Description

Manufacturing method for setting imprint on can tab

technical field

The invention relates to a method for manufacturing a jar, in particular to a method for manufacturing the uppermost top of the jar. Specifically, the present invention relates to a method of manufacturing a jar top tab, including imprinting an imprint, such as a logo, on the jar tab; for promotional and decorative purposes, proof of purchase, authenticity of the product, and others.

technical background

Traditionally, printing, embossing, etching or marking have been used to create an imprint on the top tab of the jar to provide information, advertising or decoration. In fact, any conventional technique may provide markings for the tab at the top of the jar, which may include, but is not limited to, ink, paint, silk screens, sticky or glue. Later, laser technology was also used to create the imprint on the top tab of the can.

The term "stamping" referred to in the specification includes all markings of any kind provided on the tab. This includes inscriptions, letters, numbers, symbols, drawings and topographical depictions on the Griph. And "hook the tab to open", "solve it properly", "don't litter" and other short messages are the earliest visible imprints on the tab. Since then, some more creative, colorful or decorative imprints have been used as attractions, promotions, trademarks, shopping evidence, authenticity of products, and messages to prevent damage and so on.

In the prior art (US6082030) those molded plastic caps were used as a validation system. However, such a confirmation system is very expensive, since the technique used requires an additional piece of plastic material to be inserted inside the tab.

In the prior art (US6105806), a laser device was used to burn or etch tabs that had been anodized or coated with a layer of aluminum. Here, the can top tab must be made of various aluminum materials to create a colored logo or decoration, and the materials used to produce the logo or decoration, its procedures and installation costs are quite expensive .

While in the prior art (WO0228730), the logo or the sticker used for decoration is pasted on the tab by a device for attaching the label. However, the logos produced by this technique are not durable due to the nature of the labels.

The present invention successfully overcomes the limitations of all previous systems. Because one of purposes of the present invention is in order to reduce the expense that sign or font are placed on the pull ring. In fact, the cost of engraving a pre-formed logo pattern through the tab is much less than the cost of using laser equipment.

Another object of the present invention is to reduce the time required to install the logo on the tab. For example, if the engraving process is used to engrave the logo on the tab, the time taken will be very short. This procedure will directly reduce the working hours of labor, reduce the cost of hiring labor, and increase production.

Still another object of the present invention is to allow signs to last longer than those produced by other techniques.

Summary of the invention

In order to achieve the above purpose, the present invention has created a method for manufacturing the stamp on the metal tab on the top of the metal can, including how to emboss the stamp on the tab.

Most suitably, the method of imprinting on the jar includes printing, molding, embossing, engraving, embossing, debossing any of which may be formed by any combination of the following, which includes text, numbers, symbols, drawings and geographies Chi's depiction can be placed on the pull ring. And these marks can be made into the shape with holes on the pull ring, and part of the pull ring is engraved and cut off to form an imprint.

Generally, the pull ring is made of metal sheet, and the imprint can be printed on the pull ring so that the imprint can appear on the upper and lower parts of the metal sheet. It is also possible to imprint in general on the sheet metal at suitable distances and then make tabs on each imprint. Alternatively, the imprint and tab can also be pressed together on the same metal sheet at the same time to form a tab with an imprint.

It is added that this method further includes folding the sharp edge of the tab to form a rounded edge.

In another aspect, the present invention provides a method for making an easily opened jar lid having a stamped tab, and the invention comprises the following steps:

- Manufacturing pull rings

-Press the imprint on the tab

- Fitting the imprinted tab on the jar lid, including fastening the tab and jar lid together with rivets.

The step of installing the imprinted pull ring on the jar lid actually includes how to remove the imprinted pull ring from the metal sheet, and then fasten the pull ring and the jar lid tightly with rivets. Furthermore, it is also possible to fold the sharp edge of the manufactured tab to form a rounded edge.

Beyond that, the next step is to draw a cut line on the top lid of the jar and snap the stamped tab somewhere inside the cut line on the jar lid. The advantage is that when we lift the ring, the part drawn with the cutting line will be easily pulled together with the ring, and the whole piece will be pulled apart. The mentioned cut lines can be drawn on a small portion of the lid or on the entire lid, around the edge of the jar.

Alternatively, the tab and can end may be assembled in one continuous manufacturing process to produce a can end with the tab already attached.

Detailed ways

Please refer to the accompanying drawings and the following detailed description for a better understanding of the present invention on how to make a stamp or lettering (such as engraving, printing, such as stamping in the metal industry in mechanical engineering) on the tab of the jar.

Fig. 1 is a jar top (1) with a tab (10) for printing logos. The jar top (1) has a pull tab (10) fastened to the jar top (1) by rivets (14) or any conventional means and a tear strip (13) on which a cut line (18) has been drawn. Tear strip (13) can be torn under hard. That pull ring (10) is actually made of a grip (12) and a fixed part (11). The pull ring (10) is firmly fastened to the top (1) of the jar by the rivet (14), and at the same time, the fixed part (11) of the pull ring (10) is also connected by the pull ring to the rivet (15) to become a lever . And the pull ring (10) regards the rivet (14) as the central point, once the grip (12) is hooked up, it will be combined with the fulcrum of the lever to produce a leverage effect, allowing the fixed part of the pull ring (10) to (11) produce the power that pulls down around rivet (14), and like this, tear bar (13) will be pushed away downwards. Tear strip (13) is through specific design, and when it is pushed away, a part of tear strip (13) will be opened but the tear strip that also has a part is still also connected with cutting line (18), keeps At the top of the jar (1), until the tear strip (13) is completely pushed away, the mouth of the jar will appear, allowing consumers to eat the food in the jar. Metallic materials are most suitable for manufacturing the tab (10), such as aluminium, aluminum alloy, steel or zinc or any other suitable material etc. These metals have also caused the tab (10) to be pressed out of the sheet metal with different pressing methods. In fact, the metal materials mentioned above can allow the machine to easily engrave the required logo through the pull ring (10). Including all kinds of signs such as: fonts, images, trademarks, etc. can be printed on the pull ring (10) to be used for making publicity. In addition, the method of printing the sign (16) on the pull ring (10) also replaces the previous method of just opening a hole in the pull ring (10) to form a pull ring.

Fig. 2 is about the second manufacturing method of the present invention. In this manufacturing method, the pull ring (10) that will be mentioned is the same as the structure of the pull ring (10) of the above-mentioned first manufacturing method, and is also fastened on the top of the jar by the rivet (24) in the same way (21), but the different place is tearing strip (23). In fact, the tear strip (23) of this one is formed by the entire top of the jar (21) and then a cut line (28) is drawn around the edge of the jar so that when the tab (10) is pulled up, the top of the jar (21) was also torn apart.

The present invention can utilize a kind of pressing device to manufacture required pull ring (10), as seen from Fig. 3; After embossing, sign will be printed pull ring (10). At first, use the first method to print the pull ring (10) with the logo; that is, put a strip of steel or aluminum sheet into the shaped part (S31), and then make a predetermined shape of the pull ring on the steel or aluminum sheet, then is a pull ring not yet marked on the grip (12). Afterwards, the metal sheet with the shape of the tab printed will be put into the printing part (S32), and then the desired logo will be printed with equipment. Next, it will leave the engraved part (S32), and then the next stop is to install the rivets (S33). Here, the tab will be separated from the steel or aluminum sheet (S34) and fastened to the top of the can with rivets (21). Perhaps those who are more technical will add an additional fold (S35) that rounds the sharp edge of the tab to enhance the feature of the tab. However, this folding part (S35) can be interchanged with the order of the two parts mentioned above.

Fig. 4 has shown another kind of method of manufacturing tab (10), and that is to use pressing method to manufacture the tab (10) that has printed mark. This second method is different from the previous ones, that is because this method first proceeds to the printing part (S41) and then enters the sizing part (S42). First, the required logo will be printed on a steel or aluminum sheet with a pre-measured distance (S41), and then it will enter the shaping part (S42) to manufacture the tab. The mark directly printed on the pull ring (10) will be more durable. Next, the tabs that have been made will be firmly fastened to the top of the jar by rivets.

In addition, the present invention can also use steel or aluminum materials with different colors to manufacture pull rings with colors and logos.

The present invention is not limited to the above stated, only structural properties, but the present invention may also exhibit its functions with other characteristics or production structures. However, in any case, all known or modified concepts similar to those disclosed in the present invention will be included within the scope of the present invention.
