Hereinafter, a beverage container, a cup beverage, and the like according to the embodiment of the present invention will be described with reference to the drawings. The perspective view of FIG. 1 shows a schematic configuration of a beverage container P1 and a cup beverage Q1 using the container P1. The beverage container P1 includes a cup-shaped container body 1 having an opening 1a and a lid 2 for heat-sealing the container body 1 so as to cover the opening 1a, and the beverage container P1 has a beverage in the storage space 1s of the container P1. 3 is housed and hermetically packaged to form a cup beverage Q1.

Here, the beverage 3 is assumed to be a cold drink below room temperature (for example, iced coffee, juice, liquor, etc.) that is drunk with a plastic straw, but the beverage 3 is a warm drink above room temperature (for example, hot coffee). , Hot soup, etc.) If there is a certain degree of fluidity, the beverage 3 is not limited to a liquid, but contains a viscous fluid (for example, porridge, liquid food, etc.) and a mixed fluid of a solid and a liquid (for example, tapioca drink, stew, and grain cone). Potage soup, etc.) may be used.

The lid 2 has a laminated structure, and when the lid 2 is peeled off from the container body 1 by holding the opening tab 2t, the lid 2 is partially peeled off from the container body 1 to form a cocoon-shaped drinking spout 2a. To. FIG. 1A shows a state before the lid 2 is peeled off, and FIG. 1B shows a state during the peeling of the lid 2. The outer peripheral portion of the lid 2 and the portion of the drinking spout 2a are separated from the container body 1 by the cuts C0 and C1 shown in FIG. 1 (A). The other parts are separated in the thickness direction of the lid 2 (FIG. 1 (B)), one is peeled from the container body 1 and the other is kept sealed with the container body 1 while covering the opening 1a. To do.

As described above, the container body 1 has a cup shape capable of accommodating the beverage 3 as the content in the internal accommodating space 1s. The container body 1 includes a bottom portion 1b, a side surface portion 1c, and a flange portion 1f as main components, and the bottom portion 1b and the flange portion 1f are connected by the side surface portion 1c. The flange portion 1f is formed so as to project outward from the peripheral edge of the opening 1a for containing the beverage 3, and the lid 2 is heat-sealed with respect to the flange portion 1f.

The cup shape of the container body 1 is a truncated cone shape, and the beverage 3 in the accommodation space 1s is also held in the truncated cone shape. The outer and inner cross-sectional shapes of the flange portion 1f and the side surface portion 1c are circular shapes similar to each other, and the bottom portion 1b is located so as to face the slightly larger opening 1a. The cup shape of the container body 1 is not limited to the truncated cone shape, but may be a truncated cone shape, and the cross-sectional shape is not limited to a perfect circular shape, but may be an elliptical shape, a cocoon shape, a deformed shape thereof, or the like.

The container body 1 is a resin molded body made of a thermoplastic resin such as polypropylene (PP), and is injection molded (for example, PP injection; in-mold molding, in-mold label molding, etc.), vacuum molding (for example, PP multi-layer vacuum molding). ) And the like, the flange portion 1f, the bottom portion 1b, and the side surface portion 1c are integrally and thinly formed (for example, thickness: 0.45 mm). Examples of the material of the container body 1 include PP / EVOH (3%) / PP, PP containing a filler (the filler is composed of an inorganic substance such as lime), and the like (EVOH: ethylene / vinyl alcohol co-weight). Combined).

The lid 2 is made of a laminated film. 2 to 4 schematically show vertical cross sections of three types of laminated configurations as specific examples of the laminated film used for the lid 2. The peeling mechanism of the lid 2 is different for each type, and (A) of FIGS. 2 to 4 shows the state before peeling of the lid 2 in the first to third peeling mechanisms F1 to F3, respectively. (B) of 4 shows the state after peeling of the lid 2 in the first to third peeling mechanisms F1 to F3, respectively. In any type, the lid 2 is made of a laminated film including a base material layer L1, a barrier layer L2, a buffer layer L3, and a multilayer sealant layer (thermosetting resin layer) L4 in this order, and is a flange. The heat seal of the lid 2 with respect to the portion 1f is performed by the multilayer sealant layer L4. Further, the thickness of the entire laminated film of the lid 2 is preferably 60 to 160 μm, and the thickness of the multilayer sealant layer L4 is preferably 40 to 100 μm, but the thickness of the entire laminated film of the lid 2 assumed here is 100 μm. The thickness of the multilayer sealant layer L4 is about 50 μm.

Examples of the base material layer L1 constituting the lid 2 include a laminated structure (for example, PET 12 μm / ONY 15 μm) including PET (polyethylene terephthalate), ONY (biaxially stretched nylon) and the like. Examples of the barrier layer L2 include a material layer having a barrier property (oxygen barrier, etc.) such as an aluminum foil layer and a vapor-deposited film layer. Examples of the buffer layer L3 include a PE (polyethylene) layer formed by extrusion lamination molding, an ONY layer formed by dry lamination molding, and the like. Therefore, specific examples of the laminated structure include PET / AL / AC / extruded PE / L4, PET / AL / DL / ONY / DL / L4 (AL: aluminum foil layer, AC: anchor coat layer, DL). : Adhesive for dry laminating).

The printed layer (not shown) is preferably arranged between the base material layer L1 and the barrier layer L2 or between the barrier layer L2 and the buffer layer L3. However, when the barrier layer L2 is formed by vapor deposition or coating on the base material layer L1, it is preferably arranged between the barrier layer L2 and the buffer layer L3.

The multilayer sealant layer L4 is a cohesive peeling type or delamination type functional film having easy peeling property (easy peeling property) and heat sealing property, and also having appropriate adhesive strength to the buffer layer L3 and the flange portion 1f. (For example, non-stretched coextruded multilayer film). Examples of the multilayer sealant layer L4 include those made of polyethylene and polypropylene (a film having a PE layer and a PP layer, a film having a blend layer of PE and PP, and the like). Specific examples of the multilayer sealant layer L4 of the first peeling mechanism F1 (FIG. 2) and the second peeling mechanism F2 (FIG. 3) include CMPS (registered trademark) -013C and 017C manufactured by Mitsui Chemicals Tocello Corporation; 7601EA, 9501A manufactured by Film Processing Co., Ltd., etc., and CMPS (registered trademark) -302C manufactured by Mitsui Chemicals Tocello Co., Ltd. is mentioned as a specific example of the multilayer sealant layer L4 of the third peeling mechanism F3 (FIG. 4). Be done.

When producing the cup beverage Q1 (FIG. 1), first, the beverage 3 is put into the storage space 1s of the container body 1 from the opening 1a, the lid 2 is arranged on the container body 1 so as to cover the opening 1a, and the flange. While pressing the lid 2 against the portion 1f, the lid 2 is heated at a predetermined temperature (for example, about 150 to 300 ° C.). As described above, the lid 2 is made of a laminated film and has a heat-adhesive multilayer sealant layer L4 on one side. The multi-layer sealant layer L4 heat-seals the lid 2 on the upper surface of the flange portion 1f. By heat-adhering the lid 2 to the flange portion 1f, the beverage 3 is sealed and packaged in the container body 1 to complete the cup beverage Q1.

The multi-layer sealant layer L4 has an easy-peel laminated structure capable of coagulation peeling or delamination inside, and cuts from the multi-layer sealant layer L4 to at least halfway of the buffer layer L3, and C0 and C1 are in a half-cut state. It is formed. Therefore, when the lid 2 is peeled off from the container body 1 by holding the opening tab 2t, the lid 2 is partially peeled off from the container body 1 by cohesive peeling or delamination to form a drinking spout 2a. Therefore, the use of straws is unnecessary. However, it is also important to prevent the lid 2 from being easily peeled off due to transportation of the cup beverage Q1, mischief, or the like. Therefore, the peel strength (temperature condition: normal temperature) assumed here is adjusted by the multilayer sealant layer L4 in the range of 30 to 100 g / 15 mm, preferably 30 to 50 g / 15 mm.

When the lid 2 is peeled off from the container body 1, the outer peripheral portion of the lid 2 and the portion of the drinking spout 2a are separated from the container body 1 by the cuts C0 and C1. The other parts are separated in the thickness direction of the lid 2 as shown in (B) of FIGS. 2 to 4, one of which is peeled from the container body 1 and the other of which covers the opening 1a. The sealed state with 1 is maintained. The thickness of the lid 2 (that is, a part of the multilayer sealant layer L4) remaining on the container body 1 is 20 to 60 μm.

Since the buffer layer L3 is provided between the barrier layer L2 and the multilayer sealant layer L4, it is possible to control the half-cut position so that the cuts C0 and C1 do not reach the barrier layer L2. That is, by forming the cuts C0 and C1 halfway through the buffer layer L3, it is possible to cut the entire multilayer sealant layer L4 without affecting the barrier layer L2. The barrier layer L2 is preferably an aluminum foil layer in order to inspect whether the half-cut state of the cuts C0 and C1 is appropriate.

The multilayer sealant layer L4 constituting the first peeling mechanism F1 (FIG. 2) is composed of a cohesive failure layer L4A, a PE layer L4B, and a PP layer L4C in this order from the buffer layer L3 side to the container body 1 side. In the first peeling mechanism F1, for example, the cohesive fracture layer L4A has a thickness of 10 μm, the PE layer L4B has a thickness of 15 μm, and the PP layer L4C has a thickness of 5 μm.

The multilayer sealant layer L4 constituting the second peeling mechanism F2 (FIG. 3) is composed of a PE layer L4B, a cohesive failure layer L4A, and a PP layer L4C in this order from the buffer layer L3 side to the container body 1 side. For example, the thickness of the PE layer L4B is 20 μm, the thickness of the cohesive fracture layer L4A is 15 μm, and the thickness of the PP layer L4C is 15 μm.

The multilayer sealant layer L4 of the first and second peeling mechanisms F1 and F2 has a cohesive fracture layer L4A, so that it has an easy-peel laminated structure capable of coagulation peeling inside. The cohesive fracture layer L4A is formed by kneading a large amount of small particles made of another material into a specific film material so that cohesive fracture in the layer occurs as a trigger at the boundary. Due to the cohesive fracture generated in the cohesive fracture layer L4A, the lid 2 can be separated at the half-cut cuts C0 and C1.

Examples of the cohesive fracture layer L4A of the first and second peeling mechanisms F1 and F2 include a blend layer of PE and PP. When the amount of PE in the cohesive fracture layer L4A is increased, the buffer layer L3 can be easily formed by extrusion laminating molding using extruded PE. Further, since the PP layer L4C is located on the most side of the container body 1 of the multilayer sealant layer L4, the lid 2 can be adhered to the PP container body 1 with high strength.

The multilayer sealant layer L4 constituting the third peeling mechanism F3 (FIG. 4) is composed of a first PP layer L4D, a PE layer L4E, and a second PP layer L4F in this order from the buffer layer L3 side to the container body 1 side. For example, the thickness of the first PP layer L4D is 20 μm, the thickness of the PE layer L4E is 25 μm, and the thickness of the second PP layer L4F is 5 μm.

The multi-layer sealant layer L4 of the third peeling mechanism F3 has a three-layer structure and constitutes an easy-peel laminated structure capable of internal delamination. The co-extruded PP / PE / PP boundary has a weak adhesive force, and the first PP layer L4D and the PE layer L4E are in a pseudo-adhesive state. That is, by designing the adhesive strength between the layers of the first PP layer L4D and the PE layer L4E to be weaker than the adhesive strength between the PE layer L4E and the second PP layer L4F and the heat seal strength with the container body 1, the first PP Peeling occurs between the layers of the layer L4D and the PE layer L4E. The delamination makes it possible to separate the lid 2 at the half-cut cuts C0 and C1.

Although the delamination can be achieved by coating the layers of the laminated film with a release varnish by printing or the like, the release varnish may come into contact with the beverage 3 through the half-cut cuts C0 and C1. If a coagulation peeling type or delamination type functional film is used, a peeling varnish is not required, so that safety can be ensured.

The plan view of FIGS. 5 to 8 shows the beverage containers P2 to P5 according to the second to fifth embodiments in a state before and after the lid 2 is peeled off. 5 and 8 (A) show the state before the lid 2 is peeled off, and FIGS. 5 to 8 (B) show the state after the lid 2 is peeled off, respectively.

In the beverage container P2 (FIG. 5), the drinking spout 2a is formed at a position different from that of the beverage container P1 (FIG. 1 and the like). That is, in the beverage container P1, the drinking spout 2a is formed closest to the opening tab 2t, whereas in the beverage container P2, the drinking spout 2a is formed farthest from the opening tab 2t. The opening tab 2t provided on the lid 2 serves as a knob when forming the drinking spout 2a by coagulation peeling or delamination as described above. Therefore, when the drinking spout 2a appears at the beginning of peeling the lid 2, the beverage 3 There is a risk of spilling. In the beverage container P2, since the drinking spout 2a does not appear until the lid 2 is almost completely peeled off, care can be taken not to spill the beverage 3.

In the beverage container P1 described above, a half-cut notch C0 is formed in the lid 2 in order to separate the outer peripheral portion of the lid 2. On the other hand, in the beverage container P2, since the notch C0 is not formed in the lid 2, peeling occurs at the position where the strength is the weakest. As a result, by adjusting the peeling strength, it is possible to perform the same peeling as the first to third peeling mechanisms F1 to F3.

In the beverage containers P3 to P5 (FIGS. 6 to 8), three cuts are made from the multilayer sealant layer L4 to at least halfway of the buffer layer L3 so that the intake hole 2b is formed in the lid 2 by coagulation peeling or delamination. C2 is formed in a half-cut state. When the lid 2 is configured so that the intake hole 2b is formed in this way, it becomes easy to exchange the beverage 3 with the outside air in the accommodation space 1s, so that the beverage 3 becomes easy to drink. Further, by making the shape of the drinking spout 2a into a rounded triangle (FIG. 6, FIG. 7) or a quadrangle (FIG. 8), it is possible to obtain the ease of drinking according to the beverage 3.

Beverage containers P3 to P5 are opened because the drinking spout 2a (cut C1) and the intake hole 2b (cut C2) are located side by side along the direction of coagulation peeling or delamination (that is, the opening direction). It can be done efficiently. Further, in the beverage container P3 (FIG. 6), since the drinking port 2a is located between the opening tab 2t and the intake hole 2b (that is, along the opening direction, the opening tab 2t, the drinking port 2a, and the intake air). Since the holes 2b are arranged in this order), the drinking spout 2a is formed before the intake hole 2b. As a result, the mouthpiece 2a can be opened naturally.

In the beverage containers P4 and P5 (FIGS. 7 and 8), since the intake hole 2b is located between the opening tab 2t and the drinking spout 2a (that is, the opening tab 2t and the intake hole are along the opening direction). Since 2b and the drinking spout 2a are arranged in this order), the intake hole 2b is formed before the drinking spout 2a. As a result, the intake hole 2b can be opened without fail, so that it is possible to prevent the beverage 3 from being drunk with only the drinking port 2a opened. In addition, care can be taken not to spill the beverage 3 until the opening is completed, and it is also possible to prevent the beverage 3 from blowing out from the drinking spout 2a by relaxing the pressure difference through the intake hole 2b. When the cup beverage Q1 is microwaved, it is possible to safely remove steam during microwave oven heating by peeling off the lid 2 halfway so that only the intake hole 2b is formed.

In the beverage containers P3 to P5 (FIGS. 6 to 8), 1 to 3 half-cut notches C0 are formed in the lid 2 in order to separate the opening tab 2t side of the outer peripheral portion of the lid 2. By separating only the opening tab 2t side of the outer peripheral portion of the lid 2, the lid 2 can be peeled off with a small force. Further, by forming a plurality of notches C0, it is possible to reduce peeling mistakes.

According to each of the above embodiments, as described above, in the lid 2 made of a laminated film in which a half-cut notch C1 is formed, a drinking spout 2a is formed in the lid 2 by agglomeration peeling or delamination peeling of the multilayer sealant layer L4. This eliminates the need for plastic straws and vacuum-formed lids. Therefore, it is possible to realize beverage containers P1 to P5 and cup beverage Q1 having a drinking spout 2a in which the amount of plastic used is significantly reduced.
