JPS5910047Y2 - Synthetic resin partition plate with pressure piece - Google Patents

Description

[Detailed Description of the Invention] This invention relates to a synthetic resin partition plate with a pressure piece for the purpose of facilitating opening of the synthetic resin partition plate.

Conventionally, a structure is known in which a partition made of a plywood board is provided in the can opening to seal it, but in order to open this, it is necessary to cut it with a separate knife, or to cut it with a cutout groove in advance. It is known that the opening can be opened by pulling a tab that is fixed to a board, but in a method that uses a separate knife, the knife must be packaged separately, which only makes packaging and use more inconvenient. However, cutting requires some skill,
In the method of pre-preparing cutting grooves on the partition plate and pulling the tabs to cut them, not only is there a restriction on the material of the partition plate, but if the cutting grooves are shallow, cutting becomes difficult, and the cutting grooves become too shallow. If the depth is too deep, there are problems such as loss of sealing performance.

However, according to this invention, a cutout groove is provided in the partition plate and a pressure piece is attached, so that the cutout groove part is cut under pressure by the end of the pressure piece, and the cutout groove is relatively shallow or the material of the partition plate is strong. Even if there is, the above-mentioned conventional problems have been solved by making it easy to cut.

That is, to explain this invention with reference to the embodiment shown in FIGS. 1 to 3, there is a ring shape on the outer periphery for fixing to the upper edge of the can rolling ring 1a (the same applies to the upper edge of the can body), which is connected to the can body 1. An inner partition plate 6 is constituted by a polyethylene disc 4 having a projecting edge 2 and a cutting groove 3 on the lower surface opposite to the inner circumferential base of the annular projecting edge 2, and one side of the intermediate partition plate 6. A small cylindrical column 5 is provided protruding from the upper part, and a mounting hole 8 for a knob 7 is fitted into the small cylindrical column 5. The knob 7 has an arcuate side surface, and its tip 7a faces above the cut groove 3. , the base end 7b is inclined upward to make it easier to pick up.

For example, the knob piece of this embodiment is moved to one corner as much as possible as shown by the chain line in FIG. 3. When lifted as shown in Figure 3, combined with pressure on the tip of the knob, the section can be cut and opened very easily.

Therefore, if the knob is pulled in the direction of arrow 9, the partition plate 6 will be easily broken through the cutout groove, and the partition plate 6 can be removed.

In the above embodiment, the partition plate was made of polyethylene, but it is not limited to this resin.

That is, according to this invention, a knob is attached to the partition plate, and a part of the knob is used to pressurize the cutting groove, so even if the cutting groove is shallow or relatively strong resin is used, it can be easily cut. There is an effect that can be done.

It should be noted that once a portion of the resin is cut, it is relatively easy to cut the cut end, so it is particularly effective to use a pick piece for initial cutting.

As you can see from its usage, the purpose of the knob piece can be achieved by simply fitting it into the small cylinder without having to attach it to the partition plate.

Since the base end of the knob is inclined upward, it is easy to pick and it is easy to apply a strong force to the knob.

In addition, since the knob piece has a side arc shape, it is strong and can be easily cut even when the cutting groove of the partition plate is shallow or relatively strong plywood resin is used.
