  This type of container cap is widely used for drink-type beverage containers used in drinks, refill containers, and the like. For example, the one disclosed in Patent Document 1 is known.

  This is because the body part that fits into the inner wall of the bin mouth is crowned by the disk part, and the disk part and the annular handle part that is concentrically located outside of the disk part can be partly broken, partly integrated The body portion is pulled out from the bottle opening and opened by pulling up the annular handle portion.

Japanese Patent No. 4152717

  However, in this conventional container cap, the body part is merely fitted to the inner wall of the bottle mouth, and there is a possibility that the breakable connecting part can be pulled out from the dispensing opening of the container. The problem remains in that it cannot be surely determined whether or not opening has been performed.

  The object of the present invention is to increase the fitting force with respect to the dispensing opening of the container and perform reliable sealing of the container, but it is possible to easily open the container at the time of opening, and it is illegal to open the container properly. An object of the present invention is to propose a container cap that can reliably determine whether or not opening has been performed.

The container cap according to the present invention integrally connects a top plate that closes the dispensing opening of the container to an inner and outer double cylindrical body that forms an annular groove opened downward, and the annular groove is connected to the mouth and neck of the container. A container cap comprising a base that is fitted and fixed to the tip, and an annular band that surrounds the base and reinforces the fitting force to the tip of the mouth and neck of the cylinder,
Between the base and the annular band, a top surface weakening piece that detachably connects the base and the annular band at at least a part of the upper end portion of the top surface, and a position below the top surface weakening piece the connecting piece is detached from the mouth and neck tip of the container the base provided by breaking the top panel surface weakening pieces by causing the annular band while inseparably connecting the base and the annular band, is the top panel surface weakening piece In the lower region excluding the provided region, at least one weakening bridge that detachably connects the base and the annular band is provided .

In the present invention, it is preferable to add the following components to the container cap having the above-described configuration. That is,
1) The top surface weakening piece is provided at a lateral position on the front side of the annular band that is the starting point of the annular band.
2 ) Provide a protective projection adjacent to the weakening bridge on at least one of the outer peripheral wall of the base and the inner peripheral wall of the annular band. further,
3 ) Providing a protective projection adjacent to the top surface weakening piece on at least one of the outer peripheral wall of the base and the inner peripheral wall of the annular band.

  Here, “adjacent to the top surface weakening piece” and “adjacent to the weakening bridge” are literally adjacent to each other, as well as being located away from the top surface weakening piece, the weakening bridge, or the top surface weakening piece. In addition, the case where it is integrally connected to the edge of the weakening bridge is also included.

  In addition, “protective protrusions” can be protrusion-shaped or rib-shaped, and are adjacent to the top surface weakening piece or the portion (one of the base or annular belt) where the weakening bridge remains. It can be provided not only in the case of, but also in at least one of the upper and lower sides.

  Moreover, in order to make the top surface weakening piece and the weakening bridge easy to break, it is preferable to provide a scheduled end portion such as a thin-walled portion, a perforated hole or a slit-like cut. About a protection protrusion, it is preferable to provide in the outer peripheral wall of the outer cylinder which comprises a base.

  According to the container cap of the present invention having the above structure, an annular band is provided around the base, and the annular band is made to function as a ridge of the base, so that the container cap can be more fitted to the mouth-neck portion of the container. Become strong.

  Further, according to the container cap of the present invention, it is possible to weaken the fitting force of the container cap at the mouth-neck portion of the container by causing the annular band, and the container can be simply pulled up through the connecting portion. Can be opened easily.

  Further, according to the container cap of the present invention, when the annular band is caused, the top surface weakening piece is broken, so whether or not the container cap is unfairly opened before the container is properly opened is determined. It can be easily identified by simply viewing the surface side.

  Further, according to the container cap of the present invention, the top surface weakening piece is provided at a lateral position on the front side of the annular band that causes the annular band, and the direction and the top surface weakening are caused. The direction in which the pieces break is almost the same, and the top weakened piece can be smoothly broken with a smaller force.

  According to the container cap of the present invention, since the at least one weakening piece for detachably connecting the base and the annular band is provided in the lower region excluding the region where the top surface weakening piece is provided, the annular band is provided. The mounting posture with respect to the base can be stably maintained.

  Further, according to the container cap of the present invention, since the protective projection adjacent to the weakening bridge is provided on at least one of the outer peripheral wall of the base and the inner peripheral wall of the annular band, at the breakage point of the weakening bridge when the container is opened, Even if an inward or outward rupture mark with a sharp tip is generated, it becomes possible to reduce the degree of contact of the rupture mark to the finger of the consumer who performs the opening operation under the action of the protective protrusion, The unpleasant irritation caused thereby is reduced.

  In particular, in the case where a protective projection is provided at a site adjacent to the top surface weakening piece, even if an inward or outward breaking mark occurs at the tip of the top surface weakening piece, the tip is sharp, Under the action of the protective protrusion, it is possible to reduce the degree of contact of the fracture mark with the finger of the consumer who performs the opening operation, thereby reducing unpleasant irritation.

  1-4, the code | symbol 1 is a cap for containers. The container cap 1 forms a top plate 1a that closes the pouring opening 2a of the mouth-neck end 2 of the container, and an annular groove 1b that is open at the top by connecting the top ends together, and connects the bottom end at the inside. And a base 1e configured by inner and outer cylinders 1c and 1d connected to the portion 1h (hereinafter, the inner cylinder is indicated by the inner cylinder 1c and the outer cylinder is indicated by the outer cylinder 1d). .

  This base 1e is configured to fix and hold the base 1e by fitting an annular groove 1b between the inner cylinder 1c and the outer cylinder 1d to the mouth neck portion 2 of the container with a stopper. On the outer side, an annular band 3 is provided that surrounds the base 1e and reinforces the fitting force of the inner cylinder 1c and the outer cylinder 1d with respect to the distal end 2 of the neck. The annular band 3 protrudes radially outward on an outer wall on the front surface side (the formation position of the connecting piece with respect to the central axis is an outer peripheral surface facing the diameter direction), for example, a lip-shaped planar shape. A finger-hanging piece 3a is provided.

  1 (a) and 1 (b), the mouth and neck tip 2 is formed by undercut fitting between the inner protrusion 1f of the outer tube 1d and the outer protrusion 2b of the mouth and neck tip 2. Is fitted and fixed between the inner cylinder 1c and the outer cylinder 1d.

  Reference numeral 4 denotes a top weakening piece provided between the outer cylinder 1d of the base 1e and the annular band 3. The top surface weakening piece 4 is formed of a thin plate-like member that detachably connects the outer cylinder 1d and the annular band 3 of the base 1e at at least a part of the upper end portion of the top surface. When gripping the finger-hanging piece 3a to cause the strip 3 to separate the outer cylinder 1d of the base 1e and the annular band 3, the top surface weakening piece 4 starts to break from the front edge 4a and breaks at the rear edge 4b. Completion | finish, Comprising: The fracture | rupture planned end (line | wire) 4c is formed between this front side edge 4a and the rear side edge 4b.

  Here, as at least a part of the upper end of the top surface, the top surface weakening piece 4 is placed at a lateral position on the front side of the annular band 3 that is the starting point of the annular band 3 (the side on which the finger hanging piece 3a is provided). Two of the front side edge 4a, the rear side edge 4b, and the expected breaking end 4c connecting these are made to coincide with the outer peripheral wall of the outer cylinder 1d of the base 1e, whereby the top surface weakening piece 4 is attached to the outer periphery of the outer cylinder 1d. Although an example in which the material is broken along the wall is shown as an example, the top surface weakening piece 4 is broken by making the front side edge 4a, the rear side edge 4b, and the planned breaking edge 4c coincide with the inner peripheral wall of the annular band 3. However, this point is not limited.

  When the front side edge 4a, the rear side edge 4b, and the planned fracture end 4c are made to coincide with the outer peripheral wall of the base 1e and the top surface weakening piece 4 is broken, the fracture mark remains on the inner circumferential wall of the annular band 3. On the contrary, when the top surface weakening piece 4 is broken by making the front side edge 4a, the rear side edge 4b, and the planned breaking edge 4c coincide with the inner peripheral wall of the annular band 3, the breaking mark is the base 1e. Will remain on the outer peripheral wall of the outer cylinder 1d. In order to facilitate breakage of the top surface weakening piece 4, it is preferable that the planned break end 4 c be formed by a thin portion, perforated perforations, slit-like cuts, or the like.

  The planar shape of the top surface weakening piece 4 can be appropriately changed as necessary, and is not limited to the illustrated one.

  Reference numeral 5 denotes a connecting piece that connects the outer cylinder 1d of the base 1e and the annular band 3 in an inseparable manner. The connecting piece 5 is provided at a position below the top surface weakening piece 4 on the back side of the base 1e (opposite position where the finger hanging piece 3a is provided), and causes the annular band 3 to open the container. At this time, the base 1e is detached from the mouth / neck tip 2 of the container through the connecting piece 5.

  The connecting piece 5 only needs to be provided below the top surface weakening piece 4, but in particular, it is preferably provided at the lower end of the outer cylinder 1 d of the base 1 e and the lower end of the annular band 3. When this occurs, the inner peripheral projection 1f provided on the outer cylinder 1d is pulled outward in the radial direction, so that the fitting with the outer peripheral protrusion 2b provided on the distal end 2 of the neck and neck is easy to be released. The container can be opened with a smaller force.

  Reference numeral 6 denotes a weakening bridge provided in a lower region excluding the region where the top surface weakening piece 4 is provided, in particular, at the lower ends of the base 1 e and the annular band 3. The weakening bridge 6 connects the base 1e and the annular band 3 so as to be separable, and the weakening bridge 6 stabilizes the mounting posture of the annular band 3 with respect to the base 1e. This weakening bridge 6 breaks when the annular band 3 is raised.

  At least one weakening bridge 6 is provided. In the case where a plurality of weakened bridges 6 are provided, it is preferable to arrange them at intervals along the periphery of the base 1e.

  The planar shape of the weakening bridge 6 is exemplified as a trapezoidal shape that tapers toward the annular band 3, but the location of the weakening bridge 6, the planar shape, and the like can be changed as appropriate.

  When the planar shape of the weakened bridge 6 is a trapezoidal shape that tapers toward the annular band 3 and the cross-sectional shape is gradually thinned toward the annular band 3, the weakened bridge 6 is applied. 6 is located at a connection portion with the annular band 3 (a boundary between the annular band 3 and the weakening bridge 6), and the breakage mark of the weakening bridge 4 remains on the outer cylinder 1d side when unplugged. In particular, when the fracture mark of the weakened bridge 4 remains on the outer cylinder 1d side, when the finger is put on the annular band 3 itself, an unpleasant stimulus to the finger due to the fracture mark of the weakened bridge 4 can be eliminated. There is.

  In addition, the division | segmentation planned end 6a of the weakening bridge 6 is good also as a connection part with the outer cylinder 1d, In that case, the fracture | rupture trace of the weakening bridge 6 with the pointed tip will remain on the inner peripheral wall of the annular band 3. .

  The planned split end 6a can be easily formed by changing the width shape and thickness of the weakening bridge 6 and changing its planar shape (change of the width dimension, etc.), It may be formed by providing perforated holes or slit-shaped cuts.

  Reference numeral 7 denotes a protective protrusion provided adjacent to the weakening bridge 6. The protective projection 7 is provided on one of the portions where the fracture marks of the weakened bridge 6 remain, that is, either the outer peripheral wall of the outer cylinder 1d of the base 1e or the inner peripheral wall of the annular belt 3, and When removing the container cap 1 from the cervical tip 2, the user's finger is protected from the rupture mark of the weakened bridge 6 with a sharp tip to reduce unpleasant irritation to the finger due to the rupture mark.

  The number of protection projections 7 can be varied in various ways as long as it is adjacent to the weakening bridge 6. Further, the shape of the protective projection 7 can be convex, and the protective projection 7 can be provided on at least one of the upper side and the lower side of the weakening bridge 6. It should be noted that the protective projection 7 is provided adjacent to the weakening bridge 6 as in the case of the protective projection 6 described above, when the protective projection 7 is spaced apart by about several millimeters or integrally with the weakening bridge 6. Includes cases where they are linked.

  In this embodiment, the top plate 1a for closing the dispensing opening 2a of the container has an outer peripheral edge integrated with the lower end portion of the inner cylinder 1c via the inner cylinder 1c, the annular peripheral wall 1g concentric with the outer cylinder 1d and the connecting portion 1h. Although what was connected was shown as an example, the outer periphery of the top plate 1a can also be integrally connected to the upper end part of the inner cylinder 1c. Moreover, it is also possible to provide the upper surface of the top plate 1a in the lower end part or lower position of the inner cylinder 1c, and this point is not limited to the illustrated one.

  In the container cap 1 having the above-described configuration, as shown by the arrows in FIG. 4, the top surface weakening piece 4 and the weakening bridge 6 positioned therebelow are broken to cause the annular band 3, and the annular band 3 By pulling up, one end portion (right end portion in the figure) of the base 1e is pulled up via the connecting piece 5. By this pulling, the undercut fitting between the mouth neck portion 2 of the container and the base 1e is on the one end side. And the container can be opened. At that time, the top surface weakening piece 4 and the weakening bridge 6 that connect the base 1e and the annular band 3 are already broken, and the fitting force of the outer cylinder 1d with respect to the mouth neck portion 2 of the container is reduced. The fitting between the mouth neck portion 2 and the base 1e can be easily released.

  Moreover, according to the container cap 1 having such a configuration, the fitting force of the annular band 3 to the mouth neck portion 2 of the container is reinforced before the opening, so that the top weakening piece 4 and the weakening bridge 6 are broken. The container cannot be opened unless the annular band 3 is caused, and if the container is opened illegally before the container is properly opened, the top surface weakening piece 4 is broken. Therefore, it is possible to easily and surely determine whether or not the unauthorized opening has been performed only by confirming whether or not the top surface weakening piece 4 is broken.

  The container cap 1 of the present invention has an advantage that the container cap 1 can be reused even after the container is opened, because the base 1 is maintained in its initial shape.

  FIG. 5 is a plan view showing another embodiment of the container cap 1 according to the present invention. The container cap 1 has a configuration in which the top surface weakening piece 4 is provided on the front side of the annular band 3 where the finger-hanging piece 3a is located, and the planned break ends 4e are formed between the both end edges 4d. In this case, the weakening bridge 6 is provided on the side of the front surface side of the annular band 3, and whether the top surface weakening piece 4 is broken as in the case of the container cap 1 shown in FIGS. Since it can be easily confirmed, it is easy to determine whether or not unauthorized opening has been performed before the container is properly opened.

  The cap for containers of the present invention may be provided with protective projections similar to the protective projections 7 adjacent to both end sides of the top surface weakening piece 4. By providing a protective projection similar to the protective projection 7, when the base 1e of the container cap 1 is detached from the mouth-neck tip 2 of the container, the user's finger is broken with a sharp tip on the top surface weakening piece 4 It is possible to protect from scratches, which can reduce unpleasant irritation to the fingers due to the fracture marks.

  It is important to provide the protective protrusion on the side where the fracture mark of the top surface weakening piece 4 remains, and when the fracture mark of the top surface weakening piece 4 remains on the outer peripheral wall of the outer cylinder 1d of the base 1e, A portion, that is, provided on the outer peripheral wall of the outer cylinder 1d.

  According to the present invention, the fitting force with respect to the dispensing opening of the container can be increased so that the container can be reliably sealed, while the container can be easily opened at the time of opening. Further, according to the present invention, it is possible to reliably determine visually whether or not unauthorized opening has been performed before the container is properly opened.
