Description

  The present invention relates to a composite cap including an inner stopper and a cap, and more particularly to an easily separable composite cap that can be easily detached from a container body that is attached at the time of disposal.

The applicant has already proposed an easily separable composite cap that can be easily separated from the container at the time of disposal and can be easily separated. (For example, see Patent Document 1)

  The composite cap of the above-mentioned Patent Document 1 is fitted with a mounting cylinder on the outer periphery and mounted on the container body, and includes a slip-out preventing means engaged with the mounting cylinder and the mouth-and-neck outer periphery to prevent slipping, and A middle plug with a fitting cylinder upright above the mounting cylinder, and a peripheral wall fitted and locked to the outer periphery of the fitting cylinder so that it can be attached to and detached from the inner plug. The cap peripheral wall lower end edge and the ring upper end edge part are integrally connected via a connecting portion, and the cap peripheral wall lower end edge is in a non-connecting portion other than the connecting portion. And the ring upper end edge are connected by a plurality of easily cutable connecting pieces in the circumferential direction.

And when disposing, after screwing the cap together with the ring, each ring can be easily cut off by pulling the ring with the cap, etc. The cap is rotated again to a position where it can be screwed onto the inner plug. After that, when the cap is screwed to the inner stopper in that state, and then the ring is pulled up from the state, the cap and the inner stopper are screwed together, so that the inner stopper is lifted and removed from the container body. It is configured as follows.
Japanese Patent Application No. 2008-047792

  The composite cap can be easily removed from the container when disposing of the container after use, and can be removed without using a jig when removing the container. There is no fear of loosening and the like, and when removing, it is an excellent one that exhibits an effect such as efficient transmission of force and easy removal.

  The present invention is a further improvement of the above-described composite cap, and it is easier to rotate the ring with respect to the cap while providing sufficient coupling strength between the ring and the cap, and the removal operation of the inner plug can be performed more easily and reliably. A composite cap with easy separation is proposed.

The first means is configured as follows. That is, the mounting cylinder 10 is fitted to the outer periphery of the mouth-and-neck portion 101 to be attached to the container body 100, and provided with a slip-out preventing means that is engaged with the mounting cylinder 10 and the outer periphery of the mouth-and-neck portion 101 while preventing the slipping-out. and the inner plug a was erected fitting tube 13 to the mounting cylinder 10 upwards, together with possible be attached removably to the inside cap a by screwing the peripheral wall 30 to the fitting tube 13 outer circumference, mounted from the peripheral wall 30 the lower edge A cap B having a ring C suspended from the outer periphery of the cylinder 10, and a part of the lower end edge of the cap peripheral wall 30 and a part of the upper end edge of the ring C are integrally connected via a connecting part 40, and a connecting part In the non-connected portion other than 40, in the easily separable composite cap in which the lower end edge of the cap peripheral wall 30 and the upper end edge of the ring C are connected by a plurality of easily cutable connecting pieces 41 in the circumferential direction. A pair of slits 42 is provided at positions on both sides of the connecting portion 40.

The second means is configured as follows. That is, at the first hand stage, the in plug A, the fitting tube 13 constituted by vertically through the flange 12 extending onto the neck 101 of the upper end edge of the mounting cylinder 10 The outer peripheral lower end portion of the cap peripheral wall 30 and the upper end portion of the ring C located on the outer periphery of the fitting cylinder 13 are connected by the connecting portion 40 and the easily cutable connecting piece 41.

The third means was configured as follows. That is, in either the first means or the second means, the inner plug A is formed of a soft plastic.

  Since the composite container of the present invention has a pair of slits 42 formed on both sides of the connecting portion 40 of the ring C, the connecting portion 40 can be connected even if the connecting width of the connecting portion 40 between the cap B and the ring C is small. It can be easily bent or curved, and can be easily handled and smoothly removed when removing the plug A. Further, even when the width of the connecting portion 40 is large in order to obtain sufficient strength of the connecting portion 40, the connecting portion 40 can be easily bent or curved by adjusting the slit 42 to be longer. it can. Further, since the force for removal is transmitted through the cap B that is detachably fitted and locked around the fitting cylinder 13, the force tends to be exerted over the entire fitting cylinder 10 of the inner plug A. Yes, it can be easily removed at the time of disposal after use of the container, its operation can be performed very easily, and separation and disposal can be easily performed. In addition, there is an advantage that removal can be performed without requiring a jig or the like. Further, since the ring C is configured as a part of the cap B with the peripheral wall 30 extended, the ring C does not get in the way of use and is very convenient to handle.

  When the locking means when the peripheral wall 30 is fitted to the outer periphery of the fitting cylinder 13 is screwed, the cap B can be easily attached and detached, and the peripheral wall from the ring C when discarded after use of the container There is no possibility that the fitting tube 13 and the peripheral wall 30 will come off even when a large force is applied to pull up 30 upward, and the mounting tube 10 can be detached from the mouth-and-neck portion 101 more reliably.

  The inner plug A is configured by connecting the upper end edge of the mounting cylinder 10 and the lower end edge of the fitting cylinder 13 by a flange 12 extending on the mouth and neck portion 101, and the outer peripheral lower end portion of the cap peripheral wall 30; When the upper end portion of the ring C positioned on the outer periphery of the fitting cylinder 13 is connected by the connecting portion 40 and the easily cut connecting piece 41, the presence of the diameter difference between the ring C and the cap B is the presence of the slit 42. In combination, there is an advantage that the ring C can be rotated without difficulty. In addition, the screwing end point of the cap peripheral wall 30 can be reliably identified, and the fitting of the mounting cylinder 10 becomes a firm and strong fitting.

  When the inner plug A is formed of a soft plastic, the mounting cylinder 10 or the like that is the engaging portion is easily deformed and is more easily removed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  1 to 5 show an example of an easily separable composite cap 1, and the composite cap 1 includes an inner plug A, a cap B, and a ring C.

  The composite cap 1 is used by being attached to the mouth / neck portion 101 of the container body 100. On the outer periphery of the mouth and neck portion 101 of the container body 100, a locking protrusion 102 for locking the inner plug A to be mounted is provided.

  The inner plug A is attached to the container body 100 by fitting the mounting cylinder 10 on the outer periphery of the mouth and neck portion 101. An engaging protrusion 11 is provided at the lower end of the inner periphery of the mounting cylinder 10, and the engaging protrusion 11 is engaged with the engaging protrusion 102 on the outer periphery of the mouth-and-neck portion 101 to prevent it from coming out upward. I am trying. Further, a flange 12 is extended inward from the upper end of the mounting cylinder 10, and a fitting cylinder 13 is provided above the inner peripheral edge of the flange 12, with a screw thread provided around the outer periphery. Further, a seal cylinder 14 suspended downward from the inner peripheral edge of the flange 12 is fitted in a liquid-tight manner to the upper end of the inner periphery of the mouth-and-neck portion 101 so that liquid-tightness is imparted to this portion.

  In addition, the upper part of the outer surface is integrally connected to the inner peripheral edge of the flange-like top plate 15 extending inwardly from the upper end edge of the peripheral wall 30, and the dispensing cylinder 16 is suspended in a double cylinder shape inside the fitting cylinder 13. Has been established. The upper end portion of the dispensing tube 16 is spread out in a trumpet shape above the fitting tube 13, and the inside and outside of the container body 100 are blocked by a blocking wall 17 provided horizontally at the lower end portion. A removal wall portion 17a surrounded by a linear thin-wall portion 18 is defined on the blocking wall 17, and a pull ring 20 is erected from above the removal wall portion 17a via a support column 19. The plug A can be formed of a general synthetic resin such as a thermoplastic synthetic resin. However, for example, if a soft plastic as defined by ASTM is used, it can be easily removed.

  The cap B has a cylindrical shape with a lower end opening in which a top wall 31 is extended from an upper end edge of a peripheral wall 30 provided with a thread on the inner periphery, and a ring C is integrally suspended from the lower end edge of the peripheral wall. The peripheral wall 30 is screwed onto the outer periphery of the fitting cylinder 13 and is detachably attached to the inner plug A. At this time, the lower surface of the peripheral wall 30 is configured to contact the upper surface of the flange 12 at the screwing end point position. In addition, from the back surface of the top wall 31, a seal cylinder part 32 that is liquid-tightly fitted to the inner peripheral upper end part of the dispensing cylinder 16 is suspended, so that when the cap B is mounted, that part is sealed. It is composed. Note that the means for locking the cap B to the fitting cylinder 13 is not limited to the screwing as in this example, and for example, an L-shaped engaging groove provided on the outer periphery of the fitting cylinder 13 is provided on the inner surface of the cap peripheral wall 30. A so-called twist lock system can be used in which the protruding engaging protrusion is locked by lowering the vertical portion of the engaging groove and then rotating to the horizontal portion, and can be locked while preventing other upward slipping. Known means can be employed.

  The ring C is formed integrally with the cap B and a synthetic resin, and connects a part of the upper edge of the cap C and a part of the lower edge of the cap peripheral wall 30 via the connecting part 40. In the non-connecting portion, the two are connected by a plurality of easily cut connecting pieces 41 in the circumferential direction. Further, a pair of slits 42 that extend both sides of the connecting portion 40 are provided at positions on both sides of the connecting portion 40 of the ring C. The connecting portion 40 is capable of rotating the ring C around the portion at the time of disposal, and it is necessary not to cut even if the cap B is fitted to the inner plug A after being rotated and pulled up strongly. . Therefore, in order to satisfy these requirements, a predetermined thickness, width, cut width of the slit 42, and the like are set.

  For the convenience of rotating the ring C, it is advisable to provide a gap between the lower end edge of the cap peripheral wall 30 and the upper end edge of the ring C, and the connection width of the connecting portion 40 is increased accordingly, thereby drawing out the ease of rotation. be able to. In the illustrated example, the ring C is formed to have a larger diameter than the outer periphery of the cap peripheral wall 30, and the upper end of the ring C and the lower end of the outer peripheral surface of the cap peripheral wall 30 are connected by the connecting portion 40 and the easily cutable connecting piece 41. As shown in FIG. 4, a plurality of easily cut connecting pieces 41 are provided at substantially equal intervals in the circumferential direction between the lower end edge of the cap peripheral wall 30 and the upper end edge of the ring C in the non-connecting portion other than the connecting portion 40. .

  A case where the easily separable composite cap 1 configured as described above is used will be described. First, the peripheral wall 30 is rotated from the state shown in FIG. 1 to unscrew the cap B, and the cap B and the ring C can be removed from the inner plug A. Next, when the pull ring 20 is grasped and pulled up, the linear thin-walled portion 18 is broken and the spout is opened in the blocking wall 17. In this state, the liquid in the container body 100 can be used by being poured out from the dispensing tube 16 through the dispensing port. If the cap B is screwed after the liquid is dispensed, the seal cylinder portion 32 is fitted into the dispense cylinder 16 to prevent liquid leakage and the cap B can be attached. At this time, the ring C is fitted to the outer periphery of the mounting cylinder 10.

  When separating and discarding the container body 100 and the composite cap 1 after using the inner solution, first, the cap B is screwed together with the ring C, and then the ring C is pulled with the cap B. While cutting each easily cutable connecting piece 41, the ring C is rotated with respect to the cap B around the connecting portion 40, and the cap B is rotated again to a position where it can be screwed to the inner plug A. At this time, due to the presence of each slit 42, even the connecting portion 40 having a sufficiently large width to obtain strength can be easily bent. Thereafter, as shown in FIG. 5, the cap B is screwed onto the inner plug A in this state. Next, when the ring C is pulled upward from this state, the cap B and the inner plug A are screwed together and thus cannot be removed, and the inner plug A is lifted and removed from the container body 100.
