Description

Technical Field

[0001] This utility model relates to the field of cosmetic container technology, specifically a dispenser that allows for quick-connection and press-to-dispense quantitative liquid. Background Technology

[0002] Cosmetics: Conditioners (excluding soap) used on the human body to beautify, preserve, or alter a person's appearance (e.g., for performance purposes), or for cleansing, dyeing, rubbing, correcting, or protecting the skin, hair, nails, eyes, or teeth. Currently, some cosmetics use liquids such as lotions or serums. To ensure effectiveness, different components are stored separately. When using, a certain amount of the liquid is taken from a dispensing bottle and poured into a smaller bottle, mixed with the liquid in the smaller bottle, and then used. Common dispensing methods include: 1. Direct bottle-to-bottle pouring; 2. Syringe aspiration and subsequent conversion; 3. Dropper aspiration and subsequent conversion. Method 1 is quick but prone to leakage. Methods 2 and 3 achieve precise dispensing, but require container conversion, leading to residual liquid consumption. These methods are cumbersome and inconvenient. Therefore, a quick-connect, press-to-dispense dispensing device is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a dispensing device that allows for quick-connection and press-to-dispense quantitative liquid, thus solving the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a quick-connect, press-to-dispense dispenser, comprising an outer container and a bottle, the top of the outer container being threadedly connected to a shoulder cap, a locking cap being provided on the outer side of the shoulder cap, a PP inner container being placed inside the outer container, a threaded cap being provided on the outer side of the top of the PP inner container, the threaded cap being located inside the shoulder cap and the locking cap, a pressure cap being provided on the top of the PP inner container and below the threaded cap, and a silicone sealing element being provided inside the pressure cap.

[0005] Preferably, a dust cover is fitted on the outer side of the lock cover.

[0006] Preferably, a spring portion is provided at the bottom of the PP inner container.

[0007] Preferably, a nozzle is threadedly connected to the top of the bottle, the bottom end of the nozzle extends into the inside of the bottle, and a bottle cap is fitted onto the top of the nozzle.

[0008] Preferably, a capacity scale portion is provided on one side of the outer container, and the surface of the capacity scale portion is provided with a plurality of scales.

[0009] Preferably, a scraper plug is provided on the outside of the discharge pipe at one end of the silicone seal.

[0010] Preferably, the top of the scraper plug has four vent grooves, the surface of the lock cover has a through hole, the surface of the shoulder cover has an unlocking mark, and the surface of the shoulder cover and the side of the unlocking mark has a locking mark. Both the unlocking mark and the locking mark are matched with the through hole.

[0011] This utility model provides a dispenser for quick-connection, press-to-dispense quantitative liquid, which has the following advantages:

[0012] This quick-connect, press-to-dispense dispenser features a PP inner container, a pressure cap, and a silicone seal. The bottle is connected to a screw cap. Pressing the dispenser vertically causes the inner container to shrink, increasing internal pressure. Liquid then forces its way through the cross-shaped opening of the silicone seal and flows into the bottle. The silicone seal expands and contracts with pressure changes, effectively preventing spillage and oxidation without external pressure. A few presses vertically downwards complete the dispensing process, avoiding the need for container switching and the resulting residue loss and cumbersome operation of other dispensing methods on the market.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1 to 12 This utility model provides a technical solution: a quick-connect, press-to-dispense dispenser, including an outer container 1 and a bottle 13. The top of the outer container 1 is threaded with a shoulder cap 8, and a locking cap 9 is provided on the outside of the shoulder cap 8. A PP inner container 3 is placed inside the outer container 1. A threaded cap 7 is provided on the outside of the top of the PP inner container 3. The threaded cap 7 is located inside the shoulder cap 8 and the locking cap 9. A pressure cap 5 is provided on the top of the PP inner container 3 and below the threaded cap 7. A silicone sealing element 6 is provided inside the pressure cap 5.

[0029] A dust cover 10 is fitted on the outside of the lock cover 9.

[0030] A spring part 4 is provided below the inner container 3 of the PP. The spring part 4 is a ring-shaped spiral spring, which has the function of shrinking and rebounding when squeezed by external force.

[0031] A nozzle 12 is threadedly connected to the top of the bottle 13. The bottom end of the nozzle 12 extends into the inside of the bottle 13, and a bottle cap 11 is fitted onto the top of the nozzle 12.

[0032] The outer container 1 has a capacity scale section 2 on one side. The surface of the capacity scale section 2 has several scales. When the pressure is applied so that the convex ring on the shoulder of the inner PP container 3 is flush with the scale lines on the surface of the capacity scale section 2 on the front and back sides of the outer container 1, the dispensing volume of 5ml, 10ml and 15ml can be controlled accordingly.

[0033] A scraper plug 14 is provided on the outside of the discharge pipe at one end of the silicone seal 6. The scraper plug 14 can effectively solve the problem of material residue on the outer wall of the channel.

[0034] The top of the scraper plug 14 has four vent grooves 18, the surface of the lock cover 9 has a through hole 17, the surface of the shoulder cover 8 has an unlocking mark 15, and the surface of the shoulder cover 8, located on one side of the unlocking mark 15, has a locking mark 16. Both the unlocking mark 15 and the locking mark 16 are matched with the through hole 17.

[0035] In summary, this quick-connect, press-to-dispense dispenser is used by removing the dust cover 10, inverting the dispenser, and operating it vertically. Unscrew the nozzle 12 from the top of the bottle 13, then align the bottle 13 counter-clockwise with the threaded connector on the cap 7. Turn the locking switch clockwise to the unlocked mode; the unlock indicator 15 will then be visible to the user through the through-hole 17. Pressing the dispenser vertically causes the inner volume of the PP inner container 3 to shrink, increasing the internal pressure. The liquid inside the inner container 3 squeezes through the cross hole of the silicone seal 6 and flows downward into the bottle 13. The silicone seal 6 expands and contracts with pressure changes, effectively preventing the material from overflowing and oxidizing without external pressure. Air is discharged through the vent 18. After filling, turn the cap 9 to the locked position. At this time, the lock mark 16 can be seen by the user through the through hole 17. Then, turn clockwise to remove the bottle 13, and then screw the nozzle 12 back onto the outside of the top of the bottle 13 to complete the refilling operation.
