Description

Push type cosmetic packaging tube

Technical Field

The utility model relates to a cosmetics field, more specifically relates to a cosmetics packaging tube of push type.

Background

In the original society, when some troops are in sacrifice activities, animal grease can be smeared on the skin, so that the skin color of the troops looks healthy and glossy, which is the earliest skin care. It follows that the history of cosmetics can be estimated almost from the presence of humans. During the period from the first 5 th century to the 7 th century, there are many descriptions and descriptions about the production and use of cosmetics in various countries, such as curling hair with clay for ancient Egypt, drawing eye-circles with verdigris after ancient Egypt, bathing body with donkey milk, covering wrinkles with fish gelatin for ancient Greek American jaba, etc., and many cosmetics have appeared. Ancient China also prefers to wipe the cheeks with rouge, moisturize the hair with hair oil, and set off the beauty and charm of the face. Formulations for beautifying, preserving or modifying the appearance of the human body or for cleaning, dyeing, rubbing, correcting or protecting the skin, hair, nails, eyes or teeth, i.e. cosmetics.

The cosmetics are chemical industry products which are well known by people, belong to the field of fine chemical engineering, and mainly refer to chemical industry products or fine chemical engineering products which are uniformly distributed on any part of the surface of a human body, such as hair, face, neck, armpit, nail, lip and tooth, and the like by smearing, spraying and other methods so as to achieve the purposes of cleaning, maintaining, beautifying, decorating, changing appearance and the like and keep people in good state. With the acceleration of social development, cosmetics are also developed. In the case of lip gloss, a conventional lip gloss package is generally divided into two parts, one of which is a bottle with a screw mouth for containing contents, and the other part is a screw cap matched with the mouth of the bottle body, wherein a rod with a cotton head or a brush head is arranged in the screw cap and can be used for dipping the contents in the bottle. When the product is needed, the user only needs to unscrew the screw cap to dip the contents from the bottle by using the brush head connected to the cap body for smearing, and after the contents are evenly smeared, the brush body is inserted back into the bottle and the screw cap is screwed down. The packaging design for such cosmetics has drawbacks. The method mainly comprises the following two steps: firstly, due to the designed structure and the use mode, the quantity of the contents dipped by the brush head is completely determined by the viscosity of the contents and the adhesive force of the brush head, and the quantity of the contents dipped by the brush head cannot be manually controlled in an external intervention mode. Just because the volume of dipping in the content can't artificial control, consequently can often need stretching into the bottle repeatedly when using this product and dip in the content and come out to scribble, thereby the in-process brush head of scribbling can be contaminated with external contact, then can bring the pollutant including bacterium etc. into the bottle when the brush head gets into the bottle once more and breed and multiply a large amount of bacterium in the bottle and cause the shortening of this type of product shelf life. Secondly, once the package of the product is disassembled, the service life of the product is short due to the structure and the use mode of the product, the product needs to be used as soon as possible after being unsealed, otherwise, the content in the bottle is easy to deteriorate. Therefore, there is a need for a push-type cosmetic packaging tube that is convenient and sanitary and can prolong the shelf life of cosmetics.

The working principle and the working process of the pressing type cosmetic packaging tube of the embodiment are briefly described as follows:

the cosmetics packaging tube of a push type of this embodiment includes: the liquid outlet mechanism 1, the pump core 2, the liquid storage bottle 3 and the dust cover 4, wherein the pump core 2 is arranged in the bottle mouth of the liquid storage bottle 3, and the top of the pump core is connected with the liquid outlet mechanism 1. When cosmetics are not used, the dust cover 4 is sleeved on the liquid outlet mechanism 1, the bottom of the dust cover is abutted against the liquid storage bottle 3, the internal environment of the packaging tube can be effectively prevented from being polluted by dust or bacteria, and the cosmetics are prevented from going bad. When cosmetics are used, the dust cover 4 is pulled out, the stepped structure 101 of the liquid outlet mechanism 1 is pressed, pressure generated by pressing action is transmitted to the pump core 2 through the liquid outlet mechanism 1, and power for operation is provided for the pump core 2, so that the pump core 2 extracts the cosmetics in the liquid storage bottle 3. The pump core 2 pumps the cosmetics to the liquid conveying channel of the liquid outlet mechanism 1, and the liquid outlet mechanism 1 conveys the cosmetics liquid to the hollow silica gel head 102 through the liquid conveying channel of the liquid outlet mechanism for use by a user. The pump core 2 is a main part of the push-type cosmetic packaging tube, so that the quantity of the prepared cosmetics is controlled according to the size of the pressing force of a user, and the cosmetics are more convenient and flexible to use. The pump cartridge 2 is constituted by the following components: the connecting rod 41, the spring 42, the connecting seat 44, the piston 32, the feeding rod 33, the pump body 21 and the valve plate 23; the assembly process is as follows: firstly, the spring 42 and the connecting seat 44 are sleeved on the connecting rod 41, then the piston 32 is sleeved on the feeding rod 33, and the feeding rod 33 sleeved with the piston 32 is inserted into a hole below the connecting rod 41, so that the two rods are fixed to form the piston structure 22 with the spring 42. The valve plate 23 is then placed in the bottom of the pump body 21, and finally the piston structure 22 is installed in the pump body 21 to form a complete pump core 2. When the pump core 2 works, the process that the pump core 2 pumps out the cosmetics in the liquid storage bottle 3 is divided into two links: namely, the liquid outlet mechanism 1 is pressed, and the pump core 2 descends after force is transmitted to the pump core 2 through the liquid outlet mechanism 1; a liquid outlet mechanism 1 is loosened, and the pump core 2 rebounds and then moves upwards; these two links constitute a complete pump core 2 working cycle.

The user presses the liquid outlet mechanism 1, pressure is continuously applied to the stepped structure 101 of the liquid outlet mechanism 1, so that the connecting rod 41 of the pump core 2 moves downwards to compress the spring 42, at the moment, the piston 32 in the pump body 21 is separated from the first limiting structure 34 at the bottom of the material inlet rod 33 under the action of friction force generated by the inner wall of the pump body 21, the inlet of the second transfusion channel arranged at the rod body of the material inlet rod 33 is not blocked by the piston 32, the channel state is changed from closed to open, cosmetic liquid or air enters from the inlet of the second transfusion channel of the material inlet rod 33, and the piston structure 22 pumps the cosmetic liquid or air in the pump body 21 into the liquid outlet mechanism 1; the liquid outlet mechanism 1 transports the cosmetic liquid to the hollow silica gel head 102 through the self liquid conveying channel for the user to use. Subsequently, the user releases the tapping mechanism 1 and no more pressure is applied. The connecting rod 41 and the feeding rod 33 of the pump core 2 move upwards under the action of the resilience force of the spring 42, the feeding rod 33 moves upwards, the piston 32 abuts against the first limiting structure 34 at the bottom of the feeding rod 33, the piston 32 blocks the inlet of the second liquid conveying channel of the feeding rod 33, and the channel state is changed from open to closed; the pressure inside the pump body 21 continuously decreases to form negative pressure under the action of the piston 32 continuously ascending, the pressure in the bottle body of the liquid storage bottle 3 is greater than the pressure in the pump body 21, so that the sealing piece 82 in the valve plate 23 is opened at the bottom of the pump body 21 under the condition of uneven pressure on the upper and lower planes, and the cosmetic liquid in the liquid storage bottle 3 can enter the pump body 21. When the pressure inside the pump body 21 is balanced with the pressure inside the liquid storage bottle 3, the sealing piece 82 returns to the opening position at the bottom of the pump body 21 again under the action of the tension rib 83, and the passage between the inside of the pump body 21 and the inside of the bottle body is closed again, so that the cosmetics are taken once.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the technical solutions of the present invention, and are not limitations to the specific embodiments of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
