Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a bag with a mouthpiece that contains a liquid and is taken out by sucking the liquid from the mouthpiece side.

[0002]

[Prior Art]

 In general, since it is inexpensive to use a bag as a means for containing and selling a liquid, it is widely adopted in the distribution mechanism. In order to efficiently take out the liquid contained in such a bag, a suction tube is attached to the mouthpiece body of this bag, the liquid is sucked by this suction tube, taken out from the bag, and supplied to a predetermined location. Such a system has been developed.

In the system as described above, when the liquid in the bag is sucked and used, no problem occurs in the initial stage of use, but during use, the inside of the bag gradually becomes a vacuum, and a part of both sides of the bag Come into close contact with each other. Such close contact occurs particularly near the mouthpiece, so that the subsequent suction reduces the suction amount of the liquid, and finally, the suction is not performed at all. Therefore, when a significant amount of liquid remains in the bag, typically 20-50%, suction is stopped and replaced with a new bag. As described above, the conventional bag has a drawback that a considerable amount of liquid is wasted.

In order to eliminate this drawback, a mouthpiece has been developed that is attached to the mouth of the bag and guides the liquid inside. As such a base, the one shown in Japanese Utility Model Application No. 61-117145 is known. This conventional mouthpiece has a plurality of openings formed almost all over the longitudinal direction of the tubular body and the outer peripheral surface of the tubular body almost all over the longitudinal direction so as to be located near the peripheral edges of these openings. A liquid introducing body having a protrusion formed on each side is inserted into the bag so that the liquid therein is sucked.

[0005]

[Problems to be Solved by the Invention] However, even with the above-mentioned conventional mouthpiece, in order to ensure that the liquid in the bag can be taken out, the entire size must be increased, and it occupies the volume of the bag. It has the disadvantages of large space, poor bag storage efficiency, and a considerable amount of liquid remaining in the base.

Therefore, an object of the present invention is to provide a bag with a mouthpiece which can take out a sufficient amount of the liquid in the bag even when sucking the liquid in the bag through the suction tube and has a high liquid storage efficiency. Is to provide.

[0007]

[Means for Solving the Problems]

 The bag with a base of the present invention is formed of a flexible flat bag body, a base body made of synthetic resin fused to the opening of the bag body, and integrally formed with the base body, and is formed in the body of the bag. The liquid introducing body has a protruding predetermined length, and the liquid introducing body extends substantially parallel to the longitudinal direction and faces each other at a predetermined distance from each other. A pair of first vertical ribs having a pair of side surfaces extending in the radial direction from the end face to the outer end face, and along the longitudinal direction of the liquid introducing body so as to have a predetermined distance from these vertical ribs. The inner end surface and the outer end surface, which extend substantially parallel to each other and face each other at a predetermined interval, and extend radially from the inner end surface to the outer end surface, and have a radial distance larger than that of the first vertical rib. A pair of second vertical ribs having a pair of short side surfaces, and the liquid introduction body on the side surfaces of the first vertical rib. A plurality of lateral ribs projecting along the longitudinal direction at predetermined intervals and extending between the inner end face and the outer end face, and the direction in which the side face of the first vertical rib extends. Corresponds to the width direction of the bag main body, the extension direction of the side surface of the second vertical rib corresponds to the thickness direction of the bag main body, and is provided on the mouthpiece main body between the inner end surfaces of the first and second vertical ribs. A main flow path communicating with the main flow path is formed between side surfaces of the first and second vertical ribs, and a sub flow path communicating with the main body of the bag is formed.

[0008]

[Action]

 When using the liquid in the bag body, the liquid is sucked through the mouthpiece body. By this suction, the liquid in the bag main body is sucked into the main flow path through the sub flow path between the first vertical rib and the second vertical rib of the liquid introducing body, and from here, through the mouthpiece main body. Guided to the outside.

【Example】

 A bag with a mouthpiece according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a flexible flat bag body, which is formed of two sheets of synthetic resin sheet such as vinyl which are heat-sealed to each other at their peripheral edges, leaving a part of the upper end. .. A synthetic resin mouthpiece 2 is heat-sealed to a part (opening) of the upper end of the bag body 1, and as a result, the bag body 1 is liquid-tightly sealed.

The base 2 has a cylindrical main body 3 having an opening for pouring and suctioning at an upper end, and a flange portion 4 formed at a lower portion of the main body 3. Both side surfaces of the flange portion 4 are elongated and extend substantially parallel to both side ends of the bag body 1, and the extending ends intersect each other by being bent at a predetermined angle. Further, an edge portion 5 projecting from both sides of the flange portion 4 is formed at the upper end of the flange portion 4. Similar to the flange 4, the edge portion 5 is elongated toward both side ends of the bag body 1. In the mouthpiece 2, the peripheral side of the flange portion 4 is inserted into the opening portion at the upper end of the bag body 1, and the lower surface of the edge portion 5 is brought into contact with the upper end of the bag body 1, so that the flange portion 4 and the bag body 1 are The base 2 is attached to the bag body 1 by heat-sealing and.

As shown in FIG. 2, a liquid introducing body 10 is formed in the main body 3 of the mouthpiece 2 so as to extend downward, that is, to extend into the bag main body 1. The liquid introducing body 10 has a pair of first vertical ribs 11 made of thin pieces extending from the flange portion 4 substantially parallel to the longitudinal direction. The inner end surfaces 11a of the vertical ribs 11 face each other with a predetermined gap therebetween, and extend in parallel with the outer end surface 11b. A pair of side surfaces 11c extending in the radial direction (width direction of the bag body 1) from the inner end surface 11a to the outer end surface 11b is formed wider than the inner end surface 11a and the outer end surface 11b. On each side surface 11c, a plurality of ridges, that is, lateral ribs 12 that are provided so as to project at predetermined intervals along the longitudinal direction of the liquid introducing body and extend between the inner end surface 11a and the outer end surface 11b. Has been formed. In this embodiment, five lateral ribs 12 are formed on each side surface 11c with a predetermined interval. Similarly to the first vertical ribs 11, the liquid introducing body 10 extends from the flange portion substantially parallel to the longitudinal direction and extends from the flange portion. It has vertical ribs 13. The total length of the second vertical ribs 13 is set to be the same as that of the vertical ribs 11, but the width, that is, the radial length (the thickness direction of the bag body 1) is considerably short. In this embodiment, the width of the second vertical rib 13 is about 1/2 of the width of the first vertical rib 11, but the width is not limited to this as long as it is short. The inner end surfaces 13a of the vertical ribs 13 are spaced apart from each other by a predetermined distance. Thus, between the inner end surfaces 11a and 13a of the first and second vertical ribs 11 and 13, a main flow path communicating with the base body is formed. An outer end surface 13b of the vertical rib 13 extends in parallel with the vertical rib 13 and a side surface 13c formed between them is flat. Thus, between the side surfaces of the first and second vertical ribs 11 and 13, there is formed a sub-flow passage communicating with the main flow passage and the inside of the bag body. The vertical ribs 11 and the vertical ribs 13 are formed by integrally molding the main body 3 and synthetic resin. In FIG. 1, reference numeral 20 denotes a cap that is detachably attached to the main body 3 and is attached by, for example, screw connection to close the opening of the main body 3.

In the bag with a mouthpiece having the above-described structure, a highly viscous liquid such as grease is sealed inside and provided to the distribution mechanism. Then, when using the liquid therein, the cap 20 is removed, the suction tube connected to the vacuum pump is attached to the main body 3, and suction is performed. By this suction, the liquid in the bag main body 1 is guided into the main body 3 through the sub flow passage and the main flow passage. During this operation, the synthetic resin sheets of the bag body 1 are sucked in the direction of closely contacting each other near the body 3, but the flexible vertical ribs 11 and 13 prevent the close contact. It That is, during the suction operation, the first vertical rib 11 constantly vibrates due to the suction force and the liquid, so that the synthetic resin sheet is prevented from being brought into close contact with these entire surfaces. Further, the first vertical rib 11 and the second vertical rib 13 forming the sub-flow path are opened over the entire length in the longitudinal direction, and the horizontal rib 12 allows the flow path to be formed therebetween. Is ensured, the liquid can be smoothly sucked. Although the liquid can be efficiently sucked in this way, the vertical rib 13 extending in the thickness direction of the bag body is formed to have a narrow width, so that the entire mouthpiece can be formed in a small size. Therefore, the amount of residual liquid in the die is small.

In the above-described embodiment, the horizontal ribs 12 extend in the direction orthogonal to the extending direction of the vertical ribs 11, but they may be inclined at a predetermined angle and do not necessarily extend over the entire width of the vertical ribs. It doesn't have to be extended. In the above-described embodiment, the first vertical rib 11 and the second vertical rib 13 are connected only at the flange portion 4, and the inner end faces of these sub-flow paths are formed in the entire longitudinal direction. Separated across. However, in the present invention, as shown in FIG. 3, the first and second vertical ribs may be partially connected. In this embodiment, three ring-shaped connecting portions 14 are provided at three places in the upper, middle and lower parts. The outer peripheral surface of these connecting portions 14 and the inner peripheral surfaces of the vertical ribs 11 and 13 are connected. These connections may be made by synthetic molding of synthetic resin. Alternatively, they may be formed separately and connected with an adhesive or the like. By providing the connecting portion 14 in this manner, the strength of the vertical ribs 11 and 13 can be increased, so that these vertical ribs can be formed thin as necessary. In addition, handling becomes easy.

[0015]

[Effect of the device]

 When the liquid in the bag body is sucked out and taken out to the outside, the first and second vertical ribs and horizontal ribs prevent both sides of the bag body from adhering to each other and adsorption of the bag body and the liquid introducing body, A flow path is always secured. Therefore, the liquid can be sucked up to almost the end and does not remain in the bag body. Further, even if the whole is made small, a high suction efficiency of liquid can be obtained. In addition, the small size reduces the residual liquid. Since the first vertical rib having a large width is positioned along the width direction of the bag body and the second vertical rib having a small width is positioned along the thickness direction of the bag body, the liquid is stored. There is also an effect that the bag body does not become thick when not in use.
