Description

  The present invention relates to a composite container with a pouring part in which a sleeve body is sheathed on a pouch with a pouring part.

As containers for filling beverages and the like, bottle-type containers made of polyethylene terephthalate (so-called PET bottles) are frequently used. However, since this bottle-type container occupies a large volume even when the contents such as beverages are not filled, the convenience of storage and transportation is poor.
On the other hand, a pouch bag formed of a synthetic resin film in a bag shape, a pour-out portion attached to the upper end of the pouch bag, and a pouch with a pour-out portion can be folded flat when not in use. Excellent storage and transportation.
However, since the pouch bag is flexible, the self-supporting stability is poor, and further, the pouch bag is deformed when held by hand, so that there is a problem that it is difficult to open the pouring part.

  In view of these points, a container (so-called bag-in-box container) in which a pouch with a pouring part is put in a cardboard box, or a container (patented with a pouch with a pouring part in an outer frame (resin molded product)) Document [0024] and FIG. 5) are known.

  However, since the bag-in-box container uses a cardboard box, it is inferior in water resistance, cannot see through the pouch bag placed inside, and further has a problem that its outer shape is limited to a rectangular parallelepiped. is there.

The container of Patent Document 1 occupies a large volume even when a pouch with a pouring part is not inserted because the outer frame is a resin molded product, and, like the PET bottle, is not convenient for storage and transportation. There is a problem.
Moreover, the container of the said patent document 1 forms the secondary latching | locking part of the extraction | pouring part by the planar view ellipse shape, and makes this secondary latching part latch to an exterior body, and can open | release the pouch idle | swivel at the time of opening. This prevents the pouring part from being opened and closed easily. However, since both the pouring part and the outer frame body are made of a synthetic resin molded product, both are locked unless an outer frame body that can fit the shape of the sub-locking part of one pouring part is molded. Do not (cannot prevent idling). Therefore, an outer frame must be prepared for each shape of the extraction portion, which increases the product cost.

Japanese Patent Laid-Open No. 11-227869

  An object of the present invention is to provide a composite container with a pouring part that is water-resistant and that can easily open and close the pouring part and that can be obtained relatively inexpensively.

  The composite container with a pouring part of the present invention includes a pouch bag formed by heat-sealing a peripheral part of a synthetic resin film with a predetermined width, and a pouring part attached to one end of the pouch bag. And a sleeve body having a cylindrical main body formed of a synthetic resin sheet in a cylindrical shape, and the sleeve body includes an insertion / removable insertion portion of the pouch with the extraction portion A hole portion and an engagement hole portion capable of engaging and disengaging a part of the peripheral edge portion of the pouch bag; and inserting the pouring portion into the insertion hole portion and inserting the peripheral portion into the engagement hole portion. The sleeve body is externally attached to the pouch with the extraction portion.

Since the pouch bag and the cylinder main body are made of a synthetic resin, the composite container with a pour-out part has high water resistance, and does not cause trouble even if it is put in and out of the refrigerator or filled with a cold beverage to cause condensation.
Further, in the composite container with the pour-out portion, the sleeve body is externally mounted on the pouch with the pour-out portion in a state in which a part of the peripheral portion of the pouch bag is engaged in the engagement hole portion of the sleeve body. When holding the outer surface of the sleeve body by hand and opening the pouring part, a rotational force is applied to the pouch with the pouring part, but when the rotational force is applied, the opening edge of the engaging hole part of the sleeve body is applied. Since a part of the peripheral edge of the pouch bag is hit, the pouch with the pouring part is difficult to idle. For this reason, a pouring part can be opened and closed easily.
Moreover, the peripheral part of the pouch bag is flexible. For this reason, even if the shape of a part of the peripheral edge portion does not match the opening shape of the engaging hole portion, it can be engaged with the engaging hole portion while deforming a part of the peripheral edge portion. Therefore, it is not necessary to form the shape and size of a part of the peripheral portion of the pouch bag substantially the same as the opening shape of the engaging hole portion, and various types of pouches with a pouring portion can be formed using one type of sleeve body. It is possible to obtain a composite container with a large number of extraction parts by packaging. Therefore, a composite container with a pouring part can be produced at a relatively low cost.

  In a preferable composite container with a pouring part of the present invention, the cylinder body part is formed in a substantially straight cylinder shape having openings above and below the tube body part, and crosses the opening above the cylinder body part. An installation surface portion is provided, and the insertion hole portion is formed in the surface of the installation surface portion. One end edge of the installation surface portion and the other end edge facing the insertion surface portion are the first of the cylinder main body portion. The engaging hole is formed between the upper edge and the second upper edge opposite to the upper edge and between the one side edge of the installation surface portion and the third upper edge of the tube main body portion.

The preferable composite container with a pouring part is a substantially straight barrel-shaped cylinder body having a lower opening, so that the lower opening is fitted from the upper side of the pouch with the pouring part, The sleeve body can be packaged on a pouch with a pouring part.
Further, since the installation surface portion is provided so as to cross the opening above the cylinder body portion, when the sleeve body is externally mounted on the pouch with the extraction portion, the upper portion of the pouch with the extraction portion is covered by the installation surface portion. In addition, it is possible to prevent the sleeve body from falling off from the lower side of the pouch with the extraction portion.

  Further, in the composite container with a more preferred dispensing portion of the present invention, the pouch bag is composed of a surface piece and a back piece made of a synthetic resin film, and an upper edge portion of the surface piece and the back piece made of a synthetic resin film. An upper surface piece having a peripheral edge portion thermally bonded to the upper surface piece, and the pouring portion is attached to a surface of the upper surface piece. The upper surface is engaged with the engagement hole in a state where the upper surface is substantially orthogonal to the vertical direction of the cylinder body.

  The first fused portion is a portion where the peripheral edge portion of the upper surface piece and the upper edge portion of the front surface piece or the back surface piece are thermally fused (that is, a portion where two synthetic resin films are thermally fused). Relatively high rigidity. In the preferable composite container with the pouring portion, the first fusion portion is engaged with the engagement hole portion in a state in which the upper surface of the highly rigid first fusion portion is substantially orthogonal to the vertical direction of the cylinder body portion. Therefore, the upper surface of the first fusion part extends in the rotation direction of the extraction part. For this reason, when the outer surface of the sleeve body is held by hand and the pouring portion is opened, the first fused portion that hits the opening edge of the engaging hole portion is hardly distorted. Therefore, the 1st fusion part inserted in the engaging hole part cannot be easily removed from the engaging hole part at the time of opening, and can effectively prevent the pouch with the pouring part from spinning around.

Since the composite container with a pouring part of the present invention has water resistance, the strength does not decrease even if dew condensation occurs.
Furthermore, the composite container with a pouring part of the present invention can easily open and close the pouring part without opening the pouch with the pouring part when the pouring part is opened.
Moreover, the composite container with the extraction | pouring part of this invention can be manufactured comparatively cheaply.

The perspective view of the composite container with the extraction part which concerns on one embodiment. The thin ink-painted portion of the pouch bag represents a fused portion where the film is thermally fused (the same applies to FIGS. 6 to 10).

Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.
However, in FIG.10 and FIG.11, it is the state which is not filled with the content, Comprising: The pouch with the extraction | pouring part of the state folded into flat shape is represented. The pouch with a pouring part in other figures is shown in a state of being filled with contents. Hereinafter, the state in which the content is not filled may be referred to as “unfilled”, and the state in which the content is filled may be referred to as “filled”.
In addition, with respect to the pouch bags shown in FIGS. 1, 3, 5, 6, 7, 8, 11, and 18, when the periphery of the pouch bag is viewed, the periphery is a single bag. Although it is represented by one layer as it is composed of the film, the periphery represented by the one layer is actually two films (the top piece, the top piece, the back piece and the bottom piece). Note that the two pieces overlap. That is, it should be noted that the peripheral edge represented by one layer is represented by one layer in consideration of the fact that it is difficult to see where the two layers should be superimposed.

In FIG. 1 to FIG. 6, reference numeral 1 denotes a composite container with a pouring part including a pouch 2 with a pouring part and a sleeve body 3 sheathed on the pouch 2.
The pouch 2 with a pour-out part includes a pouch bag 4 formed by heat-sealing a peripheral part of a flexible synthetic resin film with a predetermined width, and a pour-out part 5 attached to one end of the pouch bag 4. Have.

The peripheral portion of the pouch bag 4 is a portion where at least two synthetic resin films are heat-sealed by a predetermined width. Since this part is a part where two films are heat-sealed, the rigidity is higher than that of the synthetic resin film alone. Hereinafter, the heat-sealed portion may be referred to as a “fused portion”.
The sleeve body 3 includes a tube main body portion 6 in which a synthetic resin sheet is formed in a cylindrical shape, and a construction surface portion 7 provided so as to cross the opening 65 above the tube main body portion 6. The cylinder body 6 has openings (upper opening 65 and lower opening 66) above and below, respectively, and the inner circumferential length of the lower opening 66 is the outer circumference of the filled pouch bag 4. It is almost the same as the length.

  The synthetic resin film forming the pouch bag 4 means a sheet material that is more flexible than the synthetic resin sheet forming the sleeve body 3. For example, when both are formed of the same synthetic resin material, the synthetic resin film is a single wafer whose thickness is thinner than that of the synthetic resin sheet, whereas when both are the same thickness The synthetic resin film is a sheet made of a material having lower rigidity than the synthetic resin sheet.

  The lower opening 66 of the sleeve body 3 is fitted from the upper side of the filled pouch 2 with the pouring portion (the side to which the pouring portion 5 is attached), and the sleeve body 3 is fitted below the pouch 2 with the pouring portion. The sleeve body 3 can be attached to the outside of the pouch 2 with the extraction portion by pushing down to the side (the side facing the extraction portion 5). Thus, the composite container 1 with the pouring part of the present invention can be obtained by a simple operation of fitting the opening 66 below the sleeve body 3 from the upper side of the pouch 2 with the pouring part.

  In this exterior state, the upper portion of the pouch bag 4 (the upper surface piece 41 when the upper surface piece 41 is provided; the upper edge portion of the front and rear surface pieces 42 and 43 when the upper surface piece 41 is not provided) is the installation surface portion. 7 and the body portion of the pouch bag 4 (front and back pieces 42 and 43. When there are side gusset pieces between the front and back pieces 42 and 43, the front and back pieces 42 and 43 and the side gusset pieces) Covered by the cylinder body 6 and further below the pouch bag 4 (bottom piece 44 when the bottom piece 44 is provided, and lower edge portions of the front and back pieces 42 and 43 when the bottom piece 44 is not provided). It is opened by looking through the lower opening 66. Further, the pouring portion 5 (at least the screw cap 51 of the pouring portion 5) protrudes outward from the insertion hole portion 9 of the sleeve body 3, and the peripheral edge of the pouch bag 4 outward from the engaging hole portion 8 of the sleeve body 3. A part of the part is projected.

Specifically, as shown in FIGS. 7 to 11, the pouch bag 4 includes an upper surface piece 41, a front surface piece 42, a back surface piece 43, and a bottom surface piece 44, and the peripheral portions of these surface pieces 41 to 44. Are formed into a bag shape by heat-sealing each other with a predetermined width. Although the width | variety of a melt | fusion part is not specifically limited, Usually, it is about 3 mm-10 mm.
Each of these face pieces 41 to 44 is formed from a synthetic resin film whose inner face has heat-fusibility. As this synthetic resin film, a conventionally known film can be used. For example, in order from the inside to the outside, a sealant layer (for example, polyethylene) for heat-sealing, a base material layer (for example, polyamide) for ensuring the strength of the bag, gas barrier properties and light shielding properties And a laminated resin film having a barrier layer (for example, aluminum vapor deposition) for imparting, and the like, and an outer surface layer (for example, polyethylene terephthalate, etc.) for imparting surface friction, heat resistance, and the like. The thickness of the synthetic resin film is not particularly limited, but is generally 60 μm to 150 μm.

The upper surface piece 41 is formed, for example, in a substantially hexagonal shape in plan view that approximates a spindle shape (see FIG. 10). In addition, in this specification, planar view means the shape which looked at the target object from the normal line direction.
More specifically, the upper surface piece 41 has two opposing edges (first edge 411 and second edge 412, third edge 413 and fourth edge 414, fifth edge 415 and sixth edge 416), respectively. It is a substantially hexagonal shape that is substantially parallel.

The internal angles of the adjacent third edge 413 and the sixth edge 416 and the internal angles of the adjacent fifth edge 415 and the fourth edge 414 are each acute or 90 °, and preferably 45 ° to 90 °, respectively. More preferably, the two interior angles are the same acute angle.
The inner angles of the adjacent first edge 411 and the third edge 413, the inner angles of the adjacent first edge 411 and the fifth edge 415, the inner angles of the adjacent second edge 412 and the sixth edge 416, and the adjacent second edge 412 The fourth edges 414 have obtuse angles, preferably 130 ° to 155 °, and more preferably the four inner angles are the same obtuse angle. However, the connecting corners of the adjacent first edge 411 and third edge 413 (the corners forming the inner corner), the connecting corners of the first edge 411 and the fifth edge 415, and the second edge 412 and the sixth edge 416 As shown in FIG. 10, the connecting corners and the connecting corners of the second edge 412 and the fourth edge 414 are preferably slightly rounded in an arc shape. The four interior angles in are based on a state in which each connection corner is not rounded.

Since the two inner angles and the four inner angles are set to the angles, the upper surface piece 41 has a substantially spindle shape with a long width direction. Therefore, when the sleeve body 3 is fitted from the upper side of the filled pouch 2 with the pouring portion, the region is defined by the third edge 413 and the sixth edge 416 and the fifth edge 415 and the fourth edge 414 are defined. The region to be bent is dragged downward by the sleeve body 3 and is bent downward (bends so as to be in close contact with the fused portions of the front and back surface pieces 42 and 43), and the upper portion of the body of the pouch bag 4 is neatly accommodated in the sleeve body 3. (See FIGS. 1 and 2).
Further, a fused portion corresponding to the first edge 411 (referred to as the first fused portion 411a) and a fused portion corresponding to the second edge 412 (referred to as the second fused portion 412a) are the engagement holes of the sleeve body 3. It enters the portion 8 and protrudes outward from the engaging hole portion 8. At this time, the first fusion part 411a and the second fusion part 412a are hardly bent (although they can be slightly curved in the same direction as the installation surface part 7), the first fusion part 411a and the second fusion part 412a are not bent. Each upper surface of the attachment portion 412a extends so as to be substantially orthogonal to the vertical direction of the cylinder body portion 6 (a direction parallel to a line connecting the center of the upper opening 65 and the center of the lower opening 66). In this state, the sleeve body 3 is engaged with the engagement hole 8.

A pouring part 5 is attached to a substantially central part in the surface of the upper surface piece 41. The pouring part 5 has a spout (not shown) communicating with the inside of the pouch bag 4 and a screw cap 51 attached to the outer wall of the spout by a screw action. By turning the screw cap 51, the spout can be opened and closed.
The screw cap 51 of the dispensing part 5 is rotatable around a line parallel to the vertical direction of the cylinder body 6 of the sleeve body 3. That is, the extraction part 5 is attached so that the screw cap 51 rotates in the circumferential direction of the cylinder main body part 6.

An attachment portion (not shown) is integrally formed below the spout, and the attachment portion is heat-sealed (or bonded using an adhesive or the like) to the upper surface piece 41 to pour out. The part 5 is attached to one end (upper part) of the pouch bag 4.
Further, the lower outer wall of the spout is formed with two stages of locking hooks 52 for locking to the suspension bar of the filling machine. 41 is exposed to the outside. The outer shapes of the screw cap 51 and the locking hook 52 may be substantially the same, or one of them may be larger. In the present embodiment, both external shapes are circular in plan view having substantially the same size.
Although the material of the extraction | pouring part 5 is not specifically limited, The extraction | pouring part 5 is normally formed from a synthetic resin molded product.

The surface piece 42 includes a straight lower edge, straight side edges that are connected to the lower edge substantially at right angles, a first edge 411 and a third edge of the upper face piece 41 that are provided above the both edges. 413 and the upper edge of the shape along the 5th edge 415 are formed in planar view substantially rectangular shape. The back piece 43 has the same shape as the front piece 42.
The bottom piece 44 has a rectangular shape and is folded in half at the center.

In a state where the bottom piece 44 folded on the lower side of the front piece 42 and the back piece 43 is sandwiched, the lower edges of the front piece 42 and the back piece 43 are heat-sealed to the peripheral edge of the bottom piece 44 by a predetermined width, and Both side edges of the piece 42 and the back piece 43 are heat-sealed with a predetermined width. Further, the upper edge portion of the surface piece 42 is heat-sealed with a predetermined width to the first edge portion (the edge portion corresponding to the first edge 411, the same applies hereinafter), the third edge portion, and the fifth edge portion of the upper surface piece 41. And the upper edge part of the back surface piece 43 is heat-sealed by the predetermined width to the 2nd edge part of the upper surface piece 41, the 4th edge part, and the 6th edge part.
In this way, the pouch bag 4 is configured by heat-sealing the peripheral portions of the face pieces 41 to 44 by a predetermined width to form a fusion portion including the first fusion portion 411a and the second fusion portion 412a. ing.
The filled pouch 2 with the pouring portion can be self-supported by placing the lower edge of the front surface piece 42 and the lower edge of the back surface piece 43 on the placement surface (on the plane), but by covering the sleeve body 3, Since the pouch bag 4 is less likely to be deformed and the lower edge of the sleeve body 3 is also in contact with the mounting surface, self-supporting stability comparable to that of a PET bottle can be obtained.

  Note that the pouch bag 4 is not limited to the case where the pouch bag 4 is formed of the four face pieces, and can be appropriately changed. For example, the bottom piece 44 may be omitted, and the lower edge of the front piece 42 and the lower edge of the back piece 43 may be heat-sealed with a predetermined width. A side gusset piece is sandwiched between one side or both sides of the surface piece 42 and the back piece 43, and both side edges of the surface piece 42 and the back piece 43 and both side edges of the side piece are heat-sealed by a predetermined width. (In this case, it becomes a pouch bag having a side gusset). In addition, since the upper surface piece 41 is provided in the above, there is an advantage that the upper portion of the pouch bag 4 is neatly accommodated in the sleeve body 3, but the upper surface piece 41 is omitted and each upper edge of the front surface piece 42 and the rear surface piece 43 is provided. The part may be directly heat-sealed. When the upper surface piece 41 is not provided, the surface piece 42 is sandwiched between the upper edge portion of the front surface piece 42 and the upper edge portion of the back surface piece 43 and the mouth portion of the pouring portion 5 is interposed therebetween. And each upper edge part of the back surface piece 43 is heat-seal | fused.

  The contents filled in the pouch bag 4 are not particularly limited, and examples thereof include liquid foods such as beverages and seasonings, and fluid foods such as enteral nutrients. Since the composite container 1 with the pouring part of the present invention is also excellent in water resistance, there is no problem even if it is filled with a cooled content (such as a beverage).

Next, as shown in FIG. 12 to FIG. 16, the sleeve body 3 includes a cylinder main body portion 6 in which a synthetic resin sheet is formed in a cylindrical shape, and an installation surface portion that is continuously provided on the upper edge of the cylinder main body portion 6. 7.
The sleeve body 3 (the tube main body portion 6 and the installation surface portion 7) is integrally formed from a synthetic resin sheet. The synthetic resin sheet forming the sleeve body 3 is not particularly limited, and conventionally known ones can be used. Examples thereof include polyolefin-based materials such as polypropylene and polyethylene, synthetic resin sheets such as polyethylene terephthalate, and laminated sheets thereof. The synthetic resin sheet may be a transparent sheet or an opaque sheet (for example, printing on a transparent sheet). When it is desired to show the design printed on the pouch bag 4 from the outside of the sleeve body 3, the sleeve body 3 is formed from a transparent sheet.
Although the thickness of the said synthetic resin sheet | seat is not specifically limited, About 0.2 mm-1.0 mm can be illustrated.

  The cylinder body 6 has a cylindrical shape having openings 65 and 66 above and below, respectively. It is preferable that the cylinder body 6 is formed in a substantially straight cylinder shape whose outer shape is substantially the same at any position in the vertical direction. Such a substantially straight cylinder-shaped tube main body 6 can be easily formed using a synthetic resin sheet, and the filled pouch bag 4 fitted therein is in contact with substantially the entire inner surface of the tube main body 6 (the sleeve body 3). ) And the pouch bag 4), the entire volume of the composite container 1 with the pouring portion can be reduced.

  The opening 66 below the cylinder body 6 is designed so that its inner circumference is substantially the same as or slightly longer than the circumference of the filled pouch bag 4. When the lower opening 66 of the cylinder main body 6 is fitted from the upper side of the filled pouch 2 with the pouring portion, the upper portion of the pouch bag 4 is neatly accommodated in the cylinder main body 6 and the pouch bag The front surface piece 42 and the back surface piece 43 are in contact with the inner surface of the cylinder body 6.

  The length of the cylinder body 6 in the vertical direction is not particularly limited as long as it can be externally attached to the whole or a part of the body of the pouch bag 4. In the state where the sleeve body 3 is externally attached to the pouch 2 with the pouring part and the inner surface of the installation surface part 7 is in contact with the upper surface piece 41 of the pouch bag 4, the lower edge of the tube body part 6 and the lower edge of the pouch 2 with the pouring part It is preferable that the length of the tube main body 6 is set so as to substantially match.

The cylinder body 6 may be substantially cylindrical, or may be a polygonal cylinder such as a substantially square cylinder or a substantially hexagonal cylinder (the cylinder body 6 shown in the figure has four crease lines extending in the vertical direction at equal intervals. And has a substantially rectangular tube shape that is bent along the four crease lines). Since the cylinder main body 6 is formed from a synthetic resin sheet, it is slightly rounded by being pushed by the filled pouch bag 4 from the inside. For this reason, there is almost no influence in that the pouch bag 4 is covered from the outside, regardless of whether the cylinder body 6 is substantially cylindrical or polygonal.
However, in the present embodiment in which the installation surface portion 7 is stretched over the first upper edge 61 and the second upper edge 62 of the cylinder main body portion 6, the first upper edge 61 and the second upper edge 62 of the cylinder main body portion 6. Since the construction surface portion 7 or the tube main body portion 6 may be deformed into an indefinite shape when the shape is an arc shape that bulges outward, a polygonal tube shape in which at least the first upper edge 61 and the second upper edge 62 are straight lines (in particular, A substantially cylindrical body body 6 is preferable.

An erection surface portion 7 is connected to the upper edge of the cylinder main body portion 6 so as to cross the upper opening 65. The erection surface portion 7 is a sheet piece having a substantially rectangular shape in plan view, and one end edge thereof and the other end edge facing this are opposed to the first upper edge 61 of the substantially rectangular tubular body 6 and the first upper edge 61 thereof. The two upper edges 62 are connected to each other.
The width (interval from one end edge to the other end edge) of the erection surface portion 7 is the length of the opening 65 above the substantially rectangular tube-shaped tube body portion 6 (when the tube body portion 6 is formed into a substantially rectangular tube shape). , The distance from the first upper edge 61 to the second upper edge 62). Therefore, the construction surface portion 7 is an arcuate surface that swells upward.
The one side edge 71 of the erection surface portion 7 and the other side edge 72 opposite thereto are not connected to the third upper edge 63 and the fourth upper edge 64 opposite thereto, respectively. Therefore, substantially semicircular openings are formed between the one side edge 71 and the third upper edge 63 and between the other side edge 72 and the fourth upper edge 64, respectively. This opening is the engagement hole portion 8 into which a part of the peripheral edge portion of the pouch 2 with the extraction portion is engaged.

Further, an insertion hole portion 9 into which the extraction portion 5 can be inserted and removed is formed in the surface of the installation surface portion 7.
The insertion hole portion 9 is an opening larger than the shape of the screw cap 51 in a plan view so that at least the screw cap 51 of the extraction portion 5 protrudes outside the installation surface portion 7. The planar view shape of the insertion hole 9 is preferably, for example, a circular shape that is slightly larger than the diameter of the screw cap 51. In the present embodiment, the insertion hole portion 9 is an opening larger than the screw cap 51 and the locking hook portion 52 of the extraction portion 5, and therefore, the screw cap 51 and the locking hook portion 52 are inserted into the insertion hole portion. 9 can be inserted and removed freely. The screw cap 51 and the locking hook portion 52 of the pouch 2 with the extraction portion fitted inside the sleeve body 3 protrude outward from the insertion hole portion 9 of the installation surface portion 7.
The insertion hole 9 is an opening larger than at least the screw cap 51, but if it is too large, the inserted pouch 2 with the pouring part may come out of the insertion hole 9. Therefore, the insertion hole portion 9 is formed in such a size that the inner surface of the installation surface portion 7 hits the upper surface piece 41 and the pouch 2 with the extraction portion does not come out.

  The sleeve body 3 can be formed by cutting out (or punching out) a synthetic resin sheet into a predetermined shape, bending or bending the synthetic resin sheet as appropriate, and bonding the adhesive margin portion with an adhesive (or solvent). The illustrated sleeve body 3 is formed by adhering a sheet cut into a predetermined shape at two paste margin portions of the cylinder body 6.

In the composite container 1 with the pouring part, after the contents are filled in the pouch 2 with the pouring part, the sleeve body 3 is fitted from above, and the first fusion part is inserted into the pair of left and right engaging holes 8. It is obtained by engaging 411a and the second fusion part 412a.
Since the peripheral part of the pouch bag 4 is flexible, the shape of a part of the peripheral part (the first fusion part 411a and the second fusion part 412a) and the opening shape of the engaging hole part 8 do not match. Even if it exists, this can be engaged in the engagement hole part 8, deform | transforming a part of peripheral part. Therefore, there is no need to form the shape and size of a part of the peripheral edge of the pouch bag 4 to be substantially the same as the opening shape of the engaging hole portion 8, and various kinds of pouring portions using one type of sleeve body 3. The attached pouch 2 can be packaged. Therefore, the composite container 1 with a pouring part can be produced at a relatively low cost.

The pouch 2 with the pour-out portion, in which the pouch bag 4 and the cylinder main body portion 6 are made of synthetic resin, has higher water resistance than paper, and does not cause any trouble even if condensation occurs.
When opening the pouring part 5 (screw cap 51) of the composite container 1 with the pouring part while holding the outer surface of the sleeve body 3 with one hand, the pouch 2 with the pouring part fitted inside the sleeve body 3 is attached. Although rotational force is applied, a part of the peripheral edge of the pouch bag 4 (the first fusion part 411a and the second fusion part 412a of the upper surface piece 41) hits the opening edge of the engagement hole 8 of the sleeve body 3, The pouch 2 with a protruding portion is difficult to rotate. Therefore, the extraction | pouring part 5 can be opened and closed easily.

  In particular, since the first fused portion 411a and the second fused portion 412a are portions where the synthetic resin film is thermally fused, the rigidity is relatively high. The first fusion part 411a and the second fusion part 412a are engaged with the upper surfaces of the first fusion part 411a and the second fusion part 412a being substantially orthogonal to the vertical direction of the cylinder body 6. Since it is engaged in the hole 8, the first fusion part 411 a is arranged in the rotation direction of the screw cap 51 (the circumferential direction of the cylinder body 6) with a line parallel to the vertical direction of the cylinder body 6 as the rotation axis. And each upper surface of the 2nd melt | fusion part 412a is extended. For this reason, when opening the extraction | pouring part 5 (screw cap 51), the 1st melt | fusion part 411a and the 2nd melt | fusion part 412a which contacted the opening edge of the engagement hole part 8 are hard to be distorted. Therefore, the 1st fusion part 411a and the 2nd fusion part 412a are hard to come off from the engagement hole part 8, and can prevent the idle rotation of the pouch 2 with a pouring part effectively.

Since the lower edge of the pouch 2 with the extraction portion and the lower edge of the sleeve body 3 are in contact with the placement surface, the composite container 1 with the extraction portion has excellent self-standing stability.
Further, by pulling out the sleeve body 3 from the pouch 2 with the extraction portion, it can be separated into the sleeve body 3 and the pouch 2 with the extraction portion, so that separation for recycling can be easily performed.

  Furthermore, as shown in FIG. 17, if a crease line is formed at a predetermined position of the sleeve body 3 made of a synthetic resin sheet, the sleeve body 3 can be folded into a substantially flat shape. By folding the sleeve body 3 in a substantially flat shape as described above, it is possible to save space when the sleeve body 3 is stored and transported. The crease line is formed at a position where the sleeve body 3 can be folded in a substantially flat shape by being bent at the crease line. For example, a pair of left and right folded ruled lines X, X extending in the vertical direction are formed at two locations on the cylinder body 6 facing each other with the center of the opening 66 as a reference, and on the extension line of the pair of folded ruled lines X, X In this case, the sleeve body 3 can be folded into a substantially flat shape by forming the crease lines Y, Y crossing the surface of the installation surface portion 7.

In addition, the composite container 1 with the extraction | pouring part of this invention is not restricted to the said embodiment, It can change variously. Hereinafter, the description is abbreviate | omitted about the structure similar to the said embodiment, and a term and a code | symbol are used.
For example, in the above-described embodiment, the third upper edge 63 and the fourth upper edge 64 of the cylinder main body 6 are linear extending in a direction orthogonal to the vertical direction, but as shown in FIGS. The third upper edge 63 and the fourth upper edge of the part 6 may be formed in an arc shape bulging upward. In particular, it is preferable that the third upper edge 63 and the fourth upper edge of the cylinder main body 6 are formed in an arc shape close to the inner surface of the erection surface portion 7 which is an arcuate surface.
The arc-shaped third upper edge 63 and the fourth upper edge are not connected to the both side edges of the erection surface portion 7, and between the third upper edge 63 and the one side edge 71 of the erection surface portion 7, and the fourth Between the upper edge 64 and the other side edge 72 of the installation surface part 7, an opening (entrance hole part 8) composed of an arcuate thin gap is formed. Since the peripheral edge portion of the pouch bag 4 is thin, it can be engaged with the engagement hole portion 8 formed of such a narrow gap. In addition, the engagement hole portion 8 formed of such a gap is matched with a part of the peripheral portion of the pouch bag 4 (the first fusion portion 411a and the second fusion portion 412a). improves. Therefore, it is possible to effectively prevent the pouch 2 with the pouring portion from spinning around.

  Further, in the above-described embodiment, the sleeve body 3 is provided with the two engaging hole portions 8 and 8, and the engaging hole portions 8 and 8 are provided with the first fusion portion 411 a and the second fusion portion 412 a of the pouch bag 4. However, for example, only the first fusion part 411 a may be engaged in the engagement hole 8. Since the pouch bag 4 is engaged with the engagement hole portion 8 of the sleeve body 3 at least at one place, it is possible to prevent the pouch 2 with the extraction portion from spinning around.

  Further, in the above embodiment, the engaging hole portion 8 is formed between the upper edge of the sleeve body 3 and the erection surface portion 7. For example, the engagement hole portion 8 is formed in a part of the surface of the sleeve body 3 (or the erection surface portion 7). An opening may be formed and used as the engaging hole 8. When the engaging hole portion 8 is formed in the surface of the sleeve body 3 (or the installation surface portion 7) in this way, the peripheral edge portion of the pouch bag 4 so as to correspond to the engaging hole portion 8 when the sleeve body 3 is exteriorized. An extension portion is formed by extending a part of the extension hole portion, and the extension portion is engaged with the engagement hole portion 8.

  Further, in order to bond a part of the inner surface of the sleeve body 3 and a part of the outer surface of the pouch bag 4, an adhesive portion may be partially provided between the sleeve body 3 and the pouch bag 4. As described above, in the composite container 1 with the pouring part of the present invention, a part of the peripheral part of the pouch bag 4 is engaged with the engaging hole part 8 of the sleeve body 3, so that the pouring part 5 is opened. However, when the pouch 2 with the extraction portion is difficult to rotate, the rotation of the pouch 2 with the extraction portion can be reliably prevented by providing the adhesive portion.

The position where the bonding portion is provided is not particularly limited. For example, as shown in FIGS. 20 and 21, the bonding portion 91 is provided between the outer surface of the surface piece 42 of the pouch bag 4 and the inner surface of the tube main body portion 6 of the sleeve body 3. Are provided in a strip shape in the vertical direction. In FIG. 20, the range in which the adhesive portion 91 is provided is represented by shading in order to easily understand the range.
Moreover, the said adhesion part may be provided in the part between the back surface piece 43 and the cylinder main-body part 6, or may be provided in the part between the upper surface piece 41 and the construction surface part 7 (not shown). Further, the adhesive portion is not limited to a belt shape, and may be provided in one or a plurality of dot shapes.
The adhesive part is usually composed of an adhesive or a pressure-sensitive adhesive. It does not specifically limit as an adhesive agent or an adhesive, A heat sensitive adhesive, a solvent-type adhesive, a pressure sensitive adhesive, etc. are mentioned.

Further, a dividing auxiliary line may be provided in the sleeve body 3. This dividing auxiliary line is provided to divide the cylindrical main body portion 6 and / or the installation surface portion 7 which are cylindrical.
Examples of the auxiliary cutting lines include perforations (those in which through holes are formed intermittently), half-cut lines (thickly cut in a V shape in the thickness direction), and the like. The perforation is preferable because the sleeve body 3 can be divided.
Although the number of dividing auxiliary lines may be one, it is preferable that they are a set of two. If it is a set of two auxiliary cutting lines, the belt-like region between the two auxiliary cutting lines can be cut out to easily divide the sleeve body 3.

Although the location where the dividing auxiliary line is provided is not particularly limited, for example, as shown in FIG. 22, a set of dividing auxiliary lines 92 and 92 are provided below the third upper edge 63 of the cylinder main body 6 of the cylinder main body 6. It is provided in the vertical direction over the edge.
Moreover, you may provide a set of division | segmentation auxiliary lines from the 4th upper edge 64 of the cylinder main-body part 6 to the lower edge of the cylinder main-body part 6 (not shown). Furthermore, a dividing auxiliary line may be provided from the third upper edge 63 to the lower edge and from the fourth upper edge 64 to the lower edge of the cylinder body 6 of the cylinder body 6.
Further, as shown in FIG. 23, a set of dividing auxiliary lines 92 and 92 may be provided from one side edge 71 to the other side edge 72 of the installation surface portion 7.

If the above-described dividing auxiliary line 92 is used, a part of the cylinder body 6 can be divided from the upper edge to the lower edge, and / or a part of the installation surface part 7 can be easily extended from one side edge to the other side edge. Can be divided. After the content has been poured out, the sleeve body 3 remains covered on the pouch 2 with the pouring part when the tube body part 6 and / or the installation surface part 7 are cut using the cutting auxiliary wire 92 (that is, Without separating the sleeve body 3 and the pouch 2 with the extraction portion in the state of the composite container 1 with the extraction portion, the whole can be easily crushed into a substantially flat shape. By crushing into a substantially flat shape, the occupied space during disposal or recycling can be reduced.
In addition, when crushing into a substantially flat shape without performing the above-described division, the composite container 1 with the extraction portion is easily returned to the original shape by the restoring force of the sleeve body 3, but the sleeve body 3 is By dividing | segmenting, the return of the composite container 1 with the extraction | pouring part also becomes small.
Furthermore, when an adhesive portion is provided between the sleeve body 3 and the pouch bag 4 as in the above modification, the sleeve body 3 cannot be easily extracted from the pouch 2 with the dispensing portion. Therefore, after pouring the contents, it is considered that this is often crushed in the state of the composite container 1 with the pouring part. Therefore, it is particularly effective to form a dividing auxiliary line when the bonding portion is provided.

  The composite container with a pouring part of the present invention can be used as a container for storing liquid foods such as beverages and seasonings, liquid sanitary products such as shampoos and detergents, fluid foods, and fluid granules.
