Description

Dispenser for recycling

The present invention relates to a dispenser that is easy to recycle, and in particular, to a dispenser that can be used not only to facilitate resource recycling but also to handle corrosive liquids by being composed of parts made of only plastic material without metal parts.

In Korea, in accordance with Article 19 of the 「Framework Act on Resource Recycling」 (evaluation of hazards and recycled availability of products, etc.), the circular availability evaluation system has been implemented since 2018. Recycling availability evaluation is a system that recommends that when a product is disposed of, the factors that hinder recycling are evaluated and areas that need improvement are reflected from the product design stage.

By evaluating the factors that hinder the recycling of waste products, we recommend improvement to product producers and, if improvement is not implemented, the evaluation results are disclosed. Evaluation subjects include the Ministry of Environment and the Korea Environmental Industry & Technology Institute, and the Ministry of Environment publishes the evaluation results on the Internet, etc. if the producer does not implement the improvement recommendations according to the evaluation results, and promotes best practices of products that have been properly implemented.

Accordingly, in order to improve recycling, technology has been developed to unify the materials of accessories of products such as labels, lids, dispensers, etc., and the single material of containers and labels has been commercialized, but pump caps that are widely used in detergents and cosmetics have been developed. Developing with a single material is still in the introductory stage.

Accordingly, there is a need to improve the resource recycling rate by configuring the conventional dispenser as a single part made of plastic material without metal parts.

At this time, in the dispenser 200 according to the first embodiment of the present invention, a through rod portion is provided in the container 201 by penetrating through the third insertion opening 265 from the first insertion opening 235, and specifically, the through rod portion is FIG. 1 And as shown in FIG. 3, the second rod 206, the third check valve C23, and the third rod are sequentially connected below the first penetrating rod of the discharge portion 202 through the stepped member 204 ( 270), a fourth check valve C24, and a fourth rod 280.

Here, the third rod 270 may form four locking ends along the upper circumferential surface on the upper side to be engaged with the inside of the third insertion hole 265 of the stopper 260.

In addition, the third check valve (C23) and the fourth check valve (C24) are valve structures made of only plastic, like the first check valve (C21) and the second check valve (C22) described above, and have a ball shape inside. Since there is a fluid, it is usually close to the bottom to prevent the fluid from flowing downward, and during operation, it is a valve structure that is opened so that the fluid flows only upward. That is, the first check valve C21 to the fourth check valve C24 are valve structures that allow fluid to flow upward and prevent fluid from flowing downward.

The dispenser 200 according to the first embodiment of the present invention configured as described above has a cross-section shown in FIG. 3 after assembly, and as the user presses the discharge part 202, the locking protrusion 202-4 becomes a stepped member ( When moving downward along 204, the second rod 206 also moves downward and the fourth check valve C24 is locked by the pressure pressed from the top, and the fluid in the third rod 270 is as much as the moving length. The corresponding amount is discharged to the discharge part 202 through the third check valve C23.

At this time, in the restoration process after discharge, the second rod 206 including the third check valve C23 returns upward, the third check valve C23 is closed, and the fourth check valve C24 is opened and The amount corresponding to is introduced into the third rod 270 through the fourth rod 280 and restored.

Specifically, as the user presses the discharge unit 202, the first bellows 211, the second bellows 212, and the third bellows 213 shown in FIG. 2 are compressed at the same time.

At this time, due to the relationship between the volume and pressure, the space of the pressure passage Vi3 having a relatively small total internal volume has a higher pressure than the space of the pressure preservation passage Vp3, and is shown by the dotted arrow in FIG. 4 due to the increased pressure. As described above, some air existing in the pressurizing flow path Vi3 flows into the space of the pressure preserving flow path Vp3 through the second check valve C22.

Here, the pressure passage Vi3 is connected to the space Vi formed by the second bellows 212 and the third bellows 213, as shown in FIG. 4, and the third lower ring 219 Through hole 219-2, first through hole 232, first side groove 262, first check valve (C21), 11th through hole 242, 33rd through hole 243 and second It is an air flow path including the line groove 264.

In addition, as shown in FIG. 5, the pressure preserving flow path Vp3 includes the 44th through-hole 244, the 22nd through-side hole 246, the pressure-preserving space VP4 from the second check valve C22, as shown in FIG. Air including a space Vp formed by the second through hole 236 and the first bellows 211 and the second bellows 212 connected to the through holes 217-6 of the first lower ring 217 It's euro.

Thereafter, when the user releases the pressure of the discharge unit 202, the elasticity of the first bellows 211, the second bellows 212, and the third bellows 213 and the inside of the pressure preserving flow path Vp3 It returns to its original state due to the cause of the pressure being higher than atmospheric pressure.

That is, even when the volume of the pressure preserving flow path Vp3 is restored, the amount of air increases by the amount introduced from the pressurizing flow path Vi3, and the air introduced from the pressurizing flow path Vi3 through the second check valve C22 It is stored in the space Vp formed by the first bellows 211 and the second bellows 212 while passing through the pressure preserving flow path Vp3 and the pressure preserving space Vp4 upon release. Accordingly, as the pressure in the pressure preserving flow path Vp3 has a pressure higher than atmospheric pressure, the first bellows 211 and the second bellows 212 connected to the pressure preserving flow path Vp3 expand.

At the same time, the first check valve C21 is opened in the pressurization flow path Vi3 as shown by a solid arrow in FIG. 4 to allow external air to pass through the first side groove 262 to the eleventh through hole 242 and the first It flows into the space Vi formed by the second bellows 212 and the third bellows 213 through the through hole 232 and the through hole 219-2 of the third lower ring 219, Atmospheric pressure.

At this time, since the pressure in the pressure preserving flow path Vp3 is greater than atmospheric pressure, the first bellows 211 and the second bellows 212 connected to the pressure preserving flow path Vp3 expand and get caught by this pressure difference. The first penetrating rod and the cap 203 having the jaws 202-3 formed on the sides are raised and prepared for the next use.

When this process is repeated several times, the pressure of the pressure preserving flow path Vp3 gradually increases and converges to the maximum pressure of the pressurizing flow path Vi3.

Accordingly, even if the dispenser 200 according to the first embodiment of the present invention is continuously used, the pressure of the pressure preserving flow path Vp3 only converges to the maximum pressure of the pressurizing flow path Vi3, but does not increase infinitely. , Due to this pressure difference, the space Vp between the first bellows 211 and the second bellows 212 connected to the pressure preserving flow path Vp3 is expanded to facilitate the return operation for the next use.
