Description

  The present invention relates to thin containers such as detergents, foods and seasonings, and particularly to refilling containers such as these seasonings.

Conventionally, as this type of container, a part of the periphery of a flexible bag-like container body formed by overlapping two sheets protrudes outwardly to form a hollow protrusion, and a spout is formed by cutting the tip of the protrusion. What is opened is known (Patent Document 1), and in order to facilitate liquid pouring, a liquid passage securing rod-shaped material is inserted into a short tubular hollow protrusion. (Patent Document 2, Patent Document 3).
JP 2002-337893 JP 09-024956 A JP-A-11-152153

Since the thin containers for refilling in both patent documents protrude from the bag-like container body to the side outward and the hollow protrusion is short, the container is unexpectedly opened before the liquid is discharged after opening the spout at the tip of the protrusion. There is a risk of spilling the liquid from the spout if the body is gripped strongly. In order to avoid such inconvenience, it is conceivable to increase the protrusion length of the hollow protrusion from the container body containing the content liquid. If only the hollow protrusion is protruded, the hollow protrusion will fluctuate, making the dispensing operation difficult, and inconvenient during transportation and storage.

    The present invention allows a rod-like material with a fluid passage to slide into a hollow protrusion that is bent and protrudes from a container body so that refilling of liquid can be performed reliably and easily without spilling around. An object is to provide a thin container fitted.

The first means is that a hollow and protruding part of a thin and flexible container part protrudes outwardly, and a spout can be opened at the tip of the protruding part, and a rod-like material with a fluid passage is inserted into the hollow protruding part. In the thin container, the rod-shaped member 30 is slidably provided in the hollow protrusion 6 that is bent from the side edge of the container body 12 and extends along the side edge, and the hollow protrusion 30 is inclined to the side outward. At this time, the rod-shaped member 30 is moved from the distal end side of the hollow protrusion into the bent tube portion 16 on the proximal end side so as to secure a liquid passage in the bent tube portion 16.
Specifically, the container portion can be formed by overlapping two synthetic resin films having the same shape and welding the edges. In addition, the container body is usually flat and has a side edge (including an upper side edge and a lower side edge in addition to the left and right side edges) linearly formed, The hollow protrusion is an L-shape (including a key shape) formed by projecting a straight pipe portion along a remaining container body side edge portion through a curved pipe portion from a communication port opened at one end portion of the container body side edge. It shall be possible. Further, the pouring protrusion may be provided with a tap-shaped end portion that serves as a knob that bends further from the front end side of the straight pipe portion toward the opposite side of the container body.

    Of the “moving rod-shaped member 30 from the tip end of the hollow projection” in the first means, “the tip end side of the hollow portion” means “the hollow projection portion on the tip side of the curved pipe”. Meaning.

    The second means includes the first means, and the rod-shaped member 30 is a bent pipe portion 16 of the inner surface of the hollow protrusion 6 in a state where the hollow protrusion 6 is inclined outwardly to the side. It is formed in such a length that it can contact the two points A and B located on both sides in the flow direction of the outer edge part and one point C on the inner edge part of the curved pipe so as to maintain the inclined state of the hollow protrusion 6. ing.

    The third means includes the second means, and the container part 2 superimposes two synthetic resin films having the same shape corresponding to the half bodies of the container body 12 and the hollow protrusion 6. The edge portions 4 of both films are welded, and the contact points A, B, and C with the rod-shaped material 30 are positioned at the edge portions on both sides of the hollow protrusion 6.

  The fourth means includes the first means, the second means, or the third means, and the horizontal width of the rod-shaped member 30 is inclined when the hollow projection 6 is inclined outwardly to the side. The inner diameter of the bent pipe portion 16 in the state is almost the same.

  The fifth means includes any one of the first to fourth means, and a part of the rod-shaped material 30 is welded to the inner surface of the straight pipe portion 18 on the distal end side of the hollow protrusion 6. .

  The sixth means includes any one of the first to fifth means, and the rod-shaped material 30 is a pipe having an outer diameter substantially the same as the inner diameter of the hollow protrusion 6.

  The seventh means includes any one of the first to sixth means, and connects the hollow protrusion 6 and the opposing edge portion of the container main body 12 via the breaking line 20.

The invention according to the first means has the following effects.
○ Since the rod-like material 30 with a liquid passage can be moved into the curved pipe portion 16, it is possible to prevent the passage from being blocked by refraction of the curved pipe portion 16 in a state where the hollow protrusion 6 is tilted outward. .
O Since the rod-shaped material 30 is simply inserted into the hollow protrusion 6 of the existing bag-like container, the structure is simple and the production can be inexpensive.

  According to the invention relating to the second means, the rod-shaped material 30 is brought into contact with the three points A, B, C on the inner surface of the hollow protrusion 6 in a state where the hollow protrusion 6 is inclined outwardly to the side. Since the inclined state of 6 is maintained, there is no need to support the hollow protrusion by hand until the hollow protrusion 6 is pulled out to the side and inserted into, for example, the mouth and neck of the refill container. Easy to use.

  According to the invention relating to the third means, since the edge portion 4 having a relatively high strength in the flexible container portion 2 is used as a fulcrum for supporting the rod-like member, the inclined state of the hollow protrusion 6 is more reliably achieved. Can be maintained.

  According to the fourth aspect of the invention, since the rod-shaped member 30 is configured not to drop into the container body 12 when the hollow protrusion 6 is inclined upward as shown in FIG. As described above, a comfortable dispensing operation can be performed.

  According to the invention relating to the fifth means, since a part of the rod-shaped material 30 is welded in the hollow projection 6, the rod-shaped material does not jump out unexpectedly when the tip of the hollow projection is opened.

  According to the sixth aspect of the invention, since the rod-shaped material 30 is made into a pipe, the liquid can be smoothly fed to the outside through the pipe hole.

  According to the seventh aspect of the invention, since the hollow protrusion 6 and the opposite edge portion of the container body 12 are connected via the breaking line 20, the hollow protrusion 6 is suspended from the container body 12. Can be prevented.

  1 and 2 show a thin container according to the first embodiment of the present invention. First, known parts of the container will be described.

  This thin container is composed of a bag-shaped container portion 2 and a rod-shaped material 30.

    The container part 2 is formed by superimposing two flexible synthetic resin films on the front and back sides of the same shape and welding the edges 4 of both films, and the container part 2 including a part of the edges. The portion protrudes outward to form a hollow protrusion 6. The hollow protrusion is formed by joining the two front and back film portions. Further, a break line 8 is formed on the distal end side of the hollow protrusion so that the portion 10 on the distal end side of the break line can be separated.

    The rod-shaped material 30 is inserted into the hollow protrusion 6.

    In this invention, the container part 2 has the rectangular container main body 12, and it is back via the curved pipe part 16 from the communicating port 14 opened to the upper edge front end part (left end part in the drawing) of the container main body. The straight pipe portion 18 protrudes. Further, in the illustrated example, the upper edge portion excluding the front end portion of the container body 12 and the lower edge portion of the hollow protrusion 6 are connected via a breaking line 20 so that the entire container portion 2 is shaped into a rectangle. ing. Further, a perforation 22 for facilitating the deformation of the base portion of the hollow protrusion 6 is formed at the back of the breaking line 20. In addition, although the illustrated hollow protrusion 6 is formed in a substantially L-shape that protrudes through the bent portion and protrudes from the straight pipe portion, the shape can be changed as appropriate, and the upper portion extends from the rear end portion of the straight pipe portion. A faucet-shaped end portion (not shown) that is curved to the right is provided, and the break line 20 between the container body 12 and the hollow projection 6 can be broken by picking the faucet-shaped end portion and pulling it upward. May be. In this case, it is preferable that a break line 8 is provided laterally at the upper end portion of the faucet-shaped end so that the spout can be opened.

    In the present embodiment, the rod-shaped member 30 is formed of a pipe having the same outer diameter as the inner diameter of the hollow protrusion 6, and the pipe hole is used as a liquid passage 32. However, the structure of the rod-shaped material can be changed as appropriate, and can be a non-cylindrical shape as will be described in a later-described modification. In the illustrated example, the rod-shaped member 30 is inserted into the latter half portion of the straight pipe portion 18 (the portion closer to the curved pipe), and is welded 34 to the inner surface of the latter half portion. In addition, the rod-shaped material 30 shall have the intensity | strength of the grade which can support the inclination state of the hollow protrusion 6 so that it may mention later.

    In the above configuration, in the state of FIG. 1, the long hollow protrusion 6 and the container main body 12 are connected via a broken line 20 to prevent the hollow protrusion from hanging during transportation. 1 is cut off from the state of FIG. 1 to incline the hollow protrusion 6 upward and outward as shown in FIG. 2, and the break line 8 on the distal end side of the hollow protrusion is broken to open the spout. When the rod-shaped member 30 is further moved into the bent tube portion 16, the rod-shaped member secures a flow path in the bent tube and is locked in the bent tube to maintain the inclined state of the hollow protrusion 6. The action of the rod-shaped material at this time will be described with reference to FIGS. In both figures, the left and right widths of the rod-shaped member 30 are drawn slightly smaller than the inner diameter of the hollow protrusion 6 for convenience of explanation. The straight pipe portion 18 of the hollow protrusion 6 is inclined from the horizontal state shown in FIG. 3 to the upward and outward direction shown in FIG. 4, and the rod-shaped material 30 is moved from the straight pipe portion 18 into the curved pipe portion 16. Then, the rod-shaped material comes into contact with two points A and B on both sides in the flow path direction of the outer edge portion of the curved pipe portion 16 and one point C on the inner edge portion of the curved pipe. At this time, the rod-shaped member supports the straight pipe portion 18 with the point C as a fulcrum, the point A as a force point, and the point B as a fulcrum, and supports the inclined state of the hollow container. Here, since the points A to C are all on the edge 4, the support can be made more reliable.

    FIG. 5 shows a modified example of the rod-shaped member 30 of the container of FIG. 1, and the cross-section of the rod-shaped member is a cross shape, and a recess between the vertical plate portion and the horizontal plate portion forming the cross is passed. It is formed in the liquid path 32. In addition, the shape of the rod-shaped member can be appropriately formed such as a C-shape or an L-shape in addition to the above-described cross shape.
