Description

Technical Field

[0001] This utility model relates to the field of freeze-dried product packaging technology, specifically to a packaging tube. Background Technology

[0002] In the fields of cosmetics and pharmaceuticals, freeze-drying technology is widely used to prepare freeze-dried formulations, such as common freeze-dried spheres and freeze-dried powders. These formulations offer significant advantages because they can remove moisture under low temperature and low pressure conditions, effectively preserving the stability of active ingredients, extending product shelf life, and facilitating transportation and storage. Freeze-dried formulations need to be mixed with a specific solvent (such as water, serum, or other specialized solutions) before use.

[0003] Currently, common packaging methods typically involve placing the lyophilized formulation and solvent in separate containers. For example, the lyophilized formulation might be packaged in a vial, while the solvent is stored separately in another tube. This separate packaging method increases packaging material and production costs. Furthermore, users must open both packages separately to mix them, which is inconvenient. Additionally, when traveling or on business trips, users need to carry both packages, which is cumbersome and prone to loss. Therefore, existing packaging methods still have significant shortcomings in terms of economy, convenience, and user experience. Utility Model Content

Detailed Implementation

[0018] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.

[0021] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0022] Example 1:

[0023] like Figure 1-5As shown, this embodiment provides a packaging tube, which includes a first tube body 1, a second tube body 2, and an intermediate tube 3. The first tube body 1 stores a first material (not shown in the figure), and the second tube body 2 stores a second material (not shown in the figure). The first material can be a lyophilized formulation, and the second material corresponds to a solvent solution that can be mixed and dissolved with the lyophilized formulation; or, the second material is a lyophilized formulation, and the first material is a solvent solution that can be mixed and dissolved with the lyophilized formulation.

[0024] Furthermore, the intermediate tube 3 is disposed between the first tube body 1 and the second tube body 2. The intermediate tube 3 includes a support section 31 and annular first connecting section 32 and second connecting section 33 located on both sides of the support section 31. The support section 31 protrudes radially from the first connecting section 32 and the second connecting section 33, and can support and limit the tube walls of the first tube body 1 and the second tube body 2. The first connecting section 32 extends into the first tube body 1 and is sealed to the first tube body 1. The connection method can be selected, but is not limited to, threaded connection, bonding, welding, etc. The second connecting section 33 extends into the second tube body 2 and is sealed to the second tube body 2. The connection method can be selected, but is not limited to, threaded connection, bonding, welding, etc. An isolation member 34 is also integrally formed on the intermediate tube 3. The isolation member 34 includes a breaking rod 341 extending toward the inside of the second tube body 2.

[0025] Furthermore, the first tube 1 and the second tube 2 are made of transparent material, such as transparent plastic, and the second tube 2 is made of flexible material. In the initial state, the first material in the first tube 1 and the second material in the second tube 2 are sealed and separated by the separator 34; when needed, because the second tube 2 is made of flexible material, the breaking rod 341 can be pried to one side by fingers, thereby breaking the seal of the separator 34, and allowing the first material and the second material to mix.

[0026] Thus, the packaging tube provided in this embodiment simultaneously stores both lyophilized formulation and solvent, with the lyophilized formulation and solvent stored in different locations within the tube. They are mixed only when needed, satisfying the requirements of separate storage and mixed use. When users are out and about, they only need to carry one packaging tube, making it convenient to carry. Moreover, mixing can be performed simply by bending the breaking rod 341, making it easy to use. Furthermore, the packaging tube of this embodiment only includes three components: a first tube 1, a second tube 2, and an intermediate tube 3. These three components can be made of plastic and manufactured through injection molding, blow molding, or other methods, resulting in low cost and ease of automated processing. The first tube 1 and the second tube 2 are preferably made of transparent material, allowing users to clearly see the internal materials. In addition, the separator 34 is integrally formed on the intermediate tube 3 of this embodiment, providing a good sealing effect.

[0027] like Figure 4 As shown, in this embodiment, the first tube 1 has an openable opening 11 to allow the mixed liquid to be discharged for use. The opening 11 can be closed by a head integrally formed on the first tube 1, or by a cap threaded to the end of the first tube 1; this embodiment does not impose any limitations on this. Of course, in other embodiments, the opening 11 can also be provided on the second tube 2.

[0028] like Figure 4-5 As shown, the isolation member 34 in this embodiment includes a breaking rod 341 and an isolation plate 342. The isolation plate 342 is integrally formed at the end of the second connecting section 33, i.e., the lower end in the figure, and the breaking rod 341 is integrally formed on the isolation plate 342. Further, a thinning line 343 is formed on each of the upper and lower sides of the isolation plate 342. When the breaking rod 341 is bent, the thinning line 343 can be broken, thereby opening the end of the second connecting section 33 and forming a channel with a larger area, which is conducive to the full and rapid mixing of the first material and the second material.

[0029] Preferably, in this embodiment, the breaking rod 341 is not located at the center of the isolation plate 342, but is offset from the center and located on the side near the inner wall of the second tube 2; this makes it easier for the user to pry the breaking rod 341 and allows for more space to accommodate the freeze-dried preparation. The lower end of the breaking rod 341 can also be designed in geometric, fruit, or cartoon shapes as needed.

[0030] like Figure 2-4 As shown, the first material in this embodiment is preferably a solvent liquid, and the second material is a lyophilized formulation; an opening 11 is formed on the first tube 1. Further, a stopper plate 4 is provided on the side of the isolation plate 342 facing the first tube 1, and a plurality of filter holes 41 are formed on the stopper plate 4; the stopper plate 4 can be made of plastic or rubber, and can be inserted from the upper end of the intermediate tube 3 and held at a set height position. The lyophilized formulation can be filtered through the stopper plate 4. For example, when the lyophilized formulation is a lyophilized ball, the stopper plate 4 can prevent large pieces of undissolved lyophilized formulation from escaping.

[0031] Furthermore, in this embodiment, a support rod 344 is integrally formed on the side of the isolation plate 342 facing the first tube 1. The support rod 344 can limit the position of the stopper plate 4 during installation, which facilitates the installation of the stopper plate 4. In addition, when the breaking rod 341 is pried open, the support rod 344 can also support between the stopper plate 4 and the isolation plate 342 to prevent the filter holes 41 on the stopper plate 4 from being blocked by the isolation plate 342 when the liquid is discharged in reverse.

[0032] Preferably, the intermediate tube 3 in this embodiment is made of a non-transparent material and is marked, for example, different colors can be used to identify product series; and the intermediate tube 3 is preferably made of a rigid material to facilitate better support. The first tube body 1 can be made of a rigid material; or it can be made of a soft material to facilitate squeezing out liquid and mixing; or it can be made of a rigid upper part and a soft lower part, which can be achieved by different thicknesses, etc.

[0033] As can be seen from the above, the packaging tube provided in this embodiment can be used as a single-use product or a non-single-use product such as a weekly or monthly disposable product. It can store the solvent and lyophilized preparation separately, and it is also convenient to mix and carry. In addition, it has a small number of parts, low cost, good sealing effect, and a series of labels that are easy to visualize.

[0034] Example 2:

[0035] This embodiment is a further improvement on Embodiment 1.

[0036] like Figure 6-7 As shown, the packaging tube in this embodiment also includes a sealing member 5, which is sealed at the end of the first connecting section 32. Figure 6 At the upper middle end, a push rod 51 extends from the sealing member 5 toward the inside of the first tube 1. Specifically, the sealing member 5 is preferably made of plastic and includes a sealing plate 52 and a push rod 51. The sealing plate 52 is sealed to the first connecting section 32. If necessary, a sealing ring can be provided on the outer periphery of the insertion section of the sealing plate 52. The push rod 51 is integrally formed on the sealing plate 52. In the initial state, a first material is placed between the first tube 1 and the sealing plate 52, and a third material is placed between the sealing plate 52 and the separator 34. The first material and the third material are different solvents or liquid preparations. The separator 34 and the second tube 2 contain lyophilized preparations.

[0037] In the initial state, the first material and the third material are sealed and separated by the closure 5, and the third material and the second material are sealed and separated by the separator 34. Both the first tube 1 and the second tube 2 are made of flexible material. In use, the push rod 51 can be bent to break the seal of the closure 5, allowing the first material and the third material to mix; then, the breaking rod 341 can be bent to break the seal of the separator 34, allowing the mixed liquid to continue mixing with the second material.

[0038] In some cases, the mixed storage of different liquid formulations can lead to performance instability, thereby affecting the efficacy; for example, prolonged mixed storage of acidic substances and protein-based substances can result in reduced activity and efficacy. Therefore, this embodiment improves the dual-lumen packaging tube into a triple-lumen packaging tube, which enables the separate storage and mixed use of the first liquid formulation, the second liquid formulation, and the lyophilized formulation.

[0039] Preferably, in this embodiment, the push rod 51 is also eccentrically positioned on one side for easy prying; and during assembly, it is preferably positioned on the same side as the breaking rod 341, for example... Figure 6 On the left side of the middle tube. Preferably, in this embodiment, the middle tube 3 is also made of a non-transparent rigid material, and markings may also be set on the middle tube 3 as needed.

[0040] Example 3:

[0041] This embodiment is a further improvement on embodiment two.

[0042] like Figure 8-9 As shown, the packaging tube in this embodiment also includes a sheath 6. The sheath 6 includes a fastening part 61, a first protective part 62, and a second protective part 63. The fastening part 61 is an open annular shape, used to engage with the side wall of the support section 31 of the intermediate tube 3. Specifically, a slot can be provided on the outer side wall of the support section 31, and a buckle can be provided on the inner side wall of the fastening part 61 to achieve the engagement of the two.

[0043] Furthermore, the first protective part 62 extends toward the second tube body 2, and the cross-section of the first protective part 62 is fan-shaped and positioned close to the eccentrically positioned breaking rod 341. The first protective part 62 is made of hard plastic relative to the second tube body 2, which can prevent the breaking rod 341 from being prematurely damaged during transportation or accidental drop. In use, the protective sleeve 6 is first peeled off, and then the breaking rod 341 is broken for use.

[0044] Similarly, the second protective part 63 extends toward the first tube body 1, and the cross-section of the second protective part 63 is also fan-shaped, and it is positioned close to the eccentrically positioned push rod 51. The second protective part 63 is made of hard plastic relative to the first tube body 1, which can prevent the push rod 51 from being damaged prematurely during transportation or accidental drop. In use, the protective sleeve 6 is peeled off first, and then the push rod 51 is broken for use.

[0045] In other embodiments, such as Embodiment 1, only the first extension 62 may be provided to protect the damage rod 341.

[0046] Example 4:

[0047] This invention does not limit the shape of the packaging tube; the overall shape of the packaging tube can be any shape, for example, except... Figure 1 In addition to the shape shown, other designs can also be used. Figure 10 The internal structure of the arc-shaped tube shown can be implemented with reference to the aforementioned embodiments, and will not be described in detail here.

[0048] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
