Description

  The present invention relates to a refilling pouch with a spout that is used as a packaging material for storing seasonings for refilling, cosmetics, detergents, and the like, and that can be easily refilled into a main body container.

Conventionally, for the purpose of environmental conservation and resource saving, refill pouches for storing the refill contents have been widely used in order to repeatedly use the empty main container. As this refilling pouch, a rectangular pouch in which the peripheral portions of the front and back synthetic resin films were sealed by heat fusion or the like was used, but this refilling pouch transfers contents to the main body container. Occasionally, the contents of the pouch are cut off between the upper ends or the corner of one side of the pouch is cut to transfer the contents to the main body container. It was. For this reason, in order to facilitate the transfer work of the contents, a spout portion with a predetermined width corresponding to the diameter of the main body container is formed at the pouring position of the upper corner of the pouch, which greatly affects the pouring amount. In order to secure the opening area of the spout portion, a small tube that is a member different from the film is inserted into the spout portion (for example, see Patent Document 1), or the film itself near the spout is inflated to form a three-dimensional shape. Many proposals have been made to secure an opening area.

  However, in the pouch in which the small tube is inserted into the spout portion, the small tube is inserted into the flow passage of the spout portion, so that the opening area of the flow passage is reduced by the thickness of the small tube, and the diameter of the main body container is small. However, it was difficult to pour the contents, it was difficult to replace the air inside the pouch, the contents to be poured pulsated, and the contents were liable to stagnate between the small tube and the film. In addition, the pouch that has a three-dimensional shape by inflating the film itself in the vicinity of the spout, when the contents are poured out from the opened spout, the vicinity of the base of the spout is swollen by the pressure of the contents, The front and back films are pulled to both ends of the spout portion, and are in a pseudo close contact state, and the opening is blocked without swelling to the tip of the spout portion, and the contents may not be poured out. In addition, seal portions are formed on the upper side and the lower side of the opening portions, and the opening portions are greatly affected by these seal portions, and a suitable opening shape may not be obtained.

  The present invention solves the above-mentioned problems of the conventional refilling pouch, the opening of the spout portion at the time of opening is easy, the state in which the contents are poured out is stable, and the spout portion The present invention provides a refillable pouch with a spout that can have a relatively large opening width.

  That is, the first invention of the present invention is a rectangular pouch in which a front side film and a back side film are overlapped to form a seal part on the outer periphery of the four sides, and at the upper one side corner of the trunk part of the pouch, A spout part composed of a front seal part, an upper seal part, and a lower seal part is formed, and when the pouch is opened, a rear position of the front seal part of the spout part is cut and opened. The opening cross-sectional shape of the spout port is a point-symmetric shape from the opening center point, and the upper seal portion and the lower seal portion of the opening cross-sectional shape of the spout port portion are point-symmetric from the opening center point. In the predetermined position below the upper seal part of the film on either the front or back side of the pouring path of the pouring port part, a linear shape-retaining embossing projecting outward is performed, and the film on the other side To the outside at a predetermined position above the lower seal We were subjected to linear embossing shape retaining made as a note refill pouch with an outlet, characterized in.

  Next, according to a second aspect of the present invention, a linear shape-retaining embossing projecting outwardly on the pouring path of the spout portion is extended from the spout portion toward the center of the body of the pouch. A pouch for refilling with a spout according to the first invention, characterized in that it is provided.

  Next, the third invention of the present invention is characterized in that the upper seal portion and the lower seal portion of the spout portion are brazed so as to induce twisting by alternately pressing the ruler. A pouch for refilling with a spout according to the first or second aspect of the invention.

  According to a fourth aspect of the present invention, there is provided a pouch for refilling with a spout according to any one of the first to third aspects, wherein the pouch is a self-standing pouch provided with a fold in the bottom. It is.

  The refilling pouch with a spout of the present invention has a linear shape-retaining embossing projecting outward at a predetermined position below the upper seal portion of the film on either side of the spout path of the spout portion. Since the embossing for linear shape retention that protrudes outward is applied to a predetermined position above the lower seal portion of the film on the other side, the contents are poured out by opening and tilting. Sometimes, the contents stored in the pouch body portion easily flow into the pouring path of the spout portion, and the opening of the spout portion is easy. Furthermore, a linear shape-retaining embossing projecting outwardly from the spout path of the spout portion extends from the spout portion toward the center of the pouch body, and above the spout portion. For the side seal part and the lower seal part, the brazed parts that are creased in a staggered manner to induce twisting make it easy for the contents to flow into the spout passage of the spout section, and further facilitate the opening of the spout section It is.

  Further, as described above, the refilling pouch with a spout of the present invention has a suitable shape of the pour-out path because the contents stored in the pouch body easily flow into the pour-out path of the spout section. It is obtained and the state of the content being poured out is stable.

  In addition, since the refillable pouch with the spout of the present invention forms a spout portion with the front seal portion, the upper seal portion, and the lower seal portion at the upper one side corner of the trunk portion of the pouch, It is possible to make the dimension of the opening width of the spout portion relatively large.
