1. Field of the Invention
The present invention relates to a cardboard template and a paper wallet, and more particularly to a cardboard template being foldable to make multiple interlayers of a paper wallet and a paper wallet as well as to a paper wallet made of the foldable cardboard template.
2. Description of the Related Art
Wallets are useful in storing money, personal identification, credit cards, debit cards and the like, and are made of materials such as cloth, plastic, leather and so forth. Based on the usages and the appearances of the wallets, many manufacturing processes, such as cutting, sewing and the like, are involved to produce the wallets. Especially for wallets having multiple interlayers, more time-consuming and complicated manufacturing techniques are needed to deliver the wallets. The wallets having poor design may become heavy and thick, result in the low yield rate, are easily worn out or broken at the seams of the wallets, and lead to a high rate of damage.
An objective of the present invention is to provide a foldable cardboard template being integrally formed, easily produced, environmentally friendly and durable.
To achieve the foregoing objective, the foldable cardboard template has an outer panel, multiple binding strips and an interlayer board.
The outer panel is rectangular and has an inner surface, two longitudinal sides, two transverse sides and a center fold line.
The center fold line is centrally formed on the outer panel and is parallel with the transverse sides.
The binding strips are respectively formed on and protrude from one of the longitudinal sides and the transverse sides of the outer panel.
The interlayer board is ladder-like, is formed on and transversely protrudes from the other longitudinal side of the outer panel having no binding strip formed thereon, and has multiple interlayers and multiple partition lines. The interlayers are connected with each other. Each partition line is formed between adjacent two of the interlayers.
Preferably, the binding strips are trapezoidal.
Preferably, the foldable cardboard template has four binding strips, two of the binding strips are respectively formed on and protrude from the transverse sides of the outer panel, and the other two binding strips are respectively formed on and protrude from the longitudinal sides of the outer panel and are symmetrical with respect to the center fold line of the outer panel.
Preferably, the interlayer board is divided into five interlayers, each interlayer is rectangular and has a longitudinal side adjoining that of an adjacent interlayer, the interlayers of the interlayer board are transversely connected, and each interlayer has a partition line longitudinally and the partition lines of the interlayers gradually decrease in length in a direction away from the outer panel.
Preferably, the interlayer board has multiple card slits formed through a portion of the interlayer board away from the outer panel.
As the foldable cardboard template is integrally formed and structurally simple, a paper wallet made of the foldable cardboard template can be produced by folding the cardboard template and affixing the cardboard template to the outer panel. Accordingly, the production of the foldable cardboard template and the resulting paper wallet is simplified and easy for recycling and is environmentally friendly.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
With reference to
In the present embodiment, the interlayer board 40 has four partition lines 41. The interlayer board 40 is sequentially divided into a first interlayer 42, a second interlayer 43, a third interlayer 44, a fourth interlayer 45 and a fifth interlayer 46 in a direction away from the outer panel 20. Each of the first, second, third, fourth and fifth interlayers 42, 43, 44, 45, 46 has a pocket surface that is on the opposite side to the inner surface of the outer panel 20. The pocket surfaces of the first and the second interlayers 42, 43 and of the third and the fourth interlayers 44, 45 respectively form two interlayer compartments. The longitudinal sides of the first, second, third, fourth and fifth interlayers 42, 43, 44, 45, 46 gradually decrease in length in a direction away from the outer panel 20. The fifth interlayer 46 or the third interlayer 44 is folded at a corresponding partition line 41 so that the pocket surface of the fifth interlayer 46 or the third interlayer 44 leans toward a surface of the fourth interlayer 45 or the second interlayer 43 opposite to the pocket surface of the fourth interlayer 45 or the second interlayer 43. The first interlayer 42 is folded at the connected longitudinal side of the outer panel 20 so that the pocket surface of the first interlayer 42 leans toward the inner surface of the outer panel 20. The fourth interlayer 45 or the second interlayer 43 is folded at a corresponding partition line 41 so that a surface of the fourth interlayer 45 or the second interlayer 43 that is opposite to the pocket surface of the fourth interlayer 45 or the second interlayer 43 leans toward the pocket surface of the third interlayer 44 or the first interlayer 42. The pocket surface of the fifth interlayer 46 faces outwardly after the interlayer board 40 is folded and flatly stacked on the inner surface of the outer panel 20.
After the interlayer board 40 is folded and flatly stacked on the inner surface of the outer panel 20, the binding strips 30 respectively extending from the transverse sides and the longitudinal sides of the outer panel 20 are affixed between the pocket surfaces of the fourth interlayer 45 and the fifth interlayer 46 on the outer panel 20 to securely fix the foldable cardboard template 10 . The pockets 25 are formed between corresponding interlayers. The card slits 401 formed through the fifth interlayer 45 and located on both sides of the center fold line 21 serve for insertion of cards. The folded interlayer board 40 and the outer panel 20 are further folded at the center fold line 21 with the card slits 401 facing each other to form a paper wallet.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
