Description

The present invention relates to a backflow prevention stopper and a container comprising the backflow prevention stopper.
In this specification, the vertical direction of the container 1 itself is referred to based on the posture in which the container 1 is erected so that the container mouth part 2 faces upward, and the container 1 is attached to the container mouth part 2 at this time. The vertical direction of the backflow prevention plug 5 is referred to based on the posture of the backflow prevention plug 5.

A spherical sealing surface that includes an elastic film body having a discharge port and a plug member disposed in the elastic film body as a backflow prevention plug provided in the container mouth, and the plug member elastically adheres to the elastic film body Further, there is known a structure in which thick portions and thin portions are alternately arranged in the circumferential direction around the discharge port side of the elastic film body (see Patent Document 1, etc.).
In this known backflow prevention plug, the elastic film body formed of an elastic material is more easily expanded and stretched in the thin wall portion than in the thick wall portion around the discharge port. When the body is pushed out, as the internal pressure of the container rises, the fluid is discharged from the discharge port while pushing the thin portion from the plug member.

In addition, since a thick part is harder to swell and extend than a thin part, there exists an effect | action which regulates the movement to the discharge direction of a plug member at the time of discharge of a fluid.
In this type of backflow prevention stopper and a container provided with this backflow prevention stopper, the fluid once discharged does not flow back into the container, so the fluid in the container is a germ in the atmosphere. There is an advantage that it will not be contaminated or oxidized.
JP 2005-219780 A

Conventionally known backflow prevention stoppers are employed in containers for low viscosity fluids such as eye drops. However, when a container having this backflow prevention port plug is filled with a high-viscosity or ultra-high-viscosity fluid (for example, a hair conditioner such as a treatment), the thin portion is plugged around the discharge port of the elastic film body. In order to push open from the member, a strong extrusion pressure (internal pressure in the container) is required, and the discharge direction is not fixed. As a result, the discharge becomes extremely difficult. In particular, it has been impossible to discharge fluids for women, elderly people, children, and the like.
Further, the fluid remains between the thin wall portion and the plug member, and thereafter the adhesion of the elastic film body to the plug member is reduced or deteriorated, and the basic functions such as backflow prevention and prevention of contamination of the fluid in the container are obtained. In some cases, the effects could not be obtained.

In addition, even after the discharge of the fluid was finished, the fluid sometimes oozed out from the discharge port. In this case, the exuded fluid flowed to the outer surface of the container, leading to the container itself becoming dirty.
This invention is made | formed in view of the said situation, Comprising: It aims at providing the backflow prevention spigot and container which were suitably used also for the fluid of high viscosity thru | or ultrahigh viscosity.

In order to achieve the above object, the present invention has taken the following measures.
That is, the backflow prevention plug according to the present invention has a plug member and an elastic film body. The plug member is formed by forming an upper hemisphere at the upper part of the trunk and a lower hemisphere at the lower part of the trunk so that the equatorial plane formed around the trunk body has a maximum diameter. . The elastic film body is fitted to a region extending from the upper hemisphere to the lower hemisphere from the upper hemisphere to the stopper member, and a discharge port communicating with the outside is formed in a portion covering the upper hemisphere. An inflow opening that opens the lower end of the surface downward is formed.

The backflow prevention stopper plug according to the present invention thus configured is attached to the container mouth portion by a cap that is fitted around while holding an expansion space around the elastic membrane body.
The elastic membrane body is provided with a top seal portion that makes surface contact while generating an elastic force with respect to the upper hemisphere of the plug member, and a hem seal portion that makes contact with the lower hemisphere while generating an elastic force. It has been.
The top seal portion is in surface contact with at least the upper end portion of the upper hemispherical surface, and a discharge port is arranged in the surface contact region. The hem seal portion contacts the lower hemispherical surface in a state of making a round, and an inflow port is formed below the contact region. Due to the hem seal portion, an elastic force directed to the discharge port acts on the plug member.

  With the backflow prevention plug having such a configuration, the elastic film body comes into contact with the plug member at two locations, the top and bottom seal portions and the bottom seal portion. The plug member is double-sealed by such contact between the upper and lower portions. Therefore, the fluid can be surely sealed. Unlike the prior art, the elastic film body is not provided with a thick portion, so that even a fluid having a high viscosity or an ultra-high viscosity can be discharged easily and reliably. This is because the internal pressure of the container rises due to the pressing force at the time of discharge, and the elastic film body easily swells into the expansion space, and the discharge pressure is lowered by expanding the flow path.

  In the elastic film body, it is preferable that the skirt seal part, the expansion space, and the top seal part are formed with substantially the same thickness. By doing so, even a fluid having a high viscosity or an ultrahigh viscosity can be easily and reliably discharged. This is because the internal pressure of the container rises due to the pressing force at the time of discharge, and the elastic film body easily swells into the expansion space, and the discharge pressure is lowered by expanding the flow path. Further, since the sealing after the completion of discharge can be performed reliably, it is possible to prevent the fluid from seeping out from the outside of the discharge port, and the outer surface of the container is not contaminated by the fluid that has exuded.

The bottom seal part and the top seal part of the elastic film body are preferably formed with a thickness of 1.5 mm or less (more preferably 0.3 mm or less).
The hem seal portion of the elastic film body may be formed by an annular projection that protrudes inward in the radial direction when a continuous groove is formed around the entire outer peripheral surface of the elastic film body.
In the bottom seal portion formed by such an annular protrusion, the contact state with respect to the plug member becomes a line contact state, and the sealing performance is enhanced due to the high surface pressure. Therefore, it is suitable for a fluid having a high viscosity or a super high viscosity.

An annular space may be formed between the top and bottom seal portions and the bottom seal portion of the elastic film body so as to be separated from the lower hemispherical surface of the plug member over the entire circumference thereof. By doing so, the elastic film body easily expands into the expansion space, and the flow path is widened, so that the discharge pressure is reduced.
The elastic film body can be provided with a flange portion projecting outward in the radial direction along the entire circumference around the top seal portion. By providing this flange portion, it is possible to hide the upper end of the cap and the container mouth at the time of attachment, so that the appearance of the entire container can be improved.
The upper end surface of the elastic film body is preferably formed as a flat surface perpendicular to the central axis passing through the center of the equatorial plane of the plug member.

By doing so, wiping when a fluid adheres around the discharge port becomes easy, and clean wiping can be performed.
The elastic film body is preferably formed of butyl rubber. The elastic film body may be formed of a highly stretchable material such as silicon rubber or thermoplastic elastomer in addition to butyl rubber, and is appropriately selected depending on the contents contained in the container and the physical properties of the fluid. In addition, the elastic film body itself can be colored and identified according to the intended use, and the flow of the fluid can be visually confirmed by changing the color of the plug member when silicon rubber is used for the elastic film body. Is also possible.

On the other hand, in the container according to the present invention, the above-described backflow prevention port plug according to the present invention is attached to the container mouth portion through a cap that is fitted around while holding an expansion space around the elastic membrane body. It is.
The elastic film body may be provided with a mounting seat that protrudes radially outward at a position below the bottom seal portion, and the elastic film body may be configured to sandwich the mounting seat of the elastic film body between the cap and the container mouth portion. As a result, the structure can be simplified and the attachment can be made securely.
Further, the cap may be provided with backup portions that contact the top seal portion of the elastic film body at a plurality of locations in the circumferential direction from above. By providing this backup part, the elastic film body can be excessively swollen and the extrusion of the plug member in the discharge port direction can be restricted.

This container can be used for high-viscosity or ultra-high viscosity fluids. As the ultra-high viscosity fluid, a fluid having a viscosity of 1000 CPS (centipoise) or more and 10000 CPS or less may be used so as to include the viscosity of a hair conditioner such as a treatment.
The elastic film body preferably contains an antibacterial agent. Moreover, it is desirable that the plug member contains an antibacterial agent. The cap preferably contains an antibacterial agent. Thereby, a stopper and a container can be used further hygienically. This antibacterial agent is desirably 3% or less by mass percentage.

  The backflow prevention stopper and the container according to the present invention can be suitably used without causing the conventional problems even in a fluid having a high viscosity or an ultrahigh viscosity.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows one embodiment of a container 1 according to the present invention, and FIGS. 2 to 5 show a backflow prevention stopper plug 5 attached to the container mouth portion 2 via a resin cap 3 in the container 1. Is shown. The container main body 6 provided with the container opening 2 can be contracted and deformed by pressing the abdomen center 6a. This container 1 is mainly used for storing and discharging a fluid having an ultrahigh viscosity of about 1000 CPS to 10000 CPS, such as a hair conditioner such as a conditioner. It can also be used when a low-viscosity or high-viscosity fluid is targeted.

The backflow prevention plug 5 includes a plug member 10 and an elastic film body 11.
The plug member 10 is formed of a resin, for example, a synthetic resin such as polyethylene, nylon, or polypropylene, or rubber (such as butyl rubber). An upper middle portion of the plug member 10 has a circular body in plan view, and an upper hemisphere is formed on the upper part of the body. A surface 10a is formed, and a lower hemispherical surface 10b is formed at the lower part of the body. An equatorial plane 10c is formed around the trunk, that is, between the upper and lower hemispherical surfaces 10a and 10b, and the equatorial plane 10c is the maximum diameter position of the plug member 10.

The upper hemispherical surface 10a, the lower hemispherical surface 10b, and the equatorial surface 10c do not have physically clear boundaries, but the region of the plug member 10 having the maximum diameter is the equatorial surface 10c, and the upper portion thereof. The region that is reduced in diameter is defined as the upper hemispherical surface 10a, and the region that is reduced in diameter below the equator surface 10c is defined as the lower hemispherical surface 10b. Although the plug member 10 in the figure is shown as a spherical shape as a whole, it may be a long spherical shape or an elliptical sphere whose major axis is the vertical direction.
The size of the plug member 10 is preferably larger than that for a low-viscosity fluid such as eye drops, and is equal to or larger than a spherical shape having a diameter of 4 mm. In the present embodiment employing a spherical shape, the diameter is about 6 mm.

  The elastic film body 11 is formed of rubber (butyl rubber or the like) or the like, and is fitted to the plug member 10 in a region extending from the upper hemispherical surface 10a to the lower hemispherical surface 10b beyond the equator surface 10c. The elastic film body 11 is desirably set to a JISA hardness of 40 degrees or less, and more preferably a JISA hardness of 30 degrees or less. In the elastic film body 11, a discharge port 13 communicating with the outside is formed at a portion covering the upper hemispherical surface 10 a of the plug member 10. Further, the lower end portion of the lower hemispherical surface 10b is opened downward toward the lower side of the plug member 10, whereby the inlet 14 is formed in this open portion.

The cap 3, the plug member 10, and the elastic film body 11 contain an antibacterial agent. The antibacterial agent is added (kneaded) to the main raw material when the cap 3, the plug member 10, and the elastic film body 11 are molded.
As the antibacterial agent, for example, antibacterial zeolite is used. An antibacterial zeolite refers to a zeolite having an antibacterial metal ion. Examples of zeolite include A-type, X-type, and Y-type. Zeolite has various ions such as Na, Ca, and K in its molecule and has a specific ion exchange amount. For example, by replacing the ions with antibacterial metal ions, Zeolite. As the antibacterial metal ion, silver zeolite is preferable.

Examples of preferable silver zeolite include Kanebo and Bactekiller manufactured by Fuji Chemical Co., Ltd. Another example of the antibacterial agent is Bioden SK40H manufactured by Daiwa Chemical Industry Co., Ltd.
The antibacterial agent kneaded into the cap 3, the plug member 10, and the elastic film body 11 is preferably 0.03% or more and 3% or less, and more preferably 0.03% or more and 2% by mass percentage (weight% concentration). The following is preferable, and more preferably 0.03% or more and 1% or less.
When the antibacterial agent is kneaded into the cap 3, the plug member 10, and the elastic film body 11, antibacterial properties against germs such as Escherichia coli and Staphylococcus aureus are improved.

In the elastic film body 11, a portion covering the upper hemispherical surface 10 a of the plug member 10 is in surface contact with at least the upper end portion of the upper hemispherical surface 10 a while generating an elastic force, thereby forming a top seal portion 17. The above-described discharge port 13 is arranged in the top seal portion 17 (in the surface contact area). The discharge port 13 is formed by a slit having a single character shape, a trifurcated (Y shape) shape, or a cross shape. Depending on the viscosity of the fluid, for example, a small hole may be used.
Further, in the elastic film body 11, the portion covering the lower hemispherical surface 10 b of the plug member 10 is in contact with the lower hemispherical surface 10 b while making an elastic force, thereby forming the hem seal portion 18. By this skirt seal portion 18, the plug member 10 is subjected to an elastic biasing action that is pushed up toward the discharge port 13, and the adhesion between the crown seal portion 17 and the upper hemispherical surface 10 a of the plug member 10 is enhanced. The inlet 14 described above is formed below the bottom seal 18 as a boundary.

The skirt seal portion 18 is formed by an annular protrusion 20 that protrudes inward in the radial direction in accordance with the formation of the circumferential groove 19 that is continuous over the entire outer peripheral surface of the elastic film body 11. Therefore, the hem seal portion 18 is in a line contact state with respect to the plug member 10 and has a high surface pressure, thereby improving the sealing performance.
An annular space 21 is formed on the upper peripheral edge of the annular protrusion 20. The annular space 21 is configured such that the upper and lower portions of the top seal portion 17 and the bottom seal portion 18 are separated from the lower hemispherical surface 10b on the entire circumference. Therefore, in the skirt seal portion 18 formed by the annular protrusion 20, the elastic biasing action that pushes the plug member 10 toward the discharge port 13 is effective, and the top seal portion 17 and the upper hemisphere of the plug member 10. The effect that the adhesiveness with the surface 10a is further improved is obtained. As a result, the plug member 10 is double-sealed to ensure high sealing performance.

The elastic film body 11 is further provided with a mounting seat 23 projecting radially outward at a position below the hem seal portion 18 and a flange portion 24 projecting radially outward around the entire head seal portion 17. It has been. The mounting seat 23 is used when being attached to the container mouth portion 2.
The flange portion 24 is where the upper surface forms the upper end surface as the elastic film body 11, and at the same time, when the backflow prevention plug 5 is attached to the container mouth portion 2, the tip portion as the container 1 is formed. is there. The upper surface of the flange portion 24 (the upper end surface of the elastic film body 11) is formed as a flat surface perpendicular to the central axis P passing through the center of the equatorial surface 10c of the plug member 10.

The bottom seal portion 18 and the top seal portion 17 are formed to have substantially the same thickness, and the thickness dimension is formed to be 1.5 mm or less. More preferably, the thickness is 0.3 mm or less. The thickness dimension is preferably 0.1 mm or more.
On the other hand, the cap 3 is a short cylindrical hollow body on which the backflow prevention stopper plug 5 having the above-described configuration can be fitted, and has an inner diameter that can hold the expansion space 25 around the elastic membrane body 11. In addition, an inwardly-facing stepped surface 26 that can come into contact with the mounting seat 23 of the elastic film body 11 from above is formed on the inner skirt.

On the inner peripheral surface of the annular wall 27 on the skirt side from the inward stepped portion surface 26, a male screw, a concave / convex engaging portion, a bonding margin portion or the like used for coupling with the container mouth portion 2 is provided.
In contrast, the container mouth portion 2 is provided with a cylindrical neck portion 30 having a fitting relationship with the annular wall 27 on the hem side of the cap 3, and a female screw used for coupling with the cap 3 is provided on the outer peripheral surface of the cylindrical neck portion 30. And a concave-convex engaging portion or a bonding margin portion are provided. A shoulder 31 that faces the inwardly stepped surface 26 of the cap 3 is provided on the upper side of the cylindrical neck 30, and a through hole 32 is formed at the center of the shoulder 31.

Accordingly, when the cap 3 is fitted into the container mouth 2 with the backflow prevention port plug 5 incorporated in the cap 3 and coupled, the backflow prevention port plug 5 has the mounting seat 23 facing the cap 3 inward. It is sandwiched between the stepped portion 26 and the shoulder 31 of the container mouth portion 2.
The cap 3 is provided with backup portions 33 that contact the top seal portion 17 of the elastic membrane body 11 from above at a plurality of locations in the circumferential direction. The extrusion of the plug member 10 in the direction of the discharge port 13 is restricted. In this embodiment, the backup part 33 shall protrude in the planar view rectangular shape from four places every 90 degrees in the circumferential direction. In addition, the shape, the number of formation, etc. of the backup part 33 are not limited.

In this way, when the backflow prevention stopper plug 5 is attached to the container mouth portion 2 and the cap 3 is fitted around the container opening portion 2, the expansion space 25 is held around the elastic film body 11 of the backflow prevention stopper plug 5. In addition, the backup portion 33 is in contact with the top seal portion 17 of the elastic film body 11 from above.
In addition, the flange part 24 provided in the elastic film body 11 hides the backup part 33 provided in the cap 3 and the appearance of the container 1 as a whole is improved.
In the container 1 constructed as described above, assuming that the container body 6 is filled with a fluid having a high viscosity or an ultrahigh viscosity, the container body 6 is filled when the abdomen center 6a of the container body 6 is pressed and deformed. The fluid thus formed is pushed out toward the backflow prevention plug 5 and is pushed down to the inlet 14 of the backflow prevention plug 5 through the through hole 32. Then, the fluid pushes and opens the bottom seal portion 18 of the elastic film body 11 from the lower hemispherical surface 10b of the plug member 10, and moves toward the top seal portion 17 through the equator surface 10c. And the top seal part 17 which is between the backup parts 33 pushes open from the upper hemispherical surface 10a, and is discharged from the discharge port 13.

If the pressing of the abdomen center 6a of the container main body 6 is stopped, the container main body 6 also eliminates the extrusion pressure of the fluid against the backflow prevention plug 5. Therefore, the elastic film body 11 returns to the state where it comes into surface contact with the plug member 10 at two locations, the top seal portion 17 and the bottom seal portion 18, so that the fluid is reliably sealed.
At this time, even when the fluid is attached around the discharge port 13, the upper end surface of the flange portion 24 provided around the discharge port 13 is formed flat, so that the attached fluid is wiped off. Easy and clean.

In the elastic film body 11, the bottom seal portion 18 and the top seal portion 17 have substantially the same thickness and a thickness of 1.5 mm or less (preferably 0.3 mm or less). Even a fluid having a viscosity can be easily and reliably discharged. Moreover, since the sealing after the completion of the discharge can be performed reliably, it is possible to prevent the fluid from oozing out on the outer side of the discharge port 13, and the outer surface of the container 1 is not contaminated by the oozed fluid.
As shown in FIG. 6, in the backflow prevention plug 5, the elastic membrane body 11 is formed as a cylinder having an inner diameter smaller than the diameter of the plug member 10, and the plug member 10 is inserted into the cylinder. By inserting, you may make it closely_contact | adhere to the outer surface of the plug member 5 producing elastic force.

  By the way, this invention is not limited to the said embodiment, It can change suitably according to embodiment.
