DETAILED DESCRIPTION

[0082] The following describes the embodiments of the present invention. The various features described in the embodiments described below can be combined with each other. In addition, each feature can independently establish the present invention.

[0083] 1. First Implementation Method like Figures 1 to 9 As shown in FIG. 1 , a laminated peelable container (storage container) 1 according to a first embodiment of the present invention includes an outer box (outer container) 2, a container body (inner container) 3, a pump 4, and a fixing ring 5. The outer box 2 stores the container body 3 therein.

[0084] <External box 2> The outer box 2 is a bottomed cylindrical shape, and is provided with a main body 2a and a bottom 2b. A reduced diameter portion 2c is provided on the outer side of the upper end of the main body 2a, and the outer diameter of the main body 2a is reduced. An external thread portion 2f is provided on the reduced diameter portion 2c. A support portion 2d for supporting the flange portion 3c of the container body 3 is provided on the inner side near the upper end of the main body 2a. The support portion 2d is formed with the inner diameter of the main body 2a becoming larger near the upper end. In other words, the side above the support portion 2d is formed as an enlarged diameter portion 2g larger than the inner diameter of the main body 2a below the support portion 2d, and a step is formed on the support portion 2d. An external air circulation portion 2e is provided on the support portion 2d and the enlarged diameter portion 2g, so that the external air can be circulated through the external air circulation portion 2e when the container body 3 is installed in the outer box 2. The bottom 2b is flat, and the outer box 2 is capable of standing. The manufacturing method and material of the outer box 2 are not particularly limited, but it is preferably a resin box formed by injection molding, for example.

[0085] <Container body 3> The container body 3 is a laminated peelable container having an outer shell 12 and an inner bag 14, and the inner bag 14 shrinks as the content decreases. As the inner bag 14 separates from the outer shell 12 as the content decreases, the inner bag 14 separates from the outer shell 12 and shrinks.

[0086] The housing 12 is made of, for example, low-density polyethylene, linear low-density polyethylene, high-density polyethylene, polypropylene, ethylene-propylene copolymer, or a mixture thereof.

[0087] The inner bag 14 includes an EVOH layer disposed on the outer surface of the container, an inner layer disposed on the inner surface of the container of the EVOH layer, and an adhesive layer disposed between the EVOH layer and the inner layer. The EVOH layer can improve gas barrier properties and peelability from the outer shell 12. The adhesive layer can also be omitted.

[0088] The EVOH layer is a layer composed of an ethylene-vinyl alcohol copolymer (EVOH) resin, which can be obtained by hydrolysis of an ethylene-vinyl acetate copolymer. The ethylene content of the EVOH resin is, for example, 25 to 50 mol%, and is preferably 32 mol% or less from the viewpoint of oxygen barrier properties. The lower limit of the ethylene content is not particularly limited, but the lower the ethylene content, the more likely the softness of the EVOH layer is to decrease, so it is preferably 25 mol% or more.

[0089] The inner layer is a layer in contact with the contents, and may be composed of, for example, low-density polyethylene, linear low-density polyethylene, high-density polyethylene, polypropylene, ethylene-propylene copolymer, cycloolefin polymer, EVOH, and mixtures thereof, preferably EVOH. By forming a layer in contact with the contents with EVOH, the barrier properties can be improved.

[0090] The adhesive layer is a layer having the function of bonding the EVOH layer and the inner surface layer, and can be, for example, a layer of an acid-modified polyolefin (e.g., maleic anhydride-modified polyethylene) added to the polyolefin as described above to introduce a carboxyl group, or an ethylene-vinyl acetate copolymer (EVA). An example of the adhesive layer is a mixture of low-density polyethylene or linear low-density polyethylene and acid-modified polyethylene.

[0091] The container body 3 is a bottomed cylindrical shape, and is provided with a main body 3a, a bottom 3b, a flange 3c, and a mouth 3d. The flange 3c is arranged at the upper end of the main body 3a. The flange 3c is arranged to protrude radially outward from the main body 3a. The outer diameter of the flange 3c is substantially the same as the expanded diameter portion 2g. If the container body 3 is inserted into the outer box 2, the lower surface of the flange 3c abuts against the support portion 2d, thereby fixing the container body 3 in a position relative to the upper and lower directions of the outer box 2. In other words, the flange 3c is supported by the outer box 2. In addition, the outer peripheral surface of the flange 3c fixes the container body 3 in a horizontal position relative to the outer box 2 by abutting against the inner peripheral surface of the expanded diameter portion 2g. When the flange 3c is in close contact with the expanded diameter portion 2g and the support portion 2d, although it becomes difficult to introduce external air into the gap between the outer box 2 and the container body 3, in this embodiment, external air can be circulated through the external air circulation portion 2e. The flange portion 3c is hollow, and contents can be accommodated in the flange portion 3c.

[0092] A main body gap 18 is provided between the main body 3a of the container body 3 and the main body 2a of the outer box 2. With such a gap, the thermal insulation is further improved. Let the thickness of the outer shell 12 be Ts, and the thickness of the main body gap 18 be Tg, preferably Tg / Ts≥0.3, and more preferably Tg / Ts≥0.5. In this case, the thermal insulation can be particularly improved without thickening the outer shell 12. Tg / Ts is, for example, 0.3 to 100, and more specifically, it can be, for example, 0.3, 0.5, 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, or a value within the range between any two values ​​exemplified here. Let the volume of the container body 3 be V1, and the volume of the outer box 2 be V2, preferably V1 / V2≤0.99, and more preferably V1 / V2≤0.90. V1 / V2 is, for example, 0.1 to 0.95, more specifically, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 0.95, 0.99, or a value within the range between any two values ​​exemplified herein.

[0093] A bottom gap 19 is provided between the bottom 3b of the container body 3 and the bottom 2b of the outer box 2. The inner bag 14 has an inner bag exposed portion 14a exposed to the outside on the bottom 3b side. In the present embodiment, the inner bag exposed portion 14a protrudes from the bottom 3b, but the inner bag exposed portion 14a may not protrude from the bottom 3b. The inner bag exposed portion 14a is clamped by the clamping portion 12a of the outer shell 12, and an external air introduction hole 15 is provided between the inner bag exposed portion 14a and the clamping portion 12a. A gap is also provided between the inner bag exposed portion 14a and the front end of the clamping portion 12a and the bottom 2b of the outer box 2. When the inner bag 14 shrinks as the contents are discharged, external air is introduced between the inner bag 14 and the outer shell 12 through the external air introduction hole 15. In this way, only the inner bag 14 shrinks, and the outer shell 12 maintains its original shape, thereby forming a gap between the inner bag 14 and the outer shell 12. Such a gap can improve the thermal insulation of the laminated peeling container, thereby suppressing the deterioration of the contents.

[0094] In one example, the container body 3 may be formed by blow molding a cylindrical laminated parison. The inner bag exposed portion 14a and the clamping portion 12a may be formed by deforming the lower end of the laminated parison by clamping the clamping portion of the split mold. After the container body 3 is formed, the inner bag exposed portion 14a and the clamping portion 12a are adhered together and the external air inlet hole 15 cannot be provided, but the inner bag exposed portion 14a and the clamping portion 12a are easy to peel off, so by applying an impact force or torsion force that causes the inner bag exposed portion 14a and the clamping portion 12a to be peeled off, the inner bag exposed portion 14a and the clamping portion 12a can be peeled off and the external air inlet hole 15 can be formed therebetween.

[0095] The container body 3 has a mouth portion 3d, and an external thread portion 3e is provided on the outer surface of the mouth portion 3d.

[0096] The container body 3 can be decorated, for example, by covering with a shrink film. By designing the outer box 2 to be transparent, the decoration of the container body 3 can be seen from the outside.

[0097] <Pump 4> The pump 4 is configured to discharge the contents from the container body 3 without introducing external air into the container body 3. The pump 4 includes a main body 4a, a piston 4b, a nozzle 4c, and a straw 4d. The main body 4a includes a barrel 4a1, a cylindrical portion 4a2, and an upper wall 4a3. An internal thread 4a4 that is screwed with the external thread 3e is provided on the inner surface of the barrel 4a1. The cylindrical portion 4a2 is inserted into the mouth 3d. The outer diameter of the cylindrical portion 4a2 is substantially consistent with the inner diameter of the mouth 3d. The cylindrical portion 4a2 is cylindrical, and the piston 4b can slide in the cylindrical portion 4a2. The internal space of the cylindrical portion 4a2 is connected to the nozzle 4c and the straw 4d. A pump structure composed of an elastic member and a valve is hidden in the internal space of the cylindrical portion 4a2. The pump structure is operated by sliding the piston 4b, so that the contents sucked up by the straw 4d can be discharged from the nozzle 4c.

[0098] <Fix ring 5> The fixing ring 5 includes an outer cylinder 5a, an upper wall 5b, and an inner cylinder 5d. The outer cylinder 5a and the inner cylinder 5d are connected by the upper wall 5b. An inner thread 5f that can be screwed with the outer thread 2f is provided on the inner surface of the outer cylinder 5a. An opening 5c ​​is provided at the upper wall 5b. The inner diameter of the opening 5c ​​is larger than the outer diameter of the cylinder 4a2. Figure 1 As shown, when the pump 4 is mounted on the mouth 3d and the fixing ring 5 is mounted on the outer box 2, a gap is formed between the outer surface of the barrel 4a1 of the pump 4 and the inner surface of the opening 5c, so that ventilation is possible. In addition, when the fixing ring 5 is mounted on the outer box 2 in the state where the container body 3 is inserted into the outer box 2, since the front end of the inner barrel 5d abuts against the upper surface 3f of the container body 3, the container body 3 can be completely fixed in the up and down direction. It should be pointed out that at the flange 3c of the container body 3, the container body 3 is concave and convexly engaged with the outer box 2, so even if the fixing ring 5 is not provided, the container body 3 can be fixed relative to the outer box 2. When the inner barrel 5d is in close contact with the upper surface 3f, although it is not easy to introduce external air into the gap between the outer box 2 and the container body 3, in this embodiment, since the outer air circulation portion 5e is provided in the inner barrel 5d, the outer air passing through the outer air circulation portion 5e can be circulated.

[0099] In the structure of this embodiment, the outside air is introduced into the gap between the inner bag 14 and the outer shell 12 through the opening 5c, the outside air passing parts 5e, 2e, the main body gap 18, the bottom gap 19 and the outside air introduction hole 15. Therefore, even when the laminated and peelable container 1 is suddenly exposed to a high temperature environment, the high-temperature outside air is unlikely to contact the inner bag 14.

[0100] <Manufacturing and usage> The laminated peelable container 1 of this embodiment can be manufactured as follows: after the container body 3 is filled with the content, the pump 4 is installed at the mouth 3d and then inserted into the outer box 2, and the fixing ring 5 is installed on the outer box 2 in this state.

[0101] The contents can be Figure 2 As shown in the figure, the inner bag 14 is completely filled so that there is no gap between the inner bag 14 and the outer shell 12, or it can be as shown in the figure. Fig. 9 The filling is shown in a manner that a gap is provided between the inner bag 14 and the outer shell 12 (that is, partially filled). In this case, after the contents are filled and before the user starts to discharge the contents, there is a gap between the inner bag 14 and the outer shell 12, so that the thermal insulation can be further improved. When the volume of the outer shell 12 is Vs, and the volume of the contents accommodated in the inner bag 14 is Vc, preferably Vc / Vs≤0.95, more preferably Vc / Vs≤0.9. Vc / Vs is, for example, 0.5 to 0.95, and more specifically, it can be, for example, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, or a value within the range between any two values ​​exemplified here.

[0102] As a method of partially filling the contents, for example, the air in the inner bag 14 is sucked out from the mouth 3d, the inner bag 14 is peeled off from the outer shell 12, and the inner bag 14 is contracted, and then partially filled with the contents. In this method, a gap can be provided between the inner bag 14 and the outer shell 12, and the inner bag 14 can be partially filled without leaving air in the inner bag 14.

[0103] 2. Second Implementation Method use Fig.10 The second embodiment of the present invention will be described. The basic configuration and function of this embodiment are the same as those of the first embodiment, and the main difference is that the shapes of the components are different from those of the first embodiment. The following description will focus on the differences.

[0104] In this embodiment, the outer diameter of the container body 3 is smaller than that of the first embodiment, and the outer box 2 expands near the bottom 2b. As a result, the main body gap 18 becomes very large, thereby improving the thermal insulation. In addition, in this embodiment, although the outside air is introduced into the space between the inner bag 14 and the outer shell 12 from the outside air introduction hole 15 provided at the bottom 3b, in this embodiment, the inner bag 14 and the outer shell 12 do not protrude at the bottom 3b of the container body 3, which is different from the first embodiment. Therefore, the flow of the outside air between the bottom 2b and the bottom 3b becomes smooth.

[0105] 3. Third Implementation Method use Figure 11 to Figure 13 The third embodiment of the present invention is described. The basic structure and function of this embodiment are the same as those of the first embodiment, but the main difference is that the outer box 2 and the container body 3 are mounted on the fixing ring 5, and the pump 4 is also mounted on the fixing ring 5. The following is a description focusing on the differences.

[0106] In this embodiment, the fixing ring 5 has an external air introduction hole 5h, a protrusion 5i, a recess 5j, and a cylinder 5k having an internal thread 51 in addition to the configuration of the first embodiment. The pump 4 does not have a cylinder 4a1 but has a flange 4a5. The flange 4a5 protrudes radially outward from the cylinder 4a1.

[0107] The external air introduction hole 5h is formed on the upper wall portion 5b. The protrusion 5i is formed at the center of the upper wall portion 5b. The protrusion 5i can be omitted. The recess 5j is formed in the protrusion 5i. The size of the opening 5c ​​is such that the cylindrical portion 4a2 can be inserted but the flange portion 4a5 cannot be inserted. The recess 5j is configured to be able to engage with the flange portion 4a5. The cylinder portion 5k having the internal thread portion 5l is configured in the same manner as the cylinder portion 4a1 having the internal thread portion 4a4 of the first embodiment.

[0108] With such a structure, both the container body 3 and the outer box 2 can be mounted (fixed by screws) on the fixing ring 5. The pump 4 can also be mounted on the fixing ring 5. The pump 4 can be detachable from the fixing ring 5 or can be formed integrally with the fixing ring 5.

[0109] In the first embodiment, it is assumed that the outside air is introduced into the outer box 2 from the gap between the pump 4 and the fixing ring 5, but in this embodiment, the outside air is introduced into the outer box 2 from the pinhole-shaped outside air introduction hole 5h. The outside air introduction hole 5h may be provided at other positions.

[0110] 4. Fourth Implementation Method use Figure 14 to Figure 16The fourth embodiment of the present invention is described. The basic structure and function of this embodiment are the same as those of the first embodiment, but the main difference is the formation of the outer box 2, the container body 3 and the fixing ring 5. The following description will be centered on the differences.

[0111] In the present embodiment, the flange portion 3c comprises an annular portion 3c1 and a protrusion 3c2. The protrusion 3c2 protrudes radially outward from the annular portion 3c1. A plurality of protrusions 3c2 are arranged at intervals along the circumferential direction (two in the present embodiment). A notch portion 2h is provided at the upper end of the outer box 2. The notch portion 2h is in a shape complementary to the protrusion 3c2. When the container body 3 is accommodated in the outer box 2 and the protrusion 3c2 is engaged with the notch portion 2h, the container body 3 is fixed in a position relative to the outer box 2 along the circumferential direction. At this time, the annular portion 3c1 is not supported by the outer box 2.

[0112] An annular recess 2i is provided on the reduced diameter portion 2c of the outer box 2. An annular protrusion 5g is provided on the inner circumference of the fixing ring 5. When the reduced diameter portion 2c is inserted into the fixing ring 5, the annular recess 2i engages with the annular protrusion 5g, so that the fixing ring 5 is fixed to the outer box 2.

[0113] 5. Contents of the Viewpoints of the Fifth to Seventh Embodiments (Prior Art) There is known a laminated peelable container in which an inner bag shrinks as the content decreases to thereby suppress the entry of air into the container (for example, Patent Document 2).

[0114] (Topic) The laminated peelable container in Patent Document 2 is configured by covering a container body housing portion formed by blow molding with a shrink film, but there is a need for a more high-end appearance.

[0115] The present invention has been made in view of the above circumstances, and provides a peelable laminate container which has a high degree of freedom in appearance design and can discharge the contents by applying a compressive force.

[0116] (Solution) According to the present invention, a stacking peeling container is provided, which comprises a container body and a cylindrical outer box installed on the container body, wherein the container body comprises a receiving portion for receiving contents and a mouth portion for discharging the contents from the receiving portion; the container body comprises an outer shell and an inner bag, and is configured so that the inner bag shrinks as the contents decrease; the outer box is installed to cover at least a portion of the receiving portion, and the stacking peeling container is configured so that the outer box can be deformed so that the contents can be discharged from the mouth portion.

[0117] In the laminated peeling container of the present invention, since at least a part of the receiving portion is covered by the cylindrical outer box, the freedom of the appearance design of the container is high. In addition, by selecting an outer box with excellent appearance, the appearance can be made to have a high-end feel. In addition, when an outer box that is not easily deformed is used, the contents cannot be discharged by applying a squeezing force to the container, but in the present invention, because a deformable outer box is used, the outer box is deformed together with the container body, so that the contents can be discharged even if the outer box is installed.

[0118] 6. Fifth Implementation Method use Figures 17 to 24 A separable laminated container 1 according to a fifth embodiment of the present invention will be described. The separable laminated container 1 according to the present embodiment includes a container body 3 , a lid 4 e , a valve member 11 , and an outer box 6 .

[0119] <Container body 3, lid 4e, valve member 11> like Fig.19 As shown, the container body 3 includes a receiving portion 7 for receiving the contents and a mouth 9 for discharging the contents from the receiving portion 7. The container body 3 includes an outer shell 12 and an inner bag 14 at the receiving portion 7 and the mouth 9, and the inner bag 14 separates from the outer shell 12 and shrinks as the contents decrease.

[0120] A bottom portion 8 is provided at one end of the housing portion 7. A shoulder portion 10 is provided between the housing portion 7 and the mouth portion 9. The outer diameter of the housing portion 7 is larger than that of the mouth portion 9, and the outer diameter becomes larger at the shoulder portion 10. A sealing portion 8a for sealing the outer shell 12 and the inner bag 14 is provided at the bottom portion 8. The sealing portion 8a is a sealing portion of the laminated parison in the blow molding process using the laminated parison.

[0121] The mouth portion 9 is provided with an engaging portion 9d capable of engaging with a cap 4e equipped with a check valve. The cap 4e may be mounted by a gland type or a threaded type.

[0122] like Figure 19-20 As shown, the housing portion 7 is provided with a recess 7a, and the recess 7a is provided with an external air introduction hole 15. The external air introduction hole 15 is a through hole provided only on the outer shell 12, and connects the intermediate space 21 between the outer shell 12 and the inner bag 14 with the external space S of the container body 3.

[0123] like Figure 22 to Figure 24 As shown, the valve component 11 is inserted into the external air inlet hole 15, and comprises a shaft portion 11a which can slide relative to the external air inlet hole 15, a cover portion 11c which is arranged on the intermediate space 21 side of the shaft portion 11a and has a larger cross-sectional area than the shaft portion 11a, and a locking portion 11b which is arranged on the external space S side of the shaft portion 11a and prevents the valve component 11 from entering the intermediate space 21.

[0124] The cover 11c is configured to substantially close the external air inlet hole 15 when the housing 12 is compressed, and the cross-sectional area thereof decreases as it gradually approaches the shaft 11a. In addition, the stopper 11b is configured to be able to introduce air into the intermediate space 21 when the housing 12 is restored after being compressed. When the housing 12 is compressed, the pressure in the intermediate space 21 becomes higher than the external pressure, and the air in the intermediate space 21 leaks out from the external air inlet hole 15 to the outside. Due to this pressure difference and air flow, the cover 11c moves toward the external air inlet hole 15, so that the cover 11c blocks and closes the external air inlet hole 15. Since the cover 11c is configured to have a cross-sectional area that decreases as it approaches the shaft 11a, the cover 11c is easily stuck in the external air inlet hole 15 to block and close the external air inlet hole 15.

[0125] If the outer shell 12 is further compressed in this state, the pressure in the intermediate space 21 increases, and as a result, the inner bag 14 is compressed so that the contents in the inner bag 14 are discharged. In addition, when the squeezing force on the outer shell 12 is released, the outer shell 12 attempts to restore its original state by its own elasticity. At this time, the cover 11c is separated from the external air introduction hole 15, and the closure of the external air introduction hole 15 is released, thereby introducing external air into the intermediate space 21. In addition, in order to prevent the stopper 11b from blocking the external air introduction hole 15, a flow portion 11d is provided on the stopper 11b, so that even when the stopper 11b is in contact with the outer shell 12, the external air can be introduced into the intermediate space 21 through the flow portion 11d and the external air introduction hole 15.

[0126] Next, the layer structure of the container body 3 is described in more detail. The container body 3 includes an outer shell 12 and an inner bag 14. The outer shell 12 is formed thicker than the inner bag 14 to improve the recovery property. The layer structure and materials of the outer shell 12 and the inner bag 14 are as described in the first embodiment.

[0127] <External box 6> The outer box 6 is cylindrical and is installed to cover at least a part of the receiving portion 7. The outer box 6 includes a main body 6a, an upper wall 6b, an opening 6c on the side of the bottom 8, and an opening 6d on the side of the mouth 9. The main body 6a is substantially cylindrical and has a substantially constant cross section in the height direction of the receiving portion 7. The receiving portion 7 is reduced in diameter near the central position CP in the height direction of the receiving portion 7, as shown in FIG. Fig. 22 As shown, a gap 22 is provided between the storage part 7 and the outer box 6. The thermal insulation performance of the laminated peeling container 1 is improved by this gap 22. On the other hand, the storage part 7 abuts against the outer box 6 at a position P1 lower than the central position CP and a position P2 higher than the central position CP.

[0128] No bottom wall is provided on the bottom 8 side of the outer box 6, and the opening 6c is consistent with the inner surface shape of the main body 6a. The opening 6d is smaller than the opening 6c. The opening 6d is larger than the outer diameter of the mouth 9 and smaller than the outer diameter of the shoulder 10. Therefore, when the outer box 6 is installed to cover the mouth 9 side, the upper wall 6b abuts against the shoulder 10, so that the outer box 6 is fixed in a position in the height direction relative to the container body 3.

[0129] like Figure 19-20 As shown, the upper wall 6b is disposed between the cover 4e and the shoulder 10. Therefore, when the cover 4e is tightened, the upper wall 6b is clamped and fixed by the cover 4e and the shoulder 10.

[0130] The outer box 6 is formed of a thickness and material that can be easily deformed. When the outer box 6 is installed in the container body 3, it can be deformed by applying a squeezing force to the outer box 6 to compress the inner bag 14 through the outer shell 12 and the intermediate space 21 to discharge the contents of the inner bag 14.

[0131] The outer box 6 preferably has an appropriate restoring force, and when the pressing force is released after the outer box 6 is deformed by applying a compressive force, it is restored to its original shape by the restoring force of the outer box 6. In this case, the outer box 6 can be repeatedly deformed and the contents can be repeatedly discharged.

[0132] More specifically, the outer box 6 is preferably configured such that the maximum value of the amount of indentation when a 2kg extrusion force is applied using a 15mm diameter pressure head is 5mm or more. In this case, since the outer box 6 is easily deformed, it is easy to discharge the contents. The so-called maximum value of the indentation refers to the maximum value obtained by measuring the indentation amount at each part of the outer box 6, which is equivalent to the indentation amount at the position most easily pressed into the outer box 6. The maximum value is, for example, 5 to 40mm, more specifically, it can be, for example, 5, 10, 15, 20, 25, 30, 35, 40mm, or a value within the range between any two values ​​​​exemplified here. In addition, (the maximum value of the indentation amount) / (the diameter of the receiving portion 7) is preferably 0.1 or more, for example, 0.1 to 0.7, more specifically, it can be, for example, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, or a value within the range between any two values ​​​​exemplified here.

[0133] The outer box 6 is preferably configured so that the maximum value of the amount of pressure at the portion opposite to the center in the height direction of the receiving portion 7 is the above value. When the contents are discharged, the portion near the center in the height direction of the receiving portion 7 is often squeezed, so it is preferred that the outer box 6 is easily deformed at this portion.

[0134] The material of the outer box 6 is not limited as long as it can be deformed when a compressive force is applied to the outer box 6. The outer box 6 is, for example, an injection molded body. By forming the outer box 6 by injection molding, its appearance can be improved.

[0135] The thickness of the outer box 6 is preferably 0.2 mm or more, more preferably 0.5 mm or more. This thickness can be, for example, 0.2 to 3 mm, more specifically, can be, for example, 0.2, 0.5, 1, 1.5, 2, 2.5, 3 mm, or a value within the range between any two values ​​exemplified herein.

[0136] The outer box 6 includes a first area 61 and a second area 62. The first area 61 is arranged at a position opposite to the center of the storage portion 7 in the height direction. Since it is assumed that a pressing force is applied to the first area 61 to discharge the contents, it is preferred that the outer box 6 is easily deformed in the first area 61, and it is preferred that the maximum value of the pressing amount in the first area 61 is the above value.

[0137] Preferably, the first area 61 is formed by a first material (soft material) having a lower bending modulus than the second material constituting the second area 62, so that the outer box 6 is easily deformed in the first area 61. This outer box 6 can be formed by two-color molding or embedded molding. As the first material, elastomers (olefin elastomers, styrene elastomers, etc., natural rubber, synthetic rubber (silicone, etc.), EVA, low-density polyethylene, soft polyvinyl chloride, or materials formed by lamination of these materials can be listed. As the second material, resin materials (high-density polyethylene, polypropylene, PET, acrylic resin, nylon resin, ABS resin, hard polyvinyl chloride, polystyrene, and fiber), wood, metal, glass, ceramics, or materials formed by lamination of materials can be listed.

[0138] In addition, the thickness of the first region 61 may be made thinner than that of the second region 62 so that the outer box 6 can be easily deformed in the first region 61. In this case, the thickness of the first region 61 / the thickness of the second region 62 is preferably less than 0.95. This thickness may be, for example, 0.3 to 0.95, more specifically, it may be, for example, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, or a value within the range between any two values ​​exemplified here.

[0139] In order to further improve the outer box 6, the outer surface may be decorated.

[0140] 7. Sixth Implementation Method use Figure 25 to Figure 29A laminated and separable container 1 according to a sixth embodiment of the present invention will be described. The structure of the outer box 6 of this embodiment is different from that of the fifth embodiment. The structure of the container body 3, the lid 4e, and the valve member 11 are the same as those of the fifth embodiment.

[0141] In the present embodiment, the outer box 6 includes a main body member 16 and a bottom member 17. The main body member 16 is disposed at a position closer to the mouth portion 9 than the bottom member 17 is.

[0142] The main body part 16 includes a main body part 16a, an upper wall 16b, an opening part 16c on the side of the bottom 8, and an opening part 16d on the side of the mouth 9. The main body part 16a is provided with a panel part 16a1 formed by the main body part 16a being recessed. Assuming that the panel part 16a1 is equivalent to the first area 61 and the other parts are equivalent to the second area 62, a squeezing force is applied to the panel part 16a1 to discharge the contents. Therefore, it is preferable to form the panel part 16a1 with a material softer than other parts. The main body part 16 can be formed by two-color molding.

[0143] No bottom wall is provided on the bottom 8 side of the body member 16, and the opening 16c is consistent with the inner surface shape of the main body 16a. The opening 16d is smaller than the opening 16c. The opening 16d is larger than the outer diameter of the mouth 9 and smaller than the outer diameter of the shoulder 10. Therefore, when the body member 16 is installed, the upper wall 16b abuts against the shoulder 10, so that the body member 16 is fixed in a position in the height direction relative to the container body 3.

[0144] In the body part 16, the panel part 16a1 is recessed, and the inner diameter of the body part 16 at the panel part 16a1 is smaller than the outer diameter of the receiving part 7 at a position higher than the panel part 16a1. Therefore, the body part 16 cannot be installed to cover the mouth part 9 side. Fig.29 As shown, it is composed by combining a pair of body structural members 26. The pair of body structural members 26 are preferably of the same shape.

[0145] A reduced diameter portion 26f is provided at the lower end of the body member 16, and an annular protrusion 26g protruding radially outward is provided at the reduced diameter portion 26f. In addition, an annular protrusion 17a protruding radially inward is provided near the upper end of the bottom member 17. The reduced diameter portion 26f is inserted into the bottom member 17, so that the protrusion 26g and the protrusion 17a are engaged. In this way, the body member 16 and the bottom member 17 are engaged, thereby forming an integrated outer box 6.

[0146] 8. Seventh Implementation Method use Figure 30 to Figure 32A seventh embodiment of the present invention is described with respect to a delamination container 1. This embodiment is similar to the fifth embodiment, but the main differences are the shape of the container body 3 and the first region 61. The following description will focus on the differences.

[0147] The container body 3 of this embodiment has Fig.31 The shape shown in the figure, but its basic structure and function are the same as those of the fifth embodiment. In this embodiment, the first area 61 is arranged in the entire circumferential direction. With such a structure, the contents can be discharged by squeezing any position in the circumferential direction near the center of the height direction of the receiving portion 7.

[0148] 9. 8th Implementation Method use Figure 33 to Figure 36 The eighth embodiment of the present invention is described below with respect to the laminated and peelable container 1. This embodiment is similar to the seventh embodiment, but the main difference is the configuration of the outer box 6. The following description will be centered around the differences.

[0149] The structure of the container body 3 of this embodiment is the same as that of the seventh embodiment. The outer box 6 includes a body member 36 and a bottom member 37. The body member 36 is arranged closer to the mouth 9 than the bottom member 37. The body member 36 and the bottom member 37 can be formed by injection molding.

[0150] The body member 36 includes a body portion 36a, an upper wall 36b, an opening portion 36c on the bottom 8 side, and an opening portion 36d on the mouth 9 side. The cross section of the body portion 36a on the mouth 9 side is circular, and the cross section on the bottom 8 side is elliptical. That is, the cross-sectional shape of the body portion 36a gradually changes from a circular shape to an elliptical shape from the mouth 9 to the bottom 8. In addition, the cross-sectional shape of the body portion 36a gradually increases from the mouth 9 to the bottom 8. No bottom wall is provided on the bottom 8 side of the body member 36, and the opening portion 36c is consistent with the inner surface shape of the body portion 36a on the bottom 8 side. The opening portion 36d is smaller than the opening portion 36c. The opening portion 36d is larger than the outer diameter of the mouth 9 and smaller than the outer diameter of the shoulder 10. Therefore, when the body member 36 is installed in a manner of covering from the mouth 9 side, the upper wall 36b abuts against the shoulder 10, and the body member 36 is fixed at a position in the height direction relative to the container body 3.

[0151] The main body part 36 has a pair of convex parts 36e. The pair of convex parts 36e are opposite to each other and protrude toward the bottom 8. A pair of base parts 36f are provided between the pair of convex parts 36e. The pair of base parts 36f are opposite to each other. The end of the bottom 8 side of the main body part 36 is arranged in the order of convex part 36e, base part 36f, convex part 36e, and base part 36f, and is wavy. The distance between the pair of convex parts 36e is shorter than the distance between the pair of base parts 36f.

[0152] like Fig.36 As shown, the convex portion 36e has a width of more than 80% of the entire width of the body member 36 when the convex portion 36e is viewed from the front. In this embodiment, since the convex portion 36e is provided in the entire width direction of the body member 36, it has a width of 100% of the entire width of the body member 36.

[0153] The convex portion 36e has an inclined surface 36e1 which is inclined so that the protrusion amount of the convex portion 36e becomes larger toward the center of the width direction of the body member 36 when the convex portion 36e is viewed from the front. Therefore, the convex portion 36e has a tapered shape. In addition, the front end 36e2 of the convex portion 36e is curved so that the bottom 8 side is convex.

[0154] The bottom member 37 is fixed to the bottom 8 of the container body 3. The end of the bottom member 37 on the mouth 9 side is complementary to the end of the bottom 8 side of the body member 36. The bottom member 37 is not engaged with the body member 36. Therefore, the end of the bottom 8 side of the body member 36 is movable and can be easily deformed.

[0155] When in use, the contents can be discharged by applying a squeezing force to the convex portion 36e.

[0156] 10. Other Implementation Methods In the fifth and sixth embodiments, the pair of first regions 61 are provided so as to face each other, but the first region 61 may be provided at only one location.

[0157] In the sixth and eighth embodiments, the bottom member may be omitted.

[0158] Instead of the method of clamping and fixing the cover 4 e and the shoulder 10 , other structures may be used to fix the outer box 6 to the container body 3 .

[0159] Instead of providing several regions of different materials, the entire outer case 6 may be formed of a soft material.

[0160] When a pressing force is applied to the outer box 6, the valve member 11 blocks and closes the external air introduction hole 15. Other structures may be used as long as the valve member 11 has a function of opening the external air introduction hole 15 when the pressing force is removed.

[0161] The second region 62 may be formed of a non-resin material such as metal or ceramic.

[0162] In the eighth embodiment, the main body member 36 and the bottom member 37 may be engaged with each other at the base portion 36f.

[0163] Instead of embedding the check valve in the cover 4 e , a check valve of another component may be disposed between the cover 4 e and the container body 3 .
