Referring to fig. 1 to 3, the application discloses a cosmetic packaging container with a replaceable liner 2, which comprises a cover body 1, a liner 2 and a shell 3, wherein the cover body 1 and the shell 3 are buckled with each other to accommodate the liner 2, the upper edge 21 of the opening position of the liner 2 is outwards turned and overlapped on the shell 3, the outer side of the upper edge 21 is provided with at least one positioning part 22, the positioning part 22 extends downwards along the height direction of the liner and forms a positioning area 23 with the outer wall of the liner 2, and at least one part of the shell 3 is positioned in the positioning area 23;

the positioning portion 22 is provided with:

the anti-dropping part 221 is used for preventing the inner container 2 from moving relative to the shell 3 in the self axial direction;

a rotation prevention portion 222 for preventing the inner container 2 from moving in its own circumferential direction relative to the housing 3;

the part of the housing 3 located in the positioning area 23 is provided with a retaining block 33 for engaging the retaining portion 221 and an anti-rotation groove 34 for engaging the anti-rotation portion 222.

The inner bag 2 among the technical scheme that this embodiment is disclosed can select for use the environmental protection material, and inferior gram force material can be selected for use to casing 3 and lid 1, and the outer packing that casing 3 and lid 1 constitute can realize the inner bag 2 replacement many times, and outer packing can repetitious usage at this in-process, and this implementation can be when guaranteeing the grade of product and pleasing to the eye effectual excessive waste that reduces the extranal packing.

The above-mentioned alternative functions are realized by moving and fixing the liner 2 relative to the housing 3. The anti-falling part 221 and the anti-rotation part 222 in the embodiment meet the fixing requirement of the inner container 2 and the shell 3, and meanwhile, the anti-falling part 221 and the anti-rotation part 222 can be quickly and conveniently separated from the shell 3 when needed; thereby achieving the purpose of replacing the inner container 2.

More importantly, the positioning area 23 formed by the positioning portion 22 and the inner container 2 can shield relevant parts for accommodating and positioning, and prevent the structures such as the anti-falling portion 221 and the anti-rotation portion 222 from being exposed at the position that the user can contact, so that a better external appearance can be provided, the damage of the positioning structure to the user can be avoided, and the positioning stability can be ensured. Therefore, the replaceable design provided by the embodiment has small influence on daily use of the user, and can ensure use feeling while providing diversified use.

From the perspective of production, compared with the scheme in the related art, the scheme in this embodiment, which is realized by changing the matching form, has the advantages of simple structure and convenience in production and popularization. Taking a common manufacturing process in the field as an example, stable production can be realized only by adjusting a die, and the upgrading cost is low.

The inner container 2 provided in this embodiment is provided with two positioning portions 22, and the axes of the inner container 2 are symmetrically arranged on both sides of the upper edge 21 of the inner container 2.

Referring to fig. 4 to 7, in the details of the arrangement of the anti-falling portion 221 and the anti-rotation groove 34, in an embodiment, the housing 3 is provided with a threaded sleeve 31 matched with the cover 1, and the threaded sleeve 31 protrudes out of the upper surface of the housing 3 in the height direction of the liner; be equipped with on the thread bush 31 in location portion 22 complex location mouth 32, on the circumference of thread bush 31, the length of location mouth 32 is greater than the length of location portion 22, and location mouth 32 includes:

an escape section 321 that allows the positioning portion 22 to move downward in the inner-bag height direction and reach a first position;

the positioning section 322 is provided with an anti-falling block 33 and an anti-rotation groove 34, when the positioning portion 22 rotates from the first position to the second position (i.e. moves to the positioning section 322 along the circumferential direction of the threaded sleeve 31), the anti-falling portion 221 is engaged with the anti-falling block 33, and the anti-rotation portion 222 is engaged with the anti-rotation groove 34.

The positioning part 22 and the inner container 2 form a positioning area 23 with a U-shaped section, and the positioning area 23 is opened towards the threaded sleeve 31. When the inner container 2 is mounted in the housing 3, at least a part of the threaded sleeve 31 is located in the positioning region 23. In the present exemplary embodiment, the threaded sleeve 31 also has a positioning opening 32 for the positioning region 23. A part of the positioning opening 32 is a flat surface, so that the positioning opening 32 can enter and exit the positioning area 23, and after the avoiding section 321 of the positioning opening 32 enters the positioning area 23, the positioning portion 22 can move relative to the positioning opening 32 by rotating the liner 2, so that the positioning portion 22 located in the avoiding section 321 moves to the positioning section 322. The use requirements of the inner container 2 in different states can be better realized through the matching mode.

In the case of the matching problem of the details of the threaded sleeve 31 and the positioning opening 32, in one embodiment, the outer surface of the threaded sleeve 31 includes a base surface with the smallest diameter, and the positioning portion 22 in the state of being engaged with the positioning opening 32 is retracted inward in the radial direction of the threaded sleeve 31 compared to the base surface.

The threaded sleeve 31 is used to achieve fixation with the lid body 1, and therefore, it is necessary to avoid the influence of the positioning portion 22 and the positioning opening 32 on the threaded sleeve 31. In this embodiment, this problem is avoided by radial retraction.

In the cooperation between the positioning opening 32 and the positioning portion 22, the positioning portion 22 needs to enter the positioning opening 32 in the height direction of the liner, so the above-mentioned anti-falling block 33 and the anti-falling groove 34 cannot be provided in the avoiding section 321. It is understood that if the size of the anti-slip block 33 or the anti-slip groove 34 is too small, the positioning effect of the inner container 2 is not good. Therefore, in one embodiment, the ratio of the length of the positioning opening 32 to the length of the positioning portion 22 in the circumferential direction of the threaded sleeve 31 is greater than or equal to 2.

The parameter setting in this embodiment is to ensure that the positioning portion 22 and the positioning port 32 can satisfy both the need for separation and the stability during positioning.

In the specific arrangement of the retaining portion 221, in an embodiment, the retaining portion 221 is a first positioning convex strip protruding from the surface of the positioning portion 22, the extending direction of the retaining portion 221 is horizontal to the rotating direction of the inner container 2, i.e. the rotating direction of the inner container 2 is the same, and the retaining block 33 is a second positioning convex strip protruding from the surface of the positioning opening 32; the engagement state of the anti-slip part 221 is switched in the process of rotating with the inner container 2.

When the projections of the retaining portion 221 and the retaining block 33 overlap each other in the height direction of the liner, the liner 2 cannot be fixed by being separated from the casing 3. The structure is simple but the effect is stable.

In a specific configuration of the rotation preventing portion 222, in an embodiment, the rotation preventing portion 222 is a positioning convex strip protruding from the surface of the positioning portion 22, the extending direction of the anti-falling portion 221 is perpendicular to the rotating direction of the liner 2, the rotation preventing groove 34 is disposed on the anti-falling block 33, and the rotation preventing portion 222 and the rotation preventing groove 34 are aligned to limit the liner 2 to move in the circumferential direction relative to the housing 3.

After the rotation preventing portion 222 is aligned with the rotation preventing groove 34, the rotation preventing portion 222 falls into the rotation preventing groove 34, so that the inner container 2 is prevented from moving relative to the casing 3 in the circumferential direction, the mutual overlapping of the projections of the anti-falling portion 221 and the anti-falling block 33 is ensured, and the positioning effect of the inner container 2 is ensured.

The rotation preventing portion 222 does not have a simple limit function. Compared with the positioning structure in the related art, the anti-rotation portion 222 in this embodiment needs to realize the function of separating the inner container 2 in addition to the positioning function when the inner container 2 is installed, and therefore, in an embodiment, in the rotation direction of the inner container 2, two sides of the anti-rotation portion 222 are provided with arc surfaces for guiding the anti-rotation portion 222 to enter or exit the anti-rotation groove 34.

The cambered surface can establish a separation threshold, and when the force for driving the inner container 2 to rotate (including the conditions of acting force generated on the inner container 2 when a user uses cosmetics in the inner container 2 in daily life and the like) is lower than the separation threshold, the inner container 2 can ensure the positioning effectiveness; when a user needs to separate the inner container 2 from the shell 3, the inner container 2 is forcibly driven to rotate, the rotating force is greater than the separation threshold value, and the anti-rotation part 222 and the anti-falling block 33 can be smoothly separated.

The same applies to the attachment of the lid body 1 and the case body 3, similarly to the rotation preventing portion 222 and the escape prevention block 33. Therefore, referring to fig. 5 and 8, in an embodiment, the cover 1 is provided with a screw thread 121 engaged with the screw sleeve 31, an engaging groove 122 is provided near a starting position of the screw thread 121, and an engaging protrusion 35 engaged with the engaging groove 122 is provided near an ending position of the screw sleeve 31.

The starting position of the thread 121 and the ending position of the thread bush 31 are relative concepts, the starting position of the thread 121 and the ending position of the thread bush 31 are in contact with each other when the thread 121 and the thread bush 31 are rotated to the joint of the cover 1 and the case 3, and the engaging groove 122 and the engaging projection 35 are used for determining the ending point of the approach of the cover 1 and the case 3 to each other and maintaining the both in the ending state.

As described above, the operation of the engaging groove 122 and the engaging protrusion 35 is similar to that of the rotation preventing portion 222 and the anti-falling off block 33, and therefore, in one embodiment, the start of the thread 121 is provided with a guiding inclined surface for guiding the thread 121 to pass over the engaging protrusion 35 to realize the engagement between the engaging protrusion 35 and the engaging groove 122.

The engaging groove 122, the engaging protrusion 35, the anti-rotation portion 222 and the anti-separation block 33 have the functions of improving the user experience, in addition to the structural function. The user can obtain clear sense of touch change when the rotary component, form "paragraph feel", and when rotating to the predetermined position, the user can obviously perceive the change to build the high-grade feel of the product.

More importantly, the terminal-limiting forms of the engaging grooves 122 and the engaging protrusions 35 have significant advantages compared with the terminal-limiting forms of the threads 121 and the threaded sleeves 31. The limitation of the thread 121 and the thread sleeve 31 at the end point requires the user to rotate the housing 3 and the cover 1 to a state that the user cannot screw, so that the operation feeling is not good, and the over-rotation condition such as over-screwing can be caused along with the difference of the user strength level and the different performance of the material mechanics. In the case of a square packaging case in the drawing, the cover 1 and the case 3 may not be aligned, and in the case of other shapes, the case 3 or the cover 1 may be broken.

In the production of the cap body 1, it is obvious from the above that the inner cap 12 provided with the thread 121 requires high precision to ensure the feeling of use, and the outer cap 11 often requires good appearance, and the integral molding of both increases the manufacturing cost of the cap body 1. Therefore, in one embodiment, the cap body 1 includes an inner cap 12 provided with the screw thread 121 and an outer cap 11 covering the inner cap 12, and the outer circumferential surface of the inner cap 12 is provided with a projection bar 123 for fitting with the outer cap 11.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features. When technical features in different embodiments are represented in the same drawing, it can be seen that the drawing also discloses a combination of the embodiments concerned.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application.
