Description

  The present invention relates to a spout for a pouch container to be attached to an opening of a pouch container made of synthetic resin or the like formed in a bag shape filled with a liquid material such as juice, soup, seasoning, and detergent, and a pouch container provided with the same About.

Conventionally, a synthetic resin container in which a pouch container formed in a bag shape with a flexible synthetic resin sheet or the like is filled with a liquid material and a spout for a pouch container serving as a spout is attached to the opening of the pouch container is known. ing. Such a spout for a pouch container is generally integrally formed of synthetic resin or the like, and is disposed between the opened synthetic resin sheets and fixed by heating and welding them.
In connection with the improved convenience at the time of opening the spout for such a pouch container, for example, Patent Document 1 discloses a flexible synthetic resin outer cylinder and inner cylinder inside a synthetic resin bag body. A bag spout is formed in which the lower ends of the two cylinders are integrally connected, a lid is provided at the tip of the inner cylinder, and the both cylinders are formed so as to protrude and retract outside the bag body. Yes.

Further, Patent Document 2 discloses a welding fixing portion extending in a direction orthogonal to the axial direction of the dispensing cylinder, and a welding extending in the longitudinal direction of the welding fixing portion and continuing to the side end of the welding fixing portion. The spout is provided with a thin-walled portion, and the upper end of the welded thin-walled portion is separated downward from the bag upper end fixing position of the welded fixed portion by a resin pool interval.
In Patent Document 3, rectangular vertical cores in the diameter direction and the center line direction are provided symmetrically on both outer sides of the base of the spout cylindrical spout, and the upper and lower ends of the left and right rectangular vertical cores and the middle thereof are spaced apart from each other. A plurality of recumbent ribs are provided symmetrically in the front-rear and left-right directions, and the recumbent is inclined from the front and rear outer peripheral parts of the cylindrical spout toward the base end of the left and right vertical reeds in a generally rhombus shape, Describes a synthetic resin spout bag in which an air reservoir space having a vertical core and a cylindrical spout outer periphery as a bottom surface is provided.

  However, in the conventional spout, the cap gripping ability when opening the cap covering the spout outlet of the spout is poor, and once opened, it is easy to handle the lid part in re-sealing and ensure hygiene around the opening. There was a problem that it was difficult. In particular, in the spout provided in the bag body of Patent Document 1 so as to be freely retractable, it is not easy to pull out the lid immersed in the bag body. In addition, there is a problem in that when the spout container is displayed at a storefront or the like, dust or the like adheres to the portion around the lid and is unsanitary.

Further, in the spout described in Patent Documents 2 and 3, since the pouring portion is formed to protrude from the welded portion, the spout not only becomes an obstacle during the distribution of the pouch, but the lid portion and the pouring portion are integrated. In the case of the one-piece type formed in the above, there is a possibility that an accident that breaks at the time of distribution may occur because the bent portion protrudes.
Moreover, in order to maintain the pouring part hygienically, it was necessary to provide a cover and the like separately. In this case, by covering the spout with the pouch itself, a barrier pouch can be made by controlling the amount of oxygen at the time of sealing and sealing the spout, but there was a problem when removing the cover because the spout part protrudes outside .

  The present invention has been made to solve the above-described conventional problems, and provides a spout for a pouch container excellent in unsealing property and handling property at the time of opening, as well as hygiene and safety at the time of distribution.
