Description

Technical Field

[0001] The present invention relates to a container for discharging liquid contents, and more particularly to a container for discharging liquid contents having a discharge valve that opens and closes a discharge passage by means of the discharge pressure of the liquid contents and an air inlet valve that opens and closes an air inlet in response to the pressure inside the container to stably maintain the seal and pressure inside the container. Background Technology

[0002] Today, in line with the rapidly diversifying trends of modern society, people of all ages and genders use cosmetics according to their needs. In particular, women are using various types of cosmetics, makeup products in a variety of colors, and makeup tools. Furthermore, thanks to the research and development of cosmetic companies, a wide range of high-quality makeup products and tools are launched into the market every day.

[0003] The above-mentioned cosmetics can be classified according to their purpose as follows: facial cleansing cosmetics used to remove sebum, waste and pollutants from the skin surface; basic cosmetics used to properly supply moisture and oil to the skin; color cosmetics used to create a beautiful color impression; hair care cosmetics used to remove foreign objects from the hair or scalp while protecting and nourishing the hair; and perfumes that impart fragrance to others by dissolving fragrance in alcohol.

[0004] Meanwhile, with the improvement of living standards, people are paying more and more attention to the safety of cosmetic compositions and skin care. Therefore, many of the aforementioned cosmetics are made from natural ingredients. However, these cosmetics do not contain additives such as preservatives to minimize skin irritation. Therefore, compared to cosmetics made from chemical ingredients, their disadvantage is a relatively higher risk of spoilage. For example, when using these cosmetics, they may become contaminated or spoiled due to bacterial penetration from external air contact or oxidation caused by air exposure.

[0005] In addition, containers with simple opening and closing functions have been used to store and use beauty agents in liquid or gel form, such as lotions, creams, gels, shampoos, conditioners, etc. However, with these containers, users need to take the cosmetics out of the container with a spatula or their fingers and apply them to their skin or hair, which is very inconvenient.

[0006] Therefore, tubular cosmetic containers are used to expel cosmetics to the outside by squeezing the container and changing the internal pressure, or pump-type cosmetic containers are used to draw and expel cosmetics by the suction operation of a pump.

[0007] In the structure of a tubular cosmetic container, when the user changes the internal pressure of the container by squeezing the soft container inward, the cosmetics contained in the container are discharged to the outside through the nozzle outlet.

[0008] However, in the case of tubular cosmetic containers, there is a risk that the cosmetics contained in the container may still be contaminated due to exposure to the outside through the nozzle outlet. Furthermore, as the cosmetics are discharged and used, the shape of the container may shrink and deform, resulting in an unsightly appearance. In addition, it is difficult to store and use the container upright. And because the container is mainly composed of a single container, there is a problem that the cosmetics are easily deteriorated by external factors such as ultraviolet rays or are easily affected by external impacts.

[0009] In the case of a pump-type cosmetic container, it includes: a container body that contains contents; a squeeze pump disposed in an opening of the container body and operated by squeezing; and a nozzle head connected to the upper part of the container body in connection with the squeeze pump. When the nozzle head, exposed to the outside, is squeezed downwards, a certain amount of the contents contained in the container body is expelled to the outside by the pumping operation of the squeeze pump. The advantages of this type of pump-type cosmetic container are that the contents contained in the container body do not come into contact with outside air, and excessive discharge of contents through the nozzle outlet is prevented. Furthermore, they are convenient to use because they can be operated even when the container body is placed on the floor.

[0010] However, in pump-type cosmetic containers, the pump consists of multiple components that operate organically together, resulting in a complex structure and an increased number of parts. This leads to increased assembly processes, time, and manufacturing costs, and also presents the problem of dispensing operations not being able to proceed smoothly due to manufacturing tolerances and malfunctions during use.

[0011] To address the aforementioned problems, Korean Utility Model 20-0464780 discloses a dual-structure storage container with a pumping function via a check valve. This conventional technology relates to a dual-structure storage container for storing, discharging, and using contents, comprising a resilient tube and a bag containing the contents inside the tube. A nozzle cap with a discharge port is connected to an upper connection. The tube is equipped with a suction check valve and a discharge valve. The suction check valve draws in external air when the tube is squeezed, while the discharge valve discharges the contents to the outside by squeezing the bag into the discharge port of the nozzle cap. This allows the bag to be gradually compressed to discharge the contents through tube compression and pumping operations. Therefore, the discharge and use of the contents are facilitated, and the risk of spoilage due to contact with air is prevented.

[0012] However, in this conventional technology, the suction check valve is exposed to the outside, so when outside air is drawn into the container through the suction check valve, foreign objects are introduced along with it, causing unsanitary problems.

[0013] In addition, in the structure of this conventional technology, the tube and bag are sealed and joined as a whole, and the nozzle cap with the discharge hole is assembled and connected to the inside of the opening of the tube and bag. The problem with this structure is that the space between the tube and bag and the nozzle cap widens due to the continuous pressure of the tube, resulting in a decrease in the adhesion and sealing force between the components.

[0033] Beneficial effects

[0034] According to one aspect of the invention, a container for discharging liquid contents is provided, the container being provided with a discharge valve that opens and closes a discharge passage by the discharge pressure of the liquid contents and an air inlet valve that opens and closes an air inlet in response to pressure changes within the container. This allows each valve to operate selectively when the container is squeezed or released, thereby contributing to easy discharge of the liquid contents and the maintenance of a seal and stable pressure within the container.

[0035] According to one aspect of the invention, the sealing frame is inserted into the opening side of the outer container, and the sealing frame is surrounded by a shoulder, such that the air inlet and air valve of the sealing frame are placed inside the outer container, which prevents foreign matter from entering due to external exposure, thereby making it more hygienic to use.

Therefore, the terminology used in this invention is defined according to its meaning in relation to the content discussed throughout the specification, rather than according to its simplistic meaning.

[0048] When a component “includes” a certain element, it cannot be interpreted as excluding other elements unless specifically stated otherwise. Instead, it may include other elements.

[0049] In the following description, a container for discharging liquid contents according to one aspect of the present invention will be described in detail with reference to the accompanying drawings.

[0050] Figure 1 This is a perspective view of a container for discharging liquid contents according to one aspect of the present invention. Figure 2 This is an exploded perspective view of a container for discharging liquid contents according to one aspect of the present invention, and Figure 3 This is a cross-sectional view of a container for discharging liquid contents according to one aspect of the present invention.

[0051] As shown in the figure, a container for discharging liquid contents according to one aspect of the present invention includes an inner container (10), an outer container (20), a sealing frame (30), an air inlet valve (40), a shoulder (50), a nozzle (60), and a discharge valve (70).

[0052] The container for discharging liquid contents according to one aspect of the present invention will be described separately for each component as follows.

[0053] The inner container (10) is a storage container for storing liquid contents, and its interior is maintained under vacuum to safely store the liquid contents. The liquid contents may include all contents in liquid or gel form, such as cosmetics, shampoos, or soaps. In this case, the inner container (10) is preferably a pouch-shaped container whose shape changes as the liquid contents contained therein are consumed.

[0054] The inner container (10) may consist of a soft receiving part (12) that holds liquid contents inside and a rigid connecting part (14) that engages with the receiving part (12) and is used to connect to the sealing frame (30).

[0055] like Figure 2 As shown, an inlet (14a) is formed on one side of the connecting portion (14), wherein the inlet (14a) passes through the center of the sealing frame (30). Liquid contents are injected through the inlet (14a). A connecting portion (14b) is provided on the opposite side of the inlet (14a), and the receiving portion (12) engages with it while surrounding the connecting portion (14b). Moreover, on the outer periphery of the inlet (14a), a first fastening protrusion (14c) protrudes and can be detachably connected to the sealing frame (30). At the same time, a locking protrusion (14d) protrudes outward between the inlet (14a) and the connecting portion (14b) of the connecting portion (14), so that it can be locked on the lower surface of the sealing frame (30). Therefore, the inner container (10) will not flow to the upper side of the sealing frame (30), and the upper surface of the locking protrusion (14d) contacts the lower surface of the sealing frame (30), thereby increasing the sealing force inside the outer container (20).

[0056] The outer container (20) protects the inner container (10) by surrounding the outer side of the inner container (10). The outer container (20) is in the form of a rigid elliptical cylinder with an opening on one side, and forms the appearance of a container for discharging liquid contents. Of course, the outer container (20) is not limited to an elliptical cylinder shape, and can be formed in various shapes or made of various materials, taking into account the type of stored contents, availability, design factors, etc. Preferably, the outer container (20) is narrow, long, and has a flat bottom so that the user can easily hold it in their hand and easily stand it upright on the floor.

[0057] like Figure 3As shown, a protrusion is formed on the upper outer periphery of the outer container (20), which can be fixedly connected to a protrusion formed on the inner periphery of the shoulder (50). In this case, considering the ease of connection and assembly between the components, the protrusion formed on the outer container (20) can be partially formed on the outer periphery of the outer container (20), or it can be formed entirely along the circumference of the outer container (20). In the drawings of a container for discharging liquid contents according to one aspect of the invention, the outer container (20) and the shoulder (50) are shown as interlocking, but this is not limited to this, and various connection methods are possible, such as a connection of protrusions and grooves, a force-fit connection, or adhesion.

[0058] The sealing frame (30) blocks the open side of the outer container (20) to seal the interior of the outer container (20). Figure 2 As shown, the sealing frame (30) is formed as a three-dimensional ring with a certain space on its upper inner side, and at least a part of it can be inserted into the opening of the outer container (20).

[0059] The sealing frame (30) may consist of a bottom surface (32), an inner wall (34) extending upward from the bottom surface (32), and an outer wall (36) spaced apart from the outer side of the inner wall (34) at a predetermined distance.

[0060] In the inner wall (34) of the sealing frame (30), a second fastening protrusion (34a) protrudes toward the center portion, wherein the second fastening protrusion (34a) is detachably connected to the first fastening protrusion (14c), wherein a through hole is formed on the inner side of the inner wall (34) so ​​that the entrance (14a) of the inner container (10) can pass through it.

[0061] The outer wall (36) of the sealing frame (30) is in close contact with the upper inner periphery of the outer container (20), and the mounting bend (36a) extends outward from the outer wall (36) and can thus be assembled and connected to the top of the outer container (20). The mounting bend (36a) can be composed of a first mounting bend (36a-1) and a second mounting bend (36a-2). The first mounting bend (36a-1) is formed extending outward from the outer wall (36) and is located on the top of the outer container (20). The second mounting bend (36a-2) is formed extending toward the lower side of the first mounting bend (36a-1) and is in close contact with the upper outer periphery of the outer container (20). At this time, the first mounting bend (36a-1) of the mounting bend (36a) can be stably fixed because its top is pressed by the shoulder (50). In other words, preferably, the assembly bend (36a) has an annular shape integrally connected to the outer side of the sealing frame (30), so that it can hook and fix to the upper part of the outer container (20).

[0062] Meanwhile, the sealing frame (30) may be provided with an air inlet (38), which introduces external air according to changes in the internal pressure of the outer container (20). Figure 3 As shown, the sealing frame (30) is provided with a protrusion (32a) extending upward from the bottom surface (32). The protrusion (32a) has a certain height, its lower part is open, and its upper surface is provided with an air inlet (38). The air intake valve (40) is inserted into the internal space of the protrusion through the lower part of the opening of the protrusion (32a), thereby improving the connection stability, assembly ease and space utilization of the air intake valve (40).

[0063] An intake duct (38a) may be formed on one side of the intake port (38) in an upward extending manner, and a valve insertion slot (38b) for the intake valve (40) to be inserted may be formed on the other side. The intake duct (38a) extends vertically from the upper surface of the protrusion (32a) of the sealing frame (30) to form the sidewall of the intake port (38), and is located in the space surrounded by the inner wall (34) and outer wall (36) of the sealing frame (30) and the shoulder (50). That is, in a conventional container, the intake port is exposed to the outside, and thus when outside air is drawn into the container through the intake port, foreign matter is introduced along with it, resulting in hygiene problems. Therefore, in a container for discharging liquid contents according to one aspect of the invention, an air inlet (38) and an air inlet valve (40) are disposed in the internal space of the container between a sealing frame (30) and a shoulder (50) so that they are not exposed to the outside, and an air inlet duct (38a) is disposed outside the air inlet (38) to prevent foreign matter from flowing into the air inlet (38), thereby making it more hygienic to use.

[0064] Simultaneously, at least one vent (39) may be formed at the upper end of the edge of the sealing frame (30). Figure 2 and Figure 3 As shown, the vent (39) is a groove that passes through the outer upper surface of the sealing frame (30) and connects the outer space and the inner space of the sealing frame (30). It serves as a channel for introducing external air that has passed through the gap between the upper outer periphery of the outer container (20) and the lower inner periphery of the shoulder (50) into the air inlet (38).

[0065] An air inlet valve (40) is installed in the sealing frame (30) and selectively opens and closes the air inlet (38) in response to pressure changes inside the outer container (20). In other words, when the outer container (20) is squeezed, the air inlet valve (40) blocks the air inlet (38) of the sealing frame (30); and when the outer container (20) is released, the air inlet valve opens the air inlet (38) due to the vacuum pressure generated inside the outer container (20), and at the same time, as external air flows into the air inlet (38), the outer container (20) returns to its original shape. Here, the air inlet valve (40) is installed such that its central portion can move flexibly along the direction of external air inflow.

[0066] As described above, the intake valve (40) is inserted into and fixedly connected to the internal space of the protrusion (32a) formed in the sealing frame (30) through the lower part of the opening, that is, inserted into and fixedly connected to the valve insertion groove (38b), so that the exposure of the intake valve (40) can be minimized. Here, the intake valve (40) is preferably a disc valve.

[0067] The shoulder (50) is connected to one side of the outer container (20) while surrounding the sealing frame (30). For design continuity, preferably, the lower part of the shoulder (50) is in the form of an elliptical cylinder with the same width as the outer container (20), and the upper part is in the form of a cylinder or elliptical cylinder that is narrower than the lower part.

[0068] An outlet channel (52) may be formed at the center of the interior of the shoulder (50) for the liquid contents contained in the inner container (10) to pass through. At this time, the outlet channel (52) is connected to the inlet (14a) of the inner container (10) and may extend appropriately in the same direction as the inlet (14a) to smoothly discharge the liquid contents.

[0069] like Figure 3As shown, a first tight-contact protrusion (51) and a second tight-contact protrusion (53) located at a predetermined distance outside the first tight-contact protrusion (51) are provided at the lower part of the shoulder (50). The second tight-contact protrusion (51) and the second tight-contact protrusion (53) can tightly contact both sides of the connection portion between the inner container (10) and the sealing frame (30). More specifically, the first tight-contact protrusion (51) is in tight contact with the inner periphery of the inlet (14a) of the inner container (10) due to insertion into the inlet (14a), and the second tight-contact protrusion (53) is in tight contact with the outer periphery of the inner wall (34) of the sealing frame (30). Therefore, the inlet (14a) and the inner wall (34) are inserted together between the first tight contact protrusion (51) and the second tight contact protrusion (53) and are thus not separated, thereby stably maintaining the connection between the inner container (10) and the sealing frame (30), namely the connection between the first fastening protrusion (14c) and the second fastening protrusion (34a).

[0070] Simultaneously, a soft sealing ring (54) is formed between the first tight contact protrusion (51) and the second tight contact protrusion (53), and tightly contacts the upper end of the inlet (14a) of the inner container (10) and the upper end of the inner wall (34) of the sealing frame (30), thereby maintaining the sealing force within the outer container (20). Here, to provide the sealing force, the sealing ring (54) is made of an elastic material, preferably one of polyurethane rubber, natural rubber, elastomer, NBR (nitrile rubber), or silicone resin, or polypropylene, polyethylene, or elastic ABS (acrylonitrile-butadiene-styrene) material. In particular, TPE (thermoplastic elastomer) is the most desirable material, as it is a material between soft rubber and plastic with excellent durability.

[0071] The first upper extension protrusion (55) extends upward in the upper inner part of the shoulder (50), and the second upper extension protrusion (57) spaced at a predetermined distance from the outer side of the first upper extension protrusion (55) can extend upward. Here, the nozzle (60) is fixedly connected to the inner periphery of the second upper extension protrusion (57).

[0072] The first upper extension protrusion (55) is a portion for inserting and setting the discharge valve (70), which will be described later. The outer periphery of the discharge valve (70) is in close contact with the inner periphery of the first upper extension protrusion (55) to prevent horizontal flow of the discharge valve (70). At least one valve seat (55a) is formed inside the first upper extension protrusion (55), such that the edge of the discharge valve (70) can be located on top of the valve seat. Ideally, the valve seats (55a) are spaced at predetermined intervals and extend vertically along the circumference of the inner periphery of the first upper extension protrusion (55). Furthermore, a third upper extension protrusion (59) can be formed to be spaced at predetermined intervals from the inner side of the first upper extension protrusion (55) and can extend upwards. The third upper extension protrusion (59) forms the outer wall of the discharge passage (52), while the central portion of the discharge valve (70) is located on top of the third upper extension protrusion.

[0073] Simultaneously, a shoulder cover (80) is formed on one side of the shoulder (50) to open and close the outlet (62) of the nozzle (60). The shoulder cover (80) is integrally hinged to the shoulder (50) and rotates at a certain angle to open or close the outlet (62) of the nozzle (60). Of course, the shoulder cover (80) can be formed separately from the shoulder (50) and hinged to one side of the shoulder (50). Furthermore, a sealing protrusion (82) can be formed as annular protrusions on the inner upper surface of the shoulder cover (80), wherein when the shoulder cover (80) is closed, the sealing protrusion (82) is inserted simultaneously around the end of the nozzle (60), thereby sealing the outlet (62).

[0074] The nozzle (60) is fixedly connected to one side of the shoulder (50) by at least a portion of it being inserted into the shoulder. A discharge port (62) is formed at the center of the nozzle (60) for discharging liquid contents to the outside, wherein the discharge port (62) is temporarily connected to or blocked by the discharge passage (52) of the shoulder (50) by a discharge valve (70).

[0075] like Figure 3 As shown, the nozzle (60) is provided with a first downwardly extending protrusion (61) and a second downwardly extending protrusion (63) spaced apart from the outer side of the first downwardly extending protrusion (61) and extending downward. The first downwardly extending protrusion (61) is inserted into close contact with the outer periphery of the first upwardly extending protrusion (55) of the shoulder (50), and the second downwardly extending protrusion (63) is fixedly connected to the inner periphery of the second upwardly extending protrusion (57) of the shoulder (50).

[0076] Meanwhile, the valve fixing protrusion (64) extends downward inside the nozzle (60), and when the shoulder (50) and the nozzle (60) are connected, the valve fixing protrusion (64) presses and fixes the upper end of the discharge valve (70) located inside the shoulder (50). Therefore, the discharge valve (70) can be fixed and does not move between the shoulder (50) and the nozzle (60).

[0077] A discharge valve (70) is installed in the shoulder (50) and selectively opens and closes the discharge passage (52) of the shoulder (50) according to pressure changes within the outer container (20). In other words, when the outer container (20) is squeezed, the discharge valve (70) is pushed up by the discharge pressure generated within the inner container (10) to open the discharge passage (52) to discharge the contents that have moved into the discharge passage (52) to the discharge outlet (60), and when the outer container (20) is released, the outer container (20) returns to its original shape by elastic restoring force and blocks the discharge passage (52). At this time, the discharge valve (70) is installed such that its central portion can move flexibly along the discharge direction of the liquid contents.

[0078] As described above, the discharge valve (70) is disposed between the shoulder (50) and the nozzle (60), wherein the outer periphery of the discharge valve (70) is in close contact with the inner periphery of the first upper extension protrusion (55), the edge of the discharge valve is located on the upper end of the valve seat (55a), and the top is pressed and fixed by the valve fixing protrusion (64). Here, it is desirable that the discharge valve (70) is a disc valve.

[0079] As described above, the container for discharging liquid contents according to one aspect of the present invention is provided with a discharge valve (70) and an air inlet valve (40), wherein the discharge valve (70) opens and closes the discharge channel (52) by the discharge pressure of the liquid contents, and the air inlet valve (40) opens and closes the air inlet (38) according to the change in internal pressure of the outer container (20). This allows each valve to be selectively operated when the outer container (20) is squeezed or released, thereby facilitating the discharge of liquid contents and stably maintaining the opening and closing of the container and the pressure inside the container, and ensuring the smooth discharge of liquid contents and the outer container (20). Furthermore, by simplifying the opening and closing of the discharge channel (52) and the air inlet (38) by squeezing and releasing the outer container (20) and the sealing structure inside the outer container (20), the manufacturing process can be simplified and productivity can be improved by reducing manufacturing costs.

[0080] Figures 4 to 7 The figures illustrate the operation of a container for discharging liquid contents according to one aspect of the present invention, and the operation of the container for discharging liquid contents according to one aspect of the present invention is explained with reference to these figures.

[0081] Figure 4 This is a cross-sectional view showing the outer container under compression according to one aspect of the invention. Figure 5 yes Figure 4 A magnified view of a portion of the image. Figure 6 This is a cross-sectional view showing the outer container in a released state according to one aspect of the invention. Figure 7 yes Figure 6 A magnified view of a portion of the image.

[0082] In order to use the container for discharging liquid contents according to one aspect of the invention, first unscrew the shoulder cap (80) from the shoulder (50) to open the outlet (62) of the nozzle (60).

[0083] After that, as Figure 4 As shown, when one side of the outer container (20) is squeezed, the inner container (10) located inside the outer container (20) is also squeezed, thereby generating pressure within the inner container, and the liquid contents contained in the inner container (10) move through the inlet (14a) into the discharge channel (52). Meanwhile, as... Figure 5 As shown, the discharge valve (70) is pushed up by the discharge pressure of the liquid contents in the discharge channel (52), so the discharge channel (52) of the shoulder (50) opens, which allows the liquid contents to be discharged to the outside through the discharge port (62). At this time, the air inlet (38) of the sealing frame (30) remains closed by the air inlet valve (40).

[0084] After that, as Figure 6 As shown, when the outer container (20) is released to one side, the discharge valve (70) returns to its original shape, thereby closing the discharge port (62) of the nozzle (60). Simultaneously, as... Figure 7 As shown, due to the vacuum pressure generated inside the outer container (20) pulling the air inlet valve (70), the air inlet (38) of the sealing frame (30) is opened, and when external air enters the gap between the outer container (20) and the shoulder (50) and the vent (39) and flows into the interior of the outer container (20) through the air inlet (38), the outer container (20) returns to its original shape.
