The present invention relates to the technical field of lipstick tubes, in particular to an all-aluminum lipstick tube cartridge and a lipstick tube.
A finished product of a lipstick tube usually includes a cap, a cartridge and an outer base. The cartridge includes a sleeve portion, a spiral portion, an inner body portion and a cup portion sleeved in sequence from outside to inside. The cup portion is sleeved on the inner side of the inner body portion, and the cup portion is used for placing a lipstick paste body. The assembled cartridge is sleeved into the outer base of the lipstick tube and is then matched with the cap to assemble the finished product of the lipstick tube. Therefore, the cartridge becomes an important core part of the lipstick tube.
However, there are some problems on the lipstick tube cartridges in the existing market: it is not simple enough to assemble the cartridges in integral structure, and even the cartridges are assembled by using gum bodies. Moreover, when the existing cartridge is applied to the lipstick tube, the assembling fit degree among the sleeve portion, the inner body portion, the cup portion and the spiral portion of the cartridge is poor, and there is a problem that a twisting force is not stable enough. Meanwhile, accessories of the lipstick tube in the existing market are formed by various materials and are then assembled, so that great difficulty to recover and scrap the accessories is increased.
In order to solve a first technical problem of the present invention, the present invention aims to provide an all-aluminum lipstick tube cartridge.
In order to solve a second technical problem of the present invention, the present mention aims to provide a lipstick tube applying the all-aluminum lipstick tube cartridge.
The technical scheme adopted by the present invention to solve the first technical problem is as follows: an all-aluminum lipstick tube cartridge, including:
As an improvement, in the all-aluminum lipstick tube cartridge, the lower end of the sleeve portion and the lower end of the inner body portion are provided with the sliding connection structures matched with each other.
Further, in the all-aluminum lipstick tube cartridge, the lower end of the sleeve portion is formed with a turned edge turning toward the inner side of the first cavity, and the lower end of the inner body portion is formed with a convex ring portion in buckling fit with the turned edge.
As a further improvement, in the all-aluminum lipstick tube cartridge, the inner side wall located on the cup portion and formed on the fourth cavity is provided with at least one inclined diagonal rib, a head end of the diagonal rib is arranged on the inner side wall, and a tail end of the diagonal rib is located in the fourth cavity.
As an improvement, in the all-aluminum lipstick tube cartridge, the upper end of the inner body portion is formed with at least one groove opening slips into, and the groove opening is communicated with the guide slot in the same side.
Further, in the all-aluminum lipstick tube cartridge, an outer side wall of the lower end of the inner body portion is formed with several first rotation stopping ribs.
Yet further, in the all-aluminum lipstick tube cartridge, an inner side wall of the lower end of the inner body portion is formed with several second rotation stopping ribs.
As a further improvement, in the all-aluminum lipstick tube cartridge, the guide slots and the notches respectively communicated with the guide slots are integrally Z-shaped.
The technical scheme adopted by the present invention to solve the second technical problem is as follows: a lipstick tube applying the all-aluminum lipstick tube cartridge.
Compared with the prior art, the present invention has the advantages that
First of all, in the lipstick tube cartridge of the present invention, the convex pins are arranged on the cup portion, are enable to penetrate through the corresponding guide slots and are arranged in the spiral groove in the corresponding side, so that sliding connections between the cup portion and the inner body portion and between the cup portion and the spiral portion are realized respectively. The sleeve portion and the cup portion realize a sliding connection assembling effect between the sleeve portion and the cup portion by buckling fit between the turned edge and the convex ring portion, thereby, it is ensured that the sleeve portion, the spiral portion, the inner body portion and the cup portion sleeved together achieve effective and stable sliding connections and gum-free assembly is achieved, and furthermore, the twisting force stability thereamong is further enhanced.
Second, in the lipstick tube cartridge of the present invention, the sleeve portion, the spiral portion, the inner body portion and the cup portion all are aluminum parts. That is, the entire cartridge is made from an all-aluminum material. In such a manner, the all-aluminum cartridge not only is more environmental-friendly than a conventional cartridge made from a plastic material, but also further meets a development direction of “de-plasticizing” in the future.
Further description of the present invention in detail will be made below in combination with drawings and embodiments.
The embodiment provides an all-aluminum lipstick tube cartridge. Specifically, referring to
Specifically, referring to
In order to stretch the two convex pins of the cup portion into the guide slots of the inner body portion to meet an assembling requirement between the cup portion and the inner body portion, referring to
In order to stop rotation when the cartridge and other structures for assembling the lipstick tube are assembled in a gum-free manner, referring to
In order to improve a grasping force of the cup portion to the lipstick paste so as to meet pouring requirements of different users on pastes with different hardness, referring to
The embodiment further provides a lipstick tube. Specifically, the lipstick tube of the embodiment applies the all-aluminum lipstick tube cartridge.
In the lipstick tube cartridge of the embodiment, the convex pins are arranged on the cup portion, are enable to penetrate through the corresponding guide slots and are arranged in the spiral groove in the corresponding side, so that sliding connections between the cup portion and the inner body portion and between the cup portion and the spiral portion are realized respectively. The sleeve portion and the cup portion realize a sliding connection assembling effect between the sleeve portion and the cup portion by buckling fit between the turned edge and the convex ring portion, thereby, it is ensured that the sleeve portion, the spiral portion, the inner body portion and the cup portion sleeved together achieve effective and stable sliding connections and gum-free assembly is achieved, and furthermore, the twisting force stability thereamong is further enhanced.
Although the preferred embodiments of the present invention are described in detail above, it is to be understood clearly that for those skilled in the art, various alternations and changes can be made on the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be regarded as within the protection scope of the present invention.
