Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vacuum cosmetic bottles, in particular to a plastic inner filling type vacuum cosmetic bottle. Background Art
[0002] At present, various cosmetics have emerged on the market. High-end and mid-range cosmetics are packaged in double-layer vacuum bottles, and the inner liner of the vacuum bottle is mostly a cylindrical liner made of plastic PP injection molding, which limits the shape of the outer bottle of the vacuum bottle, which can generally only be round or square. It stands to reason that square vacuum bottles are best to use square inner liners, which are more in line with the shape of the bottle, but in order to save costs, the existing round inner liners are generally used;
[0003] The existing vacuum bottle liner has a fixed shape, which also limits the shape of the outer bottle. In order to fit the liner, the outer bottle must be designed to be round. If the outer bottle is designed to be square, conical, diamond, or special-shaped, it will undoubtedly waste a lot of space. If you design a square, conical, diamond, or special-shaped liner separately, you have to redesign a liner mold, which not only increases the cost, but also requires redesigning the vacuum piston for other shapes of liner, which is more troublesome.
[0004] Therefore, in view of the above problems, a plastic inner filling type vacuum cosmetic bottle is now designed to better meet the actual use needs. Utility Model Content
[0005] The purpose of the utility model is to provide a plastic inner filling type vacuum cosmetic bottle to solve the problems raised in the above background technology.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a plastic inner-filled vacuum cosmetic bottle, comprising a bottle body, the bottle body and a bottle cap are interconnected, a vacuum pump head is installed on the bottle cap, the bottle cap and the protective cover are nested, the inner side of the bottle body is connected to a plastic inner-filled body, the vacuum pump head and a conduit are interconnected, and the conduit is arranged on the plastic inner-filled body.
[0007] Preferably, a threaded joint is fixed to the upper end of the bottle body, and an air hole is opened on the threaded joint, through which the air pressure inside and outside the bottle body can be balanced to ensure the normal use of the device.
[0008] Preferably, the threaded joint and the bottle cap are detachably threadedly connected, and the height of the bottle cap is smaller than the distance from the air hole to the upper end surface of the threaded joint. By limiting the height of the bottle cap, it is possible to avoid blocking the air hole after the bottle cap is installed and affecting the normal flow of gas.
[0009] Preferably, the bottle body and the plastic inner body are formed into an integrated structure through a blow molding process, and the plastic inner body is elastic and is made of PP material. The elastic plastic inner body can better fit the inside of the bottle body when the cosmetics are filled through the elastic effect of the plastic inner body to avoid space waste, and can automatically shrink when the cosmetics are used to facilitate better discharge of the cosmetics.
[0010] Preferably, four support bars are fixed at equal angles on the outside of the lower end of the conduit, and the support bars are in contact with the plastic inner body to achieve a supporting effect. A top block is also fixed to the lower end of the support bar, and the top block is in contact with the plastic inner body to achieve a supporting effect. Through the action of the support bars and the top block, the lower end of the plastic inner body can be supported, thereby preventing the plastic inner body from contacting the lower end of the conduit due to shrinkage of the plastic inner body during use, thereby affecting the normal discharge of the cosmetics.
[0011] Preferably, the distance between the upper end surface of the top block and the lower end surface of the conduit is 1 mm-2 mm. By limiting the position of the top block, it can be ensured that the cosmetics are discharged normally through the conduit.
[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: the plastic inner-filled vacuum cosmetic bottle adopts an elastic inner-filled structure, which can expand the elastic inner fill when the cosmetics are contained, so that the inner fill can be more conveniently fitted with the inner wall of the cosmetic bottle, thereby avoiding waste of internal space of the cosmetic bottle; and through the elastic effect of the inner fill, the piston structure can be removed when pumping out the cosmetics, and the elastic compression of the inner fill can facilitate the pumping out of the cosmetics; and through the supporting effect of the support strip and the top block, the clogging of the catheter port when the elastic inner fill contracts can be effectively avoided, thereby ensuring the normal use of the device.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1-Figure 3 The utility model provides a technical solution: a plastic inner-filled vacuum cosmetic bottle, comprising a bottle body 1, the bottle body 1 and a bottle cap 3 are connected to each other, a vacuum pump head 4 is installed on the bottle cap 3, the bottle cap 3 and a protective cover 6 are nested and connected, a plastic inner-filled body 2 is connected to the inner side of the bottle body 1, the vacuum pump head 4 and a conduit 5 are connected to each other, and the conduit 5 is arranged on the plastic inner-filled body 2.
[0019] A threaded joint 101 is also fixed to the upper end of the bottle body 1, and an air hole 102 is opened on the threaded joint 101; the threaded joint 101 and the bottle cap 3 are detachably threadedly connected, and the height of the bottle cap 3 is less than the distance from the air hole 102 to the upper end surface of the threaded joint 101; the bottle body 1 and the plastic inner body 2 are formed into an integrated structure through a blow molding process, and the plastic inner body 2 is elastic, and the plastic inner body 2 is made of PP material;
[0020] When using the plastic inner vacuum cosmetic bottle, Figure 1-Figure 3 As shown, firstly, the bottle body 1 and the plastic inner body 2 are made into an integrated structure by a blow molding process (wherein the bottle body 1 can be a round, square or diamond-shaped structure). When the cosmetics are filled, the elastic effect of the plastic inner body 2 can facilitate the plastic inner body 2 to fit with the inner wall of the bottle body 1, thereby avoiding the waste of the internal space of the bottle body 1. After the filling is completed, the assembly can be achieved by connecting the bottle cap 3 with the threaded joint 101. At this time, the conduit 5 is located in the plastic inner body 2.
[0021] Four support bars 501 are fixed at equal angles on the outer side of the lower end of the conduit 5, and the support bars 501 are in contact with the plastic inner body 2 to achieve a supporting effect. A top block 502 is also fixed at the lower end of the support bar 501, and the top block 502 is in contact with the plastic inner body 2 to achieve a supporting effect; the distance from the upper end surface of the top block 502 to the lower end surface of the conduit 5 is 1mm-2mm;
[0022] When taking cosmetics, Figure 1-Figure 3As shown, by pressing the vacuum pump head 4 and cooperating with the elastic contraction characteristics of the plastic inner body 2, the cosmetics inside the plastic inner body 2 can be pumped out through the conduit 5 and the vacuum pump head 4 for the user to take them out. As the cosmetics decrease, the plastic inner body 2 will slowly deform and shrink. Cooperating with the action of the air holes 102, the air flow inside and outside the bottle body 1 can be facilitated to ensure the normal contraction of the plastic inner body 2. When the plastic inner body 2 shrinks, the support bar 501 and the top block 502 can be used to ensure that the lower end of the plastic inner body 2 is always in an open state, thereby effectively avoiding the plastic inner body 2 from blocking the lower end of the conduit 5 when shrinking, thereby affecting the normal liquid discharge function and ensuring the normal use of the device. This is the working principle of the plastic inner vacuum cosmetic bottle.
