Description

Connectable container and container assembly including the same

[0001] The present disclosure relates to a combinable container and a container assembly comprising the same.

[0002] Among various types of containers, there are those made of deformable materials designed to store fluids (liquids, gels, pastes, etc.) or powders for convenient use, and which include a spout at the opening. These containers are used for a wide range of products, including beverages, food, cosmetics, and detergents, and are designed to allow for easy pouring of the contents. Therefore, unlike conventional containers with fixed shapes (such as glass, rigid plastic, or ceramics), these containers are made of deformable materials and have a flat shape, allowing the user to easily dispense the contents by applying pressure. However, such containers present the following problems during storage and use.

[0003] First, due to its shape, the container cannot be stood upright and must be stored lying down with the wider side facing down. This results in a large surface area in contact with contaminated or damp surfaces, which is unhygienic. Additionally, storing it horizontally can cause the container to tear or deform due to collisions with or pressure from other objects, and the contents may shift towards the opening, causing inconvenience for the user when holding the container to dispense the contents. Furthermore, when storing multiple containers, the movement of the contents causes the shapes to become uneven, resulting in unstable stacking that makes organization and storage difficult.

[0004] The information described above disclosed in the background technology of this invention is intended only to enhance understanding of the background of the present invention and may therefore include information that does not constitute prior art.

[0005] The present disclosure is intended to solve the aforementioned problems and can provide a container and a container assembly including the same, which can be used to store and use multiple containers by connecting them to each other and standing them upright by including a structure that can be connected to each other.

[0006] However, the technical problems that the embodiments of the present disclosure aim to solve are not limited to those described above, and other unmentioned problems can be clearly understood by a person skilled in the art from the description of the invention below.

[0043] FIG. 1 shows a container (1) according to embodiments of the present disclosure, FIG. 2 shows an exploded view of FIG. 1, FIG. 3 shows a port (10) according to embodiments of the present disclosure, FIG. 4 shows a cross-section according to IV-IV' of FIG. 3, FIG. 5 shows a cap (140) according to embodiments of the present disclosure, FIG. 6 shows a state in which containers (1) according to embodiments of the present disclosure are joined together, FIG. 7 shows a container assembly (2) in which containers (1) of FIG. 6 are joined together, FIG. 8 shows a cross-section of the port (10) of FIG. 7, and FIG. 9 shows a container assembly (2) in which containers (1) according to embodiments of the present disclosure are joined together.

[0044] A container (1) according to embodiments of the present disclosure can receive and dispense contents. A container (1) can be combined with another container (1) to form a container assembly (2). When combined with another container (1), the container (1) can be maintained upright on a floor surface without other auxiliary devices or without being held by another user. For example, the container (1) may be a spout pouch. The container (1) may be used for cosmetics, food, beverages, pharmaceuticals, etc.

[0045] A container (1) according to embodiments of the present disclosure comprises a housing (20) for receiving contents and a port (10) connected to the housing (20), wherein the port (10) comprises a main body portion (110), a connecting portion (130) extending from below the main body portion (110) and inserted into an opening (201) of the housing (20), an inlet portion (120) extending from above the main body portion (110) and communicating with the main body portion (110) and the connecting portion (130), and a cap (140) covering the inlet portion (120), wherein the main body portion (110) has a shape corresponding to the plug (114) and includes a channel (111) on the opposite side of the plug (114) in a first direction intersecting with a second direction which is the width direction of the housing (20), and wherein the container (1) is such that the plug (114) is inserted into the channel (111) of another container (1) or A plug (114) of another container (1) can be inserted into the channel (111) to enable combination with another container (1).

[0046] A container assembly (2) according to embodiments of the present disclosure is a container assembly (2) comprising a plurality of containers (1), a housing (20) for receiving contents, and a port (10) connected to the housing (20). The port (10) comprises a main body portion (110), a connecting portion (130) extending from below the main body portion (110) and inserted into an opening (201) of the housing (20), an inlet portion (120) extending from above the main body portion (110) and communicating with the main body portion (110) and the connecting portion (130), and a cap (140) covering the inlet portion (120). The main body portion (110) has a plug (114) and a channel (111) having a shape corresponding to the plug (114) and a first direction that intersects the second direction, which is the width direction of the housing (20), on the opposite side of the plug (114). The container (1) is such that the plug (114) is of another container (1). A plug (114) of another container (1) may be inserted into the channel (111) or inserted into the channel (111) to be combined with another container (1).

[0047] In another embodiment, the container assembly (2) may further include a base unit that rests on the bottom surface in addition to a plurality of containers (1). The base unit may have a flat bottom surface that contacts the bottom surface and a top surface that includes one or more channels or plugs. The container (1) may be coupled to the base unit by inserting the plug (114) of the container (1) into the channel (111) of the base unit, or by inserting the plug of the base unit into the channel (111) of the container (1). The self-standing stability of the container assembly (2) may be further enhanced by the flat bottom surface of the base unit. The base unit may include a rubber pad or an adsorption pad on the bottom surface for anti-slip purposes.

[0048] A container (1) according to embodiments of the present disclosure may include a port (10) and a housing (20).

[0049] First, the housing (20) is described as being capable of containing contents inside. The housing (20) may include a deformable material so that the user can press or deform the housing (20) to discharge the contents out of the port (10). For example, the housing (20) may include a single-layer film or a multi-layer film structure comprising one or more of polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), nylon or polyamide (PA), aluminum foil, or ethylene vinyl alcohol copolymer (EVOH). In addition, the housing (20) may include a flexible and deformable material depending on the characteristics of the contents and storage conditions.

[0050] The contents contained in the housing (20) may include food, beverages, cosmetics, pharmaceuticals, health supplements, and other industrial or household products. For example, the contents contained in the housing (20) may include liquids or powders of various viscosities or small-sized pellets. The housing (20) may include an internal space for containing these contents.

[0051] The housing (20) can be connected to the port (10). The housing (20) may include an opening (201) at the top that is connected to the port (10). For example, the housing (20) may be formed by bonding two or more thin films together and may include an opening (201) at the top to which the port (10) is connected. The port (10) (e.g., the connecting part (130) of the port (10)) is inserted into the opening (201), and the opening (201) may communicate with the internal space of the housing (20).

[0052] The housing (20) may have a flat shape or at least a shape with a narrow surface that contacts the bottom. For example, as shown in FIG. 1, the housing (20) may have a thin pouch shape that cannot be stood upright on the bottom surface by itself. The container (1) according to the embodiments of the present disclosure may be combined with another container (1) so that the housing (20) of this shape can also be stood upright on the bottom.

[0053] By combining multiple containers (1) and maintaining them upright on the bottom surface, the wide surface of the housing (20) can be prevented from coming into contact with the bottom surface. Therefore, the contact area with the contaminated or wet bottom surface is significantly reduced, allowing for hygienic storage of the contents. This is particularly advantageous for containers (1) that hold contents for which hygienic management is important, such as cosmetics, food, and pharmaceuticals.

[0054] In addition, since multiple containers (1) are combined and stored in an upright state, the housing (20) can be prevented from being torn or deformed by collision with other objects or load when stored lying down. Therefore, the durability of the housing (20) is improved and leakage of the contents can be prevented.

[0055] In addition, when the container (1) is in an upright position, the contents accumulate at the bottom of the housing (20) due to gravity, allowing for immediate dispensing when the user turns the container (1) over to dispense the contents. This eliminates the inconvenience that occurs during the dispensing process when the contents are stored lying down and shift toward the inlet (120). Since multiple containers (1) are combined and maintained in a stable upright position on the floor, the user can detach the cap (140) with one hand and apply the contents using the applicator (141). That is, in the past, the user had to hold the container (1) with one hand and detach the cap (140) with the other hand, but according to the present disclosure, since only the cap (140) needs to be detached while the container (1) is standing upright on the floor, one-hand operation is possible, thereby improving user convenience.

[0056] In another embodiment, the housing (20) may have a gusset-type pouch, a stand-up pouch, or a combination thereof, in addition to the flat pouch shape described above. For example, the housing (20) may have a stand-up pouch shape including a gusset at the bottom, and may be additionally connected to another container (1) by the plug (114) and channel (111) of the port (10). By doing so, it is possible to stand independently as a single container (1), and the stability of standing independently can be further improved by connecting with another container (1).

[0057] The port (10) can be connected to the housing (20) as a part from which the contents of the container (1) are discharged. The port (10) is connected to the opening (201) of the housing (20), and the contents can be discharged out of the port (10) by the user pressing the housing (20) or by turning the port (10) downward. The port (10) can be connected to the port (10) of another container (1). For example, as shown in FIG. 7, the port (10) contained in one container (1) can be connected to each of the ports (10) contained in one or more other containers (1). By doing so, multiple containers (1) can be combined with each other. With the ports (10) connected to each other, the containers (1) can be stood upright on the floor. Therefore, the user can use the container (1) by placing it on the floor and removing the cap (140) without having to hold the container (1) while using it. In addition, multiple containers (1) can be stored upright on the floor surface instead of lying down.

[0058] The port (10) may include a passage (101). As shown in FIG. 4, the passage (101) may include a first passage (118) of the main body part (110) described later, a second passage (121) of the inlet part (120), and a third passage (133) of the connecting part (130). The passage (101) communicates with the opening (201) of the housing (20), and contents may be discharged to the outside of the container (1) through the passage (101). Alternatively, an applicator (141) of the cap (140) may be inserted into the passage (101).

[0059] The port (10) may include a main body (110), an inlet (120), a connection (130), and a cap (140).

[0060] The main body (110) can support other components of the port (10) (e.g., the inlet part (120), the connection part (130), and the cap (140)). The main body (110) is located between the inlet part (120) and the connection part (130) and can be connected to the main body (110) of another port (10). For example, as shown in FIG. 3, the inlet part (120) may be located on the upper surface of the main body (110) and the connection part (130) may be located on the lower surface.

[0061] The main body (110) may include a channel (111), a first guide (112), an inner groove (113), a plug (114), an outer projection (115), an upper support piece (116), a lower support piece (117), a first passage (118), and a second guide (119).

[0062] The channel (111) is an empty space formed inside the main body (110), and a plug (114) of a port (10) contained in another container (1) can be inserted into the channel (111). For example, as shown in FIG. 3, the channel (111) is formed inside the main body (110), and a plug (114) contained in a port (10) of another container (1) can be inserted therein. The channel (111) and the plug (114) have corresponding shapes and sizes and can be fitted together. For example, the channel (111) and the plug (114) may have (substantially) the same cross-sectional shape (e.g., the ZX cross-section in FIG. 3). Therefore, when a plug (114) of another container (1) is inserted into a channel (111) of one container (1), the outer surface of the plug (114) comes into contact with the inner surface of the channel (111), so that the ports (10) can be connected to each other. The channel (111) may not be in communication with the passage (101). For example, as shown in FIG. 3, the channel (111) may have a rectangular shape.

[0063] The first guide (112) is located on the inlet side of the channel (111) and can allow the plug (114) to be smoothly inserted into the channel (111). For example, as shown in FIGS. 3 and 4, the first guide (112) may be an inclined surface formed on the inlet side edge of the channel (111). When the plug (114) is inserted into the channel (111), the edge of the plug (114) or the second guide (119) may come into contact with the first guide (112). Thus, the plug (114) and the channel (111) are positioned, and the plug (114) can be stably inserted into the channel (111).

[0064] In this way, the first guide (112) formed on the inlet side of the channel (111) and the second guide (119) formed on the inlet side of the plug (114) have corresponding inclined surfaces, so that when the plug (114) is inserted into the channel (111), it can naturally self-align along the inclined surface. Therefore, even if the user does not have to align the exact positions of the plug (114) and the channel (111) individually, if only the approximate direction is aligned, the plug (114) is guided into the channel (111) by the inclined surfaces of the first guide (112) and the second guide (119), making connection easier.

[0065] An inner groove (113) may be formed on the inner surface of the channel (111). When the plug (114) is inserted into the channel (111), the outer projection (115) of the plug (114) is seated in the inner groove (113), thereby preventing the plug (114) from being dislodged from the channel (111). The inner groove (113) may include one or more inner grooves (113). The number, location, size, and / or shape of the one or more inner grooves (113) may correspond to one or more outer projections (115) formed on the plug (114). As shown in FIGS. 3 and 4, the inner groove (113) may be formed on the inner upper surface and the inner lower surface of the channel (111), respectively.

[0066] The plug (114) is located on the opposite side of the channel (111) and may have a size and / or shape corresponding to the channel (111). For example, as shown in FIGS. 3 and 4, the plug (114) may be on the opposite side of the channel (111) in the thickness direction of the port (10) (or the first direction or the Y-axis direction in FIGS. 3 and 4). The plug (114) extends in the first direction and may be inserted into the channel (111) of the port (10) contained in another container (1). The plug (114) and the channel (111) may be fitted together so that different containers (1) can be joined together. For example, as shown in FIG. 3, the plug (114) may have a rectangular shape. When the plug (114) is inserted into the channel (111), the outer surface of the plug (114) (e.g., the top surface, bottom surface, two sides, and the front surface) may come into contact with the inner surface of the channel (111). When the plug (114) is inserted into the channel (111) of another container (1), the outer surface of the plug (114) may come into contact with the inner surface of the channel (111) of another port (10) to be fitted into the channel (111).

[0067] The plug (114) may have elasticity. The elasticity of the plug (114) may be due to the material, the structure, or a combination thereof. For example, the plug (114) may have elasticity by being formed from a material including polypropylene (PP), polyethylene (PE), polyamide (PA), thermoplastic elastomer (TPE), thermoplastic polyurethane (TPU), or a combination thereof. Alternatively, the plug (114) may have elasticity by a structure comprising a plurality of spaced-apart segments as described below. In this case, since each segment can be deformed independently by the spaced-apart space, it is possible to deform with less force than when the entire plug (114) is formed as a single unit. Therefore, when the plug (114) is inserted into the channel (111) due to the elasticity of the plug (114), the plug (114) is temporarily deformed and then restored, thereby allowing the outer projection (115) or the coupling projection to be stably inserted into the inner groove (113). In addition, due to the elastic restoring force of the plug (114), the outer surface of the plug (114) is in close contact with the inner surface of the channel (111), thereby improving the bonding force between the plug (114) and the channel (111).

[0068] In another embodiment, at least a portion of the plug (114) and / or channel (111) may comprise an elastomer, a thermoplastic elastomer (TPE), or silicone. For example, the entire port (10) may be formed of hard plastic, and a coating layer or overmolding layer of an elastic material may be formed on the inner or outer surface of the plug (114) or channel (111). This improves the grip strength due to the elastic material when the plug (114) and channel (111) are fitted together, thereby increasing the bonding strength. Additionally, the elastic material compensates for the fine gap between the plug (114) and channel (111), preventing rattling during assembly.

[0069] The outer projections (115) are formed on the plug (114) and may have a number, size, and / or shape corresponding to the inner groove (113). When the plug (114) is inserted into the channel (111) and reaches a predetermined position, the outer projections (115) are inserted into the inner groove (113) to prevent the plug (114) from coming out of the channel (111). The outer projections (115) may include one or more outer projections (115). For example, the outer projections (115) may be formed on the upper and lower surfaces of the plug (114), respectively. The combination of the outer projections (115) and the inner groove (113) may prevent the containers (1) from being separated along with the combination of the plug (114) and the channel (111). For example, the outer projections (115) may be hemispherical or dome-shaped.

[0070] In another embodiment, the outer projection (115) may have a wedge shape, serration, arrowhead shape, or triangular cross-sectional shape in addition to a hemispherical or dome shape. For example, if the outer projection (115) is wedge-shaped, the slope in the direction in which the plug (114) is inserted into the channel (111) is gentle and the slope in the direction of exit is steep, so that insertion is easy but resistance to exit can be improved. Also, if the outer projection (115) is serration-shaped, frictional force is increased by a plurality of fine projections, and bonding strength can be improved. The inner groove (113) may have a shape corresponding to the shape of the outer projection (115).

[0071] The main body (110) may include a deformable material. Therefore, when the plug (114) is inserted into the channel (111) and fitted, it may be temporarily deformed by being pressed against the inner surface of the channel (111) by the outer projection (115). Additionally, movement of the plug (114) may be allowed so that the outer projection (115) is inserted into the inner groove (113).

[0072] At this time, as the outer projection (115) passes through the inner surface of the channel (111) and is inserted into the inner groove (113), the deformable material of the main body (110) is temporarily deformed and then restored, thereby providing a click sensation (tactile feedback) to the user. Thus, the user can tactilely perceive whether the connection between the plug (114) and the channel (111) has been correctly completed.

[0073] The distance from the tip of the plug (114) to one or more outer protrusions (115) may be equal to the distance from the inner end surface of the channel (111) to the inner groove (113). That is, the distance from the end surface of the plug (114) to the outer protrusion (115) in the first direction in which the plug (114) is inserted into the channel (111) may be equal to the distance from the inner end surface of the deepest part of the channel (111) (or the side surface of the first passage (118)) to the inner groove (113). Therefore, when a user inserts the plug (114) of one container (1) into the channel (111) of another container (1), the tip of the plug (114) comes into contact with the inner end surface of the channel (111), and the outer protrusion (115) is also inserted into the inner groove (113). Therefore, the user can seat the outer projection (115) in the inner groove (113) simply by inserting the plug (114) all the way into the channel (111), without needing to finely adjust the insertion depth of the plug (114).

[0074] As such, since the distance from the tip of the plug (114) to the outer projection (115) is the same as the distance from the inner cross-section of the channel (111) to the inner groove (113), the outer projection (115) is automatically seated in the inner groove (113) with only a single action of the user inserting the plug (114) all the way into the channel (111). Therefore, a correct coupling state can be achieved without separate visual confirmation or precise position adjustment, thereby improving user convenience.

[0075] In another embodiment, one or more outer protrusions (115) may be formed on the front end surface of the plug (114). For example, as shown in FIG. 4, one or more outer protrusions (115) may be formed on the cross-section in the first direction. Additionally, one or more inner grooves (113) may be formed on the inner cross-section of the channel (111) to correspond to one or more outer protrusions (115). These one or more outer protrusions (115) and inner grooves (113) allow the channel (111) and the plug (114) to be easily positioned and increase the fastening force between the channel (111) and the plug (114).

[0076] The upper support piece (116) may extend from the upper surface of the main body (110) in the width direction of the port (10) (or the X-axis direction of FIG. 3 or the second direction). For example, as shown in FIG. 3, the upper support piece (116) may extend from the upper surface of the main body (110) in the second direction and may protrude further than the side of the main body (110). The upper support piece (116) may allow the user to carry the container (1) by gripping the upper support piece (116) in addition to gripping the housing (20) when gripping the container (1).

[0077] The lower support piece (117) may extend from the lower surface of the main body (110) in the width direction of the port (10) (or the X-axis direction of FIG. 3 or the second direction). For example, as shown in FIG. 3, the lower support piece (117) may extend from the upper surface of the main body (110) in the second direction and may protrude further than the side of the main body (110). The lower support piece (117) may come into contact with the upper end of the connecting part (130). The lower support piece (117) may allow the main body (110) to be supported by the connecting part (130), thereby preventing the main body (110) and the port (10) containing it from moving. As shown in FIG. 3, the lower support piece (117) may protrude further in the second direction than the upper support piece (116).

[0078] The upper support member (116) and the lower support member (117) may be spaced apart in the height direction of the port (10) (or in the Z-axis direction or third direction of FIG. 3). For example, as shown in FIG. 3, there may be a gap between the upper support member (116) and the lower support member (117). A support frame, etc., may be positioned in the gap to store and organize the container (1), or a user may insert their finger to grip the container (1).

[0079] Additionally, the gap between the upper support piece (116) and the lower support piece (117) can be utilized for various purposes. For example, a support frame, a hanger, or a clip can be positioned in the gap to hang the container (1) on a wall or display stand for storage. Additionally, a band or similar device to bind multiple containers (1) together can be passed through the gap to transport the containers (1) collectively.

[0080] The first passage (118) is an internal passage of the main body (110) and can communicate with the second passage (121) of the entrance part (120) and the third passage (133) of the connecting part (130). For example, as shown in FIG. 4, the first passage (118) may be below the second passage (121) and above the third passage (133).

[0081] The second guide (119) is located on the inlet side of the plug (114) and can allow the plug (114) to be smoothly inserted into the channel (111). For example, as shown in FIGS. 3 and 4, the second guide (119) may be an inclined surface formed on the inlet side edge of the plug (114). The second guide (119) may have a shape corresponding to the first guide (112). When the plug (114) is inserted into the channel (111), the second guide (119) may come into contact with the first guide (112). Thus, the plug (114) and the channel (111) are positioned, and the plug (114) can be stably inserted into the channel (111).

[0082] In another embodiment, the main body (110) may further include a release part for easily releasing the connection between the plug (114) and the channel (111). For example, the release part may be a button or lever formed on the outer surface of the main body (110). When a user presses the release part, the inner surface of the channel (111) is deformed in a direction separated from the plug (114), causing the outer projection (115) to detach from the inner groove (113) and making it easier to pull out the plug (114). Alternatively, the release part may be a groove formed at the base of the plug (114), providing a lever point through which a user can insert a fingernail or a tool to lift the plug (114) from the channel (111).

[0083] In another embodiment, a sealing member (e.g., an O-ring, a gasket, or a sealing lip) may be installed on the outer surface of the plug (114) or on the inner surface of the channel (111). The sealing member can prevent external moisture or foreign matter from penetrating through the joint between the plug (114) and the channel (111). This is particularly advantageous when the container (1) is used in a humid environment, such as a bathroom or kitchen.

[0084] In another embodiment, the main body (110) may include a plurality of plugs (114) on one side facing the first direction and / or a plurality of channels (111) on the opposite side. For example, two plugs (114) spaced apart in the second or third direction may be formed on one side of the main body (110), and two channels (111) corresponding to the opposite side may be formed. By doing so, the containers (1) can be joined with a wider contact area, and the stability of the connection can be further improved.

[0085] In another embodiment, the plug (114) and the channel (111) may be positioned eccentrically from the center of the height direction (third direction) or width direction (second direction) of the main body (110). For example, the plug (114) may be positioned eccentrically on the upper part of the main body (110), and the channel (111) may be positioned eccentrically on the upper part of the main body (110) to correspond thereto. By doing so, a fool-proof structure can be implemented that allows the plug (114) and the channel (111) to be connected in only one direction. Thus, it is possible to prevent the user from connecting the container (1) in the wrong direction.

[0086] In another embodiment, the main body (110) may include additional plugs and / or channels that can be combined with other containers (1) in the first direction as well as in the second or third direction. For example, plugs (114) and channels (111) may be formed on both sides of the first direction of the main body (110), and additionally, auxiliary plugs and auxiliary channels may be formed on both sides of the second direction of the main body (110). By doing so, containers (1) can be connected in the first direction (thickness direction) and the second direction (width direction) to form a container assembly in a two-dimensional arrangement. Thus, a more stable self-standing structure and large-area display are possible.

[0087] In another embodiment, the port (10) may include multiple regions of different materials. For example, the main body (110) of the port (10) may be formed of a rigid plastic such as polypropylene (PP) or high-density polyethylene (HDPE), and a thermoplastic elastomer (TPE) may be integrally formed on the contact surface of the plug (114) or channel (111) by co-injection or insert injection. This ensures that the overall rigidity of the port (10) is maintained, while providing an elastic adhesion force and vibration absorption effect at the joint portion of the plug (114) and channel (111).

[0088] The inlet portion (120) is located above the main body portion (110) and can be connected to a cap (140). For example, as shown in FIG. 2, the inlet portion (120) can extend upward from the upper surface of the main body portion (110) (or in the Z-axis direction of FIG. 2 or in a third direction). The inlet portion (120) may be hollow inside so that contents can move. The inlet portion (120) communicates with the main body portion (110) and the connecting portion (130), and contents can flow out from the housing (20), pass through the connecting portion (130) and the main body portion (110), and be discharged to the outside through the inlet portion (120). A cap (140) may be detachably connected to the inlet portion (120). For example, the inlet portion (120) may have a hollow cylindrical shape.

[0089] The entrance portion (120) may include a second passage (121) and a screw thread (122).

[0090] The second passage (121) is partitioned by the inner surface of the entrance portion (120) and may be a passage through which contents move. The second passage (121) may be connected to the first passage (118) of the main body portion (110).

[0091] The screw thread (122) is on the outer surface of the inlet portion (120) and can be coupled with the screw thread of the cap (140).

[0092] In another embodiment, the connection between the cap (140) and the inlet (120) may be made by a snap-fit ​​connection, a bayonet connection, or a friction fit connection, in addition to a threaded connection. For example, an annular projection may be formed on the inner surface of the cap (140) and an annular groove may be formed on the outer surface of the inlet (120), so that when the cap (140) is pressed against the inlet (120), the annular projection is fitted into the annular groove, thereby creating a snap-fit ​​connection. This allows for faster attachment and detachment of the cap (140), thereby improving convenience for the user when using multiple containers (1) sequentially.

[0093] The connecting portion (130) is located below the main body portion (110) and can be connected to the housing (20). For example, as shown in FIG. 2, the connecting portion (130) can extend downward from the bottom surface of the main body portion (110) (for example, in the Z-axis direction of FIG. 2). The connecting portion (130) may have a convex shape facing both sides of the housing (20) (for example, the front and rear sides in the Y-axis direction of FIG. 2 or both sides in the first direction). Thus, the contact area between the connecting portion (130) and the housing (20) can be widened so that the port (10) is firmly connected to the housing (20), and the connecting portion (130) can be subjected to uniform stress to prevent deformation or damage.

[0094] Since the connecting portion (130) has a convex shape facing both sides of the housing (20), the stress applied to the connection portion between the port (10) and the housing (20) can be distributed over a wide area. Therefore, concentrated stress is prevented at the connection portion during the process of a user pressurizing the housing (20) to dispense contents or transporting the container (1), thereby preventing separation or damage to the port (10) and the housing (20).

[0095] The connecting part (130) is inserted into the opening (201) of the housing (20) and can be connected to the housing (20) through heat fusion, ultrasonic welding, adhesive attachment, etc. After all or part of the connecting part (130) is inserted into the opening (201), the opening (201) can be in close contact with the connecting part (130). The opening (201) can be in communication with the passage (101) of the port (10).

[0096] The connecting portion (130) may include a plurality of protrusions (131) and grooves (132). As shown in FIG. 3, the plurality of protrusions (131) may be spaced apart in the height direction of the connecting portion (130) (e.g., front and back sides in the Y-axis direction of FIG. 3) and in the Z-axis direction of FIG. 3. A groove (132) may be formed between two adjacent protrusions (131). The plurality of protrusions (131) and grooves (132) can increase the contact area between the housing (20) and the connecting portion (130) so that the port (10) can be firmly connected to the housing (20).

[0097] The cap (140) can open and close the inlet (120) to control the discharge of contents from the inlet (120). The cap (140) can be detachably connected to the inlet (120). For example, the cap (140) may include a thread on its inner surface corresponding to the thread (122) of the inlet (120) and may be connected to the inlet (120).

[0098] As shown in FIG. 5, the cap (140) may further include an applicator (141). The applicator (141) extends downward from the inner surface of the cap (140) and may have contents applied or impregnated at its end. With the cap (140) connected to the inlet (120), the applicator (141) may be inserted into the housing (20). The user may detach the cap (140) from the inlet (120) to directly discharge contents to the outside through the inlet (120) or apply contents to a desired location using the applicator (141) of the cap (140).

[0099] In another embodiment, an identification means indicating the type of contents, expiration date, order of use, etc., may be formed on the outer surface of the main body (110) or cap (140) of the port (10). The identification means may include, for example, color coding, embossed or engraved characters, symbols, numbers, or braille. In a container assembly (2) in which a plurality of containers (1) are combined, the user can quickly identify the container (1) containing the desired contents by means of the identification means of each container (1). For example, in a skincare routine, when containers (1) containing toner, serum, lotion, etc., are combined, the correct container (1) according to the order of use can be selected by means of the identification means.

[0100] The following describes the state in which a container (1) is connected according to embodiments of the present disclosure.

[0101] FIG. 6 shows two containers (1) according to embodiments of the present disclosure. The user can position the plug (114) of one container (1) so that it faces the channel (111) of the other container (1).

[0102] Next, the plug (114) of one container (1) is inserted into the channel (111) of another container (1). FIG. 7 shows the state in which two containers (1) are combined with each other. FIG. 8 shows the port (10) in the state in which two containers (1) are combined with each other. With the plug (114) inserted into the channel (111), at least one of the front surface, top surface, bottom surface, and both sides of the plug (114) may come into contact with the inner surface of the channel (111). The outer projection (115) of the plug (114) may be inserted into the inner groove (113) of the channel (111). As shown in FIG. 7, the two containers (1) are combined with each other and can be maintained in an upright position on the floor. The user can remove the cap (140) of the container (1) to be used and dispense the contents. The direction in which the container (1) is joined may be parallel to the thickness direction of the container (1) (e.g., the Y-axis direction or the second direction in FIG. 7 and FIG. 8). For example, the direction in which the container (1) is joined may be the first direction that intersects (or is perpendicular to) the second direction. Thus, not only can housings (20) having a shape that is thin in the thickness direction relative to the width direction be arranged more densely, but multiple containers (1) can also be stably erected.

[0103] In this way, the containers (1) are combined in a first direction that intersects with the second direction, which is the width direction of the housing (20), so that the flat-shaped housings (20) are densely stacked in the thickness direction. Therefore, more containers (1) can be stored in the same space, thereby maximizing space utilization efficiency in display stands, storage spaces, etc.

[0104] Although only two containers (1) are shown in FIG. 6-8, the number of containers (1) to be combined may be three or more. For example, as shown in FIG. 9, the channel (111) and plug (114) of a port (10) contained in one container (1) can be combined with the plug (114) of a port (10) contained in another container (1) and the channel (111) of a port (10) contained in another container (1).

[0105] FIG. 10 shows channels (111A, 111B, 111C, 111D, 111E) and plugs (114A, 114B, 114C, 114D, 114E) according to embodiments of the present disclosure. FIG. 10 shows a cross-section viewed, for example, from a first direction.

[0106] FIG. 10(a) shows an embodiment in which the channel (111A) and the plug (114A) have a square cross-section. Inner grooves (113A) may be formed on each of the four inner sides of the channel (111A), and outer protrusions (115A) may be formed on each of the four outer sides of the plug (114A).

[0107] FIG. 10(b) illustrates an embodiment in which the channel (111B) and the plug (114B) have an H-shaped cross-section. For example, the channel (111B) may include a plurality of (e.g., two) vertical openings (1111B) that are long in the height direction (e.g., the Z-axis direction in FIG. 10) and one or more (e.g., one) horizontal openings (1112B) that connect the plurality of vertical openings (1111B). Additionally, the plug (114B) may also have a shape corresponding to the channel (111B). The channel (111B) may include a plurality of insertion protrusions (102B) formed between the plurality of vertical openings (1111B). Accordingly, multiple insertion protrusions (102B) located between multiple vertical openings (1111B) of the channel (111B) are respectively inserted into the upper and lower grooves of the plug (114B), so that the channel (111B) and the plug (114B) can be more firmly connected. The inner groove (113B) is formed on the upper and lower sides of the horizontal opening (1112B) and on both sides of the vertical opening (1111B), respectively, and the outer protrusion (115B) can be formed to correspond to the inner groove (113B). For example, at least some of the multiple outer protrusions (115B) can be formed on the surface facing the insertion protrusion (102B) of the plug (114B). For example, as shown in FIG. 10(b), the outer projection (115B) may be formed on the upper and lower surfaces of the plug (114B), respectively, so as to face the insertion projection (102B). Thus, the fastening force between the insertion projection (102B) and the plug (114B) inserted between the plurality of vertical openings (1111B) can be further increased. Alternatively, the outer projection (115B) may be formed on the inner surface corresponding to the vertical opening (1111B) of the plug (114B), respectively, so as to face the insertion projection (102B).

[0108] In this way, when the H-shaped cross-section channel (111B) and the plug (114B) are combined, the insertion projection (102B) formed between the multiple vertical openings (1111B) is inserted into the corresponding groove of the plug (114B), thereby preventing the plug (114B) from rotating within the channel (111B). Accordingly, the relative positional relationship between the combined containers (1) is stably maintained, thereby improving the structural stability of the container assembly (2).

[0109] FIG. 10(c) illustrates an embodiment in which the channel (111C) and the plug (114C) have cross-shaped cross-sections. For example, the channel (111C) may have an opening shape extending in the height direction (or third direction) and the width direction (or second direction). Additionally, the plug (114C) may also have a shape corresponding to the channel (111C). Thus, the contact area between the plug (114C) and the channel (111C) is widened, allowing the channel (111C) and the plug (114C) to be more firmly connected. The inner groove (113C) is formed on the upper, lower, left, and right sides of the channel (111C), respectively, and the outer projection (115C) may be formed to correspond to the inner groove (113C). In this way, when the cross-shaped cross-section channel (111C) and the plug (114C) are combined, the contact area between the plug (114C) and the channel (111C) is secured in both the height direction (third direction) and the width direction (second direction), thereby improving resistance to external forces in multiple directions. Therefore, the container assembly (2) can maintain a more stable combined state against external shocks or vibrations.

[0110] FIG. 10(d) illustrates an embodiment in which the channel (111D) and the plug (114D) have a circular cross-section. For example, the plug (114D) may have a cylindrical shape, and the channel (111D) may also have a corresponding shape. Thus, the plug (114D) may not have corners on its outer surface, allowing it to be inserted more smoothly into the channel (111D). The plug (114D) may include a plurality of outer protrusions (115D) on its outer surface. The channel (111D) may include a plurality of inner grooves (113D) corresponding to the outer protrusions (115D). In this way, when channels (111D, 111E) and plugs (114D, 114E) with circular or elliptical cross-sections are applied, the outer surface of the plugs (114D, 114E) has no edges, so friction is reduced when inserted into the channels (111D, 111E) and insertion becomes smoother. In addition, since the circular or elliptical cross-sections have no stress concentration points, resistance to wear or fatigue failure caused by repeated insertion and removal is improved.

[0111] FIG. 10(e) shows an embodiment in which the channel (111E) and the plug (114E) have an elliptical cross-section. The plug (114E) may include a plurality of outer protrusions (115E) on its outer surface. The channel (111E) may include a plurality of inner grooves (113E) corresponding to the outer protrusions (115E).

[0112] FIG. 11 shows plugs (114F, 114G, 114H) and outer projections (115F, 115G, 115H) according to embodiments of the present disclosure.

[0113] FIG. 11(a) shows a plug (114F) viewed from a first direction (or front), illustrating an embodiment in which one outer projection (115F) is formed on each of the upper and lower surfaces and both sides of the plug (114F). Thus, the plug (114F) can be more firmly coupled to the channel (111) in the width direction of the port (10).

[0114] FIG. 11(b) shows a plug (114G) viewed from a first direction (or front), illustrating an embodiment in which two outer protrusions (115G) are formed on the upper and lower surfaces and on both sides of the plug (114G). Multiple outer protrusions (115G) may be arranged in a second direction (e.g., the X-axis direction in FIG. 11(b)) or a third direction (e.g., the Z-axis direction in FIG. 11(b)) for each surface of the plug (114G). Thus, the coupling force between the plug (114G) and the channel (111) can be further increased. Although the drawing shows two outer protrusions (115G) on each surface of the plug (114G), three or more outer protrusions (115G) may be formed on each surface.

[0115] FIG. 11(c) shows a plug (114H) viewed from a third direction (or top surface), illustrating an embodiment in which a plurality of outer protrusions (115H) are formed on the top surface and both sides of the plug (114H). Although obscured in the drawing, a plurality of outer protrusions (115H) may also be formed on the bottom surface of the plug (114H). A plurality of outer protrusions (115H) may be arranged in a first direction (e.g., the Y-axis direction in FIG. 11(c)) for each surface of the plug (114H). Thus, the bonding strength between the plug (114H) and the channel (111) can be further increased. The plurality of outer protrusions (115H) arranged on each surface of the plug (114H) may be arranged in a zigzag pattern so as to be staggered from each other. The drawing shows that five outer protrusions (115H) are formed on the upper surface of the plug (114H) and two outer protrusions (115H) are formed on both sides, but the number may vary.

[0116] FIG. 12 shows an outer projection (115I) and an inner groove (113I), a connecting projection (115J) and an inner groove (113J), a slit (115K) and a connecting rib (113K) according to embodiments of the present disclosure.

[0117] As shown in FIG. 12(a), the outer projection (115I) may traverse the outer surface of the plug (114I). For example, the outer projection (115I) may be on the outer surface of the plug (114I) and may have a straight shape extending in one direction. For example, the outer projection (115I) may extend in a second direction from the upper and lower surfaces of the plug (114I), respectively. The inner groove (113I) may be formed on the upper and lower surfaces of the channel (111I), respectively, to correspond to the outer projection (115I). For example, the outer projection (115I) may extend across the entire width direction (or second direction) of the plug (114I). The outer projection (115I) and the inner groove (113I), formed integrally without segmentation, may provide greater bonding force. Although the drawing shows that an outer projection (115I) is formed on the upper and lower surfaces of the plug (114I), an outer projection (115I) may also be formed on both sides of the plug (114I), and the same applies to the inner groove (113I). Additionally, two or more outer projections (115I) may be formed. For example, one or more outer projections (115I) may be formed on at least one of the upper surface, lower surface, and both sides of the plug (114I). Multiple plugs (114I) formed on each surface may be spaced apart from each other.

[0118] Alternatively, the outer projection (115I) may extend in two different directions. For example, the outer projection (115I) may extend in a first direction and a second direction on the surface of the plug (114I). Alternatively, the outer projection (115I) may extend at an angle with respect to the first direction and the second direction on the surface of the plug (114I). For example, the outer projection (115I) may have a shape such as a cross, an X, or an L. Thus, the outer projection (115I) and the inner groove (113I) can be more firmly joined in several different directions.

[0119] Alternatively, the plug (114I) may have a cylindrical shape, and the outer projection (115I) may have a ring shape extending along the outer surface of the plug (114I).

[0120] As shown in FIG. 12(b), the plug (114J) may include a plurality of segments (1141J). The plurality of segments (1141J) may each extend from the main body and be spaced apart from each other. Each segment (1141J) may include a coupling projection (115J). The coupling projection (115J) is formed on the outer surface (or end) of the segment (1141J) and may extend outward. For example, when the plug (114J) is inserted into the channel (111J), the coupling projection (115J) may protrude outward in a second direction toward the inner surface of the channel (111J). Each coupling projection (115J) may be inserted into an inner groove (113J). Although two segments (1141J) are shown in the drawing, there may be three or more segments (1141J). Additionally, the connecting projection (115J) may be formed on the upper and / or lower surface in addition to the outer surface of each segment (1141J).

[0121] Each segment (1141J) can be elastically deformed independently by being spaced apart from one another. When the plug (114J) is inserted into the channel (111J), each segment (1141J) can be elastically deformed toward the spaced-apart side by being pressed from the inner surface of the channel (111J). When the coupling projection (115J) reaches the inner groove (113J), the coupling projection (115J) can be returned outward by the elastic restoring force of the segment (1141J) and inserted into the inner groove (113J). The elasticity of the segment (1141J) can be controlled by one or more of the elastic modulus of the material constituting the segment (1141J), the thickness and length of the segment (1141J), and the distance between the segments (1141J). For example, as the thickness of the segment (1141J) decreases or the length increases, the amount of elastic deformation of the segment (1141J) increases, making insertion easier, and as the thickness of the segment (1141J) increases or the length decreases, the elastic restoring force increases, and the bonding strength can be improved. In addition, since multiple segments (1141J) undergo elastic deformation independently, each segment (1141J) can individually absorb minute dimensional deviations or manufacturing tolerances of the inner wall of the channel (111J), thereby improving the bonding reliability between the plug (114J) and the channel (111J).

[0122] In this way, when the plug (114J) includes a plurality of segments (1141J) spaced apart from each other, each segment (1141J) can absorb minute dimensional deviations or manufacturing tolerances of the inner wall of the channel (111J) by being elastically deformed independently. Therefore, the connection between the plug (114J) and the channel (111J) becomes more secure, and connection defects caused by manufacturing tolerances can be reduced.

[0123] In another embodiment, the number of segments (1141J) may be two, three, four, or more. As the number of segments (1141J) increases, the width of each segment (1141J) becomes narrower, making individual elastic deformation easier, and the contact points with the inner wall of the channel (111J) increase, allowing for a uniform distribution of bonding force. Additionally, multiple segments (1141J) may have the same size and shape, or different sizes and / or shapes. For example, the segment (1141J) located in the center of the width direction (second direction) may have a wider width than the segments (1141J) located on both sides, thereby increasing the support force in the center while facilitating elastic deformation on both sides.

[0124] As shown in FIG. 12(c), slits (115K) may be formed on the outer surface (or end) of the plug (114K). The slits (115K) may include a plurality of slits (115K) and may be spaced apart in the width direction (or the X-axis direction or second direction in FIG. 12(c)) of the plug (114K). The plurality of slits (115K) may be formed across the entire height direction of the plug (114K) or by cutting a portion of the upper and lower surfaces of the plug (114K). A plurality of connecting ribs (113K) corresponding to the plurality of slits (115K) may be formed in the channel (111K). The plurality of connecting ribs (113K) may be inserted between the plurality of slits (115K). Multiple connecting ribs (113K) guide the insertion of the plug (114K) into the channel (111K) and can increase the connecting force between the plug (114K) and the channel (111K). Slits (115K) may also be formed on both sides of the plug (114K), and connecting ribs (113K) may be formed on the inner side of the channel (111K) to correspond thereto.

[0125] In this way, when the connecting rib (113K) of the channel (111K) is inserted into the slit (115K) of the plug (114K), the connecting rib (113K) is guided along the slit (115K), thereby naturally determining the insertion direction of the plug (114K). Thus, the plug (114K) is prevented from being inserted into the channel (111K) at an angle, thereby preventing poor connection or damage to the port (10).

Those skilled in the art will fully understand that various modifications and equivalent alternative embodiments are possible from the embodiments. Accordingly, the true technical scope of protection of the present invention should be determined based on the appended claims.
