Abstract
The utility model discloses a sealing container with internal and external threads. The structure is characterized in that an internal thread and an external thread are arranged on a neck port of a container. An external thread and an internal thread which are matched with the neck port of the container are arranged on a cover of the container. A sealing ring is arranged on the bottom of an internal thread and the bottom of an external thread of the cover of the container. The utility model has the advantages that liquid can not easily flow out or volatilize form a port of the container, because a container containing liquid is provided with multi-layer barrier of the internal thread, the external thread, and the sealing ring in the course of transportation, and also has the advantages of good sealing effect, convenient transportation, easy manufacture, and convenient operation. The utility model is especially suitable for various containers which are used for packaging liquid.
Description
The utility model relates to the container that is used for object or storing material or transportation, relates in particular to be configured in the mouth piece of eck.
The domestic and international now container that seals with screw thread, because of container orifice has only outside thread or negative thread, sealing place is big with the liquid in container contact surface, liquid is easy to rise to smoothly eck,, outwards outflow downward from thread gaps, perhaps from the volatilization of eck slit, sealing effectiveness is bad.Henan soy sauce factory exports 100,000 barrels of soy sauce recently, transports seriously leakage after the U.S. to, brings about great losses, and appeals that domestic urgent need solves the standard export packages problem.
The purpose of this utility model provides a kind of good airproof performance, is convenient to transport, make airtight container simple, easy to use.
The technical solution of the utility model is, is provided with negative thread and outside thread on the eck of vessel, and container cover is provided with outer, the negative thread that matches with the body eck, is that a seal ring is put in the internal and external screw thread portion bottom of container cover at the container neck top.For sealing better, tighten container cover, seal ring sticks with glue in the container cover bottom.
The internal and external screw thread of said vesse body and container cover is that square thread or saw thread effect are best.
Vessel and container cover can be used plastic production.
Owing to take technique scheme, in transportation, when container was subjected to external force and shakes, the liquid in the container was difficult for rising to the neck top and outflows, in the container that falls back naturally because of being subjected to the multilayer barrier of internal and external screw thread and seal ring; The double-deck screw thread of container cover has been offset the influence of het expansion, and when container cover is collided, outer if any the crack, internal layer also can play sealing function.The use of double-deck screw thread simultaneously can make the thickness of seal ring increase, and has strengthened sealing effectiveness.In long-distance transport, as seal ring is fixed in the neck top with glue, because of having glue to shut in the crack in covering, sealing effectiveness is better.In addition, the utility model design of part is simple, low cost of manufacture, easy to use, is applicable to various packing containers and bottle.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Fig. 1 is the structural representation of the utility model internal and external threads airtight container.
Fig. 2 is the structural representation that the utlity model has upper and lower covers.
In Fig. 1, container cover body 1 and container cover 2 are used plastic production, and outside thread is connected with screw-internal thread fit on the negative thread 4 of container body eck, outside thread 5 and the container cover, at the eck top seal ring 3 is housed, and is stained with glue 2 in the slit.
Fig. 2 is a kind of double-canopy barrel of cement, and the upper end of barrel of cement 6 is provided with negative thread 4, outside thread 5, seal ring 3, and the barrel of cement lower end is provided with negative thread 8, outside thread 9 and seal ring 10.
