Abstract

(57) [Summary] (with amendments) [Purpose] To ensure that the closed state is maintained when the top lid is closed again after it has been opened. [Structure] A cut line is formed on the ridge line between both sides 2 and 3 and the top surface. At the top of both sides 2 and 3 and near the front 1,
A protrusion 12 protruding inward is formed by embossing. When the top surface 4 that has been opened is to be closed again, the top surface 4 can be locked to the projections 12 by pushing the top surface 4 down over each projection 12.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to paper containers, and in particular, the top surface can be easily broken and opened along the lines. related to paper containers that can be used to securely close the top surface once the lid has been opened. .

0002

[Conventional technology]

Many paper containers of this type have been provided in the past. Figure 5 shows a typical example. There is.

0003 The paper container shown in the figure is hexahedral, with 1 representing the front, 2 and 3 representing both sides, and 4 representing the top. It shows. In order to open the top 4 to take out the items stored in the paper container, open both sides. A cut line 5 is formed on each ridgeline formed between 2 and 3 and the top surface 4. Also , a cut line 6 that is continuous with the cut line 5 is formed on the front surface 1. In this cut line 6 A push-in piece 7 is formed at the upper part of the front surface. In other words, in this configuration, When opening the side 4, push the push-in piece 7 along the cut lines 6. , a part of the pushing piece 7 is broken off from the remaining part of the front surface 1. Then, push it inside the container once. Pull out the pressed piece 7 again and break it along the cut lines 6 and 5. Then, the top 4 is opened.

0004 In the conventional example above, opening the top panel 4 is extremely easy, but once the top panel is opened, When you close the lid, the top surface will have an opening pattern, so even if you close the top panel again, the opening pattern will cause the top to open. There is a problem that the lid opens naturally and does not close completely.

[0005]

[Problem that the idea aims to solve]

Therefore, the technical problem to be solved by this invention is to close the top panel once it has been opened. The objective is to ensure that the closed state is maintained when the

[0006]

[Means, actions, and effects for solving the problem]

In order to solve the above technical problem, the present invention provides a paper container with the following configuration. be done.

[0007] In other words, this paper container has cut lines formed on the ridge line between both sides and the top surface, and , characterized by having protrusions that protrude inward at the top of both sides and near the front. are doing. Each of these protrusions can be easily pressed from the outside to the inside by embossing. can be done.

[0008] According to the above configuration, when the top is opened and then closed again, the top is moved by riding each protrusion. The top surface and the protrusion can be engaged by pressing down beyond the This prevents the ceiling from opening to nature.

【Example】

An embodiment of the present invention will be described in detail below with reference to FIGS. 1 to 4.

0010 FIG. 1 is a perspective view showing the main parts of a paper container. In the figure, 1 is the front, 2 and 3 are both 4 is the top surface, and 13 is the bottom surface. There are cuts on each ridgeline between both sides 2 and 3 and the top 4. Ruled lines 5 are formed. In addition, a fold line 4a is formed between the ends of each cut line 5 on the top surface 4. has been completed.

[0011] A tension piece 10 that covers the top of the front surface 1 is connected to the front edge of the top surface 4. . This pulling piece 10 has a roughly triangular shape, and a knob 10a extends from its central front end. are doing.

0012 On the other hand, in the upper part of the front surface 1, a cut line 6 is formed which connects to each of the above-mentioned cut lines 5. Ru. This cut line 6 is a cut that is cut out together with the pull piece 10 when the top panel 4 is opened. The area 1a is separated from the rest of the front surface 1. The cutout area 1a is as shown in the figure. As shown in the figure, the cut line 6 is slightly smaller than the tension piece 10 It is configured to be completely hidden by the pull piece 10. This is best shown in Figure 2. As shown in FIG. It is embodied.

[0013] At the top of each side 2, 3 and near the front 1, there is an embossed protrusion that protrudes inward. It is formed by processing.

[0014] In the configuration shown in Figures 1 and 2, pull the knob 10a forward on the front surface 1 as shown in Figure 3. When the cutout area 1a is pulled up and then pulled upward, the cutout area 1a will first be drawn along the cutout line 6. The top surface 4 is broken along with the tension piece 10 along the cut line 5, and the top surface 4 is broken along the both sides 2. , 3. As described above, according to the paper container having this configuration, the pull of the knob 10a The top surface 4 can be easily opened by only tensioning the lid.

[0015] Next, when the opened top surface 4 is to be closed again, the procedure shown in FIG. 4 may be performed. vinegar That is, the opened top surface 4 is pushed downward from the position before the lid is opened, and both side walls 2 and 3 are At the same time, the shape is placed near the knob 10a of the tension piece 10. The front upper part or The bottom of the notch 1b is pushed down to be inserted. Then, pull The upper edge of the front surface 1 is held by the double wall portion of the strip 10, and each protrusion 12 This ensures that the top surface 4 is prevented from rising naturally. So a very simple configuration This allows the top surface 4 to be completely closed.
