Abstract

(57) [Summary] [Purpose] To provide a plastic container with a rib for preventing adhesion, which is effective in preventing adhesion between containers that frequently occur everyday. [Structure] A plurality of convex ribs 3 are provided so as to project on the outer peripheral surface of the container body 2, and the ribs 3 are formed in a vertically long shape in which the inclination increases from the rim of the container body 2 toward the bottom, and ribs are formed when they are stacked. 3 creates a gap to prevent the container from sticking.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a plastic container with ribs for preventing adhesion, which is particularly suitable for stacking storage after cleaning.

[0002]

[Prior art]

 Generally, ceramics and glass containers used as tableware are stored by type and size, and plastic containers are not exceptions and are stored in multiple layers.

[0003]

[Problems to be solved by the device]

 By the way, if containers of the same type and shape are stacked and stored, the stacking surfaces may come into close contact with each other, making removal extremely difficult. Since the surface of a plastic container is smooth, especially when it is stored without sufficient draining after washing, the water adhered to the stacking surface increases the adhesion, making removal extremely difficult. Further, it is considered that if air is enclosed between the containers by the close contact, the close contact between the containers is further enhanced by the pressure difference between the inside and the outside. In such a case, forcibly peeling off has a disadvantage that the container is cracked or deformed. An object of the present invention is to provide a plastic container with a rib for preventing close contact, which is effective in preventing close contact between such containers that frequently occur every day.

[0004]

[Means for Solving the Problems]

 The plastic container with ribs for preventing adhesion according to the present invention is provided with a plurality of convex ribs protruding from the outer peripheral surface of the container body, and the ribs are formed in a vertically long shape in which the inclination increases from the rim of the container body toward the bottom. is there.

[0005]

[Action]

 Due to the overlapping of the containers, a gap corresponding to the height of the rib is created between the containers, and the containers do not adhere to each other. Further, since the ribs are vertically long in the height direction of the container and the upper surface of the rib is inclined, the stacking with the mating container is stable.

【Example】

 Hereinafter, an embodiment of a plastic container with a rib for preventing adhesion according to the present invention will be described with reference to FIGS. 1 and 2. The figure shows a container 1 injection-molded in a dish shape, for example, from polypropylene. Usually, a plurality of ribs 3 are radially provided at equal intervals on the outer circumference of the container body 2 which is usually circular in plane. The rib 3 projects in a convex shape from the outer peripheral surface of the container body 2 and extends vertically from the rim toward the bottom, and the upper surface 4 thereof is formed as a slope having a gradually increasing slope from the rim 5 side to the bottom 6 side. . At least three ribs 3 are preferably installed. If the number of the ribs 3 is one or two, it is easily understood that the ribs 3 are not stable with respect to the container 1 to be overlapped. In this sense, the number of ribs 3 installed is three or more.

As shown in FIG. 2, the shape of the rib 3 is a mountain shape having a gentle curved slope as a whole in consideration of the contact condition between the lower container 1A and the upper container 1B which overlap each other, and has a sharp corner. Shapes with edges can be avoided. Since the upper container 1B is superposed on the lower container 1A by sliding down, the upper container 1B is superposed by forming the upper surface 4 of the rib 3 into a slope that gradually increases from upper to lower. Is done smoothly and smoothly. Further, by forming the upper surface 4 of the rib 3 into an inclined surface, the stability at the time of stacking is increased.

Therefore, as shown in FIG. 2, when the two containers 1A and 1B are overlapped with each other, a gap 5 corresponding to the height dimension of the rib 3 of the upper container 1B is formed between the lower container 1A and the lower container 1A. That is, the two containers 1A and 1B are in contact with each other in the area corresponding to the number of the ribs 3, and the inner and outer peripheral surfaces of both ribs theoretically hardly contact each other. In this way, the close contact between the two containers 1A and 1B is avoided. Actually, as shown in the figure, the containers are often stored face-down rather than the stack of containers 1A and 1B facing upward, and even if the drainage after cleaning is insufficient, the water droplets remaining on the container surface It is also possible to let it flow out from the gap 5. Also, by avoiding close contact, there is no air containment between the containers 1A and 1B, and due to the difference in atmospheric pressure inside and outside the container due to air containment as in the past, the closeness of contact is further enhanced, making removal more difficult. The inconvenience will be eliminated.

[0009]

[Effect of device]

 As described above, the plastic container with ribs for preventing adherence according to the present invention is suitable not only for stacking containers during normal operation but also for storing them by stacking them with each other by a rib when they are stacked and stored. When a gap is formed, draining and air removal can be performed, contact between containers can be prevented, and the container can be easily removed.
