Hereinafter, with reference to the accompanying drawings, a metering container having a residual gas discharge function according to a preferred embodiment of the present invention will be described in detail.

1 is a longitudinal sectional view of an injection container according to an embodiment of the present invention.

Referring to FIG. 1, the spray container includes a housing 100 and a nozzle assembly 200.

The housing 100 includes a body 110 having an internal space S configured to accommodate contents and injection gas, and lower and upper sealing caps 120 and 130 for sealing both ends of the body 110, respectively. do. The lower sealing cap 120 may have a curved shape toward the inner space S in order to be deformed to enlarge the volume of the inner space S when a certain level of overpressure is applied to the inner space S. . The support member 140 for supporting the nozzle assembly 200 is coupled to the upper sealing cap 130.

The nozzle assembly 200 is disposed in the support member 140 with one end disposed in the inner space S and the other end exposed to the outside of the housing 100, and the user presses the inner space S. Allow the contents filled in to be sprayed to the outside.

The injection button 250 detachably coupled to the free end of the nozzle assembly 200 is limited in the moving range by the support member 140. The limitation also limits the operating range of the nozzle assembly 200. This is further described below.

2 is a cross-sectional view illustrating a non-operational state of the nozzle assembly 200 of FIG. 1, and FIG. 3 is a conceptual view illustrating the valve stem 220 of FIG. 2.

Referring to FIG. 2, the nozzle assembly 200 includes a nozzle body 210, a valve stem 220, and an injection controller 230.

The nozzle body 210 may be a hollow body disposed in the internal space S of the housing 100. The hollow portion of the nozzle body 210 is a space in which the contents and the like flow, specifically, a space portion 211 in which the contents and the like are introduced from the internal space S and the valve stem 220 is disposed. The gap between the nozzle body 210 and the support member 140 and the valve stem 220 is blocked by the gasket or sealing material 245.

The valve stem 220 is disposed in the space portion 211 so as to be movable along its longitudinal direction. The valve stem 220 is elastically supported by an elastic body 240 supported by a portion of the nozzle body 210, for example, the stepped portion 212, and against or with the help of the elastic force of the elastic body. Receive and move. As the elastic body 240, for example, a coil spring, a leaf spring and the like can be used.

The valve stem 220 is formed with a passage that can communicate with the space 211. The passage is an outflow hole 221 for communicating the hollow portion and the space portion 211 of the valve stem 220 and an outflow for communicating the contents introduced into the hollow portion through the outflow hole 221 to the outside of the housing 100. Furnace 222.

The injection control unit 230 is formed between the nozzle body 210 and the valve stem 220, so that the contents can be injected in an intermittent or continuous manner.

2 and 3 together, the injection control unit 230 is the opening and closing member 231 is formed on the nozzle body 210, the blocking portion 232 and the opening portion 233 formed on the valve stem 220 It includes.

The opening and closing member 231 is formed to protrude from an inner surface defining the space portion 211 of the nozzle body 210. In a state in which the valve stem 220 is not pressed or in a normal state (state of FIG. 2), the opening and closing member 231 maintains a constant distance from the valve stem 220.

In the steady state, the portion of the valve stem 220 corresponding to the opening and closing member 231 is the communication portion 223 having the smallest diameter. By the gap between the opening and closing member 231 and the communication unit 223, the contents of the internal space (S) in the normal state can flow without restriction in the space 211. The opening and closing member 231 is an elastically deformable material and may be, for example, PE.

The blocking portion 232 is a portion of the valve stem 220 having a larger diameter than the communicating portion 223. When the valve stem 220 is pressed to the first depth so that the blocking portion 232 corresponds to the opening / closing member 231, the opening / closing member 231 is deformed by the blocking portion 232 so that they close to each other. . By the close contact, the contents of the internal space S can flow only to a portion corresponding to the opening and closing member 231 in the space 211.

The opening 233 is a portion of the valve stem 220 adjacent to the shutoff 232. The opening portion 233 may have a diameter larger than that of the blocking portion 232. At least one slot 233a may be formed in the opening part 233. The slot 233a may be formed along the longitudinal direction of the valve stem 220, and may be formed to be spaced apart from adjacent slots at regular intervals along the outer circumferential direction of the valve stem 220. The slot 233a has a length extending beyond the length in close contact with the opening and closing member 231, so that both end side regions may be exposed to the outside even when the slot 233a is in close contact with the opening and closing member 231.

Now, the operation of the spray container will be described with reference to FIGS. 2 to 5.

4 is a cross-sectional view of the nozzle assembly 200 in which the valve stem 220 of FIG. 2 is pressed down to a first depth, and FIG. 5 is a nozzle of the valve stem 220 of FIG. 4 pressed down to a second depth. A cross-sectional view of assembly 200.

In the normal state as shown in FIG. 2, the outlet hole 221 of the valve stem 220 is almost located outside the injection container. The outlet hole 221 does not communicate with the space 211 of the nozzle body 210. As a result, due to the open gap between the opening and closing member 231 and the communication portion 223, the contents proceeding from the internal space S to the portion where the elastic body 240 of the space portion 211 is disposed are valve stem ( It will not be sprayed to the outside blocked by 220).

Referring to FIG. 4, as the valve stem 220 is pressed to the first depth, the opening / closing member 231 is in close contact with the blocking portion 232 of the valve stem 220 while being deformed. The outflow hole 221 moved to the space portion 211 of the nozzle body 210 communicates with the space portion 211. As a result, the upper contents of the space portion 211 in which the elastic body 240 is disposed are injected to the outside via the outlet passage 222 of the valve stem 220 through the outlet hole 221.

The injection button 250 is provided in communication with the outflow passage 222, and the movement range of the injection button 250 is limited by the support member 140, so that the valve stem 220 is provided only to the first depth. Will be pressed. Therefore, when the user presses once, only approximately the same amount of contents are intermittently sprayed once in the spray container.

Referring to FIG. 5, for implementing a continuous injection mode, the valve stem 220 is pressed down to a second depth. In order to press the valve stem 220 to the second depth, the aforementioned injection button 250 should be removed from the valve stem 220 so that the valve stem 220 can be pressed beyond the first depth.

In the continuous mode, the opening and closing member 231 corresponds to the opening 233. The opening and closing member 231 is in close contact with the opening part 233, but the upper and lower parts separated based on the opening and closing member 231 of the space part 211 are communicated by the slot 233a.

As a result, the contents of the internal space S move upward from the lower portion of the space portion 211 through the slot 233a, and then flow into the outflow path 222 through the outlet hole 221 and then to the outside. Discharged continuously.

According to this configuration, there is an advantage that the continuous injection can be made in the case of discharging the remaining contents (gas) while implementing the metering mode for the contents of the injection container.

In addition, a complicated process for switching between the metered injection and the continuous injection mode is not necessary, and the user can simply switch the valve stem 220 more deeply.

In addition, the above mode switching may be structurally distinguished simply by pressing and without mounting the injection button 250.

Next, an embodiment in which the valve stem 220 can be easily pressed to the second depth during the continuous injection will be described with reference to FIGS. 6 and 7.

FIG. 6 is a cross-sectional view illustrating a state in which the injection cap 260 coupled to the housing 100 presses the valve stem 220 to a second depth, and FIG. 7 is an enlarged cross-sectional view of portion A of FIG. 6.

Referring to FIG. 6, the injection container according to another embodiment of the present invention may further include an injection cap 260 coupled to one side of the housing 100 to surround the nozzle assembly 200.

The injection cap 260 is detachably coupled to the housing 100 as the coupling portion 265 is coupled to the edge of the upper sealing cap 130. A recess 262 is formed at the closed end of the injection cap 260. In the center of the portion where the recess 262 is formed, a pressurizing portion 261 capable of pressing the valve stem 220 is formed. Naturally, in order for the pressurization part 261 to pressurize the valve stem 220, the injection button 250 should be removed from the valve stem 220.

The pressurization portion 261 is formed with outlets 261a and 261b communicating with the outflow path 222 of the valve stem 220, so that the valve stem 220 is pressed to the second depth by the pressurization portion 261. In this case, the contents continuously injected from the outflow passage 222 are guided to the outside.

In order to ensure that the valve stem 220 is pressed to the second depth, an engagement portion 263 may be further formed on the end side of the injection cap 260. When the coupling portion 263 is fitted to the end of the support member 140 and coupled, the valve stem 220 is pressed by the pressing portion 261 and automatically pressed to the second depth by the coupling. .

According to this configuration, the injection cap 260 may be used to implement the continuous injection mode, so there is no need to find another tool.

In addition, since the valve stem 220 is pressed to the second depth only by the coupling of the injection cap 260 and the support member 140 by the coupling part 263, the user may arbitrarily select the degree to which the valve stem 220 is pressed. There is an advantage of not having to adjust.
