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.

In a low-viscosity liquid composite container in which a metal tube is used as a main body container, a nozzle is attached to the mouth of the main body container, and a lid for closing the discharge port of the nozzle is provided, the adhesive which is the content is used. After discharging, so-called liquid sagging occurs. This phenomenon becomes more remarkable when the content has a low viscosity such as an instant adhesive.

[0004]

By the way, according to the present invention,
In a low-viscosity liquid composite container in which a nozzle is attached to the mouth of the main body container and a lid for closing the discharge port of the nozzle by, for example, screwing is provided, when the lid is screwed into the nozzle after use, the nozzle is The tip of the lid contacts the inner surface of the lid, and the discharge material remaining on the tip of the nozzle adheres to the inner surface of the lid, resulting in a narrow gap between the lid and the nozzle. May fall into the joint. Since the fitting part of the lid to the nozzle is formed with screws, fitting surface, etc. that are in close contact with the nozzle,
The discharged discharge product is blocked and accumulated at the fitting portion and solidifies to adhere the lid and the nozzle to each other, or to generate resistance against removal of the lid.

The present invention has been made in consideration of the above circumstances, and when the lid is mounted, the discharge material attached to the inner peripheral surface of the lid does not flow down to the fitting portion of the lid to the nozzle. An object of the present invention is to provide a composite container for low viscosity liquid which can be prevented.

[0006]

According to the present invention, there is provided a main body container having a main body for accommodating contents and a mouth portion for ejecting the contents from the main body, a nozzle communicating with the mouth portion, and a nozzle outlet. In order to achieve the above object, the following measures are taken on the premise of a low-viscosity liquid composite container having a closing lid.

That is, a feature is that a dripping preventing fold is formed on the inner peripheral surface of the portion of the lid body above the nozzle fitting portion. Further, it is characterized in that when the lid is attached to the nozzle, a protruding sealing portion is formed on the lower surface of the head of the lid to abut the upper end of the nozzle to seal the discharge passage.

Disappear. In the present invention, the cross-sectional shape of the fold is not particularly limited, but in order to prevent discharge from flowing down the lower surface of the fold and to facilitate removal of the inner mold of the lid during molding of the lid, the lower surface of the fold is described. Is preferably formed horizontally or on an inwardly inclined surface.

Further, in the present invention, there is a limit to the amount of the discharge product that can be captured by one fold, and the area where the discharge product adheres is not always constant. Therefore, it is desired to increase the amount of the discharge product that can be captured by one fold and to expand the region where the discharge of the discharge product can be prevented. In order to meet this demand, the inner peripheral surface of the upper portion of the lid fitted to the nozzle is provided with a spiral fold that is swung many times over a predetermined range in the vertical direction, or the lid is fitted to the nozzle. It is possible to meet the above-mentioned demand by providing a large number of annular pleats continuous in a predetermined range in the vertical direction on the inner peripheral surface of the portion above the mating portion in the vertical direction, and the latter is particularly advantageous.

After inserting the mouth portion 7 into the opening 18, the pressure medium 3 is filled between the inner container 1 and the outer container 2, and thereafter, 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.

In this embodiment, the pressure medium 3 is made of a rubber-like elastic material from these materials. The reason for this is that 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 opening the bottom surface of the main member 11 by the bottom member 12. After closing, the pressure medium 3 made of a rubber-like elastic material can be filled between the inner container 1 and the outer container 2 by a curing process, 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, but 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, polybutadiene. Thermosetting resins such as polyvinyl chloride and fluororesins are used. This bottom member 12 is shown in FIG.
As shown in the plan view of FIG. 7, the front view of FIG. 7, and the side view of FIG. 8, the elliptical bottom wall 12-1 and the bottom wall 12-1 are placed in line symmetrical positions with respect to the long axis of the bottom wall 12-1.

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, and when the bottom member 12 is fitted into the main member 11, the positioning projection 16 is positioned.
The bottom member is guided by the side surface of 22 and fits in between them, so that the long axis direction of the bottom member 12 coincides with the long axis direction of the main member 11.
While the 12 is positioned, the bottom of the inner container 1 inserted into the main member 11 is fitted into the positioning groove 22 and positioned between the positioning protrusions 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.

When positioning the folded-back portion of the bottom of the inner container 1, the bottom of the inner container 1 is guided by the spacer 19 from a direction different from the major axis direction of the main member 11 and is positioned between the positioning protrusions 16 while rotating. It At this time, both ends of the bottom of the inner container 1 may be caught by the positioning protrusions 16 and impair the assembly workability. However, in this embodiment, the upper ends of the positioning protrusions 16 are smoothly connected to the inner peripheral surface of the peripheral wall 13. Since it is formed, the folded-back portion of the bottom portion of the inner container 1 is smoothly placed on the positioning protrusion 16 with little resistance, and the assembling workability is not impaired.

Further, in this embodiment, by inclining the upper part of the outer envelope surface 21 of each spacer 19 inward, the bottom member 12 can be easily fitted into the main member 11 and the outer container 2
The assembly workability of is further improved. The surface of the spacer 19 may be formed as a smooth surface without unevenness, but in this embodiment, in order to increase the adhesive area or adhesive area to the pressure medium 3, a large number of concave grooves 20 are formed on the surface.
It is formed on the uneven surface on which is formed.

As shown in the partial front view of FIG. 9 and the bottom view of FIG. 10, the nozzle 4 includes a nozzle body 23 and a connecting portion 24.
And a breaking portion 25, the connecting portion 24 is formed in a stepped cylindrical shape having a large diameter on the lower side, and a screw formed in the opening portion 7 of the inner container 1 on the inner peripheral surface of the small diameter portion 26. 8 is formed, and ratchet inner teeth 29 corresponding to the ratchet teeth 17 of the outer container 2 are formed on the inner peripheral surface of the large diameter portion 28.

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 is cut from the outer peripheral surface to the inner peripheral surface of the large-diameter portion 28, and is cut over the entire height of the large-diameter portion 28 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 the cap 5 described below 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 that has flowed 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 interrupted 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 screw interrupted 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, on the lower surface of the hemispherical head portion 35, when the cap 5 is sufficiently screwed to the nozzle 4, a protruding sealing portion that abuts the upper end of the nozzle 4 in the skirt portion 36 and seals the discharge passage 31.
38 is formed.

This sealing portion is formed so as to project inside the cap 5, and the void portion 50 is provided around the sealing portion, so that it is possible to catch the discharged extra discharged substance, which is convenient. On the inner peripheral surface of the cap 5 between the sealing portion 38 and the screw portion 37, liquid dripping preventing folds 39 are formed in a vertically multi-stage up to the upper portion of the sealing portion 38. The cross-sectional shape of each pleat 39 facilitates the die-cutting of the inside of the cap 5 when the cap 5 is molded, and makes it difficult for discharged substances to flow down the underside of the pleat 39, so as shown in the enlarged cross-sectional view of FIG. In addition, the lower surface is formed into a horizontal shape or a triangular shape having an inwardly inclined surface.

The inner peripheral surface of the cap 5 has a nozzle 4 when the cap 5 is screwed to the nozzle 4 to a predetermined depth.
A limiting portion 40 is formed on the outer peripheral surface of the liquid levee 34. When this 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 on the outer peripheral surface of the liquid bank 34 of the nozzle 4, and the nozzle 4
The screwing of the cap 4 onto the 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. Break

The broken portion 25 is received by the mouth portion 7 of the inner container 1 to restrict 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.

Further, when the cap 5 is screwed in the screwing direction, 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, the large diameter portion 28 must be extended in the circumferential direction against the elasticity of the large diameter portion 28 of the nozzle 4, so the cap 5 and the If the nozzle 4 is not identified, the ratchet internal teeth 29 cannot be pushed out in the outer peripheral direction, and the nozzle 4 cannot be screwed in. However, in this embodiment, since the slit 32 that is cut from the outer peripheral surface to the inner peripheral surface of the large diameter portion 28 and is cut across the entire height of the large diameter portion 28 is formed, a weak rotational force is given. The large diameter portion 28 can be easily expanded by simply pushing out the ratchet inner teeth 29 in the outer peripheral direction to idle the nozzle 4 and the cap 5 with respect to the outer container 2, and the cap 5 can be operated with a certain force or more. It is possible to prevent the nozzle 4 from being tightened.

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. When the force for pressing the outer container 2 is removed, the outer container 2 and the pressure medium 3 are elastically restored, and along with this, 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.

It is difficult for the discharge material attached to the outer peripheral surface of the tip portion of the nozzle body 23 during use to be sucked back into the discharge passage 31 or the inner container 1, and to flow down to the connecting portion 24 along the outer peripheral surface of the nozzle body 23. There is. However, the discharged substance that has flown down to the connecting portion 24 is stored in an annular space formed between the base end portion of the nozzle body 23 and the liquid breakwater 34, and does not flow down to the outer peripheral surface of the connecting portion 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,
The discharged matter may adhere to the inner peripheral surface of the cap 5 from the tip portion of the nozzle body 23. However, the discharged matter that adheres to the inner peripheral surface of the cap 5 and tends to flow down along the inner peripheral surface of the cap 5 is Droplets are caught in the folds 39 to prevent dripping,
It does not run down to screw 37. Therefore, it is possible to surely prevent the discharged material from adhering to the screw 37 of the cap 5 and solidifying to prevent 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.
