Description

Technical Field

[0001] The present application relates to the field of cosmetic packaging, and in particular to a packaging tube. Background Art

[0002] In order to cater to the aesthetic needs of consumers, the structures of existing lipstick packaging tubes are also varied. For example, the document with publication number CN203913825 U discloses a button-type lipstick packaging tube, which includes a cylindrical outer cover, a lipstick component slidably inserted in the outer cover, and a pressing cover that slidably cooperates with the inner wall of the outer cover to separate the lipstick component from the outer cover, and also includes a reset spring arranged in the outer cover to reset the pressing cover. The lipstick component includes a tube body and a middle bundle core whose bottom is fixed in the tube body. A limiter for constraining the axial position of the tube body is also provided in the outer cover, and an annular flange that cooperates with the limiter is provided on the outer wall of the bottom end of the tube body.

[0003] When in use, one only needs to press the push cover, and when the annular flange is separated from the limiting part, the lipstick part can be taken out for use. However, this type of annular flange is arranged on the outer wall of the bottom end, and the overall appearance of the lipstick part will be affected, which is not beautiful enough. On the other hand, the annular flange will produce material chips on the outer wall of the tube body due to the friction with the limiting part for a long time, which reduces the overall grade, so further improvement is needed.

[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] It should be noted that when a component is referred to as being "connected" to another component, it may be directly connected to the other component or there may be a central component. When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0042] In this application, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number or order of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0043] In this application, the terms "comprises" and "has" and any variations thereof are intended to cover non-exclusive inclusions, for example, a system, product or device comprising a series of units is not necessarily limited to those units explicitly listed, but may include other units not explicitly listed or inherent to these products or devices.

[0044] See also Figure 1 to Figure 6 , an embodiment of the present application provides a packaging tube, which has a carrying state and a use state, for example, see Figure 4-5 , for the carrying state of the packaging tube, see Figure 6 , which is the use state of the packaging tube, the packaging tube includes a tube assembly 100, a storage assembly 200, a cover element 300 and a pressing member 400.

[0045] The tube assembly 100 has a first end 101 and a second end 102. The storage assembly 200 is used to store cosmetics (specifically, lipstick, lip gloss and other paste-like cosmetics), and has an open end 201 and a closed end 202. In the carrying state, the storage assembly 200 is completely hidden inside the tube assembly 100.

[0046] The cover element 300 is used to be plugged into and cooperated with the storage assembly 200 to close the open end 201. The cover element 300 is slidably arranged inside the tube assembly 100, and a blocking structure is arranged between the cover element 300 and the tube assembly 100 to limit its movement toward the second end 102. The pressing piece 400 is movably arranged at the first end 101. In the use state, the pressing piece 400 acts on the cover element 300 to overcome the resistance of the blocking structure, thereby allowing the closed end 202 to extend from the second end 102.

[0047] In the packaging tube of the present application, a blocking structure is provided between the cover element 300 and the tube assembly 100 to limit the movement of the cover element 300 toward the second end 102. By pressing down the pressing member 400, the resistance of the blocking structure is overcome, so that the closed end 202 of the storage assembly 200 extends from the second end 102. Compared with the prior art, the overall shape of the storage assembly 200 of the present application is more beautiful, which improves the overall grade of the packaging tube.

[0048] In this embodiment, the packaging tube of the present application is a square packaging tube, and its cross section is specifically a square.

[0049] See also Figure 3-4 The tube assembly 100 includes a tube body 110 (which may be made of aluminum to improve the overall texture) and a hollow limiting element 120 fixed in the tube body 110. In order to facilitate fixation, a plurality of axially arranged ribs 124 are provided on the outer peripheral wall of the limiting element 120. 3M glue can be applied to the ribs 124 to fix the limiting element 120 to the tube body 110, wherein the blocking structure is provided between the cover element 300 and the limiting element 120.

[0050] Further, the blocking structure includes a first engaging portion and a second engaging portion which are respectively arranged in a radially displaced manner on the limiting element 120 and the cover element 300. Specifically, the inner wall of the limiting element 120 is provided with an annular groove 121 constituting the first engaging portion, and the outer wall of the cover element 300 is provided with a convex point 310 constituting the second engaging portion. In order to make the force more uniform, the number of the convex points 310 is multiple and evenly arranged along the circumferential direction. In this embodiment, the number is specifically 4.

[0051] In order to prevent the cover element 300 from being separated from the pipe assembly 100 in use, an anti-separation structure is provided between the cover element 300 and the limiting element 120. Figures 5 to 10The anti-slip structure includes a snap button 320 provided on one of them and a limiting step 122 provided on the other to cooperate with the snap button 320. Preferably, the snap button 320 is provided on the outer peripheral wall of the cover element 300, and the limiting step 122 is provided on the inner peripheral wall of the limiting element 120. In order to guide the cover element 300 to move along a predetermined route, the limiting element 120 is provided with a guide groove 123, one end of the guide groove 123 is open, and the other end is closed to form the limiting step 122. In order to cooperate with the guide groove 123, the snap button 320 protrudes radially relative to the cover element 300 and cooperates with the bottom surface of the guide groove 123. In this embodiment, the number of the snap buttons 320 is 4.

[0052] In order to prevent the storage component 200 from falling off the cover element 300, the cover element 300 of the present application is partially thinned and recessed inward to form a third locking portion 330 for locking the storage component 200. The locking friction between the third locking portion 330 and the storage component 200 is greater than the gravity of the storage component 200.

[0053] Of course, the packaging tube of the present application also includes an elastic element 500 arranged between the cover element 300 and the pressing piece 400. The elastic element 500 can be a spring. When in the carrying state, the elastic element 500 is in a compressed state. When it is needed, the pressing piece 400 is pressed, and the cover element 300 can overcome the resistance of the blocking structure and move along the guide groove 123 toward the second end 102. At this time, the elastic element 500 in the compressed state releases elastic potential energy, which can not only reset the pressing piece 400, but also continue to drive the cover element 300 to move toward the second end 102 until the spring buckle 320 is limited by the limiting step 122. Then, the bottom of the storage component 200 can be held, and force is applied downward to pull the storage component 200 out of the cover component 300 for use.

[0054] The resistance between the blocking structures is greater than the acting force of the spring in the carrying state, so as to prevent the storage assembly 200 from being automatically ejected.

[0055] In this embodiment, the axial distance between the pressing member 400 and the limiting member 120 is 3 mm, that is, the pressing member 400 can be pressed downward by 3 mm, and the distance that the cover member 300 can move toward the second end 102 under the action of the spring is 11 mm, that is, the distance that the storage assembly 200 can extend from the second end 102 is 11 mm, so that a relatively long storage assembly 200 can be ejected with a relatively small pressing force. Of course, the pressing and ejecting distance parameters can be adaptively adjusted according to needs.

[0056] See also Figure 2The storage assembly 200 includes a middle beam core 210 and a base 220, the base 220 is clearance-matched with the tube assembly 100, and the cover element 300 and the base 220 are combined to close the middle beam core 210. In this embodiment, the middle beam core 210 can adopt an existing structure, for example, including a storage element, a guide element and a driving element, wherein the inner wall of the driving element is provided with a spiral groove, and the top of the guiding element is provided with a limiting hole for limiting the circumferential movement of the storage element, and the storage element extends into the limiting hole and cooperates with the spiral groove, and when the driving element and the guiding element rotate relative to each other, the storage element can be driven to move axially.

[0057] For further information, see Figure 11-12 The base 220 includes an inner bottom 230 and an outer bottom 240 that are fixedly connected, wherein the four corners of the inner bottom 230 are designed to avoid air gaps to avoid the problem of surface shrinkage. To facilitate fixation, the outer surface of the inner bottom 230 may also be provided with axially arranged ribs 124, and glue is applied inside the ribs 124 to fix it to the inner wall of the outer bottom 240.

[0058] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0059] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
