Japanese Utility Model Publication No.58-113640

  In the above mouth structure, since the mouth part and the protective cover are integrally formed, the mold must be newly formed, and each time the mold is formed according to the difference in the size and the like of the container. There is a cost problem that must be achieved.

  The present invention has been made in view of the above points, and can be manufactured using a container composed of a container body and a cap that have been conventionally used, and it is obvious that the container is unused and unopened. In addition, the present invention proposes a container that can prevent mischief before opening, such as replacement of stored items, and that can be easily operated even when opening.

  In order to solve the above-mentioned problem, the invention according to the first aspect of the present invention extends the top wall 9 from the container body 2 with the mouth-and-neck part 7 upright and the upper edge of the peripheral wall 8 detachably fitted to the outer periphery of the mouth-and-neck part 7. And a cap 4 that covers the outer periphery of the peripheral wall 8 from above and prevents it from slipping out, and that includes a cut-off strip 16 that can be cut off vertically. It was comprised as a container characterized by.

  According to the second aspect of the present invention, the sealing cylinder 4 is prevented from coming out downward by the engaging portion a engaged with the upper surface of the cap, and is elastically engaged with the annular downward surface b of the outer peripheral portion of the container. The container according to claim 1, which is prevented from coming out upward by the piece 13.

  According to the present invention, the sealing tube 4 is prevented from coming out downward by abutting and locking the lower surface to the upper surface of the shoulder portion 6 of the container body 2 and also to the annular downward surface b of the outer peripheral portion of the container. The container according to claim 1, which is prevented from coming out upward by the elastic engagement piece 13 to be joined.

  According to a fourth aspect of the present invention, the elastic engagement piece 13 stands up from the lower surface of the window hole 14 provided at a predetermined position of the cylindrical wall of the sealing cylinder 4, and the tip protrudes inward of the cylindrical wall. The container according to claim 3 is configured.

  The invention according to claim 5 is configured as the container according to any one of claims 2 to 4, wherein the annular downward surface b is the lower surface of the cap peripheral wall 8.

  The container of the present invention is provided with a sealing tube 4 that covers the outer periphery of the peripheral wall 8 from above the cap 3 and prevents it from coming out, and is provided with a sealing tube 4 that is defined so as to be able to cut a longitudinally cut strip 16. As long as the cylinder 4 is not removed, the cap 3 cannot be removed, and it is possible to prevent mischief such as refilling of the contents and to obtain reliability for the contents. Moreover, since the conventional container other than the sealing tube 4 can be used as it is, it has the advantage that it can be manufactured at low cost. Further, since the sealing tube 4 can be easily removed by cutting and removing the cutting strip 16 by hand, the opening operation is easy.

  In addition, when the sealing cylinder 4 is provided with the elastic engagement piece 13 that stands up from the lower surface of the window hole 14 provided at a predetermined position of the cylindrical wall 4 and protrudes inward from the cylindrical wall, the sealing cylinder 4 is attached. In this case, since the elastic engagement piece 13 can be elastically deformed into the window hole 14, it can be easily attached and does not require an extra large gap with the cap 3, so that it looks good.

  Further, in the case where the elastic engagement piece 13 is engaged with the lower surface of the cap peripheral wall 8 to prevent upward slipping, there is an advantage that the sealing cylinder 4 can be formed in a simpler shape.

  1 to 3 show an example of a container 1 according to the present invention, and the container 1 includes a main body 2, a cap 3, and a sealing tube 4.

  The main body 2 is configured such that a mouth-and-neck portion 7 is raised from an upper end portion of a cylindrical trunk portion 5 via a shoulder portion 6. The cap 3 has a top wall 9 extending from the upper end edge of the peripheral wall 8 screwed to the outer periphery of the mouth-and-neck portion 7, and is detachably attached to the main body 2. In the figure, reference numeral 10 denotes a seal cylinder that is suspended from the back surface of the top wall 9 and fitted to the inner periphery of the mouth neck 7.

  The sealing cylinder 4 is formed of synthetic resin or the like, and has a cylindrical shape that covers the outer periphery of the cap peripheral wall 8 from above the cap 3 and prevents the cap 3 from coming out. Therefore, the container 1 of the present invention equipped with the sealing tube 4 is configured such that the sealing tube 4 cannot be removed due to obstruction even when the cap 3 is removed. Although it is preferable that the sealing tube 4 is basically attached to the cap 3 so as to be rotatable, a rotation preventing means for preventing rotation described later may be provided.

  As means for preventing the sealing tube 4 from coming out, there are means for preventing upward slipping and means for preventing downward slipping. The downward slip-off preventing means in the present invention is a container to be mounted. It depends on the form of the body 2. That is, when the protruding width of the shoulder portion 6 of the container body 2 is not so large or when the shoulder portion 6 is not present, the container body 2 is prevented from coming out downward by the engaging portion a engaged with the upper surface of the cap 3. As the engaging portion a, as shown in the embodiment of FIG. 1, a plurality of protrusions 11 that protrude from the inner peripheral upper portion of the sealing tube 4 at intervals in the circumferential direction and engage with the upper peripheral portion of the cap 3. In addition to the engaging portion a, the engaging portion a may be configured as a top wall 12 that closes the upper end opening of the sealing cylinder 4 as shown in FIG.

  Further, the shoulder portion 6 of the container body 2 is formed to be sufficiently larger in diameter than the mouth-and-neck portion 7, and the lower surface of the sealing tube 4 is brought into contact with and locked to the upper surface of the shoulder portion 6 protruding outward from the attached cap peripheral wall 8. If this is possible, as shown in FIG. 5, the lower surface of the sealing tube 4 can be brought into contact with the upper surface of the container body shoulder portion 6 to provide a slip-out preventing means.

  In addition, as a means for preventing the sealing tube 4 from coming out upward, in the present invention, an elastic engagement piece 13 that engages with the annular downward surface b of the outer periphery of the container 1 is provided. The elastic engagement piece 13 has a configuration in which the sealing cylinder 4 is mounted from above the cap, and is not engaged during the downward movement from the upper side, but is engaged when rising from the lower side. In addition, a configuration in which the upper surface forms an inclined surface inclined toward the horizontal plane or the cylinder wall side and the lower surface forms an inclined surface inclined toward the cylinder wall side is preferably employed. In the embodiment shown in FIG. 1, a configuration is adopted in which a pair of window holes 14 provided at predetermined positions on the left and right sides of the cylindrical wall of the sealing cylinder 4 are provided with their tips projecting inward. The elastic engagement piece 13 can achieve the intended purpose by being provided at one place, but it is naturally possible to provide a plurality of elastic engagement pieces 13 as shown in the example, and in that case, it is preferable to provide them at intervals, and Are preferably provided at equal intervals. Further, the installation location may be provided on the tube wall of the sealing tube 4 as in the embodiment of FIG. 1, or may be provided on a cut band portion described later, or may be provided on both.

  Further, in the embodiment of FIG. 1, the lower surface of the peripheral wall 8 of the cap 3 is adopted as the annular downward surface b of the outer peripheral portion of the container 1 described above, and an elastic engagement piece 13 is engaged with the lower surface of the peripheral wall 8 for sealing. This prevents the cylinder 4 from coming out upward. As the annular downward surface b, in addition to the lower surface of the cap peripheral wall 8, the lower surface of the flange 15 projecting from the outer periphery of the mouth neck portion 7 can be employed as shown in FIG.

  In addition, the sealing tube 4 defines a cut band 16 that cuts vertically. This cut band 16 is for removing the sealing tube 4 by cutting when the container 1 is used, and both sides are configured as an easily cut portion 17 that can be easily broken. Various specific forms of the easy-cutting portion 17 can be adopted, but in the embodiment shown in FIG. 1, a number of easily-cutting connecting pieces are provided at intervals on both side grooves of the cut band 16 defined by the grooves. ing. Alternatively, as shown in FIG. 7, a perforated easy-to-cut part 17 may be provided, and although not shown, the easy-to-cut part may be formed thin. As the form of the cut band 16 in the case of the sealing cylinder 4 having the top wall 12 as shown in FIG. 4, the intended purpose can be sufficiently achieved even if the cut band is formed only on the cylindrical wall portion. However, a cut band may be formed in a portion extending from the cylindrical wall to the top wall or a portion extending from the cylindrical wall to the opposing cylindrical wall. Further, the cut band 16 is not limited to being provided at one place as in the illustrated example, and may be provided at a plurality of places.

  In the case of using the container configured as described above, if the embodiment of FIG. 1 is introduced as an example, first, when the sealing tube 4 is mounted, the elasticity of the sealing tube 4 from above the cap 3 fitted to the container body 2. The sealing piece 4 may be fitted by sliding the engaging piece 13 while elastically deforming outward, and the elastic engaging piece 13 may be engaged with the lower surface of the cap peripheral wall 8. In this case, the sealing cylinder 4 is loosely fitted with a slight gap from the cap 3 and can be rotated with respect to the cap. Even if the sealing cylinder 4 is turned to unscrew the cap, only the sealing cylinder 4 is provided. The cap 3 is configured not to be screwed off.

  In this manner, it is preferable that the sealing tube 4 is rotatably attached to the cap. However, in order to prevent useless rotation, a rotation preventing means may be provided. For example, in FIG. 2, a plurality of circumferential ribs are provided at the lower end of the inner periphery of the sealing tube 4 so as to be pressed against the upper outer periphery of the body of the container body 2, thereby preventing unnecessary rotation of the sealing tube 4. Can be prevented.

  Further, when opening, the easy cutting part 17 is cut from the state of FIG. At this time, since the sealing cylinder 4 becomes an open cylinder, the diameter of the sealing cylinder 4 can be widened to easily release the engagement of the elastic engagement piece 13, and it can be removed from the container. Then, the cap 3 can be unscrewed.

  FIG. 8 shows still another embodiment, in which the sealing tube 4 covers not only the cap 3 but also the outer periphery of the container body 2. As described above, the size of the sealing cylinder 4 satisfies the requirement as long as it covers at least the outer periphery of the cap 3. Further, in this case, the elastic engagement piece 13 is provided at one place in the cut strip 16 portion and at three places at equal intervals on the other cylindrical wall portion of the sealing tube 4.
