Description

Technical Field

[0001] This utility model relates to the field of daily chemical product packaging technology, and in particular to a self-sealing dispenser for shampoo powder. Background Technology

[0002] Shampoo powder, as a solid shampoo product, is increasingly favored by consumers due to its portability, lack of risk of liquid leakage, and concentrated ingredients. Currently, shampoo powder products on the market are generally packaged in traditional hard plastic bottles or soft plastic bags. The most common packaging form is an open-top bottle structure consisting of a bottle body and a cap. When using it, users need to unscrew or pull off the cap and pour out the shampoo powder by tilting or shaking the bottle.

[0003] The existing packaging methods described above have significant drawbacks, primarily in their insufficient moisture protection and sealing performance. Sealing relies heavily on manual operation: the sealing effect depends entirely on the user's timely and accurate tightening or fastening of the cap after use. In real-world scenarios, especially in high-humidity environments such as bathrooms, users may fail to fully tighten the cap due to haste, negligence, or slippery hands, resulting in a poor seal. In such cases, the water-vapor-rich air in the bathroom environment will rapidly and in large quantities enter the bottle, coming into full contact with the remaining shampoo powder.

[0004] When shampoo powder absorbs moisture from the air, its powder particles clump together, affecting not only usability but also compromising its original quality and effectiveness. Some active ingredients in shampoo powder may undergo hydrolysis or oxidation in humid environments, reducing their cleansing and conditioning efficacy. Humid environments also provide conditions for microbial growth, potentially causing product spoilage and posing a potential risk to the user's scalp health. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a self-sealing shampoo powder dispenser. This dispenser allows for convenient dispensing of shampoo powder during use and features an automatic and reliable air-sealing mechanism after each use, effectively protecting the shampoo powder inside the bottle, extending its shelf life, and ensuring its effectiveness and the user's health.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a self-sealing shampoo dispenser, comprising a bottle body with a bottle opening, including a positioning sleeve fixed to the bottle opening and a support frame fixed inside the bottle opening, the support frame including a sealing head and a guide strip connected to the bottom of the sealing head, the guide strip having a discharge gap between them, a discharge sleeve movably sleeved on the sealing head, the bottom of the discharge sleeve having a flexible sealing element, the inner wall of the flexible sealing element abutting against the sealing head, a reset elastic element being provided between the discharge sleeve and the bottle opening, the discharge sleeve being able to be pressed until the inner wall of the flexible sealing element abuts against the guide strip to expose the discharge gap. This self-sealing shampoo dispenser works by inverting the bottle and pressing the dispensing sleeve. The flexible seal moves upwards until the dispensing gap is exposed, allowing shampoo to flow out. Once sufficient shampoo has been dispensed, the sleeve is released, and the elastic return mechanism resets it, restoring the flexible seal to its original position against the sealing head and restoring the bottle's seal. The dispensing speed can be adjusted by changing the pressure applied to the sleeve. This self-sealing dispenser allows for convenient dispensing of shampoo and provides an automatic and reliable airtight seal after each use, effectively protecting the shampoo, extending its shelf life, and ensuring optimal performance and user health.

[0007] In the above technical solution, preferably, the discharge sleeve is provided with a limiting ring to limit the maximum extension height of the discharge sleeve, and the inner wall of the bottle, the support frame, or the reset elastic element is provided with a retaining ring to block the limiting ring. To facilitate assembly and prevent the discharge sleeve from detaching, this structure limits the maximum extension height of the discharge sleeve, ensuring that when not in use, the inner wall of the flexible seal abuts against the sealing head to seal the bottle.

[0008] In the above technical solution, preferably, the retaining ring is disposed on the reset elastic member.

[0009] In the above technical solution, preferably, the support frame includes a positioning ring, a bent connecting portion connected to the positioning ring, a guide strip connected to the bent connecting portion, and a sealing head. A movable gap is formed between the bent connecting portion and the guide strip for the discharge sleeve to move up and down. This structure allows for convenient positioning of the support frame, facilitates the positioning of the guide strip and the sealing head, and also limits the maximum insertion depth of the discharge sleeve.

[0010] In the above technical solution, preferably, the inner wall of the positioning sleeve is provided with a positioning protrusion ring, and the positioning ring for fixing the support frame is clamped between the positioning protrusion ring and the bottle mouth end face. This structure facilitates the fixing of the support frame.

[0011] In the above technical solution, preferably, the positioning protrusion ring is provided with a plurality of slots, and the positioning ring is provided with elastic buckles that are fixed to the slots. This structure can further improve the positioning stability of the positioning protrusion ring and the positioning ring, and the positioning sleeve and the support frame can be connected as a whole, with the support frame being able to be disassembled and assembled with the bottle body along with the positioning sleeve.

[0012] In the above technical solution, preferably, the reset elastic element is a tapered cylindrical elastic sleeve, one side of the cylindrical elastic sleeve abuts against the abutting surface on the discharge sleeve, and the other side of the cylindrical elastic sleeve abuts against the positioning sleeve.

[0013] In the above technical solution, preferably, the inner wall of the positioning sleeve is provided with a positioning protrusion ring, and the cylindrical elastic sleeve is provided with an annular positioning groove, with the positioning protrusion ring inserted into the annular positioning groove. This structure further improves the positioning stability of the reset elastic element.

[0014] In the above technical solution, preferably, the discharge sleeve is rotatably fitted onto the sealing head, the inner wall of the positioning sleeve is provided with a limiting rib, and the discharge sleeve is provided with an avoidance opening that matches the limiting rib. This structure allows the limiting rib and the avoidance opening to be misaligned by rotating the discharge sleeve when not in use, preventing accidental pressure on the discharge sleeve and thus avoiding opening of the discharge gap.

[0015] In the above technical solution, preferably, the discharge sleeve is provided with a positioning rib. When one side of the limiting rib abuts against the positioning rib, the limiting rib is aligned with the clearance opening. This structure allows for easy alignment of the positioning rib and the clearance opening by rotating the discharge sleeve to bring one side of the limiting rib abuts against the positioning rib when needed.

[0016] Compared with the prior art, this utility model has the following beneficial effects: When using this self-sealing shampoo dispenser, the bottle is inverted, and the dispensing sleeve is pressed to move the sleeve. The inner wall of the flexible seal moves upward until the dispensing gap is exposed, allowing the shampoo powder to be dispensed. After sufficient dispensing, the dispensing sleeve is released, and it resets under the action of the reset elastic element, causing the inner wall of the flexible seal to return to abut against the sealing head, restoring the seal of the bottle. The dispensing speed of the shampoo powder can be adjusted by changing the pressure applied to the dispensing sleeve. This self-sealing shampoo dispenser allows for convenient dispensing of shampoo powder during use, and its automatic and reliable air-sealing mechanism after each use effectively protects the shampoo powder inside the bottle, extends its shelf life, and ensures the effectiveness of use and the health of the user.

The dispenser includes a positioning sleeve 3 fixed to the bottle opening 2 and a support frame 4 fixed inside the bottle opening 2. The support frame 4 includes a sealing head 5 and guide strips 6 connected to the bottom of the sealing head 5. A discharge gap 7 is formed between the guide strips 6. A discharge sleeve 8 is movably sleeved on the sealing head 5. A flexible sealing element 9 is located at the bottom of the discharge sleeve 8. The flexible sealing element 9 is annularly fixed to the bottom of the discharge sleeve 8. The inner wall of the flexible sealing element 9 abuts against the sealing head 5. A reset elastic element 10 is provided between the discharge sleeve 8 and the bottle opening 2. The discharge sleeve 8 can be pressed until the inner wall of the flexible sealing element 9 abuts against the guide strips 6 to expose the discharge gap 7. When using this self-sealing shampoo dispenser, the bottle 1 is inverted, and the dispensing sleeve 8 is pressed to move it. The inner wall of the flexible sealing element 9 moves upward until the dispensing gap 7 is exposed, allowing the shampoo powder to be dispensed from the gap. After sufficient dispensing, the dispensing sleeve 8 is released, and it resets under the action of the reset elastic element 10, causing the inner wall of the flexible sealing element 9 to return to abut against the sealing head 5, restoring the seal of the bottle 1. The dispensing speed of the shampoo powder can be adjusted by changing the pressure applied to the dispensing sleeve 8 as needed. This self-sealing shampoo dispenser allows for convenient dispensing of shampoo powder during use, and its automatic and reliable air-sealing mechanism after each use effectively protects the shampoo powder inside the bottle, extends its shelf life, and ensures the effectiveness of use and the health of the user.

[0024] In this embodiment, a limiting ring 11 is provided on the discharge sleeve 8 to limit the maximum extension height of the discharge sleeve 8, and a retaining ring 12 is provided on the reset elastic member 10 to block the limiting ring 11. In order to facilitate assembly and prevent the discharge sleeve 8 from detaching, this structure can limit the maximum extension height of the discharge sleeve 8, and ensure that when not in use, the inner wall of the flexible sealing member 9 abuts against the sealing head 5 to seal the bottle body 1.

[0025] Of course, it is easy for those skilled in the art to understand that the retaining ring 12 can also be set on the inner wall of the bottle body 1 or on the support frame 4.

[0026] In this embodiment, the support frame 4 includes a positioning ring 13, a bent connecting portion 14 connected to the positioning ring 13, a guide strip 6 connected to the bent connecting portion 14, and a sealing head 5. A movable gap 15 is formed between the bent connecting portion 14 and the guide strip 6 to allow the discharge sleeve 8 to move up and down. In this embodiment, the bent connecting portion 14 is a bent connecting rod that corresponds one-to-one with the guide strip 6. This structure allows for easy positioning of the support frame 4, facilitates the positioning of the guide strip 6 and the sealing head 5, and also limits the maximum insertion depth of the discharge sleeve 8.

[0027] In this embodiment, a positioning protrusion 16 is provided on the inner wall of the positioning sleeve 3, and a positioning ring 13 for fixing the support frame 4 is sandwiched between the positioning protrusion 16 and the end face of the bottle mouth 2. This structure facilitates the fixing of the support frame 4.

[0028] In this embodiment, the positioning protrusion 16 is provided with a plurality of bayonet slots 17, and the positioning ring 13 is provided with elastic buckles 18 that are fixed to the bayonet slots 17. This structure can further improve the positioning stability of the positioning protrusion 16 and the positioning ring 13, and the positioning sleeve 3 and the support frame 4 can be connected as a whole, and the support frame 4 can be disassembled and assembled with the bottle body 1 along with the positioning sleeve 3.

[0029] In this embodiment, the reset elastic element 10 is a tapered cylindrical elastic sleeve. One side of the cylindrical elastic sleeve abuts against the abutting surface on the discharge sleeve 8, and the other side of the cylindrical elastic sleeve abuts against the positioning sleeve 3.

[0030] In this embodiment, a positioning protrusion 16 is provided on the inner wall of the positioning sleeve 3, and an annular positioning groove 19 is provided on the cylindrical elastic sleeve. The positioning protrusion 16 is inserted into the annular positioning groove 19. This structure further improves the positioning stability of the reset elastic element 10.

[0031] In this embodiment, the discharge sleeve 8 is rotatably fitted onto the sealing head 5. The inner wall of the positioning sleeve 3 is provided with four limiting ribs 20 evenly distributed around the center, and the discharge sleeve 8 is provided with four clearance openings 21 that correspond one-to-one with the four limiting ribs 20. With this structure, when not in use, the limiting ribs 20 and clearance openings 21 can be misaligned by rotating the discharge sleeve 8, thus preventing accidental pressure on the discharge sleeve 8 and opening of the discharge gap 7.

[0032] In this embodiment, the discharge sleeve 8 has a funnel-shaped relief opening 21. The top edge of the relief opening 21 cooperates with the limiting rib 20 to limit the movement distance of the discharge sleeve 8. Each time the limiting rib 20 is pressed to contact the relief opening 21, a single almost quantitative discharge effect can be achieved.

[0033] In this embodiment, the discharge sleeve 8 is provided with a positioning rib 22. When one side of the limiting rib 20 abuts against the positioning rib 22, the limiting rib 20 is aligned with the clearance opening 21. This structure allows for easy alignment of the positioning rib 22 and the clearance opening 21 by rotating the discharge sleeve 8 to abut against the positioning rib 22.

[0034] To further improve the effect of preventing accidental pressing, a blocking rib 23 is also provided on the outer periphery of the discharge sleeve 8. When the limiting rib 20 is misaligned with the clearance opening 21, the bottom of the blocking rib 23 blocks the limiting rib 20, so that the discharge sleeve 8 cannot be pressed down.

[0035] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
