It is appropriate that the first layer 130 is made of a corrosion-resistant material in order to suppress contamination or damage to the contents contained in the packaging container due to corrosion of the corrosive core layer 120.

In addition, since the first layer 130 is combined with the bonding layer 210 of the lead 200 below by heating, it is appropriate to be provided with a thermoplastic material. In order to satisfy these conditions, the first layer 130 may be formed of, for example, a polyethylene (PE) material that is a thermoplastic resin and has excellent corrosion resistance.

As shown in FIG. 3, the second layer 140 is formed on the center layer 120 so as to be symmetrical with the first layer 130 with respect to the center layer 120, and the body 100 ) Outside (indicated as'out' in FIGS. 3 and 4).

The second layer 140 is formed on the outermost outer shell of the packaging container, so that corrosion of the corrosive center layer 120 can be suppressed. In addition, since it forms the outer surface of the packaging container, it is appropriate to be provided with a material that can feel the aesthetic feeling in appearance. Therefore, in order to satisfy these conditions, for example, the second layer 140 may be formed of a varnish material.

If necessary, information on the contents may be displayed on the surface of the second layer 140, or a pattern or design, trademark information, and other contents may be printed to add an aesthetic feeling.

In addition, the body 100 may further include a third layer 160 and a fourth layer 170.

The body 100 is manufactured in the form of a flat plate in which the first layer 130 to the fourth layer 170 is formed on the center layer 120, and is then bent to form a circular, elliptical or polygonal cross section. It can be manufactured by attaching the ends to each other.

The third layer 160 may be formed between the center layer 120 and the first layer 130. The third layer 160 attaches the center layer 120 and the first layer 130 to each other, and together with the first layer 130, a packaging container due to corrosion of the corrosive center layer 120 Contamination or spoilage of the contents of the container can be suppressed.

Therefore, it may be appropriate to be provided with a material having strong adhesion and strong corrosion resistance so as to firmly couple the center layer 120 and the first layer 130 of materials different from each other.

In order to satisfy these conditions, for example, it is appropriate that the third layer 160 is formed of at least one of acrylic, epoxy, and vinyl resin. Of course, if the material satisfies the above conditions, the third layer 160 may be formed of a material other than the above-mentioned material.

The fourth layer 170 may be formed between the center layer 120 and the second layer 140. The fourth layer 170 attaches the central layer 120 and the second layer 140 to each other, and together with the second layer 140, the corrosion of the corrosive central layer 120 can be suppressed. have.

Accordingly, it may be appropriate to be provided with a material having strong adhesion and strong corrosion resistance so as to firmly couple the center layer 120 and the second layer 140 of materials different from each other.

In order to satisfy these conditions, for example, the fourth layer 170 is appropriately formed of at least one of acrylic, epoxy, and vinyl resin. Of course, if the material satisfies the above conditions, the fourth layer 170 may be formed of a material other than the above-mentioned material.

At this time, the third layer 160 and the fourth layer 170 may be formed of the same material or different materials.

The lead 200 may be coupled to the lead 200 at one opening of the body 100 to close the one opening. Meanwhile, the contents may be injected into the body 100 through the other opening of the body 100 (an opening opposite to the one opening). After the contents are injected, the other opening is closed with a separate cover (not shown).

The cover, unlike the lid 200, is provided so that the user cannot easily remove it from the body 100, so that the contents contained in the packaging container are not easily poured out of the packaging container due to the user's handling. Do.

The lead 200 is coupled to the curled portion 110 at the edge, and may include a bonding layer 210, a metal layer 220, and an outer skin layer 230. At this time, the surfaces of the first layer 130, which is the bonding portion of the body 100, and the bonding layer 210, which is the bonding portion of the lead 200, are brought into contact with each other, the lead 200 and the body 100 are heated, and the lead ( When 200) is compressed to the body 100, the first layer 130 and the bonding layer 210 may melt and be easily bonded to each other.

When the user opens the packaging container, when the user pulls the gripper 240 with an appropriate force, the first layer 130 and the bonding layer 210 are separated from each other, and thus, the lid 200 is separated from the body 100. Can be easily removed.

The lead 200 may be conveniently removed by the user using a hand or other tool, and it is necessary to be provided so as not to injure the user when the lead 200 is removed. Therefore, it is appropriate that the lead 200 is provided with a flexible material and thickness compared to the body 100 so as to be convenient and safe for the user. On the other hand, while handling the packaging container, it is also necessary to prevent the lid 200 from being damaged by a light external force from spilling the contents of the packaging container.

Therefore, in order to satisfy the above conditions, it may be appropriate to form the lead 200 by coating and laminating a layer of another material on a solid metal thin film. Accordingly, the lead 200 may be formed to include the bonding layer 210, the metal layer 220, and the outer skin layer 230.

The bonding layer 210 may be combined with the first layer 130 at the curled portion 110 of the body 100. As described above, the bonding layer 210 may contact the first layer 130 and be bonded to the first layer 130 by heating and pressing.

In addition, the bonding layer 210 is formed on the metal layer 220 to prevent the metal layer 220 from being corroded to contaminate or damage the contents of the packaging container, and conversely, the contents of the packaging container corrode the metal layer 220 Can be suppressed.

Since the bonding layer 210 is bonded to the first layer 130 by heating and pressing, it may be appropriate for the bonding layer 210 and the first layer 130 to be formed of the same material for easy bonding. . Accordingly, the bonding layer 210, like the first layer 130, may be formed of, for example, a polyethylene material.

The metal layer 220 may be formed on the bonding layer 210. Since the metal layer 220 is formed of a metal material, it is possible to effectively suppress the entire lead 200 from being damaged by an external force.

However, for the user's convenience and safety, since the metal layer 220 must be flexible, it is appropriate to be formed of a thin film having a thin thickness compared to the center layer 120 of the body 100. In addition, it is appropriate to be formed of a material having strong corrosion resistance to protect the contents of the packaging container. To satisfy these conditions, the metal layer 220 may be formed of, for example, a material including aluminum.

The outer skin layer 230 may be formed on the metal layer 220 so as to be symmetrical with the bonding layer 210 with respect to the metal layer 220. Since the outer skin layer 230 is provided on the outermost side of the lead 200 and serves to protect the metal layer 220, it is appropriate that the outer skin layer 230 is formed of a material having high corrosion resistance and high strength and hardness. To satisfy these conditions, the outer skin layer 230 may be formed of, for example, polyethylene terephthalate (PET).

In the embodiment, when the user opens the packaging container, since the lid 200 can be easily removed using a hand or a simple mechanism, the user's convenience can be improved.

In the embodiment, since the packaging container is sealed using the lid 200 of a flexible material, when the user opens the packaging container, it is effective to prevent the user from being injured by the sharp fracture surface of the conventional non-flexible metal sealing area. Can be suppressed.

In the conventional case, the packaging container has a flange protruding from one end of the packaging container opening to the inside or outside of the packaging container for sealing, and the sealing portion is attached to this flange by seaming or the like. In the embodiment, due to the above structure, by not performing the conventional flange formation and seaming processing, the production cost and production time of the product are saved compared to the conventional one, so that the productivity of the packaging container product can be improved.

In the embodiment, a simple process of forming the curl portion 110 and coupling the lead 200 to the curl portion 110 can secure sufficient sealing of the packaging container for product storage, thereby lowering the production cost of the product, Product productivity can be improved.

6 is a flowchart illustrating a method of manufacturing a packaging container according to an embodiment. The packaging container manufacturing method may include a preparation process (S100), a neck-in forming process (S200), a curling process (S300), an attaching process (S500), and a cutting process (S600).

In the preparation process (S100), the body 100 and the lead 200 are provided. As described above, the body 100 may be manufactured in a flat plate shape and then bent to have a circular, elliptical or polygonal cross section, and the side ends may be attached to each other.

In the curling process (S300), the curling portion 110 may be formed at one end of the body 100. The curl portion 110 may be formed by winding one end portion of the body 100 on which the neck-in 150 of the body 100 is formed toward the outside from the inside of the body 100 with respect to the body 100 provided in a hollow shape. Likewise, the curling process (S300) may be performed using the press processing factory value.

In the attaching process (S500), the body 100 and the lid 200 may be heated and pressed to attach them to each other. The first layer 130 of the body 100 and the bonding layer 210 of the lid 200 have plasticity by heating, and may be attached to each other, that is, combined by pressing, that is, pressing.

At this time, it is appropriate that the first layer 130 and the bonding layer 210 are heated to a temperature such that they are attached to each other by pressing, and therefore, the heating temperature of the first layer 130 and the bonding layer 210 is first It may be appropriately selected according to the material of the layer 130 and the bonding layer 210.

In this case, as shown in FIG. 5, the lead 200 may be coupled to the body 100 at an edge, that is, a portion where the curl portion 110 of the body 100 is formed. Due to this structure, the area of the portion where the lid 200 is coupled to the body 100 is considerably smaller than the total area of the lid 200, so that the user simply removes the lid 200 by hand to remove the packaging container. Can be opened.

In the cutting process (S600), the lead 200 may be cut to correspond to the shape of the body 100. In the cutting process (S600), after the attachment process (S500) is completed, the remaining unnecessary portions may be removed except for the portion where the lead 200 is coupled to the body 100.

At this time, the lead 200 may be cut into an appropriate shape with a cutting means so that the user can use it when opening the packaging container, thereby forming the gripper 240 that the user can hold by hand.
