Description

Product sales server and product sales system

The present invention relates to a resale system for products purchased through a lottery.

　Traditionally, a transaction would involve a customer purchasing a product that was packaged so that the product's contents could not be determined from the outside, and then opening the package to check what product they had purchased. In that the product is purchased without knowing the contents, the packaged product can also be considered a transaction involving a lottery.

However, in a buying and selling system that uses packaged products or a lottery process like that described in Patent Document 1, a purchaser may end up buying or winning products that they do not need, and as a result of being unable to dispose of the products, the purchaser may end up discarding the unwanted products.

The present invention was made in consideration of the above situation, and its purpose is to enable effective use of the product that a purchaser acquires as a result of a lottery purchase, even if the purchaser no longer needs the product.

The first aspect of the present invention is a product sales server that includes a lottery sales control unit that receives a request to purchase a product via a lottery action, and a resale control unit that receives a request to resell the product purchased via the lottery action.

Preferably, the item purchased via the lottery action is an item allocated depending on the outcome of a lottery operation.
Preferably, the product sales server is managed by a first business operator, and the product sales server further includes a shipping control unit that accepts a shipping request for the product purchased through the lottery action, and the shipping control unit accepts the shipping request for the product from a server managed by a second business operator separate from the first business operator.

The second aspect of the present invention is a product sales system including the product sales server, in which the product sales server is communicatively connected to a lottery operation terminal that purchases products from the product sales server through a lottery action, and a resale purchase terminal that purchases resold products from the products purchased by the lottery operation terminal through the lottery action.

The present invention allows for effective use of products acquired through lottery purchases even when the purchaser no longer needs the product.

Below, an embodiment of the present invention will be described with reference to the drawings. The same reference numerals will be used throughout the drawings to refer to the same parts, and duplicate explanations will be omitted.

FIG. 1 is a diagram showing an overview of a commercial transaction that applies the lottery product resale system according to this embodiment.

In Figure 1, the first site operating company 2 is the management company of the lottery product resale system 100 (see Figure 2).

In this embodiment, a product holder 1 such as a manufacturer or wholesaler delivers products to a first lottery sales site operating company (hereinafter abbreviated as "first site operating company") 2. The products are brought into a product management department (direct sales store, warehouse, etc.) 3 managed by the first site operating company 2 (S1). The first site operating company 2 uploads the delivered products to a website accessible by the product holder 1 (S2). The product holder 1 can confirm on the website that the products have been delivered to the product management department 3.

1 illustrates an example of a "product" that is a tangible object brought into the product management unit 3, but the "product" in this embodiment may also be an intangible product such as digital data. In that case, a storage device managed and accessed by the first site operating company 2 may be used in place of the product management unit 3. Tangible products may be of any type, such as game media such as trading cards printed on paper, clothing, food, alcohol, and fitness equipment. Intangible products may also be game item data used in online games and NFT data (Non-Fungible Token).

There may be multiple product holders 1.

The first site operating company 2 is the company that mainly manages and operates the lottery product resale system 100 (see Figure 2), and also operates the lottery sales site 21 and the resale site 22.

The lottery sales site 21 is a site that sells products delivered through a lottery process. For example, the product holder 1 may prepare a package filled with one or more products stored in the product management unit 3 and offer the package as a single sales unit on the lottery sales site 21, or may specify a product to be won in a so-called gacha.

The lottery purchase user 4 accesses the lottery sales site 21 (S3) and enters the lottery. The lottery purchase user 4 pays a fee, enters the lottery operation, and the winning product is determined. This means that the lottery product has been purchased (S4). After that, the product is temporarily stored in the product management unit 3, and ownership is transferred to the lottery purchase user 4. In this embodiment, the act of transferring ownership of the product to oneself without moving it from the product management unit 3 is referred to as "adding it to (one's) collection."

If the lottery purchase user 4 does not need any of the lottery products he or she purchased, the user puts the unwanted items up for sale on the resale site 22 (S5).

The resale product purchasing user 5 accesses the resale site 22 (S6) and purchases the item if they like it (S7). The resale product is then added to the resale product purchasing user 5's collection. The reprint product purchasing user 5 may list further resale products in their collection or request that they be shipped to the resale product purchasing user 5 (S8).

The second lottery sales site operating company (hereafter abbreviated as "second site operating company") 6 is a separate business entity from the first site operating company 2, and is the first manufacturer of this lottery product resale system 100 (see Figure 2), and operates the lottery sales site 61D under a contract with the first site operating company 2.

The lottery sales site 61D is a site that sells products delivered through a lottery process. For example, the second site operating company 6 may prepare a package filled with one or more products stored in the company and offer the package as one sales unit on the lottery sales site 61D, or may specify a product to be won in a so-called gacha.

The lottery purchase user 7 accesses the lottery sales site 61D (S9) and enters the lottery. The lottery purchase user 7 pays a fee and enters the lottery to determine the winning product. This results in the lottery purchase user 7 purchasing the lottery product (S10). After that, the product is temporarily stored in the product management department of the second site operating company 6, and ownership is transferred to the lottery purchase user 7.

If the lottery purchase user 7 does not need any of the lottery products he or she has purchased, the user puts the unwanted items up for sale on the resale site 22 of the first site operating company 2 (S11).

Resale product purchasing user 5 can access the resale site 22 and purchase items listed by lottery purchasing user 7. When resale product purchasing user 5 purchases an item listed by lottery purchasing user 7, the resale product is added to the collection of resale product purchasing user 5. Reprint product purchasing user 5 may list further resale products in his/her collection, or request shipping to resale product purchasing user 5.

When a lottery purchase user 7 or a resale product purchase user 5 requests the shipment of a product sold by the second site operating company 6, the second site operating company 6 delivers the product to the first site operating company 2. The product delivered to the first site operating company 2 is brought into the product management department (direct sales store, warehouse, etc.) 3 managed by the first site operating company 2 (S12). After this, the first site operating company 2 ships the product delivered by the second site operating company 6 to the lottery purchase user 7 or the resale product purchase user 5.

Figure 2 shows the system configuration of the lottery product resale system.

The lottery product resale system 100 is composed of a lottery resale server 10 operated by a first site operating company 2, a lottery server 11 operated by a second site operating company 6, a lottery server 12 operated by a third lottery sales site operating company, a lottery server 13 operated by a fourth lottery sales site operating company, a lottery operation terminal 20 operated by a lottery purchasing user 4, and a resale purchase terminal 30 operated by a resale product purchasing user 5, all of which are connected to each other via a network 40 for communication.

FIG. 3 is an explanatory diagram showing the connection of the sites of the lottery product resale system 100 (see FIG. 2).
In FIG. 3, departments 2-1 and 2-2 of the first lottery sales site operating company correspond to the respective departments of the first site operating company 2 shown in FIG.

In FIG. 3, department 2-1 of the first lottery sales site operating company operates three lottery sales sites: lottery sales site 21A, lottery sales site 21B, and lottery sales site 21C. Lottery sales site 21A, lottery sales site 21B, and lottery sales site 21C refer to lottery sales site 21 shown in FIG. 1.

In FIG. 3, the department (market) 2-2 of the first lottery sales site operating company is the market of the first site operating company 2, and department 2-2 operates the resale site 22 shown in FIG. 1.

In FIG. 3, the second site operating company 6 is a separate business entity from the first site operating company 2, and is the first manufacturer of the lottery product resale system 100 (see FIG. 2), and operates the lottery sales site 61D under a contract with the first site operating company 2.

The third lottery sales site operating company (hereafter abbreviated as "third site operating company") 8 is a separate business entity from the first site operating company 2 and the second site operating company 6, and is the second manufacturer of the lottery product resale system 100 (see FIG. 2), and operates the lottery sales site 81E under a contract with the first site operating company 2.

The fourth lottery sales site operating company (hereafter abbreviated as "fourth site operating company") 9 is a separate business entity from the first site operating company 2, the second site operating company 6, and the third site operating company 8, and is a licensed company that has entered into a license agreement with the first site operating company 2, and operates the lottery sales site 91F under the license agreement with the first site operating company 2.

Lottery sales site 21A, lottery sales site 21B, lottery sales site 21C, lottery sales site 61D, lottery sales site 81E, and lottery sales site 91F are connected via communication to one resale site 22, which is a market.

In the lottery product resale system 100 (see Figure 2), there are multiple lottery sales sites operated by different businesses, but there is only one resale site, resale site 22, operated by first site operating company 2, which is the management company of this lottery product resale system 100.

Figure 4 is an explanatory diagram showing the flow of a commercial transaction using the lottery product resale system 100 (see Figure 2).

If a lottery purchase user purchases lottery products at lottery sales site 21A, lottery sales site 21B, lottery sales site 21C, lottery sales site 61D, lottery sales site 81E, and lottery sales site 91F and finds that they do not need any of the lottery products, they put the unwanted items up for sale at resale site 22 of department (market) 2-2 of the first lottery sales site operating company.

When a resale purchaser purchases a listed item and requests that it be shipped to said resale purchaser, the first site operating company 2 will ship the item to said resale purchaser (within 3 to 14 days) from the first product management section 3-1 (direct sales store, warehouse, etc.) or the second product management section 3-2 of the product management section 3, and will transfer the amount, deducting a 7% commission fee, from the purchase price of the item by the resale purchaser to the account of the seller of the item.

In this case, the process of shipping the item and transferring the purchase price of the item minus a 7% commission fee to the account of the seller is the same for users who purchase items by lottery when they sell resale items.

When lottery purchase users and resale product purchase users list items, they list them in "yen currency."
In order for lottery purchase users and resale product purchase users to purchase put-upon products, they must register as members of the lottery product resale system 100 (see S22 and S23 in FIG. 8).

For example, if Taro acquires a product from our system developed by second site operating company 6 through a lottery sale on lottery sales site 61D and selects "list" for the acquired product on resale site 22, the product will be listed on the market with Taro as the seller. If Masayoshi purchases the listed product, second site operating company 6 will ship the product to product management department 3 of first site operating company 2. As soon as the product arrives at first site operating company 2, first site operating company 2 will ship it to Masayoshi. First site operating company 2 will transfer the amount of the sales minus a commission fee (7% in this embodiment) to Taro.

Therefore, in this embodiment, when an item offered for sale on the resale site 22 is purchased, the first site operating company 2 will ship the item.

Figure 5 shows the hardware configuration of the lottery resale server.

The lottery resale server 10 includes a processor 101, a RAM 102, a ROM 103, a storage 104, a display 105, and a communication I/F 106, which are connected to each other via a bus 107.

A wired or wireless network communication device 108 is connected to the communication I/F 106 for connecting to the network 40. It is connected to each of the lottery operation terminal 20 and the resale purchase terminal 30 via the network communication device 108.

FIG. 6 is a functional block diagram of the lottery resale server 10.

The lottery resale server 10 includes a user registration unit 110, a login processing unit 120, a lottery sales control unit 130, a resale control unit 140, a payment processing unit 150, a user information storage unit 160, and a product information storage unit 170. Each of these units is realized by the processor 101 loading into the RAM 102 and executing a program installed in the ROM 103 or storage 104 of the lottery resale server 10.

The user registration unit 110 stores and updates user information in the user information storage unit 160.

The login processing unit 120 executes login processing in response to login requests from the lottery operation terminal 20 and the resale purchase terminal 30.

The lottery sales control unit 130 controls lottery sales sites where products can be purchased through a lottery process. For example, it controls packaging sales sites and sales sites that involve so-called gacha operations. Prizes in gacha operations are an example of products that are assigned based on the results of a lottery operation.

The resale control unit 140 controls the resale site to resell the products sold via the lottery sale control unit 130 in response to a request from the lottery operation terminal 20.

The payment processing unit 150 performs payment processing for purchases made by the lottery sales control unit 130 and the resale control unit 140.

The product information storage unit 170 stores product information for sale by the lottery sales control unit 130 and the resale control unit 140, including, for example, product names and images, sales prices, and resale information indicating that the products will be put up for sale on a resale site. It also stores collection information for each user that links the identification information of products in each user's collection with the user information.

FIG. 7 is a hardware configuration diagram of the lottery operation terminal 20 and the resale purchase terminal 30.

The lottery operation terminal 20 and the resale purchase terminal 30 are both terminals operated by general users who access the lottery resale server 10, and may be, for example, a smartphone, tablet, laptop, or personal computer, and the model is not limited.

The lottery operation terminal 20 and the resale purchase terminal 30 each include a processor 181, a RAM 182, a ROM 183, a storage 184, a display 185, an operation input interface 186, and a network communication device 187, which are connected to each other via a bus 188.

The operation input interface 186 may be, for example, a touch sensor or a keyboard.

Figure 8 is a flowchart showing the processing flow of the lottery product resale system 100 (see Figure 2).

The product owner 1 puts up for sale his/her product in the product management section 3 on the lottery sales site 21 (S21).

The lottery resale server 10 operated by the first lottery sales site operating company determines whether the lottery purchase user 4 is a registered member (S22).

If the lottery purchase user 4 is already a registered member (S22: Yes), the process proceeds directly to S24. If the lottery purchase user 4 is not already a registered member (S22: No), the lottery purchase user 4 performs a member registration process before proceeding to S24.

The lottery purchasing user 4 accesses the lottery sales site 21 to enter the lottery and make a payment (S24). This lottery action is an operation in which the lottery purchasing user 4 purchases a product from the lottery operation terminal 20 without knowing what the product is. Specific examples of lottery actions include, for example, drawing a lottery ticket (including so-called gacha) and selecting packaging. The product that the lottery purchasing user 4 wins (the winning product) is temporarily added to the lottery purchasing user 4's collection.

The lottery purchase user 4 performs an operation to receive the product (for example, an operation to request shipping to oneself, an operation to redeem points, etc.), or an operation to list the product for resale (S25).

When the lottery purchase user 4 performs the receiving operation (S25: product receiving operation), the first site operating company 2 performs the shipping procedure to the address specified by the lottery purchase user 4 (S26). Alternatively, if the product is digital data, this may be replaced by a process of sending the lottery purchase user 4 a URL for downloading. In the case of NFT data, the data of the lottery purchase user 4 is added and then transmitted to the lottery operation terminal 20. Alternatively, the product may be converted into points. Then, the process ends.

When the lottery purchase user 4 performs a listing operation (S25: listing operation), the lottery purchase user 4 performs a procedure for listing the product on the resale site 22 (S27). If the product is NFT data, the lottery purchase user 4's data is added and then the product is listed on the resale site 22.

The resale product purchasing user 5 accesses the resale site 22 (S28).

If the resale product purchasing user 5 does not want to purchase an item from the resale site 22 (S29: No), the resale product purchasing user 5 stops accessing the resale site 22 and ends the process. If the resale product purchasing user 5 wants to purchase an item from the resale site 22 (S29: Yes), the resale product purchasing user 5 performs the resale product purchase operation and pays for the item (S30).

The lottery resale server 10 adds the purchased resale item to the collection of the resale item purchasing user 5, and when the resale item purchasing user 5 requests the shipment of the resale item, or requests the transmission of the item data if the item is digital data, the lottery resale server 10 sends or transmits the item accordingly (S31). After this, a 7% commission is deducted (subtraction process) from the sales amount (the purchase price of the item by the resale item purchasing user 5) (S32), and the deducted amount is transferred to the account of the seller of the item (S33). At that time, the lottery resale server 10 may pay the amount after deducting the resale commission to the lottery purchasing user 4. Also, if the item is NFT data, the lottery resale server 10 further adds information about the resale item purchasing user 5 to the data of the lottery purchasing user 4, and then transmits it to the resale item purchasing user 5.

Figures 9 to 11 are examples of screen displays on a lottery sales site.

Screen 200 in FIG. 9 is one example of a screen displayed on a lottery sales site, and includes an image 201 of the package A being sold, a purchase quantity input field 202, a total purchase amount display field 203, and a purchase confirmation button 204. When input is made in purchase quantity input field 202 on the lottery operation terminal 20, the purchase amount is displayed in total purchase amount display field 203. After confirming this, pressing purchase confirmation button 204 on the lottery operation terminal 20 transitions to screen 210 in FIG. 10.

Screen 210 in FIG. 10 is one example of a screen displayed on a lottery sales site, and displays information 211 about each product purchased through the lottery, product handling designation buttons 212 that allow the selection of three types of handling for each product in a pull-down menu: "Request shipping," "List," or "Redeem points," and a decision button 213. If "Request shipping" is checked on the lottery operation terminal 20, the digital product will be sent to an address specified by the operator of the lottery operation terminal 20, or to a specified storage device or address, and if "List" is checked, the product will be listed on a resale site. Pressing the decision button 213 transitions to screen 220 in FIG. 11. If "Redeem points" is selected, points equivalent to the value of the winning product can be received.

Screen 220 in FIG. 11 is one example of a screen displayed on a lottery sales site, and displays information 221 about each product purchased through the lottery process, a shipping destination information field 222 that includes an input field for the shipping destination for each product and a display field for shipping fees, and a confirm button 223. When the necessary information is entered in the shipping destination information field 222 on the lottery operation terminal 20 and the confirm button 213 is pressed, the screen transitions to screen 300 in FIG. 12.

Screen 300 in FIG. 12 is one example of a screen displayed on a resale site, and is a screen for inputting sales information about products purchased via a lottery that will be resold. Screen 300 displays product information 301, a sales price input field 302, a deposit account designation field 303 for when the resale product is sold, and a confirmation button 304. By inputting the necessary information into sales price input field 302 and deposit account designation field 303 on the lottery operation terminal 20 and pressing confirmation button 304, the product purchased via a lottery can be put up for sale on the resale site.

Screen 310 in FIG. 13 is one example of a screen displayed on a resale site, and is a sales page screen for a resale item. Screen 310 displays item information 311, a sales price display field 312, and a purchase button 313. By specifying the item to be purchased on the resale purchase terminal 30 and pressing the purchase button 313, the operator of the resale purchase terminal 30 can purchase the resale item.

Screen 230 in FIG. 14 is another example of a lottery sales site, where users draw a lottery (known as gacha) as a lottery activity and purchase a product according to the lottery result. Screen 230 displays an input field 231 for the number of times to draw gacha, and a purchase button (illustrated as "Draw gacha") 232. Pressing purchase button 232 transitions to screen 240 in FIG. 15.

Screen 240 in FIG. 15 is another example screen of a lottery sales site, and shows an example of a game card being won as an example of a prize won in a lottery (so-called gacha). Screen 240 includes a card information display field 241, a product shipping request button 242, a point redemption button 243, and a "list" button 244. Pressing the "request shipping" button 242 transitions to screen 220 in FIG. 11 for requesting the shipping of the product if the user has won a game card. Pressing the point redemption button 243 transitions to a screen for requesting point redemption for the product if the user has won a game card. Pressing the "list" button 244 transitions to screen 300 in FIG. 12 for listing the product if the user has won a game card on a resale site.

<Summary of the configuration and effects of the embodiment of the present invention>
To summarize the configuration and effects of an embodiment of the present invention, the product sales server (lottery resale server 10) comprises a lottery sales control unit 130 that accepts product purchase requests via a lottery action, and a resale control unit 140 that accepts resale requests for products purchased via the lottery action.

The product purchased through the lottery is a product that has been allocated based on the results of the lottery operation.

The product sales server (lottery resale server 10) is managed by the first business operator, and the product sales server further includes a shipping control unit (lottery sales control unit 130, resale control unit 140, and circuits and programs for accepting product shipping requests from the payment processing unit 150) that accepts shipping requests for products purchased through the lottery action, and the shipping control unit accepts product shipping requests from servers (lottery server 11 operated by a second lottery sales site operating company, lottery server 12 operated by a third lottery sales site operating company, and lottery server 13 operated by a fourth lottery sales site operating company) managed by a second business operator other than the first business operator.
In a product sales system (lottery product resale system 100) according to an embodiment of the present invention, the product sales server can be communicatively connected to a lottery operation terminal 20 that purchases products from the product sales server via a lottery action, and a resale purchase terminal 30 that purchases resold products from the products purchased by the lottery operation terminal via the lottery action.

According to this embodiment, if a consumer who purchases a product through a lottery does not need the product, they can put the product up for resale on a resale site, making it easier to get an opportunity to make effective use of the unused item. This reduces the disposal rate of unused items and contributes to a sustainable society.

In addition, in the product sales system (lottery product resale system 100) according to an embodiment of the present invention, a 7% commission was deducted from the purchase price of the product by the resale product purchaser and transferred to the account of the seller of the product, but various commission rates other than 7%, such as 5% or 10%, can also be applied.
