Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a high-viscosity liquid filling container in which a high-viscosity liquid such as a sealing material or an adhesive for construction is injected into a container body and stoppered.

[0002]

[Prior art]

 As a sealing material filling container filled with a sealing material for building, as shown in a filling container 100 shown in FIG. 9, a discharge port 102 for discharging a sealing material 101 is formed at a distal end portion, and a hard base having a base end portion opened. A container having a cylindrical main body 103 and a plunger 104 fitted inside the base opening of the main body 103 is widely used. In the filling container 100, a sealing lid 105 for sealing the discharge port 102 is opened, and then the virgin film 106 is cut. Then, a nozzle (not shown) is attached to the discharge port 102, and this is connected to a dedicated discharge gun. The sealing material 101 can be extruded and ejected by sequentially moving the plunger 104 toward the inner end of the container body 103 by operating the lever of the ejection gun.

By the way, as a method for filling this kind of container body 103 with the sealing material 101, the container body 103 is usually held in a vertical position with the base end thereof facing upward. A certain amount of the sealing material 101 is filled so as to prevent air bubbles from entering the container. A method of forcibly discharging the sliding portion to the outside and inserting the sealing material 101 so that air does not remain therein is adopted.

In the filling container 100 having such a configuration, the air between the plunger 104 and the sealing material 101 can be almost completely discharged to the outside, and the airtightness between the plunger 104 and the container body 103 is also improved. It is widely used at present because it can be sufficiently secured. However, since the container main body 103 is hard, the filling container 100 cannot be crushed after use, and there is a limit in volume reduction, and there is a problem that the waste is bulky. was there.

Therefore, as described in Japanese Patent Application Laid-Open No. 7-171461, the intermediate body of the container body is formed of a soft film material, and the relatively hard upper molding portion is formed at the distal end and the base end of the container main body. There has also been proposed a filling container in which a lower molding portion is integrally formed with a filling container. In this filling container, this is loaded into the outer cylinder of the discharge gun and the lower molded part is moved to the upper molded part side, so that the sealing material is extruded from the discharge port formed in the upper molded part while the intermediate body part is crushed. Since the container is discharged, the filled container after use becomes small and crushed, and the volume of waste can be reduced. This publication also discloses a filling method of filling a sealing material into the container body from an opening of a lower molded portion formed in a ring shape, and closing the opening in an airtight manner after the filling. Is described.

[0006]

[Problems to be solved by the invention]

 In the filling container described in the above publication, since the sealing material is discharged while crushing the container body, the volume of the used container can be reduced, but there are the following problems. That is, in order to improve the airtightness between the lower molded portion and the lid member, the lid member and the lower molded portion can be hermetically fixed via, for example, an annular concave-convex fitting portion. With such a configuration, the mounting position of the lid member with respect to the lower molded portion is fixedly set, so if the injection amount of the sealing material into the container body is not accurately set, if the injection amount is small, the sealing material may be inserted into the filling container. If air remains and the sealing material hardens in the filling container and the injection amount is large, a problem occurs in that the sealing material overflows to the outside when the lid member is plugged. Even when the container is filled with high accuracy, it is necessary that the air between the container body and the lid member be completely exhausted when the lid member is fitted in the container body in an airtight manner. It was difficult to fit the lid member so that it did not.

[0007] When the inventor of the present invention sets a relatively large amount of the sealing material into the container body, the excess sealing material overflows to the outside, but the air between the container body and the lid member is almost completely discharged. With the sealing material injected into the container body, the middle part of the sealing material in the length direction is pressed to raise the level of the sealing material liquid level with respect to the container body, and the apparent injection of the sealing material is performed. By setting a large amount, it was found that the air between the container body and the lid member was almost completely exhausted when the lid member was inserted and mounted.

An object of the present invention is to provide a highly viscous liquid filling container that can effectively prevent air from remaining in the filling container and that does not make the used filling container bulky.

[0009]

Means for Solving the Problems and Their Functions

 The highly viscous liquid-filled container according to claim 1 is configured such that the body is formed of a flexible film material, the lower end of the body is closed with a rigid bottom plate member, and the upper end of the body has rigidity. A cylindrical container body with a bottom provided with a reinforcing ring having an opening formed therein, a lid member hermetically fixed to the reinforcing ring of the container body, and a highly viscous liquid filled in the container body. After the high-viscosity liquid is poured into the container body, the body of the container body is pressed down to raise the liquid surface of the high-viscosity liquid, and then the lid member is air-tightly fixed to the reinforcing ring. The container body is filled so that air does not remain.

In this filling container, since the body of the container body is made of a flexible film material, it becomes possible to discharge the high-viscosity liquid from the container body while crushing the body, and to end use. The filled container becomes small and crushed, and the volume of waste can be significantly reduced. In addition, since the body is made of a film material made of a member separate from the reinforcing ring and the bottom plate member, it is possible to use, for example, a laminate of aluminum foil as the film material, which restricts the material of the body. Therefore, the body of the container body can be made of a material that is inexpensive and that can prevent the quality of the highly viscous liquid from deteriorating. Further, the lid member is inserted and fixed to the reinforcing ring provided integrally with the container body, and the positional relationship between the lid member and the reinforcing ring does not change, so that both can be reliably hermetically sealed. Moreover, since the high-viscosity liquid is filled in the container body as described below, air is prevented from remaining between the lid member and the high-viscosity liquid.

First, since the high-viscosity liquid injected into the container body has a high viscosity, the liquid surface has a mountain shape with a bulged central portion. In this state, the body portion of the container body is pressed, When the liquid surface of the viscous liquid is raised, the liquid surface of the high viscous liquid rises while substantially maintaining the mountain shape at the time of injection. That is, by pressing the body, the apparent injection of the high-viscosity liquid injected into the container body is set to be relatively large. Then, when the lid member is inserted into the reinforcing ring of the container body with the liquid surface of the high-viscosity liquid raised as described above, the lid member first comes into close contact with the top of the liquid surface of the high-viscosity liquid, Next, while the top portion of the liquid surface is crushed, the contact portion between the liquid surface and the lid member is expanded toward the outer peripheral side, and the container is inserted into the reinforcing ring while returning the body portion of the container body to the original shape. There is no gap between them, and the air in the container body is almost completely exhausted, and then inserted and fixed to the reinforcing ring in an airtight manner.

A filling container according to a second aspect of the present invention is the filling container according to the first aspect, wherein the lid member is provided with a sliding cylinder portion inserted into a reinforcing ring. With this configuration, it is possible to insert the sliding cylinder into the reinforcing ring while discharging the air in the container body from the gap between the reinforcing ring and the sliding cylinder, and the air remains in the container body. The lid member can be fixed to the reinforcing ring in a gas-tight manner so as not to do so.

A filling container according to a third aspect of the present invention is the filling container according to the second aspect, wherein the lid member is provided with a flange having an annular groove fitted to an upper end of the reinforcing ring. With this configuration, it is possible to further improve the airtightness between the lid member and the reinforcing ring, and to prevent the deterioration and hardening of the high viscosity liquid due to the invasion of outside air from the gap between the lid member and the reinforcing ring. Can be prevented. According to a fourth aspect of the present invention, there is provided the filling container according to the third aspect, wherein the flange and the reinforcing ring are formed with annular concave and convex fitting portions which are fitted to each other in an annular groove. With this configuration, the airtightness between the lid member and the reinforcing ring can be further improved.

According to a fifth aspect of the present invention, there is provided the filling container according to any one of the second to fourth aspects, wherein a lower end is opened in a container main body, and an upper end is opened on an outer surface of the sliding cylinder portion. The sliding cylinder is formed with a gas vent groove extending to near the upper end. In this case, when the lid member is inserted into the reinforcing ring, the air between the lid member and the highly viscous liquid is efficiently discharged from the groove, so that air remaining between the lid member and the highly viscous liquid is reduced. It can be more effectively prevented. The filling container according to claim 6 is the filling container according to any one of claims 1 to 5, wherein a discharge port for a highly viscous liquid is formed in the lid member, and a discharge port is formed on a lower surface of the lid member. A virgin film to be closed is attached. In this case, when the lid member is fitted to the reinforcing ring, it is possible to prevent air from remaining and transmitting at the edge of the discharge port.

[0015]

As the film material constituting the body portion 10, any material can be used as long as it is a flexible material that can be crushed and reduced in volume, and can be made of various materials, and has a single-layer structure or a multi-layer structure made of only a resin film. A film material may be used, or a film material having a multilayer structure in which a metal foil such as an aluminum foil is laminated between resin films may be used. In the present embodiment, a three-layer film material in which aluminum foil is laminated between two resin films is used, and the film material is rolled into a cylindrical shape, and the side edges are overlapped and heat sealed. It is manufactured in a shape. As the material of the resin film, polyethylene, polyester, nylon, polypropylene, and the like can be used. The inner and outer resin films may be made of the same kind of material, but since the use conditions are different between the inner surface and the outer surface, it is preferable to use a resin film made of a material according to the use conditions. . For example, when filling the container body 2 with a sealing material for construction as the highly viscous liquid 4, a film such as polyethylene or polypropylene which does not deteriorate due to contact with the sealing material is used as the resin film on the inner surface side. It is desirable to use a film such as polyester or nylon as the resin film on the outer surface side with emphasis on strength and gas barrier properties.

An annular upright portion 12a extending upward is formed on an outer peripheral portion of the bottom plate member 12, and a lower end portion of the body portion 10 is air-tightly joined to an inner peripheral surface of the upright portion 12a. The lower end is closed by a bottom plate member 12. The upper end of the body portion 10 is superimposed on the inner peripheral surface of the reinforcing ring 11 to a position slightly lower than the upper end of the reinforcing ring 11 and is joined in an airtight manner. A fitting protrusion 14 projecting upward is formed in an annular shape at an upper end portion of the reinforcing ring 11, and a fitting groove 15 is formed on an outer peripheral surface of the fitting protrusion 14. The reinforcing ring 11 and the bottom plate member 12 may be joined to the body 10 by heat sealing or the like. Alternatively, the body 10 may be loaded into an injection molding machine and the reinforcing ring 11 or the bottom plate member 12 may be connected to the body 10. May be integrally formed.

As shown in FIGS. 1 to 4, the lid member 3 includes a sliding cylinder 20 inserted into the reinforcing ring 11, and an inward opening extending from the lower end of the sliding cylinder 20 to open the container body 2. A lid main body 21 for closing the portion 13 and a flange portion 22 extending outward from the upper end portion of the sliding cylinder portion 20 are integrally formed using a synthetic resin material. An annular groove 23 is formed in the flange 22 so as to open downward and externally fits into the fitting projection 14 of the reinforcing ring 11, and projects into the annular groove 23 to fit the reinforcing ring 11. An annular protrusion 24 is formed in the mating groove 15 so as to fit into and out of the groove 15. The sliding member 20 of the cover member 3 is inserted into the reinforcing ring 11, and the fitting projection 14 of the reinforcing ring 11 is fitted into the annular groove 23 of the cover member 3. Further, the protruding portion 24 of the lid member 3 is fitted in the fitting groove 15 of the reinforcing ring 11 and fixed in an airtight manner. However, the annular groove 23 may be filled with an adhesive or an adhesive to improve the sealing property between the lid member 3 and the reinforcing ring 11. Further, lubricating oil or the like may be applied in advance to the outer surface of the sliding cylinder 20 so that the sliding cylinder 20 can be smoothly inserted into the reinforcing ring 11.

A tapered portion 25 whose diameter is reduced downward is formed on the outer peripheral surface of the lower end of the sliding cylindrical portion 20 of the lid member 3, and the lower end is opened in the container body 2 in the middle of the sliding cylindrical portion 20. In addition, gas vent grooves 26 whose upper ends extend to the vicinity of the flange 22 are formed at regular intervals in the circumferential direction. A discharge port 27 is formed in the center of the lid main body 21, and a cylindrical portion 28 that extends upward is formed integrally with the discharge port 27. A virgin film 29 for closing the discharge port 27 is adhered to the bottom surface of the lid main body 21. When the virgin film 29 is used, the virgin film 29 is cut out, and a nozzle (not shown) is attached to the cylindrical portion 28. Will be discharged.

Next, a method for filling the container body 2 with the highly viscous liquid 4 will be described. First, as shown in FIGS. 5A and 5B, a required amount of the high-viscosity liquid 4 is injected into the container body 2 so that air bubbles do not enter the high-viscosity liquid 4. The liquid surface of the high-viscosity liquid 4 has a mountain-like shape with a raised central portion because the viscosity of the high-viscosity liquid 4 is high. Next, as shown in FIG. 5 (c) and FIG. 6, the middle of the body 10 of the container body 2 is pressed to raise the liquid surface of the high-viscosity liquid 4, and the injected high-viscosity liquid 4 Adjust the apparent injection volume slightly. At this time, the liquid surface of the highly viscous liquid 4 rises while substantially maintaining the mountain shape at the time of injection.

Next, as shown in FIG. 5D, the lid member 3 is fitted to the reinforcing ring 11 of the container body 2, and at this time, the lid member 3 is first fitted as shown in FIG. The liquid of the high-viscosity liquid 4 is adhered to the top of the liquid surface of the high-viscosity liquid 4 and then crushed, that is, while the contact portion between the liquid surface and the cover member 3 is widened toward the outer periphery. The air between the cover member 3 and the highly viscous liquid 4 is exhausted because the cover member 3 comes into close contact with the surface. The cover member 3 is inserted into the reinforcing ring 20 as shown in FIG. Since the body 10 is a flexible film without releasing the pressing of the body 10, the lid member 3 may be inserted and plugged with a force larger than the pressing force.

Next, in order to fit the lid member 3 to the reinforcing ring 11 in an airtight manner, the lid member 3 is further strongly pushed into the reinforcing ring 11, and as shown in FIG. The fitting projection 14 of the reinforcing ring 11 is fitted to the fitting ring, and the projection 24 of the lid member 3 is fitted to the fitting groove 15 of the reinforcing ring 11 to fix the lid member 3 to the reinforcing ring 11 in an airtight manner. Will do. In the highly viscous liquid filling container 1 in which the high viscous liquid 4 is filled in the container body 2 as described above, air can be effectively prevented from remaining near the lid member 3, and the high viscous liquid due to the residual air can be effectively prevented. Deterioration and hardening of the liquid 4 can be effectively prevented. In the present embodiment, the present invention is applied to the high viscosity liquid filling container 1 in which the container body 2 is filled with the high viscosity liquid 4 such as a sealing material or an adhesive for building, but may be used for mayonnaise or jam. The present invention can be similarly applied to a filling container filled with a highly viscous liquid other than for construction such as foods. Also, in the case where the opening 13 of the container body 2 is directly sealed with a virgin film instead of the lid member 3, the middle part of the body 10 is pressed down and the inside of the container body 2 is pressed. By attaching the virgin film in a state where the apparent injection amount of the high-viscosity liquid 4 is adjusted to be relatively large, the high-viscosity liquid 4 can be sealed so that air does not remain in the container body 2.

[Effect of the invention]

 According to the highly viscous liquid filling container according to the first aspect, since the body of the container body is made of a flexible film material, the high viscous liquid is discharged from the container body while the body is crushed. Since the used filling container becomes small and crushed, the volume of waste can be greatly reduced. In addition, since the body is made of a film material made of a member separate from the reinforcing ring and the bottom plate member, restrictions on the material are reduced, and the container is made of a material that is inexpensive and can prevent the deterioration of the quality of the high viscosity liquid. The body of the main body can be configured. Further, since the lid member is fixed to a predetermined position of the reinforcing ring and does not move relative to the reinforcing ring, the space between the lid member and the reinforcing ring can be reliably hermetically sealed. In addition, since the lid is fixed to the reinforcing ring with the apparent injection volume of the high-viscosity liquid injected into the container body being adjusted to a relatively large amount, air remains between the lid and the high-viscosity liquid. As a result, quality deterioration and hardening of the highly viscous liquid can be prevented.

According to the second aspect of the present invention, when the lid member is provided with a sliding cylinder inserted into the reinforcing ring, the air in the container body is discharged from the gap between the reinforcing ring and the sliding cylinder. In addition, the sliding cylindrical portion can be inserted into the reinforcing ring, and the lid member can be air-tightly fixed to the reinforcing ring so that air does not remain in the container body. Providing a flange having an annular groove fitted to the upper end of the reinforcing ring on the lid member as described in claim 3 makes it possible to further improve the airtightness between the lid member and the reinforcing ring. In addition, quality deterioration and hardening of the highly viscous liquid due to intrusion of outside air from a gap between the lid member and the reinforcing ring can be prevented.

According to a fourth aspect of the present invention, when the flange portion and the reinforcing ring are formed annularly with the concave / convex fitting portion which is fitted in the annular groove, the airtightness between the lid member and the reinforcing ring is further improved. it can. According to a fifth aspect of the present invention, when a groove for venting gas is formed on the outer surface of the sliding cylinder portion, the lower end of which is opened in the container body and the upper end of the sliding cylinder portion extends to near the upper end. Since the air between the lid member and the high-viscosity liquid is efficiently discharged from the groove when fitting, the residual air between the lid member and the high-viscosity liquid can be more effectively prevented. As described in claim 6, if a high-viscosity liquid discharge port is formed in the lid member and a virgin film that closes the discharge port is attached to the lower surface of the lid member, when the lid member is inserted into the reinforcing ring, Thus, it is possible to prevent air from remaining at the edge of the discharge port.
