Description

Technical Field

[0001] The invention relates to the field of packaging, and in particular to a container, which is particularly suitable for containing cosmetics. Background Art

[0002] There are three main ways to package cosmetics at present: the first is blow molding integrated plastic packaging; the second is plastic integrated PE polyethylene packaging material; the third is ampoule bottle. Each of these three methods has some advantages and disadvantages.

[0003] Specifically, in the first method, PE polyethylene plastic pellets are heated and formed by the equipment, directly poured into the cosmetics and then heat-sealed. The entire process is carried out in one device. The first method has three major disadvantages: a. The production process includes high temperature throughout the molding and filling process. For cosmetics that are not resistant to high temperatures (for example, alcohol, etc.), this method cannot be used for canning. b. After the application part of the blow-molded integrated plastic packaging is opened, there are many burrs, the application feel is poor, and there is a tingling sensation. c. The one-time investment in the equipment is large.

[0004] In the second method, after the packaging material is produced, the cosmetics customer fills it by himself and then heat seals it. The plastic is formed in one piece of equipment, and the filling and heat sealing are done by another piece of equipment. The disadvantages of the second method are: the material is harder, there are more burrs after the packaging application part is opened, the application feel is poor, and there is a tingling sensation.

[0005] In the third method, the glass is integrally molded for packaging, and the cosmetics customer fills and heat-seals the bottle. The ampoule is molded by one device, and the filling and heat-sealing are done by another device. There are glass fragments after the ampoule is opened. When applied as cosmetics, it is easy to scratch the applied area. Summary of the invention

[0040] The container disclosed in the present application is mainly used to contain cosmetics and medical devices. The container has a membrane part and a dripper part. The membrane part is composed of two films, and the required container shape is blown out as needed, so that the membrane part is formed with a containing cavity and a filling port. Cosmetics and medical devices can be poured into the filling port of the membrane part and then packaged. The dripper part is formed by thermoforming, and then packaged to the membrane part and communicated with the containing cavity of the membrane part. When in use, the outlet of the dripper part can be opened so that the contents in the container, such as cosmetics and medical devices, flow out from the outlet of the dripper part. The container of the present application is suitable for containing various types of heat-sensitive and heat-insensitive cosmetics and medical devices, such as hyaluronic acid, niacinamide, salicylic acid, through special structural design and process design, and is very convenient to use.

[0041] like Figures 1 to 4 As shown, the container 1 comprises a membrane portion 2 and a dripper portion 3. The dripper portion 3 is heat-sealed to the membrane portion. A fluid channel 4 is provided inside the dripper portion 3. The fluid channel 4 is in fluid communication with the inside of the membrane portion. The membrane portion 3 is provided with a packaging portion 5, a receiving cavity 6 and a filling port 7 in sequence, wherein one end of the receiving cavity 6 is in fluid communication with the packaging portion 5, and the other end is in fluid communication with the filling port 7, so that cosmetics or medical devices can be poured into the receiving cavity through the filling port and discharged from the end where the packaging portion is located.

[0042] The shape of the accommodating cavity 6 is spherical, ellipsoidal, oval or any other suitable shape, and its volume and shape can be set as needed. A first narrowing portion 8 is provided between the filling port 7 and the accommodating cavity, which is narrowed relative to the filling port 7. The filling port 7 can be a section of a passage with an elliptical or circular cross section, and the first narrowing portion 8 can be a section of an elongated pipe, and its cross-sectional area is, for example, 1 / 10 to 1 / 3 of the cross-sectional area of ​​the filling port. As a result, the opening of the filling port 7 can be set to be larger, so as to facilitate filling and sealing after filling.

[0043] The membrane part 2 is made of two layers of film, wherein the encapsulation part 5, the accommodating cavity 6 and the filling port 7 are formed between the two layers of film. The membrane part 2 is made of one material selected from PET, LDPE, PVC, PE, PP, Aclar and PVDC or a composite of two materials, such as PET composite LDPE, PVC composite PE, PP composite PE, Aclar composite PE, or PVDC composite PE. The thickness of the membrane material used to produce the membrane part 2 can be as small as 0.25 mm, so that it feels good to pinch and the contents can be completely squeezed out. The dripper part is made of LDPE, LLDPE, PE, PP, PS, PC. Preferably, the dripper part 3 is made by injection molding.

[0044] A second narrowing portion 9 is provided between the accommodating cavity 6 and the encapsulating portion 5, which is narrowed relative to the encapsulating portion 5 and the accommodating cavity 6. The second narrowing portion 9 may be a slender pipe, and its cross-sectional area is, for example, 1 / 10 to 1 / 3 of the cross-sectional area of ​​the encapsulating portion. Thus, after encapsulation, the fluid in the accommodating cavity 6 may flow through the second narrowing portion 9 and enter the dripper portion 3.

[0045] The dripper part 3 has a dripper 10 and a connecting portion 11, wherein the connecting portion 11 is sealed and connected to the packaging portion 5. Preferably, the connecting portion 11 is heat-sealed to the packaging portion by heat sealing. The connecting portion 11 is provided with at least one circle of protrusions 12 protruding integrally from its outer surface in the radial direction. In the embodiment shown in the figure, there are two circles of protrusions 12. It should be understood that one circle of protrusions or three circles of protrusions, etc. can also be provided. By providing the protrusions 12, the sealing effect when the connecting portion 11 is heat-sealed to the packaging portion 5 can be better and the connection can be more firmly established. The head 13 of the dripper 10 is in the shape of a truncated cone. As a result, the user is more comfortable when using it.

[0046] The fluid channel 4 disposed inside the dripper part 3 is located inside the dripper 10 and the connecting part 11. The fluid of the fluid channel 4 is connected to the accommodating chamber 6. Thus, the fluid in the accommodating chamber can flow out of the dripper 10 via the fluid channel 4. The interior of the dripper part 3 is also provided with a plurality of edges 14 connected to the inner wall of the fluid channel 4 and extending at least along the axial direction of the dripper 10. The edges 14 can extend through the entire dripper 10 and the connecting part 11, or can only extend through the dripper 10. The cross-sections of the plurality of edges 14 are collectively formed into a cross or a trident. Thus, the cross-section of the opening 15 of the dripper 10 is correspondingly a cross or a trident. Thus, the contact area at the connection between the dripper 10 and the gripping part 16 can be reduced, making it easy to break off during use, and reducing the formation of barbs, while controlling the flow rate of the fluid.

[0047] The dripper part 3 also specifically has a gripping portion 16. The gripping portion 16 is located at the other end opposite to the end where the connecting portion 11 is provided, and the gripping portion 16 and the dripper 10 are tearably sealed and connected. Therefore, when in use, the opening 15 of the dripper part 3 can be exposed by tearing off the gripping portion 16, so that the fluid in the accommodating chamber 6 can flow out through the opening 15. The gripping portion 16 has a plurality of convex strips 17 protruding from its outer peripheral surface and extending along its axial direction and spaced apart from each other. Therefore, it is convenient for the user to operate.

[0048] When manufacturing the container of the present application, the manufacturing method thereof comprises the following steps:

[0049] forming a film portion by thermoforming, wherein the film portion has a packaging portion, a receiving cavity and a filling port in sequence, one end of the receiving cavity is in fluid communication with the packaging portion, and the other end of the receiving cavity is in fluid communication with the filling port;

[0050] The dripper part is formed by thermoforming, wherein the dripper part has a dripper and a connecting part, and a fluid channel is provided inside the dripper part, and the fluid in the fluid channel is connected to the accommodating cavity;

[0051] The connecting portion of the dripper and the packaging portion of the membrane portion are connected by heat sealing.

[0052] Here, the thermoforming process of the membrane part includes blow molding, and the thermoforming process of the dripper part includes injection molding and blow molding.

[0053] When filling cosmetics or medical devices, the cosmetics to be filled can be filled into the containing cavity through the sealing part, and then the sealing part is sealed. When in use, the gripping part can be directly screwed off to start using.

[0054] The container of the present application can be filled by cold packaging, thereby being able to fill heat-sensitive cosmetics or medical devices. The dripper part of the container is designed to be smooth, and after the dripper is unscrewed, the application part feels good. Moreover, the container will not drop glass or plastic debris.
