example

[0029] with two handles (such as Figure 7 As shown, the bags of numbers 6 and 6') were molded with different handle designs listed in Table 1. Comparative Sample 1 was also molded to have the dimensions listed in Table 1. Figure 8 The bag of Comparative Sample 1 is shown. Using the computer simulation software Abaqus / provided by Dassault Systèmes The strength of the bag was tested and the following parameters were used to describe the bag and the test.

[0030] The bag has a rectangular shape with L5 being 395mm and L4 being 275mm. The bag is made of plastic film having a thickness of 92 μm, 0.9539 kg / m 3 Density, 1.568×10 9 Elastic modulus of Pa, and Poisson's ratio of 0.4. The joined front and rear panels in the portion between the tip 3 and the first seal line 5 had a thickness of 165.6 μm. The bottom end of the bag model is fixed in three-dimensional coordinates. The critical point of bag failure was defined as the equivalent plastic strain (PEEQ) at the tip of...

Abstract

The present invention discloses a bag having first and second opposing sides, a top end, a bottom end and a first seal line adjacent to said top end, said first and second opposing sides, top end and bottom end defining front and back panels of the bag, the bag including a handle positioned between the top end and the first seal line, the handle including a bottom portion, a top portion, and two arcuate portions connecting the bottom portion and the top portion ends, the two arcuate ends being mirror images of each other about the centers of the top portion and the bottom portion, wherein the arcuate ends extend from 0 to 180 degrees above the bottom portion toward the top portion, wherein each of the arcuate ends each comprising at least two arcs R1 and R3, wherein the junctions between the bottom portion, R1, R3 and top portion are respectively tangent, and wherein R1 has a radius r1, R3 has a radius r3, and r3 The ratio between and r1 is 1.1 to 3.4.

Description

technical field [0001] The present invention relates to a bag having a tear resistant handle with improved tear resistance durability. Background technique [0002] Conventional bags may generally include a handle for receiving a user's hand. This is usually the case if the filled bag exceeds a certain weight. Due to the heavy weight of the contents, such handles are prone to tearing by the force required to lift these bags. Furthermore, the repeated carrying and lifting process during handling, transport and storage can result in the pouch being torn open, which can cause the contents to spill. Such spills create waste that burdens manufacturers, distributors, retailers, and consumers, and also results in costs for cleaning. [0003] It is therefore an object of the present invention to provide a bag comprising a tear resistant handle. [0004] An advantage of the bag according to the invention is that it has improved durability in transport and storage. Thus, with thi...
