Description

Technical Field

[0001] The utility model particularly relates to a paste packaging structure and belongs to the technical field of paste packaging. Background Art

[0002] At present, there are some paste-like or viscous chemicals on the market. Most of these chemicals are packed in bottles. These chemicals are inconvenient to use and are easy to cause waste, inaccurate weighing, dripping and other secondary pollution when removing. There are also very few hose packaging on the market. The chemicals packaged in the hose can be squeezed out by squeezing when in use. However, there is a problem with this type of packaging, that is, it cannot be squeezed out cleanly during use, and there are more chemicals remaining in the tube wall. If it is a chemical with high added value or high toxicity, it is very easy to cause waste and pollution to the environment, and the subsequent packaging tube processing will also cause trouble. If the material of the soft packaging is set to a film-like structure, the chemicals inside can be squeezed out more when squeezed, but the film-like structure material is very easy to break when stabbed by external hard objects. It can be seen that the soft packaging bags in the prior art have the problem of internal chemical residues and low utilization rate. Utility Model Content

[0003] The main purpose of the utility model is to provide a paste packaging structure, thereby overcoming the shortcomings of the prior art.

It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as those commonly understood by those skilled in the art to which this application belongs.

[0036] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0037] Example 1

[0038] See also Figure 1 and Figure 2 A paste container includes a container body 100 and a cover body 200, wherein the cover body 200 is arranged on the container body 100 and is used to open and close the discharge port 121 of the container body 100, the container body 100 includes a first shell 110, a second shell 120, a first chamber 101 formed by the first shell 110 and the second shell 120, and a second chamber 102 formed by the second shell 120, at least a part of the second shell 120 is arranged in the first chamber 101, and the second chamber 102 is communicated with the discharge port 121.

[0039] In this embodiment, please refer to Figure 3 and Figure 4 The first shell 110 and the second shell 120 are fixedly connected via a first connection structure 130 that is easily broken. When the first connection structure 130 is broken, the first shell 110 and the second shell 120 are separated, and at least the tail end of the second shell 120 is out of the first chamber 101 and is exposed. Figure 2 The first shell 110 and the second shell 120 are connected only by the first connecting structure 130, and there is no direct connection structure between other parts. Therefore, when the first connecting structure 130 is destroyed, the first shell 110 and the second shell 120 can be separated. When the second shell 120 is exposed, the second shell 120 can be directly squeezed, folded, or curled, so as to make it easier to remove the paste in the container body 100, reduce the residue of the internal paste, and avoid waste.

[0040] It can be understood that the aforementioned first connection structure 130 is easily destroyed, which means that the structural strength of the first connection structure 130, the structural strength of the connection between the first connection structure 130 and the first shell 110, and the structural strength of the connection between the first connection structure 130 and the second shell 120 is less than the structural strength of the first shell 110 and the second shell 120. In this embodiment, the first connection structure 130 is a breakpoint connection structure or an indentation line structure, or the first connection structure 130 is formed by local thinning of the first shell 110 and / or the second shell 120, and the first connection structure 130 can be destroyed by squeezing or using other auxiliary tools. It should be noted that the breakpoint connection structure and indentation line structure used in the utility model are known to those skilled in the art, and no specific limitation or description is made here.

[0041] In this embodiment, the first connection structure 130 is an annular structure continuously arranged along the circumference of the first shell 110. Specifically, an easy-tear film (not shown in the figure) is also arranged on the first shell 110, and the easy-tear film covers the first connection structure 130. Exemplarily, the easy-tear film can be a tape strip, which is adhered to the first shell 110, specifically, adhered to the joint between the first shell 110 and the second shell 120 (i.e., the first connection structure). The tape strip can not only cover the first connection structure and play a certain protective role on it to prevent it from being accidentally damaged, but also play a certain role in connecting the first shell 110 and the second shell 120.

[0042] In this embodiment, the hardness of the first shell 110 is greater than that of the second shell 120, and the second shell 120 is a soft packaging shell. It should be noted that the paste container in this embodiment is used to contain paste, and the paste contained therein can be squeezed out from the discharge port 121 by squeezing the container body 100. Therefore, the first shell 110 and the second shell 120 are both plastic structures, and the shapes of the first shell 110 and the second shell 120 can change under the action of external force, and the paste inside them can be squeezed out. Since the first shell 110 also plays a protective role, the hardness / structural strength of the first shell 110 is greater than the hardness / structural strength of the second shell 120.

[0043] In this embodiment, the first shell 110 and the second shell 120 are plastic components or metal components. For example, the material of the second shell 120 can be PE (polyethylene), PVC (polyvinyl chloride), ETFE (ethylene-tetrafluoroethylene copolymer), etc. The second shell 120 can be folded and curled, so that the paste in the second shell 120 can be squeezed out as much as possible. For example, the material of the first shell 110 can be polyethylene, polypropylene, polyvinyl chloride, cardboard, etc., and the material of the first shell 110 can also be metals such as aluminum and lead. Of course, the first shell 110 can also choose to use cardboard material, which is usually made of hardboard.

[0044] In this embodiment, the thickness of the first shell 110 is greater than the thickness of the second shell 120. The thickness of the first shell 110 is 0.5 mm to 1.5 mm, and the thickness of the second shell 120 is 0.1 mm to 0.3 mm. Specifically, after many experiments, when the thickness of the second shell 120 is 0.1 mm to 0.3 mm, it is easier to fold and curl for internal chemical extrusion, and the weight of the residual chemical in the second shell 120 will not exceed 0.3% of the total capacity, which is very suitable for loading quantitative pastes.

[0045] In this embodiment, the paste packaging structure also includes an extrusion ring, which is sleeved on the tail end of the second shell. The extrusion ring is located in the first chamber 101, and the extrusion ring is movably cooperated with the first shell 110 and the second shell 120. Specifically, the extrusion ring has a slit, and the tail end of the second shell is arranged in the slit. By moving the extrusion ring along the axial direction of the container body 100, the second shell can be squeezed from the bottom, thereby making it easier to squeeze out all the paste inside the second shell, further avoiding the residue of the paste.

[0046] Example 2

[0047] See also Figure 5 The structure of a paste container in this embodiment is basically the same as that in Embodiment 1, and the same parts of the two will not be repeated here. The difference between the two lies mainly in that the first connecting structure 130 in Embodiment 1 is a smooth linear structure, while the first connecting structure 130 in this embodiment is a serrated structure. The serrated structure of the first connecting structure 130 is more easily damaged, thereby reducing the difficulty of separating the first shell 110 and the second shell 120.

[0048] Example 3

[0049] See also Figure 6 and Figure 7The structure of a paste container in this embodiment is basically the same as that in Embodiment 1, and the same parts of the two will not be repeated here.

[0050] In this embodiment, the first shell 110 includes at least two main parts 111, and the at least two main parts 111 are fixedly connected via an easily destructible second connecting structure 140. When the second connecting structure 140 is destroyed, at least one main part 111 of the first shell 110 is removed, and a window exposing the rear end of the second shell 120 is formed on the first shell 110, or the main part 111 of the first shell 110 can be folded to form a window exposing the rear end of the second shell 120, through which the second shell 120 can be folded, curled, etc., and the extrusion ring on the second shell 120 is also exposed at the window.

[0051] In this embodiment, the aforementioned second connecting structure 140 is easily destructible, which means that the structural strength of the second connecting structure 140 and the structural strength of at least one of the connections between the second connecting structure 140 and the main part of the first shell 110 are smaller than the structural strength of the main part of the first shell 110.

[0052] In this embodiment, three second connecting structures 140 are provided on the first shell 110, and the three second connecting structures 140 are connected to form an “I” shaped structure, wherein at least one second connecting structure 140 is arranged at a part close to the rear end of the second shell 120 and parallel to the rear end of the second shell 120.

[0053] In this embodiment, the second connection structure 140 is a smooth linear structure or a serrated structure. More specifically, the second connection structure 140 is a breakpoint connection structure or an indentation line structure, or the second connection structure 140 is formed by local thinning of the first shell 110 .

[0054] Example 4

[0055] See also Figure 8 and Fig. 9 The structure of a paste container in this embodiment is basically the same as that in Embodiment 1, and the identical parts thereof will not be described in detail here. In this embodiment, a second connecting structure 140 is provided on the first shell 110, and the second connecting structure 140 is a ring structure.

[0056] The connection structure between the first shell and the second shell of a paste container provided by an embodiment of the utility model can be destroyed, or the structure of the first shell itself can be destroyed, so that the second shell with lower hardness and softer is exposed, so that the paste in the second shell can be fully squeezed out by folding / curling, etc., thereby reducing the residue of the paste.
