[0002] Tea or beverages are contained, sold, and consumed in beverage containers of a certain shape.

[0003] In general, beverage containers contain drinkable liquid beverages or tea, and the cap is opened to drink them.

[0004] However, when taking oral supplements, such as dietary supplements or vitamins, they are often consumed with beverages (in this case, health drinks).

[0005] Containers that allow for simultaneous or combined consumption of beverages and pills are being developed and marketed.

[0006] In particular, for beverage containers, an aseptic filling method of an aseptic packaging method is applied to prevent penetration of viruses during a packaging process.

[0007] However, for the current containers that allow for simultaneous consumption of beverages and pills, the aseptic filling method cannot be applied due to their unique structure that fills solid and liquid contents.

[0008] In addition, the dual-cap container products of the related art address the issue of allowing for simultaneous or combined consumption of beverages and pills; however, there occur cases where mid- to long-term storage leads to problems with the pills due to penetration of moisture (liquid) of the internal beverage and external moisture.

[0009] Recently, although products that allow for simultaneous consumption of pills and liquids are being continuously developed and marketed, the aseptic filling method cannot be applied due to the unique nature of simultaneous storage and consumption of solids and liquids, which has led to the problem of bacterial contamination and has also posed the challenge of difficulty in mid- to long-term storage of solid pills due to penetration of liquids and external moisture.Citation List

[0033] Structures and operational effects of a dual-cap container for aseptic filling and a dual cap for aseptic filling according to an exemplary embodiment of the present invention will be described below with reference to the accompanying drawings.

[0034] The detailed description of the specific exemplary embodiments shown in the accompanying drawings is to be read in conjunction with the accompanying drawings, which are considered to be a part of the entire description of the invention. References to directions or orientations are for convenience of description only and are not intended to limit the scope of the present invention in any way.

[0035] Specifically, terms indicating positions, such as "down, up, horizontal, vertical, upper, lower, upward, downward, top, and bottom" or derivatives thereof (e.g., "horizontally, downwardly, upwardly," etc.) should be understood with reference to both the drawings being described and the related descriptions. In particular, since these relative terms are provided only for convenience of description, it is not required that the device of the present invention be configured or operated in a specific direction.

[0036] In addition, terms indicating a mutual coupling relationship between components, such as "mounted, attached, connected, joined, and interconnected", may refer to a state in which individual components are directly or indirectly attached, connected, or fixed, unless otherwise stated, and should be understood as a term that encompasses not only a state in which they are movably attached, connected, or fixed, but also a state in which they are immovable.

[0037] When adding reference numerals to components in each drawing, it should be noted that the same components have the same numerals as much as possible even though they are shown in different drawings. In addition, when describing the present invention, a detailed description of related known configurations or functions will be omitted if it is determined that the detailed description makes the gist of the present invention unclear.

[0038] FIG. 1 is a perspective view of a dual-cap container for aseptic filling according to an exemplary embodiment of the present invention, FIG. 2 is an exploded perspective view of the dual-cap container for aseptic filling according to the exemplary embodiment of the present invention, and FIG. 3 is an exploded cross-sectional view of the dual-cap container for aseptic filling according to the exemplary embodiment of the present invention.

[0039] An aseptic filling method is an aseptic filling technique of sterilizing a raw material at ultra-high temperatures, then cooling the raw material immediately and filling the same at room temperature in an aseptic chamber. The aseptic filling method has an advantage of significantly reducing the risk of microbial growth because the time the beverage is exposed to high temperatures is shortened and the entire process is conducted in an aseptic environment.

[0040] In order for the aseptic filling method to be applicable to a product for simultaneous storage and consumption of solids and liquids, the present invention proposes a dual-cap container to which the aseptic filling method can be applied, and in particular, it should be noted that proposing a structure that can be manufactured using the aseptic method for a container for simultaneous storage and consumption of solids and liquids is being introduced for the first time in the art.

[0041] As shown in FIGS. 1 to 3, a dual-cap container 100 with a double-blocking structure according to an exemplary embodiment of the present invention may include a bottle 110, an outer cap 120, an inner cap 130, and an outer cap hole cover 140.

[0042] The bottle 110 has a bottle-like shape and can store a liquid, such as a beverage, and an upper end portion thereof is open, allowing the beverage to be poured in and out.

[0043] The outer cap 120 and the inner cap 130 can constitute a dual cap.

[0044] The outer cap 120 functions as a lid that covers an upper end opening portion of the bottle 110.

[0045] The inner cap 130 can store therein a solid (including powder), such as a pill, and can serve as a connecting medium between the dual-cap container 100 and the outer cap 120.

[0046] The inner cap 130 separates the liquid contained in the bottle 110 and the solid from each other so that they are not mixed, has a flow passage through which the liquid contained in the bottle 110 can flow out, and can function as an intermediate medium for fastening the bottle 110 and the outer cap 120.

[0047] The outer cap hole cover 140 allows for introduction of pills (solids) through an upper hole 129 formed in an upper portion of the outer cap 120 and sealing, in order to sequentially couple each component within an aseptic chamber using an aseptic filling method.

[0048] Below the upper hole 129, an inner cap inner portion 132 of the inner cap 130 into which a pill can be introduced is positioned.

[0049] In order to apply the aseptic filling method, it is required to have a structure where sterilization is performed with the respective components uncoupled, liquids and solids are introduced sequentially, and each connecting component is coupled and sealed in sequence.

[0050] To this end, the outer cap hole cover 140 serves as a lid for the outer cap when introducing a pill (solid).

[0051] FIG. 4 is a flow chart showing coupling and filling processes of a dual-cap container according to an exemplary embodiment of the present, according to an aseptic filling method.

[0052] In order to produce containers for simultaneous storage and consumption of liquids and solids using an aseptic filling method, each component should be sterilized in an uncoupled state, followed by sequential filling of each content and coupling through sequential sealing, and all processes should be performed within an aseptic chamber.

[0053] Based on such an aseptic filling method, the process sequence of an exemplary embodiment of the present invention is described with reference to FIG. 4.

[0054] First, as shown in (A), the bottle 110, the outer cap 120, the inner cap 130, and the outer cap hole cover 140 are each subjected to ultra-high temperature sterilization within an aseptic chamber in an uncoupled state.

[0055] If sterilization is performed while the components are coupled, microscopic portions where the components are coupled are not sterilized. Therefore, ultra-high temperature sterilization should be conducted while the components are not coupled.

[0056] When ultra-high temperature sterilization for each component is completed as shown in (A), a beverage (liquid) is filled through the inlet of the bottle 110, as shown in (B).

[0057] When the beverage filling is completed, the inner cap 130 and the outer cap 120 are sequentially fastened to the inlet of the bottle 110, as shown in (C).

[0058] Referring to (D), pills (solids) are introduced through the upper hole 129 formed in the upper portion of the outer cap 120.

[0059] In this state, as shown in (E), the upper hole 129 of the outer cap 120 is covered with the outer cap hole cover 140, which is then completely sealed. The sealing can be done by welding or other methods so that the outer cap 120 and the outer cap hole cover 140 become a single body, preventing them from being opened or closed from the outside.

[0060] FIG. 5 is a cross-sectional view of an outer cap of the dual-cap container for aseptic filling according to the exemplary embodiment of the present invention.

[0061] The outer cap 120 according to the exemplary embodiment of the present invention can perform a function of covering the opening portion of the bottle 110.

[0062] Referring to FIG. 5, the outer cap 120 may include a cap side portion 121, a cap upper end portion 122, an outer cap outer portion 123, an outer cap inner portion 124, first and second screw threads 125a and 125b, a first sealing protrusion 126, and a second sealing groove 127.

[0063] An upper end of the outer cap 120 may have the cap upper end portion 122 positioned at a center, and the cap side portion 121 may be positioned along an outer perimeter of the cap upper end portion 122.

[0064] The cap side portion 121 may have the outer cap outer portion 123 formed on an outer side, and the outer cap inner portion 124 may be formed at a predetermined interval inward of the outer cap outer portion 123.

[0065] The outer cap outer portion 123 and the outer cap inner portion 124 can constitute a circumferential surface side portion of the cap side portion 121 in the form of a circumferential surface.

[0066] The first screw thread 125a is formed on an inner side of the outer cap outer portion 123, enabling it to be coupled and fastened with an outer screw thread of the bottle 110, and the second screw thread 125b is formed on an outer side of the outer cap inner portion 124, enabling it to be coupled and fastened with the screw thread 138 of the inner cap 130.

[0067] The cap upper end portion 122 is positioned at the center of the upper end of the outer cap 120 and has a structure connected to the cap side portion 121.

[0068] The first sealing protrusion 126 is coupled with the first sealing groove 139 of the inner cap 130 in a fitting manner, and the second sealing groove 127 is coupled with the second sealing protrusion 132a of the inner cap 130 in a fitting manner, thereby implementing a double liquid and moisture-blocking structure.

[0069] In addition, an upper end portion of the outer cap inner portion 124 may be further formed with a first air layer forming portion 128 having a structure that can enable an air layer to be formed between the outer cap 120 and the inner cap 130 for the purpose of blocking moisture due to osmotic pressure.

[0070] The first air layer forming portion 128 and the second air layer forming portion may take a form of being inclined in opposite directions to each other so that an air layer is formed between the outer cap inner portion 124 and the inner cap inner portion 132 when the outer cap 120 and the inner cap 130 are coupled.

[0071] FIG. 6 is a perspective view of an inner cap of the dual-cap container for aseptic filling according to the exemplary embodiment of the present invention.

[0072] Referring to FIG. 6, the inner cap 130 may include an inner cap outer portion 131, an inner cap inner portion 132, bridges 133, a bottom portion 134, a sealing rib 135, a fastening bent portion 136, a liquid flow-guide portion 137, a screw thread 138, a first sealing groove 139, and a second sealing protrusion 132a.

[0073] The inner cap 130 has a double container structure of the inner cap outer portion 131 and the inner cap inner portion 132, forms a flow passage through which the liquid inside the bottle 110 can flow between the inner cap outer portion 131 and the inner cap inner portion 132, and can also form the bridges 133 connecting the inner cap outer portion 131 and the inner cap inner portion 132 to each other.

[0074] A flow passage through which the liquid can flow can be formed between the inner cap outer portion 131 and the inner cap inner portion 132 through the bridges 133.

[0075] The inner cap outer portion 131 and the inner cap inner portion 132 can constitute a circumferential surface side portion in the form of a circumferential surface of the inner cap 130.

[0076] A solid may be held on the bottom portion 134 at a lower end portion of the inner cap 130, and the inner cap inner portion 132 is formed upwards along an outer perimeter of the bottom portion 134, thereby forming a shape (storage) that can store pills.

[0077] In addition, an outer perimeter of a lower end of the inner cap inner portion 132 may be further formed with an air layer forming portion having a structure that can enable an air layer to be formed between the outer cap 120 and the inner cap 130 for the purpose of blocking moisture due to osmotic pressure after the outer cap 120 is fastened.

[0078] An outer perimeter of an upper end of the inner cap 130 has the fastening bent portion 136 formed in a downwardly bent shape, leading to a structure that can be fastened to the upper end of the bottle 110.

[0079] An inner wall of the inner cap outer portion 131 may be formed with the screw thread 138, which may be used to be coupled and fastened with a screw thread of the outer cap 120.

[0080] When fastened, an outer surface of the inner cap outer portion 131 comes into contact with an inner surface of the bottle 110 in a surface-to-surface manner, thereby further increasing the effect of blocking moisture and air penetration.

[0081] The inner cap 130 has a double structure of the inner cap outer portion 131 and the inner cap inner portion 132, forms a flow passage through which the liquid inside the bottle 110 can flow between the inner cap outer portion 131 and the inner cap inner portion 132, and can also form the bridges 133 connecting the inner cap outer portion 131 and the inner cap inner portion 132 to each other.

[0082] The bridges 133 can form a flow passage through which the liquid in the bottle 110 can flow between the inner cap outer portion 131 and the inner cap inner portion 132.

[0083] By forming the flow passage, the plurality of bridges 133 are spaced apart from each other to connect the inner cap outer portion 131 and the inner cap inner portion 132 to each other, thereby creating a flow passage space.

[0084] In this case, the first sealing groove 139, which couples with the first sealing protrusion 126 to form a seal, is formed between a lower end portion of the bridge 133 and a lower end portion of the inner cap 130. Additionally, the sealing rib 135 is further formed in a circumferential direction (in the shape of a ring or band) to increase a sealing force.

[0085] The sealing rib 135 is formed in a circumferential surface shape along the lower end of the inner cap inner portion 132 in the circumferential direction and may be formed in contact with lower end surfaces of inner sides of the bridges 133.

[0086] A space between the sealing rib 135 and the inner cap inner portion 132 forms the first sealing groove 139.

[0087] In the absence of the sealing rib 135, the space formed by the bridges 133 and the inner cap inner portion 132 forms the first sealing groove 139; however, since the plurality of bridges 133 are formed spaced apart from each other to form a flow passage space, the first sealing groove 139 is also formed corresponding to the bridge 133, and accordingly there is a problem that the sealing function is lost in the space where the first sealing groove 139 is not present.

[0088] Accordingly, to solve this problem, the sealing rib 135 is further formed in a circumferential direction on the inner side surfaces of the lower ends of the bridges 133 so that the first sealing groove 139 itself is formed in a perfect circular shape, thereby increasing the sealing force between the first sealing groove 139 and the first sealing protrusion 126 to completely block moisture or liquid from penetrating into the granule pills positioned inside the inner cap 130.

[0089] A solid may be held on the bottom portion 134 at the lower end of the inner cap 130, and upward protrusion portions protruding from the bottom portion 134 may be formed along the outer perimeter of the bottom portion 134.

[0090] The outer perimeter of the upper end of the inner cap 130 has the fastening bent portion 136 formed in a downwardly bent shape, leading to a structure that can be fastened to the upper end of the bottle 110.

[0091] The inner wall of the inner cap outer portion 131 may be formed with the screw thread 138, which is used to be coupled and fastened with the screw thread of the outer cap 120.

[0092] The first sealing groove 139 is coupled with the first sealing protrusion 126 of the outer cap 120 in a fitting manner to primarily perform a liquid and moisture blocking function, and the second sealing protrusion 132a is coupled with the second sealing groove 127 of the outer cap 120 in a fitting manner to secondarily perform a liquid and moisture blocking function.

[0093] The liquid flow-guide portion 137 is formed on an outer surface of the inner cap inner portion 132 and can be formed in a vertical length direction. Upon opening, cases occur frequently in which the beverage comes up along the screw thread 138 formed on the inner cap outer portion 131. To prevent the beverage coming up from entering an area where pills are located, the liquid flow-guide portion 137 guides the beverage into the bottle 110.

[0094] FIG. 7 is a fastening cross-sectional view of the dual-cap container for aseptic filling according to the exemplary embodiment of the present invention.

[0095] As shown in FIG. 7, the dual-cap container 100 according to the exemplary embodiment of the present invention has a structure where the inner cap 130 is fastened into the upper end opening portion of the bottle 110 and the outer cap 120 is fastened over the inner cap.

[0096] The first screw thread 125a of the outer cap 120 is fastened to the screw thread formed on the outer perimeter of the bottle 110 to have a first fastening structure, and the second screw thread 125b is fastened to the screw thread 138 of the inner cap 130 to have a second fastening structure, resulting in a double-fastening structure as a whole.

[0097] A dual wall is formed by the structure of the outer cap outer portion 123 and outer cap inner portion 124 of the outer cap 120, and the screw tab fastening with the bottle 110 and the inner cap 130 is achieved by the first screw thread 125a of the outer cap outer portion 123 and the second screw thread 125b of the outer cap inner portion 124, which enables formation of multiple external moisture blocking walls.

[0098] FIG. 8 is a view showing a structure of double fastening and double blocking of the dual-cap container for aseptic filling according to the exemplary embodiment of the present invention.

[0099] FIG. 8 shows coupling structures A to E, respectively, for the convenience of understanding the double-fastening structure and double moisture-blocking structure of the dual-cap container 100 according to the exemplary embodiment of the present invention.

[0100] The double-fastening structure is composed of parts A and B. Part A is the first fastening structure part where the first screw thread 125a of the outer cap 120 and the screw thread formed on the outer perimeter of the bottle 110 are fastened, and part B is the second fastening structure part where the second screw thread 125b of the outer cap 120 and the screw thread 138 of the inner cap 130 are fastened.

[0101] The double liquid and moisture-blocking structure is composed of parts C and D. The outer cap 120 and inner cap 130 are screw-coupled and coupled, forming a double moisture-blocking structure in parts C and D.

[0102] Part C is where the first sealing protrusion 126 of the outer cap 120 and the first sealing groove 139 of the inner cap 130 are coupled in a fitting manner to form a first moisture-blocking wall, and the forcible fastening of press-fitting the protrusion and the groove each other can enhance the effectiveness of the blocking wall.

[0103] In particular, the first sealing groove 139 is formed in a circular shape in the circumferential direction while connecting the lower end surfaces of the bridges 133. This increases the fastening force when fastening the first sealing groove 139 and the first sealing protrusion 126, while simultaneously enabling sealing over the entire circumference, completely blocking the inflow of liquid into the interior.

[0104] Part D is where the second sealing groove 127 of the outer cap 120 and the second sealing protrusion 132a of the inner cap 130 are coupled in a fitting manner to form a second moisture-blocking wall, and in particular, has a structure where a blocking wall is formed as the distal end of the second sealing protrusion 132a comes into contact with the second sealing groove 127.

[0105] In addition, part E allows for the formation of the air layer by the first and second air layer forming portions 128 (inclined portions), and the air layer can serve as a buffer layer for the purpose of blocking moisture due to osmotic pressure.
