Abstract
Description
Technical Field
[0001] This application relates to the field of beverage packaging bottle technology, and in particular to an AD calcium beverage packaging bottle suitable for aseptic cold dispensing. Background Technology
[0002] With the general improvement of people's living standards, dairy beverages are widely used in daily life. They suit the tastes of most people; for example, AD calcium milk is very popular. Aseptically packaged dairy beverages undergo strict aseptic processing and are filled in a sterile environment, greatly reducing the risk of microbial contamination and extending their shelf life and flavor.
[0003] In the present technology, ordinary beverage bottles are usually made of transparent materials, which cannot effectively block light. This causes beverages containing photosensitive active substances such as vitamins to oxidize and deteriorate during storage and shelf life, resulting in flavor degradation and loss of nutrients, affecting the stability of product quality. At the same time, ordinary bottle caps rely on a single threaded sealing structure, which is difficult to compensate for the tiny gaps caused by the thermal expansion and contraction of materials when transported in environments with large temperature differences. This can easily lead to chronic leakage, which not only contaminates the appearance of the packaging but also increases the quality risk.
[0004] In other words, existing technologies have the following technical problems: ordinary beverage bottles are prone to oxidation and spoilage when packaging beverages containing photosensitive active substances such as vitamins. Therefore, to address the above problems, a packaging bottle for AD calcium beverages suitable for aseptic cold-packing is proposed. Summary of the Invention
[0005] This embodiment provides an AD calcium beverage packaging bottle suitable for aseptic cold containers to solve the problem that ordinary beverage packaging bottles in the prior art are prone to oxidation and deterioration when packaging beverages containing photosensitive active substances such as vitamins.
[0006] According to one aspect of this application, an AD calcium beverage packaging bottle suitable for aseptic cold dispensing is provided, the AD calcium beverage packaging bottle suitable for aseptic cold dispensing comprising:
[0007] The bottle body is narrower at the top and wider at the bottom, with a bottle neck on the top and a filling mark below the bottle neck.
[0008] The bottle body has a gripping groove on its middle surface, which surrounds the bottle body.
[0009] The bottom of the bottle is provided with an inwardly recessed anti-swelling groove;
[0010] The entire outer surface of the bottle is covered with a semi-transparent layer.
[0011] Furthermore, the grip groove is formed by eight longitudinal reinforcing ribs surrounding the surface of the bottle, and four transverse reinforcing ribs surround the surface of the bottle from top to bottom.
[0012] Furthermore, the anti-swelling groove is centered on the bottle shaft, with the bottom of the bottle concave inward to form a triangular groove that is equidistantly surrounding the bottle shaft.
[0013] Furthermore, the filling mark is a rectangular transparent strip that protrudes from the bottle body.
[0014] Furthermore, it also includes a bottle cap, which is threadedly connected to the bottle neck thread via a threaded groove; specifically, the bottle neck thread is located on the outer wall of the bottle neck, and the threaded groove is located on the inner wall of the bottle cap.
[0015] Furthermore, the translucent layer is milky white and translucent.
[0016] Furthermore, a sealing gasket is fixedly connected to the inner wall of the bottle cap, and the sealing gasket fits the bottle opening.
[0017] Furthermore, an auxiliary sealing part is provided between the bottle cap and the bottle mouth, which is used to perform secondary sealing at the gap between the bottle mouth and the bottle cap.
[0018] Furthermore, the auxiliary sealing part includes a sealing ring, a contact layer, and an elastic layer. The sealing ring is fixedly disposed at the arc-shaped wall of the bottle mouth, and the outer wall of the sealing ring is conical. The contact layer is fixed to the bottom of the bottle cap by the elastic layer, and the contact layer is provided with a contact surface that fits against the sealing ring.
[0019] In order to solve the problem that ordinary beverage packaging bottles are prone to oxidation of liquid due to light transmission during use, this application designs a semi-transparent layer through the above embodiments. By setting the semi-transparent layer, the overall light transmission of the bottle can be reduced, thereby preventing the liquid from oxidizing and protecting the flavor. In order to avoid leakage caused by squeezing or temperature changes during transportation, an auxiliary sealing part is further designed. By setting the auxiliary sealing part, the gap can be effectively compensated and leakage can be avoided. Attached Figure Description

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0035] Please see Figure 1-7 As shown, an AD calcium beverage packaging bottle suitable for aseptic cold dispensing includes:
[0036] Bottle body 1, which is narrower at the top and wider at the bottom, has a bottle neck 101 on it, and a filling mark 4 is provided below the bottle neck 101.
[0037] The bottle body 1 has a gripping groove 2 on its middle surface, and the gripping groove 2 surrounds the bottle body 1.
[0038] The bottom of the bottle body 1 is provided with an inwardly recessed anti-swelling groove 3;
[0039] The entire outer surface of the bottle body 1 is covered with a translucent layer 103;
[0040] Through the above technical solution, the semi-transparent layer 103 reduces the overall light transmission of the bottle body 1, thereby preventing the liquid from oxidizing and preserving the flavor. Furthermore, to prevent leakage caused by compression or temperature changes during transportation, an auxiliary sealing part 9 is designed. The auxiliary sealing part 9 effectively compensates for gaps and prevents leakage.
[0041] The grip groove 2 is formed by eight longitudinal reinforcing ribs 7 surrounding the surface of the bottle body 1, and four transverse reinforcing ribs 8 surround the surface of the bottle body 1 from top to bottom.
[0042] The anti-swelling groove 3 is centered on the bottle shaft 5, with the bottom of the bottle recessed inward to form a triangular groove that surrounds the bottle shaft 5 at equal intervals.
[0043] The filling mark 4 is a rectangular transparent strip that protrudes from the bottle body 1. Preferably, the distance from the bottle mouth 101 to the filling mark 4 is 30mm. Here, the mark means that milk is filled to 450±7g and water is filled to 441ml.
[0044] It also includes a bottle cap 6, which is threadedly connected to the bottle mouth thread 102 via a threaded groove 602; specifically, the bottle mouth thread 102 is located on the outer wall of the bottle mouth 101, and the threaded groove 602 is located on the inner wall of the bottle cap 6.
[0045] The translucent layer 103 is milky white and translucent. Preferably, the translucent layer 103 is made of PET material with added milky white pigment. The bottle body 1 is made of PET material. Through this technical solution, the milky white and translucent bottle body 1 can effectively reduce the overall light transmittance, thereby preventing the liquid from oxidizing and protecting the flavor. Furthermore, the filling mark 4 can be set to facilitate the positioning of the filling liquid during filling.
[0046] Preferably, the thickness of the milky white translucent layer 103 is about 0.1 to 0.5 mm; the haze value of the translucent layer 103 is preferably 60% to 95%, more preferably 80% to 90%; the amount of milky white pigment added accounts for about 1% to 5% of the total weight of the PET material to achieve the required light transmittance and color effect; the wall thickness of the PET substrate of the bottle body 1 is about 0.25 to 0.5 mm; the translucent layer 103 is tightly wrapped and fixed to the outer surface of the bottle body 1 by co-extrusion molding or overmolding process.
[0047] A sealing gasket 601 is fixedly connected to the inner wall of the bottle cap 6. The sealing gasket 601 fits against the bottle mouth 101. With this technical solution, after the bottle cap 6 is tightened, the sealing gasket 601 can fit against the top of the bottle mouth 101 to achieve the sealing function. The sealing gasket 601 is made of food-grade elastic material, preferably silicone or butyl rubber, and its thickness is about 0.5 to 2.0 mm.
[0048] An auxiliary sealing part 9 is provided between the bottle cap 6 and the bottle mouth 101. The auxiliary sealing part 9 is used to perform secondary sealing at the gap between the bottle mouth 101 and the bottle cap 6.
[0049] The auxiliary sealing part 9 includes a sealing ring 901, a contact layer 902, and an elastic layer 903. The sealing ring 901 is fixedly disposed at the arc-shaped wall of the bottle mouth 101, and the outer wall of the sealing ring 901 is conical. The contact layer 902 is fixed to the bottom of the bottle cap 6 through the elastic layer 903. The contact layer 902 is provided with a contact surface that fits against the sealing ring 901. Through this technical solution, when the bottle cap 6 is tightened after filling, the elastic layer 903 is in a compressed state, causing the contact layer 902 to fit against the sealing ring 901, thereby forming a secondary seal through the auxiliary sealing part 9. When there is an expansion and contraction gap between the bottle cap 6 and the bottle body 1 due to changes in external temperature, the elastic layer 903 can play an elastic compensation role, thereby compensating for the small gap and further playing the role of preventing leakage.
[0050] Preferably, the sealing ring 901 is fixedly disposed on the arc-shaped wall of the bottle mouth 101, and the cone angle α of its conical surface is preferably 15 to 45 degrees; the material of the sealing ring 901 is the same as that of the bottle body 1, or is an engineering plastic with slightly higher hardness; the material of the contact layer 902 is preferably silicone, rubber or soft thermoplastic elastomer; the elastic layer 903 is fixedly disposed on the bottom inner side of the bottle cap 6, and its material is a compressible elastomer, preferably silicone foam, rubber foam or closed-cell thermoplastic polyurethane (TPU) foam;
[0051] When the bottle cap 6 is screwed onto the bottle mouth 101 via the threaded connection, the contact layer 902 and elastic layer 903 at the bottom of the bottle cap 6 move downwards. The elastic layer 903 is compressed, and the elastic restoring force it generates causes the contact layer 902 to fit tightly against the outer conical surface of the sealing ring 901, thereby forming an additional dynamic sealing barrier between the threaded bottom of the bottle mouth 101 and the threaded sealing gasket 601.
[0052] Specifically, the sealing ring 901 is integrally formed on the arc-shaped wall of the bottle mouth 101; the contact layer 902 is fixed to the elastic layer 903 by bonding or secondary molding process; and the elastic layer 903 is fixed to the bottom of the bottle cap 6 by bonding or secondary molding process.
[0053] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
