Description

Technical Field

[0001] The present invention relates to a container for ejecting a liquid, in which the passage structure for discharging the content is improved. Background Art

[0002] In a cosmetic container or the like, a pump is coupled to the upper inlet of a container for storing a liquid content such as perfume, and functions to eject and discharge a fixed amount of the content to the outside. When a user presses down on a nozzle corresponding to a button in order to eject the liquid content, the content flowing into the inside of the pump is pressurized, rises along the discharge passage, and is ejected through the nozzle. Then, when the pressurization on the nozzle is released, the discharge passage is mechanically closed as the nozzle rises, and as the pressure inside the pump decreases, the content flows in from the container to replenish it.

[0003] Such pumps are used for ejecting various contents such as perfume, cosmetics, air fresheners, and insecticides. In particular, since a fixed amount of the content can be discharged by pressing the nozzle once and the content is not exposed to the outside, it is convenient to use, and thus the demand for it is continuously increasing. Korean Patent No. 1963619 and the like disclose a conventional pump and a general structure of a container combined with the pump.

[0004] On the other hand, in order to discharge the content from the main body (body) storing the content, the pump is connected to a hose having a relatively long length, and the lower end of the hose is in contact with the bottom surface of the main body. The suction force of the pump is transmitted to the hose, so that the content stored in the main body flows into the pump through the hose. Although such a hose allows all of the content stored in the main body to be used, it is inserted into the inside of the main body and is visible from the outside, so it becomes a factor that reduces the aesthetic appearance of the main body. In particular, when the main body corresponds to a cosmetic container, this problem of reducing the aesthetic appearance is more prominent. Therefore, in a container using a pump, in order to prevent the hose from being exposed to the outside, the main body is often made of an opaque material. Summary of the Invention

[0005] Technical Problem

[0006] Therefore, the present invention is proposed to solve the above problems, and an object thereof is to provide a container for ejecting a liquid that can remove the hose by improving the passage structure for discharging the content.

[0007] Technical Solution

[0008] A container for ejecting a liquid according to one aspect of the present invention includes: a main body which is divided into a filling space and a main body outflow passage by a partition provided therein along the longitudinal direction, a lower main body hole corresponding to an inlet of the main body outflow passage is formed at a lower portion of the partition, and an upper main body hole corresponding to an outlet of the main body outflow passage is formed at an upper portion of the partition; a main body cap which is coupled to an upper portion of the main body and has a cap passage communicating with the upper main body hole and a pump insertion space communicating with the cap passage and into which a pump is inserted; and a pump support which is coupled to an upper portion of the main body cap, supports the pump, and prevents external air from flowing into the pump insertion space.

[0009] The container of the present invention may have one or more of the following embodiments. For example, it may further include a shoulder coupled to an upper portion of the pump support to press the pump downward.

[0010] Spaced protrusions may be formed on a bottom surface of the pump insertion space to form a spacing between the pump and the bottom surface.

[0011] A counterweight that reduces its cross-section may be inserted inside the outflow passage.

[0012] An upper portion of the main body may be provided with a coupling surface on which the upper main body hole is formed, a center hole into which the pump insertion space is inserted is formed on the coupling surface, and a main body protrusion that internally accommodates the upper main body hole may be formed on one side of the center hole.

[0013] The main body cap may have a passage protrusion that is inserted inside the main body protrusion and communicates with the cap passage.

[0014] The pump support may have a close-contact protrusion that closely contacts the periphery of the pump.

[0015] The main body may have a cross-section in the shape of one of a triangle, a quadrilateral, a circle, and an ellipse.

[0016] It may be that the shoulder has a locking protrusion that presses the pump downward, a shoulder air hole is formed on the locking protrusion, a support air groove communicating with the shoulder air hole is formed on the pump support, and an air nozzle communicating with the support air groove is formed on the main body, and the air nozzle communicates with the filling space.

[0017] The main body cap may have an intake protrusion into which the air nozzle is inserted.

[0018] A base may be coupled to a lower portion of the main body. Additionally, it may further include a pump for discharging the content.

[0032] The present invention can be variously modified and can have various embodiments. Specific embodiments will be illustrated in the drawings and described in detail in the detailed description. However, this is not to limit the present invention to a specific embodiment, but should be understood to include all modifications, equivalents, and alternatives falling within the spirit and technical scope of the present invention. When it is judged that a detailed description of related well-known technologies may obscure the gist of the present invention during the description of the present invention, its detailed description is omitted.

[0033] The terms used in this application are only for describing specific embodiments and are not intended to limit the present invention. Unless otherwise clearly defined in the context, singular expressions include plural expressions. In this application, terms such as "including" or "having" should be understood as aiming to specify the existence or additional possibility of features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, rather than precluding the existence or additional possibility of one or more other features or numbers, steps, actions, components, parts, or combinations thereof.

[0034] Terms such as first, second, etc. may be used to describe various components, but these components should not be limited by these terms. These terms are only for the purpose of distinguishing one component from another.

[0035] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. When describing with reference to the accompanying drawings, regardless of the reference numerals, the same or corresponding components are given the same reference numerals, and repeated descriptions thereof are omitted.

[0036] The container for ejecting liquid in this embodiment can eject various liquids such as cosmetics, perfumes, shampoos, various detergents, disinfectants, and medicines, and is not limited by the type and nature of the content to be ejected.

[0037] Figure 1 is a perspective view of the container 100 for ejecting liquid according to the first embodiment of the present invention. In addition, Figure 2 is Figure 1 a central longitudinal sectional view along AA, Figure 3 is a sectional view in Figure 2 with the pump 230 removed. For reference, Figure 3 the arrows shown illustrate the discharge flow direction of the content.

[0038] Referring to Figures 1 to 3 , the container 100 of this embodiment is characterized in that the hose in the filling space 112 of the main body 110 for storing the content (not shown) is removed, and a passage for discharging the content is formed on the side of the main body 110 by a partition 114 or the like. Therefore, the container 100 of this embodiment can simplify the structure. Even if the material of the main body 110 is transparent, the internal hose is not visible, so the aesthetic feeling of the container can be further improved.

[0039] The container 100 of this embodiment includes a main body 110, a main body cap 150, a pump support 170, a shoulder 200, a nozzle cap 220, a pump 230, and an upper cap 250.

[0040] The upper cap 250 has a hollow column shape and has a structure with an open lower part. The upper cap 250 is coupled around the 200 to cover the nozzle cap 220.

[0041] The nozzle cap 220 is inserted inside the shoulder 200, and the nozzle 222 provided inside it is combined with the valve 234 of the pump 230 through a separate component (not shown). Since the valve 234 is elastically supported by a spring (not shown), when the external force is released, the nozzle cap 220 can also rise by the elastic force. The content that has passed through the valve 234 of the pump 230 can be discharged to the outside of the container 100 through the nozzle 222.

[0042] The lower part of the pump 230 is inserted into the pump insertion space 154 formed in the main body cover 150, and the outer shell 232 is downwardly pressed by the locking protrusion 214 of the shoulder 200 to fix the position. The pump 230 allows the content to flow into the inside of the pump insertion space 154, and can suck the inflowing content into its inside and discharge it through the nozzle 222.

[0043] The pump 230 includes an outer shell 232, a valve 234, an outer shell cap 236, a piston 238, a guide 240, and a disk 242, which is the same as or similar to the pump structure described in Korean Patent No. 1963619, so its detailed description will be omitted.

[0044] Figure 4 and Figure 5 is Figure 1 a perspective view of the main body 110 of the illustrated container 100.

[0045] Reference Figures 2 to 5 , the main body 110 has a filling space 112 for storing the content, and the filling space 112 is separated from the main body outflow passage 113 by a partition 114. The partition 114 is formed along the length direction of the main body 110 and can be formed on the inner edge portion of the main body 110. A lower main body hole 116 is formed at the lower end of the partition 114, whereby the content in the filling space 112 can flow into the main body outflow passage 113.

[0046] The main body outflow passage 113 has a smaller cross-sectional area than the filling space 112 and corresponds to the passage for the content to move upward. That is, through the operation of the pump 230, the content flows into the main body outflow passage 113 through the lower main body hole 116 and rises, and flows into the pump insertion space 154 through the upper main body hole 126 and the cover passage 158. Thus, the main body outflow passage 113 is provided on one side of the main body 110 to provide a passage for the content to move.

[0047] Inside the main body outflow passage 113, a counterweight 140 can be inserted. The counterweight 140 can have a cross-section that is the same as but slightly smaller than the cross-sectional shape of the main body outflow passage 113. By inserting the counterweight 140 inside the main body outflow passage 113, a fine passage for the content to move can be formed.

[0048] When the cross-sectional area of the main body outflow passage 113 is small enough, the counterweight 140 may not be inserted.

[0049] The main body 110 of the container 100 of this embodiment is illustrated as having a substantially triangular cross-section, but the present invention is not limited by the cross-sectional shape of the main body 110. Therefore, in another embodiment of the present invention, the main body may have various cross-sectional shapes including a circle, a polygon such as a quadrilateral, an ellipse, etc.

[0050] A coupling surface 118 may be formed at the upper part of the main body 110, and the lower part of the main body 110 may have an open structure. A center hole 120 and a center protrusion 122 are formed at the center of the coupling surface 118, and an air nozzle 132 and a main body protrusion 125 are formed on one side thereof. The coupling surface 118 is formed slightly spaced apart from the upper end of the main body 110. Therefore, the upper part of the main body 110 has a recessed shape through the coupling surface 118, and the main body cover 150, the pump support 170, and the shoulder 200 are sequentially inserted into the inside thereof.

[0051] A center hole 120 and a center protrusion 122 are formed at the center of the coupling surface 118. The center hole 120 is formed inside the center protrusion 122. In addition, the pump insertion space 154 of the main body cover 150 is inserted into the inside of the center protrusion 122. The content does not discharge through the center hole 120, and the center hole 120 can achieve fixing the position of the main body cover 150 and coupling it to the main body 110.

[0052] The main body protrusion 125 has a hollow cylindrical shape with an open upper part and a lower part closed by the coupling surface 118. In addition, an upper main body hole 126 is formed on the coupling surface 118 located inside the main body protrusion 125. In addition, a passage protrusion 162 formed on the lower surface of the main body cover 150 is inserted into the inside of the main body protrusion 125 and communicated. Thus, the main body protrusion 125 corresponds to the part connecting the upper main body hole 126 corresponding to the passage for the content to flow out and the cover passage 158, and it has a certain internal space, thereby constantly restricting the volume of the outflow passage and forming a closed outflow passage.

[0053] On the inner circumferential surface of the upper part of the main body 110, a coupling groove 130 may be formed in the entire circumference. The coupling protrusion 206 formed on the outer circumferential surface of the shoulder 200 is inserted into the coupling groove 130, so the shoulder 200 is coupled to the upper part of the main body 110.

[0054] The air nozzle 132 has a hollow cylindrical shape, and its lower end communicates with the filling space 112. Through the air nozzle 132, external air can flow into the inside of the filling space 112, so the pressure drop in the filling space 112 is prevented and maintained at atmospheric pressure. The air nozzle 132 is inserted into the intake protrusion 167 formed on the main body cover 150, and its upper end is open.

[0055] Figure 6 It is a perspective view illustrating the base 134.

[0056] Reference Figures 2 to 3 and Figure 6 , the base 134 can be coupled to the open lower part of the main body 110. The base 134 can correspond to a plate that has the same cross-section as the main body 110 and is formed thinner. An insertion groove 136 is formed on the base 134, and the lower protrusion 142 of the counterweight 140 can be inserted into the insertion groove 136. In addition, the base 134 can be fixedly coupled to the lower part of the main body 110 by bonding or welding or the like.

[0057] Figure 7 It is a perspective view illustrating the counterweight 140.

[0058] Reference Figures 2 to 3 and Figure 7 , the counterweight 140 has the same shape as the main body outflow passage 113 and a cross-section with a slightly smaller size. In addition, an upper groove 144 is formed on the upper part of the counterweight 140, which can be formed to facilitate the smooth flow of the content through the upper body hole 126. In addition, the lower protrusion 142 formed on the lower part of the counterweight 140 is inserted into the insertion groove 136 of the base 134, so that the counterweight 140 can be stably coupled to the inside of the main body outflow passage 113.

[0059] Figure 8 and Figure 9 They are a perspective view and a perspective cross-sectional view illustrating the main body cover 150.

[0060] Reference Figures 2 to 3 and Figures 8 to 9 , the main body cover 150 is coupled to the upper part of the main body 110, and a pump support member 170 and a shoulder 200 are sequentially coupled to its upper part. The main body cover 150 includes a cover surface 152 having the same shape as the cross-section of the main body 110, and an annular upper circumferential surface 164 that protrudes upward from one surface of the cover surface 152 and is open at the upper part. In addition, a pump insertion space 154, a cover passage 158, a fixing protrusion 163, and an air intake protrusion 167 are provided inside the upper circumferential surface 164. In addition, a passage protrusion 162 protrudes downward on the lower surface of the cover surface 152.

[0061] The pump insertion space 154 is a groove formed recessedly in the center of the cover surface 152 and has a circular cross-section. The housing 232 of the pump 230 is inserted into the inside of the pump insertion space 154. In addition, a hole (not labeled) is formed on the lower surface of the housing 232, and the content flowing into the pump insertion space 154 flows into the inside of the housing 232 through the hole on the lower surface of the housing 232.

[0062] The pump insertion space 154 protrudes downward from the cover surface 152, and this part is inserted inside the central protrusion 122 of the main body 110.

[0063] One side of the upper part of the pump insertion space 154 communicates with the cover passage 158. Therefore, the content flowing in through the cover passage 158 descends to the bottom surface of the pump insertion space 154 and flows into the interior of the housing 232.

[0064] A plurality of spaced protrusions 156 can be circularly arranged on the bottom surface of the pump insertion space 154. The spaced protrusions 156 have a predetermined height, and the plurality of spaced protrusions 156 can be arranged at a predetermined interval from each other. The housing 232 of the pump 230 abuts against the spaced protrusions 156 and is spaced from the bottom surface of the pump insertion space 154 by a distance corresponding to its height. Therefore, the content flowing into the pump insertion space 154 can flow into the interior of the housing 232 through the space formed between the spaced protrusions 156.

[0065] A cover passage 158 having a predetermined width and depth is horizontally formed on the cover surface 152. The cover passage 158 can have a quadrangular cross-section, one end communicates with the cover inflow hole 160, and the other end communicates with the pump insertion space 154. In addition, the cover passage 158 is defined by a bottom surface and two side surfaces, and its open upper part is closed by the pump support 170.

[0066] The cover inflow hole 160 formed at one end of the cover passage 158 penetrates the cover surface 152 and communicates with the internal space of the passage protrusion 162.

[0067] The passage protrusion 162 protrudes from the lower surface of the cover surface 152 and has a hollow cylindrical shape, and its lower end portion has an open structure. In addition, the upper end portion of the passage protrusion 162 is closed by the cover surface 152 and communicates with the cover passage 158 only through the cover inflow hole 160. The passage protrusion 162 is inserted into the interior of the main body protrusion 125 formed on the upper part of the main body 110.

[0068] Two fixing protrusions 163 are formed on the cover surface 152, and the two fixing protrusions 163 and an air intake protrusion 167 can be arranged in an equilateral triangle shape. The fixing protrusions 163 are respectively inserted into two second insertion grooves 188 formed in the lower part of the pump support 170, so that the pump support 170 is coupled to the upper part of the main body cover 150.

[0069] A coupling protrusion 166 is formed on the outer peripheral surface of the upper circumferential surface 164. When the pump support 170 is coupled to the upper part of the main body cover 150, the outer part of the upper circumferential surface 164 is inserted into the coupling groove 176 formed between the outer circumferential surface 172 and the inner circumferential surface 174 of the pump support 170. At this time, the coupling protrusion 166 can be inserted into a groove (not shown) formed on the inner circumferential surface of the outer circumferential surface 172.

[0070] Inside the upper circumferential surface 164, an intake protrusion 167 having a hollow cylindrical shape is formed. The upper and lower ends of the intake protrusion 167 are both open, and the air nozzle 132 of the main body 110 is inserted therein. Through the open upper end portion of the air nozzle 132, air can flow into the inside of the filling space 112 of the main body 110.

[0071] Figure 10 and Figure 11 are a perspective view and a perspective cross-sectional view illustrating the pump support member 170.

[0072] Reference Figures 2 to 3 and Figures 10 to 11 , the pump support member 170 is coupled to the upper part of the main body cover 150 to stably support the pump 230 and prevent external air from flowing into the inside of the pump insertion space 154. The pump support member 170 includes a support body 180 having a hollow cylindrical shape provided at the center, and an outer circumferential surface 172 and an inner circumferential surface 174 formed around it.

[0073] The outer circumferential surface 172 and the inner circumferential surface 174 have an annular cross-section, and a coupling groove 176 corresponding to the spacing is formed therebetween. The upper circumferential surface 164 of the main body cover 150 is inserted into the coupling groove 176 by press fitting. In addition, an installation step 178 is formed at the upper part of the outer circumferential surface 172, and the upper surface thereof is downwardly pressed by a pressing protrusion 208 provided inside the shoulder 200.

[0074] The support body 180 is located inside the inner circumferential surface 174 and has a height higher than that of the inner circumferential surface 174. An outer body locking groove 182 is formed on the outer circumferential surface of the support body 180, and an inner coupling protrusion 212 formed inside the shoulder 200 is inserted into the inside of the outer body locking groove 182. Through the outer body locking groove 182 and the inner coupling protrusion 212, the shoulder 200 is stably coupled to the pump support member 170.

[0075] The housing 232 of the pump 230 is inserted into the empty space inside the support body 180. In addition, an annular pressing protrusion 192 is formed on the lower inner circumferential surface of the support body 180. The pressing protrusion 192 presses and adheres to the outer circumferential surface of the housing 232 of the pump 230, so that external air does not flow into the inside of the pump insertion space 154.

[0076] On the inner circumferential surface of the support body 180, a support air groove 190 having a predetermined length is formed along the length direction starting from its upper end. A predetermined spacing is formed between the support air groove 190 and the housing 232 of the pump 230, and through the spacing, air flows into the upper end portion of the air nozzle 132 of the main body 110.

[0077] An annular empty space is formed between the inner circumferential surface 174 and the support body 180, in which a first insertion groove 186 and two second insertion grooves 188 having respective upper surfaces 187, 189 are formed. The first insertion groove 186 and the second insertion groove 188 correspond to an empty space whose upper portion is closed by the upper surfaces 187, 189 and whose lower portion is open.

[0078] The air intake protrusion 167 formed on the body cover 150 is inserted into the first insertion groove 186. In addition, since the upper end of the air intake protrusion 167 is not connected to the upper surface 187, a passage is formed therebetween so that air can move. In addition, the fixing protrusion 163 is inserted into the inside of the second insertion groove 188, so that the pump support 170 can be stably combined with the upper part of the body cover 150.

[0079] Figure 12 and Figure 13 1 and 2 are a perspective view and a perspective cross-sectional view illustrating the shoulder 200 .

[0080] refer to Figures 2 to 3 as well as Figures 12 to 13 The shoulder 200 is coupled to the upper portion of the pump support 170 to pressurize the pump 230 downward, and the nozzle cap 220 is coupled to the upper portion thereof. The shoulder 200 includes a pump coupling portion 210 in a hollow cylindrical shape, and a body coupling portion 202 formed around the pump coupling portion and only opened at the lower portion.

[0081] The body joint part 202 has a joint circumferential surface 204 which is inserted into the groove portion formed by the joint surface 118 at the upper portion of the body 110, which is the same as described above. In addition, since the lower portion of the body joint part 202 is open, the body cover 150 and the pump support 170 are accommodated therein.

[0082] The body coupling portion 202 has an upper surface (no reference numeral), and the upper surface has the same shape as the cross section of the body 110. In addition, the pump coupling portion 210 is protrudingly formed at the center of the upper surface. In addition, a pressurizing protrusion 208 is protrudingly formed on the upper surface from the inside of the body coupling portion 202. The pressurizing protrusion 208 presses the placement step 178 of the pump support 170 downward, so that the pump support 170 and the pump 230 are stably coupled to the body 110.

[0083] The pump coupling part 210 has a hollow cylindrical shape, and its upper and lower ends have an open structure. The pump 230 and the support body 180 are inserted into the pump coupling part 210. In addition, the lower end of the pump coupling part 210 communicates with the inner space of the body coupling part 202.

[0084] A ring-shaped locking projection 214 is formed to protrude inwardly inside the pump coupling portion 210. Additionally, the locking projection 214 has a shoulder air hole 216 that is partially cut. The locking projection 214 presses downward on a flange 233 formed around the outer shell 232 of the pump 230, so that the pump 230 is stably fixed to the pump insertion space 154. Refer to Figure 2 , the flange 233 does not contact the upper end portion of the support body 180 of the pump support member 170, but is spaced apart by a predetermined distance. Through the above-described distance, air outside the container 100 can flow into the inside of the filling space 112 through the shoulder air hole 216, the support air groove 190, and the air nozzle 132.

[0085] The shoulder air hole 216 corresponds to an arc-shaped hole formed by partially cutting a part of the locking projection 214. Additionally, an internal coupling projection 212 protrudes below the shoulder air hole 216.

[0086] A plurality of internal coupling projections 212 are formed on the inner circumferential surface of the pump coupling portion 210 at a predetermined interval. The internal coupling projections 212 are inserted into body locking grooves 182 formed on the outer circumferential surface of the support body 180.

[0087] Figure 14 is a cross-sectional view illustrating the state in which the body cover 150, the pump support member 170, and the shoulder 200 are combined. For reference, Figure 14 the dotted arrow indicates the inflow direction of air.

[0088] Refer to Figures 2 to 3 and Figure 14 , the content in the filling space 112 flows into the body outflow passage 113 through a lower body hole 116 formed below the partition 114 by the suction force of the pump 230, then rises, and is discharged to the outside of the body outflow passage 113 through an upper body hole 126. Additionally, after the content is discharged from the upper body hole 126, it flows into the inside of the inflow passage projection 162, then flows into the pump insertion space 154 through the cover inflow hole 160 and the cover passage 158. Furthermore, after the content flows into the inside of the outer shell 232 from the pump insertion space 154 by the suction force of the pump 230, it is discharged to the outside of the container 100 through a nozzle 222 provided on the nozzle cap 220.

[0089] Thus, since the container 100 of the present embodiment does not have a hose for sucking the content inside the main body 110, the structure is simple, and the problem of the aesthetic decline caused by the hose can be solved.

[0090] As the contents flow out from the inside of the filling space 112 through the pump 230, the pressure inside the filling space 112 may decrease. Due to this decrease in the pressure inside the filling space 112 resulting in a decrease in the suction force of the pump 230, it is necessary to maintain the pressure inside the filling space 112 at a constant pressure (e.g., atmospheric pressure).

[0091] In the container 100 according to the present embodiment, outside air flows into the inside of the pump coupling part 210 through the space (not labeled) formed between the inner circumferential surface of the nozzle cap 220 and the pump coupling part 210. Additionally, the air that has flowed into the pump coupling part 210 flows into the inside of the filling space 112 through the shoulder air hole 216, the support air groove 190, and the air nozzle 132. In this way, by allowing outside air to flow into the inside of the filling space 112 to maintain atmospheric pressure, the suction force of the pump 230 can be maintained at a constant level.

[0092] Although the above has been described with reference to an embodiment of the present invention, those skilled in the art will understand that various modifications and changes can be made to the present invention without departing from the spirit and scope of the present invention described in the following claims.
