Description

[Detailed description of the invention] This invention enables accurate and easy alignment of the spout opening protrusion provided on the lower side of the top plate of the can cover and the spout provided on the top plate of the can. The present invention relates to a lid for a can with a pouring spout, which is intended to prevent the lid from blocking and to prevent accidental opening.

Previously, the applicant proposed a can body lid with a spout that opens when pressed, and a protrusion on the bottom surface for pressing down the spout (for example, Japanese Utility Model Publication No. 56-51484).
issue).

However, in the above conventional technology, no consideration was given to alignment between the protrusion and the spout.
There are problems in that it takes time to align the two, and if the protrusion is pressed before the two are aligned accurately, more force than necessary is required to open the opening.

Furthermore, conventional lids may block when stacked, which hinders automatic feeding, and no effective means for preventing accidental opening has been known.

However, in this invention, the cover is made transparent or semi-transparent, and a mark is provided on the top plate to make the opening protrusion face the spout of the can, so by using the mark as a reference, it is possible to accurately and easily It is now possible to align the protrusion and spout, and a support protrusion for preventing blocking is provided on the underside of the top plate, making it possible to prevent blocking as well as accidental opening. , which solves the above-mentioned conventional problems.

This invention will be explained below based on the embodiments shown in FIGS. 1 to 5.

On the bottom side of the top plate 2 of the cover lid 1 of a can made of transparent synthetic resin (for example, polyethylene) molded into a cap shape, scores 5 are provided in an incomplete annular manner on one side of the top plate 4 of the can body 3. Separation piece 5
A protrusion 6 for opening the spout formed by a and a is integrally molded.

The protrusion 6 has a semicircular bottom surface, an arcuate edge thereof protrudes downward, and a tip 6a thereof is sharp.
And it protrudes at a position corresponding to the score 5 of the spout.

In the figure, numeral 7 denotes a bar-shaped bar-shaped projection protruding from the lower surface of the top plate 2, and is provided at a position corresponding to the incomplete portion of the score 5.

The return projection 7 and the projection 6 constitute an opening projection.

Further, on the other side of the lower surface of the top plate 2 of the cover lid, a protrusion 8 having sharp ends at both ends is provided diametrically on the other side of the top plate 2 as a mark for making the protrusion and the spout face each other. can top plate 4
When the reference line (for example, a thin line) 9 shown in 2 is superimposed, the protrusion of the cover 1 and the spout are accurately opposed to each other.

8a is a mark to draw attention to the protrusion 8.

In the figure, reference numeral 10 denotes a support projection protruding from the lower surface of the top plate of the cover lid 1, which prevents the upper and lower covers from fitting or interlocking with each other (blocking) when a plurality of cover lids 1 are stacked. (If multiple lids block, it becomes difficult to supply each lid to the can body one by one.)

The cover 1 shown in the above embodiment is used by covering the can body 3, but when opening the spout, the cover 1 is rotated and the protrusion 8 is placed on the top plate of the can body 3. When superimposed on the provided reference line 9, the opening protrusion corresponds precisely to the spout.

When the corresponding portion 6b of the upper surface of the covering M1 is pressurized and the protrusion 6 is pushed down (as shown by the chain line in FIG. 5), the score 5 is cut off by the tip 6a of the protrusion 6.

When the protrusion 6 is further pushed down, the separation piece 5a is bent toward the inside of the can body 3, and the spout is opened.

According to the above embodiment, since the barbed protrusion 7 is provided corresponding to the incomplete part of the score 5, when the barbed protrusion 7 is inserted into the pouring spout, the cutout piece 5a is almost cut out along the barbed protrusion 7. It can be bent at right angles and the spout can be opened wide.

Here, since the protrusion 6 and the return protrusion 7 are made independent, the range of free movement of both protrusions is relatively wide.

Therefore, the score can be easily torn by the protrusion 6, and the return protrusion 7 can be moved deep into the can, so that the tearing piece 5a can be easily bent at right angles.

Furthermore, since the support protrusion 10 is provided, even when a plurality of lids are stacked, it is possible to smoothly and automatically supply the caps without the risk of blocking, and after the lids are attached to the can, the support protrusion 10 disperses and supports the external force. Therefore, the entire external force is not applied to the opening protrusion.

As a result, accidental opening can be prevented.

Next, in the embodiments shown in FIGS. 6 and 8, the top plate 2 of the cover 1 is
An annular protrusion 11 is provided on the lower side of the can body 3 in correspondence with the score 5 of the can body 3, and one side of the protrusion 11 is made to protrude downward, and its tip 11a is sharpened for opening. In addition to forming a protrusion, a groove 12 is provided as a mark on the upper surface of the other side of the top plate 2.

In the figure, reference numeral 13 denotes a blocking prevention protrusion provided in an arc shape on the peripheral edge of the lower surface of the top plate 2.

After the cover 1 shown in the above embodiment is covered with the can body 3,
By overlapping the groove 12 with the reference line (for example, a protrusion) 9 of the top plate 4, the opening protrusion and the opening can be accurately aligned.

Also in the above embodiment, when the protrusion 11 is inserted into the spout, the top plate of the spout part follows the outer wall on one side of the protrusion 11.
It is bent at a right angle to the inside of the can body.

In the above embodiment, the protrusion 8 or the groove 12 is used as the mark.
However, in addition to protrusions or grooves, marks may also be provided by carving or printing fine lines.In short, the marks should be aligned with the reference lines provided on the top plate of the can body and aligned with the protrusions on the cover lid 1. It is only necessary that the spout be accurately opposed to the spout.

Further, the installation position is not limited to the above-mentioned embodiments, and may be provided tangentially to the opening, as shown in FIG. 7, for example.

It is easier to align the marks if they are shorter than the reference line on the top plate.

Further, the cover may be made of a transparent material, as long as the overlap between the reference line of the top plate and the mark can be visually confirmed.

In other words, according to this invention, a mark is provided on the top plate of the transparent or semi-transparent cover lid to ensure that the protrusion for opening the spout is accurately opposed to the spout, so it is possible to accurately and easily use the mark as a reference. This has effects such as being able to align the protrusion and the spout.

Further, since the support protrusion for preventing blocking is provided, blocking is prevented and openings due to unexpected external forces can be prevented.
