Background
At present, plastic bottle caps for food, beverage and medicine are manufactured by adopting an injection molding cap manufacturing technology in most food and medicine industries. Particularly, in the pharmaceutical packaging industry, the detection requirement of the national food and drug administration on a heat-seal gasket bottle for pharmaceutical packaging is that the heat-seal gasket bottle does not leak gas within 3 minutes under the condition that the vacuum degree is negative 27kpa under the condition that the heat-seal gasket is not contained, and the detection requirement is difficult to achieve after the existing packaging bottle and bottle cap are matched. On the other hand, when the medicine is packaged and delivered from a factory, the bottle mouth needs to be subjected to aluminum foil heat sealing, but the existing bottle cap is frequently subjected to sealing leakage in the heat sealing process, so that the qualified rate of sealed products is low.
Disclosure of Invention
To the weak point among the above-mentioned prior art, the utility model provides a bottle lid that the leakproofness is good increases pressure ring structure and bulge loop on its bottle lid, improves the sealed effect under the no heat seal aluminium foil condition to and the poor problem of heat seal effect among the prior art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a bottle lid that leakproofness is good, includes the bottle lid body, have on the inside wall of bottle lid body with bottleneck external screw-thread fit's internal thread, its characterized in that: the bottle cap comprises a bottle cap body and is characterized in that the inner top surface of the bottle cap body is provided with a plurality of compression rings which are coaxial with the bottle cap body, and when the bottle cap body is matched with a bottle opening, the compression rings are arranged coaxially, the compression rings are arranged just opposite to the opening edge of the bottle opening in a plurality of ways, and the distance between the compression ring on the outermost side and the compression ring on the innermost side is smaller than the width of the opening edge of the bottle opening.
Furthermore, the number of clamping rings is two, in top surface arranges with one heart in the bottle lid body, and two the height and the width homoenergetic of clamping ring are equal.
Furthermore, the outer side wall of the bottle cap body is provided with anti-slip lines.
Further, the anti-skid lines are reticulate lines or vertical lines.
Further, the longitudinal section of the pressing ring is an inverted triangle or trapezoid.
Further, the height of the compression ring is 0.2-0.3 mm.
Further, the internal thread is an inclined thread, the included angle between the upper side surface of the internal thread and the inner side wall of the bottle cap body in the vertical plane is 121 degrees, and the included angle between the lower side surface of the internal thread and the inner side wall of the bottle cap body in the vertical plane is 146 degrees.
Furthermore, a convex ring is further arranged on the inner side wall of the bottle cap body and located between the internal thread and the inner top surface of the bottle cap body, an annular groove is formed between the convex ring and the inner top surface of the bottle cap body, and a heat-seal gasket is arranged in the annular groove.
Further, the convex ring is a semicircular ring protruding towards the inner side of the bottle cap body.
The beneficial effects of the utility model include: the sealing effect that bottle lid and bottle are better under can satisfying not having heat-seal gasket, and the heat-seal gasket is compressed in advance to the clamping ring when the heat-seal, can make the heat-seal of heat-seal gasket effectual, the phenomenon that can not appear leaking and seal, and the heat-seal gasket is difficult for dropping in the bottle lid.

Detailed Description
The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
Referring to fig. 1-4, the preferred embodiment of the present invention includes a bottle cap body 1, an internal thread 3 matching with the external thread of the neck of the bottle 7 is provided on the inner sidewall of the bottle cap body 1, a protruding ring 4 is further provided on the inner sidewall of the bottle cap body 1, the protruding ring 4 is located between the internal thread 3 and the inner top surface of the bottle cap body 1, and an annular groove is formed between the protruding ring 4 and the inner top surface of the bottle cap body 1. The width of an annular groove formed between the convex ring 4 and the inner top surface of the bottle cap body 1 is 1.2-1.5 mm. This ring channel is used for holding heat-seal gasket 6, can be so that heat-seal gasket 6 is difficult for dropping from bottle lid body 1, and on the other hand the internal diameter of bulge loop 4 slightly is less than the diameter of heat-seal gasket 6, just bulge loop 4 to the protruding semicircle ring of bottle lid body 1 inboard for can not take place to curl when packing into bottle lid body 1 with heat-seal gasket 6, thereby influence the heat-seal effect.
The bottle cap is characterized in that the inner top surface of the bottle cap body 1 is provided with press rings 5 which are coaxial with the bottle cap body 1, the number of the press rings 5 is one or two or three, and the two press rings 5 are optimal. Two 5 coaxial the arranging of clamping ring, work as when bottle lid body 1 and bottleneck cooperation, two clamping ring 5 just to the mouth edge of bottleneck, and two the interval of clamping ring 5 is less than the width on bottleneck mouth edge. The longitudinal section of the compression ring 5 is an inverted triangle or trapezoid, and the trapezoid is preferred in the embodiment. The height of the trapezoidal compression ring is 0.2-0.3 mm. The compression rings 5 have the effects that on one hand, the compression rings 5 compress the heat-seal gasket 6 on the bottle mouth in advance during heat sealing, so that the heat-seal gasket 6 is well contacted with the bottle mouth during heat sealing, the existing sealing leakage position is avoided, the two concentric compression rings 5 can ensure that when one compression ring has an injection molding gap, the other compression ring can play a role in compressing, and the compression effect is ensured by redistribution; on the other hand, when the heat-seal gasket 6 is not arranged, the press ring 5 is directly contacted with the opening edge of the bottle opening, so that the effect of a seal ring is formed, the negative pressure detection requirement under the condition that the heat-seal gasket 6 is not contained is met, namely, the air leakage phenomenon does not occur within 3 minutes under the condition that the vacuum degree is negative 27kpa, and the detection requirement of the national food and drug supervision administration on drug packaging is met.
In order to facilitate the opening or tightening of the bottle cap body 1 with respect to the bottle body 7, the outer side wall of the bottle cap body 1 is provided with anti-slip threads 2. The anti-skid grains 2 are reticulate patterns or vertical stripes, in this embodiment, vertical stripes protruding outwards are preferred, and the cross section of the stripes is triangular.
In order to further improve the sealing performance between the bottle cap body 1 and the bottle body 7, preferably, the internal thread 3 is an inclined thread, the included angle between the upper side surface of the inclined thread and the inner side wall of the bottle cap body 1 in the vertical plane is 121 degrees, the included angle between the lower side surface of the inclined thread and the inner side wall of the bottle cap body 1 in the vertical plane is 146 degrees, the bottle body 7 is provided with an external thread corresponding to the internal thread on the bottle cap body 1, and the inclination angle of the thread is complementary to the internal thread.
The technical solutions provided by the embodiments of the present invention are described in detail above, and the principles and embodiments of the present invention are explained herein by using specific examples, and the descriptions of the above embodiments are only applicable to help understand the principles of the embodiments of the present invention; meanwhile, for a person skilled in the art, according to the embodiments of the present invention, there may be variations in the specific implementation manners and application ranges, and in summary, the content of the description should not be construed as a limitation to the present invention.
