An infusion bag for preparing an infusion

Abstract

This utility model discloses an extraction bag for preparing extracts, relating to the field of detection tool technology. It includes a bag body with a top opening and a bag opening at the top of the top of the top opening. Self-sealing strips are fixed to the top of the inner walls on both sides of the bag opening. By designing the bag body with a folded portion at the bottom and an elliptical structure at the bottom, this utility model allows the sample to be injected into the bag body through the bag opening during extraction. The sample can expand the bag body, causing the folded portion at the bottom to unfold, forming a larger support surface for easy placement of the bag. Simultaneously, the self-sealing strip inside the bag opening seals the bag after the sample is injected. Compared to existing technologies, this technical solution uses a bag design that can be flattened or unfolded, facilitating the carrying and use of the extraction bag and effectively reducing extraction costs.

Description

Technical Field

[0001] This utility model relates to the field of detection tool technology, and in particular to an extraction bag for preparing extracts. Background Technology

[0002] Leaching is a process that selectively dissolves target components from solid materials using a solvent. It has two applications: in the field of traditional Chinese medicine, it refers to transferring soluble substances from medicinal materials to a solvent; in the field of metallurgy, it refers to dissolving specific mineral components in mineral concentrates.

[0003] In the prior art, such as the extraction bottle with publication number CN219635900U, which relates to the field of extraction bottles, the extraction bottle includes a bottle body and a cap assembly located at the port of the bottle body. The cap assembly includes an inner cap and an outer cap. The bottom of the inner cap has several through holes, and the cap opening extends outward to form a cap edge. A breathable and waterproof membrane is laid on each of the through holes. The inner cap is placed at the port of the bottle body through the cap edge. The outer cap also has vent holes to release gas inside the bottle. The outer cap is rotatably connected to the port of the bottle body to fix the inner cap at the port of the bottle body. This utility model, by providing through holes in the inner cap and providing a waterproof and breathable membrane on the through holes, allows the extraction bottle to be degassed during inversion and vibration, replacing the manual degaussing method and avoiding the phenomenon that excessive air pressure inside the bottle can loosen the inner cap and cause leakage of the extraction liquid.

[0004] In the existing technology, when extracting samples, the samples need to be weighed and placed in an extraction bottle, and then the corresponding solution is added for extraction. When there are many samples, a large number of glass Erlenmeyer flasks are required, which is costly and inconvenient to carry.

[0005] Therefore, it is necessary to invent an extraction bag for preparing extracts to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an extraction bag for preparing extracts, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an extraction bag for preparing an extract, comprising a bag body, a top end of the bag body having a closure, a top end of the closure having a bag opening, self-sealing strips fixedly provided on the top ends of the inner walls on both sides of the bag opening, a folded portion at the bottom end of the bag body, the cross-section of the folded portion being an "M" shape, sealing edges fixedly provided on both sides of the bag body, support sheets provided on both sides of the sealing edges, one end of the support sheet being connected to the edge of the outer wall of the bag body, multiple rigid films provided on the outer wall of the support sheet, the multiple rigid films being arranged sequentially from bottom to top, and one end of the rigid films being connected to the outer wall of the bag body, multiple reinforcing ribs fixedly provided on both sides of the bag opening, the multiple reinforcing ribs being arranged sequentially from bottom to top, a positioning rib adhered to the top end of the outer wall of the bag opening, a bent portion fixedly provided at both ends of the positioning rib, a deformable rib fixedly provided in the middle of the outer wall of the positioning rib, and the two ends of the deformable rib extending to the outside of the two bent portions respectively.

[0008] Preferably, the top of the sealing edge is provided with a bevel, and the bevel is flush with the outer side wall of the sealing edge.

[0009] Preferably, the bottom of the bag is designed as an elliptical structure.

[0010] Preferably, the dermal membrane is configured as a triangular structure.

[0011] Preferably, the cross-section of the reinforcing rib is a semi-circular structure, and the two ends of the reinforcing rib are flush with the two sides of the bag opening.

[0012] Preferably, the reinforcing ribs on both sides of the bag opening are arranged in an alternating pattern.

[0013] Preferably, the positioning rib is designed as a flat structure.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model features a bag body with a folded section at the bottom and an elliptical structure at the bottom. During sample extraction, the sample can be injected into the bag through the opening at the top. The sample can open the bag, allowing the folded section at the bottom to unfold, forming a larger support surface for easy placement of the bag. Additionally, a self-sealing strip is provided inside the bag opening, sealing the bag after the sample is injected. Compared to existing technologies, this design uses a bag that can be flattened or unfolded, facilitating the carrying and use of the extraction bag and effectively reducing extraction costs.

[0016] 2. This utility model, by setting a support page and a rigid film, allows the support page to move along the edge of the bag as it is opened by the sample. This causes the support page to unfold relative to the sealing edge, and the unfolded support page can improve the placement surface at the bottom of the bag, thereby enhancing the placement stability of the bag. By setting reinforcing ribs and positioning ribs on the outside of the bag opening, the bag opening can be folded along the reinforcing ribs after the sample is injected into the bag, and then pressed by the bent parts at both ends of the positioning ribs, thereby improving the sealing performance of the bag and ensuring the stability and sealing of the sample placement during the extraction process.

[0022] 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.

[0023] This utility model provides, for example Figure 1-4 An extraction bag for preparing an extract is shown, comprising a bag body 1, the bottom end of which is an elliptical structure. After the elliptical structure of the bag body 1 is expanded by the sample, its bottom end can form a support surface to facilitate the placement of the extraction bag.

[0024] The top of the bag body 1 is provided with a closure 2, and the top of the closure 2 is provided with a bag opening 3. The top of the inner walls on both sides of the bag opening 3 are fixed with self-sealing strips 4. The bottom of the bag body 1 is provided with a folding part 5. The cross-section of the folding part 5 is designed as an "M" shape. The "M" shape design allows the folding part 5 to unfold outward when the bag body 1 is opened by the sample.

[0025] Both sides of the bag body 1 are fixedly provided with sealing edges 6, and both sides of the sealing edges 6 are provided with support sheets 7. One end of the support sheet 7 is connected to the edge of the outer wall of the bag body 1. The outer wall of the support sheet 7 is provided with multiple hard films 8, which are arranged sequentially from bottom to top, and one end of the hard film 8 is connected to the outer wall of the bag body 1. The hard film 8 is designed with a triangular structure. The hard film 8 can realize the connection between the support sheet 7 and the edge of the outer wall of the bag body 1. In addition, the hard film 8 can improve the structural strength at the edge of the bag body 1.

[0026] Multiple reinforcing ribs 9 are fixed on both sides of the bag opening 3. The multiple reinforcing ribs 9 are arranged sequentially from bottom to top. The cross section of the reinforcing rib 9 is set as a semi-circular structure, and the two ends of the reinforcing rib 9 are flush with the two side edges of the bag opening 3. The reinforcing ribs 9 on both sides of the bag opening 3 are arranged in an alternating manner. When the alternating reinforcing ribs 9 are folded with the bag opening 3, they overlap each other, so that the bag opening 3 forms a hard egg roll-shaped structure.

[0027] A positioning rib 10 is glued to the top of the outer wall of the bag opening 3. The positioning rib 10 is a flat structure. Both ends of the positioning rib 10 are fixed with bent portions 11. A deformable rib 12 is fixed in the middle of the outer wall of the positioning rib 10. Both ends of the deformable rib 12 extend to the outside of the two bent portions 11 respectively. The deformable rib 12 can lock the position of the bent portion 11 after bending by its own elastic potential energy.

[0028] The top of the sealing edge 6 is provided with a bevel 13, and the bevel 13 is flush with the outer wall of the closing edge 2. The bevel 13 allows for a smooth transition between the sealing edge 6 and the closing edge 2, which facilitates the folding and storage of the distillation bag.

[0029] Working principle of this utility model:

[0030] In use, the bag body 1, the sealing opening 2, and the bag opening 3 form an extraction bag structure. When no sample is injected, the bag body 1, sealing opening 2, and bag opening 3 are in a flattened state, and the folded portion 5 is also folded and flattened for easy storage and carrying. When injecting the sample, the bag opening 3 is opened, and the measured sample is injected into the bag body 1 through the bag opening 3. After the sample enters the bag body 1, it expands the bag body 1, causing the bottom of the bag body 1 to change from an elliptical shape to an approximately circular structure, and causing the folded portion 5 at the bottom of the bag body 1 to unfold. During this process, the two side edges of the bag body 1 move relative to the sealing edge 6. The two side edges of the bag body 1, through the rigid membrane 8, drive the support sheet 7 to move, thus supporting... Page 7 moves relative to the sealing edge 6, thereby unfolding the supporting page 7. After unfolding, the supporting page 7 can form a supporting structure together with the bottom of the bag body 1 to facilitate the placement of the bag body 1. After the sample is injected, the bag opening 3 is closed and sealed by the self-sealing strip 4. Then, the bag opening 3 is rolled up towards the bag body 1. During the rolling up process, multiple reinforcing ribs 9 move with the bag opening 3 and approach each other, so that the bag opening 3 forms a high-hardness egg roll-shaped structure. After the bag opening 3 is rolled up, the deforming rib 12 is bent and fits against the outermost side of the bag opening 3. At this time, the deforming rib 12 can limit the bag opening 3. At this time, the extraction bag is sealed.

[0031] It should be noted that in this embodiment, the bag body 1, the closing 2, the bag opening 3, the folding part 5, the sealing edge 6, the support page 7, the hard film 8, and the reinforcing rib 9 are produced by injection molding. In this embodiment, the positioning rib 10, the bending part 11, and the deformation rib 12 are produced separately and combined with the bag opening 3 by bonding. The above technical means are all conventional in the art and will not be described in detail here.

[0032] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may change.

[0033] Secondly: The accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0034] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
