Description

  The present invention relates to an apparatus for removing a sealing ring remaining on the neck of a bottle such as a wine bottle.

  As a lid device made of a metal plate for sealing a bottle, there is a type in which a sealing ring for ensuring virginity is integrated with a screw lid. That is, as shown in FIG. 10, a sealing ring 2 is integrally provided at the lower end of the screw lid 1, and both are connected by a bridge group 6 at a location of a flange 5 provided on an elongated neck 4 of the bottle 3. ing.

  A packing (not shown) is arranged on the inner surface of the top of the screw lid 1, and after filling the bottle 3 with the contents, the packing is crushed and the screw lid 1 is pressed from above. The bottle 3 is sealed by rolling the facing screw thread 8 and rolling the inward protrusion 9 directly below the flange 5. The neck 4 of the bottle 3 is generally tapered downward, and the lower end of the sealing ring 2 is in contact with or close to the outer periphery of the neck 4.

  When the screw lid 1 is unscrewed, the bridge portion 6 is broken and opened, but the sealing ring 2 remains on the neck portion 4 of the bottle 3, which causes a problem that the bottle 3 is recycled. That is, since the materials of the bottle 3 and the sealing ring 2 are different, the sealing ring 2 and the bottle 3 must be separated for recycling them, but the waste is discarded as the separation is troublesome. There was a case, and as a result, the recycling of the bottle 3 and the sealing ring 2 (particularly the recycling of the bottle 3) was insufficient.

  On the other hand, there are types of pill fur proof caps made of resin, but the pill fur proof ring remains on the neck of the bottle. However, since the material of the bottle and pill fur proof ring (or pill fur proof band) is different, recycling (especially When recycling bottles, the pilfer proof ring must be removed from the bottle.

  Therefore, a removal tool for pilfer proof rings has been proposed. As an example, Patent Document 1 discloses a push-down cutter device. In other words, the cutter device of Patent Document 1 is such that a cutter is planted inside a bottomed cylindrical cutter cover that fits into the mouth of a bottle from above, and when the cutter cover is pushed down by covering the mouth of the bottle, the cutter The pilfer proof ring (end ring) is cut.

Japanese Patent Publication No. 2013-159399

  The pill fur proof ring of the resin pill fur proof cap is located above the flange provided on the neck of the bottle (more precisely, between the flanges adjacent to each other vertically). When the cutter is pressed against the pilfer proof ring supported from below by the flange, the pilfer proof ring is pushed out and becomes non-looped.

  On the other hand, as shown in FIG. 10, in the metal (aluminum) screw cap 1 for wine bottle, the sealing ring 2 extends long below the flange 5, so that the cutter is integrated with the cutter cover as in Patent Document 1. If it is only provided, the sealing ring 2 cannot be cut due to insufficient stroke. That is, the thing of patent document 1 cannot be applied to the removal of the long metal sealing ring 2.

  The present invention has been made to improve such a current situation, and an object of the present invention is to provide an apparatus that can be easily removed even with a sealing ring having a long length.

The present invention is a device used to remove a sealing ring left on the neck of a bottle, which device is as claimed in claim 1,
"It has a regulating body that hits the top surface of the mouth of the bottle from above, and a pusher that is attached to the regulating body in a state where it can be pushed down against a spring,
While the regulating body is provided with a positioning part that fits into the mouth of the bottle from the inside or from the outside or both inside and outside,
The pusher has a cylinder part that surrounds the bottle from the outside, and a bottom part provided at an upper end of the cylinder part, and the sealing ring is moved to the inner side surrounded by the cylinder part by a push-down movement of the pusher. A cutter that cuts the bottle in the axial direction of the bottle is provided. ''
It is the composition. The pusher can also be called a slider or a movable body.

  The bottle is used in an upward position so that the contents do not spill. That is, the upward posture can be said to be the reference posture of the bottle. Therefore, in the present invention, the configuration is specified in a state where it is used for a bottle in an upward posture. However, this identification method is for easy understanding of the configuration, and does not exclude use in a posture in which the bottle is turned sideways or use in a posture in which the bottle is turned down.

The present invention can be developed in various ways. Examples of the development are given in claims 2 to 4 .

In the example of Claim 2 , the said cutter is pushed with the elastic body in the direction which the front-end | tip contact | abuts or adjoins to the outer peripheral surface of the neck part in the said bottle .

The example of claim 3 relates to a safety device. That is, in Claim 3, in Claim 1 or 2, the lock member which hold | maintains so that the said pusher cannot descend | fall unless the said regulation body is inserted in the said bottle is provided .

Claim 4 is also obtained by applying the safety device (locking member). That is, the lock this in claim 4, in any of the preceding claims, in which the inside of the front Symbol pusher, said not fit the regulating body in the mouth of the bottle pusher is held so that it can not be lowered In a state where the member is arranged in the circumferential direction away from the cutter and the restricting body is not fitted into the mouth of the bottle, the pusher cannot be pushed down by stretching the lock body against the restricting body. When the restricting body is fitted into the mouth of the bottle, the lock body escapes from the restricting body and the pusher is allowed to be pushed down .

  In the present invention, for example, when a regulating body is fitted from above into a mouth of a bottle placed in an upward posture and the pusher is pushed down, the sealing ring is cut (cut) by the cutter provided in the pusher. In this case, since the stroke of the pusher can be set arbitrarily, even a sealing ring having a long length can be cut without any problem. Moreover, since the position of the pusher is accurately maintained by positioning the regulating body, the sealing ring can be accurately cut while suppressing the deviation of the cutter.

Moreover, in this invention, since a pusher is hold | maintained in the stable attitude | position which does not slip laterally by having a cylinder part, there exists an advantage which can cut | disconnect a sealing ring more reliably. Moreover, since the cutter is hidden inside the pusher, there is an advantage that safety can be improved.

If the tip of the cutter hits the outer periphery of the sealing ring, there is a concern that the sealing ring will not be cut or the cutting will be insufficient even if the pusher is pushed down. By adopting this point, Claim 2 , since the tip of the cutter abuts or approaches the outer peripheral surface of the neck of the bottle, the tip (lower end) of the cutter can be reliably applied to the upper end surface of the sealing ring. Cutting of the sealing ring can be further ensured.

The sealing ring removing device of the present invention has no safety problem if it is properly managed and used properly, but for some reason, the pusher and the regulating body are moved relative to each other without being used in the bottle. It cannot be said that there will be no situation where the fingertip touches the cutter. In this respect, if the development examples of claims 3 and 4 are adopted, the pusher cannot be pushed and moved unless used in a bottle, which is an advantage of ensuring high safety.

(1) Structure of First Embodiment Next, an embodiment of the present invention will be described with reference to the drawings. First, the structure of the first embodiment shown in FIGS . 1 to 5 will be described. The sealing ring removing device includes a resin (or metal) regulating body 11 that abuts on the top surface 7 of the bottle 3 and a pusher 12 that is fitted to the neck 4 of the bottle 3 from the outside.

  The pusher 12 includes a cylindrical portion 13 and a bottom portion 14 fitted thereto, and a regulating body 11 is slidably fitted on a rod 15 fixed to the bottom portion 14 by screwing. In other words, the pusher 12 is slidably attached to the regulating body 11 via the rod 15. The outer periphery of the cylinder part 13 and the outer periphery of the bottom part 14 are the same diameter (same outer peripheral surface).

  The cylindrical portion 13 and the bottom portion 14 of the pusher 12 may be made of resin or metal such as aluminum die cast. When the cylindrical portion 13 is made of resin, it can be transparent or translucent. The tube portion 13 and the bottom portion 14 can be integrated by screwing.

The rod 15 is fitted with a spring 16 that urges the regulating body 11 in a direction away from the bottom 14 of the pusher 12. In this case, the bottom portion 14 is provided with a recess 17 having a depth that can accommodate the spring 16 so that the restricting body 11 can move until it comes into contact with the bottom portion 14.

  The restricting body 11 is integrally provided with a boss portion 18 that enters the mouth portion of the bottle 3 as a positioning means for holding itself in the mouth portion 5 of the bottle 2 so as not to be laterally displaced, and the rod 15 also slides on the boss portion 18. Fits freely. A disc-shaped stopper plate 19 is fixed to the front end surface (lower end surface) of the rod 15 with a screw 20 so as to prevent the restriction body 11 from coming off by contacting the front end surface of the boss 18.

  As the retaining means, without using the stopper plate 19, a screw 20 having a large-diameter flanged head may be used (that is, the head of the screw 20 can be used for retaining). is there.). It is also possible to integrally provide a rod (or flange) for retaining the rod 14 integrally.

  The regulating body 11 is integrally provided with an outer cylinder portion 21 that surrounds the mouth portion of the bottle 3 from the outside. The positioning of the regulating body 11 can be performed only by the boss portion 18 or only by the outer cylinder portion 21. When the outer cylinder part 21 is provided, since the vertical length of the restricting body 11 is increased, there is an advantage that the slide of the pusher 12 becomes smooth.

  The sealing ring removing device includes a metal cutter 22 that cuts the sealing ring 2 in the axial direction of the bottle 3. The cutter 22 has a rod-like (prism-like) shape that is long in the axial direction of the rod 15, and is arranged in a posture substantially along the inner peripheral surface of the cylindrical portion 13 of the pusher 12.

  As shown in FIGS. 1B and 2, the bottom portion 14 of the pusher 12 is formed with a concave groove 23 into which the upper end portion (one end portion) of the cutter 22 is inserted. It is connected to the bottom part 14 by a pin 24 in a posture perpendicular to the bottom part 14. Further, a rubber 25 that urges (presses) the cutter 22 outwardly is disposed in the groove 23 a provided in the concave groove 23 on the upper end side of the pin 24 as an example of an elastic body. Note that a spring such as a coil spring or a leaf spring may be used instead of the rubber 25.

  The lower end portion (tip portion / other end portion) of the cutter 22 is a beak portion 22 a that is bent so as to enter the notch groove 26 formed in the regulating body 11. The beak portion 22a becomes thinner toward the tip, and a ridge line-shaped cutting blade 27 extending in the axial direction of the rod 15 is formed on the opposite side of the beak portion 22a from the rod 15. The cutting blade 27 is inclined with respect to the axial center of the rod 15 in a side view as viewed from the axial direction of the pin 24. Further, as shown in FIG. 1D, a triangular inward end surface 28 that faces the outer peripheral surface of the neck 4 of the bottle 3 is formed at the tip of the beak portion 22a.

  At least the beak portion 22a of the cutter 22 is quenched. On the other hand, the cutting blade portion may be made of special steel or a carbide material and fixed to the main body of the cutter 22 by brazing. In this case, steel (steel) which is not quenched is used for the main body of the cutter 22. It is also possible to adopt a cartridge system in which the beak portion 22a can be replaced. Moreover, since the tip of the cutter 22 is hidden inside the pusher 12, safety is high.

(2). Summary of First Embodiment As shown in FIG. 3, the tip of the cutter 22 is positioned at the upper end of the flange 5 in the bottle 3 with the restricting body 11 just touching the top surface 7 of the bottle 3. It is set to do. Since the neck portion 4 of the bottle 3 is tapered downward, the lower end of the sealing ring 2 is in contact with the neck portion 4, and thus the sealing ring 2 is held so as not to move down.

  Therefore, when a person pushes down the pusher 12 with his / her hand on the top surface 7 of the bottle 3, the sealing ring 2 is moved vertically (bottle by the cutting blade 27 of the cutter 22 as shown in FIG. 4). When the pusher 12 is pushed down, the cutting blade 27 of the cutter 22 is detached from the lower end of the sealing ring 2 and the sealing ring 2 is non-looped as shown in FIG. Cut into shapes.

  Therefore, the sealing ring 2 can be unfolded and removed from the neck 4 of the bottle 3 as shown by a one-dot chain line in FIG. A pair of cutters 22 can be provided on both sides of the rod 15, and in this case, the sealing ring 2 is divided into two as shown in FIG. Accordingly, the sealing ring 2 is detached from the neck portion 4 of the bottle 3 simultaneously with the cutting. In this case, there is no need to bend the sealing ring 2 one by one.

  When the beak portion 22 a is provided in the cutter 22 as in the present embodiment, the cutting blade 27 can be accurately applied to the sealing ring 2 while the main body portion of the cutter 22 is brought close to the inner peripheral surface of the cylindrical portion 13. Further, when the rubber 25 as the elastic body is provided, the cutting blade 27 of the cutter 22 can be brought into contact with or close to the outer peripheral surface of the neck portion 4 in the bottle 3, so that the cutting blade 27 is securely attached to the upper end surface of the sealing ring 2. Can bite into. Therefore, the cutting of the sealing ring 2 can be ensured.

  Further, as in the embodiment, when the inward end surface 28 facing the outer peripheral surface of the bottle 3 is formed at the tip of the cutter 22, the inward end surface 28 can come into surface contact with the outer peripheral surface of the neck 4 in the bottle 3. 22 guides are performed smoothly.

  When the cutting blade 27 bites into the sealing ring 2, the sealing ring 2 is pulled toward the cutting blade 27, so that a gap between the sealing ring 2 and the outer peripheral surface of the neck portion 4 increases at the cutting blade 27. . For this reason, the cutting edge 27 bites into the sealing ring 2 more reliably. Further, when the cutting blade 27 is inclined with respect to the axial center of the rod 15 as in the embodiment, since the slender action of the sealing ring 2 by the cutting blade 27 is ensured, there is an advantage that the sealing ring 2 can be smoothly opened. is there.

  Now, the bottle 3 is manufactured by the blow molding method, and air is blown into the parison from the nozzle 29 using the nozzle 29 that fits in the mouth as shown by a one-dot chain line in FIG. In this case, since the parison is pressed against the inner surface of the mold by the pressure of air, the mouth portion often has higher dimensional accuracy of the outer diameter than that of the inner diameter.

  Therefore, as in the present embodiment, when the outer cylinder portion 21 that is fitted from the outside to the mouth portion of the bottle 3 is provided as the positioning means of the restricting body 11, there is an advantage that the sealing ring removing device can be accurately positioned. Of course, only the boss portion 18 may be used as the positioning means, or the boss portion 18 and the outer cylinder portion 21 may be used in combination as in the present embodiment. If both are used in combination, it can be said that it is suitable because it is regulated from inside and outside.

The device of the embodiment can be held with one hand. Therefore, it is conceivable that a person holds the pusher 12 with one hand and tries to push the regulating body 11 with the fingertip of the other hand for some reason. In this case, since the fingertip of a person does not hit only the restricting body 11 and usually hits the stopper plate 19 and the screw 20, the restricting body 11 is not pushed into the pusher 12. Therefore, the fingertip does not touch the tip of the cutter 22 and is excellent in safety.

(3). Second Embodiment Next, a second embodiment shown in FIGS. This embodiment is basically the same as the first embodiment, and the main difference from the first embodiment is that a lock member 31 as a safety device is provided. Therefore, members common to the first embodiment are denoted by the same reference numerals, and description thereof is omitted unless necessary.

  In the present embodiment, a vertically long lock member 31 that functions as a safety device is disposed in a portion of the pusher 12 opposite to the cutter 22 across the axis. The lock member 31 has a square cross section and is approximately the same length as the cutter 22. The upper end of the lock member 31 is connected to the pusher 12 by a pin 32 so that the lower end moves far and away from the axis of the pusher 12. For this reason, a concave groove 33 into which the upper portion of the lock member 31 is fitted is formed in the bottom portion 14 constituting the pusher 12.

  A rubber 34 that pushes the lock member 31 to the outside of the shaft center is disposed at a position above the pin 32 in the concave groove 33 into which the lock member 31 is fitted. The rubber 34 is fitted in the slot 35 and is held so as not to fall off. Further, the lock member 31 is formed with an upper recess 36 into which the rubber 34 is fitted. The rubber 34 is an example of elastic means, and the lock member 31 is urged by the rubber 34 so that the lower end thereof is directed toward the axial center of the pusher 12.

The lower end portion of the lock member 31 is fitted in a notch groove 37 formed in the restricting body 11 with play. A lower concave portion 39 that opens toward the axial center of the pusher 12 is formed at the lower end portion of the lock member 31, and the upper end portion of the lower concave portion 39 forms a lower corner portion (stopper receiving portion) 38 of the notch groove 37. It is the stopper part 40 which hits from the top. The stopper portion 40 is slightly inclined so as to go radially outward from the top to the bottom, but may be perpendicular to the inner surface of the lock member 31.

A connecting portion between the lower end surface and the inner surface of the lock member 31 is a lower inclined surface 41 cut obliquely. Moreover, the lower end of the lower recessed part 39 is also the intermediate inclined surface 42 which goes to an axial center toward the bottom from the top. In this embodiment, a socket bolt is used for the rod 15. The head of the bolt enters a counterbore hole 18 a provided in the boss portion 18 of the regulating body 11.

  The tip of the cutter 22 enters the pusher 12 by a certain size. Therefore, even if a person puts a fingertip on the opening edge of the pusher 12, there is no injury. For example, even if a person pushes only the restriction body 11 with a finger for some reason, the restriction body 11 cannot be moved by being held by the lock member 31. For this reason, a finger | toe of a person does not touch the front-end | tip part of the cutter 22, and higher safety | security can be ensured.

  On the other hand, as shown in FIG. 8, when the pusher 12 is fitted into the mouth of the bottle 3, the inclined guide surface 41 at the lower end of the lock member 31 hits the outer peripheral edge of the upper end of the mouth of the bottle 3. Then, due to the guide action of the lower slope 41, the lock member 31 rotates so that the lower end thereof is away from the axis of the pusher 12. Thereby, the lock by the lock member 31 is automatically released, the pusher 12 is allowed to be pushed down, and the sealing ring 2 is torn by the cutter 22.

When the pusher 12 is pushed down, the lower end of the lock member 31 hits the screw thread 43 of the bottle 3, but the lower inclined surface 41 of the lock member 31 also serves as a guide for getting over the screw thread 44 of the bottle 3. Further, when sealing ring 2 is returned by pusher 12 spring 16 is disconnected, the intermediate inclined surface 42 of the lower end of the lower recess 30 of the locking member 31 hits the thread 43 of the bottle 3, the inclination of the intermediate inclined surface 42 Then, the lock member 31 escapes and rotates, and the pusher 12 returns smoothly and moves.

  Also in this embodiment, the cutter 22 includes the beak portion 22a as in the first embodiment. However, this embodiment does not include the inward end surface 28 provided in the first embodiment, and the inner surface of the beak portion 22a in this embodiment sandwiches an intermediate surface 44 substantially parallel to the axis of the pusher 12. In this embodiment, inclined surfaces 45 and 46 are formed vertically. Therefore, an acute angle point is formed by the lower inclined surface 46 and the cutting edge 27. In the present embodiment, the upper end of the cutting blade 27 extends to the vicinity of the inner surface of the pusher 12. Therefore, the cutting edge 27 of this embodiment is considerably longer than that of the first embodiment. The cylindrical portion 13 is fixed to the bottom portion 14 with a pin 49 (the same applies to the first embodiment).

  In the present embodiment, a recess 47 into which the rubber 25 is fitted is formed at the upper end of the cutter 22. In the embodiment, one lock member 31 is used, but a plurality of lock members 31 may be attached. It is also possible to arrange a pair of cutters 22 on both sides with the axis of the pusher 12 in between, and to arrange the lock members 31 respectively at portions between the adjacent cutters 22.

(4). Third Embodiment Next, a third embodiment shown in FIG. 9 will be described. This embodiment is another example of the safety device (locking means), and the structure excluding the safety device is the same as that of the second embodiment. In this embodiment, the lock member 50 has an L-shaped configuration in which an inward horizontal portion and a downward portion are connected to each other, and is disposed at a portion opposite to the cutter 22 with the axial center of the pusher 12 interposed therebetween.

  The lock member 50 is fitted into a housing hole 51 of an outward opening provided in the restricting body 11 so as to move freely in the radial direction of the pusher 12 by a small size. The tip of the inwardly horizontal portion of the lock member 50 is a stopper portion 52, and the rod 15 is formed with an annular groove 53 as a stopper receiving portion into which the stopper portion 52 of the lock member 50 is fitted and removed. Has been. Therefore, in a state where the stopper portion 52 is fitted in the annular groove 53 of the rod 15, the regulating body 11 and the pusher 12 are held so as not to be relatively movable, and when the stopper portion 52 is separated from the annular groove 53 of the rod 15, Relative movement between the regulating body 11 and the pusher 12 is allowed.

  The lock member 50 is urged inward (in a locked posture) by the leaf spring 54. The leaf spring 54 is fixed to a receiving seat 55 provided in the storage hole 51 with a screw 56. The receiving seat 55 is located below the restricting body 11, and the leaf spring 54 extends obliquely inward from the receiving seat 55, and the tip is in contact with the lock member 50.

  The storage hole 51 is also opened on the inner side of the outer cylinder portion 21 in the restricting body 11, and the downward portion of the lock member 50 is partially exposed in the annular groove inside the outer cylinder portion 21. And the inclination guide surface 57 which the top surface outer periphery of the opening part of the bottle 3 contacts is formed in the lower end of the downward part in the locking member 50. FIG. The inclined guide surface 57 is inclined so as to shift outward in the radial direction as it goes downward.

  In this embodiment, in the state where the pusher 12 is retracted by the spring 16, as described above, the stopper portion 52 of the lock member 50 is fitted in the annular groove 53 of the rod 15 even if the regulating body 11 is pushed with the fingertip. Therefore, the regulating body 11 cannot be pushed in. Accordingly, it is possible to ensure high safety by preventing the fingertip from touching the tip of the cutter 22.

  On the other hand, when the restricting body 11 is fitted into the mouth of the bottle 3, the lock member 50 moves away from the rod 15 by the guiding action of the inclined guide surface 57. Then, the stopper portion 52 of the lock member 50 is detached from the annular groove 53 of the rod 15. That is, the lock is released. Accordingly, the pusher 12 is allowed to be pushed down. As an urging means for the lock member 50, a coil spring, rubber, or the like can be used.

(5). Others The present invention can be embodied in various ways other than the above embodiment. For example, the pusher 12 is not limited to the two-part method of the cylindrical portion 13 and the bottom portion 14, but may be an integral structure (however, the two-part method is preferable from the viewpoint of ease of attachment of the cutter 22. ).

  Moreover, as a positioning means of the regulation body 11, you may provide the cylinder part which fits into the opening | mouth part of the bottle 3 from the outside. When the cylindrical portion 13 is provided on the pusher 12 as in each embodiment, the cutter 22 can be attached to the cylindrical portion 13. The locking member need not be pivotable as in the embodiment. The lock member can also be provided on the restricting body.

  The present invention can be actually manufactured and practically used. Therefore, it can be used industrially.
