The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
In this application, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a system, article, or apparatus that comprises a list of elements is not necessarily limited to those elements expressly listed but may include other elements not expressly listed or inherent to such article or apparatus.
Referring to fig. 1 to 4, an embodiment of the present application provides a packaging tube which is convenient to assemble, and includes a storage element 100, a driving element 200, a guiding element 300, and a decoration element 400.
The storage element 100 comprises a barrel 110 for containing cosmetics (particularly lipstick, lipstick and other paste cosmetics) and a transmission rod 120 connected with the barrel 110, wherein the transmission rod 120 is of a hollow structure communicated with the bottom end of the barrel 110, the barrel and the transmission rod are integrally formed, and the bottom of the transmission rod 120 is provided with external threads; the driving element 200 has a tubular structure, and the inner wall is provided with a spiral groove 210 which is matched with the transmission rod 120 for driving the storage element 100; the guiding element 300 is rotatably matched with the driving element 200, and is provided with a limiting hole 310 for the transmission rod 120 to pass through and limiting the rotation of the storage element 100, when the transmission rod 120 penetrates into the limiting hole 310, the storage element 100 can slide along the axial direction of the guiding element 300 when the guiding element 300 rotates relative to the driving element 200, and naturally, in order to limit the rotation of the storage element 100, the transmission rod 120 is approximately flat, and the shape of the limiting hole 310 is matched with the cross section of the transmission rod 120.
Considering the problem that the storage element 100 is not detached from the limiting hole 310 when the guide element 300 is rotatably coupled with the driving element 200, the transmission rod 120 is provided with a protrusion 121 limiting the detachment thereof from the guide element 300. However, when the transmission rod 120 passes through the limiting hole 310, due to the existence of the protrusion 121, a large force is required to forcibly buckle the protrusion 121 into the guide element 300, so that the assembly is troublesome, and the protrusion 121 may be deformed during the buckling process, thereby affecting the limit position of the subsequent storage element 100.
In order to solve this problem, the end of the guiding element 300 is provided with open slots 320 extending from the limiting hole 310 to the edge thereof, the number of the open slots 320 is 2, and the open slots 320 are symmetrically arranged, when the transmission rod 120 is inserted into the limiting hole 310, the protrusions 121 are pressed against the inside of the limiting hole 310, and at this time, the open slots 320 are adaptively deformed outwards towards both sides, so that the protrusions 121 can smoothly enter the guiding element 300 (the protrusions 121 enter the rear open slots 320 to reset). Of course, to facilitate entry of the protrusion 121 into the guide member 300, the end of the protrusion 121 facing the guide member 300 also has a guide slope.
The conventional packaging tube is generally provided with the decoration member 400, the decoration member 400 is fixed to the guide member 300, but the end of the guide member 300 may have a gap with the inner wall of the decoration member 400, when the protrusion 121 of the storage member 100 moves to the vicinity of the open groove 320, the protrusion 121 may press the open groove 320, and the open groove 320 may expand toward the gap, resulting in a problem that the storage member 100 is easily separated from the guide member 300.
To solve this problem, the packaging tube convenient to assemble of the present application is provided with the protruding portion 330 which is used for limiting the opening of the limiting hole 310 against the inner wall of the decoration element 400 at the end portion of the guiding element 300, compared with the prior art, the present application makes the limiting hole 310 not easy to open, and avoids the problem that the storage element 100 is easy to separate from the guiding element 300.
Of course, in order to make the boss 330 abut against the inner wall of the decoration element 400, the boss 330 extends along the circumferential direction of the guide element 300, and the problem of fitting between the limit hole 310 and the boss 121 is avoided.
Further, since the decoration element 400 has a tubular structure, the protruding portion 330 has a circular arc shape with the same radial width in consideration of the uniform stress. The number of the protruding portions 330 is plural, and may be specifically set according to the requirement, in this embodiment, the number of the protruding portions 330 is 2, and the protruding portions 330 are symmetrically disposed, and the end faces of the guiding elements 300 are flush with each other.
Referring to fig. 1, there is a limiting mechanism between the guide member 300 and the ornamental member 400 that limits axial movement of both. In view of the environmental protection, the packaging tube of the present application adopts a limiting mechanism instead of the conventional glue connection, and specifically, the limiting mechanism includes an annular groove 340 provided on the guide member 300 and a convex ring 410 provided on the decoration member 400 and matched with the annular groove 340, and the convex ring 410 is formed by rolling. Of course, in the circumferential direction, the above boss 330 abuts against the inner wall of the decoration element 400, and the circumferential rotation therebetween can be restricted.
In this embodiment, the storage element 100, the driving element 200 and the guiding element 300 are hidden in the decoration element 400, so that the packaging tube needs to be matched with other components (avoiding separate use), for example, can be matched with the base 500.
Further, the packaging tube convenient to assemble further comprises a base 500, wherein an elastic claw 510 is arranged in the base 500, and the elastic claw 510 stretches into a gap between the guide element 300 and the driving element 200 and is matched with the annular protrusion 230 of the driving element 200 to realize axial limit. Wherein the number of the elastic claws 510 is specifically 4 and is uniformly distributed. Of course, in order to realize circumferential limitation between the base 500 and the driving element 200, the bottom end of the driving element 200 is provided with an axial limitation rib 220, and the limitation rib 220 is clamped with the inner wall of the base 500 to realize circumferential limitation of the two.
In view of the problem of improving the feel, the outer periphery of the driving element 200 is further provided with a spring 420, and the spring 420 and the guiding element 300 rub to provide torsion during rotation relative to the guiding element 300.
Referring to fig. 1-2, the top of the decoration element 400 is generally configured with a bevel, and when the base 500 is non-circular, for example, the cross section of the base 500 is generally rectangular in this embodiment, and the storage element 100 moves axially to the bottom end or top end of the guiding element 300, the bevel of the conventional decoration element 400 deviates from the base 500 by a larger angle (for example, aligns with the diagonal line of the rectangle), in order to solve this problem, the starting end of the bottom of the spiral groove 210 is close to the bottom of the driving element 200 (there is a certain gap between the two) so that the bevel aligns with just one side of the rectangular base 500 when the storage element 100 moves to the limit position of the bottom end of the spiral groove 210. Wherein the length of the memory element 100 that is capable of axial movement is an integer multiple of the helical lead.
The storage element 100, the driving element 200, the guiding element 300 and the decoration element 400 are assembled to form a middle beam core, specifically, the transmission rod 120 of the storage element 100 is firstly extended into the limit hole 310 of the guiding element 300, then the driving element 200 is installed between the guiding element 300 and the storage element 100 by using a jig, the assembly is then inserted into the decoration element 400, and finally the decoration element 400 and the guiding element 300 are axially limited by a rolling mode, so that the middle beam core assembly is completed.
The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description. When technical features of different embodiments are embodied in the same drawing, the drawing can be regarded as a combination of the embodiments concerned also being disclosed at the same time.
The above examples only represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the claims. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application.
