Description

  The present invention relates to a spout and a zippered container including a spout (also referred to as a spout) that pours a container such as a liquid, and a zipper that can enclose a filling larger than the diameter of the spout.

  As a container for containing a storage object such as a liquid, a peripheral part of a sheet-like member formed of synthetic resin or the like is welded, and a spout for pouring the storage object is interposed between the sheet-like members and welded. Is known. Such containers are used in various fields because they are inexpensive and easy to handle.

  The above-described container can be used for beverages, for example, but cannot be used in a special usage mode in which a large enclosure is enclosed and the pouring operation is performed little by little. For example, when producing homemade fruit liquor, it is necessary to enclose fruit and icing sugar (encapsulated material) in the accommodating part and accommodate shochu, but contain the encapsulated substance because the diameter of the spout is small. It cannot be enclosed in the part. Moreover, even if it is going to cool by putting ice in a drink, the diameter of a spout is too small and ice cannot be enclosed.

  Therefore, for example, Patent Document 1 discloses a spout-equipped container that can enclose and take out a large-diameter enclosure with a zipper. Since this container is provided with a zipper that can be sealed and opened in an opening formed at one end of the container, an enclosure having a diameter larger than that of the spout can be enclosed in the accommodation section by opening the zipper, and Can be taken out from the storage unit. Moreover, in the state which sealed the zipper, only a liquid can be poured out from a spout and it can utilize in the above usage modes.

Japanese Patent No. 4986309

  However, when the above-described prior art container is used, there is a problem that the stored liquid or the like leaks when the load on the zipper is large. Specifically, as shown in FIG. 1 of Patent Document 1, when the zipper is provided on the upper edge (between the sheet-like members), if the container is tilted when the liquid is poured out, the load of the stored item is applied to the zipper. For this reason, the close contact of the zipper cannot be maintained, and the contained liquid may leak out. Even when the spout and zipper are closed, if the container is turned upside down, tilted, or shaken, and the load of the load is applied to the upper edge, the zipper cannot be kept in close contact with the liquid. May leak.

  The present invention has been made by paying attention to such a problem, and provides a container with a spout and a zipper that can enclose a filling larger than the diameter of the spout and can prevent leakage of a container such as a liquid. The purpose is to do.

  In order to achieve the above-described object, the container with a spout and a zipper according to the present invention includes a container body that forms a container for storing contents by stacking sheet-like members and welding the periphery thereof; The spout is interposed at the edge of the sheet-like member, and pours out the contents, and the overlapping portion having an opening on the surface of the stacked sheet-like member, and the opening is sealed in the overlapping portion. A zipper that can be opened is provided.

  In the container having the above-described configuration, the zipper can be opened, and a large-diameter enclosure can be enclosed and removed from the housing portion. In addition, in a state where the zipper is sealed and the spout is opened, it is possible to pour out the stored matter other than the enclosed matter such as liquid from the spout. Since the said zipper forms an overlap part on the surface of a sheet-like member and is provided in the overlap part, compared with the case where it provides in the inner surfaces of a sheet-like member, it can make it difficult to receive the pressure by the load of an accommodation thing. Therefore, the pressure applied to the zipper is reduced, the close contact of the zipper can be maintained, and leakage of the liquid to be stored can be prevented.

  Usually, when the container is tilted or turned upside down, the load of the stored item is strongly applied to a portion where the stored item is gathered, and that portion is the periphery of the storing unit. When the zipper is disposed on the opposite inner surface of the peripheral edge as in the prior art, the zipper may be strongly subjected to a load due to the load of the contents and the close contact portion may be opened, causing liquid leakage and the like. . On the other hand, in the configuration of the present invention, since the zipper is disposed on the overlapping portion of the surface of the sheet-like member, the pressure acting on the zipper portion acts in the zipper engagement direction, so that the zipper is opened. This makes it difficult to apply pressure. That is, since the load applied to the zipper is suppressed to a low level, leakage of liquid to be stored can be prevented.

  The container having such a structure is suitable for an application in which a solid having a large diameter and a liquid such as the above-mentioned home-made fruit liquor or ice water are mixed, and the liquid is poured out. It is also suitable as a container to be taken out regardless of the state of thawing. In addition, it can be widely used as a simple container that does not easily leak or leak even if it falls over or shakes.

  According to the present invention, a spout can be used to pour liquid or the like from a spout, and to enclose and take out an enclosure larger than the diameter of the spout by a zipper, and to prevent leakage of the contents from the zipper when the zipper is sealed And a zippered container.

(A) And (B) is sectional drawing which shows the formation position of the zipper in the conventional container, respectively.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 to 3 are views showing a spout and a container with a zipper (hereinafter referred to as a container) according to an embodiment of the present invention, FIG. 1 is a plan view of the container, and FIG. The perspective view of the container in the state which pulls out a tear piece, and FIG. 3 are sectional drawings along the AA line of the container shown in FIG.

  The container 1 according to the present embodiment includes a synthetic resin sheet-like member (3a1, 3a2) that is flexible and formed in a substantially rectangular shape, and a synthetic resin sheet-like member 3b having substantially the same shape. The container body 5 having the housing portion 5A is formed by welding the peripheral edge portion shown by oblique lines with a heat bar or the like. The sheet-like member is, for example, a laminate of PET (polyethylene terephthalate) / PEF (polyethylene film), a laminate of ONY (stretched nylon) / PEF (polyethylene film), OPP (biaxially stretched polypropylene) / PEF (polyethylene film). In addition, for such a laminated structure, aluminum foil, transparent vapor deposition, aluminum vapor deposition, EVOH (ethylene / vinyl alcohol copolymer), etc., for moisture and oxygen barriers. You may comprise combining these films.

  As shown in FIG. 3, the sheet-like members (3 a 1, 3 a 2) are on one side (front surface) of the container body 5, and the sheet-like member 3 b is on the other side (back surface) of the container body 5. Is superimposed. On the surface, as shown in the drawing, the lower end of the sheet-like member 3a1 and the upper end of the sheet-like member 3a2 are arranged so as to overlap each other with a certain width in the vertical direction, and the overlapping portion 7 is formed. In this case, the overlapping portion is formed by forming any surface of the sheet-like member constituting the container body by a plurality of sheets and overlapping a part of the plurality of sheet-like members. good. The overlapping portion 7 in the present embodiment is formed so that the sheet-like member 3a1 is on the lower side and the sheet-like member 3a2 is on the upper side among the plurality of sheet-like members, but may be reversed. Such an overlapped portion 7 is not necessarily formed on the surface. For example, the sheet-like member 3b on the back surface may have the same two-sheet configuration, and the overlap portion may be formed on the back surface, or the overlap portion may be formed on both the front surface and the back surface. Furthermore, the number of overlapping portions 7 formed on the front and back surfaces is not limited to one, and a plurality of overlapping portions 7 may be formed.

  The container 1 may have a bag structure without a bottom surface by overlapping and welding the peripheral portions of the sheet-like members (3a1, 3a2), 3b, but in this embodiment, a separate bottom sheet is further provided. The bottom wall 9 is formed by thermally welding the sheet and the two front side sheets 3a2, 3b to each other, and the container 1 is a self-supporting bag. The size, shape, arrangement, etc. of the sheet-like members (3a1, 3a2) and 3b can be appropriately modified according to the purpose of use. / The aspect ratio is preferably set to less than 1 (horizontal shape). As described above, the vertically long shape is easier to hold the container 1 and easier to pour out a stored item such as a liquid.

  One of the upper corners of the container body 5 has the sheet members 3a1 and 3b overlapped in advance obliquely, and the corner part (cut edge part) 4e contains the contents accommodated in the accommodating part 5A. A spout 10 for pouring out an object is provided. The configuration of the spout 10 is not particularly limited, but in the present embodiment, a welded portion 10a having a boat-shaped cross section and a cylindrical portion 10b that protrudes from the corner portion 4e and has a cylindrical shape are provided. The welded portion 10a is attached by being interposed and welded to the corner portion 4e of the stacked sheet-like member. In addition, the opening part (screw type cap 10c) for opening / sealing the opening part is detachably attached to the opening part 10b so that the contents in the storage part 5A can be poured out little by little. It has become.

  The mounting position of the spout 10 is not limited to the corner portion 4e as long as it is configured as a self-supporting bag as in this embodiment, and the upper edge portion 4a of the container body 5 or the side. It is preferable that the edge portions 4b and 4d are formed above the overlapping portion 7. This is because, if formed below the overlapping portion 7, even when the container 1 is not inclined, the filled liquid or the like may flow out when the spout 10 is opened.

  However, depending on the application, the spout 10 may be disposed on the lower edge 4c of the container body 5 or on the side edges 4b and 4d in the vicinity of the lower edge 4c. For example, when the spout 10 having a lever-type sealable structure is disposed on the lower edge 4c, a glass is placed on the bottom of the spout 10 and the lever 1 is operated without tilting the container 1. Then, the contained liquid or the like can be poured out.

  The overlapping portion 7 is provided with a zipper (chuck) 20 for closely adhering and opening the overlapping sheet-like members 3a1 and 3a2. The zipper 20 is formed, for example, at a lower end portion of the sheet member 3a1 in the lateral direction over substantially the entire length, and at an upper end portion of the sheet member 3a2 and formed in the lateral direction over the entire length in the concave groove 20a. It is possible to comprise from the convex part 20b to engage. The zipper 20 that engages with such unevenness can be tightly opened by the user, and opening the container 5A opens in the lateral direction (opening 7a is formed as shown in FIG. 4). In addition, an enclosure having a diameter larger than that of the mouth portion 10b of the spout 10 can be enclosed in the housing portion 5A and can be taken out from the housing portion 5A.

  In order to ensure a sufficient amount of inclusions to be sealed from the opening 7a of the overlap portion 7, it is preferable that the formation position of the overlap portion 7 is as close as possible to the upper edge portion 4a. On the other hand, when the container 1 is tilted, turned upside down, or tilted, the vicinity of the upper edge portion 4a is a place where the load of the contents is applied. Therefore, when the zipper 20 is disposed in the vicinity of the upper edge portion 4a. The liquid leakage as described above is a cause, and it is preferable to form it at a certain distance from the upper edge portion 4a. That is, when the arrangement position of the zipper 20 approaches the edge side, the inner wall surface that defines the accommodating portion 5A is gradually inclined, and a load for opening the zipper 20 from the accommodated material acts greatly on that portion. Resulting in. For this reason, it is preferable to arrange | position the zipper 20 in the position in which the inner wall surface which prescribes | regulates an accommodating part is not largely inclined in the accommodation state.

  Specifically, the amount of liquid (maximum liquid storage position) stored in the storage unit is specified by the position of the spout 10 disposed in the sheet-like member. In this case, if the container 1 is configured as a self-supporting bag and the spout 10 is disposed on the upper edge side (corner portion 4e) as in this embodiment, the liquid is almost fully contained. As shown in FIG. 1, the maximum liquid storage position is near the lower end position H in the height direction of the welded portion 10 a of the spout 10. As described above, considering the balance between securing the amount of large-diameter enclosure and preventing liquid leakage without applying a large load to the zipper 20, the horizontal zipper 20 is disposed at the lower end. It is preferable to set the distance 35 to 40% from the position H (L1 is set to 35 to 40% when the distance L from the lower end position H to the lower end 4C of the lower edge 4c is 100%). That is, when the zipper 20 is formed at a height of less than 35% from the lower end position H, the load due to the load applied to the zipper 20 acts greatly and the liquid easily leaks. If the height is more than 40%, the amount of the sealed material that can be sealed from the opening 7a becomes small, and the advantage that the sealed material having a large diameter can be sealed is reduced (the zipper 20 is moved from the lower end position H to 50%). %), It is considered the most preferable position because the load hardly acts, but the enclosed amount becomes small). It should be noted that the above zipper 20 is disposed at a particularly preferable position because a large pressure acts on the zipper 20 in a container body having a rectangular horizontal side / longitudinal ratio of 1 or more (horizontal shape). It becomes an aspect.

  The arrangement position of the zipper 20 can be defined by the length (height) in the vertical direction of the sheet-like members 3a1 and 3a2. For example, when the sheet-like members 3a1 and 3a2 have the same height, the zipper 20 can be disposed so as to be located near the center of the upper edge portion 4a and the lower edge portion 4c. That is, as described above, in order to dispose the zipper 20 at a height of 35 to 40% from the lower end position H, the position of the overlapping portion 7 is adjusted by the height of the sheet-like members 3a1 and 3a2, and the overlapping portion 7 is adjusted. What is necessary is just to finely adjust the arrangement | positioning position of the zipper 20 in.

  It is preferable that a tear piece 30 for releasing the opening of the zipper 20 is provided in the overlapping portion 7. The tear piece 30 is torn from the upper edge 3a2 'of the sheet-like member 3a2, and is attached to the upper sheet-like member 3a2 so as to be peeled off from the surface 3a1' of the sheet-like member 3a1. The piece 30 can guarantee an unused state, and can further prevent contamination of foreign substances and foreign matters into the accommodating portion 5A. For example, when used for the production of fruit wine, the container 5A is kept clean in an unused state, so that it is convenient that the container need not be boiled in advance.

  The tear piece 30 has a string shape, and is attached to the upper side of the zipper 20 in the overlap portion 7 so as to be substantially parallel to the zipper 20. The tear piece 30 has a knob 30a at the left end, and this knob 30a is embedded and attached to the left side edge 4d of the overlapping portion 7, and has a cut formed in the side edge 4d. Can be extruded from the back. As shown by the arrow in FIG. 2, by pulling out the extruded knob 30a, the tear piece 30 is peeled off from the upper end edge 3a2 'of the sheet member 30a2, and a tear is formed on the upper side of the zipper 20, and from this tear As described above, the zipper 20 that is engaged with the concave and convex portions can be opened. The tear piece 30 is attached so as to be peeled off from the container 1 when it is pulled out to the right end of the peripheral edge 4 b on the right side of the overlapping portion 7.

  Next, the usage method of the container 1 having the above-described configuration will be described with reference to FIGS.

  First, the grip piece 30a at the left end of the tear piece 30 is pushed out from the back surface along the cut of the left side edge portion 4d, and the pushed handle piece 30a is pulled out to the right side, thereby generating a tear on the upper side of the zipper 20 Let Then, the zipper 20 is opened from the tear, and the large-diameter inclusion 15 (fruit, icing sugar) is enclosed from the opening 7a that appears (FIG. 4, FIG. 7A).

  After enclosing the large-diameter inclusion 15 and sealing the zipper 20 (FIG. 7B), the cap 10c of the spout 10 is opened and the shochu is poured (FIGS. 5 and 7C). )). Shochu can be injected to a height near the position where the spout 10 is welded. At the time of injection, for example, as shown in FIG. 5, a funnel 100 may be used for the spout 10 and the shochu may be poured. After injecting the shochu, the cap 10c of the spout 10 is sealed, and the container 1 is stored until the fruit wine is aged (FIG. 6).

  At the time of storage, the container 1 can be placed independently by the bottom wall 9 welded to the bottom. Even when the container 1 falls down due to external vibration or the like at the time of storage, the zipper 20 is disposed in the overlapping portion 7 formed on the surface of the sheet-like member. Since the load due to the load is kept low, it is possible to avoid the stored fruit wine from leaking out of the container 1.

  Specifically, as shown in FIG. 7C, a pressure as indicated by an arrow acts on the sheet-like member (side wall portion) from within the accommodating portion 5A. By forming the overlapped portion 7 and disposing the zipper 20 that engages with the concave and convex portions, the direction in which the pressure acts and the direction in which the concave and convex engagement is performed are substantially the same, and it becomes difficult to apply pressure to open the zipper 20. . That is, since the load applied to the zipper 20 is suppressed to a low level, leakage of liquid to be stored can be prevented.

  In contrast, in the conventional spout and zippered containers 40 and 50 shown in the cross-sectional view of FIG. 8, the sheet-like members (the inner surfaces of the sheet-like member 3a (front surface) and the sheet-like member 3b (back surface) are arranged. Since the zipper 20 is disposed between the zipper 20, the load of the contents acts strongly on the zipper 20, which causes liquid leakage. Specifically, when the zipper 20 is formed in the vicinity of the lower edge of the container 40 as shown in FIG. 8A, the load of the contents is always applied to the zipper 20, and the zipper 20 is opened. It becomes easy. When the zipper 20 is formed near the upper edge of the container 50 as shown in FIG. 8B, when the container 50 is tilted, turned upside down, or shaken, the load of the contents is applied to the zipper 20. It becomes easy to start.

  As described above, the container 1 is stably stored, and the fruit liquor is poured out from the spout 10 when the fruit liquor has matured. At the time of pouring, the load due to the load of the contents is applied to the corner portion 4e where the spout 10 is disposed and the upper edge portion 4a in the vicinity of the corner portion 4e, but the zipper 20 is formed on the surface of the sheet-like member. Therefore, the load applied to the zipper 20 is low, and fruit wine does not leak from here.

  And if fruit liquor is poured out and the residual amount becomes lower than the height of the zipper 20, the zipper 20 can be opened and the fruit which became shochu pickled can also be taken out. Moreover, if necessary, fruit and rock sugar can be additionally accommodated from the zipper 20 and shochu can be accommodated from the spout 10 to ripen the fruit liquor again. Furthermore, the container 1 may be shaken when the encapsulated rock sugar is melted to a certain degree or when two or more types of shochu are mixed, but even in such a case, no liquid leaks from the zipper 20. .

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the spirit thereof. For example, regarding the material of the sheet member, various materials can be selected depending on the contents, and the welding method between the sheet members may be ultrasonic welding instead of thermal welding. Further, the shape of the container and the spout, the shape of the zipper and the tear piece are not limited to the above-described embodiment. Further, the formation position and form of the overlapped portion, and the zipper tight-opening structure need not be uneven engagement seals, and the tear pieces are not necessarily required. Furthermore, although food was illustrated as an object to be stored in the above-described embodiment, the present invention is a use in which two or more liquids or solids are mixed and only liquids or solids are taken out. For example, it can be widely used in fields such as pharmaceuticals.
