The present invention relates to a packaging container including an eco-friendly non-bonding label mounting part. The packaging container includes a body connected to a discharge part and forming a storage part, and a non-bonding type label mounting part disposed on the body and including first and second locking protrusions disposed on the left and right sides thereof, whereby, when a label is simply inserted into the concave mounting part without using an existing label coupling method, an end portion of the label is caught by the locking protrusions provided on the left, right, upper, and lower sides of the mounting part or on the left, right, and lower sides of the mounting part due to a restoring force of a film-type label that tends to return to a flat shape, thereby preventing separation and firmly maintaining an inserted and engaged state, and, upon disposal, the label can be easily removed and no foreign substance such as an adhesive remains, thereby allowing only a pure packaging container made of a PET material or the like to be separately discharged.

Description

Packaging container equipped with a non-bonding label mounting section

[0001] The present invention relates to a packaging container having a non-bonding label mounting portion, specifically a synthetic resin packaging container, and more specifically a PET packaging container.

[0002] Specifically, a mounting portion for a label for identifying, describing, manufacturing, trademark, etc. of the contents is provided on the observation surface of the body forming the contents storage portion, so that when a label is simply inserted into the insertion portion without using existing label coupling methods such as attachment methods or heat shrink film methods, the end of the label catches on the left-right, upper-low or left-right, lower-side locking projections of the mounting portion due to the force in which the film-type label attempts to restore itself to a flat shape in the concave insertion portion, thereby preventing separation and maintaining a firmly inserted coupling state.

[0003] When disposing of, labels can be easily removed, and no foreign substances such as adhesives remain, allowing only pure packaging containers made of materials such as PET to be separated and disposed of.

[0004] Furthermore, the invention relates to a packaging container in which the contents can be discharged in their entirety by having a tube connected to a pump or dropper extend to the central part, while the bottom surface of the body is joined through a curved groove and an inward projection, and the lower part of the storage section of the body has a concentration section formed to collect the internal fluid in the central part.

[0005] Numerous technologies related to synthetic resin containers have been presented in the past.

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

[0007] This registered patent comprises: a nozzle portion through which contents are discharged by pressure applied by a user through a discharge port; a pump assembly that discharges the contents according to the pressure applied by the nozzle portion; an inner container including a first receiving portion for receiving the contents and a first rim portion formed above the first receiving portion for receiving and settling at least a portion of the pump assembly; an outer container including a second receiving portion for receiving the inner container and a second rim portion formed above the second receiving portion; and a shoulder portion detachably coupled to the second rim portion of the outer container and, according to the coupling, pressurizes the inner container to securely fix the inner container to the outer container.

[0008] A double container structure consisting of an inner container and an outer container is configured, and by manufacturing the outer container by blow molding, a unique design, volume, and aesthetic appeal through curved surfaces that are not seen in containers manufactured by conventional injection molding can be provided. Furthermore, despite the rich volume, the container thickness can be reduced through blow molding, thereby lowering production costs and process difficulty.

[0009] In addition, there is Patent Registration No. 10-2130150 (June 29, 2020) [Double container with reinforcing function],

[0010] This registered patent relates to a double container that divides the container into an inner container and an outer container and provides a space with an insulating function between the inner container and the outer container, and has a reinforcing function that minimizes deformation of the double container due to heating, strengthens the connection between the inner container and the outer container, and improves heat blocking efficiency.

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

[0012] Furthermore, there is Patent Registration No. 10-2271373 (June 24, 2021) [Double Container],

[0013] This registered patent comprises: a nozzle portion through which contents are discharged by pressure applied by a user through a discharge port; a pump assembly that discharges the contents according to the pressure applied by the nozzle portion; an inner container including a first receiving portion for receiving the contents and a first rim portion formed above the first receiving portion for receiving and settling at least a portion of the pump assembly; an outer container including a second receiving portion for receiving the inner container and a second rim portion formed above the second receiving portion; and a shoulder portion detachably coupled to the second rim portion of the outer container and, according to the coupling, pressurizes the inner container to securely fix the inner container to the outer container, wherein the outer container is made of glass material.

[0014] A double container structure composed of an inner container and an outer container can be constructed, and by composing the outer container with a retaining material, a more luxurious aesthetic can be provided. When the inner container is received within the outer container, a primary connection is performed through the seating rim and anti-rotation protrusion of the inner container and the second rim and anti-rotation groove of the outer container, and additionally, a secondary connection between the inner container and the outer container is performed through the shoulder portion, thereby providing a more robust double connection structure.

[0015] In addition, there is Patent Registration No. 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 component of the double container can be easily separated and combined, and all components forming the container can be recycled.

[0017] The inner container, shawl inner container, shoulder, pump, outer container, and overcap can be easily assembled and disassembled, making it very convenient to use. Furthermore, since all disassembled parts are made of plastic, it offers an excellent recycling effect for all parts.

[0018] However, prior art, including these prior art documents, is unrelated to providing a concentration element at the bottom of the storage section of a packaging container that enables the full discharge of the contents, and is also unrelated to technology for manufacturing entirely from PET material.

[0019] Meanwhile, various non-adhesive label mounting methods have been proposed in the past.

[0020] For example, there is Patent Registration No. 10-1038371 (Registration Date May 25, 2011) [In-mold label, in-mold container including the same, and method of manufacturing the same],

[0021] This registered patent describes an in-mold label formed in the shape of an arc-shaped band, wherein the lower portion of the in-mold label includes a cut portion formed by cutting off a part of the lower portion,

[0022] The in-mold container comprises: a container body including a main body side and a main body bottom portion that is folded and extended from the main body side; and an in-mold label formed on the container body, wherein the in-mold label includes a label cutting portion formed by cutting a part of the label bottom portion at the label bottom portion of the in-mold label, and the label bottom portion is positioned on the main body fold portion corresponding to the shape of the main body fold portion.

[0023] As such, by using an in-mold label processed to fit the external shape of the in-mold container, the container can be molded into various shapes to improve container design. Additionally, since the in-mold label can be formed on parts of the in-mold container that are susceptible to impact or are weak against impact, the impact resistance of the in-mold container can be improved. Furthermore, defects such as overlapping and lifting of the in-mold label can be reduced during the manufacturing of the in-mold container. Moreover, by optimizing vacuum control, the manufacturing yield of the in-mold container can be improved, and the handling safety of the in-mold container can be enhanced by reducing sharp parts of the in-mold container.

[0024] Next, there is Patent Registration No. 10-1716092 (Registration Date: March 7, 2017 [Method for manufacturing a pressure vessel having an in-mold label and a three-dimensional shape],

[0025] This registered patent relates to a pressure vessel and a method for manufacturing the same, wherein a three-dimensional shape can be formed on the outer surface of an in-mold labeled pressure vessel through a blowing operation on a preform.

[0026] Since it is possible to impart three-dimensional shapes, colors, and textures to pressure vessels, it helps to enhance the advertising and promotional effects of products using such pressure vessels, and provides the advantage of being able to realize various three-dimensional shapes by forming various types of patterns, letters, designs, numbers, and pictures inside the mold cavity.

[0027] However, the two aforementioned conventional patents are specific to in-mold technology and do not possess significant technical differentiation or advantages; furthermore, they are unrelated to technology that provides the convenience of separating labels and packaging containers.

[0028] Furthermore, there is Patent Registration No. 10-2522450 (Registration Date April 12, 2023) [Label Structure for Beverage Container],

[0029] This registered patent relates to a label structure that is easily detachable by being attached in a non-adhesive manner and fitted into the neck of a beverage container.

[0030] The label structure gradually increases in diameter from the top surface to the bottom surface, and is formed in a cone shape with the top and bottom surfaces open.

[0031] It can be attached to beverage containers using a so-called non-adhesive method that simply slides into the neck of the bottle, and since it can be separated from the container by a simple peeling operation when recycling discarded beverage containers, it has the advantage of improving work efficiency in beverage container recycling.

[0032] However, the label of this registered patent has poor adhesion to the packaging container, making it prone to easy separation or damage during production, transfer, storage, and post-purchase handling, resulting in low commercial viability or reliability.

[0033] In addition, there is Patent Publication No. 10-2023-0140057 (Publication Date: October 06, 2023) [Easy-to-separate label for drinking water containers],

[0034] This disclosed patent relates to a label that facilitates the recycling of a drinking water container by configuring the label, which is closely bonded to the outer surface of the drinking water container, to be easily separated and removed from the container.

[0035] The label is made of a heat-shrink film material and has a perforation formed on the outer surface of the drinking water container, and is configured in such a way that anyone, regardless of age or gender, can easily grasp it with their fingers and easily separate and remove it with a weak force, thereby having the advantage of allowing the label to be removed and disposed of immediately after using the drinking water container.

[0036] However, this disclosed patent is merely an improvement to the perforation line as part of a heat-shrink film label.

[0037] Accordingly, the present invention aims to provide a double packaging container in which a curve is attached to the bottom surface of the body to ensure uprightness, and the lower groove of the body and the inward projection of the curve are coupled, and a concentration portion is formed at the bottom of the storage portion of the body to collect internal fluid in the central portion, so that a tube connected to a pump or dropper extends to the concentration portion to discharge the entire contents.

[0038] Furthermore, the present invention aims to provide a packaging container in which a plurality of elastic cutouts are spaced apart and formed on the upper part of the bend, thereby improving the speed and firmness of joining with the body.

[0039] Furthermore, the present invention aims to provide a packaging container in which a base supporting the lower outer surface of the concentrated portion of the body is formed at the center of the bottom surface of the base, so that there is no problem with durability even when the body is manufactured in a maximally thin shape.

[0040] In addition, the present invention aims to provide a packaging container equipped with a non-bonding label mounting part that does not use adhesive by introducing a non-bonding type label mounting part including left and right first and second locking projections on the body.

[0041] Furthermore, the present invention aims to provide a packaging container having a non-bonding label mounting portion, wherein the mounting portion further comprises third and fourth locking projections on the lower or upper part to further improve the stability of the label mounting state.

[0042] Furthermore, the present invention aims to provide a packaging container equipped with a non-bonding label mounting portion, wherein the first to fourth stopper portions of the present invention have a structure that does not protrude radially further than the outer surface of a radially symmetric or asymmetric body centered on the discharge portion, thereby maintaining a smooth appearance and enabling protection of the label mounting portion and the label provided therein.

[0043] In addition, the present invention aims to provide a packaging container equipped with a non-bonding label mounting part, wherein the contact surface of the back of the label of the mounting part is a concave surface, thereby ensuring the stability of the bonded state of the mounted label.

[0044] Furthermore, the present invention aims to provide a packaging container equipped with a non-bonding label mounting portion that ensures product design diversity by configuring various label mounting portions, wherein the concave surface is in the form of a left-right curve, an up-down curve, or both.

[0045] To achieve the above objectives, the packaging container according to the present invention

[0046] A body connected to a discharge section and equipped with a storage section; and

[0047] Includes a bend that is coupled to the bottom surface of the body;

[0048] The above body has a groove formed in the lower part, and

[0049] The above curved groove has an inward projection formed thereon that engages with it, and

[0050] At the bottom of the storage section of the above body, a concentration section is formed to collect the internal fluid in the central section.

[0051] Also, in a packaging container equipped with an upright base according to the present invention

[0052] A plurality of elastic incisions are spaced apart and formed on the upper part of the above-mentioned curve, and

[0053] It is preferable that a base supporting the lower outer surface of the concentrated portion of the body is formed in the center of the bottom surface of the above-mentioned base.

[0054] Meanwhile, the packaging container according to the present invention is provided with a non-bonding label mounting portion, in this case

[0055] The body is provided with a non-bonding type label mounting part including left and right first and second locking tabs, and

[0056] This mounting part is characterized by having a recessed structure that does not protrude further in a radial direction than the outer surface of a radially symmetric or asymmetric body centered on the discharge part.

[0057] Also, in a packaging container equipped with a non-bonding label mounting portion according to the present invention

[0058] The above mounting part further comprises a third and fourth locking projection on the lower or upper part, and

[0059] The contact surface of the back of the label of the above-mentioned mounting part is a concave surface, and

[0060]

[0061] The above concave surface may be in the shape of a left-right curve, an up-down curve, or both.

[0062] It is preferable that the above-mentioned stopper has a structure that does not protrude radially further than the outer surface of the radially symmetric or asymmetric body centered on the discharge portion.

[0063] The packaging container equipped with an upright foot according to the present invention ensures uprightness by having the foot attached to the bottom surface of the body, and the lower groove of the body is coupled with the inward projection of the foot. A concentration groove is formed at the bottom of the storage portion of the body to collect internal fluid in the central portion, so that a tube connected to a pump or dropper extends to the concentration groove, allowing for the discharge of the entire contents. Additionally, a plurality of elastic cutouts are spaced apart on the upper part of the foot to improve the speed and firmness of the connection with the body. Furthermore, a base is formed at the center of the bottom surface of the foot to support the lower outer surface of the concentration groove of the body, so there is no problem with durability even if the body is manufactured to be as thin as possible. Moreover, by manufacturing the body and foot using PET material, which is a synthetic resin, particularly blow molding which has superior productivity compared to injection molding, productivity can be improved and the recycling rate can be increased. It is suitable for storing cosmetics, beverages, liquid detergents, shampoos, rinses, etc.

[0064] Meanwhile, a packaging container equipped with a non-bonding label mounting section is environmentally friendly as it does not use adhesives by introducing a non-bonding label mounting section that includes first and second locking tabs on the left and right sides of the body. Furthermore, the stability of the label mounting state can be further enhanced by additionally providing third and fourth locking tabs on the lower or upper side of the mounting section. Moreover, the first to fourth locking tabs have a structure that does not protrude radially from the outer surface of the body, which is radially symmetric or asymmetrical with respect to the discharge section, thereby maintaining a smooth appearance and enabling protection of the label mounting section and the label provided thereon. Additionally, the contact surface of the back of the label on the mounting section is a concave surface, ensuring the stability of the bonded state of the mounted label. Furthermore, the concave surface can be in the form of a left-right curve, an up-down curve, or both, allowing for the configuration of various label mounting sections. Ultimately, a label mounting section for identifying, describing, manufacturing, trademarks, etc., of the contents is provided on the observation surface of the body forming the contents storage section. Consequently, without using conventional label bonding methods such as attachment methods or heat-shrink film methods, simply inserting the label into the insertion section causes the film-type label to attempt to restore to a flat form within the concave insertion section. By force, the end of the label catches on the left, right, upper, and lower sides or the left and right lower sides of the mounting part, preventing separation and maintaining a firmly inserted and coupled state. When disposing of the item, the label can be easily removed, and no foreign substances such as adhesive remain, so that only the pure packaging container, such as PET material, can be separated and disposed of.
