Description

  The present invention relates to a pouch container for refilling and the like filled with shampoo, cosmetics, detergents, seasonings and the like for replenishing a main body container.

  2. Description of the Related Art Conventionally, refillable pouch containers filled with contents such as shampoo and cosmetics to be replenished in a main body container have been widely used in order to reduce the amount of resources used and reduce the load on the environment. Many of these are formed by laminating two front and back films, and there is an advantage that the amount of resin used as a material is smaller than that of the main body container and the volume when discarded is small because it is folded small.

  When filling the main body container with the contents from these pouch containers, the contents are often poured by inserting the spout formed in the pouch container into the opening of the main body container, but the pouch container is as described above. When formed with a film, the rigidity of the spout is low, so the film is bent and the spout is blocked, making refilling difficult.

In order to solve this problem, a refillable container is known in which a cylindrical tube is inserted and fixed in the spout to increase the rigidity of the spout and secure the opening area of the spout (for example, Patent Document 1). reference.).
Japanese Patent No. 3447752

  Usually, the dimension in the width direction of the tube described above is set based on the inner diameter of the opening of the main body container to be refilled. However, when a cylindrical part is used like the refill container of Patent Document 1, as shown in FIG. 9, the tube 100 and the container are formed in the vicinity of the end portion 100A on the proximal end side of the spout 101 of the tube 100. The distance to the film 102 to be increased. As a result, there is a problem that the content R is less likely to flow smoothly through the spout 101 or a large amount of residual liquid is generated between the end portion 100A of the tube 100 and the film 102.

  This invention is made | formed in view of the said situation, and it aims at providing the pouch container which can pour out the content smoothly.

The present invention is a pouch container in which the peripheral edges of the front member and the back member are integrally joined, and is provided at a part of the peripheral edge for pouring out the contents, and the outer surface is the pouring container. A semi-cylindrical flow path holding member that is fixed to the inner surface of the outlet flow path and reinforces the extraction flow path, and is formed by dividing a cylindrical member having a lumen, and the front member and the At least one portion of the back surface member including the extraction flow path is embossed so as to protrude outward, and the dimension in the width direction of the first end portion in the axial direction of the flow path holding member. Is formed to be smaller than the dimension in the width direction of the second end on the opposite side, and the flow path holding member is arranged such that the first end is positioned on the front end side of the extraction flow path. with and is fixed to the watch overhead stream path, the front member and the rear member Characterized in that is fixed at a site either one of the embossed decorated.

  Note that the “semi-cylindrical shape” refers to a shape in which a tubular member having a circular or polygonal cross section and having a lumen is divided in the axial direction.

In the pouch container of the present invention, when the contents are poured out, the angle formed between the pouring flow path and the continuous main body film is increased, and a gentle flow path for the contents is formed inside.
Moreover, the thickness at the time of pouch container pileup can be suppressed, and efficiency, such as manufacture and filling, can be improved.

  A side surface of the flow path holding member is formed in a trumpet shape so that an angle formed with an axis of the flow path holding member gradually increases from the first end portion toward the second end portion. Also good. In this case, the flow rate of the contents is likely to increase in the extraction channel.

  The pouch container according to the present invention further includes a bottom member that is folded back and forth so that the fold is positioned upward, a front end is joined to the lower end of the front member, and a rear end is joined to the lower end of the back member. You may prepare. In this case, the volume of the pouch container can be increased and self-supporting property can be imparted.

  According to the pouch container of the present invention, it is possible to provide a pouch container capable of smoothly pouring the contents.

Hereinafter, the pouch container 1 of 1st Embodiment of this invention is demonstrated with reference to FIGS. 1-5.
1 is a front view of the pouch container 1, and FIG. 2 is a cross-sectional view taken along line AA of FIG. The pouch container 1 is a container for refilling, and is filled with liquid contents such as shampoo and detergent for replenishing the main body container. The pouch container 1 includes a front member 2, a back member 3 joined to the front member 2, and a bottom member 4 interposed between the front member 2 and the back member 3.

The front member 2, the back member 3, and the bottom member 4 are formed of a sheet-like flexible film (hereinafter referred to as “main body film”) having heat-fusibility.
The main film is made of polyester, nylon, polyethylene terephthalate, or a laminate of these layers and a base layer on which an inorganic compound such as aluminum oxide or silicon oxide is deposited. Is formed. A metal layer such as aluminum may be further laminated as required.

  As shown in FIGS. 1 and 2, the front member 2 and the back member 3 are formed by integrally bonding the heat-fusible layer of the peripheral joint portion 5 by a method such as heat welding. A notch 6 is provided in the upper joint portion 5A of the pouch container 1, and a part of the upper peripheral edge is formed as a pouring channel 7 for pouring out the contents. A ruled line 7B is formed in the vicinity of the tip 7A of the pouring channel 7 along the width direction of the pouring channel 7 by a laser or the like, and the tip 7A is cut off along the ruled line 7B. An opening is formed.

  Embossing E is applied so that the portions of the front member 2 and the rear member 3 that form the pouring channel 7 and the periphery thereof are gently convex toward the outside of the pouch container 1. By this embossing E, the extraction flow path 7 is formed in a substantially tubular shape.

A flow path holding member 8 is fixed to the inner surface of the front member 2 forming the dispensing flow path 7 by means such as heat welding.
3A is a plan view of the flow path holding member 8, and FIG. 3B is a perspective view thereof. As shown in FIGS. 3A and 3B, the flow path holding member 8 is made of a resin such as PP, has a substantially truncated cone shape that is a trapezoidal rotating body, and has a cylindrical shape having a lumen. These members are formed in a substantially half-cylinder shape divided into two equal parts by the rotation shaft.

  The flow path holding member 8 has an outer surface 8A that is fixed to the front member 2 and an inner surface 8B that is a flow path for the contents. As shown in FIG. 1, a part of the outer surface 8A is fixed. The portion 9 is fixed to the front member 2. At this time, the flow path holding member 8 straddles the line L connecting the base ends of the extraction flow path 7 shown in FIG. 1 in order to stabilize the shape of the extraction flow path 7 when the contents are poured out. It is preferable to arrange and fix.

  As shown in FIG. 3A, the dimension d1 in the width direction of the first end 8C in the axial direction of the flow path holding member 8 is larger than the dimension d2 in the width direction of the second end 8D on the opposite side. It is set to be smaller. The first end portion 8C is arranged and fixed so as to be positioned on the tip 7A side of the extraction flow path 7.

  As shown in FIG. 2, the bottom member 4 is interposed between the front member 2 and the rear member 3 in a state where the fold 4A is folded back and forth so that the crease 4A is positioned upward. The end 4C is thermally bonded to the lower end 2A of the front member 2 and the lower end 3A of the back member 3, respectively. When the bottom member 4 is filled with the contents, the fold 4A moves downward due to the weight of the contents, and becomes substantially horizontal. As a result, the volume of the pouch container 1 increases, and at the same time, self-supporting property is imparted.

Operation during use of the pouch container 1 configured as described above will be described.
First, the user cuts and removes the tip 7A of the pouring channel 7 of the pouch container 1 filled with the contents along the ruled line 7B, and opens the pouring channel 7. Then, as shown in FIG. 4, the pouring channel 7 is inserted into the opening C <b> 1 of the main body container C, and the contents of the pouch container 1 are refilled into the main body container C.

  At this time, as shown in a cross section in FIG. 5, the width direction dimension of the second end portion 8D of the flow path holding member 8 is larger than that of the first end portion 8C, and the side surface expands radially outward. Therefore, the distance between the flow path holding member 8 near the second end portion 8D and the main body film of the front member 2 continuous with the extraction flow path 7 becomes shorter than when a right cylindrical member is used. A relatively gentle flow path for the contents R is formed in the container 1. At the same time, the gap formed between the second end 8D and the main body film is also reduced, and the amount of residual liquid in the pouch container 1 is reduced.

  According to the pouch container 1 of the present embodiment, a flow path of contents with a gentle change in angle is formed from the main body film continuous to the discharge flow path 7 to the discharge flow path 7. Therefore, the dynamics of the flow of the contents do not change in the vicinity of the proximal end of the pouring channel 7, and a pouch container in which the contents are smoothly poured out from the pouring channel can be configured.

  Further, even when the pouring channel 7 is pressed against the opening C1 of the main body container C, the channel holding member 8 having rigidity higher than that of the main body film hits the opening C1, so that the pouring channel 7 through which the contents pass is the channel. Blockage is prevented by reinforcement by the holding member 8. Therefore, the cross-sectional area of the extraction channel 7 is sufficiently secured, and the contents for refilling can be smoothly extracted.

The semi-cylindrical channel holding member 8 is fixed to only the front member 2 and disposed on the front member 2 side of the main body film constituting the pouch container 1. Therefore, the back member 3 side of the pouch container 1 is substantially flat, and the thickness when the pouch containers 1 are stacked can be reduced as compared with the case where a cylindrical member is fixed to the pouring channel 7.
For this reason, it is possible to improve transport efficiency, for example, by increasing the number of pouch containers that have been formed into bags and packaging such as cardboard boxes when transporting them to a filling place. Further, when filling the contents, the number of pouch containers 1 set in the magazine of the filling machine can be increased, and productivity can be improved.

Furthermore, since the flow path holding member 8 is formed in a semi-cylindrical shape, the amount of the resin material can be reduced. Furthermore, when fixing to the front member 2, the inner surface 8 </ b> B and the front member 2 can be reliably sandwiched and sufficiently pressed from both sides to be fixed. Therefore, at the time of fixing, the flow path holding member 8 can be fixed more reliably than pressing the opposite outer surface across the inner surface and the fixing surface like a cylindrical member.
In addition, if the flow path holding member is cylindrical, it is not possible to push out the contents having viscosity remaining in the lumen, but the flow path holding member 8 is semi-cylindrical. It is possible to extrude the contents without waste by pushing out from the back member 3 side which is not fixed with a finger or the like.

In addition, since the embossing E is performed so that the front channel member 2 and the rear member 3 that form the pour channel 7 and its periphery swell outward, a sufficient cross-sectional area of the pour channel 7 is ensured. Then, the shape of the outer surface 8A of the semi-cylindrical channel holding member 8 is also well suited, and the channel holding member 8 can be fixed without causing distortion or the like in the extraction channel 7.
In addition, when a flow-path holding member is a semi-cylinder shape, embossing may be provided only in any one of a front surface member or a back surface member.

  In the present embodiment, the example in which the flow path holding member 8 is fixed to the front member 2 has been described, but the flow path holding member 8 may be fixed only to the back member 3 as a matter of course. Moreover, although the thickness of a pouch container increases a little, you may fix so that it may straddle both the front member 2 and the back member 3. FIG.

In the present embodiment, the example in which the flow path holding member is a semi-cylindrical shape has been described, but instead, a semi-cylindrical member having a polygonal cross section may be used.
Furthermore, although the merit at the time of fixation in the semi-cylindrical member described above is reduced, a cylindrical member having a circular or polygonal cross section can also be used as the flow path holding member.

Next, a pouch container according to a second embodiment of the present invention will be described with reference to FIGS. The difference between the pouch container 11 of the present embodiment and the above-described pouch container 1 is the shape of the side surface of the flow path holding member.
In addition, the same code | symbol is attached | subjected to the component which is common in the above-mentioned pouch container 1, and the common description is abbreviate | omitted.

  FIG. 6 is a plan view showing the flow path holding member 12 in the pouch container 11 of the present embodiment. As shown in FIG. 6, the side surfaces constituting the inner surface 12 </ b> A and the outer surface 12 </ b> B of the flow path holding member 12 are formed in a curved surface that is convex toward the radially inner side. The side surface is formed so that the angle formed by the tangent to the axis X of the flow path holding member 12 gradually increases from the first end 12C toward the second end 12D. That is, the flow path holding member 12 of the present embodiment is formed in a so-called trumpet shape and a semi-cylindrical shape as a whole.

FIG. 7 is a cross-sectional view showing a state in which the contents R are refilled from the pouch container 11 to the main body container C. As described above, since the side surface of the flow path holding member 12 is formed in a curved surface shape, the boundary portion between the main body film continuous with the second end portion 12D and the extraction flow path 7 is smoother.
Further, the angle formed by the inner surface 12A with the horizontal plane gradually increases toward the tip 7A side of the pouring channel 7, so that the flow rate of the contents R gradually increases as it proceeds through the pouring channel 7. .

  According to the pouch container 11 of the present embodiment, like the pouch container 1 of the first embodiment, the flow of contents with a gradual change in angle from the main body film continuous to the pouring channel 7 to the pouring channel 7. A path is formed. Furthermore, since the angle formed by the inner surface 12A of the flow path holding member 12 and the horizontal plane increases toward the tip 7A side of the pouring flow path 7, the flow rate of the content R tends to increase, and the content R is poured efficiently. Is issued.

Further, since the side surface of the flow path holding member 12 is formed in a so-called trumpet shape, the dimension in the width direction increases linearly toward the second end portion 8D as in the flow path holding member 8 of the first embodiment. Compared with the process, a region having a dimension substantially the same as the dimension in the width direction of the first end portion 12C is continuous over a certain length, and the first end portion 12C side has a narrower shape. .
Accordingly, a pouch container that can be more easily inserted into the opening of the main body container and can be easily refilled without reducing the flow rate of the contents even if the width direction dimension at the first end is the same. Can do.

  In the present embodiment, the example in which the flow path holding member 12 has a semi-cylindrical shape has been described, but instead, a trumpet-shaped and cylindrical flow path holding member may be fixed to the extraction flow path.

  Although the embodiments of the present invention have been described above, the technical scope of the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention. .

For example, in each of the above-described embodiments, the example in which the thickness of the flow path holding member is uniform has been described, but instead of this, the flow path holding member 20 is changed to the second shape as in the modification shown in FIG. It may be formed so that the thickness gradually decreases toward the end portion 20A, and the second end portion 20A may be fixed so as to be positioned on the proximal end side of the extraction channel.
In this way, since there is no step between the second end 20A of the flow path holding member 20 and the continuous main body film, the amount of remaining liquid is further reduced, and the contents are poured out without waste. Can do.

  In the present invention, the bottom member is not essential. Therefore, if it is not necessary to make the pouch container self-supporting or increase the volume, the pouch container may be configured with only the front member and the back member without using the bottom member.

  Further, in each of the above-described embodiments, the example in which the pouch container is a container filled with the contents for refilling has been described, but the application of the present invention is not limited thereto. Therefore, you may use the pouch container itself of this invention as a main body container which can be poured out stably from the extraction flow path.

It is a front view which shows the pouch container of 1st Embodiment of this invention. It is sectional drawing in the AA of FIG. (A) is a top view which shows the flow-path holding member of the pouch container, (b) is the flow-path holding member perspective view.
