Description

[Detailed description of the invention] [Industrial application field] This invention is a paper used to cover the top surface of synthetic resin bottle cases used to transport multiple bottles of beer, youth, alcoholic beverages, etc. It concerns the lid.

[Conventional technology]

Conventionally, in cold regions such as Hokkaido, for example, to prevent drinks such as beer from freezing in the winter, a paper lid made of cardboard or the like is fitted into the upper opening of a synthetic resin bottle case A to cover it, as shown in Figure 4. It is becoming popular.

This paper lid has a downwardly bent side wall 32 on a pair of longitudinal side edges of a rectangular top wall 31, and a top wall 3
A pair of end walls 33 bent downward are connected to a pair of end edges perpendicular to the side edges of 1, respectively, and the side walls 3
2 and the end wall 33 are inserted into the inside of the bottle case A, the top wall 31 comes to be substantially aligned with the upper edge of the bottle case A.

A plurality of small triangular notches 34 are provided at the lower edges of the side wall 32 and the end wall 33 to engage with the partition frame 41 of the bottle case A.
2, two rows of slits 35 are provided for inserting the transport hooks of the automatic transport machine, and by inserting the transport hooks into these slits and hooking the hooks on the upper edge of the bottle case, the bottle case can be suspended. There is.

[Problem that the invention attempts to solve]

However, in this conventional bottle case paper lid, the side wall and end wall are only in contact with the bottle case, and the locking performance is poor, and the paper lid may be blown away by the wind during distribution or storage. When the transport hook is inserted into the slit 35 and then pulled out, there is a problem that the transport hook lifts up and falls out of the bottle case.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention provides a non-return flap that bends upwardly at the lower end of the end wall, and forms a central upper end of the non-return flap higher than both ends. The upper end of the center portion is brought into contact with the downward facing surface of the bottle case wall opening, and both end portions are brought into contact with the inner surface of the bottle case wall surface.

[Effect]

According to this invention, the non-return flap tends to fall down naturally due to the outward restoring elasticity of the material due to the fold line, and the center part of the upper end enters the wall opening that serves as the handle hole for the bottle case. (Refer to Figure 3), both ends of the upper end come into contact with the inner surface of the wall of the bottle case, thereby ensuring that the bottle is not pulled out.

〔Example〕

1 to 3 show examples of this invention. This bottle case paper lid has a pair of side walls 3 extending in the longitudinal direction of a rectangular top wall 1 made of thick paper such as cardboard, and a pair of side walls 3 bent downward through a fold line 2. A pair of end walls 5 which are bent downward through a fold line 4 are connected to a pair of end edges perpendicular to the side edges, and a pair of end walls 5 which are bent upward through a fold line 6 are connected to the lower edge of each end wall 5. A stop flap 7 is provided in succession, and a gluing margin 8 is provided protruding from both end edges of each side wall 3.

The top wall 1 is formed to a size that fits snugly into the upper opening of the bottle case A, and is provided with two I-shaped slits 9 perpendicular to the fold line 2 for inserting two pairs of transport hooks. To facilitate this, a pair of parallel fold lines 10 are provided at the ends of the slit 9.

The side wall 3 and the end wall 5 have the same height, and the gluing allowance is 8.
When affixed to the inner surface of the end wall 5, a rectangular cylinder inscribed in the bottle case A is formed. A plurality of small triangular notches 11 are provided at the lower edge of the side wall 3 at equal pitches to engage with the lattice-like partition wall 41 of the bottle case A, and are used to fold the prismatic cylindrical paper lid into a flat body (not shown). A diagonal fold line 12 inclined at 45 degrees is provided starting from both ends of the fold line 2, and an I-shaped slit 13 for inserting a pair of conveyor hooks is provided at a position extending to the slit 9 of the top wall 1. A thin through hole 14 connected to the slit 9 is provided at a position along the line 2 to facilitate insertion of the conveyor hook. The slit 13 is provided with a pair of fold lines 15.

At the boundary between the end wall 5 and the non-return flap 7, a plurality of expanded diamond-shaped through holes 16 are provided at equal pitches so as to straddle the fold line 6 and engage with the partition wall 41 of the bottle case A.

The non-return flap 7 is provided with a pair of notches 17 of a required length inward from the free end, with a main tongue piece 18 having a high height at the center and secondary tongue pieces 19 having a low height at both ends. is formed.

As shown in Fig. 3, this paper lid is fitted into the upper opening of the bottle case A, and the top wall 1 is attached to the top of the bottle.
When brought into contact with each other, the check flap 7 naturally falls outward due to the restoring elastic force of the material generated at the fold line 6, and the sub tongue piece 19 comes into contact with the inner surface of the wall of the bottle case A. However, the main tongue piece 18 having a high height protrudes into the handle hole 42, and its upper end abuts against the downward surface of the handle hole 42, thereby ensuring reliable retention.

Note that since the downward facing surface of the handle hole 42 is relatively wide, even if the outward inclination angle of the main tongue piece 18 changes somewhat, there is no problem in preventing it from coming off.

In general, if the non-return flap 7 has a notch 17, the engagement of the main tongue piece 18 with the bottle case handle hole will be better, but it is also possible to eliminate the notch 17 and simply make the center part higher to form the main tongue piece. . In addition, in the case where a notch is not provided, it is important that the amount of protrusion of the central main tongue piece from both ends is large. Also,
The amount of protrusion of the main tongue piece 18 from both ends or the cut length 17 is related to the angle at which the non-return flap 7 falls outward due to the restoring elastic force during use. decide.

In addition, when using the bottle case paper lid of the present invention using corrugated cardboard as a material, as shown in FIG. Strong repulsion and effective.

The paper bottle lid of this invention can be used for paper lids for beer bottle cases, paper lids for soft drink bottle cases such as youth, paper lids for dairy bottle cases, paper lids for 1-sho bottle cases such as soy sauce, etc. Applies to.

When using the bottle case paper lid, the non-return flap 7 is erected in a swinging state about the fold line 6, and the non-return flap 7 is inserted into the bottle case until the top wall 1 contacts the bottle. main tongue piece 18
It falls down due to the restoring elasticity of the material generated at the fold line 6 and enters the handle hole 42, and the upper edge hits the downward surface of the hole, that is, the ceiling surface. At this time, the secondary tongue piece 19 is inscribed in the wall surface of the bottle case A, and this appropriately limits the outward fall of the main tongue piece 18 due to the restoring elastic force, so that the main tongue piece protrudes out of the handle hole. When removing this paper cover, it can be easily pulled out by pushing the main tongue piece by hand to disengage it from the handle hole. Note that this paper lid can be folded into a flat body in one movement from the diagonal crease line 12, making it convenient for transportation and storage.

〔effect〕

As described above, the bottle case paper lid according to this invention has a check flap that bends upwardly connected to the lower edge of the end wall, and the center part of the upper end of the check flap is formed higher than both ends. When fitted into the upper opening of the bottle case, it provides reliable locking performance, and can be attached to and removed from the bottle case with a single movement. There is also an effect that it is possible to prevent the transport hook from falling off when the transport hook is pulled out after being inserted by the automatic transport machine.
