Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of food packaging, in particular to a four-side sealed rice bag with a handle structure. Background Art
[0002] Rice, also known as paddy, is a food made from rice grains through processes such as cleaning, husking, milling, and finished product arrangement. As one of the main foods of the Chinese people, its production and production-related technologies are constantly improving to adapt to the changing needs of actual production. For example, in order to grasp and move rice packaging bags, the existing technology discloses a handle structure with a lifting hole, a handle structure with a lifting ring, etc. as a convenient structure for users to lift and move rice packaging bags.
[0003] However, due to the limitations of material thickness and cost, when using a handle structure with a lifting hole to lift heavy objects, the lifting hole is easily damaged. Secondly, the handle structure with a lifting ring needs to be installed below the packaging bag line, which can easily delay production efficiency and increase material usage, thereby increasing production costs. Therefore, in summary, the handle structure of rice packaging bags disclosed in the prior art has shortcomings and needs further improvement. Utility Model Content
[0004] In view of the deficiencies of the prior art, the present invention provides a four-side sealed rice bag with a handle structure, which solves the problems raised by the above-mentioned background technology.
[0005] The utility model provides the following technical solution: a four-side sealed rice bag with a handle structure, comprising a four-side sealed rice bag, a first clearance groove and a handle assembly being provided at the top of the four-side sealed rice bag, a gripping space being formed between the bottom structure of the handle assembly and the first clearance groove;
[0006] The handle assembly comprises a first composite handle structure, which is composed of a thickened plastic film and an outer protective plastic film covering the surface of the thickened plastic film.
[0007] The first composite handle structure is integrally formed with the top structure of the four-side sealed rice bag, the thickness of the thickened plastic film is greater than the thickness of the outer protective plastic film, and the first composite handle structure can increase or decrease the handle strength according to the actual weight of the item to ensure that the heavy object will not be damaged. Secondly, a plastic film handle that can withstand heavy objects can be directly made during the bag making process of the machine, avoiding the need to reinstall the handle on the single four-side sealed rice bag 1 after it leaves the production line, thereby improving efficiency. Furthermore, the structural shape of the first composite handle structure itself can also be changed into different shapes, which is both practical and can increase the aesthetics of the product. Finally, compared with existing buckles or rings, the first composite handle structure can reduce the amount of plastic used and is more environmentally friendly.
[0008] Selected, both sides of the front end of the four-side sealed rice bag are fixedly connected with extension straps, and one side of the two extension straps is provided with a second give way groove and a second composite handle structure, an auxiliary gripping space is formed between the one side structure of the second composite handle structure and the second give way groove, the structure of the second composite handle structure is the same as that of the first composite handle structure, and the second composite handle structure and the extension strap are also integrally formed, and the side gripping assembly is composed of the extension strap, the second give way groove, and the second composite handle structure. Then, after the two sets of side gripping assemblies are used with the four-side sealed rice bag, the user can be provided with gripping conditions for two people to lift the bag.
[0009] The corners of the two extension bands and the corners of the top of the four-side sealed rice bag are set to rounded structures to improve the aesthetics, and the two extension bands can be folded to the inside of both sides of the four-side sealed rice bag respectively, further expanding the use effect.
[0010] Preferably, the handle assembly includes a third composite handle structure, and the third composite handle structure is integrally formed with the top structure of the four-side-sealed rice bag. The third composite handle structure is an inverted V-shaped structure and can be expanded outside the top of the first give way groove. The composition structure of the third composite handle structure is the same as that of the first composite handle structure. After the third composite handle structure is expanded, the contact force area with the palm of the user when holding it will be increased, thereby improving and enhancing the comfort during use.
[0011] The third composite handle structure is selectively provided with through-shaped clearance holes on both sides, and reinforcement rods are clamped inside the two clearance holes. The reinforcement rods increase the stability and structural strength of the expansion of the third composite handle structure, and then maintain the third composite handle structure in a large-area state after expansion for a long time, thereby improving the comfort of use.
[0012] The surface of the four-side sealed rice bag is fixedly connected with a semi-elastic sleeve, the top of the semi-elastic sleeve is an open structure, and a placement space for accommodating the reinforcing rod is formed between the inner wall of the semi-elastic sleeve and the surface of the four-side sealed rice bag, thereby performing targeted storage processing on the reinforcing rod when not in use, avoiding loss of the reinforcing rod and facilitating subsequent recycling and reuse.
