Description

Container and manufacturing method thereof TECHNICAL FIELD [CONTAINER AND MANUFACTURING METHOD THEREOF}

The present invention relates to a container in which a liquid is accommodated, and more particularly, to a container in which a liquid capable of storing and discharging a liquid to be used without leaving any contents, and a method of manufacturing the same.

1A shows a storage container for liquid contents having viscosity according to the prior art.

Liquids such as shampoos and lotions are characterized by relatively high viscosity. The content 200 having such a high viscosity has a property of sticking to the inner wall of the container due to the viscosity of the content when it is contained in the container 100. However, these products are generally sold in a rigid container 100 having a small opening as shown in FIG. 1A for reasons such as aesthetics and convenience in use. That is, for reasons of consumer sensitivity or convenience of use, most of them are produced in a hard container of the type shown in FIG. 1A. In the method of discharging the contents, generally, a pump is installed in the discharge unit 300 for convenience of use. Attached to the pump action by pneumatic pressure, a method of sucking and discharging the contents through the discharge pipe 310 is used. However, it is not a problem if the contents 200 are sufficient in the storage space of the container 100 and the contents can be discharged through the discharge pipe 310, but if the contents are not left in the container 100, the remaining contents Since it sticks to the inner wall of the container and does not fall off easily, it causes a problem that it is difficult to discharge the remaining contents, which acts as a major obstacle to the neat use of the contents such as shampoo and lotion.

Figure 1b shows a state in the container when the remaining contents are not much left in the storage container of the viscous liquid contents according to the prior art.

As shown in FIG. 1B, when the amount of the remaining contents 210 is small, the remaining contents 210 are attached to the inner wall of the container 100 so that they are not easily separated from the container 100, and the discharge pipe 310 attached to the pump. ), there is a problem in that the remaining contents 210 in the container cannot be effectively discharged because the area that can be inhaled is limited. This problem causes the following serious problems by making it difficult to use because a significant amount of the contents attached to the inner wall of the container cannot be properly discharged.

First, the contents remain out of reach of the hard container, and the contents cannot be used completely and are discarded, thereby promoting excessive consumption.

Second, if the container is discarded while the contents such as lotion, shampoo, detergent, etc. are left, it can cause environmental pollution.

Third, if the discharge port such as a pump is separated from the container and the discharge port is opened to use the remaining contents in the container that is not discharged by the discharge device, the contents may be contaminated due to the inflow of foreign substances.

Fourth, in order to discharge the contents remaining in the container, there is a problem in that it is difficult to accurately discharge the amount to be used when discharging is attempted by separating the container and the dispenser and shaking off the container.

On the other hand, in order to solve the above problems, an airless container has been introduced that reduces the volume by raising the bottom plate of the container according to the use of the contents.However, in the case of such a container, the bottom plate of the container is raised by reducing the pressure of the contents. It is unsuitable for, and above all, it is possible to implement only a cylinder-shaped container, so the freedom of container design also acts as a large limitation, and there is a problem that the cost increases in container manufacturing.

Therefore, there is a need for an introduction to a container and a method capable of effectively injecting and discharging viscous contents while maintaining aesthetics and convenience by using a hard container, and producing at low cost.

1. Korea Utility Model Registration No. 0289892 (Name of design: container using a hot air balloon)

The inventor of the present invention relates to a case where a liquid, especially a highly viscous liquid, is contained in a hard container with a narrow opening, when the liquid content adheres to the inner wall of the container due to the viscosity and surface tension of the liquid content, and the remaining content is insufficient. The problem was recognized that it was not practical because it was difficult to discharge. Nevertheless, we fully recognize the voice of the related industry that hard containers can only be used for hard containers due to the reason that they make the product look luxurious in terms of aesthetics, and that it is necessary to attach a pump to the discharge part for convenience of use. Was doing.

Accordingly, the inventor of the present invention puts an elastic pouch (elastic pouch) in a rigid container and stores the liquid contents in the elastic pouch, so that the contents stored inside the rigid container can be conveniently and completely used through a new and innovative method. Containers and devices were devised.

Relatedly, as introduced above, in order to easily discharge the contents even when the remaining amount of the contents is low by providing the elastic pouch in the hard container, a process of filling the contents into the elastic pouch must be accompanied at the manufacturing stage of the product. .

2A and 2B illustrate a process of filling a hard container with a liquid in a general manufacturing process such as shampoo and lotion.

As shown in FIG. 2A, in the case of a product sold by putting liquids in a hard container such as shampoo or lotion, hard containers are arranged in a row on the transfer device 500 and transferred to the contents filling equipment (510). The contents filling equipment may have one to a plurality of nozzles 600 depending on the design.

As shown in FIG. 2B, when the hard container is positioned below the nozzle according to the number of nozzles, the nozzle goes down above the opening of each hard container and fills the contents through the nozzle (610). At this time, the time that the nozzle moves to fill the contents and the amount of filling per unit time of the nozzle are directly related to the production efficiency of the product. Therefore, in general, the nozzle is vertically moved only a minimum distance according to the design method so that the contents can be accurately contained in the hard container. However, the contents are sprayed on the spot without moving, and for this reason, the openings of the nozzle and the hard container are mostly filled with spaced apart from each other in consideration of production efficiency.

On the other hand, the inventors of the present invention believe that when filling the contents into the elastic pouch through the corresponding method, the injection pressure of the contents injected through the opening of the hard container is sufficient to overcome the elasticity of the elastic pouch because of the elasticity of the elastic pouch. It is also recognized that if the contents are not injected while the contents injection nozzle is in close contact with the hard container, the elastic pouch is inflated and the contents cannot be contained as much as the volume of the hard container.

Therefore, in consideration of economical efficiency, development of a new type of container device and a method of manufacturing the same that can contain contents in an elastic pouch while using the existing contents filling equipment as it is required.

Accordingly, the problem to be solved of the present invention is a device, a container, and a method for manufacturing the same that can use all the contents without leaving a viscous liquid in a container device capable of storing and discharging a liquid according to the present invention. To provide.

Another problem to be solved of the present invention is that by providing an elastic pouch that can be inserted into a hard container, the surface area reduction effect according to the contraction of the elastic pouch and the elasticity (resilience) of the elastic pouch allows the contents of the elastic pouch toward the opening. By utilizing the pushing pressure and the discharge pressure of the discharge device, the remaining contents can be used effectively, and due to the elasticity of the elastic pouch, when the elastic pouch is swollen, it can be transformed into various shapes that a hard container can have. It is to provide a device, a container, and a manufacturing method for the container design, regardless of the shape of the hard container.

Another problem to be solved by the present invention is to use a method in which the filling nozzle sprays or flows the contents above the opening of the hard container as in the conventional method when filling the contents in a hard container equipped with an elastic pouch, the elastic pouch In the state that is not expanded in advance, it is impossible to inject the contents as much as the volume of the hard container due to the elasticity of the elastic pouch.Therefore, a device, a container and a container capable of injecting contents using a conventional filling method while having an elastic pouch It is to provide a manufacturing method for this.

In close contact, the outer container side opening 121 can be closed.

Hereinafter, the manufacturing process of the container according to the embodiment of the present invention will be described in detail.

6 to 9 are views showing the manufacturing process of the container of FIG.

First, referring to FIG. 6, first, in a state in which the coupling unit 200 is coupled to the outer container 100, the filling space 311 of the pouch 300 is located in the receiving space 111 of the outer container 100. As much as possible, the container 1 is prepared by installing the pouch 300 in the outer container 100.

At this time, the container 1 is prepared in a state in which the pump unit 400 is not disposed in the container 1.

Then, referring to FIG. 7, the elastic pouch 300 is expanded using the container manufacturing apparatuses 500 and 600.

The container manufacturing apparatuses 500 and 600 according to an embodiment of the present invention are devices for manufacturing a container 1 including a pouch 300 made of an elastic material to suppress the remaining of the filled contents during use.

When filling liquid contents such as cosmetics or detergent, the existing liquid contents are simply poured into the container 1 in which the pouch 300 is coupled to the outer container 100 without separately applying pressure to the liquid contents. In the case of using the filling facility, a problem occurs in that the pouch 300 is not sufficiently expanded within the accommodation space 111 of the external container 100.

That is, when the existing filling facility is used, the weight of the liquid contents accommodated in the filling space 311 of the pouch 300 in a contracted state is less than the elastic force, that is, the restoring force of the pouch 300, and the pouch 300 is The contracted state is maintained, and there is a problem in that the desired amount of the liquid content is not filled in the pouch 300.

Therefore, the container manufacturing apparatus 500 and 600 used in the container manufacturing method according to the embodiment of the present invention, in a state in which the outer container 100 and the pouch 300 are combined, the pouch 300 by a predetermined size. By expanding, securing a sufficient filling space 311 and maintaining the pouch 300 in an expanded state, it is possible to solve a problem that occurs when the existing filling facility is used.

The container manufacturing apparatuses 500 and 600 according to the embodiment of the present invention include a stage unit 600 and an air pressurization/decompression unit 500.

The stage unit 600 includes a stage unit body 610 in which the outer container 100 is mounted and the bottom surface 117 of the outer container 100 contacts, and the stage unit body 610 includes an external pump 700 An air intake hole 620 connected to and communicating with the through hole 112 of the outer container 100 is formed.

The air pressurization/decompression unit 500 includes an air pressurization/decompression unit body 510 that is movable in an up-down direction and has a rounded end and extends in the same direction as the length direction of the outer container 100. An air flow path 520 is formed in the center of the pressurization/decompression unit body 510 and an air flow hole 511 communicating with the air flow path 520 is formed at the end of the air pressurization/decompression unit body 510.

Hereinafter, a process of expanding the elastic pouch 300 of the container 1 by using the container manufacturing apparatuses 500 and 600 will be described in detail.

The prepared container 1 is mounted on the stage unit 600, and at this time, the container 1 is placed so that the through hole 112 of the external container 100 and the air intake hole 620 of the stage unit 600 communicate with each other. Align.

Then, the air pressurization/decompression unit body 510 is moved toward the filling space 311 through the pouch side opening 321 of the pouch 300 installed in the outer container 100 so that the pouch 300 is elastically deformed. Do (pouch stretching step). At this time, the air pressurization/decompression unit body 510 is slid downward so that the end of the pouch 300 does not contact the inner surface of the outer container 100. Since the end of the air pressurization/decompression unit body 510 is formed to be round, the inner surface of the pouch 300 in contact with the end of the air pressurization/decompression unit body 510 is damaged by friction or excessive contact pressure. Can be minimized.

Then, in a state in which the filling space 311 of the pouch 300 is elongated downward by a predetermined size, the air pressure/depressurization unit 500 presses the filling space 311 of the elastically deformed pouch 300 to atmospheric pressure. The pressure is reduced to the following first reference pressure _reduction pressure P _NR1 . That is, a negative pressure is provided to the air flow path 520 of the air pressurization/decompression unit 500, and air in the filling space 311 is sucked through the air flow hole 511.

When the filling space 311 is decompressed to the first reference decompression pressure P _NR1 , a portion of the inner surface of the pouch 120 is adsorbed and fixed to the air pressurization/decompression unit 500 (pouch decompression step).

And, in a state in which the filling space 311 is depressurized to the first reference decompression pressure (P _NR1 ), the accommodation space 111 of the external container 100 is at atmospheric pressure through the air intake hole 620 of the stage unit 600 The pressure is reduced to the following (external vessel pressure reduction step) At this time, as a part of the inner surface of the pouch 300 is adsorbed and fixed to the air pressurization/reduction unit 500, when the receiving space 111 is depressurized, the pouch 300 is elastically deformed into an unintended shape, that is, the pouch ( A portion of the 300) may be prevented from being sucked into the through hole 112 of the outer container 100.

Meanwhile, in the present embodiment, it is described that the filling space 311 is depressurized and then the receiving space 111 is depressurized, but the decompression process may be performed simultaneously.

At this time, the first reference decompression pressure (P _NR1 ) may be equal to or smaller than the second reference decompression pressure (P _NR2 ), and the accommodation space 111 of the outer container 100 has a through hole 217. Only through, it can communicate with the outside of the accommodation space 111.

Next, referring to FIG. 8, when the internal pressure of the accommodation space 111 is reduced to a second reference decompression arm force (P _NR2 ) or less, the air pressurization/decompression unit 500 is applied to the filling space 311. Provides a reference pressurization pressure (P _PR ) equal to or greater than atmospheric pressure. When the pressure of the accommodation space 111 is the second reference pressure _reduction pressure P _{NR2 that} is less than the atmospheric pressure, and a reference pressure pressure P _PR greater than the atmospheric pressure is applied to the filling space 311, the pouch of the pouch 300 The body 221 is instantaneously expanded within the receiving space 111 of the outer container 100 (pouch pressing step).

At this time, the filling space 216 of the pouch 210 is a portion far from the opening 215 of the outer container 100, that is, a portion adjacent to the other side 212 of the outer container 100, and a portion close to the opening 215 That is, a portion adjacent to one side 2123 of the outer container 100 is simultaneously expanded.

That is, when the air pressurization/decompression unit 500 provides the reference pressurization pressure (P _PR ) to the filling space 311 without a decompression process for the receiving space 111 of the external container 100, air pressurization/decompression As the air flow hole 511 of the unit 500 is expanded from the end 123 side of the pouch 210 positioned relatively adjacent to each other, the pouch 300 may be unevenly expanded. When the pouch 300 is unevenly expanded, the first expanded portion of the pouch body 310 touches the inner wall side of the outer container 100, and according to the expansion of the pouch 300, the accommodation space 111 of the outer container 100 ), the flow path through which the air in the through hole 112 flows may be closed, and thus, the expansion of the pouch 300 may not be performed to the desired size.

Accordingly, in the present embodiment, by uniformly expanding the pouch 300 within the receiving space 111, the pouch 300 may be smoothly expanded.

On the other hand, the air pressurization/decompression unit 500 according to the present embodiment is described as a configuration that only depressurizes or pressurizes the inside of the filling space 311, but a liquid for supplying the liquid contents l to the filling space 311 A configuration including a content supply hole is also possible.

That is, in a state in which the filling space 311 is depressurized to the first reference depressurized pressure (P _NR1 ) and the accommodation space 111 is depressurized to the second reference depressurized pressure (P _NR2 ), the liquid contents in the liquid contents supply hole If (l) is supplied, the pouch 300 can be expanded to atmospheric pressure or a pressure close to atmospheric pressure when the liquid contents are supplied. In addition, a configuration in which the pouch 300 is expanded by providing the liquid content at a pressure higher than atmospheric pressure is also included in the embodiment of the present invention.

Meanwhile, in the depressurization process of the receiving space 111, external air may partially flow into the receiving space 111 through the fine pores of the outer container 100, but the receiving space 111 through the stage unit 600 ), the hourly discharge amount of air discharged to the outside of the receiving space 111 is greater than the hourly inflow amount of air flowing into the receiving space 111 through the void, so that the internal pressure of the receiving space 111 gradually decreases. do.

Next, referring to FIG. 9, in a state where the filling space 311 of the pouch 300 is expanded to a desired size, the through hole 112 of the outer container 100 is maintained in order to maintain the expanded state of the filling space 311. Install the blocking member (S) in ).

The blocking member (S) blocks the inflow of air through the through hole 112 formed in the outer container 100, so that the outer container 100 is in a state where the pressure between the pouch 300 and the outer container 100 is formed. It suppresses the inflow of air through the through hole 112 from the outside of the. Accordingly, when the liquid content (l) flows into the filling space 111 through the outer container side opening 121 of the pouch 300, the expanded state of the pouch 300 may be maintained.

That is, in a state in which the pouch 300 is disposed in the outer container side opening 121 of the outer container 100, the accommodation space 111 is closed with respect to the outer container side opening 121, and the pouch body 300 The filling space 311 extends from the receiving space 111 of the outer container 100. In this case, the volume of the expanded filling space 311 may be formed to be smaller than the volume of the receiving space 111. That is, in a state where the pouch 300 is expanded to a predetermined volume, the filling space 311 of the pouch 300 does not completely fill the accommodation space 111, and a part of the accommodation space 111 may remain. . Accordingly, some of the outer surface of the pouch body 310 may be in contact with the inner surface of the outer container 100, and other parts may be maintained in a state not in contact with the inner surface of the outer container 100. Since all the outer surfaces of the pouch body 310 are not in contact with the inner surface of the outer container 100, damage to the pouch body 310 due to contact friction between the inner surface of the outer container 100 and the outer surface of the pouch body 310 Can be suppressed.

In the state where the filling space 311 is expanded from the receiving space 111, the pressure inside the filling space 311 is the same as the atmospheric pressure, and the receiving space located between the filling space 311 and the inner surface of the outer container 100 ( The pressure of 111 is formed less than the internal pressure of the filling space 311.

In this situation, by installing the blocking member (S) on the outer surface of the outer container 100, air can be blocked from flowing into the receiving space 111 through the through hole 112 of the outer container 100.

At this time, the pressure of the filling space 311 of the pouch 300 is formed to be smaller than the restoring force of the pouch 300, and is applied to the inner surface of the pouch 300 by the pressure of the filling space 311 of the pouch 300. The force applied to the outer surface of the pouch 300 by the force and the pressure of the space between the pouch 300 and the outer container 100 is in equilibrium with the restoring force of the pouch 300.

In the state where the air pressurization operation by the air pressurization/decompression unit 500 and the decompression operation of the air by the stage unit 600 are finished, the filling space 311 is maintained in an expanded state in the accommodation space 111 When disposed on the blocking member S and the through hole 112 side, the pouch 300 of the container 1 is maintained in an expanded state. By pouring the liquid content (l) into the filling space 311 side of the pouch 300 through the pouch side opening 321 of the pouch 300 maintained in an expanded state, providing a high pressure supply pressure during liquid filling The liquid content (l) can be filled into the container (1) using an existing filling facility that does not.

The blocking member (S) of the container manufacturing method according to the present embodiment may be an adhesive member such as a sticker for preventing air from flowing into the through hole 112. However, the blocking member (S) may be a valve means such as a check valve that selectively blocks the movement of air, and when the blocking member (S) is formed of the check valve, in the preparation stage of the container 200, blocking The member (S) may be provided in a state installed in the outer container (100).

Meanwhile, in the present embodiment, the air pressurization/decompression unit 500 is described as a configuration in which air is filled in the filling space 311 of the pouch 300, but the air pressurization/decompression unit 500 directly transfers the liquid contents to the pouch. A configuration for filling the filling space 311 of 300 may also be included in an embodiment of the present invention.

In addition, in the present embodiment, the through hole 112 is described as a configuration in which a through hole 112 through which air can flow is formed in the bottom surface 117 of the outer container 100, but the through hole 112 is an external container. A configuration formed on a member positioned between the coupling unit 200 or the pump unit 400 and the outer container 100 or other positions such as the neck portion 120 of 100 is also included in the embodiment of the present invention.

In addition, in the case of the container manufacturing method of the container 1 according to the embodiment of the present invention, by installing the blocking member (S) on the through hole 112 side, the expanded pouch 300 of the container 1 It is described as a configuration in which the filling space is prevented from being reduced again, and then the liquid content (l) is filled in the container 1, but the pressurizing operation of the filling space 311 of the air pressurization/decompression unit 500 is terminated. However, a configuration in which the liquid content l is filled in the filling space 311 is also included in the embodiment of the present invention while the decompression operation on the accommodation space 111 of the stage unit 600 is maintained. In this case, the liquid content (l) is directly filled in the filling space 311 in the air pressurization/decompression unit 500 in which a separate liquid content movement flow path is formed, or the air pressurization/decompression unit 500 is removed. The liquid content supply unit may fill the liquid content l with respect to the filling space 311 side.

According to the proposed embodiment, there is an advantage of minimizing the occurrence of residues of liquid contents, minimizing the use of plastic, and suppressing environmental pollution by using a material that is smoothly recycled or has excellent biodegradability.

In addition, there is an advantage of being able to fill a liquid content in a container including an elastic pouch and an external container in which the pouch is installed, using an existing filling facility.

10 and 11, the outer container body 110 of the outer container 100 of the container 1 according to this embodiment is formed on the other side of the outer container body 110, that is, the bottom surface 117 And, it includes a pouch expansion check unit 113 that can be deformed in shape according to the expanded state of the pouch 300.

The thickness of the pouch expansion check portion 113 is formed to be smaller than the thickness of the other portion of the outer container body 110 adjacent to the portion where the pouch expansion check portion 113 is formed, that is, the bottom surface 117. The thickness of the pouch expansion check unit 113 is formed to have a size such that the pouch expansion check unit 113 is elastically deformable by a pressing force applied from the pouch 300 during the expansion of the pouch 300.

The pouch expansion check unit 113 includes a concentric groove portion 114 and a check portion side connection portion 115 connecting the groove portion 114 and the bottom surface 117, and the groove portion 114 is The shape of the expansion check part 117 is changed.

That is, before the pouch 300 is expanded within the receiving space 110 of the outer container 100, the pouch expansion check unit 113 is depressed toward the receiving space 110 with respect to the bottom surface 117 Is formed by
