Technical Field

[0001] This utility model belongs to the field of daily necessities technology, and specifically refers to a press-type packaging bottle. Background Technology

[0002] In cosmetics, skincare products, and daily chemical products, small-volume liquid products such as serums, essential oils, and perfumes are often packaged in narrow-mouthed glass or plastic bottles. These containers typically have several design flaws. For example, when users pour liquids by gravity, high-viscosity liquids like serums or lotions have poor flowability, easily leading to interruptions in the flow, resulting in product waste or contamination of the bottle opening; the simple bottle structure makes them susceptible to oxidation and deterioration due to light exposure, reducing the product's shelf life; furthermore, glass bottles have poor impact resistance and are easily broken upon drop. Utility Model Content

[0003] The purpose of this invention is to provide a press-type packaging bottle with a multi-layer structure that can effectively isolate the effects of light, provide good protection, and reduce liquid residue in the bottle through pressing.

[0005] A press-type packaging bottle includes a bottle cap and a bottle body connected by threads. The top of the bottle body has a liquid outlet. The top of the bottle body is formed with a threaded protrusion for threaded connection with the bottom of the bottle cap. A stepped portion is formed between the top of the bottle body and the bottom of the threaded protrusion. The side wall of the bottle body is formed with a corrugated wall. A bottle cover with a lower opening is fitted onto the bottle body. The top of the bottle cover has an abutment hole for the threaded protrusion to extend out. The lower edge of the abutment hole abuts against the upper end face of the stepped portion. A lower pressure cap abuts against the bottom of the bottle body. The upper end face of the lower pressure cap is provided with a mounting sleeve plate that is detachably connected to the bottom side wall of the bottle body. The mounting sleeve plate extends between the bottle body and the bottle cover.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 — Figure 3 :

[0028] A press-type packaging bottle includes a bottle cap 1 and a bottle body 2 connected by threads. The top of the bottle body 2 has a liquid outlet 20. The top of the bottle body 2 is formed with a threaded protrusion 21 for threaded connection with the bottom of the bottle cap 1. A stepped portion 22 is formed between the top of the bottle body 2 and the bottom of the threaded protrusion 21. The side wall of the bottle body 2 is formed with a corrugated wall 23. A bottle cover 3 with a lower opening is fitted onto the bottle body 2. The top of the bottle cover 3 has an abutment hole 30 for the threaded protrusion 21 to extend out. The lower edge of the abutment hole 30 abuts against the upper end face of the stepped portion 22. The bottom of the bottle body 2 abuts against a lower pressure cap 4. The upper end face of the lower pressure cap 4 is provided with an installation sleeve 40 that is detachably connected to the bottom side wall of the bottle body 2. The installation sleeve 40 extends between the bottle body 2 and the bottle cover 3.

[0029] During implementation, the bottle body is installed by first fitting the bottle cover onto the outer surface of the bottle body, and then extending the threaded protrusion 21 out of the abutment hole 30 of the bottle cover 3 for abutment. A pressure cap 4 is then placed from the bottom of the bottle body 2, with the mounting plate 40 fitted onto the bottom of the bottle body 2. This completely protects the bottle body from sunlight and effectively enhances its protective effect.

[0030] During use, the user can operate it with one hand. By pressing down the cap, the corrugated wall can deform to a certain extent, thereby changing the pressure inside the bottle, which makes it easy to squeeze out high-viscosity liquid from the bottle.

[0031] It is worth mentioning that the mounting sleeve 40 can take the form of several plates or an integrated ring-shaped wrapping structure, both of which can achieve the fixation of the bottom of the bottle. Furthermore, the lower pressure cap and the mounting sleeve are integrally injection molded, thereby improving the overall structural strength.

[0032] Preferably, the side wall of the bottle body 2 is formed with a first limiting protrusion 24, and the first limiting protrusion 24 is located below the corrugated wall 23. The inner side wall of the mounting sleeve 40 is formed with a second limiting protrusion 41. When the mounting sleeve 40 is sleeved and installed at the bottom of the bottle body 2, the side wall of the first limiting protrusion 24 and the side wall of the second limiting protrusion 41 abut against each other vertically, and the bottom of the bottle body 2 abuts against the upper end face of the lower pressure cap 4.

[0033] In the above structure, the cooperating first limiting protrusion 24 and second limiting protrusion 41 can prevent the lower cover from rotating on the side wall of the bottle when pressed, and also effectively prevent the lower cover from falling off the bottom of the bottle.

[0034] Another solution to the rotation problem is to design the bottle body with a rectangular cross-section, which also achieves the effect of preventing rotation.

[0035] Preferably, the bottom of the bottle body 2 is formed with a raised protrusion 25. The raised protrusion can increase the distance between the bottom of the bottle body and the lower cap, reserve deformation space for bottle shrinkage, ensure that high-viscosity liquids are completely squeezed out, and reduce the residue rate.

[0036] Preferably, the bottom of the bottle body 2 extends beyond the lower opening of the bottle cover 3, and the outer edge of the lower pressure cap 4 extends outward to form a limiting ring 42. When the lower pressure cap 4 is pressed, the upper end face of the limiting ring 42 abuts against the bottom of the bottle cover 3. The main function of the limiting ring 42 is to limit the maximum pressing stroke of the lower pressure cap and prevent excessive squeezing from causing the bottle body to break.

[0037] Preferably, the side wall of the bottle body 2 is provided with a third limiting protrusion 26 located above the corrugated wall 23, and the inner side wall of the bottle cover 3 is provided with a limiting bracket 31. When the bottle cover 3 is fitted onto the bottle body 2, the limiting bracket 31 and the third limiting protrusion 26 engage in a limiting cooperation, facilitating fixation.

[0038] Preferably, the bottle cap 1 includes a cap body 10 and a cover 11. The cap body 10 is fixed inside the cover 11 by a snap-fit ​​method, and the inner wall of the cap body 10 is formed with an internal thread 12 that matches the threaded protrusion 21.

[0039] The bottle cap 1 adopts a split installation method, which can simplify the assembly process and reduce production costs.

[0040] Preferably, the outlet 20 is provided with an outlet core 5, and the outlet core 5 has a through hole 50 that communicates with the bottle body 2. The top of the cover body 10 is provided with a plug 13 that seals the top of the through hole 50.

[0041] The independent design of the liquid outlet core 5 in the above structure enables the control of liquid flow rate, achieving precise liquid dispensing at a small flow rate. Combined with the plug 13 inside the cover 10, it can further enhance the sealing effect and prevent air from entering.

[0042] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
