[0069] Figure 16 A to Figure 16 D and Figure 17 A to Figure 17 D have shown the operation of tripping-gear 250 according to an aspect of the present invention.But Figure 16 A shows the diagrammatic sketch of the releasable lock tab 252 that places in the rectangular channel 254 in finished product packing.For ease of discussing, show upper end cover.As discussed above, the top of groove 254 is limited by end cap rim, and the bottom of groove is then limited by the protuberance branch.The left side of groove and the right are by limiting with continuous substantially 256 on surface, the surface of ledge.

[0070] as mentioned above, but releasable lock tab 252 has trapezoidal shape.Therefore, when the side 258 against groove promotes lock tab 252, it will be appreciated that sharp-pointed summit 260 appears on the side 258.Sharp-pointed summit 260 allow lock tabs 252 from the summit 260 point, the side 258 of going up groove 254 that climbs also is raised on the surface 256.Can see that in Figure 17 A to Figure 17 D lock tab 252 is to the motion of surface on 256.

[0071] because cover is flexible and flexible, even thereby when end cap does not have circular peripheral, also can be in the cover opening rotary end cover freely.Rotary end cover causes groove moving with respect to tab.As mentioned above, this moves and causes lock tab to climb to be right after on the surface of groove, to cause lock tab to separate with ledge from groove.In Figure 18 A and Figure 18 B, be shown separating of locking mechanism.In Figure 18 A, each lock tab 252 is arranged in groove 254.In Figure 18 B, after twist-lock lid 262, lock tab 252 no longer is in the groove 254.Can remove end cap this moment.End cap 262 is separated required rotational angle can be regulated by regulating tank 254, lock tab 252 or the size of the two with cover 264.

[0072] might produce one-way release mechanism, in this tripping-gear by only just it being unclamped along a direction rotary end cover.One-way release mechanism for example can realize that this lock tab has first side that has sharp-pointed summit and second side that has square summit by utilizing lock tab.Even if the direction turn-off end cap along square summit is not impossible, will be difficult yet.

[0073] Figure 19 A to Figure 19 D and Figure 20 A to Figure 20 D have shown alternative tripping-gear.According to this aspect of the invention, can use the lock tab 272 of rectangle.As shown in Figure 20 A to Figure 20 D, a side of groove 274 is provided with the inclined-plane 276 that leads to surface 278.When rotary end cover, climb ramp 276 and being raised on the surface 278 of lock tab 272 to separate locking mechanism.In this example, only be provided with an inclined-plane 276.Therefore, locking mechanism has only by 276 direction rotary end cover just can unclamp along the inclined-plane.If desired, second inclined-plane can be added on the opposite side of groove 274, to allow by unclamping locking mechanism along the either direction rotary end cover in the both direction.

[0074] it should be noted, might not break away from spirit of the present invention and use other structure of lock tab and groove.For example, might use more than two lock tabs at each opening.In addition, can use different shapes for end cap with cover.

[0075] Figure 21 to Figure 27 shows the packing of product 300 according to a further aspect of the present invention.In this packing 300, but releasable end cap 302 is arranged on the bottom of cover 304, can not releasable lid 306 be arranged on the top of this cover.End cap 302 is configured as with end cap 306 and holds different products, as holds the bottle of washing lotion or essence.Figure 22 and Figure 23 show the front view and the rearview of packing 300.Figure 24 and Figure 25 show left side view and right side view.Figure 26 and Figure 27 show the top and bottom perspective views of packing 300.

[0076] Figure 28 to Figure 33 shows another packing 350 according to an aspect of the present invention.Figure 28 shows the perspective view of packing 350.As shown in Figure 28, the groove 352 in the end cap 354 is not a rectangle but angled.Figure 29 and Figure 30 show the front view and the rearview of packing.Figure 31 and Figure 32 show left side view and right side view, and Figure 33 shows vertical view.
