Benefits of technology

"The present invention provides a bag that can change its size to accommodate goods of various sizes. The bag has a first side fabric, a second side fabric, and two lateral fabrics connected to each other to form a room with an opening at the top. The first side fabric is longer than the second side fabric, so when the opening is open, the bag will be bigger, and when the opening is close, the bag will be smaller. The second side fabric has an extended portion to form a bottom of the bag and a front shade portion to form a front side of the bag. The bag can also have a zip to open and close the opening, and a cord and fastener to secure the opening and keep goods in more securely."

Problems solved by technology

In other words, a conventional bag is unable to store goods of a size greater than its fixed space.
Moreover, even when the bag doesn't store any goods therein, it will still take room and cause a waste of space.
However, such pocket has limited capacity of storing goods and may not safely keep the goods therein.
A drawback of such pocket is that its size cannot be expanded.

Embodiment Construction

[0021]FIG. 1 shows an expanded view of a bag 1 of the preferred embodiment of the present invention and FIG. 2 is the perspective view thereof. The bag 1 is made of flexible and soft fabrics including a first side fabric 10, a second side fabric 20, a first lateral fabric 30 and a second lateral fabric 40. These fabrics are stitched together to form the bag 1 with a room 1a therein. As shown in FIG. 1, the first side fabric 10 is a rectangular fabric having a top side 12, a bottom side 14, and first and second long sides 16, 18. The second side fabric 20 is a rectangular fabric also having a top side 22, a bottom side 24, and first and second long sides 26, 28. The bottom side 24 of the second side fabric 20 and the bottom side 14 of the first side fabric 10 are stitched together. The first lateral fabric 30 has two lateral sides 32, 34 stitched to the first long side 16 of the first side fabric 10 and the second long side 28 of the second side fabric 20 respectively. The second lat...

Abstract

A bag of the present invention includes a first side fabric, a second side fabric, and two lateral fabrics connected to each other to form the bag with a room therein and an opening at a top thereof. The first side fabric has a first length, which is longer than a second length of the second side fabric. The bag provides various means for closing and opening the opening of the bag and when the opening is open, the second side fabric will fall outward until the lateral fabrics are bound tight to get a bigger space for storing goods.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to a bag for storage, and more particularly to a bag of a changeable size thereof.[0003]2. Description of the Related Art[0004]Typically, a bag, such as handbag or backpack, has a room therein to store goods. A conventional bag usually has a fixed room to store goods with size equal to or smaller than the space. In other words, a conventional bag is unable to store goods of a size greater than its fixed space. Moreover, even when the bag doesn't store any goods therein, it will still take room and cause a waste of space.[0005]Some backpacks have pockets on lateral sides to receive goods that user may need frequently, such as water bottle. Such pocket is made by stitching flexible fabric on the backpack. The fabric is attached on the backpack when there is nothing received therein. However, such pocket has limited capacity of storing goods and may not safely keep the goods therein....
