Problems solved by technology

However, there is a problem that, with this method, the shrink film needs to be longer than the originally required length, which is wasteful, and it is necessary to set the heating of the part where winding or sealing is performed on the inner side, respectively. condition, wrinkling during shrinkage resulting in poor appearance

no. 1 approach

[0051] Hereinafter, the first embodiment of the present invention will be described in detail with reference to the drawings. In addition, this invention is not limited to the following embodiment, and is interpreted.

[0052] figure 1 It is a perspective view showing the cylindrical container of this embodiment. figure 2 It is a longitudinal sectional view of the cylindrical container of this embodiment. In addition, image 3 It is a partial cross-sectional plan view of the cylindrical container of the present embodiment viewed from above, Figure 4 It is a schematic cross-sectional view showing an example of the laminated material constituting the main body of the cylindrical container. In the present embodiment, the plan view refers to a view viewed from the direction of the central axis O of the main body, which will be described later.

[0053] Such as figure 1 As shown, the cylindrical container 1 has: a cylindrical container main body 2 having a cylindrical main body por...

no. 2 approach

[0089] Next, the second embodiment of the present invention will be described. The second embodiment of the present invention does not use the hot-melt adhesive 21 and holds the main body portion 16 and the cylindrical shrink film 13. In addition, this invention is not limited to the following embodiment, and is interpreted.

[0090] The cylindrical container according to this embodiment is different from the first embodiment in that the main body portion 16 and the cylindrical shrink film 13 are not bonded with the hot-melt adhesive 21. Also used in the second embodiment Figure 1 to Figure 4 The structure shown. Regarding the same structure as that of the first embodiment, the description thereof will be omitted.

[0091] As the material of the cylindrical shrink film 13 and the second resin layer 35 of this embodiment, the same materials as those of the first embodiment can be used.

[0092] In this embodiment, the shrinkage temperature of the cylindrical shrink film 13 is high...

Embodiment

[0100] The following shows an example using the method of manufacturing the cylindrical container according to the second embodiment.

[0101]

[0102] The basis weight is 200g / m 2 On the surface of the paper, low-density polyethylene resin (LDPE) was extruded and laminated to a thickness of 50 μm to form the second resin layer. Next, the gas barrier film (barrier layer) in which aluminum oxide is vapor-deposited on a 12μm thick polyethylene terephthalate resin (PET) film and the back of the paper are extruded with LDPE (third resin layer) 45μm After lamination, the LDPE was extrusion-laminated with a thickness of 60 μm as the first resin layer on the opposite side of the paper of the gas barrier film to form a laminate. This laminated body forms a cylindrical container body of Φ48 mm. As the shrink film, use OPS film DXL-270-41S 45μ (trademark registration, made by "Mitsubishi Resin") flexible printed matter, as a solvent for film bonding, use a mixture of ethyl acetate and cyc...

Abstract

This cylindrical container is provided with: a cylindrical container main body having a cylindrical body part; and a cylindrical shrink film tightly covering the outer circumferential surface of the body part, wherein the body part and the cylindrical shrink film are adhered by a hot melt adhesive at one portion of at least an end edge part of the body part.

Description

Technical field [0001] The present invention relates to a cylindrical container in which the main body of the container is covered with a shrink film, and relates to a cylindrical container in which the covered shrink film is less likely to deviate from the main body and a method of manufacturing the same. [0002] This application claims priority based on Japanese Patent Application No. 2016-252576 for which it applied to Japan on December 27, 2016, and uses the content here. Background technique [0003] Currently, product names and other information are recorded in the main body of metal, plastic, glass and other cylindrical containers that contain liquid contents such as fruit juices and soft drinks, and various designs and designs are implemented. , The protection of the contents and paste the label. In addition, in recent years, attention has been paid to paper as a renewable resource due to increased awareness of eco-environmental protection, and cylindrical containers with...
