Description

A kind of exchangeable packing tube

Technical field

The utility model relates to exchangeable lipsticks or lip-stick package that a kind of packing tube more particularly to a kind of bottom fill cream Pipe.

Background technique

Lipstick packing tube is generally made of top cover, pedestal and middle beam core, wherein to be fixedly connected between pedestal and middle Shu Xin, Top cover and base engagement form the cavity of Shu Xin in encirclement.Existing single lipstick color is usually fixation, is disappeared to meet The person of expense replaces the needs of lipstick, and some lipstick packing tubes set replaceable for middle Shu Xin.

As CN205006228U discloses a kind of exchangeable lipstick packing tube, including tube body and activity are plugged on tube body The bottom of interior middle Shu Xin, the middle Shu Xin have the boot segment radially collapsed, are equipped between the circumferential surface and tube body of the boot segment Cooperate circumferential position limiting structure, but the lipstick packing tube structure of the patent disclosure is relative complex, and manufacturing cost is high.

For another example CN202722923U discloses a kind of exchangeable lipstick packing tube, including tube body and by middle beam, middle section, The middle Shu Xin of pearl and spiral composition, the tube body is interior to be equipped with magnetic patch, and the middle Shu Xin further includes that fixation is set in outside spiral Bushing, which protrudes into circumferentially fixed with tube body circle in tube body, the bushing and magnetic patch interaction.Because of the thickness of bushing Very little is such as arranged locating slot on it or positioning plate, difficulty of processing is higher.

Utility model content

The utility model provides the exchangeable packing tube that a kind of structure is simple, easy to assembly.

A kind of exchangeable packing tube, including tube body and middle Shu Xin, the middle Shu Xin include middle set, spiral, middle beam and pearl Son, the pearl bottom, which has, fills cream mouth, and the magnetic patch closed with the wicking of middle beam, the periphery of the spiral are provided in the tube body Upper to have several axially disposed convex keys, the inboard wall of tube body has a circle latch, is formed and convex key phase between adjacent latch The card slot of cooperation.

Preferably, the bottom of the middle Shu Xin is provided with the bushing of package spiral, and the bushing and magnetic patch are attracted.

It is furthermore preferred that flanging of the bottom of the bushing with beam core bottom surface in being formed.

It is furthermore preferred that being provided with the first limited step with the cooperation of bushing tip end face on the outer peripheral surface of the spiral.

It is furthermore preferred that the convex key both ends are connected with middle set and bushing respectively.

Preferably, the second limited step with the cooperation of middle set bottom end end face is provided on the outer peripheral surface of the spiral.

Preferably, the middle beam bottom has axially disposed guide groove, the spiral and middle beam axial restraint, circumferential It can relatively rotate, inner wall is provided with helicla flute, and the pearl is integrally located inside middle beam, and side wall is provided through guide groove and protrudes into The protrusion of helicla flute.

It is provided with several convex keys in the spiral of the utility model, and there is a circle card slot in tube body, so that middle beam core is inserted into Tube body does not have directionality, can arbitrarily assemble, furthermore with magnetic patch be attracted in Shu Xin, can fall out of tube body to avoid middle Shu Xin Out, it and is convenient for changing.

Specific embodiment

As shown in Figs. 1-5, the packing tube of a kind of lipstick or lipstick similar to cosmetics, including tube body 2 and middle beam core 1, middle beam 1 bottom of core is inserted into tube body 2, and tube body 2 is internally provided with the magnetic patch 22 attracted with the bottom of middle beam core 1.Magnetic patch 22 be and pipe The disc of intracoelomic cavity interference fit, can also be fixed by glue or other machinery structure.

Middle beam core 1 include middle set 11, spiral 12, middle beam 13 and pearl 14,12 inner wall of spiral be provided with helicla flute 121 and Annular groove 124, middle beam 13 pass through spiral 12, the guide groove 132 that bottom is provided with axially disposed, top have be bent to form with The bulge loop 131 that annular groove 124 cooperates, so that spiral 12 and the axially opposing fixation of middle beam 13, circumference is to can relatively rotate.Middle set 11 It is set in the intersection of spiral 12 and middle beam 13, mainly plays decoration functions, top has inside flanging 111, blocks it in Gap between beam 13.

Pearl 14 is integrally located inside middle beam 13, pearl bottom, which has, fills cream mouth, and lateral wall is set for containing lipstick cream It sets there are two protrusion 141, protrusion 141 passes through guide groove 132 and protrudes into helicla flute 141.The side of pearl is additionally provided with U-shaped open Mouthful, U-shaped opening forms elastic slice, has the salient point (not shown) for supporting middle 13 inner wall of beam on the outside of elastic slice.Pearl inner sidewall is set Also it is equipped with the fixture block 143 of fixed lotion.

In order to which Shu Xin in realizing and magnetic patch 22 are attracted, middle 1 bottom of beam core is additionally provided with the bushing 15 of package spiral 12, lining Set can use ferrous material, can also be made of the plastic material containing iron powder.In order to increase the suction-combining force, bushing 15 has shape At the flanging of middle beam core bottom surface.Bushing excessive slip in order to prevent causes spiral 12 to be exposed, and is provided on the lateral surface of spiral 12 With the limited step 122 of bushing tip end face cooperation.For the purposes of preventing the downward excessive slip of middle set 11, the outer peripheral surface of spiral 12 It is additionally provided with the limited step 123 with the cooperation of middle 11 lower end surface of set.

Several axially disposed convex keys 125 are provided between two limited steps, the inner wall of corresponding tube body 2 has One encloses latch, and the card slot 21 with the cooperation cooperation of convex key 125 is formed between adjacent latch, and guarantee tube body 2 and spiral 12 rotate synchronously.

Utility model works principle is as follows:

Middle beam core 1 is assembled, is inserted directly into tube body 2, the bushing 15 and magnetic patch 22 of bottom are attracted, and convex key 125 is caught in card In slot 21, so that tube body 1 and the circle of spiral 12 are circumferentially fixed.

In use, holding tube body 2, beam 13 in turn pushes protrusion 141 and moves along helicla flute 121, and pearl 14 is just in Beam 13 moves up and down, and realizes the flexible of lotion.

When needing replacing middle beam core 1, directly extract in beam core 1, new middle beam core is inserted into, due to convex key 125 Quantity far fewer than card slot, therefore the no directionality of assembly of middle beam core 1, replacement are convenient.
