Abstract

The utility model discloses a turnbuckle sealing container which comprises a container cover and a container body. Outer threads are arranged at the upper end of the container body and are multiple threads. A screwing stopping groove is formed at the bottom of the threads and is larger than the threads in depth. According to the turnbuckle sealing container, the screwing stopping groove is used to be combined with the multiple threads, so that the sealing performance of a wide-mouth container can be effectively improved; the screwing stopping groove and the threads are different in depth so as to be capable of enabling the container to form self-locking after being screwed and improve the fastening performance of the container. Moreover, the multiple threads are adopted, so that the container cover can be opened and closed conveniently.

Description

The turnbuckle airtight container

Technical field

The utility model relates to a kind of packing container, relates in particular to a kind of good seal performance, can prevent the turnbuckle airtight container of leaked liquid.

Background technology

For the multi-form packing container that has of article packings, and in order to prevent that article from dropping, or anti-sealing, air etc. enter in container, and most containers can adopt lid that interior of the container is closed.Container cover has multiple different connection fastening means from container, as utilizes buckle to connect, adopts that screw top is threaded etc., and its kind comprises crown cap, screw top, only revolves screw top, easy-open end etc.

It is little that the mode of screw top sealing is generally used for the opening such as water bottle, and on the higher container of body height, this mode leak tightness is stronger, can effectively prevent the leakage of liquid in containers; And the usage comparison that buckle connects is extensive, multiplex on the larger packing container of opening, be characterized in opening and cover easily, easy to use, however its leak tightness is poor, is not suitable for being used on the container package of contain fluid.

Large for opening, the container that the outer wall height is low, the mode that adopts screw top to seal is also arranged, yet because this class sidewall height is low, on container cover and container outer wall, establish threaded length little, and nominal diameter is excessive, add the container nominal diameter large, adopt the mode of single screw thread to need lead angle little, otherwise, only some is wound with helix line for container cover and container outer wall, difficulty of processing is large like this, lead angle is little simultaneously, its pitch is overstocked, can affect the intensity of wall of container, therefore for this class container, should adopt many screw threads, but its leak tightness of the mode of many screw threads and fastening poor performance, can't be applicable to the container of contain fluid.

The utility model content

Technical problem to be solved in the utility model is, a kind of turnbuckle airtight container is provided, and comprises container cover and vessel, there is outside thread described vessel outer wall upper end, described outside thread is multiple-screw thread, and the described bottom of thread has only spin slot, and the described only degree of depth of spin slot is greater than depth of thread.

Further, arc projection between described only spin slot and described outside thread, slide into described outside thread be used to preventing the container cover projection easily from described only spin slot, avoids unclamping of container cover, strengthens steadiness.

Further, along inboard, be provided with the projection corresponding with described outside thread position under described container cover, described projection cross section is along the opening and closing of container cover of having slided of vessel outside thread.

Further, described container cover projection internal diameter is less than described vessel root diameter, described container cover projection internal diameter is greater than described only spin slot internal diameter, when described projection is positioned at the position of screw thread, slight deformation occurs in the container cover projection, make described container cover and described vessel be not easy to become flexible, described projection restores to the original state when described projection slides into described only spin slot, and container cover and vessel seal fully.

Further, described outside thread tooth form is rectangle.

Implement the utility model, have following beneficial effect:

The utility model utilization stops spin slot and multiple-screw thread combines, can effectively increase the leak tightness of large container, only spin slot can make containers different from depth of thread screw rear formation self-locking, improve its fastening performance, and adopted the mode of multiple-screw thread, facilitated opening and closing of container cover.

The accompanying drawing explanation

Fig. 1 is the structural representation of the utility model vessel;

Fig. 2 is the utility model container cover example structural representation.

The specific embodiment

For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is described in further detail.

Vessel 1 as shown in Figure 1, there is outside thread 11 described vessel 1 outer wall upper end, and described outside thread 11 is multiple-screw thread, and the described bottom of thread has only spin slot 12, and the described only degree of depth of spin slot 12 is greater than depth of thread 11.

In the present embodiment, the described number of leads is six lines.

Preferably, arc projection 13 between described only spin slot 12 and described outside thread 11, slide into described outside thread be used to preventing the container cover projection easily from described only spin slot, avoids unclamping of container cover, strengthens steadiness.

Preferably, described outside thread tooth form is rectangle.

Fig. 2 is the structural representation of container cover, and described container cover 2 times is provided with the projection 21 corresponding with described outside thread position along inboard, and described projection cross section is along the opening and closing of container cover of having slided of vessel outside thread.

Further, the internal diameter of described container cover projection 21 is less than described vessel root diameter, described container cover projection 21 internal diameters are greater than described only spin slot internal diameter, when described projection 21 is positioned at described externally threaded position, slight deformation occurs in described container cover projection 21, make described container cover and described vessel be not easy to become flexible, described projection 21 restores to the original state when described projection 21 slides into described only spin slot, and container cover and vessel seal fully.

In the present embodiment, the quantity of described projection 21 is 6.

Above disclosed is only a kind of preferred embodiment of the utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belong to the scope that the utility model is contained.

Claims
