Description

Technical Field

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

Background Art

[0002] Conventionally, packaging containers for storing foods such as prepared foods have been used in supermarkets, convenience stores, etc.

[0003] Conventional packaging containers have a bottom surface, and convex ribs or the like on which foods can be placed are formed on the bottom surface. Then, by placing foods such as fried foods and prepared foods on this convex rib, oil, moisture, etc. that come out of the foods are made to flow from the convex rib to the bottom surface side so that the foods are not wetted with moisture or the like. However, in the case of foods with a large amount of moisture or the like, there has been a problem that the drained moisture accumulates on the bottom surface and adheres to the foods. Further, in Patent Document 1, there are convex ribs with an inclined top. However, since the bottom surface is horizontal, there is a problem that moisture or the like flowing out of the foods accumulates on the bottom surface, and when the foods move to a lower part along the inclination of the convex rib, the foods come into contact with the moisture or the like.

Summary of the Invention

Problems to be Solved by the Invention

[0005] Therefore, in view of the above problems, the present invention provides a packaging container in which it is difficult for moisture or the like to adhere to foods.

Means for Solving the Problems

[0006] In order to solve the above problems, the packaging container according to claim 1 of the present invention is a packaging container having a bottom surface including an inclined surface on which food can be placed, wherein convex ribs for placing the food are provided on the inclined surface, and the top of the convex ribs is inclined in a direction opposite to the inclination direction of the inclined surface.

[0007] According to the above characteristics, since the inclination direction of the top of the convex rib is opposite to the inclination direction of the inclined surface, the lowest part of the convex rib is located at the highest part of the inclined surface. Thus, when the packaging container is being transported or the like, even if the contents move along the inclination of the convex rib to the lower part, it is difficult for the contents to come into contact with the outflow, and it is possible to prevent the texture of the contents from being impaired.

[0008] Furthermore, the packaging container according to claim 2 of the present invention is characterized in that the top of the convex rib is inclined so as to be lower toward the front side of the packaging container, and the inclined surface is inclined so as to be lower toward the back side of the packaging container.

[0009] According to the above characteristics, the contents placed on the convex rib are accommodated so as to rise toward the front side of the packaging container so that they are easily visible to the consumer, and it looks good. Also, since the outflow flowing out from the stored items flows to the back side of the packaging container, it is less visible to the consumer and looks even better.

[0010] Furthermore, the packaging container according to claim 3 of the present invention is characterized in that a storage portion for storing the outflow flowing out from the food is provided on the lower side of the inclined surface.

[0011] According to the above characteristics, since the outflow can be stored in the storage portion, even if the packaging container is tilted during transportation of the packaging container or the like, it is possible to prevent the outflow from flowing back on the inclined surface and coming into contact with the contents, or the contents from being soaked in the outflow for a long time and impairing the texture of the contents.

Effect of the Invention

[0012] The packaging container of the present invention is such that moisture and the like do not easily adhere to the food.

Embodiments for Carrying Out the Invention

[0014] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In this specification, "upward" means the direction upward in the vertical direction when the packaging container is placed on a horizontal plane with the opening surface facing upward, and "downward" means the direction downward in the vertical direction.

[0015] First, FIGS. 1 to 3 show the packaging container 100 of the present invention. Note that FIG. 1 is a plan view of the packaging container 100, FIG. 2(a) is a front view of the packaging container 100, FIG. 2(b) is a side view of the packaging container 100, and FIG. 3 is a sectional view taken along line A - A shown in FIG. 1.

[0016] As shown in FIG. 1, the packaging container 100 has a shallow dish shape that opens upward, and includes a flat bottom surface 110 that is substantially rectangular in plan view, side walls 120 formed so as to rise from the outer periphery 111 of the bottom surface 110, and a flange portion 130 at the upper end of the side walls 120. Further, a skirt portion 140 that hangs downward is provided outside the flange portion 130, and an outwardly convex fitting portion 150 for fitting a lid body is optionally provided on the skirt portion 140. And the side walls 120, the flange portion 130, and the skirt portion 140 are continuously provided over the entire circumference in the circumferential direction of the packaging container 100.

[0017] Further, the bottom surface 110 is provided with an inclined surface 160 on which food can be placed. This inclined surface 160 is inclined so that the height decreases from one end 161 to the other end 162. Further, a plurality of convex ribs 170 protruding upward from the inclined surface 160 are provided on the inclined surface 160. The convex ribs 170 extend linearly in plan view, and the top 171 of the convex rib 170 is inclined so that the height decreases from the other end 173 to the one end 172. Note that the convex ribs 170 extend linearly in plan view, but are not limited thereto, and may have any shape such as a curved shape in plan view.

[0018] Then, as shown in FIG. 3, when the contents X such as fried foods and prepared vegetables are placed on the inclined surface 160 and the convex ribs 170, the outflow Y such as oil and moisture flowing out from the contents X flows along the inclination of the inclined surface 160 to the other end 162 side at a lower position. Therefore, it is difficult for the outflow Y to contact the contents X. In particular, since the inclination direction of the top 171 of the convex rib 170 is opposite to the inclination direction of the inclined surface 160, the one end 172 side, which is the lowest part of the convex rib 170, is located on the one end 161 side, which is the highest part of the inclined surface 160. Thus, even when the contents X move to the one end 172 side along the inclination of the convex rib 170 during transportation of the packaging container 100 or the like, it is difficult for the contents X to contact the outflow Y. Further, the other end 173 side, which is the highest part of the convex rib 170, is located on the other end 162 side, which is the lowest part of the inclined surface 160. Therefore, the protruding height at which the other end 173 side of the convex rib 170 protrudes upward from the other end 162 side of the inclined surface 160 is maximized. Thus, it is difficult for the contents X to contact the outflow Y.

[0019] Further, a storage portion 180 recessed downward is provided on the lower side of the inclined surface 160. Then, the outflow Y flows from the inclined surface 160 to the storage portion 180, and the outflow Y can be stored in the storage portion 180. Therefore, even when the packaging container 100 is tilted during transportation of the packaging container 100 or the like, it is possible to prevent the outflow Y from flowing back on the inclined surface 160 and contacting the contents X.

[0020] Also, as shown in FIGS. 1 and 3, the front 101 side of the packaging container 100 is the side that is easily visible to consumers when the packaging container 100 is on display. And the top 171 of the convex rib 170 is inclined so as to be lower toward the front 101 side of the packaging container 100. Therefore, the contents X placed on the convex rib 170 are accommodated so as to stand up toward the front 101 side of the packaging container 100 so that consumers can easily see them, and they look good. On the other hand, the inclined surface 160 is inclined toward the back side 102 opposite to the front 101 of the packaging container 100. And the back side 102 is the side that is less visible to consumers when the packaging container 100 is on display compared to the front 101 side. Therefore, by flowing the outflow Y flowing out from the contents X along the inclination of the inclined surface 160 to the back side 102 side, it is made difficult for consumers to see the outflow Y, and the appearance is further improved.

[0021] Note that the convex rib 170 is inclined so that its height decreases toward the front 101 side of the packaging container 100, and the inclined surface 160 is inclined so that its height decreases toward the back side 102 side of the packaging container 100. However, it is not limited to this. The convex rib 170 may be inclined so that its height decreases toward the back side 102 side, and the inclined surface 160 may be inclined so that its height decreases toward the front 101 side. As long as the inclination directions of the convex rib 170 and the inclined surface 160 are opposite, the inclination directions of the inclined surface 160 and the convex rib 170 may be in any direction.

[0022] Also, the bottom surface 110 of the packaging container 100 is provided with the inclined surface 160. However, it is not limited to this. As long as the packaging container 100 is provided with the inclined surface 160 in part, such as being provided with the inclined surface 160 and a horizontal surface, or being provided with a plurality of inclined surfaces 160, the packaging container 100 may be provided with facial portions of any shape in addition to the inclined surface 160. Also, when the packaging container 100 is provided with a plurality of inclined surfaces 160, each inclined surface 160 may be inclined in any direction, such as being inclined in the reverse direction at different positions.

[0023] In addition, the packaging container 100 is provided with a bulging portion 103 on the central side. The packaging container 100 is configured such that the central side is the highest and it becomes lower toward the outer end. However, it is not limited to this, and the packaging container 100 may have an arbitrary shape, such as a configuration where the central side is the lowest and it becomes higher toward the outer end.

[0024] Note that the packaging container 100 is formed by sheet forming (for example, vacuum forming, pressure air forming, hot plate forming) using a sheet-like material with a thickness of about 0.1 mm to 1.0 mm (millimeters). For example, as the material of the packaging container 100, polystyrene, polypropylene, A-PET, polylactic acid, or those obtained by biaxially stretching these, paper, metal, etc. can be used. Also, the packaging container 100 is substantially rectangular in plan view, but it is not limited to this and may have an arbitrary shape.

[0025] Note that the packaging container of the present invention is not limited to the above embodiments, and various modifications and combinations are possible within the scope described in the claims and the scope of the embodiments, and these modifications and combinations are also included in the scope of the right.
