Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a hermetically sealed transparent case made of a thin synthetic resin film capable of completely blocking invasion of air and moisture.

[0002]

[Prior art]

 To describe the conventional example as a dry flower case using silica gel as a desiccant, fresh flowers are placed in a sealed case made of silica gel or polyethylene or polypropylene to remove water, and then removed and immediately removed. Dried flowers in glass containers, which are placed in a glass container together with silica gel and the opening is bonded with a glass plate lid to prevent intrusion of air and moisture in the atmosphere, have the same flower color and flower shape as fresh flowers, so they are popular. However, this type of dried flower had disadvantages such as expensive glass containers, heavy and fragile glass containers, and difficult and dangerous wall hanging.

[Means for Solving the Problems]

 In order to achieve the above object, the sealed transparent case made of a thin synthetic resin film of the present invention, as shown in the figure, includes a transparent tube made of a thin synthetic resin film that can be folded and a U-shaped or V-shaped cross section on the outside. A groove is formed to allow the cylindrical end to be fitted therein, and a lid and a wall hanging plate are provided for allowing a liquid or paste-like adhesive to flow into the groove, and the wall hanging plate is provided to allow the liquid to flow into the groove. The end of the cylinder and the lid groove can be sealed with an adhesive. In addition, in order to achieve the above object, the sealed transparent case made of a thin synthetic resin film of the present invention has a transparent tube made of a thin synthetic resin film and a U-shaped or V-shaped groove on the outside as shown in the figure. And a liquid or paste-like adhesive that can flow into the groove so that the outer surface of the groove can cover the flow of the adhesive. It is provided with a colored member and a wall hanging plate, so that the cylinder end and the lid groove can be sealed by the adhesive flowing into the groove.

In the present invention, any known thin synthetic resin film (hereinafter simply referred to as “film”) can be used, but polyethylene terephthalate is preferred in terms of transparency, hardness, moisture resistance, gas permeability and the like. Film (hereinafter abbreviated as PET film) is preferred. The film preferably has a thickness of about 75 to 350 microns in order to form a cylindrical body. Further, in order to form the film in which the cylindrical body is formed to be foldable into a rectangular cylindrical shape (illustrated as a square cylindrical shape), as shown in the explanatory view of the cross-sectional structure of the cylinder 10 in FIG. Four half-cut lines 13 are formed on the film, three-sided plates 11, 11, 11 and connecting pieces 111, 111 are provided, and both ends of the one-sided plate 12 of another film are bonded or fused to the connecting pieces 111, 111. As shown in the cross-sectional view of the cylinder 10C in FIG. 5, the film is provided with four half-cut lines 13C, and four face plates 11C, 11C, 11C, 11C and connection pieces 111C are provided. One end of the one face plate 11C is bonded or fused. As shown in the explanatory view of the cross-sectional structure of the cylinder 10D in FIG. 6, a film 13D that can be bent at each end of four identical films 11D, 11D, 11D, and 11D. Do not glue or fuse them together There is. Further, as shown in the explanatory view of the cross-sectional structure of the cylinder 10E in FIG. 7, the film forming the cylindrical body is formed by bending both ends of one film 11E into a cylindrical shape at the time of use and superimposing and bonding or fusing. However, in order to form the cylindrical body so as to be easily foldable, both ends of the two films 11B, 11B can be bent as shown in the explanatory view of the sectional structure of the cylinder 10B in FIG. For example, the film 12B is bonded or fused and connected. The lid is desirably made of a synthetic resin or a synthetic resin film, and the lid groove can be fixed to the fitted cylinder end and sealed when the adhesive is poured and solidified. In addition, the lid groove is preferably one in which at least the outer surface of the groove is colored so that solidification of the adhesive can be concealed from the outside. For mass production, the entire lid is preferably transparently colored or opaque. As the liquid or paste adhesive (hereinafter simply referred to as adhesive), all known adhesives can be used, but those having high transparency or some elasticity after solidification are desirable. The wall hanging plate is preferably a film similar to the film forming the cylindrical body.

First Embodiment of the Invention A first embodiment of the present invention is shown in FIGS. 1, 2 and 4. FIG. The sealed transparent case made of a thin synthetic resin film according to the present embodiment includes a cylinder 10, a pair of lids 20, 20 and a wall hanging plate 30. The tube 10 is a collapsible square tube, a colorless and transparent PET film having a thickness of 188 microns, and a pair of three-sided plates 11, 11, 11 by four half-cut curves 13 as shown in FIG. Are provided, and a one-face plate 12 bonded or fused to the connection pieces 111, 111 at both ends is provided. The lid 20 is formed of a colorless and transparent PET film having a thickness of 350 microns, and as shown in FIG. 2, the end of the cylinder 10 is fitted on the outside and the U-shaped or V-shaped so that the adhesive can flow therein. The groove 21 is formed. The wall-mounting plate 30 is a PET film having a thickness of 188 microns and has a wall-mounting hole 31 formed therein. Accordingly, after an adhesive (in this example, a vinyl acetate resin emulsion paste adhesive) (not shown) is allowed to flow into the groove 21 of the lid 20, one end of one cylinder 10 is immersed in the adhesive. When the adhesive is dried and solidified in the groove 21, the end of one cylinder 10 and the lid groove 21 are fixed and sealed. Next, a hollow molded body 40 such as a paper vase, a cloth vase, or a synthetic resin clay vase in which the other lid 20 is filled with a required sealed article (in this example, silica gel (not shown)) is formed. The dried silica gel flower 50) inserted into the molded body 40 is placed and fixed with an adhesive or the like. After the adhesive flows into the lid groove 21 of the other lid 20, the cylinder 10 is inverted and the other end of the cylinder 10 is inverted. When the sides are fitted and the adhesive is dried and solidified, a sealed case is created in which the entire case completely blocks air and moisture in the air. Next, if the wall hanging plate 30 is bonded to the cylinder 10, the wall can be hung by the holes 31. In this embodiment, one of the four PET films 11, 11, 11 and 12 forming the cylinder 10 is a colored film or a patterned film. For example, when the sealed object is a doll, a golden film is used as the film 12. If it is used as a background plate, the beauty of the sealed case may be further improved.

[0007]

Second Embodiment of the Invention A second embodiment of the present invention is shown in FIGS. 3 and 8. The sealed transparent case made of a thin synthetic resin film of this embodiment includes a cylinder 10B, a pair of lids 20B, 20B, and a wall hanging plate 30B. The cylinder 10B can be formed into a substantially cylindrical shape so as to be foldable. As shown in FIG. 8, both ends of two 75 μm-thick transparent and colorless PET films 11B are bent to a 38 μm-thick transparent transparent film. It is a colorless PET film 12B bonded and fused. The lid 20B is formed of a 250-μm-thick white opaque PET film, into which the end of the cylinder 10B is fitted on the outside and into which a U-shaped to V-shaped groove (not shown) through which an adhesive can flow. ) Is formed. The wall hanging plate 30B is a PET film having a thickness of 75 microns, and has a wall hanging hole 31B. Other configurations and operations are the same as those of the first embodiment of the present invention, and therefore, detailed description is omitted.
