Description

Packing structure for pumping a gel material

The present invention relates to a packing structure of a liquid pump used to extrude liquid contents from a cosmetic container, and more particularly, minimizes the liquid contents remaining inside the container body and increases the discharge pressure of the liquid contents to increase the liquid contents. The present invention relates to a packing structure of a liquid pump that is easily discharged and prevents leakage when assembling a support to a container body.

In general, the liquid pump installed and used in the cosmetic container serves to discharge the liquid contents contained in the container by a predetermined amount out of the container. Referring to FIGS. 1 and 2, the conventional liquid pump is as follows. .

Referring to FIG. 1, an opening and closing rod 3, a spring 4, and a piston member 5 are installed in a cylinder 2 coupled to a support 1, and a push rod coupled to the piston member 5. The cap (7) is fitted to (6). A sheet 2a on which the bowl 8 is seated is formed at the lower end of the cylinder 2 so that the bowl 8 opens and closes its lower inlet. Then, in order to seal the container body 9 and the supporter 1, a ring frame 1b was formed inside the main body cover part 1a of the supporter 1 to press-fit the upper part 9a of the container body 9. In addition, as shown in FIG. 2, the packing 13 is positioned between the upper part of the container body 9 and the support 1 to maintain airtightness, and the piston 10 is positioned at the lower part of the container body 9 to provide liquid contents. It was made to raise gradually with discharge of (11).

Because of this, the conventional designs had some problems. First, it is not easy to assemble during the production of the product. Second, there is a problem of waste to dispose of the product even though a large amount of liquid content remains inside the container. Also, liquid content is easy due to the low pumping pressure due to the large amount of air inside the container. There was a problem that can not be discharged. This will be described in more detail as follows. When assembling the conventional design of FIG. 1, the upper part 9a of the container body 9 is press-fitted and coupled between the main body cover part 1a and the ring frame 1b of the support body 1 to prevent leakage. The upper cover 9a of the support body 1 and the annulus frame 1b are formed to be narrower than the thickness of the upper portion 9a of (9), and then the upper portion 9a of the container body 9 must be forcibly inserted. . Therefore, the body cover part 1a or the annulus 1b of the support body 1 is frequently broken at this time, which lowers the reliability of the product and the body cover part 1a is bulging even if the product is not damaged. There was a problem that swelled out of the product aesthetically unfavorable.

And the conventional design of Figure 2 is to put the packing 13 correctly on the upper portion (9a) of the container body (9) when assembling the product and then gently insert the support (1), when the packing (13) Frequently falling or being pushed into the container body (9) occurred, making the assembly of the product difficult. Since the liquid contents 1 are contained in the container body 9, the container body 9 cannot be turned upside down and inevitably put the packing 13 on the narrow upper portion 9a of the container body 9 to be combined. There was no choice but to. As described above, the conventional solutions not only had a problem in assembly, but also had a problem that a large amount of liquid contents remained. That is, when the cap 7 is pressed to discharge the liquid contents, the push rod 6 and the piston member 5 are lowered to push the piston member 5 and the opening and closing rod 3 downward, and the cap ( 7) When the pressing operation is stopped, a gap is formed between the bowl 8 and the sheet 2a of the cylinder 2 in the process of raising them again by the spring 4, and the liquid contents rise upward. There is also a gap between the (3) and the piston member 5 so that the liquid contents (11) can be distributed, which is due to the lowering of the piston member (5) and the opening and closing rod (3) inside the cylinder (2) Since the pressure changes, the liquid contents 11 contained in the cylinder 2 are discharged out through the discharge hole 12 of the cap 7, and the valve 10 is discharged as the liquid contents 11 are discharged. Gradually rises. However, in the liquid pump shown in FIGS. 1 and 2, the piston 10 rises only until it reaches the lower end of the cylinder 2, so that an unnecessary space S is formed, so that the liquid content 11 is contained in the container body 9. In spite of the fact that much remains unnecessary, the contents are not easily discharged, so the user tends to discard it without knowing it, which is very uneconomical. Also, in the case of a new product, an air layer (S) is present in the original container body (9). It acted as a problem of lowering the pumping force of).

Therefore, the present invention has been devised to solve the conventional problems as described above, the object of the present invention is to effectively prevent the leakage of the container body and facilitate the assembly and at the same time the liquid contents remaining inside the container body It is to provide a packing structure of the liquid pump to maximize the pumping force of the cylinder by minimizing the amount of air in the container body to minimize the need to satisfy the consumer's desire.

In order to achieve the above object, the present invention is fitted with a cylinder is coupled to the inside of the support, the opening and closing rod is elastically raised by a spring inside the cylinder, the lower portion of the cylinder by the pressure difference generated inside the cylinder In the packing structure of the liquid pump to open and close the lower part to supply the liquid contents contained in the container body into the cylinder to discharge the liquid contents between the opening and closing rod and the piston member: a packing is inserted between the inner wall of the container body and the outer wall of the cylinder It is a technical configuration feature to prevent leakage between the container body and the support, to facilitate product assembly, and to minimize the remaining space of the liquid contents formed between the inner wall of the container body and the outer wall of the cylinder.

According to the present invention, the piston accommodated in the container body is formed to have an external shape defined by the packing and the lower part of the cylinder so that the liquid contents are completely discharged when the piston is fully raised to the cylinder side, the packing is engaged with the cylinder and has a circular frame It is preferable that the first elastic portion and the second elastic portion engaged with the container body and having a ring frame are formed, and the annular protrusions are formed in the cylinder and the container body so that the ring frames are respectively accommodated to maintain airtightness.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is a cross-sectional view of the liquid pump according to the present invention, the same reference numerals as in Figure 1 and 2 in Figure 3 represents the same parts, detailed description thereof will be omitted, essential configuration of the present invention Only the elements are described.

As can be seen in FIG. 3, when the packing 50 is fully raised to the cylinder 2 side as shown in FIG. 4 by inserting the packing 50 between the inner wall of the container body 9 and the outer wall of the cylinder 2. Compared with the prior art FIGS. 1 and 2, the remaining space of the liquid contents formed between the inner wall of the container body 9 and the outer wall of the cylinder 2 can be minimized.

Therefore, the piston 100 accommodated in the container body 9 is formed to have an outer shape defined by the packing 50 and the lower part of the cylinder 2 so that the liquid content (when the piston 100 is fully raised toward the cylinder 2 side) 11) was completely discharged.

In addition, the packing 50 is engaged with the cylinder 2 and has a first elastic portion 51 having an annulus 51a, and a second elastic portion engaged with the container body 9 and provided with an annulus 52a ( 52, the annular projections (2b) (9b) are formed in the cylinder (2) and the container body (9) so that the ring edges (51a) (52a) are each accommodated to maintain airtightness. Therefore, when assembling the container body 9 and the support body 1, the packing 50 is first inserted into the container body 9 and then assembled to facilitate assembly, as well as the first elastic part 51 of the packing 50. Due to the elasticity of the second elastic portion 52) and to maintain the airtightness of the container to prevent damage during assembly.

Therefore, the present invention prevents leakage between the container body 9 and the support body 1 by inserting the packing 50 between the inner wall of the container body 9 and the outer wall of the cylinder 2, and at the same time facilitates assembly work. Since the piston 100 is formed to be the same as the outer shape of the packing 50, the piston 100 is raised close to the cylinder 2 side, so that unnecessary space S as shown in FIGS. 1 and 2 is not formed. Likewise, the liquid content 11 may not only remain in the container body 9 but also have an advantage of improving the pumping force by minimizing the presence of air in the container body 9.

According to the present invention as described above, by installing the packing in the space between the cylinder and the container body, and by forming a piston that is raised when the discharge of the contents in the same shape as the packing, the liquid contents do not remain between them completely discharged the product Not only can it improve the reliability of the device, but also prevents leakage between the container body and the support, and is an effective design that facilitates the assembly work.
