Description

Description PROTECTION RING FOR DRUM CLOSURE

Field of Invention

This invention is related to a protection ring for drum closures, which is interposed between the closure seat or octagonal flanges, and the upper portion of the closure or capseal that surrounds the neck portion of the opening of the drum closure and functions as a security means to avoid the possibility of counterfeiting the original contents of the drum.

Background of Invention

209 liters steel drums, that are commonly used as the containers for lubricant oil, and other liquid materials, use drum closures and capseals that are usually labeled with trade names or trademarks. The capseal itself serves as a security means to avoid the possibility of counterfeiting the original contents of the drum. However, this technique is not adequate to prevent counterfeiting of the contents inside these drums because once the capseals have been opened they can be easily replaced with duplicated capseals of similar quality. These counterfeiting of the lubricant oil not only damaging to manufacturers and consumers due to the inferior quality of the oil being traded, but also damaging to the suppliers of drum closures and capseals. These counterfeiting of lubricant oil has an adverse effect to the oil manufacturers, drum closure and capseals suppliers brought by the substantial decrease of the quantity of sales in the market for oil and capseals due to these counterfeiting of the content inside the 209 liter steel drums, that were only protected by using capseals alone.

Currently, the capseals that are used as a security to protect the content of drums is disclosed in the United States of America Patent Number US 3,122,261 with the title "Capseals for Container Closures", which was invented by Richard L. Parish, Jr. This capseal is commonly used as the outermost closure on top of the plug of the threaded drum, and also functions for marking or placing trademarks. In fact, this capseal is susceptible to counterfeiting. The counterfeiting is carried out by making a new fake capseal that is branded with a fake trademark that is identical to the original trademark on the drum, or can also be carried out by using fake trademark on both the capseal and the drum itself. The risks of this capseals duplicating by counterfeiters is very significant and in fact, has occurred quite frequently until oil manufacturers feel the urgent need for using a further security means that can reduce the risks of these unwanted duplications or counterfeiting.

Summary of Invention

The need for using a further security means to avoid capseal (closure) counterfeiting will be described in the present invention. With the existence of many capseals counterfeiting nowadays, the inventor feels concerned about this problem and has an idea to invent a protection ring, embodying flanges that are facing each other at both sides of the protection ring's body parts that can be bent or folded upwards, and the folded side may be provided with perforations that will make the folded flanges easily broken when they are pried to open, two lobes or ears are interposed between the ring flanges with protruding hole scores, where the protruded score can be matched to the ear holes of the capseals so that it can be bent and therefore holding the ear in place. In addition to this, the lower surface sides of the ring can be marked with production code, production date, batch number, lubricant manufacturer's name, trademark and distribution code, etc so as to make it easy for investigation or inspection if there are suspected counterfeiting of the contents inside the drums.

In the present invention, the capseal is coupled with the protection ring by inserting the protruded score of the protection ring into the ear holes of the capseals in the outward position from the neck of openings of the drum closure, in which, in order to open or separate the capseal from the protection ring can only be carried out by lifting the protruded score and by bending the ear holes of the capseals which will break the ears of the capseals and the protruded scores of the protection ring. Each of the ears of the protection ring will be coupled with each of the ears of the capseal and the protruded score from the protection ring inserted into the ear holes of the capseal so that the capseal can be placed precisely on top of the protection ring.

The present invention is developed by adding features at the protection ring through the existence of flanges at the two sides of the ring that are facing each other laterally from each ears. These flanges can be bent until they are called flange creases, whereas the flanges that can be bent at the ears are called protruded scores that are useful for strengthening the crimping on capseals. The flange creases are made by making several slit openings at the surface sides of the crease so as to make it easier to bend and reinforce crimping on the capseal. Aside from the protruding score of the flanges that are each facing each other, there are also four portions of flange creases that are facing one another, in which each portion of the flange crease has at least three small flange creases. Each of the flanges also has two scratches or coining/scoring, the first scratch is in-line with the circle of the base of the ring to make folding at the circle of the base easier, and the second scratch is above the first scratch and so that the flange lips will break easily whenever the flanges are being lifted in an attempt to open the capseal.

The protection ring is attached at the neck of the drum closure through the method of curling on the lips of the opening of the drum, such that the protection ring is united with the neck of the opening of the drum. At the final installation of the capseal, the protruding score of the flanges on each ears from the protection ring are bended tightly on to the capseal so that in every attempt to open the capseal, those protruding scores will have to be opened or loosened that will cause the protruded scores to tear or break. Similarly, the flange creases are tightly crimped on the capseal, and as a consequence, the flanges will be broken if they are being opened by force in an attempt to open the capseal. Another security feature is the placement of ear or lobe from the protection ring, where this ear or lobe of the protection ring is placed between the flange creases that are facing one another. The placement of the ear or lobe between the flange creases will strengthen the position of securing the protection ring with the capseal, and this will make it harder for unwanted duplications to occur since, in order to tear the capseal, it will require more than two trials of levering the flange creases, such as the levering of the flange creases that is made up of four portions of flange creases, and the levering of the protruding score of the flange on the ear or lobe of the protection ring. The placement of the ear between the flange creases will provide the drum closure with more security, more strength and make it harder for unwanted duplications to occur. The ear or lobe is also given scratches in the form of score array that are in-line with the circle of the base of the ring, which will make the ear easy to be torn or broken whenever there is an attempt to open the capseal. There is also an area provided on the lower surface of the protection ring that are visible on the flanges that can be used to attach marking or coding of product types, batch numbers, dates, manufacturer's name, brand, code and other kinds of information.

Detailed Description of Invention

Referring to Figure 1 and Figure 4, the protection ring (1) according to the present invention illustrating the ring flanges (2) in a state before they are bent or folded. A pair of ear or lobe (4) with protruding flange scores (5) that has a hole at its free end of the ear, the protruding scores functioning as an insertion to the ear hole (8) of the capseal (9) and the hole also functions as a place for inserting the pliers for the purpose of opening the capseal (not shown), line scratches (6) at the sides of the flange creases of the ring (2) is made by thinning so that when they are lifted or opened by force while in attached state, they will be torn or broken easily, therefore showing that the capseal has been opened or replaced. Figure 2 illustrates the protection ring (1) such that in Figure 1 the flanges on the ring (2) has been bent or folded to become flange creases (3) that is used to strengthen the seal between the protection ring and capseal (9) at the time when the drum closure is sealed by the capseal. And the shape of the ear from the protection ring with the protruding flange scores (5) that is in a state before they are bent to be united with the capseal. Figure 3 illustrates three parts of drum closures, namely the capseal (9), the protection ring (1) and the octagonal flange (10). The flange creases (3), where on the side portions that can be bent or folded are provided with several slit openings (14a), at least to make each sides has three parts of small flange creases (3) and the flange creases that are positioned on both sides of the ears or lobes (5) is used to ease the bending and strengthen the crimping of the flange creases to the capseal

(9) when the drum closure is sealed with the capseal.

Figure 4 illustrates the protection ring (1) that is placed between the capseal (9), which is positioned at the very top, and the closure seat or octagonal flange (10), which is positioned at the very bottom. This octagonal flange (10) is placed at the drum hole opening, by inserting it from the bottom of the drum surface (not shown). This octagonal flange (10) has an inner threading that is matched to unite with the outer thread of the threaded closure/plug (11) so that they can be sealed securely to enable the assembly of the upper portion of the washer (12), the protection ring (1), and the lower portion of the washer (13). The octagonal flange

(10) has lips (14) that are protruding upwards so as to place the octagonal flange securely to the surface of the drum closure hole opening at the surface of the drum (not shown). The capseal (9) has a pair of ears (7) with a central hole (8a) at the free end and the ear hole (8) that are to be inserted with the score of the protruding score (5) at each of the free ends of the ear or lobe (4) of the protection ring (1) until both can be sealed with the capseal securely.

Referring back to Figure 1 and Figure 2, where the important parts from this invention is the existence of these security features in the protection ring (1) that can be explained as follows. The present invention is developed by adding features on the protection ring

(1) with the existence of flanges on both sides of the ring and the placement of the ear or lobes (4) between the flange creases (3), where the ear or lobes (4) face one another laterally from each ears. These flanges (2) can be bent until they are called flange creases that functions to strengthen the seal with the capseal (9). The flange crease portion (3) is made up of several slit openings on the crease surface to ease the folding process and to strengthen the sealing with the capseal (9). The flanges

(2) and flange creases (3) are also given two scratches that are located adjoining the ear or lobes (4), i.e. the first scratch is located in-line with the circle of the base of the ring to ease the folding of the flanges on the line of the circular ring, and the second scratch is located on top of the first scratch and has a function to make the flange lips easy to break when the flange is opened by force in an attempt to open the capseal (9). These scratches are made through the process of coining with a scratch depth of 50% to 70% of the thickness of the protection ring's body. The protection ring (1) is placed on the neck of the drum closure with the process called curling towards the lips of the drum closure until the protection ring becomes united with the neck of the drum closure.

Features of this protection ring is provided by the existence of the ear or lobe that is attached to the ear lobe portion (7) of the capseal (9), where the ear or lobe (4) on the protection ring is made a protruding score (5) and the ear lobe portion (7) of the capseal (9) contains an ear hole (8) that will match each other by inserting it into the hole and crimping the protruded score (5). Where the hole from the protruding score (5) can be sealed with the ear hole (8) from the ear lobe (7) of the capseal (9) and the protruding score (5) can be folded after it is inserted into the ear hole (8) of the ear lobe (7) of the capseal (9). The other end of the ear or lobe is provided with line scratches (4a) along the sides of the ear that meets with the body of the protection ring (see Figure 3 and Figure 4). The array of scores (4a) is made through the process of perforation with a scratch depth of 50% to 70% of the thickness of the protection ring's body. Accordingly, if the ear or lobe is opened by force or is lifted, it will break at the score array (4a). Another security features from this invention exist in the ear or lobe (4) or the protection ring (1), where the ear or lobe (4) of the protection ring (1) is placed between the flange creases (3), facing one another, the placement of the ear or lobe (4) between the flange creases (3) will strengthen the bonding or crimping between the protruding score (5) of the protection ring (1) and the capseal (9), and this will make it harder for counterfeiting to occur, since in order to tear the capseal it will require more than two trials of lifting the flange creases, such as the lifting of the flange creases (3) that is made up of three portions of flange creases (3), and the lifting of the protruding flange score (5) on the ear or lobe (4). The placement mode of the ear or lobe (4) between the flange creases (3) will provide the drum closure with more security, more strength and make it harder for counterfeiting to occur.

At the final attachment of the capseal (9), the flange creases (3) of the protection ring (1) is crimped to the capseal (9) so that in order to open the capseal, these flanges must be firstly opened or loosened, which will cause these flanges (3) to tear or break. The ring body is required to be made of tin-plate or cold rolled steel/spec or aluminum with a thickness range between 0.25 mm to 0.35 mm, preferably 0.3t mm and flange thickness in the range between 0.125 mm to 0.175 mm, preferably 0.15 mm. These preferences are for the purpose of making it easy for the line scratches (6) to break when the flanges (2) are opened or lifted. Before the flanges (2) from the protection ring (1) are given line-scratches at the sides that can be folded along the boundary line of upright side of the ring body, they will firstly be flattened, so that the flanges (2) will be thinner than the ring body. This method is also carried out in a similar way when forming the line scratches (6) of the ear or lobe (4) of the ring.

Previous explanations from this invention have been presented for the purpose of illustration and clear explanations. Of course, it must be understood that anything that was described by referring to the Figures according to this invention is not only exclusively limited to what has been described.
