Description

When opening a sealed carbon dioxide foaming beverage container, the present invention can operate a composite cap composed of a cap and a cap lid to pull out a hat-type plug stopper fitted to the container. The present invention also relates to a structure for sealing a carbon dioxide gas-foamable beverage container with a plug stopper and a composite cap, and a method of opening the plug stopper that protrudes from the container opening due to gas pressure inside the container and is housed inside the composite cap.

As a typical first method for sealing a carbon dioxide foaming beverage container, there is a method for sealing a carbonated soft drink container made of synthetic resin. This method is a sealing method using a composite container lid composed of a synthetic resin inner stopper fitted and fixed to the container mouth, and a synthetic resin upper lid that covers the inner stopper and is fastened to a screw on the outer surface of the container. Yes, when opening the screw, it is possible to recognize that the tamper evidence band has been cut off and the seal has not been released by loosening the screw on the composite container lid, and if the screw is further loosened, a seal break will occur before the screw is released. The gas inside the container gradually escapes and opens. Patent Document 1 includes a composite container lid constituted by a synthetic resin inner stopper fitted and fixed to such a container mouth and a synthetic resin upper lid screwed to the container so as to cover the inner stopper. The sealing method is shown.

Further, as a typical second method for sealing a carbon dioxide foaming beverage container, there is a sealing method for sparkling wine or the like. In this method, the plug body is pressed and inserted into the bottle mouth, and then fixed with a metal wire fastener to prevent the plug body from coming off and sealed, or further, provided in the pressed and inserted plug body. There is a sealing method that adds a mechanism that prevents the stopper from coming off even if the clasp is removed when the stopper is removed so that the protrusion and the protrusion provided on the upper part of the bottle are engaged. Patent Document 2 discloses a sealing structure composed of such an inner plug and a clasp.

In the second method, when opening the stopper, remove the clasp, pull out the stopper from the bottle mouth, and in the final stage of opening, hold the stopper in the state of popping out of the mouth by the gas pressure inside the container, When the force is released, the plug body will move away from the bottle and jump out of the bottle mouth, and at that moment, a “pong” sound will be necessary. In addition, the plug body that has jumped out from the bottle mouth is received with a hand or cloth to prevent the plug body from jumping into the space.

Synthetic resin composite container lid with excellent impact properties Sealing structure for sparkling beverage bottle containing carbon dioxide

However, although it is inferior in gas permeability and heat resistance compared to glass containers, it has advantages in terms of mass productivity, economy, and transportation, and the range of use as a container for soft drinks and alcoholic beverages has expanded. The first method of sealing carbonated beverage containers made of synthetic resin is that when the screw is loosened, the tamper evidence band is cut off when the screw is loosened, and a seal break occurs from a slight gap that occurs before the screw is released. Because the carbon dioxide inside the container gradually escapes, the stopper does not pop out of the container, and while safe, it does not emit the "pong" sound that is required when opening sparkling wine. Not suitable for wine containers.

In addition, in the second method in which the container is press-fitted into a glass bottle and fixed with a clasp or the like and sealed, the clasp is removed when the stopper is opened, and the bottle is firmly grasped by hand. Gradually lift up to the mouth, hold the hand from the bottle mouth to the stage where the stopper body pops out due to gas pressure inside the container, release the force and the stopper body will pop out from the bottle mouth and make a “pong” sound. The stopper is received by covering the bottle mouth with a hand or cloth different from the hand holding the stopper to prevent the stopper from jumping into the space. However, if you catch the plug that has popped out of the bottle mouth with your hand, you will feel pain in your hand, or the plug will jump out into the space due to failure to receive it, leading to accidents such as colliding with people around you or lighting equipment etc. As a countermeasure, the method is to cover the bottle mouth with a cloth and open it. However, it is only performed in a part, and the sound of “pong” is blocked by the cloth and becomes small. Therefore, further improvement is required.

The carbon dioxide-containing sparkling beverage container according to the present invention has a sealing structure in which a synthetic resin container is sealed with a synthetic resin plug stopper and a synthetic resin composite cap. When the hat-type plug stopper is press-fitted, the upper annular protrusion on the outer surface of the upper part of the plug stopper engages with the lower part of the bead at the upper part of the container mouth, the plug stopper seals the container, and the composite cap is screwed onto the container. In the sealing structure that can prevent the plug stopper from coming off, the plug stopper forms a toothed tooth on the inner side of the upper end, and the composite cap is lowered from the inner surface of the cap and the dome-shaped top portion with a screw to form a cylindrical wall. The cap opening portion is formed by a cap lid formed of an arm and a claw, and the plug opening portion is inserted inside the hat-type plug plug when sealing.

The upper annular protrusion on the upper outer surface of the plug stopper and the lower annular protrusion on the lower outer surface are formed at a predetermined distance.

Further, when the plug is sealed, the hook formed on the inner surface of the upper end of the plug plug and the hook of the lower end of the plug removal portion of the composite cap are located at a predetermined distance in the vertical direction, and the tip of the inward toothed hook Is characterized in that there is a gap with the outer surface of the cylindrical wall of the plug opening portion, and the tip of the outward claws has a gap with the inner surface of the plug plug sealing cylindrical portion. In the process of pulling out the surface, the surface with which the toothed teeth and the claws engage is inclined at a predetermined angle.

Therefore, according to the present invention, when opening the plug, the composite cap is twisted in the loosening direction to release the threaded engagement between the container and the composite cap, the composite cap is lifted to a predetermined height, and the bottom end of the unplugged portion of the composite cap The cap hook is engaged with the hook teeth on the upper part of the plug stopper, and the composite cap is lifted up with moderate force, or the plug stopper is pulled out by rolling, and the lower annular protrusion of the plug stopper engages with the container mouth bead. When the container is lifted up to the height, the plug stopper is locked and once removed, the plug stopper is stopped.

When the lower annular protrusion of the plug stopper is engaged with the container mouth bead and stopped from being pulled out, a force is applied to lift the composite cap again and the container mouth bead is moved over. The stopper is characterized in that it is popped out from the container mouth by the gas pressure inside the container and is opened.

Furthermore, simultaneously with the plug stopper popping out, the compressed gas in the container expands instantaneously and is released at once into a space free of obstacles generated between the container mouth and the bottom surface of the plug stopper.

The plug stopper that has jumped out of the container instantaneously contacts the top of the composite cap and is stored inside the composite cap, so that the plug stopper does not protrude into the space around the container.

According to the present invention, when a plug stopper is press-fitted into a container filled with carbonated drink, which is the first stage of sealing, in a sealing method using a synthetic resin carbonated beverage container, a plug stopper, and a composite cap, The bead prevents the plug cap from coming off by locking the upper annular projection on the outside of the plug plug sealing cylinder, and in the second stage of the plug, the composite cap is screwed into the container to plug the plug cap. Can be removed without touching the plug cap by twisting, lifting, or twisting the composite cap with one hand. In addition, a plug structure is provided in which the plug stopper that protrudes vigorously from the container mouth due to the gas pressure inside the container contacts the inner surface of the top of the composite cap and fits inside the composite cap at the final stage of opening. Is done.

According to the present invention described above, in the opening operation of a carbonated beverage container made of synthetic resin, the gripped composite cap is twisted and lifted without touching the hat-type plug stopper press-fitted into the container. The plug stopper that can be opened by the squeezing action and that pops out of the container mouth by the gas pressure inside the container at the final stage of opening is always inside the composite cap, and there is a danger of jumping out into the space around the container. Absent.

At the same time as the plug stopper pops out of the container mouth, the compressed gas in the container expands all at once, generating a “pong” sound that is necessary for opening the sparkling wine.

Containers and stoppers are used in large quantities in soft drinks, alcoholic beverages, etc., and can be made of low-cost, synthetic resin that has established mass-production technology and recycling systems. Seals are pressed into containers. Carbonated beverage containers such as soft drinks, alcoholic beverages, and sparkling wines that can be reliably sealed by pressing the plug cap with the composite cap and that the seal is not released by the tamper evidence band when opening the plug. The sealing structure is obtained.

The container and the container sealing structure according to the present invention can also be applied to a glass container that is superior in heat resistance and gas permeability as compared with a plastic container.

FIG. 1 shows a state in which a plug stopper 1 is press-fitted into a container 5, and the outer diameter of the sealing cylindrical portion 10 of the plug stopper 1 is before being press-fitted into the container 5. Is slightly larger than the inner diameter of the container mouth, can be press-fitted into the container 5 containing carbonated beverages to seal the container 5, and the container mouth 50 is formed with a bead 51 bulging inside, When the plug 51 is press-fitted, the bead 51 engages with the upper annular protrusion 13 on the outer top of the plug plug 1 to lock the plug plug 1 and prevent the plug plug 1 from being pulled out by the gas pressure inside the container. ing. Further, the lower annular protrusion 14 firmly presses a part of the plug stopper 1 against the inner surface of the container to ensure the sealing. Further, the pressure applied to the container 5 when the plug stopper 1 is press-fitted can be received by the pressure receiving flange 54, and the container body below the pressure receiving flange 54 does not require strength to withstand the pressure during the press-fitting.

In addition, as shown in FIG. 2, the composite cap A that reliably prevents the plug stopper 1 from coming out of the container is composed of a cap lid 2 and a cap 3, and the outer peripheral projection 21 of the dome-shaped cap lid 2 is The composite cap A is configured by being fitted and fixed to an annular claw 33 provided on the upper surface of the upper plate 32. In addition, the cap 3 which is a part to be gripped when performing the opening operation has a screw 31 to be screwed into the container 5 and has a slightly flattened shape with an oval shape in the middle of the outer surface. Anti-slip when gripping the indentations in a ring shape, and a tamper evidence band 4 is connected to the lower end via a bridge 40. Further, the cap lid 2 forms a stopper part 20 downward from the inner surface of the dome-shaped top part, and the stopper part 20 is a cylindrical part 22 at the top, and there are a plurality of gaps in the vertical direction in the cylindrical wall below it. The columnar arms 23 provided at intervals are arranged in a ring shape, and a claw 24 is formed outward of the lower end of the arm 23.

The method of attaching the composite cap A to the top of the container 5 into which the plug stopper 1 has been press-fitted will be described with reference to FIG. 3. When the composite cap A is put on the top of the container 5, the inclined surface of the claw 24 at the lower end of the stopper opening 20 is plugged. When the composite cap A is further pushed into contact with the inclined surface of the toothed hook 12 at the upper end of the stopper 1, the claws 24 slide on the inclined surface of the toothed tooth 12, and at the same time, the arms 23 arranged in an annular shape with a gap therebetween are formed. The inner claw 24 is elastically bent inward, the tip claw 24 is moved inward, and the opening of the toothed hook 12 is inserted, and the plug removal portion 20 is inserted into the plug plug 1 so that the curve of the arm 23 is restored.

When the composite cap A is further pushed in, the screw 31 of the cap 3 comes into contact with the screw 52 of the container 5, and when the cap 3 is turned in the fastening direction to complete the screwing, the tamper evident band 4 is locked in a predetermined position. FIG. 4 shows a state where the sealing is completed.

When opening the cap, holding the composite cap A with one hand and turning the screw in the opening direction, the cap 3 is lifted up, and the flap piece 41 of the tamper-evident band 4 contacts the lower side of the thick portion 53 of the container 5, The rise of the tamper evident band 4 is restricted, and the desired opening history clarification function is achieved by the bridge 40 breaking and being detached from the cap 3.

The composite cap A separated from the tamper evident band 4 is further swiveled to release the screw, and the composite cap A is lifted until the claw 24 of the plug opening 20 contacts the tooth 12 on the top of the plug 1, and When the composite cap A is lifted and lifted, the upper annular protrusion 13 of the plug stopper 1 passes over the bead 51 of the container 5 and the engagement between the container 5 and the plug stopper 1 is once released, and the plug stopper 1 and the container 5 are On the contact surface, the force that tries to stop the plug stopper 1 by the friction force generated when the sealing cylindrical portion 10 presses against the inner surface of the container, and the force that tries to push the plug stopper 1 out of the container 5 by the gas pressure inside the container. When the composite cap A is lifted from there, the plug stopper 1 is relatively easily lifted until the lower annular projection 14 comes into contact with the bead 51 of the container 5, and then the plug stopper 1 is locked. FIG. 5 shows the state in which it comes off. In this locked state, the lower end of the lifted cap 3 is at the same or higher position than the top of the container 5.

When the composite cap A is lifted and lifted again from the state shown in FIG. 5, the lower annular protrusion 14 of the plug stopper 1 gets over the bead 51, and the plug stopper 1 jumps out of the container mouth by the gas pressure inside the container. FIG. 6 shows a state in which 1 moves instantaneously and contacts the inner surface of the top of the cap lid 2. At the same time as the plug stopper 1 jumps out of the container port 50, the compressed gas in the container expands at a stretch and emits a “pong” sound.

Further, as shown in FIG. 6, since the plug opening 20 of the composite cap A is inserted inside the hat-type plug 1, the plug 1 that has jumped out of the container is stored inside the composite cap A, and the surrounding space. Plug plug 1 will not pop out.

The sealing structure and opening method of a carbonated beverage container described in the present invention has a gas permeability smaller than that of a synthetic resin container, excellent heat resistance, and can be reused. FIG. 7 shows a sealing structure of a glass container.

In FIG. 7, the glass container bottle 7 is formed with a screw 70, a thick part 71, and a bead 72 as in the case of the container 5, and the outer diameter of the sealed cylindrical part 10 of the plug stopper 1 before press-fitting is as follows. The bottle 7 containing the carbonated beverage can be sealed by press-fitting the plug stopper 1 so as to be slightly larger than the inner diameter of the container opening of the bottle 7. In addition, a bead 72 swelled inward is formed at the container mouth of the bottle 7, and when the plug stopper 1 is press-fitted, it engages with the upper annular protrusion 13 on the outside of the plug stopper 1 to engage the plug stopper 1. The stopper 1 prevents the plug stopper 1 from being pulled out by the gas pressure inside the container, and the lower annular protrusion 14 presses a part of the plug stopper 1 more strongly against the inner surface of the container to make the stopper of the bottle 7 more reliable. Yes.

The composite cap B that prevents the plug stopper 1 from coming out of the bottle 7 includes a metal cap 6 that can be easily processed according to the strength of the glass of the bottle 7 and the screw shape dimensions, and a lower side from the inner surface of the dome-shaped top. The cap lid 2 that forms the stopper part 20 is fitted and fixed by the fitting part 60, and the cylindrical body part of the metal cap 6 is perforated at a predetermined height to the circumference. The rupture part 62 is provided to form a pill fuffproof cap. Further, the upper part of the bottle opener 20 is a cylindrical part 22, and the lower part of the stopper part 20 is a cylindrical wall with a plurality of gaps provided at equal intervals in the vertical direction and arranged in a ring shape, and a claw 24 is provided at the lower end of the arm 23. Is provided.

The method of attaching the composite cap B to the bottle 7 into which the plug stopper 1 is press-fitted is that the metal cap 6 of the composite cap B has a cylindrical body, and the inner diameter of the body is slightly smaller than the screw 70 and the thick part 71 of the bottle 7. Largely, when the composite cap B is put on the bottle 7 into which the plug stopper 1 is press-fitted, the inclined surface of the claw 24 at the lower end of the stopper portion 20 comes into contact with the inclined surface of the upper stopper tooth 12 of the plug stopper. When pushed in, the claw 24 slides on the inclined surface of the toothed teeth 12, and at the same time, the arms 23 arranged in a ring with a gap between each other are elastically bent inward, and the claw 24 at the tip of the arm 23 is moved inward to move the claw The opening of the tooth 12 is inserted, and the plug opening 20 is inserted into the plug plug 1 so that the curvature of the arm 23 is restored. Further, in a state where the metal cap 6 is in pressure contact with the upper portion of the plug stopper 1, a plastic screw 61 is formed by matching the body portion of the metal cap 6 with the shape of the screw 70 of the bottle 7, and similarly, the lower end of the metal cap 6 is The sealing is completed by drawing in accordance with the shape of the lower end of the thick portion 71 of the bottle 7.

When opening the metal cap 6, the composite cap B is lifted when the screw is swung in the direction of loosening, and the lower part of the metal cap 6 is cut off at the perforation of the cutting part 62, and the desired opening history is clearly indicated as a pill fuffproof cap.

Further, in the same manner as described in FIG. 5, the composite cap B is further rotated to release the screw, and the composite cap B is brought into contact with the toothed teeth 12 on the top of the plug stopper 1 by the claw 24 of the plug opening 20. When the composite cap B is lifted up until it comes into contact, the upper annular projection 13 of the plug stopper 1 passes over the bead 72 of the bottle and the bottle 7 and the plug stopper 1 are disengaged once. At the surface where the bottle 7 comes into contact, the sealing cylinder portion 10 tries to push the plug stopper 1 out of the bottle 7 by the force to stop the plug stopper 1 by the frictional force generated by the pressure contact with the inner surface of the container and the gas pressure inside the container. When the composite cap B is lifted from this state, the plug cap 1 is lifted relatively easily until the lower annular protrusion 14 comes into contact with the bead 72 of the bottle 7, and when it comes into contact, the plug plug 1 Stops and stops. In this locked state, the lower end of the raised metal cap 6 is at the same or higher position than the top of the bottle 7.

When the plug cap 1 in the state shown in FIG. 5 is again lifted by holding the composite cap B in the same manner as described in FIG. 6, and the lower annular protrusion 14 gets over the bead 72, the plug cap 1 is A state is shown in which the plug stopper 1 that has popped out from the container opening 50 vigorously by the gas pressure inside the container of the bottle 7 is in contact with the top inner surface of the cap lid 2. At the same time as the plug stopper pops out from the container port 50, the compressed gas in the container expands at a stretch and emits a “pong” sound.

Further, since the plug opening 20 of the composite cap B is inserted inside the hat-type plug 1, the plug 1 that has jumped out of the container is housed in the composite cap B, and the plug 1 jumps out into the surrounding space. There is nothing.
