Description

The safety-type Bottle cap with straw

Technical field the utility model relates to a kind of packing container, specifically relates to a kind of the have beverage bottle that seals film and used suction pipe.

A lot of beverage product to be arranged in order extending the shelf life on the background technology market, to adopt the mode of sealing film at bottleneck, give one again as an addition with beverage during sale and can pierce through the suction pipe that seals film.This hand-held suction pipe pierces through the way of sealing film, and is both unhygienic, also inconvenient.

The summary of the invention the purpose of this utility model is to propose a kind of Bottle cap with straw, and suction pipe is combined with bottle by bottle cap, and rotation suction pipe during unlatching can pierce through the film that seals of bottleneck and realize opening; By enlargement technology, make its structure more rationally, reliably, meet the standard of safety, health more.Concrete scheme comprises having the bottleneck that seals film and can pierce through the suction pipe that seals film, is connected with Ji Gai on the bottleneck, and suction pipe covers and be passed down through Ji Gai by thread connection in base.

Using the commodity that seal the film packing in the reality mainly is beverages such as children really suckle, AD calcium milk at present, and its main consumer group is children.In the technique scheme, its suction pipe is limit often do shorter and smaller because of structure, and spininess is made in the lower end of suction pipe, and its suction pipe can be spun off again at any time before and after opening.When children suck beverage, suction pipe need be kept in the mouth, if suction pipe is gulped down by children's mistake, consequence will be very serious.According to national relevant laws and regulations, the packing of food should meet the requirement that ensures consumer safety, and particularly at children market colony, above-mentioned potential safety hazard must be eliminated.Can adopt following technical scheme:

Scheme one is to have to prevent that suction pipe from rotating up the anti-reverse ratchet that breaks away from Ji Gai between suction pipe and base lid.Anti-form and position of reversing ratchet can be provided with flexibly, can above the suction pipe screw thread, below or other position, the technical scheme of specializing is, suction pipe is made of outer suction pipe and the inner suction pipe that top links to each other, base covers to have between upwardly extending support tube described outer suction pipe of insertion and the inner suction pipe, and described anti-reverse ratchet and screw thread are between support tube and suction pipe.Specifically, anti-reverse ratchet and screw thread can be separately positioned on the outer wall or inwall of support tube, also can be arranged on simultaneously on the outer wall or inwall of support tube, another part of ratchet and screw thread then relative set on outer suction pipe or inner suction pipe.Anti-reverse ratchet engagement in a single day between suction pipe and base lid just again can not be thrown off, and is very reliable.

Scheme two is that suction pipe is made of outer suction pipe and the inner suction pipe that top links to each other, base covers to have between upwardly extending support tube described outer suction pipe of insertion and the inner suction pipe, have screw thread between suction pipe and the support tube, also have between the two and prevent that suction pipe upwards breaks away from the annular snap close of Ji Gai.Described annular snap close can be a convex hoop shape, can be the double wedge of annular spread also, is generally being separately positioned on two parts that match, being meshing with each other the effect that limits the position of playing.In such scheme, of smashing of a pair of ring lock that can replace by the screw thread of suction pipe or support tube matching.Because above-mentioned suction pipe is a double-decker, makes the position of annular snap close be provided with very big alerting ability.Its position can not be arranged at described screw thread and ring lock deduction of points on the outer wall or inwall of support tube above or below screw thread yet, and the another part that matches then is arranged on outer suction pipe or the inner suction pipe.

Above-mentioned two technical schemes are simple and reliable, solved the problem that aforesaid suction pipe can be spun off with less improvement, have advantage easy to implement.The plastics manufacturing preferably of the described the most handy elasticity of each part, the elasticity of its material has been created condition for the demoulding, the cooperation of each parts.

For ensureing the health of suction pipe, be preferably in the outer protecting cover of socket of suction pipe.But only so not enough, when beverage was for sale on shelf, its protecting cover can be taken off by the people at any time and play with, might be contaminated, and this also is a potential safety hazard.Commodity its packing before selling should be the state that can not open, and the work of unlatching can only be finished by the customer, so be necessary to set up lockout mechanism between protecting cover and suction pipe.Scheme is as follows, and suction pipe is socketed with protecting cover outward, has anti-rotation ribs between the two and has the annular snap close that prevents that protecting cover from upwards being pulled out, and when protecting cover drives suction pipe and is rotated down, makes described annular snap close force to throw off by Ji Gai to the antagonistic force of protecting cover.That is to say, utilize the elasticity of protecting cover, keep connecting by annular snap close between protecting cover and the suction pipe, when directly upwards pulling out protecting cover, can compare difficulty with hand, but when suction pipe rotates when downward by the effect of screw thread, because of the strength of screw thread will be far longer than the strength of finger, can make above-mentioned annular snap close force to throw off.

Also can between protecting cover and base lid, install lockout mechanism additional, described suction pipe is made of outer suction pipe and the inner suction pipe that top links to each other, base covers to have between upwardly extending support tube described outer suction pipe of insertion and the inner suction pipe, has screw thread between suction pipe and the support tube, suction pipe has protecting cover outward, has anti-rotation ribs between the two, has the annular snap close that prevents that protecting cover from upwards being pulled up between protecting cover and the support tube, when suction pipe rotates when downward, the crowded support effect by outer suction pipe lower edge is thrown off described annular snap close.The advantage of this scheme is that cooperation is reliable, only needs during assembling protecting cover, suction pipe, base lid three are overlapped in order to plug and get final product, and does not require that the screw thread between suction pipe and the support tube must screw, and can simplify assembling procedure.Described anti-rotation ribs can be arranged on the lateral wall of suction pipe, also can be arranged on the inner hole wall of suction pipe, is generally around the fin or the polygon column that distribute.

Another kind of scheme is to set up to have destructive antitheft opening mechanism on protecting cover, opens the back and form tangible depredation on protecting cover, guarantees that it can only open once.Specifically scheme is, has protecting cover outside suction pipe, and protecting cover is connected with Ji Gai by the point of connection that can rupture.Concrete connection mode can make described point of connection and protecting cover and base lid one-body molded; Also available other alternative the snap ring that can firmly connect with Ji Gai for example is set, and this snap ring and protecting cover and point of connection is one-body molded.

Connecting mode between Ji Gai and the bottleneck is generally thread connection, but can be spun off at any time like this.Only do so intentionally, in general Ji Gai just there is no need to take off since being installed on the bottleneck again, if basic lid can be spun off, can make the customer not know how this opens and seal film.Simultaneously, based on the consideration of the safety identical, health aspect, be necessary also to prevent that Ji Gai from being taken down with the front.Specifically scheme is, links by screw thread between Ji Gai and the bottleneck, also has between the two to prevent that Ji Gai from rotating up the anti-reverse ratchet that breaks away from bottleneck.Described anti-reverse ratchet can be arranged on screw thread above or below.So, after bottle cap screws on bottleneck, again can not be spun off.

Adopt thread connection between Ji Gai and the bottleneck, need assemble, also have another kind of easier, more firm connection scheme, promptly link by annular snap close between Ji Gai and the bottleneck with the mode of rotation.Specifically can cover the protruding tooth that inwall is provided with a bulge loop or distributes ringwise at base, and at the bottleneck outer wall corresponding grooves is set, after basic cap seal was loaded onto bottleneck, the two was meshing with each other and prevents that Ji Gai from being taken down.Rotate if will prevent Ji Gai, the anti-rotation ribs of annular spread can also be set between Ji Gai and bottleneck, its position can be located at the below or the top of above-mentioned annular snap close, and is perhaps interlaced with the protruding tooth shape snap close that distributes ringwise noted earlier.This scheme has the simplification mould, encapsulates advantage efficiently, only needs during encapsulation to pressing down Ji Gai just, and is very simple, is applicable to little amount can operation, is more suitable in high-speed canning manufacturing line in enormous quantities.

According to different operatings needs, above-mentioned every technical scheme about suction pipe, protecting cover and Ji Gai can be on same bottle cap applied in any combination, concrete assembled scheme can have multiple variation.

The specific embodiment

Embodiment one, (referring to Fig. 1, Fig. 2, Fig. 3) suction pipe 4 is made of outer suction pipe and the inner suction pipe that top links to each other, there is spine the inner suction pipe lower end, having upwardly extending support tube 30 on the base lid 3 inserts between described outer suction pipe and the inner suction pipe, has the screw thread 41 that matches between support tube 30 and the inner suction pipe, have the anti-reverse ratchet 42 that matches between support tube 30 and the outer suction pipe, its rotation direction is consistent with the backspin rotation direction of screw thread 41.Base lid 3 anti-rotation ribs 34 by annular snap close 33 and annular spread firmly are connected on the bottleneck 2, can not be taken down.

Suction pipe 4 overcoats are inserted with protecting cover 5, protecting cover 5 inwalls and the outer suction pipe outer wall of suction pipe 4 have the anti-rotation ribs 54 of the annular spread that matches, protecting cover 5 inwalls also have twice annular snap close 53 up and down simultaneously, the lower edge that is anti-rotation ribs 54 with the outer suction pipe lower edge of suction pipe 4 is meshed, to prevent that protecting cover 5 from being pulled out easily.This moment, the outer suction pipe lower edge of suction pipe 4 also was simultaneously the mating part of protecting cover 5 inwalls annular snap close 53.Protecting cover 5 drives suction pipe 4 rotations during unlatching, and because of the anti-effect that reverses ratchet 42, suction pipe 4 can only be rotated down and can not rotate up.Effect by screw thread 41, suction pipe 4 is the support constraint of taking off protecting cover 5 inwalls annular snap close 53 by force downwards, downwards the spine of suction pipe 4 penetrate bottleneck seal film 1, and then suction pipe 4 again by force support take off second road annular snap close of protecting cover 5 inwalls, can pull out protecting cover 5, realize opening.4 in suction pipe is retained on the base lid 3 and can not takes down.

The advantage of present embodiment bottle cap is, mould is simple, and cost is low.During assembling, utilize the elasticity of plastic earlier suction pipe 4 to be pressed fit in the protecting cover 5, the two is fitted in together on the support tube 30 of base lid 3 again, the screw thread 41 between suction pipe 4 and the support tube 30 is forced to press down engagement.Encapsulation between last bottle cap and the bottleneck 2 only needs bottle cap is withheld on bottleneck, gets final product saving of work and time to next pressure.

Embodiment two, and (referring to Fig. 4, Fig. 5, Fig. 6) compares with embodiment one, and its difference is, anti-rotation ribs 54 between protecting cover 5 and the suction pipe 4 adopts other form, promptly extends downwards from protecting cover 5 roofs, stretch in the endoporus 40 of suction pipe 4, the fitting surface between the two is a multi-edge column-shaped.The advantage of this structure is that the outward appearance of suction pipe 4 is relatively slicker and more sly.

Support tube 30 bottoms at base lid 3 have a pair of outwardly directed elastic lock 582 around symmetry, match with protecting cover 5 inwall bottom corresponding annular snap closes 58, to prevent that protecting cover 5 from being pulled out.Screw thread 41 between the outer suction pipe of support tube 30 and suction pipe 4, the top position of elastic lock 582.The screw thread 41 of support tube 30 and elastic lock 582 can adopt side somatotype mould molding.Rotation protecting cover 5 during unlatching drives suction pipe 4 rotations by its anti-rotation ribs of extending 54 downwards.As shown in Figure 4, this moment, suction pipe 4 just contacted with screw thread 41 ends between the support tube 30, as if backwards rotation, then the phenomenon that dallies can occur; If forward rotation, then the outer suction pipe lower edge of suction pipe 4 squeezes gradually downwards and struts the snap close 58 (582) that matches between support tube 30 and the protecting cover 5, realizes unlatching.

For unlatching back suction pipe 4 is not taken down, suction pipe inwall bottom is provided with annular snap close 43 together outside, and when suction pipe rotated to the bottom, described snap close 43 can be meshed with the elastic lock 582 of support tube 30 bottoms.This moment, suction pipe 4 just separated with screw thread 41 tail ends between the support tube 30, lost engagement force, no matter be forward or backwards rotation suction pipe 4, all the phenomenon that dallies can occur.

The advantage of present embodiment bottle cap is that protecting cover 5 lockings are reliable, and rotation easily.

Embodiment three, and (referring to Fig. 7, Fig. 8, Fig. 9) compares with embodiment one, two, and its main difference point is, has set up anti-pirate of the open function on bottle cap, and its protecting cover 5 is one-body molded with base lid 3, and is continuous by several point of connection that can rupture 55 of annular spread.Because of mould structure is limit, the support tube 30 of base lid 3 needs independently to make.As Fig. 7, shown in Figure 9, support tube 30 bottoms are circular underframe, cover 3 main bodys by the anti-rotation ribs 39 of annular snap close 38 and annular spread with base and are fixedly connected.Because support tube 30 covers 3 main body mortise with base all the time, plays a role jointly, still being considered as is the part of base lid 3.Base lid 3 links with bottleneck 2 by annular snap close 33, has the anti-rotation ribs 34 of the annular spread that matches above annular snap close 33.The anti-rotation ribs that is positioned on the bottleneck 2 is protruding slightly a bit just, and film 1 is very thin owing to sealing, and can not influence anti-rotation ribs 34 and play a role.

Have the screw thread 41 that matches between support tube 30 and the suction pipe 4, the outwardly directed elastic lock 582 that support tube 30 bottoms have several annular spread is meshed with the annular snap close 58 of protecting cover 5 inwall bottoms.Compare with embodiment two, the stripping means of elastic lock 582 is not quite alike, can use the mould structure of side somatotype.Have the anti-ratchet 42 that reverses in the outer suction pipe inwall bottom of suction pipe 4, the elastic lock 582 overhanging with support tube 30 matches, and its rotation direction is consistent with the backspin rotation direction of suction pipe 4.Such structure makes protecting cover 5 and suction pipe 4 can just change like a cork or reverse at the rotation initial stage, when suction pipe be threaded to for 4 times pierce through seal film 1 after, just can not upwards reverse again.Elastic lock 582 in the present embodiment uses as the anti-ratchet that reverses simultaneously, and special-purpose ratchet or ratchet also can be set in support tube 30 relevant positions when specifically implementing.

Can also adopt other lock mode between suction pipe 4 and the support tube 30, as annular snap close is set between the two.As shown in Figure 7, suppose the anti-reverse ratchet 42 of cancellation suction pipe 4, the annular snap close 43 of projection is set on the inner suction pipe external diameter of suction pipe 4, its diameter is greater than the path of support tube 30 inner threads 41.Make described annular snap close 43 be snapped in the below of support tube inwall spiral shell by pressure bursts during assembling, thereby after preventing that bottle cap unlatching protecting cover 5 from being taken down, suction pipe 4 is rotated up to take down.

In sum, because of the utility model that length is limit embodies a concentrated expression of numerous technical characterictics among above-mentioned three embodiment, array mode between each technical characterictic not necessarily can reach perfect condition, during practical application, can accept or reject, simplify and reconfigure the technical characterictic that is occurred according to different demands.
