Description

Technical Field

[0001] The present invention relates to a pouch unit, a container device including the pouch unit, and a content filling device for filling the same.

Background Art

[0002] FIG. 1A is a diagram showing a storage container for a viscous liquid content according to the prior art.

[0003] Liquids such as shampoo and lotion are characterized by relatively high viscosity. When such a highly viscous content 20 enters the container 10, it has the property of sticking to the inner wall of the container due to the viscosity of the content. However, for reasons such as aesthetics and ease of use, such products are generally sold in a hard container 10 having a relatively small opening as shown in FIG. 1A. That is, for reasons such as consumer sensibility and ease of use, most are produced in a hard container in the form shown in FIG. 1A. However, in the method of discharging the content, generally, for ease of use, a method is used in which a pump is attached to the discharge part 30 and the content is sucked and discharged through the discharge pipe 31 by the pumping action of air pressure. However, when the content 20 is sufficient in the storage space of the container 10 and the content can be discharged through the discharge pipe 31, there is no problem. However, when there is not much content left in the container 10, the remaining content sticks to the inner wall of the container and does not easily fall off, causing a problem that it is difficult to discharge the remaining content. This acts as a major obstacle factor in not being able to use up the content such as shampoo and lotion.

[0004] FIG. 1B is a diagram showing the state inside the container when there is not much remaining content 21 in the storage container 10 for a viscous liquid content 20 according to the prior art.

[0005] As shown in FIG. 1B, when the amount of the remaining content 21 is small, not only does the remaining content 21 adhere to the inner wall of the container 10 and not easily fall from the container 10, but also the area that the discharge pipe 31 attached to the pump can suck is limited. Therefore, there is a problem that the remaining content 21 in the container cannot be effectively discharged. Such a problem causes the following serious problems by making it difficult to use the container properly without discharging a considerable amount of the content adhering to the inner wall of the container.

[0006] First, the content remains in the inaccessible part inside the rigid container, so that the content cannot be completely used up and is discarded, which promotes overconsumption.

[0007] Second, when the container is discarded with the content such as lotion, shampoo, and detergent remaining, it may cause environmental pollution.

[0008] Third, when separating the discharger such as a pump from the container and opening the discharge port to use the remaining content in the container that cannot be discharged by the discharger, the content may be contaminated due to the inflow of foreign matters or the like.

[0009] Fourth, when separating the container and the discharger to discharge the remaining content in the container, turning it upside down and hitting it to try to discharge, there is a problem that it is difficult to accurately discharge the amount to be used.

[0010] Fifth, there is a problem that the remaining amount of the content remains in the outer container, making it difficult to recycle or reuse the container.

[0011] On the other hand, in order to solve the above problems, an airless container in which the bottom plate of the container rises and the volume decreases due to the use of the content has been introduced. However, in the case of such a container, since the bottom plate of the container is pulled up due to the pressure reduction of the content, it is not suitable for a large-capacity container. Moreover, only a cylinder-shaped container can be realized, which acts as a great restriction on the degree of freedom of the container design and increases the cost in the manufacture of the container.

[0012] Therefore, there is a need for a container and method that can be produced at low cost while maintaining aesthetics and convenience using a hard container, and can effectively inject and discharge viscous contents.

[0013] In addition, in the prior art, a container device that can be used to minimize remaining contents by applying a pouch having elastic restoring force has been proposed, but in order to fill the container device with contents, the pouch comes into contact with a nozzle that fills the contents, and the nozzle physically stretches the pouch, which may cause damage such as perforation of the pouch.

[0014] Therefore, there is a need for a container device that can stably fill the contents while preventing damage to the pouch.

[0015] In addition, in the conventional technology, when a pouch having elastic restoring force expands and contracts, if the pouch comes into contact with the inner surface of a hard container, frictional force may be generated between the pouch and the hard container depending on the material of the pouch, and this frictional force may prevent the pouch from expanding as the contents are filled into the pouch. Similarly, frictional force may be generated between the pouch and the hard container during the process of the pouch contracting as the contents filled in the pouch are pumped and reduced by the discharge part, and this frictional force may prevent the pouch from contracting as the contents are discharged from the pouch.

[0016] Therefore, there is a need for a pouch and a container device in which the pouch can easily expand and contract in response to the filling and discharging of the contents.

[0017] In addition, in the conventional technology, when filling a pouch with contents, there is a risk that the pouch may be caught inside the hard container due to the pressure of the contents. In addition, in the conventional technology, in order to fill the pouch with contents, the pouch must be physically stretched and the pouch must be tightly attached around the nozzle that provides suction force to supply the contents, and there is a problem that the configuration of the contents filling device becomes complicated to perform these operations.

[0018] Therefore, there is a need to introduce a container device and / or a content filling device that can sufficiently fill the pouch with contents while simplifying the structure and configuration.

Summary of the Invention

Problems to be Solved by the Invention

[0020] The inventor of the present invention recognized that when a liquid, especially a highly viscous liquid, enters a rigid container with a narrow opening, due to the viscosity and surface tension of the liquid content, the liquid content adheres to the inner wall of the container, and when the remaining content is very small, it is difficult and impractical to discharge the remaining content using a pump or the like. Nevertheless, the inventor fully recognized the voices in the related industrial fields that the rigid container has to be used because it makes the product look high-class in terms of aesthetics and because it is necessary to attach a pump or the like to the discharge part for the convenience of use.

[0021]

[0022] Regarding this, as described above, in order to easily discharge the content even when there is not much remaining content in a rigid container equipped with an elastic pouch, the process of filling the elastic pouch with the content must be involved in the manufacturing stage of the product.

[0023] Figures 2A and 2B are diagrams showing the process of filling liquids into a rigid container in common manufacturing processes such as shampoo and lotion.

[0024] As shown in Figure 2A, in the case of products in which liquids such as shampoo and lotion are placed in a rigid container and sold, the rigid containers are arranged in a row on the conveying device 50 and conveyed to the content filling equipment (51). The content filling equipment can have one to a number of nozzles 60 depending on the design.

[0025] However, as shown in Figure 2, when conventional filling equipment has to be used, there is a problem that air in the outer container has to be removed in advance because the elastic pouch has to be expanded in advance for filling, and there is a problem that foreign substances can flow into the expanded elastic pouch between the elastic pouch and the content filling.

[0026] In addition, there is a problem that the outer container has to be punched to remove the air in the outer container, and after expanding the elastic pouch, there are problems that air outflow prevention sealing has to be performed or decompression has to be maintained to maintain the expanded state of the elastic pouch for filling.

[0027] Therefore, the problem to be solved by the present invention is to provide a device and a container that can put a viscous liquid into the container device capable of storing and discharging the liquid according to the present invention and can use all of the content without leaving any residue.

[0028] In addition, the problem to be solved by the present invention is to provide a pouch unit, a container device, and a content filling device that can effectively use the remaining content by utilizing the pressure of the elastic pouch pushing out the content toward the opening and the discharge pressure of the discharge device due to the surface area reduction effect caused by the contraction of the elastic pouch and the elasticity (resilience) of the elastic pouch provided with an elastic pouch that can be inserted into a rigid container, and can be deformed into various forms that the rigid container can have when the elastic pouch expands due to the elasticity of the elastic pouch, so that the container can be designed without being restricted by the form of the rigid container.

[0029] The problem to be solved by the present invention is to provide a content filling device that can hygienically and efficiently fill a flexible pouch with content while satisfying the condition that the flexible pouch must be expanded into a form and size corresponding to the shape of the outer container in order to inject the content, a container device filled by the device, and a pouch unit included in the container device.

[0030] Another problem to be solved by the present invention is to provide a pouch unit and a container device in which the friction with the inner surface of the container is minimized when the flexible pouch expands while being filled with content and when the flexible pouch contracts while the content is discharged from the flexible pouch for use, due to a certain shape of the flexible pouch filled with content.

[0031] Another problem to be solved by the present invention is to provide a container device in which at least a part of a pump unit or a nozzle of a content filling device is inserted into a selective seal unit disposed at the upper part of the flexible pouch to enable filling or discharging of the content, and the content filled in the pouch does not flow out externally when the pump unit or the nozzle of the content filling device is not inserted.

[0032] Furthermore, the problem to be solved by the present invention is to provide a content filling device in which a part is inserted into a selective seal unit to fill the flexible pouch with content, and the selective seal unit maintains a sealed state when filling the content.

[0033] The problems of the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the following description.

[0042] Also, the outer peripheral surface of one end portion of the pouch unit body is formed to correspond to the outer peripheral surface of the at least one pouch unit body recess.

[0043] On the other hand, a container device including a pouch unit according to the disclosed embodiment of the present invention includes a pouch unit formed of an elastic material and having a filling space for filling a liquid therein, and a selective seal unit that is coupled to the upper portion of the pouch unit and selectively communicates the filling space of the pouch unit with the outside.

[0044] Also, the hardness of the selective seal unit is formed to be greater than the hardness of the pouch unit.

[0045] Also, the selective seal unit includes a seal unit support portion in which at least a part of the upper portion of the pouch-side locking portion where the pouch unit is placed and supported on the upper portion of the outer container is in surface contact, and a seal unit body that is formed to extend from the inner peripheral surface of the seal unit support portion and extends a predetermined length toward the pouch unit body side of the pouch unit.

[0053] The present invention is for solving the above problems, and the container device according to the present invention has an effect of providing a pouch unit, a container device, and a content filling device that can contain a viscous liquid and use all of the content without leaving any residue.

[0054] The device, container, and method for manufacturing the same according to an embodiment of the present invention include an elastic pouch that can be inserted into a rigid container. By utilizing the effect of reducing the surface area due to the contraction of the elastic pouch and the pressure exerted by the elasticity (resilience) of the elastic pouch to push the contents toward the opening and the discharge pressure of the discharge device, the remaining contents can be effectively made usable. When the elastic pouch expands due to the elasticity it has, the rigid container can be deformed into various forms, providing the effect of enabling the design of the container without being restricted by the form of the rigid container.

[0055] The pouch unit, container device, and content filling device according to an embodiment of the present invention can hygienically and efficiently fill the elastic pouch with contents while satisfying the condition that the elastic pouch must be expanded by the size of the outer container in order to inject the contents.

[0056] Also, by using the pouch unit according to the disclosed embodiment of the present invention, the liquid contents can be easily filled without physically stretching the pouch unit by sliding the nozzle part as in the conventional method. Therefore, there is an advantage of preventing damage to the pouch unit during the process of filling the pouch unit.

[0057] Also, by using the pouch unit according to the disclosed embodiment of the present invention, the area of contact with the inner surface of the outer container is reduced by at least one pouch unit body recess during the process of the pouch unit expanding. Thus, the frictional force generated during the process of the pouch unit body expanding due to the filling of the liquid contents is reduced, and there is an advantage that the liquid contents can be easily filled.

[0058] Also, by using the container device according to the disclosed embodiment of the present invention, the filling space of the pouch unit is selectively communicated according to the shape of the selective seal unit, minimizing the contamination of the contents and enabling the easy filling of the contents.

[0059] Furthermore, by using the content filling device according to the disclosed embodiments of the present invention, it is possible to seal the internal space of the seal unit to form a pressure that facilitates the injection of liquid contents, and there is an advantage that the liquid contents can be stably and easily filled into the filling space.

DETAILED DESCRIPTION OF THE INVENTION

[0061] The advantages, features, and methods for achieving them of the present invention will become clear by referring to the embodiments described in detail below together with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, and can be realized in various different forms. Merely, these embodiments are provided so that the disclosure of the present invention is complete, and to fully inform those with ordinary knowledge in the technical field to which the present invention pertains of the scope of the invention. The present invention is defined only by the scope of the claims.

[0062] For example, although first, second, etc. are used to describe various components, it goes without saying that these components are not limited by these terms. These terms are merely used to distinguish one component from another. Therefore, it goes without saying that the first component mentioned below may be the second component within the technical idea of the present invention.

[0063] The same reference numerals throughout the specification refer to the same components.

[0064] The features of each of the various embodiments of the present invention can be partially or wholly combined or combined with each other, and various technical linkages and drives are possible as fully understood by those skilled in the art. Each embodiment may be implemented independently of each other or may be implemented together in relevant relationships.

[0065] On the other hand, the provisional effects that can be expected from the technical features of the present invention not specifically mentioned in the description of the present invention are handled as described in this specification. This embodiment is provided to more fully explain the present invention to those with average knowledge in the industry. However, the content shown in the drawings is exaggerated compared to the actual implementation mode of the invention, and detailed descriptions of configurations that may unnecessarily obscure the gist of the present invention are omitted or briefly described.

[0066] In this specification, "liquid" generally refers to a wide range of liquid states that are not in a solid or gaseous state. That is, it means all states where the intermolecular distance is short and the kinetic energy is low, but the molecules are not strongly attached like in the solid state, and it is used in the sense of including all liquids without viscosity like water to highly viscous liquids like gels.

[0067] In this specification, "elastic pouch" generally refers to a pouch that has a fixed appearance as a soft bag, or may not have a fixed appearance, and has a restoring force to return to its original shape when it stretches or expands elastically while its shape changes under an external force, or a pouch that does not have a fixed appearance as a simple soft bag and whose shape changes under an external force.

[0068] In this specification, "container" means all types of containers having a hard material with a certain outer shape such as plastic, glass, metal, paper, etc., and is used interchangeably with "rigid container" or "hard container".

[0069] Hereinafter, with reference to the attached drawings, embodiments of the present invention will be described in detail so that those having ordinary knowledge in the technical field to which the present invention pertains can easily implement them. The present invention can be realized in various different forms and is not limited to the embodiments described herein. In the drawings, parts not related to the description are omitted in order to clearly explain the present invention, and the same or similar components throughout the specification are denoted by the same reference numerals. Also, the sizes and thicknesses of the respective configurations shown in the drawings are arbitrarily shown for convenience of explanation, and the present invention is not necessarily limited to the illustration.

[0070] FIG. 3 is a view showing a pouch unit 100 according to the disclosed embodiment of the present invention, FIG. 4 is a view showing the outer peripheral surface of the pouch unit 100 according to the disclosed embodiment of the present invention, and FIG. 5 is a view showing the bottom surface of the pouch unit 100 according to the disclosed embodiment of the present invention.

[0071] Referring to FIGS. 3 to 5, the pouch unit 100 according to the disclosed embodiment of the present invention is formed of an elastic material including at least one of known materials such as rubber, PVC, and urethane, and a filling space 120 for filling liquid is formed inside. A liquid content can be injected and filled into the filling space 120 of the pouch unit 100, and the liquid content accommodated inside the pouch unit 100 is pumped by a pump unit (not shown) and discharged to the outside, and has a feature that the liquid content does not remain on the inner wall surface of the container device 1 in the process of using the container device 1 described later.

[0072] The pouch unit 100 can include a pouch unit body 110 formed of an elastic material and capable of expanding or contracting by a predetermined external force. As an example, among the pouch unit 100, the pouch unit body 110 can expand by a predetermined external force. More specifically, at least a part of the pouch unit 100 is accommodated in a rigid external container (for example, reference numeral 200 in FIG. 8), and at least a part of the pouch unit 100 accommodated in the external container can include the pouch unit body 110. The pouch unit body 110 expands due to the pressure generated by filling with the liquid content, and in particular, the vertical expansion speed and the horizontal expansion speed can be adjusted according to the tensile strength and elongation rate formed by the height and thickness of the pouch unit body convex portion 112 formed on the pouch unit body 110.

[0073] Similarly, when the filling space 120 of the pouch unit 100 is filled with the liquid content and the pouch unit 100, the external container, and the pump unit (for example, reference numeral 30 in FIG. 1A) are interconnected and distributed and sold as a finished product, the user can discharge and use the liquid content filled in the filling space 120 of the pouch unit 100 through the pump unit, and the pressure applied by the liquid content to the pouch unit body 110 decreases. As a result, the pouch unit body 110 contracts. Through such a discharging process, the volume of the filling space 120 decreases, and there is an advantage that the remaining liquid content filled in the filling space 120 can be minimized while enabling the hygienic use of the content.

[0074] In the prior art, there have been attempts to apply a soft pouch unit 100 as described above to minimize the remaining liquid content. However, in the process of filling the pouch unit 100 with the liquid content, the pouch unit body 110 expands and contacts the inner surface of the rigid external container 200. Due to the characteristics of the pouch unit 100 formed of a highly elastic and high-friction material, after a part of the pouch unit 100 contacts the inner surface of the external container 200, there is a problem that it is difficult for the pouch unit 100 to expand so as to sufficiently occupy the internal volume of the external container 200.

[0075] In particular, due to such problems, the liquid content may not be easily filled into the filling space 120 of the pouch unit 100, and the risk of flowing out to the outside may increase. Also, due to the friction between the pouch unit 100 and the external container 200, the risk of damage to the pouch unit 100 may increase.

[0076] To solve such problems, the pouch unit 100 according to the disclosed embodiments of the present invention can include at least one pouch unit body recess 111 in the pouch unit body 110. The at least one pouch unit body recess 111 can extend in at least one direction by the extension of the pouch unit body 110. As an example, the pouch unit body recess 111 is formed to extend along the longitudinal direction (for example, the vertical direction) of the pouch unit body 110. The pouch unit body recess 111 is formed to be recessed inward from the outer peripheral surface of the outermost contour of the pouch unit body 110 to a predetermined depth.

[0077] To correspond to the pouch unit body recess 111, the pouch unit body 110 of the pouch unit 100 can include at least one pouch unit body protrusion 112. At this time, at least one pouch unit body recess 111 is formed adjacent to at least one pouch unit body protrusion 112. By forming at least one pouch unit body recess 111 and at least one pouch unit body protrusion 112 adjacent to each other, a flow path through which the air remaining inside the external container 200 described later can be discharged to the outside can be formed. More specifically, the pouch unit body recess 111 and the pouch unit body protrusion 112 are alternately arranged along the periphery of the pouch unit body 110 and are formed such that the concave and convex shape (or serrated shape) is continuous. By forming the pouch unit body recess 111 and the pouch unit body protrusion 112 alternately arranged with each other so that the concave and convex shape is continuous, when the liquid content is filled in the filling space 120, the air remaining inside the external container 200 can be discharged to the outside through the flow path formed by the concave and convex shape without separately removing it. As a result, there is an advantage that the pouch unit 100 made of an elastic material can easily expand inside the rigid external container 200.

[0078] More specifically, as the liquid content is filled into the filling space 120 of the pouch unit 100, the pouch unit body 110 expands. When the pouch unit body 110 expands, at least one pouch unit body recess 111 and at least one pouch unit body protrusion 112 formed on the outer peripheral surface of the pouch unit body 110 also expand, and at least one pouch unit body protrusion 112 can contact the inner surface of the external container. However, even when at least one pouch unit body protrusion 112 contacts the inner surface of the external container, at least one pouch unit body recess 111 can maintain a state of being separated from the inner surface of the external container. That is, by separating at least one pouch unit body recess 111 from the inner surface of the external container 200, the area where the pouch unit body 110 contacts the inner surface of the external container 200 can be reduced. As a result, the liquid content is filled into the filling space 120 corresponding to the internal shape of the external container 200, and until the pouch unit body 110 expands sufficiently, it has a reduced frictional force compared to the prior art, so that the filling of the liquid content can be easily performed, and the time required to fill the content can also be shortened. Further, due to the symmetrical and repeated structure of the flow path (at least one flow path portion 142 described later) formed by the alternating arrangement of at least one pouch unit body recess 111 and at least one pouch unit body protrusion 112, the pouch unit 100 can expand uniformly and minimize the asymmetric expansion that may occur due to the thickness deviation of the pouch unit 100 caused by the eccentricity of the mold, which has the advantage of enabling the liquid content to be easily filled into the expanded pouch unit 100.

[0079] On the other hand, the width of at least one pouch unit body recess 111 is formed wider than the width of at least one pouch unit body protrusion 112. Thereby, even when the pouch unit 100 expands due to the filling of the liquid content, the deformation of the pouch unit body protrusion 112 is minimized, and a flow path through which the air remaining inside the external container 200 can be easily discharged to the outside can be stably maintained.

[0080] Hereinafter, the detailed configuration of the pouch unit body recess 111 will be described.

[0081] Referring to FIGS. 3 to 5 (particularly FIGS. 4 and 5), a one-end portion 113 of the pouch unit body 110 is formed at one end of the pouch unit body 110. The one-end portion 113 of the pouch unit body is configured such that the pouch unit body 110 has a shape (e.g., a U-shape) that can be inflated by a uniform pressure, and a filling space 120 is formed by the one-end portion 113 of the pouch unit body. The one-end portion 113 of the pouch unit body is formed to face a pouch-side opening 130 that communicates with the filling space 112, and the one-end portion 113 of the pouch unit body can contact the inner surface of the bottom surface of the external container when the liquid content is filled.

[0082] On the other hand, at least one pouch unit body recess 111 can include a first pouch unit body recess 111a and a second pouch unit body recess 111b.

[0083] As an example, the first pouch unit body recess 111a may be a portion that has a constant recessed circumference and extends in the vertical direction. At this time, the "recessed circumference" can mean the circumferential length (e.g., the arc length) of the first pouch unit body recess 111a. By forming the first pouch unit body recess 111a having a constant recessed circumference in the cylindrical-shaped portion of the pouch unit body 110, the pouch unit body 110 can be easily expanded and contracted in the vertical direction.

[0084] Further, the second pouch unit body recess 111b is continuously formed from one end of the aforementioned first pouch unit body recess 111a, and is formed such that the perimeter of its depression gradually decreases toward one end 113 of the pouch unit body. More specifically, the second pouch unit body recess 111b can have a tapered shape in which the width of the perimeter of the depression decreases as it goes toward the end (i.e., one end of the pouch unit body formed at the lower part of the pouch unit body) of the pouch unit body 110. Thereby, one end 113 of the pouch unit body can easily adhere to the bottom surface of the outer container 200, and the pouch unit body recess 111 has the advantage of forming a structure in which the pouch unit body 110 can easily expand and contract.

[0085] However, the structure in which the perimeter of the depression of the second pouch unit body recess 111b is formed to gradually decrease toward one end 113 of the pouch unit body is exemplary, and if necessary, the perimeter of the depression of the second pouch unit body recess 111b may form a structure in which the width of the pouch unit body convex portion 112 decreases while being kept constant. When such a structure is formed, there is an advantage that the flow path formed by the pouch unit body recess 111 is stably maintained even when the pouch unit 100 is filled with a liquid content and the pouch unit 100 expands.

[0086] Hereinafter, the detailed configuration of the pouch unit 100 that enables the liquid content to be more easily filled into the filling space 120 of the pouch unit 100 will be described.

[0087] The pouch unit 100 may include a pouch side locking portion 140 together with the pouch unit body 110. The pouch side locking portion 140 is locked and coupled to an upper portion of the outer container 200 (e.g., the central upper end surface of the outer container) and may play a role of supporting the entire pouch unit 100 so as not to be rolled up inside the outer container 200. In addition, as described below, a selective seal unit 300 that supports the pouch side locking portion 140 so as not to be rolled up inside the outer container 200 may be additionally considered, and the pouch unit 100 may be designed to reduce the number of at least one flow passage portion 142 formed.

[0088] For example, the pouch side locking portion 140 is formed integrally with the pouch unit body 110 and is formed to extend a predetermined length from the pouch unit body 110 in the radial direction. The pouch side locking part 140 may include a pouch side locking part body 141, which is formed to protrude a predetermined thickness in the up-down direction. The pouch side locking part 140 is formed of the same material as the pouch unit body 110. The pouch side locking part body 141 is formed to a certain thickness or more to prevent the entire pouch unit 100 from being accommodated inside the outer container 200 during the process of filling the filling space 120 with liquid contents. Since the pouch side locking part body 141 is formed to a certain thickness or more, it is possible to prevent the pouch side locking part 140 placed on the upper part of the outer container 200 from being accommodated in an accommodation space (reference numeral 211 in FIG. 8) formed inside the outer container 200.

[0089] Further, the pouch side locking portion 140 may include at least one flow path portion 142. For example, the at least one flow path portion 142 is recessed to a predetermined depth in an inward direction on the outer circumferential surface of the pouch side locking portion 140. More specifically, the at least one flow path portion 142 may communicate the inside of the outer container 200 (i.e., a storage space formed inside the outer container) with the outside.

[0090] More specifically, the cross-section of at least one flow path portion 142 is formed in an arch shape. As an example, the cross-section of at least one flow path portion 142 can have a semi-circular shape, but is not necessarily limited thereto. Further, at least one flow path portion 142 is formed adjacent to at least one support portion 143. That is, at least one support portion 143 is disposed on both sides of at least one flow path portion 142 in the pouch side locking portion 140. Substantially, a plurality of flow path portions 142 and a plurality of support portions 143 are alternately formed on the outer peripheral surface of the pouch side locking portion 140.

[0091] Since the cross-section of at least one flow path portion 142 is formed in an arch shape, there is an advantage that the pressure applied from the selective seal unit 300 and the content filling device 500, which will be described later, can be effectively dispersed and supported. Further, there is an advantage that the pressure applied from above to below of at least one flow path portion 142 by at least one support portion 143 can be effectively dispersed and supported.

[0092] On the one hand, the characteristic shape of such a pouch-side locking portion 140 is associated with the characteristic shape of the pouch unit body 110. As an example, at least a part of at least one flow path portion 142 of the pouch-side locking portion 140 is continuously formed with at least one pouch unit body recess 111 of the pouch unit body 110. More specifically, the outer end (the portion separated from the pouch unit body) of at least one flow path portion 142 is connected to the outside, and the inner end (the portion connected to the pouch unit body) of at least one flow path portion 142 is connected to the upper end of the first pouch unit body recess 111a among the pouch unit body recesses 111 and is continuously formed. In this way, by interconnecting at least one flow path portion 142 and at least one pouch unit body recess 111 to form a continuous structure, at least one decompression flow path for communicating the inside and the outside of the external container 200 can be formed. Due to at least one decompression flow path formed by at least one flow path portion 142 and at least one pouch unit body recess 111, the air remaining in the accommodation space 211 between the external container 200 and the pouch unit 100 is easily discharged by the expansion of the pouch unit body 110, and there is an advantage that the pouch unit body 110 can accommodate the liquid content to the maximum corresponding to the shape of the external container 200.

[0093] Also, the width of the pouch unit body recess 111 is formed wider than the width of the pouch unit body convex portion 112. Thereby, even when the pouch unit 100 expands due to the filling of the liquid content, the deformation of the pouch unit body convex portion 112 is minimized, and a flow path through which the air remaining inside the external container 200 can be easily discharged to the outside can be stably maintained.

[0094] Similarly, the width of at least one flow path portion 142 is formed wider than the width of at least one support portion 143. Thereby, even when the pouch unit 100 expands due to the filling of the liquid content, the deformation of the support portion 143 is minimized, and a flow path through which the air remaining inside the external container 200 can be easily discharged to the outside can be stably maintained.

[0095] On the other hand, in the prior art, the air remaining in the accommodation space 211 of the external container 200 was discharged to the outside through a decompression unit provided separately from the container device. In contrast, the container device according to the disclosed embodiment of the present invention can easily discharge the air remaining in the accommodation space 211 without using another decompression unit, whereby the pouch unit body 110 can accommodate the liquid content to the maximum corresponding to the shape of the external container 200.

[0096] Hereinafter, the pouch unit 100' according to another disclosed embodiment of the present invention will be described.

[0097] FIG. 6 is a view showing the pouch unit 100' according to another disclosed embodiment of the present invention, and FIG. 7 is a view showing the outer peripheral surface of the pouch unit 100' according to another disclosed embodiment of the present invention.

[0098] Referring to FIGS. 6 and 7, the pouch unit 100' according to another disclosed embodiment of the present invention can include a pouch unit body 110' and a filling space 120. The pouch unit body 110' can have at least one pouch unit body recess 111' and at least one pouch unit body protrusion 112.

[0099] However, in the above-described embodiment, at least one pouch unit body recess 111 and / or at least one pouch unit body protrusion 112 extend in the vertical direction and are continuously formed with at least one flow path portion 142 and at least one support portion 143 of the pouch side locking portion 140.

[0100] In contrast, in this embodiment, at least a portion of at least one pouch unit body recess 111' may be formed continuously with at least one flow path portion 142 to form a flow path. First, in a pouch unit body 110', which is one configuration of a pouch unit 100' according to another embodiment of the present invention, a pouch unit body one end portion 113' is formed at one end of the pouch unit body 110', and a pouch unit body other end portion 114 is formed at the other end of the pouch unit body 110'.

[0101] The pouch unit body other end portion 114 is formed adjacent to the pouch side locking portion 140. In addition, the outer peripheral surface of the pouch unit body other end portion 114 may correspond to the outer peripheral surface of at least one pouch unit body protrusion portion 112. That is, when the pouch unit 100' expands, the outer peripheral surface of the other end 114 of the pouch unit body comes into surface contact with the inner wall surface of the outer container 200 to provide friction. This has the advantage that the pouch unit 100' is prevented from being rolled up inside the outer container 200 even when the pouch unit 100' is filled with liquid contents and expands.

[0102] Furthermore, at least one pouch unit body recess 111' may include a first pouch unit body recess 111a and a third pouch unit body recess 111c. The first pouch unit body recess 111a has a certain recessed circumference and is formed to extend in the up-down direction. At this time, the third pouch unit body recess 111c is formed on one side of the first pouch unit body recess 111a, has a certain recessed circumference, and is formed to extend in the vertical direction so as to have a length shorter than the vertical extension length of the first pouch unit body recess 111a. That is, the first pouch unit body recess 111a and the third pouch unit body recess 111c are formed in parallel, but the first pouch unit body recess 111a may have a length longer than the third pouch unit body recess 111c.

[0103] Due to the distinct structures of the first pouch unit body recess 111a and the third pouch unit body recess 111c, a pouch unit body other end 114 is formed having an outer peripheral surface corresponding to the outer peripheral surface of the pouch unit body protrusion 112. In particular, the pouch unit body other end 114 can provide frictional force by surface contact with an inner wall surface of a neck portion 220 of an outer container 200 of a container device 1 described later, which has the advantage of preventing the pouch unit 100' from being rolled up inside the outer container 200 even if the pouch unit 100' is filled with liquid contents and expands.

[0104] More specifically, the first pouch unit body recess 111a is formed integrally with the pouch unit body 110' and is formed extending a predetermined length in the radial direction from the pouch unit body 110' to be formed between the pouch side locking part 140 disposed on the upper part of the outer container 200 and one end part 113' of the pouch unit body. As a result, the first pouch unit body recess 111a is formed continuously with at least one flow path part 142 recessed to a predetermined depth in the inward direction on the outer circumferential surface of the pouch side locking part 140, thereby forming a flow path that communicates the inside and outside of the outer container 200.

[0105] In contrast, the third pouch unit body recess 111c is formed between the pouch unit body one end 113' and the pouch unit body other end 114. Therefore, the air in the outer container 200 is easily discharged to the outside through the first pouch unit body recess 111a, the third pouch unit body recess 111c reduces the contact area between the pouch unit 100' and the outer container 200, reducing the frictional force generated between the pouch unit 100' and the inner surface of the outer container 200, making it easy to fill with liquid contents, and the pouch unit body other end 114 prevents the pouch unit 100' from being caught inside the outer container 200.

[0106] Hereinafter, the pouch unit 100' according to still other disclosed embodiments of the present invention will be described. However, since the characteristic contents of the pouch unit according to still other disclosed embodiments of the present invention are shown together in FIGS. 6 and 7, the characteristic contents will be described with reference to FIGS. 6 and 7.

[0107] Referring to FIGS. 6 and 7, in the pouch unit 100' according to still other disclosed embodiments of the present invention, the outer peripheral surface of one end portion 113' of the pouch unit body does not have an uneven shape. More specifically, one end portion 113' of the pouch unit body does not include the second pouch unit body recess 111b. Since one end portion 113 of the pouch unit body does not have an uneven shape, when the pouch unit 100' is filled with a liquid content and the pouch unit 100' expands, one end portion 113' of the pouch unit body can expand uniformly in the whole direction, which has the advantage.

[0108] Also, the outer peripheral surface of one end portion 113' of the pouch unit body can correspond to the outer peripheral surface of at least one pouch unit body recess 111'. More specifically, the outer surface of one end portion 113' of the pouch unit body and the outer surface of at least one pouch unit body recess 111' are continuously formed. At this time, the pouch unit body convex portion 112 can have a shape protruding radially from the outer surface of the pouch unit body recess 111'. Since the outer peripheral surface of one end portion 113 of the pouch unit body corresponds to the outer peripheral surface of at least one pouch unit body recess 111', one end portion 113' of the pouch unit body has the advantage of being able to expand more easily and uniformly.

[0109] According to the above description, the pouch units 100, 100' have been described with respect to embodiments that additionally include the other end portion 114 of the pouch unit body and one end portion 113' of the pouch unit body that does not have the second pouch unit body recess 111b. However, such description is illustrative, and it must be understood that a pouch unit that simultaneously has one end portion 113' of the pouch unit body that does not have the second pouch unit body recess 111b and the other end portion 114 of the pouch unit body is also included within the scope of the rights of the present invention.

[0110] Hereinafter, the container device 1 according to the disclosed embodiments of the present invention will be described. In describing the container device 1 according to the disclosed embodiments of the present invention, the content overlapping with the above-described pouch unit 100 will be briefly described or the description thereof will be omitted.

[0111] Also, since the above-described pouch unit includes various embodiments, in the following description, for convenience, it must be understood that the pouch unit indicated by the reference numeral 100 also includes other embodiments.

[0112] FIG. 8 is a diagram for explaining a container device according to a disclosed embodiment of the present invention, FIG. 9 is an example of a selective seal unit which is a configuration of a container device according to a disclosed embodiment of the present invention, and FIG. 10 is a cross-sectional view in which a pouch unit and the selective seal unit 300, which are configurations of a container device according to a disclosed embodiment of the present invention, are combined.

[0113] Referring to FIGS. 8 to 10, the container device 1 according to the disclosed embodiments of the present invention can include the above-described pouch unit 100, an external container 200, and a selective seal unit 300.

[0114] The outer container 200 has an accommodation space 211 formed therein, and the pouch unit 100 is coupled to the outer container 200, and a part of the pouch unit 100 is inserted into the accommodation space 211. The filling space 120 formed by the pouch unit body 110 which is a configuration of the pouch unit 100 is filled with a liquid content. That is, the liquid content is not filled in the accommodation space 211 of the outer container 200, but is filled in the filling space 120 of the pouch unit 100, so that the liquid content does not remain on the inner wall surface of the outer container 200 during the use process, and the user can use the liquid content with a maximum of no residue. Also, by reducing the volume of the filling space 120 of the pouch unit 100 during the discharge process of the liquid content, the residue of the liquid content can be suppressed to the maximum extent.

[0115] The outer container 200 includes an outer container body 210 in which an accommodation space 211 is formed therein, and a neck portion 220 disposed above the outer container body 210, having a diameter smaller than the diameter of the outer container body 210, and having an opening communicating with the accommodation space 211 on the upper surface. As an example, the outer container 200 is formed of a material having a certain strength of a certain size for maintaining the outer shape, such as plastic, metal, paper or glass. On the other hand, a configuration in which the outer container 200 is formed in a cylinder shape without being divided into the neck portion 220 and the outer container body 210 is also included in the embodiments of the present invention.

[0116] In this embodiment, the accommodation space 211 of the outer container 200 communicates with the outside through the opening of the neck portion 220, and a communication structure with the outside can be formed through a flow path formed by at least one pouch unit body recess 111 and at least one flow path portion 142 of the pouch unit 100 described above. However, if necessary, a configuration in which other through holes or a plurality of voids are formed in the outer container body 210 of the outer container 200 in addition to the opening is also included in the embodiments of the present invention.

[0117] The pouch unit 100 accommodates liquid contents while being coupled to the external container 200. As described above, the pouch unit 100 is formed of an elastic material, and includes a pouch unit body 110 formed of an elastic material and having a filling space 120 formed therein for filling with liquid, and a pouch-side locking portion 140 for preventing the pouch unit 100 from being entirely accommodated inside the external container 200.

[0118] The pouch unit 100 is, for example, formed of an elastic material, an extensible material, and is formed of, for example, silicone, natural or synthetic latex rubber, or a polymer substance. Further, the pouch unit 100 can include at least one pouch unit body recess 111 and at least one pouch unit body protrusion 112 on the outer peripheral surface of the pouch unit body 110, and can include at least one flow path portion 142 and at least one support portion 143 in the pouch-side locking portion 140. Since the detailed structure of the pouch unit 100 is the same as the above-described content, detailed description is omitted, and it should be understood that the container device 1 according to the disclosed embodiment of the present invention includes all the characteristic contents of the pouch unit 100 according to the disclosed embodiment of the present invention.

[0119] Hereinafter, a selective seal unit 300, which is a configuration of the container device 1 according to the disclosed embodiment of the present invention, will be described.

[0120] A selective seal unit 300, which is a configuration of the container device 1 according to the disclosed embodiment of the present invention, is formed to be coupled to the upper portion of the pouch unit 100. By the selective seal unit 300 being formed to be coupled to the upper portion of the pouch unit 100, the selective seal unit 300 can serve to selectively communicate the filling space 120 of the pouch unit 100 with the outside.

[0121] That is, the selective seal unit 300 separates the filling space 120 of the pouch unit 100 from the outside when no external force or pressure acts from the outside, and communicates the filling space 120 of the pouch unit 100 with the outside when a specific external force or pressure acts from the outside, enabling the filling space 120 to be filled with a liquid content or allowing the liquid content accommodated in the filling space 120 to be discharged to the outside.

[0122] When the pouch unit 100 is filled with a liquid content and the pouch unit 100 expands, the pouch unit 100 can have a contracting force due to the elastic restoring force. The selective seal unit 300 coupled to the upper part of the pouch unit 100 can also be affected by the contracting force of the pouch unit 100. When the selective seal unit 300 contracts together due to the contracting force of the pouch unit 100, there is a risk that the sealed state of the filling space 120 of the pouch unit 100 will be released. If the sealed state of the filling space 120 is released, there is a risk that the liquid content cannot be stably accommodated. Therefore, the hardness of the selective seal unit 300 is formed to be greater than the hardness of the pouch unit 100 described above.

[0123] The selective seal unit 300 is partially opened around a slit so that one end of a nozzle part (or one end of an extended nozzle part), which is a detailed configuration of a content filling device 500 described later, can be inserted, or one end of a discharge pipe of a discharge part (not shown) can be inserted to fill or discharge the liquid content. However, when the hardness of the selective seal unit 300 is excessively large, the slit will not be opened by the insertion of the content filling device 500 or the insertion of the discharge part. Therefore, the selective seal unit 300 must have a hardness such that the slit can be opened by an external force while maintaining the properties of an elastic body, and preferably has a hardness of 72 SHORE A or more and 85 SHORE A or less.

[0124] The detailed components of the selective seal unit will be described below. The selective seal unit 300 can include a seal unit support portion 310. As an example, at least a part of the upper portion of the pouch side locking portion 140 on which the pouch unit 100 is placed and supported on the upper portion of the outer container 200 can be in surface contact with the seal unit support portion 310. More specifically, the bottom surface of the seal unit support portion 310 is in surface contact with the upper surface of the pouch side locking portion 140, so that the liquid content filled in the filling space 120 of the pouch unit 100 can be sealed in the filling space without flowing out to the outside. Further, a flat stepped portion 310a protruding downward by a predetermined thickness is formed on the bottom surface of the seal unit support portion 310. The flat stepped portion 310a enables the seal unit support portion 310 to be stably adhered to the pouch side locking portion 140.

[0125] Further, the selective seal unit 300 can include a seal unit body 320. The seal unit body 320 extends downward from the inner peripheral surface of the seal unit support portion 310. The seal unit body 320 extends by a predetermined length toward the pouch unit body 110 side of the pouch unit 100. More specifically, the seal unit body 320 may have a cylindrical shape or may have a dome shape with a bulged lower portion. Further, the seal unit body 320 may have a tapered shape in which the outer diameter and / or the inner diameter gradually decrease in the downward direction from the seal unit support portion 310. Depending on the shapes of the seal unit support portion 310 and the seal unit body 320, the filling space 120 of the pouch unit 100 can be separated from the outside.

[0126] In some embodiments, a side stepped portion (not shown) that protrudes outward by a predetermined thickness is formed on a part of the outer peripheral surface of the seal unit body 320. As an example, the side stepped portion can contact a part of the inner surface of the pouch unit body 110 of the pouch unit 100. More specifically, the side stepped portion contacts the inner surface of the pouch unit body 110 at a portion adjacent to the pouch side opening 130 of the pouch unit body 110, thereby forming a structure in which the pouch unit 100 and the selective seal unit 300 are stably coupled.

[0127] Also, in the selective seal unit 300, a slit 331 that is selectively opened and closed by the pressurization of the content filling device 500 is formed in the central portion of the seal unit body 320. As an example, the slit 331 is formed in a shape extending in one direction from the center of the selective seal unit 300. The slit 331 is opened by a certain area by the pressurization of the content filling device 500, and the liquid content is injected and filled into the filling space 120 through the slit 331. At this time, the content supply means 910 is connected to the content filling device 500, and the liquid content is injected and filled into the filling space 120 by the opening and closing operation of the valve unit 941. Also, in the completed product, the slit 331 may be opened by the pumping operation of a pump unit (not shown) of the discharge part, and the liquid content stored in the filling space 120 may be discharged to the outside.

[0128] In some embodiments, the selective seal unit 300 can further include a seal unit extension portion 330 that is formed integrally with the seal unit body 320 while extending downward by a predetermined length from the seal unit body. Substantially, the slit 331 is formed in at least a partial region at the lower part of the seal unit extension portion 330. Such a structure has the advantage that the liquid content can be more easily guided into the filling space 120.

[0129] In some embodiments, the selective seal unit 300 may further include a seal unit cover portion that extends downward from the outer peripheral surface of the lower end of the seal unit body 320 by a predetermined length. As an example, the seal unit cover portion can physically protect (cover) the central portion of the seal unit body 320 from the external environment. The seal unit cover portion can prevent the inner surface of the pouch unit body 110 of the pouch unit 100 from contacting the slit 331 or the seal unit extension portion 330 formed at the central portion of the seal unit body 320 and interfering with the smooth filling of the liquid content.

[0130] On the other hand, in the container device 1 according to the disclosed embodiments of the present invention, the selective seal unit 300 may further include a seal unit internal space 340 that can accommodate the nozzle cover portion 522 of the content filling device 500 described later or the engine portion (pump engine portion) of the discharge portion 30 described above. Further, the selective seal unit 300 is formed such that at least a part of the lower end of the seal unit extension portion 330 that constitutes the slit 331 can be in mutual correspondence and adhere tightly so that the slit 331 can be closed when a shrinkage pressure is applied to the pouch unit 100.

[0131] Also, the seal unit extension portion 330 may include a cross-sectional portion 332. The cross-sectional portion 332 enables the seal unit extension portion 330 of the selective seal unit 300 to easily receive pressure so that the slit 331 can be closed more firmly.

[0132] Furthermore, when the discharge unit 30 is coupled, in order to prevent the problem that the engine of the discharge unit 30 cannot extend the selective seal unit 300 to open the slit 331, and to enable the engine of the discharge unit 30 to be easily guided to the slit 331 to open the slit, the seal unit extension 330 can further include a nozzle guide portion 333 on its inner surface. The nozzle guide portion 333 can have a shape bent so that the inclination increases toward the lower direction. The nozzle guide portion 333 is formed to have an angle of 45° or less with respect to the vertical line so that the nozzle portion 510 or the discharge pipe can be easily guided.

[0133] Thus, by using the selective seal unit 300 including various shapes of the present invention, the liquid content can be easily filled into the filling space 120 of the pouch unit 100, and the filling space 120 can be maintained in a sealed state, so that there is an advantage that contamination of the liquid content can be prevented.

[0134] Hereinafter, the content filling device 500 according to the disclosed embodiment of the present invention for filling the container device 1 with (liquid) content will be described.

[0135] FIG. 11 is a diagram for explaining the content filling device 500 and the container device 1 for filling the pouch unit 100 of the container device 1 according to the disclosed embodiment of the present invention.

[0136] Referring to FIGS. 1 to 11, the content filling device 500 according to the disclosed embodiment of the present invention is a device for filling the container device 1 with content. More specifically, the content filling device 500 corresponds to a device for filling a container device 1 including a pouch unit 100 formed of an elastic material and having a filling space 120 for filling liquid therein, and a selective seal unit 300 coupled to the upper part of the pouch unit 100 and selectively communicating the filling space 120 of the pouch unit 100 with the outside.

[0137] The content filling device 500 can include a nozzle part 510 that injects the content into the filling space 120 of the pouch unit 100. One end part 511 of the nozzle part 510 is formed to protrude in one direction so as to be inserted into the container device 1 side, and the other end part (not shown) of the nozzle part 510 is connected to the content supply means 910 via the valve unit 941. The content supply means 910 can supply the liquid content to the nozzle part 510 at a constant pressure corresponding to the opened degree of the valve unit 941, and the nozzle part 510 can supply the liquid content to the filling space 120 of the pouch unit 100 of the container device 1 through its one end part 511.

By the seal block part 520 sealing the seal unit internal space 340, the pouch unit 100 can be stably extended by the supply of the liquid content through the nozzle part 510, and the liquid content can be easily filled.

[0139] The content filling device 500 according to the disclosed embodiment of the present invention can include a device connection part 530. The device connection part 530 enables the nozzle part 510, the seal block part 520, and the device upper end part 540 to be stably connected. Also, the size of the inner peripheral surface of the device connection part 530 can be adjusted by a first fastening means which is a kind of fastening means 550 coupled to one side. As a result, there is an advantage that nozzles 510 and seal block parts 520 of various specifications can be applied.

[0140] Packing units are respectively accommodated in the upper and lower parts of the device connection part. The packing unit can cover a part of the outer peripheral surface of the nozzle part 510 to stably support the nozzle part 510.

[0141] Also, the content filling device 500 according to the disclosed embodiment of the present invention is assembled by fastening means 550. As an example, through a first fastening means horizontally coupled to the device connection part 530 and at least one second fastening means vertically coupled to the seal block part 520, the device connection part 530, and the upper end part 540 of the device, the content filling device 500 can form a strong coupling structure.

[0142] Hereinafter, the detailed configuration of the seal block part 520 will be described in more detail.

[0143] FIG. 12A is a diagram for explaining the process in which the content filling device 500 according to the disclosed embodiment of the present invention moves toward the container device 1, and FIG. 12B is a cross-sectional view of FIG. 12A. Further, FIG. 13A is a diagram for explaining the state in which the content filling device 500 according to the disclosed embodiment of the present invention is in close contact with the container device 1, and FIG. 13B is a cross-sectional view of FIG. 13A.

[0144] Referring to FIGS. 11, 12A, and 12B, in the content filling device 500 according to the disclosed embodiments of the present invention, the seal block portion 520 can include a seal block support portion 521. As an example, the seal block support portion 521 can be in line contact or surface contact with at least a part of the upper portion of the seal unit support portion 310 where the upper portion of the pouch side locking portion 140 on which the pouch unit 100 is placed and supported on the upper portion (for example, the neck portion of the outer container) of the outer container 200 is in surface contact. For example, the seal block support portion 521 is formed in a flat ring shape, and the seal block support portion 521 can be in surface contact with the seal unit support portion 310. As another example, the seal block support portion 521 is formed in a tapered shape, and in this case, the seal block support portion 521 can be in line contact with the seal unit support portion 310. In the attached drawings of the present invention, the seal block support portion 521 is shown as having a flat ring shape, but it is not necessarily limited thereto, and it can also be formed in a tapered shape as described above.

[0145] Also, the seal block portion 520 can include a nozzle cover portion 522. The nozzle cover portion 522 can be designed to have a shape corresponding to the seal unit internal space 340. By designing the nozzle cover portion 522 to correspond to the shape of the seal unit internal space 340, when the content is filled through the nozzle, when the seal unit internal space 340 is filled by the nozzle cover portion 522 and the content filling is completed, it is possible to minimize the attachment or filling of the liquid content in the seal unit internal space 340. The nozzle portion 510 can be formed only up to the nozzle cover portion 522, or can be extended and formed below the nozzle cover portion 522. When the nozzle portion 510 extends below the nozzle cover portion 522, when the nozzle cover portion 522 is accommodated in the seal unit internal space 340 for content filling, one end portion 511 of the nozzle portion 510 can open the slit 331.

[0146] Further, the seal block portion 520 can include a nozzle housing portion 513. The nozzle housing portion 513 can mean a portion that opens with a certain area from the radial center of the seal block portion 520, and the nozzle portion 510 can penetrate the nozzle housing portion 513 from the upper part to the lower part.

[0147] Referring to FIGS. 12A and 12B, the content filling device 500 can move downward toward the container device 1. At this time, the outer container 200 of the container device 1 may be in a state where the pouch unit body 110 of the pouch unit 100 is accommodated in the accommodation space 211. Further, a selective seal unit 300 may be disposed above the pouch unit 100 to seal the filling space 120 of the pouch unit 100.

[0148] Referring to FIGS. 13A and 13B, the content filling device 500 can descend and contact one end of the container device 1. More specifically, if the seal block support portion 520 forms a state of contacting the seal unit support portion 310 of the selective seal unit 300, the selective seal unit opening 350 that opens above the selective seal unit 300 is closed, and the seal unit internal space 340 is sealed. By sealing the seal unit internal space 340, the liquid content can be stably filled into the filling space 120 while having a certain pressure through the nozzle portion 510.

[0149] In some embodiments, the seal block support portion 521 and the nozzle cover portion 522 are formed to have a predetermined step. At this time, the outer diameter of the nozzle cover portion 522 is formed smaller than the inner diameter of the seal unit support portion 310 of the selective seal unit 300. Thereby, the seal block support portion 521 can stably make surface contact with the seal unit support portion 310 to seal the seal unit internal space 340, and the liquid content can be stably filled into the filling space 120 of the pouch unit 100 through the nozzle portion 510 covered by the nozzle cover portion 522.

[0150] In other embodiments, the seal block support portion 521 and the nozzle cover portion 522 are continuously formed in a tapered shape. At this time, a part of the outer peripheral surface of the seal block support portion 521 can be in line contact with the inner diameter of the seal unit support portion 310 of the selective seal unit 300 to seal the seal unit internal space 340, and the liquid content can be stably filled into the filling space 120 of the pouch unit 100 through the nozzle portion 510 covered by the nozzle cover portion 522.

[0151] Hereinafter, the content filling device 500' according to another disclosed embodiment of the present invention will be additionally described.

[0152] FIG. 14 is a diagram for explaining the content filling device 500' according to another disclosed embodiment of the present invention.

[0153] Referring to FIG. 14, the disclosed content filling device 500' according to another embodiment of the present invention is similar to the content filling device 500 according to one embodiment of the present invention described above. However, the disclosed content filling device 500' according to another embodiment of the present invention can further include an adapter part 560. As an example, the adapter part 560 can cover the outer surface of the seal block part 520, and the adapter part 560 can cover at least a part of the bent outer surface of the external container 200. In a container device production factory where the content filling device 500' is applied, the content filling device 500' may descend to the side of the container device 1 to fill the liquid content. However, in some cases, the container device 1 may rise to the side of the content filling device 500' to be filled with the liquid content. In the latter case, the content filling device 500' and the container device 1 may not be firmly fixed in position. To solve such problems, the disclosed content filling device 500' according to another embodiment of the present invention additionally includes an adapter part 560. The adapter part 560 covers a part of the outer surface of the external container 200 to position the nozzle part 510 and the seal block part 520 relative to the selective seal unit 300, and can seal the internal space 340 of the seal unit. If necessary, the inside of the adapter part 560 can include a protrusion corresponding to the protrusion formed on the outer peripheral surface of the neck part 220 of the external container 200. With this protrusion structure, the adapter part 560 and the external container 200 can be rotationally coupled to each other, whereby the nozzle part 510 and the seal block part 520 are positioned relative to the selective seal unit 300, enabling stable sealing of the internal space 340 of the seal unit, and having the advantage of easily guiding the nozzle part 510 to the slit 331 to enable stable filling of the liquid content.

[0154] By using the pouch unit 100 according to the disclosed embodiment of the present invention in this way, since the liquid content can be easily filled without physically stretching the pouch unit 100 by the sliding movement of the nozzle part 510 as in the prior art, there is an advantage of preventing damage to the pouch unit 100 during the process of filling the pouch unit 100.

[0155] In addition, by using the pouch unit 100 according to the disclosed embodiments of the present invention, the area of contact with the inner surface 212 of the outer container 200 by at least one pouch unit body recess 111 is reduced during the process of the pouch unit 100 expanding. Therefore, the frictional force generated during the process of the pouch unit body 110 expanding due to the filling of the liquid content is reduced, and there is an advantage that the liquid content can be easily filled.

[0156] Moreover, by using the container device 1 according to the disclosed embodiments of the present invention, the filling space 120 of the pouch unit 100 is selectively communicated according to the shape of the selective seal unit 300, minimizing the contamination of the content, and there is an advantage that the content can be easily filled.

[0157] Furthermore, by using the content filling device 500 according to the disclosed embodiments of the present invention, the internal space 340 of the seal unit can be sealed to form a pressure that facilitates the injection of the liquid content, and there is an advantage that the liquid content can be stably and easily filled into the filling space 120.

[0158] As described above, the preferred embodiments of the present invention have been explained. However, the present invention is not limited thereto, and it can be variously modified and implemented within the scope of the claims, the detailed description of the invention, and the appended drawings, and it goes without saying that this also belongs to the scope of the present invention.
