Description

The bucket that comprises safety seal

Technical field

The present invention relates to a kind of container, particularly a kind of plastic container, preferably be the bucket form, lid with a closing containers, described lid has a receiving area, and when container was in closed condition, the container edge that limits vessel port engaged and remains in this zone.

Background technology

The known for a long time container of transporting liquid or pulpous state dangerous substance safely that is useful on.These container something in commons are their leakproofs sufficiently, with the leakage of the dangerous substance that prevents to betransported.Secondly, they must equip a closure member, guaranteeing the safety shutdown of container, or even under the situation of load greatly.Particularly, this container and closure member thereof also must bear contingent load under the situation of accident, for example container situation about falling from certain altitude.

This container specifically well known in the prior art comprises bucket or cydariform container, and their lid is spun on the container reliably, forms a threaded closure.In order to ensure sealing, metal holder is set in addition, it is pressed in lid on the container, prevents that perhaps threaded closure from outwarding winding.Also have such closure system, after it is positioned on lid on the container, connect in case stopping leak leaks with flange.Also known in addition in system bonding or welding lid or closure member, perhaps bonding therein or sealing film that welding is additional.

The common shortcoming of these containers or bounded system is, they are very complicated and be difficult to grasp; For such object of the highly automated control of needs, comprise that enclosure method has problems especially.

Summary of the invention

Therefore, but the purpose of this invention is to provide a kind of leakproof and container safety shutdown, it is suitable for the dangerous substance of transport liquid or pulpous state, and the manufacturing of described container and grasp are very simple and effective.

The realization of this purpose is the container that has the feature of claim 1 by a kind of.Useful embodiment forms the theme of dependent claims.

Container of the present invention, preferred configuration are bucket or cydariform, and it has a lid that is used for closing containers, and described lid has therein a receiving area, the edge joint of vessel port and remaining in this zone in the time of in off position.In this scope, container of the present invention is based on known container.

Yet compared with prior art, the present invention adopts diverse scheme to solve existing problem.Container of the present invention by provide failure-free can interconnective latching member (catch member) and corresponding interactional sealing surfaces realize, can be firm and closing containers closely.Employing is connected with the failure-free that the sealing surfaces that is fit to forms by latching member, guarantees to grasp and make simply.Therefore guarantee effective use of container.

The failure-free that is formed by latching member connects preferred configuration, if to small part lid or part container when destroyed, the lid of container just can only be released.Therefore the user has and can confirm to have first person's of opening assurance, because it is unbroken to have only the container of never opening to be only, the container through opening can have a ruined lid or ruined container.

According to a preferred embodiment of container, the receiving area of lid and the edge joint of vessel port promptly form on the reliable bonded assembly latching member at the closure member of container, and sealing surfaces is designed so that to be placed on and covers; Be that closing containers is by lid is realized with respect to the container translation.Particularly advantageous is that lid is to be pushed to or to clip on the container from the top simply.This allows container automatically to close by machine, because the operation of translation or promotion or folder can easily be carried out on machine.

According to preferred embodiment, at least two, receiving area and the vessel port edge of the latching member more than three or three to being arranged on lid preferably because a plurality of latching member covers at several somes place fastenedly to making, therefore helps closing containers securely.Term " latching member to " is not meant the latching member that has only two to lock together reliably here, but can refer to a large amount of latching members, yet considers that they are similar configuration and identical manner of execution, and it is right to be considered to be a latching member.For example this is suitable for the latching member that formed by subdivision.

Preferred embodiment according to container, be designed at least two, preferably the latching member more than three or three is right, it is right to make at least one formation of these latching member centerings be different from another latching member, in this mode, throw off latching member required motion is different from another latching member to required motion.This means that not every latching member is to the mono-motion at the edge of the receiving area just covered of a part that can be by lid or vessel port and throw off at once.On the contrary, need different motions to make latching member, need to guarantee the motion of a complexity to unitary release.Provide at least two kinds of latching members particularly useful to being proved, this needs opposite motion to throw off latching member.Useful especially scheme is, for the purpose of opening, a part that for example needs the receiving area not only outwards but also inwardly motion.Therefore this method exceeds the different particularly opposite motion of needs, is positioned at the circumferential latching member of opposition side with disengagement.At this, this is that significantly different latching member is right, and it is contiguous mutually to this means them, for example one above another.

The different motion of inhomogeneous needs is set throws off the latching member of latching member having additional advantage, in this way when latching member connects forming failure-free, also in the receiving area of lid and the sealing surfaces that is provided with on the vessel port edge produce a suitable clamping action.Even realize, but as described abovely different latching members is set to guaranteeing at the reliable contact pressure that adds that keeps of many stress occasions by the pressure that the lid and the appropriate size of vessel port make sealing surfaces press mutually.

Except that separating the sealing surfaces that is provided with, it is favourable that the sealing surfaces that forms reliable bonded assembly cooperation is provided on latching member, because particularly adopting inhomogeneous latching member right, need the situation about moving of different directions can realize interlocking to throw off latching member, it causes the latching member of positive lock to press against to a certain degree mutually, and therefore forms sealing surfaces.

According to a preferred embodiment, particularly with under the form of packers of inserting or spray, additional sealing member can be arranged in the receiving area of lid and/or in the vessel port edge.

In order to realize being called as the assurance of opening for the first time, can also be advantageously in the receiving area of lid and a predetermined disengaged position is provided in the vessel port edge, easily be removed in order to guarantee safety and those zones of bonded assembly that can not discharge.Particularly, advantageously in the receiving area of lid and a predetermined disengaged position is provided on the vessel port edge, its right part receiving area and/or part lid of latching member that causes having difference in functionality is removed, because this class latching member is to preventing that especially discharging failure-free connects.

According to a preferred embodiment, the cross-sectional plane of the receiving area of lid is U-shaped basically, and open in the bottom receiving area, so that the edge of storage container opening therefrom.The leg of U-shaped receiving area centers on the vessel port edge, and keeps securely by latching member in the mode of positive lock.While sealing surfaces quilt is force together securely, therefore guarantees sealing effectiveness.

Arrester hook, latching member (latch), engagement groove of a large amount of various combination etc. certainly are provided, and the sealing surfaces of configuration compatibly, in the preferred embodiments of the present invention U-shaped receiving area that leg forms in the leg and outside by, two latching members or arrester hook are arranged outside, described two latching members or arrester hook and two latching member mutual actions on the outside at the edge of vessel port on the inboard of leg.In its outside, the outer leg of U-shaped receiving area also has another arrester hook, the cut part mutual action in itself and the vessel port edge, and described cut part is arranged on the double-walled portion at edge, on the outer arm at edge.By arrester hook or latching member being positioned at the inboard and the outside of the outer leg of U-shaped receiving area, and at corresponding cut part or the latching member of the fringe region configuration of vessel port, it is right to form two kinds of different latching members, its difference is, can discharge by outwards moving outer leg the locking that forms by a kind of latching member, and in order to discharge by the latching member of another kind of latching member to forming, then outer leg must move inward.

The simple configuration that this latching member is right is guaranteed easily lid to be placed on the container by moving vertically downward on the one hand.On the other hand, these triple locking systems guarantee that lid is fixedly mounted on the container.Inhomogeneous latching member opposite is opened mobilely to adopting, and guarantees more can not be removed at non-destructive situation lower cover.

Can easily open container in order not use any special special tool, and guarantee that lid easily is covered, design one contraction flow region on the outer leg of U-shaped receiving area makes to form a single-piece hinge or film hinge in this zone that it constitutes the bottom of outer leg.The effect of this film hinge is, the bottom of outer leg can be carried out when closing containers, and promptly when putting when covering, required passes through latching member or arrester hook and downcut moving of part.Film hinge is a contraction flow region, provides in addition by using parting tool such as knife simply, takes off the possibility of this bottom along film hinge.Because the right latching member of two kinds of different latching members of receiving area preferably is arranged on the bottom of outer leg, so have only a latching member taking off bottom still reservation later on.This last latching member can discharge by the outer leg of mobile slightly receiving area.The latching member of the reservation that this is single allows to continue to use container is opened for the first time after and closed container again, though it does not provide the firm sealing of assurance for the first time.The latching member of the reservation that this is single also allows after container is opened for the first time to continue to use and closed container again, though it no longer guarantees the firm sealing that guarantees for the first time.

For container is evenly sealed, if preferably latching member or latching member are to being oriented to circumferentially around vessel port and lid; Then by recess, the latching member of interruption such as piston ring land or subdivision can cause forming corresponding a plurality of latching member, though as limiting in the present invention, it is right to advocate evenly to seal and adopt a latching member or two latching members to constitute a latching member.

Because above-described method, container of the present invention can adopt the material of standard and not need special method.Polyolefin-based plastics are preferred, particularly polyethylene and polypropylene.Be preferably used for the selection that additional seal helps not require material, though, may have the specific (special) requirements of the selection of relevant material according to use occasion.The size of having only parts for example wall thickness must be adjusted, and uses being suitable for, thereby also bear required power under the situation of unusual load, for example in accident.

The specific embodiment

Fig. 1 represents the lateral plan according to the partly cut-away of the container of closing 1 of the present invention, that is to say with lid 2 to be placed on the container 1.Container 1 is the form of bucket in the embodiment shown, for the ease of carrying a twist grip 27 is positioned on the container.

In the part of the partly cut-away of Fig. 1, can see that container 1 has the bottom 30 that slightly inwardly curves arch, has feet 31 at its outward flange; Therefore between the area supported of bottom 30 and bucket, there is a little space.It is one tapered a little that container 1 also has, but come down to columniform outer shape, makes it possible to be inserted in empty container.

Fig. 2 a represents to cut details partly open to 2c, and the edge 3 of receiving area 4 and vessel port is in the different phase that container 1 cuts out.

In Fig. 2 a, container still is opened fully; Lid 2 is put down gently in vessel port, promptly on the edge 3 of vessel port.Can be clear that in this detail view, be U-shaped in lid 2 receiving area, periphery place 4 basically, and open in the bottom receiving area, so that from the element 9 at the edge 3 of there storage container opening.Therefore receiving area 4 has two

legs

5 and 6, promptly outer leg 5 and interior leg 6, and they are connected to each other at join domain 7 places of the bottom of U-shaped.The inside of lid 2 links to each other with receiving area 4 through lid connecting portion 22; The interior leg 6 of lid connecting portion 22 and receiving area 4 forms an opposite U-shaped, so covers the top that 2 inside 32 is positioned at receiving area 4.Receiving area 4 forms the stacked edge of a circumference in the embodiment shown, makes the container 1 close can one be stacked on above another.Mainly prevented respect to one another moving by receiving area 4.

The inboard of 4 outer leg 5 is provided with two

latching members

12,13 in the receiving area, on the outside of leg 5 almost is outside in its bottom one arrester hook 14 to be set.Latching

member

12 and 13 and arrester hook 14 along outer leg 5 approximately equally spaced from opening.Near in the middle of the latching member 13, the zone between latching member 12 and latching member 13 is provided with a contraction flow region, thereby forms holistic hinge 15 or film hinge 15 on the outer leg 5 of the receiving area 4 of U-shaped; Simultaneously, the centre of the close latching member 13 in the inboard of leg 15 forms a groove 20 outside.

Mutually externally the side of the interior leg 6 of leg 5 inboards form a level and smooth sealing surfaces; There is an angle on the sealing surface with respect to vertical direction.

In the zone 7 of the connection leg 5 of the receiving area 4 of U-shaped and 6, the sweep 29 in the receiving area 4 of U-shaped provides a space that is used to hold packing seal, and the sealing pad is not shown.

In vessel port place, container 1 has the edge that a bottom is a double-walled.In this bottom at the edge 3 of container 1, except interior element 9, also has an external component 8 that forms double-walled.Therefore the edge 3 of container 1 is made of two parts, i.e. first above, and wherein edge 3 comprises element 9 and is single wall, the second portion below, wherein edge 3 comprises external component 8 and interior element 9, and to make it be double-walled.Two

arrester hooks

10,11 are formed on the outside of element 9 at first top at the edge 3 of container 1, and its cross-sectional configuration is for being the triangle protrusion basically.Second bottom at the edge 3 of container 1 has opening 25 at the place, top.Simultaneously, external component 8 forms cut part 21 at the edge of opening 5.

The inboard of the interior element 9 at the edge 3 of container 1 forms the sealing surfaces 17 on a level and smooth plane, and its sealing surfaces 16 with the receiving area 4 of lid matches.

Close closed procedure such as Fig. 2 b, shown in the 2c.Fig. 2 b is illustrated in when covering 2 closing containers 1, and element 9 is inserted into the receiving area 4 of U-shaped, and latching member 13 at first slips over arrester hook 10, and the lower end that has the outer leg 5 of arrester hook 14 simultaneously is introduced in the opening 25 of double-walled portion at edge 3 of container 1.

When covering 2 further closing containers 1, shown in Fig. 2 c, latching member 12 also slips over arrester hook 10, and latching member 13 slips over second arrester hook 11.Latching

member

12 and 13 and the configuration of

arrester hook

10 and 11 make them have complementary inclined surface, this surface allows latching member to slip over hook on closing direction, thereby prevents that by failure-free locking latching member on-slip returns.Simultaneously, closing when finishing, the bottom of leg 5 is contained in the double-walled part at edge 3 fully, arrester hook 14 rest in downcut part 21 below.Obviously, in closing closed procedure, the bottom 33 of outer leg 5 is braked hook 11 on the one hand to external pressure, and the bottom 33 of outer on the other hand leg 5 is braked hook 14 and inwardly bends, so that it can be inserted in the opening 25 at double-walled edge 3.Specifically this also may finish by the configuration of film hinge 15, and it allows bottom 33 according to carry out different moving with 2 stages of closing of lid.

In buttoned-up status, obviously, latching

member

12 and 13 is connected with

arrester hook

10 and 11 formation failure-freies on the one hand; Arrester hook 14 is connected with cutting-out part 21 formation failure-freies on the other hand.Right in order to discharge all three latching members, be necessary outwards to move outer leg 5, throwing off latching member to 12 and 10 and 11 and 13, and inside to move for throwing off latching member be necessary to 14 and 21.Owing to be that inclined surface is bearing on the latching member 11, when a leverage effects acts on the direction of locked position of coupler, latching member is further strengthened 14 and 21 latch effect, therefore, do not destroy receiving area 4, promptly not cutting off or take off bottom 33 along film hinge 15 can not releasable.Have only when bottom 33 by the cut-out mode when film hinge takes off, can be released the 12 and 10 residual latch portion that form by latching member.This has additional advantage, and promptly after container was opened for the first time, everyone can see that container still is suitable for continuing to use and can cut out once more because bottom 33 is retained in the double-walled part at edge.

Except form latching member to, because sealing

surfaces

16 and 17 contact, particularly green phase is suitably adjusted for the size at the edge 3 of container 1 or container and is covered 2 size, and the locking mechanism between receiving area 4 and the edge 3 is adjusted to suitable configuration, make

sealing surfaces

16 and 17 press together, therefore when container closure, produce sealing.In addition, to 12 and 10 also with the sealing surfaces force together, in the case, sealing surfaces 18 and 19 is shown in Fig. 2 c to latching member particularly for latching member.Buckled zone 29 in the U-shaped receiving area can comprise an additional unshowned packing seal, and its upper end by element 9 is compressed against the join domain 7 of receiving area 4, therefore produces additional sealing effectiveness.

From Fig. 2 c as can be seen, by

latching member

13,11 failure-freies that form are connected, further strengthened by a groove 20 that is arranged on film hinge 15 inboards, arrester hook 11 can additionally join in the groove.

The cross-sectional figure of details of Fig. 3 and 4 presentation graphs 2b and 2c in each case, is along line D-D.When Fig. 3 and 4 was illustrated in container 1 and closes, how element 9 was bonded between outer leg 5 and the interior leg 6.Between the external component 8 that cutaway view is clear to be illustrated in edge 3 and the interior element 9 and cover 2 interior leg 6 and cover 2 edge and separator 23 and reinforced wall 24 are set between being connected 22, so second time double-walled portion at edge 3 is that the top of rectangle has opening 25 at cross-sectional plane basically.Therefore the lower area of outer leg 5 is provided with additional recess, and dividing plate 23 can engage in this recess down in off position.

Fig. 3 and 4 is similar to Fig. 2 c, and expression is hinged on the part handle of the double-walled portion at edge 3 equally.

Fig. 5 represents to put the transparent view that covers 2 container 1.This transparent view has represented that well how handle 27 is hinged to the double-walled portion at edge 3 rotationally, particularly is hinged on the external component 8.

In this figure, can most clearly see dividing plate 23, reinforced wall 24 and opening 25.Fig. 5 also represents to pile up the configuration of supporting member 26, and it is arranged on the outside of container 1,3 the bottom at the edge, the hinge-point of contiguous handle 27.Fig. 7 represents more clearly how pile up supporting works.Lid also is equipped with a pull unit 28 on 2, after the bottom 33 of the outer leg 5 of receiving area 4 (as implied above) has removed, can take off covering 2 with pull unit.

Fig. 6 represents container 1 and lid 2 fragmentary, perspective views that have been removed equally.As can be seen from the figure, the bottom of receiving area 4 is provided with the outer leg 5 of arrester hook 14, and it has a plurality of recesses 34, and therefore outer leg 5 can engage with opening 25, and dividing plate 23 has the space in the zone of recess 34.

Two containers 1 that Fig. 7 represents to pile up mutually with the lateral plan of partly cut-away and 1 '.That piles up how supporting member 26 and 26 ' be to work represents clearlyer here, and they rest in the top of element 9 when container is nested with.The distribution of load that this has prevented the bucket extruding that is nested with and has guaranteed to limit.The lateral plan of Fig. 7 knows that also the face of land shows that

arrester hook

10 and 11 is to be designed to circumferential rib on the element 9 at edge 3.

From Fig. 8 a and 8b as can be seen, not only container can be nested with, and lid also can be nested with, shown in Fig. 8 a.Shown in the details of Fig. 8 b, the join domain of receiving area 47 forms circumferential stacked edge, be arranged in the lid 2 of top ' the lower end of leg 6 can join the edge to.But in the cross-sectional figure of Fig. 8 a and 8b, clearly show a reinforced wall 23 and stop interior leg 6.Lack than the lower end of interior leg 6 the feasible lower end that has the leg 5 of arrester hook 14 of the size of outer leg 5, and therefore outer leg 5 ends at the top of the join domain 7 that is positioned at following lid 2.

Fig. 9 represents to cover 2 top view, and the periphery of lid 2 that has receiving area 4 is by reinforced wall 24 and recess 34 and arrester hook 14 even five equilibriums.Certainly, though form many arrester hooks around periphery by recess 34,, these arrester hooks 14 are to be understood that it is to be used as a latching member, because particularly all arrester hooks 14 and circumferential cutting-out part 21 mutual actions, it is right therefore to form a latching member.Certainly, by analogize and as the meaning of term used herein, a latching member is to being formed by a large amount of arrester hooks and latching member.
