Description

TECHNICAL FIELD

[0001] The product provided by the application belongs to the technical field of cosmetic packaging, and particularly relates to a pump bottle barrier packaging container. BACKGROUND

[0002] In the field of cosmetic industry, more and more natural and effective ingredients are used in the content material, and some ingredients are easy to be oxidized to weaken the effectiveness of the product, so the oxygen barrier property of the packaging container is required to be higher. In the existing invention of the cosmetic pump bottle barrier packaging container, the packaging forms of the vacuum bottle and the double-layer bottle are commonly used, or other ways of combining different packaging forms are used to realize the barrier property of the packaging container. The container forming process is too complex, and the equipment, process and technical level are required to be higher, and more hardware investment such as production molds is required. Due to the high cost, the reliability of the structure and the limitation of the technology, it is not easy to be widely applied. At the same time, most of the barrier packaging is not complete barrier, or there is a blind area of barrier at the bottle cap or the bottle neck. SUMMARY

[0003] The purpose of the application is to overcome the shortcomings of the above packaging technology, provide a structure design which can meet the barrier requirement of different contents and has low cost, and the application can provide more comprehensive barrier packaging for contents with higher barrier requirement.

[0004] A further purpose of the application is to reduce the residual amount of the bottle content.

[0005] To achieve the above purpose and other related purposes, the application provides a pump bottle barrier packaging container, which is characterized by comprising a barrier bag, a pump head, a pump core and a bottle body. The barrier bag is a thin film bag with a ring-shaped cylindrical structure, one end of which is bonded with a hard gasket and the other end is bonded with an elastic sealing ring. A gas permeable hole is formed on the outer wall of the pump core cavity in the pump core, and a liquid guide pipe is installed below. The pump head is assembled with the bottle body, and the sealing gasket of the barrier bag and the pump core cavity together form a closed structure space.

[0006] Further, the barrier bag is folded according to certain rules when not in use to facilitate subsequent use and expansion, and is attached to the inner wall of the bottle body when expanded, surrounding the liquid guide pipe. When not in use, folding can save space and allow the bottle body to store more content material. When in use, it can also fill the entire bottle body, making the entire structure more practical.

[0007] Further, the hard gasket is tightly attached to the sealing gasket, and the elastic sealing ring is tightly sleeved at the lower end of the air hole of the pump core cavity, so that the barrier bag, the sealing gasket of the pump head and the pump core cavity together form a closed structure space, realizing the barrier property of the diaphragm bag.

[0008] Further, the elastic sealing ring is located at the lower side of the vent hole of the cavity of the pump core, so that the elastic sealing ring can better play a role.

[0009] Further, the diameter of the hard washer end has a special relevance to the diameter of the bottle mouth and the thread diameter, and can be used as a universal piece.

[0010] Further, the elastic sealing ring can be used as a universal piece under the condition of meeting special sealing conditions, and the universality of the hard washer and the elastic sealing ring determines that the use environment of the barrier bag has universality.

[0011] Further, the barrier bag keeps the air pressure balance inside and outside the bottle through the air vent hole, so that the pressure balance inside and outside the bottle is ensured, thereby ensuring the normal use effect.

[0012] Further, the gas coming in through the air vent hole is contained in the barrier bag and cannot contact the material, thereby achieving the effect of preventing the material from being oxidized.

[0013] Further, the material of the barrier bag is a composite film, which has good oxygen resistance, moisture resistance, oil resistance and other properties under the joint action of multiple materials, and can effectively protect the quality and shelf life of the product.

[0014] The present application has the following beneficial effects relative to other products in the same field:

[0015] By designing and installing the barrier bag, direct contact between air and the material in the bottle can be effectively avoided, and the barrier property of the product in the bottle is realized.

[0016] Through technical optimization design, the above-mentioned purpose can be achieved by adding additional components without changing the existing container shape and structure, thereby greatly saving the production and manufacturing cost, and the structure is simple and easy to understand, and has universality and can be adjusted for different models of pump bottles.

[0017] Through the design and installation of the barrier bag, the pump head cavity and the material on the bottle wall are gradually pushed into the bottle bottom during use, which is beneficial to the next pumping of the material, reduces the residual amount of the material in the pump bottle structure, and makes the structure suitable for different flowability of the material, and the application range is wider.

[0024] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. The components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0025] In combination with Figures 1-5 the drawings, the present application provides a pump bottle barrier packaging container, mainly composed of a barrier bag 1, a pump head 3, a pump core 2 and a bottle body 4. The barrier bag 1 is a film bag 1.3 designed as an annular cylindrical structure. The opening at one end of the barrier bag 1 is bonded with a hard gasket 1.1, and the opening at the other end is bonded with an elastic sealing ring 1.2. In use, the pump head 3 is assembled with the bottle body 4. The sealing gasket 5 of the barrier bag 1 and the pump head 3 and the pump core cavity 2.2 together form a closed structure space for containing air. The outer wall of the pump core cavity 2.2 in the pump core 2 is also provided with an air hole 2.1 for supplementing air in the above-mentioned structure space. The barrier bag 1 is folded in a certain rule when not in use, which is convenient for subsequent use and expansion. The folding when not in use can save space so that the bottle body 4 can store more content material. When expanded for use, it is attached to the inner wall of the bottle body 4 and surrounds the liquid guide pipe 2.3. When in use, it can also fill the entire bottle body 4, making the entire structure more practical.

[0026] Embodiment 1:

[0027] In combination with Figure 1 and Figure 2 and Figure 5 ​As shown, by designing the hard gasket 1.1 of the barrier bag 1 to be tightly attached and fixed to the sealing gasket, and the elastic sealing ring 1.2 to be tightly sleeved and sealed to the lower end of the air hole at the pump core cavity 2.2, the barrier bag 1, the sealing gasket 5 of the pump head 3, and the pump core cavity 2.2 together form a closed structure space, and the barrier property of the diaphragm bag is exerted. By installing the elastic sealing ring 1.2 at the lower side of the air hole at the pump core cavity, the elastic sealing ring 1.2 can better play a role. Since the diameter of the end of the hard gasket 1.1 has a special correlation with the diameter and thread diameter of the bottle mouth, the diameter can be adjusted according to different calibers of the pump bottle, and can be used in various conditions, so it can be used as a universal part. The elastic sealing ring 1.2 can also be used as a universal part under special sealing conditions, so the hard gasket 1.1 and the elastic sealing ring 1.2 designed in this way both have universality, and the use environment of the barrier bag 1 also has universality.

[0028] In the normal use process, the barrier bag 1 maintains the air pressure balance between the inside and outside of the bottle through the air hole 2.1, so that the pressure balance between the inside and outside of the bottle body 4 is ensured, and the normal use effect of the pump bottle is ensured. The gas entering through the air hole 2.1 is stored in the barrier bag 1 and does not come into contact with the material, thereby preventing the oxidation of the material in the container.

[0029] In the present application, the barrier bag 1 has high universality, and the bottle body 4 can be made into different shapes according to needs, and the design process is not limited to a bottle shape. In the above pump bottle barrier packaging container, the material of the barrier bag 1 is a flexible material that can be rolled and folded, specifically including but not limited to polyvinyl alcohol, polyester, polyimide, and other composite materials. The barrier bag 1 can be rolled and folded and inserted into a bottle body 4 of different shapes through the bottle mouth, or directly fixed on the pump core 2 by compression, together with the pump core 2 and the pump head 3, and directly assembled with the bottle body 4. The outer contour shape of the barrier bag 1 can also be adjusted according to the shape of the bottle body 4 to adapt to different shapes of the bottle body 4, and has universality.

[0030] In the present pump bottle barrier packaging container, the barrier bag 1 is designed to be tightly attached and fixed to the sealing gasket of the pump head 3, and the elastic sealing ring 1.2 is tightly sleeved and sealed to the lower end of the air hole at the pump core cavity 2.2, so that the barrier bag 1, the sealing gasket 5 of the pump head 3, and the pump core cavity 2.2 together form a closed structure space, and the barrier property of the diaphragm bag is exerted. Figure 1 and Figure 3As shown, the cross section of the barrier bag 1 in the present application is tooth-shaped when it is shrunk, which facilitates the connection between the pump core 2, the pump head 3 and the bottle body 4, and the barrier bag 1 does not permeate the material liquid in the bottle body 4. During the use of the pump bottle in the present application, the barrier bag 1 gradually inflates and the volume gradually increases. The material of the barrier bag 1 is foldable and bendable composite material, and the barrier bag 1 is connected with the pump core 2 through the elastic sealing ring 1.2 and the hard gasket 1.1. Therefore, the shape of the inflated barrier bag 1 is annular cylindrical structure, which is in close contact with the inner wall of the bottle body 4 when it is unfolded and expanded, and surrounds the liquid guide pipe 2.3, which can better adapt to different types of bottle bodies.

[0031] In the pump bottle barrier packaging container, the opening end of the barrier bag 1 is bonded with a hard material, which is the hard gasket 1.1, and is installed at the uppermost end of the bottle opening to play a supporting and connecting role while having sealing property. The other opening end is bonded with an elastic material, which is the elastic sealing ring 1.2, and is installed on the outer wall of the pump core 2 below the vent hole to play a sealing and connecting role.

[0032] Example 2:

[0033] In the design process, the use effect of the current pump bottle is optimized without changing the existing packaging container main structure as much as possible. In the present application, a ring-shaped cylindrical structure assembly is used as the barrier bag 1, which is made of composite film bag or barrier material film bag. One end of the barrier bag 1 is bonded with the hard gasket 1.1, and the other end of the barrier bag 1 is bonded with the elastic sealing ring 1.2. When the pump bottle is initially filled with material, the barrier bag is folded in a certain way. When the material in the pump bottle is continuously consumed, the barrier bag is unfolded subsequently.

[0034] When assembling, the barrier bag 1 designed as a ring-shaped cylindrical structure assembly is pre-assembled with the pump head 3. The assembly form is as follows: the end of the hard gasket 1.1 of the barrier bag 1 is tightly attached to the sealing gasket, and the end of the elastic sealing ring 1.2 is tightly attached to the lower end of the vent hole on the pump core cavity 2.2 and the pump core cavity 2.2. Since the thread diameter of the pump bottle opening and the bottle neck have a certain universality, the diameter of the end of the hard gasket 1.1 can be adjusted to adapt to different models of pump bottles, so that the hard gasket 1.1 has a certain universality and can be used as a universal part. The elastic sealing ring 1.2 of the barrier bag 1 has a certain elasticity and can be used as a universal part under certain sealing conditions. Therefore, the universality of the two ends of the barrier bag 1 determines that the use conditions of the barrier bag 1 also have universality, which can be applied to more use environments.

[0035] After the pump head 3 and the bottle body 4 are assembled, the barrier bag 1, the sealing gasket 5 on the pump head 3 and the pump core cavity 2.2 jointly form a closed structure space, in the process of using the pump head 3, as the material in the bottle is sprayed out, the negative pressure is gradually formed in the bottle, the gas enters through the air hole 2.1 on the pump core cavity 2.2 to keep the air pressure balance between the inside and outside of the bottle, the gas entering through the air hole 2.1 is always contained in the barrier bag 1 and cannot contact the material, thereby preventing the material from deteriorating due to oxidation reaction, as the use amount of the material increases, the gas entering the barrier bag 1 gradually increases, the folded barrier bag 1 is gradually unfolded and expanded, and the barrier bag 1 gradually approaches the pump head 3 cavity and the bottle inner wall, the material on the pump head 3 cavity and the bottle wall is gradually pushed into the bottle bottom, which is beneficial to the material being pumped out next time and reduces the residual amount of the material in the bottle.

[0036] Embodiment 3:

[0037] In the working mode of the present application, as the content material is sprayed out in the process of using the pump head 4, the negative pressure is gradually formed in the bottle, the pump core air hole 2.1 on the pump core 2 wall enters the gas to keep the air pressure balance between the inside and outside of the bottle. The gas entering through the pump core air hole 2.1 is introduced into the annular barrier bag 1 and cannot contact the material. As the use amount increases, the gas entering the annular barrier bag 1 gradually increases, which causes the annular barrier bag 1 in the folded state during filling to gradually unfold and approach the pump bottle inner wall and the pump core 2 outer wall. The material on the pump bottle inner wall and the pump core 2 outer wall is pushed into the bottle bottom along with the expansion of the annular barrier bag 1, which is beneficial to the material being pumped out next time and reduces the residual amount of the material on the pump bottle inner wall and the pump core 2 outer wall.

[0038] The present application increases the inner packaging bag part barrier bag 1 on the basis of the existing main body pump bottle packaging structure to solve the barrier problem of the material in the bottle and the gas entering the bottle, through the modification on the basis of the original, the cost and development time are saved; through the design of the barrier bag 1, the problem that the material is hung on the wall due to the too high viscosity of the material can be solved to a certain extent, the problem that the material cannot be pumped out by the conventional pump bottle structure container is solved, and the barrier is realized; since the existing container shape and main structure are not changed, the above-mentioned purposes are realized by increasing and modifying the parts, the production and manufacturing cost is greatly saved, and such design has universality and wider application range; the barrier bag 1 of the structure design can reduce the residual amount of the material on the inner wall of the packaging container of the pump bottle structure, since the barrier bag 1 has the ductility, the structure is suitable for different flowability of the material and has a wider use range.

[0039] In general, the packaging structure provided by the present application is made of a composite film bag or a barrier material film bag to form a ring-shaped cylindrical structure assembly, one end is bonded with a hard material, the other end is bonded with an elastic material, and is folded in a certain rule, the ring-shaped cylindrical structure assembly is pre-assembled with the pump head 3, and the assembly form is as follows: the hard material end is tightly attached with the sealing gasket, and the elastic material end is tightly sleeved with the lower end of the air hole at the pump core cavity 2.2. After the pump head 3 is assembled with the bottle, the film bag 1.3, the sealing gasket 5 of the pump head 3 and the pump core cavity 2.2 jointly form a closed structure space, through the design and installation of the barrier bag 1, when in use, the material in the pump head cavity and the bottle wall is gradually pushed into the bottom of the bottle, which is beneficial to the next pumping of the material, reduces the residual amount of the content material in the pump bottle structure, so that the structure is suitable for different flowability of the material, and the application range is wider.

[0040] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.
