Abstract
Description
Technical Field
[0001] This utility model relates to the field of blow-molded products, and in particular to a blow-molded bottle structure in which the handle and the inner cavity of the bottle are not connected. Background Technology
[0002] Most existing medium and large blow-molded bottles, such as soy sauce bottles, gasoline bottles, and laundry detergent bottles, use an interconnected design between the handle and the bottle body cavity. However, because the handle and the bottle body are connected, the connection point is prone to stress concentration, which may lead to cracking after long-term use.
[0003] In addition, when storing corrosive, high-pressure, or high-temperature liquids, these liquids may seep into the handle, potentially causing harm to the user. Even if they do not, for long-term items such as soy sauce bottles and cooking oil bottles, the cavity in the handle is easily contaminated and breeds bacteria.
[0004] Furthermore, from a manufacturing perspective, blow molding the handle cavity is quite challenging, requiring complex airflow designs to avoid defects such as uneven wall thickness and collapse. If the handle and the bottle's inner cavity are not connected, it means their inner cavities can be blow molded independently, reducing mold processing difficulty and cost, and effectively improving product yield. Additionally, in the current climate of rising prices, this is also a way to increase product price while maintaining the same external bottle volume but reducing the contents. Summary of the Invention
[0005] The main purpose of this utility model is to provide a blow-molded bottle structure in which the handle and bottle body are not connected, by using a separate blow molding method to blow mold the bottle structure. This avoids the influence of the contents inside the bottle on the bottle body, and can improve the structural strength and durability of the bottle body while simplifying the manufacturing process.
[0006] This utility model proposes a blow-molded bottle structure with a handle and bottle body cavity that are not connected, including a handle and a bottle body, wherein the handle and the bottle body are respectively provided with a handle cavity and a bottle body cavity.
[0007] The handle is provided with handle connectors at both ends, and the handle and the bottle body are connected by the handle connectors. The handle cavity and the bottle body cavity are separated by the handle connectors.
[0008] Preferably, the top of the bottle body is provided with a bottle opening, and the cavity of the bottle body is connected to the outside through the bottle opening.
[0009] Preferably, a counterweight is provided inside the handle cavity, which can enhance the stability of the grip.
[0010] Preferably, the handle cavity is provided with a heat insulation structure, which can improve the comfort of holding.
[0011] Preferably, the handle and the bottle body are integrally formed.
[0012] The beneficial effects of the blow-molded bottle structure with a non-connected handle and inner cavity are as follows:
[0013] By separating the inner cavity of the bottle body and the inner cavity of the handle, stress concentration points can be avoided at the connection between the handle and the bottle body, thereby extending the service life.
[0014] The performance of the bottle structure can be improved by setting counterweights or heat insulation structures inside the handle cavity.
[0015] Since the inner cavity of the bottle body and the inner cavity of the handle do not need to be connected, different air needles can be used for blow molding of the bottle body and the handle, which simplifies the manufacturing process and reduces the processing difficulty and cost of the mold.
[0016] By separating the inner cavity of the bottle body and the inner cavity of the handle, it is possible to effectively prevent the contents of the bottle from leaking or becoming contaminated. Attached Figure Description
