Field of the Invention The present invention relates to a container pouring member provided with a barrier resin intermediate layer integrated with a container such as a pouch, and more particularly, to a barrier resin intermediate layer substantially lacking. The present invention relates to a container pouring member which is provided continuously without any, and the exposure of the barrier resin intermediate layer on the end side of the container pouring member is reliably prevented.

For example, using the moisture resistance and hygienic properties of the polyolefin resin as inner and outer layers,
On the other hand, in order to compensate for the inferior oxygen barrier property of the polyolefin resin, a container in which a barrier resin such as an ethylene-vinyl alcohol copolymer is used as an intermediate layer and these are laminated is widely used. In this case, the polyolefin layers provided on both sides of the ethylene-vinyl alcohol copolymer layer also have a complementary action of preventing a decrease in the barrier properties of the ethylene-vinyl alcohol copolymer due to humidity.

と容器との密着が不十分となるといった問題がある。By providing a barrier resin layer also on the container pouring member, volatilization of flavor components outside the container is prevented, and permeation of oxygen into the container is suppressed. Therefore, the preservability of the contents is improved. However, in the case of a conventional multi-layer container pouring member having a barrier resin as an intermediate layer, the intermediate layer made of the barrier resin tends to be exposed at the upper end and / or lower end thereof. There is a problem that the barrier property is reduced due to moisture absorption of the conductive resin, the barrier resin layer is peeled off, or the adhesion between the pouring member and the container is insufficient.

An object of the present invention is to provide a container pouring member in which the end of the container pouring member is surely prevented from being exposed.

するといった問題がある。As already pointed out, when a plastic container pouring member is joined to a container such as a pouch, the presence of an intermediate layer made of a barrier resin also in this pouring member requires the preservation of the contents. In the formation of the container multi-layer pouring member, for example, a cylindrical parison or sleeve obtained by extruding a resin and cutting to a certain size is used. There is a problem that the barrier resin intermediate layer is exposed at the portion (cut edge).

る。According to the present invention, even when the above-mentioned parison or sleeve for a multilayer pouring member is used, a folded portion is provided at the end of the barrier resin intermediate layer when forming the pouring member for a container. The problem can be effectively solved. That is, when the folded portion is provided at the end of the barrier resin intermediate layer, the barrier resin is not exposed by the inner layer resin or the outer layer resin on the outer periphery of the folded portion, and the cut edge of the barrier resin intermediate layer is also reduced. It is effectively sealed between the inner and outer layer resins in a folded state.

を防止する点で好ましい。In the present invention, the above-mentioned effect can be further obtained by providing a folded portion in the barrier resin intermediate layer on the upper end side and the lower end side of the container pouring member. Further, in the present invention, by providing the barrier resin intermediate layer of the sealing portion of the pouring member continuously without substantially dropping toward the tip of the sealing portion, heat can be applied to a container such as a pouch. The gas barrier property of the pouch with the pouring member integrally joined by means such as sealing and bonding can be easily obtained. In the present invention, it is preferable to provide the barrier resin intermediate layer closer to the outer resin layer in view of gas barrier properties and prevention of deterioration of contents such as flavor.

性に優れた注出部材付き容器とすることができる。According to the present invention, by providing a folded portion at the end of the barrier resin intermediate layer of the container spouting member, the inner layer resin or the outer layer resin on the outer periphery of the folded portion allows the barrier resin to be removed. Exposure can be avoided,
The cut edge of the barrier resin intermediate layer is also effectively sealed between the inner and outer layer resins in a folded state, whereby a container pouring member having excellent barrier properties can be obtained. In addition, a container such as a pouch having a container discharging member excellent in the barrier property can be easily obtained, and the container such as the pouch is formed of a multilayer packaging material using a barrier resin as an intermediate layer. Thereby, it is possible to obtain a container with a pouring member having excellent gas barrier properties as a whole.
