Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It will be understood that 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. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.

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 application belongs. The terminology used in the description of the present application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 to 6, the present application discloses a cosmetic package with a replaceable middle bundle core 1, comprising a middle bundle core 1 for mounting a paste body, a bottom case 2 and an upper cover 3 which are buckled with each other to accommodate the middle bundle core 1, at least two claws 21 extending towards the middle bundle core 1 are arranged in the bottom case 2, the bottom of each claw 21 is fixed with the bottom case 2, under the self deformation of each claw 21, the top of each claw 21 has a close-up position and a locking position which are far away from each other, the bottom of the middle bundle core 1 is provided with a positioning area 12 and a positioning shoulder 11 is arranged in the positioning area 12, and the top of each claw 21 extends to the positioning area 12 and is buckled with the positioning shoulder 11 under the locking position.

The top of each pawl 21 in the locked position corresponds to a detent ring that prevents movement of the core 1 relative to the base 2. When the top of each claw 21 enters the binding position, the circle diameter of the equivalent positioning ring formed by the top of each claw 21 is reduced, so that the middle binding core 1 can be released to move relative to the bottom shell 2.

In a specific matching relationship, in one embodiment, the relative movement path of the middle core 1 and the bottom shell 2 is a working path; the top of each claw 21 is provided with a positioning protrusion 211, the lower positioning protrusion 211 at the binding position avoids the positioning shoulder 11 on the working path, and the lower positioning protrusion 211 at the locking position blocks the positioning shoulder 11 on the working path.

Under the condition that the deformation stroke of the clamping jaws 21 is fixed, the positioning protrusions 211 enlarge the ring diameter of an equivalent positioning ring formed at the top of each clamping jaw 21, so that a better positioning effect can be provided. The positioning projection 211 has other functions in structure. In one embodiment, the positioning protrusion 211 has driving slopes 212 on both sides of the working path to cooperate with the core 1, and the driving slopes 212 are used to drive the tops of the respective jaws 21 into the binding position.

The positioning protrusion 211 needs to avoid the middle bundle core 1 on the working path during the assembly or separation of the middle bundle core 1 with the bottom case 2, so an effective structure is needed to drive the movement of the positioning protrusion 211. The drive ramp 212 is able to efficiently achieve this design requirement without adding components. The change of the slope of the driving slope 212, the surface roughness, and other parameters may be used to control the assembling torque or the separating torque of the middle bundle core 1 and the bottom case 2, and in the present embodiment, the separating torque of the middle bundle core 1 and the bottom case 2 is controlled to be about 3LBS through the setting of the driving slope 212.

The assembling moment or the separating moment of the middle bundle core 1 and the bottom case 2 is also influenced by the elastic force of the deformation of the claws 21, in addition to the different elastic coefficients of the materials of the claws 21 themselves, in an embodiment, the side surface of each claw 21 facing away from the middle bundle core 1 is provided with a reinforcing rib 213, the distance of the reinforcing rib 213 protruding out of the surface of each claw 21 is a reinforcing height, and the reinforcing rib 213 is derived from the bottom of the claw 21 to the top of the claw 21 and the reinforcing height gradually becomes smaller.

The contact area between the claw 21 and the bottom case 2 is small, and after multiple uses, stress concentration at the contact part between the claw 21 and the bottom case 2 may be caused, so that the claw 21 is broken, and the use of the product is affected. It is therefore desirable to distance the deformation of the jaws 21 as far as possible from the bottom of the jaws 21. The reinforcing ribs 213 in the present embodiment can effectively realize this function. At the bottom of jack catch 21, the enhancement height of strengthening rib 213 is great, can effectively realize the fixed of jack catch 21 and drain pan 2, and at the top of jack catch 21, the enhancement height of strengthening rib 213 is less, allows the abundant deformation of jack catch 21 in order to satisfy the needs under the different situations.

During the manufacture of the jaws 21, a mating of the dies is required. But the nature of the jaws 21 themselves to limit the working path can have an effect on mould release. In one embodiment, the bottom surface of the bottom shell 2 is provided with a mold release hole 214 of each claw 21, and in the radial direction of the bottom shell 2, the mold release hole 214 is arranged at the outer side of each claw 21 and the inner edge is flush with the bottom of each claw 21; the extension length of the knock out hole 214 is larger than the extension length of each claw 21 in the circumferential direction of the bottom case 2.

In the mold closing process, one part of the mold extends to the position near the positioning protrusion 211 from bottom to top through the mold opening 214, and the other part of the mold is closed with the mold from the top, so that after the production is completed, the existence of the mold opening 214 can ensure that the positioning protrusion 211 does not interfere with the movement path of the mold in the mold opening process, and the mold can be smoothly opened. The claw 21 can be produced integrally with the bottom shell 2, so that the overall strength of the claw 21 is improved, and production procedures are reduced.

From the perspective of the fit of the middle bundle core 1 and the jaws 21, in one embodiment, the bottom of the middle bundle core 1 is hollow to form a cylindrical structure, the inside of the cylindrical structure is the positioning area 12, the upper edge of the cylindrical structure is the positioning shoulder 11, and the top of each jaw 21 extends into the cylindrical structure.

The cylindrical structure can be formed by inwards turning over the material at the bottom of the middle bundle core 1, and the clamping jaw 21 can extend into the middle bundle core 1 to be matched with the positioning shoulder 11, so that the influence of a rotating part of the middle bundle core 1 on the positioning of the clamping jaw 21 is avoided. Besides the limiting function of the positioning shoulder 11 and the positioning protrusion 211, the claw 21 and the surface of the cylindrical structure also have the function of limiting the movement of the middle core bundle 1. As can be seen from the figure, the surfaces of the jaws 21 and the surfaces of the cylindrical structure abut against each other, thereby limiting the tendency of the core 1 to move relative to the surfaces of the jaws 21. The design can reduce the acting force on the joint part of the positioning protrusion 211 and the positioning shoulder 11 when the middle beam core 1 is stressed, ensure the coaxiality of the middle beam core 1 and the jaw 21 in the extending direction and further improve the tightness of the middle beam core 1 and the jaw 21. The positioning effect becomes more pronounced when the number of claws 21 is increased. In one embodiment, three claws 21 are provided and are uniformly arranged at the bottom of the bottom case 2 with equal diameter compared to the axis of the bottom case 2.

The jaws 21 are increased in number to provide limiting force from more directions, but under the condition that the size of a product is fixed, the size of a single jaw 21 is reduced due to the increase in number, the mold is complicated, and after multiple tests and selection of multiple working conditions, the number of the jaws 21 is preferably three.

Referring to fig. 5 and 6, the three claws 21 form a structure similar to a three-petal flower and can be matched with the bottom of the middle bunch core 1, the three-petal flower-shaped claws 21 hook the bottom of the middle bunch core 1, so that the middle bunch core 1 can be fixed in the bottom shell 2, and the three-petal flower buckling position structure formed by the claws 21 is demoulded by adopting a die inserting structure, and the structure is novel.

In an actual product, the form of the bottom case 2 may be changed. In one embodiment, the bottom case 2 includes the appearance case 22 and the structure case 23 nested with each other, the claws 21 and the mold release holes 214 are provided on the structure case 23, the outer circumferential surface of the structure case 23 is provided with a first rotation preventing block 231 protruding radially, and the first rotation preventing block 231 is fitted to the appearance case 22.

The structural shell 23 mainly plays a role of realizing the fixation and rotation prevention of the center core 1, and the appearance shell 22 mainly provides an externally good appearance. The two are produced separately, and different requirements can be met more specifically. In the related art, the appearance shell 22 and the structural shell 23 are generally glued, and after long-term use, gluing failure and the like may occur, so that the structural shell 23 rotates with the rotation of the central core 1. The core 1 can be replaced in time, and the external package cannot be used for a long time. This application has effectively guaranteed the long-term stable transmission of outward appearance shell 22 and structure shell 23 through first anti-rotation block 231. The above situation is avoided.

Accordingly, in one embodiment, a radially protruding second anti-rotation block 232 is provided on the inner circumferential surface of the structural shell 23, and the second anti-rotation block 232 is engaged with the core 1.

The second rotation prevention block 232 is engaged with the bottom ratchet of the middle bundle core 1 to restrict the rotation of the bottom of the middle bundle core 1 relative to the structural shell 23. The user realizes the rotation difference of the head and the bottom of the middle beam core 1 through the positioning and matching of the appearance shell 22, the first anti-rotation block 231, the structure shell 23, the second anti-rotation block 232 and the bottom of the middle beam core 1, and realizes the movement of the lipstick body.

Referring to fig. 6, the second anti-rotation blocks 232 are uniformly arranged in 4 on the inner circumferential surface of the structural shell 23, and a side facing the core 1 is provided with a chamfer to guide the assembly of the core 1 and the structural shell 23.

As will be apparent from the above description, the main component of the package in this application is the structural shell 23, and thus the cover 3 may also be in a mating relationship with the structural shell 23. In one embodiment, the structural shell 23 is provided with a buckling part 233 protruding compared with the appearance shell 22 on the side facing the upper cover 3, the buckling part 233 is provided with a positioning protrusion 234 protruding in the radial direction, and the upper cover 3 is provided with a corresponding structure matching with the positioning protrusion 234.

In this embodiment, the structure bottom and each component are mutually matched, and the skeleton function of the whole package is achieved. When all the parts are stressed, all the parts are transmitted to the structural bottom and matched with each other. The package wholeness is good, and the fit clearance is few, can also satisfy the requirement of changing well bundle core 1, can satisfy user's long-term user demand.

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.
