Description

  TECHNICAL FIELD The present invention relates to a bag container formed by molding a synthetic resin container body having a trunk portion having a bottom portion and a spout forming portion using a mold.

  Conventionally, a self-standing bag or the like that is formed by molding using a mold such as blow molding, and includes a bottom portion and a trunk portion that includes a spout forming portion, and can be placed on a placement surface with the bottom portion as a placement surface. There are known bag containers. In these bag containers, a spout is formed by cutting a spout formation part, and the enclosed contents are poured out.

In this case, it is troublesome to perform the operation of cutting the spout forming portion using a knife or scissors, which is troublesome for an unfamiliar user. For this reason, the spout forming portion is provided with an annular easily breakable portion by a thin cut portion or a narrow groove-shaped recess and a knob piece, and the easy breakable portion is broken by an operation of tearing or tearing. A blow-molded container that can easily perform an operation of forming an opening at an outlet is disclosed (for example, see Patent Document 1).

Thus, an opening knob piece 17 having a locking hole 24 is connected to the upper surface of the excision scheduled portion 16 and is integrally formed. Here, the surface along the parting line 21 is a virtual surface including the parting line 21.

  In the first embodiment, the opening knob piece 17 is provided so as to protrude from the joint base end portion 22 and the joint base end portion 22 to one side with respect to the central axis X of the spout forming portion 13. It has a flat plate shape having a substantially oval shaped overhanging locking portion 23 in which a portion overlapping with the outlet forming portion 13 is cut out.

  The joint base end portion 22 is a portion connected along the outer circumferential surface of the planned excision portion 16, and the portion connected to the upper surface of the planned excision portion 16 is a thick stepped portion 22 a. By providing the thick stepped portion 22a in the portion of the joint base end portion 22 that is continuous with the upper surface of the planned cutting portion 16, the connecting portion with the planned cutting portion 16 is effectively reinforced, and an opening knob piece is provided. The portion of the spout forming portion 13 opposite to the central axis X of the spout forming portion 13 is the portion where the overhanging locking portion 23 of the to-be-cut portion 16 overhangs when pulling up 17 to break the easily breakable portion 15. In addition, it can be efficiently transmitted as a compressive load. As a result, the side where the overhanging locking portion 23 overhangs the end 15a of the easily breakable portion 15 located on the opposite side of the center axis X of the spout forming portion 13 with the end 15a of the spout forming portion 13 as a fulcrum. Breaking is started from the end portion 15b of the easily breakable portion 15 located on the side where the overhanging locking portion 23 protrudes with respect to the central axis X so that the easily breakable portion 15 can be broken more smoothly. It becomes possible.

  The overhang | locking latching | locking part 23 is a part provided so that it might protrude from the joining base end part 22 to the upper part of the shoulder part 19 of the container main body 11, and the outer peripheral edge part is the thick edge part 23a. . The overhanging locking portion 23 is formed with an oval locking hole 24 whose opening peripheral edge is edged by a thick edged portion 24b at a portion of the overhanging tip.

  Further, in the present embodiment, the elliptical locking hole 24 is arranged so that the minor axis direction Z thereof is substantially along the circumferential direction L centering on the end 15 a serving as a fulcrum of the easily breakable portion 15. Yes. That is, the minor axis of the elliptical locking hole 24 is an axis that substantially coincides with the tangent of the circumference centered on the end 15a. As a result, when an operation of inserting and locking the finger into the locking hole 24 and pulling up the first knob piece 17 is performed, the finger pad is positioned at the portion 24z where the curve of the locking hole 24 is most loose (the short axis direction Z and the wall thickness). Can be easily applied in the circumferential direction L around the end 15a serving as a fulcrum of the easily breakable portion 15 while pressing against the inner peripheral surface of the edge portion 24a 15 can be broken more smoothly.

  In the first embodiment, the oval shaped locking hole 24 is formed with an opening so that, for example, the minor axis is about 10 to 15 mm and the major axis is about 10 to 20 mm. The axial direction Z is disposed along the circumferential direction L centering on the end portion 15 a serving as a fulcrum of the easily breakable portion 15. In the first embodiment, the substantially oblong overhanging locking portion 23 and the elliptical locking hole 24 of the unsealing knob piece 17 are surfaces whose major axis direction Y is parallel to the placement surface P1. It is inclined at an inclination angle θ of preferably 5 to 35 degrees with respect to the surface P2 on which the easily breakable portion 15 is formed (which is a surface perpendicular to the central axis X of the spout forming portion 13). It is provided so that it may become the direction.

  Since the inclination inclination angle θ is 5 to 35 degrees, the overhanging locking portion 23 of the to-be-removed portion 16 stretches the lifting load when the opening knob piece 17 is pulled up to break the easily breakable portion 15. The delivery side can be efficiently transmitted as a compressive load to a portion opposite to the central axis X of the spout forming portion 13. As a result, the side where the overhanging locking portion 23 overhangs the end 15a of the easily breakable portion 15 located on the opposite side of the center axis X of the spout forming portion 13 with the end 15a of the spout forming portion 13 as a fulcrum. Breaking is started from the end portion 15b of the easily breakable portion 15 located on the side where the overhanging locking portion 23 protrudes with respect to the central axis X so that the easily breakable portion 15 can be broken more smoothly. It becomes possible, and the advantage that the lifting load can be reduced can be obtained.

  The preferred range of the angle θ will be described in detail. The angle θ is preferably 35 degrees or less, more preferably 30 degrees or less, and even more preferably 25 degrees or less from the viewpoint of reliably opening without causing torsional fracture. On the other hand, from the viewpoint of reducing the opening force, 5 degrees or more is preferable, 10 degrees or more is more preferable, and 20 degrees or more is more preferable.

  And according to the bag container 10 of this 1st Embodiment provided with the above-mentioned structure, an abdomen of a finger | toe is latched in the locking hole 24 provided in the opening knob piece 17 of the spout formation part 13, and the opening knob piece 17 is provided.

The elliptical short axis direction Z is arranged along the circumferential direction L with the end 15 a serving as the fulcrum of the easily breakable portion 15 as the center. Therefore, when performing the operation of breaking the easily breakable portion 15 by inserting and locking the finger into the locking hole 24 and pulling up the opening knob piece 17, the bending of the locking hole 24 becomes the most loose in the abdomen of the finger. In other words, it is naturally guided so as to be locked from the inner side to the peripheral portion 24a of the portion (24z) intersecting with the minor axis direction Z. Thereby, with respect to the central axis X of the spout forming portion 13, toward the circumferential direction L centering on the end portion 15 a of the easily breakable portion 15 located on the side opposite to the side where the unsealing knob piece 17 projects. The pulling force of the opening knob piece 17 can be easily applied by the abdomen of the finger, and the pulling force can be efficiently transmitted to the excision scheduled portion 16 as a force for breaking the easily breakable portion 15 to open the spout. It becomes possible to perform the forming operation easily and smoothly.

  In the first embodiment, since the peripheral edge of the opening of the locking hole 24 is edged by the thick edge portion 24b, the abdomen of the finger is connected to the short axis direction Z via the thick edge portion 24b. It is possible to press against the peripheral portion 24a of the intersecting portion, and thereby it is possible to apply a force for pulling up the opening knob piece 17 in a more stable state.

  FIG. 3 shows a main part of a bag container 30 according to a preferred second embodiment of the present invention. In the bag container 30 of the second embodiment, in addition to the configuration of the bag container 10 of the first embodiment, the unsealing knob piece 17 is a party by a molding die with respect to the central axis X of the spout forming portion 13. The shoulder portion 19 of the trunk portion 12 adjacent to the spout forming portion 13 is provided on the shoulder portion 19 adjacent to the spout forming portion 13 on the side projecting in the diametrical direction (side edge direction of the front portion 12A or the rear portion 12B) along A presser knob piece 18 is provided so as to protrude upward while being separated from the spout forming portion 13.

  That is, in the second embodiment, the presser knob piece 18 is provided in a flat plate shape on the surface along the parting line 21 by the molding die, like the opening knob piece 17. The presser knob piece 18 is opened in a state where it is separated from the shoulder portion 19 of the body portion 12 of the container main body 11 while maintaining a space of preferably about 8 to 12 mm between the peripheral surface of the spout forming portion 13. It is provided so as to protrude upward with an unbuffered height with the overhanging locking portion 23 of the knob piece 17. By maintaining an interval of about 8 to 12 mm between the presser knob piece 18 and the peripheral surface of the spout forming portion 13, for example, the pouring of the spout forming portion 13 formed by removing the planned cutting portion 16. When the contents filled and accommodated in the container body 11 are poured from the outlet through the mouth and neck of another container, the mouth and neck of another container is placed between the spout forming part 13 and the presser knob piece 18. It is possible to pour the contents into another container in a stable state by placing the parts between them.

  Further, in the present embodiment, the presser knob piece 18 is provided with its center line C arranged in parallel or substantially parallel to the central axis X of the spout forming portion 13. Further, it is desirable that the presser knob piece 18 has a thick edge portion 18a at the peripheral portion, and the front and back surfaces inside the edge portion 18a are appropriately slipped by embossing or the like. .

  And according to the bag container 30 which concerns on this 2nd Embodiment, in addition to the effect similar to the bag container 10 of the said 1st Embodiment being show | played, with respect to the central axis X of the spout formation part 13 The presser knob piece 18 is provided on the shoulder 19 of the body portion 12 adjacent to the spout forming portion 13 on the side where the unsealing knob piece 17 projects, and protrudes upward from the spout forming portion 13. Therefore, for example, when the bag container 10 is erected and placed on the placement surface, the finger is locked in the locking hole 24 and the opening knob piece 17 is pulled up. A moment of a considerable magnitude that resists the moment force caused by the lifting load with the end 15a of the easily breakable portion 15 located on the opposite side to the side where the overhanging locking portion 23 projects from the center axis X. Power can be easily obtained. That is, it is provided on the shoulder 19 at a distance equal to or more than the distance (the distance between 15a and 24z) from the end 15a serving as a fulcrum to the peripheral portion 24a of the locking hole 24 serving as the point of action of the lifting load to the opening knob piece 17. By holding the pressed presser knob piece 18 and pressing the bottom portion 14 of the bag container 10 against the placement surface through the presser knob piece 18, a moment force having a considerable magnitude against the moment force caused by the lifting load is obtained.
