Definitions

  • the invention relates to an envelope with a cutting thread according to the preamble of claim 1.
  • Envelopes with a slicing thread can be opened more easily, safely and with less damage to content than conventional envelopes.
  • a thread is guided along an edge in the inside of the envelope and one end thereof is guided outwards.
  • the user can open the envelope in a defined manner by pulling the thread sideways away from the envelope without using an additional tool.
  • the object of the invention is to provide an envelope with a cutting thread, in which the cutting thread can be attached to the envelope in a simple manner.
  • the cutting thread is positioned and fixed simultaneously and in the same operation with the gluing of the side flaps. In this way, slowing down of the production process is avoided.
  • the additional outlay on equipment is minimal and easy to integrate into the existing production, as the fastening thread in the existing system.
  • the cutting or tearing thread can best be attached and held by being soaked or coated with adhesive. After the thread has been introduced and hardened, the adhesive must have sufficient elasticity so as not to impair the normal behavior of an envelope. Inserting a self-adhesive thread has the advantage that the supplied thread can pass through a soaking device before being cut off.
  • the thread can be fed in endlessly and cut to corresponding lengths, the length being able to proceed when the thread is already positioned. It then holds in place due to the adhesive effect and does not impair the subsequent folding of the flaps and further processing of the envelopes.
  • the advantage is obtained that the cutting thread is held securely until it is finally folded and therefore does not fall out. In addition, it is inserted more or less tightly, which has an advantageous effect on the tearing process.
  • a self-adhesive tear thread can also be inserted transversely to the direction of advance of the envelopes during the production process, which is normally done on the lower edge opposite the opening flap.
  • the cutting thread is carried out from the envelope on one side edge.
  • it can be glued on the end. It can also be attached to a flat side near the end of the thread.
  • This attachment is provided in the form of an adhesive point or strip, for example a sticker or a solidified drop of an adhesive substance, which covers the preferably tightly lying thread.
  • An adhesive strip can cover the entire length of the thread. Leading the thread out of the envelope makes it easier to grasp the thread. Fastening the thread section led out near the thread end enables the user to locate and grip the thread safely and secures the thread during transport.
  • the manner of attachment with the aid of an adhesive dot or strip can also be used for advertising purposes, which inevitably draws the user's attention. This is reinforced by advertising-effective design.
  • the end opposite the led-out end can optionally also be led out or remain in the adhesive area of the side flap. In the latter case, deflection and leakage in the adhesive area are possible.
  • Another embodiment provides for perforating the envelope at the cutting edge in order to support the cutting with the thread.
  • the thread is designed in such a way that it is not more raised than possible Folded edges of the envelope. This can be done by appropriate selection of a cutting thread material or by means of a tape, the thickness of which is smaller than the fold edge and which is parallel to a cover surface with a broad side.
  • FIG 1 shows an envelope designed according to the invention from the back.
  • Fig. 2 shows a second embodiment of an envelope according to the invention.
  • An envelope 1 with an adhesive closure flap 2 has glued side flaps 3.
  • a cutting thread 4 is guided along the inside of the cutting edge 5, led out laterally from the envelope and fastened on the back with an adhesive point 6.
  • the cutting thread 4 with its sections 7 is guided through the region of the side flaps 3 being glued to the rear wall.
  • the end 8 of the cutting thread, which is opposite the led-out end, is flush with the edge of the envelope. From this end, the slicing thread 4 runs in a straight line, tension-free and play-free, to the opposite turn-over edge and from there to the glue point 6.
  • a short end section 9 protrudes from the glue point 6.
  • the thread 4 can be inserted loosely and fixed by the rubber coating when the side flaps (not shown) are folded over.
  • the thread 4 can be impregnated with a suitable adhesive or be coated, this self-adhesive property of the thread 4 already developing when it is inserted, so that the thread can be positioned in this way so that it retains its position during further processing of the envelope.
  • the blanks for producing the envelope 1 are shingled in a direction which runs transversely to the lower or upper edge.
  • the feed device for the thread must therefore insert it transversely to the running direction.
  • the short end section 9 is gripped and the stop 6 is detached from the envelope 1 with its help.
  • the stopping point 6 serves as a comfortable handle for the cutting thread and is brought away from the envelope into the plane of the envelope.
  • a movement of the adhesive point together with the cutting thread in a direction parallel to the cutting edge 5 causes the letter to be cut open. Because of the anchoring of the cutting thread 4- to the end 8, the letter can be opened completely.
  • a partially illustrated envelope 1a is provided, which is similar in structure to that according to FIG. 1. It can be seen that the thread 4a is inserted on one side edge. This has the advantage that the thread can be fed in the feed direction and then, if necessary, can be cut off after positioning above the blank. The thread can therefore be inserted and fixed in the course of the envelope production without any change in the basic sequence must become.
  • the thread 4a is preferably self-adhesive. It is therefore soaked in a supply roll when it is unrolled before it is positioned and cut off. The self-adhesive thread 4a therefore holds itself during the further assembly of the envelope la and, moreover, enables it to be fixed securely, which makes tearing open easier.
  • the adhesive of the thread is chosen so that it does not become too hard and breaks after curing.
  • the inserted thread 4 or 4a is very thin, so that it does not lead to a raised edge in the area of the thread after the envelope has been assembled.
  • the end of the thread that is led out is also glued in the embodiment according to FIG. 2 by a plate 6a made of paper or the like. It can be printed with advertising.
