Description

Technical Field

[0001] The utility model relates to the technical field of spray bottles and vacuum bottles, in particular to a packaging bottle using a large-capacity positioning spray pump. Background Art

[0002] A vacuum spray bottle refers to a bottle with a spray pump. By pressing the spray pump, you can control the spray bottle to spray out mist liquid. It is often used to store liquids such as perfume, hairspray, water, and detergent.

[0003] The rebound device of the existing spray pump is mainly completed by a spring. The spray pump spring is generally a metal spring. The material cost of the metal spring is relatively high and it is easy to rust after long-term use, which not only affects the feel of use, but also produces chemical substances to contaminate the liquid (perfume, hair spray, water, detergent).

[0004] The spray hole of the existing vacuum bottle is flush with the spray piece, and a corresponding outer cover is required after spraying to prevent liquid from overflowing. The outer cover is a separate component that is covered on the vacuum bottle. Since the vacuum bottle is small in size, it is convenient to carry when going out. When the vacuum bottle is placed in a bag or a bag, the outer cover is easily separated from the bottle body by external force, and the head cap is easily exposed. When the head cap without the protection of the outer cover is squeezed, the liquid in the vacuum bottle will be pumped out, causing waste and also dirtying the bag or the bag. Utility Model Content

[0025] Please refer to Figure 1-4A vacuum bottle using a large-capacity positioning spray pump 3 includes a bottle body 1, a protective cover 2 threadedly connected to the bottle body 1, and a spray pump 3 installed in the protective cover 2. The spray pump 3 includes a pump core 4, a head cap 5 installed at one end of the pump core 4, and a straw 6 installed at the other end of the pump core 4. The straw 6 extends into the bottle body 1. The pump core 4 includes a main body 7, a liquid outlet rod 8 and an elastic element 9. The pump core 4 also includes a valve needle, a piston, a water sealing plate, etc. The valve needle, the piston, the water sealing plate, etc. in this embodiment are commonly used components of the pump core 4, so these components will not be described in detail here.

[0026] Specifically, the elastic element 9 is sleeved on the liquid outlet pipe and is located between the main body 7 and the liquid outlet rod 8. The elastic element 9 includes an upper limit ring 10, a lower limit ring 11 and two spirals 12. The upper limit ring 10, the lower limit ring 11, the spiral 12 and the connector are an integrated structure. The upper limit ring 10 is in contact with the liquid outlet rod 8, and the lower limit ring 11 is connected to the main body 7 of the liquid outlet rod 8. One end of the spiral 12 is connected to the upper limit ring 10, and the other end is connected to the lower limit ring 11.

[0027] The two spiral bodies 12 are arranged opposite to each other, and the connection point between one spiral body 12 and the upper limit ring 10 and the connection point between the other spiral body 12 and the upper limit ring 10 are 180° apart, and the connection point between one spiral body 12 and the lower limit ring 11 and the connection point between the other spiral body 12 and the lower limit ring 11 are 180° apart. The elastic element 9 is a full plastic part, made of TPE or TPEE material, with a simple structure and convenient manufacturing, thereby playing the role of a spring, replacing the traditional metal spring, realizing full plastic material, and compared with the traditional metal spring, it ensures that the vacuum pump can be used normally while not being corroded or contaminated by materials. Two spiral bodies 12 are designed between the upper limit ring 10 and the upper limit ring 10, and the two spiral bodies 12 are designed in a 180° symmetrical position, with consistent structural specifications and uniform elastic force, so they have good stability and are not easy to damage. And the two spiral bodies 12 are both single-strip structures, leaving a larger spacing compared to traditional metal springs, which reduces the use of raw materials and reduces the complexity of the mold structure, making it easier to demould.

[0028] Specifically, a plurality of equally spaced convex ribs 13 are provided on the inner wall of the lower limit ring 11, and a convex rib groove 14 is formed between two adjacent convex ribs 13. A plurality of equally spaced limit strips 15 are provided on the outer wall of the liquid outlet rod 8. The limit strips 15 are located in the convex rib groove 14, and the limit strips 15 are matched with the convex ribs 13. When the elastic element 9 is pressed, it can be ensured that the elastic element 9 and the liquid outlet rod 8 will only move up and down and will not twist left and right.

[0029] Specifically, a partition 16 is provided inside the protective cover 2, and a through hole is provided in the middle of the partition 16. The partition divides the protective cover 2 into two parts, including a head cap movable cavity 17 and a pump core fixed cavity 18. The head cap movable cavity 17 and the pump core fixed cavity 18 are connected. The head cap 5 is located in the head cap movable cavity 17 and is not higher than the protective cover 2. That is, the head cap 5 is hidden in the protective cover 2 whether it is used or not, which can well protect the head cap 5 and avoid liquid leakage due to external force during placement. The pump core 4 is located in the pump core fixed cavity 18.

[0030] A first U-shaped groove 19 and a second U-shaped groove 20 are provided on the top of the protective cover 2. The first U-shaped groove 19 and the second U-shaped groove 20 are arranged opposite to each other. The liquid outlet pipe of the head cap 5 is located in the first U-shaped groove 19. The depth of the first U-shaped groove 19 is about three-fifths of the head cap active cavity 17. The second U-shaped groove 20 is cut obliquely from top to bottom to facilitate the user to press the head cap 5.

[0031] The utility model realizes the concept of being independent without an outer cover through the design of the protective cover 2. When in use or not in use, the head cap 5 is hidden in the head cap movable cavity 17 of the protective cover 2, thereby preventing the protective cover 2 from easily falling off the bottle body 1 and causing secondary overflow pollution. In addition, the fully plastic elastic element 9 ensures that the spray pump 3 can be used normally without being corroded or contaminating the liquid.

[0032] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
