Screwed can containerTechnical field
The present invention relates to metal Bottle & Can field, be specially a kind of screwed can container.
Background technology
Metal Bottle & Can is drink packing tank common in daily life, and the metal being usually easy to drawing and forming by iron or aluminium etc. is made, and has leak tightness, closing property is good, be convenient to the advantages such as transport.When in tank, encapsulation has as carbonated beverages such as colas, because this beverage is in transportation, the compressed gas cognition be rich in liquid is released, certain pressure is formed thus in the can container closed, when user opens the capping of can container, the compressed gas in the gas of can container and liquid can flash liberation, takes large quantity of fluid out of simultaneously, and then pollute clothing and the contaminated environment of user, bring inconvenience.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of screwed can container that simultaneously can discharge its internal high-pressure gas in the capping of opening can container.
Technical scheme: for solving the problems of the technologies described above, the screwed can container of one of the present invention, comprise cylindrical shape can body portion, the upper opening in can body portion is provided with reducing diameter part, arranges threaded portion above reducing diameter part, the upper opening place of threaded portion forms flanging part, be provided with the bottom that crimping is installed bottom can body, described threaded portion comprises multi-turn ridge, and each circle ridge is provided with the exhausr port of depression, ridge arranges exhausr port, makes each circle form of thread become interrupted tooth line.When opening the bottle cap be connected with threaded portion, the high pressure gas in can container can be discharged rapidly from bottle cap opening direction by in-line arrangement gas port simultaneously, complete pressure release.
Further, the concave face of described exhausr port is arc section.
Further, there is described in the wide l of opening of the exhausr port of arc section1=5 ~ 9mm, with the vertical depth h of crest of screw thread bottom it1=0.3 ~ 0.8mm.
Further, the concave face of described exhausr port is upside-down trapezoid cross section.
Further, there is described in the wide l of upper opening of the exhausr port in upside-down trapezoid cross section2=1.5 ~ 6mm, the width l of bottom3=1.0 ~ 4mm, its degree of depth h2=0.3 ~ 0.8mm.
Further, the transition phase of radius r=2mm is provided with between the upper opening of described exhausr port and ridge.
Further, described each circle ridge is evenly provided with 2 ~ 8 exhausr ports.
Further, the number of active coils of described ridge is 2 ~ 3 circles.
Further, described flanging part is made up of the three-layer coil limit outwards overturn.
Beneficial effect: the screwed can container of one of the present invention, each circle ridge arranges the exhausr port of some, ensure that when opening the bottle cap be connected with threaded portion, high pressure gas in can container can be discharged rapidly from bottle cap opening direction by in-line arrangement gas port simultaneously, completing pressure release, avoiding the high pressure gas when opening formed in can container to go out harm users.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
The screwed can container of one as shown in Figure 1, comprise cylindrical shape can body portion 1, the upper opening in can body portion 1 is connected with reducing diameter part 2, it is the threaded portion 3 of rolling formation above reducing diameter part 2, the upper opening place of threaded portion 3 forms flanging part 4, as shown in Figure 4, flanging part 4 is made up of the three-layer coil limit outwards overturn, bottom 5 for being installed by crimping bottom can body portion 1, threaded portion 3 comprises multi-turn ridge 31, each circle ridge 31 is evenly suppressed with the exhausr port 32 of 2 ~ 8 depressions, the number of active coils of ridge 31 is 2 ~ 3 circles.Ridge 31 arranges exhausr port 32, makes each circle ridge 31 be formed as interrupted tooth line.When opening the bottle cap be connected with threaded portion 3, the high pressure gas in can container can be discharged rapidly from bottle cap opening direction by in-line arrangement gas port 32 simultaneously, complete pressure release.
As shown in Figure 2, as one preferred embodiment, the concave face of exhausr port 32 is designed to arc section, and this has the wide l of opening of the exhausr port 32 of arc section1=5 ~ 9mm, the vertical depth h pushed up with ridge 31 bottom it1=0.3 ~ 0.8mm.
As shown in Figure 3, as another preferred embodiment, the concave face of exhausr port 32 is upside-down trapezoid cross section, and this has the wide l of upper opening of the exhausr port 32 in upside-down trapezoid cross section2=1.5 ~ 6mm, the width l of bottom3=1.0 ~ 4mm, its degree of depth h2=0.3 ~ 0.8mm is the transition phase of radius r=2mm between the upper opening of exhausr port 32 and ridge 31.
Can container of the present invention, during use, coordinates the bottle cap suitable with threaded portion to use simultaneously.
Each circle ridge 31 arranges the exhausr port 32 of some, ensure that when opening the bottle cap be connected with threaded portion 3, high pressure gas in can container can be discharged rapidly from bottle cap opening direction by in-line arrangement gas port 32 simultaneously, completing pressure release, avoiding the high pressure gas when opening formed in can container to go out harm users.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
