[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0027] Please see Figure 1-5 This utility model provides a blueberry blister box with adjustable volume and an openable bottom area, including a box body 1 and an adjustable cover 5. One end of the box body 1 is provided with a cover 2. The bottom of the inner wall of the box body 1 is provided with a protrusion 12. The top of the protrusion 12 is provided with an opening 3. The adjustable cover 5 is engaged with the surface of the protrusion 12, which can change the internal volume of the box. The bottom of the opening 3 is provided with a bottom cover 4. The inner wall of the box body 1 is provided with several lower drain outlets 6, and the inner wall of the cover 2 is provided with several upper drain outlets 7 for water to enter and exit. Blueberries can be washed without opening the cover 2. A fork 15 is placed inside the adjustable cover 5 for picking up and eating blueberries. A baking soda packet 16 is placed inside the adjustable cover 5 for easy washing of blueberries.
[0028] When in use, the inside of the adjusting cover 5 is a storage area containing a blueberry cleaning baking soda packet 16 and a cooking fork 15. The bottom of the blister pack has an openable bottom cover 4, allowing users to easily remove the built-in cleaning solution and utensils. When users need to clean blueberries, they can easily open the bottom storage area, pour the baking soda into water, and wash them. This design not only makes it convenient for users to clean blueberries but also effectively removes residual pesticides and impurities from the surface of the blueberries. The cooking fork 15 allows users to eat the blueberries directly when they take them out, avoiding the need to prepare additional utensils.
[0029] The top of the adjusting cover 5 is raised and the bottom is thick.
[0030] When in use, the shape of the adjustable cover 5 makes it take up a lot of space, and the blister box can hold 250g of blueberries.
[0031] The box body 1 has several slots 9 at the end away from the lid 2, and the lid 2 has several blocks 8 at the end away from the box body 1. Both corners of the box body 1 and the lid 2 have several anti-slip protrusions 10 to improve the anti-slip effect. One end of the bottom cover 4 has a protrusion 11 for easy lifting. Both ends of the bottom of the protrusion 12 have grooves 13. Both ends of the bottom of the inner wall of the adjusting cover 5 have protrusions 14, and the protrusions 14 engage with the inner wall of the grooves 13 to make the connection more secure.
[0032] When in use, after the lid 2 is closed, the locking block 8 inside will be locked into the slot 9 of the box body 1, so that the lid 2 will not easily lift off. The anti-slip protrusions 10 make it less likely to slip when the blister box is handled and moved. The protrusions 11 make it easy to lift the bottom cover 4 to take out the contents. The protrusions 14 and grooves 13 make the adjusting cover 5 more securely locked on the protrusion 12.
[0033] In practical use, this utility model provides a blueberry blister box with an adjustable volume and an openable bottom area. The box features a replaceable adjustable cover 5 in the middle. Different models of the adjustable cover 5 result in different internal volumes, allowing users to adjust the box volume according to the quantity and size of blueberries, thereby reducing gaps and ensuring the blueberries are securely placed inside, preventing damage. The bottom of the box has an openable bottom cover 4, allowing users to easily remove the built-in cleaning solution and cooking utensils. The area inside the adjustable cover 5 is a storage area containing a blueberry cleaning baking soda packet 16. When users need to clean blueberries, they can easily open the bottom storage area, pour the baking soda into water, and wash them. This design not only makes cleaning blueberries convenient but also effectively removes residual pesticides and impurities from the blueberry surface. A small fork can also be placed in the storage area. 15. This blueberry blister pack allows users to directly eat blueberries without needing extra utensils. The outer shell is made of transparent, food-grade plastic, protecting the blueberries while allowing users to easily see the contents. The adjustable lid 5 in the middle of the box is available in various sizes, allowing for easy adjustment of the internal volume from 200ml to 400ml, accommodating different quantities of blueberries. The bottom opening design uses a dotted line cut by a knife to allow users to remove the baking soda packet 16, mix it with water, and wash the blueberries. A fork 15 is also conveniently located at the bottom. This blueberry blister pack is suitable for packaging and storing various small fruits, especially those requiring easy washing and consumption. It provides users with a healthier, safer, and more convenient fruit-eating experience. Example
