Description

Technical Field

[0001] This utility model relates to the field of packaging bottle technology, and more specifically to a food packaging bottle with good sealing performance. Background Technology

[0002] Modern food packaging bottles typically employ a multi-layered composite structure, mainly comprising the following parts: Bottle cap: Mostly made of PP or PE material, equipped with anti-counterfeiting and leak-proof designs. Bottle neck: Standardized threaded or snap-fit ​​structure, some equipped with aluminum foil sealing film to extend shelf life. Bottle body: The main material is mostly PET, HDPE, or glass, with a lightweight design balancing pressure resistance and cost. Some products incorporate a barrier layer to block oxygen and ultraviolet rays. Bottle bottom: Grooved or petal-shaped bottom design to enhance stability, some including recycling symbols.

[0003] Inadequacies of existing technology: The opening of existing food packaging bottles is too small, making it difficult to remove food from the bottle. In addition, the existing packaging bottles are sealed by threads, which not only cannot guarantee the sealing effect but also makes it inconvenient for users to open. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a food packaging bottle with good sealing performance to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a food packaging bottle with good sealing performance, comprising a packaging bottle assembly, a sealing component provided at the top of the packaging bottle assembly, the packaging bottle assembly comprising a lower packaging bottle body, an upper packaging bottle body fixedly connected to the top of the lower packaging bottle body, a first annular groove formed at the top of the lower packaging bottle body, a first arcuate groove formed at the bottom of the first annular groove, a second arcuate groove formed at the bottom of the first arcuate groove, an annular telescopic groove formed at the top of the upper packaging bottle body, a spring fixedly connected to the bottom of the annular telescopic groove, a limiting annular plate fixedly connected to the top of the spring, and a lifting ring fixedly connected to the top of the limiting annular plate.

[0006] Furthermore, the sealing assembly includes a sealing sleeve, a sealing ring fixedly connected to the bottom of the sealing sleeve, a second annular groove formed on the top of the inner side of the sealing sleeve, a sealing gasket fixedly connected to the top of the inner side of the sealing sleeve, a sealing arc plate fixedly connected to the bottom of the sealing ring, and a sealing arc-shaped notch formed on the top of the sealing arc plate.

[0007] Furthermore, the cross-sectional dimensions of the inner side of the annular telescopic groove are clearance-fitted with the cross-sectional dimensions of the limiting annular plate, and the cross-sectional dimensions of the top opening of the annular telescopic groove are clearance-fitted with the cross-sectional dimensions of the lifting ring.

[0008] Furthermore, there is a clearance fit between the inner and outer diameters of the second annular groove and the inner and outer diameters of the second annular groove, and there is a clearance fit between the outer diameter of the sealing gasket and the inner diameter of the inner side of the packaging bottle.

[0009] Furthermore, the diameters of the inner and outer sides of the first annular groove and the diameters of the inner and outer sides of the sealing ring are in clearance fit, and the included angles on both sides of the first arc-shaped groove are the same as the included angles on both sides of the sealing arc plate.

[0010] Furthermore, the sum of the included angles on both sides of the sealing arc plate and the included angles on both sides of the sealing arc notch is the same as the included angles on both sides of the second arc groove.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. When sealing food, the present invention places the food to be sealed and preserved inside the lower body of the packaging bottle, then covers the outer side of the packaging bottle assembly, inserts the sealing ring and sealing arc plate into the inner side of the first annular groove, aligns the sealing arc plate with the first arc groove, and then contacts the bottom of the second arc groove with the bottom of the sealing arc plate. Then, the sealing assembly is rotated clockwise until it can no longer rotate, thus achieving the sealing and preservation of food. It is easy for users to operate, and users can quickly seal and open the food.

[0013] 2. When sealing food, the lifting ring is inserted into the inner side of the second annular groove. Then, with the continuous advancement and cooperation of the packaging bottle assembly and the sealing assembly, the lifting ring and the limiting annular plate will descend, thereby compressing the spring. Under the action of the spring's own rebound coefficient, the limiting annular plate and the lifting ring will have upward potential energy, which can effectively separate the space inside the packaging bottle assembly from the space outside, so as to ensure the sealing effect.

Then the sealing ring 204 and the sealing arc plate 205 are inserted into the inside of the first annular groove 102, and then the sealing arc plate 205 is aligned with the first arc groove 103. Then the bottom of the sealing arc plate 205 contacts the bottom of the second arc groove 104. Then the sealing component 2 is rotated clockwise until the sealing component 2 can no longer rotate, thus achieving the sealing and preservation of food. This method is easy for users to operate, and users can quickly seal and open food.

[0022] In a preferred embodiment, the sealing assembly 2 includes a sealing sleeve 201, a sealing ring 204 fixedly connected to the bottom of the sealing sleeve 201, a second annular groove 202 formed on the top of the inner side of the sealing sleeve 201, a sealing gasket 203 fixedly connected to the top of the inner side of the sealing sleeve 201, a sealing arc plate 205 fixedly connected to the bottom of the sealing ring 204, and a sealing arc notch 206 formed on the top of the sealing arc plate 205. When sealing food, the lifting ring 109 is inserted into the inner side of the second annular groove 202. Then, with the continuous pushing and cooperating of the packaging bottle assembly 1 and the sealing assembly 2, the lifting ring 109 and the limiting annular plate 108 will descend, thereby compressing the spring 107. Under the action of the spring 107's own rebound coefficient, the limiting annular plate 108 and the lifting ring 109 have upward potential energy, which can effectively separate the space inside the packaging bottle assembly 1 from the space outside, so as to ensure the sealing effect.

[0023] In a preferred embodiment, the cross-sectional dimensions of the inner side of the annular expansion groove 106 are clearance-fitted with the cross-sectional dimensions of the limiting annular plate 108, and the cross-sectional dimensions of the top opening of the annular expansion groove 106 are clearance-fitted with the cross-sectional dimensions of the lifting ring 109.

[0027] The working principle of this utility model is as follows: When sealing food, the food to be sealed and preserved is placed inside the lower bottle body 101 of the packaging bottle, and then the sealing component 2 is placed over the outer side of the packaging bottle component 1. Then, the sealing ring 204 and the sealing arc plate 205 are inserted into the inner side of the first annular groove 102, and then the sealing arc plate 205 is aligned with the first arc groove 103, and then the bottom of the sealing arc plate 205 contacts the bottom of the second arc groove 104. Then, the sealing component 2 is rotated clockwise until the sealing component 2 can no longer rotate, thus achieving the sealing and preservation of food. It is also convenient for users to operate, and users can quickly seal and open food.

[0028] When sealing food, the lifting ring 109 is inserted into the inner side of the second annular groove 202. Then, with the continuous advancement and cooperation of the packaging bottle assembly 1 and the sealing assembly 2, the lifting ring 109 and the limiting annular plate 108 will descend, thereby compressing the spring 107.
