Description

  The present invention relates to a packaging pouch with a nozzle, which facilitates the opening of a nozzle portion for pouring contents, thereby ensuring stable dispensing properties.

A packaging pouch with a nozzle is used for refilling, such as sealing and packaging a fluid content such as liquid or powder and transferring it to another container via a nozzle portion.
This packaging pouch with a nozzle is, for example, a standing pouch, and has a bottom portion that can be unfolded by folding the bottom pouch piece between a plastic film-like surface pouch piece and a back surface pouch piece and then heat-sealing the periphery. In addition, a space for filling the contents is formed, and a nozzle portion for pouring is formed in the upper corner portion of the pouch, or in the upper central portion or the like.
The dispensing nozzle portion is formed, for example, so as to narrow the width of the void toward the opening scheduled position such as an easy opening processing portion, and the peripheral portion is heat sealed.

In such packaging pouches with nozzles, there is a problem that the surface pouch pieces and the back surface pouch pieces with overlapping nozzle portions are in close contact with each other and it is difficult for the contents to flow out, and various proposals have been made to secure the flow path. ing.
For example, in a packaging bag with a dispensing function disclosed in Patent Document 1, an opening assisting mechanism and an anti-bending mechanism adjacent to or adjacent to the opening assisting mechanism are formed at the portion that becomes the spout after the packaging pouch is opened. Therefore, the spout can be easily formed, and the contents can be easily taken out while keeping the flow by preventing the spout from being bent.
By such an embossing opening assist mechanism, the flow path can be secured, and when the contents reach the nozzle portion, the flow path is further expanded by the weight of the content liquid and the pressure, and the contents can be easily taken out.

Japanese Patent Laid-Open No. 11-11498

However, if you want to make the nozzle part thinner, such as when you want to refill a small-diameter container with such a packaging pouch with a nozzle, the width of the heat seal part at the peripheral part of the nozzle part is to ensure sealing performance. Since it cannot be less than a certain width, the width of the space that becomes the flow path is narrowed, and the width of the heat seal portion is relatively widened.
This heat seal part is highly rigid because it is integrated with the front and back pouch pieces overlapped, especially in the vicinity of the nozzle part tip, because the heat seal part is formed surrounding the tip and both sides of the void. There is a problem that the rigidity is higher and the action of maintaining the nozzle portion in a flat state is larger, and the contents cannot be stably taken out because it is difficult to spread as compared with the nozzle portion having a normal width.
In addition, it has been proposed to secure the flow path by three-dimensionally forming the void of the nozzle part into a circular cross section, etc., but it can be restored if the pouch piece on one side is crushed by the force from the outside. There is also a problem that it is difficult to take out the contents.
On the other hand, in order to secure the flow path of the nozzle part, there is also a pipe-type packaging pouch in which a pipe is inserted and incorporated in advance in the void of the nozzle part, but the manufacturing process is increased compared to the packaging pouch with an all-film nozzle. However, when the pipes of the nozzle portion overlap during storage or transportation before filling the contents, there is a problem that it is difficult to stack and the space efficiency is poor.

  The present invention has been made to solve the above-described problems of the prior art, and is capable of prompting the opening of the nozzle portion for pouring the contents without having to incorporate a pipe into the nozzle portion. It is an object of the present invention to provide a packaging pouch with a nozzle capable of ensuring the above.

  As a result of diligent research and development in order to solve the problems of the above-mentioned conventional technology, the peripheral portion of the void is heat-sealed in the nozzle portion of the packaging pouch with the nozzle, with the two films being overlaid. If you try to secure the flow path open when opening with the tip of the opening as the opening position, the heat seals on both sides (usually top and bottom, etc.) of the two openings are brought close to each other. It is necessary to deform the film so that the film spreads in the direction in which it is to be done. For this purpose, it is effective to deform so that the heat seal part etc. falls to one side or to extend the heat seal part. In order to solve the problem by spreading the nozzle opening in advance by brazing such a deformation on a heat seal part or the like, the specific configuration of the present invention is completed. , It is as follows.

Hereinafter, embodiments of a packaging pouch with a nozzle according to the present invention will be described in detail with reference to the drawings.
As shown in FIG. 1, a packaging pouch 10 with a nozzle according to the present invention is, for example, a standing pouch, and a bottom pouch piece 13 is folded and sandwiched between a plastic film-like surface pouch piece 11 and a back surface pouch piece 12. Fill the bag-like contents with a bottom that can be opened and opened by forming the left and right side seals (side seals) 14 and 14 and the bottom seal 15 by heat-sealing the periphery. An empty space 16 is formed, and a dispensing nozzle portion 17 is formed in the upper corner portion.
The dispensing nozzle portion 17 is formed with throat portions 18 and 19 that are curved and cut out on both sides, so that a void 16 is formed toward a planned opening position such as an easy opening portion 21 provided with a notch 20. The opening portion is provided with a tab for opening (opening tip portion) 22 at the seal portion that closes the nozzle portion 17 on the tip side of the easy-opening processing portion 21. Te Yes, cavity 16a reaching the opening tab 22 beyond the easily openable processing unit 21 is formed.
The packaging pouch 10 with a nozzle is filled with contents from the opening on the upper side, and then the upper side is heat-sealed to form a sealed standing pouch.

  In this packaging pouch 10 with a nozzle, in order to facilitate the pouring from the nozzle portion 17, the front and back surface pouch pieces 11 and 12 on which the nozzle portion 17 overlaps are projected outward along the central axis of the nozzle portion 17. The ridge line part 23 is formed, is formed in a straight line from the nozzle part 17 to the inside of the pouch body part, and both sides of the ridge line part 23 are flat bulging surfaces. Is different.

  In this packaging pouch 10 with a nozzle, in addition to the ridge line portion 23 of the nozzle portion 17, there are two linear body ridge line portions 24, 24 that protrude outward on the front and back surface pouch pieces 11, 12 of the pouch body portion. Are bent so as to surround the throat portion 18 on the side portion. Both sides of the trunk ridges 24 and 24 are formed into a bulging surface 26 by three-dimensional processing or the like, and one of the outer edges of the bulging surface 26 extends along the throat portion 18 of the pouch, and the other is curved so that the throat portion from the outside. 18 is enclosed. The contents filled by the trunk ridges 24 and 24 and the bulging surfaces 26 and 26 are promoted to be guided to the opening of the nozzle portion 17 or the shape deformation when bulging is restricted to some extent, A force is applied to urge the opening of the unsealed nozzle portion 17 when pouring out.

Further, as a packaging pouch 10 with a nozzle, the front and back surface pouch pieces 11 and 12 of the nozzle portion 17 are each formed with a convex ridge line portion 23 on both sides, and both sides are made flat bulging surfaces. As shown, the back pouch piece 12 of one of the front and back pouch pieces 11, 12 has a base end side on the space 16 a of the opening tab 22 on the distal end side beyond the easy opening processing portion 21 of the nozzle portion 17. The ridge line portion 23 is the end, and a valley fold portion 27 is formed on the extension of the end of the ridge line portion 23 up to the tip of the space 16a of the opening tab 22, and on both sides of the valley fold portion 27 toward the nozzle tip. The folds 28 and 28 are formed on the open space 16 a of the opening tab 22 in a V shape.
The valley fold portion 27 is not limited to a three-dimensional shape, and may be a portion in which the space between the V-shaped valley fold portions 28 and 28 is relatively recessed.

Moreover, as the packaging pouch 10 with a nozzle, it replaces with the form of FIG. 2, and as shown in FIG. 3, the easy opening process of the nozzle part 17 is carried out to one back surface pouch piece 12 of the front and back surface pouch pieces 11 and 12. The ridge line portion 23 is terminated at the middle portion of the void 16a of the opening tab 22 on the distal end side beyond the portion 21, and the proximal side from the distal end of the void 16a of the opening tab 22 on the extension of the termination of the ridge line portion 23 The valley folds 29, 29 may be formed on the empty space 16 a of the opening tab 22 in an inverted V shape that spreads out.
In addition to forming convex ridges 23 on both sides of the void 16a of the opening tab 22, the valley fold 27 and the mountain folds 28, 28 are combined on one side, or the valley fold 29 , 29 can be surely ensured the space 16a of the opening tab 22 and, thereby, the space when the nozzle portion 17 is opened can also be secured.

Next, in this packaging pouch 10 with a nozzle, the contents are placed on either the peripheral seal part and the opening tab 22 of the nozzle part 17, or the peripheral seal part 14 a and the opening tab 22 of the nozzle part 17. An opening promoting means 30 for urging the opening of the nozzle portion 17 opened by the easy opening processing portion 21 after filling is provided. For example, as shown in FIG. 4B, the front and back surface pouch pieces 11 and 12 of the nozzle portion 17 are provided. The ridge line portions 23, 23 on both sides are surely opened by pushing outward.
As shown in FIGS. 1 to 4, the opening promoting means 30 is configured by forming a linear fold portion 31 on the extension of the ridge line portion 23 of the opening tab 22.
By forming the linear fold portion 31 on the opening tab 22 and tearing it with the opening tab 22 from the notch 20 at the end of the easy opening processing portion 21, the fold portion 31 is formed on the opening tab 22. Is formed, the folded tab of the opening tab 22 remains in the space 16 of the nozzle portion 17 of the packaging pouch 10 with the nozzle. For example, as shown in FIG. A force acts so as to approach, and thereby the deformation is urged so that the ridge lines 23 and 23 of the void 16 of the nozzle portion 17 spread outward, and a large opening is formed.
Similarly, not only the outwardly protruding ridge line portions 23 are formed on both sides of the space 16a of the opening tab 22, but in particular, the valley fold portion 27 and the mountain fold portion 28 on one side shown in FIGS. 28, or the valley fold portions 29, 29, the nozzle portion 17 has different shapes on both sides, so that the front and back surface pouch pieces 11, 12 of the void 16a are in close contact with each other when the fold portion 31 is formed. It is possible to prevent the sheet from being rubbed in the same folding direction. Furthermore, even if the empty space 16a of the opening tab 22 is crushed, it can be avoided that the front and back surface pouch pieces 11 and 12 are in close contact with each other. The ridge line portions 23 and 23 on both sides of the front and back surface pouch pieces 11 and 12 can be surely opened by pushing outward.
Further, after the opening, the contents are passed through the nozzle portion 17 so that the opening is pushed and spread more easily.

Further, as the opening promoting means 30, as shown in FIGS. 1, 5, and 6, a linear seal extending in the width direction is provided on the curved seal portion 14 a of the throat portion 18, which is a seal portion at the periphery of the nozzle portion 17. It can also be configured by forming a polygonal line portion 32. Here, a plurality of, for example, two polygonal line portions 32, 32 are formed by bending points 25 between the ridge line portion 23 and the trunk ridge line portion 24 and the trunk ridge line portion. 24 and 24 are formed at two locations of the seal portion 14a curved in the direction connecting to the bending point 25 at the shortest distance from the outside so that the directions of the broken lines are the same. As long as the polygonal line direction is the same for a plurality of lines, it may be a valley fold line or a mountain fold line.
By forming the broken line portion 32 in such a direction that intersects the seal portion 14a as such an opening promoting means 30, an action of shifting the front and back surface pouch pieces 11 and 12 of the nearby space 16 by folding is generated. A force acting on the valley side of the broken line portion 32, for example, the surface pouch piece 11 side, is exerted so that the seal portion 14a is tilted, and in particular, the deformation between the two broken line portions 32, 32 is caused to fall. A force that bends the entire nozzle portion 17 slightly downward acts.
As a result, the upper and lower seal portions of the nozzle portion 17 approach each other, and the ridge line portions 23 and 23 are deformed so as to push outward, and the opening of the nozzle portion 17 is surely expanded to secure a flow path.
Further, when the entire nozzle portion 17 is deformed so as to be bent slightly downward, the body ridge line portions 24, 24 are linearly formed in the pouch body portion and bent at two bending points 25, 25 in advance. As a result, the spread direction shifts between the bending points, the deformation direction of the front and back surface pouch pieces 11 and 12 can be restricted, and the nozzle portion 17 can be easily bent downward to make the upper and lower seal portions 14a and 14a. And the spread of the ridges 23 and 23 to the outside can be maintained.
Thereby, the nozzle part 17 after opening can be opened more reliably.

Such a broken line portion 32 is preferably formed such that the outer end portion reaches the outer edge of the seal portion 14a, and the inner end portion is formed so as to protrude beyond the seal portion 14a into the space 16 portion. Also good.
Further, as shown in FIG. 5B, the polygonal line portion 32 may be formed so that the cross-sectional shape is a sharp point such as a triangle, or may be formed so as to protrude smoothly, such as a semicircle. .

  Further, instead of the broken line portion 32 as the opening promoting means 30, it can be constituted by a dotted pressing portion 33 as shown in FIG. 5A, and only one point is formed at the formation position of the broken line portion 32. Alternatively, a plurality of lines can be formed on the line along the formation position of the broken line portion 32, and a plurality of, for example, two broken line portions 32 and 32, at a plurality of spaced positions, for example, at two formation positions. Only one point or a plurality of points may be formed. Also when comprised by the dotted | punctate press part 33, it is preferable to form by pressing from the same direction similarly to the case where it comprises with a broken line part.

  Moreover, the formation position of the broken line part 32 and the pressing part 33 of the opening promoting means 30 is not limited to the case where the sealing part 14a is curved in the direction connecting the bending points 25 and 25 with the shortest distance from the outside, but the sealing part. You may make it form in the position shown by the dotted line in FIG. 5, such as the nozzle part 17 front end side of 14a.

  Moreover, although the formation position of the broken line portion 32 and the pressing portion 33 of the opening promoting means 30 is formed on the curved seal portion 14a of the throat portion 18, it is sufficient if the entire nozzle portion 17 can be bent downward, It may be formed on the seal portion of the cut-out throat portion 19 or may be formed on both sides, or may be a combination of a broken line portion or a pressing portion.

  In addition, the fold part 31 formed on the opening tab 22 as the opening promoting means, the fold line part 32 and the pressing part 33 formed on the seal part 14a of the nozzle part 17 can be freely combined and employed. Either of them can be employed alone.

  Furthermore, the nozzle part of the packaging pouch with the nozzle is not limited to the one provided in the corner part of the pouch as shown in the illustrated example, and may be provided in other positions such as the central part of the upper side, and the shape thereof is also on both sides. It may be provided with a cut-out throat part, or provided with a cut-out throat part only on one side. In any case, the opening can be promoted by providing an opening promoting means.

  Moreover, there is no restriction | limiting in particular in the manufacturing method of such a packaging pouch with a nozzle, and the processing method of the opening promotion means, It can manufacture and process by applying the manufacturing method etc. of a conventional pouch.
