Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a cap for sealing the caps of drums and the like.

(Prior art) This type of sealing cap is well known as shown in the invention of Utility Model Publication No. 31159 of 1973, and the one intended for sealing bottles outside drums and aluminum containers is the There are ideas such as No. 31236 and No. 51-32754.

(Technical Problem) However, the conventional seals used to seal the caps of drums have had the problem of being difficult to open even with pliers or other tools. This is because the sealing material is thick and sturdy. By the way, in recent years drum cans have become thinner and can no longer be stacked horizontally, and it has become necessary to stack them vertically. As a result, water tends to accumulate in the lid, and it has been pointed out that water can get inside when the lid is opened.

The purpose of this invention is to solve the above problems, and its purpose is to create a cap that is easy to open without the use of tools such as pliers, and that prevents water from accumulating on the top surface even when stacked like drums. It is about providing.

(Technical Means) The purpose is to form a tear strip 4 bounded by two thinned break lines 3 in the diametrical direction of a cap body 2 made of thin plate material that seals a lid 1 applied to a cap;
A pull ring 5 protruding from the cap body 2 is provided at one end of the tear strip 4, and a step 6 is added to the boundary break line 3 so that the portion where the tear strip 4 is provided is higher than the other portions. can be achieved.

That is, the tear strip 4 breaks the cap body 2 and opens the cap body 2.
The thinned break line 3 is a means to facilitate the break, but this break line 3
is formed thin by providing a step 6 on the main body 2. This method eliminates the need for the conventional step of cutting the thickness of the material to provide a break line, and also reduces the decrease in strength compared to the case of grinding. Furthermore, the step can also serve as a means for positioning the tear strip 4 portion higher than other portions.

(Function of the invention) The cap of the present invention has a tearing strip 4 in the diametrical direction of the main body 2, and the boundary between the strips is thinned, so that when opening the cap, it is easy to pull the cap by holding the pull ring 5 at the end of the strip. The thin breaking line 3 allows the cap to be opened so as to divide the cap into two parts, and since the opening zone 4 is higher than the other main body parts and has a step 6 at the boundary, it tends to protrude and water easily drips off.

(Embodiment) The illustrated embodiment shows a cap for sealing a lid 1 applied to a mouthpiece d of a drum can D. The cap body 2 is formed from a top plate part 7 and a skirt part 8 in order to completely cover the lid 1. The top plate 7 is provided with a tapered opening strip 4 defined by two breaking lines 3, 3 that cross approximately the center. The main body 2 of the embodiment is made of a thin metal plate, and the opening band 4 has a step at the boundary with the other top plate part 7 and is higher than other parts, and has a thinner breaking line 3, 3 at the boundary. The skirt part 8 is formed by press molding, and a pull ring 5 integral with the opening band 4 is provided to protrude from the lower end of the skirt part 8. At the end, the connection is maintained when opening. 3a is a notch for starting cutting formed at the base end of the tear strip. The material of the main body is not limited to metal, and may be made of resin or a combination of metal and resin. Reference numeral 9 indicates a step of the skirt portion 8, and reference numeral 10 indicates a ventilation hole.

(Effect of the invention) Therefore, when the cap is sealed, the opening band 4 is torn along the break line 3 by pulling up the pull ring 5 and tearing it toward the end, so there is no need to use tools as in the conventional case. It can be opened extremely easily with just your fingertips. In addition, since the tear strip 4 protrudes from other parts, water will not accumulate on the top surface of the cap main body 2 even if the cap is stored upright and stored in the open. This can prevent water from getting inside. In particular, in the case of the present invention, two thinned break lines 3, 3 and a stepped portion 6 are formed at the boundary when the tear strip 4 is made by press molding, so that manufacturing is facilitated and the entire cap is sealed. It has the characteristic that the strength in the direction perpendicular to the step increases without any decrease in strength.
