RU2309103C2 - Package for electric lamp bulb - Google Patents

Abstract

FIELD: electrical industry, particularly packages for ampoules, lamp bulbs and electronic valves or tubes.

SUBSTANCE: package comprises blank with two cuts to create two flaps along fold lines. The flaps have identical orifices for lamp case receiving. Cuts are created at flap bases. The flaps are formed in non-adjacent fold lines. Fold lines of each flap are in single plane and made as two segments extending from flap cut ends to adjacent longitudinal fold line and makes an angle α of 52-58° with longitudinal fold line. Each orifice is symmetric about longitudinal fold line including said orifice.

EFFECT: improved package appearance, increased strength and provision of automated bulb packing.

Description

The present invention relates to the electrical industry, in particular, improves the packaging of electric lamps.

A package of electric lamps is known, containing a blank with slots for forming a tongue along the inflection line with a hole for placing the lamp base (Av. St. No. 1507670, dated 10.12.87, class B65D 85/42).

The advantage of this package is the relatively low consumption of packaging material.

The disadvantage of this package is the relatively low strength of the package.

The closest in technical essence is the packaging of electric lamps, containing a workpiece with slots for the formation of two reeds along the inflection line with the same holes for the lamp base (Damn. Live. 323122.013).

This technical solution, taken as a prototype, has a low consumption of packaging material, but insufficient packaging strength during transportation. In addition, in this package, it is necessary to carry out the length of the tongue more than the distance from the maximum diameter of the bulb to the lamp base, otherwise it is very likely that the bulb will deviate into the cut outside the packaging of some lamps. When placing several lamps in a box, the probability of their destruction is high.

The objective of the invention is to expand the scope, increase the strength of the package during transportation and the possibility of mechanization of packaging lamps.

This goal is achieved by the fact that in the packaging of electric lamps containing a blank with slots for forming two reeds along the inflection lines with the same holes for placing the lamp base, slots are made at the base of the reeds, the reeds are made on non-adjacent longitudinal inflection lines, the recess lines of the tongue are made on at the same level in the form of two segments from the edges of the slot of the tongue to the adjacent longitudinal line of inflection and make an angle α with a longitudinal line of inflection, which is in the range of 52-58 °, each hole e formed symmetrically about the longitudinal fold line on which it is formed.

The proposed package allows due to the formed stiffeners on the tongue to significantly increase the strength of the package.

A slot at the base of the tongue makes it easy to form the tongues without violating the integrity of the package. Placing the reeds on the longitudinal lines of the inflection of the package allows you to expand the scope of this design for various lamps, ensuring their safety.

In the proposed design, the probability of deflection of the flask into the section outside the packaging is absent, because due to the sufficient rigidity of the package, it is not necessary to carry out the width of the tongue more than the diameter of the bulb, and the bulb always rests on the packaging when performing any length of the tongue.

Figure 1 shows the blank 1 of the packaging of electric lamps with slots 2, 3 for the formation along the bend lines 4, 5, the tongue 8 with the hole 10 and along the bend lines 6, 7 of the tongue 9 with the hole 11. At the base of the tongues made slots 12, 13 The tongues are made on non-adjacent longitudinal inflection lines 14, 15. The inflection lines 4, 5 and 6, 7 are made at the same level, in the form of segments from the edge of the slot at the base of the tongue to the adjacent longitudinal inflection line 16 and make an angle α with the longitudinal inflection line, between 52-58 °.

Holes 10,11 are made symmetrically with respect to the longitudinal inflection line 14, 15, respectively.

To assemble the box, the opposite sides of the workpiece are glued with adhesive tape, or they are performed on the folding bend 17 and the packaging sides are glued with it.

The tongues of the packaging after assembly of the box are folded inward. In this case, the tabs overlap each other

Figure 2 shows the packaging in assembled form from the side of the longitudinal line of inflection, on which the tongue is made.

Figure 3 shows the packaging in assembled form from the side of the longitudinal line of inflection, on which there is no tongue.

Figure 4 shows the packaging, a bottom view, which shows the bent tabs 8, 9 on the longitudinal lines of the inflection 14 and 15, respectively.

When reeds are made on adjacent inflection lines, the packaging is relatively less durable due to the small distance between the reeds.

When the reeds are performed not on the longitudinal inflection lines, the strength of the reeds decreases.

Slots for tongues, made on the same level in the form of two segments, comprising angles α within the range of 52-58 ° with the inflection line, allow tongues to be formed by laying them on top of each other, increase stiffness, reduce force when the lamp is inserted into the box, allow you to get the opportunity to mechanize the process of packaging lamps.

When making cuts with a bend line of the tongue, which makes the angle α less than 52 ° and more than 58 °, the tongues, while holding the lamp base, experience an uneven load and the packaging strength decreases.

When the hole is made asymmetrically to the longitudinal line of inflection, the holding strength of the base is reduced by the hole and the strength of the tongue is reduced.

The application of the proposed packaging allows you to check the lamps without removing them from the package.

An example of a specific implementation: Packaging for incandescent lamps with a power of 25-100 W in a ⌀ 60 mm canister is 110 mm high, the tongue is 64 mm high, the tongue's notches are 35 mm long, the tongue's notch angle to the inflection line is α = 55 °, the distance between longitudinal bend lines 60 mm, hole ⌀ 24 mm.

The test results of this package showed that it more effectively ensures safety during transportation than packages made by analogue and prototype.

This package has an attractive appearance, which is important for the buyer. Packaging allows you to verify the quality of the packaged lamp and has enough space to put the necessary information on the side surfaces of the package.
