Description

Fan-shaped red envelope bag device

The present invention relates to a red envelope bag, in particular to a fan-shaped red envelope bag device.

In traditional Chinese customs, there are various celebrations, such as Chinese New Year, weddings, birthday celebrations and other occasions, and red envelopes are used as congratulatory gifts. The giver will first put paper money and other gift items into the red envelope bag and present it to others, as a gift to the other party. Express congratulations.

Referring to Figure 1, a red envelope product that can be opened in a fan shape is illustrated, including a plurality of fan bars that can pivot relative to each other, a fixing member that passes through the plurality of fan bars, a plurality of adhesive sheets that are respectively arranged on the plurality of fan bars, and A plurality of red envelope bags are arranged on the plurality of adhesive sheets, and the plurality of adhesive sheets will be pasted with double-sided adhesive tape, so that the plurality of red envelope bags can be pasted on the plurality of adhesive sheets.

The plurality of fan levers can be relatively pivoted and unfolded, so that the plurality of red envelope bags are fan-shaped around the fixing member, and when the user receives the fan-openable red envelope product, he can see all the red envelopes in a fan-shaped opening bag to make the user feel happy, but the fan-shaped openable red envelope product still has the following disadvantages in actual use:

1. The red envelope bag is easy to fall off the sticker: Due to the poor viscosity of the general double-sided adhesive tape, the red envelopes attached to the sticky sheet often fall off. In addition, some red envelopes have a smooth surface to reflect light from the red envelopes. , but the red envelope bag with a smooth and shiny surface will also weaken the viscosity of the double-sided adhesive tape, resulting in the disadvantage that the conventional red envelope product that can be opened in a fan shape is easy to fall off the red envelope bag.

2. Unable to maintain the fan opening angle: The existing red envelope products that can be opened in a fan shape need to use the fixing part to fix the plurality of fan bars together so that the plurality of fan bars can pivot around the fixing part, but there is no support between the plurality of fan bars. Due to the impact structure, the pivoting opening angle between the plurality of fan bars cannot be fixed, and the fan-shaped red envelope product cannot be maintained in a fan-shaped state.

3. Additional manufacturing costs are required: The fan-shaped opening red envelope products currently on the market have multiple fan levers and fixing parts made of plastic materials, and the multiple sticky sheets will be covered with a layer of double-sided adhesive, and the multiple red envelope bags will be placed on the Multiple pasting of adhesive sheets to complete the production of the product will greatly increase the manufacturing cost of the fan-openable red envelope product.
