1. A container with pre-guided alignment function comprising:
a container body, with a cup-type body or cartridge body which forms an outer peripheral wall, a bottom wall, an open end, the accommodating space and the open end extending outwardly flaring edge of the enlarged diameter; a cover; which is located at the open end of the container with open and close state, and when the cover on the container is closed, so the peripheral cover overlying the expanding edge; a group embedded edge part is set on the open end of the container and the relative position of cover; the interaction between groups embedded edge parts makes the cover fit to open end of the container; plural locking parts with pre-guided function are disposed between the outer peripheral edge of on the container and the relative position of peripheral edge of the cover, showing as male and female coupling relationship; the locking parts comprise: two locking parts edge with spaced patterns, with the engaging part alignment engaged, it makes the cover tightly that can overly the flaring edge of the container; at least need one long alignment, when the locking parts of the locker on the bit edge is engaged; the edge of locking parts will use long guided alignment part as alignment point; it could effectively prevent the angle inaccuracy or even become deformed between the edges of locking parts caused by the uneven force; which does not align the locking parts accurately or engage the locking parts with their counterparts; it could avoid structural damage during the engagement, significantly improved convenience; efficiency such practical progress. |
