Description

Technical Field

[0001] The present invention relates to a discharge container equipped with a pump, and more particularly to a tubeless discharge container capable of stably discharging contents without using a plastic tube. Background Art

[0002] In cosmetic containers, for example, a pump is attached to the upper inlet of a container storing liquid or gel contents, such as perfume, to discharge and spray a fixed amount of the contents. When the user presses down on a nozzle corresponding to a button to spray the liquid contents, the contents flowing into the pump are pressurized, rising along a discharge channel and being discharged through the nozzle. When the user releases pressure on the nozzle, the discharge channel is mechanically closed by the nozzle's upward movement, and as the pressure inside the pump drops, the contents flow out of the container to be replenished.

[0003] Such pumps are used to discharge a variety of contents, such as perfumes and cosmetics, as well as fragrances, insecticides, etc. In particular, since the contents can be discharged quantitatively through a single nozzle under pressure and the contents are not exposed to the outside, they are convenient to use, and thus demand for them is increasing.

[0004] On the other hand, the pump is connected to a long plastic tube to discharge the contents from the container body that stores the contents, and the lower end of the tube is connected to the bottom surface of the container body. The suction force of the pump is transmitted to the inside of the tube, so that the contents stored in the container body flow into the pump through the tube. Although such a tube allows the entire contents stored in the container body to be used, it is inserted into the interior of the container body and is visible from the outside, thus becoming a factor that reduces the aesthetic appeal of the container. In particular, when the container corresponds to a cosmetic container, this problem of reduced aesthetic appeal is more prominent. Therefore, for containers using pumps, in order to prevent the tube from being exposed to the outside, the container body is often made of an opaque material. Summary of the Invention

[0005] Technical issues

[0006] Therefore, the present invention has been conceived to solve the above-mentioned problems, and an object of the present invention is to provide a tubeless discharge container that can stably discharge contents without using a plastic tube.

[0007] Other objects of the present invention will become more apparent from the embodiments described below.

[0008] Technical Solution

[0009] A tubeless discharge container according to one aspect of the present invention is used to discharge contents contained in a filling space, and may include: a bottle portion, which has the filling space formed therein and has a supply hole for the flow of the contents and an air hole for the inflow of air formed thereon; a connector portion, which is coupled to the upper portion of the bottle portion to spatially separate the supply hole and the air hole; and a pump portion, which is fixed to a specified position of the connector portion, is configured to inhale and discharge the contents supplied through the supply hole, and may have a supply flow path connecting the lower portion of the filling space and the supply hole formed on the bottle portion.

[0010] The tubeless discharge container of the present invention may include one or more of the following embodiments. For example, the bottle portion may include: an inner bottle having the filling space formed therein, an open bottom, and an upper flow path formed at its top, communicating with the supply hole; and an outer bottle having an inner diameter greater than the outer diameter of the inner bottle to accommodate the inner bottle therein, and a closed bottom. One end of the upper flow path may be open to the outer circumference of the inner bottle, and the other end of the upper flow path may be connected to the supply hole. The supply flow path may include the space between the inner and outer circumferences of the outer and inner bottles, and the upper flow path. The inner bottle may include: a flange formed at the top of the inner bottle; and an expanded diameter portion formed at a predetermined height below the flange, having an outer diameter corresponding to the inner diameter of the outer bottle, configured to closely contact the inner circumference of the outer bottle. The expanded diameter portion may include a downwardly open inflow groove, and one end of the upper flow path may be formed within the inflow groove.

[0011] The bottle portion may include an air inlet protrusion that protrudes upward from the upper surface of the bottle portion by a predetermined length and defines a passage on its inner side that communicates with the air hole. The connector portion may include an insertion groove that allows the air inlet protrusion to be pressed into contact with the outer peripheral surface of the air inlet protrusion. In this case, when the connector portion is coupled to the upper portion of the bottle portion, at least a portion of the bottom surface of the connector portion may be spaced apart from the upper surface of the bottle portion, so that the contents flowing out through the supply hole are supplied to the pump portion through the space between the connector portion and the bottle portion.

[0012] A recessed portion including a filling opening opened to the filling space may be formed on the upper surface of the bottle portion, and the connector portion may close the filling opening by partially inserting the connector portion into the recessed portion.

[0013] The bottle portion may include an annular mounting edge protruding upwardly by a predetermined length from the upper surface of the bottle portion, and the connector portion may be configured such that a portion thereof is pressed into the inner side of the mounting edge and abuts against the inner circumference of the mounting edge. In some embodiments, the connector portion may include an inner cover and a pump cover, the inner cover being pressed into the inner side of the mounting edge and abutting against the inner circumference of the mounting edge, and the pump cover being mounted on the outer side of the mounting edge and abutting against the outer circumference of the mounting edge.

[0014] Effects of the Invention

[0015] According to the technical solution of the present invention described above, various effects including the following can be expected. It should be noted that the present invention is not only effective when all of the following effects are exerted.

[0016] According to one embodiment of the present invention, a tubeless discharge container is provided, wherein the structure of the discharge container itself provides a supply path for the contents while effectively separating the supply path for the contents and the inflow path for air, thereby enabling stable discharge of the contents without the need for a plastic tube connected to a pump unit.

DETAILED DESCRIPTION

[0028] The present invention may be subjected to various modifications and may have a variety of embodiments. Specific embodiments will be illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the present invention to specific embodiments, and should be understood to include all variations, equivalents, and even substitutes that fall within the spirit and technical scope of the present invention. When describing the present invention, if it is determined that the detailed description of the relevant known technology may obscure the main purpose of the present invention, its detailed description will be omitted.

[0029] The terms used in this application are intended only to describe specific embodiments and are not intended to limit the present invention. Unless otherwise clearly defined in the context, expressions in the singular include expressions in the plural. In this application, terms such as "including" or "having" should be understood to be intended to specify the presence of features, numbers, steps, actions, constituent elements, parts, or combinations thereof recorded in the specification, and do not preclude the presence or addition of one or more other features or numbers, steps, actions, constituent elements, parts, or combinations thereof.

[0030] The terms "first" and "second" can be used to describe various components, but these components should not be limited by these terms. These terms are only used to distinguish one component from another.

[0031] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. When describing with reference to the accompanying drawings, the same or corresponding components are given the same reference numerals regardless of the reference numerals, and repeated description thereof is omitted.

[0032] Figure 1 1 is a perspective view showing a state where the top cover 10 is separated from the tubeless discharge container 1000 according to one embodiment of the present invention. Figure 2 It shows that Figure 1The cross-sectional view of the tubeless discharge container 1000 is taken along the AA' direction. Figure 3 yes Figure 1 An exploded perspective view of a tubeless drain container 1000 is shown.

[0033] Reference Figures 1 to 3 The tubeless discharge container 1000 of one embodiment of the present invention may be a container for discharging contents (not shown) contained in a filling space 905 , and may generally include a bottle portion 950 , a connector portion 750 , and a pump portion 450 .

[0034] The bottle portion 950 may have a filling space 905 formed therein, and may have a supply hole 980 for the flow of the contents and an air hole 965 for the inflow of air formed thereon. A supply flow path connecting the lower portion of the filling space 905 and the supply hole 980 may also be formed in the bottle portion 950. That is, one end of the supply flow path of the bottle portion 950 may be connected to the lower portion of the filling space 905, and the supply hole 980 may be provided at the other end. Therefore, when the filling space 905 is filled with contents (not shown), the air hole 965 may be located above the surface of the contents (not shown), and one end of the supply flow path may be located below the surface of the contents (not shown), with reference to the surface of the liquid or gel-like contents (not shown).

[0035] The connector portion 750 may be coupled to the upper portion of the bottle portion 950 and may function to spatially separate the supply hole 980 and the air hole 965 of the bottle portion 950 while providing a space for installing the pump portion 450 and specifying a position of the pump portion 450 .

[0036] The pump unit 450 can be fixed to a designated position on the connector unit 750 to draw in and discharge the contents (not shown) supplied through the supply hole 980. Specifically, when the user applies pressure to the nozzle 100 with the top cover 10 removed, the pump guide 500 descends to open the pump inlet hole 540, allowing the contents of the pump space 650 to enter and be discharged through the discharge port 130 via the guide passage 550, the valve space 250, the nozzle space 150, and the nozzle passage 140.

[0037] Thus, in one embodiment of the tubeless discharge container 1000 of the present invention, the bottle portion 950 itself can provide the supply flow path, replacing the conventional plastic tube. Thus, even if the bottle portion 950 is made of a transparent material, the problem of the bulky plastic tube inside being visible and thus detracting from the aesthetic appeal of the discharge container 1000 can be solved.

[0038] On the other hand, in order to maintain the air pressure inside filling space 905 at a predetermined level by sucking the contents from the discharge container using the pump, the pump side requires a pressure lower than the air pressure inside filling space 905. When a plastic tube is directly connected to the pump, as in the prior art, this negative pressure is easily generated simply by improving the airtightness of the pump itself. However, when the supply flow path is formed by combining multiple parts, as in one embodiment of the present invention, it is very important to airtightly separate the portion where negative pressure should be generated from the portion where normal pressure should be maintained.

[0039] If you refer to Figure 3 An embodiment of the present invention will be described in more detail. In an embodiment of the present invention, a tubeless discharge container 1000 may include, in addition to a top cover 10 detachably coupled to the upper portion, a pump portion 450, a connector portion 750, and a bottle portion 950. The pump portion 450 may include a nozzle 100, a valve 200, an elastomer 260, an outer shell cover 300, a piston 400, a guide 500, a disc 530, and an outer shell 600. The connector portion 750 may include a pump cover 700 and an inner cover 800. The bottle portion 950 may include an inner bottle 900 and an outer bottle 990.

[0040] The nozzle 100 may correspond to the portion that is pressurized by the user and accordingly discharges the contents. The nozzle 100 may be configured with an open bottom and may have a discharge port 130 formed on one side. The nozzle 100 may have a space formed inside by the outer frame 110, and a connecting boss 120 may be formed inside the outer frame 110. The connecting boss 120 may have, for example, a cylindrical shape with an open bottom and may define a nozzle space 150 inside.

[0041] A nozzle channel 140 may be formed at the upper portion of the nozzle 100. One end of the nozzle channel 140 may communicate with the nozzle space 150, and the other end may be connected to the discharge port 130. The connection boss 120 of the nozzle 100 may be inserted into the connection portion 230 of the valve 200 and coupled and fixed to the valve 200. When the nozzle 100 and the valve 200 are raised and lowered together, the outer frame 110 of the nozzle 100 may move along the inner circumferential surface of the pump coupling portion 720 of the pump cover 700.

[0042] The valve 200 may be combined with the nozzle 100 and the guide 500, and may operate the piston 400 and the guide 500 by pressure from the user and the restoring force of the elastic body 260. The valve 200 may have a hollow cylindrical shape as a whole and may include a head 210, a connecting portion 230, and a cylinder portion 240.

[0043] The head portion 210 may protrude outward from the upper end of the valve 200 and then extend downward to form a connection groove 220. The upper portion 270 of the elastic body 260 may be inserted into and fixed to the connection groove 220.

[0044] As the connecting boss 120 of the nozzle 100 is inserted into the connecting portion 230, the nozzle 100 and the valve 200 can be coupled to each other. As shown in the figure, the connecting boss 120 and the connecting portion 230 are respectively formed with steps that abut each other. Therefore, when the nozzle 100 is pressurized downward, the valve 200 can be pressurized downward by the nozzle 100, and when the valve 200 moves upward, the nozzle 100 can be pressurized upward by the valve 200. By forming mutually engaging protrusions and grooves on the outer circumferential surface of the connecting boss 120 and the inner circumferential surface of the connecting portion 230, the connection between the connecting boss 120 and the connecting portion 230 can be made more secure. When the connecting boss 120 is inserted into the connecting portion 230, the valve space 250 of the valve 200 can be connected to the nozzle space 150 of the nozzle 100.

[0045] The cylinder portion 240 can be configured as a hollow cylindrical shape. The rod 520 of the guide member 500 can be inserted into the interior space of the cylinder portion 240, thereby allowing the interior space of the cylinder portion 240 to have an inner diameter corresponding to the outer diameter of the rod 520. It should be noted that the inner contact portion 430 of the piston 400 can also be inserted into the lower portion of the interior space of the cylinder portion 240 and can have a correspondingly larger inner diameter. By forming a coupling protrusion 245 on the inner circumference of the cylinder portion 240 and a corresponding groove on the outer circumference of the rod 520, the connection between the valve 200 and the guide member 500 can be further strengthened.

[0046] The elastomer 260 can be coupled between the valve 200 and the outer shell 300 or the outer shell 600, and serves to return the nozzle 100, the valve 200, and the guide member 500 to their original positions through elasticity when the external force generated by the user's pressure is released. The elastomer 260 of one embodiment of the present invention can be formed of an elastically deformable material and can have a hollow tubular shape as a whole. The upper portion 270 of the elastomer 260 can be coupled to the valve 200 by, for example, being inserted into the connecting groove 220 of the head 210, and the lower portion 290 of the elastomer 260 can be coupled to the outer shell 300 or the outer shell 600 by a similar method. For example, the figure shows an example in which a portion of the outer shell 300 is inserted into the inner side of the lower portion 290 of the elastomer 260 for coupling.

[0047] A reinforcing rib 280 may be formed in the middle of the elastic body 260. The reinforcing rib 280 is a portion formed with a greater thickness to limit elastic deformation, which prevents folding, warping, etc. from occurring in a portion of the elastic body 260, thereby enabling the elastic body 260 to provide a restoring force more effectively.

[0048] The outer shell 300 can be coupled to the upper portion of the outer shell 600 to enhance the airtightness between the valve 200 and the outer shell 600. The outer shell 300 can include an upper head 310 and a contact portion 330 extending vertically for a predetermined length. The head 310 of the outer shell 300 can protrude outward from the upper end of the outer shell 300 and then extend downward to form a connection groove 320. The upper portion of the outer shell 600 can be inserted into and secured to the connection groove 320 of the outer shell 300. The cylinder 240 of the valve 200 can be configured to rise and fall within the outer shell 600 and can be inserted through a central hole in the contact portion 330. The contact between the valve 200 and the outer shell 300 is achieved through surface contact along the upper and lower lengths of the contact portion 330, thereby providing a high degree of airtightness, enabling the pump space 650 within the outer shell 600 to maintain a pressure environment isolated from the outside.

[0049] The piston 400 can be mounted on the rod 520 of the guide member 500 and can include an outer contact portion 410, a bridge 420, and an inner contact portion 430. The outer contact portion 410 can be configured to be in close contact with the inner circumferential surface of the housing 600, and the inner contact portion 430 can be configured to contact the rod 520 of the guide member 500. The bridge 420 can connect the outer contact portion 410 and the inner contact portion 430. When the nozzle 100 is not pressurized, the piston 400 can be positioned to close the pump inlet hole 540 formed in the guide member 500.

[0050] The guide member 500 can be coupled to the valve 200 and configured to rise and fall within the housing 600 in response to pressure applied by the user. The guide member 500 can include a head 510 and a rod 520. The head 510 can be located within the pump space 650 of the housing 600 and have a larger diameter than the piston 400, thereby forming a step below the piston 400. The rod 520 can be extended and have a hollow cylindrical shape with a guide member channel 550 formed therein. One or more pump inlet holes 540 formed in the rod 520 can connect the guide member channel 550 to the exterior of the guide member 500.

[0051] The disc 530 may be disposed at the lower portion of the housing 600 and include a plurality of holes so that the housing inflow hole 630 at the lower portion of the housing 600 is not blocked even when the guide member 500 is fully lowered.

[0052] The housing 600 may form a pump space 650 that draws in contents and allows the piston 400 and guide member 500 to rise and fall. The housing 600 may include a flange 610 and a body 620. The body 620 of the housing 600 may be inserted into the accommodation space 850 of the inner cover 800, and the pump space 650 may be formed within the body 620. One or more housing inlet holes 630 may be formed at designated locations on the lower portion of the body 620. The flange 610 may protrude outward from the upper portion of the housing 600 and facilitate the connection of the housing 600 to the connector 750.

[0053] When a user applies pressure to the nozzle 100, the nozzle 100, along with the valve 200 and guide 500 attached thereto, descends together. However, the piston 400, due to friction generated by its close contact with the housing 600, does not immediately descend. Since the piston 400 does not descend while the guide 500 descends, the pump inlet 540 of the guide 500 can be opened. After the guide 500 descends a predetermined distance, the lower end of the valve 200 applies pressure to the bridge 420 of the piston 400, causing the piston 400 to descend as well. However, the pump inlet 540 of the guide 500 can remain open. As the guide 500 descends, the volume of the pump space 650 decreases. Due to the increased pressure, the contents (not shown) that had previously flowed into the pump space 650 can be drawn into the open pump inlet 540. The contents that entered the pump inlet 540 can then be discharged through the guide passage 550, the valve space 250, the nozzle space 150, and the nozzle passage 140 through the discharge port 130.

[0054] When the user stops applying pressure to the nozzle 100, the restoring force of the elastomer 260 causes the nozzle 100, the valve 200 attached thereto, and the guide 500 to rise together. Similarly, the piston 400 is prevented from rising immediately due to friction generated by its close contact with the housing 600. The piston 400 does not rise, while the guide 500 does, thereby sealing the pump inlet 540 of the guide 500. After the guide 500 rises a predetermined distance, the head 510 of the guide 500 applies pressure to the piston 400, causing the piston 400 to rise together. However, at this time, the pump inlet 540 of the guide 500 remains sealed. As the guide 500 rises, the volume of the pump space 650 increases, and due to the reduced pressure, the contents of the fill space 905 (not shown) can flow into the pump space 650 through the supply flow path.

[0055] As long as the above-mentioned effects can be produced, some of the above-mentioned components of the pump unit 450 may be integrated into one component.

[0056] The bottle portion 950 of the tubeless discharge container 1000 according to one embodiment of the present invention will be described in more detail below.

[0057] Figure 4 1 is a perspective view showing an inner bottle 900 of a tubeless discharge container 1000 according to an embodiment of the present invention. Figure 5 yes Figure 4 A top view and a bottom view of the inner bottle 900 are provided.

[0058] Reference Figures 2 to 5 The bottle portion 950 may include an inner bottle 900 and an outer bottle 990. The inner bottle 900 may have a hollow cylindrical shape as a whole, wherein a filling space 905 may be formed inside and the lower side may be open. A channel portion 947 may be provided at the upper portion of the inner bottle 900 to form an upper flow path 945. One end of the upper flow path 945 may be open to the outer circumference of the inner bottle 900, and the other end may be connected to the supply hole 980.

[0059] The outer bottle 990 can also have a hollow cylindrical shape as a whole, the lower side of the outer bottle 990 can be closed, and when the inner bottle 900 is inserted into the interior of the outer bottle 990, the space 995 between the inner circumferential surface of the outer bottle 990 and the outer circumferential surface of the inner bottle 900 can form a part of the supply flow path.

[0060] That is, Figure 2 As shown, when the inner bottle 900 is combined with the outer bottle 990, a predetermined distance can be formed between the outer circumferential surface of the inner bottle 900 and the inner circumferential surface of the outer bottle 990, and a predetermined distance can also be formed between the open lower portion of the inner bottle 900 and the lower surface of the outer bottle 990. When it is necessary to flow the contents of the filling space 905 into the pump space 650, the contents of the filling space 905 can flow from the open lower portion of the inner bottle 900 into the space 995 between the outer bottle 990 and the inner bottle 900, and then, due to negative pressure, rise along the outer circumferential surface of the inner bottle 900 and flow into the upper flow path 945, flow into the recessed portion 970 through the supply hole 980, and flow into the pump space 650 through the housing inflow hole 630.

[0061] Reference Figure 4 and Figure 5 The inner bottle 900 may generally include a flange 910 , a body 920 , a mounting edge 930 , and an air intake protrusion 960 .

[0062] The flange 910 may be formed by protruding outward from the upper portion of the inner bottle 900 and may provide a step for the pump cover 700 to be placed when the top cover 10 is combined. In one embodiment of the present invention, the flange 910 may also be used to combine the inner bottle 900 and the outer bottle 990.

[0063] The body 920 can extend while maintaining a predetermined outer diameter over most of its vertical length. The lower side of the body 920 can be open, and a filling space 905 can be formed inside. In a preferred embodiment, the body 920 is entirely formed of a transparent or translucent material.

[0064] The mounting flange 930 may have an annular shape and protrude a predetermined length from the upper surface of the inner bottle 900. The mounting flange 930 may be in close contact with the connector portion 750 to seal the supply flow path and connect the connector portion 750 to the bottle portion 950. A protrusion 935 for connecting and sealing the connector portion 750 may be provided on the outer circumference of the mounting flange 930.

[0065] The air inlet protrusion 960 may protrude upward from the upper surface of the inner bottle 900 by a predetermined length. The air inlet protrusion 960 may be formed in a hollow cylindrical shape, and the inner channel may be connected to the air hole 965. That is, the inner channel of the air inlet protrusion 960 may be regarded as an extension of the air hole 965.

[0066] A recessed portion 970 may be formed on the inner bottle 900. The recessed portion 970 may be formed to correspond to the position of the pump portion 450 and to accommodate a portion of the pump portion 450 and the connector portion 750. Of course, in some embodiments, the recessed portion 970 may be omitted or implemented as other structures.

[0067] In one embodiment of the present invention, a filling opening 975 may be formed below the recessed portion 970. The filling opening 975 is an opening communicating with the filling space 905 and may serve as an inlet for filling the tubeless discharge container 1000 with contents. The filling opening 975 may be configured to be subsequently closed when a portion of the connector portion 750 or a portion of the pump portion 450 is inserted into the recessed portion 970. To this end, a locking protrusion 977 may be formed on the inner circumferential surface of the filling opening 975. In some embodiments (not shown), the filling opening 975 may also be formed at another location, such as below the outer bottle 990.

[0068] One or more supply holes 980 may be formed on the upper surface of the inner bottle 900. As previously described, the supply holes 980 may correspond to the ends of the upper flow path 945. A hollow channel portion 947 may be formed on the inner lower surface of the upper surface of the inner bottle 900 to form the upper flow path 945 within the channel portion 947. One end of the upper flow path 945 may be open to the outer circumference of the inner bottle 900, while the other end may be connected to the supply hole 980.

[0069] The body 920 of the inner bottle 900 can maintain a predetermined outer diameter as a whole and the outer diameter is smaller than the inner diameter of the outer bottle 990, so as to form a narrow space 995 between the inner bottle 900 and the outer bottle 990. Figure 4As shown, an expanded diameter portion 940 having an outer diameter greater than that of the body 920 may be formed below the flange 910 on the upper portion of the body 920 of the inner bottle 900 .

[0070] The expanded diameter portion 940 may be configured to have an outer diameter corresponding to the inner diameter of the outer bottle 990 so as to be in close contact with the inner circumferential surface of the outer bottle 990. An inflow groove 942 may be formed in the expanded diameter portion 940 at a position corresponding to the end of the upper flow path 945, and the end of the upper flow path 945 may be formed inside the inflow groove 942.

[0071] When the inner bottle 900 and the outer bottle 990 are combined, the main body 920 of the inner bottle 900 can be inserted into the inner portion of the outer bottle 990. In one embodiment of the present invention, the bottle portion 950 itself is required to provide a supply flow path, rather than a plastic tube being inserted into the filling space 905. Therefore, a predetermined distance needs to be formed between the open lower portion of the inner bottle 900 and the lower surface of the outer bottle 990, and a space 995 of a predetermined width needs to be formed between the outer circumference of the inner bottle 900 and the inner circumference of the outer bottle 990.

[0072] When the main body 920 of the inner bottle 900 is inserted through the upper part of the opening of the outer bottle 990, the flange 910 of the inner bottle 900 is stopped at the upper part of the outer bottle 990, thereby preventing further entry. At this time, the required distance can be formed between the lower part of the main body 920 of the inner bottle 900 and the bottom of the outer bottle 990.

[0073] On the other hand, because the expanded portion 940 located below the flange 910 has an outer diameter corresponding to the inner diameter of the outer bottle 990 and is securely attached to the inner circumference of the outer bottle 990, when the expanded portion 940 is inserted into the outer bottle 990, the body 920 of the inner bottle 900 is aligned in the designed position, thereby creating a desired distance between the outer circumference of the inner bottle 900 and the inner circumference of the outer bottle 990. Furthermore, since the expanded portion 940 is securely attached to the inner circumference of the outer bottle 990, the contents cannot pass through the expanded portion 940. However, one end of the upper flow path 945 is formed within the inflow groove 942, so that one end of the upper flow path 945 is not blocked, and the inflow groove 942 is open downward, thereby allowing communication with the space 995 between the inner bottle 900 and the outer bottle 990.

[0074] While the lower portion of the inner bottle 900 is depicted as having a uniform cylindrical height, portions of the lower portion of the inner bottle 900 may have varying heights and thus partially contact the lower surface of the outer bottle 990. Furthermore, similar to the expanded diameter portion 940, a portion having an outer diameter corresponding to the inner diameter of the outer bottle 990 may be formed in the lower portion of the inner bottle 900. Of course, in this case, grooves or holes may be formed where necessary to prevent obstruction of the supply path for the contents. As described above, in the embodiment where the inner bottle 900 and the outer bottle 990 are in contact with each other, ultrasonic welding or other methods may be applied to the contacting portions of the lower portion of the inner bottle 900. It should be noted that when the lower part of the inner bottle 900 is welded to the bottom of the outer bottle 990, there is a concern that the possibility of the distance between the inner bottle 900 and the outer bottle 990 being different from the design value will increase. When the lower part of the inner bottle 900 is provided with an expanded diameter part, the inner bottle 900 may be difficult to insert into the outer bottle 990. Therefore, as in the illustrated embodiment, it may be beneficial to realize the combination of the inner bottle 900 and the outer bottle 990 at the upper part.

[0075] When the contents are filled into the filling space 905, based on the surface of the liquid or gel-like contents (not shown), the air holes 965 can be located above the surface of the contents (not shown), that is, on the upper side of the inner bottle 900, and one end of the supply flow path can be located below the surface of the contents (not shown), that is, at the lower part of the inner bottle 900. Therefore, the movement path of the contents and the movement path of the air are spatially separated by the contents themselves before the contents (not shown) are exhausted, and thus have different pressure conditions.

[0076] The ductless discharge container 1000 of one embodiment of the present invention utilizes its own structure to provide a supply flow path, rather than using a plastic tube. Therefore, the overall structure of the ductless discharge container 1000 must maintain a high degree of airtightness between the paths for the contents and the paths for air. The structure of the connector 750 that enables the ductless discharge container 1000 of one embodiment of the present invention to maintain a high degree of airtightness will be described in more detail below.

[0077] Figure 6 1 is a perspective view showing an inner cover 800 of a tubeless discharge container 1000 according to an embodiment of the present invention. Figure 7 1 is a perspective view showing a pump cover 700 of a tubeless discharge container 1000 according to an embodiment of the present invention.

[0078] Reference Figure 6The inner cover 800 of the tubeless discharge container 1000 of the present invention can generally include a flat plate portion 830 in the shape of a circular flat plate, a close edge 820 extending upward from the edge of the flat plate portion 830, a flange 810 extending outward from the upper part of the close edge 820, an insertion portion 840 and a protruding portion 860 protruding upward from the flat plate portion 830, and accommodating portions 870 and 880 protruding upward and downward from the middle of the flat plate portion 830.

[0079] The flat plate portion 830 may be implemented in the shape of a circular flat plate and may be implemented in a size corresponding to the area inside the mounting edge 930 of the inner bottle 900. A contact edge 820 may extend upward from the edge of the flat plate portion 830, and a flange 810 may be formed at an end of the contact edge 820 and extend outward.

[0080] The outer diameter of the abutment edge 820 can be sized to correspond to the inner diameter of the mounting edge 930 of the inner bottle 900. Thus, the inner cap 800 can be pressed into the inner side of the mounting edge 930 and attached to the upper portion of the inner bottle 900. After attachment, the outer circumference of the abutment edge 820 can be in close contact with the inner circumference of the mounting edge 930. To provide even higher airtightness, one or more sealing protrusions 825 can be formed on the outer circumference of the abutment edge 820. The extension length of the abutment edge 820 can be slightly shorter than that of the mounting edge 930. As a result, when the inner cap 800 is attached to the inner bottle 900, the flange 810 of the inner cap 800 is locked onto the upper portion of the mounting edge 930, and the flat portion 830 does not come into close contact with the upper surface of the inner bottle 900. The resulting gap between the flat portion 830 and the upper surface of the inner bottle 900 forms a portion of the supply flow path between the upper flow path 945 and the accommodating space 850 (described later).

[0081] Insertion portion 840 protrudes upward from flat plate portion 830 and has a hollow cylindrical shape, thereby forming an insertion groove 845 open to the bottom. A protrusion 860 having a hollow cylindrical shape can be formed on the upper portion of insertion portion 840, and a channel 865 of protrusion 860 can communicate with insertion groove 845. It should be noted that the inner diameter of insertion groove 845 can be formed to be larger than the inner diameter of channel 865 of protrusion 860.

[0082] When the inner cap 800 is mounted on the inner bottle 900, the air inlet protrusion 960 of the inner bottle 900 can be pressed into the insertion groove 845, and the outer circumference of the air inlet protrusion 960 can be closely attached to the inner circumference of the insertion portion 840. In this state, the channel of the air inlet protrusion 960 (i.e., the air hole 965) can be connected to the channel 865 of the protrusion 860. Therefore, the protrusion 860 can also be considered to extend the air inlet protrusion 960. The inner diameter of the insertion portion 840 can correspond to the outer diameter of the air inlet protrusion 960, and the inner diameter of the protrusion 860 can correspond to the inner diameter of the air inlet protrusion 960.

[0083] In structures requiring airtightness, one of the most vulnerable locations for unwanted air infiltration is the interface between components. In the ductless discharge container 1000 according to one embodiment of the present invention, air must be allowed to flow through the air holes 965 communicating with the filling space 905, while air must be completely blocked in the remaining areas. Therefore, sealing around the air inlet protrusion 960 of the inner bottle 900 is particularly important. By extending the air inlet protrusion 960 to a predetermined length and pressing it into the insertion groove 845 to a predetermined depth, the interface between the inner cap 800 and the inner bottle 900 formed around the air inlet protrusion 960 is extended. Because the infiltration path through the interface between the inner cap 800 and the inner bottle 900 is blocked by surface contact over a longer distance, unwanted air infiltration can be effectively prevented.

[0084] The accommodating portions 870 and 880 protrude upward and downward from the flat plate portion 830 and are hollow, thereby forming an accommodating space 850 therein. The accommodating portion 870 formed at the upper portion of the flat plate portion 830 may be open to the upper side, and the accommodating portion 880 formed at the lower portion of the flat plate portion 830 may be implemented with its lower side closed. The pump portion 450 may be inserted into and installed in the accommodating space 850. In order to secure the pump portion 450 and seal the area surrounding the pump portion 450, one or more sealing protrusions 855 may be provided within the accommodating space 850.

[0085] One or more container inflow holes 885 may be formed in the container 880 formed at the lower portion of the flat plate portion 830. The container inflow holes 885 may connect the outside and inside of the container 880, and may connect the inside of the recessed portion 970 and the inside of the container 880. As a result, the contents guided from the filling space 905 to the supply hole 980 via the upper flow path 945 may move into the inside of the recessed portion 970 adjacent to the supply hole 980, and move into the inside of the container space 850 through the container inflow holes 885 via the space between the inner circumferential surface of the recessed portion 970 and the outer circumferential surface of the container 880, and then move into the inside of the pump space 650 through the housing inflow hole 630 within the container space 850.

[0086] When a filling opening 975 is formed in the recessed portion 970 of the inner bottle 900, a plug 890 may be provided at the lower end of the accommodating portion 880 formed at the lower portion of the flat plate portion 830. The plug 890 can be inserted into the filling opening 975 to seal it. A protrusion 895 may be formed on the outer circumference of the plug 890. By engaging the protrusion 895 with a step formed around the filling opening 975 of the inner bottle 900, the inner cap 800 is secured while preventing air from penetrating through the filling opening 975. The plug 890 may also be provided with an O-ring or the like to enhance airtightness. If the filling opening 975 is formed at another location, such as the bottom of the outer bottle 990, the plug 890 may be omitted.

[0087] The lower surface of the flat plate portion 830 of the inner cover 800 forms a portion of the supply path for the contents (not shown). An insertion groove 845, which forms a path for air flow, is formed on the lower surface of the flat plate portion 830. However, since the air holes 965 connected to the filling space 905 are connected to the upper portion of the air inlet protrusion 960, they are not exposed to the lower surface of the flat plate portion 830. In other words, the boundary surface from the outlet of the air hole 965 to the lower surface of the flat plate portion 830 is blocked by surface contact over a length corresponding to the depth of the insertion groove 845, thereby spatially separating the flow paths of the contents and air, thereby achieving a high degree of airtightness.

[0088] Reference Figure 7 The pump cover 700 of the tubeless discharge container 1000 of the present invention may generally include an outer mounting portion 710 and an inner mounting portion 720 .

[0089] The outer mounting portion 710 may include an annular portion and an inwardly extending portion. The outer mounting portion 710 may be closely attached to the exterior of the mounting edge 930 of the inner bottle 900. The inner circumferential surface of the outer mounting portion 710 may be provided with one or more protrusions 717 for securing and sealing the inner bottle 900 to the mounting edge 930. The outer circumferential surface of the outer mounting portion 710 may also be provided with one or more locking protrusions 715 for attaching and detaching the top cover 10.

[0090] The inner mounting portion 720 may be formed to extend obliquely in a truncated cone shape, and may expose the nozzle 100 at an open upper portion. The inner mounting portion 720 may provide a space for accommodating the pump unit 450 and fix the outer housing 300 and the nozzle 100.

[0091] A step portion 740 that protrudes inward to provide a step may be formed on the inner side of the inner mounting portion 720, and a fixing portion 760 that extends downward from the inner side of the step portion 740 may be formed. The fixing portion 760 may have a hollow cylindrical shape and may have a through hole 755 formed therein. Figure 7As shown, an insertion portion 770 may be further formed at the lower portion of the step portion 740. The insertion portion 770 may have a hollow cylindrical shape to form an insertion groove 775 therein. On the other hand, a groove may be formed at a designated position of the step portion 740, and the air hole 725 may be formed in the groove.

[0092] When the pump cover 700 and the inner cover 800 are coupled together, the protrusion 860 of the inner cover 800 can be pressed into the insertion groove 775 of the pump cover 700, and the outer circumferential surface of the protrusion 860 can be closely attached to the inner circumferential surface of the insertion portion 770. In this state, the channel 865 of the protrusion 860 can communicate with the air hole 725 of the step portion 740. As a result, the air hole 965 formed in the upper portion of the filling space 905 can be connected to the outside through the air hole 965 of the air inlet protrusion 960 of the inner bottle 900, the channel 865 of the protrusion 860 of the inner cover 800, and the air hole 725 of the pump cover 700.

[0093] On the other hand, when the pump unit 450 is coupled to the pump cover 700, it can be inserted through the through-hole 755 of the inner mounting portion 720 and positioned within the recessed portion 970 of the inner bottle 900 and the accommodating space 850 of the inner cover 800. When the pump unit 450 is inserted with sufficient pressure, the head portion 310 of the outer housing 300 can be pressed under the fixing protrusion 730 of the stepped portion 740 and fixed between the stepped portion 740 and the fixing protrusion 730. Of course, in some embodiments, the structure can be modified so that the head portion 310 of the outer housing 300 is positioned between the pump cover 700 and the inner cover 800. It should be noted that the structure of the illustrated embodiment has the advantage of simplifying the assembly process, thereby saving time and cost.

[0094] Within the scope that can produce the above-mentioned effect, the components of the connecting part 750, namely the pump cover 700 and the inner cover 800, can be integrated into one component, but for the convenience of manufacturing and assembly, they can also be made and assembled separately.

[0095] Refer to the following Figure 8 and Figure 9 The flow paths of the contents and air in the interior of the ductless discharge container 1000 will be described. Figure 8 and Figure 9 They are shown as follows Figure 1 The cross-sectional view of a portion of the tubeless discharge container 1000 is shown along the AA′ direction and the BB′ direction.

[0096] First, refer to Figure 2 and Figure 8 , when the user is Figure 8When the nozzle 100 is pressurized in a negative pressure state and then the pressurization is stopped, thereby generating a negative pressure in the pump space 650, the contents (not shown) in the filling space 905 can flow from the lower part of the filling space 905 through the space 995 between the inner bottle 900 and the outer bottle 990 to the upper part of the inner bottle 900, and then move to the supply hole 980 through the upper flow path 945, enter the interior of the recessed portion 970, and be supplied to the pump space 650 through the housing inflow hole 630. Subsequently, when the nozzle 100 is pressurized again, the contents in the pump space 650 can be discharged through the pump portion 450 using the discharge port 130 of the nozzle 100.

[0097] Reference Figure 9 , the air inlet protrusion 960 of the inner bottle 900 is inserted into the insertion groove 845 of the inner cover 800, and the protrusion 860 of the inner cover 800 is inserted into the insertion groove 775 of the pump cover 700. Therefore, the air hole 965 formed on the upper surface of the inner bottle 900 can be connected to the air hole 725 of the inner mounting portion 720 of the pump cover 700 through the protrusion 860 of the inner cover 800 and the insertion portion 770 of the pump cover 700.

[0098] As noted above, the tubeless discharge container 1000 of one embodiment of the present invention can provide a flow path for the contents solely through its own structure, without the need for a plastic tube. Unlike conventional plastic tubes, maintaining high airtightness throughout the discharge container is crucial. In particular, the contact areas between different components are particularly vulnerable to air infiltration, requiring effective prevention of air infiltration.

[0099] The ductless discharge container 1000 of one embodiment of the present invention basically comprises a relatively small number of parts, some of which can be integrated and implemented with a smaller number of parts. Due to the small number of parts, the boundaries between the parts are reduced, which can greatly reduce the possibility of air infiltration. In addition, Figure 8 and Figure 9 As shown, in a tubeless discharge container 1000 according to one embodiment of the present invention, the interface between the inner bottle 900, inner cap 800, and pump cap 700 is blocked by surface contact over a predetermined length, thereby blocking portions where air infiltration is a concern. Specifically, when extended beyond a predetermined length, the mounting flange 930, protrusion 860, receiving portions 870 and 880, and air intake protrusion 960 are in close contact over the entire extended length.

[0100] This structure significantly improves the airtightness of the contact boundary portions between components, which may be particularly vulnerable to unwanted air infiltration, allowing the tubeless discharge container 1000, which does not use a plastic tube, to perform a smooth discharge function solely through its own structure. In the illustrated embodiment, the aforementioned structure is omitted only in portions such as around the filling opening 975 and at one end of the upper flow path 945, where airtightness can be easily achieved by heat welding or other methods such as using an O-ring.

[0101] Although the present invention has been described above with reference to an embodiment, it will be understood by those skilled in the art that the present invention may be variously modified and altered without departing from the spirit and scope of the invention as described in the claims.
