Hereinafter, embodiments of the present invention will be described. The various features shown in the embodiments shown below can be combined with each other. In addition, the invention is independently established for each feature.

1. 1. First Embodiment The laminated peeling container 1 of the first embodiment of the present invention will be described with reference to FIGS. 1 to 8. The laminated peeling container 1 of the present embodiment includes a container body 3, a cap 4, a valve member 5, and an outer case 6.

<Container body 3, cap 4, valve member 5>
As shown in FIG. 3, the container main body 3 includes an accommodating portion 7 for accommodating the contents and a mouth portion 9 for discharging the contents from the accommodating portion 7. The container body 3 includes an outer shell 12 and an inner bag 14 in the accommodating portion 7 and the mouth portion 9, and the inner bag 14 contracts away from the outer shell 12 as the contents decrease.

A bottom portion 8 is provided at one end of the accommodating portion 7. A shoulder portion 10 is provided between the accommodating portion 7 and the mouth portion 9. The housing portion 7 has a larger outer diameter than the mouth portion 9, and the outer diameter of the shoulder portion 10 is enlarged. The bottom portion 8 is provided with a sealing portion 8a for sealing the outer shell 12 and the inner bag 14, respectively. The seal portion 8a is a seal portion of the laminated parison in blow molding using the laminated parison.

The mouth portion 9 is provided with an engaging portion 9d that can be engaged with the cap 4 having a check valve. The cap 4 may be attached by a plug type or a screw type.

As shown in FIGS. 3 to 4, the accommodating portion 7 is provided with a recess 7a, and the recess 7a is provided with an outside air introduction hole 15. The outside air introduction hole 15 is a through hole provided only in the outer shell 12, and communicates the intermediate space 21 between the outer shell 12 and the inner bag 14 with the outer space S of the container body 3.

As shown in FIGS. 6 to 8, the valve member 5 is provided on the intermediate space 21 side of the shaft portion 5a which is inserted into the outside air introduction hole 15 and can be slidably moved with respect to the outside air introduction hole 15. It also includes a lid portion 5c having a larger cross-sectional area than the shaft portion 5a, and a locking portion 5b provided on the outer space S side of the shaft portion 5a and preventing the valve member 5 from entering the intermediate space 21.

The lid portion 5c is configured to substantially close the outside air introduction hole 15 when the outer shell 12 is compressed, and has a shape in which the cross-sectional area decreases as it approaches the shaft portion 5a. Further, the locking portion 5b is configured so that air can be introduced into the intermediate space 21 when the outer shell 12 is restored after being compressed. When the outer shell 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 to the outside from the outside air introduction hole 15. Due to this pressure difference and the air flow, the lid portion 5c moves toward the outside air introduction hole 15, and the lid portion 5c closes the outside air introduction hole 15. Since the cross-sectional area of the lid portion 5c decreases as it approaches the shaft portion 5a, the lid portion 5c easily fits into the outside air introduction hole 15 and closes the outside air introduction hole 15.

When 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 and the contents in the inner bag 14 are discharged. Further, when the pressing force on the outer shell 12 is released, the outer shell 12 tries to be restored by its own elasticity. At this time, the lid portion 5c is separated from the outside air introduction hole 15, the blockage of the outside air introduction hole 15 is released, and the outside air is introduced into the intermediate space 21. Further, the locking portion 5b is provided with a flow passage 5d so that the locking portion 5b does not block the outside air introduction hole 15, and even when the locking portion 5b is in contact with the outer shell 12, it can be distributed. The outside air can be introduced into the intermediate space 21 through the road 5d and the outside air introduction hole 15.

Next, the layer structure of the container body 3 will be described in more detail. The container body 3 includes an outer shell 12 and an inner bag 14.

The outer shell 12 is composed of, for example, low-density polyethylene, linear low-density polyethylene, high-density polyethylene, polypropylene, an ethylene-propylene copolymer and a mixture thereof. The outer shell 12 is formed to be thicker than the inner bag 14 so as to have high resilience.

The inner bag 14 includes an EVOH layer provided on the outer surface side of the container, an inner surface layer provided on the inner surface side of the container of the EVOH layer, and an adhesive layer provided between the EVOH layer and the inner surface layer. By providing the EVOH layer, the gas barrier property and the peelability from the outer shell 12 can be improved. The adhesive layer may be omitted.

The EVOH layer is a layer made of an ethylene-vinyl alcohol copolymer (EVOH) resin, and is obtained by hydrolysis of an ethylene-vinyl acetate copolymer. The ethylene content of the EVOH resin is, for example, 25 to 50 mol%, preferably 32 mol% or less from the viewpoint of oxygen barrier properties. The lower limit of the ethylene content is not particularly specified, but 25 mol% or more is preferable because the flexibility of the EVOH layer tends to decrease as the ethylene content decreases.

The inner layer is a layer in contact with the contents and is composed of, for example, low density polyethylene, linear low density polyethylene, high density polyethylene, polypropylene, ethylene-propylene copolymer, cycloolefin polymer, EVOH and a mixture thereof. , EVOH is preferable. Barrier properties can be improved by forming a layer in contact with the contents with EVOH.

The adhesive layer is a layer having a function of adhering the EVOH layer and the inner surface layer. For example, an acid-modified polyolefin having a carboxyl group introduced into the above-mentioned polyolefin (eg, maleic anhydride-modified polyethylene) is added, or ethylene acetic acid. It is a vinyl copolymer (EVA). An example of an adhesive layer is a mixture of low density polyethylene or linear low density polyethylene and acid modified polyethylene.

It is assumed that the panel portion 16a1 corresponds to the first region 61 and the other portions correspond to the second region 62, and a pressing force is applied to the panel portion 16a1 to discharge the contents. Therefore, it is preferable to form the panel portion 16a1 with a material softer than other portions. The main body member 16 can be formed by two-color molding.

A bottom wall is not provided on the bottom 8 side of the main body member 16, and the opening 16c matches the shape of the inner surface of the body 16a. The opening 16d is smaller than the opening 16c. The opening 16d is larger than the outer diameter of the mouth portion 9 and smaller than the outer diameter of the shoulder portion 10. Therefore, when the main body member 16 is attached, the upper wall 16b comes into contact with the shoulder portion 10, and the main body member 16 is positioned in the height direction with respect to the container main body 3.

In the main body member 16, the panel portion 16a1 is recessed, and the inner diameter of the main body member 16 in the panel portion 16a1 is smaller than the outer diameter of the accommodating portion 7 at a position higher than the panel portion 16a1. Therefore, the main body member 16 cannot be mounted so as to cover it from the mouth portion 9 side. Therefore, in the present embodiment, as shown in FIG. 13, the main body member 16 is configured by combining a pair of main body constituent members 26.

The main body member 36 includes a body portion 36a, an upper wall 36b, an opening 36c on the bottom 8 side, and an opening 36d on the mouth 9 side. The body portion 36a has a circular cross section on the mouth 9 side and an elliptical cross section on the bottom 8 side. That is, the cross-sectional shape of the body portion 36a gradually changes from a circular shape to an elliptical shape from the mouth portion 9 to the bottom portion 8. Further, the cross-sectional shape of the body portion 36a gradually increases from the mouth portion 9 to the bottom portion 8. A bottom wall is not provided on the bottom 8 side of the main body member 36, and the opening 36c matches the inner surface shape of the body portion 36a on the bottom 8 side. The opening 36d is smaller than the opening 36c. The opening 36d is larger than the outer diameter of the mouth portion 9 and smaller than the outer diameter of the shoulder portion 10. Therefore, when the main body member 36 is attached so as to cover the mouth portion 9 side, the upper wall 36b abuts on the shoulder portion 10 and the main body member 36 is positioned in the height direction with respect to the container main body 3.

The main body member 36 includes a pair of convex portions 36e. The pair of convex portions 36e face each other and project toward the bottom portion 8. A pair of base portions 36f are provided between the pair of convex portions 36e. The pair of bases 36f face each other. The end portion of the main body member 36 on the bottom 8 side has a wavy shape in which the convex portion 36e, the base portion 36f, the convex portion 36e, and the base portion 36f are arranged in this order. The distance between the pair of convex portions 36e is shorter than the distance between the pair of base portions 36f.

As shown in FIG. 20, the convex portion 36e has a width of 80% or more of the total width of the main body member 36 when the convex portion 36e is viewed from the front. In the present embodiment, since the convex portion 36e is provided over the entire width direction of the main body member 36, the convex portion 36e has a width of 100% of the total width of the main body member 36.

The convex portion 36e has an inclined surface 36e1 that is inclined so that the amount of protrusion of the convex portion 36e increases toward the center in the width direction of the main body member 36 when the convex portion 36e is viewed from the front. Therefore, the convex portion 36e has a tapered shape. Further, the tip 36e2 of the convex portion 36e is curved so that the bottom 8 side is convex.

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 has a complementary shape to the end of the main body 36 on the bottom 8 side. The bottom member 37 is not engaged with the main body member 36. Therefore, the end portion of the main body member 36 on the bottom 8 side is free and can be easily deformed.

At the time of use, the contents can be discharged by applying a pressing force to the convex portion 36e.
