FR2754996A1 - Pot to hold flower arrangement - Google Patents

Abstract

The pot is made in injected synthetic material and heavy material (6) is moulded in it. A vertical rib (5) projects from its lower surface (3) and vertical ribs (6) project from its lateral conical wall (4). The ribs can fold at their base (P) to hold for solid filling material. The folding zone is between a wider base part and a narrower upper part (5a,6a) and the upper part is bent downwards to a horizontal position. The lateral ribs limit the penetration of another pot.

Description

 The invention relates to a pot for flower arrangements.

 To produce floral compositions, it is known to use pots of injected synthetic material in which are placed a filling and ballasting material and a means for pricking the stems of the elements of the floral composition. The filling and ballasting material is generally made up of plaster, cement or foam which is introduced into the pot in a liquid or pasty state, then solidifies. This solidification causes a shrinkage which, in combination with the frustoconical shape of the pot, promotes the separation of the pot and the filling and deteriorates the quality of the final product.

 The ribs made in the bottom of each pot to limit the engagement of another pot and thus avoid the jamming of the two stacked pots, also have undercut faces which promote this separation.

 To remedy this, it would be possible to produce undercut parts in the pot, but this would entail additional molding costs, incompatible with the low production costs sought.

 The object of the present invention is to remedy these drawbacks by providing a pot, inexpensive to produce and providing means ensuring a positive connection with filling and ballasting materials.

 To this end, the pot according to the invention comprises projecting from the internal face of its bottom and / or from its frustoconical side wall, at least one vertical rib locally comprising a folding zone to form, after this folding, a retention of solid filling and ballasting material.

 Thus, this pot is moldable according to the same techniques as current pots but includes, in the extension of its ribs, tongues which can be folded, at right angles or more, manually or by the mere stacking of the pots at the machine outlet, to form organs which, after pouring the filling material and solidifying it, positively retain this material in the pot and thus improve the general quality of the floral composition.

 In one embodiment of the invention, the folding zone is determined by the transition zone between a part of larger section and a part of smaller section of the corresponding rib.

 This arrangement makes it possible to form a folding zone without having to modify the draft angles and above all without having to resort to external means generating undercuts, therefore while respecting the search for low production costs.

 Other characteristics and advantages will emerge from the description which follows with reference to the appended schematic drawing representing several embodiments of the invention.

 Figures 1 to 3 are partial side views in cross section of the bottom of a pot according to the invention, respectively after demolding, when stacking another pot and after pouring and solidification of the filling material.

 Figure 4 is a partial cross-sectional view showing an alternative embodiment of the pot.

 In these drawings, the reference numeral (2) generally designates a jar of injected synthetic material composed of a bottom (3) and a frustoconical wall (4). In known manner, to limit the engagement of another pot during the stacking of the pots, each pot comprises either an axial rib (5) projecting from its bottom, or peripheral ribs (6) projecting from the internal face of its wall (4), or finally the two types of ribs.

 According to the invention, one or both of these types of ribs has on its height a folding zone (P) separating the rib from an upper tongue, respectively (5a and 6a), which can be folded substantially at 90 degrees compared to it. This tongue has a smaller cross section than the section of the rib which it extends and it is precisely the transition zone of these different sections which forms the folding zone (P).

 Figure 1 shows that these tabs (5a and 6a) also have undercut faces in no way opposing the release of the pot (2) after injection.

 Figure 2 shows that when stacking the pots, the bottom (3a) of the pot (2a) which enters the pot (2) comes into contact with the tabs (6a) and gradually tilt them at right angles to that the bottom of the pot (2a) comes to rest on the tabs (6). This is made possible by the spacing (7) formed between each tongue (6a) and the internal face of the frustoconical wall (4) of the pot, but also by the fact that the folding zone (P) of each rib is arranged. substantially at the horizontal level (H) of the support in this pot (2) from the bottom of the pot (2a).

 The tongue (Sa) which, in this embodiment is at a level lower than that of the tongues (6a), but which can moreover be at the same level, is folded manually before using the pot.

 It therefore appears that before pouring a liquid or pasty mixture of plaster, cement or foam into the pot, the operator must first check the folding of the tabs.

 After solidification of the filling and ballasting material (8), and as shown in Figure 3, the cake formed in the bottom of the pot is perfectly retained in this pot by the folded parts (5a and 6a) which form retention hooks .

 The embodiment shown in Figure 4 differs from the previous one in that the retention members are constituted by the ends (9a), of smaller diameter, of stepped tubular bodies (9) projecting from the bottom (3) of the pot.

 As in the previous embodiment, these ribs with foldable tabs at 90 degrees or more, can be produced by simple molding means and do not outbid the cost of manufacturing a pot, while making it possible to obtain, after folding the tabs (9a), means for retaining the wafer (8) of the filling material.
