Abstract
The peripheral wall of a box is formed as a band with abutting ends (12,13) at a joint (35), the abutting ends being secured together by means of a tongue (26) which is provided at one end of the band entering into a recess (30) provided at the other end of the band. Preferably, the tongue (26) is formed as an extension of a lateral marginal portion (24) of the band-forming material which is folded over the adjacent main portion (11) thereof, and the recess (30) being defined between the folded-over marginal portion (24) and the adjacent portion (11) at the opposite end (12) of the band. Preferably also end portions (16,17) of the band are folded inwardly at the joint (35).
Claims15
A box comprising a peripheral wall formed from a continuous strip of material having longitudinally opposite ends wherein:
- lateral marginal portions of said material are folded over adjacent portions of the strip between said marginal portions and do not overlap one another, the lateral marginal portions being adhesively secured to said adjacent portions;
- the folded marginal portions at one of said ends of the strip defining in combination with said intermediate portions a recess;
- the other of said ends of the strip is formed with a tongue which is adapted to enter said recess, the ends of the strip being in abutting relation to form a joint with said tongue located in said recess;
- and
- the tongue and the recess each comprise two parts associated with the respective longitudinal portions.
A box comprising a peripheral wall formed from a continuous strip of material having longitudinally opposite ends wherein:
- at least adjacent to one of said ends of the strip a lateral marginal portion of such material is folded over an adjacent portion of the strip and adhesively secured thereto;
- the folded marginal portion at one of said ends of the strip in combination with said adjacent portion defines a recess;
- the other of said ends of the strip is provided with a tongue formed as a separate piece of material secured to the strip and adapted to enter said recess, the two ends of the strip being in abutting relation to form a joint with said tongue located in said recess.
A box comprising a peripheral wall formed from a continuous strip of material having longitudinally opposite ends, wherein:
- a lateral marginal portion of such material is folded over an adjacent portion of the strip and adhesively secured thereto;
- the folded marginal portion at both of said ends of the strip defines in combination with said adjacent portion respective recesses;
- the two ends of the strip being held in abutting relation to form a joint by means of a connecting piece which is secured in the recesses.
A box comprising a peripheral wall formed from a continuous strip of material having longitudinally opposite ends wherein:
- a lateral marginal portion of such material is folded over an adjacent portion of the strip and adhesively secured thereto;
- the folded marginal portion at one of said ends of the strip defining in combination with said adjacent portion a recess;
- the other of said ends of the strip is formed with a tongue which is adapted to enter said recess, the two ends of the strip being in abutting relation to form a joint with said tongue located in said recess;
- and
- portions of the material at the opposed ends of the strip are folded over and secured to adjacent portions thereof prior to the folding over of the longitudinal marginal portions to form a double thickness abutting edge at the joint.
