Abstract

A directly-pushed type bottle cap consists of a cover body [4] and a seal sheet [1]. The utility model is characterized in that the top of the cover body [4] is concavely equipped with an inserting guide port [7], the bottom of the inserting guide port is equipped with a bottom cover [5]. The bottom cover [5] and the bottom of the inserting guide port [7] is a one-body injection molding connection structure, wherein, the wall thickness of the ring-shape borderline ring forming along the edge of bottom cover [5] is the thinnest size within the scope of the inserting guide port [7]. The proposal designs the bottom of the guide port of the bottle cap to a bottom cover structure completed by the one-body injection molding, so the sealing problem of the bottle cap is better solved. Meanwhile, the structure of the edge of the bottom cover is designed to the structure of ring-shape fracture ring with the thinnest wall thickness at local part, when the bottom cover of the bottle cap acts on the water diversion mouth of water drinking machine, the bottom cover easily fractures along the fracture ring and can finally be pushed to open, so that the pure water in the bucket flows into the water drinking machine. The utility model changes the original bottle cap of three components to bottle cap of two components, not only simplifies the structure and saves the raw materials, but also makes the structure more practical, and especially has obvious effect on mass production of bottle cap.

Description

The straight top type bottle cap

Technical field

The utility model relates to a kind of Bottle cap structure, particularly a kind of Bottle cap structure that uses on the system of the moulding GPB of can pure water that is exclusively used in.

Background technology

The can pure water is very universal as the potable water of people's daily life and work, for the water quality that guarantees pure water also very strict to the requirement of the GPB of splendid attire pure water and bottle cap.Usually use a kind of movable plug-in Bottle cap structure on the system of the moulding GPB of can pure water at present, see accompanying drawing 4, this bottle cap is made up of lid 4, clever mouth 10 and mounting 1 three members, lid 4 central authorities are provided with one section through hole, clever mouth 10 plugs are in the bottom of through hole, mounting 1 is snapped in the draw-in groove 3 on through hole top by its set snap ring 2 in bottom, plays the effect of sealing bottle cap mouth.During assembling, clever mouth is upwards filled in the through hole from the lower end of lid through hole, after waiting to fill pure water, lid is enclosed within the neck of GPB, and then with on the mounting cap seal.When the user uses, throw off mounting from the mouth that pulls out at lid top earlier, then GPB is inverted, and the diversion mouth of bottle cap inlet aligning water dispenser is firmly inserted, diversion this moment mouth backs down clever mouth, makes the interior pure water of bucket enter water dispenser.Although above-mentioned Bottle cap structure has become the main flow of can pure water bottle cap, on market, has certain representativeness, but this bottle cap also exposes many deficiencies in the practice: 1, owing to adopt clever mouth to stop up the bottle cap mouth of a river, poor sealing, particularly summer temperature is higher, drainage takes place in plastics deliquescing easily; 2, clever mouth is in plug inefficacys that the time come off easily, and floats over after coming off on the water surface in the bucket, causes bad sensation to the drinking-water person; 3, because the GPB that is filled with water is heavier, the unclever at that time mouth of dress water inclination angle has been scraped the material silk at hole wall and has been fallen into the water, and stops up apopore sometimes; 4, have fine clearance between the clever mouth and the mouth of a river, this gap is easy to residual disinfectancy liquid is carried in the pure water.For this reason, the utility model is from improving the angle of structure, designed a kind ofly can satisfy the bottle cap operating needs, and can GPB straight top type bottle cap simple in structure, and to overcome above deficiency, simplified structure simultaneously.

Summary of the invention

For achieving the above object, the technical solution adopted in the utility model is: a kind of straight top type bottle cap, form by lid and mounting, the top of lid is concaved with the insertion guiding port, its bottom of inserting guiding port is provided with a bottom, bottom is an one injection moulding connection structure with inserting the guiding port bottom side, and the wall thickness that the annular boundary that wherein forms along the bottom edge is enclosed on the path is the thinnest in inserting the guiding port scope.

In the technique scheme, described " lid " is meant the bottle cap body structure.Described " mounting " is meant that the sealing bottle cap inserts the cover plate of guiding port, also claims theft protection plate.Described " insertion guiding port " is that the guiding that the diversion mouth docks with bottle cap when pointing to the GPB of water dispenser can band pure water enters the mouth.

In the technique scheme,, the thick annular of the thin-walled circle path that has a common boundary should be set structurally along the bottom edge in order to make easier being backed down of bottom on the straight top type bottle cap.This structure can comprise following several situation:

1, be provided with reinforced rib on bottom, reinforced rib extends to the bottom edge.Described reinforced rib can single face setting on bottom, also can two-sided setting on bottom.

2, be provided with ring channel structures in bottom edge.Described circular groove can be in the single face setting of bottom, also can be in the two-sided setting of bottom.

3, the one side at bottom is provided with reinforced rib, and another side edge is provided with ring channel structures.

The utility model principle of work is: bottle cap guiding port bottom design is become the bottom cover structure of finishing by the one injection moulding, preferably resolve the sealing problem of bottle cap like this, simultaneously, structurally the bottom edge designs is become local wall thickness final thin circumferential separation coil structures, the bottom ratio is easier to break along the fracture circle when the bottom of bottle cap acts on the diversion mouth of water dispenser, finally backed down, make the pure water in the bucket enter water dispenser.

Because the technique scheme utilization, the utility model compared with prior art has following advantage:

1, because the utility model becomes the bottom cover structure of finishing by the one injection moulding with bottle cap guiding port bottom design, the good airproof performance of obvious bottle cap, the not phenomenon that can leak again.

2, the utility model has become the bottle cap of original 3 member designs into 2 member designs, not only simplifies the structure, and has saved a member, and has saved raw MAT'L, especially has effect significantly to producing bottle cap in enormous quantities.

3, the whole obscission of bottom can not take place in the utility model straight top type Bottle cap structure when the diversion mouth backs down bottom, is just backed down to bottom to a certain degree because bottom breaks along the fracture circle, and bottom always had one section and still was not connected with guiding port and can comes off this moment.Therefore original clever mouth can not take place float on the interior water surface of bucket, cause bad sensation for the drinking-water person.

4, the utility model becomes local wall thickness final thin circumferential separation coil structures with the bottom edge designs, and bottom is opened easily during use, and is firmly little, and is little to the wearing and tearing of the diversion mouth of water dispenser, and the impact at water dispenser top is also reduced.In addition, effectively avoided clever mouth inclination angle to hole wall scraping phenomenon.

5, do not have fine clearance in the utility model structure, the residue of thimerosal can be carried in the pure water, make pure water remain original quality.
