Description

Pump type container with plastic spring

The present invention relates to a pump-type container equipped with a plastic spring.

More specifically, it relates to a pump-type container that allows the contents contained in the main body to be discharged to the outside by a pressing operation of the pumping button unit, and has a steel spring structure that allows the pumping button unit, which has been previously pressed, to return to its original position. It relates to a pump-type container equipped with an eco-friendly plastic spring by substituting an elastic part of a plastic material.

Containers containing daily products in the form of fluids, which are widely used in daily life, are equipped with a small hand-operated pump, so that the contents are discharged out in a certain amount by simply pressing the pump, so it can be easily used.

Such a pump device is called a 'dispenser', and when the pump is pressed, contents contained in a chamber inside the pump are discharged to the outside through a nozzle.

At this time, when the force pressing the pump is removed, the pump is returned upward by the elastic force of the spring installed between the container and the pump, and the contents in the container are sucked into a chamber in the pump.

As an example of such a dispenser, it is used to conveniently discharge and use the shampoo solution contained in the shampoo container by a certain amount. In the past, a cap covered with a general lid and having an outlet through which the shampoo solution is discharged has been used, but inconveniences such as the need to pressurize the shampoo container have occurred. Due to the structural advantage of preventing the waste of the solution, it is installed and used in most shampoo containers.

On the other hand, the conventional pump container is provided with a pumping button unit for discharging the contents by a pressing operation, and a steel-type spring for applying elasticity so that the pumping button unit returns to its original state.

Such a steel-type spring has excellent elasticity so that the pump button part can be smoothly returned to its original state, but most of the pump containers are made entirely of plastic and the spring is made of metal, so the used pump container is separated and collected. During the process, it is difficult to separate and discard the plastic container and the metal spring, and thus, there is a problem in that the pump container cannot be recycled when discarded.

Furthermore, the steel-type spring has a risk of corrosion when in contact with the contents of the liquid contained in the container, and there is a problem that the contents are changed due to corrosion.

The present invention has been made to solve the above problems, and the problem to be solved in the present invention is to replace the spring structure of steel with an elastic part of plastic material so that the pumping button part, which has been pressed in the past, returns to its original position. By configuring it, it is to provide a pump-type container equipped with an environmentally friendly plastic spring.

In addition, the problem to be solved in the present invention is that in the process of compressing the elastic part of plastic material, a fullness phenomenon that becomes convex outward occurs. By forming an inclined tapered part at the end of the pumping button part that slides up and down, It is an object of the present invention to provide a pump-type container equipped with a plastic spring that allows the pumping button to move up and down flexibly along the exposed surface of the elastic part where the fullness phenomenon has occurred.

In addition, another problem to be solved in the present invention is that the elastic part in the form of a spring consists of a lower end and an upper end and an elastic rib connecting the lower end and the upper end, and the elastic rib is connected to the lower end and the upper end in a three-point manner, so that the elasticity It is an object of the present invention to provide a pump-type container equipped with a plastic spring capable of minimizing the occurrence of eccentricity by supporting the pumping button portion in a balanced manner in the process of repeating additional compression and return.

In order to solve the above problems, a pump-type container equipped with a plastic spring according to the present invention includes a main body having an opening hole opened upward to accommodate the contents; A lower pipe that is inserted into the opening hole and hung on the upper end of the main body and has a through hole passing through the upper and lower sides; a shoulder portion provided on the upper side of the lower pipe and having through-holes passing through the upper and lower sides; an upper pipe capable of sliding upward and downward through the through hole and provided with a discharge means for discharging contents accommodated in the housing in the through hole; an elastic part provided between the shoulder part and the upper pipe to elastically support the upper pipe; And a pumping button unit coupled to the upper side of the upper pipe; to solve the technical problem by providing a pump-type container equipped with a plastic spring, characterized in that the elastic part is made of a plastic material in the form of a spring.

The present invention is configured by substituting an elastic part of a plastic material for a spring structure of steel material, which allows the pumping button part to be returned to its original position, where a conventional pressing operation has been performed, so that recycling is easy and eco-friendly, and the contents are deteriorated due to corrosion. It has a remarkable effect that can prevent it in advance.

In addition, in the present invention, in the process of compressing the elastic part of plastic material, a swollen phenomenon occurs that is convex outward. It has a remarkable effect of allowing the pumping button to move up and down flexibly along the exposed surface of the elastic part.

In the present invention, the elastic part in the form of a spring is composed of a lower end and an upper end and an elastic rib connecting the lower end and the upper end, and the elastic rib is connected to the lower end and the upper end in a three-point manner, so that the elastic part repeats compression and return.

The extension part 320 is provided with an outer wall 330 and a fitting part 340 to be described later on each of the outer periphery and the inner periphery.

That is, as shown in the accompanying drawings, the outer wall 330 and the fitting portion 340 are spaced apart from each other by the extension portion 320 .

At this time, the extension part 320 is supported on the upper side of the locking jaw 220 of the lower pipe 200, and performs a function of supporting the lower surface of the elastic part 500 to be described later.

That is, the elastic part 500 in the form of a spring is between the extension part 320 of the shoulder part 300 and the pumping action part 410 of the upper pipe 400 inserted into the through hole 310 of the shoulder part 300. By being provided, the upper pipe 400 is slid upward and downward along the through hole 310 of the shoulder portion 300, and is moved downward by a pressing operation during the movement process, depending on the elasticity of the elastic portion 500. to return to the upper side by

The protruding ring 420 is formed in a form protruding toward the inner space on the side surface of the inner space of the pumping operation unit 410, and the lower surface is coupled with a discharge means provided in the inner space of the upper pipe 400, so that the upper pipe ( 400) performs a function of allowing the contents accommodated in the main body 100 to be moved upward by pumping as the discharge means moves up and down together in the process of sliding up and down.

Furthermore, as the upper surface of the protruding ring 420 supports the pressing wall 620 of the pumping button part 600 to be described later, when the pumping button part 600 is pressed downward, the pumping button part by a pressing operation. 600 and the upper pipe 400 are moved downward together.

At this time, the pumping button part 600 and the upper pipe 400 are moved upward by the elastic force of the elastic part 500 to be described later and returned to their original positions. Allow the contained contents to be expelled.

Hereinafter, the elastic part 500 provided between the shoulder part 300 and the upper pipe 400 will be described in detail with reference to FIGS. 5 to 9 .

5 is a front view showing an elastic part in a pump-type container equipped with a plastic spring according to the present invention, and FIG. 6 is a planar cross-sectional view showing an elastic part in a pump-type container equipped with a plastic spring according to the present invention.

The elastic part 500 is provided between the shoulder part 300 and the upper pipe 400 to perform a function of elastically supporting the upper pipe 400, and the lower part 510, the upper part 520 and the elastic rib ( 530).

As shown in FIG. 5 , the elastic part 500 is preferably formed in the form of a spring and may be made of a plastic material.

Therefore, when the pump container is disposed of, it can be recycled together with components other than the elastic part 500, making it easy to separate and collect, thereby enabling an environmentally friendly approach.

The lower end 510 is formed in a ring shape and is supported on the upper side of the extension part 320 of the shoulder part 300 .

The upper end 520 is formed in a ring shape to correspond to the lower end 510, and elastically supports the lower surface of the pumping operation unit 410 of the upper pipe 400.

The elastic rib 530 connects the lower end 510 and the upper end 520, but is made in a spiral shape so that the elastic part 500 is made in the form of a spring.

In this way, the elastic part 500 in the form of a spring is provided between the shoulder part 300 and the upper pipe 400 to elastically support the upper pipe 400, thereby moving the upper pipe 400 downward by a pressing operation. ) to return to its original position.

As this process is repeated, a pumping operation is performed so that the content accommodated in the main body 100 can be discharged to the outside by the discharge means provided in the upper pipe 400.

At this time, when the spring-type elastic part 500 is described with reference to FIG. 6 , it may be configured to be provided with three spaced apart from each other and connected to each of the lower end 510 and the upper end 520 in a three-point manner.

That is, three spiral-shaped elastic ribs 530 may be spaced apart from each other to connect the lower end 510 and the upper end 520.

This is because the three elastic ribs 530 are spaced apart from each other and connected to the lower end 510 and the upper end 520 in a three-point manner, so that the upper pipe 400 and the elastic part 500 repeat compression and return in the process. By supporting the pumping button unit 600 to be described later in a balanced way, the occurrence of eccentricity can be minimized.

For example, when the user eccentrically presses the pumping button part 600 outward relative to the central axis of the pumping button part 600 rather than pressing the entire pumping button part 600 downward, the elastic rib 530 is the lower part 510 and the upper part ( 520) Since they are connected to each other in a three-point manner, compression is achieved by supporting a uniform pressing force, thereby preventing the problem that the pumping button unit 600 is not flexible due to eccentricity.

Furthermore, the elastic part 500 composed of the lower end 510, the upper end 520, and the elastic rib 530 may have a stroke of 4.5 to 5 mm.

Preferably, the elastic part 500 may have a stroke of 4.7 mm.

Here, the stroke refers to the difference between the lengths in which the spring-type elastic part 500 is compressed and then returned in the reciprocating engine. When the stroke of the elastic part 500 is less than 4.5 mm, the elastic part The elastic force of 500 is strong, so a lot of force is consumed in the process of pressing the pumping button part 600, which will be described later, so there is a problem that the pumping operation is not performed smoothly, and if the stroke of the elastic part 500 is greater than 5 mm , There is a problem in that the elastic force of the elastic part 500 is low and the force to return the upper pipe 400 and the pumping button part 600 to the original position moved downward by the pressing operation is insufficient.

Depending on design conditions, as shown in FIG. 7 , the elastic part 500 may have upper and lower thicknesses of the upper end 520 smaller than upper and lower thicknesses of the lower end 510 .

This is because the three elastic ribs 530 are spaced apart from each other and connected to the lower end 510 and the upper end 520 in a three-point manner, thereby supporting the pumping button part 600 described later in a balanced manner to minimize the occurrence of eccentricity, and to minimize the occurrence of eccentricity. In the process of pressing the pumping button 600 downward, the pressing force is primarily transmitted to the upper end 520 made of a thinner thickness than the lower end 510, and the force resisting the pressing force is reduced by the thin thickness As the upper end 520 moves downward flexibly, it is possible to minimize the occurrence of eccentricity.

Depending on the design conditions, the elastic rib 530 of the elastic part 500 is made to have a rectangular cross section, as shown in FIG. 8, and an inclined surface 531 inclined from the top to the bottom is formed on the outer surface It can be.

The inclined surface 531 is in contact with the inclined surface 531 in the process of moving the inner wall 610 of the pumping button unit 600 to be described later up and down by a pressing operation so as to move flexibly downward, so that the elastic part ( 500) can prevent the problem that the normal return of the elastic part 500 is not achieved because the bottom surface of the inner wall 610 is caught on the upper surface of the elastic rib 530 in the process of repeating compression and return.

That is, in the process of moving the pumping button unit 600 up and down by a pressing operation, it is possible to prevent the problem that the inner wall 610 extending downward is caught by the elastic rib 530 of the elastic unit 500. .

Depending on the design conditions, the elastic part 500 is made in the form of a spring having a circular cross section through which the upper and lower sides are penetrated, and as shown in FIG. 9, the diameter of the cross section gradually decreases from the lower side to the upper side. can

That is, it may be formed in a form gradually narrowing toward the upper end 520 from the lower end 510 .

Therefore, when the elastic part 500 is compressed, the upper part 520 is moved downward by the force pressed from the upper side, and the eccentricity is applied to the upper part 520 because it is made of a structure having a narrower cross section toward the upper side. Even if it is, it limits the degree of being pushed outward so that it can move smoothly downward.
