The feeding lid of the container of splendid attire free-flowing material

Technical field

The present invention relates to a kind of feeding lid of using for the container, particularly drinking container of splendid attire free-flowing material.

Background technology

Many kinds of project organizations of existing this feeding lid in the prior art, this container cover are used for the drinking container made by various materials especially glass and plastics.

Particularly in recent years, the drinking container of this pattern and feeding lid are used to various uses, thereby its demand constantly increases.To this feeding lid, on the one hand, even require it that the failure-free leak tightness is also arranged when container inner pressure is very high, when for example in motion process, carrying drinking container, its inside will produce high pressure, on the other hand, wishes that it allows the user optionally to take wherein material, particularly can arbitrarily drink beverage wherein, general and this feeding lid of user's mouth direct contact when drinking.

Summary of the invention

So, the objective of the invention is provides a kind of improved feeding lid for the container of splendid attire free-flowing material, especially for above-mentioned drinking container, this container cover, can guarantee improved sealing on the one hand, can allow the user that a kind of comfortable sensation is arranged when covering with this feeding of outspoken contact on the other hand.

This purpose of the present invention will be covered with a kind of feeding of the container that is used for the splendid attire free-flowing material, especially drinking container and reach.This feeding lid comprises: the lid that upper cover part is arranged, extend tubular portion downwards from the outward flange of upper cover part, and this tubular portion can be fastened on the vessel port part of container; Outlet on end face that is positioned at lid, this outlet is communicated in the vessel port of container; And, a buckle closure that is used to open and close the outlet of described lid, the arch teat of lid divides the described outlet round lid, lid is provided with one and covers jacket on the outside face that described arch teat divides, material and/or the material of upper cover part and/or the material softer of lid that the material of this jacket divides than described arch teat at least in part.

This feeding lid of the present invention for example has as snug as a bug in a rug contiguous sense can for the user in drinking process, because user's contact is by the jacket of making than soft material.And, be by closing outlet owing to be used to seal the buckle closure of outlet, and jacket is used than soft material and is made, so the sealing of this feeding lid has improved greatly with the direct contact of jacket.Also have, owing to have very high compressibility than soft material, like this, the size of jacket needn't too accurately just can reach the failure-free sealing, therefore needn't make the franchise precision to it and propose too high requirement.The anti-error opening apparatus (tamperproofing means) of a mouth piece form if necessary, can also be set for the outlet of lid.Use this structure, before container was opened first, air or oxygen can not enter internal tank, and this just can keep the quality of the material in the container.This anti-error mouth piece of opening can be a same material with jacket and/or lid.In addition, guarantee material high-quality in the container in this way, can simplify the production process of this feeding lid greatly and reduce the batch manufacturing cost.So the present invention is based on a surprising discovery, the jacket that promptly is provided with than soft material can address the above problem, and can achieve the above object in other words conj.or perhaps.

Another advantage that is provided with than this feeding lid of the jacket of soft material is not produce noise in its opening and closing process, this be because its buckle closure particularly joint bonded assembly buckle closure when opening and closing, do not have disrumpent feelings noise.Particularly, if in the environment that needs are kept quite, for example do not produce noise when opening and closing in the library or in lecture is carried out have the container of this container cover, this is an advantage.

Various thermoplastic polymeric materials, particularly thermoplastic polyester (TPE), high pressure polymerisation thing (low density polyethylene) are the preferred materials of making jacket, but also can be with other nonrigid plastic, rubber and/or silica gel.These materials can be adjusted to needed jacket soft or hard degree, also will make the soft or hard degree of formation enough stable, to guarantee the long-term use life-span of jacket thereby this feeding lid.

Certainly, jacket also can be made by two or more mixtures of material in the above-mentioned material, and this also belongs within the scope of the present invention.

Preferably, lid and be made for one to the arch teat branch of the fair head of suction upper process and that can be used as drinking person from the top edge of lid.And preferably, the diameter that the arch teat divides is stair-stepping in its short transverse, and the upper end diameter that the arch teat divides is less and be provided with described outlet.

In a preferred embodiment, jacket is designed to cover the outer surface that the arch teat divides basically fully, just suitably comprises the anti-error mouth piece (tamperproof closure) of opening that described outlet and/or its material by lid are made.This whole zone that can guarantee that the mouth of drinking person will contact is covered by jacket, so drinking person can fully obtain comfortable contiguous sense.And the configuration of this permission buckle closure can be more versatile and flexible, guarantees sealing because the mating section that is used for sealing purpose of buckle closure can be fastened on the variant position of jacket.For example, if anti-error Katyuan part is designed to a tearable prominent tail that is sealing outlet, so, the user, and meanwhile for example bicycle rider can bite tearable prominent tail off with tooth by bike and open drinking container.

But jacket also can only cover the subregion that the arch teat divides, and especially covers its top.This structure, the size of particularly encircleing the teat branch can suitably be modified as by those skilled in the art that and be fit to its needs.

Contrast, jacket not only can cover arch teat branch, if desired, can also cover its outlet, and preferably also further cover the part of lid.

In a preferred embodiment, buckle closure is one and links into an integrated entity and turnover block by a joint and lid.So buckle closure and lid constitute single available plastics and carry out the molded part of integral molded plastic, like this, buckle closure is difficult for losing after this feeding lid adapted is to the container.

Certainly, also can replace with joint bonded assembly buckle closure with independent buckle closure.And, within the scope of the invention, it is contemplated that out the tight scheme of multiple possible lid, for example available snap fastener or screw thread are anchored on lid with buckle closure.

The specific embodiment

The feeding lid 10 that the container for the free-pouring material of splendid attire shown in Fig. 1 is used has a lid 100 and the buckle closure 200 as block.Lid 100 and buckle closure 200 are connected to each other with the joint 290 that is made for one with it in a side, thereby buckle closure 200 can wind the axis that is formed by joint 290 and turns over turnback and arrive the off position of its buckle closure on lid 100 from its open position shown in Figure 1.

The top of lid 100 is upper cover parts 120, is extended with tubular portion 110 downwards from the radially outward edge of upper cover part 120.Tubular portion 110 roughly is columniform, and there is screw thread 112 its inside, relies on this screw thread lid 100 can be screwed on the container with corresponding screw thread, and on the throne so as to screwing.

Also can substitute being threaded between lid and the container, for example can connect, this feeding lid and container can also be configured as one with chucking with other structure.

In the embodiment shown in fig. 1, there is sealing lip 114 on the top of the tubular portion 110 of lid 100 near the periphery of the upper cover part 120 of lid 100, and sealing lip 114 is annular and with respect to the horizontal plane downward-sloping slightly.Sealing lip 114 is pressed on the edge of vessel port and with it and seals when lid 100 is tightened on the container.

In embodiment illustrated herein, sealing lip 114 is to be configured as one with lid 100, and be with soft material for example silica gel make, different with the duroplasts that lid 100 and buckle closure 200 are used.But it should be noted that in this article: in another embodiment, sealing lip 114 and lid 100 usefulness same materials are made, and can simplify production process like this.

The upper cover part 120 of lid 100 has the ring shoulder 122 of approximate horizontal, radially inwardly being symmetrical in longitudinal centerline from ring shoulder 122 is that stepped arch teat to upper process divides 124, it is stair-stepping in its short transverse that this arch teat divides 124 diameter, and there is outlet 126 at the vault place.

The arch teat divides 124 to comprise first (or deserving to be called) bench 128, is second (or claiming down) bench 134 below it, and the both roughly is columniform, and both height are close, but the diameter of first bench 128 is less.Transition portion between the transition portion between first bench 128 and second bench 134 and second bench 134 and the ring shoulder 122 all is a circular arc, so there is not sharp-pointed edge.The upper end of first bench 128 is terminating edges 136 of outlet 126, and this terminating edge 136 radially inwardly dips down, and its top is actually level.

It also is stair-stepping that the arch teat of upper cover part 120 divides 124 inside, from diameter be minimum outlet 126 down, the arch teat divides 124 internal diameter to strengthen by rank.After the internal diameter first step below terminating edge 136 just strengthens, the columniform inside face that is essentially of one section whole axial length (short transverse) that extends beyond first bench 128 is arranged.Then, approximately further add large diameter since the transition portion between first bench 128 and second bench 134.

The lower end of first bench 128 of flexible tube grip portions 180 is formed with the block end face 130 of a ring-type, and simultaneously end face 130 defines an annular groove 132 in the top that is in second bench 134.Inner annular groove is below 132, and second bench 134 is Frusto-conical, and the bottom surface of the big end of circular cone coincides with the lower surface of the ring shoulder 122 of upper cover part 120.

It is covering cap shape basically that buckle closure 200 is designed to, and it comprises top board 210 and the sidewall 220 that extends out from top board 210.The size of this sidewall 220 is such design-calculateds: the outside face at its beginning flushes with the outer surface of the tubular portion 110 of lid 100 basically when buckle closure 200 is in the closed position.

In addition, in that side opposite with joint 290, buckle closure 200 has a groove 260 that is used to admit closure 160, (it is in the upper end to this groove 260 when buckle closure 200 is in open position shown in Figure 1, it is in the lower end and when buckle closure 200 is in the closed position) be the groove that concaves, so closure 160 can snap in it, to guarantee the fastening sealing of buckle closure 200.The groove 260 that is used for closure 160 descends both sides to limit thereon by lug 262 and projection 264.

Embodiment shown in Figure 1 has a jacket 150 of being made by thermoplastic polyester material (TPE), and the arch teat that its covers upper cover part 120 divides 124 whole outer surface and fits in the arch teat and divides 124 gabarit.

The size of jacket 150, the arch teat divide 124 size and be arranged on buckle closure 200 top board 210 the inboard cylindrical shape fastening part 280 size mutually very the coupling, so that when buckle closure 200 fastens, do not have any noise on lid 100, fastening part 280 can be fastened on the outside has the arch teat of jacket 150 to divide 124 first bench 128, just sealing outlet 126 in this way isolates from the external world with it.

In the embodiment shown in fig. 1, on the height of first bench 128, the external diameter of jacket 150 it not pressured state slightly greater than the internal diameter of the cylindrical shape fastening part 280 of buckle closure 200, like this, jacket 150 is compressed slightly when buckling as the joint bonded assembly buckle closure 200 of block, so produce force fit between fastening part 280 and the jacket 150, even make that the geometric configuration and the size of each correlated parts has little manufacturing franchise also can reach the failure-free sealing on this position, and make franchise is inevitable on a little degree at least, especially, under batch manufacturing or the relative condition with higher of production process cost, need be provided with and make franchise, in order to meeting more accurate franchise requirement.

Be for the sake of completeness purely, should be noted that: the embodiment of feeding lid shown in Figure 1 is the inside that is designed to insert with the drinking tube of a flexibility buckle closure 200, if necessary, this flexible drinking tube can be fixed in the arch teat and divide 124 inside, its outer end is stretched out in outside the outlet 126, so that the free-flowing material in the sucking-off container.

Fig. 2 shows another embodiment of feeding lid, and the embodiment with shown in Figure 1 is identical basically for it.

But be with the difference of the embodiment of Fig. 1: jacket 150 is designed to only encase the arch teat and divides 124 top, just only encases the arch teat and divides 124 first bench 128 and the transition portion between first bench 128 and second bench 134.And in this embodiment, jacket 150 usefulness low density polyethylene (LDPE)s (LDPE) are made.

In the embodiment shown in fig. 3, feeding lid 10 is designed to that the embodiment with shown in Figure 1 is identical basically.But the outlet 126 on the end face of lid 100 is provided with an anti-error mouth piece 300 of opening.This anti-error mouth piece 300 of opening constitutes the component part that this feeding is covered, and for this purposes, it is to make with the quite soft material of making jacket 150.Divide the connection lead that weakens at the edge of 124 outlet 126 that the anti-error mouth piece 300 of opening of sealing outlet 126 is connected in jacket 150 by one along the arch teat.Preferably: open the prominent tail 304 that mouth piece 300 is configured as one and can tear with anti-error.Can be easy to open container by tearing this prominent tail 304,, for example in the match of racing car and so on, also can catch in its mouth prominent tail and open container even do not sell when opening container rising.

So the anti-error mouth piece 300 of holding can guarantee that the quality of the material in the container can be subjected to the adverse effect of air or oxygen before opening for the first time at container.Also be in this case, jacket 150 can be made with thermoplastic polyester (TPE) and/or low density polyethylene (LDPE) (LDPE) or rubber, silaatic and/or flexible plastic or these mixtures of material together with the anti-error mouth piece 300 of opening.

The difference of the embodiment of feeding lid 10 shown in Figure 4 and the embodiment of Fig. 3 only is: its anti-error mouth piece 400 of opening is to be made by the material of lid 100, and is to be configured as one with injection molding technology and lid 100.This is anti-error opens outside mouth piece 400 is exposed to atop, and is connected in lid 100 or is made for one with it by a connection lead that weakens along the ring edge of outlet 126.One projects upwards from the anti-error end face of opening mouth piece 400 sideling with the same prominent tail 404 of prominent tail among Fig. 3, its material is identical with lid 100, should prominent tail 404 also be to be used to be convenient to open the container of being furnished with the feeding lid, and seal up outlet of container 126 airtightly by it, the quality that can guarantee the material in the container is not subjected to ectocine, is opened first until container.Preferably, lid 100 and tearable prominent tail 404 are to be made for one with polypropylene (PP) or polyethylene (PE) with injection molding technology.

Certainly, if necessary, also can anti-errorly open the soft material that mouth piece 400 and tearable prominent tail 404 thereof additionally cover last layer jacket 150 with what make by the material of lid 100.Especially, be to be used under the situation that can't strike with the hand open or be difficult to open at the container of being furnished with this feeding lid with hand, for example in the motion of racing car and so on, this have the design that can tear prominent tail with regard to particularly suitable.

Fig. 5 has provided the overall picture of Fig. 3 and 4 represented feedings lid.If anti-error among Fig. 5 opened mouth piece 300 and tearable prominent tail 304 removes, and the outlet 126 of exposing lid 100, Fig. 5 has also promptly represented the overall picture of the feeding lid shown in Fig. 1 and 2 so.
