Technical Field

[0001] The invention relates to the field of tableware, in particular to a disposable aluminum foil lunch box. Background Art

[0002] In daily life, the convenience of using disposable lunch boxes has led to an increasing demand and usage of disposable aluminum foil lunch boxes. Existing disposable lunch boxes can be heated by gas stoves to maintain the temperature of the food in the lunch box and improve the user's dining experience. However, in outdoor sports, users need to carry a special alcohol stove or cassette stove with a bracket to heat the lunch box, which increases the burden of carrying.

[0003] In response to this technical problem, a variety of disposable lunch boxes with simple brackets have appeared on the market. The brackets can be used to lift the lunch boxes off the ground, and a simple alcohol stove can be placed at the bottom of the lunch boxes to complete the heating. However, such lunch boxes are not easy to stack due to the brackets, and they take up a lot of space, which greatly increases their transportation costs. Summary of the invention

[0004] The present invention aims to provide a disposable aluminum foil lunch box, which can be suitable for more places such as outdoors and is easy to carry and transport.

[0005] In order to solve the above technical problems, the specific solution adopted by the present invention is a disposable aluminum foil lunch box: it includes a lunch box body, a flange arranged along the open mouth of the lunch box body and ears symmetrically arranged on the flange, and its characteristics are: an arc-shaped bendable support strip is arranged on the ears, one end of the bendable support strip is hingedly connected to the ear, the other end of the bendable support strip is in contact with the lower edge of the flange and extends to the bottom of the other ear and is provided with an ear-shaped palm plate, the position of the bendable support strip near the end of the ear forms an upper bending portion, and the connection between the bendable support strip and the ear-shaped palm plate forms a lower bending portion.

[0006] As a further optimization of the disposable aluminum foil lunch box of the present invention: the bendable support strip is made of a rigid material.

[0007] As a further optimization of the disposable aluminum foil lunch box of the present invention: an upper engraved line for facilitating the bending of the bendable support strip is provided at the upper bending portion, and a lower engraved line for facilitating the bending of the ear-shaped palm plate is provided at the lower bending portion.

[0008] As a further optimization of the disposable aluminum foil lunch box of the present invention: an auxiliary palm plate is stacked on the ear-shaped palm plate, and a center score line for folding the auxiliary palm plate is provided between the auxiliary palm plate and the ear-shaped palm plate.

[0011] As a further optimization of the disposable aluminum foil lunch box of the present invention: a pin is welded on the bendable support strip, a round hole for the rotational cooperation of the pin is opened on the ear, the upper end of the pin passes through the round hole and is provided with an upper baffle for preventing the bendable support strip from falling.

[0012] Beneficial Effects

[0013] The present invention discloses a disposable aluminum foil lunch box, comprising a lunch box body, a flange arranged at an open portion of the lunch box body, and a support ear symmetrically arranged on the flange. A bendable support strip is hinged on the support ear, one end of the bendable support strip is hinged to the support ear, and the other end extends to the lower side of the opposite support ear along the direction of the flange and is provided with an ear-shaped palm plate having the same shape as the support ear. During outdoor use, two bendable support strips can be respectively released from the flange and the support ear by rotating and bending twice to form a stable support mechanism, and the lunch box body is lifted to a certain height from the ground by the support mechanism, so that the lunch box body can be heated by a simple alcohol stove or the like, thereby reducing the burden of carrying complex stoves such as cassette stoves by users.

[0014] The bendable support strips in the present invention are closely attached to the flange and the ear in the initial state, and do not significantly increase the occupied space of the lunch box body. They can still be stacked like conventional lunch boxes without a stand, without additionally increasing the transportation cost, and have higher promotion value. In a preferred embodiment of the present invention, an auxiliary palm plate is also stacked on the ear-shaped palm plate used to support the ground or the tabletop. During use, the auxiliary palm plate can be extended to significantly increase the contact area with the ground or the tabletop, further increasing the stability of the structure. In addition, the auxiliary palm plate is moved and stacked on the lower edge of the ear together with the ear-shaped palm plate in the initial state, and does not increase the occupied space of the present invention.

[0015] The bendable support strip in the present invention is arc-shaped. After being rotated and bent to form a support mechanism, on the one hand, the arc center directions of the two bendable support strips are staggered, thereby making the support mechanism structure stable; on the other hand, the arc-shaped structure of the bendable support strip itself can also be used to produce a certain buffering effect, so that after the lunch box body is impacted by the outside world, the impact force is absorbed through the bending deformation and recovery process of the bendable support strip, thereby avoiding the lunch box body from tilting, further improving its stability in supporting the lunch box body, and being particularly suitable for use in places such as moving vehicles.

[0024] The main structure of the present invention is similar to the disposable aluminum foil lunch box in the prior art, and both include a lunch box body 7, a flange 6 arranged at the open end of the lunch box body 7, and a support ear 4 symmetrically arranged on the flange 6. The difference between the present invention and the prior art is that the present invention has a hidden and distributed bendable support strip 3, which does not increase the carrying burden of the user and the transportation cost of the enterprise, and can be heated only by a simple alcohol stove, which is particularly suitable for outdoor use.

[0025] like Figure 1 and Figure 2 As shown in the figure, the present invention is provided with a bendable support bar 3 on each of the two ears 4. One end of the bendable support bar 3 is hinged to the corresponding ear 4, and the other end extends along the contour of the lower edge of the flange 6 to the lower part of the other ear 4 and is provided with an ear-shaped palm plate 1 corresponding to the shape of the ear 4. The bendable support bar 3 can rotate around the hinge point under the action of external force to achieve the following Figure 2 The storage status shown and Figure 3 Shown in the pulled-out position. Figure 2 Large quantities of stacking and transportation are carried out in the state shown. Figure 3 In the pulled-out state shown, the two bendable support strips 3 form a stable support structure through a simple bending operation.

[0026] Each bendable support bar 3 of the present invention has two bends, one of which is an upper bend close to the ear 4, and the other is a lower bend close to the ear-shaped palm plate 1. In order to facilitate the bending operation of the bendable support bar 3, the bends are combined with the upper bends of the upper bends. Figure 1 and Figure 3 As shown, the present invention further provides an upper engraved line 8 and a lower engraved line 2 on the upper bending portion and the lower bending portion respectively.

[0027] Through the above technical scheme, the specific implementation process of the present invention is as follows:

[0028] During the conveying process, the two bendable support strips 3 are rotated to Figure 2 Status shown;

[0029] During outdoor implementation, the user pulls out the two bendable support strips 3 to the Figure 1 After that, the two bendable support bars 3 are bent into the following shapes through the upper engraved line 8 and the lower engraved line 2. Figure 3 and Figure 4 At this time, the arc center directions of the two bendable support bars 3 are staggered, and the two ear-shaped palm plates 1 are staggered, forming a stable support mechanism for supporting the lunch box body 7. The user can place the simple alcohol stove directly under the lunch box body 7, on the ground and between the two bendable support bars 3, to achieve heating of the food in the lunch box body 7.

[0030] The following three embodiments further describe the local details of the present invention in detail:

[0031] Example 1

[0032] Combination Figure 3 and Figure 5 As shown, in this embodiment, corresponding circular holes are provided on the support ears 4 and the ear-shaped palm plate 1, and a rotatable pin shaft 10 is inserted into the circular hole. The hinged connection between the bendable support bar 3 and the support ears 4 is realized by the rotational cooperation between the pin shaft 10 and the two circular holes, so that the support ears 3 can be flexibly rotated around the pin shaft 10 under the action of external force, thereby facilitating the switching of the storage state and the pull-out state. The upper and lower ends of the pin shaft 10 are respectively fixed with an upper baffle 5 and a lower baffle 11 to prevent the pin shaft 10 from falling out of the circular hole.

[0033] Example 2

[0034] Combination Figure 3 and Figure 6 As shown, a pin shaft 10 is welded and fixed on the bendable support bar 3, and the upper end of the pin shaft 10 passes through a circular hole provided on the support ear 4 and is fixed with an upper baffle 5. The upper baffle 5 prevents the integral structure consisting of the pin shaft 10 and the bendable support bar 3 from falling off the support ear 4.

[0035] Example 3

[0036] like Figure 7 As shown, in this embodiment, an auxiliary palm plate 12 is stacked on the ear-shaped palm plate 1, and the shape of the auxiliary palm plate 12 is consistent with that of the ear-shaped palm plate 1. A middle score line 9 is provided between the auxiliary palm plate 12 and the ear-shaped palm plate 1 to facilitate the folding of the auxiliary palm plate 12. When the embodiment is not in use, the auxiliary palm plate 12 is stacked on the ear-shaped palm plate 1 along the middle score line 9; and when the embodiment is in use, the auxiliary palm plate 12 is folded along the middle score line 9 to contact the ground together with the ear-shaped palm plate 1, greatly improving the stability of the support.
