Description

Technical Field

[0001] The present invention relates to a mixing device, and particularly to a negative pressure mixing device for liquids and powders.

Background Art

[0002] In the prior art, a packaging assembly for preparing a suspension or solution containing an active ingredient at the time of use is known, and its structure mainly includes two parts. The packaging assembly includes two sealed containers. Among them, the first container generally contains an active ingredient in the form of dry powder, and the second container contains a liquid for mixing. When actually used, the active ingredient can be dissolved or suspended in the liquid. Generally, the packaging assembly is provided with a connecting device for communicating the two containers to realize the mixing of the liquid and the active ingredient.

[0003] As a prior art, for example, Patent Document 1 discloses "a bushing for accommodating a dropper neck, and a corresponding package and kit". Before mixing the active product and the liquid, it is necessary to remove the plug body that seals the first container. Thereby, the second container can be inserted to mix the liquid and the active product. However, at the moment when the plug body is removed, there is a risk that the first container comes into contact with the external environment and is contaminated. Also, when examining previous applications, a structure characterized by directly sealing through the plug body is disclosed. However, sealing only with the plug body is likely to cause the plug body to fall off due to impact or pressure, so the sealing performance is eliminated, and there is a risk that the active product in the bottle is contaminated.

[0004] Thereby, those skilled in the art have recognized that the above structure is prone to being exposed to the external environment before mixing, and the sealing only with the plug body has poor sealing performance. They are trying to develop a packaging assembly that can not only avoid the risk of contamination, but also improve the sealing stability and perform a more reliable mixing operation.

[0009] The terms used herein are for the purpose of describing specific embodiments and are not intended to limit the invention. Unless otherwise specified, the singular forms "one" and "the" used herein may include the plural forms.

[0010] The directional terms used herein, such as up, down, left, right, front, back, and their derivatives or synonyms, are intended to describe the direction of elements in the drawings and do not limit the present invention unless explicitly stated in the context. The technical details of the present invention will be described in detail below with reference to the drawings.

[0011] Refer to FIGS. 1 to 3. The present invention is a negative pressure mixing device for liquid and powder, including a powder bottle 10, a stopper 20, an outer sealing component 30, and an alignment kit 40. As shown in FIG. 2, a dropper bottle 90 can be assembled to the negative pressure mixing device for liquid and powder, and the solution L in the dropper bottle 90 can be mixed with the powder P in the powder bottle 10.

[0012] The powder bottle 10 includes a bottle body 11, the bottle body 11 defines a mixing space 12 and a mouth portion 13, the mixing space 12 can store the powder P, and the mouth portion 13 communicates with the mixing space 12.

[0013] The stopper 20 has a stopper body 21, a passage 22, an upper portion 23, and a plurality of linings 24. The passage 22 is provided to communicate with the stopper body 21, the upper portion 23 is connected to the stopper body 21 to seal the passage 22, the lining 24 is connected to the stopper body 21 and enters the mouth portion 13, and the stopper body 21 can be quickly inserted into the mouth portion 13 to guide the sealing of the mixing space 12 of the powder bottle 10.

[0014] When the stopper body 21 is inserted into the mouth portion 13, the mixing space 12 is sealed, so that the powder P is in a dry storage environment. The upper portion 23 has an insertion region 231, the insertion region 231 is provided facing the passage 22, the insertion region 231 is a thin-walled portion 23a in the upper portion 23, and the insertion region 231 has a pre-pressure mark 230. The pre-pressure mark 230 is provided on the thin-walled portion 23a and is located on the side close to the mixing space 12. In this example, as shown in FIG. 4, the pre-pressure mark 230 is a cross-shaped groove. In other examples, the pre-pressure mark 230 may be other geometric shapes, for example, a linear shape. The dropper mouth 91 of the dropper bottle 90 penetrates through the thin-walled portion 23a and the pre-pressure mark 230, thereby introducing the solution L into the mixing space 12, and the pre-pressure mark 230 can limit the direction of rupture of the thin-walled portion 23a, avoiding unexpected rupture in the insertion region 231 and affecting the overall sealing performance. The outside of the insertion region 231 is the thick-walled portion 23b of the upper portion 23.

[0015] Furthermore, a plurality of anti-slip protrusions 241 are provided on the surface adjacent to the mouth portion 13 of the lining 24. Preferably, the anti-slip protrusions 241 are arranged in two annular rows, and the plurality of anti-slip protrusions 241 in different rows have different shapes. Due to the friction between the anti-slip protrusions 241 and the mouth portion 13, the plug 20 can be fixed more firmly, and it is possible to prevent the plug 20 from falling off from the mouth portion 13. Furthermore, chamfered portions 242 are provided on both opposite sides of the lining 24, whereby the end of the lining 24 can enter the mouth portion 13 more easily. Since the lining 24 is in close contact with the wall surface of the mouth portion 13 when entering the mouth portion 13, the plug body 21 connected to the lining 24 can be provided upright in the mouth portion 13, and in the freeze-drying process of the liquid, water can be discharged from the passage 22.

[0016] The outer sealing component 30 includes a ring portion 31 and a cap ring 32. The ring portion 31 is fixed to the outer edge 131 of the mouth portion 13 of the powder bottle 10, and the cap ring 32 is connected to the ring portion 31 and is crimped to the upper portion 23 of the plug 20 and exposes the insertion region 231. In one example, the ring portion 31 is crimped and fixed to the mouth portion 13, for example, fixed to the outer edge 131 by roll forming, whereby the cap ring 32 connected to the outer sealing component 30 is tightened and crimped to the upper portion 23, and it is possible to prevent the plug 20 from falling off due to impact or external force. The cap ring 32 includes an annular body 321, a holding portion 322, and a hollow portion 323. The hollow portion 323 is located at the center of the annular body 321 and exposes the insertion region 231.

[0017] Furthermore, refer to Figures 5, 6A, and 6B. There are multiple gaps 324 between the annular body 321 and the holding portion 322, the gaps 324 are spaced apart and arranged in an annular shape, and pass through the cap ring 32, so that the holding portion 322 is partially connected to the annular body 321 and the holding portion 322 can be detached without much force. The holding portion 322 is configured to be torn in a single direction so that the user can remove the outer sealing component 30 from the powder bottle 10 after using the negative pressure mixing device for the liquid and powder, and separating the outer sealing component 30 from the powder bottle 10 is advantageous for sorting and recycling. Furthermore, the outer sealing component 30 further includes multiple guide indentations 33, which are provided on the ring portion 31 and the cap ring 32 and each is connected to one of the gaps 324, so that when the user wants to detach the outer sealing component 30, they do not need to use much force and are advantageous in guiding the direction in which the outer sealing component 30 is detached. In this example, the guide indentation 33 may or may not penetrate the ring portion 31 and / or the cap ring 32.

[0018] The alignment kit 40 includes a connector 41 and a sleeve ring 42. The connector 41 is connected to the cap ring 32 and penetrates axially to form a through hole 410. The sleeve ring 42 is provided at the end of the connector 41 away from the cap ring 32. After the dropper bottle 90 is removably fixed to the sleeve ring 42, the dropper opening 91 passes through the through hole 410 and the hollow portion 323, and through the insertion area 231, enters the passage 22, and communicates with the mixing space 12. In this example, a female thread 421 is formed on the inside of the sleeve ring 42, and the dropper bottle 90 has a male thread 92 corresponding to the female thread 421. When assembling, the male thread 92 is screwed into the female thread 421. In one example, the connection portion 41 of the alignment kit 40 is connected to the cap ring 32 of the outer sealing component 30 by heat melting, preferably the connection portion 41 is connected to the cap ring 32 by heat melting, and further, the ring portion 31 is fixed to the outer edge 131 of the mouth portion 13 by crimping.

[0019] Furthermore, as shown in Figure 5, a positioning hole 3231 is formed in the radial direction of the hollow portion 323. The connection portion 41 of the alignment kit 40 has a positioning convex ring 411 provided corresponding to the hollow portion 323 and a positioning projection 412 formed in the radial direction of the positioning convex ring 411, exposing the insertion region 231 when the positioning convex ring 411 is connected to the hollow portion 323. The positioning projection 412 is provided to align with the positioning hole 3231, and when the connection portion 41 is connected to the cap ring 32 by heat melting, it can face the set direction and restricts the alignment kit 40 from rotating axially relative to the outer sealing component 30, so that when the user assembles the dropper bottle 90 to the alignment kit 40, the alignment kit 40 does not rotate relative to the outer sealing component 30 due to the force applied.

[0020] As shown in Figure 7, in this example, when the stopper body 21 is inserted into the opening 13, a negative pressure environment is present. Therefore, when the stopper body 21 seals the passage 22, the mixing space 12 is under negative pressure. As a result, the powder P is stored in a dry, vacuum environment, reducing the influence of external ambient temperature and significantly extending the storage period. This is also advantageous for the solution L in the dropper bottle 90 to flow into the powder bottle 10 and mix with the powder P. Because the wall thickness of the insertion region 231 is thin (thin-walled portion 23a), when the mixing space 12 is under negative pressure, atmospheric pressure causes the insertion region 231 to collapse. By observing whether the insertion region 231 has collapsed, it is possible to directly determine whether the mixing space 12 is maintaining a negative pressure state, and furthermore, to quickly determine whether the powder P is being stored properly.

[0021] Referring to Figures 8A and 8B, in one example, the present invention further includes a sealing cap 50, which is removable and configured to shield and seal the end of the sleeve ring 42 away from the connection portion 41, and to be placed over the sleeve ring when not being mixed. The sealing cap 50 may be a lid 51 or a heat-seal film 52. If the sealing cap 50 is a lid 51, it has a flange 511, which locks and secures the sleeve ring 42. If the sealing cap 50 is a heat-seal film 52, it is directly heated by a heat-sealing machine to seal the sleeve ring 42. As a result, the inside of the sleeve ring 42 is isolated from the external environment, contamination is avoided, and it can be easily opened when in use.

[0022] Figures 9A to 9E are schematic diagrams illustrating the procedure for using this invention; please refer to these figures.

[0023] First, as shown in Figure 9A, the worker obtains a dropper bottle 90 and a powder bottle 10. Powder P is filled into the mixing space 12 of the powder bottle 10. Solution L is filled into the dropper bottle 90 and sealed with a cap 93.

[0024] Next, as shown in Figure 9B, the lid of the powder bottle 10 (lid 51 is used as an example in the figure) and the cap 93 of the dropper bottle 90 are opened. Also, as shown in Figure 9C, the dropper bottle 90 is turned upside down, and the dropper opening 91 is passed through the positioning convex ring 411 of the alignment kit 40 and the hollow portion 323 of the outer sealing part 30, and inserted into the insertion area 231. After the dropper opening 91 has passed through the insertion area 231, it communicates with the mixing space 12, and the solution L in the dropper bottle 90 enters the mixing space 12 and mixes with the powder P. Furthermore, if the mixing space 12 is under negative pressure, the speed at which the solution L enters the mixing space 12 can be further accelerated.

[0025] As shown in Figure 9D, powder P is dissolved in solution L to form mixed solution L1. After powder P is dissolved, when the dropper bottle 90 and powder bottle 10 are turned upside down, the mixed solution L1 flows back into the dropper bottle 90.

[0026] Finally, as shown in Figure 9E, the dropper bottle 90 is resealed with the cap 93, completing the mixing of the liquid and powder and making it ready for use.

[0027] As can be seen from the above explanation, this invention has the following advantages. 1. This invention effectively improves airtightness by securely fixing the stopper to the powder bottle using negative pressure sealing, thereby preventing the powder from being exposed to or contaminated by the external environment during storage.

[0028] 2. By providing an alignment kit with a positioning function, the dropper bottle can be attached to the stopper and inserted in the correct position, thereby enabling the mixing of liquids and powders to be completed quickly and reliably.

[0029] 3. The outer sealing component is securely attached to the outer edge of the mouth, and combined with the exposed upper and hollow design, prevents the stopper from falling off due to impact or external force, while also allowing a dropper bottle to be inserted through the stopper, improving the overall stability of the structure.

[0030] 4. By observing whether the insertion area is depressed, it is possible to directly determine whether the mixing space maintains a negative pressure state, and furthermore, to quickly determine whether the powder is being stored properly. In addition, since the insertion area has a pre-pressure mark, the depressed area is more clearly visible.

[0031] 5. By utilizing the prepressure marks, the direction in which the thin-walled section bursts can be restricted, preventing unexpected bursts in the insertion area. Furthermore, the prepressure marks can reduce the force required for the dropper bottle to insert the stopper.

[0032] Therefore, the configuration of this invention improves the quality of the stored powder, the efficiency of mixing, and the safety of operation, as well as the overall reliability and practicality of this invention. [Explanation of Symbols]
