Table 1

For the consumption of moving about of flowable product, especially edible food product, packaging scheme generally includes has the container that distributes mouth, and this distribution mouth can utilize closure elements (for example nut) again to seal.This packing is widely known by the people, and it allows customer to carry out dispense contents with good flow.

Yet, in order to ensure failure-free, distributing and good flow, container makes: when distributing mouth not seal, if if container lean or under normal conditions content start to contact with distributing mouth, content can overflow.In this case, content is directly through distributing mouth to flow out.

In order to overcome this defect, developed so-called " sports type closure member ", it comprises distribution passage, by the closure elements that promotes conventionally can not disassemble from the remainder of closure member, can easily seal described distribution passage.This sports type closure member is widely known by the people, and has proposed different systems, for example, and push-pull closure member, hinge type closure member etc.Therefore yet these closure members manufacture complexity and costliness, the price of product is higher for consumers, especially in the situation that container for thering is the consumption of moving about of the product of limited content volume.In addition, these closure members need to be for their lot of materials of different component parts.In addition, a main defect is that this sports type cap can not leak when customer seals them.

Due to the defect of sports type closure member, developed the closure member of other type, it comprises elastomer valve, as slit valve.This valve closure member is failure-free, their uses in packaging for foodstuff industry---for example, for packing honey, catsup etc.---increased.A very important advantage is that this closure member needn't require the top cover in order to seal valve adding.In other words, valve self has enough elasticity with sealing again after distributing, even if make when container lean, the content contacting with the inside face of valve can not leak yet.This explains aobvious to customer be useful.

Yet, this slit valve is manufactured expensive, because they relate to the multiple material for closure member: closure body is made by polyethylene or polypropylene conventionally, slit valve self is made by silicone resin or other similar elastomeric material, and this slit valve must fit together with closure body or be injection molded altogether with closure body.

The container of known other type, it is the single-piece flask making by the extrusioning-blow such as poly thermoplastic plastic.This container comprises container body, and this body manufactures one together with removable tip.When tip is torn it down by user, in wall of container, form the minimum dispense aperture that allows dispense contents.This container is widely used in pharmaceutical industry, for single dose (single doses) is provided, for for example carrying out topical therapeutic by lotion (that is, auristilla or eye drops).The advantage that this lotion list doses container has is, although content be liquid or be at least highly susceptible to mobile product and also can not leak through dispense aperture, even if described content contacts with the inside face of dispense aperture.Yet, these containers have obvious shortcoming,, due to their manufacturing process and structure, they are only applicable to very little content volume---be conventionally less than 5ml, this obviously with food service industry for example in consumer products incompatible, in food service industry, need to have over 10ml, preferably surpass the container of the content of 50ml.

Therefore, existence (that is, conventionally surpasses 10ml, preferably surpasses 50ml having the content volume compatible with the consumption of the fluid goods for consumption of for example edible food product, more preferably surpass 25cl) the demand of larger container, wherein said container low cost of manufacture.

Importantly, this container should allow enough flows in assigning process, but simultaneously described container should prevent the leakage of content, even when dispense aperture is not closed system lock and container lean and makes the interior side contacts of content and dispense aperture.
