Description

Container For Liquid Contents Of Novel Structure

The present invention relates to a container containing a liquid content of a novel structure, and more particularly, to a container in which a liquid content is contained and which is elastically deformed upon external pressure, and which is mounted at an inlet of the container and applied to the container. And a dropper through which the contents are discharged, wherein the dropper is positioned inside the container and discharges the liquid contents to the inner space between the second nozzles by the external pressure applied to the container. Nozzle; And a second nozzle for secondly discharging the liquid contents remaining in the inner space. It relates to a liquid contents containing container comprising a.

Dropper is a mechanism for ejecting a certain amount of the liquid contents stored in the container, and a variety of liquid contents, such as water, oil, emulsion, etc. can be easily ejected by a predetermined amount by gravity or pressure, the liquid content is generally It is mounted and used in a stored container.

The dropper is generally composed of a nozzle structure having an elongated channel whose cross sectional area or diameter increases in the discharging direction of the liquid contents so as to easily control the discharge amount while being discharged slowly by gravity or externally applied pressure.

When water is injected into a container equipped with the conventional dropper described above, for example, when the container is pressed by hand, a certain amount of water in the container is discharged through the dropper drop by drop by an external pressure, and when the external pressure is removed, Cohesion due to surface tension acts as a suction force, so that the water trapped in the nozzle is sucked into the container.

However, in the case of using a liquid content having a low surface tension or a high viscosity, it is difficult to expect the same effect as when water is injected with a conventional dropper structure. Specifically, a liquid content having a low surface tension or a high viscosity is used. The silver is not separated and discharged drop by drop, and is not sucked into the container even after the applied pressure is removed. This is because the surface tension of the liquid content is not as large as water, so that sufficient suction force due to cohesive force does not occur.

In addition, since the nozzle has a small diameter for controlling the discharge, it is also not easy to suck the liquid contents back into the container by standing the container after use.

Thus, the liquid content that is consumed unnecessarily flows down the outer circumferential surface of the dropper, and in this process is deteriorated due to direct contact with the external environment, thereby contaminating the nozzle.

In particular, when such liquid contents are medical liquid contents, not only the desired therapeutic effect may not be expected due to deterioration or contamination, but also may cause another disease, and economic efficiency may be reduced due to unnecessary consumption of expensive medical liquid contents. there is a problem.

In addition, for example, in the case of highly volatile liquid contents such as acetone, the small diameter of the nozzle causes the liquid contents to remain in the long and narrow channels of the nozzle, resulting in a change in composition due to volatilization, as well as cold storage. After use at room temperature, there is a problem that the liquid contents that remained in the channel flow outward due to the expansion of air.

US Patent Publication No. 2009/0026228 discloses a storage space for storing excess discharged liquid contents around a nozzle of a dropper insert to prevent contamination around the nozzle. However, the above-described prior art not only can not reduce the amount of unnecessary liquid contents, but also has a limit to become an inherent solution to the above problems.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-described problems of the prior art and the technical problems required from the past.

After extensive research and various experiments, the inventors of the present application have no inflow of air from the outside as described later, and as the liquid contents are discharged, the pressure in the inner space of the dropper is lower than atmospheric pressure, so that the pressure is opposite to the applied pressure. When the dropper is configured with a double nozzle structure to increase the suction force, the discharge amount can be easily controlled by using the suction force, and the liquid contents flow along the outer surface of the dropper to prevent deterioration and contaminate the nozzle. Since the liquid contents remaining in the channel are directly sucked into the container, it has been confirmed that volatilization and the resulting compositional change can be prevented and the present invention has been completed.

In another aspect, the present invention provides a container containing the liquid contents that can control the discharge time from the container of the liquid contents to the nozzle end by adjusting the size of the inner space of the dropper.

In addition, the present invention provides a container with a liquid content containing the liquid content of the liquid content is formed at the end of the nozzle so that the liquid content having a low surface tension or high viscosity does not flow along the outer peripheral surface of the dropper.

Thus, the container containing the liquid contents according to the present invention,

A liquid content-containing container having a liquid content therein, wherein the container is elastically deformed upon external pressure, and includes a dropper mounted at an inlet of the container and discharging the content by an external pressure applied to the container. Dropper,

A first nozzle located inside the container, the liquid content being first discharged to the inner space between the second nozzles by the external pressure applied to the container; And

A second nozzle for discharging secondly the liquid contents remaining in the inner space;

And is characterized by comprising:

In one preferred embodiment, the liquid contents containing container has a structure in which all parts except the nozzle is sealed so that outside air is not introduced, the dropper, and the hollow fastening portion projecting downward to be coupled to the inlet of the container; The structure may include a second nozzle extending upward from the hollow fastening part, and a first nozzle mounted inside the hollow fastening part or below the hollow fastening part.

As described above, the dropper according to the present invention is composed of a double nozzle structure of the first nozzle and the second nozzle, the liquid content when the external pressure is applied to the primary separation space formed between the first nozzle and the second nozzle primary And when the internal air of the inner space is reduced in proportion to the volume discharged to the first nozzle, the internal pressure of the inner space becomes lower than the atmospheric pressure so that the atmospheric pressure and the internal pressure are in equilibrium. Until the suction force occurs in the opposite direction to the external pressure.

Therefore, since the liquid contents discharged into the inner space are not discharged to the outside through the second nozzle, the liquid contents having a small surface tension or a high viscosity can be easily adjusted, and the liquid contents are deteriorated due to unnecessary consumption. Contamination can be prevented.

Specifically, after the first discharge, if the external pressure is continuously applied, the liquid content of the internal separation space is discharged to the outside through the second nozzle (second discharge), but if the pressure is removed after a predetermined amount of use, the internal separation by suction force Since it is sucked into the space and cannot be discharged to the outside through the second nozzle having a small diameter, it is easy to adjust the discharge amount and to prevent the deterioration of the liquid contents due to unnecessary consumption and contamination of the nozzle.

In addition, since the liquid contents remaining in the channel are sucked into the inner space and the container immediately after use by the suction force, the liquid contents that are unnecessarily consumed due to air expansion can be reduced even when used after refrigerated storage, and the composition due to volatilization Can be prevented, and even if the container collapses during use or during distribution, in the state where the second nozzle is blocked by the cap, air in the inner space prevents the liquid contents from flowing into the second nozzle. Unlike, no leakage occurs.

Furthermore, the present invention can suppress volatilization as much as possible by relatively shortening the length of the second nozzle (the length of the second channel). The inventors of the present application have found that when the length of the second nozzle is reduced by 80%, the loss of the liquid contents by volatilization is reduced by about 50%.

The suction force is not at all due to the cohesion force due to the surface tension of the liquid content itself, which is completely different from the mechanism of action of controlling the discharge amount of the liquid content having a large surface tension such as water.

The inner space is preferably at least larger than the volume of the liquid contents parallel to the discharge by the gravity of the liquid contents, and the suction force generated by the pressure drop accordingly, in particular, in consideration of the suction speed, etc. More preferably, it is formed at least 10% larger than the volume of. In one preferred example, the inner separation space is formed 10% to 80% larger than the volume of the parallel point.

The container and the dropper may be elastically deformed to increase the suction force as the discharge amount of the liquid content increases, but the material and the like are not limited, but are inexpensive, resistant to pressure and impact, and have a chemical resistance. It is preferable that it consists of.

Specifically, in the case of a dropper made of polypropylene plastic, it is desirable to secure an inner space of 0.2% or more of the total capacity.

When the inner separation space is formed to be less than 0.2% of the total capacity, since the internal pressure (negative pressure) acting in the direction opposite to the applied pressure does not occur, the liquid contents are directly discharged from the first nozzle to the second nozzle. It is not desirable because it can be.

That is, when an external pressure is applied to the body of the plastic container, in order to prevent the liquid contents from flowing out or falling out through the second nozzle from the first nozzle, an inner separation space of 0.2% or more of the total volume is secured to prevent the liquid contents from flowing out or falling. It is desirable to fill the liquid contents.

On the other hand, the larger the internal separation space or the structure that can delay the discharge amount and time before the liquid contents are discharged to the second nozzle, the suction force is increased, so that it is easier to discharge drop by drop, but the discharge time is long.

Therefore, in the container containing the liquid contents according to the present invention, the first nozzle is capable of adjusting the vertical position in the hollow inside of the hollow fastening portion, and its outer surface is in close contact with the inner surface of the hollow fastening portion by frictional force. It may be made of a structure.

The first nozzle may be manufactured to have a radius slightly larger than the radius of the hollow fastening portion and fixed at a desired position by a forced tightening method, or fixed at a desired position by forming a jaw in the dropper to be fastened. You can also

As described above, due to the mounting of the position-adjustable first nozzle, the present invention can control the time for discharging the liquid contents from the container to the outside through the second nozzle, thereby reducing the discharge time, thereby eliminating the need for internal separation space. It can also be used for liquid contents and, in particular, it does not require the manufacture of various molds, thereby reducing mold investment and maintenance costs.

Although the size, shape, and number of the first nozzles are not limited, when the size of the opening exceeds a certain size, even if no pressure is applied, the liquid contents may be discharged within a short time by gravity and external air may be introduced. Therefore, it is difficult to expect the effect of the present invention, and if it is too small, the discharge time is long, it is preferable that the air is formed in such a size that the air in the inner space is not penetrated into the container when the container is laid horizontally on the ground.

As one specific embodiment, the size of the opening of the first nozzle may be 1 to 3 mm in consideration of the surface tension, the viscosity, and the like of the liquid content, and according to the inventors of the present application, the aperture of one opening and the There is no difference in the suction force between a plurality of openings of relatively small aperture, but the leakage prevention effect is advantageous as the aperture is smaller, so that in the case of liquid contents having a small surface tension, the opening of the first nozzle formed by a plurality of openings of a small aperture The size of may be 1 to 3 mm. However, it can be determined fluidly in consideration of the discharge time.

If the size of the opening of the first nozzle is less than 1 mm, the discharging time is long, so it is not suitable for use. If the size of the opening of the first nozzle is 3 mm or more, the discharging time is the same as that of the case where the first nozzle is not attached, so that the first nozzle is installed. There is no.

In the case of a liquid content having a high viscosity, the size of the opening of the first nozzle may be increased. However, if the predetermined size is exceeded as described above, the effect of the present invention cannot be expected. Therefore, it is 2 mm in a larger range than the opening of the second nozzle. It is preferable that it is the following.

On the other hand, the opening of the second nozzle is more preferably 0.03 mm to less than 2 mm.

Preferably, the second nozzle may have an upward taper structure in which an inner surface adjacent to an upper end on a vertical cross section increases in diameter in an end direction, and as one specific embodiment, an upward taper angle of the second nozzle. May be 1 to 15 degrees.

The size and shape of the second nozzle determines the amount of one drop of liquid content discharged from the dropper and the property discharged, when the upward taper angle exceeds 15 degrees, the liquid content with low surface tension or high viscosity Is undesirable because it can flow along the outer circumferential surface of the dropper without being bound to the end of the second nozzle by its own surface tension.

In one preferred embodiment, in order to artificially adjust the amount of the liquid content formed at the end of the second nozzle, a portion or the entire inner surface of the second nozzle is formed with an uneven structure for preventing the discharge of the liquid content during the second discharge There may be. The uneven structure may be one selected from the group consisting of a spiral structure, a honeycomb structure, and a hook structure in plan view. With this structure, the leakage preventing effect due to the surface tension and the leakage preventing effect by the artificial structure can be exhibited in combination.

When the uneven structure is formed on a part of the inner surface of the second nozzle, it may be 30% to 95%, preferably 50% to 90% based on the entire inner surface of the second nozzle.

The depth (or height) of the unevenness may be determined by various factors such as the viscosity of the liquid content, the required discharge amount, and the like, for example, it may be desirable to be 0.01 mm to 0.1 mm.

In some cases, it may be considered to add a filler or a filter instead of the concave-convex structure, but in this case, the liquid contents may be deposited on the filler and the filter is not preferable because the effect of preventing the liquid is poor.

There is no restriction on the type of liquid content that can be stored and used in the container, but the liquid content of which the surface tension is smaller than the water or the viscosity is larger than that of the conventional dropper can exhibit an unexpected effect, and specifically, the surface tension is 10 to 72. dyne, or the liquid content with a solution viscosity of 1 to 10,000 cps.

As described above, the container containing the liquid contents according to the present invention is easy to control the discharge amount of the liquid contents by using the suction force of the inner space space formed by the double nozzle structure, the quality of the liquid contents due to unnecessary consumption, the nozzle Pollution can be prevented, and changes in composition due to volatilization can be prevented.

In addition, the present invention, even in the case of liquid contents having a low surface tension or high viscosity, the amount of the liquid contents formed in the second nozzle by using the surface tension of the liquid contents themselves and / or artificially hinder the flow of the liquid contents. By adjusting, the unnecessary consumption can be further prevented.
