Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lid that is externally fitted to a flange of a container body.

[0002]

[Prior art]

 In this type of fitting container, the elasticity of the lid is used to press-fit the skirt portion of the lid around the opening of the container body to seal the opening and simultaneously hold the lid.

[0003]

[Challenges of device]

 Since the skirt portion of the lid and the container body are tightly fitted to each other in this manner, it is difficult and troublesome to remove the lid.

Therefore, a method in which a tab is provided on the skirt portion of the lid and the tab is used as a clue to pry open is widely adopted.

However, the fact is that the lid cannot be easily removed even with such a tab.

Therefore, an object of the present invention is to enable the outer fitting lid to be removed with one action.

[0007]

[Means for solving the problem]

 In order to solve the above-mentioned problems, the outer fitting lid of the present invention is provided with a top wall and a skirt portion hanging down from the peripheral edge thereof, and a pair of notches adjacent to the curved portion of the skirt portion at short intervals. , The top wall near the line connecting the notches was made almost flush with the upper edge of the skirt. Further, a tab may be formed on the lower edge of the skirt portion corresponding to this portion.

[0008]

[Action]

 If the notch is formed so that the upper edge of the notch is as close as possible to the upper edge of the skirt, the top wall of the lid is almost flush with the upper edge of the skirt near the line connecting the notches. At the upper end of the sheet, the thickness becomes closer to the thickness of the sheet that forms the lid, and the lid easily bends when the skirt corresponding to this section is pulled up. As a starting point, the entire fitting can be easily released.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 4, a lid 1 of the present invention comprises a top wall 2 and a skirt portion 3 hanging down from the outer periphery thereof, and the top wall 2 has a bulging portion which is raised higher. 4 is provided, and a pair of notches 6 a and 6 b are provided in the skirt portion 3 adjacent to one corner portion 5. It is preferable that the tips of the notches 6a and 6b be brought as close as possible to the upper edge of the skirt portion 3, but if they are brought too close to each other, a crack will occur when the lid 1 is fitted or removed, and the notch 6a, 6b will be apex. Proper spacing is necessary as it may reach the wall 2.

Further, the distance between the pair of notches 6a and 6b varies depending on the size and shape of the lid 1 corresponding to the container body. make it easier.

Next, the top wall 2 a outside the line 7 that connects the notches 6 a and 6 b is substantially flush with the upper edge of the skirt portion 3. Therefore, the bulging portion 4 does not exist in this portion. A tab 8 is provided on the outer circumference of the skirt portion 3 corresponding to the top wall 2a. It is also possible to omit this tab 8.

As shown in FIG. 5, a lid without the bulging portion 4 may be used. In that case, it is not necessary to particularly provide a portion corresponding to the top wall 2a. This is because the entire top wall 2 is substantially flush with the upper edge of the skirt portion 3. Further, the same applies to the case where the bulging portion 4 is small as shown by the chain line in FIG. In addition, a device having a groove between the bulged portions 4 and 4a is also included in the present invention.

The planar shape of the lid 1 is not limited to the illustrated quadrangle. It can take any shape, such as other polygons or circles. In the case of a polygon, a pair of notches may be formed in the skirt by sandwiching the corners in the same manner as in the above-mentioned embodiment, and in the case of a circle, the notches may be provided at any two relatively close points. It is good to provide. Of course, in any shape, the notch and the tab can be provided at two or more places.

FIG. 6 shows a state in which the lid 1 is externally fitted to the flange 11 of the container body 10. Since this figure is a vertical cross-section on a diagonal line, the top wall 2a and the tab 8 often appear. Now, when the tab 8 is raised in the direction of the arrow, the tips of the notches 6a and 6b are removed as shown in FIG. Since the portion of the top wall 2a is easily bent by the connecting line, the fitting is disengaged like a chain line, and this serves as a starting point to easily remove the lid 1.

[0016]

【effect】

 According to this invention, as described above, a pair of notches are provided in the skirt portion of the lid at relatively close intervals, and the top wall near the line connecting the notches is made substantially flush with the upper edge of the skirt portion. Since the top wall of the lid easily bends along the above line, it is possible to easily remove the fitting by raising the skirt portion corresponding to this portion, and thus the lid can be easily removed. Can be done.
