Description

Lipstick tube

Technical Field

The invention belongs to the technical field of cosmetic packaging, and particularly relates to a lipstick tube.

Background

The traditional lipstick tube controls smooth rotation by rotating a spiral and utilizing a gap between the spiral and a fork, so that a barrel moves upwards along a guide groove on the inner wall of the spiral until lipstick is pushed out of a port of the fork. In order to ensure that the lipstick tube rotates smoothly integrally, oil is usually smeared on the spiral, but because a gap exists between the spiral and the fork, the oil is easy to seep out of the gap after smearing, the surface of a product is polluted, and the phenomenon of movement can occur; however, when the two are tightly screwed without clearance, squeaking sound occurs again, which affects the use of users.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further clarified by combining the specific drawings.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not denote a unique embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 and 2, the present invention provides a lipstick tube, which comprises a casing 10, a base 20 and a lipstick cover 30, wherein the base 20 further comprises: the gear-driven spiral gear comprises a spiral 11, a connecting piece 12 and a fork 13, wherein a concave part is further arranged above the middle of the spiral 11 in the vertical direction, a first sliding groove 111 is further arranged on a gear of the spiral 11, the connecting piece 12 is wrapped on the outer side of the spiral 11, a second sliding groove 121 is arranged at a position of the connecting piece 12 corresponding to the gear of the spiral 11, and the fork 13 is inserted into the concave part of the spiral 11; a plurality of balls 122 are further arranged between the first sliding groove 111 and the second sliding groove 121, a bottom groove 131 is further arranged at one end of the fork 13 far away from the spiral 11, and a plurality of arc-shaped protrusions 132 are further arranged on the inner wall of the bottom groove 131.

In the prior art, the conventional lipstick tube is formed by rotating the spiral 11, and the gap between the spiral 11 and the fork 13 is used to control smooth rotation, so that the barrel moves upwards along the guide groove on the inner wall of the spiral 11 until lipstick is pushed out of the port of the fork 13. In order to ensure that the lipstick tube integrally rotates smoothly, oil is usually smeared on the spiral 11, but because a gap exists between the spiral 11 and the fork 13, the smeared oil is easy to seep out of the gap, so that the surface of a product is polluted, and the phenomenon of movement is also generated; however, when the two are tightly screwed without clearance, squeaking sound occurs again, which affects the use of users.

According to the lipstick tube, the fork 13 and the spiral 11 are arranged separately, the fork 13 is inserted into the spiral 11, the situation that oil applied to the spiral 11 leaks onto lipstick carelessly is prevented, the ball 122 is additionally arranged between the connecting piece 12 and the spiral 11, the ball 122 is directly applied with oil by utilizing the principle of a bearing, the oil is prevented from being applied to the spiral 11, the retention rate is improved, the friction force is reduced, and the lipstick tube rotates more smoothly.

The technical scheme is that the base 20 is arranged in the shell 10, and the lipstick cover 30 is arranged above the shell 10 and is connected in a clamping manner; more preferably, one side of the lipstick cover 30 is fixedly connected with the casing 10, the casing 10 is provided with a convex part, the lipstick cover can be opened by pressing the convex part, so that the lipstick cover can be opened by one hand, the practicability is increased, and the structure diagram is not shown.

Further technical scheme does, ball 122 with first spout 111 and second spout 121 interference fit reduce the frictional force between connecting piece 12 and the spiral 11, and it is more reliable that interference fit can make ball 122 be difficult for dropping, and in addition, interference fit is more smooth and easy after ball 122 oil smearing.

A further technical scheme does, the bottom of fork 13 still is equipped with buckle 133 device, with the inner wall swing joint of spiral 11 depressed part, the effectual condition of rocking that prevents fork 13 in spiral 11 has increased stability, and simultaneously, swing joint can be after the lipstick is used up, takes out fork 13, changes new fork 13 of taking the lipstick, has practiced thrift the resource, and wherein, more preferably, buckle 133 device of fork 13 covers the material for soft, has effectively prevented that hard material from scraping spiral 11 inner wall, has also reduced the degree of difficulty that fork 13 took out.

Further technical scheme does, the top of connecting piece 12 still is equipped with horizontal piece 123, horizontal piece 123 closely cooperates with fork 13, and the effectual volatile gas after having isolated ball 122 the oil, simultaneously, the increase of horizontal piece 123 also makes base 20 more stable.

The base 20 further comprises a lipstick container 31 which is wrapped outside the fork 13, so that the capacity can be increased to the maximum extent, and meanwhile, the lipstick container 31 is placed outside, in the prior art, the lipstick use-up rate is low, because when the lipstick is used up, the lipstick in the bottom groove 131 cannot come out completely due to structural problems and is wasted, in the invention, the lipstick container 31 is placed on an extra side, and when the lipstick is used up, the lipstick can be taken down conveniently, so that the residual lipstick in the bottom groove 131 can be used, and the lipstick fee rate is reduced.

The further technical scheme is that the connecting piece 12, the spiral 11 and the ball 122 are of an integrated forming structure, the matching degree of the ball 122 with the first sliding groove 111 and the second sliding groove 121 can be improved through the integrated forming structure, and meanwhile, the production cost can be effectively reduced through the production mode of a production line.

The foregoing shows and describes the general principles, essential features, and inventive features of this invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
