Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a low-viscosity liquid composite container containing a low-viscosity liquid such as a solvent volatilization type adhesive, a chemical liquid, food, ink and the like.

[0002]

2. Description of the Related Art Liquid adhesives, which are representative of low-viscosity liquids, include those of different types such as solvent volatilization type and humidity curing type, but plastic tubes are used for solvent volatilization type adhesives. No, and moisture-curable adhesives cannot use moisture-permeable plastic tubes. For this reason, these types of adhesives use metal tubes such as aluminum tubes and lead tubes.

However, since the metal tube has no restoring force, so-called liquid sagging occurs after the adhesive which is the content is discharged. This phenomenon becomes more prominent when the content has a low viscosity such as an instant adhesive. Further, since the metal tube has no restoring force, a recess is left as it is used, which makes it difficult to use, and it deforms in appearance, resulting in poor appearance. In addition, the metal tube cannot be stood up and must be capped one by one to prevent the contents from leaking out when it is laid down during use.
It feels complicated. In addition, when the content is small, the metal tube is small and difficult to handle.

In order to solve these problems, for example, as disclosed in Japanese Utility Model Publication No. 58-8682 and Japanese Utility Model Publication No. 62-44914, a cylindrical elastic tube or a tubular plastic is provided on the outer circumference of the metal tube. It is proposed to be fitted. However, this method restores the metal tube by the elastic restoring force of the elastic tube or the tubular plastic, and as a result, sucks the discharged matter accumulated at the outlet, so that the restoring ability of the metal tube is not sufficient, The suction power to suck things is weak. In particular, there is a problem that the restoring force becomes weaker as it is used, and the purpose cannot be sufficiently achieved.

As a result of earnest research, the present inventors have found, as a low-viscosity liquid composite container that solves this problem, an inner container having a main body for storing the contents and an opening for discharging the contents from the main body, the inside. An invention has been invented that includes an outer container for covering the main body of the container and a pressure medium interposed between the inner container and the outer container (Japanese Patent Application No. 4-198963). According to this prior invention, the restoring force of the outer container is reliably transmitted to the inner container by the pressure medium, and the restoring property of the inner container is sufficiently enhanced,
It is possible to reliably prevent the liquid from dripping and to discharge the contents to the end.

[0006]

By the way, in the composite container for low-viscosity liquid according to this prior invention, a nozzle is screwed onto the mouth of the inner container, and a lid for closing the discharge port of the nozzle is screwed onto the nozzle. When configured to fit, the lid is strongly screwed, the lid is adhered to the nozzle by the discharged material that has flown down onto the outer peripheral surface of the nozzle, or the discharged material that has flowed down onto the outer peripheral surface of the nozzle is hardened and the nozzle If a bulge is formed on the outer peripheral surface, the nozzle may be screwed together with the lid when the lid is removed, and the nozzle may be unwound from the mouth of the inner container.

The present invention has been made in consideration of the above circumstances, and prevents the lid body from being strongly screwed to a certain value or more, and the nozzle is rotated around when the lid body is unscrewed. An object of the present invention is to provide a composite container for low-viscosity liquid capable of preventing the above-mentioned problems.

[0008]

SUMMARY OF THE INVENTION The present invention is an inner container having a main body for storing contents and a mouth portion for discharging the contents from the main body and screwed to a nozzle, and an outer container for covering the main body of the inner container. In a low-viscosity liquid composite container including a nozzle screwed to the mouth, and a lid that closes a discharge port of the nozzle, in order to achieve the above object, the outer container has a base end of the mouth. A boss that is inserted and has ratchet teeth formed on its outer peripheral surface is provided, while ratchet internal teeth corresponding to the ratchet teeth are provided on the nozzle.

[0009]

When the nozzle is screwed into the mouth of the inner container and the lid is screwed into the nozzle and rotated in the screwing direction, a force acts to rotate the nozzle further in the screwing direction. When the tightening force exceeds a certain value, the ratchet inner teeth slide against the ratchet teeth to idle the nozzle with respect to the boss, and the lid is prevented from being tightened with a force of a certain value or more. Further, after that, when the lid body is unscrewed, the ratchet teeth mesh with the ratchet inner teeth, the rotation of the nozzle in the screwing direction is restrained, and only the lid body is screwed in the unscrewing direction.

The present invention is preferably used in a composite container provided with a pressure medium interposed between an inner container and an outer container, but the present invention is not limited to this because of the above configuration. Therefore, the present invention also includes the following modifications in which the inner container and the outer container are integrally formed, or one of them is omitted and the present invention is applied to one main body container.

That is, a main body container having a main body for accommodating contents and a mouth portion for ejecting the contents from the main body and screwed to the nozzle, a nozzle screwed to the mouth portion, and screwed to the nozzle. In a low-viscosity liquid composite container including a lid for closing the discharge port of the nozzle, a boss having ratchet teeth formed on the outer peripheral surface is provided at the base end of the mouth of the main body container, while the ratchet is provided on the nozzle. It is characterized in that ratchet internal teeth corresponding to the teeth are provided.

Although the following description of the embodiments describes a composite container having an inner container and an outer container, this also applies to the above-mentioned modification.

[0013]

For example, as a material forming the inner container 1 containing an instant adhesive such as α-cyanoacrylate, a metal such as aluminum or lead suitable for containing moisture-curable or solvent-volatile content, or a metal thereof is used. For example, a composite material obtained by laminating and a synthetic resin is used.

A screw 8 for screwing the nozzle 4 is formed on the outer peripheral surface of the tip portion of the mouth portion 7 of the inner container 1. The mouth 9 formed at the tip of the mouth portion 7 is a nozzle before use. It is closed by the thin film 10 that is ruptured by the rupture portion 25 of No. 4. Further, the bottom part is closed by folding back after filling the contents. The outer container 2 is not particularly limited in shape as long as it can hold the pressure medium 3 around the inner container 1, and has a cross-sectional shape such as a cylindrical shape, an elliptical shape, a triangular shape, a polygonal shape such as a square shape, or the like. It can be formed in an arbitrary shape such as a cylindrical shape having a uniform diameter or different diameters, a box shape, a jujube shape, a gourd shape.

In this embodiment, as shown in the side view of FIG. 3, the front elevational view of FIG. 4 and the plan view of FIG. 5, the mantle container 2 is provided in order to improve the handling and enhance the appearance. The outer shape is a tapered cylindrical shape with a gentle top, and the front and rear surfaces are planarly scraped off from the upper end portion to form an elliptic cylindrical shape at the bottom. Further, in this embodiment, the bottom end surface of the outer container 2 is formed into a flat surface so that the composite container can be placed upright.

The outer container 2 may be formed integrally, but in this embodiment, as shown in FIG. 1, it is divided into a main member 11 and a bottom member 12, and the main member 11 is pushed from the outside. It is made of synthetic resin that is easily elastically deformed by pressure. Typical examples of this kind of synthetic resin include polyethylene, polypropylene, polyester, polyamide, polyvinyl chloride, and polybutadiene. Among these, it is recommended to use polybutadiene which is particularly excellent in resilience.

Retaining wall 14 and boss 15 with ratchet teeth formed on the outer peripheral surface
And a positioning protrusion 16, the peripheral wall 13 surrounds the entire main body 6 of the inner container 1 and the base end of the mouth portion 7, and the peripheral wall 13 extends so as to cover the boss 15. The protective cover 100 is formed to enhance the appearance. The receiving wall 14 is formed inside the upper portion of the peripheral wall 13, and the boss 15 is formed continuously on the upper side of the inner peripheral portion of the receiving wall 14. Further, as shown in FIG. 5, ratchet teeth 17 are formed on the outer peripheral surface of the boss 15.

Further, the positioning projections 16 are projected inward at two locations on the major axis of the inner peripheral surface of the bottom of the main member 11, which are opposed to each other. The shape of these positioning protrusions 16 is not particularly limited, but here, as shown in FIG. 4, the amount of protrusion is gradually reduced from the bottom of the main member 11 to the upper side, and the inner circumference of the bottom of the main member 11 is increased at the upper end. It is formed in a shape that is smoothly continuous with the surface.

As shown in FIG. 1, in this embodiment, the inner container 1 is inserted from the bottom side of the outer container 2 from the mouth portion 7 side, and is inserted into an insertion hole 18 extending through the receiving wall 14 and the boss 15. Mouth 7
After being inserted, the pressure medium 3 is filled between the inner container 1 and the outer container 2, and the bottom member 12 is fitted into the bottom portion of the main member 11. The pressure medium 3 is a liquid as long as it can transmit the pressing force applied to the outer container 2 to the inner container 1 and can be deformed in response to the deformation of the inner container 1 and the outer container 2. Alternatively, it may be an elastic body or a viscoelastic body intermediate between the liquid and the elastic body.

Further, in the present invention, in order to enhance the efficiency of pressure transmission, it is advantageous to use, as the pressure medium 3, a material having adhesiveness or adhesiveness to one or both of the inner container 1 and the outer container 2. Is. As the liquid constituting the pressure medium 3, low-viscosity liquids such as water and oil, polyethylene glycol, silicone oil, paraffin, liquid rubber (liquid BR, liquid SBR, liquid NBR, etc.), liquid polybutadiene, liquid polychloroprene, Examples thereof include high viscosity liquids such as liquid polysulfide, liquid polyisoprene, and liquid butyl rubber.

As the viscoelastic body, a so-called gel-like material in which a colloid is solidified is typical, and gelatin, low molecular weight polyethylene, glue and the like can be mentioned as examples. Typical examples of the elastic body include foam, sealing agent, rubber-like elastic body, elastic synthetic resin, elastic adhesive and the like. Examples of this type of foam include urethane foam, expanded polystyrene, expanded polyethylene, expanded polypropylene, and the like.

Examples of the sealing agent include one-component silicone and one-component urethane. Further, the rubber-like elastic body includes natural rubber and synthetic rubber, and among the synthetic rubbers, BR, SBR, NBR, IR,
In addition to EPDM, urethane rubber, silicone rubber, acrylic rubber, ethylene acrylic rubber, polyether rubber, propylene oxide rubber, and various elastomers are included.

Examples of various elastomers include styrene-based thermoplastic elastomers, olefin-based thermoplastic elastomers, urethane-based thermoplastic elastomers, polyester-based thermoplastic elastomers, polyamide-based thermoplastic elastomers, polybutadiene-based thermoplastic elastomers, and vinyl chloride-based thermoplastic elastomers. Examples thereof include a plastic elastomer and a fluorinated thermoplastic elastomer.

As the synthetic resin having elasticity, polyethylene, polypropylene, polyvinyl chloride, polystyrene, polyvinylidene chloride, fluororesin, polymethylmethacrylate, polyamide such as nylon, polyester,
Thermoplastic resins such as polycarbonate, polyphenylene oxide, polyurethane, polyacetal and the like,
As the elastic adhesive, ethylene-vinyl acetate (EVA) hot melt adhesive, thermoplastic rubber hot melt adhesive, polyamide hot melt adhesive, polyester hot melt adhesive, thermosetting hot melt Hot melt adhesives such as adhesives are mentioned as examples.

In this embodiment, a rubber-like elastic body is adopted from these materials. This is because the rubber-like elastic body is prepared by injecting a precursor one-liquid type or two-liquid type liquid composition between the inner container 1 and the outer container 2, and the bottom member 12 is used to open the bottom opening of the main member 11. After the blockage, by performing a curing treatment, the pressure medium 3 made of a rubber-like elastic body can be filled between the inner container 1 and the outer container 2 without a gap, and the manufacturing process can be simplified. This is because it is advantageous in that the pressure medium 3 can be brought into close contact with the inner container 1 and the outer container 2 to enhance the pressure transmission capability.

The material of the bottom member 12 is not particularly limited,
It is preferable to use a material having adhesiveness or adhesiveness to the pressure medium 3, for example, polystyrene, olefin resin, urethane resin, polyester, polyamide,
Thermosetting resins such as polybutadiene, polyvinyl chloride and fluororesins are used. As shown in the plan view of FIG. 6, the front view of FIG. 7, and the side view of FIG.
It has an elliptical bottom wall 12-1 and a pair of spacers 19 standing in line-symmetrical positions with respect to the major axis of the bottom wall 12-1 to the bottom wall 12-1. The outer envelope surface 21 of each spacer 19 is inscribed in the inner peripheral surface of the main member 11, and a positioning groove 22 into which the bottom portion of the inner container 1 and the positioning protrusion 16 are fitted is formed between both spacers 19.

The positioning groove 22 is formed in a V shape having a gentle slope on the tip (upper end) side and a steep slope on the base end side. When the bottom member 12 is fitted into the main member 11, the positioning projection 16 is positioned by the positioning groove 22.
Of the bottom member 12 so that the long axis direction of the bottom member 12 coincides with the long axis direction of the main member 11.
While the bottom portion of the inner container 1 inserted in the main member 11 is fitted into the positioning groove 22,
Positioned between 16. Thus, the folded-back portion (200 in FIG. 1) of the inner container filled with the contents is securely fixed to the central portion of the outer container, and functions to enhance the pressure transmission ability.

The surface of the spacer 19 may be formed as a smooth surface without irregularities, but in this embodiment, the pressure medium 3 is used.
In order to increase the adhesion area or the adhesion area with respect to the concave and convex surfaces, a large number of concave grooves 20 are formed. In this embodiment, since the inner surface of the positioning protrusion 16 is formed so as to smoothly connect to the inner peripheral surface of the peripheral wall 13 at the upper end, the folded-back portion of the bottom portion of the inner container 1 is formed in the major axis direction of the main member 11. When positioning between the positioning protrusions 16 while guiding the spacer 19 to rotate in a direction different from that of the positioning protrusion 16, the folded-back portion of the bottom portion of the inner container 1 can be smoothly mounted on the positioning protrusions 16 with little resistance. Assembly workability can be improved.

Further, in this embodiment, since the upper part of the outer envelope surface 21 of each spacer 19 is inclined inward, the bottom member 12 can be easily fitted into the main member 11, so that the outer container 2 is assembled. Workability is even higher. Figure 9
As shown in the partially cut front view of FIG. 10 and the bottom view of FIG. 10, the nozzle 4 includes a nozzle body 23, a connecting portion 24, and a breaking portion 25, and the connecting portion 24 has a large diameter on the lower side. It is formed in a stepped cylindrical shape, and a female screw 27 corresponding to the screw 8 formed in the mouth portion 7 of the inner container 1 is formed on the inner peripheral surface of the small diameter portion 26, and the large diameter portion is formed.
On the inner peripheral surface of 28, ratchet inner teeth 29 corresponding to the ratchet teeth 17 of the outer container 2 are formed.

The nozzle main body 23 is provided so as to project upward from the upper end wall 30 of the small diameter portion 26, and the peripheral surface thereof is formed as a taper gentle taper peripheral surface. Further, the breakage portion 25 is provided so as to project downward from the upper end wall 30 of the small diameter portion 26, and the peripheral surface thereof is formed into a tapered peripheral surface. Then, a right circular hole shaped discharge passage 31 is penetrated from the lower end of the breakage portion 25 to the upper end of the nozzle body 23.

On the peripheral wall of the large diameter portion 28, a slit 32 cut from the outer peripheral surface to the inner peripheral surface of the large diameter portion 28 and cut over the entire height of the large diameter portion 28 is suitable in the circumferential direction. It is formed at four places spaced apart. Small diameter part 26
A screw for screwing the cap 5 on the outer peripheral surface of the
33 is formed, and an engaging piece 47 that engages with a thread discontinuity groove portion 46 of a screw 37 of a cap 5 described later is bulged between the large diameter portion 28 and the lower end of any of the two threads 33. , The stopper piece 48 for preventing the cap 5 from being screwed into the nozzle 4 too much is bulged slightly apart from the end of the screw 33. At the outer peripheral portion of the upper end wall 30, a liquid breakwater for preventing the discharged material flowing down along the outer peripheral surface of the nozzle body 23 from being transmitted to the outer peripheral surface of the small diameter portion 26.
34 is projected over the entire circumference.

The cap 5 has a hemispherical head portion 35 and an upper tapered taper skirt portion 36 which is continuous with the peripheral portion of the head portion 35, as shown in the front view of FIG. A screw 37 corresponding to the screw 33 of the nozzle 4 is provided on the inner peripheral surface of the lower portion of the portion 36.
Is formed. A screw interruption groove portion 46 for receiving the engagement piece 47 of the nozzle 4 is provided near each lower end of the two threads 37, and the cap 5 is easily screwed by engaging the thread interruption groove portion 46 and the engagement piece 47. Do not understand, the sealing part of the cap 5
Prevent the discharged material from flowing down between the 38 and the opening of the discharge passage 31. Further, a sealing portion 38 is formed on the lower surface of the hemispherical head 35 so as to abut the upper end of the nozzle 4 in the skirt portion 36 and seal the discharge passage 31 when the cap 5 is sufficiently screwed to the nozzle 4. It

The cap 5 between the sealing portion 38 and the screw 37
Liquid dripping preventing folds 39 are formed on the inner peripheral surface of the above in a multi-step manner up and down to above the sealing portion 38. As shown in the enlarged cross-sectional view of FIG. 12, each fold 39 has a right-angled triangle or an acute-angled triangle whose lower surface descends and inclines toward the inner peripheral surface of the cap 5 so as to flow downward. Each discharge has a fold
It is designed so that it can be stored in the form of drops on the inner peripheral edge of 39.

Further, on the inner peripheral surface of the cap 5, there is formed a limiting portion 40 which is received by the outer peripheral surface of the liquid dam 34 of the nozzle 4 when the cap 5 is screwed to the nozzle 4 to a predetermined depth. . When the cap 5 is screwed onto the nozzle 4 and the cap 4 is screwed onto the nozzle 4 to a predetermined depth, the limiting portion 40
Is received by the outer peripheral surface of the liquid breakwater 34 of the nozzle 4, and the screwing of the cap 4 into the nozzle 4 is restricted. In this manner, with the cap 5 screwed to the nozzle 4 to a predetermined depth, the female screw 27 of the nozzle 4 is screwed into the screw 8 formed in the mouth portion 7 of the inner container 1 and screwed in. The rupture portion 25 rushes into the mouth 9 of the inner container 1 to break the thin film 10, the inside of the inner container 1 and the discharge passage 31 of the nozzle 4 communicate with each other, and the rupture portion 25 of the nozzle 4 becomes the mouth of the inner container 1. The nozzle 4 is received by the portion 7 to limit screwing of the nozzle 4 into the inner container 1, and the nozzle 4 and the mouth portion 7 of the inner container 1 are sealed.

When the cap 5 is further screwed, the ratchet inner teeth 29 hit the ratchet teeth 17 and are pushed out in the outer peripheral direction. When the large diameter portion 28 of the nozzle 4 is continuous in the circumferential direction, unless the large diameter portion 28 is extended in the circumferential direction against the elasticity of the large diameter portion 28 of the nozzle 4, the ratchet internal teeth 29 are moved in the outer circumferential direction. Although it cannot be extruded, in this embodiment, the large diameter portion
Since the slit 32 formed by cutting from the outer peripheral surface to the inner peripheral surface of 28 and the entire height of the large diameter portion 28 is formed, the large diameter portion 28 is easily expanded in diameter and the ratchet internal teeth 29 Can be extruded in the outer peripheral direction. Therefore, by screwing the cap 5 with a relatively weaker force than a certain value, the ratchet inner teeth 29 are pushed out in the outer peripheral direction to get over the ratchet teeth 17, and the nozzle 4 and the cap 5 idle around the outer container 2, 5 is prevented from being tightened into the nozzle 4 with a force of a certain level or more.

After that, when the cap 5 is rotated in the screwing direction, the ratchet inner teeth 29 are locked to the ratchet teeth 17, so that the nozzle 4 can rotate in the screwing direction with respect to the outer container 2. It is possible to reliably prevent the nozzle 4 from turning around with the cap 5 and being unwound from the inner container 1,
Only cap 5 can be securely removed. When the peripheral wall 13 of the envelope 2 is pressed with fingers with the cap 5 removed,
The peripheral wall 13 of the outer container 2 is dented, the pressing force is transmitted to the main body 6 of the inner container 1 via the pressure medium 3, the inner container 1 is dented, and the contents are discharged to the outside via the discharge passage 31 of the nozzle 4. To be done.

A part of the discharged substance adheres to the tip of the nozzle body 23, but when the force for pressing the outer container 2 is removed, the outer container 2 and the pressure medium 3 elastically restore, and accordingly, the inner container. The shape of No. 1 is restored, and most of the discharged matter attached to the tip of the nozzle body 23 is sucked back into the discharge passage 31 or the inside container 1, whereby liquid sagging hardly occurs.

For some reason, the discharge material attached to the outer peripheral surface of the tip of the nozzle body 23 is discharged through the discharge passage 31 or the inner container 1.
It is difficult to be sucked back in, and may flow down to the connecting portion 24 along the outer peripheral surface of the nozzle body 23. However, the connection
Discharged material that has flowed down to 24 is the base end of the nozzle body 23 and the liquid breakwater.
It is stored in the annular space formed between 34 and the connection part.
It does not flow down to the outer surface of 23. As a result, it is possible to reliably prevent the discharge substance from adhering to the screw 33 of the nozzle 4 and hindering the screwing of the cap 5 into the nozzle 4 or adhering the nozzle 4 and the cap 5 screwed thereto. Therefore, the operability of the screwdriver of the cap 5 is enhanced.

When the cap 5 is screwed on after use, the tip of the nozzle body 23 comes into contact with the inner peripheral surface of the cap 5,
Although a small amount of the ejected substance may adhere to the inner peripheral surface of the cap 5 from the tip of the nozzle body 23, the ejected substance adheres to the inner peripheral surface of the cap 5 and tends to flow down along the inner peripheral surface of the cap 5. Things are caught in the folds 39 to prevent dripping and
It will not run down to 37. Therefore, it is possible to reliably prevent the discharged material from adhering to the screw 37 of the cap 5 and solidifying to hinder the screwing of the cap 5 or adhering the nozzle 4 and the cap 5 screwed thereto. Therefore, the operability of the screwdriver of the cap 5 can be improved.

As described above, according to the low viscosity liquid composite container of the present invention, the boss in which the base end of the mouth is fitted in the outer container and the ratchet teeth are formed on the outer peripheral surface thereof. On the other hand, by providing the ratchet inner teeth corresponding to the ratchet teeth to the nozzle screwed to the mouth of the inner container, the nozzle is idled in the screwing direction and screwed to the mouth of the inner container, It is possible to prevent the lid that is screwed to the screw from being tightened into the nozzle with a certain force or more, and it is possible to reliably prevent the screw of the cap and the screw of the corresponding nozzle from being damaged. When doing so, it is possible to reliably prevent the nozzle from turning around with the lid and being unwound from the inner container, and to improve usability.

In the present invention, particularly when a slit is formed in the portion of the nozzle where the ratchet inner tooth is formed, which divides the portion in the circumferential direction, the ratchet tooth is attached to the ratchet inner tooth with a relatively weak screwing force. It is possible to allow the vehicle to pass over and idle, and it is possible to more reliably prevent the screw of the cap and the screw of the nozzle corresponding thereto from being damaged by screwing the cap too much.
