JP6165421B2 - Spout and packaging container with spout - Google Patents

Description

  The present invention relates to a spout attached to an opening of a packaging container that contains contents such as beverages, foods, chemicals, pharmaceuticals, detergents, and cosmetics. Moreover, this invention relates to the packaging container with a spout provided with the said spout.

  For example, as this type of spout, a hollow cylindrical tube portion with a cap attached to the upper portion, a plurality of flanges formed vertically on the lower portion of the tube portion, and a lower portion of the flange. A spout comprising a pouch and a fusion part fixed by heat fusion is provided (see, for example, Patent Document 1 below).

  In the content filling device in the process of filling the packaging container with spout, the mounting device in the process of mounting the cap on the spout, etc., the intermediate shaft formed between the upper and lower flanges is clamped by the clamping member of the device. Thus, the packaging container is held.

  The holding member is often unique depending on the device, and when the spout is incompatible with the holding member, the holding member cannot fit into the intermediate shaft portion, or the holding member cannot sufficiently hold the spout, and the packaging container May fall off. For this reason, a plurality of spouts suitable for each clamping member are used properly or replaced with clamping members suitable for the spout.

  In addition, a spout is provided in which three or more flanges are provided on the upper and lower sides of the spout in the axial direction so that the distance between the flanges can be changed to cope with a plurality of clamping members (for example, see Patent Document 2). However, since the length of the spout in the axial direction becomes longer, the manufacturing cost becomes higher due to the complexity and size of the structure. Spouts are often used in packaging containers to contain consumables such as beverages, foods, chemicals, pharmaceuticals, detergents, and cosmetics. It can never be ignored.
