Description

Technical Field

[0001] The present invention relates to a container for spraying liquid, which has an improved channel structure for discharging the content. Background Art

[0002] In cosmetic containers, etc., a pump is coupled to the upper inlet of a container storing liquid contents such as perfume, so as to discharge and spray a fixed amount of the contents to the outside. When a user presses down a nozzle corresponding to a button to spray the liquid contents, the contents flowing into the pump are pressurized and rise along the discharge channel and are sprayed through the nozzle. Then, when the nozzle is released from pressure, the discharge channel is mechanically closed due to the rise of the nozzle, and as the pressure inside the pump decreases, the contents flow from the container to replenish it.

[0003] This pump is used for spraying various contents, such as perfumes and cosmetics, as well as fragrances, insecticides, etc. In particular, since a fixed amount of contents can be discharged by one nozzle pressurization, and the contents are not exposed to the outside, it is convenient to use, and therefore the demand for it is increasing. Korean Patent No. 1963619 discloses the general structure of a conventional pump and a container combined with a pump.

[0004] On the other hand, the pump is connected to a long hose to discharge the contents from the body storing the contents, and the lower end of the hose is connected to the bottom surface of the body. The suction force of the pump is transmitted to the hose, so that the contents stored in the body flow into the pump through the hose. This hose allows the contents stored in the body to be used in full, but since it is inserted into the interior of the body and visible from the outside, it becomes a factor that reduces the aesthetics of the body. In particular, when the body corresponds to a cosmetic container, the problem of reduced aesthetics is more prominent. Therefore, in most cases, the container using the pump is made of an opaque material to prevent the hose from being exposed to the outside. Summary of the invention

[0005] Technical issues

[0006] Therefore, the present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a container for spraying liquids which can eliminate a hose by improving a channel structure for discharging the contents.

[0030] The terms used in this application are only used to illustrate specific embodiments and are not intended to limit the present invention. Unless clearly defined differently in the context, singular expressions include plural expressions. In this application, terms such as "including" or "having" should be understood as being used to specify the presence of features, numbers, steps, actions, constituent elements, parts or combinations thereof recorded in the specification, rather than excluding in advance the presence or additivity of one or more other features or numbers, steps, actions, constituent elements, parts or combinations thereof.

[0031] The terms "first", "second", etc. can be used to describe various components, but these components should not be limited to these terms. These terms are only used to distinguish one component from other components.

[0032] 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 figure numbers regardless of the figure numbers, and repeated descriptions thereof are omitted.

[0033] The container for spraying liquid of this embodiment can spray various liquids such as cosmetics, perfume, shampoo, various lotions, disinfectants, medicines, etc., and is not limited by the type and nature of the contents that become the spraying object.

[0034] Figure 1 1 is a perspective view of a container 100 for spraying liquid according to a first embodiment of the present invention. Figure 2 is a central longitudinal sectional view of the container 100, Figure 3 Is magnification Figure 2 For reference, Figure 3 The arrows shown indicate the discharge flow direction of the contents.

[0035] Reference Figures 1 to 3 The container 100 of this embodiment is characterized in that the hose in the filling space 112 of the body 110 for storing the contents (not shown) is removed, and a channel for discharging the contents is formed on one side of the body 110 by a partition 114 or the like. Therefore, the structure of the container 100 of this embodiment can be simplified, and even if the material of the body 110 is made transparent, the hose inside it is invisible, thereby further improving the aesthetics of the container.

[0036] The container 100 of the present embodiment includes a body 110 , a body cover 150 , a pump support 170 , a shoulder 200 , a nozzle cap 220 , a pump 230 , and an upper cap 250 .

[0037] The upper cap 250 has a hollow quadrangular prism shape with an open lower portion, and is coupled to the periphery of the shoulder 200 to cover the nozzle cap 220 .

[0038] The nozzle cap 220 is inserted into the shoulder 200, and the nozzle 222 provided therein is inserted into and coupled to the valve 234 of the pump 230. 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 contents passing through the valve 234 of the pump 230 can be discharged to the outside of the container 100 through the nozzle 222.

[0039] The lower portion of the pump 230 is inserted into the pump insertion space 154 formed on the body cover 150, and the housing 232 is pressed downward 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 sucks the inflowing content into the inside thereof, so that the content can be discharged through the nozzle 222.

[0040] Figures 4 to 6 yes Figure 1 The illustrated main body 110 of the container 100 is a perspective view, a perspective cross-sectional view (longitudinal cross-sectional view), and a transverse cross-sectional view.

[0041] Although the container 100 of this embodiment is illustrated as having a quadrilateral body 110, the present invention is not limited to the cross-sectional shape of the body 110. Therefore, in another embodiment of the container of the present invention, the body may have a polygonal shape such as a circle, an ellipse, a triangle or a pentagon.

[0042] refer to Figures 3 to 6 The body 110 has a filling space 112 for storing the contents, and the filling space 112 is separated from the body outflow channel 113 by a partition 114. The partition 114 is formed along the length direction of the body 110, and can be formed adjacent to at least one side surface of the four internal surfaces of the body 110. A gap (no reference numeral) is formed between the lower end of the partition 114 and the base 134, and the contents of the filling space 112 can flow into the body outflow channel 113 through the gap.

[0043] A hole (not shown) may be formed at a lower end portion of the partition plate 114 to communicate the filling space 112 with the body outflow channel 113 .

[0044] The partition 114 may be formed to have a width sufficient to cover any one of the four surfaces of the body 110. In order to prevent the partition 114 from being easily observed from the outside, the partition 114 and the body 110 may be made of the same material and color.

[0045] The body outflow channel 113 has a smaller cross-sectional area than the filling space 112, and corresponds to a channel for the contents to move upward. That is, through the operation of the pump 230, the contents flow into the body outflow channel 113 through the lower portion of the partition 114 and rise, and flow into the pump insertion space 154 through the upper body hole 126 and the cover channel 158. In this way, the body outflow channel 113 is provided on one side of the body 110 to provide a channel for the contents to move.

[0046] The weight 140 may be inserted into the body outflow channel 113. The weight 140 may have a cross section that is the same as but slightly reduced in cross section shape as the body outflow channel 113. By inserting the weight 140 into the body outflow channel 113, a fine channel for the movement of the contents may be formed.

[0047] Of course, when the cross-sectional area of ​​the main body outflow channel 113 is sufficiently small, the counterweight 140 may not be inserted.

[0048] A coupling surface 118 may be formed at the upper portion of the body 110, and the lower portion of the body 110 may have an open structure. In addition, 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 body protrusion 125 are formed on one side thereof. The coupling surface 118 is formed slightly apart from the upper end portion of the body 110, so that the upper portion of the body 110 has a concave shape through the coupling surface 118, and the body cover 150, the pump support 170, and the shoulder 200 are sequentially inserted therein.

[0049] 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, a pump insertion space 154 for inserting the body cover 150 is inserted inside the center protrusion 122. The contents are not discharged through the center hole 120, and the center hole 120 allows the body cover 150 to be fixed in position and coupled to the body 110.

[0050] The body protrusion 125 has a hollow cylindrical shape with an open upper portion and a lower portion partially closed by the coupling surface 118. In addition, an upper body hole 126 is formed on the coupling surface 118 located inside the body protrusion 125. In addition, a channel protrusion 162 formed below the body cover 150 is inserted into the interior of the body protrusion 125 and communicates with it. In this way, the body protrusion 125 has a certain internal space corresponding to the portion that connects the upper body hole 126 and the cover channel 158 corresponding to the channel for the outflow of the contents to each other to constantly limit the volume of the outflow channel and form a closed outflow channel.

[0051] A coupling groove 130 may be formed at a corner portion of the upper inner circumference of the body 110. A coupling protrusion 206 formed at the outer circumference of the shoulder 200 is inserted into the coupling groove 130, so that the shoulder 200 is coupled to the upper portion of the body 110.

[0052] The air nozzle 132 has a hollow cylindrical shape, and its lower end is connected to the filling space 112. External air can flow into the filling space 112 through the air nozzle 132, so that the pressure of the filling space 112 can be prevented from decreasing and maintained at atmospheric pressure. In addition, the air nozzle 132 is inserted into the air inflow hole 167 formed on the body cover 150, and its upper end is open.

[0053] Figure 7 It is a perspective view illustrating the base 134 and the weight 140 .

[0054] refer to Figure 2 and Figure 7 , the base 134 may be coupled to the open lower portion of the body 110. The base 134 may correspond to a plate having the same cross section as the body 110 and formed thinner. The base 134 may be fixedly coupled to the lower portion of the body 110 by bonding or welding. In addition, the lower end portion of the weight 140 may be coupled to the upper surface of the coupled base 134.

[0055] The counterweight 140 has a cross section of the same shape and slightly smaller size as the body outflow channel 113. Therefore, the counterweight 140 can reduce the cross section of the body outflow channel 113 so that the contents can quickly pass through the body outflow channel 113. In addition, the counterweight 140 can be integrally made with the base 134 and combined with the body 110.

[0056] Figure 8 and Fig. 9 1 and 1 are perspective views and cross-sectional views illustrating the main body cover 150 .

[0057] refer to Figures 2 to 3 as well as Figures 8 to 9 The body cover 150 is coupled to the upper portion of the body 110, and the pump support 170 and the shoulder 200 are coupled to the upper portion thereof in sequence. The body cover 150 has a cover surface 152 having the same shape as the cross section of the 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 portion. In addition, a pump insertion space 154, a cover passage 158, and an air inlet hole 167 are provided inside the upper circumferential surface 164. In addition, a passage protrusion 162 protrudes downward below the cover surface 152.

[0058] The pump insertion space 154 is a groove formed concavely 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 pump insertion space 154. In addition, a hole (no reference numeral) is formed on the bottom 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 bottom surface of the housing 232.

[0059] The pump insertion space 154 protrudes downward from the cover surface 152 , and the pump insertion space 154 is inserted into the central protrusion 122 of the body 110 .

[0060] The upper side of the pump insertion space 154 is communicated with the cover passage 158. Therefore, the content flowing in through the cover passage 158 drops to the bottom surface of the pump insertion space 154 and flows into the interior of the housing 232.

[0061] A cover passage 158 having a prescribed width and depth is horizontally formed on the cover surface 152. The cover passage 158 may have a quadrilateral cross section, one end of which is communicated with the cover inflow hole 160, and the other end of which is communicated 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 portion is closed by a pump support 170.

[0062] The cover inlet hole 160 formed at one end of the cover passage 158 is formed through the cover surface 152 and communicates with the internal space of the passage protrusion 162 .

[0063] The channel protrusion 162 is formed by protruding from the bottom of the cover surface 152, has a hollow cylindrical shape, and has an open structure at the lower end. In addition, the upper end of the channel protrusion 162 is closed by the cover surface 152, and is connected to the cover channel 158 only through the cover inlet 160. The channel protrusion 162 is inserted into the body protrusion 125 formed on the upper part of the body 110.

[0064] A coupling protrusion 166 is formed on the outer circumference of the upper circumferential surface 164. When the pump support 170 is coupled to the upper portion of the body cover 150, the upper circumferential surface 164 is inserted into a coupling groove 176 formed between the outer circumferential surface 172 and the inner circumferential surface 174 thereof, and at this time, the coupling protrusion 166 can be inserted into a groove (without a reference numeral) formed on the inner circumferential surface of the outer circumferential surface 172.

[0065] An air inflow hole 167 having a hollow cylindrical shape is formed inside the upper circumferential surface 164. The air nozzle 132 of the body 110 is inserted into the air inflow hole 167. Through the open upper end of the air nozzle 132, air can flow into the filling space 112 of the body 110.

[0066] Fig.10 and Fig.11 1 and 2 are a perspective view and a perspective sectional view illustrating the pump support 170 .

[0067] refer to Figures 2 to 3 as well as Figure 10 to Figure 11 The pump support 170 is coupled to the upper portion of the body cover 150 to stably support the pump 230 and prevent external air from flowing into the pump insertion space 154. The pump support 170 includes a support body 180 having a hollow cylindrical shape located in the center, and an outer circumferential surface 172 and an inner circumferential surface 174 formed around it.

[0068] The outer circumferential surface 172 and the inner circumferential surface 174 have a quadrilateral cross section, and a coupling groove 176 corresponding to the spacing is formed therebetween. The upper circumferential surface 164 of the body cover 150 is inserted into the coupling groove 176 by means of an interference fit (press fitting). In addition, a placement boss 178 is formed on the upper portion of the outer circumferential surface 172, and the upper surface thereof is pressed downward by a press protrusion 208 provided inside the shoulder 200.

[0069] The support body 180 is located inside the inner circumferential surface 174 and has a height greater than the inner circumferential surface 174. A body retaining groove 182 is formed on the outer circumferential surface of the support body 180, and an internal coupling protrusion 212 formed inside the shoulder 200 is inserted into the body retaining groove 182. Through such a body retaining groove 182 and the internal coupling protrusion 212, the shoulder 200 is stably coupled to the pump support 170.

[0070] The housing 232 of the pump 230 is inserted into the empty space inside the support body 180. In addition, a ring-shaped tightening protrusion 192 is formed on the lower inner peripheral surface of the support body 180. The tightening protrusion 192 presses and tightens the outer peripheral surface of the housing 232 of the pump 230, thereby preventing external air from flowing into the pump insertion space 154.

[0071] The inner circumference of the support body 180 is formed with a support air groove 190 starting from the upper end and having a predetermined length. A predetermined gap is formed between the support air groove 190 and the housing 232 of the pump 230, and air flows into the upper end of the air nozzle 132 of the body 110 through the gap.

[0072] An annular empty space is formed between the inner circumferential surface 174 and the support body 180, in which a support insertion groove 186 having an upper surface 187 is formed. The support insertion groove 186 corresponds to an empty space whose upper portion is closed by the upper surface 187 and whose lower portion is open.

[0073] The air nozzle 132 formed on the body 110 is inserted into the support insertion groove 186. In addition, since the upper end of the air nozzle 132 is not connected to the upper surface 187, a passage through which air can move is formed therebetween.

[0074] An annular packing member 260 may be provided at the end of the support body 180 of the pump support member 170 . The packing member 260 is inserted around the outer shell 232 of the pump 230 and is located at the lower part of the flange 233 .

[0075] Fig.12 and Fig.13 1 and 2 are a perspective view and a perspective cross-sectional view illustrating the shoulder 200 .

[0076] refer to Figures 2 to 3 as well as Figure 12 to Figure 13 The shoulder 200 is combined with the upper part of the pump support 170 to pressurize the pump 230 downward, and the nozzle cap 220 is combined with the upper part thereof. The shoulder 200 is composed of a pump coupling part 210 in a hollow cylindrical shape and a body coupling part 202 formed around it and only opened at the lower part.

[0077] The body joint part 202 has a joint circumferential surface 204 which is inserted into the groove formed by the joint surface 118 at the upper part of the body 110 as described above. In addition, since the lower part of the body joint part 202 is open, the body cover 150 and the pump support 170 are accommodated therein.

[0078] 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, a pump coupling portion 210 is protrudingly formed at the center of the upper surface. In addition, a pressurizing protrusion 208 is protruding downwardly formed on the upper surface from the inside of the body coupling portion 202. The pressurizing protrusion 208 presses the placement boss 178 of the pump support 170 downwardly, so that the pump support 170 and the pump 230 are stably coupled to the body 110.

[0079] 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.

[0080] An annular locking protrusion 214 is formed inwardly protruding inside the pump coupling portion 210. In addition, the locking protrusion 214 has a partially cut shoulder air hole 216. The locking protrusion 214 presses downward the 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. Figure 2 and Figure 3 The flange 233 is not in contact with the upper end of the support body 180 of the pump support 170, but is separated by a predetermined distance. With the above-mentioned distance, the air outside the container 100 can flow into the filling space 112 through the shoulder air hole 216, the support air groove 190 and the air nozzle 132.

[0081] The shoulder air hole 2166 corresponds to an arc-shaped hole formed by opening a part of the locking protrusion 214. In addition, the inner coupling protrusion 212 is protrudingly formed at the lower part of the shoulder air hole 216.

[0082] A plurality of inner coupling protrusions 212 are formed at predetermined intervals on the inner peripheral surface of the pump coupling portion 210 . The inner coupling protrusions 212 are inserted into the body locking grooves 182 formed on the outer peripheral surface of the support body 180 .

[0083] Fig.14 is a cross-sectional view of the pump 230 .

[0084] refer to Fig.14 The pump 230 includes a housing 232, a valve 234, a housing cap 236, a piston 238, a guide member 240 and a disc 242. Since the pump structure is the same or similar to the pump structure described in Korean Patent No. 1963619, it will not be described in detail.

[0085] refer to Figures 2 to 3 , by the suction force of the pump 230, the content in the filling space 112 flows into the body outflow channel 113 through the channel formed at the lower part of the partition 114, rises and is discharged to the outside of the body outflow channel 113 through the upper body hole 126. In addition, after the content is discharged from the upper body hole 126 and flows into the inside of the channel protrusion 162, it flows into the inside of the pump insertion space 154 through the cover inflow hole 160 and the cover channel 158. In addition, after the content flows into the inside of the housing 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 the nozzle 222 provided on the nozzle cap 220.

[0086] As such, since the container 100 of this embodiment does not have a hose for sucking the contents inside the body 110 , the structure is simple and the problem of reduced aesthetics due to the hose can be solved.

[0087] As the contents flow out of the filling space 112 through the pump 230, the pressure inside the filling space 112 may drop. Such a drop in the pressure inside the filling space 112 may cause a drop in the suction force of the pump 230, so it is necessary to maintain the pressure inside the filling space 112 at a constant pressure (e.g., atmospheric pressure).

[0088] In the container 100 of the present embodiment, external air flows into the interior of the pump coupling portion 210 through a gap (no reference numeral) formed between the nozzle cap 220 and the inner circumferential surface of the pump coupling portion 210. In addition, the air flowing into the pump coupling portion 210 flows into the interior 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 external air to flow into the interior of the filling space 112 to maintain the atmospheric pressure, the suction force of the pump 230 can be maintained at a constant level.

[0089] Although the present invention has been described above with reference to an embodiment, it will be appreciated by those skilled in the art that various modifications and variations may be made to the present invention without departing from the spirit and scope of the invention as described in the following claims.
