The self-standing spout is a flexible packaging bag made of plastic film, suitable for holding beverages, jelly, and fruit granules. When the bag contains contents, the weight of the contents causes the bag to open, allowing it to stand upright on a surface, which is known as self-supporting.
Stand-up Spout A flexible packaging bag made of plastic film, which can be used to hold beverages, jelly, and fruit granules. When the bag contains contents, the weight of the contents causes the bag to open, allowing it to stand upright on a platform, hence the term self-supporting. Stand-up spout bags are typically formed by folding a bottom sheet at the fold line, clamped between the lower ends of two main sheets forming the body above it, with the two main parts heat-sealed together with the bottom sheet at the side edges. After filling with contents, the bottom of the vertical bag opens due to the weight of the contents, forming a stable base. Additionally, this packaging bag combines materials with various properties to enhance breathability, moisture permeability, oil resistance, water resistance, and chemical resistance, thereby providing resistance against insects, dust, microorganisms, light, odors such as fragrance and taste, as well as heat resistance, cold resistance, impact resistance, and good mechanical strength and processing suitability.
However, when used for beverages, juices, and other foods, straws are initially used, which require piercing the bag before drinking, making it very troublesome and inconvenient. The purpose of this utility model's stand-up spout is to provide a bottom-inserted spout to solve the aforementioned problems. To achieve this purpose, this utility model provides the following technical solution: a bottom-inserted Stand-up Spout spout, including a spout bag body, with a sealed top on the spout bag body, sealed edges on the left and right sides of the spout bag body, a wrist located between the lower edge of the top and the right edge, a fixing ring between the left edge of the top and the left edge, the fixing ring's inner cavity inserted with the spout, the spout's outer wall having external threads, the spout inserted into the inner cavity of the spout cap, the inner wall of the spout cap having internal threads, a folded bottom located on the lower middle part of the spout bag body, and a sealed bottom below the folded bottom. The spout and spout cap are connected by matching external and internal threads. The spout bag body is made of a three-layer plastic film spout bag, with no fewer than two sealed edges.
Compared with the prior art, the beneficial effect of this utility model is: the bottom-inserted Stand-up Spout spout improves the production efficiency of the packaging bag through the spout, eliminating the need for additional manual sealing, and allows for large liquid packaging capacity. Through the composite of three layers of plastic film, the bottom is supported by the weight of the liquid itself, enabling it to stand stably like a plastic bottle, convenient to carry, more economical than plastic bottles, and easier for consumers to use. The stand-up spout bag is easier to pour or suck contents from and can be resealed and reopened. It can be regarded as a combination of a stand-up bag and a regular bottle mouth. This type of stand-up bag is commonly used for packaging daily necessities, holding liquids, colloids, and semi-solid products such as beverages, shower gel, shampoo, ketchup, edible oil, and jelly.
