Description

Plastic cement Oil-free middle bundle core

Technical field

The present invention relates to lipstick or lip-stick package technical field, more particularly to a kind of plastic cement Oil-free middle bundle core.

Background technology

Lipstick or lipstick are the cosmetics that women is commonly used, and mill run is that lipstick cream is placed in packing tube, during carrying, Lotion is hidden in packing tube, it is necessary to which in use, turn packing tube exposes by lotion.Existing packing tube is by base, lid With middle beam core composition, base and lid mainly play protection and decorative effect, and middle Shu Xin is its core component.

Common middle Shu Xin is made up of middle beam, spiral, four parts of fork and pearl, to reach preferable feel and outer See, the material of middle beam is generally aluminum pipe, and outer surface plating metal coating.

As CN201533649U discloses a kind of lipstick tube beam core without glue, including pearl, fork, spiral and middle set, Snap ring notch between the spiral and middle set provided with axial arranged keyway arrangements and circumferentially.

And for example CN201767295U discloses a kind of middle Shu Xin of lipstick tube, including sequentially coaxially wears from outside to inside Beam, spiral, fork and pearl, middle beam are fixedly connected with spiral, and spiral inner peripheral surface is provided with spiral helicine guide groove, the wall of fork It is provided with face along its axially arranged notch, is provided through notch on pearl outer peripheral face and stretches into the projection of guide groove.Spiral bottom Some salient points being fixed on spiral inner peripheral surface or on fork outer peripheral face are provided between end and fork.

Beam core is made up of four parts in disclosed in above-mentioned patent, and structure is relative complex, and manufacturing cost is higher.

The content of the invention

The invention provides a kind of middle Shu Xin, existing middle beam cored structure complexity, the problem of manufacturing cost is high are solved.

A kind of middle Shu Xin, is made up of the pearl, fork and spiral that coaxially wear, and spiral inwall is provided with helicla flute, fork With axially disposed guide groove, the pearl outer wall has the salient point that helicla flute is stretched into through guide groove.

It is preferred that, the spiral, fork and pearl are made by plastic cement.

It is preferred that, there is the first bulge loop and the second bulge loop of limitation spiral axial movement on the outer wall of the fork.

It is preferred that, the inside top of the spiral has the limited step being engaged with the first bulge loop.

It is preferred that, the inside spiral has the annular groove being engaged with the first bulge loop, and the annular groove is located at spiral Lower section.

It is preferred that, the spiral oral area has the in-flanges coordinated with fork top.

It is preferred that, second bulge loop is engaged with the bottom end face of spiral.

It is preferred that, the outer wall of the fork is provided with the shell fragment for supporting spiral.

It is preferred that, there is the otch that its top end is extended to from guide groove on the fork.

Beam core is only made up of pearl, three parts of fork and spiral in the present invention, and three parts can be all using plastic cement Material, reduces middle beam, structure is more simplified, and manufacturing cost is lower relative to existing middle Shu Xin.

Embodiment

As depicted in figs. 1 and 2, Shu Xin is made up of spiral 1,3 three parts of fork 2 and pearl in the present invention, and three Part is plastic cement material, and plastic cement can be PV, PC or other high molecular polymers.Three coaxially wears together, wherein, The inwall of spiral 1 has two helicla flutes 11, and fork 2 is provided with two along its axial arranged guide groove 21, and the outer wall of pearl 3 is provided with Two projections 31, projection 31 is stretched into helicla flute 11 through guide groove 21.

As shown in Fig. 2 the oral area of fork 2, which has, originates in guide groove 21, the otch 22 on its top is extended to, when assembling pearl During son 3, pearl 3 can just strut the oral area of fork 2, be easily installed.As indicated at 3, there is bulge loop 23 on the top outer wall of fork, The inwall of the corresponding oral area of spiral 1 has the limited step 12 coordinated with bulge loop 23.As shown in figure 4, on the outer wall of the bottom of fork 2 The bulge loop 24 coordinated with the bottom end face of spiral 1 is additionally provided with, the limitation spiral 1 of bulge loop 23,24 is moved axially with respect to fork 2.

Also shown in FIG. 4, the bottom terminal ends medial surface of spiral 1 has annular groove 13 so that between fork 2 and spiral 1 With certain gap, the position in the gap, the outer wall of fork 2 is provided with the shell fragment 25 for supporting spiral 1, shell fragment 25 and spiral There is frictional force between 1, the feel that fork 2 and spiral 1 are relatively rotated can be lifted.

As shown in figure 5, another embodiment of the invention, beam core is same by spiral 1, fork 2 and 3 three, pearl in this Part is constituted, and internal assembling structure and foregoing middle beam core are essentially identical, and difference is only in that fork 2 to spiral 1 axially The mode of limitation.

As shown in figure 8, the top of fork 2 does not have bulge loop, but bulge loop 26 is provided with the top of shell fragment 25.Such as Fig. 7 institutes Show, bulge loop 26 and the annular groove 15 of the bottom of spiral 1 coordinate, the bottom end face of bulge loop 24 and spiral 1 coordinates, and limitation spiral 1 is relative Fork 2 is axially moved.As shown in fig. 6, because the top of fork 2 no longer has bulge loop, the oral area of spiral 1 has the top of fork 2 The in-flanges 14 that end coordinates.The one side of in-flanges 14 can increase aesthetics, on the other hand can avoid due to the oral area of spiral 1 It is excessively sharp and hurt consumer.

Operation principle of the present invention is as follows：

Because spiral 1 is with respect to the axial restraint of fork 2, the projection 31 on fork 2, turn spiral 1, the outer wall of pearl 3 is pinched in spiral shell Moved in spin slot 11, due to the limitation of axially disposed guide groove 21, pearl 3 can only pump inside fork. Lotion bottom is contained in inside pearl 3, in pearl motion process, and top can expose spiral 1, and then can use.In order to increase Plus lotion is contained in the firmness in pearl 3, the inwall of pearl 1 has in convex tendon 32, embedded lotion.
