Description

  The present invention relates to a bag-like container filled with contents such as foods, beverages, cosmetics, and detergents, and more particularly, to a bag-like container suitable for use for filling contents for refilling.

In recent years, bag-like containers such as pouches are frequently used as containers filled with contents such as foods, beverages, cosmetics, and detergents and displayed in stores.
FIG. 7 is a perspective view showing a conventional bag-like container.
The bag-like container 100 shown in this figure is formed by applying an edge seal 102 to front and back soft packaging materials 101. A nozzle portion 104 that protrudes obliquely upward is formed at the upper corner of the body portion 103 that is filled with the contents, and the nozzle portion 104 is cut off along the cut line 106 to remove the nozzle portion 104. A spout is formed at the tip of the portion 104, and the contents can be poured out.

FIG. 8 is an explanatory diagram showing a procedure for refilling contents in a conventional bag-like container.
As shown in this figure, when the contents of the bag-like container 100 are refilled into a bottle container 107 or the like, first, the tip portion 105 of the nozzle portion 104 is cut along the cut line 106.
Next, as shown in FIG. 8A, the bag-like container 100 and the bottle container 107 are held by hand, and the nozzle part 104 of the bag-like container 100 is aligned with the mouth part 108 of the bottle container 107 while tilting them. Then, start refilling the contents gradually.

Next, as shown in FIG.8 (b), the inclination of the bag-like container 100 is enlarged and the amount of contents to be poured out is increased. At this time, it is preferable to insert the nozzle portion 104 of the bag-like container 100 into the mouth portion 108 of the bottle container 107 so that the nozzle portion 104 does not come off from the mouth portion 108.
When the content in the bag-like container 100 is low, as shown in FIG. 8 (c), the bag-like container 100 is inverted almost vertically, and the contents in the bag-like container 100 are poured out without waste. Let
The refilling operation of the contents from the bag-like container 100 to the bottle container 107 is completed by the above procedure.

However, the conventional bag-like container 100 has a problem that the contents are easily spilled out of the bottle container 107 when the contents are refilled.
As the first cause, as shown in FIG. 8A, before the nozzle part 104 is inserted into the mouth part 108 of the bottle container 107, the outflow of the contents can be mentioned. In particular, since the contents may flow out vigorously at the beginning of the pouring of the contents, the contents may be spilled if the positions of the nozzle portion 104 and the mouth portion 108 are slightly shifted.

  A second cause is that the shape of the bag-like container 100 is unstable. In particular, during the refilling of the contents, the bag-like container 100 is easily deformed due to the decrease in the contents, and the support of the bag-like container 100 becomes unstable. There is a possibility that the contents will spill out.

In view of this, a bag-like container has been proposed in which a branch portion is formed in the body portion of the bag-like container and the contents are poured out using this as a nozzle portion (see, for example, Patent Document 1).
According to the bag-shaped container configured as described above, since the bag-shaped container can be tilted after the nozzle portion is inserted into the mouth of the bottle container, the possibility of spilling the contents decreases. Further, since it is not necessary to tilt the bottle container, the refilling operation can be performed with one hand.
Japanese Patent Laid-Open No. 10-218199

  However, in the bag-like container shown in Patent Document 1, the problem due to the first cause described above can be avoided, but the problem due to the second cause cannot be avoided. That is, even if the nozzle portion is branched, if the support of the bag-like container is unstable, the nozzle portion comes off from the mouth of the bottle container.

  Moreover, in the bag-shaped container shown by patent document 1, in the case of the refilling operation | work of a content, a nozzle part may close and it may become difficult to pour the content. This is because when the contents are moved from the body part to the nozzle part in order to pour out the contents, the base part of the nozzle part swells, and at the same time, a biasing force acts in the direction of closing the spout, and the inner surface of the nozzle part is This is because they are in close contact.

  The present invention has been considered in view of the above circumstances, and when refilling the contents into a bottle container or the like, the bag can prevent the contents from spilling and stably pour out the contents. The purpose is to provide a container.

  In order to achieve the above object, the bag-shaped container of the present invention is a bag-shaped container formed by applying edge seals to the front and back soft wrapping materials, and a body portion filled with contents, and the body portion. The nozzle part is branched from one or both of the front and back, and the tip part is provided with a nozzle part serving as a spout for the contents, and a recess formed at a position below the branch line of the nozzle part on both side parts of the body part It is as.

  If a bag-shaped container is comprised in this way, a bag-shaped container can be supported with sufficient stability by putting a finger on the concave portions on both sides. Thereby, when the contents are refilled into a bottle container or the like, it is possible to avoid the inconvenience that the nozzle part is detached from the mouth part of the bottle container and the contents are spilled.

In addition, when the body part is pressed from both sides with a finger hung on the recess, this pressing force acts in the direction of expanding the nozzle part, so that the inner surface of the nozzle part is prevented from sticking and the contents are stably It becomes possible to dispense.
Further, when the bag-like container is lifted by placing a finger on the concave portion, the load of the contents acts in the direction of expanding the nozzle portion, so that the effect of preventing adhesion of the nozzle portion can be further enhanced.

In the bag-like container of the present invention, the distance from the branch line to the recess is 3 mm to 40 mm.
If the bag-like container is configured in this manner, the bag-like container can be supported in the vicinity of the nozzle portion, so that the position of the nozzle portion is stabilized and the contents can be refilled more easily.
Further, when the body part is pressed with a finger hung on the recess, the pressing force acts directly on the nozzle part, so that the nozzle part can be opened reliably.

In the bag-like container of the present invention, the distance from the top seal portion provided above the trunk portion to the branch line is set to be within 10 mm at least in the central portion.
If the bag-like container is configured in this way, when the contents are moved from the body part to the nozzle part, the swelling above the branch line can be suppressed. In other words, when the upper part of the branch line swells, a force acts in the direction of closing the nozzle part. Therefore, by suppressing the bulge above the branch line, it is possible to prevent the nozzle part from being blocked and improve the content dispensing performance. it can.

In the bag-like container of the present invention, the seal width on both sides of the top seal portion is 20 mm or more.
If the bag-like container is configured in this way, the rigidity of both sides of the top seal portion is improved, so that the bag-like container can be reliably lifted with the fingers hung on the recesses.

Moreover, the bag-shaped container of this invention is set as the structure which formed the mountain fold line in alignment with the center of the said nozzle part in the either one or both of the front and back of the said nozzle part.
If the bag-like container is configured in this way, it is possible to promote the expansion of the nozzle portion and stably dispense the contents. Moreover, a required nozzle opening area can be ensured and the content can be quickly poured out.

Moreover, the bag-shaped container of this invention is set as the structure which can adjust the up-and-down angle of the said nozzle part with respect to the said trunk | drum.
If the bag-like container is configured in this way, not only the nozzle part can be easily inserted into the bottle container when the contents are refilled, but also the angle of the nozzle part can be kept constant regardless of the inclination of the trunk part. it can.

As described above, according to the present invention, since the bag-like container can be stably supported by placing fingers on the concave portions on both sides, the bottle is not spilled when the contents are refilled. Can be refilled into a container.
Moreover, since the nozzle part can be expanded by pressing the body part from both sides with a finger hung on the recess, the inner surface of the nozzle part is prevented from sticking and the contents are stably poured out. It becomes possible.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In addition, there is no restriction | limiting in particular as a material of the soft packaging material used for the bag-shaped container of this invention. Examples of the resin material suitable for constituting the soft packaging material include crystalline polypropylene, crystalline propylene-ethylene copolymer, crystalline polybutene-1, crystalline poly-4-methylpentene-1, low-, and medium- Or polyolefins such as high density polyethylene, ethylene-vinyl acetate copolymer (EVA), ethylene-ethyl acrylate copolymer (EEA), ion-crosslinked olefin copolymer (ionomer); polystyrene, styrene-butadiene copolymer Aromatic vinyl copolymers such as polymers; halogenated vinyl polymers such as polyvinyl chloride and vinylidene chloride resins; nitrile polymers such as acrylonitrile-styrene copolymers, acrylonitrile-styrene-butadiene copolymers; nylon 6, Polyamide such as nylon 66, para or metaxylylene adipamide S, polyethylene terephthalate, polyesters polytetramethylene terephthalate; various polycarbonates; may be mentioned thermoplastic resins such as polyacetal such as polyoxymethylene. Soft wrapping materials made of these materials are used after being unstretched, uniaxially stretched, or biaxially stretched.

  Furthermore, the soft wrapping material used in the bag-like container of the present invention can be constituted by a single layer of these soft wrapping materials or a laminate of two or more kinds, and a kind of these soft wrapping materials. Alternatively, two or more types and a metal foil such as aluminum, a vapor deposition film of metal or metal oxide, paper, cellophane, or the like can be bonded together. As a preferred soft packaging material, for example, a stretched nylon film as an outer layer, a low-density polyethylene, a two-layer structure having a polyolefin film such as polypropylene as an inner layer, a stretched polyester film as an outer layer, and a two-layer structure having a polyolefin film as an inner layer, In addition, among these, a film having a three-layer structure in which a metal foil such as aluminum is laminated between outer layer films, etc., and in the production of these laminated films, an adhesive agent and an anchor agent are interposed in each layer as necessary. It can also be made.

  The layer structure of the soft packaging material is selected according to the properties of the contents to be filled in the bag-like container. For example, when a low cost is required like a bag-like container for a refill detergent, When a laminated film having a layer structure is used and storage stability is required like a seasoning bag-like container, a laminated film having a three-layer structure or more including an aluminum foil may be used.

[First embodiment]
First, a first embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a front view of a bag-like container showing a state where the nozzle part is directed downward, and FIG. 2 is a front view of the bag-like container showing a state where the nozzle part is turned upward.

As shown in these drawings, the bag-like container 10 includes a top seal 13, a side seal 14, a bottom seal 15, etc. on the front and back soft packaging materials forming the body portion 11 and the soft packaging material forming the bottom portion 12. It is formed by applying an edge seal (heat seal).
The soft wrapping material forming the bottom portion 12 is sandwiched between the lower end portions of the trunk portion 11 while being folded in an inverted V shape, and is thermally welded to the trunk portion 11 by the side seal 14 and the bottom seal 15. When the body portion 11 is filled with contents such as detergent, the folded bottom portion 12 expands, and the bag-like container 10 can be self-supporting.

The bag-like container 10 includes a nozzle portion 16 that projects in a branched shape from at least one of the front and back surfaces of the body portion 11 (the front surface in the case of the present embodiment). Such a nozzle portion 16 is easily formed by, for example, forming a bent portion protruding outward on a soft packaging material on either the front or back side that forms the body portion 11 and heat-sealing both sides thereof. can do.
The nozzle portion 16 of the present embodiment is formed so that the width becomes narrower toward the tip end side, and the content is poured out from the center portion of the tip end. The tip portion 17 of the nozzle portion 16 can be cut along a cut line 18, and when the tip portion 17 is cut, a spout 19 is formed and the contents can be poured out.

In order to refill the contents of the bag-like container 10 into a bottle container or the like, first, the tip portion 17 of the nozzle portion 16 is cut along the cut line 18.
Next, the bag-like container 10 is held by hand, and the nozzle part 16 facing downward is inserted into the mouth part of the bottle container. At this time, since the bag-like container 10 does not need to be greatly inclined, the contents do not flow out. Further, the bottle container may be left without being held by hand.
Next, the bag-like container 10 is tilted to start dispensing the contents. After that, the inclination of the bag-like container 10 is gradually increased to increase the amount of contents to be poured out. When the contents in the bag-like container 10 are low, the bag-like container 10 is inverted and the contents in the bag-like container 10 are poured out without waste.

  In other words, according to the bag-like container 10 having the branched nozzle part 16, first, the nozzle part 16 is inserted into the mouth of the bottle container, and then the bag-like container 10 is tilted to start dispensing the contents. This reduces the possibility of spilling the contents when refilling the contents. In addition, since it is not necessary to tilt the bottle container, the refilling operation can be performed with one hand while the bottle container is placed.

Next, the characteristic part of the present invention in the bag-like container 10 will be described.
FIG. 3 is a perspective view showing the bag-like container in a self-standing state, FIG. 4 is a perspective view showing the bag-like container held by hand, and FIG. 5 is a side view showing the bag-like container in a self-standing state.
As shown in FIGS. 1 to 4, the bag-like container 10 includes concave portions 20 on both side portions (side seals 14) of the body portion 11. The shape of the recess 20 is not particularly limited as long as the recess 20 has a size to which a finger can be hung and is formed below the branch line 21 of the nozzle portion 16. The distance L (see FIGS. 1 and 2) from the branch line 21 to the recess 20 is preferably 3 mm to 40 mm.

  When the bag-like container 10 is configured in this manner, as shown in FIG. 4, it is possible to stably support the bag-like container 10 by placing fingers on the concave portions 20 on both sides. When refilling, etc., it can prevent that the nozzle part 16 remove | deviates from the opening | mouth part of a bottle container. In particular, when the distance L from the branch line 21 to the concave portion 20 is 3 mm to 40 mm, the bag-like container 10 can be supported in the vicinity of the nozzle portion 16, so that the position of the nozzle portion 16 is stable and the contents It becomes easier to refill.

Further, when the body portion 11 is pressed from both sides with a finger hung on the concave portion 20, the pressing force acts in a direction to expand the nozzle portion 16, so that the inner surface of the nozzle portion 16 is prevented from being in close contact with the contents. Can be stably dispensed. In particular, when the distance L from the branch line 21 to the recess 20 is set to 3 mm to 40 mm, the pressing force acts directly on the nozzle 16 when the body 11 is pressed with a finger hung on the recess 20. The nozzle part 16 can be opened reliably.
Further, when the bag-like container 10 is lifted by placing a finger on the recess 20, the load of the contents acts in the direction of expanding the nozzle portion 16, so that the effect of preventing the adhesion of the nozzle portion 16 can be further enhanced.

  The distance M from the top seal 13 to the branch line 21 is preferably within 10 mm at least in the central portion. This is because when the distance M from the top seal 13 to the branch line 21 (see FIGS. 1 and 2) exceeds 10 mm, the upper part of the branch line 21 swells greatly when the contents are moved from the body part 11 to the nozzle part 16. This is because a force in the direction of closing the nozzle portion 16 acts. If the distance M from the top seal 13 to the branch line 21 is within 10 mm as in the present embodiment, the upper bulge of the branch line 21 can be suppressed, so that the nozzle portion 16 is prevented from being blocked and the contents can be stabilized. It becomes possible to dispense.

  Moreover, it is preferable to form a mountain fold line 22 along the center of the nozzle portion 16 on either or both of the front and back sides of the nozzle portion 16. The mountain fold line 22 promotes the expansion of the nozzle portion 16, and thus has an effect of stabilizing the content dispensing. Further, when the body part 11 is pressed from both sides with the fingers hung on the recess 20, the opening shape of the spout 19 becomes almost square, so that the opening area can be increased and the contents can be quickly poured out. Become.

Further, as shown in FIG. 5, the nozzle portion 16 preferably has an adjustable vertical angle θ with respect to the body portion 11. If the vertical angle θ of the nozzle portion 16 is adjustable, not only the nozzle portion 16 can be easily inserted into the bottle container when the contents are refilled, but also the angle of the nozzle portion 16 can be adjusted regardless of the inclination of the body portion 11. It becomes possible to keep it constant.
The angle adjustment of the nozzle portion 16 is performed by using the flexibility of the bag-like container and picking up and moving the nozzle portion 16 up and down, but can also be performed by adjusting the pressing force of the finger on the recess 20. When the pressure is increased, the nozzle portion 16 rotates upward.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIG. However, about the structure which is common in 1st embodiment, the code | symbol same as 1st embodiment is attached | subjected and description of 1st embodiment is used.
FIG. 6 is a front view of the bag-like container according to the second embodiment.
As shown in this figure, the bag-like container 10 of the second embodiment is different from the first embodiment in the shape of the top seal 13. Specifically, the seal width N on both sides of the top seal 13 is wider than that of the first embodiment. The seal width N is preferably 20 mm or more. In this way, the rigidity of both side portions of the top seal 13 is improved, so that even when the contents are heavy, the bag-like container 10 can be reliably lifted with the fingers hung on the recess 20.

Needless to say, the present invention is not limited to the embodiment. For example, in the said embodiment, although the spout is formed in the front-end | tip center part of a nozzle part, you may form in the position shifted | deviated from the front-end | tip center part of a nozzle part.
Further, the shape and dimensions of the nozzle portion can be appropriately changed according to the properties of the contents to be filled, the dimensions of the bag-like container, and the like.

  The present invention can be applied to a bag-like container filled with contents such as foods, beverages, cosmetics, and detergents. In particular, it is useful in a bag-like container filled with the contents for refilling.
