Abstract
Description
Technical Field
[0001] This utility model relates to the field of food packaging bags, and in particular to a hanging bubble bag with biodegradability. Background Technology
[0002] Drip coffee bags, which use a drip extraction method to extract coffee by placing coffee grounds in a container bag, satisfy the requirement of preserving the original flavor of coffee and are convenient to carry. However, most drip coffee bags on the market are made of PE or PP plastic, which are non-biodegradable after use, undoubtedly burdening the environment. Furthermore, to ensure the adhesion between the drip bag and the container bag, EVA or epoxy resin is usually used as an adhesive, which also poses environmental problems during the decomposition of the coffee bag. Utility Model Content
[0003] In order to overcome the above-mentioned defects of the prior art, the purpose of this utility model is to provide a hanging bubble bag with biodegradability, so as to achieve the purpose of the bubble bag being biodegradable and not causing a burden on the ecological environment after use and disposal.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A biodegradable hanging blister pack has a pair of foldable hanging ear components on both sides of the container bag, consisting of connecting hooks and supporting members that connect the connecting hooks to a fixed frame. The hanging ear is composed of cardboard and a starch adhesive layer attached to one side of the cardboard. The container bag is made of filter paper. The back of the fixed frame is heat-fused to the side surface of the container bag. The unit weight of the starch adhesive layer ranges from 3-20 g / m², and the unit weight of the cardboard ranges from 80-300 g / m².
[0006] In a preferred embodiment of this utility model, the unit weight of the container bag ranges from 20 to 100 g / m².
[0007] In a preferred embodiment of the present invention, a connecting frame strip extending toward the center is further provided on the fixed frame, and the supporting members and the connecting hooks connected to each other are placed between the connecting frame strip and the outer frame in sequence to form an integral whole enclosed by the fixed frame.
[0008] In a preferred embodiment of the present invention, the connecting hook has a pair of roots facing each other and connected to the support member, and the roots are provided with flip-fold lines.
[0009] In a preferred embodiment of the present invention, the connecting hook is further provided with a pair of lugs that extend toward the support member facing each other.
[0010] The beneficial effects of this utility model are as follows:
[0011] The present invention provides a biodegradable hanging bubble bag, the bag portion of which is made of filter paper and the ear loop portion is made of cardboard and starch adhesive layer, thereby achieving the purpose of biodegradability of the bubble bag. Attached Figure Description
[0012] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the accompanying drawings used in the description of the embodiments or the prior art will be briefly introduced below.
[0013] Figure 1 This is a plan view of the present invention.
[0014] Figure 2 This is a schematic diagram of the material hierarchy for the ear loops. Detailed Implementation
[0015] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. The above description is for the purpose of simplifying the description of this utility model and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.
[0016] Unless otherwise specified, the singular forms “a,” “the,” and “the” used in this specification include the plural forms. The terms “comprising,” “including,” and “containing” used in this specification indicate the presence of the claimed feature but do not exclude the presence of one or more other features. The term “and / or” used in this specification includes any and all combinations of one or more of the relevant listed items.
[0017] When a component is described in the specification as being "on", "fixed" to, "connected" to, or "joined" to another component, the component may be directly located on, fixed to, connected to, joined to, or in contact with the other component, or there may be an intermediate component present.
[0018] It is understood that although the terms "first," "second," etc., may be used herein to describe different elements, these elements should not be limited by these terms. These terms are merely used to distinguish one element from another. Therefore, a first element may be referred to as a second element without departing from the teachings of this application.
[0019] Exemplary embodiments of this application will now be described with reference to the accompanying drawings. However, it should be understood that this application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide further additional embodiments. Throughout the drawings, the same reference numerals denote the same or functionally identical elements.
[0020] Figure 1 The structure of the coffee bag is shown from one side, including a foldable container bag 100 for holding coffee beans / powder. Folding loops 20 are provided on two opposing sides of the container bag 100. Each loop 20 is primarily composed of an integral connecting hook 21, which connects to a support member 24 between the hook 21 and the fixing frame 25. The outer frame 25b of the fixing frame 25 is located at the outermost periphery of the overall structure, and a connecting frame strip 25a extending inward toward its center is also provided on the fixing frame 25. Both the connecting hook 21 and the support member 24 are located inside the fixing frame 25 and connected by a first dividing line 27. The connecting hook 21 is connected to the support member 24 via a pair of opposing roots 22. The support member 24 is surrounded by the first dividing line 27 and a second dividing line 28, located at the innermost side, for connecting the hook 21 and the connecting frame strip 25a. The back of the fixing frame 25 is bonded to the side surface of the container bag 100. Preferably, the connection method is heat fusion. When in use, pull the connecting hook 21 to make the connecting hook 21 and the support member 24 unfold outward in sequence, so that the connecting hooks 21 on both sides are locked on the edge of the cup and the container bag 100 is fully opened by pulling from both sides.
[0021] Reference Figure 2 The ear loop 20 is made of cardboard 30 coated with a biodegradable starch adhesive layer 40 on one side. Preferably, the basis weight of the cardboard 30 is 80-300 g / m², and the basis weight of the biodegradable starch adhesive layer 40 is 3-20 g / m². The container bag 100 is made of filter paper, preferably with a basis weight of 20-100 g / m².
[0022] In one embodiment of this utility model, since the width of the connection at the root 22 is relatively narrow, a flip fold line 26 is provided to reduce the surface tension at that location, making it easier to fold and prevent breakage.
[0023] In one embodiment of this utility model, a pair of lugs 23 extending toward the support member 24 are provided on the connecting hook 21, so that the user can pull the connecting hook 21 by force through the lugs 23.
