BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a discharge port of a discharge container which increases the pressure of a contained liquid by applying an external force and discharges the liquid by this pressure. Cosmetics such as foundation, lip color, lip cream,
It is preferable that a relatively high-viscosity liquid such as an adhesive is discharged in a small amount and wiped off with the belly of a fingertip.

[0002]

2. Description of the Related Art As a discharge container which increases the pressure of a contained liquid by applying an external force and discharges the liquid by this pressure, for example, a general container for a neutral detergent or a toothpaste is used. The deformable storage chamber is pressed from the outside, or for example, a shampoo for hair washing.
There is a general container having a pressurizing nozzle such as a container or a rinsing device, and a container using a valve structure as seen in, for example, a manually pressurized spray container.

In many of these, the amount of liquid used at one time is not small, and is discharged so as to be stored in a receiving tray, a palm, or the like. For this reason, the shape of the discharge port is merely appropriately designed so that the cross-sectional shape of the liquid to be discharged is at most desired, such as a circular hole or a star-shaped hole.

[0004] On the other hand, as described above, there is also a method in which a small amount is discharged so as not to drip from the discharge port and wiped off with a fingertip. For such things,
In view of the fact that the discharge amount itself is small, it is desirable that the discharge liquid be easily wiped off so as not to remain near the discharge port as much as possible. This is because, if the ejection amount is small, even if the remaining amount is small, the error given to the used amount becomes large.

[0005]

The gap between the elastic body and the receiver is used as a discharge port, and the wall of the elastic body connected to the discharge port has the smallest thickness of the elastic body at the center of the discharge. And a concave portion that is gently rounded and roughly corresponds to the belly shape of the fingertip. That is, the present invention increases the pressure of the liquid to be contained by applying an external force, and is a discharge port portion of a discharge container configured to discharge the liquid by this pressure, wherein a gap between the elastic body and the receiver is used as a discharge port. And a wall portion of the elastic body connected to the discharge port is a concave surface portion which is gently rounded so as to minimize the thickness of the elastic body at the central portion of the discharge, and which roughly corresponds to the belly shape of the fingertip. The discharge port portion of the discharge container described above is a gist.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. It is possible to use a container that presses the outer wall of the liquid container like a general dentifrice tube.However, this is an example of a valve adopting a preferable valve structure in terms of drying of the liquid, decay and deterioration. is there.

In FIG. 1, a container body 1 has a mouth member 2 fixed to an upper end opening. The mouth member 2 fixes the soft bag body 3 to the outer wall of the outer cylindrical portion so as to be located inside the container body 1. This fixing does not leak the liquid 4 contained in the bag 3. When the liquid 4 is discharged, the bag 3 contracts accordingly.

[0008] A piston member 5 is provided on the inner cylindrical portion of the mouth member 2.
Are fixed, and a first valve 6 is arranged on the upper part. The first valve 6 is made of, for example, an easily deformable soft plate having a “C” -shaped notch, and can be opened only above the drawing. That is, the cylinder member 7 that slides without leakage with respect to the piston member 5 is urged upward in the drawing by the spring 8, and even if the cylinder member 7 is pressed and displaced downward in the drawing, the first valve Liquid 4 above 6
Is prevented from moving toward the bag body 3 through the first valve 6, but when the cylinder member 7 moves upward due to the resilience of the spring 8 when depressed, the first valve 6 is opened so that the liquid in the bag 3 can pass through.

A second valve 9 is arranged inside the cylinder member 7. The second valve 9 can also be opened only in the upper part of the drawing, so that the liquid 4 existing above the first valve 6 is passed when the cylinder member 7 is displaced downwardly in the drawing. The nozzle body 10 is fixed on the cylinder member 7.

The nozzle body 10 includes a receiver 11 (see FIG. 2), an elastic body 12 (see FIGS. 3 to 5), and a lid 13 (see FIGS. 6 and 7).
See). Here, the receiver 11 has an inner hole 15 serving as a reservoir for the liquid 4 that has passed through the second valve 9 as a discharge passage 14 and an opening serving as an outlet of the inner hole 15 as shown in FIG. 16 and a groove 17 communicating therewith. The upper portion of the groove 17 is a concave portion 19 having a peripheral wall 18 (a part of the peripheral wall 18 extends to the outer edge of the upper surface of the receiver 11), and a rib 20 is formed on the bottom surface of the concave portion 19. Having. The rib 20 is formed in an appropriate shape at a portion where the tightness with the elastic body 12 is required. In addition, the lid 1
3 has a projection 21 for fitting.

The elastic body 12 is made of silicone rubber, SBR,
It is made of butyl rubber or the like, and has a storage portion 22 in the concave portion 19 of the receiver 11 on the bottom surface side (see FIGS. 3 and 4). That is, the periphery of the storage portion 22 is depressed so as to fit with the peripheral wall of the concave portion 19 of the receiver 11. In addition, a part of the storage portion 22 has a concave portion 23 of the opposite direction that is continuous with the concave portion 19 of the receiver 11.
The recess 23 is partially cut out of the slope 24 of the storage section 22. In FIG. 4, a dotted line and a dashed-dotted line respectively indicate a contact portion with the edge of the recessed portion 19 of the receiver 11 and a contact area with the rib 20 of the receiver 11 (actually, in a state of elastic deformation). Therefore, the width of the concave portion 23 is gradually reduced so that it looks like an isosceles triangle in FIG. 4 in order to suppress drying of the liquid as much as possible. Reference numeral 25 denotes a through hole for fitting the receiver 11 and the lid 13,
6 considers that the shape of the molded article will not be stable if the wall thickness is partially increased during the injection molding.
5 are provided to adjust the degree of elastic deformation
Is a part that looks like a horizontally long "E" shape). Further, the dot portion in FIG. 5 indicates that the pressing force (clamping force due to the fitting between the receiver 11 and the lid 13) received from the lid 13 is stronger than the surroundings. The elastic body 12 has a concave portion 27 on the upper surface side, which will be described later.

The cover 13 has a projection 2 on the inner surface 28 of the receiver 11.
1 and a fitting portion 29. The inner surface 28 is a gentle rounded concave portion as a whole, and the dotted portion in FIG. 7 is a portion that applies a strong contact force to the elastic body 12. This corresponds to the portion with a dot in FIG.
However, the cutout portion 30 prevents the inside from applying a force to the elastic deformation of the elastic body 12. Of course, the lid 13
Can be omitted if the receiving body 11 and the elastic body 12 can be sufficiently fixed.

FIGS. 8 and 9 show the relationship between the receiving body 11, the elastic body 12, and the lid 13 in an enlarged manner. Storage part 22 of elastic body 11
Slope 24 is in contact with the edge of the concave portion 19 of the receiver 11 so as to enclose the concave portion 23. Although shown as the contact portion 31, this contact is elastic, and when an external force is applied to displace the nozzle body 10 downward to increase the pressure of the liquid 4 accumulated in the inner hole 15, the contact of the elastic body 12 is received. At this contact portion 31 where the elastic contact force against the body 11 is weak,
And a partial gap is formed, through which the liquid passes. That is, the contact portion 31 is a valve. The portion following this portion is a gap 32 as a liquid reservoir. The end of the gap 32 is a discharge port. here,
As shown in FIG. 9, the gap 32 has a wide width, but gradually narrows from the center toward both sides in the width direction. When a small amount of liquid is ejected without being dropped, it is preferable that the liquid can be spread in the width direction in accordance with the degree of pressurization so that the ejection amount can be adjusted to some extent. That is, the width of the liquid when passing through the contact portion 31 is almost equal to the width of the concave portion 19 of the receiver 11 and the width of the gap 3
In FIG. 2, since the capillary force which continues to accumulate the liquid at both ends in the width direction is strong, the opening of the gap 32 which is the discharge end is discharged by the strength of the liquid when passing through the contact portion 31. The shape of the flowing liquid changes.

Now, the concave portion 27 provided on the elastic body 12 will be described. As shown in FIG. 9, the concave surface portion 27 is gently rounded at the end of the gap 32, that is, at the discharge port, so that the thickness of the elastic body 12 at the center thereof is minimized. The entire discharge port does not always function as a discharge section, but rather may be in a discharge state as shown in FIG. 10. In addition, the discharge port is not illustrated here. Considering the case where is a pinhole, it means "to minimize the thickness of the elastic body at the central portion of the discharge". Press, for example, FIG.
When the liquid is discharged in a state like 0, and the liquid is wiped off with the other fingertip, the concave portion 27 becomes the liquid wiping surface at this time. As long as the concave shape of the concave portion 27 corresponds to the shape of the belly of the fingertip to some extent together with the soft touch by the elastic deformation of the elastic body 12, the liquid can be prevented from spreading and remaining. That is, the concave portion 27 substantially corresponds to the belly shape of the fingertip. Incidentally, the illustrated concave surface portion 27 has a linear shape (see FIG. 8) so as to have a partial shape of the side wall of the cylinder, but may have a partial shape of a spherical surface. It may be smoothly continuous with another wall surface.

[0015]

As described above, the discharge port of the discharge container of the present invention has a gap between the elastic body and the receiver as a discharge port.
Also, the wall surface of the elastic body connected to the discharge port is a concave surface part which is gently rounded so as to minimize the thickness of the elastic body at the central part of the discharge, and which roughly corresponds to the belly shape of the fingertip. Since the liquid is ejected in a small amount so that it does not drip from the ejection port and wiped off with your fingertips, even when the ejection amount itself is small, it is easy to wipe the ejection liquid so that it does not remain near the ejection port as much as possible And the original function of discharging a small amount and using a small amount can be effectively exhibited.
