Description

Technical Field

[0001] This invention relates to a double-lid container, and more specifically, to a double-lid container for aseptic filling, a double-lid for aseptic filling, and an aseptic filling process using the same, all of which are applicable to aseptic filling methods. Background Technology

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

[0003] Beverage containers typically contain drinkable liquid beverages or tea, and the contents can only be consumed after the lid is opened.

[0004] However, when taking oral medications such as health supplements or vitamins, it is common to drink them with beverages (in this case, health drinks).

[0005] Containers that allow beverages and pills to be consumed simultaneously or together have been developed and marketed.

[0006] Especially in the case of beverage containers, aseptic filling methods that utilize aseptic filling techniques and aseptic packaging methods are applicable during the packaging process to prevent virus penetration.

[0007] However, aseptic filling methods using aseptic filling techniques are not applicable to containers that can be used to hold beverages and pills simultaneously due to their unique structure that fills both solid and liquid contents.

[0008] Furthermore, while existing double-lid containers allow beverages and tablets to be taken simultaneously or together, problems can occur with the tablets during medium to long-term storage due to moisture (liquid) from the internal beverage and moisture from the external environment penetrating the container.

[0009] Recently, although products that allow for the simultaneous consumption of tablets and liquids have been continuously developed and launched into the market, the problem of bacterial contamination has become prominent due to the unique characteristics of storing and consuming solid and liquid products simultaneously. Furthermore, the long-term storage of solid tablets is complicated by the potential for liquid and external moisture penetration.

[0046] Hereinafter, with reference to the accompanying drawings, we will observe the structure and function of the aseptic filling double-lid container and the aseptic filling double-lid according to the present invention.

[0047] The detailed description of specific embodiments illustrated in the accompanying drawings is interpreted in conjunction with the drawings themselves, which are considered part of the overall description of the invention. References to directions or orientations are merely illustrative and are not intended to limit the scope of the invention in any way.

[0048] Specifically, terms indicating position such as "down," "up," "horizontal," "vertical," "upper side," "lower side," "upward," "downward," "upper part," and "lower part," or their derivatives (e.g., "towards horizontal," "downward," "upward," etc.), should be understood with reference to the accompanying drawings and related descriptions. In particular, since these relative terms are only for the convenience of explanation, it is not required that the device of the present invention be configured or operated in a specific orientation.

[0049] Furthermore, terms such as “installed,” “attached,” “connected,” “linked,” “interconnected,” etc., which indicate the interrelationship between components, may, unless otherwise stated, mean a state in which individual components are directly or indirectly attached, connected, or fixed. This should be understood to encompass not only the state of being movably attached, connected, or fixed, but also the state of being immovable.

[0050] When assigning reference numerals to the constituent elements of the various figures, care should be taken to ensure that the same constituent elements are marked with the same numerals as much as possible, even if they are marked in other figures. Furthermore, in describing the present invention, descriptions of known structures or functions will be omitted if it is determined that such descriptions might confuse the focus of the invention.

[0051] Figure 1 This is a schematic diagram of a double-cap container for aseptic filling according to an embodiment of the present invention. Figure 2This is an exploded view of a double-cap container for aseptic filling according to an embodiment of the present invention. Figure 3 This is a cross-sectional view of a double-lid container for aseptic filling according to an embodiment of the present invention.

[0052] Aseptic filling is a technology that involves sterilizing raw materials at ultra-high temperature and then immediately cooling them to room temperature before filling them in a sterile room. Because the beverage is exposed to high temperatures for a shorter period of time and the entire process is carried out in a sterile environment, it has the advantage of significantly reducing the risk of microbial growth.

[0053] To enable this type of aseptic filling method to be applicable to products that are stored and consumed simultaneously with solids and liquids, the present invention proposes a double-lid container to which the aseptic filling method is applicable. It is particularly noteworthy that the proposed structure for simultaneous storage of solids and liquids and for the container to be manufactured in an aseptic engineering manner is the first of its kind in the industry.

[0054] As in Figures 1 to 3 As shown in the figure, a double-lid container 100 with a double-isolation structure according to an embodiment of the present invention can be formed, including: a bottle body 110, an outer lid 120, an inner lid 130, and an outer lid hole cap 140.

[0055] The bottle body 110 has the shape of a bottle and can store liquids such as beverages, with an opening at the top to allow the beverage to enter and exit.

[0056] The outer cover 120 and the inner cover 130 can form a double cover.

[0057] The outer cap 120 functions as a cap that covers the upper opening of the bottle body 110.

[0058] The inner lid 130 can store solids such as tablets (including powders) inside, and can serve as a connecting medium between the double-lid container 100 and the outer lid 120.

[0059] The inner cap 130 is separated so that the liquid and solid contained in the bottle body 110 do not mix with each other, and has a flow path for the liquid contained in the bottle body 110 to flow out to the outside, and can serve as a fastening intermediate medium between the bottle body 110 and the outer cap 120.

[0060] The outer cap 140 is designed to sequentially combine the components in a sterile chamber using an aseptic filling method, allowing tablets (solid) to be dispensed and sealed through the top hole 129 formed on the top of the outer cap 120.

[0061] Below the top hole 129 is an inner cover 132 of an inner cover 130 into which a tablet can be placed.

[0062] In order to be suitable for aseptic filling, it should have a structure that enables sterilization, sequential addition of liquids and solids, and sequential connection and sealing of the connecting components when the components are not joined.

[0063] Therefore, the outer cap 140 acts as a cover when the tablet (solid) is inserted.

[0064] Figure 4 This is a sequence diagram illustrating the assembly and filling process of the double-cap container of the present invention according to the aseptic filling process.

[0065] In order to produce containers for the simultaneous storage and consumption of liquids and solids using aseptic filling methods, the process involves sterilizing each component in its unbound state, sequentially filling each of its contents, and sealing them sequentially, and all processes should be carried out in a sterile room.

[0066] Based on this type of aseptic filling method, the engineering sequence of the present invention is carried out through... Figure 4 Let's observe.

[0067] First, as in (A), the bottle body 110, outer cap 120, inner cap 130 and outer cap hole cap 140 are sterilized at ultra-high temperature in a sterile room in an unassembled state.

[0068] When sterilization is performed while the components are joined, ultra-high temperature sterilization must be performed while the components are not joined because sterilization is not achieved in the fine parts that are joined.

[0069] For example (A), if each component is sterilized at ultra-high temperature, as in (B), the beverage (liquid) is filled through the inlet of the bottle body 110.

[0070] With the beverage filled, as in (C), the inner cap 130 and the outer cap 120 are sequentially fastened at the inlet of the bottle body 110.

[0071] Referring to (D), a top hole 129 is formed on the top of the outer cover 120, through which a tablet (solid) is inserted.

[0072] In this state, as in (E), the top hole 129 of the outer cover 120 is completely sealed after being covered by the outer cover hole cover 140. The seal can be achieved by means of welding or other methods to prevent external opening and closing and to make the outer cover 120 and the outer cover hole cover 140 a complete unit.

[0073] Figure 5 This is a cross-sectional view of the outer cap of a double-layered cap container for aseptic filling according to an embodiment of the present invention.

[0074] The outer cover 120 according to the present invention can perform the function of covering the opening of the bottle body 110.

[0075] Reference Figure 5 The outer cover 120 may be formed, including: a cover side portion 121, a cover top portion 122, an outer cover outer portion 123, an inner cover inner portion 124, first and second threads 125a and 125b, a first sealing protrusion 126, and a second sealing groove 127.

[0076] The top center of the outer cover 120 is provided with a cover top 122, and a cover side 121 may be provided on the outer periphery of the cover top 122.

[0077] The outer cover side portion 123 is formed outward from the cover side portion 121, and the inner cover side portion 124 is formed by being separated from the outer cover side portion 124 by a preset interval.

[0078] The outer side portion 123 and the inner side portion 124 of the outer cover can be formed into the cylindrical side portion 121 of the cover side portion in a cylindrical shape.

[0079] A first thread 125a is formed on the inner side of the outer side portion 123 of the outer cap, which can be engaged and fastened with the outer thread of the bottle body 110. A second thread 125b is formed on the outer side of the inner side portion 124 of the outer cap, which can be engaged and fastened with the thread 138 of the inner cap 130.

[0080] The top of the cover 122 is located at the top center of the outer cover 120 and has a structure that connects to the side of the cover 121.

[0081] The structure in which the first sealing protrusion 126 is engaged with the first sealing groove 139 in the inner cover 130 and the second sealing groove 127 is engaged with the second sealing protrusion 132a in the inner cover 130 can achieve a dual liquid and moisture isolation structure.

[0082] Furthermore, a first air layer forming portion 128 may be formed at the upper end of the inner side portion 124 of the outer cover, which can form an air layer between the outer cover 120 and the inner cover 130 for the purpose of isolating moisture by osmotic pressure.

[0083] The first air layer forming part 128 can be in a shape that is inclined in opposite directions together with the second air layer forming part, so that an air layer is formed between the inner side 124 of the outer cover and the inner side 132 of the inner cover while the outer cover 120 and the inner cover 130 are joined.

[0084] Figure 6 This is a cross-sectional view of the inner lid of a double-lid container for aseptic filling according to an embodiment of the present invention.

[0085] Reference Figure 6 , refer to Figure 3The inner cover 130 can be formed, including: an outer portion 131, an inner portion 132, a bridge 133, a bottom portion 134, a sealing rib 135, a fastening bend 136, a liquid flow portion 137, a thread 138, a first sealing groove 139, and a second sealing protrusion 132a.

[0086] The inner cap 130 has a double container structure with an outer portion 131 and an inner portion 132. A flow path for liquid to flow inside the bottle body 110 is formed in the gap between the outer portion 131 and the inner portion 132. In addition, a bridge 133 can be formed to connect the outer portion 131 and the inner portion 132 to each other.

[0087] A flow path through which the liquid can flow via bridge 133 can be formed between the outer side 131 and the inner side 132 of the inner cover.

[0088] The outer side portion 131 and the inner side portion 132 of the inner cover can be formed into cylindrical side portions with the cylindrical shape of the inner cover 130.

[0089] The bottom part 134 at the lower end of the inner cover 130 can hold solids, and the outer periphery of the bottom part 13 has a shape (storage part) that is formed in the upward direction as the inner side part 132 of the inner cover so as to store tablets.

[0090] Furthermore, an air layer forming part can be formed on the lower outer periphery of the inner cover 132, which, after fastening the outer cover 120, can form an air layer between the outer cover 120 and the inner cover 130 for the purpose of isolating moisture by osmotic pressure.

[0091] The inner cap 130 has a fastening bend 136 on the outer periphery of the top, which is bent downwards to form a structure that can be fastened to the upper end of the bottle body 110.

[0092] A thread 138 may be formed on the inner sidewall of the outer side portion 131 of the inner cover, which can be used to fasten it by threading with the outer cover 120.

[0093] When the outer side of the inner cap 131 is fastened, it is in face-to-face contact with the inner side of the bottle body 110, which further enhances the effect of preventing moisture and air penetration.

[0094] The inner cap 130 has a dual structure of an outer inner cap portion 131 and an inner inner cap portion 132. The gap between the outer inner cap portion 131 and the inner inner cap portion 132 forms a flow path for the liquid inside the bottle body 110 to flow. In addition, a bridge 133 can be formed to connect the outer inner cap portion 131 and the inner inner cap portion 132 to each other.

[0095] Bridge 133 can form a flow path through which liquid can flow between the outer side of the inner cap 131 and the inner side of the inner cap 132 in the bottle body 110.

[0096] As flow paths are formed, the multiple bridges 133 are spaced apart from each other, and while connecting the outer side 131 and the inner side 132 of the inner cover to each other, a flow path space is generated.

[0097] At this time, a first sealing groove 139 is formed between the lower end of the bridge 133 and the lower end of the inner cover 130 to seal with the first sealing protrusion 126, but in order to improve the sealing force, a sealing rib 135 is also formed along the cylindrical direction (ring or strip).

[0098] The sealing rib 135 is formed into a cylindrical shape along the lower end of the inner side 132 of the inner cover in the cylindrical direction, and can be connected to the lower inner end face of the bridge 133.

[0099] The space formed between the sealing rib 135 and the inner side portion 132 of the inner cover forms a first sealing groove 139.

[0100] In the absence of sealing rib 135, although the space formed by bridge 133 and inner cover inner side 132 is formed as first sealing groove 139, the first sealing groove 139 is also formed corresponding to bridge 133 because multiple bridges 133 are formed separately for the formation of flow path space. However, the space without first sealing groove 139 has the problem of losing sealing function.

[0101] Therefore, in order to solve this problem, a sealing rib 135 is formed on the inner side of the lower end of the bridge 133 along the cylindrical direction, so that the first sealing groove 139 itself is formed into a complete circle shape, which improves the sealing force of the first sealing groove 139 and the first sealing protrusion 126 so as to completely prevent moisture or liquid from penetrating into the granular tablets placed in the inner cover 130.

[0102] The bottom surface 134 at the lower end of the inner cover 130 can hold a solid, and the outer periphery of the bottom surface 134 can be formed by an upward protrusion protruding from the bottom surface 134.

[0103] The outer periphery of the top of the connecting part 130 has a fastening bend 136 that is bent downwards to form a structure that can be fastened to the upper end of the bottle body 110.

[0104] A thread 138 may be formed on the inner sidewall of the outer side portion 131 of the inner cover, which is used to fasten it by thread engagement with the outer cover 120.

[0105] The first sealing groove 139 engages with the first sealing protrusion 126 groove of the outer cover 120 to perform the first round of liquid and moisture isolation function, and the second sealing protrusion 132a can engage with the second sealing groove 127 groove of the outer cover 120 to perform the second round of liquid and moisture isolation function.

[0106] The liquid flow section 137 is formed on the outside of the inner side portion 132 of the inner cap and can be formed along the vertical length direction. When opening, the beverage often follows along the thread 138 formed on the inner side portion 131 of the inner cap. In order to prevent the beverage that follows from entering the place where there are pills, the liquid flow section 137 is guided to the inside of the bottle body 110.

[0107] Figure 7 This is a cross-sectional view of the aseptic filling double-cap container according to an embodiment of the present invention.

[0108] like Figure 7 As shown, the double-lid container 100 of the present invention has a structure in which an inner lid 130 is fastened to the inside of the upper opening of the bottle body 110, and an outer lid 120 is fastened thereon.

[0109] The outer cap 120 has a first thread 125a fastened to the thread formed on the outer periphery of the bottle body 110 to have a first fastening structure, and the second thread 125b fastened to the thread 138 of the inner cap 130 to have a second fastening structure, thus having a double fastening structure overall.

[0110] The outer cover 120 consists of an outer cover outer portion 123 and an inner cover inner portion 124, forming a double wall. The first thread 125a of the outer cover outer portion 123 and the second thread 125b of the outer cover inner portion 124 form a screw-tapping connection with the bottle body 110 and the inner cover 130, which can realize multiple external moisture isolation walls.

[0111] Figure 8 This is a diagram illustrating the double-locking and double-isolation structure of a double-lid container for aseptic filling according to an embodiment of the present invention.

[0112] exist Figure 8 For ease of understanding of the double fastening structure and double moisture barrier structure of the double-layer lid container 100 of the present invention, the combination structures A to E are shown respectively.

[0113] The double fastening structure consists of parts A and B. Part A is the first fastening structure part where the first thread 125a of the outer cap 120 is fastened to the thread formed on the outer periphery of the bottle body 110. Part B is the second fastening structure part where the second thread 125b of the outer cap 120 is fastened to the thread 138 of the inner cap 130.

[0114] The dual liquid and moisture barrier structure is in sections C and D. The outer cover 120 and the inner cover 130 are threaded together to achieve a dual moisture barrier structure in sections C and D.

[0115] Part C is the first sealing protrusion 126 of the outer cover 120 and the first sealing groove 139 of the inner cover 130, which together form the first moisture barrier. Because they are pressed into each other while being forcibly fastened in an interlocking manner, the effect of the barrier can be increased.

[0116] In particular, since the first sealing groove 139 connects the lower end faces of the bridge 133 to each other while forming a circular shape along the cylindrical direction, when the first sealing groove 139 and the first sealing protrusion 126 are fastened, the fastening force is increased while the entire cylinder is sealed, thus making it possible to fundamentally prevent the internal flow of liquid.

[0117] Part D is the portion where the second sealing groove 127 of the outer cover 120 and the second sealing protrusion 132a groove of the inner cover 130 combine to form a second moisture barrier. In particular, it can have a structure in which the front end of the second sealing protrusion 132a is in contact with the second sealing groove 127 to form a barrier.

[0118] Furthermore, part E is formed by the first and second air layer forming parts 128 (inclined part), which form an air layer that can function as a buffer layer to isolate moisture by osmotic pressure.

[0119] The features, structures, effects, etc., described in the above embodiments are included in at least one embodiment of the present invention, but are not limited to one embodiment. Furthermore, the features, structures, effects, etc., exemplified in each embodiment can also be combined or modified and implemented by those skilled in the art for other embodiments. Therefore, such combinations and modifications should be interpreted as being included within the scope of protection of the present invention.

[0120] Furthermore, although the above description focuses on embodiments, these are merely examples and not intended to limit the invention. Those skilled in the art will recognize various modifications and applications not mentioned in the examples above, without departing from the essential characteristics of these embodiments. For instance, each constituent element specifically embodied in the embodiments can be modified and implemented. All differences related to such modifications and applications should be interpreted as being included within the scope of the invention as defined by the appended claims.
