[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a discharge port portion of a discharge container that applies pressure to a fluid stored in a storage chamber and discharges the fluid from a discharge port. Here, examples of the fluid to be discharged include lip color, lip cream, foundation, hair shampoo, rinse, adhesive, toothpaste, paint, ink solution, and handwriting correction fluid.

[0002]

[Prior art]

 Examples of the discharge container of the above-mentioned type include, for example, a general container for an adhesive, a neutral detergent, toothpaste, etc., in which a deformable storage chamber is pressed from the outside, or, for example, There are various types of general containers for shampoos and rinses that have a pressure nozzle at the top.

Further, there is a container of this type provided with a valve portion for opening and closing the fluid passage. This valve section is preferable to prevent deterioration of the contained fluid over time, drying, and leakage, and the valve body such as a ball or rod is supported by elastic force or the self-weight of the valve body. It is used to urge it toward the valve seat.

[0004]

[Problems to be solved by the device]

 Since the valve portion cannot prevent deterioration of the fluid existing on the discharge destination side of the valve portion, it is preferable that the valve portion is provided at the discharge port portion and as close to the discharge end portion as possible. Further, the present invention is designed to open the valve by the discharge pressure of the fluid, but do not close the valve with a strong force so that the valve can be opened without increasing the discharge pressure of the fluid. Moreover, it is preferable that the valve can be surely closed before the use is started. In addition, the structure for forming the valve portion is preferably as simple and inexpensive as possible.

[0005]

Means for Solving the Problems The valve portion is made of a hard member and an elastically deformable soft member. A rib is provided on the hard member, and the soft member elastically abuts on the rib. Of course, when the fluid discharge pressure is applied, the soft member elastically deforms and forms a gap with the rib. Further, in the initial state, a silicone oil film is provided. That is, the present invention is a discharge port portion of a discharge container configured to discharge a fluid stored in a storage chamber by applying pressure, and has a valve portion including a hard member and an elastically deformable soft member. Here, the valve portion is provided by elastically abutting the soft member so as to form a gap when the discharge pressure of the fluid is applied to the rib provided on the hard member. The gist is the discharge port of a discharge container that has a silicone oil film.

【Example】

 An example will be described with reference to the accompanying drawings. In FIG. 1, the mouth member 2 is fitted into the upper end opening of the container body 1 and is prevented from coming off by the lid body 3 screwed to the container body 1. A soft bag body 4 is attached to the outer wall of the outer tubular portion of the mouth member 2 so that the fluid 5 to be contained therein is located inside the container body 1. The bag body 4 contracts in response to the discharge of the fluid 5, and it is preferable that air is not mixed as much as possible.

A pipe 6 extending into the bag body 4 is attached to the lower end of the inner tubular portion of the mouth member 2, and a ball 7 is placed on the pipe 6. Further, the piston member 8 having the inner cylindrical portion of the mouth member 2 as a cylinder is urged upward by the elastic member 9 and is engaged with the lid body 3 to be prevented from coming off. The ball 10 is also mounted in the inner hole of the piston member 8.

That is, what is shown is an example of a discharge container having a pump structure, and by pressing the nozzle body 11 attached to the top of the piston member 8, it resists the elastic force of the elastic member 9. When the piston member 8 is lowered, the fluid 5 accumulated on the ball 7 pushes up the ball 10 to make a gap and discharge the fluid. Further, the pressure of the nozzle body 11 is released and the piston member 8 is removed. When raised, the fluid 5 in the bag body 4 passes through the pipe 6 and pushes up the ball 7 to form a gap and collect in the space below the ball 10.

Here, the discharge container of the present invention may be, for example, a type that presses the deformable storage chamber from the outside, but as described above, the one having the pump structure is shown. Indicates that a valve portion other than the valve portion in the discharge port portion, which will be described later, may be appropriately provided.The more valve portions, the greater the resistance when the fluid is pressurized and discharged. That is because it is required to reduce the resistance of the valve. Instead of the balls 7 and 10, for example, a soft plate-like body having a “C” -shaped notch and easily deformable may be used. Also, the relationship between the piston and the cylinder can be reversed.

FIG. 2 is an enlarged view of the tip of the nozzle body 11 in FIG. 1, and FIG. 3 is a front view of the nozzle body 11. Two members are inserted and fixed through the tip opening of the nozzle body 11. The hard member 12 is located on the lower side of the drawing, and the soft member 13 is located on the upper side thereof. The hard member 12 is made of, for example, polypropylene, polyacetal, ABS resin, stainless steel, aluminum, brass, or the like that is not expected to exhibit elasticity in practice. The soft member 13 is made of silicone rubber, SBR, butyl rubber, or the like, and utilizes elastic deformation of this member.

The insertion portion of the soft member 13 into the nozzle body 11 is suppressed from being elastically deformed, but the exposed portion is easily elastically deformed at least to some extent. That is, the hard member 12 and the soft member 13 exert abutting force on each other at the joint, but in the exposed portion from the nozzle body 11, the abutting force is exerted on the exposed portion because the deformation is not suppressed by the nozzle body 11. It can be easily lowered. Of the portion where the contact force can be reduced, the fluid is discharged to the outside from the place where the contact is canceled by the pressure of the fluid discharged to the fluid passage 14 formed by the hard member 12 and the soft member 13 and the gap is formed. become.

Although not shown in FIGS. 2 and 3, the portion forming the gap, and thus the portion serving as the valve portion, is located at the portion B in FIG. 2 as enlarged in FIG. That is, a rib 15 is formed on the hard member 12, and the portion of the rib 15 is a portion where the abutting force is surely exerted as compared with the vicinity thereof, but it is the maximum when compared with other joints. Also makes it easy to form a gap. This will be described with reference to FIG. 3. Of the joints of the hard member 12 and the soft member 13, the portions indicated by reference numerals 16 and 17 are affected by the insertion into the nozzle body 11 and have a relatively large contact force. The portions indicated by reference numerals 18 and 19 are essentially irrelevant to the discharge of the fluid even when the soft member 13 is displaced upward in the drawing, and the fluid is originally positioned to be positioned. For the portions indicated by reference numeral 20, the depths of the hard member 12 and the height of the soft member 13 from the reference numerals 16 and 17 to the corresponding portions should be dimensioned. Is a part where a relatively small contact force acts.

However, even if the hard member 12 and the soft member 13 do not have a convex-concave relation with each other as shown in the drawing, for example, the rib 15 may be appropriately combined with another third member. It is possible to make the part easy to form a gap, and for example, to form a gap only in the part where the height is lowered by extending a rib whose height is reduced in part to the entire seam. The rib 15 may be a portion, and in short, a desired portion of the rib 15 may be a portion where a gap is easily formed. The non-uniformity of the closure is reduced when the abutting portion which is the valve portion between the hard member 12 and the soft member 13 is as narrow as possible in the area. Therefore, the rib drawn in the shape of an isosceles triangle is reduced. The cross section of 15 can be appropriately formed into a right triangle, a semicircle, a trapezoid, a rib that forms an arc instead of a straight line, or a rib where two corrugated corrugated sheets are combined. It may be provided.

The rib 15 of the hard member 12 and the soft member 13 contact each other to form a valve portion that can be opened even if the discharge pressure of the fluid 5 is sufficiently small, and discharge the fluid 5 when the discharge pressure is not applied. It becomes a valve part that can be surely shut off. However, in the initial state where the fluid 5 does not exist in the ribs 15, air enters even in a small gap that cannot be seen, so that the deterioration of the fluid 5 present inside from the surface area which is never narrow. May occur. It is the silicone oil film 21 shown as a dot portion in FIG. 4 that can ignore this concern. There are various silicone oils such as dimethyl silicone oil, methyl hydrogen silicone oil, methylphenyl silicone oil, and modified dimethyl silicone oil.Those that do not worry about deterioration due to the outside air are preferable, but they can be selected appropriately. If necessary, the solvent may be appropriately diluted before use. By the way, when the fluid contains silicone oil as an ingredient, for example, many cosmetics contain silicone oil to improve gloss, spread, and feel. If so, it is preferable to select the same kind if possible. The silicone oil film 21 shown in the drawing is formed on both the hard member 12 side and the soft member 13 side. For example, it may be sprayed or brushed only on the soft member 13 side. You may keep it. Further, although depending on the material, it is possible to mix the hard member 12 and the soft member 13 with the raw material so as to form a film over time on the surface of the molded product due to the migration phenomenon.

Although an example has been described above, various modifications can be made without departing from the spirit of the invention. For example, in the above-mentioned one, the rib 15 is provided slightly apart from the ejection tip because the ejection destination side of the rib 15 is the ejection fluid shape regulating portion, but the shape of the ejection liquid is not taken into consideration. In some cases, the rib 15 may be provided at the discharge tip. Also, for example, although the ejection port has a square front shape as a whole (FIG. 3), both the hard member 12 and the soft member 13 are flat, so that the front shape is flat as a whole. The shape is also appropriate such as.
