DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 4 In this embodiment, a plastic container for cosmetics includes a plastic container body 1 and an anti-extrusion shell 2 arranged on the outside of the plastic container body 1. The top of the plastic container body 1 is provided with a leak-proof structure to prevent leakage of cosmetics. The leak-proof structure includes a cover body 3 threadedly connected to the top of the plastic container body 1, and a squeeze pump 4 extending into the interior of the cover body 3 is installed on the top of the cover body 3. A limiting sleeve 5 extending into the interior of the cover body 3 is provided on the outside of the squeeze pump 4. A return spring 6 is fixedly connected to the interior of the limiting sleeve 5, and one end of the return spring 6 is fixedly connected to an elastic block 7 extending into the interior of the cover body 3. Positioning strips 8 are fixedly connected to the front and back of the squeeze pump 4.

[0025] Among them, the number of return springs 6 and elastic blocks 7 are both two, and a card slot adapted to the elastic card block 7 is opened inside the cover body 3. The number of card slots is twice that of the elastic card block 7. The front and back sides of the limit sleeve 5 are both provided with positioning slots adapted to the positioning strip 8, and the top of the extrusion pump 4 is fixedly connected to an extrusion head 9.

[0026] Among them, the two elastic blocks 7 are symmetrically distributed on the left and right sides of the limiting sleeve 5, and the positioning bar 8 is located at the top of the limiting sleeve 5. When the user rotates the limiting sleeve 5, it can be rotationally limited. Then, by setting the positioning bar 8, when the positioning bar 8 and the positioning groove are on the same vertical line, the extrusion pump 4 can be squeezed. When the positioning bar 8 and the positioning groove are misaligned, the extrusion pump 4 can be positioned, thereby achieving the effect of facilitating the locking of the extrusion pump 4, thereby preventing the cosmetics from leaking.

[0027] In this embodiment, the bottom of the extrusion pump 4 is fixedly connected to a delivery pipe 10 extending into the interior of the plastic container body 1, the bottom end of the delivery pipe 10 is fixedly connected to a sealing gasket 11, and the left and right sides of the delivery pipe 10 are fixedly connected to liquid inlet heads 12 connected thereto.

[0028] The outer surface of the sealing gasket 11 is in contact with the inner wall of the plastic container body 1 , and the bottom of the sealing gasket 11 is in contact with the inner bottom wall of the plastic container body 1 . The sealing gasket 11 is made of silicone.

[0029] It should be noted that by providing the delivery tube 10 and the liquid inlet head 12, it is convenient to squeeze out the cosmetics. By providing the sealing gasket 11, when the user lifts the extrusion pump 4 together with the sealing gasket 11 upward, the cosmetics on the inner wall of the plastic container body 1 can be scraped off, avoiding waste of cosmetics.

[0030] In this embodiment, a threaded groove 13 is provided on the outer surface of the plastic container body 1 and the opposite side of the inner wall of the anti-extrusion shell 2. The connection between the plastic container body 1 and the anti-extrusion shell 2 is a threaded connection, and a perspective opening 14 is provided on the surface of the anti-extrusion shell 2.

[0031] The transparent opening 14 is provided to facilitate the user to check the amount of liquid inside the plastic container body 1 , and the anti-extrusion shell 2 is made of acrylic material.

[0032] In this embodiment, the bottom end of the anti-extrusion shell 2 is fixedly connected to a fixed cover 15, and the external thread of the fixed cover 15 is connected to a sealing cover body 16. By providing the fixed cover 15 and the sealing cover body 16, it is convenient for users to store the powder puff, thereby improving the space utilization of the device.

[0033] The working principle of the above embodiment is:

[0034] First, the user unscrews the cover 3, then injects cosmetics into the plastic container body 1, and then covers the cover 3. At the same time, the top of the delivery tube 10 is connected to the inside of the cover 3. Then, the user puts the anti-extrusion shell 2 on the outside of the plastic container body 1 and tightens the anti-extrusion shell 2. At this time, the user can also place the powder puff inside the sealing cover 16 and cover the sealing cover 16 with the outside of the fixed cover 15. When the user needs to pack the plastic container body 1, the user can rotate the limiting sleeve 5 so that the positioning bar 8 is misaligned with the positioning groove, and the extrusion pump 4 cannot be pressed normally. When the cosmetics need to be squeezed out, the limiting sleeve 5 is rotated again so that the positioning bar 8 is aligned with the positioning groove, and then squeezed.

[0035] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or device comprising the element.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
