Description

The packing box of good seal performance

Technical field

The utility model relates to a kind of packing box, the packing box of especially a kind of bottom band draw-in groove.

Background technology

Packing box is widely used in the packing of various article.Present various packing box comprise box body with at the bottom of the box that box body is connected, constitute by the preceding tongue, the back tongue that cooperates with preceding tongue, left tongue and the right tongue that link to each other with bottom, box body four sides at the bottom of the box, left tongue and right tongue doubling, again before tongue with after the tongue doubling laminate, reach the bottom surface and encapsulate.Box opening place sidewall is connected with two box tongues that inside invagination increases leak tightness, and side box tongue is parallel opposite-compacting type structure, bottle is sealed after covering lid.The shortcoming of said structure is: because left tongue and right tongue closure when pressing is poor, flexible left tongue and right tongue easily are drawn out, and are held up at the bottom of in use can having box, and interior items is replaced easily, the inner easy stolen phenomenon of awards that is provided with.

The utility model content

The purpose of this utility model solve exactly existing packing box because of box at the bottom of leak tightness not strong, the phenomenon that causes interior items easily to be replaced or to steal.

The technical solution adopted in the utility model is: the packing box of good seal performance, it comprise box body with at the bottom of the box that box body is connected, constitute by the preceding tongue, the back tongue that cooperates with preceding tongue, left tongue and the right tongue that link to each other with bottom, box body four sides at the bottom of the box, described left tongue and right tongue front end are respectively equipped with the opposite open slot of opening direction, make left tongue and right tongue overlap mutually by open slot.

Adopt technique scheme, because left tongue and right tongue overlap mutually by open slot, so left tongue and right tongue just can not be pulled out from the slit, thereby reach the problem that increases leak tightness.

In sum, the beneficial effects of the utility model are: because the left tongue and the right tongue of the utility model packing box bottom can overlap mutually by open slot, therefore increased the leak tightness of packing box.
