Description

  The present invention relates to a container with an inner stopper, and more particularly to a container with an inner stopper in which the inner stopper can be removed from the container body at the time of disposal.

  For containers such as dressing, a container with a stopper is generally employed. In the container with an inner stopper, an annular recess that opens downward is defined by a large-diameter cylindrical wall, a small-diameter cylindrical wall, and an annular wall that connects the upper ends thereof to the lower part of the inner stopper made of synthetic resin. The inner stopper is held between the container body by fitting the annular recess into the mouth of the container body.

  By the way, in recent years, it has been demanded to be disposed of separately. For example, when the container main body is formed of glass and the inner plug is formed of synthetic resin, the inner plug is disposed of when the container is discarded. Must be removed from. However, since the inner stopper is firmly fitted to the container body, it is not easy to remove the inner stopper from the container body unless an instrument or the like is used. Therefore, the large-diameter cylindrical wall of the inner plug that is fitted to the mouth of the container body is doubled to ensure strength, and when the inner plug is detached from the container main body, the outer peripheral wall of the large-diameter cylindrical wall The large-diameter cylindrical wall can be deformed by stripping off, thereby facilitating the removal of the inner plug (see, for example, Patent Documents 1 and 2).

  The inner plug removal structure as described above is based on the assumption that the large-diameter cylindrical wall of the inner plug is exposed. In other words, when the container with an inner stopper is a type in which a skirt-shaped cylindrical wall extending downward in the radial direction is attached to the large-diameter cylindrical wall for fitting the inner stopper to the container main body, the above-described removal structure is adopted. Can not do it.

  The present invention has been made in view of the above-described background art, and even if a large-diameter cylindrical wall for fitting the inner plug to the container body is covered by a skirt-shaped cylindrical wall, An object of the present invention is to provide a container with a stopper that can be easily separated.

  In order to solve the above-described problems, a container with an inner stopper according to the present invention includes an annular fitting portion fixed to a mouth portion of a container body and a skirt-shaped first cylindrical wall that covers the annular fitting portion from the radially outer side. A container with an inner stopper having an inner stopper as a base, wherein the annular fitting portion includes a second cylindrical wall, a third cylindrical wall having a smaller diameter than the second cylindrical wall, and the second and third cylindrical walls. An annular wall connecting the upper ends to each other, sandwiching the mouth of the container body between the second and third cylindrical walls, the annular wall having a notch on at least a part of the lower surface, the first cylindrical wall And a slit extending from the lower end of the first cylindrical wall to the annular wall and extending from the lower end of the second cylindrical wall to the annular wall.

  According to the container with an inner stopper of the present invention, when the finger is pulled away from the lower end portion of one of the first and second cylindrical walls defining the slit, the annular wall is sheared at the notch portion. Thereby, since one 2nd cylindrical wall which clamps the opening part of a container main body separates from a 3rd cylindrical wall, the clamping force of the container main body by a 2nd cylindrical wall is released. Therefore, since the annular fitting portion can be easily detached from the mouth portion of the container main body, the operation of removing the inner plug from the container main body at the time of disposal becomes simple.

  In a specific aspect of the present invention, the slit is formed so as to be inclined in the circumferential direction at least at the upper portion with respect to the axis of the base portion. In this case, it is easy to apply a force that shears the notch in the upper part of the slit, and the second cylindrical wall is easily separated from the third cylindrical wall.

  In another aspect of the present invention, the lower end of the first cylindrical wall is cut away at the place where the slit is provided, and the slit width is widened. In this case, it becomes easy to put a finger on the lower end of one of the two portions of the first cylindrical wall defining the slit.

  In yet another aspect of the present invention, a pair of ribs are disposed between the first cylindrical wall and the second cylindrical wall with a slit interposed therebetween. When the slit is formed, the clamping force of the second cylindrical wall may be reduced, but the second cylindrical wall is reinforced by the rib.

  In still another aspect of the present invention, the apparatus further includes a separation portion that is detachably connected to the base portion.

  FIG. 1 shows an embodiment of a container with an inner stopper according to the present invention. In the following embodiments, the positional relationship such as up and down will be described in a state where the axis AX of the container 100 with the inner stopper is set up vertically.

  A container 100 with an inner stopper shown in FIG. 1 includes an inner stopper 10 that is locked to the container body 1 and an upper lid 20 that is screwed onto the inner stopper 10 so as to cover the inner stopper 10. The container body 1 can store liquid and other contents.

  Referring to FIGS. 1 and 2, the inner plug 10 is an integrally molded product made of resin such as polyethylene by molding, and includes a base portion 11 fitted into the mouth portion 1 a of the container body 1, and a base portion 11 when opened. And a separation part 12 to be separated.

  The base portion 11 of the inner stopper 10 has an annular fitting portion 11j that is fixed to the end portion of the mouth portion 1a of the container body 1 by fitting. The annular fitting portion 11j is a large-diameter second cylindrical wall 11a attached to the outer peripheral surface of the mouth portion 1a of the container body 1 and a small-diameter third portion attached to the inner peripheral surface of the mouth portion 1a of the container body 20. The cylindrical wall 11b is constituted by a flange-shaped annular wall 11c connecting the upper ends of the second and third cylindrical walls 11a and 11b. A bulging portion 11d is formed in the circumferential direction on the inner peripheral surface of the second cylindrical wall 11a. A skirt-shaped first cylindrical wall 11e extending downward to cover the mouth portion 1a of the container body 1 is connected to the outer peripheral end of the flange-shaped annular wall 11c. A male screw 11f is formed on the outer peripheral surface of the first cylindrical wall 11e. In the base 11, the second cylindrical wall 11 a and the first cylindrical wall 11 e that covers the second cylindrical wall 11 a from the periphery are the outer peripheral part 11 o of the double structure of the base 11.

  Further, an upper cylindrical wall 11g is extended as a spout part above the second cylindrical wall 11b provided in the base 11. The upper cylindrical wall 11g is narrowed upward, and a lip 11h extending outward in the radial direction is formed at the tip thereof.

  In this inner plug 10, as shown in FIGS. 2 and 3, a slit 13 extending from the lower end of the first cylindrical wall 11e to the annular wall 11c and extending over the entire length of the second cylindrical wall 11a is formed. . That is, the slit 13 extends from the lower end of the first cylindrical wall 11e to the annular wall 11c and extends from the lower end of the second cylindrical wall 11a to the annular wall 11c. The slit 13 includes a lower slit 13a formed in a vertical direction or a direction parallel to the axis AX in the first cylindrical wall 11e and the second cylindrical wall 11a, and a circumferential direction to the annular wall 11c continuously from the lower slit 13a. The upper slit 13b is formed obliquely toward one of the two. The upper slit 13b is inclined in the circumferential direction with respect to the axis AX of the base 11, and is inclined with respect to the radial direction with respect to the axis AX. This slit 13 is formed so that the width becomes narrower as it goes upward. At the place where the slit 13 is provided, the lower end of the first cylindrical wall 11e is cut away to widen the slit width. More specifically, a notch 13c for inserting a finger or the like is formed in one lower end portion 11m of the portion 11k that defines the lower slit 13a in the first cylindrical wall 11e. That is, the other lower end portion 11n of the portion 11k defining the lower slit 13a functions as a finger hook when the annular fitting portion 11j is partially broken in order to remove the inner stopper 10 from the container body 1.

  As shown in FIGS. 4 and 5, in the annular fitting portion 11 j of the inner plug 10, more specifically, at the outer periphery of the upper end of the second cylindrical wall 11 a or the outer periphery of the base portion of the upper cylindrical wall 11 g, An arc-shaped notch 14 concentric with the second cylindrical wall 11a or the upper cylindrical wall 11g is formed on the back surface. The arc-shaped notch 14 is formed over an angular range of 1/4 or more of the entire circumference of the annular wall 11c, preferably over an angular range of 1/3 to 1/2 or more of the entire circumference of the annular wall 11c. The arc-shaped notch 14 is obtained by forming a thin-walled portion, and preferably has such a thickness that the annular wall 11c of the annular fitting portion 11j can be easily cut by hand. When the material 10 is polyethylene, it is preferable to set the thickness to about 0.15 to 0.3 mm. One end of the arcuate notch 14 is continuous with the upper end of the slit 13. That is, the arc-shaped notch 14 extends from the upper end of the slit 13 along the outer periphery of the base portion of the upper cylindrical wall 11g in a counterclockwise direction over a predetermined angle.

  As shown in FIG. 5 and the like, a pair of ribs 15 are disposed between the second cylindrical wall 11a and the first cylindrical wall 11e with the slit 13 therebetween. More specifically, a first rib 15a is formed on one side of the portion 11k that defines the lower slit 13a so as to pass from the first cylindrical wall 11e to the second cylindrical wall 11a, thereby defining the lower slit 13a. A second rib 15b is formed on the other side of the formed portion 11k so as to pass from the first cylindrical wall 11e to the second cylindrical wall 11a. Further, the space between the second cylindrical wall 11a and the first cylindrical wall 11e is not limited to one place along the circumference, but a plurality of places along the circumference (for example, 6 to 24 places, in the illustrated example, 6 places). ), Ribs 15z arranged radially can be provided in addition to the ribs 15a and 15b. By providing the ribs 15z at a plurality of locations along the circumference of the second cylindrical wall 11a, the fitting force of the inner plug 10 with the container body 1 increases, and the inner plug 10 comes off at an unintended timing such as during transportation. Can be prevented.

  1 and 5, the separating portion 12 of the inner plug 10 closes the cylindrical wall 12a concentric with the upper cylindrical wall 11g and formed on the inner diameter side of the upper cylindrical wall 11g, and the lower end opening of the cylindrical wall 12a. And a disk-shaped sealing body 12b formed as described above. And the annular score 12d which comprises a thin part is formed in the outer peripheral peripheral lower surface of the sealing body 12b. Moreover, the internal thread 12c used as the reverse thread with respect to the external thread 11f of the 1st cylindrical wall 11e is formed in the internal peripheral surface of the cylindrical wall 12a.

  Referring to FIG. 1, an upper lid 20 is an integrally molded product made of resin by molding, and has an outer shape formed by a ceiling wall 20a and a cylindrical peripheral wall 20b that is curved from the ceiling wall and extends downward. Yes. A female screw 20c is formed on a lower inner peripheral surface of the peripheral wall 20b. The female screw 20c is screwed into the male screw 11f provided on the base 11 of the inner plug 10. A supporting cylindrical wall 20d is integrally formed on the lower surface of the ceiling wall 20a. A male screw 20e is formed on the outer peripheral surface of the supporting cylindrical wall 20d. The male screw 20e is screwed into a female screw 12c provided on the separating portion 12 of the inner plug 10. Is formed. Further, the lower surface of the ceiling wall 20a and the inner surface of the peripheral wall 20b are concentric with the supporting cylindrical wall 20d and have a small-diameter cylindrical wall 20f, a medium-diameter cylindrical wall 20g, and a large-diameter that are larger in diameter than the supporting cylindrical wall 20d. A cylindrical wall 20h is integrally formed.

  Hereinafter, the assembly of the container 100 with the inner stopper will be described. First, a recess defined by the second and third cylindrical walls 11 a and 11 b and the annular wall 11 c of the inner plug 10 is fitted into the mouth 1 a of the container body 1. At this time, the bulging portions 11d and 1b are locked together so that the bulging portion 11d of the second cylindrical wall 11a gets over the bulging portion 1b of the mouth portion 1a of the container body 1.

  Next, the upper lid 20 is put on the inner plug 10, the female screw 20 c of the upper lid 20 is engaged with the male screw 11 f of the first cylindrical wall 11 e of the inner plug 10 by screwing, and the male screw 20 e of the upper lid 20 is engaged with the female screw 12 c of the inner plug 10. Engage. At this time, since the screwing portions of the female screw 12c and the male screw 20e and the screwing portion of the male screw 11f and the female screw 20c are opposite to each other, at least one of the screwing portions gets over without being screwed. Forcibly engaged. Specifically, the upper lid 20 is put on the inner plug 10 and rotated clockwise to be screwed, so that the female screw 20c and the male screw 11f constituting the first screwing portion are screwed and tightened, and the second screw The male screw 20e and the female screw 12c constituting the threaded portion engage with each other by overcoming the thread.

  The inner plug 10, the container main body 1, and the upper lid 20 can also be assembled by assembling the inner plug 10 and the upper lid 20 in advance, and then attaching the inner plug 10 to the mouth 1 a of the container main body 1.

  In this state, as shown in FIG. 1, the small-diameter cylindrical wall 20f of the upper lid 20 is located between the cylindrical wall 12a of the inner plug 10 and the upper cylindrical wall 11g, and the lower end of the small-diameter cylindrical wall 20f is the inner plug 10's. Opposite the circular score 12d.

  Hereinafter, opening of the container 100 with an inner stopper will be described. When the upper lid 20 is rotated in the loosening direction with respect to the container body 1, the female screw 20c and the male screw 11f constituting the first screwing portion are loosened and the male screw 20e and the female screw 12c constituting the second screwing portion are tightened. Is included. That is, the separating portion 12 of the inner plug 10 is fastened to the supporting cylindrical wall 20 d of the upper lid 20, that is, pulled up together with the upper lid 20. Therefore, the separation part 12 is sheared from the base part 11 in the annular score 12d shown in FIG. As a result, the inner plug 10 is opened.

  The closing after opening the container 100 with the inner stopper will be described. When the upper lid 20 after opening is put on the inner plug 10 again, and the female screw 20c of the upper lid 20 is screwed into the male screw 11f of the inner plug 10 and tightened, the lip 11h of the inner plug 10 is attached to the inner surface of the ceiling wall 20a of the upper lid 20. It abuts and closes the upper opening of the inner plug 10.

  The handling of the used container 100 with the inside stopper will be described. In order to separate and discard the inner stopper 10 from the container body 1 after using the contents of the container 100 with inner stopper, the portion 11k of the first and second cylindrical walls 11e and 11a defining the slit 13 When the lower end portion 11n is put on a finger and pulled away, the annular wall 11c is sheared at the arc-shaped notch 14 portion. Thereby, since one 2nd cylindrical wall 11a which clamps the opening part 1a of the container main body 1 separates from the 3rd cylindrical wall 11b, the clamping force of the container main body 1 by the 2nd cylindrical wall 11a is released. Therefore, since the annular fitting portion 11j can be easily detached from the mouth portion 1a of the container main body 1, the operation of removing the inner plug 10 from the container main body 1 at the time of disposal becomes simple. Further, since the pair of ribs 15 are arranged with the slit 13 interposed therebetween, the force to put the finger on the lower end portion 11n and pull it apart is transmitted to the second cylindrical wall 11a through the rib 15, so the finger is put on the lower end portion 11n. It is possible to easily shear to the arc notch 14 simply by pulling apart.

  In addition, the material of the container main body 1 to which the above embodiment is applied may be any of synthetic resin, glass, and metal.

  Moreover, in the said embodiment, although the screw mechanism which isolate | separates the isolation | separation part 12 of the inner stopper 10 with the internal thread 12c formed in the internal stopper 10 and the external thread 20e formed in the upper cover 20 is employ | adopted, it replaces the inside and outside, and an internal stopper It is also possible to form a male screw on 10 and a female screw on the upper lid 20.

  For example, a flange projecting radially outward from the separating portion 12 is formed on the separating portion 12 of the inner plug 10 without depending on the screw mechanism, and the periphery of the flange is formed in the radially inward direction formed on the upper lid 20. The present invention can also be applied to an inner plug that is separated from the base 11 by a protruding annular protrusion or the like. Furthermore, it is good also as a structure which provides the pull ring which applies a finger to the separation part 12 of the inner plug 10, and removes the separation part 12 with a finger.

  Moreover, in the said embodiment, although the inner stopper 10 provided with the isolation | separation part 12 is shown, the inner stopper which does not have the isolation | separation part 12 may be sufficient.

  In the above embodiment, the upper lid 20 is screwed to the outer periphery of the base 11 of the inner plug 10, but the upper lid 20 may be screwed to the container body 1.

  In the illustrated example, a notch 13c for inserting a finger or the like is formed in one lower end portion 11m of the portion 11k that defines the slit 13, but the other lower end of the portion 11k that defines the slit 13 is formed. You may form the notch for inserting a finger etc. in the part 11n.
