Description

  The present invention relates to a pouch container that is filled with a liquid commodity such as shampoo and rinse for refilling a bottle container.

  Liquid products such as shampoos and detergents were sold in the state of being filled in bottle containers, but in recent years, liquid products such as shampoos have been filled into simple pouch containers in order to effectively use bottle containers. Liquid products for refilling are sold.

  Therefore, the consumer first purchases the liquid product filled in the bottle container or the like. However, if the liquid product is used up, the consumer does not purchase a new liquid product filled in the bottle container or the like. Instead, a liquid product for refill, which is the same product filled in a simple pouch container, is purchased, and only the liquid product is refilled into an empty bottle container or the like.

  For example, as a pouch container filled with liquid merchandise, there is one as shown in FIG. As shown in FIGS. 9 and 10, the pouch container 50 includes a pair of front and back exterior sheets 51, 51 in which a protruding piece 51 a that forms a spout portion TMP extends upward, and a pair of front and back exterior sheets 51, 51. Between the protruding piece 51a portion of 51, a top gusset sheet 52 that is folded inward from the top to form a top gusset portion and a pair of front and back exterior sheets 51, 51 are folded inward from the bottom to the bottom gusset. The bottom gusset sheet 53 and the bottom gusset sheet 53 are formed, and the peripheral edges of the top gusset sheet 52 and the bottom gusset sheet 53 are heat-sealed to the exterior sheets 51, 51, and the top gusset sheet 52 and the bottom gusset sheet 53 The outer peripheral sheets 51, 51 that do not overlap with each other are heat-sealed to form a bag It is formed.

  In order to transfer the liquid commodity filled in the pouch container 50 to the bottle container, as shown in FIG. 11, the spout TM is formed by cutting the tip of the spout TMP, and the spout The TM is placed along the mouth of a bottle container or the like, and the filled liquid product is naturally poured from the spout into the mouth of the bottle container.

  However, in the pouch container 50 as described above, the spout TM formed by cutting out the tip of the spout TMP formed by the protruding pieces 51a, 51a of the exterior sheets 51, 51 and the top gusset sheet 52. As shown in FIG. 12, the outer sheets 51, 51 and the top gusset sheet 52 overlap each other, and the outer sheets 51, 51 overlap each other in a Y shape, and the spout TM is held in an open state. Because it is not possible, it is suitable as a container to be used by squeezing out the filled liquid product with high viscosity, but the liquid product with relatively low viscosity is spouted along the mouth of the bottle container etc. It is not suitable as a container to be filled with liquid goods for refilling that is used by pouring into the mouth of bottle containers from .

  Then, the subject of this invention is providing the pouch container which can hold | maintain the formed spout in an open state.

  In order to solve the above problems, the invention according to claim 1 is provided with a single exterior sheet that forms a front part, a rear part, and a top gusset part by folding, and both side edges of the exterior sheet As a result of heat sealing, boundary portions between the top gusset portion, the front portion, and the back portion are each formed into a bag shape in an unsealed state, and one side edge of the exterior sheet is recessed inward. Accordingly, a spout forming portion protruding in the lateral direction is formed at the upper end portion of the spout, and the spout forming portion breaks the front portion and the back portion of the exterior sheet from the lower side. The present invention provides a pouch container having a knob for forming a pouch.

  The invention according to claim 2 is the pouch container of the invention according to claim 1, wherein the filling port for the contents is formed by cutting off the other side edge side of the upper end portion while leaving the spout forming portion. It is characterized by being.

  The invention according to claim 3 is the pouch container of the invention according to claim 1 or 2, wherein the spout forming part is configured to remove the top gusset part from the knob part to the front part and the rear part. A break line reaching the upper edge of the part is formed.

  As described above, in the pouch container according to the first aspect of the present invention, the boundary portions between the top gusset portion, the front portion, and the back portion are unsealed, so that the pick portion is picked and the tip of the spout forming portion is formed. After the spout is formed from the lower side, the tip end portion of the broken spout forming portion can be folded upward at the top gusset portion. As a result, the spout is held in a substantially triangular open state, so that the outer sheet is not in close contact and the spout is not blocked, and smooth filling is possible without squeezing out the filled liquid contents. Unlike the conventional pouch container, the liquid content can be transferred to the bottle container because the tip of the broken outlet formation portion is not completely separated from the pouch container. There is an advantage that the handleability when discarding the replaced pouch container as garbage is good.

  Further, in the pouch container of the invention according to claim 2, since the filling port for the contents is formed at the upper end portion, the filling of the contents is performed by using an existing filling device for filling the contents into the conventional pouch container. The effect that it can be performed is acquired.

  Further, in the pouch container of the invention according to claim 3, there is no need to form a break line in the top gusset portion that is folded between the front portion and the back portion during bag making, and the front portion and the back portion that are exposed to the outside. Therefore, there is an advantage that it is easy to manufacture.

  Hereinafter, embodiments will be described with reference to the drawings. A pouch container 1 shown in FIGS. 1 and 2 is used to fill liquid products such as shampoos and rinses for refilling bottle containers, and an aluminum sealant film made of polyethylene, polypropylene, or the like has aluminum on the outer surface. It is formed so as to be foldable in a flat state by a flexible sheet having a thickness of about 60 to 200 μm obtained by laminating a biaxially stretched polyester film on which a gas barrier sheet such as foil is laminated.

  As shown in FIGS. 1 and 2, the pouch container 1 includes a single outer sheet 11 that forms a front portion FS, a back portion BS, and a top gusset portion TG by folding the upper end portion into an M shape. And a bottom gusset sheet 12 that is folded inward from the lower part to form a bottom gusset part between the front part FS and the rear part BS formed by the exterior sheet 11, and the folded bottom gusset is formed. The peripheral edge of the sheet 12 is heat-sealed to the lower peripheral edge of the exterior sheet 11, and both side edges that are not heat-sealed to the gusset sheet 12 in the exterior sheet 11 are heat-sealed to form a bag shape. . In addition, the front part FS, the back part BS, and the top gusset part TG, which are formed by folding the exterior sheet 11, are simply connected via a crease line, and the continuous edges are connected to each other. It is not heat sealed.

  Moreover, the notch part 12a which mutually corresponds in the state folded in two is formed in the both-sides edge of the bottom gusset sheet | seat 12, respectively, and the lower end parts in the both-sides edge of the exterior sheet | seat 11 are via this notch part 12a. Partially heat sealed. In addition, the shaded display part in FIGS. 1-8 has shown the heat seal part.

  Further, by partially denting one upper side edge of the front part FS and the back part BS formed by the exterior sheet 11, the spout forming part 13 protruding to one side edge side at the upper end part is formed. In addition, the other side edge side of the upper end portion of the outer sheet 11 that has been folded is cut out by about half of the full width, so that the filling port 16 of the contents that opens upward at a position one step lower than the spout forming portion 13 is provided. (See FIG. 3 and FIG. 4), after filling the contents from the filling port 16, by heat-sealing the upper edges of the front portion FS and the back portion BS forming the filling port 16, The filling port 16 is closed.

  The spout forming portion 13 includes a top gusset portion TG left uncut at the upper end portion folded in an M shape, and a front portion FS and a back portion connected to the top gusset portion TG via a crease line. The upper end portion of the BS is configured, and both side edges of the top gusset portion TG and both side edges of the front surface portion FS and the back surface portion BS are heat-sealed with a predetermined width.

  The spout forming portion 13 includes a front portion of the exterior sheet 11 on the inner side of the heat seal edge where one side edge of the top gusset portion TG and one side edge of the front portion FS and the back portion BS are heat sealed. It has the knob | pick part 14 for fracture | rupturing FS and the back surface part BS from the lower side, and forming a spout, This knob | pick part 14 is picked and the front part FS and the back surface part BS in the exterior sheet 11 are fractured | ruptured. At this time, in order to improve the breakability, a break line 15 made of a half cut for improving the breakability is provided only at the front portion FS and the back portion BS of the exterior sheet 11 at the position indicated by the one-dot chain line in FIGS. Each is formed. When forming the spout, as described later, it is not necessary to break the top gusset portion TG and completely separate the tip of the spout formation portion 13, so that the top gusset portion TG has a half cut. The break line which consists of is not formed.

  In addition, a crease line F is formed at a position corresponding to the folding edge of the top gusset part TG on the front part FS and the back part BS of the exterior sheet 11 forming the spout forming part 13. The top gusset portion TG can be opened in a substantially flat state by bending the upper end portions of the front portion FS and the back portion BS in the spout forming portion 13 outward at the line of sight F.

  As shown in FIGS. 3 and 4, the pouch container 1 configured as described above is unsealed by cutting off the other side edge side of the folded upper end portion of the exterior sheet 11 to about half the full width. After filling the liquid content from the filling port 16 with the filling port 16 formed, the upper edges of the front portion FS and the back portion BS forming the filling port 16 are heat-sealed and sealed. (See FIGS. 1 and 2).

  When the liquid content filled and sealed in the pouch container 1 is refilled into a bottle container, the knob 14 is picked from the display state shown in FIG. The top gusset is formed by folding the front end portion FS and the back end portion BS of the exterior sheet 11 forming the spout forming portion 13 outward along the crease lines F and F, after forming the spout by breaking. When the portion TG is opened and the tip end portion of the broken spout forming portion 13 is folded upward by the top gusset portion TG, the spout 17 is held in a substantially triangular open state as shown in FIG. Therefore, the liquid content is poured out by grasping the trunk of the pouch container 1 and bringing the spout 17 along the mouth of the bottle container.
