  In the conventional container of this type, the presence of the hole in the straw portion enables the suction of the stored items stably and the efficient suction with a small remaining amount. However, the straw portion needs shape retention in order to achieve such a purpose, and as a result, the hole and the lower end opening are located at substantially fixed positions in the container body, so the container body is made of a flexible material. Despite being formed, there is still room for improvement in its suction efficiency.

  The present invention has been made in view of the above points, and can more efficiently suck the stored items, and can be easily handled, and has a simple structure and can be manufactured at low cost. Propose a container spout.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows an example of a container using the spout of the present invention, and the container includes a container body A and a spout B.

  The container A can preferably be a flexible bag-like shape, for example, a type in which the periphery of two sheets is fixed by means such as fusion, a box-type so-called gusset type, or a horizontal triangular prism shape The so-called standing pouch type can be employed, and various flexible containers such as a thin-walled blow molded container can be used. For such a container body, various materials having flexibility such as a single layer or a laminate of a synthetic resin or a laminate of a synthetic resin and a metal thin film layer can be selected. In the case of the bag-shaped container body A, the spout body 10 is fused and fixed to the mouth portion 2 thereof. The mouth 2 of the container body A is mainly located at the upper end, but is not limited thereto.

  The spout B includes a spout body 10 and a derivative 11. Both are integrally formed of synthetic resin. The spout body 10 has a cylindrical shape in which the outer periphery is welded and fixed to the mouth portion 2 of the container body A, and in order to enable close welding of the mouth portion 2 to the lower portion of the outer circumference, A landing outer surface a is formed to protrude. In addition, a pair of flanges 12 is provided above the fusion outer surface a, and further, a protrusion 13 and a screw 14 are sequentially provided on the upper outer periphery thereof. Further, a cap 15 is screwed onto the spout body 10, and a screw 16 that is screwed into the screw 14 is provided around the inner periphery. In addition, a cut band 18 that can be cut out through the fracture portion 17 is formed integrally with the lower end surface of the cap 15 so that the unused state can be expressed. The cut band 18 has a plurality of engagement pieces 19 projecting obliquely upward from the inner surface, and the front ends of the engagement pieces 19 are engaged with the lower surface of the protrusion 13 respectively. Then, when the cap 15 is forcibly rotated in the screwing direction, the breaking portion 17 is broken and the cut band 18 is separated, so that the cap 15 can be screwed and the opening is confirmed. The fusion outer surface a is not limited to this shape, and may be, for example, a belt-like fusion surface having an elliptical shape in plan view or both side surfaces of a pair of left and right plate-like protrusions.

  The derivative 11 acts to suck the contents in the container body A smoothly and efficiently, and also contributes to the shape retention of the container body A having flexibility. In the present invention, a semi-tubular shape in which the central portion of the upper edge arranged at the peripheral edge of the lower end opening 20 of the spout body 10 is connected to the spout body 10 via a hinge 21a is formed. In addition, a pair of expansion plate portions 22 that can be expanded via hinges 21b are defined on both sides. Specifically, a vertically long rectangular substrate 23 whose upper edge is connected to a predetermined position on the lower surface of the spout body 10 via the hinge 21a, and one side edge is connected to both sides of the substrate 23 via hinges 21b. And a pair of the spread plate portions 22 each having a predetermined angle with respect to the substrate 23. The angle formed is set to a predetermined angle such that the spout body 10 is positioned at the periphery of the lower end opening of the spout body 10, and this angle has a certain degree of freedom. In the illustrated example, it extends symmetrically from the substrate 23 located at the rear of the opening 20, and the angle formed with each substrate 23 is about 120 °.

  Further, a releasable expansion preventing means for preventing the expansion of each expansion plate portion 22 is provided. In the example of FIG. 1, as the expansion preventing means, the upper surface of each expansion plate portion 22 is connected to the lower surface of the spout body 10 via an easily cut connection portion b.

The window hole 25 has a lateral width that crosses the substrate 23 and reaches both the left and right expanded plate portions 22, and is formed in the central portion in the vertical direction. The shape of the window hole 25 is not limited to this, and a plurality of the window holes 25 may be provided.

  When the container 1 configured as described above is used, for example, the cap 15 is removed, and the contents stored in the container body A are sucked from the upper end opening of the spout body 10. When the amount of stored items is reduced, the connecting portion b is cut from the top of the container body A, both the expanding plate portions 22 are opened and flattened, and then the remaining liquid is sucked in while squeezing the container body A. 5 and 6 are explanatory views for explaining the cutting of the connecting portion b. However, as shown in FIG. 5 (a), since the derivative 11 is swung by the hinge 21a, the connecting portion b becomes easier to cut. .

  FIGS. 7 to 11 show examples using other derivatives 11 in the example of FIG. The derivative 11 includes an upper substrate 23a whose upper edge is connected to the spout body 10 via a hinge 21a, a lower substrate 23b disposed below and spaced from the upper substrate 23a, both sides of the upper substrate 23a and the lower substrate. A pair of widened plate portions 22a each having a predetermined angle with respect to each of the upper substrate 23a and the lower substrate 23b are connected to both sides of the upper substrate 23a and lower portion of the one side edge via hinges 21b. ing.

  In addition, each of the expanded plate portions 22a projects inwardly from one of the expanded plate portions 22a in parallel with the upper substrate 23a and the lower substrate 23b, and is provided with a locking plate portion 26 connected to the upper substrate 23a. An engaging plate portion 27 protrudes inwardly from the other expanded plate portion 22a so as to be brought into contact with and locked to the locking plate portion 26 when the other expanded plate portion 22a is expanded and forcibly overridden. ing. Further, the locking plate portion 26 connected to the lower substrate 23b is protruded inward from the other expansion plate portion 22a, and the engagement plate portion 27 is protruded inward from the one expansion plate portion 22a. Yes.

  When using a container having such a derivative 11, for example, the cap 15 is removed in the same manner as described above, and the contents in the container body A are sucked from the upper end opening of the spout body 10. When the amount of storage becomes small, each expansion plate part 22a is forcibly opened from the top of the container body A, each engagement plate part 27 is forcibly moved over each locking plate part 26, and both expansion plate parts After opening 22a to make it flat, the remaining liquid is sucked while squeezing the container body A in the same manner.

  In each of the above examples, the substrate 23 or the upper substrate 23a and the lower substrate 23b are present in the central portion of the derivative 11. However, both expanded plate portions are provided in a V shape in the absence of the substrate. The present invention also includes forms. In addition, an example of a bag-like container body is described as the container body A, and an example in which the outer periphery of the spout body is welded and fixed to the mouth of the container body is shown, but when the container body is a blow molded container or the like, It is also possible to employ means for tightly fitting and fixing the spout body to the mouth.
