Description

Technical Field

[0001] The utility model belongs to the technical field of packaging bags, in particular to an easy-to-tear center-sealed bag for tea. Background Art

[0002] The tea packaging bag is a middle-sealed bag structure, which is composed of a bottom, front and rear end faces and two side walls. Both side walls have fold lines folded inward along the length direction, and the front and rear end faces are connected at one end away from the bottom to form a closed storage chamber.

[0003] In order to facilitate users to tear open the packaging bag, a U-shaped or V-shaped notch is usually opened on one side of the bag opening, such as Figure 1 As shown, the user only needs to pinch the two sides of the notch and apply an external force to drive the two sides of the notch to move relative to each other, so as to tear open the package; however, since the bag body of the middle-sealed bag is generally composed of an outer paper part and an inner sealing film part, when the user tears open the bag body, it is necessary to tear open the four-layer structure consisting of two layers of paper and two layers of sealing film at the same time, which is difficult to tear open, and the trajectory of the bag opening after tearing is irregular. Utility Model Content

[0004] The utility model aims at solving the problems of the prior art and provides an easy-tear middle-sealed bag for tea. The specific technical solution is as follows:

[0005] The invention discloses an easy-tear center-sealed bag for tea, comprising a bag body and a tearing structure arranged on any end surface of the bag body, wherein the tearing structure comprises a bag opening opened along the width direction of the bag body, and a tearing strip is connected in the bag opening through a serrated line to form a closure for the bag opening.

[0006] As a further technical solution of the present invention, one end of the tear strip is connected to a tear tongue, and a pre-buried groove corresponding to the tear tongue is opened on the bag body, and the pre-buried groove is connected to the bag opening.

[0007] As a further technical solution of the present invention, a curtain for blocking the tearing structure is arranged on the bag body, and the connecting end of the curtain is connected to the bag body along the width direction of the bag body. The free end of the curtain naturally hangs down due to the interference of gravity and forms a shield for the tearing structure.

[0008] As a further technical solution of the present invention, a seal is provided in the bag body, and the seal is provided below the bag opening; the seal is composed of two sealing strips that can be buckled with each other, and the two sealing strips are respectively provided in the two end walls of the bag body. When the two sealing strips are buckled with each other, the internal space of the bag body can be divided into two parts that are not connected to each other.

[0009] As a further technical solution of the present invention, a tear section is formed on the end surface of the bag body having the tear structure, extending upward along the seal to the top of the bag body, and the tear section is a single-layer structure.

[0010] The beneficial effects of the utility model are as follows:

[0011] (1) In the present application, a tearing structure is arranged on one end surface of the bag body. When opening the bag, only a double-layer structure of a layer of paper and a layer of sealing film needs to be torn off, thereby reducing the difficulty of opening the bag. At the same time, the setting of the serrated line can guide the tearing direction of the tear strip, so that the trajectory of the bag opening after tearing is smooth and regular.

[0012] (2) In the present application, a seal is provided in the bag body to separate the bag body into two mutually unconnected chambers, and the portion above the seal in the end face with the tear structure is provided with a single-layer structure, thereby further reducing the difficulty of tearing the tear strip while ensuring the sealing effect.

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0020] The present application aims at the bag structure of the prior art which needs to tear open four layers at one time. By setting a tearing structure on any end surface of the bag body, the user can open the bag opening through the tearing structure. Since the tearing structure is set on one end surface, the user only needs to tear open the double-layer structure of a layer of paper and a layer of sealing film to open the bag opening, and the difficulty of tearing open the bag opening is low.

[0021] Figure 2 The overall structure schematic diagram of the easy-tear middle seal bag for tea is shown; Figure 2The easy-tear middle seal bag for tea comprises a bag body 100 and a tearing structure arranged on any end surface of the bag body 100, that is, the bag body 100 has two end surfaces, front and back, and the tearing structure can be arranged on one of the end surfaces; the tearing structure comprises a bag opening 210 opened along the width direction of the bag body, and a tearing strip 220 is connected to the bag opening 210 through a serrated line to form a closure of the bag opening 210; the tearing strip 220 is inside the bag opening 210, and the two are connected by a serrated line, so that the user can easily The bag opening 210 is opened by tearing off the tear strip 220, and the serrated lines can be formed by laser or heat pressing. When the user tears off the tear strip 220, he only needs to tear off the double-layer structure of a layer of paper and a layer of sealing film, and the difficulty of opening the bag opening 210 is small. The setting of the serrated lines can guide the tearing direction of the tear strip 220, so that the trajectory of the bag opening 210 after tearing is regular, which is convenient for pouring out the tea leaves in the bag body 100 later; one end of the tear strip 220 is connected to the tear tongue 230, and the bag body 100 is provided with a tear tongue 230. The pre-buried groove 240 corresponding to the tearing tongue 230 is provided, and the pre-buried groove 240 is connected to the bag opening 210; the tearing tongue 230 can be hidden in the pre-buried groove 240, and the tearing tongue 230 is pushed out from the back of the bag body 100 to make the tearing tongue 230 separate from the pre-buried groove 240. The tearing tongue 230 is pinched and an external force is applied to tear off the tear strip 220, and the bag opening 210 is opened. The setting of the tearing tongue 230 provides an edge portion for the user to tear the tear strip 220 for easy force application; the bag body 100 A barrier curtain 250 for blocking the tearing structure is provided on the bag body 100, and the connecting end of the barrier curtain 250 is connected to the bag body 100 along the width direction of the bag body 100. The free end of the barrier curtain 250 naturally hangs down due to the interference of gravity and forms a barrier for the tearing structure. The barrier curtain 250 is arranged above the tearing structure, and when the free end hangs down naturally, it can block the tearing structure so that it is not exposed under normal circumstances, thereby preventing the bag mouth 210 from opening during transportation or sales. When the user opens it, he only needs to lift up the barrier curtain 250 to expose the tearing structure.
