AI Technical Summary

Technical Problem

Conventional delivery boxes with a single flap member limit the height of items that can be stored due to significant downward rotation of the flap when the lid is closed, restricting the storage capacity.

Method used

A delivery box design featuring two vertically arranged flap members that rotate under the weight of an item to drop it into a lower storage section, preventing retrieval from the inlet side.

Benefits of technology

Enhances storage capacity by approximately 150 mm, allowing larger items to be stored efficiently by minimizing flap movement during closure.

Abstract

The present invention provides a delivery box equipped with a structure that allows packages to fall from the input slot into the storage compartment, preventing them from being retrieved from the input slot side. [Solution] At least two flap members are positioned vertically below the input opening. The two flap members are configured to rotate sequentially under the weight of the package when it is inserted, causing it to fall into the storage compartment, and to prevent the package from being removed from the input opening side after storage. In addition, compared to conventional delivery boxes with a single flap member, it is possible to store packages that are approximately 150 mm taller, improving storage efficiency. Conventional delivery boxes often have a structure with a single flap member below the input opening, and when the lid is closed, this flap member rotates significantly downwards, which limits the effective height of the storage compartment and makes it difficult to store large packages.

Description

Technical Field

[0001] The present invention relates to a delivery box for receiving and storing delivered items, and particularly to a delivery box having a structure for dropping an item from an inlet into a storage section and preventing the item from being taken out from the inlet side.

Background Art

[0002] Conventionally, in a delivery box, a structure is known in which a single flap member is provided below an inlet and an item is dropped into a storage section.

[0003] However, in such a single flap member, when the lid is closed, the flap member rotates significantly downward, narrowing the upper space of the storage section, so there is a problem that the height of the item that can be stored is limited.

Patent Documents

[0004] Not described. Problems to be Solved by the Invention

[0005] The present invention has been made in view of the above problems of the prior art, and an object thereof is to provide a delivery box that ensures the effective height of a storage section and can store an item larger than before. Means for Solving the Problems

[0006] The delivery box of the present invention has an inlet for inserting an item at the upper part, and at least two flap members are arranged vertically below the inlet.

[0007] The two flap members are configured to sequentially rotate by the weight of the item when the item is inserted and drop the item into the lower storage section, and are configured to prevent the item from being taken out from the inlet side after storage. Effects of the Invention

[0008] According to this invention, by making the flap member a two-part structure, the amount of downward movement of the flap member when the lid is closed can be suppressed.

[0009] As a result, compared to conventional delivery boxes with a single flap component, it becomes possible to store packages that are approximately 150 mm taller, improving storage efficiency. [Brief explanation of the drawing]

[0010] [Figure 1] Figure 1 is an overall perspective view of the delivery box according to the present invention. [Figure 2] Figure 2 is a front view of the delivery box according to the present invention. [Figure 3] Figure 3 is a right side view of the delivery box according to the present invention. [Figure 4] Figure 4 is a left side view of the delivery box according to the present invention. [Figure 5] Figure 5 is a plan view of the delivery box according to the present invention. [Figure 6] Figure 6 is a cross-sectional view of the input opening of the delivery box according to the present invention. [Figure 7] Figure 7 shows the state when luggage is loaded. [Figure 8] Figure 8 shows the completed storage state. [Modes for carrying out the invention]

[0011] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

[0012] When using the delivery box, the user opens the lid and places the package on the slot.

[0013] Next, by closing the lid, the contents are sequentially dropped into the storage compartment by the rotational movement of the two flap members.

[0014] Once the luggage is stored in the compartment, the two flap members prevent it from being removed from the opening side.

Claims

[Claim 1] A delivery box having an opening at the top for inserting packages, Below the aforementioned opening, at least two flap members are arranged vertically. The two flap members rotate sequentially under the weight of the luggage when it is loaded, causing the luggage to fall into the storage compartment below. A delivery box characterized by being configured to prevent packages from being removed from the input slot after they have been stored.
