と接触する。The tube container body formed of the above-mentioned laminated sheet has the other side portion superposed on the one side portion of the laminated sheet, and the surface resin layer of the one side portion and the other side portion. In the back sticking part, which is the container body sticking part formed by welding the back surface resin layer of the side part, the end surface of the side side part of the laminated sheet located on the inner surface side of the container comes into contact with the inner filling in the tube container.

を低下させる等の弊害が発生する。For this reason, when, for example, an aluminum foil or an ethylene-vinyl alcohol copolymer resin layer as a gas barrier layer is laminated in the laminated sheet, these layers come into contact with the internal filler. However, the quality of the filling material may be deteriorated, or the gas barrier of the laminated sheet may be deteriorated.

容器内の内填物中に溶出し、内填物の風味を損なう。That is, when aluminum foil is laminated in the laminated sheet forming the tube container body, when the acid or alkaline substance is filled in the tube container body, the inner surface side of the container body The aluminum exposed on the end faces of the side edges of the laminated sheet located at is eluted into the inner filling in the tube container, and the flavor of the inner filling is impaired.

が損なわれる。When the ethylene-vinyl alcohol copolymer resin layer is laminated in the laminated sheet forming the body of the tube container, the side edges of the laminated sheet located on the inner surface side of the container body The ethylene-vinyl alcohol copolymer resin layer exposed on the end surface of the portion absorbs moisture in the body of the tube container, impairing the gas barrier function of the laminated sheet.

樹脂で完全には被覆し得ない場合がしばしば発生する。Therefore, as shown in [FIG. 4], the heat-sealing resin layer H, which becomes the inner peripheral surface layer of the tubular molded body when forming the body-bonding portion of the tubular molded body with the laminated sheet. The end face of the laminated sheet is coated with the resin forming the heat-sealing resin layer H by the flow of No. 1, but in particular, a resin having a high melting temperature and low fluidity at the time of heat melting, for example, a gas. When a nitrile resin described in JP-B-57-60234 is used as a heat-sealing resin layer having excellent barrier properties as a heat-sealing resin layer, the end surface of the laminated sheet is treated with the heat-sealing resin. It often happens that it cannot be completely covered.

際のエンドシール部の形成が不安定になる。In addition, a back adhesive portion formed by stacking the other side portion on one side portion of the laminated sheet and fusing the front surface resin layer of the one side portion and the back surface resin layer of the other side portion to each other is welded. The cylindrical molded body has a thick back-adhering portion, and a step is formed in the portion. Therefore, the formation of the end seal portion when obtaining the sealed tube container becomes unstable.

Also, the back surface of the tube container body does not expose the end surface of the laminated sheet forming the tube container body to the inside of the tube container, and has excellent properties for quality retention of the filling material. A tube container body having the same is provided.
