Stand-up paper bag
A stand-up paper bag is provided with a bottom panel; two major panels joined one ends wherein one major panel includes a first fold line formed with the bottom panel; and two minor panels each joined the major panels, each minor panel including a crease. The bottom panel includes a first sub-panel adjacent to the first fold line, an extension distal the first fold line, a second sub-panel between the first sub-panel and the extension, a second fold line between the first sub-panel and the second sub-panel, a third fold line between the extension and the second sub-panel, a first triangular incision on one ends of the first and second sub-panels, and a second triangular incision on other ends of the first and second sub-panels.
1. Field of the Invention
The invention relates to paper bags and more particularly to a paper bag capable of standing erect.
2. Description of Related Art
A conventional paper bag A is shown in
It is often that a plurality of paper bags A are stacked together for shipping. Each of the minor panels A2 may be collapsed inwardly to form a crease A21 due to weight of items in the paper bags A. However, the bottom panel A4 may be projected outwardly to form a fold line A43 along its central portion (see
Thus, the need for improvement still exists.
SUMMARY OF THE INVENTIONIt is therefore one object of the invention to provide a stand-up paper bag comprising a bottom panel; two major panels joined one ends wherein one major panel includes a first fold line formed with the bottom panel; and two minor panels each disposed between and joined the major panels, each of the minor panels including a lengthwise crease; wherein the bottom panel includes a first sub-panel adjacent to the first fold line, an extension distal the first fold line, a second sub-panel formed between the first sub-panel and the extension, a second fold line formed between the first sub-panel and the second sub-panel, a third fold line formed between the extension and the second sub-panel, a first triangular incision formed on one ends of the first and second sub-panels, and a second triangular incision formed on other ends of the first and second sub-panels.
The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.
Referring to
After placing item(s) in the bag 1, a person may first fold the bottom panel 13 along the fold line 111. Next, the person may fold the extension 132 toward the top major panel 11 along the fold line 1321 until the extension 132 is engaged with an inner surface of the top major panel 11 and hidden (see
It is often that a plurality of paper bags 1 are stacked together for shipping (see
Referring to
A plurality of elongated holes 1A are formed in each fold line 1311, 1321, or 111 (or crease 121). The holes 1A facilitate the folding operation of the panels.
While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
Claims
