As shown in FIGS. 1 and 2, the cap 1 of the present invention includes a circular top 2 and a cylindrical side 3. The cap 1 is made of a resin, and here, a cap molded using a polyethylene resin is used.

The circular top portion 2 is provided with two linear groove portions 4 that can be broken symmetrically and in parallel with each other so as to extend from the peripheral portion to the center of the top portion 2, and the two groove portions 4 have the peripheral portion. To the lower end of the side surface 3 in the vertical direction. The groove portion 4 has a reduced thickness for use as a cut line, and has a substantially V-shaped cross section. Here, the V-shaped angle of the substantially V-shaped cross section is 60 °, and the thickness of the bottom surface of the groove 4 is about 0.3 mm so that the groove 4 can be easily used as a cut line. The cross-sectional shape and bottom thickness of the groove 4 can be set as appropriate according to the material and size.

A portion sandwiched between the two groove portions 4 provided on the side surface 3 is further extended downward from the lower end of the side surface 2 to form a knob portion 6 having a shape in which the lower end protrudes outward. . The portion sandwiched between the two groove portions 4 and the knob portion 6 are used as tabs when the cap 1 is opened, and when the knob portion 6 is pulled upward, the groove portion 4 is broken, and FIG. As shown in (b), the tab portion is rolled up, and a part of the top portion 2 and the side surface 3 is cut out, which is a first stage for opening the cap 1. Thus, in order to cut out a part of the side surface 3 and the top portion 2, the groove portion 4 is provided. As shown in FIG. 5B, the knob portion 6 warps outward as it goes downward, thereby making it easier to pull the knob portion 6.

On the outer surface of the side surface 3, two ribs are provided at two positions facing each other in the vertical direction (horizontal direction in FIG. 1) with respect to the direction in which the groove portion 4 extends in the top portion 2 (vertical direction in FIG. 1). Part 5 is provided. As shown in FIG. 2, the collar portion 5 protrudes horizontally from the lower end of the outer surface of the side surface 3, and the planar shape thereof is a substantially crescent shape.

Engagement protrusions 7 are provided on the inner surface of the side surface 3 on the same circumference, and as shown in FIG. There is a portion where the protrusion 7 is not provided. The engaging protrusion 7 is fixed to the container body 11 by engaging with a lip 13 of the container body 11 described later.

When opening the cap 1, after the groove portion 4 is broken, if the cap 1 is removed from the container body 11 by applying an upward force to the collar portion 5, the engagement protrusion Although the engagement with the lip 13 is gradually released from the portions of the engagement protrusions 7 located on both sides of the portion where the 7 is not present, all the engagement is finally released and the cap 1 is removed. This stage is the second stage for opening the cap 1.

Further, as shown in FIG. 6, a protrusion or step 8 smaller than the engaging protrusion 7 is provided above the portion of the inner surface of the side surface 3 where the engaging protrusion 7 is provided. A packing 9 is held on the back surface of the top 2 by the step 8. The packing 9 is used to increase the sealing degree of the cap 1.

Next, the container 10 of the present invention using the cap 1 as described above will be described, and at the same time, the method for removing the cap 1 will be described.

As shown in FIGS. 2 and 3, the container 10 of the present invention includes the cap 1, the container body 11, and the inner lid 12. The container main body 11 and the inner lid 12 are also made of resin. Here, the container main body 11 is made of polypropylene resin, and the inner lid 12 is made of low-density polyethylene resin. The cap 1 is attached to the container body 11 by engaging the engagement protrusion 7 of the cap 1 with a lip 13 provided on the container body 11. As shown in FIG. 5, the lip 13 has a shape in which the upper end of the container body 11 is folded outward, and the lower end of the folded portion comes into contact with the engagement protrusion 7 to be engaged.

As shown in FIG. 5, the inner lid 12 is fixed in a state where its outer peripheral edge is fitted in a stepped portion 14 provided in the opening of the container main body 11, and closes the container main body 11, as shown in FIG. It becomes a state. And if the said cap 1 is attached to the container main body 11 closed with the said inner lid 12, as shown to Fig.2 (a), the said container 10 will be in the sealed state. In order to increase the sealing degree of the container 10, a protrusion is provided on a portion of the container body 11 that contacts the packing 9 so that the protrusion bites into the packing 9.

A handle 15 is provided on the upper surface of the inner lid 12 so that the inner lid 12 can be easily removed. The handle 15 can be bent, and as shown in FIG. 5, when the cap 1 is attached, the handle 15 is bent deeper.

Next, the usage method of the said container 10 is demonstrated. In general, the container body 11 is filled with a container, for example, a cosmetic cream, and closed with the inner lid 12 and the cap 1 as described above (see FIG. 2A). Sold as a cream.

The user replaces the container contained in the outer container for cream 20 whose surface is decorated with the container 10 containing new cream, thereby refilling the outer container for cream 20 with new cream. .

For that purpose, the cap 1 of the container 10 is removed. First, holding the knob portion 6 of the cap 1 and pulling it upward, the groove portion 4 of the side surface 3 is broken, and further force is applied to break the groove portion 4 of the top portion 3. Then, a portion sandwiched between the two groove portions 4 serving as tabs is turned upward, and a state as shown in FIG. 2B is obtained. This is the first stage for removing the cap 1.

In this way, when the side surface 3 and a part of the top portion 2 are cut out and then lifted by applying an upward force to one or both of the flange portions 5 of the side surface 3, the engagement of the cap 1 is performed. The engagement between the protrusion 7 and the lip 13 of the container body 11 is released from the vicinity of the two flange portions 5, and finally, the engagement between all the engagement protrusions 7 and the lip 13 is released. The This is the second stage for removing the cap 1. When the engagement between all the engaging protrusions 7 and the lips 13 is released in this way, the cap 1 is removed from the container body 11.

As described above, when a force is applied to the collar portion 5, the side surface 3 and a part of the top portion 2 are cut off, so that the cap 1 moves toward the two collar portions 5. It deform | transforms so that it may spread, and it becomes easy to cancel | release engagement with the said engaging protrusion 7 and the said lip | rip 13. FIG. Further, since there is a portion where the engagement protrusion 7 does not exist on the inner surface of the side surface 3 where the collar portion 5 is located, the engagement protrusion 7 is provided more than the case where the engagement protrusion 7 is provided on the entire inner surface of the side surface 3. It becomes easy to release the engagement between the mating protrusion 7 and the lip 13.

In this way, the cap 1 can be easily removed from the container main body 11 by lifting the collar portion 5 after pulling the knob portion 6 upward to make the tab portion notched. Can be removed. As described above, the container 10 of the present invention requires two operations to remove the cap 1. However, in the case of a container with a large mouth, if the method of removing the cap with a single action such as a maxi cap or a rimple cap is used, the contents will overflow when the cap is removed if the contents of the container are liquid or creamy. Although there is a possibility, in the container 10 using the cap 1 of the present invention, the cap 1 can be removed with peace of mind without overflowing the contents by using two operations.

After the cap 1 is removed, the container housed in the cream outer container 20 is taken out, and the container 10 filled with new cream is put into the cream outer container 20 as shown in FIG. The outer container 20 for cream is in a state where new cream is refilled. At this time, when the lid 21 is closed with the inner lid 12 attached, the state shown in FIG. The inner lid 12 can be used as an inner lid of the cream outer container 20.

Thus, the container 10 of the present invention can remove the cap 1 reliably without overflowing the contents even when liquid or the like is stored in a container having a large mouth, by using two operations. It is also possible to apply to a container having a small mouth.

The materials and the like in the present invention are not limited to those described here, and other materials can be used. Further, the shape of the collar portion 5 and the knob portion 6 are not particularly limited. In addition, since notching at least the length of the groove portion 4 beyond the center of the top portion 2 leads to easy removal, the length of the portion of the groove portion 4 beyond the center of the top portion 2 is determined as a cap. It can be determined in consideration of the ease of removal of the cap 1 according to the size and material of 1.
