Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Please refer to fig. 1, fig. 2, fig. 3, fig. 4, and fig. 5. The invention relates to a packing box with an adjustable inner cavity volume, which comprises: first curb plate 1, second curb plate 2, by first curb plate 1, the inner chamber that closes formation packing carton is enclosed to second curb plate 2, inner chamber bottom rigid coupling has a receiver 6, receiver 6 part has been accomodate the pulling area 8, sliding through hole 3 has been seted up on the second curb plate 2, pulling area 8 passes through sliding through hole 3 and a pulling piece 5 rigid coupling that sets up in the 2 outsides of second curb plate, be used for can drive when pulling piece 5 slides along sliding through hole 3 and pull and take 8 to stretch out and then change the volume of inner chamber from receiver 6.

The specific use mode of the invention is that the initial state of the packing box is the state shown in figure 2, the pulling block 5 is positioned at the lowest part of the sliding through hole 3, when the number of cigarettes in the packing box is reduced along with the use of a user, the user can push and adjust the pulling block 5 upwards along the sliding through hole 3 according to the number of the remaining cigarettes in the packing box, so that the pulling belt 8 is driven to ascend, the volume of the inner cavity for containing the cigarettes is further reduced, and the purpose that the cigarettes in the packing box are in a close folded state at any time is achieved.

In a preferred embodiment, the accommodating member 6 is provided with an accommodating cavity 12 for partially accommodating the pull belt 8, and one end of the accommodating cavity 12 is in surface communication with the accommodating member 6. This enables the pull strip 8 to be slidably extended or retracted from the port where the receiving cavity 12 communicates with the surface of the receiver 6.

As preferred embodiment, the accommodating part 6 is provided with a limit block 11 at an end port of the accommodating cavity 12 communicated with the surface of the accommodating part 6, and a stop block 10 is fixedly connected to one end of the pulling belt 8 far away from the pulling block 5, so that the limit block 11 blocks the stop block 10. Because the setting of stopper 11 leads to holding the size of chamber 12 and the port department that accomodates 6 surface intercommunication and reducing, and then makes when pulling area 8 stretches out to the longest department, because stopper 11 is to the effect of blockking of backstop piece 10, has guaranteed that pulling area 8 can not break away from in holding chamber 12 completely.

In a preferred embodiment, a support plate 9 is fixed to the pulling strip 8 at one end side near the pulling block 5. The backup pad 9 is in the initial state when not being pulled at pulling area 8, can play a backstop effect of tightening up a cigarette, after pulling area 8 is pulled and rises, backup pad 9 can be driven to the state as shown in figure 3 owing to take 8 rigid couplings with the pulling, because the volume that the rising of pulling area 8 can only make the inner chamber at most is restrainted into a shape of falling the trapezoid, the upper end of cigarette still falls on the contrary easily, backup pad 9 can play the effect of a support to the upper end of cigarette, guaranteed that the cigarette still can be ajusted after the inner chamber volume shrink.

As a preferred embodiment, the length direction of the supporting plate 9 is perpendicular to the length direction of the pulling belt 8, so that the supporting effect is best.

As a preferred embodiment, the container 6 is provided with an auxiliary plate 7 above the portion of the pull tape 8 extending outside the container 6. The auxiliary plate 7 is used for assisting in supporting cigarettes and ensuring that the cigarettes can be stably placed when the pulling belt 8 is in an initial state.

In a preferred embodiment, the auxiliary plate 7 is provided with a fold at the junction with the receptacle 6. The fold allows the auxiliary plate 7 to be easily folded without affecting the movement of the pull strip 8 when the pull strip 8 is raised, as shown in fig. 3.

As a preferred embodiment, a box cover 4 for opening or closing the inner cavity of the packing box is further included.

As the preferred embodiment, a plurality of limiting through holes are uniformly distributed on the sliding through hole 3, and the width of the limiting through holes is smaller than that of the pulling belt 8. The width of spacing through-hole can only slightly be less than the width that pulls area 8 can, can make like this with exerting oneself can be with sliding belt 8 upwards promoting the time guaranteed that sliding belt 8 is difficult to the random activity under the normal condition slightly like this.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
