[0028] Hereafter, the present invention will be described in detail with reference to embodiments of the present invention illustrated in the accompanying drawings. References such as "one embodiment," "an embodiment," and "an exemplary embodiment" indicate that the described embodiments may include certain features, structures, or characteristics, but not all embodiments necessarily include such features, structures, or characteristics. Furthermore, such phrases do not necessarily refer to the same embodiments. Furthermore, where certain features, structures, or characteristics are described in relation to an embodiment, whether explicitly stated or not, any effect of such features, structures, or characteristics in relation to other embodiments shall be known to those skilled in the art.

[0029] The embodiment includes a cooler 100 for storing and distributing a plurality of products 10. The products 10 can be stored in product compartments 114 that can be accessed by consumers through an upper door 130 and a vertical door 140. The cooler 100 includes a folding shelf 120 and at least one lower shelf 126 disposed below the folding shelf 120. In the embodiment, the cooler 100 is configured to facilitate increased airflow within the product compartments 114. In the embodiment, the upper door 130 and the vertical door 140 are configured to enhance the visibility of the products 10 disposed within the product compartments 114.

[0030] The products 10 stored in product compartment 114 may include any desired perishable or non-perishable products. In one embodiment, product 10 includes individually packaged products such as bottles, cans, or bags. Product 10 may include, but is not limited to, soft drinks, water, carbonated water, dairy drinks, juices, alcoholic beverages, sports drinks, smoothies, coffee drinks, tea drinks, and milkshakes. Product 10 may also include snack foods.

[0031] For example, as shown in Figures 1 and 2, the cooler 100 includes a housing 110 that forms an outer casing for the cooler. The interior of the housing 110, including an inner wall 115, defines a product compartment 114. In this embodiment, the product compartment 114 is a single, integrated product compartment. In this way, the product compartment 114 does not include a separating wall, and access to the product compartment 114 provides access to all products 10 stored in the cooler 100. The housing 110 can be made of plastic or other suitable material that can provide insulation for the product compartment 114. In this embodiment, the cooler 100 includes a frame 112 for providing support for the cooler 100, and the housing 110 is disposed around the frame 112. The cooler 100 may include wheels 117 so that it can be easily moved by a user. The cooler can have any desired size and shape.

[0032] The upper door 130 is coupled to the upper surface 116 of the housing 110 by a hinge assembly 150 and is configured to cover the upper opening 30 within the cooler 100. For example, a handle 136 disposed on the upper door 130 at its leading edge 131 can be operated by the user to move the upper door 130 to the open position and gain access to the product compartment 114. In some embodiments, the hinge assembly 150 can be coupled to a motor and controller so that the upper door 130 can be automatically opened and / or closed without manual operation.

[0033] In one embodiment, the hinge assembly 150 comprises a gas spring hinge including a hinge 152 coupled to the housing 110 and the upper door 130, and a pneumatic cylinder 154 coupled to the housing 110 and the upper door 130. Thus, the pneumatic cylinder 154 of the hinge assembly 150 is configured to facilitate the easy opening of the upper door 130 and to facilitate the controlled, slow closing of the upper door 130. In one embodiment, the hinge assembly 150 is coupled to the upper door 130 at the rear panel 134. In one embodiment, the hinge assembly 150 is fully installed within the product compartment 114 when the upper door 130 is in the closed configuration, as shown, for example, in Figure 8.

[0034] In some embodiments, the upper door 130 is curved, for example, as shown in Figures 1 to 4. In some embodiments, the upper door 130 includes a panel 132, which is a curved transparent panel 132, for example, as shown in Figure 1. In some embodiments, the transparent panel 132 is a multi-pane glass panel. In this way, the transparent panel 132 can provide reduced heat loss from the cooler 100. In some embodiments, the upper door 130 extends from the foremost edge 111 of the housing 110 to the rearmost edge 113 of the housing 110, for example, as shown in Figure 3. In some embodiments, all or part of the panel 132 can be opaque. Compared to a chest cooler, for example, a cooler 100 having a curved upper door 130 can allow the use of smaller product compartments 114 without reducing product storage capacity.

[0035] In one embodiment, the upper door 130 includes a rear panel 134 positioned at the rear of the upper door 130. The rear panel 134 can be positioned horizontally, substantially parallel to the ground, as shown in Figure 2, for example. In one embodiment, a transparent panel 132 extends from the foremost edge 111 of the housing 110 to the rear panel 134, and the rear panel 134 extends from the transparent panel 132 to the rearmost edge 113 of the housing 110. In one embodiment, the rear panel 134 and the transparent panel 132 together constitute the entire upper door 130 and the upper opening 30 of the cover. In one embodiment, the rear panel 134 can move together with panel 132, as shown in Figure 3, for example, so that the rear panel 134 and panel 132 open when the upper door 130 is opened. In one embodiment, the rear panel 134 can be fixed so that it does not open or move when the upper door 130 is opened, and the fixed upper surface of the rear panel 134 can be used to hold surrounding products such as bottles and snack packets. For example, as shown in Figure 3, in one embodiment, the hinge assembly 150 can operate so that the upper door 130 can be opened to an angle Θ of about 60 to about 90 degrees between the rear panel 134 and the upper surface 116 of the housing 110, based on the height of the cooler. This can facilitate access to products in the product compartment 114. In some embodiments, the upper door 130 may include a lock to prevent access to the product compartment 114 through the door. The rear panel 134 can be transparent or opaque.

[0036] The vertical door 140 is coupled to the housing 110 and is configured to cover a vertical opening 40 formed in the front 118 of the cooler 100. In embodiments, the vertical door 140 includes a transparent panel 142. In embodiments, the vertical door 140 is substantially perpendicular to the floor, and all shelves within the product compartment 114 are substantially parallel to the floor, for example, as shown in Figure 2. In this way, the planes of the horizontal opening 30 and the vertical opening 40 are also substantially perpendicular. In some embodiments, the vertical door 140 may include a lock to prevent access to the product compartment 114 through the door. In embodiments, the vertical door 140 is a full-length door that covers the entire front 118 of the cooler 100.

[0037] The cooler 100 includes a plurality of shelves for storing and displaying products 10 within a product compartment 114. In an embodiment, the cooler 100 includes a folding shelf 120 having an upper shelf 122 and a lower shelf 124. In one embodiment, the folding shelf 120 is the top shelf in the cooler 100. One or more lower shelves 126 are arranged below the folding shelf 120. Products 15 may be arranged in a first row of a given shelf, and products 17 may be arranged in a second or rear row. The folding shelf 120 is configured to move between an extended position in which the lower shelf 124 extends away from the upper shelf 122 and a retracted position in which the lower shelf 124 retracts and is positioned directly below the upper shelf 122. In an embodiment, for example, as shown in Figures 5 and 6, the cooler 100 may include rollers 121 coupled to the inner wall 115. At least one of the lower stage 124 and the upper stage 122 may be mounted on a roller 121 to facilitate the movement of the lower stage 124 relative to the upper stage 122. In this embodiment, the upper stage 122 can move relative to the lower stage 124. The roller 121 may be mounted along the length of the lower stage 124 and the upper stage 122.

[0038] In the embodiment, the product 12 arranged on the upper shelf 122 and the product 14 arranged on the lower shelf 124 are visible through an upper door 130 including a transparent panel 132, as shown, for example, in Figure 1. In the embodiment, the product 12 arranged on the upper shelf 122 and the product 14 arranged on the lower shelf 124 are visible through an upper door 130 including a transparent panel 132, as shown, for example, in Figure 1, and the product 16 arranged on the lower shelf 126 is visible through a vertical door 140 including a transparent panel 142. Improved visibility of the product 10 arranged in the product compartment, including the products arranged in the first row and the row behind the cooler 100, can promote consumer awareness and purchase. The interior of the housing 110 may include lighting, such as LED lighting positioned in the center of the door, so that both the product 12 and product 14 arranged on the folding shelf 120, and the product 16 arranged on the lower shelf 126, are clearly illuminated.

[0039] In this embodiment, the folding shelf 120 facilitates access to products located within the product compartment 114. Referring to Figure 4, when the lower shelf 124 is in the retracted position, the user can more conveniently access the products located within the product compartment 114. For example, when the lower shelf 124 is in the retracted position, the user can access the products 16 located on the lower shelf 126 via the upper door 130. This can provide further convenience to the operator (e.g., the user or store owner) based on consumer demand, such as when the products located within the cooler 100 include seasonal products. For example, during times of lower consumer demand (e.g., during winter), the folding shelf 120 can be set in the extended position, and products can be located on the upper shelf 122 and the lower shelf 124. At the same time, the operator (e.g., the store owner) can choose not to store products within the product compartment 114 below the folding shelf 120. The operator can choose to lock the vertical door 140 so that consumers can access only the products inside the cooler 100 through the upper door 130. In this way, when demand is low and only a small number of products are needed, the cooling capacity of the cooler 100 can be efficiently maintained, and overall energy consumption can be reduced. In addition, the storage capacity and usage capacity of the cooler 100 can be made flexible.

[0040] In this way, the user can access products 10 located in two separate areas of the product compartment through the same door. For example, the user can access products located in the upper part of the product compartment 114 (products located above the folding shelf 120) and products located in the lower part of the product compartment 114 (products located below the folding shelf 120) through the upper door 130. In this embodiment, the user can simultaneously access the products in the lower part of the product compartment 114 through a separate access, namely the vertical door 140.

[0041] A cooling unit 160 for cooling and maintaining the temperature of the product compartment 114 is housed within the housing 110. The cooling unit 160 can be, for example, a refrigeration system. The cooling unit 160 can be housed within the housing 110 partially or entirely. The cooling unit 160 includes a compressor 162, an internal condenser 164, an evaporator 166, and a fan 168, all operably connected to generate and distribute cooling air within the product compartment 114. In one embodiment, for example, as shown in Figure 2, the evaporator 166 is housed within the housing 110. In one embodiment, the compressor 162 and condenser 164 are housed below a lower shelf 126, which is the lowest shelf in the product compartment 114. For example, in one embodiment, the compressor 162 and condenser 164 are housed within a cavity 119 formed within the housing 110. The cavity 119 may be located at the rear of the product compartment 114 below the lower shelf 126, so that the product 10 can be placed in the cooler 100 in front of the cavity 119, for example, as shown in Figure 2. In other embodiments, the condenser 164 may be located externally, for example, on the outer rear of the housing 110.

[0042] Referring to Figure 10 of the embodiment, the cooler 100 is configured to facilitate an increase in airflow, schematically indicated by the arrow 200. Specifically, the upper door 130 and the folding shelf 120 can be configured to facilitate an increase in airflow within the product compartment 114, which can result in improved air distribution and uniform cooling within the cooler. As shown in Figure 10, for example, air from the cooling unit 160 can be blown into the product compartment 114 by a fan 168 so that the air moves along the rear inner wall 115 of the cooler, which includes the evaporator 166. The product compartment 114 is configured such that air is deflected from the top surface of the cavity 119 and the floor of the product compartment 114, and then moves within the compartment. In particular, in embodiments where the panel 132 is curved, when the airflow reaches the panel 132 of the upper door 130, the air is deflected so that it simultaneously reaches the product 14 on the lower shelf 124 and the product 12 arranged on the upper shelf 122, as well as the product 15 arranged in the first row on a given shelf and the product 17 arranged in the second row or rear row.

[0043] Further embodiments of the upper door 130 are described with reference to Figures 11 to 18. Embodiments of the upper door 130 can be used in conjunction with any one or more of the features described herein. In embodiments, the upper door 130 comprises a single full-length panel 132 extending from the front edge 111 to the rear edge 113 of the housing 110, as shown, for example, in Figure 11. In embodiments, the upper door 130 comprises a single flat panel 132 angled upward from the front edge 111 to the rear edge 113 of the housing 110, as shown, for example, in Figure 12. In embodiments, the upper door 130 comprises two curved doors that can be opened by sliding the doors to the left or right toward the center of the upper door 130, respectively, as shown, for example, in Figure 13. In embodiments, the upper door 130 comprises two flat doors that can be opened by sliding the doors to the up or down toward the center of the upper door 130, respectively, as shown, for example, in Figure 14. In an embodiment, the upper door 130 comprises two flat doors that can be opened by sliding the doors to the left or right toward the center of the upper door 130, for example, as shown in Figure 15. In an embodiment, the upper door 130 comprises two flat hinged doors that can be opened, for example, as shown in Figure 16. In an embodiment, the upper door 130 comprises a fixed rear panel 134 and a hinged front door, for example, as shown in Figure 17. In an embodiment, the upper door 130 comprises a full-length transparent panel 132 and transparent side panels 138, for example, as shown in Figure 18. In an embodiment, the upper door 130 is a transparent, fully bowl-shaped cover with curved panels on each side of the cooler 100, for example, as shown in Figure 19. This can facilitate product visibility from all sides of the cooler 100. In an embodiment, the upper door 130, or a part thereof, may be provided with transparent panels so that products inside the cooler 100 may be visible.

[0044] In an embodiment, the cooler 100 may include an external storage device 170 for storing and displaying products 10 outside the cooler housing 110. In an embodiment, for example, as shown in Figures 20 and 21, the external storage device 170 may comprise one or more baskets 170 that can be mounted on the cooler housing 110 by a mounting member 172. The mounting member 172 may include a bracket fixed to the housing 110 and an opening for receiving a portion of the basket 170. The external storage device 170 may be modular and can be efficiently added to and removed from the housing 110.
