Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is used in containers for use in beverages, medical use, etc., for example, filled with liquid contents including liquids, sols, gels or solids, such as sports drinks, fruit juice drinks, and fluid foods. The present invention relates to an outlet tool and a container with an outlet tool.
[0002]
[Prior art]
Conventionally, for example, containers that are filled with various liquids (contents) such as sports drinks and fruit juice drinks and can be taken out as necessary are known. As shown in FIG. 9, the container includes a container main body 51 composed of a flexible bag-like sheet 50, and a cylindrical outlet device 52 for taking out the fluid contents filled in the container main body 51. It is equipped with.
[0003]
When the upper edge portion 54 of the container main body 51 is sealed (sealed) by heat sealing, the take-out tool 52 extends into the container main body 51 from the attachment portion 55 that is sandwiched at the same time. The conducting portion 56 formed in a cross-shaped cross section and the mouth portion 57 projecting upward from the mounting portion 55 are integrally formed of synthetic resin. A cap 58 that closes the opening is detachably screwed into the mouth portion 57.
[0004]
[Problems to be solved by the invention]
Since the upper end portion of the conducting portion 56 connected to the attachment portion 55 has a cross-shaped cross section, the outlet tool 52 obstructs the flow when the contents are filled (especially a gel-like fluid such as jelly). When the contents are discharged (taken out), the contents tend to be finely crushed by the conducting portion 56, and thus the texture is poor.
[0005]
Therefore, an outlet tool 52 in which no rib is provided in the conduction portion 56 is also conceivable. However, in the case of the outlet tool 52, the container main body 51 becomes flat when the content is reduced, and thus it is impossible to secure a flow passage. There is a fear.
[0006]
Further, when sealing the outlet tool 52 to the upper edge 54 of the container body 51, the sheet pieces 50a and 50b of the container body 51 are sucked from both sides by the suction means 60 as shown in FIG. Thus, the upper edge portion 59 of the container body 51 is opened to a predetermined interval, and the outlet port 52 is inserted from the opened upper edge portion 59.
[0007]
However, since the suction means 60 cannot adsorb the upper edge end of the container body 51 for reasons such as securing a seal portion at the upper edge 59, the portion above the suction means 60 of the container body 51 is There is a risk of bending inside the main body 51.
[0008]
When the conduction portion 56 and the attachment portion 55 are inserted into the container main body 51, the upper end of the curved container main body 51 may be caught by the lower end surface of the attachment portion 55. As a result, heat sealing may occur in a state where the upper edge portion 59 is wound inside, and there is a problem that sealing cannot be performed reliably.
[0009]
Therefore, the present invention has been made to solve the above problem, and even if the contents are jelly or the like, the contents can be sucked without being crushed as much as possible, and the contents can be easily filled. When inserting into a main body, it makes it a subject to be able to insert smoothly and to seal an upper edge part reliably, without an attachment part being caught in the upper edge part of a container main body.
[0010]
[Means for Solving the Problems]
The present invention has been made as an outlet tool and a container with an outlet tool in order to solve the above-mentioned problems, and the feature as the outlet tool is made of a flexible sheet and accommodates fluid contents. A connecting portion 13 inserted into the container main body 1, a mounting portion 12 attached in a sealed manner to the upper edge portion 10 of the container main body 1, and a mouth portion 15 protruding upward from the mounting portion 12. In the outlet tool, the mounting portion 12 gradually tapers on both sides in the width direction of the container body 1 fixed to the upper edge portion 10 of the container body 1 and the flange portion 16 that contacts the upper end of the container body 1 from above. The connecting portion 17 is formed in a streamlined manner, and the conducting portion 13 tapers the connecting portion 17 so as to form an opening 19 communicating with the mounting hole 12 and the flow hole 24 formed in the mouth portion 15. Formed into a streamline From both sides only a pair of connecting portions 20 extending downwardly, and introducing plate part 21 from both of the connecting portion 20 is further extended, it consists projecting from the ribs 23 from both sides of the introducing plate 21, both the ribs 23, on at least the upper side, in that they have a part which is inclined in a direction in which the width toward the mounting portion 12 is widened.
[0011]
And, when inserting the outlet tool into the upper edge portion 10 of the container body 1 opened so as to have a predetermined distance from each other, the inclined ribs 23 guide the upper edge portion 10 in the opening direction, Since the upper edge portion 10 is expanded outward from the attachment portion 12, the attachment portion 5 can be prevented from being caught by the upper edge portion 10, and the outlet tool can be smoothly inserted to a predetermined position.
Note that the vertical direction of the outlet tool refers to the direction in which the container body is upright so that the outlet tool is positioned at the top when the outlet tool is attached to the container body. Further, the portion whose tip is inclined in the direction in which the width is increased toward the mounting portion 12 is that the rib 23 widens the upper edge portion 10 of the container body 1 when the outlet tool is inserted into the container body 1. The part which prevents an extraction tool from being caught on the upper edge part 10 is said.
[0012]
Moreover, since the contents enter the attachment portion 12 and the mouth portion 15 through the opening 19, they are not crushed finely by the conduction portion 13. Further, when filling the contents through the outlet tool, the contents can be easily filled into the container body 1 through the opening 19.
[0013]
The container as a container with an extraction tool is characterized in that the container body 1 is made of a flexible sheet and accommodates the flowable contents, and the extraction tool 3 according to claim 1 attached to the container body 1. located in the Turkey with a door. In such a case, the opening 19 and the inside of the container main body 1 can be communicated with each other even when the remaining amount of the contents is reduced and the container main body 1 is flat.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
1 to 7 show an embodiment of the present invention. In FIG. 4, reference numeral 1 denotes a container body in which a flexible sheet body 2 is formed in a bag shape having an upper opening. An outlet 3 for taking out liquids (contents) such as sports drinks and fruit juice drinks filled in the container body 1 is attached to the upper edge portion 10.
[0015]
The material of the sheet body 2 is not particularly limited as long as it has flexibility. For example, a laminated film of a synthetic resin film such as polyester or polyamide and an aluminum foil is excellent in storage stability of contents. It is preferable. The innermost layer of the laminated film is formed from a heat-fusible resin.
[0016]
Further, the sheet body 2 includes a pair of front and back sheet pieces 5a and 5b, and a gusset sheet in which both edges are sealed at the vertical edges 6 of both the front and back sheet pieces 5a and 5b and folded inside the container body 1. It consists of pieces 8a and 8b.
[0017]
The outlet tool 3 includes an attachment portion 12 that is sandwiched at the same time when the upper edge portion 10 of the container body 1 is sealed, and a conduction portion 13 that extends from the attachment portion 12 into the container body 1. A mouth portion 15 projecting upward from the mounting portion 12 is integrally formed of synthetic resin. A cap 9 that closes the opening of the mouth portion 15 is detachably screwed.
[0018]
The synthetic resin forming the outlet tool 3 has heat fusion properties with the inner surface of the laminated film, and for example, polyethylene or polypropylene can be used. In particular, it is preferable that both the innermost layer of the laminated film and the outlet 3 are made of linear low density polyethylene because of excellent sealing and strength.
[0019]
The attachment portion 12 includes a flange portion 16 having a substantially rectangular shape in plan view that comes into contact with the upper end of the container body 1 from above, and a cylindrical joint portion 17 fixed to the upper edge portion 10 of the container body 1. The outer peripheral surface of the joint portion 17 is formed in a streamline shape that gradually tapers on both sides in the width direction of the container body 1 so that the upper edge portions 10 of the sheet body are in close contact with each other without a gap.
[0020]
The conducting portion 13 includes a pair of connecting portions 20 extending downward from the joint portion 17, an introducing plate portion 21 extending further from both connecting portions 20, and a direction perpendicular to the introducing plate portion 21 ( And ribs 23 projecting from the front and back sheet pieces 5a and 5b).
[0021]
Between the connecting portions 20, an opening 19 is formed which communicates with a flow hole 24 formed in the attachment portion 12 and the mouth portion 15, and both connecting portions 20 have a shape that extends downward on both sides in the width direction. It has become. Accordingly, the upper end of the connecting portion 20 is connected to the inside of both ends of the joint portion 17, and the notch 22 is formed by the tip (lower end) of the joint portion 17 and the connecting portion 20.
[0022]
The introduction plate portion 21 has a maximum width at the upper end (connection portion with the connecting portion 20), and is gradually tapered toward the lower side (tip). Note that the maximum width of the introduction plate portion 21 is substantially equal to the length of both ends of the joint portion 17. Here, the tip of the fold of the gusset sheet pieces 8a, 8b of the container body (1) is the maximum width portion of the connecting portion 20 or the introducing plate portion 21 (the connecting portion between the introducing plate portion 21 and the connecting portion 20). It is folded inward so that it is near.
[0023]
The upper end of the rib 23 is equal to the upper surface of the introduction plate portion 21 (the peripheral surface of the opening 19). Further, as shown in FIG. 2, the leading end surface 23 b of each rib 23 has a wide inclined surface 23 c formed in a tapered shape whose width increases toward the upper side (the mounting portion 12 side), and the introduction plate portion 21. The mounting portion 12 is formed within a range α of an extended line L of the wide inclined surface 23c of the rib 23. The narrow inclined surface 23d is connected to the upper surface.
[0024]
The present embodiment is configured as described above. Next, a case where the container is manufactured will be described. The container main body 1 is manufactured from a cylindrical and long sheet by a bag making machine or the like. The container main body 1 has an upper edge portion 10 as shown in FIGS. It is conveyed in an opened state by 25 suction. The opening means 25 adsorbs the position where the upper portions of the front and back sheet pieces 5a and 5b of the container body 1 are left.
[0025]
On the other hand, the take-out tool 3 is conveyed while being suspended with the flange 16 locked by a suspension means (not shown). Then, the container main body 1 with the upper edge portion 10 opened and the takeout tool 3 approach each other, and the tip of the conducting portion 13 of the takeout tool is inserted into the container main body 1. Since the rib 23 of the conducting portion 13 has a tip end surface 23b formed in a tapered shape, if the upper edge portion 10 of the container body 1 is curved inward, the container body 1 and the outlet 3 may be Even if the position is slightly shifted, the conducting portion 13 is inserted into the container body 1 while the rib 23 serves as a guide means and the upper edge portion 10 is expanded (see FIG. 5).
[0026]
And since the upper edge part 10 is expanded outward from the diameter of the junction part 17 of an extraction tool, the junction part 17 does not catch on the upper edge part 10 of the container main body 1, and the junction part 17 is the container main body 1. FIG. Is smoothly inserted to a position corresponding to the upper edge portion 10.
[0027]
Furthermore, the upper edge portion 10 of the container body 1 is heat-sealed together with the joint portion 17 of the outlet 3 by the heat sealer 27. At this time, since the upper edge portion 10 of the container body 1 is not folded inward, the sealed state is ensured. When the container body 1 is filled with the contents, the contents are filled into the container body 1 from the mouth portion 15 of the outlet 3, and after filling, the cap 9 is screwed into the mouth portion. 15 is closed. In addition, since the opening 19 connected to the flow hole 24 is formed at the time of filling, it can be filled smoothly.
[0028]
Next, when the outlet 3 is used as a suction tool when the liquid is taken out, if the container 9 is sucked from the mouth portion 15 after the cap 9 is removed, the container body 1 has flexibility, so the front and back sheet pieces By approaching 5a, 5b, the liquid in the container main body 1 can be sucked up. Also, when the contents are jelly, since the opening 19 is provided, the jelly is not easily broken and can be sucked (drinked) while maintaining a preferable texture. Furthermore, in the case of the content which has granular solids, such as a pulp, it can suck | suck smoothly.
[0029]
Even when the remaining amount in the container main body 1 is further reduced and the container main body 1 is contracted and deformed, the inner surface of the container main body 1 comes into contact with the respective distal end surfaces of the introduction plate portion 21 and the rib 23, and the container main body 1 and the introduction plate Since a suction channel can be formed between the portion 21 and the rib 23, the content passes through the suction channel and is led to the mouth portion 15.
[0030]
Further, when the remaining amount of the contents in the container body 1 decreases, the container body 1 becomes flat as shown in FIG. 7 (a state in which the gusset is folded and in close contact). The narrow space remaining at the tip of the fold can be sucked up, but the maximum width portion of the introduction plate portion 21 (although both sides of the joint portion 17 are formed in a streamlined shape gradually tapering, has a predetermined thickness) Since the portion) is formed, the contents can be sucked up between the portion and the tip of the fold of the gusset, and even a slight content with relatively low fluidity has good suckability.
[0031]
Further, when the outlet 3 is used as a spout, the contents are passed through the opening 19 and the mouth portion 15 by tilting or inverting the container body 1 so that the mouth portion 15 faces downward. Can be drained.
[0032]
The present invention is not limited to the above-described embodiment. For example, as shown in FIG. 8A, the shape of the opening 19 of the conducting portion 13 may be a semicircular shape. Further, the rib 23 does not need to be inclined over the entire length, and the upper side of the rib 23 may be inclined as shown in FIG.
[0033]
Further, as shown in FIGS. 8 (c) and 8 (d), the introduction plate portion 21 is provided with a wide portion over its entire length, and projecting ribs 21a are formed on both sides thereof to improve the suction of the residual liquid in the state of FIG. It can be improved.
[0034]
Further, the tip surface 23b of the rib 23 is formed in a linear taper shape. However, the tip surface 23b may be curved in a convex shape or in a concavo-convex shape. When inserting, the rib 23 should just be able to expand the upper edge part 10 of the container main body 1, and an outlet tool may not be caught by the upper edge part 10. FIG.
In addition, the container main body 1 to which the outlet tool 3 is attached does not necessarily include a gusset.
[0035]
【The invention's effect】
As described above, the conducting portion of the outlet tool of the present invention has a pair of connecting portions extending downward from the mounting portion so as to form an opening that communicates with the through hole formed in the mounting portion and the mouth portion. Part, an introduction plate part further extending from both connecting parts, and ribs projecting from both sides of the introduction plate part, and both ribs have their tips widened toward the attachment part. Since the attachment portion and the mouth portion are included in the range of the extension line of the tip of the inclined rib having a tapered portion, when inserting the outlet tool into the upper edge portion of the container body, There is an advantage that the takeout tool can be smoothly inserted to a predetermined position without the attachment part being caught by the upper edge part, and the sealing state of the upper edge part of the takeout tool and the container body can be ensured.
[0036]
In addition, there is an advantage that the contents can be sucked through the opening without being finely crushed, the texture is good, and the contents can be easily filled.
