Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the utility model and are not to be construed as limiting the utility model.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on those shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element so referred to must have a particular orientation, be constructed in a particular orientation, and be operated, and thus should not be considered as limiting the present invention.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; may be mechanically coupled, may be electrically coupled or may be in communication with each other; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The first embodiment is as follows:

referring to fig. 2, 3 and 4, a health food packaging bottle according to a first embodiment of the health food packaging bottle of the present invention comprises a bottle 1, a bottle cap 2 and a sealing membrane 3, wherein the sealing membrane 3 is disposed on a bottle mouth of the bottle 1, the sealing membrane 3 is heated by electromagnetic induction through a film sealing machine to fuse and seal the sealing membrane 3 with the bottle mouth, the side wall of the bottle cap 2 is provided with internal threads to match with external threads of the bottle mouth, the top surface of the bottle cap 2 is preferably designed to be an outwardly protruding convex surface so as to bear more external pressure on the bottle cap 2, the inner side of the bottle cap 2 is provided with an annular boss 4 protruding toward the bottle mouth, after the bottle cap 2 is screwed on the bottle 1, the annular boss 4 abuts against the sealing membrane 3 to tightly attach the sealing membrane 3 to the bottle mouth, so that the sealing membrane 3 is clamped between the bottle mouth and the annular boss 4 to prevent the sealing membrane 3 from loosening, the sealing effectiveness is ensured, the sealing time can be prolonged, meanwhile, the annular boss 4 can only apply force to the contact part of the sealing diaphragm 3 and the bottle mouth, and avoids a suspension area in the middle of the sealing diaphragm 3, and the annular boss 4 is used for poking the sealing diaphragm 3 open when external force of the bottle cap 2 is prevented.

Generally, the annular projection 4 is provided on the top surface of the inner side of the bottle cap 2, such that the direction in which the annular projection 4 protrudes coincides with the direction of the force applied, the function of the annular boss 4 can be exerted most efficiently, the annular boss 4 extends inwards from the outermost side in the bottle cap 2 in the width direction, the height direction extends towards the direction of the bottle mouth, the contact surface of the annular boss 4 and the sealing membrane 3 is a torus, the torus is consistent with the shape of the bottle mouth, can effectively apply pressure on the sealing membrane 3 corresponding to the bottle mouth, the inner diameter of the circular ring surface is slightly smaller than that of the bottle mouth, the outer diameter of the circular ring surface is slightly larger than that of the bottle mouth, so that the annular boss 4 can completely cover the whole sealing membrane 3 at the contact position with the bottle mouth, of course, the inner diameter and the outer diameter of the ring surface can be made to be consistent with the inner diameter and the outer diameter of the bottle mouth, this makes the assembly more demanding and less reliable than a torus of slightly larger dimensions. The difference between the outer diameter and the inner diameter of the annular surface is preferably 10mm, the size of the annular surface is slightly larger than the thickness of the bottle opening, the position where the sealing diaphragm 3 is contacted with the bottle opening can be completely covered, meanwhile, the influence of assembly errors is also considered, the height of the annular boss 4 protruding out of the inner side of the bottle cap 2 is 2mm, and the normal assembly of the bottle cap 2 and the bottle 1 cannot be influenced on the premise that enough pressure for propping up the sealing diaphragm 3 can be provided.

As shown in fig. 5 and 6, the cross-sectional shape of the annular boss 4 can also be a rectangular or trapezoidal structure, which not only has a stable structure, but also can ensure the overall contact with the sealing membrane 3, thereby achieving the purpose of pressing the sealing membrane 3 and the bottle mouth.

The method comprises the steps of comparing the sealing performance of a packaging bottle adopting the structure of the utility model with that of a common packaging bottle, taking 5 bottles 1 according to YBB00122002-2015 in the method for detecting the sealing performance, filling a proper amount of glass balls into each bottle, tightly covering a bottle cap 2, screwing the bottle and the cap by a force measuring wrench according to 110N cm for a test bottle, placing the test bottle and the cap into a container of a bag air extractor, immersing the test bottle in water, vacuumizing until the vacuum degree is 27kPa, and maintaining for 2 minutes, wherein water inflow or bubbling phenomenon cannot occur in the bottle. The test results are shown in table 1:

serial number	Time to leakage of conventional bottle cap	The bottle cap of the scheme has the air leakage time
			1	115s	150s
2	110s	180s
			3	108s	163s
4	120s	148s
			5	118s	172s
Mean value of	114s	163s

TABLE 1

Through the improvement, the air leakage time of the bottle cap 2 is increased from 114s to 163s, the requirement of 2 minutes is met, and the sealing performance of the product is obviously improved.

Example two:

as shown in fig. 7, the difference from the first embodiment is that the annular boss 4 is arranged at the side position of the bottle cap 2, the cross section is triangular, the sealing membrane 3 can be pressed tightly, and the edge of the sealing membrane 3 and the bottle mouth form a line seal, the structure requires that the sealing membrane 3 extends outwards to protrude out of the bottle mouth, the sealing membrane 3 and the bottle mouth can be pressed into a line seal, and the air tightness of the packaging bottle can be improved.

Other contents not described in this embodiment may refer to embodiment one.
