Description

Technical Field

[0001] The invention relates to the technical field of cosmetic packaging equipment, in particular to a replaceable columnar can. Background Art

[0002] Makeup can modify the face and improve the overall complexion. Therefore, today's women, whether in the workplace, in life or attending some more formal occasions, will appropriately put on some light makeup to improve their complexion. Since cosmetics cannot be in contact with the external environment for a long time, people have designed various packaging containers to hold cosmetics. Facial creams, facial masks, etc. are usually contained in a can body, in which a semicircular cavity is opened, and the cosmetics are placed in the cavity, and the cavity is sealed by a cover. The packaging can is a very important display body to attract consumers. Many consumers will use the quality of the packaging can as a factor to judge the quality of cosmetics and skin care products. Designing various visually impactful cosmetic packaging can structures is one of the important factors to attract consumers' attention.

[0003] However, most of the cosmetic packaging jars on the market have relatively simple functions and do not have the function of self-replacement and adjustment of appearance. The lids of the packaging jars are all fixed round lids or square lids, and the issue of which type of appearance consumers prefer is not considered; moreover, the inner liner of the packaging jar is not easy to replace, which will cause the jar to be discarded after use, resulting in a certain amount of resource waste.

[0004] In view of the above problems, in order to improve the flexibility of the product, reduce the waste of resources and improve its utilization efficiency, the present invention proposes a replaceable columnar tank. Summary of the invention

[0005] The purpose of the present invention is to provide a replaceable columnar tank, which has the advantages of strong flexibility, high utilization efficiency and environmental protection and resource saving, and solves the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a replaceable columnar can, comprising a bottle body component and a bottle cap component, wherein the bottle body component comprises a hand-pull gasket, an inner bottle, an inner liner, a spring cover, a middle bottle, a spring and an outer bottle, the hand-pull gasket is arranged at the upper end of the inner liner, the inner liner is buckled and connected to the inner cavity of the inner bottle, the buckle of the inner bottle is buckled and connected to the groove 2 of the middle bottle, the spring cover contacts the upper end of the spring and plays a guiding role, the spring is embedded in the annular groove of the middle bottle, and the bottle body of the middle bottle is buckled and connected to the groove 1 of the outer bottle through the bayonet; the bottle cap component comprises an outer cover, a tightening sheet and an inner cover, and the outer cover is buckled and connected to the outer wall of the inner cover.

[0007] Furthermore, a buckling protrusion is provided on the lower bottom of the inner cover, and a groove three is provided on the inner wall of the lower end of the outer cover, and the groove three is buckledly connected with the buckling protrusion.

[0008] Furthermore, a support surface is provided above the inner ring of the inner cover, and a tightening sheet is provided below the support surface. The tightening sheet can be used for sealing the bottle cap component and the bottle body component.

[0009] Furthermore, the hand-pull gasket is arranged at the upper end of the inner wall of the inner container, and the hand-pull gasket and the top of the inner container cooperate with each other and seal.

[0010] Furthermore, the diameter of the hand-pull gasket is larger than the inner diameter of the inner container.

[0011] Furthermore, the upper outer wall of the inner liner is provided with an external thread, the inner wall of the inner cover is provided with an internal thread, the internal thread of the inner cover and the external thread of the outer wall of the inner liner are threadedly connected, and a stop point is provided in the inner liner thread, so as to facilitate the positioning of the inner cover and the middle bottle.

[0012] Furthermore, the spring is embedded in the annular groove of the middle bottle.

[0013] Furthermore, the inner cavity of the inner bottle is provided with a guide groove and a vertical inner bottle guide groove, and a protrusion is provided at a position corresponding to the guide groove on the outer wall of the inner liner. The inner liner is rotated and inserted into the inner cavity of the inner bottle, and the protrusion slides along the guide groove and stops rotating after hitting the side of the guide groove vertical to the inner bottle, and enters the vertical inner bottle guide groove under the action of the spring, stops moving after hitting the upper limit, and the inner liner is fixed.

[0014] Furthermore, the outer cover, inner cover, spring cover, inner bottle, middle bottle and outer bottle may be in the shape of a square, a polygon, or a column (cylindrical or elliptical). Furthermore, the spring may be other elastic members.

[0015] Furthermore, when the inner liner is to be replaced, first press the original inner liner so that the lower edge of the protrusion of the inner liner hits the lower edge of the guide groove of the vertical inner bottle, then rotate the inner liner so that the protrusion of the inner liner enters the guide groove and slides out of the inner bottle along the guide groove, and take out the original inner liner; after taking out the original inner liner, put the new inner liner into the inner bottle, rotate the new inner liner so that the protrusion of the new inner liner slides into the guide groove, continue to rotate the new inner liner until the side edge of the protrusion of the new inner liner hits the side edge of the guide groove of the vertical inner bottle and stops, and the new inner liner then enters the vertical inner bottle guide groove under the action of the spring and stops after hitting the upper edge of the limit; the installation of the new inner liner is completed.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The invention provides a replaceable columnar can, which is connected with the outer cover and the inner cover by buckling positions, and the bottle cover component is spirally connected with the bottle body component. The outer cover can be replaced by an elliptical cover with a round cover, which solves the purpose of being selectable and replaceable when there is a problem with the bottle cover or the user does not like it in the traditional sense. A circle of annular grooves is provided on the outer side of the bottle body component, and a luminous strip is embedded in the annular groove, so that the user can quickly find the packaging can when he wants to use it, thereby improving the use efficiency of the product. By arranging the spring cover and the spring, the inner liner can be pressed downward, and when it touches the limit surface, it can be screwed out clockwise or counterclockwise to take the inner liner out of the middle bottle. When replacing, a new inner liner is put into the middle bottle, and the inner liner is pressed downward. The inner liner will rotate clockwise or counterclockwise during the downward process and stop when it touches the buckle. The inner liner will then enter the vertical guide groove under the action of the spring and stop after touching the limit, and the installation is completed. The traditional waste and pollution caused by discarding the packaging can after the material in the bottle is used up is solved, thereby achieving the purpose of both environmental protection and money saving.
