Abstract

In a film packaged body (11) formed by superimposing a pair of film molded articles (1) of the present invention, wherein the film molded article (1) in which a plurality of concave or convex embossed portions (3) disposed apart from each other are formed on a surface (2a) of a film (2), wherein the film (2) is made of a plastic material capable of adding a shape according to plastic deformation, wherein the plurality of embossed portions (3) are disposed on the surface of the film (2) to form an enclosed region (4) surrounded by the plurality of embossed portions (3) and imaginary lines (4a) that connect the plurality of embossed portions (3) is formed, and the plurality of embossed portions (3) are disposed at four areas on the surface (2a) of the film (2) to form the enclosed region (4) with rectangular shape, when an object is packaged by the film molded article (1), the plurality of embossed portions (3) and imaginary lines (4a) forming the enclosed region (4) are freely folded according to a shape or a size of the object to be packaged (5), and become a concave accommodating portion (4A) for accommodating the object to be packaged (5), wherein an object to be packaged (5) is disposed in the enclosed region (4) formed on the film molded article (1), the pair of film molded articles (1) are superimposed to cover the object to be packaged (5), and the object to be packaged (5) is a lithium ion secondary battery cell.

First claim

1 . A film packaged body formed by superimposing a pair of film molded articles, wherein the film molded article in which a plurality of concave or convex embossed portions disposed apart from each other are formed on a surface of a film,
wherein the film is made of a plastic material capable of adding a shape according to plastic deformation, wherein the plurality of embossed portions are disposed on the surface of the film such that an enclosed region surrounded by the plurality of embossed portions and imaginary lines that connect the plurality of embossed portions is formed, and the plurality of embossed portions are disposed at four areas on the surface of the film to form the enclosed region with rectangular shape, when an object is packaged by the film molded article, the plurality of embossed portions and imaginary lines forming the enclosed region are freely folded according to a shape or a size of the object to be packaged, and become a concave accommodating portion for accommodating the object to be packaged, wherein an object to be packaged is disposed in the enclosed region formed on the film molded article, the pair of film molded articles are superimposed to cover the object to be packaged, and the object to be packaged is a lithium ion secondary battery cell.

2 . The film packaged body according to claim 1 ,
wherein the embossed portion has a semicircular shape, a triangular shape, a linear shape, a polygonal line shape, a curvilinear shape, a rectangular shape, a circular shape, or a point shape in plan view.

3 . (canceled)

4 . The film packaged body according to claim 1 ,
wherein the embossed portion has a shape that changes in multiple stages in a thickness direction from the surface of the film.

5 . (canceled)

6 . The film packaged body according to claim 1 ,
wherein the film is made of a heat-sealable laminate material.

7 . A film packaged body according to claim 1 ,
wherein a peripheral portions of the film molded articles are sealed.

8 . (canceled)

9 . A method of manufacturing a film packaged body by superimposing pair of film molded articles, comprising
on the surface of the film to forming a concave or convex embossed portion to product the film molded articles., causing plastic deformation in the film by adding a shape to at least a part of the surface of the film using a mold, forming a plurality of the embossed portions to be disposed apart from each other on the surface of the film, the plurality of embossed portions is forming to four areas on the surface of the film to form the enclosed region with rectangular shape, securing formation of an enclosed region surrounded by the plurality of embossed portions and imaginary lines that connect the plurality of embossed portions is formed, when an object is packaged by the film molded article, the plurality of embossed portions and imaginary lines forming the enclosed region are freely folded according to a shape or a size of the object to be packaged, and the enclosed region become a concave accommodating portion for accommodating the object to be packaged, disposing an object to be packaged in the enclosed region formed in one film molded article between the pair of film molded articles, subsequently, superimposing the other film molded article on the one film molded article while the object to be packaged is covered in the enclosed region formed in the other film molded article, and wherein a lithium ion secondary battery cell is used as the object to be packaged.

10 . The method of manufacturing a film packaged body according to claim 9 ,
wherein the mold includes a punch and a die, and a tip portion in contact with the surface of the film in the punch is formed in a semicircular shape, or a triangular shape in plan view, and wherein a shape is added to the surface of the film using the mold, and thus a plurality of the embossed portions having a semicircular shape, or a triangular shape in plan view are formed on the surface of the film.

11 . (canceled)

12 . A method of manufacturing a film packaged body according to claim 1 , comprising
sealing peripheral portions of the pair of film molded articles after the pair of film molded articles are superimposed.

13 . (canceled)

14 . A film packaged body obtained by the method according to claim 9 .

15 . The film packaged body according to claim 1 ,
wherein the film is a laminate film of a metal material and a resin.

16 . The film packaged body according to claim 15 ,
wherein the metal material comprises at least one selected from the group consisting of aluminum, stainless steel, and brass.

17 . The film packaged body according to claim 15 ,
wherein the film is a laminate film of an aluminum and a nylon resin.
