Description

Technical Field

[0001] The utility model relates to a cosmetic bottle, in particular to a square bottle, which utilizes a longitudinally extending column design to ensure tight fixation between a top cover and an inner cover, thereby preventing the two from being loosened. Background Art

[0002] There are many styles of cosmetic bottles, which generally have parts such as a top cover, an inner cover, an inner liner, and a base. The top cover and the inner cover are basically bonded together by bonding, and an internal thread structure is designed inside the inner cover. The internal thread is screwed to the external thread at the top opening of the base to achieve the coordination between the inner cover and the base, and the inner liner is placed in the internal cavity of the base.

[0003] Since the top cover and the inner cover of the above-mentioned cosmetic bottle are only bonded together, after repeated use, the top cover and the inner cover will loosen from each other in the lateral position and produce a fitting gap, thereby affecting the use of the product; at the same time, the inner cover and the base are only designed to fit together with a thread, and there is no corresponding positioning structure, which easily leads to problems of over-tightening or incomplete rotation. Utility Model Content

[0004] The purpose of the utility model is to provide a square bottle that uses a longitudinally extending column for positioning, and the technical problem to be solved is: optimizing the structure of the product, ensuring the tightness between the top cover and the inner cover to avoid looseness, and preventing the inner cover from rotating too tightly or too loosely on the base.

[0005] A square bottle positioned by a longitudinally extending column comprises a top cover, an inner cover and a base; the top cover is hollow inside and open at the bottom, and a longitudinal limiting portion is arranged at each of the four corners of the inner wall, and a longitudinal limiting groove is inside the limiting portion; a Y-shaped limiting column extending longitudinally upward is arranged at each of the corresponding four corners of the inner cover to form three side walls, two of the side walls of the limiting column are integrated with the middle circular body of the inner cover, and the third side wall is limited by the limiting groove; the bottom of the inner cover has a cover bottom, and the above-mentioned cover bottom has a 5-shaped snap-fit ​​portion extending downward, and the base has an outward-protruding snap-fitting protrusion at the corresponding position, and the above-mentioned snap-fitting protrusion is snap-fitted with the snap-fitting portion.

[0006] The square bottle has a square bottle body structure as a whole.

[0007] There is a gap above the buckle portion so that a local position of the buckle portion forms an elastic structure and cooperates with the buckle protrusion.

[0008] There are two buckle parts which are arranged opposite to each other.

[0009] The three side walls extend to the cover bottom and are integrated with the cover bottom.

[0010] The beneficial effects of the present invention are as follows: by designing the limiting portion and the limiting post, the limiting post can be firmly stuck in the limiting groove of the limiting portion, thereby avoiding the possible loosening problem between the top cover and the inner cover; by designing the buckle portion and the locking protrusion, the rotational positioning problem between the inner cover and the base is ensured, ensuring the accurate rotation position and avoiding over-tightening or over-loosening. The structural design of the middle round body, the bottom of the cover, and the limiting post of the inner cover ensures that it can be well fixed to the top cover and the base, reducing the overall height of the inner cover and simplifying the overall volume of the cosmetic bottle.

[0021] Please refer to Figures 1 to 6 The square bottle in the figure has a square body structure. The main optimization is the structure of the top cover 1, inner cover 2, and base 3, so that the three components are assembled more firmly and the overall volume of the square bottle is optimized. In actual application, the top cover 1, inner cover 2, and base 3 can be further optimized.

[0022] The top cover 1 in the figure is a square structure as a whole, which has four corners. The bottom of the top cover 1 has an opening and is hollow inside. At the same time, longitudinal limiting portions 11 structures are designed at the four corners of the inner wall. Each limiting portion 11 is hollow inside to form a limiting groove 111 structure. The height of the above-mentioned limiting groove 111 is close to the height of the entire top cover 1.

[0023] The inner cover 2 in the figure is designed with an integrally formed limiting column 21, an intermediate circular body 22, and a cover bottom 23. The limiting columns 21 are arranged at the four corners of the intermediate circular body 22 and aligned with the four limiting grooves 111 of the top cover 1, and the height of the limiting columns 21 is kept corresponding to the limiting grooves 111, so as to achieve a tight fit between the limiting columns 21 and the limiting grooves 111. The limiting columns 21 are Y-shaped as a whole to form a structure with three side walls and extending longitudinally upward, one of which is inserted into the limiting groove 111, and the other two side walls are an integral structure with the intermediate circular body 22, thus providing another assembly structure between the top cover 1 and the inner cover 2, thereby ensuring the tight fit between the top cover 1 and the inner cover 2 to prevent loosening. The intermediate circular body 22 is a hollow circular structure, and its inner side wall has an internal thread for easy screw connection with the base 3. The cover bottom 23 is located at the bottom of the entire inner cover 2, conveniently covering the corresponding position of the base 3. The limiting post 21 extends to the cover bottom 23 and forms an integral structure with the cover bottom 23, thereby enhancing the overall strength of the limiting post 21. To facilitate accurate rotation between the inner cover 2 and the base 3, a downward-extending, five-shaped snap-in portion 231 is designed at opposite positions on the bottom of the cover bottom 23. The base 3 is also designed with an outward-protruding snap-in protrusion 31 at a corresponding position. The snap-in protrusion 31 snaps into the inner groove 2311 of the snap-in portion 231, thereby achieving the snap-in assembly of the cover bottom 23 and the base 3. To facilitate the fit between the snap-in portion 231 and the snap-in protrusion 31, a gap 232 is designed above the snap-in portion 231. This allows a localized elastic structure to mate with the snap-in protrusion 31. In actual application, the number, shape, and structure of these components can be adjusted as needed.

[0024] The top of the base 3 in the figure has an opening and an external thread structure, wherein a laterally outwardly protruding latch 31 is designed at the position of the external thread. The base 3 has a cavity inside for placing the inner container.
