[0001] The utility model relates to the technical field of packaging bottles, in particular to an anti-extrusion packaging bottle. Background Art

[0002] With the booming cosmetics industry, the variety of cosmetics on the market is increasing. Accordingly, the bottles used to hold cosmetics are also constantly innovating. Currently, common cosmetic bottles are categorized by dispensing method: pour-type, press-type, and squeeze-type. Among the various cosmetic bottles, squeeze-type bottles are highly favored due to their ease of use and ability to better control dispensing volume.

[0003] However, existing squeeze-out bottles are susceptible to deformation during transportation or carrying, leading to leakage of the contents. Therefore, there is an urgent need for a squeeze-resistant bottle that can protect the contents without affecting access to the contents, thereby improving user satisfaction. Utility Model Content

[0004] In view of the deficiencies of the existing technology, the present invention proposes an anti-squeeze packaging bottle, which can provide protection for the substance in the packaging bottle without affecting the material removal, thereby improving user satisfaction.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A squeeze-resistant packaging bottle comprises an outer cover and an inner liner; the outer cover covers the outer wall of the inner liner, the outer cover is made of a hard material, and the outer cover is provided with a pressing portion for pressing the inner liner; the inner liner is provided with an inner liner discharge port for discharging material, and the outer wall of the inner liner is made of a flexible material.

[0007] Preferably, the inner liner is provided with an elastic portion, and when the pressing portion is pressed toward the inner liner, the elastic portion is compressed.

[0008] Preferably, the elastic portion is integrally formed with the inner container, and the elastic portion includes a plurality of grooves arranged in parallel along the outer wall of the inner container, and the plane formed by the grooves is parallel to the plane where the pressing portion is located.

[0009] Preferably, the outer wall of the inner container is made of flexible plastic or silicone.

[0010] Preferably, the outer cover is hollowed out to provide an accommodating hole for accommodating the pressing part, the pressing part includes a fixed end and a free end, the fixed end is connected to the outer cover, and the free end is an extension of the fixed end toward the accommodating hole, the pressing part is made of a hard material with elasticity, and the free end can be moved to abut against the outer wall of the inner liner.

[0011] Preferably, the pressing portion and the outer cover are integrally formed.

[0012] Preferably, the outer cover is made of hard plastic or rigid metal.

[0013] Preferably, it further comprises a discharging mechanism, which is detachably connected to the outer cover and the inner container respectively, and the discharging mechanism is provided with a discharging channel, which is communicated with the discharge port of the inner container.

[0014] Preferably, a sealing cover is further included, and the sealing cover is connected to the discharge mechanism to seal the discharge port of the discharge channel.

[0015] By adopting the above technical solution, the utility model has the following beneficial effects:

[0016] 1. The outer cover covers the outer wall of the inner liner and is made of hard material. During transportation or carrying, it can provide good protection for the inner liner and effectively prevent external force from squeezing and causing deformation of the packaging bottle and leakage of substances. The pressing part on the outer cover is convenient for users to press the inner liner so that the substance can be discharged smoothly from the inner liner outlet, which is easy to operate.

[0017] 2. The inner liner is equipped with an elastic portion. When external force acts on the pressing portion, the pressure is transmitted to the outer wall of the inner liner through the pressing portion, causing the elastic portion to compress. The compression of the elastic portion reduces the internal space of the inner liner body, thereby squeezing out the material inside the liner. The degree of compression of the elastic portion can be adjusted according to the pressure applied by the user, thereby achieving precise control of the discharge volume. The user can press the pressing portion lightly or firmly according to actual needs to obtain the desired discharge volume, improving the convenience and flexibility of use.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," "third," and "fourth," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0031] See also Figure 1-Figure 4 The embodiment of the utility model discloses an anti-squeeze packaging bottle, comprising an outer cover 1 and an inner liner 2; the outer cover 1 covers the outer wall of the inner liner 2, and the outer cover 1 is made of a hard material. The outer cover 1 is provided with a pressing portion 11 for pressing the outer wall of the inner liner 2; the inner liner 2 is provided with an inner liner discharge port 21 for discharging materials, and the outer wall of the inner liner 2 is made of a flexible material. Specifically, during transportation or carrying, when squeezed by external force, the outer cover 1 first bears most of the force, thereby reducing the direct pressure on the inner liner 2 and effectively preventing the packaging bottle from deforming and the leakage of substances. At the same time, the design of the pressing portion 11 allows the user to easily control the discharge of substances from the inner liner discharge port 21 by pressing, which improves the convenience of operation and is conducive to improving user satisfaction.

[0032] See also Figure 1 as well as Figure 2 The inner liner 2 is provided with an elastic portion 22. When the pressing portion 11 is not squeezed, the pressing portion 11 abuts against the inner liner 2; when the pressing portion 11 is squeezed toward the inner liner 2, the elastic portion 22 is compressed. Specifically, the user can apply different amounts of pressure according to actual needs. When pressed lightly, the elastic portion 22 is slightly compressed, the internal space of the inner liner 2 changes little, and the discharge amount is small; when pressed hard, the elastic portion 22 is greatly compressed, the internal space of the inner liner 2 is significantly reduced, and the discharge amount increases, thereby achieving precise control of the discharge amount. After releasing the pressing portion 11, the elastic portion 22 quickly returns to its original shape due to its elasticity, so that the packaging bottle can be ready for the next squeezing operation at any time, improving the convenience and flexibility of use.

[0033] See also Figure 2The elastic part 22 is integrally formed with the inner liner 2, and the elastic part 22 includes a plurality of grooves arranged in parallel along the outer wall of the inner liner 2, so that the elastic part 22 can withstand the external force more evenly and deform when subjected to the pressure of the pressing part 11. The plane formed by the grooves is parallel to the plane where the pressing part 11 is located. When the pressing part 11 applies pressure, the pressure can act vertically on the elastic part 22, making the compression of the elastic part 22 more efficient. In this embodiment, the outer wall of the inner liner 2 is made of flexible plastic or silicone. This material has good elasticity and flexibility and can deform when subjected to external force, providing more space for the compression of the elastic part 22. When the pressing part 11 is pressed, the flexible outer wall of the inner liner 2 will deform first, transferring the pressure to the elastic part 22. Under the action of pressure, the elastic part 22 shrinks inward along the direction of the groove, thereby effectively reducing the internal space of the inner liner 2 and squeezing out the substance therein.

[0034] The outer cover 1 is provided with a receiving hole 13 for accommodating the pressing portion 11. The pressing portion 11 includes a fixed end 111 and a free end 112. The fixed end 111 is connected to the outer cover 2, and the free end 112 is an extension of the fixed end 111 toward the receiving hole 13. The pressing portion 11 is made of a hard, elastic material, and the free end 112 can move to abut the outer wall of the inner liner 2. In this embodiment, there are two receiving holes 13 and two pressing portions 11, and the pressing portions 11 are symmetrically arranged on the outer cover 2.

[0035] The pressing portion 11 can be made of soft rubber or silicone, so that the user can squeeze it more easily. In actual application, the pressing portion 11 needs to be designed according to the actual application situation.

[0036] In some other embodiments, the pressing portion 11 is integrally formed with the outer cover 1. The pressing portion 11 and the outer cover 1 are both made of elastic hard plastic.

[0037] In some other embodiments, the outer cover 1 is made of hard plastic or rigid metal, and the pressing portion 11 is made of elastic hard plastic.

[0038] See also Figure 2 as well as Figure 3 A squeeze-resistant packaging bottle also includes a discharge mechanism 3, which is respectively connected to the outer cover 1 and the inner liner 2, so that the outer cover 1 can be covered on the outer wall of the inner liner 2, and the discharge mechanism 3 is provided with a discharge channel 31, which is connected to the discharge port 21 of the inner liner.

[0039] Further, see Figure 2 as well as Figure 3The outer wall of the inner liner discharge port 21 is provided with external threads 23, and the inner wall of the discharge channel 31 is provided with internal threads 32. The discharge mechanism 3 and the inner liner 2 are threadedly connected via the external threads 23 and the internal threads 32. In other words, the discharge mechanism 3 and the inner liner 2 are detachably connected via this threaded connection. When the external threads 23 and the internal threads 32 are screwed together, the two fit tightly together. During use, even when subjected to external forces, the threaded connection remains secure and will not easily loosen.

[0040] Further, see Figure 3 The discharge channel 31 is provided with an inner sealing ring 33, which is arranged on one side of the discharge channel 31 and is located on the same side as the discharge port of the discharge channel 31. When the external thread 23 is connected to the internal thread 32, the side wall of the inner tank discharge port 21 is squeezed between the inner side of the discharge channel 31 and the inner sealing ring 33. The inner sealing ring 33 plays a sealing role in this process, which is beneficial to enhance the sealing performance of the connection between the discharge mechanism 3 and the inner tank 2 and prevent material leakage.

[0041] Further, see Figure 3 The outer cover 1 is provided with a groove latch 12, and the outer side of the discharge mechanism 3 is provided with a protrusion latch 34. The outer cover 1 and the discharge mechanism 3 are engaged by the protrusion latch 34 and the groove latch 12. When the inner liner 2 needs to be replaced, the engagement between the discharge mechanism 3 and the outer cover 1 is released, and then the threaded connection between the discharge mechanism 3 and the inner liner 2 is separated by rotating. The old inner liner 2 can be easily removed and replaced with a new one, thus making it easy to replace the inner liner 2.

[0042] Further, see Figure 2 as well as Figure 3 A limiting ring 35 is provided on the outer wall of the discharging mechanism 3; when the protruding position 34 is engaged with the groove position 12, the outer cover 1 abuts against the limiting ring 35, thereby improving the overall stability of the packaging bottle.

[0043] See also Figure 2 as well as Figure 3 The squeeze-resistant bottle also includes a sealing cap 4 connected to the discharge mechanism 3 to seal the discharge opening of the discharge channel 31. When connected to the discharge mechanism 3, the sealing cap 4 forms a closed space, isolating the discharge opening of the discharge mechanism 3 from the external environment. During storage and transportation, the sealing cap 4 prevents external contaminants from entering the bottle, maintaining the quality of the contents. Furthermore, when the bottle is not in use, the sealing cap 4 prevents leakage of the contents, enhancing the safety of the bottle.

[0044] Further, see Figure 2 as well as Figure 3The outer wall of the discharge mechanism 3 is provided with a snap-fitting ridge 36, and the inner wall of the sealing cover 4 is provided with a snap-fitting groove 41. The discharge mechanism 3 and the sealing cover 4 are snap-fitted together by the snap-fitting ridge 36 and the snap-fitting groove 41, so that the sealing cover 4 is tightly connected to the discharge mechanism 3. When the snap-fitting ridge 36 and the snap-fitting groove 41 are snap-fitted together, the two are tightly matched to form a sealed connection structure. During use, the sealing cover 4 will not fall off easily and can effectively maintain the sealing state of the discharge port. This connection method improves the sealing performance of the sealing cover 4 and ensures the safety of the substances in the packaging bottle. Furthermore, a sealing plug 42 is provided in the sealing cover 4. The sealing plug 42 is embedded in the discharge port of the discharge channel 31 to seal the discharge port of the discharge channel 31, thereby ensuring good sealing of the packaging bottle.

[0045] See also Figure 4 In some other embodiments, a folding connection is provided between the discharge mechanism 3 and the sealing cover 4, and the discharge mechanism 3 and the sealing cover 4 are connected by the folding connection. This folding connection between the discharge mechanism 3 and the sealing cover 4 prevents the sealing cover from being easily lost. To facilitate opening the sealing cover, a flip-opening recess 37 can be provided on the outer wall of the discharge mechanism 3.

[0046] The implementation principle of this embodiment is:

[0047] The squeeze-resistant packaging bottle's outer cover 1 encloses the inner liner 2. During transport or transportation, the outer cover 1 primarily withstands external forces, protecting the inner liner 2 from deformation and leakage. The pressing portion 11 on the outer cover 1 allows for easy squeezing. The elastic portion 22 of the inner liner 2 adjusts its compression according to the user's pressure, precisely controlling the amount of material discharged. Once the pressing portion 11 is released, the elastic portion 22 quickly returns to its original shape, ensuring ease of use for the next time.

[0048] The discharge mechanism 3 is tightly coupled to the inner container 2 via a threaded connection, and the inner sealing ring 33 further enhances the sealing of the connection. The outer cover 1 is engaged with the discharge mechanism 3 via the groove engaging position 12 and the protruding engaging position 34, and the overall stability is enhanced by the limiting ring 35. The sealing cover 4 is engaged with the discharge mechanism 3 via the engaging ridge 36 and the engaging groove 41, and the internal sealing plug 42 is embedded in the discharge port of the discharge channel 31 to achieve a good seal, ensuring the quality and safety of the material. In other embodiments, the discharge mechanism 3 and the sealing cover 4 are connected via a folding connection to prevent the sealing cover 4 from being lost, and a recessed position 37 for the flip cover is provided for easy opening.

[0049] The outer cover 1, the inner liner 2, the discharge mechanism 3 and the sealing cover 4 are detachable, which enables convenient replacement of the inner liner 2, improves the recycling rate of the outer cover 1, the discharge mechanism 3 and the sealing cover 4, saves material costs and is more environmentally friendly.
