Background

In particular, the cosmetic product is exemplified by a lipstick, as shown in figure 1, the container sheath d is generally manually subjected to a rotary motion which is transmitted to a lipstick-containing cup which carries it axially inside the sleeve b, applying it by friction when it is moved into position. In fig. 1 the cup consists of a head portion a and a body portion c joined end to end. Since the cup moves inside the sleeve b, if the size difference between the cup and the sleeve b is small, the assembly stress of the two is large, which causes a large rotation resistance and is inconvenient for the user to use. To avoid this, the cup is usually smaller than the sleeve, but this arrangement tends to result in a loose fit, low rotational resistance, and the cup may wobble and be unstable when moving axially along the sleeve. Therefore, it is difficult to accurately dimension the sleeve and the cup to ensure that the fitting stress therebetween is of a suitable magnitude.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, belong to the scope of protection of the invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", "clockwise", and the like indicate orientations or positional relationships that refer to the orientation or positional relationship of a user when using the cosmetic container in a non-limiting manner.

In embodiments of the present invention, the cosmetic (not shown) refers to a lipstick applied by friction or alternatively a lipstick as a lip care. It is to be understood that the cosmetics in the embodiments of the present invention are not limited to lipstick or lip balm.

As shown in fig. 2 to 5, the embodiment of the present invention provides a mechanism of a cosmetic container, and the mechanism 100 includes a cup 130, a sleeve 110, and a damping member 140.

The cup 130 is for containing a cosmetic product, and the cup 130 is adapted to move within the sleeve 110 in cooperation with the guide 150 and the sheath 120 as described below. The movement includes up and down movement of the cup 130 relative to the sleeve 110.

The sleeve 110 is sleeved outside the cup 130. Generally, as shown in fig. 3, the casing 110 is a hollow member having both upper and lower ends open, and the cup 130 may be in contact with all or part of the inside of the casing 110 when the cosmetic is dispensed in the axial direction thereof, so as to ensure support of the cosmetic.

Further, the sleeve 110 is made of a metal material, which may be anodized aluminum. Due to the good thermal conductivity of the metal material, cooling of the cosmetic can be achieved more quickly when the cosmetic heat is injected by heat. As shown in fig. 2 and 4, the casing 110 is often exposed to the outside, and the casing 110 made of a metal material can also improve the appearance of the cosmetic, for example, exhibit a smoother appearance. Therefore, the sleeve 110 also has a certain decorative effect as an appearance member.

The damping member 140 can be elastically deformed. In some embodiments of the present invention, a damper 140 is disposed on the cup 130 between the cup 130 and the sleeve 110, the damper 140 contacting an inner wall of the sleeve 110 to create frictional resistance with the sleeve 110 as the cup 130 moves within the sleeve 110.

In other embodiments of the invention, the damping member 140 may be disposed on the sleeve 110, specifically, on the inner wall of the sleeve 110 and between the cup 130 and the sleeve 110, the damping member 140 contacting the outer wall of the cup 130 to generate frictional resistance with the cup 130 as the cup 130 moves within the sleeve 110.

The damping member 140 generates frictional resistance with the inner wall of the sleeve 110 or the outer wall of the cup 130, thereby preventing the cup 130 from shaking within the sleeve 110. The damping member 140 capable of elastically deforming also ensures smoothness and stability in the moving process of the cup 130, and also makes it easier for the user to perceive the amount of the cosmetics to be dispensed, and adjusts the cosmetics to a proper position more easily, thereby improving user experience. When the cup 130 is assembled with the sleeve 110, the damping member 140 can adjust the assembling stress between the cup 130 and the sleeve 110 through the elastic deformation of the damping member, so that the design difficulty of the size of the cup 130 and the size of the sleeve 110 is reduced.

Without limitation, as shown in fig. 3 to 12, the damping member 140 is a plate, and the damping member 140 may be made of an elastic material, such as metal or elastic rubber. The plate-shaped damper 140 is disposed to extend in the axial direction of the cup 130 and has a certain width radially outward from the outer wall of the cup 130. The sheet-like damper 140 is simple to manufacture and is more easily deformed. The damping member 140 may also take other shapes, such as cylindrical, conical, etc.

Optionally, the mechanism 100 includes at least two damping members 140, the at least two damping members 140 being evenly spaced along the circumference of the cup 130. The two or more damping members 140 are uniformly spaced along the circumference of the cup 130 to improve stability during movement of the cup 130. Fig. 3 to 12 show, by way of example, two damping elements 140 arranged symmetrically in the radial direction of the cup 130.

To further facilitate assembly of the sleeve 110 and the cup 130, in some embodiments of the invention, the damping member 140 has an inclined guide surface 1411, the guide surface 1411 configured to: the guide sleeve 110 is assembled with the cup 130.

When the damper 140 is disposed on the cup 130, as shown in fig. 3 to 5, and fig. 7, 8, and 9, the guide surface 1411 is located at the top 141 of the damper 140, and the guide surface 1411 is inclined from top to bottom in the axial direction of the cup 130 and outward in the radial direction of the cup 130.

When the damping member 140 is disposed on the sleeve 110, the guide surface 1411 may be located on the bottom 143 of the damping member 140, or both the top 141 and the bottom 143 of the damping member 140 may be provided with the guide surface 1411.

The inclined guide surface 1411 provides a guiding function when assembling the cup 130 and the sleeve 110, facilitating the mounting of the sleeve 110 with the cup 130 with the damping member 140.

Before the sleeve 110 and the cup 130 are assembled, the damper 140 may be bent in advance, and the edge 142 of the damper 140 may be bent in the following directions: in a tangential direction to the peripheral side of the cup 130.

Specifically, as shown in fig. 6, in some embodiments of the present invention, only the top portion 141 of the damping member 140 provided with the guide surface 1411 may be curved, and the top portion 141 of the damping member 140 may be curved in a tangential direction of the circumferential side of the cup 130. The bending deformation of the top 141 of the damper 140 can guide the deformation of the other parts of the damper 140 when the sleeve 110 and the cup 130 are assembled.

Further, when more than two damping members 140 are disposed on the cup 130, the bending deformation direction of the top 141 of each damping member 140 is the same, for example, both the bending deformation directions are clockwise, so that when the sleeve 110 and the cup 130 are installed, the damping members 140 are prevented from deforming in different directions, and the resistance applied to the peripheral side of the cup 130 is ensured to be uniform.

In other embodiments of the present invention, as shown in fig. 7 to 9, the damping member 140 is disposed on the cup 130, and all edges 142 of the damping member 140 away from the cup 130 may be pre-bent in a tangential direction to the peripheral side of the cup 130. This bending deformation can also prevent the damping members 140 from deforming in different directions, thereby ensuring that the circumferential sides of the cups 130 receive the same amount of resistance. It is understood that when the damping member 140 is disposed on the sleeve 110, the bent portion refers to: the damping member 140 is distal from the sleeve 110 and is adjacent to or in contact with the edge of the cup 130.

Alternatively, as shown in fig. 3, 4, 5, and 7-10, the top portion 141 of the damping member 140 has an inclined guide surface 1411, and the guide surface 1411 can serve as a guide during assembly of the sleeve 110 and the cup 130. Meanwhile, the edge 142 of the damping member 140 away from the cup 130 is bent and deformed in the tangential direction of the peripheral side of the cup 130, so that the damping members 140 are prevented from being deformed in different directions, and the peripheral sides of the cup 130 are ensured to be subjected to the same resistance.

The damping member 140 may not be bent in advance before the sleeve 110 and the damping member 140 are assembled.

In some embodiments of the invention, as shown in FIG. 11, the damping member 140 is not deformed before the cup 130 is assembled with the sleeve 110; as shown in FIG. 12, after the cup 130 is assembled with the sleeve 110, the damping member 140 is bent, and at this time, due to the restoring force of the bent damping member 140, the edge 142 of the damping member 140 away from the cup 130 presses the inner wall of the sleeve 110, thereby increasing the frictional resistance during the movement of the cup 130.

To be elastically deformed, generally, the sum of the inner diameter of the cup 130 plus the width of the damping member 140 in the same radial direction of the cup 130 is larger than the inner diameter of the sleeve 110. As shown in fig. 11 and 12, the sum of the inner diameter of the cup 130 and the width of the damper 140 in the same radial direction of the cup 130 is denoted as D1, the inner diameter of the sleeve 110 is denoted as D0, and D1 is greater than D0, so that the damper 140 deforms when the sleeve 110 is assembled with the cup 130.

Without limitation, cup 130 also includes an upper cup 131 and a lower cup 132, with cosmetic located in upper cup 131, with damping member 140 disposed on upper cup 131, and upper cup 131 disposed on top of lower cup 132.

As shown in fig. 3 and 4, the upper cup 131 and the lower cup 132 are in a split structure, and the upper cup 131 and the lower cup 132 are connected end to end. With further reference to fig. 6-10, the damper 140 and the cup 130 form a unitary member.

Further, the upper cup 131 and the lower cup 132 may also be a physically inseparable monolithic structure.

Optionally, cup 130 further includes ribs 1311, ribs 1311 being located on the inner wall of upper cup 131. As shown in fig. 3 to 5, and fig. 7 and 10, a plurality of ribs 1311 are provided circumferentially along the inner wall of the cup 130. The ribs 1311 may contact the cosmetic to better hold the cosmetic.

Without limitation, upper cup 131 includes a head 1312 and a tail 1313, head 1312 gradually increasing in diameter upward along the axial direction of sleeve 110; the tail portion 1313 is connected to the head portion 1312 and is disposed coaxially with the head portion 1312, and the diameter of the tail portion 1313 gradually increases downward in the axial direction of the sleeve 110 from the position where the tail portion 1312 is connected to the head portion 1312. Specifically, as shown in fig. 3, 4, 7 and 8, the upper cup 131 is a hollow member with two open ends, the head 1312 is in the shape of a horn with a large top and a small bottom, and the tail 1313 is in the shape of a horn with a small top and a large bottom. The flared head 1312 is disposed at the top of the casing 110 as close to the inner wall of the casing 110 as possible, and even contacts the inner wall of the casing 110, so as to seal the inner space of the casing 110 and prevent the entry of contaminants such as dust. The flared tail 1313 can provide a guide for the upper cup 131 and the lower cup 132 during assembly, thereby facilitating assembly of the upper cup 131 and the lower cup 132.

Movement of the cup 130 within the sleeve 110 may be accomplished by the guide 150 and the sheath 120. Specifically, the mechanism 100 further includes a guide 150 and a sheath 120, the guide 150 having a guide groove 153 axially disposed along the guide 150, the guide 150 being connected to the cannula 110; the sheath 120 comprises at least one spiral groove 121, and the sheath 120 is sleeved outside the guide 150; the cup 130 further comprises at least one lug 1321, the lug 1321 being arranged in particular on the lower cup 132, the lug 1321 being arranged through the guide slot 153 and cooperating with the helical slot 121 to move axially along the sleeve 110 when driven by the rotation of the jacket 120.

As shown in fig. 2 to 4, in this example, the dotted line portion in fig. 3 represents another position of the cup 130 and the damper 140 during the movement, and the dotted line portion in fig. 4 represents another position of the upper cup 131 and the damper 140 during the movement. The guide member 150 is provided with two guide grooves 153, the two guide grooves 153 are symmetrically arranged in the radial direction, the lower cup 132 is provided with two lugs 1321, and the lugs 1321 correspond to the guide grooves 153 one by one. Two helical grooves 121 are provided in the sheath 120, the lugs 1321 of the cup 130 passing radially through the axial guide slots 153 of the guide 150, so that each lug 1321 cooperates with one of the helical grooves 121 of the sheath 120. Thus, a rotational movement applied to the sheath 120 about the axial direction of the cup 130 can cause an axial movement of the cup 130 to move the cup 130 between the retracted position and the application position.

The sleeve 110 and guide 150 meet end-to-end. Without limitation, the bottom end of the sleeve 110 is provided with a notch 111, the notch 111 intersecting a circumferentially defined lower edge of the sleeve 110, the notch 111 being adapted to mate with a finger 154 described below to prevent circumferential movement of the sleeve 110 relative to the guide 150. In addition, the sleeve 110 and the guide 150 may be connected by gluing or crimping.

The guide 150 is a hollow member, the guide 150 includes a head 151 and a body 152 extending axially downward from the head 151, an upper flange 1521 is provided at an upper end of the body 152, a lower flange 1522 is provided at a lower end of the body 152, and the sheath 120 is sleeved outside the body 152 and limits axial movement of the sheath 120 relative to the guide 150 through the upper flange 1521 and the lower flange 1522. The head 151 of the guide 150 is provided with a finger 154 that matches the shape of the notch 111, and when the guide 150 and the sheath 120 are mated, the finger 154 can be received within the notch 111.

The embodiment of the present invention further provides a container, which includes a bottom shell (not shown), a top cover (not shown), and the mechanism 100 according to any of the above embodiments, wherein the bottom shell is sleeved outside the mechanism 100, specifically, the bottom shell is sleeved outside the sheath 120, and the top cover is detachably covered on the bottom shell.

Specifically, an external spline 122 is provided along the circumference of the cylindrical sidewall of the jacket 120, and an internal spline matching the external spline 122 is provided in the bottom case. The rotating bottom shell causes the rotation of the jacket 120, and therefore the lugs 1321 move inside the helical grooves 121, and the cup 130 dispenses the cosmetic product along its axial direction, in cooperation with the guide slots 153 of the guide 150. The damping member 140 can provide resistance for the rotation process, so that the stability of the cup 130 in the moving process is guaranteed, a user can conveniently adjust cosmetics to a proper position, and the user experience is improved.
