Description

Technical Field

[0001] The present invention relates to the technical field of storage boxes, and more particularly to a fresh-keeping film storage box. Background Art

[0002] Currently, the fresh-keeping films sold generally come with paper packaging boxes. The packaging box is a cuboid-shaped box body formed by folding and pasting paper sheets, which is used to store and protect the fresh-keeping film. One side of the paper sheet forming the box body of the packaging box is made into a cover plate. When using it for the first time, the cover plate of the packaging box needs to be torn out first. An outlet is formed between the cover plate and the box body to facilitate pulling out the fresh-keeping film stored in the box body from the outlet to the outside of the packaging box. Generally, a metal sheet densely covered with sharp teeth is fixed at the edge of the cover plate or the outlet, which is used to cut the fresh-keeping film.

[0003] First, after the cover plate is torn relative to the box body, the cover plate cannot be tightly adhered to or fixed to the box body again. The cover plate cannot press and seal the outlet again, and the outlet of the packaging box is often in an exposed state. The fresh-keeping film pulled out to the outlet and the fresh-keeping film still remaining in the box body are both easily contaminated, especially the fresh-keeping film pulled out to the outlet during the previous use. This is a very serious safety hazard for food packaging safety.

[0004] Second, when pulling out the fresh-keeping film from the packaging box, since the weights of the packaging box and the fresh-keeping film are relatively light, while the force required to pull out the fresh-keeping film is relatively large, this will cause the fresh-keeping film to be pulled out smoothly. And the outlet of the packaging box is opened on one side of the top surface of the packaging box. When pulling out the fresh-keeping film from the outlet of the packaging box freely placed on the table, the packaging box is easily pulled and moved, and the packaging box is easily tilted when pulling out the fresh-keeping film. This is extremely inconvenient for most users, and users must hold or grasp the packaging box with one hand.

[0005] However, users must use both hands to pull the left and right sides of the fresh-keeping film respectively to keep the fresh-keeping film pulled out from the outlet in an unfolded film shape. It is impossible to keep the fresh-keeping film pulled out from the outlet in an unfolded film shape well with only one hand.

[0006] Third, since the metal sheet densely covered with sharp teeth fixed on the packaging box is very thin and vulnerable, the sharp teeth are easily skewed, deformed and blunted during use. When cutting the fresh-keeping film, it is necessary to stretch the fresh-keeping film forcefully and make the fresh-keeping film abut against the metal sheet densely covered with sharp teeth, which is rather troublesome. In addition, due to the good stretching performance of the fresh-keeping film, there are often situations where the fresh-keeping film cannot be cut or the cut part of the fresh-keeping film is over-stretched and deformed.

[0007] Fourth, after the cover plate of the packaging box is torn off, the cover plate no longer supports and fixes several side faces adjacent to the surface where the outlet is located, damaging the structural strength of the packaging box. The structure of the packaging box becomes very unstable, and the packaging box deforms when stressed. When the user pulls out the plastic wrap, it is very easy to flatten or squeeze the packaging box. In addition, the paper used to make the packaging box is very thin, and the packaging box made of paper will produce creases, which accelerate the damage of the packaging box. The packaging box is also very easy to get damp and soften. All these factors will cause the packaging box to be damaged when less than half of the plastic wrap in the packaging box is used. Therefore, it is necessary to make improvements. Summary of the Invention

Specific embodiments

[0068] A fresh-keeping film storage box, Figures 1 to 11 As shown, it includes a bottom plate 1, a box shell 2 that can be turned or rotated outward relative to the bottom plate 1, and a cover plate 3 that can be turned or rotated outward relative to the bottom plate 1. The rear side edge of the bottom plate 1 is rotatably connected or integrally connected to the rear side edge of the box shell 2. The box shell 2 movably covers above the bottom plate 1. An outlet 11 for the film is provided between the front side of the box shell 2 and the bottom plate 1. The outlet 11 is arranged at the notch in the lower part of the front side of the top plate box shell 2.

[0069] A storage isolation chamber 12 for storing fresh-keeping film is formed between the box shell 2 and the bottom plate 1. The outlet 11 for the film is arranged at the lower part of the front side of the storage isolation chamber 12. The outlet 11 is adjacent to the bottom plate 1 and communicates with the storage isolation chamber 12. The front side edge of the bottom plate 1 is rotatably connected or integrally connected to the lower side edge of the cover plate 3. The cover plate 3 is equipped with a fresh-keeping film cutting mechanism 4. The cover plate 3 has a folded state and an unfolded state. When the cover plate 3 is in the unfolded state, the upper side edge of the cover plate 3 after being turned outward horizontally supports in front of the outlet 11 for the film. The lower side edge of the cover plate 3 remains connected to the front side edge of the bottom plate 1, forming a fresh-keeping film cutting platform with a fresh-keeping film cutting mechanism 4 arranged in front of the outlet 11 for the film. When the cover plate 3 is in the folded state, the upper side edge of the cover plate 3 is clamped or adhered to the front side of the box shell 2. The cover plate 3 covers or seals the outlet 11 for the film. The cover plate 3 repeatedly opens and seals the outlet 11 for the film. After repeated use, its structural strength will not be damaged or reduced, that is, the structural strength will not be affected, and it can effectively seal the outlet 11 for the film, avoid the fresh-keeping film from being contaminated, and ensure food packaging safety.

[0070] The bottom plate 1, the box shell 2 and the cover plate 3 are integrally formed by an injection molding process and connected together. The main body of the plastic wrap storage box is an integral structure. The main body of the plastic wrap storage box obtained by the injection molding process does not require assembly operations, reducing the assembly operations in the production process, having a lower production cost, and being able to be used repeatedly for a long time, being more environmentally friendly, and solving the problem of large consumption of wood existing in the current configuration of paper boxes for plastic wrap rolls; there is at least one folding connection part 13 integrally formed between the front side edge of the bottom plate 1 and the lower side edge of the cover plate 3; there is at least one folding connection part 13 integrally formed between the rear side edge of the bottom plate 1 and the rear side edge of the box shell 2, so that the box shell 2 and the cover plate 3 can rotate relative to the bottom plate 1 respectively.

[0071] Specifically, the front side edge and the rear side edge of the bottom plate 1 are respectively integrally connected with a folding connection part 13 protruding from the front and rear sides of the bottom plate 1. The folding connection part 13 includes a horizontally extending crease provided in the middle and two connection pieces located on the front and rear sides of the crease; the two connection pieces can rotate forward and backward relative to the crease to enable both the box shell 2 and the cover plate 3 to rotate relative to the bottom plate 1.

[0072] The outer side edges of the two connection pieces of the folding connection part 13 connected between the bottom plate 1 and the cover plate 3 are respectively integrally connected to the front side edge of the bottom plate 1 and the lower side edge of the cover plate 3. When the front side of the box shell 2 is clamped to the upper side of the cover plate 3, the two connection pieces of the folding connection part 13 connected to the front side of the bottom plate 1 are folded and protrude from the front side of the bottom plate 1; the outer side edges of the two connection pieces of the folding connection part 13 connected between the bottom plate 1 and the box shell 2 are respectively integrally connected to the rear side edge of the bottom plate 1 and the rear side edge of the box shell 2. When the box shell 2 is movably covered above the bottom plate 1, the two connection pieces of the folding connection part 13 connected to the rear side of the bottom plate 1 are folded and protrude from the rear side of the bottom plate 1; the thickness of the outer side edge of the connection piece is greater than the thickness of the middle part of the connection piece, and the thickness change trend of the connection piece from the crease to the two outer side edges is gradually increasing, enabling the two connection pieces to rotate relative to the crease easily.

[0073] On the outer side surface of the upper part of the cover plate 3, there is integrally formed an armrest support plate 31 protruding outward and extending horizontally; through the armrest support plate 31, force can be applied well to flip and open the cover plate 3. At the same time, after the cover plate 3 rotates and flattens, the relative position of the armrest support plate 31 relative to the cover plate 3 changes to the armrest support plate 31 being located below the cover plate 3. The armrest support plate 31 serves as a support for the cover plate 3, enabling the cover plate 3 to be well supported and fixed on the front side of the bottom plate 1, and at the same time being used to support the plastic wrap cutting mechanism 4 to cut the plastic wrap.

[0074] The plastic wrap cutting mechanism 4 is arranged inside the upper part of the cover plate 3; at least two hook parts 32 are horizontally spaced inside the inner side of the upper side edge of the cover plate 3, and when the cover plate 3 is in the folded state, each hook part 32 is respectively clamped to the front side edge of the box shell 2; when the cover plate 3 is in the folded state, the plastic wrap cutting mechanism 4 is located inside the box shell 2 or the storage isolation chamber 12; when the cover plate 3 is in the unfolded state, the plastic wrap cutting mechanism 4 flips and moves outside the box shell 2 or the storage isolation chamber 12 along with the cover plate 3, and the plastic wrap cutting mechanism 4 is located above the cover plate 3 in the unfolded state. After rotating and opening the cover plate 3, the front side of the cover plate 3 supports on the tabletop, the top surface of the cover plate 3 is connected to and substantially parallel to the top surface of the bottom plate 1, and the cover plate 3 forms a plastic wrap cutting platform arranged on the front side of the box shell 2. Pull out the plastic wrap from the film outlet 11 to the plastic wrap cutting platform, and directly use the plastic wrap cutting mechanism 4 on the plastic wrap cutting platform to cut the plastic wrap, which is more convenient to use and avoids the plastic wrap behind the plastic wrap cutting mechanism 4 from contacting the tabletop and being contaminated.

[0075] The box shell 2 includes side plates 21 arranged on the left and right sides and a top plate 22. The left and right sides of the top plate 22 are integrally connected to the left and right two side plates 21 respectively, the rear side of the top plate 22 is integrally connected to the bottom plate 1 or the rear side of the top plate 22 is integrally connected to the folding connection part 13 arranged on the bottom plate 1, and the front side of the top plate 22 extends to the top or the front side of the box shell 2. The bottom plate 1 or the side plate 21 is integrally formed with a support piece 14 and a limit piece 15. Specifically, the bottom plate 1 is integrally formed with two support pieces 14 on the left and right. The support pieces 14 protrude on the inner surface of the bottom plate 1, and an arc-shaped support and limit opening for supporting and restricting the rolled plastic wrap is arranged on the upper part of the support piece 14. When pulling out the plastic wrap, the friction force of the plastic wrap rotating is smaller, it is more labor-saving to pull out the plastic wrap, and it avoids the plastic wrap from being over-stretched before being cut; two limit pieces 15 are integrally formed on the left and right sides of the bottom plate 1 respectively. The limit pieces 15 protrude on the inner surface of the bottom plate 1, and the two support pieces 14 are respectively arranged inside the two limit pieces 15. At least the height of the middle part of the limit piece 15 is higher than the height of the middle part of the support piece 14. The left and right positions of the plastic wrap are restricted by the limit piece 15 to avoid the plastic wrap from moving left and right.

[0076] Flip the box shell 2 open towards the rear side, place the plastic wrap made into a roll or a tube on the bottom plate 1, place the plastic wrap at the support and limit opening of the support piece 14, cover the box shell 2 and then buckle the cover plate 3. The plastic wrap is stored in the relatively sealed storage isolation chamber 12. Flip and open the cover plate 3 to pull out the plastic wrap. After use, rotate the cover plate 3 in the reverse direction and make it buckle on the box shell 2. Seal the extra pulled-out plastic wrap in the box shell 2 if any to avoid contaminating the plastic wrap.

[0077] The fresh-keeping film cutting platform makes the fresh-keeping film storage box have a longer width in the pulling direction of the fresh-keeping film. When pulling out the fresh-keeping film, the fresh-keeping film storage box is stably kept stationary on the tabletop. At the same time, suction cups 45 are respectively installed around the bottom of the bottom plate 1. The fresh-keeping film storage box is supported and fixed on the tabletop through the suction cups 45, and the fresh-keeping film storage box is very firmly fixed on the tabletop. When pulling out the fresh-keeping film, the user does not need to fix the fresh-keeping film storage box by hand. The user's both hands can directly hold the left and right sides of the fresh-keeping film. When pulling out the fresh-keeping film, it can be ensured that the pulled-out fresh-keeping film is in a good unfolded and stretched state. After the cover plate 3 is turned over and opened, the position of the film outlet 11 provided at the lower part of the front side of the box shell 2 becomes located at the lower part of the middle of the fresh-keeping film storage box. This also makes the box shell 2 not tilt when pulling out the fresh-keeping film, and it is smoother when pulling out the fresh-keeping film, and each time the length required by the user can be successfully pulled out, avoiding the pulled-out fresh-keeping films from sticking to each other, and at the same time being beneficial for the user to observe and judge the state of the pulled-out fresh-keeping film.

[0078] The box shell 2 is provided with a limit isolation baffle 23. The limit isolation baffle 23 is arranged on the front side of the box shell 2. The upper part of the limit isolation baffle 23 is integrally connected to the top plate 22. The left and right sides of the limit isolation baffle 23 are respectively integrally connected to the left and right side plates 21. An open gap is formed at the lower side of the limit isolation baffle 23. When the box shell 2 is positioned above the bottom plate 1, an open gap between the lower side of the limit isolation baffle 23 and the bottom plate 1 forms a film outlet 11.

[0079] The front side edge of the top plate 22 extends to the front side of the limit isolation baffle 23. A plurality of hook parts 32 are horizontally spaced on the inner side of the upper side edge of the cover plate 3. When the upper side edge of the cover plate 3 is clamped to the front side of the box shell 2, the hook parts 32 are respectively clamped to the front side edge of the top plate 22.

[0080] The front side edge of the top plate 22 extends to the front side of the limit isolation baffle 23. A protruding stop block 26 is integrally formed on the front side edge of the top plate 22; a plurality of hook parts 32 are horizontally spaced on the inner side of the upper side edge of the cover plate 3. When the upper side edge of the cover plate 3 is clamped to the front side of the box shell 2, the upper side edge of the cover plate 3 abuts against the corresponding stop block 26, and the hook parts 32 are respectively clamped to the front side edge of the top plate 22; by the stop block 26 abutting against and positioning the upper side edge of the cover plate 3, the upper side edge of the cover plate 3 and the top plate 22 can be accurately positioned and spliced, and the upper side edge of the cover plate 3 can be fastened to the top plate 22 through the hook parts 32. The stop block 26 and the hook parts 32 are horizontally staggered, and the stop block 26 and the corresponding hook parts 32 are adjacent, so that the upper side edge of the cover plate 3 can be more firmly fastened to the top plate 22 and is not easily displaced, increasing the structural strength and stability. When subjected to an external force, the whole fresh-keeping film storage box is less likely to be deformed, and the cover plate 3 is prevented from being disengaged.

[0081] The upper space of the front side of the storage isolation chamber 12 is enclosed by the limit isolation baffle 23. The front side of the storage isolation chamber 12 is isolated by the limit isolation baffle 23 to form a front storage chamber 16 located within the box shell 2.
