Description

[Technical Field]

[0001] The present invention relates to a fitting container comprising a container body and a lid, and more particularly to an inner fitting container in which the lid is fitted into the container body. [Background technology]

[0002] Conventionally, fitting containers for storing food such as sashimi have employed outer fitting containers in which a lid fits onto the outside of a container body. This is because it has generally been thought that with outer fitting containers, the fitting portion is located on the outside of the container edge, which effectively prevents the contents, such as sashimi or garnish, from getting caught in the fitting portion. However, in reality, even with outer fitting containers, the contents, such as sashimi or garnish, have frequently become caught.

[0003] Furthermore, due to their structure, outer fitting containers generally have inferior airtightness compared to the inner fitting containers shown in Patent Documents 1 to 3, and therefore have problems such as the contents leaking easily, the contents drying out easily, and the lids coming off easily.However, when inner fitting containers such as those shown in Patent Documents 1 to 3 are used as fitting containers for storing food such as sashimi, a problem arises in that the contents, such as sashimi and garnishes, are prone to getting caught in the container. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 4929320 [Patent Document 2] JP 2003-63573 [Patent Document 3] Patent Publication No. 2016-55884 Summary of the Invention [Problem to be solved by the invention]

[0005] In view of the above problem, the present invention provides an inner fitting container in which contents are less likely to become caught in the fitting portion. [Means for solving the problem]

[0006] In order to solve the above problem, the internal fitting container according to claim 1 of the present invention comprises a lid body having a lid-side fitting portion and a container body having a container-side fitting portion, the lid-side fitting portion being internally fitted into the container-side fitting portion, the container body having a pinching prevention wall inside the container-side fitting portion that protrudes above the bottom wall of the container-side fitting portion, the height from the bottom wall to the upper end of the pinching prevention wall is at least half the height of the container-side fitting portion, the inner inclined surface of the pinching prevention wall is not covered by the side wall of the lid body but is exposed to the inside, In order to double prevent the contents from getting inside, the upper end of the jamming prevention wall does not abut on the lid body, and there is a small gap above the upper end of the jamming prevention wall; The lower end of the side wall of the lid and the upper end of the jam prevention wall Alternately The anti-trapping wall is arranged laterally offset, and the inner inclined surface of the anti-trapping wall faces the lower end of the side wall of the lid body.

[0007] According to the above feature, since the height from the bottom wall of the container-side fitting portion to the upper end of the jamming prevention wall is equal to or greater than half the height of the container-side fitting portion, even if the contents are about to get caught in the container-side fitting portion, the jamming prevention wall effectively prevents the contents from entering the container-side fitting portion. As a result, when the lid is closed, it is possible to effectively prevent the contents from getting caught between the container-side fitting portion and the lid-side fitting portion.

[0008] Furthermore, the inner fitting container according to claim 2 of the present invention is characterized in that the width of the jamming prevention wall is equal to or greater than half the width of the container-side fitting portion.

[0009] According to the above feature, the jamming prevention wall, which is positioned inside the container side fitting portion, keeps the contents away from the container side fitting portion, effectively preventing the contents from getting into the container side fitting portion.

[0010] Furthermore, the internal fitting container according to claim 3 of the present invention is characterized in that the jamming prevention walls are provided only on the sides of the container body.

[0011] According to the above features, the largest area of ​​contact with the contents contained within the container body is the edge of the container body, so by providing a jam prevention wall along that edge, jamming of the contents is effectively prevented. [Effects of the Invention]

[0012] In the inner fitting container of the present invention, the contents are less likely to get caught in the fitting portion. [Brief explanation of the drawings]

[0014] 100 Lid 140 Lid side fitting part 200 container body 230 Anti-bite wall 231 Upper end 240 Container side fitting part 242 Bottom Wall H1, H2 height 300 Inner fitting container DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In this specification, "upward" refers to a direction that faces upward in the vertical direction when the container body of the inner fitting container is placed on a horizontal surface with the open side facing upward, and "downward" refers to a direction that faces downward in the vertical direction.

[0016] 1 and 2 show a lid 100 for an inner fitting container 300 according to the present invention. Fig. 1(a) is a plan view of the lid 100, Fig. 1(b) is a side view of the lid 100, Fig. 2(a) is an AA end view of Fig. 1(a), and Fig. 2(b) is an enlarged end view of the part surrounded by the dotted line.

[0017] As shown in Figures 1 and 2, the lid 100 has a shallow dish shape that opens downward and includes a top plate 110 that is rectangular in plan view and a side wall 120 that extends downward from the top plate 110. A covering portion 130 that extends diagonally downward is provided at the lower end 121 of the side wall 120, and a convex lid-side fitting portion 140 is provided at the lower end of the covering portion 130. Furthermore, a flat flange portion 150 that extends horizontally from the upper end of the lid-side fitting portion 140 is provided outward of the lid-side fitting portion 140. The side wall 120, covering portion 130, lid-side fitting portion 140, and flange portion 150 are provided continuously around the entire circumferential direction of the lid 100.

[0018] 2, the lower end 121 of the side wall 120 protrudes from the inner surface 131 of the covering portion 130, creating a step between the lower end 121 and the covering portion 130. Furthermore, the lid-side fitting portion 140 includes an inner wall 141 hanging down from the covering portion 130, a flat bottom wall 142 extending substantially horizontally from the inner wall 141, and an outer wall 144 rising from the bottom wall 142. Furthermore, the outer wall 144 includes an inclined surface 143 that slopes diagonally downward from the inside to the outside. This inclined surface 143 is a so-called undercut portion.

[0019] Next, the container body 200 of the internal fitting container 300 according to the present invention is shown in Figures 3 and 4. Figure 3(a) is a plan view of the container body 200, Figure 3(b) is a side view of the container body 200, Figure 4(a) is a B-to-B end view of Figure 3(a), Figure 4(b) is an enlarged end view of the part surrounded by the dotted line in Figure 4(a), and Figure 4(c) is an enlarged plan view of the vicinity of a corner portion 262 of the container body 200.

[0020] 3 and 4, the container body 200 has a shallow dish shape that opens upward, and includes a bottom wall 210 that is rectangular in plan view, legs 211 that bulge downward from the bottom wall 210, and side walls 220 that are formed to rise from the legs 211. Furthermore, a jamming prevention wall 230 is provided at the upper end of the side wall 220, and a concave container-side fitting portion 240 is provided on the outer side of the jamming prevention wall 230. Furthermore, a flat flange portion 250 is provided outside the container-side fitting portion 240, extending horizontally from the upper end side of the container-side fitting portion 240. The side walls 220, the container-side fitting portion 240, and the flange portion 250 are provided continuously around the entire circumferential direction of the container body 200.

[0021] 3(a) and 4(c), the jamming prevention wall 230 is formed only along the side portion 261 of the container body 200, but is not formed around the corner portion 262 of the container body 200. Around the corner portion 262, an inclined surface 221 is formed that slopes from the end of the jamming prevention wall 230 toward the center of the corner portion 262. Therefore, around the corner portion 262, the jamming prevention wall 230 appears to be cut away by the inclined surface 221.

[0022] Furthermore, the lower end of the inclined surface 221 is continuous with a rib 222 extending vertically. As shown in FIG. 3(b), this rib 222 is formed in a convex shape extending outward from the side wall 220 at the corner portion 262. Furthermore, the rib 222 extends from the lower end 223 to the upper end 224. The width of the rib 222 gradually increases, forming a generally triangular shape in side view. The lower ends 223 of the ribs 222 are flush with the lower ends of the legs 211, so that when the container body 200 is placed on a flat surface, the lower ends 223 can directly abut against the flat surface. The upper ends 224 of the ribs 222 are continuous with the container-side fitting portion 240.

[0023] When fitting the lid 100 to the container body 200, downward pressing force is applied to the corner portion 262. However, the corner portion 262 is reinforced by the ribs 222 extending in the vertical direction, increasing its buckling strength, so the corner portion 262 does not deform and the lid 100 can be easily fitted to the container body 200. Furthermore, the stress applied to the corner portion 262 is transmitted from the upper end 224 to the lower end 223 of the rib 222 and dispersed to the flat surface on which the container body 200 is placed. Moreover, because the width of the upper end 224 side of the rib 222 is wider than the lower end 223, the stress applied to the container-side fitting portion 240 continuous with the upper end 224 can be effectively absorbed by the upper end 224 side and dispersed to the lower end 223.

[0024] 4(b), the container-side fitting portion 240 includes an inner wall 241 that hangs down from the jamming prevention wall 230, a flat bottom wall 242 that extends substantially horizontally from the inner wall 241, and an outer wall 244 that rises from the bottom wall 242. The outer wall 244 includes an inclined surface 243 that slopes obliquely downward from the inside to the outside. The inclined surface 243 is a so-called undercut portion, and is the portion that strongly abuts against the inclined surface 143 of the lid 100.

[0025] The jamming prevention wall 230 has an inner inclined surface 232 that slopes from the upper end 231 toward the side wall 220, and an outer inclined surface 233 that slopes from the upper end 231 toward the container-side fitting portion 240. The jamming prevention wall 230 is provided inside the container-side fitting portion 240, and protrudes upward beyond the bottom wall 242 of the container-side fitting portion 240. The height H1 of the jamming prevention wall 230, i.e., the height H1 from the bottom wall 242 of the container-side fitting portion 240 to the upper end 231, is more than half the height H2 of the container-side fitting portion 240. The height H2 of this container side fitting portion 240 means the height from the bottom wall 242 of the container side fitting portion 240 to the upper end of the container side fitting portion 240, and in the embodiment shown in Figure 4, it is the height from the bottom wall 242 of the container side fitting portion 240 to the upper end 245 of the inclined surface 243 of the outer wall 244.

[0026] Furthermore, width L1 of jam prevention wall 230 is at least half of width L2 of container-side fitting portion 240. Note that width L1 of jam prevention wall 230 refers to the length from inner end 234 of jam prevention wall 230 to outer end 235 of jam prevention wall 230 in the vertical cross section of container body 200, as shown in Figure 4(b), and width L2 of container-side fitting portion 240 refers to the length from inner end 246 of container-side fitting portion 240 to outer end 247 of container-side fitting portion 240.

[0027] The lid 100 and container body 200 according to this embodiment are made of a sheet-like material having a thickness of about 0.1 to 1.0 mm that can be hot-formed, and for example, A-PET, transparent biaxially oriented polystyrene (center OPS), or polypropylene (PP) can be used as the material for the lid 100 to ensure visibility of the contents and to have appropriate elasticity, while A-PET, filler-containing polypropylene (PPF), or polystyrene (PS) can be used as the material for the container body 200. Furthermore, although the lid 100 and container body 200 are rectangular in plan view, they can be appropriately changed to any other shape, such as a polygonal shape or a substantially circular shape in plan view.

[0028] Next, referring to Fig. 5, the internally fitted container 300 is shown in a state where the lid body 100 is internally fitted into the container body 200. Fig. 5 is an end view of the internally fitted container 300 in a state where the lid body 100 shown in Fig. 2(a) is fitted into the container body 200 shown in Fig. 4(a), and is an enlarged view of the periphery of the fitted portion.

[0029] 5, when the lid 100 is placed over the opening of the container body 200 and the lid-side fitting portion 140 of the lid 100 is fitted into the container-side fitting portion 240 of the container body 200, the internal fitting container 300 is sealed. The internal fitting container 300 contains an item X, such as sashimi or garnish, but is not limited thereto, and various types of food can be contained inside the internal fitting container 300.

[0030] Furthermore, due to its structure, the internal fitting container 300 has a high level of airtightness, with the lid side fitting portion 140 and the container side fitting portion 240 not easily coming apart, so problems such as leakage of the contents X, the contents X drying out easily, and the lid body 100 easily coming off are less likely to occur.

[0031] Furthermore, in the inner fitting container 300 of the present invention, the height H1 from the bottom wall 242 of the container-side fitting portion 240 to the upper end 231 of the pinch prevention wall 230 is equal to or greater than half the height H2 of the container-side fitting portion 240, so even if the contained item X is about to enter the container-side fitting portion 240, the pinch prevention wall 230 effectively prevents the contained item X from entering the container-side fitting portion 240. As a result, when the lid 100 is closed, it is possible to effectively prevent the contained item X from entering the container-side fitting portion 240 and becoming pinched between the container-side fitting portion 240 and the lid-side fitting portion 140.

[0032] Note that the configurations, such as the shapes, of the lid-side fitting portion 140 and the container-side fitting portion 240 vary depending on the type of inner fitting container 300 and the usage environment, and the degree of fit between the lid-side fitting portion 140 and the container-side fitting portion 240 also varies. However, to prevent the lid body 100 from accidentally coming off the container body 200, it is ideal for the lid-side fitting portion 140 to fit over at least half of the height of the container-side fitting portion 240. Under such ideal circumstances, there is a possibility that the contained item X will become caught over more than half of the height of the container-side fitting portion 240. Therefore, under such circumstances, it has been determined that, in order to effectively prevent the contained item X from becoming caught, it is optimal for "the height H1 from the bottom wall 242 of the container-side fitting portion 240 to the upper end 231 of the entrapment prevention wall 230 to be more than half of the height H2 of the container-side fitting portion 240."

[0033] 5, as long as the height H1 of the jamming prevention wall 230 is at least half of the height H2 of the container-side fitting portion 240, the height H1 of the jamming prevention wall 230 may be greater than the height H2 of the container-side fitting portion 240, and the upper end 231 of the jamming prevention wall 230 may protrude above the container-side fitting portion 240. By making the height H1 of the jamming prevention wall 230 greater than the height H2 of the container-side fitting portion 240, the contained item X can be more effectively prevented from getting into the container-side fitting portion 240.

[0034] Furthermore, in the internal fitting container 300 of the present invention, the width L1 of the jamming prevention wall 230 is more than half the width L2 of the container side fitting portion 240, so the jamming prevention wall 230, which is positioned more inward than the container side fitting portion 240, separates the contained item X from the container side fitting portion 240, effectively preventing the contained item X from entering the container side fitting portion 240.

[0035] Note that as long as the width L1 of the jamming prevention wall 230 is at least half of the width L2 of the container-side fitting portion 240, the width L1 of the jamming prevention wall 230 may be 70% or more of the width L2 of the container-side fitting portion 240. Furthermore, as shown in Fig. 5, the width L1 of the jamming prevention wall 230 may be wider than the width L2 of the container-side fitting portion 240. By making the width L1 of the jamming prevention wall 230 wider than the width L2 of the container-side fitting portion 240, the contained item X is further away from the container-side fitting portion 240, and therefore, the contained item X can be more effectively prevented from getting into the container-side fitting portion 240.

[0036] Furthermore, the jamming prevention wall 230 is a portion that prevents the contained item X from reaching the container-side fitting portion 240, and therefore has an inner inclined surface 232 and an outer inclined surface 233, giving it an uneven shape. If the jamming prevention wall 230 has a complex uneven shape, the contained item X will hit the uneven parts, This makes it more difficult for the contained item X to reach the container-side fitting portion 240, and as a result, it is possible to more effectively prevent the contained item X from getting into the container-side fitting portion 240. Note that the shape of the jamming prevention wall 230 is not limited to that shown in Fig. 4, and for example, the upper end 231 may be a flat surface or may have an uneven surface.

[0037] Furthermore, the cover portion 130 of the lid body 100 is configured to cover the jam prevention wall 230 with a small gap between it and the jam prevention wall 230. Therefore, even if the contained item X protrudes above the jam prevention wall 230, the contained item X will not be crushed by the cover portion 130.

[0038] Furthermore, the lower end 121 of the side wall 120 protrudes from the inner surface 131 of the cover portion 130 toward the jamming prevention wall 230. Therefore, even if the contained item X tries to get in between the cover portion 130 and the jamming prevention wall 230, the lower end 121 can effectively prevent the contained item X from getting in.

[0039] Furthermore, the extending directions of the lower end 121 of the side wall 120 and the upper end 231 of the jam prevention wall 230 are staggered. In other words, the lower end 121 and the upper end 231 are not aligned vertically in a straight line, but are offset horizontally. Therefore, even if the contained item X tries to get between the cover 130 and the jam prevention wall 230, the lower end 121 and the upper end 231 doubly prevent the contained item X from getting in between.

[0040] Furthermore, as shown in FIG. 5, the upward extension direction of the inner inclined surface 232 of the jamming prevention wall 230 intersects with the cover portion 130, so that the contained item X that protrudes beyond the inner inclined surface 232 is bent along the extension direction of the inner inclined surface 232, but the tip of the contained item X abuts against the cover portion 130 and is pushed back, so that the contained item X can be more effectively prevented from entering the container side fitting portion 240.

[0041] Furthermore, the container-side fitting portion 240 of the container body 200 is disposed above the bottom wall 210 of the container body 200. Therefore, the contents X accommodated on the bottom wall 210 are less likely to enter the container-side fitting portion 240.

[0042] Furthermore, in the inner fitting container 300 of the present invention, as shown in FIGS. 3(a) and 4(c), the entrapment prevention walls 230 are provided only on the side portions 261 of the container body 200. Because the side portions 261 of the container body 200 have the largest area in contact with the contents X contained in the container body 200, the entrapment prevention walls 230 are provided along the side portions 261 to effectively prevent the contents X from getting entrapped. In addition, the entrapment prevention walls 230 are provided only on the side portions 261 of the container body 200, and not on the corner portions 262. Since the attachment and detachment of the lid 100 is performed starting from the corner portions 262, not providing the entrapment prevention walls 230 on the corner portions 262 prevents the entrapment prevention walls 230 from interfering with a part of the lid 100 and interfering with the attachment and detachment of the lid 100.

[0043] Although the internal fitting container 300 of the present invention is an internal fitting type, it is not limited to this, and the internal fitting container of the present invention may also be an internal and external fitting type that has the characteristics of both internal fitting and external fitting by providing a fitting portion on the anti-biting wall 230 side.

[0044] Furthermore, the internally fitted 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.
