[Detailed description of the invention]

[0001]

In the present invention, an external force is applied to increase the pressure of a contained liquid, and the valve is opened by the pressure of the liquid.
The present invention relates to a discharge port structure of a discharge container configured to discharge liquid using an opening of a liquid reservoir portion connected to the valve as a discharge end. Foundation, lip color, lip clean
It is preferable to use a relatively high-viscosity liquid, such as cosmetics such as gums, mayonnaise, paints, adhesives, and toothpastes.

2. Description of the Related Art As a discharge container which increases the pressure of a liquid to be contained by applying an external force and discharges the liquid by this pressure, for example, a container for an adhesive, a neutral detergent, a toothpaste or the like is generally used. For example, there is a type in which a typical deformable storage chamber is pressed from the outside, or a type having a pressurizing nozzle, which is a general container such as a shampoo or a rinse for hair washing. In the container, the contained liquid is continuous up to the discharge end,
For example, problems such as drying and spoilage and deterioration are likely to occur depending on the type of liquid.

[0003] On the other hand, if a valve structure is used as seen in a manually pressurized spray container or the like,
This can be improved if the container is provided with a valve that opens with the pressurized liquid. If this valve is provided so as to be a discharge end, the shape of the discharged liquid can be regulated. For example, if the elastically deformable film body provided with a single slit is used as a valve and the slit of the film body is opened by the pressure of the liquid, the liquid to be discharged has a flat shape. Here, it is needless to say that the shape of the liquid to be discharged can also be regulated by providing a liquid reservoir having an opening having an arbitrary shape as a discharge end, which is connected to the valve further on the discharge destination side than the valve.

However, it is not satisfactory to change the shape in accordance with the amount of liquid to be discharged. Specifically, it cannot be made narrow when used in a small amount, and wide when used in a large amount. At best, the shape of the liquid to be ejected can be slightly changed by consciously or unconsciously changing the pressure for pressurizing the liquid.

Therefore, the present invention provides a discharge port of a discharge container which satisfies the discharge of a liquid which becomes narrower for a small amount of use and wider for a large amount of use if the pressure for pressurizing the liquid is changed. It is intended to provide a partial structure.

[0006]

According to a first aspect of the present invention, a valve is formed such that a maximum width of a liquid passing therethrough is determined by an elastically deformable receiver and a plug, and a liquid reservoir is formed.
The gap gradually narrows from the center toward both sides in the width direction, but is wider than the maximum width of the liquid that has passed through the valve, and is formed as a gap having a shorter distance from the valve to the discharge end. That is, in the present invention, the pressure of the liquid to be contained is increased by applying an external force, the valve is opened by the pressure of the liquid, and the liquid is discharged using the opening of the liquid reservoir connected to the valve as the discharge end. In the discharge port structure of the discharge container, the valve is formed so that at least one of the elastic member and the plug body determines the maximum width of the passing liquid, and the liquid reservoir is formed. The discharge port structure of the discharge container, which gradually narrows from the center toward both sides in the width direction but is wider than the maximum width of the passing liquid, and is formed as a gap in which the distance from the valve to the discharge end is short.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 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 receiving body 11 (see FIG. 2), a plug 12 (see FIGS. 3 to 5), and a lid 13 (see FIGS. 6 and 7). As described sequentially, the receiver 11
As the discharge passage 14, an inner hole 15 serving as a reservoir for the liquid 4 having passed through the second valve 9 and a groove 17 communicating with an opening 16 which is an outlet of the inner hole 15 as shown in FIG. Have. Groove 1
7 has a peripheral wall 18 (a part of the peripheral wall 18 is
(Which extends to the outer edge of the upper surface). The rib 20 is formed in an appropriate shape at a portion where the sealing performance with the plug 12 is required to be enhanced. In addition, a projection 21 for fitting to the lid 13 is provided on the upper surface.

The plug 12 is made of silicone rubber, SB
It is made of an elastically deformable material such as R or butyl rubber, and has a storage portion 22 in the concave portion 19 of the receiver 11 on the bottom side (see FIGS. 3 and 4). That is, the periphery of the storage portion 22 is depressed and fits with the peripheral wall of the concave portion 19 of the receiver 11. Also,
A part of the storage part 22 is a concave part 23 in the opposite direction to the concave part 19 of the receiving body 11, and the concave part 23 is partially cut out of a slope 24 of the storage part 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, it does not become a "line"). Reference numeral 25 indicates a through hole for fitting the receiver 11 and the lid 13.

The plug 12 has a projection 26 on the upper surface side. The protruding portion 26 is a portion that looks like a horizontally long “E” shape in FIG. 5 and takes into account that the shape of the molded product becomes unstable if the thickness is partially increased during injection molding. It is provided to adjust the degree of elastic deformation of the body 12. Further, the stopper 12 has a larger diameter than the receiver 11 and the lid 13 as a whole, but in particular, the right portion of the drawing (eg, FIG. 5) on the discharge destination side projects to the upper surface side. The upper lip 27 is formed. In FIG. 5, a portion with a dot indicates a portion where the pressing force received from the lid 13 (a clamping force due to the fitting between the receiver 11 and the lid 13) is stronger than the surroundings.

Next, the lid 13 has a fitting portion 29 with the projection 21 of the receiver 11 on the inner surface 28. The inner surface 28 is a gentle rounded concave portion as a whole, and the portion with dots in FIG. 7 is a portion that applies a strong contact force to the plug 12. This corresponds to the portion with a dot in FIG. However, the cutout 30 prevents the inside from applying force to the elastic deformation of the plug 12.

FIGS. 8 and 9 show the receiving member 11 and the plug 1 described above.
2. The relationship by the lid 13 is shown in an enlarged manner. The slope 24 of the storage portion 22 of the plug 11 is in contact with the edge of the recess 19 of the receiver 11 so as to enclose the recess 23. Although shown as the contact part 31, this contact is elastic,
When an external force is applied to displace the nozzle body 10 downward to increase the pressure of the liquid 4 stored in the inner hole 15, the stopper 12 has a weak elastic contact force with the receiver 11 at the contact portion 31. 11 and a partial gap is formed, through which the liquid passes. That is, the contact portion 31 is a valve. The part following this part is a gap 32 as a liquid pool part.
It has become. As shown in FIG. 9, the gap 32 has a shape that is wide, but gradually narrows from the center toward both sides in the width direction. Here, the width of the gap 32 is sufficiently larger than the width of the concave portion 19 of the receiver 11.

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. Further, in the gap 32, the capillary force that continues to store the liquid is stronger at the ends on both sides in the width direction. Therefore, the shape of the liquid discharged from the opening of the gap 32, which is the discharge end, changes depending on the strength of the force of the liquid when passing through the contact portion 31. That is, when the force of the liquid is weak, the gap becomes narrower through only the center of the gap 32 where the capillary force is relatively weak (see FIGS. 10 and 11). However, it is wide (see FIGS. 12 and 13).

An example has been described above.
Various modifications can be made without departing from the gist of the present invention. For example,
The lid 13 is not required when the receiver 11 and the plug 12 can sufficiently secure the lid 13 alone. Further, in order to use the liquid accumulated in the gap 32 when the upper lip 27 is pressed, the stopper 12 is made of a material that can be disconnected and deformed. At least one of the tip 12 and the tip 12 may be elastically deformable. Furthermore, the width of the liquid when passing through the contact portion 31 is more constant when the flow resistance in the central portion is smaller, so the recessed portion 23 is provided in the plug body 12, but in order to make it easier to flow in the central portion, For example, as shown in FIGS. 14 and 15, the central portion of the cutout portion 30 of the lid 13 is further defined as an important cutout portion 33. You can also do so. Alternatively, conversely, the concave portion 23 can be omitted. In addition, the receiving body 11 may not have the recessed portion 19, and may have a valve formed by simply abutting the receiving body 11 and the plug 12 on a plane / split side. . It is possible to determine the width of the liquid passing through the valve (the maximum width if this width changes), and it is appropriate as long as the width is smaller than the width of the gap continuously provided therewith. Further, the length of the gap 32 may be appropriately set within a short distance according to the viscosity of the liquid.
In addition, it is also possible to use a container in which the outer wall of the liquid container is pressed like a general toothpaste tube.
