Preferential embodiment narration

Although the present invention can have many multi-form embodiment, however only open some special shape of this specification sheets and accompanying drawing as example of the present invention.But the present invention is not limited to described embodiment.In additional claims, pointed out scope of the present invention.

For ease of explanation, gland of the present invention is described by vertical position, and the term that uses is for this position as upper and lower, level or the like.But it should be understood that gland of the present invention except described position, can take over where the position is made, stores, transports, used and sells.

Fig. 1 represents that the present invention shows first embodiment of infringement gland when full-shut position, and the gland shown in it is represented with label 20 usually.Gland 20 is suitable for being installed on the container that traditional opening of being determined by neck (not shown) or other suitable members can be arranged on the container (not shown).

Gland 20 comprises gland pedestal or the matrix 24 that is fixed on the container.Pedestal 24 comprises cylindrical substantially circumference wall 26 and roughly is horizontal gland wall or cover plate 28 (Fig. 3 and Fig. 5), and cover plate 28 extends across pedestal 24.The centre portion of pedestal cover plate 28 is thicker, so peripheral part of cover plate 28 limits a peripheral land.

The cylindrical wall 26 of gland pedestal 24 is suitable for cooperating with the neighboring of spiral (having suitable structure throws off with the gland that prevents to assemble) with container neck (not shown) top around the vessel port.Other suitable adapting device (for example buckle pearl) also can adopt, so that gland pedestal 24 is fixed on the container.In addition, in some application scenarios, gland pedestal 24 can disengageably not connect container, perhaps constitutes one with container.

Gland pedestal 24 comprises the escape route 40 by cover plate 28 (Fig. 5).Gland passage 40 is surrounded by hollow exhaust tube 39.Pipe 39 protrudes upward from main body cover plate 28.

Be the inward flange of the container neck that engages the container orifice place, traditional seal ring 45 faces down in the cover plate 28 and stretches out, to realize tight seal.

Optimal scheme is to utilize hinge means or hinge 52 (Fig. 5) will cover 50 edges that are hinged to pedestal 24.Have on the lid 50 and damage recognition component or element 54, this element must be able to separate, and hereinafter will explain in detail, so that the path of open and close lid 50 is provided.Lid 50 limits three holes 55 (only representing two holes in three holes among Fig. 5), and each hole 55 is suitable for seating part element 54, covers on 50 so that element 54 is fixed to, as hereinafter describing in detail.

Lid 50 is suitable for rotating between (1) make position (Fig. 1) and (2) open position of leaving from make position, the article that make position prevents to be stored in the container flow out by gland, and open position can make the article that are stored in the container distribute (Fig. 3 represents to partially open the position) from the pedestal discharge orifice.

In the embodiment shown in Fig. 1-9, hinge 52 is US Patent NO.4, the moving hinge of the card of disclosed traditional type in 403,712.If the employing hinge, then hinge 52 needn't necessarily need be used card ejector half hinge.Can adopt any suitable connection cover 50 and the hinge apparatus of pedestal 24 according to special application need such as attractive in appearance, manufacturing process or the like.

Preferably lid 50 and the suitable thermoplastic material of gland pedestal 24 usefulness such as polypropylene or polyethylene molding are become integral structure.But cover 50 and pedestal 24 also can constitute independent part, preferred design becomes the continuous assembly with suitable connection hinge apparatus, so that lid can open and close.Itself does not constitute part of the present invention the detail design of hinge and operation.

Lid 50 preferably includes central cover plate 58, and has the circumference skirt section of being determined by central cover plate 58 peripheries 60.The skirt section 60 of lid has the bottom surface 62 (Fig. 5) that basal surface is covered in qualification.As shown in Figure 5, skirt section basal surface 62 is suitable for being placed on the annular shoulder of circumference of pedestal cover plate 28 when lid is closed.

In the embodiment shown in Fig. 1-9, lid 50 also comprises seal pin or the element 68 (Fig. 5) that stretches out from central cover plate 58.When lid 50 closures (Fig. 5), the discharge orifice that is suitable for entering the hollow tubular 39 that stretches out by pedestal central cover plate district 27 of packing element.This just is specially adapted on the liquid container.

But it should be understood that pedestal exhaust tube 39 and lid packing element 68 do not need to be arranged to graphic form, perhaps do not need fully.If gland 20 is to be applied to liquid, can adopt so as come the pedestal 24 of sealing plug stopper 50 around other devices that cover skirt section basal surface 62.If gland 20 is the containers that are used for pill or other Individual Items, so for provide lead to container than large through-hole, then can save the major part of pedestal cover plate centre portion 27.In this case, to save exhaust tube 39 and lid packing element 68 certainly.

Later-model latch mechanism is set makes and cover 50 and remain on make position, even after element 54 is removed, can also prevent that children from opening gland (hereinafter will describe in detail).Specifically, in the front of gland 20, at hinge 52 opposite position radially, pedestal 24 is provided with elasticity shank of the key 70 (Fig. 1-3 and Fig. 5), this shank of the key by the pedestal periphery inwards the pedestal cover plate 28 at position protrude upward.Lock handle 70 has upwardly extending and ventricumbent shoulder 72 (Fig. 5).Handle 70 is very hard, though be not possible, small children is known very difficult with pointing towards hinge 52 backward with lock handle 70 bendings or deflection.

The top of locking member 70 has crooked far-end 74, and the front portion of the locking member 70 of shoulder 72 tops stretches out, and is slight convex by the thin-wall far-end to the outward flange of shoulder 72.This just limits and relies on the convex surface 76 of covering 50 effects, and this point is hereinafter explained.Handle still has rear surface, top 78 (Fig. 5).

Gland plate 58 is installed aperture 80 (Fig. 3) inwards at the lid periphery in the middle of the lid, in order to lay handle 70 (Fig. 5) when lid is closed.Open at the end at bottom surface (promptly the covering skirt section basal surface 62) aperture 80 that covers.

Limit by intilted flat last front face 82 before the aperture 80.When lid 50 forwarded complete make position downwards to, wall 82 played the effect of the convex surface of the convex surface 76 that engages handle.When convex wall 82 and handle surface 76 engaged, to regulate, lid 50 moved to complete make position to handle 70, wherein skirt section seat surface 62 engaged with base cover plates 28 to post deflection.

The upper limb of lid convex wall 82 ends at the mortise lock surface 86 (Fig. 3) that level is arranged, this be from handle 70, the front elevation of ventricumbent shoulder 72 slightly beneath to.Therefore, when lid 50 is located in make position fully, because the intrinsic elasticity of handle material makes handle 70 turn back to its normal non-inflection point.When lock handle 70 has been got back to the position that is not subjected to stress normally (as shown in Figure 5), lock handle shoulder 72 covers on lid mortise lock surface 86, and unless lock handle 70 rotates backward for the first time, 72 preventions of lock handle shoulder are covered 50 and upwards rotated.

As shown in Figure 5, on front elevation, the top surface of the lid of the either side of handle 70 is a bit larger tham the top surface of handle far-end 74 when lid is in complete closure.The gap around handle 70 tops and the overall width of handle 70 are quite little.This has just reduced the exposed parts of the handle 70 of contact teenager teeth, and prevents the crooked backward handle 70 of children.Have again, the little gap around the handle 70 stop teenager teeth enter handle shoulder 72 below.

Yet, open gland for ease of the user that grows up, lid 50 defines around aperture and the finger-type of extending from aperture enters recess, and (Fig. 2) determined by concave curved surface 90A that separates and 90B in this slot part ground.The size of curved surface 90A and 90B is fit to the width of normal adult human finger, so the adult can be placed on finger near the upper forepart of lock handle 70, and promotes lock handle 70 backward.But total depth and the width of adjacently situated surfaces 90A and 90B are very little, so that reduce to contact the exposed parts of the handle 70 of teenager teeth, and prevent that children from bending handle 70 backward.

In addition, as shown in Figure 2, preferably make near recessed below, top lid central cover plate 58, the top of lock handle far-end 74 a bit.Also have, as shown in Figure 5, the surrounding zone of lid 50 comprises skirt section 60, extends outwardly beyond the front portion of lock handle 70, in order to prevent the front portion of teenager teeth contact handle 70.

For helping adult user to open gland, lid 50 comprises pair of finger contact surface 92 (Fig. 1 and Fig. 3), and a surface 92 is on a side at mortise lock position, and a surface 92 is on the opposite side at mortise lock position.Each finger contact surface 92 is determined by shallow indentation on skirt section 60.Indentation 92 extends around cover on the either side of lid aperture 80.Each finger contact surface 92 form one limit the indentation trailing portion towards outer hydraulically smooth surface.

Preferably each indentation and relevant finger contact surface 92 are whole extends to bottom surface, skirt section 62, but ends at below the top in skirt section a bit.The end of respectively pointing contact surface 92 of close aperture 80 carries out the transition to and covers skirt section 60 outer peripheral faces in addition.

For making the user that grows up apply a power of upwards opening on lid 50, each finger contact surface 92 stretches out gradually, the distance of increase and lid bottom surface 62, as shown in Figure 6.Finger contact surface 92 stops along top margin, and this top margin along lid base, skirt section forward or stretch out.But finger contact surface 92 does not stretch out the enough degree of depth of periphery surface, snap-in in the time of can not being proposed by children's tooth.Be that indentation is very shallow and tilt or crookedly can not effectively engage in the mode of non-slip with the upper and lower labial teeth that causes children, and can not cover 50 direction and apply enough big power levering up from pedestal 24.

In addition, other parts of lid periphery between the two finger contact surfaces 92 and between each surface 92 and the hinge 52 are not stretched out the periphery surface of enough degree of depth, snap-in in the time of can not being proposed by children's tooth.

For increasing 20 couples of children's of gland resistance, finger contact surface 92 does not extend in the front portion of lock handle 70.Promptly the district of mentioning by 92 representatives of each finger contact surface opens lid and finishes opening operation two obvious different positions to require the user from lock handle 70 and aperture 80 side travels one q.s.Therefore lock handle 70 must engage in a position of lid 50, and when lock handle deflection, makes by the finger contact surface 92 of mentioning one or two independent side travel and covers 50 and must open.This operating sequence is a difficulty and flurried to small children.

The surface that preferably is right after the skirt section 60 of mortise lock face 86 (Fig. 2) below between finger contact surface 92 is vertical and level and smooth basically, and from lock handle shoulder 72 (Fig. 5) a little forward, surface or edge occur so that eliminate or reduce, these surfaces or edge can be separated or twist the structure of lock handle 70 at this position by the contact of children's tooth.

In addition, outstanding at least as far as lid bottom surface 62 outside circumferential from the structure at pedestal 24 positions that hinge 52 extends.The front of best pedestal 24 stretches out also more than lid bottom surface, skirt section 62 along circumference, shown in Fig. 1 and 5.Because the generally outstanding lid 50 that surpasses closure in the front of pedestal 24 is so gland has bigger manufacturing (molded) tolerance.In other words, molded bigger slightly lid still can not make the front of lid along the outstanding pedestal 24 that surpasses of circumference, and one of unlikely generation can make the lug that stretches out of teenager teeth contact.Gland has just possessed the ability of easier suitable manufacturing process like this.

Gland of the present invention provides improvement to child safety.Because the gland of most preferred embodiment has the mortise lock structure of insertion, and drowning has and stretches out the enough degree of depth of periphery surface, can not be contacted by teenager teeth, so, resistance by children's tooth pry-off cap is very big, the configuration of mentioning position and lock handle position loam cake at finger is smooth, has eliminated the lug of sharp edges, thereby prevents children's tooth so that the gland distortion contacts gland with distortion effectively with the mode that gland is opened.

In addition, the configuration at the recess position around the lock handle is covered 50 top and front portion if children bite, and children's tooth just impels the gland lid more near the gland pedestal so.The front surface of lock handle 70 has smooth curved surface profile, stops teenager teeth to contact effectively.On the other hand; Utilize some device, as be inserted in some external tools between handle and the lid, the lock handle rear surface engages will just play the effect that lock handle engages more with lid more forward that promotes.

Be installed to and cover 50 top as shown in Figure 1 damaging recognition component 54, to prevent to be prevented from leading to the mortise lock work of handle 70.Damaging recognition component 54 comprises and must tear to appear gone to the part of handle 70 from covering 50 tops.As shown in Figure 2, fixed part 104 is still stayed on the cover plate 58 behind two preceding fixed parts 102 and one when damaging recognition component 54 and torn.This just provides a kind of information, and the part of promptly damaging recognition component 54 is removed.It informs that user's gland 20 is in and has been in open mode, so gland may be opened really.Remain in fixed part 102 on the gland lid 50 and 104 function like this as damaging identification marking, and proof no longer can guarantee the globality of gland.

Damage recognition component 54 and comprise the central authorities of mentioning tongue piece 108 after having, straight disc-shaped part or dull and stereotyped 106 and the preceding mortise lock backplate or the side plate 110 that dangle downwards.As shown in Figure 1, mortise lock backplate 110 extends and covers mortise lock or handle 70 to prevent contact.As shown in Figure 4, the following muscle that stretches out downwards 112 that separates a little inwards with mortise lock backplate 110 that preferably also comprises of element 54.Muscle 112 is suitable for extending downwardly into the back of handle 70, in order to prevent producing motion backward in element 54 removals with pull end 70.

The inner face of element 54 also comprises two additional parallel muscle 116 that separate (one of them muscle can be seen) along the inner face of backplate 110 in Fig. 5.When attempting to mention backplate 110 and appear handle 70 on the mortise lock position, these muscle transmit the straight disc-shaped part 106 of moments of flexure to element 54 by backplate 110.The inner edge of each muscle 116 cooperates with front surface the place ahead of handle 70, and contacts with the front surface of handle 70.

Comprise the plate 106 of mentioning tongue piece 108, mortise lock backplate 110, muscle 112 and the muscle 116 common essential parts that constitute gone to the portion that damages recognition component 54.Gone to the portion of element 54 links with the transom of introducing below covers on 50.

As shown in Figure 2, there are two holes 120 front portion of element 54, and there is a hole 122 at the rear portion.See Fig. 6 and Fig. 7, before each fixed part 102 in the hole 120 peripheries link and cover, then fixed part 104 in the hole 122 peripheries link element 54.

As shown in Figure 4, near the fixed part 102, plate 106 limits partial circle cylindricality part or bead 130 before each.Each bead 130 is the circular arc of about 300 degree.Each bead 130 has been strengthened 120 surrounding areas, hole.

The plate 136 of support loading roughly triangular in shape (Fig. 6 and Fig. 8) is connected the base of partial circle cylindricality bead 130.In most preferred embodiment, element 54 usefulness thermoplastic materials (as polypropylene) are molded as total.Therefore triangular plate 136 is appended to disk 106 as the whole extendible portion of half-cylindrical bead 130.Triangular plate 136 is at leg-of-mutton each place, angle connecting flange 130.Connection between each semicolumn part 140 of bead 130 and triangular plate 136 is quite weak, thereby forms fragile connection 144 (Fig. 8).

Being faced down by triangular plate 136 following, what stretch out is fixed leg 150.Fixed leg 150 has the enlarged head 152 of band truncated cone shape far-end 154.Each fixed leg 150 is suitable for being placed in two of covering in the holes 55 (hole among Fig. 5 in the indication window 55).Each fixed leg 150 is concentric with component hole 120.When element 54 was assemblied on the gland lid 50, each fixed leg was also concentric with the assembly opening 55 that covers.

The following larger diameter end 152 to post of slave plate 136 be equal to or greater than the thickness that covers middle body 58 apart from x (Fig. 8).Preferably make the diameter of the diameter of axle (head 152 tops of expansion) of post 150 less times greater than lid hole 55.The head 152 that enlarges also must be greater than the diameter in hole 55.Bevelled truncated cone far-end 154 is convenient to post 150 put into and is covered 50 hole 55.The diameter of the following far-end of the conical end of fixed leg is less than the diameter of lid assembly opening 55, so that put into hole 55.When laying, put into bigger head 152 for suitable, hole 55 temporarily is out of shape (expansion).The cylinder with the enlarged a little that adapts to fixed leg 50 is continued to enlarge slightly in hole 55.

The compressive force that produces in gland assembling place when the intensity of the fragile connecting bridge 144 between triangular plate 136 and the bead 130 is enough to adapt to inserting side sheet-pile 150.But when when applying enough big tension force and/or bending force on element 54, each fragile connecting bridge 144 will rupture because of upwards mentioning plate 106 (by grasping tongue piece 108 (Fig. 2 and Fig. 7)).Plate 106 disconnects on plate 136 at fragile part 144 places, and therefore preceding fixed part 102 (Fig. 4 and Fig. 6) still is retained in and covers on 50.Because the head 152 that enlarges on the plate 150 makes fixed part 102 avoid pulling out from covering 50.

When fragile part 144 ruptured, staying remaining fixed part 102 that covers on 50 was not that can't see or dangerous sharp keen outshot basically.

If desired, each post 150 can provide an easier outshot of seeing in the plane than triangular plate 136 by protruding upward above the triangular plate 136.In the embodiment of this unshowned replacement, the height of the upwardly projecting portion of post 150 preferably is less than or equal to the height of element 54 upper surfaces.

Back fixed part 104 can have identical structure with the above preceding fixed part of reference Fig. 6 and Fig. 8.But in Fig. 7 and back fixed part 104 shown in Figure 9, the difference of its structure has been to cancel the triangular plate 136 that adopts in the preceding fixed part 102.Near the fixed part 104 of back, plate 106 defines the cylindrical bead 160 that faces down and stretch out in the element 54, thereby defines the continuation in hole 122.

Internal diameter by hole 122 radially extends three muscle 162 inwards.Each muscle 162 all have bevelled end face 164 (Fig. 9) and towards bottom surface 166.

The end face of post 170 is converged in the bottom surface 166 of each muscle 162 at fragile connecting bridge 168.The size of muscle 162 and fragile connecting bridge 168 enough provides enough fillers for molding process, and the suitable disruption characteristic of the element 54 that adapts to the described gland of assembling is provided.

Post 170 has band expansion termination 172 truncated cone or bevelled or distal face 174.The lower end diameter of conical surface 174 is less than the diameter of gland lid placed hole 55, but the diameter of termination 172 is greater than the diameter in gland lid hole 55.Optimal scheme is that the column diameter of 172 tops, termination post 170 inwards also is a bit larger tham the diameter that covers hole 55.But in post 170 patchholes 55, also need to produce simultaneously some distortion.Yet in order tightly post 170 to be placed in 50 li on gland lid, because the elasticity of lid material makes the size in hole 55 be reduced to diameter less than head 172.

With reference to Fig. 7 and Fig. 9, should be appreciated that each fragile attaching parts 168 is positioned at the most external of post 170, best post 170 and hole 122 centerings, the column diameter of post 170 is slightly less than the diameter in hole 122.

Three fragile parts 168 are linked post 170 on the muscle 162, and three fragile parts 168 are very little so that when upwards mentioning plate 106 with enough power, frangible portion is divided fracture.The fracture of post 170 and muscle 162 connects to define and remains in the back fixed part 104 (as shown in Figure 2) that covers, in order to the damage evidence of and leading portion 102 same way as to be provided.

Element 54 positions of fragile part 168 tops (rear pillar 170 tops) and fragile part 136 tops (front pillar 150 tops) have constituted gone to the part of element, and its function conduct prevents the side plate near mortise lock handle 70 when in place.Utilization is mentioned tongue piece 108 and can be gone part or side plate to move.The discardable part of going.Manifest mortise lock handle 70 then and cover 50 so that operation is unclamped.

Fixed part 102 with 104 together with each relevant fragile part 144 and 168, can be called and link the transom of gland lid 50 damaging recognition component.When fragile part 144 and 168 is broken, gone to the part of element is mentioned, the part that retains that covers transom only includes only fixed part 102 and 104.

The embodiment of second best at present damage identification gland of Figure 10-14 expression the present invention.Gland is indicated by the reference number among Figure 10 and Figure 11 220 usually.Gland 220 is suitable for being contained in and has by on neck (not shown) or the determined traditional open containers of other suitable construction (not shown).

Gland 220 is included as gland pedestal or the main body 224 that is fixed on the container.Pedestal 224 comprises roughly cylindrical circumference wall 226 and crosses the horizontal gland cover plate 228 (Figure 11) that is generally of pedestal 224 extensions.The middle body 227 of pedestal cover plate 228 extends upward and forms the vertical platform of stepped appearance that surrounds cover plate 228 circumferential edge bottoms.

The cylinder wall 226 of gland pedestal 224 is fit to the neighboring, container neck top (the neck top is not shown) around the screw thread fit vessel port, (screw thread has the suitable structure that the gland after preventing to assemble removes).Other suitable adapting devices (as the buckle pearl) also can be set to be fixed to gland pedestal 224 on the container.In addition in some applications, gland pedestal 224 can disengageably not connect container, perhaps constitutes one with container.

Stretch out traditional seal ring 245 from following the facing down of cover plate 228,, play the tight seal effect to engage the container neck inward flange at vessel port place.

Gland pedestal 224 comprises the escape route 240 that passes cover plate middle body 227 (Figure 11).Gland passage 240 is surrounded by hollow exhaust tube 239.

Preferably utilize hinge means or hinge 252 will cover 250 edges that are hinged to pedestal 224.Lid 250 has the element that damages identification, the element 254 that plate maybe must be removed, and will explain in detail below, covers 250 open and closes so that make.

As first embodiment of the described lid 50 of reference Fig. 1-9, second embodiment of lid 250 limits three pedestals or hole (only seeing in three holes 255 in Figure 11).Each hole 255 is suitable for seating part element 254, covers on 250 in order to element 254 is fixed to, as hereinafter explaining in detail.

As the lid 50 among above-described first embodiment, lid 250 is suitable for rotating between (1) make position (Figure 10,11 and 12) and (2) open position of removing from make position, so that be stored in article in the container by dispensing in the pedestal discharge orifice 240.

Hinge 252 can be any suitable type, comprising the moving class hinge 52 of the card among first embodiment described in Fig. 1-9.The lid 250 of most preferred embodiment and gland main body 224 are to become integrated member by thermoplastic material such as polypropylene or polyethylene molding.Yet cover 250 and main body 224 also can be used as single-piece and form, be preferably designed as and the suitable hinge means that is connected that can the open and close lid becomes inferior piece installing, itself does not constitute a part of the present invention the detail design of hinge and operation.

Lid 250 preferably includes central cover plate 258 (Figure 11 and 12), and has the circumference skirt section of being hung from above by central cover plate 258 peripheries 260.Lid skirt section 260 has the basal surface 262 (Figure 11) that the bottom surface is covered in qualification.When lid 250 closures, as shown in figure 11, skirt section basal surface 262 is suitable for being placed on the circumference anchor ring of pedestal cover plate 228.

Lid 250 also comprises the sealing ring 268 (Figure 11) that is stretched out by central cover plate 258 downwards.Sealing ring 268 is used to surround the also circumferential surface (Figure 11) of sealed engagement gland pedestal escape route pipe 239.This point is specially adapted to liquid container.

Pedestal exhaust tube 239 and lid sealing ring 268 needn't be provided with in above-mentioned mode, and perhaps bending does not need to be provided with.If in fact gland 220 preparations are used for for example little solid matter of material except that liquid, just do not needed liquid-tight seal in some application scenario so.

As the gland of first embodiment among above-mentioned Fig. 1-9, second embodiment of Figure 10-14 expression comprises making and cover 250 and remain on make position, even and remove and still can stop children to open gland (hereinafter will describe in detail) later on damaging recognition component 254.The inserting lock device that inserting lock device that adopts in the gland 220 and the gland among first embodiment 20 adopt is basic identical.

Especially the front portion of gland 220 radially disposes hinge 252 relatively, and pedestal 224 has elastic locking handle 270 (Figure 10,11 and 12), and this lock handle is protruded upward by pedestal cover plate 228 places the position inwards at the pedestal periphery.Lock handle 270 has outward extending ventricumbent shoulder 272.Rear surface 278 is arranged on the handle 270.The top of handle 270 limits crooked far-end 274.Handle 270 also has the anterior convex surface 276 of bevelled that extends downwardly into shoulder 272 from upper distal end 274.

The upper front wall face 282 local apertures that limit by bevelled is flat are inwards arranged on lid central cover plate 258.When lid 250 was swung down to complete make position, wall 282 was as the convex surface that engages handle convex surface 276.When convex wall 282 and handle surface 276 engaged, handle 270 deflected down, and covered 250 and moved to complete make position to adapt to, and at this moment covered skirt section sealing surfaces 262 engaged with base cover plates 228.

The upper limb of lid convex wall 282 terminates in the mortise lock surface 286 (Figure 11) of horizontal arrangement.When lid 250 is located on the make position fully, because the intrinsic elasticity of handle material makes handle 270 turn back to its normal non-inflection point.When lock handle 270 turned back to shown in Figure 11 normal stress free position, unless lock handle 270 at first rotates backward, lock handle shoulder 272 was stacked and placed on and covers on the mortise lock surface 286, and stoped and cover 250 upwards rotations.

Preferably being provided with finger contact recess around handle 270 is beneficial to make adult user that gland is opened.It comprises and Fig. 1-9 shown in the recess of the basic identical shape of recess in the gland lid 50 of first embodiment, wherein this recess partly limits (Fig. 2) by two curved surface 90A and 90B.The shape of covering the circumferential area before the skirt section simultaneously can comprise finger contact surface or indentation (Figure 10), covers 250 so that mention.

Shape, configuration and the orientation on lid 250 and handle 270 surfaces and basic identical with reference to surface configuration, configuration and the orientation of the appropriate section of gland 20 among first embodiment of Fig. 1-9 detailed description.But also can adopt different surfac topographys.In fact, if do not need to consider child safety, damage recognition component gland then of the present invention needn't adopt the shape that prevents that children from opening by mistake.

Be to stop handle 270 initial operations, will damage other element 254 of knowledge and be installed to and cover on 250.Subelement 254 must be torn so that lever 270.Element 254 comprises with fixed part 304 (Figure 14) behind two preceding fixed parts 302 (Figure 14) and and is assembled to the plate 206 that covers on 250.After gone to the part of element 254 was removed, these fixed parts were still stayed on the cover plate 258.Fixed part 302 and 304 is placed in covers in the hole 255.The fixed part 102 of fixed part 302 and 304 structure and first embodiment that describes in detail with reference to Fig. 1-9 is consistent with 104 structure.

Fixed part 302 and 304 connecting panels 206, the damage recognition component 54 corresponding attaching parts structures of attaching parts structure and above-mentioned first embodiment can be consistent with fragile attaching parts.In addition, fixed part 302 and 304 leaves the mode of covering in the hole 255 in can be placed on the mode of covering in the hole 55 with the fixed part 102 and 104 of described first embodiment of reference Fig. 1-9 identical.

The rear portion of damaging recognition component plate 206 withdraws tongue piece 208 (Figure 12 and 14).By firmly mentioning tongue piece 208 element 256 is pulled off from covering 250.Plate 206 is located fracture above still remaining in the fixed part 302 and 304 that covers on 250.

The plate 106 of the front portion of plate 206 and above-mentioned first embodiment anterior different, the front portion of plate 206 does not have mortise lock backplate (the mortise lock backplate 110 of first embodiment as depicted in figs. 1 and 2).In addition, the second embodiment plate 206 comprises downward-sloping tang or tongue piece 380 (Figure 12 and 14).

As shown in figure 14, tongue piece 380 comprises first sloping portion 382 and the second basic vertical component 384.Can find out also that from Figure 12 muscle 386 is protruding by first sloping portion 382.As shown in figure 11, muscle 386 has downward-sloping end face 388 and terminates in basic vertical surface 390 on the ventricumbent basal surface 392 of approximate horizontal configuration.

Tang or tongue piece 380 and muscle 386 are positioned at the back of lock handle 270, prevent that lock handle 270 from moving backward, thereby prevent that also covering 250 opens.Be in the close position and damage recognition component 254 and correctly be contained in when covering on 250 when lid for this reason, tang 380 stretches into downwards in the hole of lock handle 270 back.Muscle 386 provides structure support and rigidity for tongue piece 380.

The shape of tang 380 is suitable for being inserted in lock handle 270 back.Preferably more level and smooth to the transition of tang 380 from the top of damaging recognition component plate 206, and stop owing to attempting the action that levers up that mobile tang 380 produces on the position of lock handle 270 back.

The width of tang 380 is generally less than the width of lock handle 270.Little gap preferably is set, damages that recognition component is mentioned tongue piece 208 and during fragile connecting portion fracture, make and damage recognition component 254 and freely drop from covering with box lunch.

Tang 380 and muscle 386 occupy whole clearance envelopes of lock handle 270 back basically, attempt the motion of mobile tang position so that stop.In addition, any (radially inwards) significantly backward of lock handle 270 move and all to be stoped by muscle 386.But be preferably in a little space is provided between lock handle 270 and the tang 380.Though between the back of lid 250 adjacent part and tang 380, preferably set up the contact of surface to the surface, but be preferably in gap is in a small amount arranged between the rear surface of lock handle 270 and the muscle front surface 390, from fixed part 302 and 304 whens fracture, stop friction force that muscle 386 is remained on its position with convenient plate 206.Therefore if damage recognition component 254 in fixed part 302 and the fracture of 304 places and remove, then attempting to return to original assembled state will can be not successful again.If particularly the element of removing 254 is reinstalled in the initial position, the gap between muscle 386 front portions and lock handle 270 back will stop and set up viscosity and connect so.So when the element 254 of fracture was subjected to minimum mobile, element 254 was easy to separate on its position.This just knows that indicator elment 254 breaks away from advance.

Should be appreciated that if desired, tang 380 can connect mortise lock backplate or side plate 110, is adopted among first embodiment as Fig. 1-9.

Damage identification plate 206 and also preferably include circumference bead 396 and a pair of parallel muscle 398 that separates, this structure has strengthened damaging the rigidity of recognition component.

Be molded as one because element 54 (Fig. 4) or 254 (Figure 14) can separate from gland lid and main body, cover the material different with main body so the material of molded element can adopt with gland.This just allows to use the material that is suitable for forming fragile attaching parts more or contrast colors and/or structure can be provided.

Gland embodiment of the present invention adapts to the alerting ability of product, and it only needs to make the lid and the main body of a band component columns placed hole (as the hole among Fig. 5 55).Do not needing or do not requiring that gland lid and main body can be used in some application that show the infringement element under the situation of not assembling this element.If do not allow this placement hole in the gland of this non-demonstration infringement, cover mold is made do not have the hole just so molded part is simply revised.A kind of adjustable molded assembly, this assembly can adapt to the molded strip placed hole or not with the cap member of placed hole, therefore make to make aspect cost-cutting to have alerting ability.

It will be appreciated that for the gland main body lid and damage recognition component can carry out otherwise modification.For example, available some other the suitable latch mechanism of lock handle (as 70 among Fig. 3) replace, and its operation stops (as 54 among Fig. 1 and 2) effectively by damaging recognition component.Element 54 or 254 shape can not be shapes represented among the figure in addition.Also have, available be less than three fixed parts or element 54 or 254 be fixed to more than three fixed parts cover.The structure of fixed part can change from schematic structure in addition.

From above understanding easily, under the condition of design that does not break away from spirit of the present invention and novelty or principle, can carry out many modifications and modification to detailed introduction of the present invention with illustrating.
