Specifically, as shown in fig. 5 to 6, the bottom of the interlayer plate 6 is attached to the upper side of the bottom plate 5, that is, the interlayer plate 6 is only connected to the side wall 4, only one detachable bottom plate 5 is present at the bottom of the lining interlayer 3, the main bottom plate 13 is the part of the bottom plate 5 located in the main space, the sub bottom plate 14 is the part of the bottom plate 5 located in the sub space, and after the bottom plate 5 is pulled and pressed by the extraction part 9, the food, ingredients and side dishes separately placed in the main space and the sub space fall onto the soup, rice or pasta below at the same time.

EXAMPLE III

As shown in fig. 7 to 10, the present invention provides a pressure-pull lining container, which is different from the first embodiment in the structure of the lining interlayer 3, in the present embodiment, the inside of the lining interlayer 3 is provided with a interlayer plate 6 connected to the sidewall 4, the interlayer plate 6 separates the first accommodating space into a main space and at least one subspace, the main space bottom is a main bottom plate 13, and the subspace bottom is a subspace 14. And because the sub-floors 14 are at different levels, to hold different amounts of food or solid ingredients.

Specifically, the main bottom plate 13 is a bottom plate provided with an extraction part 9, the main bottom plate 13 is in point connection with the bottom of the interlayer plate 6 through a plurality of connection points 7, and a plurality of gaps 8 surrounding the main bottom plate 13 are formed between the connection points 7. After the main bottom plate 13 is pressed and pulled by the extraction part 9, the food or the side dish in the main space directly falls on the soup, the rice or the wheaten food below.

Meanwhile, the division plate 6 can be in various structural shapes, and can be in a straight line shape, a Y-shaped structure, a cross shape, an arc shape, a star shape and other structures, and the arrangement shape of the division plate 6 and the number of the partitioned subspaces can be changed by a person skilled in the art according to actual needs.

Further, as shown in fig. 7 to 8, in the present embodiment, at least one sub-bottom plate 14 is in point connection with the bottom of the side wall 4 and the bottom of the interlayer plate 6 through a plurality of connection points 7, a plurality of gaps 8 surrounding the main bottom plate 13 are formed between the connection points 7, and the sub-bottom plate 14 is provided with an extraction portion 9. Since there is no direct connection between the main bottom plate 13 and each sub bottom plate 14, the extraction part 9 on the sub bottom plate 14 is pressed and pulled separately, so that the side dishes or seasonings separated from the main space in the sub space can be mixed with the food below.

Further, as shown in fig. 9 to 10, in the present embodiment, at least one sub-floor 14 is fixedly connected to the bottom of the side wall 4 and the bottom of the interlayer plate 6, i.e., the bottom of the sub-space is in a completely sealed structure. Because the subspaces are not communicated with each other and the main soleplate 13 and the subspaces 14 are not directly connected, the food or the seasoning can be placed in the individually sealed subspaces, after the main soleplate 13 is pressed and pulled by the extracting part 9, the food or the seasoning in the main space directly falls into the soup, the rice or the wheaten food below, and the food or the seasoning in the subspaces still exists, so that a user can selectively take and place proper dosage in the food to adapt to different requirements of different users. For example, the food in the main space is pasta, the food in the second accommodating space is soup, and the food in the sub-space is a small amount of pepper, seasoning or pickles. Or the food in the main space is a main dish, the food in the second accommodating space is rice, and the food in the sub-space is a small amount of sauce or pickles.

For example, a milk tea beverage including a liquid solvent, such as drinking water, contained in the second containing space of the cartridge body 1 and a solid component placed in the first containing space is produced and sold using the pressure-pull extraction-type inner liner container provided by the present invention. The milk tea beverage comprises the following solid components: granular additives such as Margarita, rhizoma Amorphophalli, coconut, and semen Phaseoli, and powdery additives such as coloring powder, milk powder, and cocoa powder. Therefore, according to the types of the solid components, the cross-shaped interlayer plate 6 is arranged in the inner lining interlayer 3 to divide the first containing space of the upper layer into 4 main spaces and sub-spaces with uniform or different sizes, and the depths of the sub-spaces are different according to the content of each component, namely, the sub-bottom plates 14 of the sub-spaces are positioned at different levels, for example, the volume and the weight of pearls are heavier than those of konjac, additives and additives, so that the main space for placing the pearls is the largest, and the main bottom plate 13 is positioned at the lowest level. The main bottom plate 13 and the sub bottom plate 14 are both provided with the extraction parts 9, the solids in the main space and the sub spaces are poured into the second containing space at the lower layer through the extraction parts 9, and the solid components are mixed with the solvent at the lower part, so that the delicious milk tea beverage with colorful colors can be prepared. Since solid components such as Margarita and rhizoma Amorphophalli contained in the milk tea beverage are separated from solvent for a long time, the product has good elasticity, and can prevent deterioration of solid components due to long-time mixing with liquid. Wherein, can place the ice-cube in the subspace of one of inside lining interlayer 3, avoid the ice-cube to contact with other batching and reduce the taste of batching, also avoid the ice-cube to contact with the liquid solvent in the second accommodation space and melt.

For another example, the utility model provides a press and draw formula inside lining container of drawing produces and sells a mixed sand ice, places sand ice in the second accommodation space, divides to open in main space and subspace and puts various fruit, coconut palm fruit, solid batching such as chocolate in first accommodation space to empty the second accommodation space of lower floor through the solid in main space and the subspace of extraction portion 9, solid batching mixes with the sand ice of below, can allot delicious and colorful mixed sand ice of colour. Not only ensures that the ingredients such as fruits and the like still have proper mouthfeel, but also avoids the problem that the solid ingredients are mixed with the ice-cream for a long time to accelerate the melting of the ice-cream.
