Description

[Detailed explanation of the idea] The present invention relates to a plastic lid.

In conventional plastic lids of this type with hinges located on the outdoor side, the hinges may become plasticized, discolored, or brittle due to the effects of rain or high-energy ultraviolet rays from sunlight. There is a problem of deterioration based on factors such as change and weather resistance.

Therefore, in order to eliminate the above-mentioned problems, the present invention utilizes the flexibility (deformation and restoration) of plastic and also provides an eaves above the hinge part for the purpose of blocking sunlight, rain, etc. The purpose of this invention is to provide a plastic lid that can have the same hinge performance outdoors as when used indoors.

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

1 is a plastic lid, which is made of plastic material and has an integral bottom, and is hollowed out from the next part.

That is, an opening 10, a hinge 3 provided above the opening 10, an opening/closing part 4 that rotates around the hinge 3 to cover the opening 10, and a A stopper portion 7 provided at A stopper arm portion 6 is provided, and an eaves portion 2 extends outward from above the opening portion 10 and covers the hinge portion 3.

This plastic lid 1 is attached to a storage box 8 on the top of an ornamental seedling nursery 9, as shown in FIG. 4, for example.

The plastic lid 1 configured as described above has a handle portion 5.
When you pull the stopper arm part 6, the stopper part 7
Due to the flexibility of the hinge part 3, the opening/closing part 4 is
Open up to 0°.

By the way, the length of the eaves 2 that blocks rain and sunlight, etc.
The length of the eave 2 is 1 of the length from the root to the fold of the hinge part 3.
．． If it is at least 7 times as long, it will be able to block sunlight even at winter solar radiation angles and prevent rain from coming into contact with it.

As described above, according to the present invention, the original hinge function is not impaired at all even with the eaves attached, and compared to conventional plastic integral hinges without eaves, the hinges are less affected by UV rays, rain, etc. even when used outdoors. However, the performance of the hinge part is improved to the same extent as when used indoors.
