Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description.

As shown in FIG. 1, this embodiment is a rotary two-component combination bottle for separately containing two different liquid cosmetics.

The rotary double-material combined bottle comprises a cylindrical bottle body 1, wherein the opening of the bottle body 1 is arranged above, and the bottle body is a screw opening in the embodiment and can be matched with a corresponding bottle cap or a pressure pump, a suction pipe and the like for use. The bottle body 1 is cylindrical, the lower end of the bottle body is provided with an opening, and a second container body 3 is embedded in the opening at the lower end of the bottle body 1 in a sealing way. The second chamber body 3 is a cylinder with a closed top surface and an open bottom surface, and a piston 4 is sleeved in the second chamber body 3 in a tight fit manner. The space above the second chamber body 3 is a first chamber 11, and the space surrounded by the second chamber body 3 and the piston 4 is a second chamber 12. The second container body 3 is provided with a material passing hole which penetrates through the first container 11 and the second container 12, and the material passing hole is plugged by a sealing plug 2 in an interference fit mode. The pushing piece 5 is fixedly connected below the piston 4, and the pushing piece 5 can push the piston 4 to slide upwards in the second cabin body 3. The rotating part 6 is sleeved on the outer side of the lower part of the side wall of the bottle body 1.

As shown in fig. 2 and 3, the material passing hole 31 designed on the second capsule body 3 of the present embodiment is circular and is matched with the circular material passing hole, and the sealing plug 2 is in a cone frustum shape with a large top and a small bottom. Specifically, referring to fig. 4, the large end of the truncated cone is located on the first tank 11 side, i.e., the upper side, and the small end is located on the second tank 12 side, i.e., the lower side. The end surface of the small end of the sealing plug 2 is provided with a mounting blind hole 21 in a concave manner, the corresponding position on the upper end surface of the piston 4 is provided with a piston guide pillar 41 in a convex manner, and the mounting blind hole 21 is in adaptive insertion connection with the upper end of the piston guide pillar 41. The side wall of the sealing plug 2 is provided with concave guiding grooves 22, in this example 3, which are arranged in the circumferential direction with an included angle of 120 °. The lower end of the diversion trench 22 in the length direction is an open end, the upper end is a closed end, the open end is opened at the small end of the sealing plug 2, and the closed end is close to the large end of the sealing plug 2.

The rotating piece 6 is coaxially sleeved outside the lower part of the bottle body 1. The rotation member 6 is freely rotatable by a key groove fitting structure, but is fixed in an axial position with the bottle body 1. The inner side wall of the rotating member 6 is spirally provided with a protruding pushing step 61. Referring to fig. 5, a pushing block 51 is convexly arranged on the outer side wall of the pushing member 5. The bottom of the pusher block 51 fits the top surface of the pusher step 61. In this example, a positioning groove 32 is provided below the outer side wall of the second cabin body 3, the positioning groove 32 extends vertically, and the upper end is closed. With continued reference to fig. 5, a positioning block 52 is disposed at a corresponding position on the inner sidewall of the pushing member 5, and the positioning block 52 is disposed in the positioning groove 32 and can slide up and down. Therefore, when the rotating member 6 rotates, the pushing member 5 is not displaced in the circumferential direction, but slides upward only by the force of the pushing step 61 pushing the pushing block 51. In this example, a small bump is designed at the tail part of the propelling step 61 near the upper part, and a platform is arranged behind the small bump, which is the terminal point of the propelling step 61. A particular feel is created when the pusher block 51 slides to the bump, indicating to the user that the end of rotation is about to be reached.

As shown in fig. 5, the upper end of the pusher 5 is provided with a piston mounting boss 53 projecting upward. Correspondingly, a piston mounting blind hole 42 is correspondingly arranged below the piston 4, and the piston mounting boss 53 is inserted in the piston mounting blind hole 42 in a matching manner. Because piston installation boss and piston installation blind hole are circular, consequently need design to prevent both relative circumferential direction's structure. In this example, the bottom of the piston 4 is provided with a piston reinforcing wall 43 arranged along the direction perpendicular to the sliding direction of the piston, and by virtue of this structure, the piston mounting boss 53 is provided with a circumferential limiting groove 54 in a concave manner, and the circumferential limiting groove 54 is inserted into one of the piston reinforcing walls 43. Meanwhile, the side wall of the piston mounting boss 53 and the hole wall of the piston mounting blind hole 42 are provided with a fitting pair for restricting the axial separation from each other. The matching pair of the embodiment is that a circle of anti-loosening convex rib 55 is convexly arranged on the side wall of the piston mounting boss 53, a circle of limiting concave ring is concavely arranged on the corresponding position on the hole wall of the piston mounting blind hole 42, and the two rings form a matching relationship.

In the case of the rotary two-material composite bottle, the first material can be filled in the first chamber 11 of the bottle body 1, and the second material can be filled in the second chamber 12 of the second chamber 3. Because the second container 12 and the first container 11 are fixed together, the chance that the second container 12 is touched by mistake when the buckling is finished after filling is obviously reduced, and the filling efficiency is higher. When the piston 4 is used for the first time, a consumer only needs to slightly rotate the rotating piece 6 to push the propelling piece 5 and drive the piston 4 to move upwards. The piston 4 firstly pushes open the sealing plug 2 to restore the conduction of the material passing hole 31, and then the second material in the second containing chamber 12 is extruded upwards from the material passing hole 31 to be mixed with the first material in the first containing chamber. This scheme is particularly suitable for the packing scheme that two kinds of materials are liquid.
