Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tube feeding containers, in particular to a composite plastic sterilization bottle. Background Art
[0002] Tube feeding is an effective method of enteral nutrition support for patients who are unable to take in enough nutrition by mouth. This method delivers fluid nutrients through a tube feeding bottle or syringe to ensure that the patient gets enough energy and nutrients.
[0003] The product is currently packaged in a composite plastic bottle, the outside of which is designed with an external thread and an anti-theft ring structure to facilitate the screwing of the bottle cap.
[0004] In the manufacturing process of composite plastic bottles, the softened plastic raw material is blow-molded in a mold using compressed air, resulting in internal threads and grooves for the anti-theft ring appearing at corresponding positions on the inner wall of the bottle mouth when the external threads and the anti-theft ring of the bottle mouth are formed.
[0005] Given the production characteristics of current liquid products, some foam or trace amounts of liquid may remain in the groove. Specifically, the area from the bottleneck to the bottle mouth is not submerged in liquid, but after sealing, it becomes a gas-containing space, exposing the foam or liquid remaining in the groove to the air. Over time, this may cause the foam or liquid to lose moisture and produce gel, and a filament will form along with the groove structure. Such filaments may fall into the liquid due to vibration during transportation and handling, and gel filaments that may be mistaken for foreign matter can be observed from the bottle. The filaments formed by the foam or liquid in the groove may be mistaken for foreign matter in the product, and this problem must be solved to avoid causing user concern.
[0006] In view of this problem, it is necessary to consider an optimized design scheme based on the product container structure to eliminate the possibility of foam or liquid forming filaments on the uneven surface of the inner wall of the bottle, thereby improving the user experience of the product. Utility Model Content
[0007] The utility model aims to provide a composite plastic sterilization bottle to solve the technical problem that foam or trace liquid is easily left on the inner wall of the bottle mouth of the existing composite plastic sterilization bottle, resulting in the formation of gel filaments.
[0008] To achieve the above purpose, the specific technical solution of a composite plastic sterilization bottle of the utility model is as follows:
[0009] A composite plastic sterilization bottle comprises a bottle body and a bottle mouth formed integrally with the bottle body above the bottle body, the outer wall of the bottle mouth is provided with an external thread and an anti-theft ring, the anti-theft ring is located below the external thread, the inner wall of the bottle mouth is a smooth and flat cylindrical arc surface, one group of opposite sides of the bottle body is provided with flat cut surfaces for facilitating collection and stacking, the other group of opposite sides of the bottle body is provided with an inwardly concave arc surface, and the bottom of the bottle body is concave upward to form a through groove for connecting a hook.
[0010] The inner wall of the bottle mouth adopts a smooth and flat cylindrical arc surface, which effectively reduces the possibility of foam or liquid generated during the production process being retained in the groove, thereby reducing the risk of forming gel filaments.
[0011] The bottle is designed with ease of use in mind, with a set of opposite sides configured with flat cut surfaces, making it easy to collect and stack the bottles, improving storage efficiency and space utilization.
[0012] The structure of the external thread and the anti-theft ring is arranged on the outer wall of the bottle mouth, which not only facilitates the screwing of the bottle cap, but also the position of the anti-theft ring helps to improve the safety of the product.
[0013] The through groove at the bottom of the bottle forms a structure for connecting a hook, which increases the versatility of the product and makes it easier to hang and carry.
[0014] Furthermore, convex ridges are extended inwardly from the groove walls on both sides of the through groove, and a clamping groove for clamping the hook is formed between the convex ridges and the groove bottom of the through groove.
[0015] The clip grooves formed by the ridges extending inward from the groove walls on both sides of the through groove provide a stable clamping structure for the hook. This design effectively prevents the hook from accidentally falling off during hanging or carrying, improving the portability and practicality of the bottle. The hook is clamped in the clip groove, which increases the firmness of the overall connection and ensures that the hook can be reliably fixed during carrying, hanging or other usage scenarios, thereby improving the practicality of the product and user experience.
[0016] The composite plastic sterilization bottle provided by the utility model has the following advantages:
[0017] First, the grooves on the inner wall of the bottle are eliminated. The smooth and flat cylindrical arc surface of the inner wall of the bottle mouth reduces the risk of foam or liquid being retained in the grooves during the production process, ensures the uniformity of the solution in the product bottle, eliminates adverse factors, effectively prevents the formation of gel filaments, and improves product quality and hygiene level.
[0018] Secondly, the flat surface and the inward-concave surface in the bottle design respectively provide a surface for easy collection and stacking and a specific depression for forming a stable structure. The concave surface is also convenient for hand holding and not easy to fall off, which improves the product's convenience of use and storage efficiency.
[0019] Finally, the bottom slot design not only provides a convenient connection point for the hook, but also enhances the stability of the hook through the clamping groove formed between the ridge and the bottom of the slot, making the bottle more suitable for hanging and carrying, and improving the practicality and portability of the product. Overall, these design elements work together to effectively improve the functionality, hygiene and practicality of the composite plastic sterilization bottle. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0026] See also Figures 1 to 4 The utility model provides a composite plastic sterilization bottle, comprising a bottle body 20 and a bottle mouth 30 located above the bottle body 20 and integrally formed therewith, the outer wall of the bottle mouth 30 is provided with an external thread 31 and an anti-theft ring 32, the anti-theft ring 32 is located below the external thread 31, the inner wall of the bottle mouth 30 is a smooth and flat cylindrical arc surface 33, a group of opposite sides of the bottle body 20 are provided with flat cut surfaces 21 for easy collection and stacking, and another group of opposite sides of the bottle body 20 are provided with an arc convex surface 25, the middle area on the arc convex surface 25 is concave inwardly to form an arc concave surface 22, and the bottom of the bottle body 20 is concave upward to form a through groove 23 for connecting a hook.
[0027] The inner wall of the bottle mouth 30 adopts a smooth and flat cylindrical arc surface 33, which effectively reduces the possibility of foam or liquid generated during the production process being retained in the groove, thereby reducing the risk of forming gel filaments.
[0028] The design of the bottle body 20 takes into account ease of use. The arc concave surface 22 is convenient for handholding and not easy to fall off. A set of opposite sides are provided with flat cut surfaces 21, making it easy to collect and stack the bottles, thereby improving storage efficiency and space utilization.
[0029] The structure of the external thread 31 and the anti-theft ring 32 is arranged on the outer wall of the bottle mouth 30, which not only facilitates the screwing of the bottle cap, but also the position of the anti-theft ring 32 helps to improve the safety of the product.
[0030] The through groove 23 at the bottom of the bottle body 20 forms a structure for connecting a hook, which increases the versatility of the product and facilitates hanging and carrying.
[0031] Furthermore, ridges 24 extend inwardly from the groove walls on both sides of the through groove 23 , and a clamping groove for clamping the hook is formed between the ridges 24 and the groove bottom of the through groove 23 .
[0032] The clamping groove formed by the ridges 24 extending inwardly from the groove walls on both sides of the through groove 23 provides a stable clamping structure for the hook.

[0033] Eliminating the grooves on the inner wall of the bottle does not change the bottle's external structure, and does not affect the bottle's sealing and capping. It eliminates the place or environment where the foam (even if there is) or liquid in the bottle can form filaments. It eliminates the prerequisite for the product gel to form filaments, ensures the uniformity of the solution in the product bottle, and eliminates adverse factors.
[0034] In summary, the composite plastic sterilization bottle provided by the utility model optimizes the key features of the product by eliminating the groove design on the inner wall of the bottle, thereby producing a series of positive effects.
[0035] By using a smooth cylindrical arc surface on the inner wall of the bottle mouth, the groove is successfully eliminated, creating a flatter internal environment. This design avoids the problem of foam or a small amount of liquid generated during the production process being retained in the groove. Even if there is foam, it will not form filaments, because without the existence of the groove, there is no condition for exposure to the air in the bottle, thus avoiding the possibility of filament formation.
[0036] Eliminating the grooves effectively prevents the product from gelling and forming filaments. This helps ensure the uniformity of the solution in the bottle, improving the quality and reliability of the product. Overall, this optimized design eliminates undesirable factors, provides a more stable and hygienic container structure for the product, and helps ensure that consumers get a high-quality, consistent product experience.
