SUMMARY OF THE INVENTION

Technical problem

Known packaging capacity described above has the following disadvantages. Namely, the packaging container described above is made of paper material, the continuous portion of which between the tank and the lid serves as a hinge for turning the lid. The hinge is a creased line, or an extruded recess or notch visible on an open packaging container. Recesses or notches are provided by pressing paper material in the manufacture of a packaging container. Therefore, if the lid is not held after turning around the hinge, the lid tends to rotate in the closing direction due to the elasticity of the hinge.

Therefore, it is preferable for the user to hold the lid after rotation to remove the packaging object from the tank. However, in the case when, for example, the hands of the user are busy, it is sometimes impossible to hold the lid. Thus, there is a need for a packaging container that can hold the lid rotated, that is, keep the opening of the tank open without holding the lid after turning the lid.

Accordingly, an object of the present invention is to provide a packaging container that can easily keep an opening of a tank open.

The solution of the problem

To solve the above problems and achieve the objective, the packaging container of the present invention is made as described below.

According to one aspect of the present invention, there is provided a packaging container comprising a reservoir holding a packaging object and open at the top; a cap covering the opening of the tank; and a hinge connecting the reservoir with the lid, so that the reservoir and the lid are integral with each other and so that the lid can be rotated relative to the specified reservoir, while the specified reservoir and the lid contain engaging portions that mesh with each other to regulate the movement of the lid, rotated around the hinge in the direction of travel from the tank.

The technical result of the invention

The present invention provides a packaging container that can easily keep the opening of the tank open.

In more detail, the packaging container 1, for example, is an article such as a cigarette box (“pack”) for packaging a cigarette T, which is a packaging object, wherein the packaging container 1 has an inner package inside the tank 5. Packaging material that can pack a cigarette T, used as material of packaging container 1.

An example of such a paper material is high-performance printed coating (registered trademark) paper material having a density of 221 g / m ³ manufactured by MeadWestvaco Corporation. The paper material is not limited to such paper material, and any suitable paper material can be used.

The inner packaging is designed to directly pack a group of cigarettes T until the packaging container 1 is opened, and can prevent the contamination of cigarettes T. The inner packaging has, for example, a moisture retention property and a flavor retention property. As the inner packaging, mainly paper is used, on which an aluminum layer is deposited in the form of a foil or deposited from the vapor phase.

As shown in FIG. 3 and 4, the packaging container 1 is made by assembling a preform 1 obtained from paper material by cutting.

As shown in FIG. 1-4, the reservoir 5 is formed by a part of the outer casing 9 and the inner casing 10. The specified reservoir 5 is formed by a part of the outer casing 9 and the inner casing 10 in the form of a square casing having an open end opening inside the specified reservoir 5.

In particular, the upper end of the reservoir 5 is obliquely open downward from the rear to the front side of the outer casing 9. In the reservoir 5, a wall extending from the upper end of the opening of the outer casing 9 is formed by an inner casing 10 provided on the inner peripheral surface of the inclined opening of the outer casing 9. Said reservoir 5 is box-shaped by an outer casing 9 and an inner casing 10, so that the top of the substantially square casing is open. The specified tank 5 contains a first front wall 11, a first rear wall 12, a pair of first side walls 13, a rear wall formed by parts of the outer casing 9 and the inner casing 10.

The first front wall 11 is made of a rectangular, for example, oblong shape, shorter in the width direction than in the height direction, when viewed from above. The first rear wall 12 is oblong in shape above the first front wall 11 in the height direction. The first rear wall 12 has at its upper end a cover 6 integrally formed through a hinge 7. Both sides of the upper edge (hinge 7) of the first rear wall 12 are obliquely cut down. In other words, both sides of the upper edge of the first rear wall 12 are made beveled upward to the central side, while the first rear wall 12 is provided with a hinge 7, continuous with the cover 6 at a given height.

Each of the first side walls 13 connects together the first front wall 11 and the first rear wall 12 and is made trapezoidal in shape with an inclined upper end. For example, the upper end of the first side wall 13 is inclined downward at two different angles of inclination to increase the angle of inclination from the first back wall 12 to the first front wall 11. The lower wall is oblong, seen from above, and connects the first front wall 11, the first rear wall 12 and a pair of first side walls 13 together on the lower end side.

The front inner wall 15 is provided on the inner surface of the first front wall 11 and protrudes from above the first front wall 11. The side inner walls 16 are respectively provided on the inner surfaces of the pair of the first side walls 13 and respectively protrude from above the first side walls 13. The rear inner wall 17 is provided on the inner the surface of the first rear wall 12, so that the rear inner wall 17 is located on at least part of the first rear wall 12, in particular on at least all of the inclined chastkov at both ends of the first rear wall 12 and the upper edge 7 of the hinge.

The front inner wall 15, the side inner walls 16 and the rear inner wall 17 of the inner body 10 are adhesively bonded to the inner surfaces of the first front wall 11, the first rear wall 12 and the first side walls 13 by, for example, an adhesive agent. The inner casing 10 forms a wall along the first front wall 11, the first rear wall 12 and the first side walls 13 of the outer casing 9 and is designed to guide the cover 6 and prevent crushing of the cover 6.

A portion of the inner housing 10 located in the first rear wall 12 forms a portion of the engaging portions 8. The inner housing 10 is configured to secure the lid 6 relative to the reservoir 5 by partially engaging the inner surface of the lid 6 when the lid 6 closes the end with the opening of the reservoir 5.

The lid 6 is formed by another part of the outer casing 9. The lid 6 comprises a second front wall 21, a second rear wall 22, a pair of second side walls 23 and an upper wall 24. The lid 6 is configured to close the opening of the tank 5 by covering the top of the tank 5.

The second front wall 21 is made of elongated shape, longer in the width direction than in the height direction, when viewed from above, and the width of which is essentially equal to the width of the first front wall 11.

The second rear wall 22 is oblong in shape above the first front wall 21 in the height direction. The tank 5 is integrally formed with the lower end of the second rear wall 22 through the hinge 7. Both sides of the lower edge (hinge 7) of the second rear wall 22 are obliquely cut down.

In other words, both sides of the lower edge of the second rear wall 22 are sloped downwardly on the outer side, and the second rear wall 22 is provided with a hinge 7 continuous with the first rear wall 12. In other words, the second rear wall 22 is inclined at both ends and, thus, has protrusions 26 protruding downward from the hinge 7 to the first rear wall 12.

Each of the second side walls 23 connects the second front wall 21 and the second rear wall 22 together. The specified second side wall 23 is made of a trapezoidal shape having an inclined lower end. The angle of inclination of the lower end of the second side wall 23 is essentially equal to the angle of inclination of the upper end of the first side wall 13. The upper wall 24 is oblong, seen from above, and connects the second front wall 21, the second rear wall 22 and a pair of second front walls 23 together side of the upper end.

A hinge 7 is provided between the first rear wall 12 and the second rear wall 22 and integrally connects the first rear wall and the second rear wall 22. The hinge 7 is configured to rotate the second rear wall 22 relative to the first rear wall 12. The hinge 7 is formed, for example, by a notch 7a, formed by indentation of the paper material or intermittent incision section 7b.

The engaging portions 8 comprise protrusions 26 provided on the second rear wall 22, and contact portions 27 in contact with the protrusions 26 when the cover 6 is rotated in the direction of travel from the reservoir 5. These protrusions 26 are provided in the second rear wall 22 of the cover 6 and protrude from the second the rear wall 22 on the side opposite the lid 6, through the hinge 7, that is, protrude to the first rear wall 12 of the tank 5.

The second side surfaces 37 form the second side walls 23 intersecting at right angles with the second front surface 36 (second front wall 21) when the notches 61 and 62 are bent.

The first adhesive surfaces 38 comprise a pair of side adhesive surfaces 44, a pair of lower adhesive surfaces 45, a pair of upper adhesive surfaces 46, and a front adhesive surface 47.

A pair of side adhesive surfaces 44 forms the first side adhesive surfaces 48, adhesive connected to the first side surfaces 35, and the second side adhesive surfaces 49, adhesive connected to the second side surfaces 37. A pair of side adhesive surfaces 44 forms the inner surfaces of the first side wall 13 and the second side walls 23. A pair of side adhesive surfaces 44 are square in shape, in which the first side wall 13 and the second side wall 23 are combined. A pair of side adhesive surfaces 44 is formed integrally with the rear surface 31, a pair of lower adhesive surfaces 45, a pair of upper adhesive surfaces 46 through nicks 52, 53, 64, 65, 66 and 67.

The pair of lateral adhesive surfaces 44 has cut-through portions 56a continuous with the cut-out portion 56 of the rear surface 31. One side, in other words, the lower part of the pair of lateral adhesive surfaces 44 from the cut-out portions 56a, forms the first side adhesive surfaces 48. The other side, in other words, the upper part of the pair of side adhesive surfaces 44 forms second side adhesive surfaces 49. The cutting sections 56a are inclined at substantially the same angle as the first side surfaces 35 and the second side surfaces 37. When the nicks 52 and 53 are bent, the first side adhesive surfaces 48 and the second side adhesive surfaces 49 intersect at right angles with the rear surface 31 (the first rear surface 41 and the second rear surface 42), and the pair of side adhesive surfaces 44 faces the first side surfaces 35 and second side surfaces 37, respectively.

A pair of lower adhesive surfaces 45 is formed integrally with a pair of first side adhesive surfaces 48 through nicks 64 and 65. When said nicks 64 and 65 are bent, a pair of lower adhesive surfaces 45 intersect at right angles with side adhesive surfaces 44 (first side wall 13 and second side wall 23), facing the bottom surface 32 and adhesively connected to the bottom surface 32.

When bent through the notch 63, the second front adhesive surface 47 faces the second front surface 36 and is adhesively connected to the second front surface 36. Said second front adhesive surface 47 forms part of the inner the surface of the second front wall 21.

The second preform 4 is a piece of material cut by punching paper material into a shape in which the inner housing 10 is expanded. Said second blank 4 comprises a front surface 74, a pair of side surfaces 75 and a pair of rear surfaces 76. A front surface 74, a pair of side surfaces 75 and a pair of rear surfaces 76 are formed integrally through a pair of notches 71 and 72.

The front surface 74 forms a front inner wall 15. The front surface 74 is formed to have substantially the same width as the first front wall 11 and is connected to a pair of side surfaces 75 through nicks 71, 71. The front surface 74 has nicks 74a. These nicks 74a are made by notching the front surface 74 from its side on a portion of the side surfaces 75 over the notches 71, 71, and engage with the inner surface of the lid 6. The front surface 74 is designed so that part of its upper part is cut off. The lower part of the front surface 74 is adhesively connected to the inner surface of the first front wall 11.

The lateral surfaces 75 form the inner side walls 16. These lateral surfaces 75 are designed to have substantially the same width as the first side walls 13, and are integrally formed with the front surface 74 and the rear surfaces 76 through the notches 71 and 72. The lower parts of the lateral surfaces 75 are adhesive connected to the inner surfaces of the first side walls 13.

The rear surfaces 76 form the rear inner wall 17. These rear surfaces 76 are made so wide that they can be located in positions facing the protrusions 26 provided in at least the second rear wall 22. These rear surfaces 76 are connected to the side surfaces 75 through the notches 72. The lower parts of the rear surfaces 76 are adhesively connected to the inner surface of the first rear wall 12.

The first preform 3 and the second preform 4, made as described above, have nicks that are bent in the same direction and adhesively connected to the corresponding surfaces by coating the first adhesive surfaces 38 with an adhesive agent. Thus, the first preform 3 forms an outer casing 9 having a reservoir 5 and a cover 6, and the second preform 4 forms an inner casing 10. Said inner casing 10 is then adhesively bonded to the corresponding position of the outer casing 9, so that the packaging container 1 is assembled. The way the outer casing 9 and the inner casing 10 of the packaging container 1 are adhesive connected to each other is not described in detail here.

A packaging container 1, made as described above, accommodates cigarettes T when a group of cigarettes packaged in an inner package is provided in the packaging container 1 during the execution of the packaging container 1 from the blank 2. The outer periphery of the packaging container 1 in which the cigarette group is packed, wrapped in a wrapping film such as a transparent film. The result is a cigarette product.

The following describes how to open the packaging container 1, made as described above, and how to open and close the lid 6. First of all, the packaging container 1, wrapped in a wrapping film, is printed by removing the wrapping film. After removing the wrapping film, the lid 6 is moved away from the reservoir 5. As a result of the movement of the lid 6, the hinge 7 bends and the lid 6 can rotate around the hinge 7.

When the cover 6 rotates around the hinge 7, the protrusions 26 provided in the second rear wall 22 of the cover 6 also rotate around the hinge 7. At the same time, the protrusions 26 protrude in the opposite direction to the second rear wall 22 through the hinge 7, so that the protrusions 26 move into the tank 5 if the lid 6 is rotated in the opening direction, as shown in FIG. 2. Thus, the protrusions 26 engage with the rear inner wall 17 of the inner housing 10. This engagement resists the movement of the cover 6 in the direction of rotation, and the tendency of the cover 6 to rotate can be prevented due to the elasticity of the hinge 7.

Thus, the packaging container 1 can keep the opening of the tank 5 open by the protrusion 26 and the inner case 10 without holding the lid 6 by hand, so that the cigarettes T stored in the tank 5 are easier to remove.

To keep the opening of the reservoir 5 closed by means of the lid 6 in the packaging container 1, the lid 6 is rotated around the hinge 7 in the direction of movement of the lid 6 to the reservoir 5. The engagement of the protrusions 26 of the rear inner wall 17 is released by rotation. As the rotation continues, the inner casing 10 comes into contact with the inner surface of the lid 6, and the lid 6 engages with the protrusions 74a of the inner casing 10, so that the lid 6 is fixed to the reservoir 5. As a result, the packaging container 1 closes.

In the packaging container 1, made as described above, if the lid 6 is rotated around the hinge 7, so that the lid 6 moves from the reservoir 5, the protrusions 26 protruding from the hinge 7 are rotated to the inner case 10 and come into contact with the inner case 10. As a result of this contact, the protrusions 26 and the inner housing 10 engage with each other. The engagement of the protrusions 26 and the inner case 10 serves as a means of resisting rotation about the hinge 7, and the lid 6 is fixed by this resistance in the open state of the tank 5. Thus, the lid 6 remains turned without being held in a turned position by hand, so that the tank 5 remains open, and T cigarettes can be easily removed from reservoir 5.

As described above, in the packaging container 1 according to the first embodiment of the invention, it is possible to easily keep the opening of the tank 5 open by turning the protrusions 26 provided in the lid 6 so that the protrusions 26 engage with the inner case 10.

In addition, the contact portion 27A is a recess 17a of the rear inner wall 17A.

Next, with reference to FIG. 7 and 8, a blank is described for making the packaging container 1, as well as making the packaging container 1A from the blank 2A. In FIG. 7 and 8, the dashed-dotted line indicates the folding lines of the workpiece 2A, and the solid lines indicate the cut sections.

The preform 2A comprises a first preform 3A and a second preform 4A.

The first preform 3A is a piece of material cut by punching paper material into a shape in which the outer casing 9A, including the reservoir 5A and the lid 6A, is expanded. The first preform 3A comprises a rear surface 31A, a lower surface 32, a first front surface 33, an upper surface 34, a pair of first side surfaces 35, a second front surface 36, a pair of second side surfaces 37 and first adhesive surfaces 38.

The rear surface 31A forms the first and second rear walls 12A and 22A and the hinge 7A. The specified rear surface 31A is made square in which the first and second rear walls 12A and 22A are combined. The specified rear surface 31A is formed integrally with the lower surface 32, the upper surface 34 and the first adhesive surfaces 38 through the notches 50, 51, 52 and 53. The rear surface 31A has a notch 54 and an arcuate slotted portion 55A provided in the center of the notch 54. The specified notch 54 and the slotted portion 55A form a hinge 7A and a protrusion 26A.

When the notches 50, 51, 52 and 53 are bent, the rear surface 31A forms a first rear wall 12A and a second rear wall 22A, intersecting at right angles with the lower surface 32 (lower wall) and the upper surface 34 (upper wall 24) of the first rear surface 41A and a second rear surface 42A.

The second preform 4A is a piece of material cut by punching paper material into a shape in which the inner housing 10A is expanded. The specified second workpiece 4A contains a front surface 74, a pair of side surfaces 75 and a pair of rear surfaces 76 formed integrally through the notches 71 and 72.

A pair of rear surfaces 76A forms a rear inner wall 17A. In particular, one of the pair of rear surfaces 76 forms part of the rear inner wall 17A, and the other forms the other part of the rear inner wall 17A. For example, as shown in FIG. 8, one of the pair of rear surfaces 76A is made longer in width than the other, and the notch 17a is made in one of the pair of rear surfaces 76A. The lower parts of the rear surfaces 76A are adhesive connected to the inner surface of the first rear wall 12.

The first preform 3A and the second preform 4A, made as described above, have notches that are bent in the same direction and are adhesive bonded to their respective surfaces by coating the first adhesive surfaces 38 with an adhesive agent. Thus, the first blank 3A forms an outer case 9A having a reservoir 5A and a cover 6A, and the second blank 4A forms an inner case 10A. Said inner case 10A is then adhesively bonded to the entire inner surface of the outer case 9A to assemble the packaging container 1A.

The following describes how the lid 6A of the packaging container 1A is held, made as described above. When the cover 6A is rotated around the hinge 7A, the protrusion 26A provided in the second rear wall 22A of the cover 6A also pivots around the hinge 7A. Said protrusion 26A is configured to protrude from the hinge 7A in a direction opposite to the second rear wall 22A, so that said protrusion 26A moves into the reservoir 5A if the lid 6A is rotated in the opening direction. Thus, said protrusion 26A abuts and engages with a notch 17a on the rear inner wall 17A of the inner housing 10A. This engagement resists the movement of the cover 6A in the direction of movement and can control the rotation of the rotated cover 6A resulting from the elasticity of the hinge 7A, even if elasticity occurs.

Thus, the packaging container 1A can keep the opening of the tank 5A open without manually holding the lid 6, so that cigarettes T located in the tank 5A can be easily removed. Accordingly, the packaging container 1A may provide preferred effects similar to those of the packaging container 1 described above.

As described above, in the packaging container 1A of the second embodiment of the present application, it is possible to easily keep the tank 5A open by turning the protrusion 26A provided in the lid 6A so that the protrusion 26A engages with the inner housing 10A.

The present invention is not limited to the first and second embodiments disclosed above. For example, instead of performing an external shape in the form of a rectangular parallelepiped, the packaging container 1 and the packaging container 1A can be made with inclined vertices or with vertices in the form of curved surfaces.
