Description

The present invention relates to a refillable storage container for storing toiletry items such as liquid detergent and fabric softener, and foods such as edible oil, liquid seasoning, and instant coffee.

Conventionally, refill storage containers have ensured pourability through shapes such as embossed parts, seals, and easy-open processing near the spout.

The shape of the seal that forms the spout is limited by the shape of the bottle to be refilled, and changing the shape of the easy-open seal may affect not only the pourability but also the cutability. Therefore, in recent years, many storage containers have been provided with an embossed part near the spout to assist in pouring.

For example, Patent Document 1 includes two sheets for forming a body part and a sheet for forming a bottom part disposed at the lower end between the sheets for forming a body part, and the peripheral edges of these sheets are thermally bonded. A self-supporting bag is disclosed. A spout portion for pouring out the contents is provided at the upper part of the two sheets for forming the body, and a ruled line for assembly is provided on the two sheets for forming the body at the spout portion.

By providing the above-mentioned assembly rules, the pouring spout section can be easily formed into a three-dimensional structure, and the contents can be poured smoothly without clogging.

However, in a storage container like the above-mentioned self-supporting bag, which is equipped with a spout that inflates the film itself near the spout to form a three-dimensional shape, when opening a part of the spout and pouring out the contents, , the base of the spout may swell excessively due to the pressure of the contents. As a result, the opening of the spout is pulled toward the bonded ends of the spout, and as the front and back films approach each other, the opening may become narrower. In this case, the problem arises that the opening is blocked and the contents are not poured out.

Furthermore, Patent Document 2 describes an opening assisting mechanism that is embossed into a substantially rectangular, substantially triangular, rhomboid, herringbone, circular, or oval shape on the portion that becomes the spout; A packaging bag with a pouring function is disclosed which is provided with a bending prevention mechanism.

With the opening assisting mechanism, a spout having a large cross-sectional area can be easily formed. In addition, the bending prevention mechanism prevents the spout from bending, making it possible to easily take out the contents while maintaining a stable flow until the end.

However, the formation of the embossed part in the pouring spout is generally done by a molding method using a metal mold, and in practice, in order to achieve the desired pourability, for example, It is difficult to reproduce the various detailed shapes including, and for this reason, it is difficult to achieve the desired pourability.

Hereinafter, examples of embodiments of the storage container according to the present invention will be described with reference to the drawings as necessary.

FIG. 1 is a front view showing a storage container 1 according to this embodiment. FIG. 2 is a cross-sectional view taken along line AA in FIG. FIG. 3 is an enlarged front view showing the upper part of the storage container 1. As shown in FIG. The storage container 1 is a refillable container, and is used, for example, as a pouch (bag-like flexible packaging). The inside of the storage container 1 is filled with liquid contents to replenish the main container, which is a refill destination container. Examples of the contents include liquid detergent, edible oil, and liquid seasoning.

As shown in FIGS. 1 and 2, the storage container 1 includes a front member 2 and a back member 3 joined to the front member 2. Further, a bottom member 4 is provided between the lower part of the front member 2 and the lower part of the back member 3. The front member 2, the back member 3, and the bottom member 4 are made of flexible plastic films (or sheets). This film is constructed by laminating a base material layer and a sealant layer. A film having a known structure used as a pouch can be applied to the front member 2, the back member 3, and the bottom member 4. As an example, the film has a two-layer structure consisting of a nylon (NY) film as the outer substrate layer and a linear low density polyethylene (LLDPE) film as the inner sealant layer.

The peripheral edge of the front member 2 and the peripheral edge of the back member 3 are joined to each other by heat-sealing a sealant layer having heat-adhesive properties to form a peripheral edge portion 5. This peripheral portion 5 includes a side portion 6, a top portion 7, and a spout seal portion 9 in FIG. The side sides of the front member 2 and the side sides of the back member 3 are joined to each other by heat-sealing a sealant layer having heat-adhesive properties to form a side piece portion 5. Similarly, in the lower part of the storage container 1, the front end 4A of the bottom member 4 and the lower end 2A of the front member 2 are joined to each other by heat fusion, with the bottom member 4 folded upward so as to be convex. Then, the rear end 4B of the bottom member 4 and the lower end 3A of the back member 3 are joined to each other by heat fusion. Further, the front end 4A and the rear end 4B of the bottom member 4 are joined to each other by heat fusion at both left and right ends. By joining the front member 2 and the back member 3 in this manner, a content storage section 8 for storing contents is formed between the front member 2 and the back member 3. When the content storage section 8 is filled with contents, the fold line 4C of the bottom member 4 moves downward due to the weight of the contents, and the bottom member 4 expands in the front-rear direction. Thereby, the volume of the storage container 1 is increased, and the storage container 1 is given independence. Note that, before the contents are filled into the contents storage section 8, the unfused portions of the upper side of the front member 2 and the upper side of the back member 3 are arranged at the upper part of the container as a filling opening. After the contents are filled into the content storage portion 8, the upper side of the front member 2 and the upper side of the back member 3 are joined to each other by heat-sealing a sealant having heat-adhesive properties, and the upper side 7 is It is formed. In addition, it is preferable that each base of the front member 2, the back member 3, and the bottom member 4 be a straight line in consideration of independence.

A spout channel 13 is provided between the spout 11 and the content storage section 8 . The spout channel 13 is constituted by the front member 2 and the back member 3 that are joined to each other, and communicates from the spout 11 to the content storage section 8 . That is, the contents stored in the contents storage section 8 pass through the pouring channel 13 and are poured out from the spout 11.

At a corner of the storage container 1, a spout seal part 9, which is also a part of the peripheral part 5, is provided so as to be continuous with the side part 6 and the top part 7, which are part of the peripheral part 5. Further, a spout forming portion 10 is provided, which includes a spout seal portion 9 that is a part of the peripheral edge portion 5 and forms a spout 11 by being removed. By removing the spout forming part 10, a spout 11 for pouring out the contents is formed. The position of the spout forming part 10 is not particularly limited as long as there is no problem in pouring out the contents. For example, in FIG. 1, the spout forming part 10 is provided in the upper left part of the storage container 1. The spout forming part 10 has a scheduled opening line 12 formed along the spout 11 . The spout 11 is formed by cutting the spout forming portion 10 along the planned opening line 12 and removing the spout forming portion 10. Note that the planned opening line 12 may be printed to indicate the planned opening line, but may also be subjected to laser processing such as half-cutting in order to improve straight cutability.

As shown in FIGS. 1 and 3, the pouring channel 13 has three embossed sections, a first embossed section 14, a second embossed section 15, and a third embossed section 16, and a first half embossed section. It has two half-cut lines consisting of a cut line 17 and a second half-cut line 18.

First, the three embossed parts will be explained. The first embossed portion 14 is formed in a convex shape that bulges outward, and the second embossed portion 15 and the third embossed portion 16 are formed in a concave shape that is depressed inward.

Here, the outward direction is the direction from the contents storage section 8 inside the storage container 1 toward the surface of the front member 2 or the back member 3 (the surface forming the outer surface of the storage container 1), and is the direction from the inside. is the opposite direction outward.

As shown in FIG. 3 , the first embossed portion 14 extends linearly from slightly in front of the spout 11 on the side opposite to the spout flow path 13 toward the content storage section 8 , and It is arranged so as to straddle the planned opening line 12 formed along the line. By doing so, the liquid can reliably flow toward the spout 11 from the bulge of the spout 11 formed by the first embossed portion 14, and the opening of the spout 11 can also be prevented from being blocked.

The second embossed portion 15 is spaced apart from the first embossed portion 14 and is provided above the first embossed portion 14 . The second embossed portion 15 also includes a first line portion 15A formed in a straight line that extends away from the first embossed portion 14 as it goes from the spout 11 toward the content storage portion 8; A second straight line is connected to the end 14C of the line portion 15A on the content storage section 8 side, and extends from the end 14C of the first line portion 15A toward the first embossed portion 14. It has a line portion 15B. The third embossed portion 16 is spaced apart from the first embossed portion 14 and is provided below the first embossed portion 14 . Further, the third embossed portion 16 includes a third line portion 16A formed in a straight line that extends away from the first embossed portion 14 as it goes from the spout 11 toward the content storage portion 8; A fourth straight line is connected to the end 15C of the line portion 16A on the content storage section 8 side, and extends from the end 15C of the third line portion 16A toward the first embossed portion 14. It has a line portion 16B.

The first embossed portion 14, the second embossed portion 15, and the third embossed portion 16 are formed by embossing the front member 2 and the back member 3. The first embossed portion 14, the second embossed portion 15, and the third embossed portion 16 are formed on both the front member 2 and the back member 3. The first embossed portion 14 formed on the front member 2 and the first embossed portion 14 formed on the back member 3 are provided at positions facing each other (positions overlapping each other when viewed from the front of the storage container 1). Similarly, the second embossed portion 15 formed on the front member 2 and the second embossed portion 15 formed on the back member 3 are provided at positions facing each other. Similarly, the third embossed portion 16 formed on the front member 2 and the third embossed portion 16 formed on the back member 3 are provided at positions facing each other.

The end PA of the first embossed part 14 opposite to the spout 11 is the end PC of the second embossed part 15 opposite to the spout 11, and the end PC of the third embossed part 16 is opposite to the spout 11. It is arranged at a position farther from the spout 11 than each of the end portions PE. In FIG. 3, the end PA of the first embossed part 14 opposite to the spout 11 is the same as the end PC of the second embossed part 15 opposite to the spout 11 and the spout of the third embossed part 16. It is arranged at a position farther from the spout 11 than virtual vertical lines Ra and Rb that are perpendicular to the linear first embossed part 14 from each end PE on the opposite side to the spout 11 .

In addition, the end PB of the first embossed part 14 on the spout 11 side is the end PD of the second embossed part 15 on the spout 11 side, and the end PF of the third embossed part 16 on the spout 11 side. It is arranged at a position closer to the spout 11 than each of the spout 11. In FIG. 3, the end PB of the first embossed part 14 on the spout 11 side is the end PD of the second embossed part 15 on the spout 11 side, and the end of the third embossed part 16 on the spout 11 side. It is arranged at a position closer to the spout 11 than virtual vertical lines Rc and Rd that are perpendicular to the linear first embossed part 14 from each part PF.

As described above, by arranging the ends PA and PB of the first embossed part 14 as described above, the portion from the root of the spouting channel 13 to the spout 11 swells outward. The contents can be guided to the spout 11 side more smoothly, and the opening of the spout 11 can be prevented from being blocked.

When opening the spout 11 and pouring out the contents, the linear first embossed part 14, which is formed in a convex shape and swells outward, allows the liquid to flow outward in the pouring channel 13 when pouring out the contents. It expands in the direction. If only the first embossed portion 14 is used, the root of the pouring channel 13 (on the side of the contents storage portion 8) may swell excessively due to the pressure of the contents. As a result, the opening of the spout 11 is pulled toward the bonded ends of the spout 11, and as the film of the front member 2 and the film of the back member 3 approach each other, the opening may become narrower. In this case, the problem arises that the opening is blocked and the contents are not poured out. Therefore, the second embossed part 15 and the third embossed part 16, which are arranged to sandwich the first embossed part and are formed in an inwardly concave shape and have a bent part as described above, are arranged to sandwich the first embossed part. Excessive swelling of the root of the channel 13 is suppressed, thereby making it difficult for the opening of the spout 11 to become clogged.

In the second embossed portion 15, the first line portion 15A and the second line portion 15B are provided at an angle α. Here, the angle α is the angle of the side facing the first embossed portion 14 among the angles formed by the first line portion 15A and the second line portion 15B. For example, in the second embossed portion 15 shown in FIGS. 1 and 3, the angle α between the first line portion 15A and the second line portion 15B is 130 degrees. Considering the effect of suppressing excessive bulge at the base of the spouting channel 13 by the second embossed section 15 described above, the second line section 15B is designed to extend toward the content storage section 8 side of the spouting channel 13. Preferably, the angle α is 90 degrees or more and less than 180 degrees.

In the third embossed portion 16, the third line portion 16A and the fourth line portion 16B are provided at an angle β. Here, the angle β is the angle formed by the third line portion 16A and the fourth line portion 16B on the side facing the first embossed portion 14. For example, in the third embossed portion 16 shown in FIG. 1, the angle β between the third line portion 16A and the fourth line portion 16B is 130 degrees. Considering the effect of suppressing the excessive swelling of the base of the spouting channel 13 by the third embossed section 16 described above, it is necessary to make the fourth line section 16B extend toward the content storage section 8 side of the spouting channel 13. Preferably, the angle β is 90 degrees or more and less than 180 degrees.

Further, by making the above-mentioned angle α and angle β equal, the contents are guided to the spout 11 side more smoothly.

In the second embossed part 15, a straight second line part 15B extending from the end 14C of the first line part 15A to approach the first embossed part 14, and in the third embossed part 16, A fourth line part 16B formed in a straight line extending from the end 15C of the third line part 16A to approach the first embossed part 14 is connected to the first straight embossed part 14. Formed line-symmetrically. In this way, by forming the second line portion 15B and the fourth line portion 16B line-symmetrically with respect to the first embossed portion 14, the contents are guided to the spout 11 side more smoothly. Further, the longitudinal dimension of the linear third line portion 16A extending away from the first embossed portion 14 in the third embossed portion 16 is the same as that of the first embossed portion in the second embossed portion 15. It is longer by 1 mm or more than the longitudinal dimension of the linear first line portion 15A extending away from the portion 14. The third line portion 16A is located at the lowest position when the storage container 1 is tilted toward the spout 11 for refilling the contents. Therefore, by forming the longitudinal dimension of the third line part 16A to be 1 mm or more longer than the longitudinal dimension of the first line part 15A as described above, it is possible to pour the storage container 1 for refilling the contents. When tilting toward the outlet 11 side, the contents are guided to the spout 11 side more smoothly.

The end PD of the second embossed part 15 on the spout 11 side is closer to the spout 11 than the imaginary vertical line LB that touches but does not intersect with the end of the spout sealing part 9 on the upper side 7 side on the content storage section 8 side. located on the side. The end PF of the third embossed part 16 on the spout 11 side is closer to the spout than the imaginary vertical line LC that touches but does not intersect with the end of the spout sealing part 9 on the side part 6 on the content storage section 8 side. Located on the 11th side. That is, both the second embossed part 15 and the third embossed part 16 are arranged closer to the spout 11. Here, the virtual vertical line LB and the virtual vertical line LC are lines on the front member 2 that are perpendicular to the linear base of the front member 2, respectively. Further, the virtual vertical line LB and the virtual vertical line LC are lines on the back member 3 that are perpendicular to the linear base of the back member 3, respectively. As described above, by arranging both the second embossed part 15 and the third embossed part 16 closer to the spout 11, the bulge of the spout 11 formed by the first embossed part 14 can be avoided. The liquid can be reliably flowed toward the spout 11, and the opening of the spout 11 can be prevented from being clogged.

The end PD of the second embossed part 15 on the spout 11 side and the end PF of the third embossed part 16 on the spout 11 side are provided so as not to contact the peripheral edge 5 of the storage container 1, respectively. By doing this, the second embossed part 15 and the third embossed part 16 are prevented from being crushed by the heat-sealed peripheral part 5, and the bulge formed by the second embossed part 15 and the third embossed part 16 are prevented from being crushed. It becomes possible to maintain the respective bulges formed by the embossed portions 16. As described above, the peripheral portion 5 includes the side portion 6, the upper portion 7, and the spout seal portion 9.

The arrangement of the first embossed part 14, the second embossed part 15, and the third embossed part 16 in the pouring channel 13 is appropriately set according to the overall dimensions of the storage container 1, the physical properties of the contents, etc. It's fine. For example, by setting the position of the first embossed part 14 in the spout 11 above the center of the spout 11, when the storage container 1 is tilted and the contents are poured out, the contents are transferred to the first embossing part 14. The liquid can be poured from a position above the center of the spout 11 along the embossed part 14 .

The lengthwise dimension of the first embossed portion 14 may be set as appropriate depending on the overall dimensions of the storage container 1, the physical properties of the contents, and the like. Similarly, the longitudinal dimension of the second embossed part 15 (the longitudinal dimension of the first line part 15A and the longitudinal dimension of the second line part 15B) is the overall size of the storage container 1 and the contents. It may be set as appropriate depending on the physical properties of the object. Similarly, the longitudinal dimension of the third embossed part 16 (the longitudinal dimension of the third line part 16A and the longitudinal dimension of the fourth line part 16B) is the overall dimension of the storage container 1 and the longitudinal dimension of the third line part 16A. It may be set as appropriate depending on the physical properties of the contents. In addition, the widthwise dimension of the first embossed part 14, the widthwise dimension of the second embossed part 15, and the widthwise dimension of the third embossed part 16 are the overall dimensions of the storage container 1 and the contents. It may be set as appropriate depending on the physical properties of the material. The widthwise dimension of the first embossed part 14, the widthwise dimension of the second embossed part 15, and the widthwise dimension of the third embossed part 16 are constant along the longitudinal direction or the stretching direction. It can be different or it can change. Here, the width direction is a direction perpendicular to the longitudinal direction and substantially parallel to the surface of the front member 2 or the surface of the back member 3.

Next, two half-cut lines will be explained. FIG. 4 is a schematic cross-sectional view taken along line XX in FIG. 3. As shown in FIG. 4, the first half-cut line 17 and the second half-cut line 18 are respectively formed on the outside of the front member 2 and the back member 3 by laser processing in a direction perpendicular to the film. By forming the respective grooves of the first half-cut line 17 and the second half-cut line 18, the expansion of the spout 11 by the first embossed part 14 is facilitated when pouring out the contents.

The depth of the grooves of these half-cut lines naturally varies depending on the thickness of the base material layer 21 and the sealant layer 22, but as shown in FIG. is preferred. If the depth of this groove is shallow, the effect of promoting the bulge of the spout 11 by the first embossed part 14 will be small, but if it is too deep and reaches the inside of the sealant layer 22, the front member 2 or the back member 3 may be cut. This is because there is a risk that the contents may leak.

Examples of methods for providing the first half-cut line 17 and the second half-cut line 18 include laser machining using a focused beam or kaleido beam, mechanical machining using a cutter, grindstone, etc., thermal processing using a heat bar, etc. In order to form linear grooves only on the outer base material layer 21 constituting the laminated film forming the storage container 1, processing due to the generation of processing waste due to machining and the adhesion of resin due to thermal processing with a heat bar is necessary. In order to avoid problems such as instability of the state, it is preferable to form by laser processing. Laser processing using a kallide beam is particularly suitable, and if necessary, a plurality of first half-cut lines 17 and/or second half-cut lines 18 can be formed on the outer base material layer 21 of the laminated film. I can do it.

As shown in FIG. 3, the first half-cut line 17 is spaced apart from the first embossed part 14 and the second embossed part 15, and is located above the first embossed part 14 and connected to the second embossed part 15. It is located below. The second half-cut line 18 is spaced apart from the first embossed part 14 and the third embossed part 16 and is provided below the first embossed part 14 and above the third embossed part 16. It will be done. The first half-cut line 17 and the second half-cut line 18 are formed on both the front member 2 and the back member 3. The first half-cut line 17 formed on the front member 2 and the first half-cut line 17 formed on the back member 3 are provided at positions facing each other (positions overlapping each other when viewed from the front of the storage container 1). It will be done. Similarly, the second half-cut line 18 formed on the front member 2 and the second half-cut line 18 formed on the back member 3 are provided at positions facing each other. As described above, the number of each of the first half-cut lines 17 and the second half-cut lines 18 may be plural as necessary.

The first half-cut line 17 is a first line portion 15A whose end point SA on the opposite side to the spout 11 is the so-called bending point of the second embossed portion 15. It is provided so as to be located closer to the spout 11 than the end 14C on the content storage section 8 side. Further, the second half-cut line 18 is a third line portion where the end point SB of the second half-cut line 18 on the opposite side to the spout 11 is the so-called bending point of the third embossed portion 16. It is provided so as to be located closer to the spout 11 side than the end portion 15C of the content storage section 8 side of the end portion 16A. In FIG. 3, the end point SA of the first half-cut line 17 on the opposite side to the spout 11 is an imaginary perpendicular to the first embossed part 14 from the so-called bending point 15C of the second embossed part 15. It is located closer to the spout 11 than the vertical line Wa. In addition, the end point SB of the second half-cut line 18 on the opposite side to the spout 11 is a virtual vertical line that is perpendicular to the first embossed part 14 from the so-called bending point 16C of the third embossed part 16. It is located closer to the spout 11 than Wb.

By providing the end point SA of the first half-cut line 17 on the side opposite to the spout 11 and the end point SB of the second half-cut line 18 on the side opposite to the spout 11 at the above positions,
The following effects of the second embossed portion 15B and the third embossed portion 16B are not hindered. The effect is that the parts where the second embossed part 15B and the third embossed part 16B are provided tend to protrude inward, thereby suppressing excessive swelling of the root of the spouting channel 13 due to the pressure of the contents. This means that it is possible. Therefore, the first half-cut line 17 and the second embossed part 17 promote the bulge of the spout 11 due to the first embossed part 14 while exhibiting the above-mentioned effects of the second embossed part 15B and the third embossed part 16B. The effect of the half-cut line 18 can also be exhibited.

The shapes of the first half-cut line 17 and the second half-cut line 18 should be particularly effective as long as they promote the expansion of the spout 11 by the first embossed part 14. It is desirable that both size and depth be small.

The arrangement of the first half-cut line 17 and the second half-cut line 18 in the pouring channel 13 may be appropriately set according to the overall dimensions of the storage container 1, the physical properties of the contents, and the like. Further, the longitudinal dimensions of the first half-cut line 17 and the second half-cut line 18 may be set as appropriate depending on the overall dimensions of the storage container 1, the physical properties of the contents, and the like.

FIG. 5 is a front view showing the angles formed by the embossed portion and the half-cut line on the spout 11 side at the upper part of the storage container 1. Here, the spout 11 side of the second embossed part 15 refers to the straight first line part 15A, and the spout 11 side of the third embossed part 16 refers to the spout 11 side of the third embossed part 16. This is a third linear portion 16A. As shown in FIG. 5, a linear first embossed portion 14, a linear first line portion 15A of the second embossed portion 15, and a linear third line portion of the third embossed portion 16. Angles a, b, c, and d formed by 16A, the first half-cut line 17, and the second half-cut line 18 are all equal. Here, the angle a is the angle between the first line part 15A and the first half-cut line 17, and the angle b is the angle between the first half-cut line 17 and the first embossed part 14. c indicates the angle between the first embossed portion 14 and the second half-cut line 18, and angle d indicates the angle between the second half-cut line 18 and the third line portion 16A.

As mentioned above, by making all the angles a, b, c, and d equal, the contents are guided to the spout 11 side more smoothly.

Next, the operation of the storage container 1 configured as described above during use will be described. FIG. 6 is an enlarged perspective view of the upper part of the storage container. FIG. 7 is a diagram showing a state in which the storage container 1 is in use.

First, the user cuts out and removes the spout forming part 10 of the storage container 1 filled with the contents along the planned opening line 12, and opens the spout 11 as shown in FIG. As shown in FIG. 7, the spout 11 is inserted into the opening 101 of the main container 100 while the storage container 1 is tilted, and the contents of the storage container 1 are refilled into the main container 100.

At this time, the weight (pressure) of the contents is applied to the pouring channel 13. Since the pouring channel 13 is provided with the first embossed portion 14 formed in a convex shape, the portion of the pouring channel 13 where the first embossed portion 14 is provided bulges outward. Furthermore, since the pouring channel 13 is provided with a first half-cut line 17 and a second half-cut line 18 formed from the outside of the film, the pouring flow caused by the first embossed portion 14 is The bulge of the passageway 13 is encouraged. At the same time, the pouring channel 13 has a second embossed part 15 formed in a concave shape above the first embossed part 14 and a third embossed part formed in a concave shape below the first embossed part 14. 16, the portion of the pouring channel 13 where the second embossed portion 15 and the third embossed portion 16 are provided tends to protrude inward. Therefore, the portion of the spouting channel 13 where the second embossed part 15 and the third embossed part 16 are provided is suppressed from swelling, and the root of the spouting channel 13 is prevented from swelling excessively. . This makes it difficult for the opening of the spout 11 to become clogged. At the same time, the opening of the spout 11 is moved in the direction in which the first embossed part 14 formed on the front member 2 and the first embossed part 14 formed on the back member 3 are separated from each other, and The first half-cut line 17 formed on the front member 2 and the first half-cut line 17 formed on the back member 3 are spaced apart from each other, and the second half-cut line 18 formed on the front member 2 and the second half-cut line 18 formed on the back surface member 3 can be suitably expanded in the direction in which they are separated from each other.

Further, the second embossed part 15 formed in a concave shape is a second line part 15B formed in a straight line that extends from the end 14C of the first line part 15A to approach the first embossed part 14. has. Further, the third embossed part 16 formed in a concave shape is connected to a fourth line part 16B formed in a straight line that extends from the end 15C of the third line part 16A to approach the first embossed part 14. has. Since the portion of the spouting channel 13 where the second line portion 15B and the fourth line portion 16B are provided tends to protrude inwardly, excessive swelling of the root of the spouting channel 13 due to the pressure of the contents is prevented. It can be suppressed. As a result, while pouring out the contents, the front member 2 and the back surface are aligned at the positions of the first embossed part 14 formed in a convex shape, the first half-cut line 17, and the second half-cut line 18. The spout 11 is suitably opened by stabilizing the folded state in which the member 3 is mountain-folded so as to be convex toward the outside of the container, and the spout 11 is suitably opened, and the contents storage section 8 side of the spout passage 13 is stabilized. It is possible to maintain a suppressed state of swelling. Therefore, the contents are smoothly guided to the pouring spout 11 side through the internal space which is convexly folded into a convex shape toward the outside of the container, and the user does not have to interrupt the pouring operation in the middle. The contents can be poured out quickly without any trouble.

In conventional storage containers, the root of the spout channel expands excessively due to the pressure of the contents, pulling the spout opening toward the glued ends of the spout, causing the spout opening to become clogged. There were cases where I ended up doing it. Further, in order to prevent such openings from being blocked and improve pourability, it is sometimes necessary to reproduce the shape of the fine embossed portions. On the other hand, in the storage container 1 according to the present embodiment, since the pouring channel 13 has the second embossed part 15 and the third embossed part 16, the opening of the spout 11 is not blocked. The contents can be poured out while the flow rate of the contents is stabilized. It is also possible to increase (adjust) the pouring flow rate by pushing the content storage section 8 of the storage container 1. In addition, it also has a first half-cut line 17 that helps the first embossed part 14 bulge out of the spout 11, and the first half-cut line 17 has a fine embossed part shape to improve pourability. No need to reproduce.

Regarding other configurations such as outer diameter dimensions, the storage container of Comparative Example 1 is the same as the storage container 1 of Example 1.

The content pouring performance of each storage container of Example 1 and Comparative Examples 1 to 7 described above was evaluated. Specifically, each storage container was first filled with 320 ml of content (tap water) and sealed. Subsequently, the spout was opened and the storage container was tilted so that the spout faced downward. As a result, the content (tap water) was poured out by free fall, and the time elapsed from the start of dispensing of the content (tap water) to the completion of dispensing was measured. The measurement results are shown in Table 1.

In Table 1, "〇" in the "Judgment" column indicates that the contents can be refilled smoothly without any resistance, and "△" indicates that the contents may be slightly caught in the pouring channel or opening. ``x'' indicates that the spout is blocked or the content is poured slowly. Only the storage container 1 of Example 1 was evaluated as ○. On the other hand, in the storage containers of Comparative Example 2 and Comparative Example 4, the spout was blocked and the judgment was x, and in the storage container of Comparative Example 5, the spout was not blocked, but the judgment was x. In addition, in the other storage containers of Comparative Examples 1, 3, 6, and 7, although the spout was not blocked, the judgment was Δ.

Furthermore, in the storage container 1 of Example 1, the contents could be poured out more quickly than in the case of each of the storage containers of Comparative Examples 1 to 7. As described above, in Example 1 using the storage container 1 according to the present embodiment, the contents can be quickly poured out without the opening of the spout being blocked and the contents being poured out at a stable flow rate. It has been confirmed that this is possible.

In addition, conventionally, there are storage containers in which a separate member, such as a cylindrical part, is provided at the spout in order to encourage the bulge of the spout, but providing a separate member increases the cost, so it is not possible to use the optimal member. There are problems such as the need to select the appropriate one, or the bulkiness during transportation and storage. On the other hand, the embodiments of the present invention reduce costs, do not require the effort of selecting components, and do not have the problem of being bulky during transportation or storage.

The embodiments disclosed this time should be considered to be illustrative in all respects and not restrictive. The scope of the present invention is indicated by the claims rather than the above description, and it is intended that all changes within the meaning and range equivalent to the claims are included.
