Description

[Technical field]

[0001] The present invention relates to a packaging container. [Background technology]

[0002] 2. Description of the Related Art Conventionally, packaging containers for storing food have been used in supermarkets, convenience stores, and the like.

[0003] There are various types of packaging containers, and the packaging containers of Patent Document 1 and Patent Document 2 include a container body and a lid body that fits into the container body. When packaging containers are displayed, they are stacked vertically and stacked high, making it difficult to check the contents in the packaging container and the labels attached to the top surface. Therefore, the packaging containers of Patent Document 1 and Patent Document 2 are designed to be stacked diagonally, making it easy to check the contents in the packaging container and the labels attached to the top surface. However, stacking the packaging containers diagonally makes the positions and postures of the stacked packaging containers unstable, and there is a risk that the packaging containers will shift or fall.

[0012] Hereinafter, each embodiment of the present invention will be described with reference to the drawings. In this specification, "upward" refers to a direction toward the top in the vertical direction when the packaging container is placed on a horizontal surface, and "downward" refers to a direction toward the bottom in the vertical direction.

[0013] <Embodiment 1> 1 shows a container body 100 of a packaging container 300 according to a first embodiment of the present invention. Fig. 1(a) is a plan view of the container body 100, and Fig. 1(b) is a side view of the container body 100.

[0014] As shown in FIG. 1, the container body 100 is made of a synthetic resin sheet, has a deep dish shape that opens upward, and has a generally rectangular shape in plan view with corner portions 101 at the four corners. The container body 100 has a flat bottom surface 110 that spreads horizontally, a side surface 120 that continues upward from the bottom surface 110, a container-side fitting portion 130 that is recessed outward at the upper end of the side surface 120, and a flat outer edge 140 that extends outward from the upper end of the container-side fitting portion 130. The side surface 120, the container-side fitting portion 130, and the outer edge 140 are provided continuously or intermittently over the entire circumference of the container body 100 in the circumferential direction. The container body 100 has a generally rectangular shape in plan view, but is not limited to this, and can have any shape, such as a generally polygonal shape or a generally circular shape in plan view. The side surface 120 is inclined obliquely upward with respect to the bottom surface 110, but is not limited to this, and may be perpendicular to the bottom surface 110.

[0015] In addition, legs 150 bulging downward are provided on outer edges 111 of each side of bottom surface 110. Furthermore, side surface 120 located at corner portion 101 is provided with ribs 160 protruding outward from the surface of side surface 120.

[0016] The container body 100 is formed by sheet molding (e.g., vacuum forming, pressure forming, hot plate forming, vacuum pressure forming, etc.) using a plastic (synthetic resin) sheet having a thickness of approximately 0.1 mm to 1.0 mm (millimeters). For example, the material for the container body 100 may be polystyrene, polypropylene, polyethylene, A-PET, polylactic acid, or biaxially oriented versions of these.

[0017] 2 shows a lid 200 of a packaging container 300 according to the first embodiment of the present invention. FIG. 2(a) is a plan view of the lid 200, and FIG. 2(b) is a side view of the lid 200.

[0018] As shown in Fig. 2, the lid 200 is made of a synthetic resin sheet, has a deep dish shape that opens downward, and has a generally rectangular shape in plan view with corner portions 201 at the four corners. The lid 200 has a flat top surface 210 that spreads horizontally, a side surface 220 that continues downward from the top surface 210, a lid-side fitting portion 230 that protrudes outward at the lower end of the side surface 220, and a flat outer edge 240 that extends outward from the lid-side fitting portion 230. The side surface 220, the lid-side fitting portion 230, and the outer edge 240 are provided continuously or intermittently over the entire circumference of the lid 200 in the circumferential direction. Although the lid 200 has a generally rectangular shape in plan view, the shape is not limited thereto, and may have any shape, such as a generally polygonal shape in plan view or a generally circular shape in plan view.

[0019] Further, at the corner portion 201, a rib 260 is provided which protrudes upward from the side surface 220. An upper end 261 of the rib 260 is a flat surface which is flush with the top surface 210. A groove-shaped latched portion 270 is provided between the top surface 210 and the rib 260.

[0020] The lid body 200 is formed by sheet molding (e.g., vacuum forming, pressure forming, hot plate forming, vacuum pressure forming, etc.) using a plastic (synthetic resin) sheet having a thickness of approximately 0.1 mm to 1.0 mm (millimeters). For example, the material for the lid body 200 may be polystyrene, polypropylene, polyethylene, A-PET, polylactic acid, or biaxially oriented versions of these.

[0021] Next, a state in which the packaging containers 300 of the present invention are stacked diagonally will be described with reference to Fig. 3 to Fig. 5. Fig. 3 is an overall perspective view of the packaging containers 300 in a diagonally stacked state, Fig. 4(a) is an enlarged front view of the packaging containers 300 in a diagonally stacked state, enlarged view of the vicinity of the hooking portion, Fig. 4(b) is an enlarged rear view of the packaging containers 300 in a diagonally stacked state, and Fig. 5 is an enlarged side view of the packaging containers 300 in a diagonally stacked state, enlarged view of the vicinity of the hooking portion.

[0022] First, as shown in Figures 3 to 5, the lid body 200 is attached so as to cover the container body 100 from above, and the packaging container 300 is sealed with food or the like contained therein. At this time, the lid body side fitting portion 230 of the lid body 200 is internally fitted into the container side fitting portion 130 of the container body 100. In addition, since the outer edge 240 of the lid body 200 and the outer edge 140 of the container body 100 overlap vertically, the intrusion of dust or the like into the packaging container 300 is effectively prevented.

[0023] The lower packaging container 300 is placed on a horizontal surface. As shown in FIG. 5, the upper packaging containers 300 are stacked diagonally so that the side surface 120 of the container body 100 of the upper packaging container 300 is placed on the top surface 210 of the lid body 200 of the lower packaging container 300. In addition, the outer edge 140 of the container body 100 of the upper packaging container 300 and the outer edge 240 of the lid body 200 are hooked to the hooked portion 270 of the lower packaging container 300, so that the position and posture of the upper packaging container 300 stacked diagonally are unlikely to shift, and it is possible to stack them diagonally stably. For example, as shown in FIG. 6, when multiple packaging containers 300 are stacked vertically high, the packaging container 300 stacked at the top is stacked diagonally as shown in FIG. 3 to FIG. 5. This allows the consumer to easily check the contents in the packaging container 300 and the label attached to the lid body 200, etc.

[0024] As shown in FIG. 5, the outer edge 140 of the container body 100 and the outer edge 240 of the lid body 200 of the upper packaging container 300 become the hooking portion that hooks onto the hooked portion 270, but are not limited thereto. For example, only the outer edge 140 of the container body 100 or only the outer edge 240 of the lid body 200 may be the hooking portion that hooks onto the hooked portion 270. In addition, the hooking portion is configured so that it can be hooked onto the hooked portion 270 of the lower packaging container 300 in either the horizontal or vertical direction. In addition, the hooked portion 270 is configured in a groove shape, but is not limited thereto, and may be any configuration as long as the hooking portion can be hooked.

[0025] 4(b) and 5, the rib 160 of the container body 100 of the packaging container 300 protrudes outward from the side surface 120. The rib 160 of the container body 100 of the upper packaging container 300 is located outside the top surface 210 of the lid body 200 of the lower packaging container 300 and protrudes downward from the top surface 210. Therefore, even if the upper packaging container 300 is about to shift sideways, the rib 160 of the container body 100 of the upper packaging container 300 abuts against the outside of the top surface 210 of the lid body 200 of the lower packaging container 300 and stops, so that the position and posture of the upper packaging container 300 stacked diagonally are unlikely to shift, and the diagonally stacked packaging containers 300 can be stably stacked.

[0026] 6 is a side view of the packaging containers 300 stacked horizontally. The lower packaging container 300 is placed on a horizontal surface, and the bottom surface 110 of the container body 100 of the upper packaging container 300 is placed on the top surface 210 of the lid body 200 of the lower packaging container 300. As a result, the upper packaging container 300 is placed in a horizontal position relative to the lower packaging container 300. In addition, the legs 150 of the container body 100 of the upper packaging container 300 surround the outer periphery of the top surface 210 of the lid body 200 of the lower packaging container 300, so that the position and posture of the upper packaging container 300 in the stacked tier are unlikely to shift, and the stacking can be stably performed horizontally.

[0027] <Embodiment 2> Next, Fig. 7(a) shows a packaging container 300A according to a second embodiment of the present invention. Fig. 7(a) is an enlarged side view of the vicinity of the hooking portion in the packaging container 300A in a state where the packaging containers 300A are stacked diagonally. The packaging container 300A according to the second embodiment differs from the packaging container 300 according to the first embodiment only in that the container body 100A has a flange portion 170A. The other configurations of the packaging container 300A according to the second embodiment are basically the same as those of the packaging container 300 according to the first embodiment, so detailed description will be omitted.

[0028] As shown in FIG. 7(a), the outer edge 140A of the container body 100A of the packaging container 300A has a flat flange portion 170A that extends further outward from the outer edge 140A. The flange portion 170A extends further outward than the outer edge 240A of the lid body 200A. Since the flange portion 170A of the upper packaging container 300A is hooked to the hooked portion 270A of the lower packaging container 300A, the position and posture of the upper packaging container 300A stacked diagonally are unlikely to shift, and the diagonally stacked containers can be stably stacked. As shown in FIG. 7(a), the flange portion 170A of the upper packaging container 300A becomes the hooking portion that hooks to the hooked portion 270A, but is not limited thereto. For example, the flange portion 170A may not be provided on the outer edge 140A of the container body 100A, but may be provided on the outer edge 240A of the lid 200A to serve as a hook portion that hooks onto the hooked portion 270A.

[0029] <Embodiment 3> Next, Fig. 7(b) shows a packaging container 300B according to embodiment 3 of the present invention. Fig. 7(b) is an enlarged side view of the vicinity of the hooking portion in the packaging container 300B in a state where the packaging containers 300B are stacked diagonally. The packaging container 300B according to embodiment 3 differs from the packaging container 300 according to embodiment 1 only in that the container-side fitting portion 130B serves as the hooking portion. The other configurations of the packaging container 300B according to embodiment 3 are basically the same as those of the packaging container 300 according to embodiment 1, and therefore detailed description thereof will be omitted.

[0030] As shown in FIG. 7(b), the container side fitting portion 130B of the upper packaging container 300B can be inserted into and hooked to the hooked portion 270B of the lower packaging container 300B, so that the position and posture of the upper packaging container 300B stacked diagonally are unlikely to shift, and the packaging containers 300B can be stacked diagonally stably. Note that the container side fitting portion 130B of the upper packaging container 300B is a hooking portion that hooks to the hooked portion 270B of the lower packaging container 300B, but is not limited thereto. For example, as shown in FIG. 5, the outer edge 140 of the container body 100 and the outer edge 240 of the lid body 200 may be the hooking portion, or as shown in FIG. 7(a), the flange portion 170A may be the hooking portion. As long as the hooking portion can be hooked to the hooked portion 270 in this way, the hooking portion may be any portion near the outer edge of the packaging container 300.

[0031] <Embodiment 4> Next, Fig. 8 to Fig. 12 show a packaging container 300C according to embodiment 4 of the present invention. Fig. 8(a) is a plan view of the lid body 200C according to embodiment 4 of the present invention, Fig. 8(b) is a side view of the lid body 200C, Fig. 9 is an overall perspective view of the packaging container 300C in a state where it is stacked diagonally, Fig. 10(a) is an enlarged front view of the vicinity of the hooking part in the packaging container 300C in a state where it is stacked diagonally, Fig. 10(b) is an enlarged rear view of the vicinity of the hooking part in the packaging container 300C in a state where it is stacked diagonally, and Figs. 11(a) and (b) are enlarged side views of the vicinity of the hooking part in the packaging container 300C in a state where it is stacked diagonally. In addition, the packaging container 300C of embodiment 4 differs from the packaging container 300 of embodiment 1 only in the configuration of the lid body 200C, and other configurations are basically the same as those of the packaging container 300 of embodiment 1, so detailed explanations will be omitted.

[0032] As shown in FIG. 8, the lid 200C is made of a synthetic resin sheet, has a shallow dish shape that opens downward, and has a generally rectangular shape in plan view with corners 201C at the four corners. The lid 200C has a flat top surface 210C that spreads horizontally, a side surface 220C that continues downward from the top surface 210C, a lid-side fitting portion 230C that protrudes outward at the lower end of the side surface 220C, and a flat outer edge 240C that extends outward from the lid-side fitting portion 230C. The side surface 220C, the lid-side fitting portion 230C, and the outer edge 240C are provided continuously or intermittently over the entire circumference of the lid 200C in the circumferential direction. The lid 200C has a generally rectangular shape in plan view, but is not limited thereto, and may have any shape, such as a generally polygonal shape in plan view or a generally circular shape in plan view.

[0033] Additionally, a rib 260C is provided on the outer periphery of the top surface 210C so as to protrude upward from the top surface 210C. The rib 260C is provided with a groove-shaped latched portion 270C that is recessed downward.

[0034] 9 to 11 show the state in which the packaging containers 300C of the present invention are stacked diagonally. First, the lid 200C is attached so as to cover the container body 100C from above, and the packaging container 300C is sealed with food or the like contained therein. At this time, the lid side fitting portion 230C of the lid 200C is fitted inside the container side fitting portion 130C of the container body 100C. In addition, the outer edge 240C of the lid 200C and the outer edge 140C of the container body 100C are overlapped vertically, effectively preventing the intrusion of dust or the like into the packaging container 300C.

[0035] The lower packaging container 300C is placed on a horizontal surface. As shown in Fig. 10(b) and Fig. 11, the upper packaging container 300C is stacked diagonally so that the rib 160C, which is a part of the side surface 120C of the container body 100C of the upper packaging container 300C, is placed on the top surface 210C of the lid body 200C of the lower packaging container 300C. Since the outer edge 140C of the container body 100C of the upper packaging container 300C and the outer edge 240C of the lid body 200C are hooked to the hooked portion 270C of the lower packaging container 300C, the position and posture of the upper packaging container 300C stacked diagonally are unlikely to shift, and the diagonally stacked packaging container 300C can be stably stacked. For example, when multiple packaging containers 300 are stacked vertically high as shown in Fig. 12, the topmost packaging container 300 is stacked diagonally as shown in Figs. 9 to 11. This allows consumers to easily check the contents of the packaging container 300C and the labels attached to the lid body 200C.

[0036] As shown in FIG. 11, the outer edge 140C of the container body 100C of the upper packaging container 300C and the outer edge 240C of the lid body 200C are the hooking parts that hook onto the hooked parts 270C. The hooking parts are configured so that they can be hooked onto the hooked parts 270C of the lower packaging container 300C either horizontally or vertically. The hooked parts 270C are configured in a groove shape, but are not limited to this, and may have any configuration as long as the hooking parts can be hooked. The outer edge 140C of the container body 100C of the packaging container 300C and the outer edge 240C of the lid body 200C are the hooking parts that hook onto the hooked parts 270C, but are not limited to this, and may be any location near the outer edge of the packaging container 300C as long as they can be hooked onto the hooked parts 270C.

[0037] 10(b) and 11, the rib 160C of the container body 100C of the upper packaging container 300C is located inside the rib 260C of the top surface 210C of the lid body 200C of the lower packaging container 300C. Therefore, even if the upper packaging container 300C is about to shift sideways, the rib 160C of the container body 100C of the upper packaging container 300C abuts against the rib 260C of the top surface 210C of the lid body 200C of the lower packaging container 300C and stops, so that the position and posture of the upper packaging container 300C stacked diagonally are unlikely to shift, and the diagonally stacked packaging containers 300C can be stably stacked.

[0038] 12 is a side view of the packaging containers 300C stacked horizontally. The lower packaging container 300C is placed on a horizontal surface, and the bottom surface 110C of the container body 100C of the upper packaging container 300C is placed on the top surface 210C of the lid body 200C of the lower packaging container 300C. As a result, the upper packaging container 300C is placed in a horizontal position relative to the lower packaging container 300C. In addition, the leg portion 150C of the container body 100C of the upper packaging container 300C is located inside the rib 260C of the lid body 200C of the lower packaging container 300C, so that the position and posture of the upper packaging container 300 are unlikely to shift, and the stacking can be stably performed horizontally.

[0039] The packaging container 300 of the present invention in the embodiment is an internal fitting type, but is not limited to this and may be an external fitting type or an internal and external fitting type having features of both internal and external fitting.

[0040] The packaging container of the present invention is not limited to the above examples, and various modifications and combinations are possible within the scope of the claims and the scope of the embodiments, and these modifications and combinations are also included in the scope of rights.
