2. Description of the Related Art A shampoo, a hand soap, a facial cleanser, a hairdressing agent, a shaving agent and the like are contained in a liquid, and a pump mechanism having a nozzle body, a cylinder body and a piston body as main components is integrally formed in a container. As for the installed pump-type discharge container, those having various pump structures have been conventionally proposed and commercialized, and in such a pump-type discharge container, a nozzle body protruding upward from a cap of the container is pushed down (and Release), a piston body in the container body connected to the nozzle body via a cylindrical stem portion penetrating the top plate portion of the cap is vertically suspended from the mouth of the container body into the container. The liquid stored in the container body is sucked up from the lower end of the cylinder body by moving the cylinder body up and down while being constantly biased upward by the spring force. The through hollow axis portion, as is, or after the foam state by aerating,
The liquid is discharged from the discharge port of the nozzle body to the outside of the container.

As such a pump-type discharge container, for example, a large-diameter air piston and a small-diameter liquid piston are formed by using a double cylinder in which a large-diameter air cylinder and a small-diameter liquid cylinder are integrated as a cylinder body. The pump body has a pump structure in which a piston body integrated with a cylinder body is vertically movably arranged while being constantly urged upward by a spring force with respect to a cylinder body, and each screw provided on a nozzle body and a cap, respectively.

[0005]

By the way, pump-type discharge containers containing liquids such as shampoos and facial cleansers are often used in places such as bathrooms and shower rooms. In many cases, hot water or water splattering or splashing on the floor adheres to each part of the container in use, whereas the above-described conventionally known pump-type discharge container has the following problems. Regardless of the pressure, the nozzle body is pushed down (and the pushing down is released)
When the lock state of the nozzle body with respect to the cap is released for operation and the piston body and the nozzle body are lifted by the upward biasing force of the spring, the cylindrical body that integrally connects the nozzle body and the piston body Is exposed outside above the top plate of the cap.

That is, for example, as shown in FIG. 7, when the nozzle body 4 and the screw cylinders 34 and 44 of the cap 3 are screwed together and the nozzle body 4 is locked with respect to the cap 3, The gap between the outer surface of the stem portion (41, 71) connecting the piston body 6 and the piston body 6 and the inner surface of the threaded tube portion 34 of the cap 3 and the screwed tube portion 34 , 44, when the nozzle body 4 is unlocked and the nozzle body 4 is raised, as shown in FIG. 8, the stem portion (41, 41) above the top plate portion of the cap 3. 71) and the screw cylinder 34 are exposed to the outside.

[0007] In such a state of use of the container, if water scattered adheres to the surface of the container, the water adhered to the cylindrical stem portion flows down and can enter the gap between the stem portion and the cap top plate portion. In addition, this gap is used to introduce air from outside to prevent the inside of the container from becoming negative pressure due to the discharge of the contents, and to release the air necessary to foam the contents liquid to the outside. Since it is an air suction port for introducing air from the space, water entering the gap easily enters the container together with the air.

As a result, the water that has infiltrated into the container will usually wash away the lubricant such as silicon applied to the cylinder portion, thereby deteriorating the sliding property of the piston body, or the liquid contained in the container body. And may cause a problem such as changing the color or scent of the mixture.

Particularly, in the case of a foaming container in which air is mixed with the content liquid and discharged in a foam state, if a considerable amount of water is accumulated in the air chamber defined by the cylinder body and the piston body, the mixing chamber becomes Since the ratio of the content liquid and the air to be sent is different from the start of use, there is a problem that the foam quality differs from the designed one, or the water entering the container is dirty. In many cases, mold and the like easily accumulate in the air cylinder and cause mold and the like, and in that case, the mold smell is sent into the mixing chamber by pumping, which deteriorates the aroma of the discharged foam. Problems can also arise.

Regarding the gap between the cylindrical stem portion and the cap top plate portion, Japanese Patent Laid-Open Publication No. 7-867 discloses that the nozzle body is locked to the cap at its lower limit position according to FIGS. Each screw cylinder portion (screw tube) is formed to be considerably longer than the screw forming portion, and even if the nozzle body is at the upper limit position, portions other than the screw forming portion of each screw tube portion are brought into sliding contact with each other. According to such a configuration, even when the locked state of the nozzle body and the cap of the container is released and the nozzle body is raised, the stem portion is exposed to the outside by both screw cylinder portions. Not to be.

However, even with such a structure, the water adhering to the outer surface of each of the screw cylinders causes a slight gap between the two screw cylinders due to the sliding of each of the screw cylinders by the operation of pushing down the nozzle body. (The external air is introduced into the container through this gap) by capillary action, and the water that has entered the gap between the two screw cylinders together with the air sucked into the container from the gaps causes the water in each screw cylinder to move. The water that invades and accumulates inside and accumulates inside each screw cylinder, without being excluded to the outside, passes through the gap between the stem portion and the cap top plate, and is introduced into the container. At the same time, they enter the container.

In addition, each screw tube portion is formed to be considerably longer than its screw forming portion so that both screw tube portions (screw tubes) overlap in the vertical direction even at the upper limit position of the nozzle body. When the nozzle body is locked with respect to the cap by each screw cylinder at the lower limit position of the nozzle body, the nozzle body protrudes greatly above the cap by the length of the screw cylinder, and the entire container is It becomes high and bulky.

An object of the present invention is to solve the above-mentioned problems. Specifically, for a pump-type discharge container, a cylindrical stem portion extending downward from a nozzle body at the time of use thereof and a top of a cap are provided. In addition to preventing water from entering the container from the gap with the plate portion, the nozzle body is fixed to the cap at its lower limit position and the upward protrusion of the nozzle body when the nozzle body is locked is kept as low as possible. That is the task.

[0014]

According to the present invention, in order to solve the above-mentioned problems, a cylinder body is vertically provided from a mouth portion of a container body having a cap mounted thereon toward the inside of the container body,
A piston body is provided so as to be able to move up and down while being constantly urged upward by a spring force with respect to the cylinder body, and the piston body is provided via a cylindrical stem portion penetrating through the center of the top plate portion of the cap. And a screw tube portion integrally connected to the nozzle body located outside the container body and for fixing and locking the nozzle body to the cap at its lower limit position is concentric with the cylindrical stem portion. In the pump-type discharge container formed on the top plate portion and the nozzle body of the cap, the lower cover tube portion having a diameter larger than that of each screw tube portion is concentric with the cylindrical stem portion. An upper cover cylinder having a diameter larger than that of the lower cover cylinder is formed vertically from the nozzle body, and is formed on the top plate of the cap so as to face the lower end of the upper cover cylinder. Form a recess, the upper limit of the nozzle body In this state, the upper ends of the lower cover cylinders and the lower ends of the upper cover cylinders that are spaced apart in the radial direction slightly overlap each other in the height direction, and the screw cylinders of the nozzle body and the cap are screwed together. In addition, when the nozzle body is at the lower limit position, the lower end of the upper cover cylinder of the nozzle body is configured to enter into the annular recess of the top plate of the cap.

According to the above configuration, even when the locked state with the cap is released and the nozzle body is at the upper limit position, the upper cover cylindrical portion formed on the top plate portion and the nozzle body formed on the nozzle body, respectively. The lower cover tube portion shields the tubular stem portion from hot or cold water that has splattered or bounced off, so that water does not adhere to the outer surface of the tubular stem portion, and the upper cover tube portion And water adhering to the outer surface of the lower cover tube does not flow down along the outer surface of each cover tube and enter the inside of the screw tube, so that the stem and cap top plate No water enters the gap.

In a state in which the screw body of the cap and the nozzle body are screwed together and the nozzle body is locked at the lower limit position, the lower end of the upper cover cylinder part of the nozzle body is located in the annular recess of the cap top plate. With this configuration, the upward protrusion of the nozzle body from the cap in the locked state can be suppressed to be lower by an amount corresponding to the upper cover cylindrical portion having entered the concave portion of the cap.

a and 18b are not limited to nets having meshes,
Any porous sheet having a large number of small holes through which bubbles can pass may be used, but in any case, the downstream side 18b farther from the mixing chamber C than the mesh (small holes) on the upstream side 18a close to the mixing chamber C. It is better to make the mesh (small holes) finer (smaller).

The cylindrical stem portion (41, 41,
The nozzle body 4 which is connected to the piston body 6 through the nozzle body 71) has a threaded cylindrical portion 44 having a threaded portion formed on the lower inner peripheral surface concentrically with the stem portion 41 thereof. A threaded tube portion 34 having a threaded portion on the outer peripheral surface is formed upright on the over member 32 of the cap 3 which penetrates the cylindrical stem portion (41, 71) opposite to the threaded tube portion 44 of the body 4. Have been. In addition, the screw cylinder part 34 of the cap 3
Of the stem portion (41, 71) serves as a sliding contact guide portion for guiding the vertical movement of the stem portion (41, 71).
A plurality of shallow vertical grooves are formed on the inner peripheral surface of the screw cylinder portion 34 so as to form a gap through which air can pass between the outer peripheral surface of (1, 71).

The screw tube portion 44 of the nozzle body 4 and the screw tube portion 34 of the cap 3 form the two screw tube portions 34 and 4.
By pressing down the nozzle body 4 until the ends of the threaded portions of the nozzles 4 come into contact with each other, the nozzle body 4 is rotated with respect to the cap 3, and the two screw cylinders 34 and 44 are screwed together.
The nozzle body 4 is fixed to the cap 3 at its lower limit position, and its upward movement is locked.

The operating state of the pump-type foam discharge container 1 of the present embodiment configured as described above will be described below. The consumer starts using the pump-type foam discharge container 1 from the time when the assembly is completed. Immediately before, as shown in FIG. 1, the nozzle body 4 (and the piston body 6) is pushed down against the urging force of the coil spring 14, and the screw barrel 44 of the nozzle body 4 and the screw barrel 34 of the cap 3 are pressed. Is screwed, the nozzle body 4 is locked to the cap 3 with the nozzle body 4 lowered to its lower limit position.

In such a locked state of the nozzle body 4, the air hole E formed in the upper part of the cylinder wall of the air cylinder 52 has an upper end portion 73a and a lower end which are in close contact with the inner surfaces of the upper and lower cylinder walls. The part 73b is closed by the piston part 73 of the integrally formed air piston 7, and the liquid chamber B is completely sealed by the plug member 11 at the lower part of the liquid piston 9 below. In the second check valve at the upper end of the liquid chamber B, the ball valve 16 is brought into close contact with the valve seat 81 by the urging force of the coil spring 17 and the upper end outlet of the liquid chamber B is closed.

In the third check valve at the upper end of the air chamber A,
The outer peripheral portion of the upper surface side of the outer valve portion 20b of the elastic valve body 20 contacts the lower surface of the intermediate connecting portion 72 outside the intake hole F, so that the intake hole F is closed and the inner side of the elastic valve body 20 is closed. Valve part 2
The inner edge of the lower surface side of Oc contacts the upper surface of the annular projection 82 formed on the outer peripheral surface of the liquid piston 8, so that the inlet of the air passage D is closed.

The state in which the air hole E is closed, the lower part of the liquid chamber B is sealed, the upper end outlet of the liquid chamber B is closed, the intake hole F is closed, and the inlet of the air passage D is closed. ,
The nozzle body 4 is securely retained by being locked upwardly with respect to the cap 3, so that the container can be kept for a long time, such as during transportation, from the time when the assembly is completed to immediately before the consumer starts using the same. The liquid stored in the container body 2 may enter the air chamber A through the air hole E,
Does not penetrate into the mixing chamber C or leak out of the container.

Note that, even after the start of use, if the consumer locks the nozzle body 4 when not in use, the liquid stored in the container main body 2 can be filled with the air holes E even if the container is placed on its side. Does not penetrate into the air chamber A or leak out of the container through the
And if the foam remaining in the foam passage G is discharged,
The discharge port 42 of the nozzle body 4 from the liquid chamber B via the mixing chamber C
No leaks leading to

In such a state, before the consumer starts using the screw, the screwing of the screw cylinder 44 of the nozzle body 4 and the screw cylinder 34 of the cap 3 is released, and the lower limit of the nozzle body 4 is lowered. When the locked state at the position is released, the nozzle body 4 and the piston body 6 rise by the urging force of the coil spring 14 and rise to the upper limit position as shown in FIG.

In the upward stroke of the nozzle body 4, in the liquid chamber B, the upper end outlet of the liquid chamber B is closed by the second check valve (the ball valve 16 and the valve seat portion 81) at the upper end. With the connecting rod 8 and the liquid piston 9 rising, the sealing by the plug member 11 is released, and the lower end of the liquid chamber B is responded to the negative pressure in the liquid chamber B due to the rise of the liquid piston 9. The first check valve (the ball valve 12 and the valve seat portion 56) is opened, and the liquid stored in the container body 2 is discharged from the liquid suction pipe 1
3 and is introduced into the liquid chamber B.

In the third check valve at the upper end of the air chamber A,
As the pressure in the air chamber A becomes negative due to the rise of the air piston 7, the lower inner edge of the inner valve portion 20 c of the elastic valve body 20 comes into contact with the upper surface of the annular projection 82 of the connecting rod 8. As a result, while the inlet of the air passage D remains closed, the upper outer edge of the outer valve portion 20b of the elastic valve body 20 separates from the lower surface of the intermediate connecting portion 72, and the intake hole F is opened. ,
External air passes through a gap between the screw cylinder portion 34 of the cap 3 and the stem portion (41, 71) and passes through the intake hole F to the air chamber A.
Introduced within.

When the nozzle body 4 stops at the upper limit position, the second check valve (the ball valve 16 and the valve seat portion 81) at the upper end of the liquid chamber B is closed as shown in FIG. However, when the liquid is introduced into the liquid chamber B and the negative pressure in the liquid chamber B is released, the first check valve (the ball valve 12 and the valve seat 56) at the lower end of the liquid chamber B becomes a ball. In the air chamber A in which the valve 12 is closed by its own weight and the air is sucked and the negative pressure is eliminated, the lower end of the piston portion 73 has an air hole E.
In close contact with the inner surface of the air cylinder 52 below
The upper end portion of the piston portion 73 is the over member 3 of the cap.
The air hole E is closed by close contact with the inner cylindrical portion 32b of the second 2, and the intake hole F and the air passage D are both closed by the elastic valve body 20.

Therefore, when the container in the state shown in FIG. 5 is overturned, the liquid in the container comes into contact with the air hole E, or the liquid foams due to vibration or the like when the liquid is carried, and the air hole E Liquid or bubbles do not enter the air chamber A through the air holes E.

When the nozzle body 4 (and the piston body 6) is pushed down from the upper limit position of the nozzle body 4 against the urging force of the coil spring 14, as shown in FIG. The nozzle body 4 is pushed down to a position before the screw cylinders 34 and 44 are screwed together, and the ends of the screw cylinders 44 of the nozzle body 4 and the screw cylinders 34 of the cap 3 contact each other. The contact prevents the nozzle body 4 from being pushed down at that position.

In the stroke of such a downward stroke of the nozzle body 4, in the liquid chamber B, the first check valve (the ball valve 12 and the valve seat portion 81) at the lower end of the liquid chamber B is closed. The liquid chamber B is moved by the lowering of the rod 8 and the liquid piston 9.
When the inside is pressurized, the second check valve (the ball valve 16 and the valve seat portion 81) at the upper end outlet is opened against the spring force of the coil spring 17, and the liquid chamber B into which the liquid is introduced. Some of the liquid inside is discharged into the mixing chamber C above it.

Further, in the air chamber A, the air chamber A is pressurized by the lowering of the air piston 7 and the third
The check valve is configured such that the elastic valve body 20 receives a pressing force to the intermediate connecting portion 72 side by the air pressure, and the outer valve portion 20b is located on the upper surface side of the cylindrical base portion 20a fixed to the intermediate connecting portion 72. The inner edge portion is more strongly contacted with the lower surface of the intermediate connecting portion 72, and the inner valve portion 20c is bent upward and the lower edge side inner edge portion is separated from the upper surface of the annular projection 82 of the liquid piston 8, so that the intake hole F
Maintains a closed state, the entrance of the air passage D is opened,
The air in the air chamber A is sent into the mixing chamber C above the air chamber D through the air passage D.

As a result, the liquid and air are mixed and foamed in the mixing chamber C, and thereafter, the downstream nets 18a, 18a
By passing through 8b, bubbles of uniform size are obtained. At first, since the liquid chamber B is not completely filled with the liquid and the air is stored in the upper part, when the consumer starts to use and presses down the nozzle body 4 for the first time,
Even if the nozzle body 4 (and the piston body 6) is pushed down to the lower end position of the pushing-down operation as shown in FIG.
Only a small amount of bubbles are discharged from the discharge port 42 together with air.

However, thereafter, by similarly depressing the nozzle body 4, the piston body 6 and each check valve (first to third check valves) operate in the same manner as described above, and the nozzle When the piston body 6 is lowered by pushing down the body 4, air is sent from the air chamber A into the mixing chamber C through the air passage D, while the liquid chamber B is sucked up from the liquid suction pipe 13 to be sucked up from the liquid chamber B. Since the liquid introduced into the mixing chamber C is sent into the mixing chamber C, the air and the liquid sent from the air chamber A and the liquid chamber B are mixed and foamed at a fixed ratio in the mixing chamber C, and the mixing chamber C is foamed. The bubbles discharged from the nozzles pass through the nets 18a and 18b of the net holder 18 disposed in the bubble passage G of the nozzle body 4 in order from the coarser one 18a to the finer one 18b, so that the bubbles are fine and uniform. After being foamed, bubbles in a certain state The discharge port 4 of the fixed amount by the nozzle body 4
2 is discharged.

When the operation of pushing down the nozzle body 4 is released, the piston body 6 and each check valve (first to third check valves) operate in the same manner as at the time of canceling the above-described operation of pushing down, and the liquid is discharged. In the chamber B, the liquid in the container body 2 is sucked through the liquid suction pipe 13, and in the air chamber A, the air outside the container is sucked through the suction hole F to be in a preparation state for bubbling. By repeating the operation of pressing down the nozzle body 4 and releasing the operation, a desired amount of foam can be discharged from the discharge port 42 through the foam passage G of the nozzle body 4.

By repeating the operation of pushing down the nozzle body 4 and releasing the operation, the liquid in the container body 2 is sucked up from the liquid suction pipe 13 into the liquid chamber B. The headspace volume of the
Although the head space is in a negative pressure state as it is, the air hole E formed in the upper part of the cylinder wall of the air cylinder 52 is opened while the piston portion 73 of the air piston 7 is moving. The external air that has entered through the gap between the screw cylinder portion 34 and the stem portion (41, 71) of No. 3 is immediately sucked into the container body 2 from the air hole E,
Such a negative pressure in the headspace is immediately eliminated.

By the way, in the pump-type foam discharge container 1 of the present embodiment which operates as described above, the screw cylinder portions 34 and 44 for screwing the nozzle body 4 and the cap 3 into a locked state are provided.
A lower cover cylinder 35 having a diameter larger than that of each of the threaded cylinders 34 and 44 is formed upright from the over member 32 of the cap 3 concentrically with each other at intervals in the radial direction.
An upper cover cylinder portion 45 having a diameter larger than that of the lower cover cylinder portion 35 is formed so as to hang down from the nozzle body 4, and the over member 32 of the cap 3 further includes a lower end of the upper cover cylinder portion 45 of the nozzle body 4. An annular concave portion 36 is formed so as to oppose.

The upper cover cylinder 45 and the lower cover cylinder 35 formed on the nozzle body 4 and the cap 3, respectively,
At least radially spaced apart (preferably at least 2.0 mm apart) so that water does not enter into the gap between the two by capillary action, they are arranged concentrically, as shown in FIG. Then, with the nozzle body 4 as the lower limit position,
Screw tube portion 34 of cap 3 and screw tube portion 44 of nozzle body 4
Is screwed, the lower end of the upper cover cylinder portion 45 formed to hang down from the nozzle body 4 enters into the annular concave portion 36 formed in the over member 32 of the cap 3.

Further, even when the screw cylinder 34 of the cap 3 and the screw cylinder 44 of the nozzle body 4 are unscrewed and the nozzle body 4 is raised to the upper limit position by the urging force of the coil spring, FIG. As shown in (2), the upper end of the lower cover cylinder 35 and the lower end of the upper cover cylinder 45 slightly overlap each other in the height direction (preferably, about 2.0 to 3.0 mm). Further, in a state where the nozzle body 4 is pushed down from the upper limit position and is in a pushed down lower end position without being locked, as shown in FIG.
The lower end of the upper cover cylinder 45 of the nozzle body 4 is
Is prevented from entering into the annular concave portion 36 formed in the over member 32.

According to the pump-type foam discharge container 1 of this embodiment in which the upper cover cylinder 45, the lower cover cylinder 35, and the annular concave portion 36 are formed in the nozzle body 4 and the cap 3 as described above, respectively. When the locked state of the nozzle body 4 and the cap 3 is released and the nozzle body 4 is used in an environment where hot water or water splatters or rebounds, even if the nozzle body 4 is at the upper limit position, as shown in FIG. 3 and stem parts (41, 71) protruding upward from each other and respective screw cylinder parts 34, 44.
Is always shielded from hot or cold water that has splattered or bounced off by the upper cover cylinder 45 and the lower cover cylinder 35 so that water adheres to the outer surface of the stem portion (41, 71). The inner surface of the screw tube portion 34 of the cap 3 and the stem portion (4
1, 71) does not enter the gap between the outer surface and the outer surface.

The water adhering to the outer surfaces of the upper cover cylinder 45 and the lower cover cylinder 35 is also reduced by the upper cover cylinder 45 and the lower cover cylinder 35 being arranged at intervals in the radial direction. Since the water does not penetrate to the inside through the gap between the cylindrical portions 35 and 45 but flows downward from the respective outer surfaces, the water flows between the inner surface of the screw cylindrical portion 34 of the cap 3 and the stem portion. It does not enter the gap between the outer surface of (41, 71).

On the other hand, by providing the upper cover cylinder 45 and the lower cover cylinder 35, the nozzle body 4 is locked to the cap 3 as compared with the comparative example shown in FIGS. Although the lower limit position of the nozzle body 4 at this time becomes higher, as shown in FIG. 1, the lower end of the upper cover cylinder portion 45 of the nozzle body 4 enters the annular concave portion 36 of the cap 3 in the locked state of the nozzle body 4. As a result, the protrusion of the nozzle body 4 upward from the cap 3 in the locked state is equivalent to the amount of the upper cover cylinder 45 inserted into the annular concave portion 36 as compared with the case where the annular concave portion 36 is not provided. The height of the entire container can be made as small as possible.

Further, as compared with the case where the annular concave portion 36 is not provided, instead of increasing the stroke of pushing down the nozzle body 4 to increase the amount of foam discharged at one time, and instead of increasing the stroke of pushing down the nozzle body 4, The lengths of the screw tube portions 34 and 44 and the length of the bubble passage G can be reduced.

Further, in this embodiment, as shown in FIG. 6, the lower end of the upper cover cylinder portion 45 of the nozzle body 4 is closed at the lower end position of the nozzle body 4 in the unlocked state. The pumping operation is performed in a state in which water is accumulated in the concave portion 36 on the upper surface of the cap 3, such as during or immediately after showering near the container, by preventing the liquid from entering the concave portion 36. (Depressing and releasing the nozzle body 4)
6 is lifted by the upper cover cylinder 45 of the nozzle body 4, and the lower cover cylinder 35 of the cap 3 is raised.
It is never brought inside.

Although the embodiment of the pump-type discharge container of the present invention has been described above, the present invention is not limited to the above-described embodiment. The present invention is not limited to the bubble discharge container that mixes and discharges air, and is applicable to a pump-type discharge container that discharges the liquid of the contents as it is. The pump mechanism is also described in the above embodiment. Not limited to this, it is also possible to implement by other conventionally known pump mechanisms, and each cover cylinder for blocking water from the outside is also integrally molded with the nozzle body and cap. It goes without saying that the specific structure can be appropriately changed in design, for example, it may be integrally connected to the nozzle body or the cap as a separate part.

[0079]

According to the pump-type discharge container of the present invention as described above, even when used in an environment in which hot water or water splatters or rebounds, the stem portion serving as a portion for introducing air into the container can be provided. The problem that water can be prevented from entering the container through the gap between the cap top plate part, and the intrusion of water from the outside deteriorates the pumping operation and changes the color and scent of the content liquid. In particular, in the case of a container that discharges foam, the foam quality may be different from the designed one due to invading water, or mold and the like may be generated inside the air cylinder and discharged. It is possible to avoid such a problem that the aroma of the foam is deteriorated. On the other hand, at the time of sale, the entire container can be made compact in the height direction by suppressing the upward protrusion of the nozzle body from the cap when the nozzle body is in the locked state as small as possible. The size of the cardboard box for packing can be reduced, so that a large display space is not required at the time of store display, and the displayed container does not become unstable.
