Description

Technical Field

[0001] The invention relates to the field of cosmetics, and in particular to a liquid cosmetic container. Background Art

[0002] Most of the existing deodorant structures are composed of a container bottle containing liquid deodorant, a rolling ball cavity and a liquid outlet hole are arranged on the top of the bottle, and an application head composed of a rolling ball is installed on the liquid outlet. When in use, the bottle is inverted, and the application head rolls to bring out the deodorant liquid and apply it on the body. The principle is similar to that of a ballpoint pen, and the whole is made of plastic parts. The liquid deodorant is discarded as a whole after use. When not in use, the bottle cap is tightened on the bottle body through threads, and the top ring in the bottle cap squeezes the rolling ball when the pre-tightening force of the threads is used, so that the rolling ball is fixed and blocks the liquid outlet hole, thereby avoiding leakage of the deodorant liquid.

[0003] The defect of the prior art is that, when a replaceable inner liner is used in the container in consideration of environmental protection factors, the original simple compression sealing method will lead to a significant decrease in reliability as the use time continues to extend; at the same time, since the replaceable inner liner will add a detachable press-fit connector, the connector is usually connected to the outer bottle body through a thread, and it is inconvenient to set a threaded structure on the bottle cap to connect with the outer bottle body. The bottle cap is mostly connected to the outer bottle body through a snap-fit ​​structure. At this time, the pressing force of the ejection ring on the rolling ball is also insufficient, further reducing the reliability of the seal when not in use; therefore, it will cause troubles to consumers, and therefore a new structure of the liquid outlet is needed, which is matched with a more reliable sealing form to enhance consumers' experience of using replaceable containers. SUMMARY OF THE INVENTION Technical issues

[0004] The technical problem to be solved by the present invention is to provide a roller ball type packaging bottle, which is additionally provided with a limiting ring that shrinks inward at the opening, and the limiting ring is pressed by a limiting piece on the bottle cap to improve the sealing reliability of the contact between the roller ball and the sealing surface in the non-use state.

Best Mode for Carrying Out the Invention

[0042] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally. Example

[0043] like Figure 2 , 3 As shown, a rolling ball packaging bottle comprises an outer bottle body 1, a bottle cap 2, a rolling ball 3, a connecting piece 4 and an inner bottle body 5, wherein the outer bottle body 1 and the inner bottle body 5 are containers with openings, the inner bottle body 5 is arranged in the outer bottle body 1, the connecting piece 4 is connected to the opening of the outer bottle body 1 and fixes the inner bottle body 5, the rolling ball 3 is arranged in the connecting piece 4, a limiting piece 6 is arranged on the inner ring of the bottle cap 2, the connecting piece 4 comprises a connecting seat 41 and a limiting ring 43, the limiting ring 4 3 is connected with the connecting seat 41 to form a rolling ball cavity 42, and the connecting piece 4 is installed on the outer bottle body 1 through the connecting seat 41. The limiting ring 43 is a cylinder coaxial with the connecting seat 41, and the inner cavity diameter of the cylinder matches the outer diameter of the rolling ball 3. The rolling ball 3 is arranged in the rolling ball cavity 42; when installing, the inner bottle body 5 is placed in the outer bottle body 1, and then the connecting piece 4 is installed. At this time, the connecting seat 41 of the connecting piece 4 presses and fixes the flange 51 of the inner bottle body 5 through the limiting surface 411;

[0044] The present invention can be further described as follows: a liquid outlet 44 connected to the inner bottle body 5 is provided on the connecting seat 41 on the side of the ball cavity 42 facing the outer bottle body 1, and a ring-shaped surface 45 that fits the outer surface of the ball 3 is provided on the upper edge of the liquid outlet hole 44; the opening of the limiting ring 43 on the side of the ball cavity 42 away from the outer bottle body 1 is contracted inwardly along the outer surface of the ball 3 by a certain distance so that the diameter of the opening of the limiting ring 43 is slightly smaller than the diameter of the ball 3, thereby keeping the ball 3 in the ball cavity 42; the limiting member 6 is a cylindrical body 61, and the cylindrical body 61 is installed in the bottle cap 2; under normal circumstances, the diameter of the opening of the limiting ring 43 gradually contracts inwardly to 80% to 95% of the diameter of the ball 3.

[0045] When not in use, the bottle cap 2 is mounted on the connector 4 and the cylindrical body 61 is interference fit with the outer wall of the limiting ring 43. The limiting ring 43 is made of a material with a certain elasticity, for example: when polyethylene PE material is used, the elastic modulus is 100-300 MPa, and when PP polypropylene material is used, the elastic modulus is 0.8-2.5 GPa. After the bottle cap 2 is covered, the interference fit causes the cylindrical body 61 to squeeze the limiting ring 43, so that the limiting ring 43 will shrink slightly inward, thereby causing the limiting ring 43 to lock the ball 3. At this time, at least one of the places between the ball 3 and the limiting ring 43, or between the ball 3 and the annular surface 45 is sealed. When in use, the bottle cap 2 is removed, and the roller-type packaging bottle is inverted. After the ball 3 contacts the surface of the human body and is subjected to pressure in the direction of the outer bottle body 1, it is in a loose state and can roll freely, so that the liquid cosmetics in the inner bottle body 5, such as deodorant, are brought out to the user's body surface by the rolling of the ball 3.

[0046] Taking environmental protection factors into consideration, the replaceable inner bottle body 3 in the present invention is made of a degradable material, and the degradable material is a paper material made of wood fiber, bamboo fiber, chitin fiber or polylactic acid fiber.

[0047] In Examples 1, 2, and 3, an ejector 21 is further provided on the inner wall of the bottle cap 2, and the ejector 21 is a cylindrical body, which is provided on the inner wall of the bottle cap 2; when not in use, the ejector portion of the ejector 21 directly or indirectly squeezes and fixes the ball 3 so that a sealing fit is formed between the ball 3 and the annular profile 45; when in use, the bottle cap 2 is removed, and the roller-type packaging bottle is inverted so that the ball 3 faces downward, at which time the ball 3 is in a loose state and can rotate freely, bringing out the deodorant liquid from the liquid outlet 44 and applying it to the consumer's body. Example 1

[0048] like Figure 1 , 2 As shown, the limiting member 6 and the bottle cap 2 are integrally formed into a whole. Example 2

[0049] like Figure 3 , 4 As shown, the cylindrical body 61 can be detachably mounted on the ejector 21; the difference between this embodiment and embodiment 1 is that the bottom of the area where the cylindrical body 61 cooperates with the outer wall of the limiting ring 43 extends horizontally outward and bends backward to form a supporting groove 63, and the outer wall of the supporting groove 63 fits with the inner wall of the bottle cap 2.

[0050] This embodiment can be further described as follows: an ejector plate 64 is provided on the side of the cylindrical body 61 away from the outer bottle body 1, and a first movable connecting groove 62 cooperating with the ejector 21 is provided on the top surface of the ejector plate 64; in a non-use state, the ejection portion of the ejector 21 indirectly squeezes and fixes the ball 3 through the bottom surface of the ejector plate 64; in view of the convenience of disassembly and assembly to facilitate cleaning, the first movable connecting groove 62 and the ejector 21 are connected by plug-in; in this embodiment, preferably, the ejector plate 64 is a flat plate. Example 3

[0051] like Figure 5 , 6 As shown, the difference between this embodiment and embodiment 1 is that a squeeze piece 7 is detachably installed in the bottle cap 2, the lower end surface of the squeeze piece 7 is a concave spherical surface 71 that matches the outer surface profile of the ball 3, and the upper end surface of the squeeze piece 7 is provided with a plug-in groove 73; when not in use, the ejection part of the ejection piece 21 indirectly squeezes and fixes the ball 3 through the concave spherical surface 71.

[0052] In this embodiment, in order to ensure the guiding property and extrusion stability during extrusion, the contact surface between the lower edge of the concave spherical surface 71 and the upper edge of the limiting ring 43 is a frustum surface 72, and the diameter of the frustum surface 72 away from the outer bottle body 1 is larger than the diameter of the side close to the outer bottle body 1.

[0053] In Examples 4, 5, and 6, an elastic supporting structure is provided on the connecting seat 41, and the limiting member 6 is a cylindrical body 61, which is installed in the bottle cap 2; when not in use, the elastic supporting structure pushes the ball 3 to be pressed against the limiting ring 43, at which time the cylindrical body 61 and the outer wall of the limiting ring 43 have an interference fit, so that the ball 3 is housed and a sealing fit is formed between the ball 3 and the limiting ring 43; when in use, the roller-type packaging bottle is inverted so that the ball 3 is downward, and during use, the ball 3 contacts the body surface and is pushed toward the bottle body 1 by pressure to push the elastic supporting structure, so that the ball 3 becomes loose and can rotate freely, and at this time the deodorant liquid flows onto the ball 3, and is brought out and applied to the consumer's body as the ball 3 rotates. Example 4

[0054] like Figure 7 , 8As shown in Figures 9 and 10, the elastic support structure is a plurality of elastic reset members 48 centrally and symmetrically arranged between the limiting ring 43 and the annular surface 45; the elastic reset member 48 is an S-shaped torsion spring or the material between the limiting ring 43 and the annular surface 45 is hollowed out to form an S-shaped elastic reset member 48.

[0055] In this embodiment, as a further improved embodiment, in order to facilitate the removal of the ball 3 for cleaning, the limit ring 43 includes a fixed ring 431 and a ball tube 432, and the fixed ring 431 is integrally formed and arranged on the connecting seat 41, and the bottom of the ball tube 432 is a second movable groove 433 that cooperates with the fixed ring 431, and the top opening of the ball tube 432 cooperates with the outer surface of the ball 3; usually, considering the connection reliability between the fixed ring 431 and the second movable groove 433, the two are connected by threads, and after removing the second movable groove 433, the ball cavity 42 can be opened and the ball 3 can be taken out.

[0056] When a split detachable structure is adopted, considering that the position of the cylindrical body 61 squeezing the limit ring 43 may be interfered by the second movable groove 433, the arc of the upper edge of the ball cylinder 432 is relatively large, so that the cylindrical body 61 can directly squeeze the upper part of the ball cylinder 432. Example 5

[0057] like Fig.11 , 12 As shown in Figures 13, the difference between Example 5 and Example 4 is that the elastic support structure includes a plurality of fan-shaped spring pieces 46, and the plurality of fan-shaped spring pieces 46 are arranged in a ring array in the inner circle of the liquid outlet 44, and a certain gap is left between two adjacent fan-shaped spring pieces 46; when not in use, the fan-shaped spring pieces 46 push the ball 3 to be pressed against the limiting ring 43; when in use, the ball 3 is pushed by pressure to open the fan-shaped spring pieces 46.

[0058] In this embodiment, as a further improved embodiment, a sealing ring 47 is provided on the upper edge of the limiting ring 43; when not in use, the sealing ring 47 is in sealing contact with the ball 3, and the sealing ring 47 is made of TPU material. Example 6

[0059] like Fig.14 , 15As shown in Figure 16, the elastic support structure includes a spring piece 491, a support piece 492 and a valve core 497. There is a certain travel gap 493 between the spring piece 491 and the support piece 492. A recessed area 494 is provided at the axis of the spring piece 491. The support piece 492 has a piston cavity 495 that matches the movement stroke of the recessed area 494. The recessed area 494 and the piston cavity 495 are provided with matching through holes 496. One end of the valve core 497 matches with the through hole 496 on the recessed area 494 through an open valve cover 498. The valve core The other end of 497 cooperates with the through hole 496 on the piston cavity 495 through the closed valve cover 499, and the open valve cover 498 makes the through hole 496 on the recessed area 494 in an open state in any state; when not in use, the spring 491 pushes the ball 3 to press against the limit ring 43, and at this time the closed valve cover 499 closes the through hole 496 on the piston cavity 495; when in use, the ball 3 is pushed by pressure to push the valve core 497 to move toward the bottle body 1, so that the recessed area 494 and the through hole 496 on the piston cavity 495 are both in an open state.
