Besides, the edge of the open hole is coated, for example, with a thermoplastic resin to prevent the infiltration of filtered water.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water purifier, and more particularly to a foldable water purifier that is not bulky to carry and has a compact appearance at the time of sale.

[0002]

2. Description of the Related Art As a water purifier, a faucet mounting type having a filter device inside is generally popular.
In addition, it is known that an opening hole is provided at the bottom of a paper cup and an activated carbon sheet is attached to the inner surface of the bottom so as to cover the opening hole.

[0003]

However, in the case of a faucet-mounting type water purifier, it is expensive, and in any case, whether it is directly mounted on the faucet of the water supply or installed near the faucet. There is a problem that it cannot be used outdoors because it takes up space.

Further, in the case of the conventional simple type water purifier in which the activated carbon sheet is adhered to the bottom plate of the paper cup, since it cannot be folded, there is a problem that it is bulky to carry and bulky to package. Also, it is necessary to hold it by hand so that it does not fall when it is placed on a cup or the like.

Therefore, it is an object to provide a foldable water purifier which can be manufactured at low cost and can be used anywhere regardless of its size, and is not bulky when carried and can be folded and compactly packaged at the time of sale. . An object of the present invention is to solve such a problem.

[0006]

[Means for Solving the Problems] The above-mentioned problems are as follows: A foldable tray-like box body having a bottom plate having an opening hole and having a filtering function so as to cover the opening hole is formed. The problem can be solved by arranging the filter member having.

The foldable water purifier having the above structure can be manufactured at a much lower cost than the faucet mounting type, and
It does not matter where it is used, it is not bulky because it can be folded when it is carried, and it can be folded at the time of sale to make it a compact appearance, and it can be folded and made into a bundle to pack a plurality into a compact package.

In the foldable water purifier, the blank plate is formed by connecting a blank plate having a substantially square shape and a bottom plate portion having an opening hole in the center, four side plate portions connected to the bottom plate portion, and adjacent side plate portions. The connecting flaps at the four corners of the water purifier are preferably used. In that case, a locking flap that is bent outward to be used as a mounting and fixing means of the water purifier is continuously provided at the tip edges of the pair of side plates facing each other. As a result, it is not necessary to hold it by hand when using it on a cup or the like.

In the foldable water purifier, the blank plate has a substantially rectangular bottom plate portion having an opening hole in the center, four side plate portions connected to the bottom plate portion, and adjacent side plate portions connected to each other. The connecting pieces between the adjacent side plate portions of the blank plate are attached to the outer surface of the side plate portion in a folded state, and the bottom plate portion and a pair of opposing side plate portions are used for predetermined folding. It is often possible to provide a ruled line so that it can be assembled into a box with one touch, which improves convenience in use.

Further, the blank plate is preferably made by coating the edge of the bottom opening hole with a thermoplastic resin, and by doing so, the rigidity of the box body due to the permeation of the filtered water from the end surface of the bottom opening hole is improved. It can prevent the deterioration.

Further, the portion of the filter member corresponding to the peripheral edge of the bottom opening hole of the blank plate may be subjected to sealing processing by a hot press, and even in such a case, filtered water permeates from the end face of the bottom opening hole. Can be prevented, and a decrease in box rigidity can be prevented. In addition, the filter member,
A portion of the blank plate corresponding to the bottom opening hole may be formed so as to fit into the opening hole. Even in such a case, permeation of filtered water from the end surface of the bottom opening hole is prevented, and the rigidity of the box body is reduced. Can be prevented.
