Description

Comfortable portable slippers

Technical Field

The utility model relates to the technical field of daily necessities, concretely relates to are comfortable portable slippers.

Background

Slippers can be broadly divided into two types: a flip-flop is commonly called a flip-flop and a straight-line flip-flop. The comfortable and beautiful slippers can not only improve the image, but also add a beautiful landscape to the life of people.

With the pace of life increasing, a trip or a trip is more and more common, but for people who often go on a trip or a trip wearing shoes, it is necessary to have a pair of slippers which are convenient to carry and use. For this reason, patent No. CN2016205973539 discloses a portable antiskid slipper and shoe spike, comprising a shoe spike, which is arranged in front of the shoe; the shoe buckle is arranged at the back of the shoe, and the shoe nail is inserted into the shoe buckle to form a herringbone slippers structure. The carrying is convenient, and the convenience is brought to the carrying. However, the slippers need to be taken off by wearing the socks, and the slippers are very inconvenient for people who wear the shoes to travel or people in northern cold areas (namely, people who wear the shoes to travel and wear the socks are very inconvenient and tedious for people who wear the shoes to travel and wear the socks to and fro, and the feet can be frozen when the people wear the socks or do not wear the socks in northern cold areas). In addition, other structures are not arranged on the shoe buckle, so that the shoe buckle cannot be well attached to the instep of a human body when being turned over, and the slipper is easy to slip off from the foot when being worn, so that the slipper is very uncomfortable to wear. Therefore, the pair of straight slippers is more convenient and more suitable for people who often go on a business trip or travel and wear shoes. However, the existing single-line mop is very inconvenient to carry, and the main reasons are as follows: firstly, the weight is heavy, inconvenient carrying and hard. Secondly, the molding is fixed, can not change, and difficult the accomodating occupies that the volume is great. So people rarely go out with slippers.

In order to ensure personal hygiene and convenient use, the slippers provided in each hotel or each hotel are disposable plastic slippers, and the slippers are not water-resistant and are not wearable, so the slippers have no preservation value. After being used, the medicine is directly discarded, so the dosage is very large. Not only causes resource waste, but also the discarded disposable plastic slippers are not easy to degrade in natural environment, and the pollution to the environment (including air, soil and the like) can exist for a long time, thereby further influencing the health of people.

Accordingly, the inventors of the present invention have made extensive studies and improvements on conventional slippers, and have made the present invention.
