Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
Fig. 1 shows a simplified overall structure of the bottle cap proposed by the present application.
The bottle cap can mainly comprise a cap body and a sealing gasket. The sealing gasket is used for sealing the liquid beverage bottle cap.
The bottle cap provided by the application can be a crown cap, a screw cap, a twist-off screw cap (also called an anti-theft cap), a screwing cap (also called a four-screw cap), a press-sealing screwing cap (also called a thermoplastic screw cap), a biting cap (also called a grabbing cap), a side sealing cap (also called a prying cap), a rolling cap (also called a victory bottle cap), an aluminum screw cap, a plastic screw cap and the like. The containers/packages/bottles referred to herein may be vials and jars. The containers/packages referred to herein may be glass bottles, plastic bottles, ceramic bottles, and the like. The glass bottle can be different types of glass bottles manufactured by processing technologies such as manual blowing, mechanical blowing, extrusion forming and the like. The glass bottle can be made of sodium glass, lead glass, borosilicate glass and other glass bottles with different compositions. The ceramic bottle can be a container for packaging white spirit. The plastic bottle can be a disposable or non-disposable plastic packaging container for liquid or solid such as beverage, food, pickles, honey, dried fruits, edible oil, agricultural and veterinary drugs and the like. The crown cap is mainly made of aluminum, is mostly made of tinned foil paper and chromium-plated thin plates, and is mostly used for packaging beer, soft drinks and seasonings. The screw cap is mainly used for packaging solid food in jars, tubular bottles and jars, and is used for packaging wines, fruit juice beverages, seasonings and solid food. The twist-off screw cap (also called anti-theft cap) is used for packing wine. The cap is screwed off (also can be called a four-screw cap), the diameter of the bottle cap is 27-110 mm, the edge of the bottle cap is provided with three, four, six and eight claws respectively, and the bottle cap can be used for packaging juice, jam, fruit, baby food, vegetables, meat and the like in a tubular bottle or a wide-mouth bottle. The press-sealing screw cap (also called a thermoplastic screw cap) is a screw cap with the diameter of 27-77 mm, and can be used for packaging foods such as fruit juice, jam, fruit and the like. The biting cover (also called a grabbing cover) has the diameter of 28-77 mm series and can be used for packaging food such as fruit juice, jam, fruit and the like. The edge sealing cover (also can be called a prying cover) is 27-77 mm in diameter, and can be used for packaging fruit juice, fruits, vegetables and the like. The rolling seal cover (also called victory bottle cover) has good sealing performance and is suitable for packaging fruits, vegetables and meat products.
The cover allows for the manufacture of an indicia coating thereon. The identification coating has an information label with a recognizable pattern, such as a two-dimensional code. The indicia coating may be ink-jet, heat-sensitive/heat-transfer or laser marked onto the cover.
The sealing gasket may be pressed directly into the inner wall of the lid. The sealing gasket may be bonded to the inner wall of the lid by an adhesive. The adhesive can adopt a fully hydrogenated C9 petroleum resin adhesive meeting food hygiene requirements.
The sealing gasket can isolate the identification coating from the package/drink/food in an open-top package/bottle.
The sealing gasket may be an oxygen-consuming structure having a first state and a second state. When the bottle cap is not used, that is, the bottle cap is not covered on the bottle body, the sealing gasket is in a first state. When the bottle cap is used, that is, the bottle cap is already covered on the bottle body, the bottle body is relatively closed, or the bottle cap is unscrewed when the bottle cap is used by a consumer after leaving a factory, and at the moment, the sealing gasket is in a second state. The sealing gasket in the second state is under the action of pressure and is in an elastic compression state. The sealing gasket in the first state is in the external environment and does not contact the beverage in the bottle; the sealing gasket in the second state is in a relatively closed environment and at least contacts the beverage in the bottle. The identification coating on the cover can be observed through the sealing gasket in the first state or the second state, namely, the sealing gasket can keep better relative transparency in the first state and the second state.
The sealing gasket may be provided at least in part with a layer of oxygen-consuming material and/or a transparent viewing area. Aiming at the position where the two-dimensional code is arranged on the cover body, the sealing gasket is provided with an oxygen consumption material layer (or called transparent visual area) at the opposite position. The oxygen consumption material layer is not arranged at the position corresponding to the two-dimension code, but at least comprises the oxygen consumption material layer which is not discolored after oxygen absorption and is arranged at the position corresponding to the two-dimension code. That is, an oxygen-consuming material layer that does not change color after oxygen inhalation, an oxygen-consuming material layer that changes color after oxygen inhalation, or both may be provided at a position corresponding to the two-dimensional code.
As shown in fig. 2, the gasket seal may include a first resilient layer and a second resilient layer. The first elastic layer and the second elastic layer are bonded to each other in a non-flat manner, that is, the bonding surface can be a sawtooth surface or a curved surface or other non-flat surfaces.
The first and second elastic layers may each comprise polyethylene of different degrees of polymerization. The elastic layer may further include copolymers of alpha-olefins such as ethylene, propylene, 1-butene, 1-pentene, 1-hexene, 1-octene, 4-methyl-1-pentene, and cyclic olefins. The elastic layer may also include one or more of mineral oil, liquid rubber, vegetable oil, food grade white oil, food grade paraffinic oil, naphthenic oil.
The first elastic layer may be provided with an oxygen-consuming material layer on the inside. The second elastic layer may be provided with an oxygen impermeable material layer on the inside. The layer of oxygen-consuming material and/or the layer of oxygen-impermeable material may be a corrugated structure.
The oxygen-consuming material layer may be an inorganic oxygen-absorbing material. The inorganic oxygen absorbing material may include one or more of iron-based oxygen scavenging material, polyol salt, metal salt, catechol. The iron-based oxygen scavenging material may include one or more of iron powder and ferrous oxide. The metal salt may comprise one or more of potassium persulfate, potassium hydrogen persulfate, sodium persulfate, and sodium hydrogen persulfate. The oxygen-impermeable material layer may adopt a double-layer composite film structure coated with PVDC (polyvinylidene chloride), such as KPET (coated polyester film) and CPP (cast polypropylene film). A two-layer composite film structure may include a primary stress layer/barrier layer/heat seal layer/peelable layer. The primary stressed layer may be PS (polystyrene), HIPS (high impact polystyrene), PP (polypropylene), PET (polyethylene terephthalate), etc. The barrier layer may be EVOH (a random copolymer of ethylene vinyl alcohol), PA (polyamide), PVDC (polyvinylidene chloride), or the like. The heat sealing layer can be HDPE (high density polyethylene), LDPE (low density polyethylene), LLDPE (linear low density polyethylene), CPP (casting polypropylene film) and the like; the peelable layer is PP (polypropylene) or the like.
