on preferred embodiments with reference to the drawings.

  FIG. 1 shows the manufacturing process of the tube container with contents according to the first embodiment of the present invention. In this embodiment, first, as shown in FIG. The lid 3 is attached to the mouth / neck portion 21 (see FIG. 2), and the lid 3 is placed in the transport holder 4 with the lid 3 facing downward.

  As shown in FIG. 2, the container body 2 is a so-called tube container, and is formed with a mouth and neck portion 21 having a spiral at one end and a flat seal portion 22 at the other end. In the previous state, the seal portion 22 is open as shown in FIG. The content of the antistatic agent in the container body 2 is preferably 0.1% by mass or less in consideration of decoration. Examples of the antistatic agent to be contained include nonionic surfactants.

  The lid 3 is preferably made of a resin molded body containing an antistatic agent. Examples of the resin constituting the lid 3 include polypropylene and polyethylene. Examples of the antistatic agent included in the lid 3 include nonionic surfactants. The antistatic agent is preferably included in the lid 3 in an amount of 0.05 to 1.00% by mass, and 0.2 to 0.4% by mass in consideration of moldability, decoration suitability, and antistatic effect. More preferably.

  Next, as shown in FIG. 1B, the filling nozzle 5 for the contents 10 is inserted from above the container body 2 before sealing to fill the contents 10. When a predetermined amount of the content 10 is filled, the filling is stopped, and the filling nozzle 5 is pulled up and taken out from the container body 2.

  The content 10 to be filled in the container main body 2 may be anything that is not sufficiently filled up to the inside of the mouth-and-neck portion 21 at the time of filling, and has a viscosity that is high enough to prevent discharge on the lid 3 side.

  The content of the content 10 is not particularly limited as long as it does not damage the container body 2 in the above viscosity range, and examples thereof include face-wash foam, hair treatment, toothpaste, hand cream, makeup remover, and the like. .

  Next, as shown in FIG. 1 (c), the conductor 6 penetrates the contents 10 filled in the container body 2 to contact the contents 10, and the contents of the container body 2 are passed through the contents 10 and the conductors 6. Perform static elimination. Thereafter, the conductor 6 is pulled up and taken out from the container body 2.

  The conductor 6 is not particularly limited as long as it has conductivity that can discharge the container body 2 through the content 10 when it contacts the content 10 and does not affect the quality of the content 10. . Examples of the conductor 6 include metals such as copper and iron. The form of the conductor 6 is not particularly limited as long as it can be taken in and out without damaging the container body 2.

  Next, as shown in FIG. 1D, the air nozzle 7 is inserted into the container main body 2, and hot air is blown from the air nozzle 7 toward the inside of the seal portion 22 to be heated. Then, the air nozzle 7 is retracted, and the sealing portion 22 heated by the sealing device 8 is pressure-bonded and sealed as shown in FIG.

  As described above, in the method for manufacturing the container 1 of the present embodiment, the conductor 6 is inserted into the content 10 after the content 10 is filled. Therefore, even if the container body 2 is charged after the inspection, the content 10 The charge is removed through the container body 2, so that the charging of the container body 2 can be reliably removed. Therefore, it is possible to eliminate various problems that conventional containers have such that dust or the like easily adheres to the surface of the container body 2.

  FIG. 3 shows a container manufacturing method according to the second embodiment of the present invention. In this figure, portions common to the method for manufacturing the container 1 of the first embodiment shown in FIG. Therefore, the description of the first embodiment is applied as appropriate to portions that are not particularly described.

  The manufacturing method of the container according to the second embodiment shown in FIG. 3 is the same as that of the first embodiment except that the process of bringing the conductor 6 into contact with the contents 10 and removing the electricity from the container body 2 is different. That is, the manufacturing method of the container according to the present embodiment is such that the contents 10 as shown in FIG. 3B are viewed from above the container body 2 before sealing arranged as shown in FIG. The filling nozzle 5 and the conductor 6 are inserted, the contents 10 and the conductor 6 are brought into contact with each other while the contents 10 are filled in the container body 2, and the container body 2 is neutralized through the contents 10 and the conductor 6. After filling the contents 10 and neutralizing the container body 2, the filling nozzle 5 and the conductor 6 are taken out from the container body 2. The subsequent processes shown in FIGS. 3C and 3D are the same as the container manufacturing process according to the first embodiment.

  The container manufacturing method of the present embodiment can surely remove the charge of the container body 2 even when the container body 2 is charged after the inspection of the container body 2, as in the method of manufacturing the container 1 of the first embodiment. Therefore, it is possible to eliminate the problems associated with the charging of the container main body that the conventional container has, such as dust easily attaching to the surface of the container main body 2. Moreover, in the manufacturing method of this embodiment, the filling of the contents and the charge removal of the container body 2 can be performed simultaneously, so that the manufacturing process can be simplified.

The present invention is not limited to the embodiments described above.
For example, in the above-described embodiment, the lid 3 is attached to the mouth / neck portion 21 of the container main body 2 by screwing. However, the manner of attaching the lid 3 to the mouth / neck portion 21 is not particularly limited. For example, it is possible to adopt a form in which the lid is fitted to the mouth / neck portion of the container body by fitting, or a form in which the lid is opened / closed via a hinge.

  Moreover, in the said embodiment, although the cover body 3 was set as the form with which the mouth neck part 21 of the container main body 2 is attached by screwing, it can also be used for a drive-in type cap.

  The manufacturing method of the container with contents of the present invention can be applied to containers other than the tube container as in the above embodiment.
