Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

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 an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements 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 utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

In the present disclosure, the terms "comprises" and "comprising," 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.

Along with the improvement of the moisturizing degree requirements of consumers, the existing paste cosmetics are oily, but the paste grabbing capability of the cylinder 11 in the traditional packaging tube is poor, so that the problem of easy falling exists.

In order to solve this problem, referring to fig. 1 to 7, an embodiment of the present utility model provides a packaging tube for preventing paste from falling off, which comprises a storage element 10, a driving element 20 and a guiding element 30.

The storage element 10 comprises a cylinder 11 for containing paste, wherein a plurality of first bulges 12 which extend along the circumferential direction and can be embedded into the paste are arranged on the inner wall of the cylinder 11; the driving element 20 is of tubular structure and the inner wall is provided with a helical groove 21 for driving the storage element 10; the guide member 30 is rotatably engaged with the drive member 20 to limit rotation of the storage member 10 when the drive member 20 rotates relative thereto.

The main reason that the paste easily drops is that the contact surface between the bulge inside the traditional cylinder 11 and the paste in the circumferential direction is less, so that the paste can slide and drop along the packing tube, and the utility model increases the contact area with the paste in the circumferential direction by arranging a plurality of first bulges 12 which extend along the circumferential direction and can be embedded into the paste on the inner wall of the cylinder 11, thereby improving the whole paste grabbing capacity of the cylinder 11 and avoiding the paste from dropping.

The window 13 has been seted up to the below of first protruding 12 for in the paste body ability embedding window 13 when filling paste, further promoted the ability of grabbing of barrel 11, in addition in order to be convenient for fill, first protruding 12 has the inclined plane 14 that guide the paste entering barrel 11.

In this embodiment, the first protrusions 12 are divided into multiple groups according to different heights, specifically, the first protrusions 12 are divided into two groups, namely, a first group 131 and a second group 132, wherein the first group 131 has a height greater than that of the second group 132, and are arranged at intervals. So that both sets can be embedded into the paste from different heights to provide better paste-grabbing ability. The specific number of the first protrusions 12 may be selected according to the requirement, and in the present utility model, the number of the first groups 131 and the second groups 132 is 2, and each group is symmetrically arranged. In addition, the inner wall of the cylinder 11 is provided with a plurality of second protrusions 15 extending in the axial direction, so that the paste can be prevented from rotating circumferentially.

The storage element 10 includes a link 17 extending into the driving element 20, the link 17 having a hollow structure communicating with the cylinder 11 and having a protrusion 19 mating with the spiral groove 21. The protrusion 19 is disposed at the bottom end of the linkage rod 17 and is matched with the spiral groove 21 through the guide element 30, specifically, the guide element 30 is provided with a guide groove 31 along the axial direction for the protrusion 19 of the linkage rod 17 to pass through, and when the driving element 20 rotates relative to the guide element 30, the storage element 10 is driven to slide along the guide groove 31 of the guide element 30. Of course, based on the structural features of the storage element 10 of the present utility model, the concrete filling mode of the paste is backward filling or hot filling.

The utility model further comprises a decorative element 40 fixedly connected to the guide element 30 concealing the cylinder 11. Wherein, the decoration element 40 is flush with the outer peripheral surface of the guide element 30, so that the whole modeling is more beautiful.

In this embodiment, the linkage 17 is detachably connected to the cylinder 11. For example, one of the two is provided with an annular protrusion 16, the other is provided with an annular groove 181 matched with the annular protrusion 16, in this embodiment, the annular protrusion 16 is arranged on the inner wall of the cylinder 11, the annular groove 181 is arranged on the outer peripheral wall of the linkage rod 17, and the two are matched to realize axial limit.

Similarly, in order to achieve circumferential limitation, one of the two is provided with a limiting groove 182, and the other is provided with a limiting key 32 matched with the limiting groove 182, in this embodiment, the limiting groove 182 is disposed on the inner wall of the cylinder 11, and the limiting key 32 is disposed on the outer peripheral wall of the linkage rod 17.

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 illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
