The advantages of a portable toilet according to the present invention will be described as follows.
First, a portable toilet according to the present invention is configured to have a foldable structure so as to improve functionality and is configured to weigh less than a conventional one and have a small volume so as to be easily carried.
According to a conventional portable toilet, a seat stand is configured to be 36 or more cm wide so as to cover exposed bottoms. Additionally, the conventional portable toilet is configured to have a shape like a rectangular bag when packed. This leads to an increase in the weight and volume of the portable toilet. As a result, it is hard to carry the portable toilet during long distance travel. The present invention has the advantage of solving the problem with conventional portable toilets by reducing weight and volume.
A portable toilet according to the present invention, manufactured from plastics, weighs 800 or less g which is less than 900 g of a paper toilet that is available in the market and is repeatedly used.
Second, a portable toilet of the present invention is easily manipulated.
Most portable toilets with a minimum volume, except for toilets for infants, need to be assembled for use. According to the present invention, side body parts as legs of a body and a seat stand are foldably joined. Accordingly, if the portable toilet is manipulated once or twice, the portable toilet is easily installed and collapses.
Third, a solid and liquid waste envelope constituting a portable toilet of the present invention is easily attached and detached.
Envelope rods are used to attach and detach a solid and liquid waste envelope. Accordingly, the solid and liquid waste envelope can be expanded as much as possible and easily fixed. Additionally, the mouth of the solid and liquid waste envelope can be rapidly closed and the solid and liquid waste envelope can be easily detached.
Fourth, a portable toilet of the present invention has excellent stability compared to weight and volume.
Minimized weight and volume can lead to a reduction in stability when a user sits on a portable toilet. However, according to the present invention, side body parts consisting of legs of a body and a seat stand are foldably joined, thereby making it possible to stably install the portable toilet, give a user a pleasant feel when the user sits on the portable toilet, and ensure safety.
