Description

  The present invention relates to a pouch container provided with a pouring part for pouring a filling material into a pouch formed in a bag shape by heat-sealing a flexible film.

Conventionally, as a soft packaging container, a side gusset piece is interposed between both sides of a front piece and a back piece made of a flexible film, and the upper side, lower side, and both sides of the front and back piece are heat-sealed by a predetermined width. A pouch container including a pouch formed into a bag shape by doing so and a spout attached to the upper side of the pouch is known.
Such pouch containers are used not only for filling beverages such as sports drinks and foods such as ice cream and jelly, but also for medical applications.

  Pouch containers for medical use are filled with liquid foods such as enteral nutrients (nutrients for PEG), dietary supplements containing vitamins, and jelly for hydration.

By the way, since these fluid foods have comparatively high viscosity, it may be difficult to pour out from the inside of the pouch.
Therefore, in order to squeeze out the filling material filled in the pouch without leaving it, a pair of arm-shaped tightening portions, a hinge portion connecting one end portion thereof, and an openable / closable portion provided at the other end portion are provided. A squeezing tool having a locking portion is known (Patent Document 1).
The squeezing tool disclosed in Patent Document 1 is attached to a pouch by expanding a pair of tightening portions via a hinge portion, sandwiching the pouch therebetween, and fixing the tightening portion with a locking portion. Then, the filler in the pouch can be squeezed out by sliding the attached squeezing tool toward the opening side of the pouch.
However, such a squeezing tool has a relatively complicated structure, and the hinge part may break during use several times. The squeezing tool is a type that slides to squeeze out the filling material, but it is difficult to slide the squeezing tool sandwiched between the pouches against the pouch itself.

On the other hand, there is also known a squeezing tool having a shaft having a slit-like opening that can be inserted into the end of the tube container, and a handle connected to the end of the shaft (Patent Document 2 [0022]). And FIG.
By inserting the end of the tube container into the slit-shaped opening of the shaft of the squeezing tool and rotating the squeezing tool, the tube container can be wound around the shaft and the filler in the tube container can be squeezed out. This squeezing tool has a relatively simple structure, and further, since the filling material is squeezed out by winding the tube container, the squeezing action itself can be easily performed.
JP 2001-139070 A JP 2004-210323 A

The squeezing tool having the slit portion formed on the shaft as described above can be used for squeezing the filling material of the pouch container, and can be used for squeezing the liquid food from the pouch container in an actual medical site or the like. .
Specifically, by inserting the lower side portion of the pouch container into the slit portion of the squeezing tool shaft, rotating the squeezing tool and winding the pouch around the shaft, the liquid food is removed from the spout formed on the upper side portion of the pouch. It can be squeezed out.

  However, since the pouch is formed of a relatively rigid flexible film and is filled with a filling, the lower side of the pouch container is inserted into the slit of the squeezing tool. When winding, the lower side part of the pouch container is easily detached from the slit part, and the filling material may not be easily squeezed out.

  An object of the present invention is a pouch container in which a squeezing tool having a slit formed on a shaft is attached to a pouch, and the pouch is wound around the squeezing tool to squeeze out the filling material. Is to improve the pouch container so that it does not easily disengage.

  The pouch container of the present invention has at least a front surface piece and a back surface piece made of a flexible film, and is formed into a bag shape by heat-sealing the upper side portion, the lower side portion, and both side portions. An extending piece that is inserted into the slit portion of the shaft of the squeezing tool and locked to the shaft at the edge of the lower side portion of the pouch. Is extended.

  In the pouch container of the present invention, an extending piece is extended to the edge of the lower side portion of the pouch. By inserting this extending piece into a slit formed on the shaft of the squeezing tool, the extending piece is locked to the shaft of the squeezing tool. Therefore, when the pouch is wound up by rotating the squeezing tool, the squeezing tool is not easily detached from the pouch, and the filling material can be squeezed out easily.

  In a preferred pouch container of the present invention, the extending piece has a cylindrical portion that extends substantially parallel to the lower side portion of the pouch.

The preferable pouch container of the present invention can easily squeeze the filling by using, for example, a squeezing tool having a shaft that is divided into a plurality of rod-shaped portions at the slit portion.
That is, by inserting the rod-shaped portion of the shaft of the squeezing tool into the cylindrical portion of the extending piece of the pouch container, a part of the extending piece is locked to the shaft of the squeezing tool. Therefore, when the pouch is wound up by rotating the squeezing tool, the squeezing tool is not easily detached from the pouch, and the filling material can be squeezed out easily.

  In another preferable pouch container of the present invention, the extending piece includes a narrow portion extending from an end edge of the lower side portion of the pouch, and a wide portion extending from the narrow portion.

The other preferable pouch container of the present invention can squeeze the filling easily by using, for example, a squeezing tool in which a slit portion is formed in the middle of the longitudinal direction of the shaft.
That is, by fitting the slit portion of the squeezing tool into the narrow portion of the extending piece of the pouch container, the slit portion of the squeezing tool is locked to the wide portion of the extending piece. Therefore, when the pouch is wound up by rotating the squeezing tool, the squeezing tool is not easily detached from the pouch, and the filling material can be squeezed out easily.

  In the pouch container of the present invention, the squeezing tool having a slit formed on the shaft can be locked to the extended piece of the pouch. In the pouch container of the present invention, the squeezing tool attached to the extending piece is not easily detached from the pouch, and the filling material in the pouch can be squeezed easily by rotating the squeezing tool.

Hereinafter, the present invention will be specifically described with reference to the drawings.
(First embodiment)
1 to 3, reference numeral 1 denotes a pouch 2 formed in a bag shape by heat-sealing a peripheral portion of a flexible film, and a pouring portion 3 provided on the pouch 2. , Shows a pouch container. As the extraction | pouring part 3, the spout 3 is mentioned, for example.

The pouch 2 has at least a front surface piece 4 and a back surface piece 5.
Further, an extending piece 7 inserted into the slit portion of the shaft of the squeezing tool and locked to the shaft is extended at the edge of the lower side portion 22 of the pouch 2.

Specifically, the pouch 2 has four surfaces: a front surface piece 4, a back surface piece 5, and both side surface gusset pieces 6 and 6 interposed between the front and back surface pieces 4 and 5.
The front and back pieces 4 and 5 and the both side gusset pieces 6 and 6 are made of a flexible film having a sealant layer as an innermost layer.

The flexible films constituting the front and back pieces 4 and 5 and the side gusset pieces 6 include, for example, a sealant layer for heat-sealing in order from the inside to the outside, and the strength of the bag (bending resistance, pin resistance) A laminated film having a base material layer for retaining a hole property, a barrier layer for imparting a gas barrier property or a light-shielding property, and an outer surface layer for imparting surface friction, heat resistance, etc. It can be illustrated.
The thickness of the flexible film is not particularly limited, but is preferably 60 μm to 150 μm because a certain degree of rigidity is required.

The front and back surface pieces 4 and 5 are formed, for example, in a front hexagonal shape in which both lower sides of a rectangle are cut obliquely. Accordingly, the edges of the upper side portion 21 and the lower side portion 22 of the front and back pieces 4 and 5 are formed in a substantially parallel straight line, and the edges of the side portions 23 of the front and back pieces 4 and 5 are substantially rectangular. It is formed in a shape.
Both side gusset pieces 6 and 6 are formed in a substantially pentagonal shape in front. The edge of the upper side portion of the side gusset piece 6 is formed in a straight line along the edge of the upper side portion 21 of the front and back surface pieces 4, 5. 5 is formed in a substantially square shape along the edge shape of the side part 23.

The side gusset pieces 6 are folded in two on both sides of the front and back pieces 4 and 5, and both side portions 23 of the front and back pieces 4 and 5 and both side portions of the side gusset pieces 6 and 6 are heat-sealed. At the same time, the upper sides of the side gusset pieces 6, 6 interposed on both sides of the upper sides 21 of the front and back pieces 4, 5 and the both sides of the upper sides 21 of the front and back pieces 4, 5 are thermally attached.
Further, the side gusset pieces 6 and 6 are not interposed in the lower side portions 22 of the front and back surface pieces 4 and 5, and the lower side portion 22 of the surface piece 4 and the lower side portion 22 of the back surface piece 5 are directly heat-sealed. Yes.
Further, the spout 3 is sandwiched between the center portions of the upper sides 21 of the front and back pieces 4, 5, and the upper side portion 21 of the front piece 4 is heat-sealed to one surface of the spout 3. 21 is heat-sealed to the other surface of the spout 3.
Thus, with the side gusset pieces 6 and 6 and the spout 3 interposed at predetermined positions, the upper side portion 21, the lower side portion 22, and the both side portions 23 of the front and rear surface pieces 4 and 5 are thermally fused to form a bag shape. Pouch 2 is formed.
The heat-sealing widths of the upper side part 21, the lower side part 22 and the both side parts 23 of the front and back pieces 4 and 5 are not particularly limited, but are usually about 3 mm to 10 mm.
The upper side part 21, the lower side part 22, and both side parts 23 of the front and back pieces 4, 5 correspond to the upper side part 21, lower side part 22, and both side parts 23 of the pouch 2.

  The pouch 2 is filled with a desired filling. The filling is not particularly limited, and examples thereof include beverages, foods such as ice cream and jelly, and fluid foods such as enteral nutrients. Among them, it is effective to apply the present invention to a pouch 2 filled with a liquid food having a relatively high viscosity, for example, a liquid food such as a nutritional supplement containing an enteral nutrient or vitamin.

The pouch 2 shown above is a so-called side pouch with a side gusset in which a bottom surface is not formed after filling with a filling material, and is conventionally known.
As described below, the feature of the present invention is that the extending piece 7 for attaching to the squeezing tool is extended from the lower side portion 22 of the pouch 2, and the pouch 2 itself has the structure shown above. It is not limited to this, A conventionally well-known various structure is employable.
For example, the pouch according to the present invention may be a so-called standing pouch in which a bottom surface is formed by bending a lower region of a front piece and / or a back piece after filling with a filling. The pouch of the present invention may be a standing pouch composed of a front piece, a back piece, and a bottom piece. The pouch of the present invention may be a so-called flat pouch composed of a rectangular surface piece and a back piece (see FIG. 7 for a rectangular surface piece and a back piece). Further, the pouch of the present invention may be composed of a front surface piece, a back surface piece, and one side gusset piece 6.

Moreover, although the spout 3 is used for the pouch container 1 shown above as a pouring part, the pouring part can also be formed without using the spout 3. For example, the pouch container 1 in which insertion holes (pouring parts) are formed in the upper sides 21 of the front and back pieces 4 and 5 may be used. The pouch container 1 can pour out the filling in the pouch 2 by inserting a separate tube into the insertion hole.
The spout 3 is a pouring mouth member made of a synthetic resin molded product. The spout 3 normally has a tube portion that communicates with the inside of the pouch 2 and protrudes to the outside of the pouch 2, and a cap portion that closes the opening of the tube portion. For example, when liquid food is filled in the pouch 2, the cap portion of the spout 3 is removed, and a tube is externally attached to the tube portion protruding from the pouch 2, so that enteral nutrition is provided via the tube. Liquid foods such as drugs and dietary supplements can be administered to patients.

Next, the extension piece 7 will be described.
The extending piece 7 is a portion that extends outward (downward) from the edge of the lower side 22 of the pouch 2. The extending piece 7 is made of a flexible film.
The extension piece 7 is formed of a flexible film constituting the front and back surface pieces 4 and 5. However, the extension piece 7 is formed of a separate flexible film different from the films constituting the front and back pieces 4 and 5, and the extension piece 7 is bonded to the lower side portion 22 of the pouch 2, thereby extending the extension piece 7. The piece 7 may be extended from the lower side 22 of the pouch 2.

The extending piece 7 has a cylindrical portion 71 that extends substantially parallel to the lower side portion 22 of the pouch 2.
Note that “substantially parallel” includes a range in which the angle formed by the extending direction of the lower side portion 22 and the extending direction of the cylindrical portion 71 is 0 ° ± 10 °.
The cylindrical portion 71 is open on both sides thereof (both sides in the direction in which the cylindrical portion 71 extends). As will be described later, since one rod-like portion of the squeezing tool is inserted into the tubular portion 71, the tubular portion 71 is not limited to one having openings formed on both sides. As shown in FIGS. 7 and 8, the cylindrical portion 71 may be open on one side and closed on the other side.

  The extension piece 7 is comprised from the two extension films which extended the flexible film which comprises the surface piece 4 and the back surface piece 5, respectively downward, for example. The lower ends of the two extended films are heat-sealed substantially parallel to the lower side 22 of the pouch 2. By heat-sealing the upper and lower ends of the two extended films (the heat-sealing of the upper ends of the two extended films is also used as the lower side 22 of the heat-sealed pouch 2. The two extended films between the upper and lower ends heat-sealed are not bonded. This non-bonded portion is usually flat, but becomes cylindrical by separating the two extended films. This non-bonded portion becomes the cylindrical portion 71 of the extending piece 7.

  As will be described later, one rod-like portion of the first squeezing tool is inserted into the tubular portion 71. Therefore, the opening area of the cylindrical part 71 should just be formed in the magnitude | size which can insert said one rod-shaped part, and can be suitably set according to the extraction tool to be used. Usually, the opening area of the cylindrical part 71 is 3 mm to 15 mm in diameter, preferably 5 mm to 10 mm in diameter, based on a state in which the cylindrical part 71 is opened in a substantially circular shape.

  The width of the tubular portion 71 (the length in the extending direction of the tubular portion 71) is not particularly limited. However, if the width is too short, it is difficult to start winding the pouch 2 with the first squeezing tool 9. The lower limit of the width of the portion 71 is, for example, 10 mm or more, preferably 20 mm or more. The upper limit of the width of the cylindrical portion 71 is not particularly limited, but if it is longer than the width of the pouch 2 (the width of the front and back surface pieces 4 and 5), film loss occurs in production, and the use of the pouch container 1 Since a hindrance occurs, the width is preferably equal to or smaller than the width of the pouch 2 (see FIG. 7 for the cylindrical portion 71 having substantially the same width as the width of the pouch 2).

As shown in FIG. 4, the pouch container 1 according to the present embodiment has a slit portion 92 formed from the tip portion, and includes a first shaft 91 that is divided into a plurality of rod-like portions by the slit portion 92. A squeezing tool 9 is used. That is, the pouch container 1 and the first squeezing tool 9 of the present embodiment are used as a squeezed set product combining both.
