paper container

Abstract

A paper container includes a base plate unit, a side panel unit, an extension unit, and a cover unit. The side panel unit includes a first side panel and a second side panel. The first side panel has a top edge and an insert groove. The extension unit has two spaced-apart outer edge segments. The cover unit includes two spaced-apart front edge portions and an insertion portion between the front edge portions. Each front edge portion has two front cover edges positioned opposite the outer edge segments. When the cover unit is placed on the side panel unit, the insertion portion is inserted into the insert groove, the front edge portions abut against the top side of the extension unit, and the front cover edges are aligned with the outer edge segments. Due to the structural design of the insertion portion being able to insert into the insert groove, this invention eliminates the need for additional elastic bands, making it more environmentally friendly.

Claims

1. A paper container comprising: a base plate unit; a side panel unit extending upward from the periphery of the base plate unit and surrounding the base plate unit to define a holding space, the side panel unit including a first side panel and a second side panel spaced apart from the first side panel, the first side panel having a top edge and an insert groove adjacent to the top edge and communicating with the holding space. An extension unit, connected to the enclosure unit and extending in a direction away from the holding space, having an outer edge spaced from the top edge, the outer edge having two spaced outer edge segments; and a cover unit, including a body portion, two spaced front edge portions extending in a direction away from the body portion, and a plug portion located between the front edge portions and positioned corresponding to the embedding groove, the body portion having a connecting end connected to the second enclosure of the enclosure unit, the front edge portions each having two front cover edges opposite to the connecting end and positioned corresponding to the outer edge segments, when the cover unit is placed on the enclosure unit, the body portion covers the holding space, the plug portion is inserted into the embedding groove, the top side of the plug portion abuts against the bottom side of the extension unit and does not protrude from the extension unit, the front edge portions abut against the top side of the extension unit and do not protrude from the extension unit, and the front cover edges are respectively aligned with the outer edge segments.

2. The paper container as described in claim 1, wherein, The vertical distance between the outermost two sides of the embedding groove in a vertical direction is one groove width, and the groove width is no more than 0.5cm.

3. The paper container as claimed in claim 1, wherein, The extension unit includes a first extension plate extending from the top edge. The first extension plate has an extension portion and a flange portion extending from the extension portion toward the holding space. The extension portion has an outer edge, and the flange portion has an inner edge opposite to the outer edge and spaced apart from the top edge. When the cover plate unit is placed on the enclosure plate unit, the flange portion abuts against the top side of the body portion.

4. The paper container as claimed in claim 1, wherein, The first enclosure and the second enclosure are connected to the two opposite sides of the base plate unit. The enclosure unit also includes two side enclosures that are spaced apart and connected to the other two opposite sides of the base plate unit, and several end plates connected to the inner sides of the side enclosures.

5. The paper container as claimed in claim 1, wherein, The first enclosure and the second enclosure are connected to the two opposite sides of the base plate unit. The enclosure unit also includes two side enclosures that are spaced apart and connected to the other two opposite sides of the base plate unit. Each side enclosure has a folded edge opposite to the base plate unit. The extension unit also includes two side extension plates that extend outward from the folded edges respectively.

6. The paper container as claimed in claim 1, wherein, The distance between each leading edge and the connecting end is greater than the distance between the plug-in portion and the connecting end.
