Description

Double-packaged container with full contents discharge

[0001] The present invention relates to a double packaging container for discharging all contents, more specifically to a synthetic resin packaging container, and more specifically to a PET packaging container.

[0002] Specifically, it consists of an external second container that houses an internal first container, and a central concentrator is formed at the bottom of the storage section of the first container to allow the internal fluid to gather in the central section, so that a tube connected to a pump or dropper extends to the central concentrator to enable the entire contents to be discharged.

[0003] Also, the first container can only use one mold model for each capacity, and only a single model can be used for built-in fluid discharge parts such as pumps. As needed, only the shape of the second container can be changed and adopted, making it suitable for small-quantity production of a wide variety of products, while inventory and logistics management can be drastically improved even during mass production. Design diversification is possible without difficulty, and unit price competitiveness is excellent.

[0004] Furthermore, it relates to a double packaging container suitable for storing cosmetics, beverages, liquid detergents, shampoos, rinses, etc., which can improve productivity by unifying the inner and outer containers with synthetic resins, especially PET materials that apply blow molding, which has superior productivity compared to injection molding, and can increase the recycling rate of separated waste, and which can buffer the impact of external temperature changes on the internal fluid.

[0005] Numerous technologies related to dual containers have been proposed in the past.

[0006] For example, there is Patent Registration No. 10-1900419 (September 13, 2018) [Double Container].

[0007] This registered patent includes a nozzle part that discharges contents through a discharge port by pressure applied by a user; a pump assembly that discharges the contents according to the pressure applied to the nozzle part; an inner container including a first receiving part that receives the contents and a first rim part formed above the first receiving part and on which at least a part of the pump assembly is received and seated; an outer container including a second receiving part that receives the inner container and a second rim part formed above the second receiving part; and a shoulder part that is detachably coupled to the second rim part of the outer container and pressurizes the inner container according to the coupling to tightly fix the inner container to the outer container.

[0008] A double container structure consisting of an inner container and an outer container is formed, and by manufacturing the outer container through blow molding, a unique design, volume, and aesthetic appeal due to curved surfaces that cannot be found in containers manufactured through conventional injection molding can be provided, and despite the rich volume, the thickness of the container can be reduced through blow molding, thereby lowering the manufacturing cost and process difficulty.

[0009] There is also patent registration number 10-2130150 (June 29, 2020) [Double container with reinforcement function].

[0010] This registered patent relates to a double container that divides the container into an inner and outer cylinder and provides a space for insulation between the inner and outer cylinders, and has a reinforcing function to minimize deformation of the double container due to heating and to improve heat blocking efficiency while strengthening the connection between the inner and outer cylinders.

[0011] As a reinforcing member is provided for reinforcing the concave groove at the bottom of the double container, the bottom part of the double container is supported during air expansion due to air heating between the inner and outer cylinders during heating of the double container, thereby minimizing deformation of the shape of the bottom part of the double container due to the expanded air pressure.

[0012] Furthermore, there is patent registration number 10-2271373 (June 24, 2021) [Double Container].

[0013] This registered patent includes a nozzle part through which contents are discharged through a discharge port by pressure applied by a user; a pump assembly for discharging the contents according to the pressure applied to the nozzle part; an inner container including a first receiving part for receiving the contents and a first rim part formed above the first receiving part and for receiving and settling at least a part of the pump assembly; an outer container including a second receiving part for receiving the inner container and a second rim part formed upward from the second receiving part; and a shoulder part detachably coupled to the second rim part of the outer container and pressurizing the inner container according to the coupling to tightly fix the inner container to the outer container, wherein the outer container is made of a glass material.

[0014] A double container structure composed of an inner container and an outer container is formed, and by composing the outer container with a retaining material, a more luxurious aesthetic can be provided. When the inner container is accommodated in the outer container, a primary bond is performed through the inner container's fixing edge and anti-rotation protrusion and the outer container's second edge and anti-rotation groove, and in addition, a secondary bond is performed between the inner container and the outer container through the shoulder portion, thereby providing a more solid double bond structure.

[0015] In addition, there is patent registration number 10-2693814 (August 6, 2024) [Double container for cosmetics].

[0016] This registered patent relates to an eco-friendly double container for cosmetics in which each part of the double container can be easily separated and combined, and all parts that make up the container can be recycled.

[0017] The contents container, shoulder contents container, shoulder, pump, outer container, and overcap can be easily assembled and disassembled, so it is very convenient to use, and all disassembled parts are made of plastic material, so all parts are recycled, which creates an excellent effect.

[0018] However, the prior art, including these prior documents, is unrelated to providing a concentrated portion at the bottom of the storage portion of the inner container among the inner and outer double containers to enable the entire contents to be discharged, and is also unrelated to the technology of manufacturing both the inner and outer containers from PET material.

[0019] Accordingly, the present invention provides a double packaging container comprising an external second container that houses an internal first container, and a central portion formed at the bottom of the storage portion of the first container to allow the internal fluid to gather, and a tube connected to a pump or dropper extends to the central portion to enable the entire contents to be discharged.

[0020] In addition, the present invention provides a packaging container in which adhesive retention grooves are formed in some or all of the first and second joints of the first and second containers, thereby going beyond simple physical joints through interlocking projections and grooves to completely bonding the two containers by adhesive, thereby maintaining the sturdiness of the bonded state even during various shocks and vibrations generated during product production, distribution, and use.

[0021] Furthermore, the present invention aims to provide a packaging container in which a stop portion is formed at the upper end of the first and second connecting portions to be mutually connected to promote physical connection, and a pedestal is formed at the center of the bottom surface of the second container to support the lower outer surface of the concentrated portion of the first container, thereby protecting the concentrated portion of the relatively thin first container where the load is concentrated.

[0022] In addition, the present invention aims to provide a packaging container having a non-bonding label mounting portion that does not use adhesive by introducing a non-bonding type label mounting portion including first and second left and right hooks to a second body.

[0023] In addition, the present invention aims to provide a packaging container having a non-bonding label mounting portion, in which the mounting portion further has a third or fourth catch at the lower or upper portion to further improve the stability of the label mounting state.

[0024] Furthermore, the first to fourth catches of the present invention have a structure that does not protrude in a radial direction more than the outer surface of a radially symmetrical or asymmetrical body centered on a discharge portion, thereby maintaining a smooth appearance, thereby providing a packaging container having a non-bonding label mounting portion that enables protection of a label mounting portion and a label mounted thereon.

[0025] In addition, the present invention aims to provide a packaging container having a non-bonding label mounting portion in which the label back contact surface of the mounting portion is a concave surface so as to ensure the stability of the bonding state of the mounted label.

[0026] Furthermore, the present invention aims to provide a packaging container having a non-bonding label mounting portion in which the concave surface has a left-right curve shape, an up-down curve shape, or both, thereby configuring various label mounting portions to ensure product design diversity.

[0027] In order to achieve the above purpose, the double packaging container for discharging all contents according to the present invention is

[0028] An internal first container having a first body connected to the discharge portion and forming a storage portion; and

[0029] An external second container having a second connecting portion provided at the top to be connected to a first connecting portion around the discharge portion of the first container, and a second body that houses the first body in a spaced-apart form;

[0030] The storage section of the first body is characterized in that a central portion is formed at the bottom to allow the internal fluid to gather.

[0031] Also, in the double packaging container with full discharge of contents according to the present invention,

[0032] An adhesive retention groove is formed in the first or second joint portion, or both,

[0033] A stopper is formed on the upper part of the first and second connecting parts to be mutually connected,

[0034] It is preferable that a pedestal be formed in the center of the bottom surface of the second container to support the lower outer surface of the concentrated portion of the first container.

[0035] Meanwhile, the packaging container according to the present invention has a non-bonding label mounting portion, in which case

[0036] A non-bonding label mounting part including first and second hanging protrusions on the left and right sides is provided on the second body of the second container,

[0037] This mounting portion is characterized by having a recessed structure that does not protrude in a radial direction further than the outer surface of a radially symmetrical or asymmetrical body centered on the discharge portion.

[0038] In addition, in a packaging container having a non-bonding label mounting portion according to the present invention,

[0039] The above mounting part further has a third or fourth catch on the lower or upper side,

[0040] The back contact surface of the label of the above mounting part is a concave surface,

[0041] The above concave surface may be in the form of a left-right curve, an up-down curve, or both.

[0042] It is preferable that the above-mentioned catch has a structure that does not protrude in a radial direction further than the outer surface of the radially symmetrical or asymmetrical body centered on the discharge portion.

[0043] The double packaging container for full discharge of contents according to the present invention is composed of an outer second container that receives an inner first container in a separate manner, and a central portion is formed at the bottom of the storage portion of the first container to allow the internal fluid to gather in the central portion, so that a tube connected to a pump or a dropper extends to the central portion to enable full discharge of contents, and an adhesive retention groove is formed on some or all of the first and second connecting portions of the first and second containers, so that the two containers are completely connected by adhesive beyond the simple physical connection through interlocking projections and grooves, and the sturdiness of the connection is maintained even in the case of various shocks and vibrations generated during product production, distribution, and use, and further, a mutually connected stop portion is formed at the top of the first and second connecting portions to promote physical connection, and a pedestal is formed at the center of the bottom of the second container to support the lower outer surface of the central portion of the first container, so that the central portion where the load of the relatively thin first container is concentrated can be protected, and ultimately, according to capacity. The first container uses only one mold model, and only a single model of built-in fluid discharge parts such as pumps can be used, and only the shape of the second container can be changed and adopted as needed, so it is suitable for small-scale production of a wide variety of products, but inventory and logistics management can be drastically improved even in mass production, design diversification is possible without difficulty, and unit price competitiveness is excellent. Furthermore, productivity can be improved by unifying the inner and outer containers with PET material that applies blow molding, which has superior productivity compared to synthetic resin, especially injection molding, and the recycling rate for separate collection can be increased. In addition, it can cushion the impact of external temperature changes on the built-in fluid, so it is suitable for storing cosmetics, beverages, liquid detergents, shampoos, rinses, etc.

[0044] Meanwhile, the packaging container equipped with a non-bonding label mounting portion is environmentally friendly because it does not use adhesive by introducing a non-bonding type label mounting portion including the first and second hanging protrusions on the left and right sides on the second body of the second container, and furthermore, the mounting portion may further have third and fourth hanging protrusions on the lower or upper sides so that the stability of the label mounting state can be further improved, and furthermore, the first to fourth hanging protrusions have a structure that does not protrude radially from the outer surface of the radially symmetrical or asymmetrical body centered on the discharge portion, thereby maintaining a smooth appearance, thereby enabling the protection of the label mounting portion and the label mounted thereon, and furthermore, since the label back contact surface of the mounting portion is a concave surface, the stability of the combined state of the mounted label is secured, and furthermore, since the concave surface has a left-right curve shape, an up-down curve shape, or both, various label mounting portions can be configured, and ultimately, a mounting portion for a label for identification, description, manufacturer, trademark, etc. of the contents is provided on the observation surface of the body forming the contents storage portion, so that the label can be simply inserted into the insertion portion without using the existing label combining method such as an attachment method or a heat shrink film method, and the concave The film-type label in the insertion section is prevented from being separated by the force that causes the label end to be caught on the upper and lower left and right sides or the lower and right sides of the mounting section, thereby maintaining a firmly inserted and connected state. When discarding, the label can be easily removed, and no foreign substances such as adhesive remain, ultimately allowing only pure packaging containers such as PET materials to be separated and discharged.

[0063] The double packaging container (V) for discharging all contents according to the present invention is composed of first and second containers (V1, V2), as shown in the cross-sectional view of FIG. 1.

[0064] The internal first container (V1) has a first body (V1b) equipped with an upper discharge portion (V1d) and a storage portion (V1s) for storing contents, i.e., internal fluids. The discharge portion (V1d), shaped like a bottle spout, is provided with a screw portion for connecting a cap, pump, or dropper. Connected to the discharge portion, the storage portion (V1s) contains internal fluids such as cosmetics, beverages, liquid detergents, shampoos, and rinses.

[0065] The external second container (V2) has a second connecting portion (V2c) provided at the top that is connected to the first connecting portion (V1c) around the discharge portion (V1d) of the first container, and has a second body (V2b) that embeds the first body (V1) in a spaced-apart form, i.e., with a gap (g).

[0066] One of the key points of the double packaging container (V) of the present invention that discharges all contents is that a concentrating portion (V1f) is formed at the bottom of the storage portion (V1s) of the first body (V1b) to allow the built-in fluid to gather in the central portion.

[0067] A tube (T) connected to a pump or dropper extends to the concentrator (V1f) to enable the discharge of all contents.

[0068] Meanwhile, the double packaging container (V) for discharging all contents according to the present invention has an adhesive retention groove (V1a) formed in the first or second connecting portion (V1c, V2c) or both that are in contact with each other.

[0069] As can be seen in the drawing in the upper right dashed line circle of Fig. 1, the adhesive retention groove (V1a) is formed only around the first joint portion (V1c) and around the first joint portion, but may also be formed in the second joint portion as needed, and two or three may be formed instead of one ring.

[0070] Also, when assembling, it may be appropriate to assemble the two containers by turning the first and second containers (V1, V2) upside down, that is, with the discharge portion (V1d) facing downward, in order to prevent the inflow of foreign substances. In this case, it is preferable that the cross-sectional shape of the retention groove (V1a) be similar to the Arabic numeral '7' or 'Γ' so that when the adhesive is injected into the starting point of the narrow lower groove, the adhesive flows and stays in the wide groove so that the adhesive does not leak out of the retention groove.

[0071] In this way, through the adhesive retention groove, the solidity of the bond is maintained even during various shocks and vibrations that occur during the production, distribution, and use of the product through the complete bonding of the two containers by the adhesive, going beyond the simple physical bonding through the interlocking projections and grooves.

[0072] As such, the double packaging container (V) for discharging all contents according to the present invention can be seen in the drawings within the lower two dashed line blocks of FIG. 1 and FIG. 1,

[0073] By capacity, the first container (V1) can only use one mold model, and the built-in fluid discharge parts such as pumps and droppers can only use a single model, and only the shape of the second container (V2) can be varied and adopted as needed, making it suitable for small-quantity production of a wide variety of products, while inventory and logistics management can be drastically improved even in mass production, design diversification is possible without difficulty, and unit price competitiveness is excellent.

[0074] Next, the double packaging container (V) for discharging all contents according to the present invention is configured to secure physical connection by forming a stopper (V1h, V2h) that is mutually connected to the upper end of the first and second connecting portions (V1c, V2c). The first stopper (V1h) has a circular protrusion shape, and the second stopper (V2h) has a circular groove shape, and they are connected by interlocking or interlocking with each other.

[0075] In addition, as can be seen in the drawing in the lower right-hand dashed line circle of FIG. 1, the present invention has a pedestal (V2p) formed at the center of the bottom surface of the second container (V2) to support the lower outer surface of the concentrated portion (V1f) of the first container (V1), thereby protecting the concentrated portion where the load of the relatively thin first container is concentrated.

[0076] As described above, the double packaging container (V) for full discharge of contents according to the invention can improve productivity by unifying the inner and outer containers with synthetic resin, especially PET material that applies blow molding that has superior productivity compared to injection molding, and can increase the recycling rate of separated waste. In addition, the shock of external temperature change applied to the internal fluid can be buffered through the unique configuration of the double container and the heat and shock transmission blocking function through the gap (g).

[0077] Meanwhile, a second container (V2) equipped with a non-bonding label mounting portion among the double containers according to the present invention is examined.

[0078] As can be seen in the various second container (V2) cities of FIG. 2, the second container (V2) equipped with a non-bonding label (L) mounting portion according to the present invention has a second connecting portion (V2c) that is connected to the first connecting portion (V1c) of the first container (V1) formed integrally with the second body (V2b) that forms the first container (V1) separation receiving portion, and may be a packaging container made of PET material blow-molded from a preform or other synthetic resin packaging container injection-molded in consideration of productivity and unit price competitiveness.

[0079] The second container (V2) second body (V2b) has a label (L) mounting portion formed at one or more locations.

[0080] A non-bonding label mounting part including first and second left and right hanging protrusions is provided on the second body (V2b).

[0081] This mounting portion has a recessed structure that does not protrude radially further than the outer surface of the radially symmetrical or asymmetrical body centered on the discharge portion.

[0082] Through this, the smooth appearance of the second container (V2) second body (V2b) is maintained, and even when the packaging containers are bundled and arranged in contact, the label mounting portion and the label provided thereon are protected during production, transportation, display, and post-purchase movement, and further, damage to the packaging containers can be prevented.

[0083] Specifically, the above-mentioned mounting part has first and second catches (J1, J2) on the left and right, and may additionally have third and fourth catches (J3, J4) on the lower or upper side.

[0084] In particular, it is preferable that the label back contact surface of this mounting portion, which has a structure recessed into the outer surface of the second body (V2b), forms a concave surface (C).

[0085] In addition, the catches (J1, J2, J3, J4, j5) have a structure that does not protrude in a radial direction more than the outer surface of the radially symmetrical or asymmetrical second body (V2b) centered on the discharge portion (V3), thereby firmly guaranteeing the function of the inserted mounting portion itself, and thus more perfectly protecting the mounting portion, the label, and the packaging container itself.

[0086] This concave surface (C) mounting portion is provided with a mounting portion for a label (L) for identification, description, manufacturer, trademark, etc. of the contents on the observation surface of the second body (V2b) forming the contents storage portion, and when the label is simply inserted into the insertion portion without using the existing label joining method such as the attachment method or the heat shrink film use method, the end of the label (L) corresponding to the left and right sides or the left and right upper and lower sides or the left and right lower hanging protrusions (J1, J2, J3, J4) of the mounting portion is caught by the force of the film-type label (L) in the concave insertion portion to restore it to a flat shape, so that the label is not separated and is firmly inserted and joined.

[0087] When discarding, labels can be easily removed, no foreign substances such as adhesives remain, and only pure packaging containers made of PET materials can be separated and disposed of, maximizing eco-friendliness. In addition, safety can be improved as producers and consumers are not exposed to harmful adhesives, pressure-sensitive adhesives, or gases or residues generated during the heating process of heat-shrinkable films.

[0088] Specifically, the concave surface (C) may be in the form of a left-right curve (C1) (Fig. 2 [B], [D]), an up-down curve (C2) (Fig. 2 [A], [C]), or both.

[0089] In the case of the concave surface (C) of the left and right curves (C1) of Fig. 2 [B], [D], the first and second catches (J1, J2) have a catch-type structure in which the ends protrude toward each other, as can be seen in the cross-sectional view within the upper left dashed line circle.

[0090] As can be seen in the cross-sectional view within the dashed line in the lower left, it has a flat, non-locking structure up to the ends of the third and fourth locking jaws (J3, J4).

[0091] Fig. 2 [B] is formed only with the first, second, and third catches (J1, J2, J3), so that the label (L) can be combined from the top to the bottom and the label (L) can be combined with the mounting part (M2).

[0092] Fig. 2 [D] shows that both the third and fourth catches (J3, J4) are formed, and for example, the left end of the label (L) is first fitted to the first catch (J1) and then the right end of the label is fitted to the second catch (J2) to attach the label (L) to the mounting portion (M4).

[0093] In comparison, in the case of the concave surface (C) of the upper and lower curves (C2) of FIG. 2 [A], [C], the first and second catches (J1, J2) have a flat, non-catching structure up to the end, as can be seen in the cross-sectional view within the upper left dashed line circle.

[0094] As can be seen in the cross-sectional view in the lower left dashed line, it has a hook-type structure with the ends protruding toward the top or bottom of the third and fourth hooks (J3, J4).

[0095] Fig. 2 [A] is formed only with the first, second, and third catches (J1, J2, J3), so that the label (L) can be combined from the top to the bottom to be combined with the mounting portion (M1).

[0096] In Fig. 2 [C], both the third and fourth catches (J3, J4) are formed, and for example, the lower end of the label (L) is first fitted to the third catch (J3) and then the upper end of the label is fitted to the fourth catch (J4) to attach the label (L) to the mounting portion (M3).

[0097] Meanwhile, in the three consecutive dashed line circles on the upper right of Fig. 2 [D], as an additional modified example, the mounting part has a central protrusion (p1, p2, p3).

[0098] To accommodate this protrusion, the label (Lm) is formed with a hollow (Lh).

[0099] This hollow (Lh) corresponds to the shape of the protrusions (p1, p2, p3), and its size is slightly smaller than the outer end of the protrusions.

[0100] After joining, the hollow (Lh) circumferential flange is additionally hung on the fifth catch (j5) to ensure the firm fixation of the label (Lm) to the mounting part, and various designs can be secured to satisfy the diversification of product composition.

[0101] In addition, the flat protrusion (p1), the concave protrusion (p2), and the convex protrusion (p3) do not protrude further radially than the outer surface of the radially symmetrical or asymmetrical second body (V2b) centered on the discharge portion (V3).

[0102] Furthermore, each of the upper, lower, left, right and center catches (J1, J2, J3, J4, j5) may be continuous or discontinuous, and the upper, lower, left and right catches may or may not be interconnected.

[0103] And the shape of the fifth jaw (j5) can be circular or non-circular, and can have one or more numbers,

[0104] As shown in the drawing, the size of the outer end portion may be larger than the size of the portion connected to the mounting surface, so that it may be a hook-type fifth hook, or it may be a non-hook-type fifth hook with the same overall size.

[0105] Furthermore, in the modified example within the left dashed line ellipse of Fig. 2 [A], a part of the lower third catch (J3) of the mounting portion (M1) is opened to form a discharge groove (Cg) into which a finger, fingernail, or other tool can be inserted. By inserting a finger or the like into the discharge groove (Cg) and pushing the label (L) upward, the label can be easily separated.

[0106] In the above description, conventionally known techniques related to double packaging containers and labels, etc. are omitted, but those skilled in the art can easily guess, infer, and reproduce them.

[0107] In addition, in explaining the present invention above, a packaging container having a specific shape and structure has been mainly described with reference to the attached drawings, but the present invention can be variously modified, changed, and substituted by those skilled in the art, and such modifications, changes, and substitutions should be interpreted as falling within the scope of protection of the present invention.

6. In paragraph 1 or 2, The above mounting part further has a third or fourth catch on the lower or upper side, A packaging container characterized in that the concave surface of the above-mentioned mounting portion has a left-right curve shape, an up-down curve shape, or both.

7. In paragraph 1 or 2, The above mounting part has a central protrusion, and the label is formed hollow to accommodate the protrusion. A packaging container characterized in that the hollow portion corresponds to the shape of the projection and is slightly smaller than the outer end of the projection, so that after joining, the hollow peripheral flange is caught on the additional fifth catch, thereby ensuring the firm fixation of the label mounting portion.
