Description

Food packaging canister

Technical field

The utility model belongs to the technical field of food container more particularly to a kind of food packaging canister.

Background technology

For many people when social activity, tea are poly-, custom can make tea leaf for friend's trial test on than the one or two of higher gears.It is more preceding Year, these tealeaves are incorporated into greatly inside plastic-aluminum combined film pouch, but are that tealeaves is taken with oneself the shortcomings that plastic-aluminum combined bag film It is broken or even crowded rotten that extrusion is easily squeezed during band, does not meet the requirement of high-grade tealeaves.Then, people are just with using rigid material The packing jar of making packs high-grade tealeaves.It makes tea leaf since the volume of these packing jars is typically only used for about containing one, because And it is also known as " canister ".Every time behind Kaifeng, the tealeaves in canister generally can be poured out all, thus its design feature and structural requirement Different from traditional big tank（Tealeaves after traditional big tank breaks a seal every time in tank need to only take sub-fraction）.

On the material selection of packaging canister, the possible option of one of which is to select metal material, but metal material Packing jar has the following disadvantages：, there is the security risk for injuring hand in the first, cover tearing procedure or after tearing；2nd, metal material Packing jar appearance it is often not thick and heavy enough, slightly seem frivolous.Above-mentioned two feature does not meet high-grade tealeaves, high-grade society equally yet The requirement in place is handed over, then people just start to make food packaging canister using plastic material.

But the tea packaging canister that existing plastic material makes still has following deficiency：First, in sealing performance and unlatching There are dilemmas in terms of comfort level：If good seal performance, mean that engaging is close and it is difficult to cause to open, conversely, If it is easy to open, mean poor sealing performance, and the easy moisture absorption of tealeaves is made moist, high-grade tealeaves becomes once moisture absorption is made moist It is low-grade；2nd, due to comparison of brands top grade, some illegal businessmans can recycle the tea packaging canister of existing plastic material making Packaging canister was used, the tealeaves of personation of poor quality then is put into packaging canister carries out personation sale, therefore compromises factory of an established trade mark The reputation prestige of family, sales volume.

Utility model content

A kind of food packaging canister, its sealing performance are provided the purpose of the utility model is to overcome disadvantages mentioned above Good, it is easy to open, and other businessmans can not be tipped the customers using secondary package is carried out after opening.

Its purpose can be realized by following scheme：A kind of food packaging canister, the circular tank formed including plastic production With interior cover, outer cover, interior cover lid is closed on circular tank, and outer cover includes outer capping, outer cover rim, the outer cover of outer cover Edge is formed with internal thread；The tank mouth edge position of circular tank is formed with external screw thread, and both outer cover and circular tank utilize spiral shell Line is screwed together；It is characterized in that：Inner canister is covered with interior capping, inside and outside two layers edge, wherein the interior cover lid positioned at internal layer Along referred to as internal layer cover rim, and the interior cover cover rim positioned at outer layer is known as time outer cover edge, secondary outer cover edge, internal layer cover rim, inner cover Face three in one is molded, and the top on internal layer cover rim and time outer cover edge connects together and is formed with annular clip slot, marmon clamp Downward, interior capping is equipped with tear trace line, interior capping also one to the notch of slot with the circular boundary line of internal layer cover rim between the two Body is connected with knob ring；The tank mouth edge position of circular tank is due also to outer diameter changes and is formed with bank rank outside annular；Positioned at ring Tank mouth edge position above the outer bank rank of shape is known as tank mouth epimere, is known as tank positioned at the tank mouth edge position outside annular below bank rank Mouth hypomere, the outer diameter of tank mouth hypomere are equal to the outer diameter on time outer cover edge, and the outer diameter of tank mouth epimere is equal to the internal diameter on time outer cover edge, The height of tank mouth epimere is equal to the depth of annular clip slot, and the thickness of tank mouth epimere is equal to the vallecular cavity width of annular clip slot, in tank mouth Section tight fit is embedded in the annular clip slot of interior cover；The external screw thread of the circular tank is formed at tank mouth hypomere.

The annular convex edge that the bottom of the internal layer cover rim is protruded along oriented centrifugal direction is formed, the tank mouth side of the circular tank Along position bank rank in annular is formed in inner peripheral surface since internal diameter changes；The annular convex edge of internal layer cover rim is tightly stuck in circle In the annular of shape tank body below bank rank.

So-called centrifugal direction, the i.e. direction away from circular tank central axis.

The utility model has the following advantages and effect：

First, the utility model uses the cover of inside and outside bilayer, and outer tank is covered with outer cover rim, and inner canister is covered with inside and outside Double layer lid Edge, annular clip slot and the tank mouth position of interior cover are fitted close, thus are formed with the moisture-proof damp proof defence line of multiple tracks, in interior cover quilt Before unlatching, good seal performance, especially suitable for packaging tealeaves.

2nd, the utility model is using knob ring and the easy open cover mode of tear trace line cooperation so that the opening square of packing jar Just, as long as tear trace line is torn, and due to being plastic material, thus interior capping tear after there is no scratch finger It is dangerous.

3rd, in the utility model opening process, since tank mouth epimere tight fit is embedded in the annular clip slot of interior cover, and And the annular convex edge of internal layer cover rim is tightly stuck in the annular of circular tank bank rank in the following, clamping force substantially exceeds tearing mark The tensile capacity of line, therefore once pull open knob ring, tear trace line will be firstly broken tear, in this way, illegal businessman is just again Also secondary package tealeaves of poor quality can not be carried out using the packing jar, is conducive to safeguard the reputation and interests of producer of an established trade mark.

4th, the tank body plastic simplicity of the utility model, it is high-grade generous.
